AI Technical Summary

Technical Problem

Existing sheet metal bending hydraulic presses cannot change the bending shape in real time according to demand, resulting in frequent mold changes, low production efficiency, increased costs, and difficulty in meeting the customized needs of multiple varieties.

Method used

A sheet metal bending hydraulic press was designed. A moving seat and a drive assembly are used to move the stamping block on a hydraulic platform. The stamping block has multiple stamping grooves of different shapes. Combined with a face-changing assembly and a hydraulic assembly, the stamping block can be quickly changed and accurately bent, avoiding the need to change the entire mold.

Benefits of technology

It improves production efficiency, reduces costs, enhances operational flexibility and convenience, and ensures the stability and precision of the bending process.

Abstract

This utility model discloses a sheet metal bending hydraulic press, mainly composed of a hydraulic device body, a movable seat, a stamping block, a face-changing component, and a hydraulic assembly. The hydraulic device body is equipped with a hydraulic platform, and the movable seat is slidably connected to the hydraulic platform, achieving displacement through a drive component. The movable seat is equipped with a stamping block, which has four stamping surfaces of different shapes, each with a unique stamping groove to adapt to different sheet metal bending requirements. The face-changing component can drive the stamping block to rotate and select a suitable stamping surface. The hydraulic assembly is located above the stamping block and is equipped with a hydraulic cutter. Driven by the hydraulic system, the hydraulic cutter can precisely cooperate with the stamping groove to perform precise bending operations on the sheet metal. This device can easily adapt to different sheet metal bending requirements without changing the entire mold, and can easily complete the bending processing of various shapes of sheet metal, greatly improving production efficiency and quality.
