Description

Technical Field

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

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

[0003] The existing rivet processing method is usually to cut out a solid cylindrical column through a lathe, and then combine and fix the rivet core and the rivet body through cold heading and other working forms. However, in the process of automatic cutting, there will be uneven force on the cutting point, which may cause different deformation effects at the cutting point. In order to ensure the smooth combination and assembly production of the rivets and the subsequent normal work, it is usually necessary to straighten the cut raw materials. The existing processing method often re-selects and straightens a large number of rivets after cutting, which wastes a lot of working time and seriously affects the overall work efficiency. In addition, due to different force conditions, the deformation effects produced are also different. Usually, raw materials with relatively small deformation can be straightened conveniently and quickly, which meets the working effect of rapid production. However, raw materials with large deformation are not convenient to straighten and are usually not selected as raw materials for production. However, the existing work cannot automatically screen them, and a lot of time needs to be wasted on picking in the later stage, which also seriously affects the work efficiency.

DETAILED DESCRIPTION

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

[0042] In the description of the present invention, it is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are 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 cannot be understood as a limitation on the present invention.

[0043] Reference Figure 1-Figure 15, a special long stainless steel solid rivet processing equipment, including a workbench 1, one side of the upper surface of the workbench 1 is fixedly connected to a conveying frame 2, the upper surface of the workbench 1 and the side of the conveying frame 2 is fixedly connected to a cutter 3, the upper surface of the workbench 1 is fixedly connected to a connection box 4, one side of the connection box 4 is connected to a processing box 5, the connection box 4 is located on one side of the conveying frame 2, and also includes a screening mechanism 6, the screening mechanism 6 is used to perform curvature detection and screening on the cut cylindrical raw materials, the screening mechanism 6 is slidably connected to one side of the inside of 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 to the inside of 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 frame 2, the interior of the positioning ring 602 is rotatably connected to a gear column 12, the bottom of the positioning ring 602 is slidably connected to a gear plate 13, the top of the gear plate 13 is meshed with one side of the gear column 12, the bottom of the gear column 12 is meshed with a rack 14, the other end of the rack 14 passes through the outside of the positioning ring 602 and is slidably connected to the inside of the screening plate 601, the transmission belt 603 is rotatably connected to the inside of the connection box 4 by electric drive, and the gear plate 13 can mesh with the top of the transmission belt 603 when it slides to the bottom of the positioning ring 602, the interior of the screening plate 601 is evenly and fixedly connected with four hydraulic columns 15, and the four hydraulic columns 15 are distributed in a circular manner, and the output end of the hydraulic column 15 is rotatably connected to an extrusion wheel 16.

[0044] The raw material to be cut is transported to the inside of the connection box 4 by the conveying frame 2, and the cutting point is fixed, and then the raw material is cut by the cutter 3. Since one end of the raw material has entered the inside of the conveying mechanism 7 at this time, it is transported to the inside of the processing tank 28 by the conveying mechanism 7 after cutting. At this time, if the curvature of the cutting point is too large, the raw material will hook the screening plate 601 and force the screening plate 601 to slide in 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 tooth plate 13 to slide down and mesh with the top of the transmission belt 603. At this time, the positioning ring 602 will follow the transmission belt 603 to slide toward the other side of the connection box 4;

