Production line equipment composition introduction

Process flow: Longitudinal beam preparation→longitudinal electromagnetic automatic feeding→longitudinal material automatic positioning→tail end clamping and auxiliary clamping→workpiece enters the punching host and processed→feed end clamping, auxiliary clamping and processing→punching Finished→Workpiece electromagnetic automatic unloading

The processing method is filter type, that is, the longitudinal beam only feeds forward when punching.

The structure of each mechanical device:

1. Longitudinal beam bearing electric trolley:

The trolley can be controlled by buttons to drive out of the line, and after loading the pallets hoisted by the crane, it will drive back to the loading position;

The load of the trolley is not less than 20 tons, and the stroke is 1.5 m.

Electric trolley

2.Electromagnetic sucker automatic feeding device

  The device is composed of bracket, moving beam and its driving device, suction cup beam and lifting device, suction cup control system, etc.;

  There is a plate detection rod on the suction cup beam, which can automatically stop when it reaches the height of the plate, and can detect whether there is a plate and whether it is sucked, and the work is stable and reliable;

  The lifting and lowering of the suction cup beam is guided by a guide rod to ensure synchronous lifting; the moving beam has good rigidity, and the front and rear movement is guided by a guide rail to ensure synchronization at both ends;

The electromagnetic chuck maintains the electromagnetic force when it is off, and reverses the demagnetization when it is energized, which is safe and reliable.

3.Longitudinal support roller table

Composed of a base and a supporting roller to support the sheet;

Both ends of the roller are supported by bearings, the roller has good rigidity and impact resistance, and the sheet moves on it;

4.Centering device

  There are 5 sets of centering positioning devices, and the two centering blocks are synchronously driven and guided by guide rails. When in use, the cylinder drives two pairs of centering blocks to move towards each other and center the clamping sheet; Line positioning can make the width error distributed on both sides.

5.X-axis main clamp feeding device: 2 sets

     The device is composed of servo motor, precision reducer, floating hydraulic clamp, precision linear guide rail, precision rack and support; the servo motor drives the helical gear to rotate through the precision reducer, and converts the rotary motion into linear motion through the rack. The precise feeding of the feeding parts is completed through the precision linear slide rail guide, and the sheet feeding is accurate and stable; the feeding clamp is a floating clamp, which can have good adaptability to some warped sheets, and the clamping force Large, reliable clamping, stable work.

Push-pull clamp. The clamp clamps the middle part of the two ends of the longitudinal beam. This clamping method can clamp the plate with a drop on the edge of the plate; the two sides of the host are arranged symmetrically.

6.X-axis auxiliary clamp feeding device: 2 sets

The device is used for processing the head and tail ends of the beam, and there are one set on each side of the main machine, consisting of hydraulic clamps, base and driving parts;

During the entire workpiece feeding process, when the clamp on the feeding side cannot hold the sheet but still punches holes, in order to ensure the accuracy of the punching position, the sheet should continue to have more than two clamping points, and In the process of changing the clamping point, the change of the positioning reference is not allowed. In this case, the auxiliary clamping device effectively solves this problem. Under the push of the oil cylinder, the jaws of the clamp clamp the sheet. In this way, under the pressure of the oil cylinder, there is a second clamping point for the sheet when punching (the first is the main clamp on the blanking side), ensuring smooth and accurate feeding of the sheet.

7.Punching host: 1 set, punching force 120 tons

Main machine structure: The stamping main machine is composed of a base, a moving bed, a servo motor screw drive device, a mold system, a pressure unloading device, a stamping cylinder, a pneumatic and a lubricating device, etc.

The bed is a steel plate welded structure, and annealing heat treatment is used to eliminate stress; the slider is guided by a heavy-duty linear guide rail, which can withstand partial load force; the power cylinder drives the slider to stamp up and down, and the stamping stroke of the slider is adjustable, and the mold base can be lifted for easy replacement. mold;

  The pressure and unloading device is separately placed on both sides of the moving bed, swings around the rotating shaft fixed on the bed, and resets with the reset cylinder. The pressure and unloading force is provided by the nitrogen cylinder, the sheet can be flattened, the stamping and mold ejection are reliable, the punching precision is high, and the life of the mold is improved;

Mold structure: the upper mold system is all installed at the bottom of the slider, the punch is installed in the upper mold base, the upper mold base is easy to disassemble, and the punch is equipped with a pushing device to prevent the waste from rebounding;

The stamping host is equipped with 25 dies, 5 dies with a diameter above 25mm, and 20 dies with a diameter below 25mm. Molds are distributed in-line, single row for large molds, double rows for small molds, simple mold manufacturing, easy for users to purchase and process;

Stamping principle: Each punch corresponds to a block and the cylinder that pushes and pulls the block. When the block above the selected mold enters, the punch cannot move up and down in the die hole, but can only break through the sheet; The other punches can move up and return relative to the slider in the die hole after touching the sheet, without punching the sheet.
