Description

Technical Field

[0001] The invention relates to the field of thread rolling machines, and more particularly to a thread rolling machine capable of automatically loading and unloading materials. Background Art

[0002] The working principle of the thread rolling machine is to use pressure to compress the metal material into a thread shape. Under the pressure of the thread rolling machine, the workpiece is stuck between two or three guide wheels. Through the rotation and movement of the guide wheels, the pressure gradually increases, causing the metal material on the surface of the workpiece to undergo plastic deformation and eventually form a precise thread. There are many types of thread rolling machines, including fixed and through-type. The fixed type can be equipped with a vibration plate if the size permits, to achieve full automation; the drum type is suitable for processing workpieces with longer lengths. When choosing a thread rolling machine, it is necessary to comprehensively consider factors such as specific processing requirements, workpiece material and size.

[0003] For thread rolling machines with a high degree of automation, they are usually equipped with an automatic feeding and discharging system. The workpiece can be automatically moved forward and accurately fed into the processing area of ​​the thread rolling machine, and the workpiece is automatically fed out after the processing is completed. However, for some manually operated or less automated thread rolling machines, the workpiece may need to be manually fed in and taken out. In this case, the operator needs to manually place the workpiece on the feed port or pallet of the thread rolling machine according to the processing requirements, and manually take out the workpiece after the processing is completed. However, longer workpieces need to be supported during processing to ensure the stability of the workpiece; In the prior art, when a thread rolling machine is rolling threads on a longer workpiece, in order to ensure the stability of the workpiece during thread rolling, a guide mechanism is usually set to transport the workpiece. However, after the workpiece enters the thread rolling machine, it is squeezed by two guide wheels. Longer workpieces are more susceptible to external factors. The instantaneous pressure of the thread rolling machine during extrusion will cause the workpiece to shake, which can easily cause the workpiece to shift, resulting in deviations in the extruded thread, thereby affecting the quality of the workpiece. Summary of the invention

[0004] In view of the problems existing in the prior art, the object of the present invention is to provide a thread rolling machine with automatic loading and unloading.

[0005] To solve the above problem, the present invention adopts the following technical solution, which can stably confine a longer workpiece in the encirclement of the clamping claws and the support ring to avoid the longer workpiece from shaking due to the pressure generated when the rolling machine body starts to squeeze the workpiece.

[0012] Furthermore, a material feeding component is provided at the rear end and the top of the support seat, and the material feeding component includes a loading platform fixedly installed on the back of the left support seat.

[0013] Furthermore, a unloading platform is fixedly installed at the rear end of the support seat on the right side, and cylinders are fixedly installed on the inner lower sides of the loading platform and the unloading platform. The telescopic end of the cylinder on the left side is fixedly connected with a loading rack, and the loading rack is inclined toward the support seat.

[0017] (2) The present invention can restrict the workpiece and ensure smooth rotation of the workpiece by setting a rubber strip that gathers toward the thread rolling machine body. Since multiple rubber strips gather toward the thread rolling machine body, the workpiece will be sufficiently supported. At the same time, the gathered rubber strips will make the workpiece move in only one direction, further avoiding the workpiece from being offset at the beginning of processing.

[0018] (3) The present invention removes impurities on the surface of the workpiece by means of a cleaning brush that rotates with the rotating drum. The rotation of the cleaning brush can effectively improve the cleanliness of the workpiece surface, thereby preventing the rolling machine body from bouncing up due to impurities on the workpiece surface during the extrusion process, thereby affecting the normal processing efficiency of the workpiece, thereby ensuring the smoothness of the workpiece processing.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0022] See also Figures 1 to 10 A thread rolling machine with automatic loading and unloading, comprising a thread rolling machine body 1 and support seats 11 fixedly mounted on the left and right sides of the thread rolling machine body 1, a material guide wheel 12 is distributed in a horizontal linear array on the upper side of the support seat 11, and a material guide component 2 is provided on the upper side of the left support seat 11; The material guiding component 2 includes a fixing sleeve 21 fixedly connected to the upper end of the left supporting seat 11; A positioning assembly 26 is provided at the upper end of the left support seat 11, and the positioning assembly 26 includes a fixed block 261 fixedly connected to the middle part of the upper end of the left support seat 11, and a limiting groove 264 is formed on the surface of the fixed block 261, and a limiting rod 263 is slidably connected inside the limiting groove 264, and a movable plate 262 is fixedly connected to the top of the limiting rod 263, and a tension spring 265 is fixedly connected between the outer side of the limiting rod 263 and the upper side of the inner part of the limiting groove 264, and a sleeve 266 is hinged on the upper side of the movable plate 262, and a moving rod 267 is slidably connected inside the sleeve 266, and a support ring 268 is fixedly connected to the upper side of the moving rod 267, and an embedding groove 2691 is formed on the front and rear sides of the support ring 268, and claws 269 are hinged on the front and rear sides of the support ring 268 through the embedding groove 2691, and the corresponding moving rods 267 on the left and right are hinged on the outer side of the same claw 269.

