Abstract
A smooth trimming device for slab, is provided with B decompressor below A decompressor; A decompressor comprises patrix A, centre position, the bottom processing patrix stamping knife A of patrix A, and be provided with counterdie A immediately below patrix A, the centre position on counterdie A top is processed with counterdie stamping knife A; B decompressor comprises patrix B, and the centre position, bottom of patrix B is processed with patrix stamping knife B, is provided with counterdie B immediately below patrix B, and the centre position on counterdie B top is processed with counterdie stamping knife B; The position that the centre position of counterdie stamping knife B is corresponding with workpiece hole is provided with locating pin.First use A decompressor stamped workpieces once, carry out second time punching press by B decompressor to workpiece again, now the cutting output of stamping knife is very little, and the gap between patrix stamping knife B and counterdie stamping knife B can be transferred to very little, whole incisal bevel is euphotic belt, i.e. incisal bevel unusual light.Employing two times punch is shaping, changes gap between stamping knife simultaneously, makes incisal bevel become unusual light.
Description
Technical field
The utility model relates to trimming device technical field, particularly relates to a kind of smooth trimming device of slab.
Background technology
At present, during the domestic stamped workpieces at slab is produced, the cutting face of the workpiece after punching press is all more coarse, due to some particular/special requirement, must ensure the cutting face unusual light of workpiece.When the thickness of plate is greater than 10mm, if ensure cutting face unusual light, just must adopt high-precision punch press, the price of high accuracy punch press is very expensive, processing cost will be caused like this to improve, make product lack the market competitiveness, how to utilize common punch press to make the cutting face of workpiece become smooth and just seem extremely important.
Utility model content
For the weak point existed in the problems referred to above, the utility model provides a kind of smooth trimming device of slab.
For achieving the above object, the utility model provides a kind of smooth trimming device of slab, comprising: A decompressor, is provided with B decompressor below described A decompressor;
A decompressor comprises patrix A, centre position, the bottom processing patrix stamping knife A of described patrix A, and be provided with counterdie A immediately below described patrix A, the centre position on described counterdie A top is processed with counterdie stamping knife A;
B decompressor comprises patrix B, and the centre position, bottom of described patrix B is processed with patrix stamping knife B, is provided with counterdie B immediately below described patrix B, and the centre position on described counterdie B top is processed with counterdie stamping knife B;
The position that the centre position of described counterdie stamping knife B is corresponding with workpiece hole is provided with locating pin.
Preferred as the utility model, the monolateral gap of described patrix stamping knife A and described counterdie stamping knife A is 1-1.2mm.
Preferred as the utility model, the monolateral gap of described patrix stamping knife B and described counterdie stamping knife B is 0.04-0.06mm.
Improve further as the utility model, described counterdie stamping knife A and described counterdie stamping knife B is connected with described counterdie A and described counterdie B by bolt.
Improve further as the utility model, described locating pin is connected with described counterdie B by interference fit.
Improve further as the utility model, the top chamfering of described locating pin.
Compared with prior art, the present invention has the following advantages:
1, the present invention adopts the method for common punch press two times punch, makes the cutting face of workpiece become smooth, greatly cost-saving.
2, by regulating the monolateral gap of patrix stamping knife B and counterdie stamping knife B, make the cutting face euphotic belt of workpiece elongated, package power diminishes simultaneously.
3, adopt locating pin location, simple and reliable, the chamfering on locating pin top makes workpiece easily place.

Detailed description of the invention
As shown in figs. 1-7, the smooth trimming device of a kind of slab described in the utility model embodiment, comprising: A decompressor, is provided with B decompressor below described A decompressor; A decompressor comprises patrix A1, centre position, the bottom processing patrix stamping knife A2 of described patrix A1, and be provided with counterdie A3 immediately below described patrix A1, the centre position on described counterdie A3 top is processed with counterdie stamping knife A4; B decompressor comprises patrix B5, and the centre position, bottom of described patrix B5 is processed with patrix stamping knife B6, is provided with counterdie B7 immediately below described patrix B5, and the centre position on described counterdie B7 top is processed with counterdie stamping knife B8; The position that the centre position of described counterdie stamping knife B8 is corresponding with workpiece hole is provided with locating pin 9.The monolateral gap of described patrix stamping knife A2 and described counterdie stamping knife A4 is 1-1.2mm, the monolateral gap of described patrix stamping knife B6 and described counterdie stamping knife B8 is 0.04-0.06mm, described counterdie stamping knife A4 and described counterdie stamping knife B8 is connected with described counterdie A3 and described counterdie B7 by bolt, described locating pin 9 is connected with described counterdie B7 by interference fit, the top chamfering of described locating pin 9.Adopt the method for common punch press two times punch, make the cutting face of workpiece become smooth, greatly cost-saving.By regulating the monolateral gap of patrix stamping knife B and counterdie stamping knife B, make the cutting face euphotic belt of workpiece elongated, namely cutting face is smooth, package power diminishes simultaneously, and package power refers to the tension force between the cutting face of workpiece and stamping knife, and package power is large, light belt length, the demoulding of workpiece simultaneously becomes very difficult.Employing locating pin is located, and simple and reliable, the chamfering on locating pin top makes workpiece easily place.
During concrete use: first first time punching press, slab 10 is placed on the counterdie A of A decompressor, carry out punching press, make workpiece leave certain surplus simultaneously, monolateral surplus is 0.6-0.7mm, workpiece after first time punching press is put on B decompressor, two borehole jacks on workpiece are in locating pin, carry out second time punching press, because cutting output is now 0.6-0.7mm, so the monolateral gap of patrix stamping knife B6 and counterdie stamping knife B8 can be done very little, for 0.04-0.06mm, make the euphotic belt in the cutting face of workpiece elongated, package power is little simultaneously, is convenient in demoulding.Common punch press, by two times punch and the monolateral gap changing patrix stamping knife B6 and counterdie stamping knife B8, just can make the cutting face of workpiece become smooth.
The foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, for a person skilled in the art, the utility model can have various modifications and variations.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
