Description

Buckling die

Technical Field

The utility model relates to a withhold technical field, specifically be a withhold mould.

Background

The buckling die is a pressing die arranged in a die cavity of the buckling die holder, when the buckling die is used, a pipe fitting is placed in the buckling die, a power supply is started, the pressure regulating is carried out, the buckling die is folded, the matched metal joint exerts contraction force through the buckling die of the buckling machine, the metal joint is firmly buckled and pressed on the matched pipe fitting, so that buckling is completed, after buckling is completed, the controller is automatically reversed with the control valve block, the buckling die is kept away, and the pipe fitting can be taken out.

However, the position of the pressing section between the hose and the hard tube is smooth and single in the mold in the prior art, and the mold is easy to be damaged in practical use due to the material characteristics of the hose and the limitation of the buckling structure process,

Aging and oil leakage. Among them, the loose connection at the buckling position of the hose joint leads to oil leakage, which is the most likely problem of the hose assembly.

The utility model 201721646570.3 hose buckling and pressing mould is combined into a hose buckling and pressing mould by arranging a plurality of modules, so that the surfaces of cavities corresponding to the modules can simultaneously and uniformly buckle and press the sleeve on the lining core; however, the extrusion surface of the crimping die is too smooth, so that air still exists between the compressed hose and the compressed hard tube, and the hose still slips and leaks air when in use.

SUMMERY OF THE UTILITY MODEL

In order to solve the above problem, the utility model provides a following technical scheme: a buckling mould comprises a cylindrical mould, wherein the radial section of the cylindrical mould is in a ring shape; the cylindrical mould comprises eight valves with the same shape, and the radial sections of the valves are in a sector shape; still include the mounting hole, the mounting hole set up in on the valve outer wall.

Preferably, the fixing device further comprises a locking screw, and the locking screw is connected with the mounting hole.

Preferably, a row of convex teeth are arranged on the inner wall of the valve, and gaps are reserved among the convex teeth.

Preferably, the teeth are located near one of the valve edges and have a height slightly greater than the other teeth.

Preferably, one end of the locking screw, which is far away from the valve, is provided with a fixing groove.

Compared with the prior art, the beneficial effects of the utility model are as follows:

according to the application, the inner side of each valve of the die is provided with the multiple sections of convex teeth, so that an air gap exists at the compression part of the hose and the hard tube, the pressure intensity during compression is improved, and the tight combination between the hose and the hard tube is ensured; meanwhile, multi-section sealing can be achieved between the hose and the hard pipe after the hose and the hard pipe are subjected to compression molding, and the phenomenon that air leakage occurs in one part of the hose and the hard pipe is prevented, so that the sealing effect of the whole section is influenced.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1-3, a crimping die comprises a cylindrical die 1, wherein the radial section of the cylindrical die 1 is in a ring shape; the cylindrical mold 1 comprises eight valves 2 with the same shape, and the radial sections of the valves 2 are fan-shaped; the valve is characterized by further comprising a mounting hole 3, wherein the mounting hole 3 is formed in the outer wall of the valve 2. The locking device further comprises a locking screw 4, and the locking screw 4 is connected with the mounting hole 3. The mould composed of the eight valves 2 is convenient to install on the withholding machine and is pressed from eight directions to the inner side, so that the pressing force received by the pipe fitting is uniform, and the withholding effect is better.

A row of convex teeth 5 are arranged on the inner wall of the valve 2, and gaps are reserved among the convex teeth 5. The teeth 5 are close to one of the edges of the valve 2 and have a height slightly higher than the other teeth 5. One end of the locking screw 4, which is far away from the valve 2, is provided with a fixing groove 6. Because the buckling and pressing die enables the hose to be tightly wrapped outside the hard pipe by means of pressure, the convex teeth 5 with different gaps can increase the pressure on the pipe fitting. And because a conventional whole section of pressing surface is when producing the gas leakage condition, the hose can break away from with the hard tube under the elastic action of self, consequently multisection dogtooth 5 can make the pressing surface between hose and the hard tube divide into several sections, and has the space between every section of pressing surface, when every section of pressing surface all guarantees the leakproofness, also can ensure that when one of them section of pressing surface leaks gas not influence the leakproofness of other pressing surfaces, improve the withhold effect and the result of use of pipe fitting.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
