Description

Technical Field

[0001] The invention relates to the technical field of forming devices, in particular to a one-step bending forming device for a metal dog pile. Background Art

[0002] A dog leash is a metal dog post bent into a one-step molding device specially used to fix outdoor products for dogs. It is usually made of materials such as stainless steel and has the functions of fixing and pulling. This equipment is usually used for outdoor activities, such as walking or training, to help the owner better control and guide the dog. The design of the dog leash takes into account the safety and comfort of the dog, and also makes it easy for the owner to operate and control. The conventional method of dog tying is to proceed in steps, such as Fig. 9 As shown, the raw material is first bent into a Q shape, and then bent at position B. After the Q shape bending, the angle of the dog bolt needs to be flipped 180 degrees, and then bent at B. Generally, two methods are required to independently implement the above process, and the operation is relatively troublesome. Summary of the invention

Due to the use of the support frame, mounting column fixing sleeve, annular panel, swing arm and pushing mechanism, after the material is bent, the swing arm rotates counterclockwise, and the swing arm drives the fixing ring fixed to it to rotate counterclockwise, so that the second gear and the first gear rotate synchronously, the rack moves downward, and the slider drives the workpiece to move downward to press the bent material, and the pressing position enters Fig. 9Position B of the dog bolt is positioned to make its elbow part warp upward, and finally the dog bolt is formed. Furthermore, there is no need to flip the dog bolt, but only to rotate the swing arm in the opposite direction. The whole process is formed through the deflection of the swing arm, which is more convenient and practical.

[0014] 2. A limit rod and a spring are provided in the U-shaped frame, and the limit rod, the spring and the fixed block on the outer wall of the rack are connected.

[0015] 3. The extrusion parts include a positioning block, a positioning panel and a threaded rod. The threaded rod is rotated to adjust the position of the positioning panel so that it presses against the material. The material is held by hand and pressed against the positioning panel to prevent excessive movement of the material and failure in the bending part. The distance of the positioning panel can be adjusted. BRIEF DESCRIPTION OF THE DRAWINGS
