Description
Technical field
The utility model relates to stamping technology field, particularly relates to a kind of floating jib die pipe punching hole mould.
Background technology
Punching press, under normal temperature condition, utilize the diel be arranged on forcing press, pressure is applied to raw material, raw material are produced be separated or plastic deformation, thus obtaining a kind of pressure processing method of required part, perforating die is mould raw material being stamped out various nibs, and raw material can be sheet material, circular pipe, truncated cone-shaped tubing etc.As shown in Figure 3, it is a round tube, the tube wall of round tube has the circular hole that two axially symmetrical, in production, the processing method of this part has two kinds usually, and one adopts centreless to punching method, this processing method, because not having mandrel to support when punching in the middle of pipe, pipe punching hole place is easy to distortion, and product quality is low; Also having a kind of is the method for cantilever mounted, although this method pipe has cantilever to support as mandrel, punch is longer, and cause punch strength to reduce, punch easily damages, and service life is short.
Utility model content
Problem to be solved in the utility model is, for the above-mentioned defect of prior art, provide a kind of floating jib die pipe punching hole mould, pipe punching hole place is not yielding, and product quality is high, and punch strength is high, long service life.
The purpose of this utility model is achieved through the following technical solutions.Floating jib die pipe punching hole mould, comprise upper bolster, first punch, die shoe, second punch, backing plate is fixedly connected with on the right side of upper bolster lower surface, backing plate lower surface is fixedly connected with the first fixed head, first punch is fixedly connected on the first fixed head, the second fixed head is fixedly connected with on the right side of die shoe upper surface, second punch is fixedly connected on the second fixed head, the left side of described die shoe upper surface is fixedly connected with two travellers, two traveller left-right situs, traveller is socketed sliding sleeve outward, elastic support structure is provided with below sliding sleeve, two positioning sleeves are fixedly connected with on the left of upper bolster lower surface, two positioning sleeve left-right situs, the upper end of traveller is positioned at positioning sleeve, cantilever female die left and right directions is horizontally disposed with, cantilever female die is provided with two sliding sleeve through holes, sliding sleeve is through sliding sleeve through hole, the right-hand member of cantilever female die is provided with the die through hole in an axis vertical direction, also be provided with the conical material-dropping hole in an axis horizontal direction, the macropore of material-dropping hole is positioned at the right side of cantilever female die, cantilever female die is provided with a location structure, location structure is positioned at the right side of sliding sleeve, the left side of die through hole.When adopting the die punching of this structure, be inserted in by the right-hand member of pipe from cantilever female die, patrix is descending, and two holes gone out by the first punch and the second punch on pipe, waste material skids off from material-dropping hole, owing to having cantilever female die to support as mandrel in pipe during punching, so pipe punching hole place not easily produces distortion, product quality is high, punch is divided into the first punch and the second punch respectively in the punching of both direction up and down of pipe, the length of punch is shorter, so the intensity of punch is high, and long service life.
As preferably, be socketed with the first block rubber outside the first described punch, the first block rubber is positioned at the first fixed head lower surface, is socketed with the second block rubber outside the second punch, and the second block rubber is positioned at the second fixed head upper surface.First block rubber plays cushioning effect when punching, and the second block rubber plays support tube, strengthens the rigidity of cantilever female die.
As preferably, described elastic support structure is spring.
As preferably, described positioning sleeve is provided with axial slotted hole, and the upper end of traveller is fixedly connected with spacer pin, and spacer pin is positioned at slotted hole.
As preferably, the first described punch and the end of the second punch are inclined-plane, and inclined-plane, to downward-sloping from left to right, facilitates blanking to skid off from material-dropping hole.
The beneficial effects of the utility model are, pipe punching hole place is not yielding, improves product quality, and punch strength is high, and service life is extended, and structure is simple, easy to operate.