[0045] When the curvature of the cutting part is relatively small, the cut raw material will not contact the screening plate 601 but will be directly transported to the processing box 5 via the conveying mechanism 7. When the cut raw material passes through the screening plate 601, four hydraulic columns 15 push the four extrusion wheels 16 respectively, forcing the extrusion wheels 16 to maintain the corresponding pressure, which can have a preliminary straightening effect on the cut raw material and speed up the overall work 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 connecting box 4. 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 connecting 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 connected to the inside of the conveying box 701 in a symmetrical rotation up and down. Two linkage wheels 18 are symmetrically fixedly connected on both sides of the surface of the conveying wheel 702. A tensioning wheel 19 is slidably connected to the inside of the conveying box 701. The tensioning wheel 19 and the linkage wheel 18 are connected by belt transmission. A tensioning spring 20 is fixedly connected to the surface of the tensioning wheel 19, and the other end of the tensioning spring 20 is fixed. 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 the transmission column 21 through a coupling, and the surface of the linkage wheel 18 on the lower side is fixedly connected to the gear sleeve 22, and the end of the transmission column 21 away from the motor 703 is plugged and meshed with the gear sleeve 22, and one side of the surface of the gear sleeve 22 is meshed with a steering tooth 23, and one side of the steering tooth 23 is fixedly connected to a guide wheel 24, and one side of the guide wheel 24 is connected to a rotating wheel 25 through a belt drive, and the rotating wheel 25 is rotatably connected to the gear sleeve 22, and the middle part of the rotating wheel 25 is penetrated by the transmission column 21, and when the connecting column is separated from the gear sleeve 22, it can mesh with the middle part of the rotating wheel 25, and the surface of the motor 703 is fixedly connected to a positioning strip 26, and a positioning groove 27 is provided inside the connecting box 4, and the positioning strip 26 is slidably connected to the positioning groove 27.

[0047] The motor 703 drives the transmission column 21 to rotate. At this time, the transmission column 21 is plugged and meshed with the inner part of the gear sleeve 22. At this time, the gear sleeve 22 drives the conveying wheel 702 below 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 following the transmission belt 603, the conveying box 701 slides following the positioning ring 602. At this time, the positioning bar 26 slides along the positioning groove 27, and when the positioning bar 26 slides from one end of the positioning groove 27 to the other end, the positioning bar 26 will be blocked by the positioning groove 27. At this time, the conveying The sliding state of the delivery box 701 has not stopped, that is, at this time, the positioning bar 26 will drive the motor 703 to be in a static state without sliding, while the delivery box 701 and the gear sleeve 22 and other structures continue to slide. At this time, the transmission column 21 will separate from the gear sleeve 22 and gradually connect with the inside of the guide wheel 24. The transmission column 21 can drive the guide wheel 24 to rotate in the same direction by driving the rotating wheel 25 to rotate. At this time, the steering tooth 23 will drive the gear sleeve 22 to reverse, thereby forcing the raw materials entering between the two delivery wheels 702 to be pushed toward the outside of the connecting box 4, thereby completing the removal of raw materials with excessive curvature.

[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] The friction mechanism 9 is slidably connected to the inside of the processing box 5. The friction mechanism 9 is used to grind the cut 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 the two ends of the processing tank 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 to the grinding plate 902. The connecting plate 901 and the grinding plate 902 are both 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 strip 31. The connecting strip 31 is slidably connected to the inside of the processing box 5. The 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. The driving and rotating mechanism 10 rotates, and the transmission mechanism 11 includes a connecting rod 111, a gear rod 112 and a guide rod 113. The connecting rod 111, the gear rod 112 and the guide rod 113 are all slidably connected to the inside of the processing box 5. The tops of the two connecting strips 31 are meshed with rotating teeth 35. The connecting rod 111 and the gear rod 112 can be meshed with the two rotating teeth 35 respectively, and the length of the connecting rod 111 is less than the length of the gear rod 112. One side of the surface of the connecting ring 34 is meshed with a gear 36, and one side of the gear 36 is meshed with a connecting tooth 37. The inside of the connecting tooth 37 is rotatably connected with a ratchet 38, and one side of the ratchet 38 is fixedly connected with a transmission tooth 39, which can be meshed 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] In the process of the connection frame 802 descending, the connection rod 111 and the gear rod 112 can be driven to descend together. In the process of the connection rod 111 and the gear rod 112 respectively engaging with the two rotating teeth 35, the two connection plates 901 are driven to slide close to each other through the connection strip 31, thereby forcing the two grinding plates 902 to approach the cuts at both ends of the raw material, and the cuts at both ends can be grinded in conjunction with the rotation effect of the raw material itself. In the process of the connection frame 802 descending, the guide rod 113 is driven to engage with the transmission tooth 39, There is a one-way meshing connection effect between the ratchet teeth 38 and the connecting teeth 37. At this time, the synchronous rotation of the transmission teeth 39 and the ratchet teeth 38 will not drive the connecting teeth 37 to rotate. When the straightening work is completed, the connecting frame 802 moves up. At this time, the guide rod 113 drives the connecting teeth 37 to rotate in the opposite direction, and at this time, the ratchet teeth 38 can smoothly drive the connecting teeth 37 to rotate, thereby driving the gear 36 to rotate through the connecting teeth 37, and driving the connecting ring 34 to rotate through the meshing effect between the gear 36 and the connecting ring 34, thereby forcing the entire rotating mechanism 10 to rotate.

