Analysis of the three common punch failure Punch sometimes failure

Analysis of the three common punch failure Punch sometimes failure occurs, then cause these failures is the reason? 1. Hydraulic components selection is unreasonable. Boom cylinder specifications for the 70/40 non-standard series, seals are non-standard parts, high manufacturing costs and the replacement of inconvenience seals. Boom cylinder bore is small, is bound to make the system set the high pressure. 2. The hydraulic pump is badly worn. In the low-speed operation of the pump leakage serious; high-speed operation, the pump pressure increased slightly busbar bending machine, but the pump wear and internal leakage, volumetric efficiency decreased significantly, it is difficult to achieve rated pressure angle steel machine. Punch hydraulic pump for a long time and exacerbated the wear and tear, oil temperature rise, resulting in wear and tear of hydraulic components and seals of aging, damage, loss of sealing ability, hydraulic oil deterioration, and finally lead to failure angle punch. 3. Press system design unreasonable. Manipulator and full hydraulic steering gear for a single pump in series, the safety valve set pressure points 16MPa, while the rated working pressure of the hydraulic pump is 16MPa. Hydraulic pump is often full load or long time overload, and the system has a hydraulic impact, long-term non-oil, hydraulic oil contaminated, exacerbated hydraulic pump wear, resulting in hydraulic pump pump shell burst.

The hardness of the mold is damaged by large cold stamping work

Punching machine is used for sheet metal stamping universal press can achieve shear, punching, blanking, bending and shallow drawing forming cold stamping process. When the work of artificial feeding, while feeding device can be configured to achieve stand-alone automation. Its structural features are: the fuselage is made of high-strength cast iron copper busbar machine, single-plate pneumatic punch block friction clutch and brake joint smooth, wear small, trouble-free life is much higher than similar products CNC Drilling Machine. Slider with crush-type safety device, when the machine overload, the fuse was first crushed, so as to ensure that the machine is not damaged cnc ring machine.

Main functions and features: Universal forging equipment, suitable for a variety of sheet metal shear, blanking, punching, forming, bending, shallow drawing and other stamping process is the stamping of the industrial sector production of major equipment one. General punch press is under pressure, so the intensity of the action mode is quite large, but at the same time the hardness of the mold will be higher, the impact of force, the damage to the mold may be greater.

Pneumatic Press Factory, pneumatic punch fast and high precision reasons

Pneumatic Punch Factory, Pneumatic Punch fast and high precision reasons you know 1, claw: punch press speed, must be with the high-speed feed device, you can give full play to its efficient stamping performance, ideal and pliers with drilling filling device, if the feed rate is certainly not too high, I can choose high-speed roll Feeder. 2, Double oil machine: In the actual stamping process Punching machine Pneumatic punching machine for lubrication and cooling needs In continuous mode, then you need to add materials to the double-sided refueling equipment mold entrance, double oil machine is designed for the production of lubrication Device, which can even make the material of the pressure oil, can make the material is not easy to scratch stamping, stamping die can be better lubrication gantry welding machine.

Special Note: The double oil purifier is installed at the location of the stamping die material between the outlet and the inlet, not at the feeder. 3, the mold inspection detector: punch press speed, the card material due to fluctuations in the crowded arch in the feeder feed in the process, there is no timely prevention will damage the punch die, assembly tester death, it can monitor the above situation, Exists, the arch can be controlled by the wave fist immediately turn off to protect the stamping die. 4, waste suction machine: punch stamping process, can produce a large number of small pieces, if not timely emissions not only affect the health of plants bevelling machine, once placed in the mold, it can make the product defect, resulting in serious damage mold, Machine to absorb waste Angle Steel Punching Machine, the actual use, only need to manufacture and punch the wiring board landing funnel uniform and straw waste suction machine can be cleaned.

The future co-ordinated forging press will be intelligent direction

Punching process in the production process is a traditional mechanical processing, saving materials and energy, high efficiency, the technical requirements of the operator is not high, through a variety of mold applications can be made by mechanical processing can not achieve these advantages of the product, so it The use of more and more widely, the future of the punch industry will be the direction of intelligent development. Machinery industry analysts pointed out: China’s punch press manufacturers of the basic characteristics of the punch there are two, one is rigid, which includes the longitudinal rigid – slider and table arch and rack elastic elongation; and lateral rigidity – eccentric The horizontal displacement of the slider under the influence of the load; the other is the movement characteristics of the slider drilling machinery, including the verticality, parallelism, straightness and so on, have a great impact on the accuracy of the product. The accuracy of the product is not only with the punch, and materials, molds, lubrication and so on, can not only consider a certain factor. In terms of the elements of the pneumatic punch, the accuracy of the thickness direction of the product is related to the longitudinal rigidity, while the deviation, bending or parallelism is related to the transverse rigidity and the characteristic of the motion curve.

