Description

Technical Field

[0001] This invention relates to the field of gear processing technology, specifically to a blank rod conveying and punching device and method for gear processing. Background Technology

[0002] In the field of gear processing, the preparation of blank rods is a fundamental step to ensure the accuracy and efficiency of subsequent finishing. Traditional blank rod processing usually involves the conveying and fixed-length punching of long strip metal raw materials.

[0003] However, existing punching equipment still faces many technical bottlenecks in actual production: First, during the punching process, the intense friction between the tool and the metal material generates a large amount of cutting heat. Existing equipment cannot effectively cool the punching tool in a timely manner. The tool is prone to "annealing" due to excessive temperature, which leads to a decrease in tool hardness and increased wear. This not only shortens the tool's service life but also affects the smoothness and precision of the punched surface due to increased frictional resistance. Furthermore, if the metal chips generated during the punching process are not removed in time, they are prone to adhering to the tool edge or die surface, causing secondary scratches or accelerated wear. Summary of the Invention

[0015] Compared with the prior art, the present invention provides a blank rod conveying and punching device and method for gear processing, which has the following beneficial effects: 1. This blank rod conveying and punching equipment for gear processing utilizes the negative pressure and compression generated by the lifting and lowering motion of the punching seat to automatically draw coolant from the cooling water tank and drip it onto both sides of the punching blade. This not only removes cutting heat and prevents tool annealing, but also forms a lubricating film to reduce frictional resistance.

[0016] 2. This blank rod conveying and punching equipment for gear processing returns the chips and coolant generated during punching to the cooling water tank through the punching groove and return chamber. After being separated by the inclined filter plate, the coolant can rejoin the cooling cycle, greatly reducing coolant loss and waste liquid treatment costs. The chips are collected and retained on the filter plate, which is convenient for regular cleaning and recycling, avoiding chip accumulation that could damage the equipment or scatter and pollute the workshop. This achieves efficient utilization of resources and orderly treatment of waste.

[0017] 3. This blank rod conveying and punching equipment for gear processing achieves sequential feeding of long rod-shaped raw materials through the coordinated action of a rotary cylinder, a material distribution wheel, and a material clamping groove, avoiding multiple raw materials entering simultaneously and causing punching overload. Combined with a cover plate to seal the conveying area before punching, it effectively suppresses the rebound and arching of the raw material caused by internal stress, ensuring the positional accuracy of the raw material during conveying and punching. Simultaneously, it protects the conveying components and punching tools from damage caused by abnormal loads, improving processing stability and equipment lifespan. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example 1: Reference Figures 1-8 A blank rod conveying and punching equipment for gear processing includes a conveying chamber 1 and a punching chamber 2. The conveying chamber 1 and the punching chamber 2 are fixedly connected by a guide pipe 3. The equipment also includes: a material placement rack 4, which is provided in multiple sets and fixed at equal intervals in the conveying chamber 1. Each set of material placement racks 4 has a storage rack 41 installed at its end. A rotary cylinder 42 is fixedly connected to the side wall of each set of material placement racks 4. The storage rack 41 is fixedly connected to the extension end of the rotary cylinder 42. The multiple sets of rotary cylinders 42 operate synchronously. A material distribution part is installed on the side wall of the conveying chamber 1 below the storage rack 41; a conveying assembly, which is installed in the conveying chamber 1 and is used to convey long rod-shaped raw materials to the punching chamber 2; and a punching assembly, which is installed in the punching chamber 2 and is used to punch the long rod-shaped raw materials conveyed to the punching chamber 2.

