A one-time automatic forming machine for hooks with replaceable molds

Abstract

The invention discloses a die-replaceable one-step automatic forming machine for a lifting hook. The forming machine mainly comprises a fixed rack, a rotating rack, a center shaft component, a rotating power mechanism, a clamping mechanism and a rotating die propulsion mechanism, wherein the lower end of the fixed rack is fixed on the ground; a sliding way and threaded holes are arranged on the fixed rack; the rotating power mechanism mainly comprises three hydraulic motors, forged gears, a rotating support and the rotating rack; a sliding way, threaded holes and the die propulsion mechanism are arranged on the rotating rack connected with the rotating support; the die propulsion mechanism mainly comprises a rotating hydraulic cylinder, a rotating die connecting block and a rotating die; the clamping mechanism mainly comprises an active clamping hydraulic cylinder, a passive clamping hydraulic cylinder, clamping connecting blocks and clamping dies; the center shaft component mainly comprises a center shaft, an upper shaft sleeve, a lower shaft sleeve, a bearing, an upper end cover, a lower end cover and a fixed circular platform. The forming machine is high in production efficiency and automation degree, low in labor cost, convenient to operate, die-replaceable and suitable for producing lifting hooks with various specifications in batches.

Description

technical field [0001] The invention relates to an automatic hook forming machine. Background technique [0002] The hook is the most widely used pick-up device on hoisting machinery, and it is also the main load-bearing part of hoisting machinery. The traditional hook manufacturing is to heat the raw material of the hook to a high temperature state, and then carry out multiple processes of pier thickening, elongation, and bending through stamping equipment, and then perform multiple die forging to complete. In the entire processing process, each process often requires multiple stampings to achieve the desired effect. During the stamping process, the hook of the same specification often needs to replace a variety of molds for stamping to ensure the size and accuracy requirements. Control is mainly done manually. Therefore, although the traditional processing technology has been able to process reliable hooks, its production efficiency is low, labor cost is high, workers ar...
