Linear cutting equipment

Abstract

The invention provides wire cutting equipment. The wire cutting equipment comprises a rotary workbench, traction assemblies and a saw wire, wherein the traction assemblies are arranged on the two sides of the rotary workbench correspondingly and arranged oppositely, and the two ends of the saw wire are connected with the traction assemblies in a one-to-one mode correspondingly; one end of the saw wire sequentially penetrates through the guiding device and the tensioning device of the corresponding traction assembly and is wound on the winding and unwinding device of the corresponding traction assembly. The guiding devices are vertically and slidably connected to the stand column, the stand column is horizontally and slidably connected to the sliding rail, meanwhile, the rotary workbench is used for driving a workpiece to rotate, the cutting posture of a saw line can be changed under driving of the two guiding devices, and a machining track of a complex curved surface is formed; and moreover, the equipment can be flexibly built, and the cost is relatively low.

Description

technical field [0001] The invention relates to a cutting device, especially a wire cutting device. Background technique [0002] In recent years, with the rapid development of aerospace, medical industry, tool and mold manufacturing, and automobile industry, a large number of parts with complex curved surfaces and shapes that are difficult to process and have demanding performance indicators have emerged. Traditional milling, grinding and other curved surface processing methods have problems such as small contact area between the tool and the workpiece (point contact processing), large machining allowance, serious tool wear, and low processing efficiency. The use of line processing technology can effectively improve processing efficiency and material utilization. [0003] In the Chinese invention patent application with the publication number CN111240271A, the applicant proposed a method of rough machining of curved surfaces based on mechanical cutting of flexible abrasive...

[0003] The applicant proposed a method for rough machining of curved surfaces based on mechanical cutting of flexible abrasive grains in the Chinese invention patent application with publication number CN111240271A, in which two A device for realizing the processing method, one is to realize curved surface cutting and processing by controlling the movement of the workpiece relative to the line through the workbench, and the other is to realize the curved surface cutting and processing by controlling the line to perform space sweeping motion on the surface of the workpiece through the mechanical arm; the former Completely rely on the workbench to control the movement of the workpiece. In some processing positions, the workbench and the line will interfere with each other (for example, when the workbench is turned 90° along the line), it is difficult to apply to the processing of complex curved surface parts; the latter requires With the help of multi-joint robotic arm, the equipment cost is relatively high
