Description

Technical Field

[0001] This utility model belongs to the field of fastener manufacturing technology, specifically relating to a wear-resistant material distribution disc. Background Technology

[0002] The tail-cutting machine is a key piece of equipment used to process the tail of semi-finished screws to form drill tails. The feeding disc is an important feeding component of the equipment. Multiple feeding ports are evenly opened on its outer circumference. Semi-finished screws are fed into these feeding ports in an orderly manner through feeding mechanisms such as vibrating discs. As the feeding disc rotates, the semi-finished products are precisely transported to the drill tail forming mold for tail-cutting processing.

[0003] However, during production, the feeding port of the feed tray experiences continuous friction and impact with the semi-finished screws, causing wear, deformation, and even chipping at the edge of the feeding port. Wear on the feeding port reduces the positioning accuracy of the semi-finished screws within it, leading to feeding jams or inaccurate positioning, affecting the accuracy of subsequent tail-cutting and product quality consistency. Severely worn feed trays require replacement, increasing equipment maintenance costs and reducing production efficiency.

[0004] Therefore, the above problems urgently need to be solved. Utility Model Content

[0005] Purpose of the utility model: To overcome the above shortcomings, this utility model provides a wear-resistant dispensing disc. The original one-piece dispensing disc is designed as a detachable structure. When the dispensing port's performance deteriorates due to wear, only the dispensing ring needs to be replaced to restore function, avoiding the scrapping of the entire disc and significantly reducing equipment maintenance costs and production downtime. Simultaneously, wear-resistant blocks set on the inner wall of the dispensing port improve its wear resistance and extend the service life of the dispensing ring.

[0006] Technical Solution: To achieve the above objectives, this utility model provides a wear-resistant material distribution disc, including a main disc body and a material distribution ring detachably connected to the outer periphery of the main disc body. The outer periphery of the material distribution ring is evenly provided with material distribution openings for accommodating semi-finished workpieces. Wear-resistant blocks are provided on the inner sidewalls of the material distribution openings to improve their wear resistance. This utility model is installed on a screw cutting machine for screw cutting. This utility model redesigns the original one-piece material distribution disc into a detachable structure, including the main disc body and the material distribution ring. When the performance of the material distribution opening deteriorates due to wear, only the material distribution ring needs to be replaced to restore its function, avoiding the scrapping of the entire disc body and significantly reducing equipment maintenance costs and production downtime. Simultaneously, the wear-resistant blocks fixed to the inner sidewalls of the material distribution openings improve the wear resistance of the openings and extend the service life of the material distribution ring.

[0007] Furthermore, in the aforementioned wear-resistant distribution disc, a limiting protrusion is provided at the upper end of the outer periphery of the main disc body. A limiting groove is provided at the upper end of the inner side of the distribution ring. The limiting protrusion and the limiting groove cooperate to restrict the connection position between the main disc body and the distribution ring. The main disc body is connected to multiple locking mechanisms, which are arranged in an array around the center of the main disc body. The locking mechanism includes a locking block and a fastener threadedly connected to the locking block. By restricting the connection between the main disc body and the distribution ring through the cooperation of the limiting protrusion and the limiting groove, the locking mechanism locks the main disc body and the distribution ring, improving the stability and reliability of the connection.

[0008] Furthermore, in the aforementioned wear-resistant distribution disc, the locking block has a cam-shaped cross-section. A protrusion is located at the distal end of the locking block near the distribution ring. When locking the distribution ring, the distal end of the locking block is rotated to the lower end of the distribution ring, and the fastener is tightened. The protrusion and the distribution ring abut against each other, increasing the clamping force and ensuring that the main disc and the distribution ring do not shift during rotation.

[0009] Furthermore, in the aforementioned wear-resistant distribution disc, the outer wall of the main disc body is provided with external threads, and the inner wall of the distribution ring is provided with internal threads that match the external threads of the main disc body. The main disc body and the distribution ring are detachably connected by threads. The threaded connection structure of the main disc body and the distribution ring facilitates quick disassembly and assembly of the distribution ring. When the distribution port is severely worn, only the distribution ring needs to be unscrewed for replacement, without disassembling the main disc body, significantly shortening equipment maintenance time and reducing spare parts costs. At the same time, the threaded connection ensures the coaxiality of the connection, ensuring that the distribution ports are evenly distributed along the outer circumference of the main disc body, improving the stability of feeding.

[0010] Furthermore, in the aforementioned wear-resistant distribution disc, the external thread of the main disc is a left-hand thread. When the distribution disc rotates in the working direction (clockwise), the force on the threaded connection is in the tightening direction, thereby utilizing the inertia during operation to achieve automatic anti-loosening and improve the reliability and safety of the connection.

[0011] Furthermore, in the aforementioned wear-resistant distribution disc, the distribution port is designed as an arc-shaped groove. The connecting surface of the wear-resistant block is designed as an arc shape that matches the distribution port. The wear-resistant block is provided with a slot for accommodating semi-finished workpieces. The wear-resistant block is made of a high-hardness material such as tungsten carbide or ceramic composite material.

[0012] Furthermore, in the aforementioned wear-resistant distribution disc, the groove cross-section is designed as a triangle. The triangular design of the groove can precisely engage the head of the screw semi-finished product, reducing sliding friction and impact damage, and significantly extending the service life of the distribution ring.

