Description

Technical Field

[0001] The present invention relates to the technical field of straightening devices, and particularly relates to a processing device for extra-long stainless steel solid rivets. Background Technique

[0002] A rivet is a nail-shaped object used to connect two parts (or components) with through holes and a cap at one end. It uses its own deformation or interference fit to connect the riveted parts. In order to ensure the connection strength and integrity, a long solid rivet is usually used to rivet and fix two structural parts. Such long solid rivets usually encounter some problems during the processing.

[0003] The existing rivet processing method usually cuts out a cylindrical solid column through a lathe device, and then combines and fixes the rivet core and the rivet body through working forms such as cold heading. However, during the automatic cutting process, the cutting points may have uneven stress, which may cause different deformation effects at the cutting points. In order to ensure the smooth assembly production of the rivets and the subsequent normal operation, the cut raw materials usually need to be straightened. The existing processing method often picks and straightens a large number of rivets after cutting, which will waste a lot of working hours and seriously affect the overall work efficiency. And due to different stress conditions, the deformation effects are also different. Usually, the raw materials with relatively small deformation can be straightened conveniently and quickly, meeting the working effect of rapid production. However, the principle with large deformation is not convenient to straighten and is usually not selected for raw material production. But the existing work cannot automatically screen it, and a large amount of time needs to be wasted for picking later, which will also seriously affect the work efficiency. Summary of the Invention

[0024] In summary, the present invention positions and fixes through a screening plate and a positioning ring cylindrical nail core, and cooperates with a conveying mechanism to convey the cut raw materials, and detects the raw materials with different bending degrees at the cutting points. The steering gear drives the gear sleeve to rotate in the reverse direction, so as to remove the raw materials with too large bending degree. The raw materials can be pre-straightened by the pressing wheel, and then the raw materials are straightened again through the rotation effect between the straightening roller and the bottom roller. The rotation of the friction belt drives the raw materials to rotate self, ensuring a comprehensive straightening effect. The transmission mechanism drives the two friction plates to approach the cut ends of the raw materials to complete grinding, preventing the cut ends of the raw materials from being too sharp or having sharp burrs that may cause harm to workers, and ensuring the reliability of rivet production.

Detailed implementation manners

[0041] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0042] In the description of the present invention, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0043] Refer to Figures 1 - 15, a processing device for extra-long stainless steel solid rivets, comprising a workbench 1. On one side of the upper surface of the workbench 1, a conveying rack 2 is fixedly connected. On the upper surface of the workbench 1 and on one side of the conveying rack 2, a cutter 3 is fixedly connected. On the upper surface of the workbench 1, a connection box 4 is fixedly connected. On one side of the connection box 4, a processing box 5 is communicated. The connection box 4 is located on one side of the conveying rack 2. It further includes a screening mechanism 6, which is used for detecting and screening the curvature of the cylindrical raw materials after cutting. The screening mechanism 6 is slidably connected to one side inside the connection box 4. The screening mechanism 6 includes a screening plate 601, a positioning ring 602 and a transmission belt 603. The positioning ring 602 is slidably connected inside the connection box 4. The screening plate 601 is slidably connected to one side of the positioning ring 602, and the screening plate 601 is located between the connection box 4 and the conveying rack 2. Inside the positioning ring 602, a toothed column 12 is rotatably connected. At the bottom of the positioning ring 602, a toothed plate 13 is slidably connected. The top of the toothed plate 13 meshes with one side of the toothed column 12. At the bottom of the toothed column 12, a rack 14 meshes. The other end of the rack 14 penetrates outside the positioning ring 602 and is slidably connected to the inside of the screening plate 601. The transmission belt 603 is rotationally connected inside the connection box 4 by electric drive, and when the toothed plate 13 slides below the positioning ring 602, it can mesh with the top of the transmission belt 603. Inside the screening plate 601, four hydraulic cylinders 15 are evenly and fixedly connected, and the four hydraulic cylinders 15 are distributed in a circular pattern. The output end of the hydraulic cylinder 15 is rotatably connected with a pressing wheel 16.

