The specific embodiment

For further understanding utility model content of the present utility model, characteristics and effect, exemplify following examples now, and the conjunction with figs. detailed description stepping control device that uses of the present utility model is as follows on hydraulic press:

As showing of Fig. 1, the stepping control device that on hydraulic press, uses of the present utility model, include the ratchet structure A of the mechanical driving device action that drives hydraulic press and promote the detent mechanism B that ratchet structure A moves, described ratchet structure A is provided with ratchet 13, described detent mechanism B is provided with ratchet 3, described ratchet 3 is by moving the stroke of setting to ratchet structure A, contacts with ratchet 13 and promotes ratchet 13 and do counterclockwise stepping rotation.

Described ratchet structure A and detent mechanism B are respectively by hold-

down screw

20,12 corresponding being fixedly installed on the hydraulic press 24.

Described ratchet structure A includes: be fixed on the ratchet bracing frame 1 on the hydraulic press 24, the clutch shaft bearing 15 and second bearing 23 on ratchet bracing frame 1 two ends of being fixed on by clutch shaft bearing lid 16 and second bearing cap 2 symmetries respectively, be supported on the axle 14 on the clutch shaft bearing 15 and second bearing 23, described ratchet 13 is arranged on the axle 14 and between two bearings 15,23, can rotate around axle 14.One end of described axle 14 runs through and stretches out clutch shaft bearing 15, and this end of described axle 14 is provided with electromagnetic clutch 19, is fixedly connected with shaft coupling 17 by screw 18 on the described electromagnetic clutch 19.
