Description

Technical Field

[0001] The utility model relates to the technical field of screw stamping dies, in particular to a stamping die for producing thin plate connecting screws. Background Art

[0002] A thin plate is a flat cross-section plate with a large ratio of width to thickness. Thin plates are usually used in the construction industry and the machinery industry. When processing and using thin plates, screws are needed to fix and install them. Screws are tools that use the physics and mathematical principles of the circular rotation of the inclined surface of an object and the friction force to gradually tighten objects and parts.

[0003] When the screws are processed and produced, a stamping die is needed to stamp the top notch. For example, a self-tapping screw stamping die is proposed in Chinese patent CN220679265U. After the metal wire falls into the blanking funnel, it falls into the mold core and automatically loads the material, which further improves the work efficiency.

[0004] In the above scheme, the screws are fed and punched through a funnel and an arc groove, but the two ends of the screw are usually not aligned, which may cause the small end of the screw to be on top before feeding, resulting in screw punching failure and reduced yield rate.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] The utility model provides a technical solution, please refer to Figure 1 and Figure 2 A stamping die for producing thin plate connecting screws includes: a base 1, a stamping machine unit 2 and a feeding mechanism 3. The stamping machine unit 2 is a common stamping machine in the prior art, which can perform stamping processing on the screws. The base 1 can support the stamping mechanism 4. The feeding mechanism 3 can feed the screws. The feeding mechanism 3 includes a feeding pipe 31 and a funnel 32. The feeding pipe 31 and the funnel 32 are assembled on the top of the base 1 through a vertical arm 35. A transverse groove is also provided on the top of the feeding pipe 31. The transverse groove can clamp the screw inside and slide inside the feeding pipe 31 to increase the stability of the screw during feeding. The funnel 32 can guide the screw to fall into the inside of the stamping groove 42.

[0026] A single-axis driving unit 33 is installed on the top of the base 1, and a sealing plate 34 is installed on the bottom of the single-axis driving unit 33. The single-axis driving unit 33 is a common electric single-axis driver in the prior art, which can drive the sealing plate 34 to move, and the sealing plate 34 can close the bottom of the funnel 32. The punching unit 2 and the feeding mechanism 3 are both arranged on the top of the base 1. A punching mechanism 4 is installed on the top of the base 1. The punching mechanism 4 includes a disc 41 and a curved slope 44. The disc 41 can drive the screw to move, and the curved slope 44 can drive the discharging mechanism 5 to move. The top of the disc 41 is evenly provided with punching grooves 42, which can accommodate the screws, and the punching grooves 42 are adapted to the screws.

[0027] The inside of the stamping groove 42 is equipped with a discharge mechanism 5, and the bottom of the disc 41 is connected to a motor group 43, which is a servo motor commonly used in the prior art and can drive the disc 41 to move. The motor group 43 is connected to the base 1, and the curved slope 44 is installed on the top right side of the base 1. The top of the base 1 is equipped with an annular groove block 46, and sliders 45 are evenly arranged on the top of the annular groove block 46. The sliders 45 are connected to the disc 41. The annular groove block 46 cooperates with the slider 45 to guide the disc 41 to move in a circular motion, thereby increasing the stability of the disc 41 during movement and processing.

[0028] See also Figure 3 and Figure 4 The discharging mechanism 5 includes a top plate 51. The bottom of the top plate 51 can also be equipped with a cylinder. The top plate 51 is controlled by the cylinder to move up and down to discharge the material. The top plate 51 can push out the screws. The top plate 51 is slidably arranged inside the stamping groove 42. Springs 52 are evenly arranged at the bottom of the top plate 51. The springs 52 can drive the top plate 51 to return after movement. The bottom of the spring 52 is connected to a limit plate 53, and the limit plate 53 is connected to the stamping groove 42.

[0029] A curved push block 7 is connected to the left side of the top of the base 1, and a trapezoidal push block 6 is installed on the right side of the top of the base 1. Collection boxes 11 are installed at both ends of the top of the base 1. The two collection boxes 11 are respectively arranged on the outside of the trapezoidal push block 6 and the curved push block 7. The collection boxes 11 can collect screws. The bottom of the trapezoidal push block 6 and the left side of the curved push block 7 are both curved designs, and the outside of the trapezoidal push block 6 and the curved push block 7 are wrapped with protective covers. The trapezoidal push block 6 and the curved push block 7 can both guide the screws through the curves.

[0030] In this scheme, the screw is placed inside the feeding tube 31, and the single-axis driving unit 33 is started to drive the sealing plate 34 to move to release the closure of the funnel 32. The screw enters the inside of the stamping groove 42 through the guidance of the funnel 32, and the motor unit 43 is started to drive the disc 41 to rotate. The disc 41 drives the screw to move. If the big head of the screw is facing downward, the screw cannot fall into the inside of the stamping groove 42. At this time, the disc 41 drives the screw that cannot enter the stamping groove 42 to collide with the curved push block 7 during rotation, thereby causing the screw to fall into the collection box 11. When the screw falls into the inside of the stamping groove 42 normally, the stamping groove 42 moves to the bottom of the stamping unit 2 and stops rotating. The stamping unit 2 is started to stamp the screw. When the screw moves to the top of the curved slope 44, the curved slope 44 rises through its gradually raised plane against the top plate 51, and then pushes the screw out. The screw touches the trapezoidal push block 6 and is guided by the inclined surface of the trapezoidal push block 6 and discharged into the collection box 11 for collection.

[0031] Before the screws are punched, the position of the screws is automatically detected through the cooperation of the added punching mechanism 4 and the curved push block 7, and the screws that have not completely entered the punching groove 42 are removed, so as to avoid unnecessary losses caused by the inability to process the screws normally and to avoid reducing the yield of the screws. At the same time, after the punching process of the screws is completed, the added trapezoidal push block 6 and the discharge mechanism 5 are used to automatically discharge and feed the screws, thereby reducing the operating steps of the device, improving the processing speed of the screws, and saving energy loss.
