Abstract
The invention discloses a traceless bending mold which comprises a mold body. A V-shaped concave opening is formed in the middle of the mold body. Supporting shafts are arranged at the positions, on the two sides of the concave opening, on the mold body respectively. Each supporting shaft is sleeved with a carrying flat plate. An arc-shaped groove is formed in the bottom of each carrying flat plate and is in rotary fit with the cylindrical face of the corresponding supporting shaft. The width of the openings of the grooves is smaller than the diameter of the supporting shafts. The traceless bending mold is simple in structure, convenient to use and capable of improving the bending quality and production efficiency of copper bars.
Description
Technical field
The present invention relates to bending equipment technical field, particularly relate to a kind of Traceless bending die tool.
Background technology
The copper bar that high ferro uses needs to carry out Bending Processing, the Bending Mould used at present is generally made up of the bed die of upper punch, band recess, in process, copper bar is larger by the pressure of lower module load line, and copper bar is in bending draw-texture process, be subject to the friction of bed die, easily cause copper bar surface significantly impression.Because copper bar is higher to its surface requirements, often requirement can not have folding line, and traditional processing method pads adhesive plaster or cloth on lower module, but adhesive plaster or cloth will break after bending several times, and product will be caused impaired.
Summary of the invention
In order to solve deficiency of the prior art, the object of the present invention is to provide a kind of product surface can not produce impression and impaired Traceless bending die tool.
For achieving the above object, the present invention is by the following technical solutions:
A kind of Traceless bending die tool, comprise die ontology, the middle part of die ontology is provided with the recess of V-arrangement, is respectively equipped with back shaft on described die ontology and in the both sides of recess, and each back shaft is all socketed with loading flat board; The bottom of described loading flat board is provided with the groove of circular arc, and the face of cylinder of groove and back shaft is rotatably assorted, and the width of described slot opening is less than the diameter of back shaft.
The face of cylinder of described back shaft is evenly distributed with blind hole, in blind hole, is embedded with profit contaminated product fat.
The two sides of described recess are equipped with spring.
Described back shaft and die ontology are formed in one.
The bottom of described recess is provided with rounding.
The present invention adopts above technical scheme, has following beneficial effect:
1, when carrying out bending to copper bar, in one plane, be placed on by copper bar on two loading flat boards, drift applies pressure on copper bar in the upper surface of two loading flat boards, makes copper bar produce bending.Copper bar is when stressed, and loading flat board can rotate on back shaft, can not produce relative motion between copper bar and loading flat board, and both contact surfaces remain unchanged, and the surface of loading flat board would not produce cut.
2, the A/F of loading flat plate bottom groove is less than the diameter of back shaft, can prevent loading flat board from coming off from back shaft in rotary course like this.
3, the profit contaminated product fat on back shaft can play lubrication, prevent loading dull and stereotyped with back shaft for a long time relative operate after occur wearing and tearing, raising service life.
4, during copper bar bending, spring plays cushioning effect; After copper bar bending completes in addition, loading flat board can automatically reset under the action of the spring, enhances productivity.
In a word, simple, easy to use, the bending quality that can improve copper bar of Traceless bending die lamps structure of the present invention and production efficiency.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the present invention is described in further details:
Fig. 1 is the structural representation of Traceless bending die tool of the present invention;
Fig. 2 is the profile of back shaft in the present invention.
Detailed description of the invention
As shown in Figure 1 or 2, the present invention includes die ontology 1, the middle part of die ontology 1 is provided with the recess 11 of V-arrangement, the bottom of recess 11 is provided with rounding, die ontology 1 is respectively equipped with back shaft 2 in the both sides of recess 11, back shaft 2 and die ontology 1 are formed in one, and each back shaft 2 is all socketed with loading flat board 3; The bottom of loading flat board 3 is provided with the groove of circular arc, and the face of cylinder of groove and back shaft 2 is rotatably assorted, and the width of slot opening is less than the diameter of back shaft 2, can prevent loading flat board 3 from coming off from back shaft 2 in rotary course like this.
The face of cylinder of back shaft 2 is evenly distributed with blind hole 21, in blind hole 21, is embedded with profit contaminated product fat (not shown).Profit contaminated product fat on back shaft 2 can play lubrication, occurs wearing and tearing after preventing that loading dull and stereotyped 3 and back shaft 2 are long-time relative and operating, raising service life.
Operation principle of the present invention: when carrying out bending to copper bar, in one plane, be placed on by copper bar on two loading flat boards 3, drift applies pressure on copper bar in the upper surface of two loading flat boards 3, makes copper bar produce bending.Copper bar is when stressed, and loading flat board 3 can rotate on back shaft 2, and can not produce relative motion between copper bar and loading flat board 3, both contact surfaces remain unchanged, and the surface of loading flat board 3 would not produce cut.
In addition, the two sides of recess 11 are equipped with spring 4.During copper bar bending, spring plays cushioning effect; After copper bar bending completes in addition, under the effect of spring 4, loading flat board 3 can automatically reset, and enhances productivity.
