A single wire multi-station wire cutting machine tool

Abstract

A monofilament multi-station wire cutting processing machine tool is used for block machining of annular workpieces and belongs to the technical field of machinery manufacturing. Workpieces, particularly the annular workpieces are simultaneously machined from inside to outside by adopting a filament on different positions of the machine tool, two or more than two movable filament rack assemblies (1) are arranged on a workbench and can radially move along the workbench, each filament rack has a short upper arm and a long lower arm, the filament passes by guide wheels at the ends of the upper arm and the lower arm in an internal common tangent manner, each movable filament rack is fixed on a bottom plate (11) which can rotate around the center of the workbench so as to achieve unequal cutting, guide wheel assemblies (3) and (4) are further arranged on the workbench to guide the filament to transit to an adjacent filament rack and a winding roller, and a workpiece support assembly (2) is further arranged. The machine tool aims to improve machining efficiency and reduce deformation.

Description

technical field [0001] The invention relates to a new type of wire cutting machine tool, which is mainly used for cutting ring parts from inside to outside. It can be used for cutting ring parts in blocks, or for slotting on the inner surface of ring parts. It belongs to the technology in the field of mechanical manufacturing. and equipment. Background technique [0002] Many circular mechanical parts need to be cut from the inside to the outside. For example, according to different models and specifications, tire molds need to be cut into 4, 8, 16 parts, etc. If the existing wire cutting machine is used to cut one by one in sequence, the processing cycle Long, uneven distribution of internal stress, large deformation of parts. To solve this problem, the inventor once proposed a multi-groove synchronous wire cutting machine tool solution, patent number 200810026060.5, which can realize multi-station synchronous processing. However, the disadvantage is that in order to ensu...

AI Technical Summary

Problems solved by technology

However, the disadvantage is that in order to ensure that the length of the wire outside the winding drum does not change due to the change of the position of the wire frame, a wire storage mechanism with many guide wheels is designed, which makes the wire path of the machine tool tortuous and the structure of the machine tool is complicated. , frequent turning also reduces the life of the silk thread

In addition, ring parts can only be cut in equal parts or fixed-position block cutting, but position-adjustable unequal cutting cannot be realized
