Description

The bar fine shearing mould
Technical field
The present invention relates to a kind of bar fine shearing mould, it belongs to the bar accurate shearing mould that uses on a kind of UP machine.
Background technology
At present in field of machining, the mode that the blanking of bar still adopts forcing press to shear is though this method has blanking efficient height, advantage that material wastage rate is low.But can not adopt mould during owing to its shearing blanking, thereby use this forcing press can't improve the cross section quality of finish forge blank, reduce to cut off distortion.Therefore, there is that the blanking semifinished product precision is low, the many shortcomings of section defective of the cross section quality difference of blank and cut-out.
Summary of the invention
The technological difficulties that the objective of the invention is to solve that existing forcing press shears that the blanking semifinished product precision that bar exists is low, the section defective of the cross section quality difference of blank and cut-out are many and a kind of blanking efficient height is provided, cross section quality is good, the section defective is few and the bar fine shearing mould that can directly use on forcing press.
Task of the present invention is achieved in that bar fine shearing mould that energy uses of design on ordinary press, this bar fine shearing mould, and it comprises lower bolster, is located at the following tool fixing frame on lower bolster right side, is located at down the bottom knife of one jiao of tool fixing frame; Cope match-plate pattern, be located at the last tool fixing frame in cope match-plate pattern left side, be located at the cutter of one jiao of tool fixing frame, wherein: the lower fixture that it also comprises by upper clamping block, go up fastening spring, go up last clamping device that connecting bolt and last fixed block constitute and be made of clamp, following fastening spring, following connecting bolt and following fixed block down; Upper clamping block is associated in last fixed block by last connecting bolt, and last fastening spring is located between upper clamping block and the last fixed block, and last clamping device is located at the right side of cope match-plate pattern; Following clamp is associated in following fixed block by following connecting bolt, and following fastening spring is located at down between clamp and the following fixed block, and lower fixture is located at the left side of lower bolster; Last clamping device and lower fixture are located on the same mould and motion with cutter and bottom knife, and along with the increase of cutter and bottom knife cutting stroke, the radially clamping force of last clamping device and lower fixture increases thereupon.
Because the structure of required radially clamping force that the present invention has adopted spring to provide when shearing bar, and the mechanism and the shearing tool of this radially clamping force be located on the same mould, so compare, have following advantage with background technology:
1, radially the mechanism and the shearing tool of clamping force are located on the same mould, have saved special clamping device, and the present invention can be used on punching machine or friction press, saved production cost, have improved blanking efficient.
2, because with radially the mechanism and the shearing tool of clamping force are located on the same mould, and the mechanism of the radially clamping force of patrix is corresponding with the shearing tool of counterdie, the mechanism of the radially clamping force of counterdie is corresponding with the shearing tool of patrix, when shearing bar, under the effect of clamping force mechanism radially, the detrusion of bar is reduced, improved cross section quality, reduce and resolve planar defect.
Description of drawings
Accompanying drawing is a structural representation of the present invention.
The specific embodiment
As shown in drawings, the bar fine shearing mould in the present embodiment, it comprises lower bolster 1, is contained in the following tool fixing frame 3 on lower bolster 1 right side by bolt 2, is located at down the bottom knife 4 of 3 one jiaos of tool fixing frame; Cope match-plate pattern 10, be located at the last tool fixing frame 13 in cope match-plate pattern 10 left sides by bolt 12, be located at the cutter 14 of 13 1 jiaos of tool fixing frame, wherein: the lower fixture that it also comprises by upper clamping block 6, go up fastening spring 7, go up last clamping device that connecting bolt 8 and last fixed block 9 constitute and be made of clamp 15, following fastening spring 16, following connecting bolt 17 and following fixed block 18 down; Upper clamping block 6 is associated in last fixed block 9 by last connecting bolt 8, and last fastening spring 7 is located between upper clamping block 6 and the last fixed block 9, and last clamping device is contained in the right side of cope match-plate pattern 10 by bolt 11; Following clamp 15 is associated in following fixed block 18 by following connecting bolt 17, and following fastening spring 16 is located at down between clamp 15 and the following fixed block 18, and lower fixture is located at the left side of lower bolster 1 by bolt 19.
Operation principle of the present invention is: before the shearing, carry on the slide block of forcing press, the upper module that is contained on the slide block is separated with lower module on being contained in down workbench, bar is sent down the circular arc cutting edge place of tool fixing frame 3 to by conveyer, and stop gauge makes its location.During shearing, press ram is descending, and upper and lower module closure when upper clamping block 6 and last tool fixing frame 13 contact with bar, under the effect of last fastening spring 7 and following fastening spring 16, makes clamping device and lower fixture begin to produce radially clamping force.Along with the increase that cutter 14 and bottom knife 4 are sheared the degree of depth, the active force of last fastening spring 7 and following fastening spring 16 strengthens gradually, and radially clamping force increases thereupon, to reduce the distortion of sheared blank section.After cutter 14 and bottom knife 4 are finished shearing, press ram is up, the drive upper module rises, following clamp 15 in lower module bar under drive is sheared under the rebound effect of following fastening spring 16 is up, after upper and lower module is separated fully, the withdrawal of the material blocking rod of stop gauge, follow-up rod feeding, the bar that release is sheared enters shearing work next time again.
