Abstract
The utility model relates to an assembled radial automatic feeding cutting-off tool, which can be arranged on a common lathe or a numerically controlled lathe for use. The assembled radial automatic feeding cutting-off tool is characterized in that the R30mm cambered surface of the front end of the tool body is connected with a 90-degree step of the rear part, the G surface thereof is attached to the bottom side of a tool rest and bears the main cutting force in cutting; the two ends of a tool bar are welded with cemented carbide blades, the front tool faces are 14-degree rake angle of R75mm radius cambered surface of a grinding wheel, the main rear faces are manufactured into convex cutting edges so as to lead the cutting force to move backwards; the toolbar is inserted into an installation through slot of the left outer side of the tool body; screws P1 and P2 at the left side of the tool rest are used for simultaneously compressing and fixing the tool bar and the tool body on the left side slot of the tool rest; and the tool has no radial and axial displacement in cutting. The assembled radial automatic feeding cutting-off tool has simple structure and strong overall rigidity, with the production efficiency of being 4-6 times that of the conventional used cemented carbide cutting-off tool.
Description
Technical field
The utility model relates to radially auto-feed parting-off tool of a kind of assembled, and particularly a kind of assembled that can use on common or numerically controlled lathe is the auto-feed parting-off tool radially.
Background technology
At present, on common or the numerically controlled lathe in to the cut-out of all kinds of rod iron material processing, use mostly be carbide alloy welded type or disposable type parting-off tool.The cutting of this two classes cutter partly approaches owing to long, cause the inadequate natural endowment of its rigidity, the geometry design of blade cut sword is unreasonable in addition, cause the operator all to adopt free-hand jog to come cutting-off part, dare not select the auto-feed process of chopping faster, thereby restricted the raising of production efficiency, make lathe in cutting off processing, be in hysteretic state all the time.
Summary of the invention
Goal of the invention of the present utility model overcomes above-mentioned defective and deficiency exactly, provides a kind of rigidity simple in structure strong, and cost of manufacture is low, and easy to operate and assembled that working (machining) efficiency is high is the auto-feed parting-off tool radially.
The technical solution of the utility model is as follows: a kind of assembled that can use on common or numerically controlled lathe is the auto-feed parting-off tool radially, comprise the groove that an installation knife bar is arranged in the cutter hub front end left-external side, there are 90 ° of steps at R30mm cambered surface and rear portion to link on its right side, there is a through hole on the right side, groove front end top that knife bar is installed, and has two wide groove and perforations of this hole that are 90 ° mutually of 5mm to make it form springhole.
90 ° of steps at described cutter hub front end right side R30mm cambered surface and its rear portion link, and main cutting force is being carried on the base that its step G face is close under the knife rest left side.
Described cutter hub and knife bar are to utilize knife rest left side screw P1, P2 to be fixed.
Described knife bar two ends are welded with carbide chip, and its rake face is 14 ° of anterior angles of grinding wheel radius cambered surface R75mm, and major flank is made the convex cutting edge, makes cutting force move towards the knife bar rear portion.
The utility model links by 90 ° of steps at cutter hub front end R30mm cambered surface and its rear portion, its G face is adjacent on the knife rest base, the knife bar that will be welded with 2 carbide chips again inserts in the installation groove of cutter hub left-external side, utilize knife rest left side screw P, P1 that knife bar and cutter hub are pressed abd fixed in the groove of knife rest left side simultaneously, simple structure, easy to loading and unloading and integral rigidity is strong, its working (machining) efficiency is 4～6 times of the conventional carbide alloy parting-off tool that uses at present.
Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structure general assembly drawing of the present utility model; Fig. 2 is the A-A profile of the utility model Fig. 1; Fig. 3 is the vertical view of the utility model Fig. 1; Fig. 4 is the geometry figure of the utility model figure blade cut sword.
The specific embodiment
For the ease of the utility model is further understood, make technological means, creation characteristic that the utility model realizes, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Wherein: 1, knife bar, 2, blade, 3, cutter hub, 4, knife rest.
As shown in Figure 1, the utility model in use, 90 ° of steps at cutter hub front end right side R30mm cambered surface and its rear portion link, its G face is adjacent on the base under the knife rest left side, two wide 5mm be mutually 90 ° groove with
Perforation makes it form springhole; The rear and front end is welded with the knife bar of carbide chip, is installed in the 16 * 4mm groove in the cutter hub left-external side, and two screw P1, the P2 on the knife rest can be pressed abd fixed on the cutter hub connection in the groove in knife rest left side with knife bar.Carbide chip as shown in Figure 4, the geometry of its cutting edge makes into convex, and rake face is grinding wheel radius cambered surface R75mm and is 14 ° of anterior angles that cutting edge can be right after Passivation Treatment
Do the radially auto-feed of 0.5-0.7r/mm with lower steel piece and cut off, smear metal is and moves after big spiral shell volume makes cutting force, and its main cutting force is carried by 90 ° of steps that link at cutter hub R30mm cambered surface and rear portion thereof.Cutter does not have footpath, axially displaced in the cutting, steady and friction, and optimum cuts off processing in batches.The knife bar material is the 16Mn steel plate, is of a size of 16 * 4 * 100mm, and the blade trade mark is homemade YT14, model: C304, draw materials extensively and cost of manufacture cheap.
Claims (4)
1. assembled auto-feed parting-off tool radially, can be installed on the knife rest of common or numerically controlled lathe and use, it is characterized in that: it comprises the groove that an installation knife bar is arranged in the cutter hub front end left-external side, there are 90 ° of steps at R30mm cambered surface and rear portion to link on its right side, there is a through hole on the right side, groove front end top that knife bar is installed, and has two wide groove and perforations of this hole that are 90 ° mutually of 5mm to make it form springhole.
