Description

Stamping production line for large supporting sleeve of automobile chassis

Technical Field

The utility model relates to a vehicle chassis supports cover preparation technical field greatly, in particular to vehicle chassis supports cover stamping production line greatly.

Background

At present, each process of the large support sleeve stamping process of the automobile chassis is independently completed, and the process is shown in figure 1 and comprises a blanking process, a stretching process, a shrinking process, a shaping process and a punching process. The blanking process is to stamp a round plate 1 on the plate by using a blanking die, the stretching process is to stretch the round plate 1 into a bowl-shaped part 2 by using a stretching film, the shrinking process is to shrink the bowl-shaped part 2 into a small-diameter cylinder 3 and a large-diameter ball-table-shaped bowl opening 3a by using a shrinking die, the shaping process is to shape the large-diameter ball-table-shaped bowl opening 3a into a flange edge 4 by using a shaping die, and the punching process is to stamp a plurality of holes 4a on the flange edge 4 by using a punching die. The flange edge 4 is easy to crack in the shaping process in the processing mode, so that the rejection rate is high.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that the processing mode to current chassis supports cover greatly exists problem and provide a chassis supports cover stamping production line greatly.

The utility model discloses the technical problem that will solve can realize through following technical scheme:

a stamping production line for large support sleeves of automobile chassis comprises a blanking station, a first stretching station, a second stretching station, a trimming station, a first shaping station, a second shaping station, a punching station, a separating station and a waste cutting station, wherein a blanking die, a first stretching die, a second stretching die, a first shaping die, a second shaping die, a punching station, a separating station and a waste cutting station are respectively arranged on the blanking station, the first stretching station, the second stretching station, the trimming station, the first shaping station, the second shaping station, the punching station, the separating station and the waste cutting station; when the belt material for preparing the large support sleeve of the automobile chassis passes through the blanking station, the first stretching station, the second stretching station, the trimming station, the first shaping station, the second shaping station, the punching station, the separating station and the waste cutting station, intermediate parts obtained by the blanking station, the first stretching station, the second shaping station, the trimming station, the punching station and the separating station are not separated from the belt material for preparing the large support sleeve of the automobile chassis until the waste cutting station separates from the belt material for preparing the large support sleeve of the automobile chassis.

Since the technical scheme is used, the utility model discloses can realize that vehicle chassis supports cover serialization production greatly, simultaneously in first tensile station and the tensile station of second, the tensile intermediate part of institute does not have and is used for preparing the strip separation that vehicle chassis supported the cover greatly, and stress is evenly separated when making follow-up plastic, and the fracture defective rate reduces by a wide margin.

Drawings

Fig. 1 is a schematic view of a processing procedure of a large support sleeve of an existing automobile chassis.

Fig. 2 is the utility model discloses chassis supports cover stamping line's principle sketch map greatly.

Detailed Description

The invention is further described below with reference to the accompanying drawings and the detailed description.

Referring to fig. 2, the stamping production line for the large support sleeve of the automobile chassis shown in the figure comprises a blanking station 10, a first stretching station 20, a second stretching station 20a, a trimming station 30, a first shaping station 40, a second shaping station 40a, a punching station 50, a separating station 60 and a waste cutting station 70, wherein the blanking station 10, the first stretching station 20, the second stretching station 20a, the trimming station 30, the first shaping station 40, the second shaping station 40a, the punching station 50, the separating station 60 and the waste cutting station 70 are respectively provided with a blanking die, a first stretching die, a second stretching die, a first shaping die, a second shaping die, a punching die, a separating die and a waste cutting die.

The strip 80 for preparing the large support sleeve of the automobile chassis continuously passes through the blanking station 10, the first stretching station 20, the second stretching station 20a, the trimming station 30, the first shaping station 40, the second shaping station 40a, the punching station 50, the separating station 60 and the waste cutting station 70 in a non-breaking mode, when the strip 80 for preparing the large support sleeve of the automobile chassis passes through the blanking station 10, the first stretching station 20, the second stretching station 20a, the trimming station 30, the first shaping station 40, the second shaping station 40a, the punching station 50 and the separating station 60, the intermediate parts obtained by the blanking station 10, the first stretching station 20, the second stretching station 20a, the trimming station 30, the first shaping station 40, the second shaping station 40a, the punching station 50, the separating station 60 and the waste cutting station 70 are not separated from the strip 80 for preparing the large support sleeve of the automobile chassis, the strip 80 used to make the large support sleeve for the chassis of the vehicle is not separated until the scrap cutting station 70.
