Detailed description of the invention
For can technical characteristic of the present utility model and effect be described in detail, and can realize according to the content of this description, below in conjunction with accompanying drawing, embodiment of the present utility model be further illustrated.
Fig. 2 and Fig. 3 schematically shows the embodiment of a kind of upsetting squeeze punch in the numerous embodiment of the utility model.This upsetting squeeze punch comprises die holder 21, drift 22, pin 23 and two nuts 24.
In the lump see Fig. 6 and Fig. 7, die holder 21 comprises base plate 211 and punch case 212.Base plate 211 is slab construction.The centre that punch case 212 is positioned at base plate 211 1 surface is also protruding.Punch case 212 and base plate 211 are made into integration, and are such as fixedly connected by welding together after also can being separately made.
Punch case 212 one side opposing with base plate 211 has hole 2121.
In the lump see Fig. 4 and Fig. 5, one end of drift 22 is connecting portion 221, the operate portions 222 when its other end is for working.
Connecting portion 221 is set in punch case 212 and forms Detachable connection structure, and punch case 212 is connected better with connecting portion 221 adaptation.The present embodiment, connecting portion 221 adaptation is set in the hole 2121 of punch case 212.
Shown in Fig. 4 and Fig. 5, connecting portion 221 is cylindrical structure, and its sidewall has location blocking plane 224.Location blocking plane 224 has two sides, lays respectively at the position that connecting portion 221 sidewall is relative, the oblate structure of overall formation.The inwall in hole 2121 also has corresponding with location blocking plane 224 against plane respectively, location blocking plane 224 be resisted against the inwall in hole 2121 against plane, rotate in a circumferential direction around own axes in upsetting squeeze process to limit drift 22, meanwhile, be also convenient to locate when drift 22 is changed.This location blocking plane 224 and be applicable to the use of drift 22 of difformity, different size against planar structure.
Be understandable that, connecting portion 221 is not limited to above-mentioned shape and structure, and such as connecting portion 221 can be multiple edge body, cylindroid structure, etc.
The hole 2121 of punch case 212 is that counterbore is better.Connecting portion 221 is positioned at the end face of that end of punch case 212 and fit in this counterbore bottom surface, ensures the transmission of upsetting squeeze process power.
In the lump see Fig. 4-7, the first through hole 223 that the radial direction that has connecting portion 221 runs through, punch case 212 has and to be communicated with the first through hole 223 and the second through hole 2122 of coaxial line, and pin 23 is threaded onto in first and second through hole 223,2122, with ensure upsetting squeeze complete after delivery time mention drift 22.The diameter that the diameter of pin 23 is less than first and second through hole 223,2122 is better, is beneficial to pin 23 and installs, and ensures that upsetting squeeze process pin 23 does not stress, indeformable.
During construction, the drift 22 of different size inserts in punch case 1, the drift 22 that only need more renew after drift 22 weares and teares, and without the need to changing die holder 21 and pin 23.
In the lump see Fig. 3, for preventing pin 23 in upsetting squeeze process from sliding, the sidewall at the two ends that pin 23 lays respectively at outside the second through hole 2122 has external screw thread, and two nuts 24 screw fastening with these pin 23 two ends respectively.
Such as, but iting is noted that above-mentioned Detachable connection structure is not limited to said structure, can also be the screw being arranged at die holder 21 and the connecting portion screwed with this screw being arranged at drift 22 one end.
Drift 22 material of the present utility model can be selected but be not limited to anti abrasive mould steel, and remaining part adopts but is not limited to ordinary carbon steel, to reduce costs.
It should be noted that, each the concrete technical characteristic described in above-mentioned detailed description of the invention, in reconcilable situation, can be combined by any applicable mode.In order to avoid unnecessary repetition, the utility model is no longer described various possible combination.
Being described in detail the utility model above with reference to embodiment, is illustrative and not restrictive, in the change do not departed under the utility model general plotting and amendment, all within protection domain of the present utility model.