[0023] There are multiple sleeves 266 , multiple moving rods 267 , and a rotating groove 2692 is formed through the surface of the support ring 268 . There are multiple rotating grooves 2692 , and the moving rods 267 are slidably connected in the rotating grooves 2692 .

[0024] A material pushing assembly 25 is provided at the left end of the left support seat 11 .

[0025] A material feeding component 3 is provided at the rear end and the top of the support seat 11 .

[0026] By adopting the above technical solution, first, during the process of conveying the workpiece to the guide wheel 12 above the support seat 11 through the feeding component 3, the workpiece will be between the two claws 269 and squeeze the two claws 269. After being squeezed, the two claws 269 will rotate in the embedded groove 2691 inside the support ring 268 and be in an open state. After the workpiece enters the support ring 268, it will press the lower half of the two claws 269. Because both claws 269 can be supported by the support ring 268, the two claws 269 will be close together at this time, but the two claws 269 will be pressed together. The claw 269 does not make contact. As the conveying component completes conveying the workpiece, the conveying component will also press the movable plate 262, so that the lower side of the movable plate 262 is tightly fitted with the fixed block 261, so that the limiting rod 263 under the movable plate 262 moves inside the limiting groove 264, and at the same time, the tension spring 265 will be pulled. Because the sleeve 266 hinged on the movable plate 262 is sleeved on the outer side of the movable rod 267 hinged on the claw 269, after the movable plate 262 is pushed downward, the sleeve 266 will also move downward on the outer side of the movable rod 267 until the sleeve 266 can no longer move. When the outer side of the moving rod 267 moves downward, the moving rod 267 and the sleeve 266 are both in a taut state, so that the claw 269 inside the support ring 268 will not be able to rotate. When the workpiece is squeezed and shaken by the rolling machine body 1, the support ring 268 cooperates with the claw 269 to lock the workpiece. When the feeding component 3 starts to lift the workpiece, the movable plate 262 will lose the squeeze. At this time, the tension spring 265 will pull the limit rod 263, so that the movable plate 262 will also be lifted, so that the sleeve 266 and the moving rod 267 are in a relaxed state, and the claw 269 can rotate freely. , and can limit the subsequent workpiece. Since the sleeve 266 and the moving rod 267 are in a relaxed state when the workpiece is loaded, the workpiece can freely enter the support ring 268. After the feeding is completed, the tightened sleeve 266 and the moving rod 267 will also limit the rotation of the claw 269, so that the workpiece is stably restricted in the encirclement of the claw 269 and the support ring 268, so as to avoid the longer workpiece from being shaken by the pressure generated at the moment when the thread rolling machine body 1 starts to squeeze the workpiece, so as to prevent the deviation of the extruded thread due to the offset during the subsequent thread rolling of the workpiece, thereby ensuring the quality of the workpiece.

[0027] like Figure 3 and Figure 4 As shown, a rotating drum 22 is rotatably connected inside the fixed sleeve 21 , and rubber strips 23 are fixedly connected to the right side of the rotating drum 22 in an annular array, and one end of the rubber strips 23 is close to the left side of the thread rolling machine body 1 .

