Abstract

The invention discloses a process flow for machining a lower punching die. A process head is reserved in the process of machining the lower punching die, so that deformation produced at the relatively thin position of the wall of the die due to stress in the machining process is effectively reduced, waste produced by scrapping due to high deformation in the machining process of the die is avoided, the machining precision of the die is greatly improved, the production efficiency can be effectively improved, and the waste is reduced.

Description

A kind of punch die tool processing process down

Technical field

The present invention relates to a kind of mould, particularly relate to a kind of processing process of punch die tool down.

Background technology

Existing mold production process is generally following: car → mill mark → numerical control marking → brill → heat treatment → roughly grind → be careful silk; Line cutting → electric spark → silk → the electric spark of being careful → bedding-in; The leading portion operation has car respectively, bores, mills and grinds, back segment operation electric spark, numerical control is milled and soon, slow line cutting, grinding etc.After accomplishing complicated curved surface and aperture operation, the depth of parallelism of face shape requires to reach 10 ~ 5 μ m, and the required precision of aperture is controlled to be 1 ~ 5 μ m, to guarantee the quality of mould.At used drift material is the high chromium cold work tool steel of SLD high abrasion; When heat treatment is main with application of vacuum; To some mould; Such as the mould that once dashes under three on the flange type one; Wall ratio is thinner in the platelet position for conventional structure, in line cutting processing because of the influence that is subjected to the stress effect has the phenomenon of distortion through regular meeting, thereby cause die deformation to be scrapped; Have a strong impact on the efficient of production, also cause the waste of resource.

Summary of the invention

In order to overcome the deficiency of prior art, the present invention proposes a kind of down punch die tool processing process, in process, keep a technique head, to avoid or to alleviate the distortion of drift in process in the relatively thinner platelet position of mold wall thickness.

The technical solution adopted for the present invention to solve the technical problems is:

A kind of punch die tool processing process down, it comprises following processing step:

1) blanking: the high chromium cold work tool steel of the high abrasion blank of selecting to be of a size of ф 100*147mm is processed;

2) turner preface: blank is carried out the turner preface; Process the profile of mould by drawing; And at mould ф 80*5 place outer wall to remain with thickness be that 3 ~ 4mm, width are the technique head of 2 ~ 5mm; The ф 80*5 place of following punch die tool is the thin platelet place of wall thickness, keeps technique head and can prevent effectively that platelet is in the following manufacturing procedure and deform;

3) line: adopt scoring tool underlining Working position and shape on mould by drawing;

4) boring: adopted drilling machine on mould, to leave fabrication hole by the underlining in a last step;

5) heat treatment: mould is heat-treated, make the hardness of mould reach Rockwell hardness 57-59;

6) line cutting roughing: the requirement with reference to drawing is carried out line cutting roughing to mould, and the monolateral allowance for finish that stays 0.5 ± 0.10mm prevents that mould is out of shape because of machining stress is excessive;

7) spark machined; Requirement with reference to drawing is carried out spark machined to mould; Erosion removes the allowance that a last operation stays; Through spark machined the size of drawing requirement is arrived in mould roughing, and significantly reduce the stress of process, reduce the distortion of mould and the situation of damage;

8) line cutting fine finishining: mould is carried out line cutting fine finishining, following punch die tool accurately is worked into the concrete size of design drawing requirement;

9) turner preface: the following punch die tool to after the line cutting fine finishining carries out the turner preface, and the technique head of reserving is removed;

10) mill: the size that each surfacing of mould of accomplishing cutting is arrived drawing requirement;

11) electric spark: the size that arrives drawing requirement through the end face each several part of spark machined mold and punching head;

12) grind: grind on the surface to mould, and the roughness that makes die surface is accomplished processing less than 0.1mm.

The invention has the beneficial effects as follows: the following punch die tool that adopts this technological process to process; Owing in the turner preface of beginning, kept technique head; The thin platelet position of wall thickness is in the process of following process has avoided moderate finite deformation; And the concentricity that can make the mould that processes be controlled at less than 0.015mm among a small circle in; Improved the machining accuracy of mould greatly, avoided mould in process, to scrap the wasting phenomenon that causes because of distortion.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the present invention is further specified.

Fig. 1 is the mould structure sketch map that the present invention keeps technique head.

The specific embodiment

With reference to Fig. 1, the invention discloses a kind of punch die tool processing process down, adopt the step of wherein a kind of punch die tool down of technological process processing of the present invention following: 1) blanking: the SLD tool steel blank of selecting to be of a size of ф 100*147 is processed; 2) turner preface: blank is carried out the turner preface; Process the profile of mould 1 by drawing, keep technique head 11 at ф 80*5 place by technological requirement, wherein the thickness of technique head 11 is 3 ~ 4mm; Width is 2 ~ 5mm, and technological parameter processing on the design drawing is pressed in all the other places; 3) line: underlining Working position and shape on mould 1 by drawing; 4) boring: by drawing and each fabrication hole of mould 1 processing technology requirement processing; 5) heat treatment: mould 1 is heat-treated; 6) line cutting roughing: the requirement with reference to drawing is carried out line cutting roughing, the monolateral allowance for finish that stays 0.5+0.10 to mould 1 and two Xia Chong cooperation places; 7) spark machined: mould 1 is carried out spark machined, and erosion removes the allowance that a last operation is reserved; 8) line cutting fine finishining: mould 1 is carried out line cutting fine finishining, mould 1 accurately is worked into the concrete size of design drawing requirement; 9) turner preface: the mould 1 to after the line cutting fine finishining carries out the turner preface, and the technique head of reserving 11 is removed; 10) mill: will accomplish the size of mould 1 each surfacing of cutting to drawing requirement; 11) electric spark: the size that arrives drawing requirement through the end face each several part of electrical spark working tool and mould 1 drift; 12) grind: grind on the surface to mould 1, and the roughness that makes mould 1 surface is accomplished processing less than 0.1mm.

The following punch die tool that adopts this technological process to process; Owing in the turner preface of beginning, kept technique head 11; The thin platelet position of mould 1 wall thickness is in the process of following process has avoided moderate finite deformation; And the concentricity that can make the mould 1 that processes be controlled at less than 0.015mm among a small circle in; Improved the machining accuracy of mould 1 greatly, avoided mould 1 in process, to scrap the wasting phenomenon that causes because of distortion.
