A kind of for the high accuracy guide modular construction in die cutting die
The utility model relates to a kind of die cutting die, specifically a kind of for the high accuracy guide modular construction in die cutting die.
The total production cost of punching parts is generally by a lot of expenditure pattern (cost of raw and processed materials+each operation processing charges+labour cost+administrative expenses+other correlative charges), wherein cost of raw and processed materials accounts for significant proportion, in order to improve utilization rate of raw materials, usually need to optimize the structure of diel, step pitch, expect wide on accomplish rational design.In market competition, the production cost of enterprise is lower, and relative competitive is larger, and the profit that enterprise can bring the cost reduced simultaneously drops in technical research and the production automation.
As shown in Figure 1, be the structural representation of existing continuous cutting mould.This die cutting die is formed primarily of cope match-plate pattern 1, lower bolster 2, abnormal-shaped punch 3, die 4, cut-out drift 5, guide assembly 6.General continuous punching casting die technology for blanking: coil of strip material (panel beating raw material) is flattened by feeder, then produce qualified blank part through each operation punching of mould, trimming etc.Because the structure precision of the guide assembly 6 of mould is not high, once raw material have change width, size can not be regulated, affect Product Precision, so abnormal-shaped punch 3 pairs of raw material can only be increased in a mold carry out trimming place, but can not shear constitution be used at the cut-off part edge of a knife, this generates waste material.
Because part material strip will can produce a large amount of waste materials by multiple operation such as punching, trimming, this just greatly reduces raw-material utilization rate, and waste of raw materials is comparatively large, causes manufactured parts profit to reduce, and cost is and then increase also.
Summary of the invention
The purpose of this utility model is exactly for the problem in background technology, provides a kind ofly by the improvement to guide modular construction, can improve the precision of die cutting die for the high accuracy guide modular construction in die cutting die, reduces waste material, thus reduces cost.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of for the high accuracy guide modular construction in die cutting die, it is fixed on the lower bolster of mould, it is characterized in that, this guide modular construction comprises handle fixing base, handle, lower shoe, guide holder, positioning insert, power transmission shaft, transmission insert, transmission holder, guide pad, platter and marking chi; Described handle is connected with power transmission shaft, and described power transmission shaft is fixed on transmission holder; Described marking chi is located in handle fixing base, and described handle fixing base is connected with transmission holder; Described power transmission shaft is fixed by transmission insert and described positioning insert; Described lower shoe is established guide holder, described guide holder is connected with described guide pad by positioning insert; Described guide pad is fixed on described platter.
Preferred: described handle is provided with cover cap.
Preferred: described handle fixing base is connected by screw or pin with transmission holder.
Preferred: described guide holder is fixed on described lower shoe by screw or pin.
Preferred: described guide pad is fixed on described platter by screw or pin.
The beneficial effects of the utility model are: this guide modular construction is compared with existing guide assembly, handle portion has been set up in its structure, by regulating handle thus adjustment guide pad absorb raw material width tolerance variation, can effectively avoid raw material in process of production, easily because of step pitch with material is wide affects the not in place and a large amount of waste materials that produce of size, improve raw-material utilization rate; According to marking chi Measurement accuracy thus regulate raw-material width dimensions by handle, trimming precision can be improved, reduce waste material, thus reduce cost.
Structure of the present utility model is fixed on the lower bolster of mould, material strip can be made die-cut stable in a mold, make die-cut parts size precision higher; Make the structural design of mould more reasonable; Its structure is simple, and convenient operation is practical.

Detailed description of the invention
Below in conjunction with accompanying drawing and preferred scheme, detailed description of the invention of the present utility model is described in further detail.
By reference to the accompanying drawings 2 and accompanying drawing 3 structure chart of the present utility model is described, specifically a kind of composition structural representation for the high accuracy guide modular construction in die cutting die.As shown in Figure 3, guide modular construction of the present utility model is fixed on the lower bolster 2 of mould by feet.As shown in Figure 2, this guide modular construction comprises handle fixing base 11, handle 12, lower shoe 13, guide holder 14, positioning insert 15, power transmission shaft 21, transmission insert 16, transmission holder 17, guide pad 18, platter 19 and marking chi 20; Described handle 12 is connected with power transmission shaft 21, and described power transmission shaft 21 is fixed on transmission holder 17; Described marking chi 20 is located in handle fixing base 11, and described handle fixing base 11 is connected with transmission holder 17; Described power transmission shaft 21 is fixed by transmission insert 16 and described positioning insert 15; Described lower shoe 13 establishes guide holder 14, and described guide holder 14 is connected with described guide pad 18 by positioning insert 15; Described guide pad 18 is fixed on described platter 19.
Embodiment: the handle 12 in the present embodiment is provided with cover cap 22, cover cap 22 can play the effect of protection handle 12.Handle fixing base 11 in the present embodiment is connected by screw with transmission holder 17; Described guide holder 14 is fixed by a pin on described lower shoe 13; Described guide pad 18 is screwed on described platter 19.
Operation principle: first assemble guide modular construction 100 according to correct step, is fixed on the lower bolster 2 of mould by the guide modular construction 100 of entirety by screw or pin, can arranges feet 101 between lower bolster 2 and guide modular construction 100; Then part material strip is sent in mould by the feeder of punch press material, the every stroke of punch press once, material strip marches forward a step pitch (mould guiding locate), material strip measures width through marking chi 20, regulate guide pad 18 according to measured value by handle 12, utilize guide pad 18 to absorb raw material tolerance; The last operations such as punching, incised notch mouth, cut-out of carrying out again complete punching parts production.
The utility model is connected on punch press by locked mode screw rod, and material strip often send once, and punching and edge-cutting once, by material along opening wide profile trimming, realizes high accuracy no waste mine die-cut.