[0028] By adopting the above technical scheme, first, when the workpiece is pushed toward the thread rolling machine by the pushing assembly 25, the workpiece will pass through the fixed sleeve 21. At this time, the workpiece will first enter the inside of the rotating drum 22. As the workpiece passes through the rubber strip 23, the rubber strip 23 gathers toward the direction of the thread rolling machine body 1, and the workpiece moves in the direction of the thread rolling machine body 1, so that when the workpiece passes through the rubber strip 23, multiple rubber strips 23 will be simultaneously stretched outward. If the workpiece is pushed backward when it is just squeezed, multiple rubber strips 23 will squeeze and support the workpiece at the same time, and the workpiece will rotate during the processing. At this time, the rubber strip 23 will also rotate inside the fixed sleeve 21 through the rotating drum 22. Since multiple rubber strips 23 gather toward the direction of the thread rolling machine body 1, the workpiece will be sufficiently supported. At the same time, the gathered rubber strips 23 will make the workpiece move only in one direction, further avoiding the deviation of the workpiece at the beginning of processing.

[0029] like Figure 3 and Figure 4 As shown, a debris removal component 24 is provided inside the fixed sleeve 21, and the debris removal component 24 includes a connecting rod 241 in an annular array fixedly connected to the left side of the rotating drum 22, and the other end of the connecting rod 241 is fixedly connected to a rotating ring 242, and the rotating ring 242 is rotatably connected in the fixed sleeve 21, and a cleaning ring 243 is fixedly installed inside the rotating ring 242.

[0030] By adopting the above technical solution, first, before the workpiece is inserted into the rotating drum 22, the cleaning brush inside the rotating ring 242 will always be in contact with the surface of the workpiece. At the same time, after the sleeve 266 rotates inside the fixed sleeve 21 through the connecting rod 241, the rotation will also drive the cleaning brush to rotate. The rotation of the cleaning brush can effectively improve the cleanliness of the workpiece surface, so as to avoid the rolling machine body 1 from bouncing up due to impurities on the surface of the workpiece during the extrusion process, thereby affecting the normal processing efficiency of the workpiece, thereby ensuring the smoothness of the workpiece processing.

[0031] like Figure 7 As shown, a material pushing assembly 25 is provided at the left end of the left support seat 11 , and the material pushing assembly 25 includes a fixing seat 251 fixedly connected to the left end of the left support seat 11 .

[0032] An electric push rod 252 is fixedly installed on the right side of the vertical part of the fixed seat 251, and a fixed plate 253 is fixedly connected to the upper end of the horizontal part of the fixed seat 251. A pressure sensor 254 is fixedly installed inside the fixed plate 253. A support ring 255 is squeezed and contacted on the upper side of the pressure sensor 254. A push plate 256 is fixedly connected to the telescopic end of the electric push rod 252, and a rotating plate 257 is rotatably connected to the left side of the push plate 256.

[0033] By adopting the above technical solution, first, when the workpiece contacts the guide material, the workpiece will be contacted by the support ring 255. At this time, the support ring 255 will contact the pressure sensor 254 with the help of the pressure of the workpiece and the support ring 255, and then the pressure sensor 254 will transmit the information to the thread rolling machine body 1, and then the electric push rod 252 will be started to push the push plate 256, and the rotating disk 257 pushed by the electric push rod 252 will always be inside the push plate 256, and after the rotating disk 257 contacts the end of the workpiece, the rotating disk 257 will be sleeved on the outside of the workpiece. When the workpiece rotates, the corresponding rotating disk 257 will also rotate inside the push plate 256. Since the pushed workpiece can still keep rotating during the movement, it not only ensures the conveying efficiency of the workpiece, but also improves the stability of the workpiece during rotation, and can again avoid the longer workpiece from being offset at the moment when the thread rolling machine body 1 just starts to squeeze the workpiece.

[0034] like Figure 1 , Figure 2 and Figures 8 to 9 As shown, the feeding component 3 includes a loading platform 31 fixedly installed on the back of the left support seat 11.

[0035] A material unloading platform 34 is fixedly installed at the rear end of the right support seat 11, and a cylinder 32 is fixedly installed on the inner lower side of the loading platform 31 and the unloading platform 34. A loading rack 33 is fixedly connected to the telescopic end of the left cylinder 32, and the loading rack 33 is inclined toward the support seat 11. A material unloading rack 35 is fixedly connected to the telescopic end of the right cylinder 32, and the unloading rack 35 is inclined toward the unloading platform 34. The upper part of the loading rack 33 is in a "Z" shape, and the upper part of the unloading rack 35 is in an "L" shape. Both the loading rack 33 and the unloading rack 35 extend to the top of the support seat 11.

