Abstract
The invention discloses a forming process for end caps of four-way reversing valves for air conditioners. The process includes taking adaptive copper bars, blanking and cutting the copper bars into round bars of required length, and positioning the round bars at corresponding positions of multi-station pressing equipment; and pressing the round bars at a first station, a second station, a third station, a fourth station and a fifth station to perform press forming on the round bars, and completing forming. The process has the advantages that adaptive copper bars are used as raw materials to be cut into the required lengths, the round bars are formed by pressing, and accordingly raw material utilization rate is high, spillage of materials is lowered, production efficiency is improved, waste of turnover is reduced, and the like. A cold header integral machining and simplified machining process can be adopted, and machining efficiency is improved.
Description
Technical field
The present invention relates to air conditioner parts process technology, especially a kind of contour machining procedure of idle call four-way change-over valve end cap.
Background technology
End cap product on idle call four-way change-over valve, it is when production and processing, many employings are at monoblock copper coin upper punch circle of contact sheet, then the processes of carrying out punch press stretching forms, see Fig. 1, this processing technology step is numerous and diverse, comprising the multinomial work flows such as die-cut, punching press 1, punching press 2, punching press 3, shaping, deburring, need in process to be connected each road flow process by transferring in semi-finished product week, and this processing technology is more serious to waste of raw materials, scrap rate on average reaches 40%, and the cost of raw material is higher.
Summary of the invention
The present invention, for solving prior art in use Problems existing, provides a kind of and reduces spillage of material, the contour machining procedure of the idle call four-way change-over valve end cap of improving production efficiency
The technical scheme that the present invention solves existing issue is: a kind of contour machining procedure of idle call four-way change-over valve end cap, step following (1) gets the copper rod adapted, blanking cuts into the pole of Len req, pole is positioned the pressing equipment corresponding position of multistation; (2) punching press pole, stamps out fillet in station one corresponding position by bottom pole, and turns over turnback; (3) by step (2) punching press pole be positioned over station two corresponding position, little pole top is stamped out a pit; (4) by step (3) punching press pole being positioned over station three corresponding position, workpiece top is stamped out bowl structure; (5) by step (4) punching press pole being positioned over station four corresponding position, by punch forming bottom bowl-shape workpiece; (6) by step (5) punching press pole being positioned over station five corresponding position, by workpiece punch forming, machine.
As a further improvement on the present invention, above-mentioned step (1)-(6) are integrally machined by cold headers.
As a further improvement on the present invention, above-mentioned pole is by manipulator clamping, and described manipulator interval successively circular flow arrives between station five in station one, and described copper rod is disc type copper rod.
The present invention compared with prior art, get the copper rod that adapts intercept as raw material cutting needed for length, by punching press by pole punch forming, utilization rate of raw materials is high, reduction spillage of material can be reached, improving production efficiency, reduce the excellent effect such as turnover waste.The present invention can adopt cold headers one manufacture simplification processing technology, improves working (machining) efficiency.
Accompanying drawing explanation
Fig. 1 is the process chart of prior art.
Fig. 2 is process chart of the present invention.
Detailed description of the invention
See Fig. 2, step of the present invention is as follows: (1) gets the copper rod adapted, and blanking cuts into the pole of Len req, pole is positioned the pressing equipment corresponding position of multistation; Wherein copper rod is disc type copper rod, one enclose fold come, can a lot of stub bar of maximized minimizing and material tail.(2) punching press pole, stamps out fillet in station one corresponding position by bottom pole, and turns over turnback; (3) by step (2) punching press pole be positioned over station two corresponding position, little pole top is stamped out a pit; (4) by step (3) punching press pole being positioned over station three corresponding position, workpiece top is stamped out bowl structure; (5) by step (4) punching press pole being positioned over station four corresponding position, by punch forming bottom bowl-shape workpiece; (6) by step (5) punching press pole being positioned over station five corresponding position, by workpiece punch forming, machine.
Integrally machined by cold headers for the ease of processing above-mentioned steps (1)-(6), pole is by manipulator clamping, and manipulator interval successively circular flow arrives between station five in station one.
