fig. 2 is a perspective view of the embodiment shown in fig. 1.

Detailed Description

The present invention will be described in detail below with reference to embodiments shown in the drawings. The embodiments are not intended to limit the present invention, and structural, methodological, or functional changes made by those skilled in the art according to the embodiments are included in the scope of the present invention.

As shown in fig. 1, one embodiment of the stamping die disclosed in the present invention is that the die comprises an upper die 4 (the upper die may comprise an upper die fixing base and an upper die body provided on the upper die fixing base, in which case the stamping head is formed on the upper die body, the upper die body may be formed by welding, bolting/screwing or by engaging a groove provided on the upper die fixing base with the upper die body engaged in a groove, etc.), a lower die 2 (the lower die may comprise a lower die fixing base and a lower die body provided on the lower die fixing base, in which case the stamping hole is formed on the lower die body, the lower die body may be formed by welding, bolting/screwing or by engaging a groove provided on the lower die fixing base with the lower die body engaged in a groove, etc.), the upper die 4 has the stamping head, and the lower die 2 has the stamping, the workpiece is placed between the upper die 4 and the lower die 2 during stamping and forms a stamping structure, such as a hole structure and the like, on the workpiece through the matching of the stamping heads and the punching holes in the stamping process, wherein the stamping heads and the punching holes can be in an array arrangement structure as shown in the figure or in other scattering forms, in consideration of the impact and influence of the die on the surface of the workpiece in the stamping process, the scheme also considers the buffer cushion 5 arranged between the upper die 4 and the lower die 2, in addition, the buffer cushion 5 is also provided with a vacancy structure matched with the stamping heads, the vacancy structure penetrates through the buffer cushion 5 in the stamping stroke direction, the stamping heads, the vacancy structure and the punching holes are all arranged along the stamping stroke, so that the stamping heads move along the stamping stroke in the stamping process (the buffer cushion can be arranged on the upper die so as to move along with the upper die in the stamping process, and can also, thereby place the work piece on the lower mould and limit blotter, work piece to the lower mould again to satisfy the requirement of stamping process), through the vacancy structure and with punch a hole the cooperation and stamp the work piece and obtain suitable punching press work piece. The vacant structure can be a hole structure, so that the stroke requirement of the punching head is met.

In the above scheme, in order to facilitate cleaning of the blanking, a blanking area is further disposed on the lower die 2 corresponding to an area where the punched hole is located, and the punched hole penetrates through the lower die 2 in the blanking area. Therefore, in the stamping process, the blanking of the stamping stroke is separated from the blanking area directly through the punching after the workpiece is separated, so that the die is convenient to clean in work, and the working efficiency is improved. Further, in order to collect the blanking, the stamping die is further provided with a blanking recovery structure corresponding to the blanking area, and the blanking recovery structure comprises a cavity for recovering the blanking separated by the punching. Further preferably, the blanking recovery structure is a recovery basket, and an upper opening of the recovery basket faces the lower die 2 and is disposed corresponding to the blanking area. Further, a recovery basket is connected to the lower die 2 and is located below the blanking zone. Furthermore, the lower die 2 is provided with a hook, and the recovery basket further comprises a hanging rope connected to the hook.

In the scheme, the upper die 4 further comprises an upper die base 3, the lower die 2 further comprises a lower die base 1, the upper die base 3 is provided with a stroke rail I, the lower die base 1 is provided with a stroke rail II, and the stroke rail I and the stroke rail II are movably matched in the stamping stroke direction, so that in the stamping process, the realization of the stamping stroke is limited by the matching between the stroke rail I and the stroke rail II. Further, this limitation can be achieved by a sliding fit between an extension structure in which the stroke rail i is an extension structure that protrudes and extends from the upper die 4 toward the lower die 2, and a recess structure in which the stroke rail ii is recessed in the direction of the stroke of the press, the extension structure being movably fitted into the recess structure. Furthermore, a spring structure is further arranged in the concave structure, and the extension structure is movably matched with the concave structure and supported on the spring structure, so that the upper die 4 is reset through the elasticity of the spring structure in the stamping stroke, the operation action is reduced, and the efficiency is obviously improved.

As shown in fig. 1 and 2, the stamping die includes an upper die 4 disposed on an upper die base 3, the upper die 4 has a stamping head for stamping, and cuts a workpiece during stamping, and a lower die 2 disposed on a lower die base 1, the lower die 2 has a punching hole matched with the stamping head, the punching hole is an action end point of the stamping head during the whole stamping stroke, and stamping of the workpiece is realized through the process of the stroke. In addition, a buffer pad 5 is cooperatively disposed between the upper die 4 and the lower die 2, and is located between the workpiece and the upper die 4 to form a buffer function during the stamping process. In order to limit the operation of the upper die 4 and the lower die 2, a stroke rail i and a stroke rail ii are further provided for limiting the operation, wherein the stroke rail i can be a guide pillar 21, the stroke rail ii can be a guide groove 22, and the two are slidably matched with each other, and the guide pillar 21 slides in the guide groove 22 correspondingly during the whole stamping stroke. Still further, in order to obtain the return function, an elastic member for return, such as a spring, etc., may be provided in the guide groove 22, and the guide post 21 is supported to the spring, so that the guide post 21 applies an elastic pressure to the spring during the punching stroke, and the elastic return of the upper mold 4 is achieved by the restoring force of the spring at the end of the stroke, thus repeatedly improving the punching efficiency.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.

Furthermore, it should be understood that although the present description refers to embodiments, not every embodiment may contain only a single embodiment, and such description is for clarity only, and those skilled in the art should integrate the description, and the embodiments may be combined as appropriate to form other embodiments understood by those skilled in the art.
