Abstract

The utility model discloses an ausform composite mould, belonging to the mould technical-field, comprising the matching concave mould and convex mould. At least one cooling water chamber is respectively set in the concave mould and convex mould. The water inlet and outlet linking the corresponding cooling chamber are set on the surfaces of concave mould and convex mould. During its running, the cooling water enters through the water inlet and is guided out form the outlet. When the cooling water flows through the cooling chamber the mould and work pieces can be cooled. Before the work piece form into a shape, you need to heat the work piece and the heated pieces are easy to form into a shape in the mould. While the work piece is forming into shape, they are cooled and form into the desired products. Because the forming and heating treatment are done at the same time, the work pieces de-shape less and have a high precision. The utility model fits the process of producing thin metal pieces, such as film spring, brake disk, saw blade and milling cutter.

Description

A kind of thermomechanical treatment composite die
Technical field
The utility model relates to a kind of mould, particularly a kind of mould of thin type workpiece.
Background technology
In the prior art, produce thin type workpiece such as diaphragm spring, brake disc, saw blade, milling cutter, need to adopt mould molding, this mould mainly is made up of die and punch, cooperatively interact between die and the punch, can be on forcing press with the workpiece punch forming, the workpiece after the moulding need take off and heat-treat; Its weak point is: when heat treatment, cause workpiece deformation easily, lose round, off-centre, not parallel, influence the quality of product.
The utility model content
The purpose of this utility model provides a kind of thermomechanical treatment composite die, makes mould in moulding, can also heat-treat workpiece, to obtain precision height, the little high-precision product of deformation.
The purpose of this utility model is achieved in that a kind of thermomechanical treatment composite die, comprise the die and the punch that can cooperatively interact, be respectively equipped with at least one cooling water cavity in described die and the body of punch, die and convex mould surface are provided with water inlet and the delivery port of connecting corresponding cooling water cavity.
During the utility model work, feed cooling water at water inlet, and draw from delivery port, cooling water is through cooling water cavity the time, can be with the work-piece cools on mould and the mould, before Workpiece shaping, need workpiece is heated, workpiece easier moulding on mould of heat, in moulding, workpiece is cooled, form satisfactory product, because moulding and heat treatment are carried out simultaneously, workpiece deformation is little, the precision height, the utility model is fit to be applied in makes the thin type metalwork, as diaphragm spring, brake disc, saw blade, milling cutter etc.
For making things convenient for the processing of the cooling water cavity on die and the punch, described die and punch are formed by connecting through bolt by two bodies up and down respectively, are provided with sealing ring between two bodies up and down.The setting of sealing ring is to leak in order to prevent.
Be the convenient location and the demoulding, described punch center is provided with cylindrical cavity, is provided with the location core in the cavity, is provided with back-moving spring between core lower end, location and the cavity bottom.Add man-hour, the blank of workpiece is nested with on the core of location, can prevent the workpiece skew, made things convenient for processing, after punch forming, die and punch break away from, and back-moving spring is separated workpiece jack-up and punch, is convenient to the demoulding.
For strengthening the cooling effect in the heat treatment process, be provided with dividing plate in the cooling water cavity in described die and the punch, dividing plate is provided with the aquaporin that runs through dividing plate.This technical scheme can make cooling water flow more in order, reduces the stagnant area, can in time take away heat, and the workpiece each several part is evenly cooled off to obtain good thermal effectiveness.
Description of drawings
Fig. 1 is the utility model structural representation;
The specific embodiment
As figure, for making the thermomechanical treatment composite die of diaphragm spring 6, comprise the die 9 and the punch that can cooperatively interact, the working face that die 9 and punch match is tapered, be respectively equipped with cooling water cavity 1 in die 9 and the body of punch, die 9 and convex mould surface are provided with water inlet 3 and the delivery port 5 of connecting corresponding cooling water cavity 1, be provided with dividing plate 10 in the cooling water cavity 1 in die 9 and the punch, dividing plate 10 can be connected as a single entity with die 9 or punch, dividing plate 10 is provided with the aquaporin 11 that runs through dividing plate 10, dividing plate 10 has the reinforcement mould strength, isolates the effect of cooling water cavity 1 simultaneously; Die 9 and punch are formed by connecting through bolt by two bodies up and down respectively, are provided with sealing ring 2 up and down between two bodies; The punch center is provided with cylindrical cavity, is provided with location core 7 in the cavity, is provided with back-moving spring 6 between core 7 lower ends, location and the cavity bottom.
During the utility model work, feed cooling water at water inlet 3, through each compartment, draw from delivery port 5 then, cooling water can recycle by water pump, pond, and cooling water can be with the work-piece cools on mould and the mould through cooling water cavity 1 time; Add man-hour, the workpiece blank 8 that is heated to uniform temperature in advance is nested with on the core 7 of location, upper and lower mould matched moulds then, workpiece is pressed into dish, and in moulding, workpiece is cooled, form satisfactory product, after punch forming, die 9 and punch break away from, and back-moving spring 6 is separated workpiece jack-up and punch.
