[0031] When gas rod 20 is passed into compressed gas, piston rod extends, and pushes installation assembly to slide on linear optical axis 3 through sliding block 5, and then drives upper bending assembly inside installation assembly to move.

[0032] At the center of the top of operation platform 1, be provided with lower bending block 21, it is the key part of hook raw material bending forming, when installation assembly slides under the driving of gas rod 20, upper bending assembly inside installation assembly moves, and upper bending assembly cooperates with lower bending block 21, and jointly completes the bending operation of hook raw material, and its principle lies in that, upper bending assembly contacts hook raw material placed on lower bending block 21 in the moving process, and exerts pressure, makes raw material to be plastically deformed under the action of upper and lower bending blocks 21, to be bent into the required shape, and lower bending block 21 plays the role of supporting and positioning raw material, and upper bending assembly provides the pressure required for bending, and the both work cooperatively, ensure the accuracy and stability of bending operation.

[0033] Installation assembly drives upper bending assembly to move to above lower bending block 21, and upper bending assembly exerts pressure on hook raw material placed on lower bending block 21, and makes raw material to be bent into shape under the joint action of upper and lower bending blocks 21.

[0034] The installation assembly is mainly composed of the installation frame 4, which is the main structure of the whole assembly and serves as a carrier and a connector of other components. The installation frame 4 is provided with a plurality of sliding blocks 5 on both sides, which are closely fitted with the linear optical axis 3 like the wheels of a train, so that the installation frame 4 can smoothly slide on the linear optical axis 3. Limiting sliding grooves 6 are formed in the inner side walls of the installation frame 4. The limiting sliding grooves 6 serve to position and guide the upper bending assembly.

The upper bending assembly enters the installation frame 4 under the guidance of the limiting sliding grooves 6, and at the same time, it prepares for the cooperation of the self-locking assembly and the fixed limiting seat 18.

[0036] The core component of the upper bending assembly is the upper bending block 16, which directly contacts and bends the hook raw material. The limiting sliding plates 17 are arranged on both side walls of the upper bending block 16 at the top. The limiting sliding plates 17 are matched with the limiting sliding grooves 6 on the inner side walls of the installation frame 4.

[0040] The fixed plate 12 and the mis-touch prevention protective shell 15 are fixedly connected with the mounting frame 4, which ensures the stability of the self-locking assembly on the mounting frame 4, when the roller 10 contacts the inclined surface 19 of the fixed limiting seat 18, the roller 10 will retract and squeeze the compression spring 13 due to the force of the inclined surface 19, at this time, the compression spring 13 converts the external mechanical force into elastic potential energy and stores it, when the roller 10 is separated from the fixed limiting seat 18, the compression spring 13 releases the previously stored elastic potential energy to drive the limiting block 9 and the roller 10 to return to the original position under the action of the connecting rod 11, the limiting block 9 after returning to the original position is just located between the two fixed limiting seats 18, the limiting block 9 is limited by the two fixed limiting seats 18, thereby realizing the fixed limiting of the upper bending block 16, this self-locking mechanism ensures that the upper bending block 16 can work stably during the bending of the hook and will not be displaced due to external force, which ensures the accuracy and consistency of the bending operation and greatly improves the product quality, when the upper bending block 16 needs to be disassembled, the operator only needs to pull the pulling block 14, the pulling block 14 drives the limiting block 9 and the roller 10 to retract, so that the limiting and fixing of the upper bending block 16 can be easily released, compared with the traditional fixing method, the disassembly process is greatly simplified.

[0041] When the upper bending block 16 is installed, the roller 10 acts with the slope 19, compresses the spring 13; returns to the original position and is locked; when it is disassembled, the pulling block 14 is pulled to unlock.