[0023] Reference Figures 1-3The conveying assembly includes a conveying box 5, which is fixedly connected to the bottom of the inner cavity of the conveying chamber 1. A conveying guide groove 51 is provided on the top of the conveying box 5, and the output end of the conveying guide groove 51 is aligned with and connected to the guide pipe 3. A driving cavity 52 is provided at the bottom of the conveying box 5, and a reciprocating screw 53 is rotatably connected within the driving cavity 52. ​​A sliding block 54 is threaded onto the reciprocating screw 53. A pusher plate 55 is slidably connected within the conveying guide groove 51. Limiting guide grooves 57, which communicate with the driving cavity 52, are provided on both sides of the conveying guide groove 51. Limiting guide plates 571 are slidably connected within both limiting guide grooves 57, and the two ends of the limiting guide plates 571 are fixedly connected to the corresponding sliding block 54 and pusher plate 55, respectively. A feeding motor 56 is fixedly connected to the bottom of the conveying chamber 1, and the feeding motor 56 is connected to the reciprocating screw 53 via a rubber band. The material distribution section includes a guide plate 6, which is provided in multiple sets. The multiple sets of guide plates 6 are fixed at equal intervals on the side wall of the conveying chamber 1. The top of the guide plate 6 is designed to be inclined, and the inclined bottom end is attached to the side wall of the conveying box 5. That is, the long rod-shaped raw material sliding along the inclined top of the guide plate 6 will slide into the conveying guide groove 51. Among them, the multiple sets of guide plates 6 are rotatably connected to the material distribution rod 61. Both ends of the material distribution rod 61 are fixedly connected to the material distribution wheel 62, and the top of the material distribution wheel 62 is higher than the inclined top of the guide plate 6. The material distribution wheel 62 has multiple sets of material clamping grooves 63, and the material clamping grooves 63 on the two sets of material distribution wheels 62 are symmetrically arranged along the center of the material distribution rod 61. The inner wall of the conveying chamber 1 is fixedly connected to the material distribution motor 64, and the output end of the material distribution motor 64 is fixedly connected to the end of the material distribution rod 61.

[0024] With the above-described structure, multiple long, rod-shaped raw materials are manually placed onto multiple sets of storage racks 41. The entire equipment then starts. First, multiple sets of rotary cylinders 42 operate synchronously, causing the storage racks 41 to rotate downwards, thus tilting the guide plate 6. At this time, some of the long, rod-shaped raw materials will slide down the tilted storage racks 41 onto the guide plate 6 under gravity. Then, the multiple sets of rotary cylinders 42 synchronously reset and rotate. After the raw materials on the guide plate 6 have been completely conveyed, the rotary cylinders 42 rotate again to unload the material, avoiding excessive material loading at once and improving the protection of subsequent conveying components. After the raw materials slide onto the guide plate 6, the dispensing motor 6... 4. The material distribution rod 61 and the material distribution wheels 62 on both sides rotate, so that the raw material enters the material clamping groove 63. As the material distribution wheel 62 rotates, the raw material will move along the material distribution wheel 62 to the other side of the guide plate 6, and slide out of the material clamping groove 63 under the action of gravity, and slide along the guide plate 6 into the material conveying guide groove 51. Each time a raw material rolls off the material distribution wheel 62, the material distribution motor 64 stops, thus completing the feeding of a single raw material and avoiding overload in subsequent punching. Then, the feeding motor 56 is turned on, so that it drives the reciprocating screw 53 to rotate, so that the sliding block 54 carries the pusher plate 55 along the reciprocating screw 53 to move towards the punching chamber 2, and thus pushes the raw material through the guide pipe 3 into the punching bucket 81 in the punching chamber 2. In addition, after a single feeding is completed, the reciprocating screw 53 continues to rotate, and the sliding block 54 will move in the opposite direction along the reciprocating screw 53. When the sliding block 54 moves to the initial position of pushing the material, the feeding of the single rod material will continue again, thereby realizing the continuous supply of single raw materials and effectively improving processing efficiency.

[0025] Reference Figure 1 A rotating shaft 7 is rotatably connected inside the conveying chamber 1. Mounting parts 71 are fixedly connected to both sides of the rotating shaft 7. A cover plate 72 is fixedly connected between the two sets of mounting parts 71. A flip-top motor 73 is fixedly connected inside the conveying chamber 1. The output shaft of the flip-top motor 73 is fixedly connected to the rotating shaft 7. The cover plate 72 is adapted to the material box 5. That is, when the rotating shaft 7 rotates, the top opening of the material box 5 is closed or opened.

