Shape fixed plate 15 drives shaping convex block 22 to put in shaping groove 21 and carries out shaping to the antetheca and rear wall of workpiece 20, until positioning
The bottom of screw 10 is contacted with the top of tool assembly 2, and stretching stay column 4 at this time can not drive repoussage shape fixed plate 15 to move downward,
Shaping to workpiece 20 is completed, since positioning screw 10 is contacted with the top of tool assembly 2, makes repoussage shape fixed plate 15 to workpiece
20 be pressed onto to a certain degree after can not press again, thus avoid making part shaping excessive due to the strength of staff is different
The problem of causing secondary deformation, no matter the much strength of staff, 20 size of workpiece after shaping is complete in acceptability limit,
Improve qualification rate, at the same positioning screw 10 with slider plate 11 to be threadedly coupled, it is possible to by rotational positioning screw 10 come
The distance that repoussage shape fixed plate 15 moves down in adjusting, it is convenient to difference so as to adjust the shaping dynamics to workpiece 20
The workpiece 20 of deformation extent carries out shaping, and after the completion of shaping, release handle 7 drives under the action of the reset of spring 12 and stretches stay column 4
It is moved upwards with upper repoussage shape fixed plate 15, contacts, restore to initial bit with 14 bottom of limiting cylinder at the top of slider plate 11
It puts.
The shaping mould can effectively and rapidly carry out deformation part shaping, and the primary multiple workpiece of shaping simultaneously,
Production efficiency is improved, reduces cost of labor, reduces labor intensity, improves qualification rate, it is convenient and efficient.
The utility model is described in detail above by embodiment, but the content is only the utility model
Preferred embodiment, it is impossible to be construed as limiting the scope of the utility model.It is all to be made according to application scope of the utility model
All the changes and improvements etc., should all still belong within the patent covering scope of the utility model.
