Abstract

The utility model discloses a step mould which comprises an upper mould and a lower mould. The upper mould is provided with an upper sub-mould, the lower mould is provided with a lower sub-mould, an upper backing plate is arranged between the upper sub-mould and the upper mould, and a lower backing plate is arranged between the lower sub-mould and the lower mould. Since the upper mould and the lower mould are provided with the upper sub-mould and the lower sub-mould respectively, stamping parts different in thickness and bending angle can be conveniently formed and processed on a bending machine by additionally arranging the backing plates different in thickness and changing the gap between the upper sub-mould and the lower sub-mould, and processing size is stable and processing efficiency is high.

Description

A kind of section differential mode tool

Technical field

The utility model relates to field of machining, particularly a kind of section differential mode tool.

Background technology

Numerous parts is a sheet metal component in the machinery industry; It is the plastic deformation that causes material through bending to sheet material; And then the shape that changes material is shaped; Accomplish but complicated parts often will cooperate through the Bending Mould of a plurality of operations to be shaped, bending equipment commonly used is numerical control bender, punch press, hydraulic press etc.Fig. 2 is a kind of sheet metal component 21, and it forms through sheet material shown in Figure 1 11 is carried out bending, but the shaping of this structure sheet metal component 21 is difficult to accomplish with general NC bending cutter.

The utility model content

For solving the problems of the technologies described above, the utility model provides a kind of section differential mode tool, with the quick shaping that realizes special sheet metal component and guarantee precision.

For achieving the above object, the technical scheme of the utility model is following:

A kind of section differential mode tool comprises upper die and lower die, and said patrix is provided with submodule, and said counterdie is provided with down submodule; Said going up between submodule and the patrix is provided with upper padding plate, is provided with lower bolster between said submodule down and the counterdie.

Preferably, the said submodule that goes up is fastened in the groove of said patrix, and the height of said upward submodule is consistent with the depth of groove of said patrix.

Preferably, said upper padding plate is positioned at the bottom portion of groove of said patrix.

Preferably, said submodule down is fastened in the groove of said counterdie, and the height of said submodule down is consistent with the depth of groove of said counterdie.

Preferably, said lower bolster is positioned at the bottom portion of groove of said counterdie.

Pass through technique scheme; The section differential mode tool that the utility model provides; It is through being provided with submodule and following submodule respectively in patrix and counterdie; And the backing plate through setting up different-thickness and changing goes up the gap between submodule and the following submodule, can realize easily on bender that the shaping of different-thickness and bending angle sheet metal component is processed, and processing dimension stablized, efficient is high.

35. submodule on 36. times submodules 37. of backstop

The specific embodiment

To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment will be carried out clear, intactly description.

According to Fig. 3, the section differential mode tool that the utility model provides comprises patrix 31 and counterdie 34; Patrix 31 is provided with the last submodule 37 in the groove that is fastened on patrix 31, and the height of last submodule 37 is consistent with the depth of groove of patrix 31; Counterdie 34 is provided with the following submodule 36 in the groove that is fastened on counterdie 34, and the height of following submodule 36 is consistent with the depth of groove of counterdie 34; Be provided with the upper padding plate 32 of the bottom portion of groove that is positioned at patrix 31 between last submodule 37 and the patrix 31, be provided with the lower bolster 33 of the bottom portion of groove that is positioned at counterdie 34 between following submodule 36 and the counterdie 34.

So that sheet material 11 shown in Figure 1 is processed into sheet metal component 21 shown in Figure 2 is example; The operation principle of the utility model is: upper padding plate 32 and the lower bolster 33 of selecting same thickness according to the height of 21 bendings of sheet metal component among Fig. 2; And respectively upper padding plate 32 and lower bolster 33 are packed in the mould by position shown in Figure 3; Patrix 31 and the counterdie 34 that to put backing plate again well install on the numerical control bender; Adjust gap between submodule 37 and the following submodule 36 with control bending angle, then sheet material 11 shown in Figure 1 is packed in the mould by position shown in Figure 3, guarantee that simultaneously an end of sheet material 11 leans against on the rear block 35 of the bender of adjusting the position; Wait to adjust and to start bender behind the gap between patrix 31 and the counterdie 34 and carry out bending, and obtain the sheet metal component 21 with certain bending thickness and bending angle shown in Figure 2.

The section differential mode tool that the utility model provides; It is through being provided with submodule 37 and following submodule 36 respectively in patrix 31 and counterdie 34; And the backing plate through setting up different-thickness and change the gap of going up between submodule 37 and the following submodule 36; Can on bender, realize the shaping processing of different-thickness and bending angle sheet metal component easily, and processing dimension is stable, efficient is high.

To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the utility model.Multiple modification to these embodiment will be conspicuous concerning those skilled in the art, and defined General Principle can realize under the situation of spirit that does not break away from the utility model or scope in other embodiments among this paper.Therefore, the utility model will can not be restricted to these embodiment shown in this paper, but will meet and principle disclosed herein and features of novelty the wideest corresponding to scope.