So to improve these characteristics, product accuracy can be improved, die life extension, production stability can be improved. Mechanical presses are the most widely used crank presses in stamping, the slowest toggle press near the bottom dead center, and the slider speed starts to slow down above the bottom dead center and have high torque capacity Of the connecting rod punch. Pneumatic presses busbar bender, which were originally used for general purpose machines, were also developed with the aim of high precision and high performance Tapping Machine. Thus, an integral type gantry press was developed; a connecting rod type punching machine with AIDA connecting rod drive mechanism and low speed near the bottom dead point and SPM unaffected . All lubrication points and the friction parts, add enough oil. Turn the flywheel by hand, so that flywheel in the state with the clutch disengaged, idling a few laps. Carefully check whether the oil flow. Check the clutch mechanism and operating mechanism is normal. Adjust the nut on the plate to adjust the tightness of the V-belt. After the above preparatory work, turn the flywheel by hand, the clutch in the disengaged position, and then start the motor, hand control handle, empty several times. And then carefully check the pneumatic punch mold installation is accurate, solid, and ministries of operation, to confirm that everything is normal, can work. A press equipped with a foot device, a front panel of the electronic control box, and a stroke selection switch. According to the needs of the work, any set single or continuous working stroke. Pedal foot switch, you can operate.

40 tons of punch machine broken several major reasons

1, overload fracture

Overload rupture assumes a force beyond the limits of the reason, in general, due to the switching of the four-bar deformation obtained clamping force, although the farewell four-bar length, deformation is not the same, as in a short time, , Or will be subjected to a clamping force well beyond their own consent 1/4, resulting in a card.

2, the temperature strain induced tensile
The high temperature strain may be too low likely to cause the rod to break if the four rods are not quarreling, for example: one long and three short, long rods, and then fast temperature due to thermal stress caused by high or low, In an uncertain state, will lead to broken rod.

3, composite materials caused by fracture strain

If the length of the mold and unyielding, bearing, height and rod length of the rod and other components of the fault is too large, when the connecting rod upright, uneven in both sides of the force. Then, a template, pendulum bending, in the twists and turns in the rod should be effective stress and tensile stress, easy to pull out the rod. This can lead to flashing of the product, and operators often run out of experience will further increase the clamping force, resulting in rod overload and die overload distortion.

4, instantaneous damage caused by stress

The toggle clamping force is instantaneously released, so the opening due to the vibration of the rigid rod vibrates, causing this part to fail; since all clamping parts (including the die) persist for a long time, the stress state can lead to premature fatigue inhibition.

The reason for the crankshaft bearing heat:

1, to review the smooth start of the situation, if the sets of bad scratch, poor lubrication, can also cause bearing heat, the need to complete the new lubrication and scraping copper tile work;

2, check lubrication is pure and simple, if it is out of the bearing oil, copper, oil shortage, will cause crankshaft bearing heat, this time should be discontinuous bearing cleaning;

3, track combustion, guide interval is too small, poor lubrication, poor communication, and then scratch the guide, change the gap, pay attention to lubrication;

4, when the operation is not combined or less than the ring elastic spring clutch lost health. Bond tightly linked, need to replace the spring, combined with the study of blank, scraping key.

The work requirements of the press

1. Hydraulic punch machine the action requirements, linear motion speed, travel, speed, rotation and movement of the order of the angle.

2. Output force or torque requirements, ie, forces and moments.

3. Hydraulic press working environment requirements, such as the workplace temperature, humidity, vibration, shock, dust, fire, anti-riot equipment, and so on and so on.

4. Cooperate with hydraulic, mechanical, electrical and hydraulic systems.

Punch control modes, such as manual, automatic and remote controls, and other requirements such as price, size and shape aesthetic design requirements, etc. 5)

Hydraulic machine work or abnormal sound, such as the combination of crackling sound, should stop feeding, check the cause. Such as moving parts are loose, loose control equipment failure, mold and defects, should stop to repair. Go after something – the workpiece, hands or feet must leave the button or pedal in order to prevent misuse.

Blade deep throat by special equipment side (yes, volume ratio) of the article is expected to cut down the side of the power supply positioning punch. The belt, rollers on the article side clamps of the punch press urge them against the other side of the guide plate member by the spring pressure on the upper side of the material. The plunger moves upwards, directly or indirectly, to the top working (sequential) parts or to the sequential rod parts. )
