Description

Technical Field

[0001] The utility model relates to the technical field of punching machines, in particular to a punching component used for a metal gasket punching machine. Background Art

[0002] During equipment manufacturing, equipment assembly, and equipment maintenance, adjustments such as horizontality, verticality, height, and clearance are often involved. At this time, various gaskets of different thicknesses are needed for adjustment, especially for flange connections, which not only require gaskets but also require holes to be punched in the gaskets.

[0003] However, when the punching machine is processing the workpiece, the punching head of the punching machine will slip on the workpiece if the workpiece has no supporting force, and the workpiece after punching will be stuck on the punching head. After the punching head is raised, the staff needs to remove the workpiece from the punching head, so that the staff must fix the workpiece and drill holes, which will increase the labor intensity of the staff and reduce the working efficiency of the punching machine.

[0004] To this end, we propose a punching assembly for a metal gasket punching machine. Utility Model Content

[0005] The utility model aims to provide a punching assembly for a metal gasket punching machine to solve the problems raised in the above background technology.

[0007] Optionally, the top of the downward pressure spring is in tight contact with the top of the interior of the telescopic sleeve, and the bottom of the downward pressure spring is in tight contact with the top of the sliding cylinder.

[0008] Optionally, the clamping ring, the fixed top plate and the punching rod are coaxially arranged, and the fixed top plate is located above the mounting seat.

[0009] Optionally, a linear sleeve is provided in the middle of the support frame, and the punching rod is slidably connected to the middle of the linear sleeve.

[0010] Optionally, a piston plate located inside the linear sleeve is fixedly mounted on the middle portion of the punching rod, and a lifting spring is arranged inside the linear sleeve.

[0011] Optionally, the lifting spring sleeve is arranged on the outside of the punching rod, the top of the lifting spring is in tight contact with the bottom of the piston plate, and the bottom of the lifting spring is in tight contact with the bottom of the linear sleeve.

[0012] Optionally, the downward pressure cylinder is an adjustable cylinder, and the downward pressure cylinder is provided with a stroke adjustment device.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The punching assembly for the metal gasket punching machine is provided with a clamping assembly. After the workpiece with holes is placed under the punching head, as the downward pressure cylinder pushes the punching rod downward, the clamping ring of the clamping assembly moves downward to clamp the workpiece. As the punching rod continues to move downward, the telescopic rod contracts toward the inside of the telescopic sleeve, so that the punching head punches holes in the workpiece. After the punching is completed, the downward pressure cylinder pulls the punching rod upward. Under the action of the downward pressure spring, the clamping ring always clamps the workpiece to prevent the workpiece from being stuck on the outside of the punching head, so that the workpiece after the holes are punched can be quickly removed from the processing table, which reduces the labor intensity of the staff and improves the working efficiency of the punching machine.

[0015] 2. The punching assembly for the metal gasket punching machine is provided with a linear sliding sleeve. When the pressing cylinder moves downward to drive the punching rod to press downward, the piston plate moves downward to squeeze the lifting spring, so that the lifting spring contracts. When the pressing cylinder contracts upward to drive the punching rod to move upward, the piston plate moves up, and the lifting spring pushes the piston plate. When the pressing cylinder stops working, the punching rod drives the punching head to move up, thereby ensuring the safe use of the equipment. BRIEF DESCRIPTION OF THE DRAWINGS

By setting a clamping assembly 7, after the workpiece with holes is placed under the punching head 6, as the downward pressure cylinder 2 pushes the punching rod 3 to move downward, the clamping ring 76 of the clamping assembly 7 moves downward to clamp the workpiece. As the punching rod 3 continues to move downward, the telescopic rod 74 contracts toward the inside of the telescopic sleeve 72, so that the punching head punches holes in the workpiece. After the punching is completed, the downward pressure cylinder 2 pulls the punching rod 3 upward. Under the action of the downward pressure spring 75, the clamping ring 76 always presses the workpiece to prevent the workpiece from being stuck on the outside of the punching head 6, so that the workpiece after punching can be quickly removed from the processing table, which reduces the labor intensity of the staff and improves the working efficiency of the punching machine.

[0022] The top of the downward pressure spring 75 is in close contact with the top of the telescopic sleeve 72, and the bottom of the downward pressure spring 75 is in close contact with the top of the sliding cylinder 73. The clamping ring 76, the fixed top plate 71 and the punching rod 3 are coaxially arranged, and the fixed top plate 71 is located above the mounting seat 5.

[0023] A linear sleeve 4 is provided in the middle of the support frame 1, and the stamping rod 3 is slidably connected with the middle part of the linear sleeve 4.

By setting the linear sleeve 4, when the pressing cylinder 2 moves downward to drive the stamping rod 3 to press downward, the piston plate 8 moves downward to squeeze the lifting spring 9, so that the lifting spring 9 contracts. When the pressing cylinder 2 contracts upward to drive the stamping rod 3 to move upward, the piston plate 8 moves upward, and the lifting spring 9 pushes the piston plate 8, so that when the pressing cylinder 2 stops working, the stamping rod 3 drives the punching head 6 to move upward, ensuring the safe use of the equipment.

[0024] Working principle:

[0025] After the workpiece with holes to be punched is placed under the punching head 6, as the downward pressure cylinder 2 pushes the punching rod 3 to move downward, the clamping ring 76 of the clamping assembly 7 moves downward to clamp the workpiece. As the punching rod 3 continues to move downward, the telescopic rod 74 contracts toward the inside of the telescopic sleeve 72, so that the punching head punches holes in the workpiece. After the punching is completed, the downward pressure cylinder 2 pulls the punching rod 3 to move upward. Under the action of the downward pressure spring 75, the clamping ring 76 always presses the workpiece to prevent the workpiece from being stuck on the outside of the punching head 6, so that the workpiece can be quickly removed after the hole is punched. It can be quickly removed from the processing table, which reduces the labor intensity of the staff, thereby improving the working efficiency of the punching machine, and by setting a linear sleeve 4, when the pressing cylinder 2 moves downward to drive the punching rod 3 to press downward, the piston plate 8 moves downward to squeeze the lifting spring 9, so that the lifting spring 9 contracts. When the pressing cylinder 2 contracts upward to drive the punching rod 3 to move upward, the piston plate 8 moves upward, and the lifting spring 9 pushes the piston plate 8, so that when the pressing cylinder 2 stops working, the punching rod 3 drives the punching head 6 to move upward, thereby ensuring the safe use of the equipment.
