Guardrail tube deburring machine

Abstract

The invention provides a guardrail tube deburring machine which comprises a machine table. A floating grinding device and a rotating device are arranged above the machine table, and a supporting frame is arranged between the floating grinding device and the rotating device. The floating grinding device comprises a support, a knife rest, a swing rod, a pull rod, a knife rod and a knife holder, wherein the support is arranged on the machine table, the knife rest is arranged above the support, the upper end of the swing rod is fixed on the knife rest through a first bolt, and the lower end of the swing rod is hinged to the middle of the knife rod. A pin shaft is arranged at the upper end of the knife rod, and a through hole is formed in the pin shaft. The upper end of the pull rod is hinged to the upper end of the swing rod, and the lower end of the pull rod penetrates through the through hole. An anti-falling part is arranged at the lower end of the pull rod, and a spring is arranged on the pull rod in a sleeving mode. The lower end of the knife rod is connected with the knife holder, and a knife is arranged on the knife holder. The guardrail tube deburring machine solves the problems that machining is not complete and knife biting and breakage occur due to the fact that the knife does not float, knife consumption is reduced, the knife replacement time is shortened, the machining quality of guardrail tubes is improved, the effective operation rate of equipment is increased, and the service life is prolonged.

Description

Technical field [0001] The invention relates to the technical field of guardrail tube processing, in particular to a guardrail tube deburring machine. Background technique [0002] Steel pipe is a hollow long round steel, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial transportation pipelines and mechanical structural parts. In addition, when the bending and torsion strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. [0003] Steel pipes can be used as guardrail pipes. All processed steel pipes need to be deburred. Traditionally, the deburring of steel pipes mainly relies on shaped cones or tapered sandstones to deburr the inner and outer edges of the steel pipe. This method of deburring is only applicable It is not suitable for the deburring of large quantities of steel pipes. There are also some equipments that use t...