[0044] Among them, the raw materials to be cut are conveyed into the inside of the connection box 4 through the conveying rack 2, and the cutting point is fixed. Then, the raw materials are cut by the cutter 3. Since one end of the raw materials has entered the inside of the conveying mechanism 7 at this time, after cutting, they are conveyed into the inside of the processing tank 28 by the conveying mechanism 7. At this time, if the curvature of the cutting point is too large, the raw materials will hook the screening plate 601 and force the screening plate 601 to slide towards the direction close to the positioning ring 602. At this time, the rack 14 will drive the toothed column 12 to rotate, thereby forcing the toothed plate 13 to slide down and mesh with the top of the transmission belt 603. At this time, the positioning ring 602 will slide towards the other side of the connection box 4 along with the transmission belt 603;

[0045] When the curvature at the cutting part is relatively small, the cut raw materials will not contact the screening plate 601 and are directly conveyed into the processing box 5 by the conveying mechanism 7. When the cut raw materials pass through the screening plate 601, the four hydraulic cylinders 15 respectively push the four pressing wheels 16, forcing the pressing wheels 16 to maintain corresponding pressures, which can play a preliminary straightening effect on the cut raw materials and can improve the overall working efficiency.

[0046] The conveying mechanism 7 is used to convey the cylindrical raw materials screened by the screening mechanism 6. The conveying mechanism 7 is slidably connected to the inside of the connection box 4, and the conveying mechanism 7 is fixedly connected to the screening mechanism 6. The conveying mechanism 7 includes a conveying box 701, two conveying wheels 702 and a motor 703. The conveying box 701 is slidably connected to the inside of the connection box 4, and a connecting block 17 is fixedly connected between the conveying box 701 and the positioning ring 602. The two conveying wheels 702 are rotatably connected to the inside of the conveying box 701 in an up-and-down symmetrical manner. On both sides of the surface of the conveying wheel 702, two linkage wheels 18 are symmetrically and fixedly connected. A tension wheel 19 is slidably connected to the inside of the conveying box 701. The tension wheel 19 is connected by a belt to the linkage wheel 18. A tension spring 20 is fixedly connected to the surface of the tension wheel 19, and the other end of the tension spring 20 is fixedly connected to the inside of the conveying box 701. The motor 703 is slidably connected to the surface of the conveying box 701. The output end of the motor 703 is fixedly connected to a transmission column 21 through a coupling. A gear sleeve 22 is fixedly connected to the surface of the linkage wheel 18 on the lower side. The end of the transmission column 21 away from the motor 703 is inserted and engaged with the gear sleeve 22. A steering gear 23 is engaged with one side of the surface of the gear sleeve 22. A guide wheel 24 is fixedly connected to one side of the steering gear 23. A belt drives a runner 25 on one side of the guide wheel 24. The runner 25 is rotatably connected to the gear sleeve 22. The middle of the runner 25 is penetrated by the transmission column 21, and when the connecting column is separated from the gear sleeve 22, it can be engaged with the middle of the runner 25. A positioning strip 26 is fixedly connected to the surface of the motor 703. A positioning groove 27 is opened in the inside of the connection box 4. The positioning strip 26 is slidably connected to the positioning groove 27.

