Description

Small-size block terminal casing bending device Technical Field The utility model relates to the technical field of bending of distribution box shells, in particular to a small distribution box shell bending device. Background The distribution box is one of the common electrical equipment, has the advantages of small volume, simple installation and no limitation of places, and is more commonly applied. The block terminal needs to use panel in production, and panel need buckle the processing before can assemble the block terminal. Among the current common block terminal casing bending device, generally adopt the cylinder punching press to bend, when bending, fix the block terminal casing earlier, then start the cylinder and make its bending to block terminal casing punching press, but this kind of bending mode causes the damage to block terminal board casing very easily, because the cylinder punching press is at block terminal casing bending process, the stamping workpiece slowly reduces with the contact surface of block terminal casing to be the direct stamping mode, the punching press atress is inhomogeneous, and causes case casing surface abrasion, damage very easily. At present, the prior patent publication No. CN220239704U proposes a distribution box board bending device, which comprises an operation table and a bending table, wherein the top of the operation table is fixedly connected with the bending table, the top of the operation table is fixedly connected with a support, the end part of the support is fixedly connected with a first hydraulic mechanism, the first hydraulic mechanism is vertically arranged, the output end of the first hydraulic mechanism is fixedly connected with a pressing plate, the side part of the operation table is fixedly connected with a portal frame, the top surface of the inner side of the portal frame is fixedly connected with a second hydraulic mechanism, the output end of the second hydraulic mechanism is fixedly connected with a pressing piece, the bottom of the pressing piece is movably connected with a rotating block, the rotating block is provided with a right-angle notch, the bottom of the pressing piece is fixedly connected with a spring, the bottom of the spring is fixedly connected with a floating plate, and the end part of the floating plate is abutted against the inner side surface of the right-angle notch. According to the technical scheme, the double-pressure mechanism is adopted, namely, the floating plate and the pressing plate are used for double-pressure on the distribution box plate, the distribution box plate is stably pressed, the rotatable rotating block structure is utilized for specifically bending the edge of the distribution box plate, the maximum bending angle is ninety degrees, stable bending of the distribution box plate can be realized, the stress is even, the bending effect is guaranteed, the non-direct impact bending is realized, the effects of slow pressure and slow bending are achieved, and the box plate workpiece is not easy to damage. However, the prior art scheme has the following defects in operation: In the prior art, the rotatable rotating block structure is utilized to bend the edge of the distribution box board, but the edge of the right-angle notch formed in the rotating block is quite sharp, two edges of the right-angle notch of the rotating block are respectively propped against the floating board and the distribution box board, one edge of the right-angle notch of the rotating block is extruded by upward moving of the floating board, the rotating block is driven to rotate, the other edge of the right-angle notch of the rotating block is rotated to extrude the distribution box board, the floating board and the distribution box board can be scratched and rubbed by the sharp edge of the two edges of the right-angle notch in the rotating process of the rotating block, scratch damage is generated to the floating board and the distribution box board, and simultaneously, the harshness is also generated in the processing process, the processing precision is reduced, and the working environment is influenced. Disclosure of utility model The utility model aims to provide a small-sized distribution box shell bending device which is mainly used for solving the problems that a sharp edge exists in a right angle notch formed in a rotating block in the prior art, the bending device can be in direct contact with a floating plate and a distribution box plate in the bending process, when the floating plate moves upwards, one side edge of the right angle notch can be extruded so as to drive the rotating block to rotate, meanwhile, the other side edge of the notch can be extruded to extrude the edge of the distribution box plate to complete bending action, and as the edge of the right angle notch is too sharp, obvious scratch and scratch can be generated on the surfaces of the floating plate and the distribution box plate in the rotating process, t
