Description

Technical Field

[0001] This utility model relates to the technical field of lobster tail cutting equipment, and in particular to a punching mechanism for a lobster tail cutting machine. Background Technology

[0002] A lobster buckle is a decorative item named for its resemblance to a curled-up lobster. Lobster buckles are very common in daily life and have a wide range of uses. They come in various shapes and types and are generally made of various metals. Colors include silver, gold, and black, and these colors can be combined with other accessories in different ways.

[0003] The lobster buckle mainly consists of three parts: the buckle body, a trigger, and a torsion spring. To connect the lobster buckle to the connecting ring (a connecting ring is provided between the lobster buckle and the figure-eight buckle), a through hole is provided at the tail end of the lobster buckle body. In existing technology, the through hole can be formed by directly winding a wire around it, or by forming it through mold assembly. The former method lacks structural strength and is generally not used, while the latter creates a tail strip at the tail end of the lobster buckle body, which needs to be cut off. Currently, the tail strip is usually cut after the lobster buckle body is formed, and it is primarily done manually. Because the connection between the tail strip and the lobster buckle is quite strong, this method is time-consuming and labor-intensive, with low cutting accuracy and a high defect rate. Furthermore, even when using equipment to cut the tail strip, the lobster buckle body needs to be placed in a fixed position before using a cutter, making high-speed cutting impossible and resulting in low efficiency. Currently, there is no technical solution for accurately cutting the tail strip, and improvements are needed to achieve faster and more precise tail strip removal. Utility Model Content

[0004] To solve the above problems, this utility model proposes a punching mechanism for a lobster tail-cutting machine.

[0005] The technical solution adopted in this utility model is: a punching mechanism for a lobster tail-cutting machine, used to cut the tail strip of the lobster tail body in conjunction with a tooling mold base, the punching mechanism comprising:

[0006] Base;

[0007] A slide rail frame is fixed on the base. The slide rail frame is provided with a first slide groove arranged vertically and a second slide groove arranged horizontally. A first slide bar is slidably installed in the first slide groove. The upper end of the first slide bar is provided with an obliquely arranged guide block.

[0008] The second slide bar is slidably installed in the second slide groove. The second slide bar is provided with a guide groove for the guide block to slide into. The extension direction of the guide groove is consistent with the extension direction of the guide block.

[0009] A driving device is installed on one side of the first slide bar and is used to drive the first slide bar to move back and forth along the first slide groove.

[0010] A punch, fixed on the second slide bar, is used to punch the lobster buckle body located on the tooling mold base.

[0011] Several alternative methods are provided below, but they are not intended as additional limitations on the overall solution above. They are merely further additions or optimizations. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution above, or multiple alternative methods can be combined with each other.

[0012] Preferably, the punch extends along the extension direction of the second groove.

[0013] Preferably, one end of the punch extends into the second slide bar, and the end of the punch is provided with a limiting block, and the second slide bar is provided with a notch for the limiting block to engage.

[0014] Preferably, the first slide bar has a preparatory state and a stamping state. In the preparatory state, one side of the guide block abuts against the inner wall of the guide groove. In the stamping state, the upper end of the guide block abuts against the lower part of the inner wall of the guide groove, or abuts against the inner wall of the first slide groove.

[0015] Preferably, the upper end of the slide rail frame is provided with a clearance opening. In the ready state, the upper end of the guide block extends into the clearance opening and abuts against one side of the clearance opening.

[0016] Preferably, the lobster tail-cutting machine includes a frame, a working panel on the frame, a base fixed above the working panel, and a driving device comprising:

[0017] Drive motor;

[0018] The drive spindle is fixed on the frame.

[0019] An active sprocket is mounted on the drive spindle and is linked to the drive motor via a chain;

[0020] The cam is fixed on the drive spindle;

[0021] A pull rod has a roller at one end and is fixed to the first slide bar at the other end. The roller is mounted on the cam, and the working panel has a through-hole for the pull rod to pass through.

[0022] Preferably, a guide sleeve is fixed below the working panel, and the pull rod passes through the guide sleeve.

[0023] Preferably, the drive spindle is provided with at least one bushing, the bushing is provided with at least one support column, the support column is fixed below the working panel, and one end of the drive spindle is provided with a handwheel.

[0026] Compared with the prior art, this utility model has the following beneficial effects:

[0027] This utility model has a stable structure and occupies little space. The base is fixed on the working panel, and the slide rail is fixed on the base. The driving device drives the first slide bar to move up and down along the first slide groove. Since the guide block and the guide groove are both arranged obliquely, when the first slide bar moves down, the guide block will squeeze the front side of the guide groove, thereby driving the second slide bar to move forward along the second slide groove, and causing the punch fixed on the second slide bar to cut the lobster buckle body located on the tooling mold base. When the first slide bar moves up, the guide block will squeeze the rear side of the guide groove, thereby driving the second slide bar and the punch to return to their original position. The overall action is simple and adopts a mechanical drive method, with a long service life, which can meet the requirements of high-speed and precise cutting of the tail strip on the lobster buckle body.