[0047] Among them, the motor 703 drives the transmission column 21 to rotate. At this time, the transmission column 21 is inserted and engaged with the inside of the gear sleeve 22. At this time, the gear sleeve 22 drives the lower conveying wheel 702 to rotate. When the raw materials pass between the two conveying wheels 702, the raw materials can be stably conveyed. When the positioning ring 602 slides along with the conveyor belt 603, the conveying box 701 will slide along with the positioning ring 602. At this time, the positioning strip 26 will slide along the positioning groove 27. And when the positioning strip 26 slides from one end of the positioning groove 27 to the other end, the positioning strip 26 will be blocked by the positioning groove 27. At this time, the sliding state of the conveying box 701 does not stop, that is, at this time, the positioning strip 26 drives the motor 703 to be in a stationary state without sliding, while the structures such as the conveying box 701 and the gear sleeve 22 continue to slide. At this time, the transmission column 21 will be separated from the gear sleeve 22 and gradually inserted into the inside of the guide wheel 24. By driving the runner 25 to rotate, the transmission column 21 can drive the guide wheel 24 to rotate in the same direction. At this time, the steering gear 23 drives the gear sleeve 22 to form a reverse rotation, so as to force the raw materials entering between the two conveying wheels 702 to be pushed out of the connection box 4, so as to complete the rejection of the raw materials with too large bending degree.

[0048] A straightening mechanism 8 is provided inside the processing box 5. The straightening mechanism 8 is used to straighten the raw materials transported to the processing box 5 via the conveying mechanism 7 again. The straightening mechanism 8 includes a plurality of bottom rollers 801, a connecting frame 802 and a straightening roller 803. A processing tank 28 is provided inside the processing box 5. A plurality of bottom rollers 801 are evenly rotated and connected to the inside of the processing tank 28. The connecting frame 802 is slidably connected to the inside of the processing tank 28 through a hydraulic cylinder. The straightening roller 803 is slidably connected to the bottom of the connecting frame 802 through a connecting shaft and other components through electric drive, and the straightening roller 803 can be rotatably connected to the connecting frame 802. One end of the processing tank 28 is connected to the connecting box 4, and a discharge port 29 is provided on one side of the processing box 5. The other end of the discharge port 29 is arranged through the processing tank 28. A rotating mechanism 10 is used to drive the raw materials to rotate in the processing box 5, and can push and discharge the raw materials after straightening treatment. The rotating mechanism 10 is rotatably connected to the processing box 5. Inside the sorting box 5, the rotating mechanism 10 includes a base plate 101, a connecting wheel 102 and two transmission wheels 103. The base plate 101 is slidably connected to the inside of the processing tank 28, and the base plate 101 is located below the bottom roller 801. The surface of the connecting wheel 102 is transmission-connected to the two transmission wheels 103 through two belts respectively. A friction belt 32 is rotationally connected between the two transmission wheels 103, and the two transmission wheels 103 and the friction belt 32 are both located between two of the bottom rollers 801. One side of the connecting wheel 102 is fixedly connected to a driver 33, and the driver 33 is fixedly connected to the top of the base plate 101. The bottom of the base plate 101 is fixedly connected to a connecting ring 34, and the connecting ring 34 is slidably connected to the inside of the processing box 5. One side of the two transmission wheels 103 are rotationally connected to a reinforcement rod 42, and the other end of the reinforcement rod 42 is fixedly connected to the surface of the base plate 101, and one end of one of the reinforcement rods 42 close to the transmission wheel 103 can be rotationally connected to the processing tank 28.

[0049] Among them, when the raw material enters the processing tank 28, it will lie flat on the surface of several bottom rollers 801. At this time, the effect of the hydraulic push of the connecting frame 802 decreases, forcing the straightening roller 803 to approach the raw material, and the straightening roller 803 is forced to slide back and forth quickly along the connecting frame 802 by electric drive. At the same time, the connecting wheel 102 is driven to rotate by the driver 33, and the friction belt 32 can be driven to rotate by the two transmission wheels 103. The friction effect between the friction belt 32 and the cylindrical raw material forces the raw material to rotate, which can ensure the all-round straightening effect of the straightening roller 803 and the bottom roller 801 on the raw material. After the straightening work is completed, one end of one of the fixed rods close to the transmission wheel 103 can rotate between the processing tank 28, forcing the bottom plate 101 and the entire rotating mechanism 10 to rotate around this point, so as to push the processed raw material out of the processing tank 28 and complete the discharge work through the discharge port 29.

