AI Technical Summary

Technical Problem

In the process of stamping stainless steel coils, existing multi-station hydraulic forming machines suffer from defects such as surface scratches and indentations due to the lack of pretreatment, resulting in oil stains and other contaminants. This affects the appearance quality and processing accuracy of the products and increases subsequent repair costs.

Method used

Before the roll material is conveyed, the cleaning roller is driven by the electric push rod of the cleaning mechanism to clean the surface of the roll material. Combined with the support and tension adjustment of the auxiliary roller, the roll material is kept taut to achieve continuous stamping operation.

Benefits of technology

It effectively removes dirt from the surface of the roll material, ensuring stamping accuracy and product quality, reducing the cost of subsequent grinding and finishing processes, and improving production efficiency.

Abstract

The utility model discloses a multi-station hydraulic forming machine for a high-grade stainless steel watchcase blank, relates to the technical field of multi-station hydraulic forming machines, and overcomes the defects that if a stainless steel coiled material is not pretreated, attachments such as oil dirt carried on the surface of the stainless steel coiled material can cause obstruction in the stamping process, and the surface of a watchcase is prone to being scratched and indented. According to the technical scheme, the problems that product appearance quality and machining precision are affected, and the process cost of subsequent grinding and finishing is increased are solved, a cleaning mechanism comprises a supporting rack, the cleaning mechanism comprises an electric push rod and a mounting block, and a first cleaning roller and a second cleaning roller which are detachable are fixedly mounted on the surface of one side of the mounting block correspondingly. Before the coiled material is conveyed, the electric push rod is started to push the mounting block to move upwards to a matched position, then the first cleaning roller and the second cleaning roller are attached to the upper surface and the lower surface of the coiled material respectively and correspondingly mounted on one side of the mounting block, and dirt attached to the surface of the coiled material can be removed through double-roller clamping contact.
