Excircle grinding machine for forged bars

Abstract

An excircle grinding machine for forged bars is characterized by comprising two parts. One part is a trolley for placing the processed bars, trolley wheels are arranged on the lower part of the trolley, a trolley walking motor, a main shaft rotating motor and two rows of rotary wheels are arranged on the upper part of the trolley, one row of the rotary wheels are driving wheels driven by the main shaft rotating motor, the other row of the rotary wheels are driven wheels, when the machine is started up, the trolley walking motor drives the trolley to slowly move on a track, the processed bars are axially fed, and the main shaft rotating motor drives the rotary wheels on the trolley to rotate. The other part is a grinding main machine, which comprises components of a grinding head base, a grinding head rotary shaft, a grinding head, a grinding head motor and a balance cylinder, when the machine is started up, the grinding head motor drives the grinding head to rotate, the grinding head can rotate for 120 degrees around the grinding head rotating shaft through a connecting mechanism, the force applied to the processed bars by the grinding head is adjusted by adjusting the height of an ejector rod in the balance cylinder, so that the grinding head and the processed bars are radially fed, and grinding on the surfaces of the bars are realized.

Description

technical field [0001] The invention belongs to the field of forging bar surface processing machinery, in particular to a Ф110-Ф480 cylindrical grinding machine used for processing and cleaning the outer surface of forging bars. Background technique [0002] After the steel ingot is turned into a bar through forging, there will be various degrees of defects such as scars, cracks, skinning, and folding on the surface of the bar. If these defects are not removed, it will greatly affect the processing quality of subsequent processing. , easily lead to waste. Usually to eliminate these defects, it is to grind and clean the grinder by hand. It has four main disadvantages. [0003] First, the labor intensity of workers is high. The weight of the grinding wheel itself is already very heavy, and the grinding force of the grinding wheel depends on a certain amount of pressure given by people. Therefore, the physical strength of the workers is very large, the labor intensity is high...

AI Technical Summary

Problems solved by technology

The weight of the grinding wheel itself is already very heavy, and the grinding force of the grinding wheel depends on a certain amount of pressure given by people. Therefore, the workers have to pay a lot of physical strength, labor intensity is high, and the work is particularly hard.

[0004] Second, the grinding quality is poor

The worker grinds the grinding wheel by hand, and the bar is fixed. The grinding formed in this way is point-shaped, and the local surface shape tolerance is particularly irregular. Local bluing often occurs, which leads to surface cracks and many quality problems.

[0005] Third, the grinding range is small

Since the bars cannot be rotated, the grinding of larger-sized bars is not thorough. Only lighter materials can be used for prying around the surrounding grinding, but the aesthetics are particularly poor. Cutting range is only limited to bars between Φ110—Φ210

[0006] Fourth, low efficiency

Since human strength is limited, the grinding efficiency is particularly low, and it takes a few days to grind a piece of material.
