[0002] Hardware refers to the general term for various products made of metal materials. Most of these hardware products are not final consumer goods, but are important components or tools in the manufacturing process of other products.

[0003] Screws are a commonly used fastener in hardware products. They are tools that use the inclined circular rotation and friction of an object to gradually fasten objects and parts. When processing and producing screws, it is usually necessary to use a cold heading machine to fasten the metal parts to a certain depth so that their heads are slightly recessed into the fixed mold, so that the metal parts are cold-forged into screws.

[0004] At present, cold heading machines usually place metal parts into molds for cold heading, and use different molds to gradually form the metal parts. This will result in the need to use multiple molds to match screws of different shapes when cold heading the metal parts, resulting in frequent mold changes, which increases the workload, and when the mold is replaced, the processing operation needs to be stopped, delaying the work progress. This method is time-consuming and labor-intensive, and is not convenient for continuous forming of screws, so it needs to be improved and optimized. Utility Model Content

[0035] When it is necessary to perform forming operations on the screw 4, the worker first installs the workbench 1 at a suitable position, then aligns the bottom of the screw 4 with the fixed groove 10 inside the fixed bin 9, and presses downward. At this time, the downward movement of the screw 4 will squeeze the stop block 13, and the squeezing of the stop block 13 drives the movable plate 12 to move toward the inside of the movable groove 11. At this time, the spring 17 is compressed, and the screw 4 is fixed in the interlayer between the support plate 23 and the stop block 13. If it is necessary to remove the screw 4, the worker pushes the pull rod 16 outward, and the pull rod 16 drives the connecting rod 15 to move toward the outside of the fixed bin 9, further causing the stop block 13 to be stored in the movable groove 11. At this time, the screw 4 can be removed. After the screw 4 is fixed, the worker starts the driving mechanism 3, and the operation of the driving mechanism 3 drives The movable pressure plate 6 moves downward along the column 5 until the cold heading head 7 enters the interior of the fixed groove 10 and collides with the screw 4. The screw 4 is squeezed by the cold heading head 7, so that the screw 4 enters the interior of the rotating bin 18 and is shaped by the mold 19. When the screw 4 descends, the support plate 23 moves downward along the guide rod 22, and the spring three 24 is compressed. When the driving mechanism 3 drives the cold heading head 7 to reset, the support plate 23 uses the elastic potential energy of the spring three 24 to support the screw 4 to move upward and complete the reset operation.

When the screw 4 drops, the support plate 23 moves downward along the guide rod 22, and the spring three 24 is compressed. When the driving mechanism 3 drives the cold heading head 7 to reset, the support plate 23 uses the elastic potential energy of the spring three 24 to support the screw 4 to move upward to complete the reset operation.

[0040] By setting the spring three 24, the support plate 23 is always subjected to an upward force and conflicts with the screw 4. Compared with the traditional device, the device fixes the screw 4 by setting the reset mechanism, and after the screw 4 is processed, the elastic potential energy of the spring three 24 is used to support the screw 4 to move upward to complete the reset operation, which is convenient for removing the screw 4 and reduces the workload.

The screw 4 is squeezed by the cold heading head 7, so that the screw 4 enters the interior of the rotating chamber 18 and is shaped by the mold 19.

At this time, the downward movement of the screw 4 will squeeze the stop block 13, and the squeezing of the stop block 13 drives the movable plate 12 to move toward the inside of the movable groove 11. At this time, the spring 17 is compressed, and the screw 4 is fixed in the interlayer between the support plate 23 and the stop block 13. If it is necessary to remove the screw 4, the worker pushes the pull rod 16 outward, and the pull rod 16 drives the connecting rod 15 to move toward the outside of the fixed bin 9, further causing the stop block 13 to be stored in the movable groove 11. At this time, the screw 4 can be removed. After the screw 4 is fixed, the worker starts the driving mechanism 3, and the operation of the driving mechanism 3 drives The movable pressure plate 6 moves downward along the column 5 until the cold heading head 7 enters the interior of the fixed groove 10 and collides with the screw 4. The screw 4 is squeezed by the cold heading head 7, so that the screw 4 enters the interior of the rotating bin 18 and is shaped by the mold 19. When the screw 4 descends, the support plate 23 moves downward along the guide rod 22, and the spring three 24 is compressed. When the driving mechanism 3 drives the cold heading head 7 to reset, the support plate 23 uses the elastic potential energy of the spring three 24 to support the screw 4 to move upward and complete the reset operation. At this time, the staff can start the motor 20 to rotate the rotating bin 18, and the staff can move the mold 19 to the bottom of the screw 4 by rotating the rotating bin 18 to complete the replacement of the mold 19. At this time, the staff repeats the above operations to complete the molding of the screw 4.
