Automatic cutting and grinding integrated device for galvanized pipes

Abstract

The invention relates to an automatic cutting and grinding integrated device for galvanized pipes. The automatic cutting and grinding integrated device comprises a bottom plate, a supporting and locking mechanism and a notch grinding mechanism, and is characterized in that the supporting and locking mechanism comprises a placing table, a pressing unit, a sliding plate, a supporting frame, an adjusting and locking unit, a limiting baffle and an inner supporting unit; and the notch grinding mechanism comprises a sliding base, a lead screw, a rotating motor, a limiting disc, a grinding table, a supporting spring and a grinding unit. The problems that in the prior art, when automatic cutting treatment is conducted on galvanized pipes, a worker holds a grinding machine to grind notches mostly, batched grinding cannot be conducted on the notches, the grinding efficiency is low, end opening grinding is uneven, the smooth degree of the surfaces of the notches is affected, the notches cannot be fixed before being ground, the stability of the galvanized pipe is poor during grinding, the notch grinding precision is affected, the galvanized pipe cannot be stably supported from the inside, and the notch is prone to deformation due to heat generated by grinding are solved.

Description

technical field [0001] The invention relates to the technical field of galvanized pipe fittings, in particular to an integrated automatic cutting and polishing device for galvanized pipe fittings. Background technique [0002] Galvanizing refers to the surface treatment technology of coating a layer of zinc on the surface of metal, alloy or other material pipe fittings to improve the appearance and anti-rust ability of pipe fittings. The main method used is hot-dip galvanizing. The hot-dip galvanized galvanized layer is thick, and has the advantages of uniform coating, strong adhesion, and long service life. Galvanized pipe fittings generally need to be cut after galvanizing to meet normal use requirements. According to the cross-sectional shape formed after cutting, they can be divided into galvanized round pipes and galvanized square pipes. It is a rectangular galvanized square tube. [0003] Regardless of whether it is a galvanized square pipe or a galvanized round pipe...

AI Technical Summary

Problems solved by technology

[0003] Regardless of whether it is a galvanized square pipe or a galvanized round pipe, the cross-section cut will be uneven after cutting, and there will be burrs on the surface of the cut, which may scratch the construction personnel and affect the installation accuracy of the galvanized square pipe. It is very necessary to polish the incision of the square tube after cutting

[0004] The existing galvanized pipe fitting automatic cutting processing device has the following defects: 1. Most of the incisions are polished by manual hand-held grinders, which cannot be polished in batches. Smoothness; 2. The existing automatic cutting processing device for galvanized pipe fittings cannot fix the incision before grinding, resulting in poor stability of galvanized pipe fittings during grinding, which affects the grinding accuracy of the incision, and cannot stably support it from the inside, resulting in grinding. Heat tends to deform the cut
