Abstract
The utility model relates to a reamer, comprising a cutting edge. A cutting edge band is arranged at the front end of the cutting edge and the middle-rear part of the cutting edge is designed into a shape of a round cutting edge along the radial direction of a reamer body. The cutting edge part of the reamer is divided into three segments and the three segments are processed into different shapes, thus realizing the burnishing-in processing on the surfaces of materials in the material-cutting process and improving the processing precision as well as efficiency.
Description
Technical field
The utility model relates to a kind of hinge-squeezed cutter.
Background technology
The blade of existing hinge-squeezed cutter all adopts the cutting land, and material is carried out cutting process, but in the processing processing procedure, cut surface is rough, needs to increase procedure of processing and handles, and wastes time and energy.
The utility model content
Technical problem to be solved in the utility model is to propose a kind of hinge-squeezed cutter simple in structure.
Technical scheme provided by the utility model is: a kind of hinge-squeezed cutter, include blade, and the front end of this blade is made as the cutting land, and postmedian upwards is made as round bladed in the footpath of blade.
For strengthening the burnishing-in performance of hinge-squeezed cutter, the rear portion arc length of blade is greater than the length of middle part circular arc.
The utility model has following advantage: knife edge part is divided into three sections, is processed into difformity, be implemented in the cutting material surface to material and carried out the burnishing-in processing, improved machining accuracy and efficient.
Description of drawings
Below in conjunction with the description of drawings specific embodiment of the present utility model.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is that A-A among Fig. 1 is to view;
Fig. 3 is that B-B among Fig. 1 is to view;
Fig. 4 is that C-C among Fig. 1 is to view.
The specific embodiment
A kind of hinge-squeezed cutter shown in Fig. 1,2,3 and 4 includes blade 1, and its front end is that ream section 11 is made as the cutting land, and the middle part of this blade 1 is excessive burnishing-in section 12, and its rear portion is that accurate burnishing-in section 13 upwards is made as round bladed in the footpath of blade; Wherein, accurate burnishing-in section 13 arc length of blade 1 are greater than the length of excessive burnishing-in section 12 circular arcs.
Process three active sections (referring to vertically) on the blade 1 of each cutter tooth of hard alloy cutter, that is: front end is that ream section 11 (as shown in Figure 2), middle part are that excessive burnishing-in section 12 (as shown in Figure 3), rear portion are accurate burnishing-in section 13 (as shown in Figure 4).1., ream section 11--is anterior longitudinally carbide chip three sections have following effect respectively:, the general structural similarity with ordinary rigid alloy reamer has the cutting land, and main effect is the most of material in the excision allowance.2., excessively burnishing-in section 12--is at carbide chip middle part longitudinally, at the circumferencial direction of alloy blade round sword arranged, and main effect is that the material behind the leading portion ream is carried out the burnishing-in first time.Though do not excise material, can change processing dimension, for the further burnishing-in of accurate burnishing-in section is prepared.3., accurate burnishing-in section 13--is at the rear portion longitudinally of carbide chip, at the circumferencial direction of alloy blade round sword arranged equally, for withdrawing this burnishing-in section back taper slightly smoothly.Main effect is the excessive burnishing-in section in middle part to be processed material carry out accurate burnishing-in, guarantees final processing dimension and surface quality.
Claims (2)
1, a kind of hinge-squeezed cutter includes blade, it is characterized in that: the front end of this blade is made as the cutting land, and postmedian upwards is made as round bladed in the footpath of blade.
2, hinge-squeezed cutter according to claim 1 is characterized in that: the rear portion arc length of blade is greater than the length of middle part circular arc.
