Background technology

In machine industry, the blanking of metal bar material is first procedure in the machining process, this procedure is among the procedure for preparation of cold extrusion, die forging, metal bracelet pin, rolling bearing roller, bolt, nut, pin, axle class part etc., the general mode of shearing blanking that adopts is carried out blanking in the prior art, above-mentioned baiting method will cause the bar section to present the shape of a hoof, does not satisfy the operation requirement; In order to reach the requirement of operation, need after common shearing blanking, increase by one lathe turning with the operation of smooth section, reduce production efficiency, wasted material, increased production cost; People improve prior art, adopted low stress shearing blanking technology, circumference on the metal bar material surface utilizes groover to process a sharp-pointed ring-type V-type groove in advance, makes material produce localized cracks at the V-type trench bottom after the loading, relies on the slow expansion of crackle to finish blanking; Present groover is that the above lathe tool of tens of handles is slotted to one section bar simultaneously, and the bar diameter mostly is tens millimeters, when it is slotted, can be subjected to the effect of multiple power, thereby distortion such as bend, and then position and the shape of the ring-type V-type groove that causes out are accurate inadequately, cause the error of ring-type V-type groove.

Summary of the invention

In order to address the above problem, the utility model proposes a kind of simple in structure, to the bar continuous traction and guarantee the fluting accuracy new and effective groover draw material mechanism.

In order to achieve the above object, the technical solution adopted in the utility model is: comprise motor, decelerator, big round nut, last binder sleeve, rolling bearing, binder axle, clamp sleeve, following binder sleeve, press down bolt, press down nut, draw material mechanism upper end cover, compress guide pillar, asbestos board and draw the material mechanism shell; Described motor links to each other with decelerator; Described decelerator links to each other with following binder sleeve; The described binder sleeve of going up is placed in the rolling bearing periphery; Described binder axle left end passes rolling bearing, and right-hand member passes clamp sleeve; The left end of described rolling bearing is spacing by big round nut, and right-hand member is spacing by the binder axle; Described binder axle with compress the guide pillar end face and closely be connected; Described asbestos board places the lower end that compresses guide pillar; Described guide pillar and the asbestos board of compressing all is installed in and draws material mechanism shell inside; Described drawing expected mechanism's upper end cover and drawn the material mechanism shell to be connected by fixed screw; Described press down bolt and press down nut be fixed in and draw material mechanism upper end cover.

As preferably, described decelerator is model C WO80 decelerator.

As preferably, described big round nut and press down the nut below locked spacer is installed.

Further, described motor transmission shaft links to each other by key with decelerator.

Further, the output shaft of described decelerator connects binder sleeve down by key.

Beneficial effect

Mechanism is expected in drawing of new and effective groover of the present utility model, and mechanical mechanism is simple, and environment for use requires low; Continue to rotate the tractive force effect that generation continues to bar by last binder sleeve and following binder sleeve, offset lathe tool to the Cutting Force that bar produces, prevent that bar from occuring bending and deformation in the axial direction, guaranteed the fluting precision.

Description of drawings

In order to be easy to explanation, the utility model is done to describe in detail by following specific embodiment and accompanying drawing.

Fig. 1 is front view of the present utility model;

Fig. 2 is that the A of Fig. 1 is to profile.

Binder sleeve, 8-reducer output shaft, 9-draw material mechanism upper end cover, 10-to compress guide pillar, 11-asbestos board, 12-to draw material mechanism shell, 13-to press down nut, 14-fixed screw, 15-to press down bolt under 1-decelerator, the big round nut of 2-, the last binder sleeve of 3-, 4-rolling bearing, 5-binder axle, 6-clamp sleeve, the 7-.

The specific embodiment

As depicted in figs. 1 and 2, the utility model comprises

Comprise motor (not shown), decelerator 1, big round nut 2, go up binder sleeve 3, rolling bearing 4, binder axle 5, clamp sleeve 6, down binder sleeve 7, press down bolt 15, press down nut 13, draw material mechanism upper end cover 9, compress guide pillar 10, asbestos board 11 and draw material mechanism shell 12; Described motor (not shown) links to each other with decelerator 1; Described decelerator 1 links to each other with following binder sleeve 7; The described binder sleeve 3 of going up is placed in rolling bearing 4 peripheries; Described binder axle 5 left ends pass rolling bearing 4, and right-hand member passes clamp sleeve 6; The left end of described rolling bearing 4 is spacing by big round nut 2, and right-hand member is spacing by binder axle 5; Described binder axle 5 with compress guide pillar 10 end faces and closely be connected; Described asbestos board 11 places the lower end that compresses guide pillar 10; Described guide pillar 10 and the asbestos board 11 of compressing all is installed in and draws material mechanism shell 12 inside; Described drawing expected mechanism's upper end cover 9 and drawn material mechanism shell 12 to be connected by fixed screw 14; Described press down bolt 15 and press down nut 13 be fixed in and draw material mechanism upper end cover 9.
