Abstract
Description
Technical Field
[0001] This utility model relates to the field of thread rolling machine technology, specifically a high-efficiency thread rolling machine for screw production. Background Technology
[0002] In the screw manufacturing process, thread rolling machines are crucial equipment for machining the threads of screws. Currently, traditional thread rolling machines on the market have several significant drawbacks. After machining the screws, the processed screws often experience ejection at high speeds due to machine inertia and poorly designed ejection ports. This ejection not only damages or renders the processed screws unusable, wasting raw materials and increasing production costs, but also affects production continuity and efficiency. Furthermore, processing debris adheres to the surface of the processed screws during ejection. If not cleaned promptly, this debris can affect the quality of subsequent processes and even cause equipment malfunctions. Additionally, traditional thread rolling machines lack effective guiding structures for ejected screws, making the screw ejection process unstable and uncontrollable. Utility Model Content
[0003] To address the shortcomings of existing technologies, this utility model provides a high-efficiency thread rolling machine for screw production, thus solving the problems in the existing technology.
[0004] To achieve the above objectives, this utility model provides a high-efficiency thread rolling machine for screw production, comprising a machine body, with an inlet at the beginning and an outlet at the end. The machine body is equipped with a thread rolling mechanism for threading external screws to be processed. The inlet is equipped with a feeding mechanism for conveying external screws to be processed onto the machine body. It also includes an anti-throw hopper, which is positioned near the outlet and has an inlet hole for the processed screws discharged from the outlet to be moved or thrown in. The inlet hole faces the outlet, and the bottom of the inlet hole has an outlet hole for the processed screws in the inlet hole to move to the next processing equipment. The inlet hole is equipped with a guide structure for smoothly guiding the thrown processed screws into the outlet hole and a suction structure for cleaning debris from the processed screws in the inlet hole.
[0005] The advantages of adopting the above technical solution are as follows: The technology incorporates an anti-throw hopper with an inlet facing the outlet. This effectively catches the processed screws discharged from the outlet, preventing them from being thrown and colliding with surrounding equipment or components. This reduces damage or scrapping of processed bolts due to throwing, lowering raw material waste and production costs. Furthermore, a guiding structure within the inlet guides the thrown processed screws smoothly into the outlet, making the screw discharge process more stable and controllable, improving production continuity and efficiency. The suction structure within the outlet effectively cleans debris from the processed screws, preventing debris from affecting the quality of subsequent processes and ensuring product quality. It also reduces potential equipment malfunctions caused by debris, improving equipment stability and lifespan.
[0006] The present invention further comprises: the guiding structure including a guide plate disposed on the inner peripheral wall of the feed hole, the radial cross section of the guide plate being arc-shaped and the outer wall surface of the guide plate being connected to the inner peripheral wall of the feed hole in a smooth arc surface, the guide plate being concave in the direction of the inner peripheral wall of the feed hole, the bottom of the guide plate extending towards the end of the machine body and forming a leak-proof part for fitting against the bottom of the machine body, the leak-proof part being disposed near the discharge port and below the discharge port, and the discharge port being disposed between the leak-proof part and the guide plate.
[0007] The advantages of adopting the above technical solution are as follows: The radial cross-section of the guide plate is arc-shaped and connects smoothly with the inner circumferential wall of the feed hole. This design conforms to the trajectory of the thrown screws. With the guiding effect of the arc-shaped surface, the high-speed thrown processed screws are smoothly guided into the discharge hole, preventing damage from collisions with the inner wall of the feed hole. This effectively improves the stability of the discharge process and ensures continuous and efficient production. The leak-proof section extending from the bottom of the guide plate fits snugly against the bottom of the machine body and is located below the discharge port. This effectively blocks screws that fail to fall into the discharge hole in time for various reasons, preventing them from falling through the gap between the feed hole and the machine body, eliminating material leakage, reducing cleaning work on the production site, and maintaining a clean and orderly production environment. The discharge hole is located at a specific position between the leak-proof section and the guide plate. Combined with the structure of the guide plate and the leak-proof section, the processed screws are accurately guided into the discharge hole by the guide plate, avoiding screw accumulation or blockage caused by improper discharge hole positioning. This further optimizes the discharge process and improves the overall operating efficiency of the equipment.
