Abstract

The invention relates to the improved technology of sheet-metal working equipment, in particular to a rear stop and no-go gauge device of a bending machine. The stop and no-go gauge device comprises a stop block arranged on a lifting base and is characterized in that a front penetrating hole and a rear penetrating hole are formed on the lifting base; a driving screw rod matching with a screw is fixedly installed in the front penetrating hole and a vertical guide column is penetrated in the rear penetrating hole; a top plate and a base are fixedly installed at the upper and lower ends of the guide column; an axial hole coaxial to the front penetrating hole on the lifting base is formed on the top plate; the axial hole is used for supporting the polished part at the upper end of the driving screw rod; a retainer ring and a rotating hand wheel are arranged at the upper end of the driving screw rod and the external part extended out of the top plate. The rear stop and no-go gauge device solves problems such as inconvenient operation, worse regulation precision and high processing precision in the rear stop and no-go gauge device of the present bending machine; and a new rear stop and no-go gauge device of the bending machine is provided.

Description

technical field

[0001] The invention relates to the improvement technology of sheet metal processing equipment, in particular to a rear stop gauge device of a bending machine. Background technique

[0002] The stop gauge device in the back gauge mechanism of ordinary hydraulic bending machine is a necessary part for positioning the sheet and ensuring the contour accuracy of the workpiece. Generally, the stop block in the stop gauge device needs to be able to move up and down to a suitable height position according to the shape and size of the bending workpiece. At present, there are two types of rear stop gauge devices in ordinary hydraulic bending: L-shaped plate type stop gauge (see figure 1 ) and three-bar stop gauge (see figure 2 , 3 ). Although the production cost of the L-shaped plate stop gauge is low, the parts are few, and the structure is simple, its disadvantages are also very obvious: first, because the movable material stop plate and the lifting plate conne...