[0026] With the above structure, the flip-top motor 73 drives the rotating shaft 7 to rotate, which in turn drives the cover plate 72 to rotate, causing the cover plate 72 to disengage from the top of the feeding box 5, thus opening the feeding box 5. When a single raw material enters the feeding guide trough 51, the flip-top motor 73 drives the rotating shaft 7 to rotate in the opposite direction, causing the cover plate 72 to seal the feeding box 5, thus preventing the raw material from rebounding and arching due to its internal stress during the subsequent punching process, and ensuring the safety of the raw material conveying area.

[0027] Reference Figure 4 , Figure 5 , Figure 7 and Figure 8 The punching assembly includes a support plate 8, with a punching hopper 81 fixedly connected to the top of the support plate 8. The output end of the guide pipe 3 extends into the punching hopper 81, and the inner cavity of the output end of the guide pipe 3 is flush with the bottom of the inner cavity of the punching hopper 81. That is, the long rod-shaped raw material discharged from the output end of the guide pipe 3 slides along the bottom of the inner cavity of the punching hopper 81. A crankshaft 82 is rotatably connected inside the punching chamber 2. A punching seat 83 is hinged to the middle of the crankshaft 82 through a connecting rod. A punching blade 84 is fixedly connected to the bottom of the punching seat 83. A punching motor 85 is fixedly connected to the inner wall of the punching chamber 2. The punching motor 85 and the crankshaft 82 are connected by a belt pulley group. Positioning guide grooves 86 are opened on both sides of the support plate 8. Positioning guide plates 861 are slidably connected in the positioning guide grooves 86. A limit guide rod 862 is fixedly connected to the top of the positioning guide plate 861. The other end of the limit guide rod 862 is connected to the side wall of the punching seat 83.

[0028] With the above structure, when the rod material enters the punching bucket 81, the punching motor 85 is turned on, which drives the crankshaft 82 to rotate. At the same time, it drives the punching seat 83 and the punching blade 84 to reciprocate up and down in the vertical direction, thereby continuously punching the rod material moving along the punching bucket 81, which effectively improves the punching efficiency. Furthermore, the positioning guide groove 86, the positioning guide plate 861, and the limiting guide rod 862 limit the movement direction of the punching blade 84, ensuring that it moves stably up and down in the vertical direction.

[0029] Reference Figures 4-8 A cooling water tank 87 is provided inside the support plate 8. An inclined filter plate 871 is fixedly connected inside the cooling water tank 87. The bottom of the positioning guide groove 86 is fixed and connected to a suction pipe 872. The bottom end of the suction pipe 872 passes through the inclined filter plate 871 and extends to the bottom of the cooling water tank 87. A liquid guiding groove 831 is provided inside the punching seat 83. A liquid filling groove 863 is provided inside the limiting guide rod 862. The two ends of the liquid filling groove 863 are respectively connected to the inner cavity of the positioning guide groove 86 and the liquid guiding groove 831. A one-way valve is provided in both the suction pipe 872 and the liquid filling groove 863. Multiple cooling grooves 832 facing the side wall of the punching blade 84 are provided at the bottom of the liquid guiding groove 831. It should be noted that the one-way valve in the suction pipe 872 can only allow the liquid in the cooling water tank 87 to enter the positioning guide groove 86; the one-way valve in the filling tank 863 can only allow the liquid in the positioning guide groove 86 to enter the liquid guiding groove 831.

