Abstract
The utility model relates to a clamping fixture which comprises two symmetrical mechanical arms referring to the mechanical arm A and the mechanical arm B. Each mechanical arm is composed of a clamping head and a fixing rod. One end of each fixing rod is vertically provided with a fixing hole, each clamping head is arranged at the other end of the corresponding fixing rod, each clamping head and the corresponding rod form a certain angle, a clamping part and a clamping opening are arranged on each clamping head, and each clamping opening is provided with a trapezoid-shaped groove. Moreover, the clamping heads and the fixing rods are integrally formed. Compared with an existing universal fixture, the trapezoid-shaped grooves are formed in the mechanical arms, thus when the mechanical A and the mechanical B are closed and clamped, the clamping opening forms a hexagonal shape, when hexagonal wires are produced, the hexagonal wires of different sizes can be completely positioned, offset of the hexagonal wires is avoided in the process of mold passing, working efficiency is improved, the rejection rate is lowered, namely cost is lowered, and the safety and the stability in the machining process are increased.
Description
Technical field
The utility model relates to a kind of Cold header clamping fixture, relates in particular to a kind of clamping fixture that can clamp special hexagonal wire product.
Background technology
Cold header is a kind of punch process machine in machine-building, when raw material are not made to any change (being mainly the similar processing such as softening or sclerosis), makes forming materials for needs shape (being to be all configured as " step " in general).The steel of manufacturing securing member, connector (as bolt, nut, screw, rivet etc.) use by cold-heading processing method is called cold-forging steel, is commonly called as riveting spiral shell steel.Normally used have quenching and tempering type steel alloy 1, lonneal type structural alloy steel, low-carbon and low-alloy high strength steel, a ferrite-martensite dual-phase steel etc.Cold-heading is to utilize at normal temperatures metal forming.Adopt cold heading technique to manufacture securing member, not only efficiency is high, quality good, and materials are economized, cost is low.But cold heading technique is higher to raw-material quality requirement.For saving cost; general factory is used Cold header processing original paper conventionally to adopt general fixture; existing a kind of universal fixturing as shown in Figure 1; comprise manipulator A and manipulator B; what in the D portion of manipulator, offer is the combination slot of circular and fillet; this fixture is crossed mould and can be offset in the time of the hexagonal wire product of clamping special shape, and causing next step cold pier technique generation deviation to increase error is percent defective, and workman's artificial adjustment also makes that its workload increases, Efficiency Decreasing.
Summary of the invention
For solving the problem that skew can occur when the hexagonal wire product of above-mentioned universal fixturing clamping special shape is crossed mould, the utility model provides a kind of clamping fixture of clamping special shape products that can be more stable.
The technical scheme in the invention for solving the technical problem is: a kind of clamping fixture, comprise two symmetrical manipulators, manipulator A and manipulator B, described manipulator is made up of clamping head, fixed bar, on one end of described fixed bar, vertically offer fixing hole, described clamping head is arranged on the other end of fixed bar, and described clamping head and fixed bar form certain angle, described clamping head is provided with clamping part and clamp port, on described clamp port, offers dovetail groove.
Further, described clamping head, fixed bar are formed in one.
The beneficial effects of the utility model: the utility model is than existing universal fixturing, on its manipulator, offer dovetail groove, manipulator A and manipulator B are in the time that closure clamps thus, its clamp port forms hexagonal and forms, and in the time of production hexagonal wire rod, can locate the hexagonal wire rod of different size completely, make it can not be offset in the time crossing mould, improve operating efficiency, reduced percent defective and reduced cost, increased the safety and stability in process.
Brief description of the drawings
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is the structural representation of existing universal fixturing;
Fig. 2 is structural representation of the present utility model;
Fig. 3 is left view of the present utility model.
Detailed description of the invention
A kind of clamping fixture as shown in Figures 2 and 3, comprise two symmetrical manipulators 1, manipulator A and manipulator B, described manipulator 1 is made up of clamping head 2, fixed bar 3, on one end of described fixed bar 3, vertically offer fixing hole 31, described clamping head 2 is arranged on the other end of fixed bar 3, and described clamping head 2 forms certain angle with fixed bar 3, described clamping head 2 is provided with clamping part 21 and clamp port 22, on described clamp port 22, offers dovetail groove.
Further, described clamping head 2, fixed bar 3 are formed in one.
The utility model is than existing universal fixturing, on its manipulator 1, offer dovetail groove, manipulator A and manipulator B are in the time that closure clamps thus, its clamp port 22 forms hexagonal and forms, and in the time of production hexagonal wire rod, can locate the hexagonal wire rod of different size completely, make it can not be offset in the time crossing mould, improve operating efficiency, reduced percent defective and reduced cost, increased the safety and stability in process.
It is emphasized that, it is more than preferred embodiment of the present utility model, not the utility model is done to any type of restriction in appearance, any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, all still belong in the scope of technical solutions of the utility model.