[0050] Friction mechanism 9 is slidably connected to the inside of the processing box 5. The friction mechanism 9 is used for grinding the cutting openings at both ends of the raw material. The friction mechanism 9 includes two connecting plates 901 and two grinding plates 902. The two connecting plates 901 are respectively slidably connected to both ends of the processing groove 28. One side of the surface of the connecting plate 901 is fixedly connected with a top spring 30. The other end of the top spring 30 is fixedly connected with the grinding plate 902. And both the connecting plate 901 and the grinding plate 902 are located between the bottom roller 801 and the straightening roller 803. One side of the surface of the connecting plate 901 is fixedly connected with a connecting bar 31. The connecting bar 31 is slidably connected to the inside of the processing box 5. Transmission mechanism 11 is slidably connected to the inside of the processing box 5. The transmission mechanism 11 is used to drive the friction mechanism 9 to slide and the rotating mechanism 10 to rotate. The transmission mechanism 11 includes a connecting rod 111, a toothed rod 112 and a guide rod 113. The connecting rod 111, the toothed rod 112 and the guide rod 113 are all slidably connected to the inside of the processing box 5. The tops of both connecting bars 31 are engaged with rotating teeth 35. The connecting rod 111 and the toothed rod 112 can be respectively engaged with the two rotating teeth 35. And the length of the connecting rod 111 is less than the length of the toothed rod 112. One side of the surface of the connecting ring 34 is engaged with a gear 36. One side of the gear 36 is engaged with a connecting tooth 37. The inside of the connecting tooth 37 is rotatably connected with a ratchet tooth 38. One side of the ratchet tooth 38 is fixedly connected with a transmission tooth 39. The transmission tooth 39 can be engaged with the guide rod 113. The gear 36, the connecting tooth 37 and the transmission tooth 39 are all rotatably connected to the inside of the processing box 5.

[0051] Among them, during the process of the connecting frame 802 descending, it can drive the connecting rod 111 and the toothed rod 112 to descend together. During the process of the connecting rod 111 and the toothed rod 112 being respectively engaged with the two rotating teeth 35, it will drive the two connecting plates 901 to produce a sliding effect of approaching each other through the connecting bar 31, so as to force the two grinding plates 902 to approach the cut openings at both ends of the raw material, and can cooperate with the rotating effect of the raw material itself to grind the cut openings at both ends. And during the process of the connecting frame 802 descending, it will drive the guide rod 113 to be engaged with the transmission tooth 39. Since the connection effect between the ratchet tooth 38 and the connecting tooth 37 is a one-way engagement, at this time, the synchronous rotation of the transmission tooth 39 and the ratchet tooth 38 will not drive the connecting tooth 37 to rotate. When the straightening work is over, the connecting frame 802 moves upward. At this time, the guide rod 113 drives the connecting tooth 37 to rotate in the reverse direction. And at this time, the ratchet tooth 38 can smoothly drive the connecting tooth 37 to rotate, so as to drive the gear 36 to rotate through the connecting tooth 37, and drive the connecting ring 34 to rotate through the meshing effect between the gear 36 and the connecting ring 34, so as to force the entire rotating mechanism 10 to rotate.

[0052] Inside the positioning ring 602, two springs 40 are symmetrically and fixedly connected. The other ends of the springs 40 are fixedly connected with clamping blocks 41. The two clamping blocks 41 are symmetrically and slidably connected inside the positioning ring 602. The bottom of the connecting block 17 is slidably connected inside the connecting box 4. One side of the connecting block 17 is fixedly connected with a return spring 43, and the other end of the return spring 43 is fixedly connected inside the connecting box 4.

