Abstract

The utility model discloses a flaring die for a steel wheel rim of a passenger car, which comprises an upper die holder, a lower die holder, an upper die core, a lower die core, an upper die core pressing block, a lower die core pressing block, two positioning rings, an upper die insert block and a lower die insert block, wherein two sides of the die holders are respectively connected with the corresponding guide sleeves through guide poles; the upper and the lower die cores are respectively connected with the inner side surfaces of the upper die holder and the lower die holder; the upper die core pressing block and the lower die core pressing block are respectively connected with the upper die core and the lower die core and form grooves with the outer side surfaces of the upper die core and the lower die core; the two positioning rings are respectively arranged at the peripheries of the upper die core and the lower die core and connected with the upper die holder and the lower die holder; and the upper die insert block and the lower die insert block are respectively embedded in grooves on the outer side surfaces of the upper die core and the lower die core, and the outer side surfaces of the insert blocks are conical surfaces. The flaring die adopts the modular design and simplifies the development process of product process: die carries, the die cores, the insert blocks, the pressing blocks and the positioning rings are designed by modules; and the assembly is carried out by modules, and the production preparation time is reduced. The flaring die realizes the rim flaring, ensures the rim forming quality and reduces the material rejection rate.

Description

Passenger car steel wheel rim enlarging mould

Technical field

The utility model belongs to passenger car steel wheel manufacturing technology field, particularly passenger car steel wheel rim enlarging mould.

Background technology

Enlarging is the important procedure in the steel wheel rim molding procedure, and is closely related with wheel rim final molding quality, also influences the scrappage of material.

Summary of the invention

The purpose of this utility model is to design a kind of passenger car steel wheel rim enlarging mould, realizes the wheel rim enlarging, guarantees the wheel rim Forming Quality, reduces the material scrappage.

For achieving the above object, the technical solution of the utility model is,

Passenger car steel wheel rim enlarging mould, it comprises, upper and lower die holder, both sides link to each other by guide pillar and corresponding guide pin bushing respectively; Upper and lower core rod is connected to upper and lower die holder medial surface; Upper and lower core rod briquetting is connected in upper and lower core rod by screw, with the lateral surface formation groove of upper and lower core rod; Two centring rings are arranged at upper and lower core rod periphery respectively, are connected in upper and lower die holder; Upper and lower mould is inserted, and is embedded at the groove of upper and lower core rod lateral surface respectively, and this lateral surface of inserting is the conical surface.

The characteristics of the utility model wheel rim enlarging mould are:

1) modularized design, simplify product process exploitation process: mould bases, core rod, insert, briquetting and the design of centring ring sub-module, concentrate on according to the product process requirements and to insert and the designing and developing of centring ring, save the development time; 2) insert material is the particular mold steel, the consumption of the formula of inserting design optimization material, the development cost of reduction mould; 3) sub-module assembling is produced time and is reduced; 4) mould improves the adaptability of product, and a pair is inserted and can be adapted to 2 kinds or more products.

Description of drawings

Fig. 1 is the structural representation of the utility model wheel rim enlarging mould.

The specific embodiment

Referring to Fig. 1, passenger car steel wheel rim enlarging mould of the present utility model, it comprises, upper and lower die holder 1,2, both sides respectively by guide pillar 3,3 ' and corresponding guide pin bushing 4,4 ' link to each other; Upper and lower core rod 5,6 is connected in upper and lower die holder 1,2 medial surfaces by screw respectively; Upper and lower

core rod briquetting

52,62 is connected in upper and lower core rod 5,6 by screw, with the lateral

surface formation groove

51,61 of upper and lower core rod 5,6; Two centring rings 7,8 are arranged at upper and lower core rod 5,6 peripheries respectively, are connected in upper and lower die holder 1,2 by screw; Upper and lower mould inserts 9,10, is embedded at the

groove

51,61 of upper and lower core rod lateral surface respectively, and this lateral surface 91,101 of inserting is the conical surface.

The course of work is as follows:

To enclose circle wheel rim cover is put in counterdie and inserts 10; Start press, patrix is descending with press, and patrix is inserted and 9 entered circle circle wheel rim 11 inside; It is descending that patrix continues, upper and lower mould insert 9,10 with circle circle wheel rim 11 in circle circle applyings up and down; Subsequently, the applying position is subjected to the effect of axial enlarging pulling force to begin distortion, is deformed into the conical surface with upper and lower mould 9, the 10 applying lines of inserting; Circle circle wheel rim 11 intermediate cylindricals partly transmit pressure; Centring ring was 7,8 o'clock about lower edge all contacted in the wheel rim enlarging, and patrix reaches extreme limit of travel; The press back resetting, the circle circle wheel rim 11 after the taking-up enlarging.
