Description

Double-waist-line-shaped compression mould

Technical Field

The utility model relates to a mould structural design field specifically is a two waist line shapes receive press mould, is applicable to the receipts pressure that "two waist line shapes" hydraulic pressure connect.

Background

At present, the closing die configured on a buckling press in the market closes the hydraulic joint in a linear form, the closing and pressing form does not conform to the double-waist line form specified by a new design process drawing, and the closing and pressing die cannot be applied to the production of double-waist line-shaped hydraulic joint products. If the compression form in the existing 'linear' compression mould is simply changed into 'double-waist linear', we find that the existing compression mould is in 'linear' form, the deviation of mould positioning can not affect the compression form, so the existing compression mould lacks a positioning functional part, and the accurate compression is difficult after the compression form is changed into 'double-waist linear'.

SUMMERY OF THE UTILITY MODEL

For solving the current situation that current withhold machine receipts pressing die can not satisfy the production demand, the utility model provides a two stringness shape receipts pressing die, this mould not only makes things convenient for clamping, practicality, still can once fix a position, has effectively improved product production efficiency and quality, has thoroughly solved product production processing demand, has increased the product production form.

The technical scheme of the utility model is that:

the double-waist-line-shaped compression mold is characterized in that: comprises an eight-petal mould compression mould, a positioning thimble and a positioning sheet;

the inner cavity closing part of each split mold in the eight-split mold pressing mold is provided with a double-waist line shape with the same position in the axial direction; the double-waist line shape is consistent with the compression form of the compression joint to be compressed;

a positioning thimble is fixed on the outer side surface of each split mold in the eight-split mold compression mold in a threaded manner; the positioning ejector pins can be matched with the mounting holes in the main die of the buckling press, and each split die in the eight-split die compression die is fixedly mounted in the main die of the buckling press;

the rear end face of each valve in the eight-valve mould pressing and withdrawing mould is provided with a threaded hole for fixing a positioning sheet; the positioning sheet is radially fixed at the rear end of one of the petals in a threaded manner; and one end of the positioning sheet, which faces the center of the eight-petal mold compression mold, is used for being matched with a step surface of the compression joint to be contracted to axially position the compression joint to be contracted.

Further preferred scheme, two waist line shape receipts press mold, its characterized in that: and the threaded holes on the rear end surface of each split mold in the eight-split mold compression mold are positioned on the same circumference.

Further preferred scheme, two waist line shape receipts press mold, its characterized in that: the spacer orientation eight lamella moulds receive the one end at moulding-die center and have the arc breach, the arc breach can axial support and treat the step face of binding off and receive the crimping head, realizes treating binding off and receive crimping head axial positioning.

Advantageous effects

The utility model discloses structural design is simple, reasonable, has not only reached technology, has satisfied the customer demand, has still improved product work efficiency, has increased the product processing type, and the most important product quality has obtained the improvement.

Additional aspects and advantages of the invention will be set forth in part in the description which follows and, in part, will be obvious from the description, or may be learned by practice of the invention.

Detailed Description

The following detailed description of embodiments of the invention is intended to be illustrative, and not to be construed as limiting the invention.

The double-waist-line-shaped compression mold in the embodiment comprises an eight-split mold compression mold 1, a positioning thimble 2 and a positioning sheet 3;

the inner cavity closing part of each split mold in the eight-split mold pressing mold is provided with a double-waist line shape with the same position in the axial direction; the shape of the double waistline is consistent with the compression form of the compression joint 4 to be compressed.

A positioning thimble is fixed on the outer side surface of each split mold in the eight-split mold compression mold in a threaded manner; the positioning ejector pins can be matched with the mounting holes in the main die of the buckling press, and each split die in the eight-split die pressing and withdrawing die is fixedly mounted in the main die of the buckling press, so that the die is convenient to replace and mount, and the operation is simple.

The rear end face of each split mold in the eight-split mold compression mold is provided with a threaded hole for fixing the positioning sheet, and the threaded holes in the rear end face of each split mold in the eight-split mold compression mold are located on the same circumference. The positioning sheet is radially fixed at the rear end of one of the petals in a threaded manner; just the spacer orientation the one end at eight lamella moulds receipts moulding-die centers has the arc breach, and the arc breach can axial support the step face of waiting to close up to receive the pressure head, realizes waiting to close up to receive the pressure head axial positioning, not only conveniently waits to close up to receive the location of pressure head and receive the pressure, still can improve work efficiency, guarantees every product and receives the pressure quality.

When in use, the contact surface of the eight-petal mold compression mold and the main mold is properly cleaned to avoid damaging the surface; then, pulling a dragging thimble 6 on the master mold by using a loading and unloading tool 5, inserting a positioning thimble of the mold into the master mold, enabling the mold number to always face an operator, unlocking the dragging thimble after the positioning thimble of the mold is locked at the position of the mould, and finishing the installation of the single-piece mold; the integrally installed die is directly and perfectly seated in the main die without loosening. The rear end of each compression mold of the eight-piece mold is provided with a threaded hole, the positioning sheet is arranged in the threaded hole through a screw, and when the compression joint penetrates into the mold cavity to push the positioning sheet at the front end, an operator can operate the crimping machine to crimp the mold according to a set size value, and does not need to visually observe the mold cavity every time and then crimp the mold cavity again, so that the working efficiency can be greatly improved, and the consistency of the compression quality of each product is ensured.

Although embodiments of the present invention have been shown and described, it is to be understood that the above embodiments are exemplary and should not be construed as limiting the present invention, and that changes, modifications, substitutions and alterations can be made to the above embodiments by those of ordinary skill in the art without departing from the principles and spirit of the present invention.
