Abstract
A shearing die unit with automatic material-pressing part for rod material is composed of blanking die, supporting locator, great smooth plate, upper die holder, shearing blade plates and regulating screw bolt. It features its automatic material-pressing part, which is installed to the blanking die holder and is composed of several springs, movable pressing plate, several guiding posts, upper pressing plate, wedge, cylinder and matched two Harff semi-dies. It features that when a a rod is sheared, it can be tightly pressed to make its both end segments to be straight.
Description
(1) technical field
The present invention relates to universal crank press, relate in particular to the shearing die of forging industry bar accurate-shearing.
(2) background technology
As shown in Figure 1, the bar shearing die that forging industry is at present commonly used, its structure comprise blanking die parts 1, supporting positioning element 2, massive plate 3, adjusting screw(rod) 6, cut material knife plate 5 and on touch seat 4, wherein, cut the material knife plate 5 be installed in touch the seat 4 in, adjusting screw(rod) 6 be fixed on the supporting positioning element 2 on.Blanking die parts 1 and supporting positioning element 2 are installed in respectively on the massive plate 3.By cut round bar 9 pass blanking die parts 1 by the supporting positioning element 2 adjusting screw(rod) 6 carry out spacing.Cut material knife plate 5 by on touch seat 4 and driven by external pressure machine slide block and move up and down, realize shearing to bar.
Because the intensity and the hardness of steel bar are all very high, under the effect of side force, on touch seat 4 certain elastic deformation can take place, the gap of cutting material knife plate 5 and blanking die parts 1 is increased, be sheared the bar section and tilt seriously, influence shearing quality and later forging process.
In order to improve shear precision, therefore, the applicant number is 02217033.2 in Chinese patent application, the utility model name is called disclosed a kind of technical scheme in " a kind of bar shearing die ", promptly on the basis of above-mentioned bar shearing die, also be provided with a guider between blanking die parts and supporting positioning element.This guider comprises that the take-up housing that is " " font of touching seat 4 on ccontaining, four lay respectively at four angles of take-up housing inwall with the axially movable guide rail of the made slide block of vertical direction setting.
Adopt this structure, on touch between seat 4 guide rails in take-up housing and move, therefore, cut during shearing material knife plate 5 with on touch seat and 4 be limited in all the time in the guiding stroke of guide rail, avoid knife plate because of the stressed strain that produces, made to be cut and expect that the section end face is straight, improved shear precision.
But the bar 9 from steel mill directly dispatches from the factory because diameter has bigger tolerance, and all has bigger radially burr in its end, makes bar 9 be subjected to certain restriction by blanking die parts 1 time.Like this, must strengthen the internal diameter of the sleeve mould 13 in the blanking die parts 1, make the sleeve mould 13 and the gap of bar 9 increase, strengthen the warpage amplitude of bar 9, it is serious to be cut material section end slope.Influenced shearing quality.
Medium-sized have the shearing die of material pressing device that the next direct binder of cylinder or spring normally is set on mould, because compressed air and spring all have certain compressibility, compressed air and spring are subjected to certain compression when shearing force is big, weakened pressure-plate-force, still will make bar produce certain warpage.
(3) summary of the invention
The object of the present invention is to provide a kind of bar that can prevent in shear history, to produce the bar shearing die of the band automatic pressing material device of warpage, assurance shearing quality.
A kind of bar shearing die provided by the present invention with the automatic pressing material device, comprise the blanking die parts, the supporting positioning element, massive plate, on touch seat, be installed in and touch cutting the material knife plate and being installed in the adjusting screw(rod) that supports on the positioning element in the seat, wherein, the blanking die parts comprise die holder, sleeve pressing plate and the sleeve mould between die holder and sleeve pressing plate, again: blanking die parts and supporting positioning element are installed on the massive plate respectively, it is characterized in that: it also comprises on the die holder that is installed in the blanking die parts and is positioned at the automatic pressing material device in the sleeve mould outside, this material pressing device is included in some springs that the die holder bilateral symmetry is provided with, movable pressing board on some springs, some guide pillars, top board, wedge, cylinder and two involutory Hough half modules that are positioned under the movable pressing board, the two ends up and down of described guide pillar respectively be provided be contraction-like on, get out of a predicament or an embarrassing situation, and an end of each guide pillar penetrates movable pressing board and enters in each spring center hole, and be positioned on the die holder by getting out of a predicament or an embarrassing situation of guide pillar, the other end of each guide pillar seals in top board, and by the location top board of topping bar of guide pillar; The upper surface of described movable pressing board is made up of an inclined-plane and a plane, and the lower surface of described wedge is an inclined-plane that matches with the inclined-plane of movable pressing board upper surface; The piston of described cylinder is fixedlyed connected with wedge, and drives wedge make horizontal reciprocating movement on the inclined-plane of movable pressing board, does binder motion up and down thereby drive movable pressing board.
The bar shearing die of above-mentioned band automatic pressing material device, also comprise one at blanking die parts and supporting the guider between the positioning element; This guider comprises that the take-up housing that is " " font of touching seat on ccontaining, four lay respectively at four angles of take-up housing inwall with the axially movable guide rail of the made slide block of vertical direction setting.
The bar shearing die of above-mentioned band automatic pressing material device wherein, also can be provided with a backing plate under the top board of material pressing device.
Adopted above-mentioned technical solution, promptly utilize cylinder to promote wedge and make horizontal reciprocating movement, thereby drive movable pressing board and do binder motion up and down, because the self-locking action of wedge and movable pressing board, even bigger shearing force also can make the movable pressing board bar of pushing down tightly prevent that bar from producing tilting, adopt the present invention that bar can both tightly be pushed down when shearing each time, can access the straight material section in two ends, guarantee shearing quality.
