Abstract

A grading cutting device used for oil cylinder inner hole boring comprises an upper knife rest, a lower knife rest, and a boring head. The end portion of the boring head is provided with the upper knife rest and the lower knife rest. The upper knife rest and the lower knife rest are arranged in a front-back step type. The grading cutting device used for oil cylinder inner hole boring has the advantages that the knife rests are in step type arrangement, cutting amount and tool wear of each cutting tool are reduced, product manufacture cutting thickness can be increased, a production task can be accomplished both in quality and quantity, and production efficiency can be improved.

Description

A kind of stepped cut device that pushes away boring for cylinder bore

[technical field] the utility model relates to the plant equipment parts, specifically a kind of stepped cut device that pushes away boring for cylinder bore.

[background technology] oil cylinder be generally 10-15mm, so the smear metal resistance is large to carry out the cutting output of endoporus when pushing away boring larger, causes cutter consumption serious, has greatly increased the cost of processing; And very easily occur in process planting the cutter phenomenon, make workpiece again and again scrap, incured loss through delay the progress of producing, affected the quality of product.

[summary of the invention] the utility model provides a kind of stepped cut device that pushes away boring for cylinder bore for above problem.

This stepped cut device that pushes away boring for cylinder bore comprises that upper tool post, lower slide and boring head form, and it is characterized in that, the end of boring head is provided with upper tool post and lower slide, and upper and lower knife rest is that the front and back ladder-type distributes.

Upper handle of a knife and lower handle of a knife are respectively charged in the dress cutter spacing of upper and lower knife rest, after using pattern to locate, with bolt, it are compressed, can be good at completing the work of machining.

The utility model has the advantages that: knife rest adopts ladder-type to distribute, and can reduce cutting output and the tool wear of every cutter, can also increase product processing thickness of cutting, and that guarantees both quality and quantity completes production task, thereby has improved production efficiency.
