Inner and outer chamfering cutter head of end facing machine

Abstract

The invention creatively provides an inner and outer chamfering cutter head of an end facing machine. The inner and outer chamfering cutter head comprises a cutter head body, a base, a chamfering cutter device and an end facing cutter device, wherein the chamfering cutter device is connected with a first angle adjusting device which is fixedly connected with the base; the end facing cutter device is connected with a second angle adjusting device which is fixedly connected with the base; a burr removing device is arranged in the inner center of the base; a fixing plate is connected to one inner side of the base through a bolt, and while an opening is formed in the other inner side of the base; the burr removing device comprises a fixing seat, an electric rod and a rotating burr removing device which are sequentially connected, wherein the fixing seat is fixedly connected with the fixing plate; the rotating burr removing device can move in and out of the opening through the electric rod. The inner and outer chamfering cuter head is safe, reliable, and convenient to dismount, and can reduce the burr.

Description

technical field [0001] The invention relates to the field of spare parts of a flat head machine, in particular to an inner and outer chamfering cutter head of a flat head machine. Background technique [0002] The flat-end machine is the necessary equipment for the production and manufacture of welded pipes. In order to improve the automation degree and production speed of the welded pipe end processing, the research and development of the flat-end machine has become an inevitable trend. At present, most domestic manufacturers process the end faces of welded pipes until the end faces are milled flat with cutters, without internal and external chamfering. There will be problems with only milling flat ends: [0003] (1) In the subsequent process, during the hydraulic test, due to the presence of burrs, the sealing ring is often scratched, causing water pressure to leak, failing to reach the specified pressure, and affecting the pressure test effect. [0004] (2) When the ste...

AI Technical Summary

Problems solved by technology

[0003] (1) In the subsequent process, when doing the hydraulic test, due to the presence of burrs, the sealing ring is often scratched, causing the water pressure to leak, failing to reach the specified pressure, and affecting the pressure test effect

[0004] (2) When the steel pipe is galvanized, due to the burrs on the end surface, the zinc liquid remains in the steel pipe, resulting in an increase in zinc consumption, which affects the quality of galvanizing and the cost of galvanizing

[0005] (3) When welding the wire, due to the existence of burrs on the end surface of the steel pipe, the knife is used when the wire is cut, which affects the quality of the wire and welding

[0006] (4) Due to the existence of burrs, it not only affects the appearance quality of the steel pipe, but also easily scratches the arm during the handling process, causing accidents
