Description

Precision machining forming cutter

Technical Field

The utility model relates to the technical field of forming tools, in particular to a precision machining forming tool.

Background

Machining is an abbreviation for machining, which refers to a machining process that removes material by mechanical precision machining. The machining is mainly divided into two major types, namely manual machining and numerical control machining, wherein the manual machining is a method for machining various materials by manually operating mechanical equipment such as milling machines, lathes, drilling machines, sawing machines and the like by mechanical workers. Numerical control machining (CNC) refers to machining by a mechanic using numerical control equipment including machining centers, turn-milling centers, wire-cut electric discharge machines, screw thread cutting machines, and the like. In machining, a tool is required.

The forming tool is a tool of a certain shape which is manufactured to meet the processing requirement. The forming cutter is used for processing, the forming surface can be cut out only by one cutting stroke, the operation is simple, and the production efficiency is high.

At present, there are some shortages in precision machining shaping cutter in the use, for example, shaping cutter in carrying out shaping cutting process to the work piece, and its smear metal is difficult outwards to fly out, can hinder the precision machining of shaping cutter to the work piece, simultaneously, the smear metal of flying out is not blockked by external structure, and the flying out face is great, influences subsequent clearance, simultaneously, shaping cutter's handle of a knife department, and length is fixed relatively, inconvenient length adjustment is unfavorable for shaping cutter's nimble use. Therefore, a precision machining forming tool is needed, chips generated in the machining process of a workpiece can fly out of a cutting machining place, and the length of a cutter handle of the forming tool can be adjusted so as to be convenient to install and use.

For example, the prior patent publication number CN216226960U provides a high-efficiency precision machining forming cutter, the device effectively solves the problem that the conventional cutter must be completed by complex feeding procedures in the using process of the conventional cutter through the arrangement of the first forming cutter, the second forming cutter and the third forming cutter, and sometimes the number of the cutters needs to be increased, the first forming cutter, the second forming cutter and the third forming cutter can simplify the processing procedures, have simple operation and long service life, the conventional cutter is used for originally processing the product, a plurality of cutters need to be fed for a plurality of times in the cutting process, and now the forming surface can be cut by only 3 cutting strokes of the forming cutter, so that the processing time is shortened compared with the prior art, the production efficiency is greatly improved, and the processing cost of enterprises is effectively reduced.

However, the device is only suitable for solving the problems that the common cutter must be completed by a complex feeding program in the using process of the traditional cutter, and the number of cutters is increased sometimes to complete the cutting, so that chips generated in cutting can not fly out of the cutting processing place rapidly, and the length of a cutter handle of a forming cutter is inconvenient to adjust so as to be convenient to install and use.

The existing precision machining shaping cutter, shaping cutter is in carrying out shaping cutting process to the work piece, and its smear metal is difficult for outwards flying out, can hinder shaping cutter to the precision machining of work piece, and simultaneously, the smear metal of flying out is not blockked by external structure, and the flying out face is great, influences subsequent clearance, and simultaneously, shaping cutter's handle of a knife department, length is fixed relatively, inconvenient length adjustment carries out, is unfavorable for shaping cutter's nimble use.
