Description

A new abrasive belt grinding machine for steel pipe surface

technical field

The utility model relates to a steel pipe processing equipment, in particular to an abrasive belt grinding machine for the steel pipe surface.

Background technique

In recent years, in the process of product structure adjustment in the steel pipe industry, higher requirements have been put forward for the quality of large-diameter steel pipe products, and in product competition, the proportion of product surface quality is increasing, especially in some key projects Or where the requirements for fluid transportation are high, the quality of the outer surface of the steel pipe directly affects the competitiveness of the product. Generally, the outer surface of the steel pipe produced by the steel pipe factory often has defects such as scars, wrinkles, and thread lines. Surface grinding, there will still be pitting, scratches, local scars and other defects on the outer surface that cannot be completely removed, and the grinding efficiency of the grinding wheel is not high. Therefore, it is difficult to improve the quality of the outer surface of the steel pipe through grinding wheel grinding.

Contents of the invention

In view of the above problems, the utility model designs a new abrasive belt grinding machine for steel pipe surface, which can form a smooth and excessive curved surface with the pipe body contour when grinding the steel pipe surface.

The utility model mainly includes a handle, a frame, a driven wheel, an abrasive belt, a driving wheel, a motor, a positioning bolt, a tension spring, a pin shaft, and a connecting plate. The driving wheel and the driven wheel are installed on the frame through the pin shaft. The belt evenly acts on the driving wheel and the driven wheel, the connecting plate is connected with the frame through the pin shaft, the tension spring is fixed on the pin shaft, two positioning bolts are clamped at both ends, and the handle is fastened to the frame through the positioning bolts After the motor is powered on, it drives the driving wheel to rotate, driving the abrasive belt to move at a certain speed, and supports the whole device through the handle installed above the frame, and adjusts the tension spring between the connecting frame and the connecting plate to realize the abrasive belt and the steel pipe. The tension between them ensures that the abrasive belt can effectively grind the surface of the steel pipe.

The device of the utility model includes the following technical scheme: when the abrasive belt grinds the surface of the steel pipe, it can form a smooth and excessive curved surface with the contour of the pipe body. Since the abrasive belt grinding is a flexible contact, it can ensure that the residual stress on the steel pipe surface is small and the surface is rough. The degree is uniform and small; the driving wheel and the driven wheel are designed in the shape of "I", and the abrasive belt can be manually positioned on the driving wheel and the driven wheel according to the width and position of the abrasive belt to ensure that the abrasive belt does not deviate from the movement track; To make the abrasive belt interact better with steel pipes of different diameters, the tension between the abrasive belt and the steel pipe can be realized by adjusting the tension spring between the connecting frame and the connecting plate, which can not only ensure the surface roughness of the processed steel pipe, but also Can improve the cutting ability of the abrasive belt.

Advantages and positive effects brought by the utility model compared with existing devices:

1. The processing efficiency of the device is much higher than that of the existing grinding wheel grinding, and the heat dissipation in the grinding process is low, and because the abrasive belt is flexible and the grinding speed is stable, the anti-vibration performance of the device is very good.

2. The surface roughness of the steel pipe processed by this device is low, the precision is good, and the replacement of the abrasive belt is simple, which can reduce the processing time and save the cost.

3. The device has a simple structure, is easy to operate, and has strong practicability.
