Description

Cylindrical member side opening punch die
Technical field
The utility model relates to stamping technology field, particularly relates to a kind of cylindrical member side opening punch die.
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 2, be a kind of cylindrical member, the side of cylindrical member is also that external peripheral surface has a through hole, and this through hole distance cylindrical member bottom surface only has 2.5mm, adopt conventional structure, die hole on die also only has 2.5mm apart from the minimum thickness of its bottom surface, causes the intensity of die too low, makes die be easy to damage, need often to change die, production cost is high, and production efficiency is low, affects production process.
Utility model content
Problem to be solved in the utility model is, for the above-mentioned defect of prior art, provides a kind of cylindrical member side opening punch die, eliminates strength of concave mould low, hold flimsy problem, reduce production cost, improve production efficiency, production is carried out smoothly.
The purpose of this utility model is achieved through the following technical solutions.Cylindrical member side opening punch die, comprise upper bolster, die shoe, die, punch, upper bolster lower surface is fixedly connected with backing plate, backing plate lower surface is fixedly connected with fixed head, described die is fixedly connected on the lower surface of fixed head, one push rod mobile link is on backing plate and fixed head, the die hole of die is passed in the lower end of push rod, described die shoe comprises a base and a gripper shoe, gripper shoe vertically arranges and is fixedly connected on base, punch comprises connecting portion and punching boss, connecting portion is elongated, be horizontally disposed with, vertically be fixedly connected with on the supporting plate, punching boss is fixedly connected on connecting portion and protrudes straight up, punch is socketed certain circle of position cylinder outward, location cylinder is provided with a punching boss through hole, be connected in the punching boss through hole of location cylinder in punching boss, gap is had between the connecting portion of punch and location cylinder, some second springs are provided with between the upside of connecting portion and cylinder.During work, cylindrical member is loaded location cylinder, patrix is descending, die is pressed in cylindrical member, and cylindrical member is along with location cylinder glide downwards, and the second spring is compressed, punching boss on punch goes out circular hole in cylindrical member, and blanking is pressed into die hole, and push rod moves up simultaneously, patrix is up, second springback, cylindrical member is moved, and can be taken out, meanwhile, blanking is released die hole by push rod.This structure, die upper male mould under, avoid the flimsy problem of the too low appearance of strength of concave mould, reduce production cost, improve production efficiency, production is carried out smoothly.
As preferably, described upper bolster lower surface is provided with the first shrinkage pool, the first spring is provided with in first shrinkage pool, backing plate is provided with the first through hole, fixed head is provided with the second through hole, described push rod is in T shape, and the upper end of push rod is positioned at the first through hole, and the die hole of the second through hole and die is passed in the lower end of push rod.Structure is simple, easy for installation.
As preferably, be provided with some second shrinkage pools on the upside of described connecting portion, the second spring is positioned at the second shrinkage pool, easy for installation.
As preferably, the upper surface of described upper bolster is fixedly connected with a die shank, easy for installation.
The beneficial effects of the utility model are, eliminate strength of concave mould low, hold flimsy problem, reduce production cost, improve production efficiency, and production is carried out smoothly, and structure is simple, and making and installation is convenient.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of cylindrical member.
Detailed description of the invention
Below the utility model is described in further detail in conjunction with the accompanying drawings and embodiments:
Embodiment, as shown in Fig. 1, cylindrical member side opening punch die, be made up of patrix and counterdie, patrix comprises die shank 1, upper bolster 2, backing plate 4, fixed head 5, die 7, push rod 6, die shank adopts and is threaded into the upper surface that formula is fixedly connected on upper bolster, upper bolster lower surface is provided with the first circular shrinkage pool, the first spring 3 is provided with in first shrinkage pool, backing plate is provided with the first circular through hole, first shrinkage pool is identical with the diameter of the first through hole, fixed head is provided with the second circular through hole, the diameter of the first through hole is greater than the second through hole, backing plate is positioned at the lower surface of upper bolster, fixed head is positioned at the lower surface of backing plate, upper bolster, backing plate, fixed head four screws and two straight pins are fixed together.Push rod is in T shape, the upper end of push rod is positioned at the first through hole, first spring is positioned at above push rod, the second through hole of fixed head is passed in the lower end of push rod, die is tubular, and there is a step upper end, and die is screwed the lower surface being connected to fixed head by step, the die hole of die is passed in the lower end of push rod, and the lower surface of push rod is concordant with the lower end of die hole.Counterdie is by die shoe, punch 10, location composition such as cylinder 9 grade, die shoe comprises base 11 and gripper shoe 12, gripper shoe is vertically arranged and screw is fixedly connected on base, punch comprises connecting portion and punching boss, connecting portion is the long cylinder bodily form, be horizontally disposed with, connecting portion is through the through hole in gripper shoe, vertically be fixedly connected with on the supporting plate by pad 13 screw, punching boss is cylindrical, punching boss can adopt to be welded and fixed and is connected to connecting portion and protrudes straight up, punch is socketed setting circle cylinder outward, location cylinder is provided with the punching boss through hole of a circle, be connected in the punching boss through hole of location cylinder in punching boss, gap is had between the connecting portion of punch and cylinder, two circular the second shrinkage pools are provided with on the upside of connecting portion, the lower end of the second spring 14 is positioned at the second shrinkage pool, the upper end of the second spring withstands on the inwall of location cylinder.During work, cylindrical member 8 is loaded location cylinder, patrix is descending, die is pressed in cylindrical member, and cylindrical member is along with location cylinder glide downwards, and the second spring is compressed, punching boss on punch goes out circular hole in cylindrical member, and blanking is pressed into die hole, push rod moves up simultaneously, and the first spring is compressed; Patrix is up, and the second springback, cylindrical member is moved, and cylindrical member can be taken out, and meanwhile, the first springback, blanking is released die hole by push rod.This structure, die upper male mould under, avoid the flimsy problem of the too low appearance of strength of concave mould, reduce production cost, improve production efficiency, production is carried out smoothly.
