Abstract
The invention discloses a kind of electric power connector contact head heat treatment bulging mould, this mould comprises urceolus and core, this urceolus comprises the ladder endoporus be made up of the circular hole that two radiuses are different, described core comprises integrated mandrel portion and ceiling plate portion, this mandrel portion is cylindric, and this ceiling plate portion is arranged at an end in mandrel portion; The other end in described mandrel portion is provided with guide part, and the external diameter of described guide part is less than the internal diameter of electric power connector contact head, and the size in mandrel portion is greater than the internal diameter of electric power connector contact head, the small sircle hole of described mandrel portion and ladder endoporus closely cooperate and; The big hole of ladder endoporus is greater than the external diameter of electric power connector contact head, and the gap before the big hole of described mandrel portion and ladder endoporus constitutes the swollen mouth space of contact head.This bulging mould can supporting with contact head together with heat treatment, thus accurately control the size of the swollen mouth in contact head end, improve the qualification rate of product.
Description
Technical field
The present invention relates to a kind of bulging mould, refer to a kind of electric power connector contact head heat treatment bulging mould especially.
Background technology
Electric power connector contact head is the axial workpiece with centre bore, and the two ends of contact head are provided with the strip gab of some axis, and this strip gab is to make the swollen mouth in the two ends of contact head, is convenient to electric power connector contact head and the mutual grafting of miscellaneous part; The contact head offering the strip gab of some axis needs to heat, and during heat treatment, strip gab there will be heat expansion distortion, thus realizes swollen mouth.Because current contact head is heat treated under free state, the shape of swollen mouth differs, the size of swollen mouth and amplitude can not accurately control, can only control the heat treated time controls swollen mouth size, so another object heat treated improves the material hardness of contact head, when ensureing enough heat treatment times to reach material regulation hardness, swollen mouth size is then uncontrollable, and the qualification rate of product is reduced.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of electric power connector contact head heat treatment bulging mould, this bulging mould can supporting with contact head together with heat treatment, thus accurately control the size of the swollen mouth in contact head end, improve the qualification rate of product.
For solving the problems of the technologies described above, technical scheme of the present invention is: a kind of electric power connector contact head heat treatment bulging mould, this mould comprises urceolus and core, this urceolus comprises the ladder endoporus be made up of the circular hole that two radiuses are different, described core comprises integrated mandrel portion and ceiling plate portion, this mandrel portion is cylindric, and this ceiling plate portion is arranged at an end in mandrel portion; The other end in described mandrel portion is provided with guide part, and the external diameter of described guide part is less than the internal diameter of electric power connector contact head, and the size in mandrel portion is greater than the internal diameter of electric power connector contact head, the small sircle hole of described mandrel portion and ladder endoporus closely cooperate and; The big hole of ladder endoporus is greater than the external diameter of electric power connector contact head, and the gap before the big hole of described mandrel portion and ladder endoporus constitutes the swollen mouth space of contact head.
As the preferred scheme of one, described guide part is the guide part of circular cone table top.
As the preferred scheme of another kind, described guide part comprises frustum of a cone portion and cylindrical portion, and cylindrical portion connects the miner diameter end in frustum of a cone portion, and mandrel portion is connected to the bigger diameter end in frustum of a cone portion.
As the preferred scheme of another kind, the endoporus of the big hole of described urceolus is along being provided with guiding surface.
After have employed technique scheme, effect of the present invention is: owing to have employed this bulging mould, bulging mould is inserted in the two ends of connector contact head, core inserts in the endoporus of contact head, and urceolus is enclosed within the outside of contact head, and the gap between urceolus and contact head is then the maximum magnitude allowing contact alliteration mouth, like this, the swollen mouth size in end of this contact head is just very accurate, can guarantee that enough heat treatment times are to increase the hardness of product, improve the qualification rate of product.
Again because the endoporus of the big hole of described urceolus is along being provided with guiding surface, being convenient to urceolus and being inserted in contact head end.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the structure sectional view of the embodiment of the present invention and contact head;
Fig. 2 is the structure sectional view of the embodiment of the present invention;
In accompanying drawing: 1. contact head; 2. bulging mould; 21. urceolus; 211. guiding surface; 22. cores; . ceiling plate portion; 222. mandrel portions; 223. guide part.
Detailed description of the invention
Below by specific embodiment, the present invention is described in further detail.
As shown in Figure 1, 2, a kind of electric power connector contact head 1 heat treatment bulging mould 2, this mould comprises urceolus 21 and core 22, this urceolus 21 comprises the ladder endoporus be made up of the circular hole that two radiuses are different, described core 22 comprises integrated mandrel portion 222 and ceiling plate portion 221, this mandrel portion 222 is cylindric, and this ceiling plate portion 221 is arranged at an end in mandrel portion 222; The other end in described mandrel portion 222 is provided with guide part 223, the external diameter of described guide part 223 is less than the internal diameter of electric power connector contact head 1, the size in mandrel portion 222 is greater than the internal diameter of electric power connector contact head 1, described mandrel portion 222 and the small sircle hole of ladder endoporus closely cooperate and; The big hole of ladder endoporus is greater than the external diameter of electric power connector contact head 1, and the gap before the big hole of described mandrel portion 222 and ladder endoporus constitutes the swollen mouth space of contact head 1.This is swollen mouth space constraint amplitude of deformation at contact head 1 two ends, thus ensure that the swollen mouth size of contact head 1 is within the scope required.
Wherein, the form of this guide part 223 has multiple, and such as, guide part 223 is the guide part 223 of circular cone table top.Or described in Fig. 1 or 2, described guide part 223 comprises frustum of a cone portion and cylindrical portion, cylindrical portion connects the miner diameter end in frustum of a cone portion, and mandrel portion 222 is connected to the bigger diameter end in frustum of a cone portion.
And the endoporus of the big hole of described urceolus 21 is along being provided with guiding surface 211.The termination external diameter that this guiding surface 211 is convenient to contact head 1 two ends inserts in big hole.
Comparatively speaking, as long as i.e., ladder endoporus, so inherently comprise a big hole and a small sircle hole, therefore, this description is clearly for big hole described in the present invention and small sircle hole.
Two bulging moulds 2 are inserted into the two ends of contact head 1, are then heat-treated, so the swollen mouth at contact head 1 two ends is retrained by bulging mould 2, thus the size after swollen mouth is met the demands, and improves the qualification rate of product.