[0030] With the above-described structure, when the raw material enters the punching hopper 81, the punching motor 85 is activated, causing the crankshaft 82 to rotate. Simultaneously, the punching seat 83 and the punching blade 84 reciprocate vertically, thus punching the raw material moving along the punching hopper 81. During the upward movement of the punching seat 83, the positioning guide plate 861 slides upward along the positioning guide groove 86, creating a negative pressure suction within the positioning guide groove 86. This opens the one-way valve in the suction pipe 872, allowing the coolant in the cooling water tank 87 to flow into the positioning guide groove 86 through the suction pipe 872. Then, as the punching seat 83, carrying the positioning guide plate 861, slides downward within the positioning guide groove 86, it compresses the coolant sucked into the positioning guide groove 86 and opens the one-way valve in the filling tank 863, allowing the coolant to flow into the guiding tank 831 through the filling tank 863, and finally drips down the cooling tank 832. The coolant falls to both sides of the punching cutter 84, thus carrying away the cutting heat generated by the punching cutter 84 during repeated punching, preventing the punching cutter 84 from "annealing" due to excessive temperature, and forming a lubricating film on the punching cutter 84, effectively reducing the friction generated during punching, thereby maintaining the sharpness and durability of the punching cutter 84; and the continuously flowing coolant can wash away the small metal chips generated during punching, preventing the chips from adhering to the punching cutter 84 or the punching groove 811, reducing the possibility of chips scratching the raw material and wearing the punching cutter 84, thereby improving the punching quality and the durability of the punching cutter 84.

[0031] Reference Figures 4-7 The bottom of the inclined section of the punching bucket 81 is fixed and connected to the support plate 8, and a return chamber 9 is connected to it. The connection between the return chamber 9 and the cooling water tank 87 is located above the inclined filter plate 871. The top of the return chamber 9 is fixedly connected to the connection between the punching bucket 81 and the top of the punching bucket 81, and the filter plate 91 is flush with the inclined section of the punching bucket 81. The bottom of the inner cavity of the punching bucket 81, which is located directly below the punching knife 84, is provided with a punching groove 811. The inner wall of the punching groove 811 and the outer wall of the punching knife 84 form a gap for punching and chip removal to ensure smooth punching and effective chip removal. The bottom of the punching groove 811 is connected to the top of the inner cavity of the cooling water tank 87.

[0032] With the above-described structure, the continuously flowing liquid carries debris through the punching groove 811 into the cooling water tank 87, while the punched metal parts slide down the punching bucket 81. When the metal parts pass the filter plate 91, the debris and water adhering to the metal parts can be further removed, allowing the debris and water to flow back into the cooling water tank 87 through the return chamber 9. As described above, the coolant and punching debris will eventually enter the cooling water tank 87 and be filtered by the inclined filter plate 871. The coolant will then participate in subsequent cooling operations, thereby achieving the recycling of coolant, effectively reducing coolant loss, lowering production costs, and collecting the debris generated during punching to prevent debris accumulation inside the equipment. This also effectively prevents cutting fluid splashing and debris scattering, keeping the workshop floor dry and clean, and effectively improving the workshop environment.

[0033] Reference Figure 5 In addition, a slag discharge trough is provided on the side wall of the cooling water tank 87 located above the inclined filter plate 871, and a sealing plate is fixedly connected to the slag discharge trough; in this way, the metal debris trapped on the inclined filter plate 871 can be removed by periodically disassembling the sealing plate, thereby improving the convenience of equipment maintenance.

[0034] Example 2: Reference Figures 1-8 Similar to Example 1, but based on Example 1, a method for conveying and punching a blank rod for gear processing is proposed, including the following steps: Step 1: Transfer the long, rod-shaped raw materials stacked on the storage rack 41 one by one into the material conveying box 5; Step 2: Push the raw material in the feed box 5 into the punching hopper 81 and punch the raw material; Step 3: During the punching process, continuously drip coolant onto the punching blade 84; Step 4: Recycle the coolant for reuse, and at the same time remove and collect the debris generated during the punching process.

[0035] Reference Figures 1-8 In this invention, during use, multiple long rod-shaped raw materials are manually placed on multiple sets of storage racks 41. Then, the entire equipment is started. First, multiple sets of rotary cylinders 42 operate synchronously, driving the storage racks 41 to rotate downwards, causing the entire storage rack 41 to become an inclined state of the guide plate 6. At this time, some of the long rod-shaped raw materials will slide down the inclined storage racks 41 onto the guide plate 6 under the action of gravity. Then, multiple sets of rotary cylinders 42 synchronously reset and rotate. After the raw materials on the guide plate 6 have been conveyed, the rotary cylinders 42 rotate again to unload the material, so as to avoid excessive material unloading at one time, which would lead to excessive load and improve the protection of subsequent conveying components.

