Description

Technical Field

[0001] The utility model relates to the technical field of stamping accessories, in particular to a full tungsten steel punch structure for high-strength hole extrusion. Background Art

[0002] The punch is also called a punch, upper die, male die, punch needle, etc., and the punch is divided into A-type punch, T-type punch, and special-shaped punch. The punch is a metal part installed on the stamping die, which is used for direct contact with the material to deform and cut the material.

[0003] The punch is generally fixed directly on the punch rod by means of threads. Long-term use may easily lead to the loosening of the punch, resulting in a slight misalignment between the punch and the punch rod. Subsequently, when the punch is driven by the punch rod to punch, the processing position is inaccurate, resulting in an unsatisfactory stamping effect. The current method of fixing the punch is not ideal and has certain shortcomings, so it needs to be improved. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a high-strength all-tungsten steel punch structure for extruding holes. A connecting seat is arranged between the punch rod and the punch, and a connecting component is threadedly connected to the connecting seat. When the thread of the connecting component is rotated, it can cooperate with an auxiliary positioning mechanism to achieve double fixation and clamping of the punch, thereby ensuring the fixing effect of the punch and solving the problem that the current punch fixing method is not ideal and causes it to become loose easily.

[0005] In order to achieve the above-mentioned purpose, the utility model specifically adopts the following technical solutions:

[0006] A high-strength all-tungsten steel punch structure for extruding a hole, comprising a connecting seat, the connecting seat is fixed to the end of a punching rod, and a connecting component is threadedly connected to the connecting seat, and also comprises:

[0007] A punch component, wherein the punch component is adapted at the inner center of the connecting seat;

[0008] Auxiliary positioning mechanism, at least two auxiliary positioning mechanisms are provided, and the auxiliary positioning mechanisms are slidably connected to the corresponding track grooves of the connecting seat, and the connecting component rotates along the inner wall thread of the connecting seat and cooperates with the auxiliary positioning mechanism to realize the double fixation of the punch component.

[0009] Furthermore, the connecting component includes an annular cylinder threadedly connected to the inner wall of the connecting seat, and a hand-held handle integrally formed on one side of the annular cylinder, and an internal thread is provided on the inner wall of the annular cylinder.

[0010] Furthermore, the punch component includes a punch body, and a first fixing portion and a second fixing portion are provided on the punch body, wherein the first fixing portion is provided with an external thread, the external thread is adapted to the internal thread, and a protrusion is integrally formed on one side of the second fixing portion, and the protrusion is adapted to a groove opened in the connecting seat.

[0011] Furthermore, the auxiliary positioning mechanism includes a sliding block slidably connected to the track groove, and a positioning block fixedly connected to the sliding block, the positioning blocks cooperate with each other to achieve clamping of the second fixed part, and a second inclined groove is provided on one side of the positioning block, and the second inclined groove matches the first inclined groove provided on the annular cylinder.

[0012] Furthermore, a return spring is fixed between one side of the sliding block and the connecting seat.

[0013] Compared with the prior art, the utility model provides a high-strength all-tungsten steel punch structure for hole extrusion, which has the following beneficial effects:

[0014] The utility model fixes a connecting seat at the end of the punching rod, and threadably connects a connecting component to the connecting seat. The main part of the connecting component is an annular tube. When in use, the punch component is adapted to the inner side of the connecting seat. When the annular tube rotates, the initial fixation of the punch component can be achieved by means of a thread.

During the movement of the connecting component 4, the auxiliary positioning mechanism 6 can be driven to move to realize the secondary clamping of the punch component 5. This method can realize the effective fixation of the punch component 5 and avoid shaking during long-term use.

[0025] like Figure 1 and Figure 2 As shown, in some embodiments, the connecting component 4 includes an annular cylinder 401 threadedly connected to the inner wall of the connecting seat 2, and a hand handle 403 integrally formed on one side of the annular cylinder 401.