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

[0053] Among them, the spring 40 drives the two clamping blocks 41 to approach each other, so as to limit and fix the raw materials entering the positioning ring 602 to prevent them from falling, thereby ensuring the normal progress of the conveying work, and the reset spring 43 can ensure that after the raw materials with excessive curvature are pushed out, the tooth plate 13 is separated from the transmission belt 603. At this time, the reset spring 43 recovers to the normal state through the stretched state, thereby driving the positioning ring 602 and the conveying box 701 and other structures to reset, which can facilitate work.

[0054] The specific working principle and use method of the present invention are explained in detail below: When in use, the first step is to transport the raw material to be cut toward the inside of the connection box 4 through the conveying frame 2, and fix the cutting point, and then cut the raw material through the cutter 3. Since one end of the raw material has entered the inside of the conveying mechanism 7 at this time, after the cutting is completed, the conveying mechanism 7 is transported to the inside of the processing tank 28. At this time, if the curvature of the cutting point is too large, the raw material will hook the screening plate 601 and force the screening plate 601 to slide in the direction close to the positioning ring 602. At this time, the rack 14 will drive the tooth column 1 2 rotates, thereby forcing the tooth plate 13 to slide down and mesh with the top of the transmission belt 603. At this time, the positioning ring 602 will follow the transmission belt 603 to slide toward the other side of the connection box 4. When the curvature of the cutting part is relatively small, the cut raw materials will not contact the screening plate 601 and will be directly transported to the processing box 5 via the conveying mechanism 7. When the cut raw materials pass through the screening plate 601, the four extrusion wheels 16 are pushed by the four hydraulic columns 15 respectively, forcing the extrusion wheels 16 to maintain the corresponding pressure, which can achieve the effect of preliminary straightening of the cut raw materials and improve the overall work efficiency;

[0055] In the second step, the transmission column 21 is driven to rotate by the motor 703. At this time, the transmission column 21 is plugged and meshed with the inner part of the gear sleeve 22. At this time, the gear sleeve 22 will drive the conveying wheel 702 below 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 with the transmission belt 603, the conveying box 701 slides with the positioning ring 602. At this time, the positioning bar 26 slides along the positioning groove 27, and when the positioning bar 26 slides from one end of the positioning groove 27 to the other end, the positioning bar 26 will be blocked by the positioning groove 27. At this time, the conveying The sliding state of the delivery box 701 does not stop, that is, at this time, the positioning bar 26 will drive the motor 703 to be in a static state without sliding, while the delivery box 701 and the gear sleeve 22 and other structures continue to slide. At this time, the transmission column 21 will separate from the gear sleeve 22 and gradually plug into the inside of the guide wheel 24. The transmission column 21 can drive the guide wheel 24 to rotate in the same direction by driving the rotating wheel 25 to rotate. At this time, the steering tooth 23 will drive the gear sleeve 22 to reverse, thereby forcing the raw materials entering between the two delivery wheels 702 to be pushed toward the outside of the connecting box 4, so as to complete the removal of the raw materials with excessive curvature;

[0056] In the third step, 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.
