Abstract
The utility model discloses a kind of flat mould of contracting preparing bolt with one end bent back, include and carry out punch die and to contract flat punch die and the former of bolt, it is characterized in that: described former is provided with bolt positioning hole, described punch die is socketed with punch die cover, the pushing block of red needle and fixing red needle is provided with in described punch die cover, the front end of this red needle is placed in punch die jaws, this jaws front end is provided with the flat step of contracting, also elastic device is provided with in described punch die cover, described elastic device one end connects punch die cover inwall, and the other end connects pushing block.The utility model is rational in infrastructure, solves the problem that bolt is extracted by punch die.
Description
Technical field
The utility model relates to the improvement invention that a kind of securing member makes mould, particularly relates to a kind of improvement invention preparing the flat mould of contracting of bolt with one end bent back.
Background technology
In prior art; when the flat operation of the contracting preparing bolt with one end bent back; often there will be " lot " problem, refer to that workpiece is pulled out by punch die, its reason be punch die contracting flat after frictional force; be far longer than the frictional force of former to bolt; and solve lot sizing problem and can adopt scheme gauge or diameter of wire overstriking, simultaneously former undergauge, although lot sizing problem can be solved, gauge or diameter of wire overstriking; the manufacturing cost of bolt rises, and does not calculate very much economically.
Utility model content
Technical problem to be solved in the utility model overcomes the deficiencies in the prior art, provides a kind of rational in infrastructure, flat mould of contracting of avoiding bolt to be extracted by punch die.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme to realize: this kind prepares the flat mould of contracting of bolt with one end bent back, include and carry out punch die and to contract flat punch die and the former of bolt, it is characterized in that: described former is provided with bolt positioning hole, described punch die is socketed with punch die cover, the pushing block of red needle and fixing red needle is provided with in described punch die cover, the front end of this red needle is placed in punch die jaws, this jaws front end is provided with the flat step of contracting, also elastic device is provided with in described punch die cover, described elastic device one end connects punch die cover inwall, the other end connects pushing block.
Described elastic device is three springs of socket mutually.
The beneficial effects of the utility model are the flat moulds of the contracting preparing bolt with one end bent back after improving, by arranging three springs be mutually socketed in punch die cover, mutual support, to lead each other, increase the thrust that punch die jaws released by bolt by red needle, solve bolt easily by problem that punch die is extracted.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, detailed description of the invention of the present utility model is described in further detail.
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Drawings illustrate structure of the present utility model, further illustrate its details by reference to the accompanying drawings more below.This prepares the flat mould of contracting of bolt with one end bent back, include the former 2 carrying out punch die 7 that punch die contracts flat and bolt, described former 2 is provided with bolt positioning hole 6, described punch die 7 is socketed with punch die cover 1, be provided with the pushing block 4 of red needle 3 and fixing red needle 3 in described punch die cover 1, corresponding punch die 7 jaws in front end of this red needle 3, this jaws front end is provided with the flat step 8 of contracting, flat for carrying out contracting to bolt, namely the jaws width at step place is less than bolt width; Also be provided with elastic device 5 in described punch die cover 1, described elastic device 5 one end connects punch die and overlaps 1 inwall, and the other end connects pushing block 4; Described elastic device 5 is three springs of socket mutually.During work, bolt is placed in the locating hole 6 of former 2, bolt needs the flat one end of contracting to place towards the jaws direction of punch die 7, when punch die 7 impacts towards former 2 direction, the bolt flat end that contracts enters punch die jaws, red needle moves inward, spring 5 shrinks, and step 8 pairs of bolts of punch die opening part contract, and to carry out contracting flat for flat end, after flat completing of contracting, spring 5 resets, drive red needle 3 bolt to be reduced the staff end and release punch die 7 jaws, wherein three springs 5 be mutually socketed, help mutually, lead each other, increase the thrust to red needle 3, solve bolt easily by problem that punch die is extracted.
In sum, these are only preferred embodiment of the present utility model, be not intended to limit protection domain of the present utility model.All within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
