The Structure and Advantages of Multi – station Precision Punch

Dec 09
2016

Multi-station precision punching machine is a kind of crankshaft punching machine, which is mainly used for punching production of ring parts of bearing ring blank or similar bearing ring. Multi-station precision punch has the advantage that when the punch is started, the drive system drives the cam to rotate and the roller moves synchronously in its curved groove. The pendulum is driven by the swing lever and the universal connecting rod, The distance between the clamps moves the blank from one station to the next tube drilling machine, enabling the longitudinal movement of the robot and the movement of the workpiece.

 

In addition CNC punching machines, after the press is moved, the up and down movement of the slider drives the flexible force transmitting cylinder to move up and down, and then drives the rocker arm, connecting rod and two parallel shafts to make relative or opposite rotation, and then rotate the arm to clamp and open the clamping plate , The other side of the same mechanism, through the shaft to achieve both sides of the shaft, the arm action step rotation, both sides of the plywood movement coordination, to achieve the lateral movement of the robot, the plywood in a reciprocating cycle of the trajectory is rectangular. So that the workpiece clamp tight and reliable operation, which is simpler than the robot-shaped trajectory and easy maintenance. In addition, the design of the upper block adjustable height of the body can save the original height of the precision punch press screw and its adjustment mechanism big drill machine, and adjust the simple, high precision. Another design of the power out of blank mold release mechanism, when an unexpected power failure, not to die in the mold stuck in the mold and damage.

The multi-tasking system of the electronic cam control device of the punch press will start the state detection and intelligent adjustment system at the same time when the preset control is carried out hole punch for metal. When the punch press is stopped at the appointed time, the point stop control is carried out according to the current punch crank speed and the known braking system characteristic. , And the intelligent monitoring system monitors the actual rotation angle of the punch and compares and analyzes the current braking characteristic state of the braking system according to the actual sliding angle and adjusts and adjusts the stopping control parameter according to the state and intelligence to realize the crank angle Of the real-time detection and control, to ensure maximum punch press production accuracy and stability.

In the use of precision punching machine in the process, the main motor and the punch flywheel is always in the operation of energy storage state, and as the work of the press need to press the need for safe production and moving time to stop, which requires an effective and reliable Brakes, clutches and brakes on precision presses are such braking devices that can control the drive system to engage punch presses or release stops. In actual use, when the need for precision punch press processing clutch production clutch, the flywheel will be through the clutch kinetic energy transmission link connecting rod angle work machine, crankshaft and punch, so that the punch press can drive the mold up and down reciprocating punch production; when the press operation, according to the process Of the need to top dead center, bottom dead center or stop at any position, press the emergency stop button, the clutch will be disengaged, so that flywheel and punch from the transmission mechanism, the flywheel will be idle storage, but because of long time Of the inertia of the flywheel from the transmission mechanism will continue to run at this time if there is no other brake on its braking, or press punch punch will appear with the phenomenon, the manufacturer at this time is responsible for the flywheel will be off After the transmission device to eliminate the inertia of the role of braking to ensure that punch press can immediately stop at the desired location CNC Angle Line, to maximize the punch press to ensure the safety of production. Precision punching clutch brake Precision punching clutch and brake is the fundamental role in the punch main motor and the flywheel does not stop rotating case, according to the punch press control punch press immediately stop, to avoid the mistakenly washed, and even red, is to prevent security incidents, improve punch quality and production Efficiency of the core components. Unlike conventional punching machines, the anchor bolts and the damping ditch are different.

The installation of precision presses and punching machines and shockproofing are all based on the use of a shockproof foot. When you use the shockproof foot, you only need to select the appropriate size according to the tonnage of the press. Fast and convenient, while adjusting the punch level convenient, rapid, and can be adjusted according to the processing needs of the punch position, is the ideal choice for modern processing. Punch speed, vibration, compared to precision punch larger, so the use of the shock-proof foot is not the kind used in precision punch horn, but for the design of the air cushion feet, punch air cushion feet from the plane, air cushion body , The concave part, the edge, the convex fast, the pressure ring, the gas chamber, the air valve component, in which the air cushion body and the convex block use the wear-resisting soft plastic material once shaping to play the good support function, the punch air cushion foot inflates is the bump Point contact rather than the traditional form of earthquake-resistant foot contact to ensure that the ground contact is more reliable and more stable, while the punch air-cushion solid pressure ring to cushion the plane of the plane and close contact with the punch base to ensure that the middle of cushion foot extension was concave formation Tightly sealed air chamber does not leak, so that shock buffer to achieve the best results.

Punch noise reduction project implementation:

1, the workshop reverberation skills and the noise source noise value is determined: reverb craft is the arrival of indoor sound and peaceful way, the sound source to stop the sound after the residual sound in the room between the song shot through the wall to receive, the average sound energy density drooping for the original The odd value of one hundred of the period. The longer the reverberation skill, the evidence of the sound in the workshop repeatedly curved song, slow energy decay slow, under the premise of the same sound source reverberation time longer than the reverberation workshop workshop noise is greater.

2, the selection of sound-absorbing material: sound insulation board composed of five departments, noise qualifications perforated plate hole into the sound-absorbing cotton, part of the vibration of the original glass wool will be sent to correct energy into the heat, punch the other part of the outer plate cut off, Arrival of the idea of ​​sharing. (1) the thickness of 2mm outer steel plate, from the noise and shelter, and the appearance of sound-absorbing panels. (2) the central part of the sound-absorbing panel for the sound-absorbing material, made of glass wool products, for the absorption of sound energy, noise reduction material is the main structure points. (3) fiberboard paste in the external sound-absorbing cotton to prevent the sound-absorbing cotton falling. (4) Transparent film attached to the sound-absorbing cotton warts, from the moisture-proof and sound-proof cotton to avoid the inner perforation of the perforated plate in the role of the net.

3, the sound-absorbing panel sealing control: because the entire production line stagnation is punishing a number of small sound-absorbing panels stitched into a closed body, punch is that the insurance noise reduction in the production of the need to control the birth of a good sound-absorbing panels Between the severance, excellent for 1 ~ 2mm. In order not to let the noise through these cracks came to the role of noise reduction of the harvest, often taking the sealant seal space.

4, ventilation management: because of the deployment of their own operation of the heat, by the sound-absorbing material glass wool insulation properties, the production line inside the blockade after the temperature from time to time than the external high 3 ~ 5 ℃. In the implementation of noise reduction projects, the daily noise in the top wall plan exhaust fan, take away the hot atmosphere of closed space, so that negative pressure inside, the external atmosphere through the noise wall into the interior. In the exhaust fan when the Chinese low-noise fan to avoid contamination of the results of noise.

5, lighting penalties: shade Wei closed after the implementation of the project to set up internal and external workshop lighting partition, which closed the body supply of supplementary lighting system. In order to ensure the production and post-setting requirements of the lighting, planning to reach more than 500 lumens illumination. Close the body of the lighting of a single isolated wiring, parallel switch, to ensure the application and does not affect the original power supply system. In addition, in order to prevent sudden power outages in the workshop, in the closed body to install the material edge emergency lighting system to ensure that the construction of Kazakhstan to build and staff well.
