Abstract

The utility model belongs to the field of die for processing electric wires and cables, in particular to a retractable die. The die is in a tubular shape, the diameter of an opening which penetrates through two sides of the die is big on two sides and small in center, and the die is formed by halving a plurality of sub blocks, the technical scheme shows that the retractable die changes the traditional closed die into a retractable die, and the retractable die is formed by retracting and fixing a plurality of sub blocks, the retractable die not only can achieve the pressing and winching purposes of cores better, but also can conveniently solve the stubble welding problem during the skein twisting process.

Description

A kind of open-close type mould

Technical field

The utility model belongs to the mould applications of processing electric wire, is specifically related to a kind of open-close type mould.

Background technology

Conductor thread core in the electric wire all adopts the closed type mould to process in the regular stranded and compression of circle in stranded usually, but press stranded formula processing mode for circle, pressing under the coefficient condition with higher especially, adopt the closed type mould to be easy to occur the phenomenon of frequent fracture of wire, so just cause following problem: the one, can't ordinary production, the 2nd, the cable brachycephaly is too many, can't satisfy requirement of client.Though can adopt pressure roller to solve the problem of frequent fracture of wire, need the above pressure roller of twice or twice during work usually, and it is many more to press the high more needed pressure roller quantity of coefficient, therefore causes complex process, and has improved processing cost.

Summary of the invention

The purpose of this utility model provides a kind of open-close type mould, the problem of frequent fracture of wire welding when it can solve cable twist, and manufacturing procedure is simple and processing cost is low.

For achieving the above object, the utility model has adopted following technical scheme: a kind of open-close type mould, and mould is tubular, and the diameter that runs through the opening of mould both sides is that big centre, both sides is little, and described mould is involuted by the experimental process piece.

As shown from the above technical solution, the utility model makes traditional closed type mould into the open-close type mould, described open-close type mould fixedly forms by a few height pieces are involutory, can realize preferably that not only core presses stranded purpose, and can solve the fracture of wire Welding Problems that in the hank knotting process, occurs easily.

Description of drawings

Fig. 2 is the structural representation that removes behind the die sleeve;

Fig. 3 is the A-A cutaway view of Fig. 2.

Embodiment

Shown in Fig. 1～3, a kind of open-close type mould, mould 10 is tubular, and the diameter that runs through the opening of mould 10 both sides is that big centre, both sides is little, and described mould 10 is involuted by experimental process piece 11.

The quantity of described sub-piece 11 can have multiple choices, and as preferred version of the present utility model, described sub-piece 11 is set to two of mutual symmetry, and this setup not only makes up comparatively convenient, and helps later maintenance.

The combination of sub-piece 11 is fixing multiple implementation equally, as preferred version of the present utility model, is provided with pin-and-hole 14 that passes for the location pin and the screw 15 that passes for trip bolt on the described sub-piece 11, as shown in Figure 3.

At first alignment pin is passed pin-and-hole 14 during 11 combinations of sub-piece, thereby make position relative fixed between the sub-piece 11, pass screw 15 by screw again and sub-piece 11 is fixed up tightly.

As the further preferred version of the utility model, as shown in Figure 1, described mould 10 comprises the die body 13 that core rod 12 is set and is set in core rod 12 outsides, and the material of described core rod 12 is the YG8 carbide alloy.

Die body 13 can adopt used 45# material usually, and described core rod 12 adopts the YG8 carbide alloy, can improve the stranded quality and the stranded efficient of cable, helps prolonging life span of mold simultaneously.

As another kind of preferred version of the present utility model, the arranged outside of described mould 10 has and is used for the die sleeve 20 of fastening mould 10.

As shown in Figure 1, described die sleeve 20 is tubbiness, can be square tubbiness or round barrel shape, and the die sleeve 20 of the preferred round barrel shape of the utility model, mould 10 are embedded in the inboard of die sleeve 20, and the end wall of tubbiness die sleeve 20 is provided with opening.

Described die sleeve 20 can increase the degree that closes of mould 10, has improved stranded quality and the efficient of this open-close type mould core further, helps the utility model to carry out work with security and stability.

Fixed form between die sleeve 20 and the mould 10 also has multiple implementation method, as preferred version of the present utility model, as shown in Figure 1, it circumferentially is provided with bolt hole equably the sidewall upper edge of the ring-type of described die sleeve 20, and bolt 30 passes bolt hole and is resisted against tightly on the mould 10.

Adopt the mode of bolt comparatively simple, be easy to make up and be convenient to fix.

Below in conjunction with accompanying drawing the utility model is further described:

By shown in Figure 3 two pins are embedded mould 10 by pin-and-hole 14, make last half son's piece 11 and following half son's piece 11 of mould 10 involutory, hammer into with mould 10 fixations by screw 15 with two screws again, then as shown in Figure 1, at the outside of mould 10 cover Upper Die-sleeve 20, and the fastening degree of passing die sleeve 20 further increase moulds 10 with four bolts 30.

After mould 10 assemblings fix, closed type mould as routine carries out threading, band line and stranded, if there is apparent in view cut stranded core outside, should take off die sleeve 20 and readjust screw, not too obviously can until cut, it should be noted that slight cut allows, first-class again again die sleeve 20, fixing with bolt 30 can normal boot-strap production.

If occur the situation of fracture of wire when producing, can take apart a die 10 with reference to aforesaid reverse order, the monofilament of the good broken end of welding, re-assemblied mould 10 at weld according to preceding method then, simultaneously in conjunction with other aid, mould 10 is rushed to place, thread reaming machine separated time hole, can carry out ordinary production.
