CN104523131A - Novel stockpot manufacturing process - Google Patents

Abstract

The invention discloses a novel stockpot manufacturing process which is different from a traditional stockpot manufacturing process. The outer surface of the bottom of a stockpot is corrugated in the drawing forming process of the stockpot, and an opening of a stockpot body is shaped in a shape similar to a right angle through a forging imitative method. The novel stockpot manufacturing process breaks through a traditional thick material forging corrugating thought, forming process parameters are accurately analyzed, the mold design is special, and the outer bottom of the stockpot is corrugated, so that the problem that no obvious boundary is generated between the stockpot bottom plane and the stockpot bottom angle r is solved, and the method breaks through the restraint of aluminum cooker stockpot body material thickness on the stockpot bottom corrugating process; in addition, the stockpot body manufactured through the process is adopted, the opening of the stockpot body is shaped in the shape similar to the right angle through the forging imitative method, and the problem that a cover slides out of the stockpot body from the opening of the stockpot body is effectively solved.

Description

A kind of novel slaughterhouse manufacture craft

Technical field

The present invention relates to cooker production technology, be specifically related to a kind of novel slaughterhouse manufacture craft.

Background technology

Traditional drawing straight flange aluminum cookware, because of the impact that pot body material is thick, form larger fillet at pot body oral area, when coordinating with lid, lid very easily skids off a pot body from pot mouth.In addition, traditional aluminum products drawing cooker, the bottom of a pan plane and r angle, the bottom of a pan not comparatively obvious line of demarcation, this phenomenon brings larger difficulty to the rear operation of pot body (at the bottom of sand, segmented anodes oxidation etc.) process.

Summary of the invention

In order to solve the problem, the object of this invention is to provide a kind of novel slaughterhouse manufacture craft, it installs firmly, difficult drop-off.

The technical solution adopted in the present invention is:

A kind of novel slaughterhouse manufacture craft, comprises the following steps:

A, employing cupping tool carry out drawing to metal disk, and obtain the blank of pan, die has wherein been provided with the groove of level, after drawing, pan bottom outer surface plays level, and pan oral area forms larger round-corner transition after drawing;

B, the pan blank that step a obtains is put into another mould carry out thinning process, make pot body directly as being thinned to same thickness by further stretching, pot body extends further to pan oral area, and the round-corner transition of pan oral area is diminished;

C, the pan semi-finished product that step b obtains are carried out the finishing of car limit;

D, the pan semi-finished product that step c obtains are put into forge die, adopt the mode of forging and stamping to suppress pan, complete pressure basic skill or training and do, the fillet of pot body oral area is shaped as right angle after imitative forging and stamping simultaneously;

E, the pan semi-finished product that steps d obtains are carried out the finishing of car limit;

F, cleaning pan.

The invention has the beneficial effects as follows:

The thick material that present invention process breaks traditions has forged and pressed level thinking, by accurately analyzing molding technique parameter, unique Design of Dies, level has been increased at pot body outer bottom, not only solve the bottom of a pan plane and r angle, the bottom of a pan not comparatively obvious marginal problem, and breach the thick restriction the bottom of a pan being played to grade technique of aluminum cookware pot body material; In addition, adopt the pot body that present invention process makes, by the method for imitative forging and stamping, pot body oral area is shaped into approximate right angle shape, efficiently solves lid skids off pot body phenomenon from pot mouth.

Accompanying drawing explanation

Below in conjunction with the drawings and specific embodiments, the present invention is further detailed explanation.

Fig. 1 is the structural representation of drawing step when carrying out and the pan blank obtained;

Fig. 2 is the structural representation of step b when carrying out and the pan semi-finished product obtained;

Fig. 3 is the structural representation of steps d when carrying out and the pan semi-finished product obtained.

Detailed description of the invention

Referring to figs. 1 through Fig. 3, the invention provides a kind of novel slaughterhouse manufacture craft, comprise step a to step f, concrete flow process is as follows: a, employing cupping tool carry out drawing to metal disk, obtain the blank of pan, die has wherein been provided with the groove of level, after drawing, pan bottom outer surface plays level, and pan oral area forms larger round-corner transition after drawing; B, the pan blank that step a obtains is put into another mould carry out thinning process, make pot body directly as being thinned to same thickness by further stretching, pot body extends further to pan oral area, and the round-corner transition of pan oral area is diminished; C, the pan semi-finished product that step b obtains are carried out the finishing of car limit; D, the pan semi-finished product that step c obtains are put into forge die, adopt the mode of forging and stamping to suppress pan, complete pressure basic skill or training and do, the fillet of pot body oral area is shaped as right angle after imitative forging and stamping simultaneously; E, the pan semi-finished product that steps d obtains are carried out the finishing of car limit; F, cleaning pan.

The thick material that present invention process breaks traditions has forged and pressed level thinking, by accurately analyzing molding technique parameter, unique Design of Dies, level has been increased at pot body outer bottom, not only solve the bottom of a pan plane and r angle, the bottom of a pan not comparatively obvious marginal problem, and breach the thick restriction the bottom of a pan being played to grade technique of aluminum cookware pot body material; In addition, adopt the pot body that present invention process makes, by the method for imitative forging and stamping, pot body oral area is shaped into approximate right angle shape, efficiently solves lid skids off pot body phenomenon from pot mouth.

These are only preferred embodiments of the present invention, as long as the technical scheme realizing the object of the invention with basic same approach all belongs within protection scope of the present invention.