[0008] The present invention is further provided that: the leak-proof part is connected to the inner peripheral wall of the discharge hole opening with a smooth arc surface, and the leak-proof part is located at an oblique position above the discharge hole.
[0009] The advantages of adopting the above technical solution are as follows: The leak-proof part and the inner circumferential wall of the discharge hole opening are connected by a smooth arc surface. This allows the processed screws to transition more naturally and smoothly as they move from the guide plate and leak-proof part to the discharge hole. The smooth connection effectively avoids screw jamming caused by structural abrupt changes, ensuring that the material can quickly and smoothly pass through the discharge hole into the next process, greatly improving discharge efficiency, reducing equipment downtime, and further ensuring production continuity. Simultaneously, the smooth arc surface connection reduces the possibility of material accumulation and residue at the connection point. The leak-proof part is positioned diagonally above the discharge hole, working in conjunction with the guide plate to provide a precise guiding path for the processed screws. By optimizing the discharge path and reducing abnormal material dwell and collisions inside the equipment, the product is better protected during the discharge process.
[0010] The present invention further includes: an elastic soft pad is laid on the outer wall surface of the guide plate.
[0011] The advantages of adopting the above technical solution are: the presence of the elastic soft pad in the above technology provides a buffer layer between the processed screw and the guide plate. When the flying screw hits the guide plate, the elastic soft pad can effectively absorb the impact force and prevent the screw surface from being scratched, dented or damaged by the hard impact. This greatly improves the protection effect of the product during the unloading process, ensures stable product quality, improves the product yield, and reduces the risk of increased production costs due to product damage.
[0012] The present invention further comprises: the suction structure including a plurality of suction holes, all of which are opened at the bottom of the feed hole and are evenly distributed in a circumferential manner along the outer edge of the discharge hole; the anti-throwing hopper is hollow and has a negative pressure chamber; the plurality of suction holes are all connected to the negative pressure chamber; the suction structure also includes a suction nozzle for connecting to the suction end of an external air pump; the suction nozzle is located at the bottom of the anti-throwing hopper and the suction nozzle is connected to the negative pressure chamber.
[0013] The advantages of adopting the above technical solution are as follows: In the above technology, several suction holes are evenly distributed around the bottom of the feed hole and along the outer edge of the discharge hole. By connecting the suction holes with the negative pressure chamber and setting a suction nozzle connected to an external air pump, a stable negative pressure suction system is formed. This allows the surface and surrounding debris of the processed screw to be suctioned and cleaned in an all-round and efficient manner during the discharge process. Because the suction holes are evenly distributed, no matter what angle the screw enters the feed hole, the surrounding debris can be quickly sucked into the negative pressure chamber, avoiding debris adhering to the screw surface and affecting the next process. This effectively ensures product quality and reduces the defect rate.
[0014] The present invention further includes the following: the suction structure includes several air outlets, which are evenly distributed on the top of the feed hole and facing the discharge hole; the anti-throw hopper is hollow and has an air cavity, and the air outlets are all connected to the air cavity; the suction structure also includes an air inlet for connecting to an external air pump to inject high-speed gas into the air cavity, and the air inlet is located on the top of the anti-throw hopper and is connected to the air cavity.
[0015] The advantages of adopting the above technical solution are as follows: The air outlets, evenly distributed at the top of the feed hole and facing the discharge hole, combined with the air inlet and air chamber connected to an external air pump, can inject high-speed gas into the feed hole. This high-speed airflow can sweep the surface of the processed screws and the inside of the feed hole, quickly blowing off stubborn debris that might have adhered to the screws or accumulated in the corners of the feed hole. This, along with the suction hole at the bottom, forms a coordinated cleaning mechanism, greatly improving the efficiency of debris removal, ensuring a cleaner product surface, and further guaranteeing the processing quality of the next process. The injection of high-speed gas can change the airflow environment inside the feed hole, preventing debris from forming localized accumulation or adhesion. Through continuous airflow circulation, not only can the cleaned debris be quickly carried out, but corrosion or wear of internal equipment components caused by debris residue can also be avoided.
