Abstract
The invention belongs to the technical field of punching, and relates to a punching die, in particular to a football-shaped cake die punching die. The cake die punching die comprises an upper die core and a lower die core. The upper die core is fixed to an upper die core base. The upper die core base is fixed to an upper base. The lower die core is fixed to a lower base. The upper die core is made of rubber materials and is smooth in surface. Due to the fact that the upper die core is made of rubber materials, the rubber materials submit to metal materials in the punching process, the upper die core will change according to the shape of the lower die core, in addition, the pressed rubber body has the rebound swelling characteristic, and the punched product quality is greatly improved; due to the fact that the upper die core made of the rubber materials has the compression characteristic, only the shape of a puncher pin needs to be made, no punching lines need to be machined, and the manufacturing cost of the upper die core is greatly saved; due to the fact that the upper die core made of the rubber materials has the compression characteristic, contraction distortion of the upper die core is matched with the lines of the lower die core, and the alignment matching time is saved.
Description
Technical field
The present invention relates to a kind of diel, a kind of cake die stamping mould of football-shaped, belongs to stamping technology field specifically.
Background technology
At present, the upper and lower die of diel is mostly harder metal material, instantly mould core structure more complicated, and on lower die wall with pressing direction not when unidirectional horizontal bar lines, upper cores and lower die punching press need to find lines aligned fit accurately, and in actual punching course, belong to " very stiff and demanding " antagonism, be often difficult to reach the effect wanted.
Summary of the invention
The object of the invention is to overcome above-mentioned weak point, thus a kind of cake die stamping mould is provided, the stamping quality of product can be improved, saved cost of manufacture.
According to technical scheme provided by the invention, cake die stamping mould comprises upper cores and lower die, lower die is positioned at immediately below upper cores, lower die surface is provided with punching press lines, it is characterized in that: upper cores is fixed on upper cores seat, upper cores seat is fixed on top base, and lower die is fixed on bottom base; Described upper cores adopts excellent power glue material to make, smooth surface.
Further, top base is provided with several backstays, and bottom base is provided with the locating hole identical with backstay quantity, each backstay and a locating hole corresponding matching.
Compared with the prior art the present invention has the following advantages:
Structure of the present invention is simple, compact, reasonable, and upper cores adopts excellent power glue material, in punching course, rubber yields to metal material, upper cores can according to the change in shape of lower die, and the excellent power glue of pressurized itself has bounce-back expansion characteristics in addition, and punching press product quality out improves greatly; Adopting the upper cores of excellent power glue material because of the characteristic of the pressurized contraction of itself, as long as make the shape of drift, without the need to processing punching press lines, greatly having saved the cost of manufacture of upper cores; Adopt the upper cores of excellent power glue material because of the characteristic of its pressurized contraction, coordinate the lines of lower die with the contraction distortion of self, save the time of finding cooperation accurately.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Description of reference numerals: die, 6-bottom base, 7-locating hole under 1-upper cores, 2-upper cores seat, 3-backstay, 4-top base, 5-.
Detailed description of the invention
Embodiment in is by reference to the accompanying drawings further described by the present invention below:
As shown in Figure 1, the present invention mainly comprises upper cores 1 and lower die 5, and lower die 5 is positioned at immediately below upper cores 1.Upper cores 1 is fixed on upper cores seat 2, and upper cores seat 2 is fixed on top base 4.Lower die 5 is fixed on bottom base 6.
Described upper cores 1 smooth surface, adopt excellent power glue material to make, hardness range is shore A10-D80.Described lower die 5 adopts material to make, and lower die adopts 5Cr12Mov cold working die steel material to make, and surface is provided with punching press lines.In punching course, die steel material yielded to by excellent power glue, and upper cores can according to the change in shape of lower die, and the excellent power glue of pressurized itself has bounce-back expansion characteristics in addition, and punching press product quality out improves greatly.
Described top base 4 is provided with several backstays 3, and bottom base 6 is provided with the locating hole 7 identical with backstay 3 quantity, each backstay 3 and locating hole 7 corresponding matching.During punching press, upper cores 1 downwards die 5 moves, and backstay 3 and locating hole 7 play guide-localization effect.
Upper cores of the present invention adopts excellent power glue material, and in punching course, metal material yielded to by excellent power glue, and upper cores can according to the change in shape of lower die, and the rubber of pressurized itself has bounce-back expansion characteristics in addition, and punching press product quality out improves greatly.Adopting the upper cores of excellent power glue material because of the characteristic of the pressurized contraction of itself, as long as make the shape of drift, without the need to processing punching press lines, greatly having saved the cost of manufacture of upper cores; Adopt the upper cores of excellent power glue material because of the characteristic of its pressurized contraction, coordinate the lines of lower die with the contraction distortion of self, save the time of finding cooperation accurately.