[0036] At the same time, the flip-top motor 73 drives the rotating shaft 7 to rotate, causing the cover plate 72 to rotate, thus disengaging the cover plate 72 from the top of the feeding box 5, opening the feeding box 5. When the raw material slides onto the guide plate 6, the distributing motor 64 drives the distributing rod 61 and its two side distributing wheels 62 to rotate, allowing the raw material to enter the clamping groove 63. As the distributing wheels 62 rotate, the raw material will move along the distributing wheels 62 to the other side of the guide plate 6, and under the action of gravity, slide out of the clamping groove 63 and along... The guide plate 6 slides into the feeding guide trough 51, and the feeding motor 64 stops each time a piece of raw material rolls off the feeding wheel 62, thus completing the feeding of a single piece of raw material and avoiding overload in subsequent punching. After a single piece of raw material enters the feeding guide trough 51, the flip-top motor 73 drives the rotating shaft 7 to rotate in the opposite direction, causing the cover plate 72 to seal the feeding box 5, preventing the raw material from rebounding and arching due to its internal stress during subsequent punching, thus ensuring the safety of the raw material feeding area. Subsequently, the feeding motor 56 is turned on, which drives the reciprocating screw 53 to rotate, causing the sliding block 54 to move along the reciprocating screw 53 towards the punching chamber 2 with the pusher plate 55, thereby pushing the raw material through the guide pipe 3 into the punching hopper 81 in the punching chamber 2. In addition, after a single feeding is completed, the reciprocating screw 53 continues to rotate, and the sliding block 54 will move in the opposite direction along the reciprocating screw 53. When the sliding block 54 moves to the initial position of pushing the material, the feeding of the single rod material will continue again, thereby realizing the continuous supply of single raw materials and effectively improving processing efficiency.

[0037] When the raw material rod enters the punching hopper 81, the punching motor 85 is turned on, causing the crankshaft 82 to rotate. Simultaneously, the punching seat 83 and the punching blade 84 reciprocate vertically, thus punching the raw material rod moving along the punching hopper 81. During the upward movement of the punching seat 83, the positioning guide plate 861 slides upward along the positioning guide groove 86, creating a negative pressure suction within the positioning guide groove 86. This opens the one-way valve in the suction pipe 872, allowing the coolant in the cooling water tank 87 to flow into the positioning guide groove 86. Then, as the punching seat 83, carrying the positioning guide plate 861, slides downward within the positioning guide groove 86, it compresses the coolant sucked into the positioning guide groove 86 and opens the one-way valve in the filling tank 863, allowing the coolant to flow into the guiding tank 831 along the filling tank 863, and finally drips down the cooling tank 832. The coolant falls to both sides of the punching cutter 84, thus carrying away the cutting heat generated by the punching cutter 84 during repeated punching, preventing the punching cutter 84 from "annealing" due to excessive temperature, and forming a lubricating film on the punching cutter 84, effectively reducing the friction generated during punching, thereby maintaining the sharpness and durability of the punching cutter 84; and the continuously flowing coolant can wash away the small metal chips generated during punching, preventing the chips from adhering to the punching cutter 84 or the punching groove 811, reducing the possibility of chips scratching the raw material and wearing the punching cutter 84, thereby improving the punching quality and the durability of the punching cutter 84.

[0038] Subsequently, the continuously flowing liquid carries debris through the punching groove 811 into the cooling water tank 87, while the punched metal parts slide down the punching bucket 81. When the metal parts pass through the filter plate 91, the debris and water adhering to the metal parts are further removed, allowing the debris and water to flow back into the cooling water tank 87 through the return chamber 9. As described above, the coolant and punching debris will eventually enter the cooling water tank 87 and be filtered by the inclined filter plate 871. The coolant will then participate in subsequent cooling operations, thereby achieving the recycling of coolant, effectively reducing coolant loss, lowering production costs, and collecting the debris generated during punching to prevent debris accumulation inside the equipment. This also effectively prevents cutting fluid splashing and debris scattering, keeping the workshop floor dry and clean, and effectively improving the workshop environment.
