Description

Technical Field

[0001] The utility model relates to aluminum alloy profile processing technology, in particular to an aluminum alloy profile punching component. Background Art

[0002] In order to meet the punching needs of holes of different sizes on aluminum alloy profiles, multiple sets of punching components (each set of punching components consists of a punch and a punch seat) are currently required, which is inconvenient to replace and there is a waste of resources. Utility Model Content

[0003] In order to solve the above problems, the utility model proposes an aluminum alloy profile punching assembly, which is composed of multiple punches and a punch seat. Each punch corresponds to a hole of different specifications and sizes, but the connecting parts are the same and can be installed on the same punch seat. When changing the size, only the punch needs to be disassembled and installed, and there is no need to disassemble the punch seat, which is convenient for replacement.

[0004] The technical solution of this utility model:

[0005] A punching assembly for an aluminum alloy profile comprises a punch seat and a punch. The punch seat is mounted on a punch press and has a groove at its bottom. The punch is mounted on the punch seat and has an upper end which is a connecting portion that matches the groove at the bottom of the punch seat and is inserted into the groove at the bottom of the punch seat. There are a number of punches, and the upper ends of the punches, i.e., the connecting portions, are the same.

[0006] The punch seat is provided with an exhaust hole, which is connected to the groove at the bottom of the punch seat, and the connecting part is located at the bottom of the groove at the bottom of the punch seat, so that the punch connecting part can be smoothly inserted into the groove at the bottom of the punch seat.

[0007] The punch seat is provided with a locking structure, through which the punch is locked;

[0008] The locking structure is a screw rod, which penetrates into the punch seat and is threadedly connected to the punch seat. The end of the screw rod extends into the groove at the bottom of the punch seat and abuts against the side wall of the punch connection part to lock the punch.

[0009] The screw rod is provided with an anti-loosening structure;

[0010] The anti-loosening structure includes a steel ball, a spring, and a pressure block. The screw head is provided with an axial through hole. The steel ball, spring, and pressure block are sequentially arranged in the axial through hole. The pressure block is connected to the screw. The spring applies elastic force to the steel ball so that the steel ball partially extends out of the axial through hole.

[0011] When the screw locks the punch, the steel ball rests on the punch seat;

[0012] The reaction force applied to the screw can effectively prevent the bolt from loosening;

[0013] The anti-loosening structure also includes a steel ball seat, which is arranged in the axial through hole and between the steel ball and the spring, and is provided with an arc groove. The steel ball is located in the arc groove on the steel ball seat; the two ends of the spring are respectively against the steel ball seat and the pressure block.

[0014] The pressure block is connected to the screw rod through an adjusting bolt, and the spring pressure can be adjusted.

[0015] The opening of the axial through hole for accommodating the steel ball to protrude is a constricted opening. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] like Figure 1-3 As shown, an aluminum alloy profile punching assembly comprises a punch seat 1, a punch A 2, and a punch B. The punch seat is installed on a punch press, and a groove is provided at the bottom thereof. The punch A or the punch B is installed on the punch seat, and the upper end thereof is a connecting portion, which matches with the groove at the bottom of the punch seat 1 and is inserted into the groove at the bottom of the punch seat 1; the upper ends of the punch A and the punch B, i.e., the connecting portions, are the same;

[0021] The punch seat 1 is provided with an exhaust hole 3, the exhaust hole 3 is connected to the groove at the bottom of the punch seat 1, and the connecting part is located at the bottom of the groove at the bottom of the punch seat 1;

[0022] The punch seat 1 is provided with a locking structure, through which the punch A 2 or the punch B 3 is locked;

[0023] The locking structure is a screw rod 4, which penetrates into the punch seat 1 and is threadedly connected to the punch seat 1. The end of the screw rod 4 extends into the groove at the bottom of the punch seat 1 and abuts against the side wall of the connecting part of the punch A2 or the punch B3 to lock the punch A2 or the punch B3.

[0024] The screw rod 4 is provided with an anti-loosening structure;

[0025] The anti-loosening structure includes a steel ball 5, a spring 6, and a pressure block 7. The head of the screw 4 is provided with an axial through hole. The steel ball 5, the spring 6, and the pressure block 7 are sequentially arranged in the axial through hole. The pressure block 7 is connected to the screw 4. The spring 6 applies elastic force to the steel ball 5 so that the steel ball 5 partially extends out of the axial through hole.

[0026] When the screw rod 4 locks the punch A 2 or the punch B 3, the steel ball 5 abuts against the punch seat 1;

[0027] The anti-loosening structure also includes a steel ball seat 8, which is arranged in the axial through hole and between the steel ball 5 and the spring 6, and is provided with an arc groove, and the steel ball 5 is located in the arc groove on the steel ball seat 8; the two ends of the spring 6 are respectively against the steel ball seat 8 and the pressure block 7;

[0028] The pressing block 7 is connected to the screw rod 4 via an adjusting bolt 9;

[0029] The opening of the axial through hole for accommodating the steel ball 5 to protrude is a constricted opening.
