In described clamp, be provided with back-moving spring, the other end of described back-moving spring is connected in clamp body.
The front surface of described clamp body is provided with front shroud, and the below of described front shroud is provided with the graduated scale for scale patrix position.
The rear surface of described clamp body is provided with back shroud, and described back shroud comprises rear main cover plate, rear left end casing and rear right end casing.
Described hydraulic plumbing system comprises and is placed in the pressure hose of rear main cover plate and is placed in the fuel tap on rear left end casing, the oil pipe being provided with in the port of pressure hose for sealing fixing pressure hose compresses voussoir, and described oil pipe compresses voussoir inside and is provided with the through hole for being communicated with fuel tap and pressure hose.
Described rear right end casing is provided with air bleeding valve.
On described clamp body and bender joint face, be provided with the deflection compensation voussoir for bending upper die deflection compensation.
The present invention is in the time that work is used, by being placed in the bullet ejector pin precompressed bending upper die pocket for the punch head of clamp, prevent that patrix from falling cutter, again by external hydraulic pump to pressure hose oiling, pressure hose moment pressurising distending, withstand voltage oil pipe extruding clamp, clamp moment clamps bending upper die, has realized fast automatic clamping bending upper die.Otherwise, external hydraulic pump pressure release, the back-moving spring that is placed in clamp ejects clamp, clamp extruding pressure hose, in withstand voltage oil pipe, hydraulic oil is extruded, and pressure hose recovers flat form, and clamp and bending upper die unclamp, and have realized quick-detachment bending upper die.Upper die of bending machine clamping device Stability Analysis of Structures of the present invention, use efficient and convenient, clamping force is even, has met that upper die of bending machine quick-detachment is changed, the demand of slider of bender deflection compensation, has improved operating efficiency and the bending product quality of bender.
