Double-ended bending machine for metal tube

Abstract

The invention provides a double-ended bending machine for a metal tube. The double-ended bending machine comprises a machine base, a stamping bending device, a loading device, an unloading device anda lifting drive device, wherein the stamping bending device comprises an elastic lifting base, a bottom mould, two hinged bases, two bending moulds and a stamping mould; the bottom mould is elastically mounted on the elastic lifting base in a lifting mode; two hinged bases are relatively mounted at the two ends of the elastic lifting base; the bending mould is hinged on the hinged bases; return springs are connected between the bending moulds and the machine base; limiting baffle blocks are formed between the bending moulds and the hinged base; the stamping mould is arranged above the bottom mould through the lifting drive device in a lifting mode; a bottom side groove is formed in the bottom mould; bending grooves are formed in the bending moulds; a top side groove, which corresponds to the bottom side groove, is formed in the bottom surface of the stamping mould, and an inclined groove is formed in the inclined surface of the stamping mould; and the loading device and the unloading are separately used for automatic loading and automatic unloading. The double-ended bending machine for the metal tube is beneficial for safely producing and improving production efficiency.

Description

technical field [0001] The invention relates to metal pipe bending equipment, in particular to a metal pipe double-head bending machine. Background technique [0002] The multi-layer document basket made of metal tube material includes a support frame and a plurality of net baskets installed on the support frame. Two connecting pipes between two double-end bent metal pipes. Double-end bent metal pipes are usually made by bending straight pipes at both ends. The existing bending devices are not sufficiently automated and rely too much on manual labor. Operation to complete the bending, there are safety hazards in the operation process, and the production efficiency is low. Contents of the invention [0003] In view of the above, the present invention provides a metal tube double-head bending machine, which can automatically complete the entire process, reduces the risk of manual operation, and is conducive to safe production and improved production efficiency. [0004] Th...