[0036] By adopting the above technical solution, when loading is needed, the cylinder 32 inside the loading platform 31 can be started, and the loading material can be moved upward by the cylinder 32. Because the inclined surface of the loading rack 33 faces below the workpiece, and the inclined surface of the loading platform 31 where the workpiece is placed will face the support seat 11, the loading rack 33 with a "Z" shape on the upper part will lift the workpiece placed horizontally above the loading platform 31, and the workpiece will automatically slide to the right side bend of the loading rack 33, and the right side bends of the loading rack 33 are between two adjacent groups of guide wheels 12, so that when the workpiece slides to the right side bend of the loading rack 33, it will also reach above the guide wheel 12. At the same time, the left side bend of the loading rack 33 will also block the workpiece above the loading platform 31. When the connection point of the left side bend of the loading rack 33 is flush with the bottom of the workpiece, the next The workpiece will roll to the top of the loading rack 33. When unloading, the thread rolling machine body 1 controls the cylinder 32 to lift the unloading rack 35, so that the unloading rack 35 lifts the workpiece from above the guide wheel 12. Because the inclined surface of the unloading platform 34 where the workpiece is placed faces the opposite direction of the support seat 11, and the unloading rack 35 is "L"-shaped, the sliding direction of the workpiece can be specified after the workpiece is lifted. When the lowest point of the unloading rack 35 is higher than the highest point of the unloading platform 34, the workpiece will slide into the area where the workpiece is placed on the unloading platform 34, and the workpiece will gradually roll along the slope. Since the loading rack 33 and the unloading rack 35 are inclined in different directions, the two can complete the loading and unloading operations of the workpiece after moving up and down by the cylinder 32, which reduces the steps of manual operation and achieves the purpose of automatic loading and unloading, thereby improving the processing efficiency of the workpiece.

[0037] like Fig. 9 and Fig.10 As shown, a partition assembly 36 is provided on the upper side and inside of the unloading platform 34 . The partition assembly 36 includes movable grooves 361 opened on the left and right sides of the upper end of the unloading platform 34 . The movable grooves 361 are distributed in a longitudinal linear array.

[0038] A pressing block 362 is slidably connected inside the movable groove 361, and a return spring 363 is fixedly connected between the lower side of the pressing block 362 and the lower side of the inner part of the movable groove 361. Piston cavities 364 are opened on both sides of the left and right sides of the upper end of the unloading platform 34, and the piston cavities 364 are distributed in a longitudinal linear array. The piston cavities 364 are in an "L" shape, and the two adjacent piston cavities 364 on the left and right are connected to the movable groove 361. A baffle 365 is slidably connected inside the piston cavity 364, and the lower half of the baffle 365 is in a "C" shape.

[0039] By adopting the above technical solution, first, after the workpiece is fed to the top of the unloading table 34, the workpiece will roll backward through the slope. During the rolling process of the workpiece, the pressing block 362 in the movable groove 361 will be retracted into the movable groove 361 after being pressed by the workpiece. At this time, the pressing block 362 will squeeze the air in the movable groove 361, and the squeezed air will then enter the piston cavity 364 and lift the baffle 365 in the piston cavity 364. The lifted baffle 365 will be on the workpiece. In front of the workpiece, the above steps are repeated until the workpiece cannot roll, and at this time the baffle 365 at the corresponding position is still lifted up to separate the workpiece. Since the workpiece above the unloading table 34 will lift up the baffle 365 after squeezing the pressing block 362, and the workpiece in the rolling process will frequently press multiple pressing blocks 362, so that the rolling speed of the workpiece is reduced, and the baffle 365 can be isolated from other workpieces after being lifted up, so as to avoid wear or deformation of two adjacent workpieces due to collision, thereby ensuring the quality of the workpiece.

