Description

The wheel spoke that corner cut by a kind of band makes drawing die
Technical field
The utility model relates to wheel spoke manufacture technology field, is specifically related to the wheel spoke making drawing die that corner cut by a kind of band.
Background technology
It is separate operation that current wheel spoke stretches with corner cut, it is the cutting operation first carrying out four angles, and cutting operation also needs just can complete for four times, and then carry out stretching operation, this operating type in two steps not only complex procedures causes production efficiency lower, but also the position, central shaft bearing bore hole being easy to the wheel spoke causing producing occurs the phenomenon that departs from and causes the situation of scrapping.Therefore, design that a kind of operation is simple, production efficiency is high, the wheel spoke of central shaft bearing bore hole position accurate positioning makes drawing die and seem very necessary.
Utility model content
The utility model is to solve existing wheel spoke cutting operation often, the loaded down with trivial details technique of carrying out central shaft bearing bore location is also needed to cause production efficiency low after cutting, easily there is the phenomenon that departs from and cause the deficiency of scrapping in location, position, central shaft bearing bore hole, provides a kind of and cut the wheel spoke that clout is simple, quality is high, operation is simple, production efficiency is high, corner cut by a kind of band of central shaft bearing bore hole position accurate positioning and make drawing die.
Above technical problem is solved by following technical proposal:
The wheel spoke that corner cut by a kind of band makes drawing die, comprise lower bolster and the cross cope match-plate pattern in " ten " font, the upper surface of lower bolster is provided with columniform punch cushion block, the upper surface of punch cushion block is provided with the punch of the groove match of upper surface and wheel spoke, and the lower surface of punch overlaps with the upper surface of punch cushion block and is fixedly connected with completely; Be provided with bottom in the upper surface center of punch straight down and drop on punching cylinder fixing hole on above punch cushion block, in punching cylinder fixing hole, be installed with the punching cylinder that punching expansion link is arranged straight up straight up, on the punching expansion link top of punching cylinder, the punching head that can horizontally rotate be installed straight up; The lateral wall of punch cushion block is arranged with holding pad cushion block under the annular that lower surface drops on lower bolster upper surface, and holding pad be arranged with the annular that lower surface drops under annular on holding pad cushion block upper surface on the lateral wall of punch cushion block under; Holding pad cushion block all around respectively straight up just to being provided with four guide pillars under annular, and the center line of two center lines of two guide pillars in left and right and punching head is in same horizontal perpendicular, before and after the center line of two center lines of two guide pillars and punching head in same longitudinal perpendicular, horizontal perpendicular and longitudinal perpendicular orthogonal and intersect on the center line of punching head; Lower bolster upper surface respectively under every root guide pillar and adjacent annular between holding pad is provided with straight up the shearing tool rest that madial wall is circular arc vertical plane; Four terminations of cross top board are vertically slidably connected on four guide pillars, the lower surface of cross top board is fixedly connected with upper padding plate, upper padding plate lower surface directly over punching head is provided with punching post straight down, be provided with punching groove straight up in the lower surface center of upper punching post, and the center line of punching groove and the center line of punching head are on the vertical straight line of same; Upper padding plate lower surface under annular directly over holding pad is provided with straight down holding pad cushion block in annular, in annular holding pad cushion block lower surface on be fixedly connected with holding pad in annular, and in annular, the outer lower end edge of holding pad is connected with the edge of a knife shearing tool rest is shearing, and in annular, the edge, interior lower end of holding pad is convex.
This programme in use, allows four shearing tops of tool rest and the top of punching head on same horizontal plane, and allows the center of square sheet material be positioned at the top end of punching head.Then allow cross cope match-plate pattern toward pressing down, the upper holding pad of annular is allowed to be pressed on square sheet material, and now going up punching post lower end is also pressed on square sheet material, then stop cross cope match-plate pattern toward pressing down, then allow the punching expansion link of punching cylinder up extend promotion punching head up move, the punching head up result of movement gets central shaft bearing bore in the center of square sheet material.After central shaft bearing bore has been punched, punching cylinder has stopped extending, and keeps current elongation state, makes central shaft bearing bore also continue to be enclosed within punching head.Then square sheet material is rotated, and allow four of square sheet material corners face shearing tool rest respectively, then cross cope match-plate pattern is allowed to continue toward pressing down, in annular holding pad outer lower end edge and shear tool rest the edge of a knife between can produce cutting power, this cutting power just can cut away the unnecessary sheet material of square sheet material four angles place redundance, and at this moment the useful part of square sheet material becomes circular sheet material.After square sheet material is cut into circular sheet material, continue to allow cross cope match-plate pattern continue toward pressing down, the surrounding that in annular, the edge, interior lower end of holding pad and lower surface promote circular sheet material jointly moves down, and cross cope match-plate pattern can be stopped to continue toward pressing down when time on the upper surface that the lower surface of holding pad in annular is pressed on the lower holding pad of annular.Then allow the punching expansion link of punching cylinder down shrink until the expansion link that punches exits from central shaft bearing bore, after then allowing the continuation of cross cope match-plate pattern up move, shaping wheel spoke product can be taken out.This programme cuts that clout is simple, quality is high, operation is simple, production efficiency is high, the position accurate positioning of central shaft bearing bore hole.
As preferably, every root guide pillar upper and lower side respectively slip cap be provided with guide pin bushing, the guide pin bushing upper end of guide pillar upper end is fixedly connected on the lower surface of cross top board, and the guide pin bushing lower end of guide pillar lower end is fixedly connected on the upper surface of lower bolster.Guide pin bushing adds the height that cross top board moves up and down, and is convenient to square sheet material to carry on processing platform, is also convenient to take out processing shaping wheel spoke product, simple and easy to use.
As preferably, the cross top board above guide pin bushing inner chamber is provided with through hole.Add the height that cross top board moves up and down, and cross top board can be allowed to take off the cross top board changing other models, enhance the scope of application.
As preferably, the edge of a knife madial wall shearing tool rest upper end extends 1-3 millimeters long to inward side, the edge of a knife upper surface outer end of shearing tool rest upper end is the inclined-plane that leans outward, and the edge of a knife upper surface the inner of shearing tool rest upper end is level of shear mouth plane, and the width of level of shear mouth plane is 2-4 millimeter.This structure makes the edge of circular sheet material not easily be pressed on shearing tool rest, is convenient to take out operation.
The utility model can reach following effect:
The utility model is easy to carry out clout to the square sheet material of wheel spoke and cuts, and clout cuts simply, shaped article quality is high, operation is simple, production efficiency is high, the position accurate positioning of central shaft bearing bore hole, and cost is low, and reliability is high.
