Multi-straightening head-based quick straightening device and method

Abstract

The invention discloses a multi-straightening head-based quick straightening device and a multi-straightening head-based quick straightening method. Two sides of a conveying roller table are respectively provided with a linear guide rails and a rack parallel to the conveying roller table in turn; two linear guide rails are respectively provided with three slide blocks; one end of each slide block is provided with a step motor which is meshed with the racks through a gear; the other end of each slide block is provided with a straightening head; two ends of the two racks are respectively provided with a limit block; one end of one of the linear guide rails and one side of a conveying channel are provided with three laser sensors which are in the same line at equal intervals and are parallel to the conveying channel; the three laser sensors and the step motors are connected with a computer; the computer determines the movement and feed of each straightening head by analyzing data acquired by the three laser sensors; and the computer makes the slide blocks drive the straightening heads to move in the direction of the linear guide rails by controlling the step motors. The device and the method can realize quick straightening of single-arc and S-shaped workpieces.

Description

technical field [0001] The invention relates to an automatic straightening device and method, in particular to a fast straightening device and method based on multiple straightening heads. Background technique [0002] Many workpieces will be bent and deformed after processing, which will seriously affect the quality of the workpiece, so the workpiece needs to be straightened. At present, hydraulic straightening machines at home and abroad generally adopt a single-point, fixed straightening mode. When straightening, the workpiece is simply supported between two support blocks, and the straightening head in the middle applies a certain reverse straightening load to the workpiece. The workpiece produces reverse bending deformation under the load. If the deformation is partly rebounded after the straightening head is lifted, partly is permanent plastic deformation. If the rebound amount is equal to the reverse bending amount of the workpiece, the workpiece is straightened. The...

AI Technical Summary

Problems solved by technology

The support block and straightening head of this type of straightening device mostly adopt a fixed structure in the horizontal direction, which is difficult to adjust according to the different bending degrees of the workpiece, and there is only one or a pair of straightening heads. This mode can solve single arc Bending form, and there are many forms of bending deformation of the workpiece. In production practice, the deformation of the workpiece is often S-bend. If the traditional fixed, single-arc straightening device cannot straighten the S-bend at one time, the S-bend needs to be straightened. It is decomposed into a single arc for straightening, which requires frequent manual adjustment of the support block, and the straightening efficiency is low, which cannot meet the requirements of production practice.