[0040] Working principle: First, when loading is required, the cylinder 32 inside the loading platform 31 can be started, and the loading material can be moved upward by the cylinder 32. Because the inclined surface of the loading rack 33 faces the bottom of the workpiece, the loading rack 33 with a "Z" shape on the upper part lifts the workpiece placed horizontally above the loading platform 31, and the workpiece will automatically slide to the right side bend of the loading rack 33. When the workpiece slides to the right side bend of the loading rack 33, it will also reach the top of the guide wheel 12. At the same time, the left side bend of the loading rack 33 will also block the workpiece above the loading platform 31. When the connection point of the left side bend of the loading rack 33 is flush with the bottom of the workpiece, the next workpiece will roll to the top of the loading rack 33. During the process of conveying the workpiece to the guide wheel 12 above the support seat 11, the workpiece will be between the two The two claws 269 are between the two clamping claws 269, and the two supporting rings 268 are squeezed. After being squeezed, the two clamping claws 269 will rotate through the embedded groove 2691 inside the supporting ring 268 and be in an open state. After the workpiece enters the supporting ring 268, it will press the lower half of the two clamping claws 269. Because the two clamping claws 269 can be supported by the supporting ring 268, the two clamping claws 269 will be close together at this time. At the same time, the loading rack 33 presses the movable plate 262, so that the lower side of the movable plate 262 is tightly fitted with the fixed block 261, so that the limiting rod 263 under the movable plate 262 moves in the limiting groove 264. At the same time, it will also pull the tension spring 265. Because the sleeve 266 hinged to the movable plate 262 is sleeved on the clamping claw 266, the movable plate 262 is The outer side of the movable rod 267 hinged by the claw 269, after the movable plate 262 is pushed downward, the sleeve 266 will also move downward on the outer side of the movable rod 267 until the sleeve 266 can no longer move downward on the outer side of the movable rod 267. At this time, the movable rod 267 and the sleeve 266 are both in a taut state, so that the claw 269 inside the support ring 268 will also be unable to rotate. When the workpiece is squeezed and shaken by the rolling machine body 1 in an instant, the support ring 268 cooperates with the claw 269 to lock the workpiece. When the loading rack 33 starts to lift the workpiece, the movable plate 262 will lose the squeeze. At this time, the tension spring 265 will pull the limit rod 263, so that the movable plate 262 will also be lifted, so that the sleeve 266 and the movable rod 267 are in a relaxed state. At this time, the claw 2 69 can rotate freely and can limit the subsequent workpiece. First, when the workpiece contacts the guide material, the support ring 255 will squeeze the pressure sensor 254. At this time, the pressure sensor 254 transmits the information to the thread rolling machine body 1, and then the electric push rod 252 is started to push the push plate 256. The rotating disk 257 pushed by the electric push rod 252 will always be inside the push plate 256, and after the rotating disk 257 contacts the end of the workpiece, the rotating disk 257 will be sleeved on the outside of the workpiece. When the workpiece rotates, the corresponding rotating disk 257 will also rotate inside the push plate 256. When the workpiece is pushed, before the workpiece is inserted into the rotating drum 22, the cleaning brush inside the rotating ring 242 will clean the surface of the workpiece, and then the workpiece will enter the inside of the rotating drum 22 and pass through the rubber strip 23.Because the rubber strips 23 gather toward the direction of the thread rolling machine body 1, and the workpiece moves in the direction of the thread rolling machine body 1, when the workpiece passes through the rubber strips 23, multiple rubber strips 23 will be simultaneously stretched outward. If the workpiece is pushed backward when it is just squeezed, multiple rubber strips 23 will squeeze and support the workpiece at the same time. During the processing, the workpiece will rotate. At this time, the rubber strips 23 will also rotate inside the fixed sleeve 21 through the rotating cylinder 22. When unloading, the thread rolling machine body 1 controls the cylinder 32 to lift the unloading rack 35, so that the unloading rack 35 lifts the workpiece from above the guide wheel 12. Because the inclined surface of the unloading table 34 where the workpiece is placed faces the opposite direction of the support seat 11, and the unloading rack 35 is in an "L" shape, it can be pointed after the workpiece is lifted. The sliding direction of the workpiece is determined. When the lowest point of the unloading rack 35 is higher than the highest point of the unloading platform 34, the workpiece will slide into the area of ​​the unloading platform 34 where the workpiece is placed, and the workpiece will gradually roll along the slope. During the rolling process of the workpiece, the pressing block 362 in the movable groove 361 will be retracted into the movable groove 361 after being pressed by the workpiece. At this time, the pressing block 362 will squeeze the air in the movable groove 361, and the squeezed air will then enter the piston chamber 364 and lift the baffle 365 in the piston chamber 364. The lifted baffle 365 will be in front of the workpiece. Repeat the above steps until the workpiece cannot roll, and at this time, the baffle 365 at the corresponding position is still lifted to block other workpieces.

[0041] The above is only a preferred specific implementation of the present invention; however, the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
