Roll spacing adjustment device for cold roll forming machine

Abstract

A cold bend forming machine roller interval adjustment device comprises a machine body, a roller unit, an interval adjustment unit, a linkage adjustment unit and a drive unit; the interval adjustment unit comprises an upper ram, a lower ram and return springs, and the top of the upper ram is fixedly provided with ejector rods passing through a beam; the linkage adjustment unit comprises multiple inclined iron sliding blocks, a push-pull rod and a push-pull rod adjustment mechanism, the inclined iron sliding blocks are arranged by corresponding to positions of the ejector rods, the multiple inclined iron sliding blocks are all mounted on the beam in a way of being capable of sliding longitudinally relative to the beam, the bottom of each inclined iron sliding block is provided with an ejector rod chute, the bottoms of the ejector rod chutes are longitudinal slopes, the ejector rods are in pressure contact with the longitudinal slopes under the acting forces of the return springs, and the push-pull rod is arranged above the beam and is connected the inclined iron sliding blocks in series. The cold bend forming machine roller interval adjustment device is high in adjustment efficiency, good in unification and harmonization, free of manually and repeatedly debugging by using a filler gauge, high in automation degree and capable of being combined with an electrical control system.

Description

technical field [0001] The invention relates to a cold-bending forming machine, in particular to a device for adjusting the distance between rolls of the cold-bending forming machine. Background technique [0002] The cold roll forming machine is a machine that continuously bends metal plates such as coils and strips transversely through sequentially configured multi-pass forming rolls to make plastic processing machines of specific cross-section profiles. The roll is the core component of the cold roll forming machine, and the distance between the upper and lower rolls needs to be adjusted according to the thickness of the material and the processing technology requirements; Assemblies and sliding columns, the upper roller assembly and the lower roller assembly are installed and fixed on the sliding column, and the sliding column is arranged between the beam and the base of the machine body; the upper roller assembly includes the upper roller, the upper roller shaft and the...

Problems solved by technology

The roll is the core component of the cold roll forming machine, and the distance between the upper and lower rolls needs to be adjusted according to the thickness of the material and the processing technology requirements; Assemblies and sliding columns, the upper roller assembly and the lower roller assembly are installed and fixed on the sliding column, and the sliding column is arranged between the beam and the base of the machine body; the upper roller assembly includes the upper roller, the upper roller shaft and the upper ram, and the upper roller is fixed On the upper roller shaft, the upper roller shaft is installed on the upper ram through the bearing, and the upper ram is installed on the ram; the lower roller assembly includes the lower roller, the lower roller shaft and the lower pillow, and the lower roller is fixed on the lower roller shaft. The roll shaft is installed on the lower pillow through the bearing, and the lower pillow is installed on the sliding column. Therefore, by adjusting the relative spacing between the upper and lower pillows installed on the sliding column, the distance between the rolls can be adjusted. The rolls of the cold roll forming machine in the prior art The distance adjustment device usually fixes the lower ram on the sliding column, adjusts the height of the upper ram installed on the sliding column, and fixes it with screws after adjustment. However, the adjustment accuracy of this adjustment method is difficult to guarantee, and it needs to be adjusted manually through the feeler gauge , the efficiency is low. In the prior art, in order to achieve better adjustment accuracy, as described in the patent No. CN200820163031.9, a screw is set on the upper ram, the screw passes through the beam, and a corresponding Matching adjusting nuts, through adjusting the nuts to adjust the distance between the rolls, although the efficiency of this method has been improved, but the cold roll forming machine is equipped with multiple passes of forming rolls in sequence, when using this device to adjust the distance between the rolls, it is necessary to adjust the distance between the rolls The spacing adjustment units are adjusted one by one, and every adjustment of a spacing adjustment unit requires repeated measurement and adjustment with a plug gauge. Usually, the measurement space of the spacing adjustment unit is relatively narrow, inconvenient to operate, and the measurement error is relatively large, requiring high technical experience for workers. The adjustment process takes a long time. Every time you replace products with different thicknesses, you need to repeat the adjustment one by one. It cannot be adjusted uniformly, and there is no automation at all. The efficiency is still low, and the device is difficult to integrate with the electrical control system.

Therefore, the roll spacing adjustment device of the cold roll forming machine in the prior art has the problems of low adjustment efficiency, poor coordination, strong manual dependence, and difficulty in integrating with the electrical control system.
