Abstract

The invention discloses a flanging mould for a steel sleeve of a steel plate spring. The flanging mould is characterized in that a lug boss is arranged on an upper die and a lower die, respectively; flanging stampings are positioned on the lug bosses; and flanging arc surfaces are arranged at the connecting places of the flanging stampings with the lug bosses. According to the structure, by coordinating the flanging mould with a working platform of a press, both ends of the steel sleeve of the steel plate spring can be flanged; therefore, the flanging quality of the steel sleeve of the steel plate spring is improved and the production efficiency is relatively high.

Description

Leaf spring steel bushing flanging die
Technical field
The present invention relates to a kind of flanging die that is used for automobile leaf spring steel bushing flange.
Technical background
The two ends grasswort lining of light-duty vehicle leaf spring, most of steel bushing turnup structure that adopts, the flange dimensional requirement is strict, and quality is wayward in process of production, and production efficiency is lower, has influenced economic benefit of enterprises.
Summary of the invention
The purpose of this invention is to provide a kind of flanging die that is used for leaf spring steel bushing two ends flange.
To achieve these goals, the present invention is respectively equipped with boss on upper die and lower die, on boss, is provided with flange die and dashes, and is provided with the flange cambered surface at said flange die towards the junction with boss.
Through above setting, the present invention is cooperated with the workbench of forcing press, can realize leaf spring steel bushing two ends flange.Improved the flange quality of leaf spring steel bushing, production efficiency is higher.
Description of drawings
Combine accompanying drawing that the present invention is further specified at present.
Fig. 1 is a structural representation of the present invention.
Among the figure: 1, patrix, 2, counterdie, 3, boss, 4, flange die dashes, 5, the flange cambered surface, 6, grasswort, 7, steel bushing.
The practical implementation method
As shown in Figure 1, the present invention is respectively equipped with boss 3 on patrix 1 and counterdie 2, on boss 3, is provided with flange die and dashes 4, dashes 4 at said flange die and is provided with flange cambered surface 5 with the junction of boss 3.
Through above setting, counterdie 2 of the present invention is placed on the workbench of press, steel bushing 7 inserts in the grasswort 6; And the flange die that an end of steel bushing 7 is inserted in counterdie 2 dashed on 4; With the flange die of patrix 1 dash 4 insert steel bushings 7 the other end, the press upper punch moves down, patrix 1 dashes 4 with flange die on the counterdie 2 and is pressed into simultaneously in the steel bushing 7; Flange cambered surface 5 is the two ends flange of steel bushing 7, and steel bushing 7 and grasswort 6 compressed combine.
