Abstract
The invention discloses a die for punching a universal long hole (through hole) in a round tube once. The die comprises a lower die holder, a lower die fixing plate, a first female die, a second female die, a stripper plate, an upper die holder, an upper die fixing plate, a male die, guide pillars and guide sleeves. The lower die fixing plate is mounted on the lower die holder. After being assembled, the first female die and the second female die are mounted on the lower die fixing plate, and then the stripper plate is mounted on the lower die fixing plate. The upper die fixing plate is mounted on the upper die holder, and then the male die is inlaid into the corresponding position of the upper die fixing plate. A lower die and an upper die are matched in cutting edge. The guide pillars and the guide sleeves are used for connecting the upper die holder with the lower die holder. In this way, the die performs linear motion in the axial direction of the guide pillars. The two guide pillars are distributed at the two sides of the rear portion of the die. The die aims at achieving the technical effects and has the beneficial effects that the double-side universal long hole (through hole) is punched in the round tube once, the shape of a machined part does not change, it is not needed to rotate the round tube to conduct secondary punching, and machining precision and production efficiency are improved.
Description
Technical field
The present invention relates to a kind of diel that can replace and be machined on pipe milling elongated hole, be specifically related to the disposable mould the two-sided omnipotent elongated hole (through hole) of pipe upper punch.
Background technology
Pipe is processed two-sided omnipotent elongated hole (through hole), it is all generally on common punch press after one side punch, pipe revolves turnback relocate and rush another side opening, or on milling machine Milling Machining, this processing mode causes two-sided hole not concentric sometimes, and production efficiency is low, the cycle is long, is not suitable for batch production.
Summary of the invention
The technical problem to be solved in the present invention is not need secondary punching, only needs once just the two-sided omnipotent elongated hole (through hole) of pipe upper punch, to improve the degree of accuracy of punching.
In order to solve above-mentioned technical problem, the present invention adopts the technical scheme to be: disposable the two-sided omnipotent elongated hole (through hole) of pipe upper punch.
The disposable mould the two-sided omnipotent elongated hole (through hole) of pipe upper punch includes lower mold frame, counterdie fixing plate, die 1, die 2, stripper, mold frame, upper mould fixed plate, punch, guide pillar, guide pin bushing.
The fixing plate of described counterdie is arranged on lower mold frame, and die 1 and die 2 are arranged on after installing on the fixing plate of counterdie, then is arranged on by stripper on the fixing plate of counterdie; Upper mould fixed plate is arranged on mold frame, then is embedded on upper mould fixed plate by punch correspondence position, and counterdie and upper mould cutting edge match.
Guide pillar, guide pin bushing connect mold frame and lower mold frame, so, axially do rectilinear motion at guide pillar, and two guide pillars are distributed in the both sides, rear portion of mould.
The curved inner radius of described die 1 is identical with part external diameter basic size, and finishing size is bigger; The external diameter of die 2 is identical with part internal diameter basic size, and finishing size is smaller.
Described die 1 and die 2 freely can change the outfit according to part machining shape with punch, and part two outer wall hole machined is once-forming.
The advantage that the invention solves the problems that and providing the benefit that: disposable pipe is rushed two-sided omnipotent elongated hole (through hole), it is not necessary to rotate pipe and carry out secondary punching, improve machining accuracy and production efficiency, reduce the amount of labour.
Accompanying drawing explanation
Accompanying drawing 1: a kind of disposable mould schematic diagram rushing omnipotent elongated hole (through hole) at pipe.
1, lower mold frame 2, counterdie fix plate 3, die 14, die 25, stripper 6, mold frame 7, upper mould fixed plate 8, punch 9, guide pillar 10, guide pin bushing.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described: the disposable mould in the omnipotent elongated hole of pipe upper punch (through hole) includes lower mold frame (1), counterdie fixing plate (2), die 1(3), die 2(4), stripper (5), mold frame (6), upper mould fixed plate (7), punch (8), guide pillar (9) and guide pin bushing (10), counterdie is fixed plate (2) and is arranged on lower mold frame (1), die 1(3) and die 2(4) install after be arranged on the fixing plate (2) of counterdie, then stripper (5) is arranged on the fixing plate (2) of counterdie; Upper mould fixed plate (7) is arranged on mold frame (6), then punch (8) is embedded in the upper correspondence position of upper mould fixed plate (7), matches with upper mould cutting edge by debugging counterdie. Guide pillar (9) and guide pin bushing (10) connect lower mold frame (1) and mold frame (6), so, axially do rectilinear motion at guide pillar (9), and two guide pillars (9) are distributed in the both sides, rear portion of mould.
Position and the pipe needing processing put into and die 2(4) internal, start lathe, start working, punch (8) in descending process with die 1(3) and die 2(4) limit the deformation position of workpiece, thus disposable can go out omnipotent elongated hole (through hole) on pipe.
Claims (4)
1. one kind disposable rushed the mould of omnipotent elongated hole (through hole) at pipe and including: lower mold frame (1), counterdie fix plate (2), die 1(3), die 2(4), stripper (5), mold frame (6), upper mould fixed plate (7), punch (8), guide pillar (9), guide pin bushing (10), it is characterised in that: counterdie is fixed plate (2) and is arranged on lower mold frame (1); Die 1(3) and die 2(4) install after be arranged on the fixing plate (2) of counterdie; Again stripper (5) is arranged on the fixing plate (2) of counterdie; Upper mould fixed plate (7) is arranged on mold frame (6); Then punch (8) is embedded in the upper correspondence position of upper mould fixed plate (7), die 1(3) and die 2(4) match with punch (8) cutting edge, guide pillar (9), guide pin bushing (10) connect mold frame (6) and lower mold frame (1), so, guide pillar (9) axially does rectilinear motion, and two guide pillars (9) are distributed in the both sides, rear portion of mould.