[0013] Furthermore, in the aforementioned wear-resistant distribution disc, a positioning boss is provided at the center of the main disc body. The main disc body has multiple through holes for locking and fixing, which are arranged around the outer periphery of the positioning boss. The positioning boss of the main disc body cooperates with the main shaft of the equipment to achieve quick centering and installation. The through holes are fixed by bolts, which enhances the overall structural rigidity and adapts to the high-load requirements of continuous production of the tail-cutting machine.

[0014] As can be seen from the above technical solution, this utility model has the following beneficial effects: The wear-resistant dispensing disc of this utility model, through its detachable dispensing ring design, allows for replacement of only the dispensing ring when the dispensing port's performance deteriorates due to wear, avoiding the scrapping of the entire disc and significantly reducing equipment maintenance costs and production downtime. The wear-resistant block is made of high-hardness materials such as tungsten carbide or ceramic composite materials, improving the wear resistance of the dispensing port and extending the service life of the dispensing ring.

[0017] Example 1 like Figure 1-3 The invention relates to a wear-resistant feeder disc, comprising a main disc body 1 and a feeder ring 2 detachably connected to the outer periphery of the main disc body 1. The feeder ring 2 has evenly spaced feed openings 21 for accommodating semi-finished workpieces. Wear-resistant blocks 22 are provided on the inner wall of the feed openings 21 to improve their wear resistance. This invention is installed on a screw cutting machine for screw cutting. The screw cutting machine feeds semi-finished screws into the feed openings 21 in an orderly manner via a vibrating disc or other feeding mechanism. As the main disc body 1 rotates, the semi-finished products are precisely conveyed one by one to the screw cutting die for cutting. This invention redesigns the original one-piece feeder disc into a detachable structure, including the main disc body and the feeder ring. When the feed openings experience performance degradation due to wear, only the feeder ring needs to be replaced to restore function, avoiding the scrapping of the entire disc body and significantly reducing equipment maintenance costs and production downtime. Meanwhile, wear-resistant blocks 22 are fixed to the inner wall of the material distribution port to improve the wear resistance of the material distribution port and extend the service life of the material distribution ring.

[0018] In this embodiment, a limiting protrusion 11 is provided at the upper outer periphery of the main disc body 1. A limiting groove 23 is provided at the upper inner side of the distributing ring 2. The limiting protrusion 11 and the limiting groove 23 cooperate to restrict the connection position between the main disc body 1 and the distributing ring 2. The main disc body 1 is connected to multiple locking mechanisms, which are arranged in an array around the center of the main disc body 1. The locking mechanism includes a locking block 31 and a fastener 32 threadedly connected to the locking block 31. By restricting the connection between the main disc body 1 and the distributing ring 2 through the cooperation of the limiting protrusion 11 and the limiting groove 23, the locking mechanism locks the main disc body 1 and the distributing ring 2, improving the stability and reliability of the connection.

[0019] In this embodiment, the locking block 31 has a cam-shaped cross-section. The far end of the locking block 31 is provided with a protrusion near the material distribution ring 2. When locking the material distribution ring 2, the far end of the locking block 31 is rotated to the lower end of the material distribution ring 2, and the fastener 32 is tightened. The protrusion and the material distribution ring 2 abut against each other, which enhances the clamping force and ensures that the main disc 1 and the material distribution ring 2 do not shift during rotation.

[0020] In this embodiment, the outer wall of the main disc 1 is provided with external threads, and the inner wall of the distribution ring 2 is provided with internal threads that are compatible with the external threads of the main disc 1. The main disc 1 and the distribution ring 2 are detachably connected by threads. The threaded connection structure of the main disc 1 and the distribution ring 2 facilitates quick disassembly and assembly of the distribution ring 2. When the distribution port 21 is severely worn, only the distribution ring 2 needs to be unscrewed for replacement, without disassembling the main disc 1, which greatly shortens the equipment maintenance time and reduces spare parts costs. At the same time, the threaded connection between the two ensures the coaxiality of the connection, ensuring that the distribution ports 21 are evenly distributed along the outer circumference of the main disc 1, and improving the stability of feeding.

[0021] In this embodiment, the external thread of the main disc 1 is a left-hand thread. When the dispensing disc rotates in the working direction (clockwise), the force on the threaded connection is in the tightening direction, thereby utilizing the inertia during operation to achieve automatic anti-loosening and improve the reliability and safety of the connection.

[0022] In this embodiment, the material distribution port 21 is designed as an arc-shaped groove. The connecting surface of the wear-resistant block 22 is designed as an arc shape that matches the material distribution port 21. The wear-resistant block 22 is provided with a slot 221 for accommodating semi-finished workpieces. The wear-resistant block 22 is made of a high-hardness material such as tungsten carbide or ceramic composite material.

[0023] In this embodiment, the cross-section of the slot 221 is triangular. The triangular design of the slot 221 can accurately engage the head of the screw semi-finished product, reduce sliding friction and impact damage, and significantly extend the service life of the material distribution ring 2.

[0024] In this embodiment, a positioning boss 12 is provided at the center of the main disc 1. The main disc 1 is provided with multiple through holes 13 for locking and fixing, and the through holes 13 are arranged around the outer periphery of the positioning boss 12. The positioning boss 12 of the main disc 1 cooperates with the main shaft of the equipment to achieve quick centering and installation. The through holes 13 are fixed by bolts to enhance the overall structural rigidity and adapt to the high load requirements of continuous production of the tail cutting machine.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the scope of protection of this utility model.
