Abstract
The invention belongs to the field of cutting tools for machining large and extra-large collars, and mainly relates to a double-blade cutting tool with a novel structure. The double-blade cutting tool with the novel structure comprises two blades including a blade I (4) and a blade II (5), and the shape and the size of the blade I (4) are completely identical to the shape and the size of the blade II (5); and a tool cutting edge angle of the blade I (4) and a tool cutting edge angle of the blade II (5) are 45 degrees, and the blade I (4) and the blade II (5) are parallelly arranged on the same plane of the cutting tool, are arranged front and back relative to a cutting feed direction and are vertically arranged relative to a turned surface of a workpiece, so that the blade I (4) is arranged in the front of the cutting feed direction while the blade II (5) is arranged at the rear of the cutting feed direction, the blade I (4) is arranged above the turned surface of the workpiece while the blade II (5) is arranged on below the turned surface of the workpiece, and the double-blade cutting tool with the novel structure can be used for turning the workpiece in a gradient manner. The double-blade cutting tool has the advantages that the requirement on the machining precision can be met, the machining efficiency is greatly improved, the double-blade cutting tool can be adjusted conveniently, different cutting effects can be realized by combining different blades with one another, and the service cost is greatly reduced.
Description
Technical field
The invention belongs to the cutter field of machining large, super-huge lasso, relate generally to a kind of double blade cutter of new structure.
Background technology
As shown in Figure 1, being used for machining large, super-huge lasso now mainly processes with the cutter that brazed shank tool or machine press from both sides single blade.Forging surplus large-scale, super-huge lasso very big (monolateral surplus surpasses more than the 6mm) need repeat turning when processing inner surface or outer surface and just can reach process 3 ~ 4 times, and working (machining) efficiency is very low.For there not being cooling water to help the lathe of heat radiation, cutting-in is very restricted when cutting at every turn.If adopt big cutting-in cutting, ordinary blade is not durable very much, adopts the blade of special substance to process, and can significantly improve use cost, and the mode that can only take little cutting-in repeatedly to cut is processed now.
Summary of the invention
For solving the problems of the technologies described above, the objective of the invention is to propose a kind of double blade cutter of new structure, be mainly used in machining large, super-huge lasso, can realize that the cutting of big cutting-in and rough turn, finish turning once finish.
The present invention adopts following technical scheme for finishing above-mentioned purpose:
A kind of double blade cutter of new structure, described double blade cutter have profile, identical two blades of size, i.e. blade I and blade II; The tool cutting edge angle of described blade I and blade II is 45 °, described blade I and blade II are arranged in parallel on the same plane of cutter, described blade I and blade II are with respect to arranging before and after the direction of feed and with respect to the turning surface upper and lower settings of workpiece, thereby constitute the blade I preceding, the blade II after, the blade I is last, and the blade II is carried out the double blade cutter of a kind of new structure of echelon turning down to workpiece.
The material of described blade I, blade II is identical.
Described blade I, blade II adopt different materials to make.
Described blade I, blade II can have different tool arcs.
The tool arc of described blade II is greater than the tool arc of blade I.
The present invention not only satisfies requirement on machining accuracy, and working (machining) efficiency is significantly improved, and easy to adjust, and different blade unit realizes different cutting effects, and use cost significantly reduces.
Description of drawings
Fig. 1 is existing machine tooling bearing ring schematic diagram.
Fig. 2 is schematic diagram of the present invention.
Fig. 3 uses the schematic diagram of state for the present invention.
Among the figure: 1, bearing ring, 2, support reference column, 3, gripper jaw, 4, the blade I, 5, the blade II.
The specific embodiment:
With specific embodiment the present invention is illustrated by reference to the accompanying drawings:
A kind of double blade cutter of new structure, described double blade cutter have profile, identical two blades of size, i.e. blade I 4 and blade II 5; The tool cutting edge angle of described blade I 4 and blade II 5 is 45 °, and described blade I 4 and blade II 5 are with respect to direction of feed one in front and one in back, be arranged in parallel on the same plane of cutter with respect to the turning surface of workpiece one on the other, thereby constitute blade I 4 preceding, blade II 5 after, blade I 4 is last, blade II 5 is carried out the double blade cutter of a kind of new structure of echelon turning down to workpiece.Distance up and down between blade II 5 and the described blade I 4 can be regulated as required; If need carry out the cutting of the big cutting-in of big surplus, can suitably increase distance up and down, thereby reach in the tool feeding process once and finish twice cutting, and big cutting output is shared by two blades respectively, the cutting hardness that each blade bears is that the ordinary rigid alloy blade is just competent, need not to increase cost, use expensive blade.A, finish turning turning rough turn as if carrying out is finished, and can suitably reduce distance up and down, and blade II 5 can be carried out little surplus turning, guarantees dimensional accuracy and the surface roughness of finished surface.
Described blade I 4 can have identical material with blade II 5, add man-hour rough turn, carry out the secondary utilization if can be installed in after 5 wearing and tearing of the blade II of back on the position of front blade I 4, so neither influence cutting effect, can reduce use cost again, kill two birds with one stone.
Described blade I 4 can be selected different materials for use as required with blade II 5, and the blade I 4 of front can select the blade II 5 intensity height than the back, shock-resistant, the stubbed blade of tooth shape to remove the higher oxide layer of forging hardness and most of surplus; The blade II 5 of back can select the blade sharper than blade I 4 hardness height, the tooth shape of front to remove the fraction surplus, and Zheng Ti cutting effect can be realized big cutting-in cutting like this, also can take full advantage of the performance of blade, is conducive to the control of the cost of charp tool.
Described blade I 4 can have different tool arcs with blade II 5, and, a finish turning turning rough turn for realizing is finished, and blade I 4 will be removed most of surplus, can select can reduce cutting resistance like this than the little blade of blade II 5 tool arcs; Blade II 5 will be removed the fraction surplus, can select can improve the roughness of finished surface like this than the big blade of blade I 4 tool arcs.
