The invention discloses a die for V-shaped bending and with changeable angles, and relates to the field of machining. The die for V-shaped bending and with the changeable angles is used for solving the problems that when V-shaped bending is carried out on different metal at different processing temperatures, a large amount of computer simulation often needs to be carried out, various bending dies with different angles need to be trial-produced, thus a forming angle, meeting a definite condition, of a die for V-shaped bending and with an expected actual sheet material bending angle can be obtained, time and labor are wasted, and a large economical burden can be caused. The die for V-shaped bending and with the changeable angles mainly comprises an upper die base, a lower die base, an upper die body, a lower die body, upper die supporting plates, lower die supporting plates, guide pillars, guide sleeves, bolts and pins, wherein the upper die body and the lower die body are formed by separated metal plates, and the forming angle of the upper die body and the forming angle of the lower die body can be adjusted within a large range. The die for V-shaped bending and with the changeable angles has the advantages that due to adjustment of angles of the upper die body and angles of the lower die body, accurate results of bending angles, required to be achieved by V-shaped bending, of different metal at different temperatures can be obtained, the effect of being multi-purpose can be achieved, cost for die manufacturing can be reduced, and manpower and material resources can be saved.

Description

Variable-angle V-type bending mould
Technical field
The present invention relates to field of machining, particularly a kind of variable-angle V-type bending mould.
Background technology
In Aeronautics and Astronautics, automobile and other field of machining, being of wide application of bending mould, a large amount of plate shaping operations is arranged in the cold working, and a lot of complicated punch formings come down to form by the V-type of many parts is crooked, and the brake forming of accurately controlling plate just seems particularly important.
Brake forming for metal blank, the existence of rebound phenomenon can cause the inaccurate of angle of bend, existing V-type bending mould generally all is that upper and lower mould moulding angle is fixed when designing, so just, can only process a kind of V-type crooked sheet material of fixed angle, yet, in different temperatures, in the process of different materials, same angle of bend often can obtain different brake forming angles with shaping speed.The V-type bending of under different processing temperatures, carrying out for different metal, often need to carry out more computer mould and fit the mould of manufacturing experimently out multiple different angle, be met the V-type bending mould moulding angle of determining the actual plate angle of bend of expecting under the condition thereby experimentize, relatively waste time and energy and can cause than large economy and bear.
Summary of the invention
Be computer simulation, the trial-production expense that reduces mould, use manpower and material resources sparingly, and under different temperatures, obtain a series of different expection angle of bend for different metal material, thereby determine the actual moulding angle of V-type bending mould under the concrete condition of work, the present invention has designed a kind of variable-angle V-type bending mould.
The present invention includes upper die and lower die, upper bolster, die shoe, patrix gripper shoe, counterdie gripper shoe, guide pillar, guide pin bushing, pin and bolt.Wherein counterdie has designed 3 covers, and the angle adjustable range is respectively 0 ° ~ 90 ° between the counterdie metallic plate, and 90 ° ~ 135 °, 135 ° ~ 157.5 °.Be convenient and describe that the present invention is that 90 ° ~ 135 ° one group is example with counterdie metallic plate angle mainly, and has provided other two groups of counterdie schematic diagrames in the accompanying drawings.
The part of the upper die of this V-type bending mould is made up of four metallic plates, every metallic plate two ends all are shaped on the hole, four metallic plate head and the tail connect to form patrix successively, position by pin between the metallic plate, upper mould fixed plate is two metallic plates, the below is shaped on the hole with patrix hole uniform internal diameter bottom, and has groove on the plate.Be shaped on die shank on the upper bolster, an end is shaped on two holes and is used for mounting guide sleeve.Counterdie is two metallic plates, every metallic plate is the circular arc of same diameter with the patrix corresponding position, there is complementary breach at the circular arc position of two metallic plates in order to work in coordination, the metallic plate sample is added can be contacted with counterdie maintenance face man-hour, and respectively there is circular hole counterdie metallic plate both sides, be used for cooperating by pin with die shoe, the end that the counterdie metallic plate is relative with arc section is shaped on the hole, cooperates by pin and counterdie gripper shoe.The counterdie gripper shoe is two metallic plates, and an end connects counterdie by pin, and the other end cooperates by the groove on bolt and the die shoe and fixes.Die shoe is a metal derby, the centre of the face that contacts with counterdie is shaped on and the counterdie isometrical interior concave arc of circular arc bottom, can when changing angle, counterdie contact with its maintenance face all the time, thereby bear the stamping press in the forming process, die shoe one side has two holes, be used for installing guide pillar, the guide pillar diameter equates with the guide pin bushing internal diameter.
Beneficial effect of the present invention is: 1. patrix of the present invention is made up of four metallic plates, can flexible modulation moulding angle, and adjustable range is big, can contain the various moulding angles of V-type bending mould, uses bolting and unclamps conveniently; 2. counterdie of the present invention can be adjusted angle flexibly, can fit fully with patrix during moulding, and realize secure fixation by the counterdie gripper shoe, and the effect simultaneous interpretation non-adjustable V-type bending mould effect of uniting is identical after the fixed angle; 3. die shoe is shaped on the groove that matches with counterdie, can effectively support counterdie, and for counterdie location and make that the counterdie angular adjustment is flexible, the counterdie gripper shoe is slided between its groove, can fix fast by bolt; 4. by the angular adjustment of upper and lower mould, can obtain accurate result for the crooked angle of bend that requires to reach of the V-type of different metal under different temperatures, reach the effect of one module multiple usages, save Mold Making expense and manpower and materials.
