Steel pipe grinding device for hardware machining

Abstract

The invention discloses a steel pipe grinding device for hardware machining. The steel pipe grinding device comprises a base, wherein supporting frames are arranged on the two sides of one end of thebase, a rotating cross shaft is arranged between the upper ends of the two supporting frames, a first motor is arranged at the upper end of one side of one supporting frame, an output shaft of the first motor penetrates through the supporting frames to be connected with the rotating cross shaft, a first rotating roller is fixedly connected to the rotating cross shaft in a sleeve mode, the two sides of a second motor are symmetrically provided with first screw rods, the second motor drives a first belt wheel to be in transmission connection with a second belt wheel through a belt, first screw rod nuts are arranged on the first screw rods in a matched mode, a movable cross shaft is arranged between the two first screw rod nuts, a second rotating roller is connected to the movable cross shaftin a sleeve mode, a grinding mechanism is arranged at the other end of the base, and the grinding mechanism comprises a fixed support, a third motor, a screw rod, a spiral lifting sleeve, a sliding sleeve, a pressing plate and a fixing frame. The grinding device is relatively high in grinding efficiency, convenient and rapid, capable of reducing the labor cost, capable of being applicable to grinding of long steel pipes and relatively high in practicability.

Description

technical field [0001] The invention relates to the technical field of hardware processing, in particular to a steel pipe grinding device for metal processing. Background technique [0002] Steel pipes can be divided into seamless steel pipes and seamed steel pipes according to the seamed seamless. Seamed steel pipes are divided into spiral steel pipes and straight seam steel pipes according to different welds. The two are widely used in building piling, structure, steel structure, load-bearing and drainage. The materials are mainly carbon steel, stainless steel and alloy steel. Among them, carbon steel materials are the most widely used, and the main production base is Cangzhou, Hebei. According to the customer's requirements, the length of the steel pipe can be fixed to length or loose. Construction seamless steel pipes can be divided into hot-rolled seamless pipes, cold-drawn pipes, precision steel pipes, hot-expanded pipes, cold-spinned pipes and extruded pipes accord...

AI Technical Summary

Problems solved by technology

Existing grinding equipment for steel pipes usually includes a processing table and a grinding wheel. During work, the steel pipe is fixed on the processing table. Through the rotation of the grinding wheel, the outer circumference of the grinding wheel rubs against the surface of the steel pipe to grind and derust the steel pipe. This method is suitable for cylindrical steel pipes, while square steel pipes are generally moved along the direction of the rod wall by manual hand-held grinders, and repeatedly polished. This grinding method is extremely inefficient and requires a lot of labor, which is not conducive to work.