[0053] Among them, by driving the two clamping blocks 41 to approach each other through the springs 40, the raw materials entering the positioning ring 602 can be limited and fixed to prevent falling, ensuring the normal progress of the conveying work. And through the return spring 43, it can ensure that after the raw materials with too large bending degree are pushed out, the toothed plate 13 is separated from the transmission belt 603. At this time, the return spring 43 returns from the stretched state to the normal state, thereby driving the reset of structures such as the positioning ring 602 and the conveying box 701, which is convenient for work.

[0054] The following makes a detailed explanation of the specific working principle and usage method of the present invention: When in use, in the first step, the raw materials to be cut are conveyed into the connecting box 4 through the conveying frame 2, and the cutting point is fixed. Then, the raw materials are cut by the cutter 3. Since one end of the raw materials has entered the inside of the conveying mechanism 7 at this time, after cutting, they are conveyed into the inside of the treatment tank 28 by the conveying mechanism 7. At this time, if the bending degree of the cutting point is too large, the raw materials will hook the screening plate 601 and force the screening plate 601 to slide towards the direction close to the positioning ring 602. At this time, the rack 14 will drive the tooth column 12 to rotate, thereby forcing the toothed plate 13 to slide down and mesh with the top of the transmission belt 603. At this time, the positioning ring 602 will slide towards the other side of the connecting box 4 along with the transmission belt 603. When the bending degree at the cutting part is relatively small, the cut raw materials will not contact the screening plate 601 and are directly conveyed into the treatment box 5 by the conveying mechanism 7. When the cut raw materials pass through the screening plate 601, the four hydraulic cylinders 15 respectively push the four pressing wheels 16 to force the pressing wheels 16 to maintain the corresponding pressure, which can initially straighten the cut raw materials and improve the overall working efficiency.

[0055] Step 2: Drive the transmission column 21 by the motor 703. At this time, the transmission column 21 is inserted and engaged with the inside of the gear sleeve 22. At this time, the gear sleeve 22 will drive the lower conveying wheel 702 to rotate. When the raw material passes between the two conveying wheels 702, the raw material can be stably conveyed. When the positioning ring 602 slides along with the conveyor belt 603, the conveying box 701 will slide along with the positioning ring 602. At this time, the positioning strip 26 will slide along the positioning groove 27. And when the positioning strip 26 slides from one end of the positioning groove 27 to the other end, the positioning strip 26 will be blocked by the positioning groove 27. At this time, the sliding state of the conveying box 701 does not stop, that is, at this time, the positioning strip 26 will drive the motor 703 to be in a stationary state where it no longer slides, while the structures such as the conveying box 701 and the gear sleeve 22 continue to slide. At this time, the transmission column 21 will separate from the gear sleeve 22 and gradually be inserted into the inside of the guide wheel 24. By driving the runner 25 to rotate, the transmission column 21 can drive the guide wheel 24 to rotate in the same direction. At this time, the steering gear 23 will drive the gear sleeve 22 to reverse, so as to force the raw material entering between the two conveying wheels 702 to be pushed out of the outside of the connection box 4, thereby completing the rejection of the raw material with too large a bending degree.

[0056] Step 3: When the raw material enters the processing tank 28, it will lie flat on the surfaces of a number of bottom rollers 801. At this time, the connecting frame 802 descends due to the hydraulic push, forcing the straightening roller 803 to approach the raw material. By means of electric drive, the straightening roller 803 is forced to slide rapidly back and forth along the connecting frame 802. At the same time, by driving the connecting wheel 102 to rotate through the driver 33, the friction belt 32 can be driven to rotate through the two transmission wheels 103. Through the friction effect between the friction belt 32 and the cylindrical raw material, the raw material is forced to rotate, which can ensure the all-round straightening effect of the straightening roller 803 and the bottom roller 801 on the raw material. And after the straightening work is completed, through the effect that one end of the fixing rod close to the transmission wheel 103 can rotate with the processing tank 28, the bottom plate 101 and the entire rotating mechanism 10 are forced to rotate around this point, so as to push the processed raw material out of the processing tank 28 and complete the discharging work through the discharging port 29.
