The punching pin former
Technical field
The utility model relates to a kind of former, particularly a kind of punching pin former.
Background technology
As shown in Figure 1, punching pin former of the prior art comprises pedestal 1 more, pedestal 1 has upright portion 2, one side of upright portion 2 is provided with driving mechanism 3, the opposite side of upright portion 2 is provided with the revolving body 4 that is driven by driving mechanism 3, form jack 5 on the revolving body 4, first clamp body 6 inserts and is coupled in the jack 5 of revolving body 4, the 3rd clamp body 7 passes Socket walls with first clamp body 6 and revolving body 4 lockings, threaded engagement between second clamp body 8 and first clamp body 6, the big end 10 of punching pin 9 are installed between second clamp body 8 and first clamp body 6.Above-mentioned punching pin former must be with first clamp body 6, second clamp body 8 and the 7 whole dismounting of the 3rd clamp body when dismounting punching pin 9, and operation comparatively bothers during clamping, and operating efficiency is lower.
Summary of the invention
Problems such as the utility model purpose is to provide a kind of convenient mounting and clamping, and the punching pin former that can increase work efficiency has solved the clamping trouble that existing punching pin former exists, and operating efficiency is lower.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: it comprises pedestal, pedestal has upright portion, one side of upright portion is provided with driving mechanism, the opposite side of upright portion is provided with the revolving body by drive mechanism, described revolving body end is provided with first clamp body, be combined with second clamp body on first clamp body, described second clamp body is made of the square arcuate part of centre and the ear at two ends, form the space that clamps the big end of punching pin between the side's arcuate part and the first clamp body end face, described side's arcuate part is provided with the through hole that passes for the punching pin small end, is connected and fixed by bolt between the described ear and first clamp body.When adopting the utility model clamping punching pin, only need unload the bolt that is connected between first clamp body and second clamp body, can carry out dismounting to the punching pin before and after the processing, whole clamping and the process of taking off are all very convenient, can improve the operating efficiency of punching pin machine-shaping.
As preferably, described first clamp body forms depressed part corresponding to the ear position of second clamp body, and described depressed part forms screwed hole.Wherein, form the integral thickness that depression can reduce the punching pin former corresponding to the ear position of second clamp body, make the structure of punching pin former more compact at first clamp body.
As preferably, the through hole of the square arcuate part of described second clamp body is made of the rectangle part of centre and the arch section at two ends.
Therefore, the utlity model has convenient mounting and clamping, can improve the characteristics such as operating efficiency of punching pin processing and forming.

The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment 1: as shown in Figure 2, pedestal 1 has upright portion 2, one side of upright portion 2 is provided with driving mechanism 3, the opposite side of upright portion 2 is provided with the revolving body 4 that is driven by driving mechanism 3, the end of revolving body 4 is provided with first clamp body 6, be combined with second clamp body 8 on first clamp body 6, as shown in Figure 3 and Figure 4, second clamp body 8 is made of the square arcuate part 81 of centre and the ear 82 at two ends, form the space 11 that clamps the big end of punching pin between side's arcuate part 81 and first clamp body, 6 end faces, side's arcuate part 81 is provided with the through hole 811 that the small end 91 for punching pin 9 passes, through hole 811 is made of the rectangle part of centre and the arch section at two ends, first clamp body 6 forms depressed part 61 corresponding to the position of the ear 82 of second clamp body 8, depressed part 61 forms screwed hole, is connected and fixed by bolt 12 between the ear 82 of second clamp body 8 and first clamp body 6.
During the clamping punching pin, only need unload the bolt that is connected between first clamp body and second clamp body, can carry out dismounting to the punching pin before and after the processing, whole clamping and the process of taking off are all very convenient.
