technical field

The invention relates to the technical field of presses, in particular to a press with high performance and adjustable inclination and a working method.

Background technique

Presses (including punch presses and hydraulic presses) are versatile presses with exquisite structures. With the characteristics of wide application and high production efficiency, the press can be widely used in cutting, punching, blanking, bending, riveting and forming processes. It can be processed by applying strong pressure to the metal blank to cause the metal to undergo plastic deformation and fracture. When the mechanical press is working, the motor drives the large pulley (usually double as a flywheel) through the V-belt, and drives the crank slider mechanism through the gear pair and clutch, so that the slider and the punch go down in a straight line. After the forging work is completed, the mechanical press The slider is upward, the clutch is automatically disengaged, and the automatic device on the crankshaft is connected at the same time, so that the slider stops near the top dead center.

When the existing press machine punches the workpiece to be processed, it often places the workpiece to be processed in the fixture, and then the punch continuously reciprocates up and down to punch the workpiece to be processed. Since most of the existing workbenches are fixed On the operation table, the work table cannot be tilted, so that when some irregular shaped workpieces are punched, because the end face of the workpiece to be punched is in an inclined state, the work table cannot adjust the end face of the workpiece to be punched to In the horizontal state, the punch cannot punch well the workpiece to be processed, resulting in low punching performance of the press.

After the processing end surface of the workpiece to be processed is adjusted to the horizontal position, the oil cylinder 3 works to drive the punch 4 to punch the processing end surface of the workpiece until the punching is completed.

In order to better demonstrate the working process of the high-performance adjustable inclination press, this embodiment proposes a working method of the high-performance adjustable inclination press, including the following steps:

Step 1: Adjust the distance between the first clamping part 71 and the second clamping part 72 according to the size of the workpiece to be processed, and then place the workpiece to be processed on the first clamping part 71 and the second clamping part 72, Make the first clamping part 71 and the second clamping part 72 clamp the workpiece to be processed, and fix the first clamping part 71 and the second clamping part 72 on the workbench 7 by bolts;

Step 2: After the workpiece to be processed is fixed, adjust the height between the level 95 and the workpiece to be processed by moving the first slider 92 on the guide rail 91, and adjust the level 95 and the workpiece to be processed by extending and contracting the connecting rod 93 at the same time The distance between until the level 95 is located above the workpiece to be processed and close to one end of the processed end face of the workpiece to be processed;

Step 3: After the position of the spirit level 95 is adjusted, the cylinder 83 works, and the extension rod of the cylinder 83 is elongated so that the support horizontal plate 84 moves away from the cylinder 83 under the guiding support of the first vertical guide plate 85 and the second vertical guide plate 86. Direction movement, support horizontal plate 84 moves towards the direction away from cylinder 83 and makes fixed block 87 also move towards the direction away from cylinder 83, and this moment, fixed block 87 rises, and fixed block 87 rises so that the end of workbench 7 near fixed block 87 also rises , the workbench 7 is tilted until the processing end face of the workpiece to be processed is in a horizontal position and contacts the level 95, after which the cylinder 83 no longer works.

Step 4: After the processing end surface of the workpiece to be processed is adjusted to a horizontal position, the oil cylinder 3 drives the punch 4 to punch the processing end surface of the workpiece until the punching is completed.

Operation process: adjust the distance between the first clamping part 71 and the second clamping part 72 according to the size of the workpiece to be processed, and then place the workpiece to be processed on the first clamping part 71 and the second clamping part 72, Make the first clamping part 71 and the second clamping part 72 clamp the workpiece to be processed, and fix the first clamping part 71 and the second clamping part 72 on the workbench 7 by bolts, after the workpiece to be processed is fixed, The height between the level 95 and the workpiece to be processed is adjusted by the first slide block 92 moving on the guide rail 91, and the distance between the level 95 and the workpiece to be processed is adjusted by the elongation and contraction of the connecting rod 93 until the level 95 is positioned at The top of the workpiece to be processed is close to one end of the processed end face of the workpiece to be processed. After the position of the level meter 95 is adjusted, the cylinder 83 works, and the extension rod of the cylinder 83 is elongated so that the support horizontal plate 84 is positioned between the first guide vertical plate 85 and the second guide vertical plate. Under the guide support action of vertical plate 86, move toward the direction away from cylinder 83, and support horizontal plate 84 moves toward the direction away from cylinder 83 so that fixed block 87 also moves toward the direction away from cylinder 83, and now fixed block 87 rises, and fixed block 87 moves toward the direction away from cylinder 83. The rise makes the end of the workbench 7 close to the fixed block 87 also rise. At this time, the workbench 7 is tilted until the processing end surface of the workpiece to be processed is in a horizontal position and contacts the level 95. After that, the cylinder 83 no longer works, and the processing end surface of the workpiece to be processed is adjusted. After reaching the horizontal position, the oil cylinder 3 works to drive the punch 4 to punch the end face of the workpiece to be processed until the punching is completed.

In summary, the high-performance adjustable inclination press and working method proposed by the present invention adjust the distance between the first clamping part 71 and the second clamping part 72 according to the size of the workpiece to be processed, and then The processed workpiece is placed on the first clamping part 71 and the second clamping part 72, so that the first clamping part 71 and the second clamping part 72 clamp the workpiece to be processed, and the first clamping part 71 and the second clamping part 72 are clamped by bolts.
