Abstract

The utility model provides a radial shearing force elimination mechanism of a cam linear active pressure bar, comprising a cam, a cam profile wheel contacted to the cam, a workpiece and an active pressure bar. The upper end surface of the active pressure bar is provided with a roller; the workpiece is fixedly provided with a fixed axle seat; the roller is provided with a floating arm through a pin; one end of the floating arm is connected with the fixed axle seat, and the other end is connected with an adjustable support fixedly arranged on the cam profile wheel; the floating arm is fixedly connected with the adjustable support through a screw; the floating arm is connected with the fixed axle seat through a fixed axle seat pin; and the cam profile wheel is connected with the adjustable support through a cam profile wheel pin. According to the radial shearing force elimination mechanism of a cam linear active pressure bar, the radial shearing force of the active pressure bar is eliminated, the movement speed of the mechanism is increased by times, the processing period is shortened, and the production efficiency is raised.

Description

A kind of cam is moving initiatively depression bar radial shear power eliminating machine directly

Technical field

The utility model belongs to mechanical field, relates in particular to directly moving initiatively depression bar radial shear power eliminating machine of a kind of cam.

Background technique

In the machinery such as the direct-acting type punching press in the cam mechanism mode as power or compression assembling, all be that the roller of doing relative movement with cam profile directly is installed on the active depression bar, when active depression bar and cam are done relative movement, initiatively depression bar will produce a stress---the radial shear power relative with moving direction, the generation of this power has retrained mechanical motion or rotating speed greatly, the initiatively axial wearing and tearing of depression bar have also been strengthened simultaneously, both reduced working efficiency, the maintenance that has also increased equipment drops into.

Summary of the invention

The utility model provides directly moving initiatively depression bar radial shear power eliminating machine of a kind of cam, has solved the radial shear power relative with moving direction that produces when initiatively depression bar is done relative movement with cam in the background technique to the shortcoming of the impact of machinery and axial wearing and tearing.

The technical solution of the utility model is achieved in that directly moving initiatively depression bar radial shear power eliminating machine of a kind of cam, comprise cam, with the contacted cam profile wheel of cam, workpiece and depression bar initiatively, initiatively roller is established in the depression bar upper-end surface, fixedly be equipped with fixedly axle bed on the workpiece, be provided with unsteady arm by bearing pin on the roller, arm one end that floats links to each other with fixing axle bed, the other end be fixed on the adjustable support that cam profile takes turns and link to each other;

Unsteady arm and adjustable support are screwed;

The arm that floats links to each other with stationary axle seat pin axle with fixing axle bed, and cam profile is taken turns and taken turns bearing pin with adjustable support with cam profile and link to each other.

The beneficial effects of the utility model are: a kind of cam of the present utility model is moving initiatively depression bar radial shear power eliminating machine directly, eliminated the initiatively radial shear power of depression bar, the movement velocity of lifting gear has shortened the process-cycle at double, has improved significantly manufacturing efficiency.

Part explanation: 1, cam, 2, the cam profile wheel, 3, adjustable support, 4, the arm that floats, 5, roller, 6, depression bar initiatively, 7, fixing axle bed, 8, workpiece, 9, stationary axle seat pin axle, 10, bearing pin, 11, cam profile takes turns bearing pin.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described: a kind of cam is moving initiatively depression bar radial shear power eliminating machine directly, comprise fixedly axle bed 7, arm 4 floats, roller 5, adjustable support 3, fixedly axle bed 7 is fixed on the workpiece 8 with respect to camming movement, by stationary axle seat pin axle 9 be installed in roller 5 on the arm 4 that floats and form one take fixing axle bed 7 as the center of circle, rotation motion take the center of active depression bar 6 as radius is secondary, adjustable support 3 forms another kinematic pair by cam profile wheel bearing pin 11 and cam profile wheel 2, adjustable support 3 usefulness screws and unsteady arm 4 are fixed together, at cam with it in workpiece 8 movement processes of relative movement, cam profile wheel 2 moves on the profile that is pulled in cam 1 of the arm 4 that floats, height on cam 1 profile acts on the arm 4 that floats through cam profile wheel 2 apart from variable, be delivered on the end face of active depression bar 6 by the roller 5 on the arm 4 that floats again, make initiatively and obtain pure axial height apart from variable on the depression bar 6.
