Detailed Description

The present invention is further described with reference to the accompanying drawings 1-2: the utility model discloses divide into five parts:

head frame part

The headstock part is welded between headstock end plates, a plurality of upper blades are arranged at the front end of the headstock, the blades are different in width, and the width of the blades can be suitable for bending by selecting an upper cutter according to the width of a piece to be bent. The design of the upper knife is a long blade design, and a deep-opening closed sheet metal part can be processed.

The upper knife is fixed on the headstock plate by an upper knife pressing block through screws, and the two ends of the headstock plate are welded with headstock end plates.

Second, bending part

The angle iron of bending and push down the sword piece and all adopt section bar transformation system, processing is convenient to the size design is different width, and the cooperation is gone up the sword and is used. Install simultaneously on the body of bending, the body of bending is whole welded structure, carries out ageing treatment after the welding, stable in structure, and it is light to bend.

And a front pull rod seat is fixedly arranged on the rear reinforcing plate of the bending body by screws.

Third, support part

The supporting knife fixing groove is welded on the machine body plate, and after a notch for installing the supporting knife is machined, the supporting knife is integrally welded on the left wall plate and the right wall plate after being installed. The left and right wall plates are welded on the supporting legs. The requirement on the supporting knife fixing groove is high in the welding and machining processes, so that a welding and machining tool is designed to guarantee machining accuracy in machining. The supporting knife is designed to be different in width and is matched with the upper knife and the bending knife for use.

And a rear pull rod seat is fixedly arranged below the machine body plate and is connected with a pull rod connecting shaft.

Fourth, bending limiting rod mounting part

The bending limiting rod penetrates through the front pull rod seat and the pull rod connecting shaft respectively, when the bending plate is lifted, the bending limiting rod follows up, and when the required bending angle is reached, the handle is locked through the locking bending limiting rod, and the bending angle is limited. Has good limiting effect during batch production. And (5) auxiliary bending.

Because the positions of the front pull rod seat and the rear pull rod seat can respectively move randomly along the length direction of the rear reinforcing plate and the machine body plate of the bending body, the position of the bending limiting rod can be selected according to the position of the bending plate. Convenient spacing and convenient processing.

Fifth, the rear material blocking part

The rear material blocking part comprises a supporting block, a connecting plate, a guide shaft, a material blocking screw rod, a material blocking cushion and the like.
