Description

Technical Field

[0001] The present invention relates to the technical field of rigging processing equipment, and particularly to an automatic rigging combination processing device. Background Art

[0002] A rigging is a tool used in conjunction with ropes and cables and is widely used in various lifting, fixing, and transportation operations. Rigging is mainly divided into two categories: metal rigging and synthetic fiber rigging. Metal rigging includes wire rope slings, chain slings, shackles, hooks, etc., while synthetic fiber rigging is mainly made of materials such as nylon, polypropylene, and polyester. Some rigging accessories, such as wire rope sheaths and shackles, are processed from metal sheets. When processing metal sheets into rigging accessories, a circular shear device is required to cut the metal sheets so that the width dimensions of the metal sheets can be consistent.

[0003] When the circular shear device in the prior art cuts a metal sheet, after the circular blade cuts the edge of the metal sheet, the waste edge of the metal sheet may produce a "tear strip (i.e., a thin part where the finished material and the waste edge are not completely cut and adhered together)" with the finished material, thereby causing the waste edge to not be completely separated from the finished material, thus affecting the winding of the finished material. Summary of the Invention

[0004] The purpose of the present invention is to provide an automatic rigging combination processing device to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

[0006] An automatic rigging combination processing device, comprising:

[0007] A machine base and a spindle base installed on the machine base. Two spindles are rotatably connected in the spindle base from top to bottom in sequence;

[0008] A connecting shaft coaxially connected to the end of the spindle. A circular blade is fixedly sleeved on the periphery of the connecting shaft;

[0009] A fixing plate connected to the surface of the spindle base. The outer wall of the fixing plate is connected with a support with a U-shaped outer contour;

[0010] A swing block rotatably connected to the support. A bite inlet is provided on the side of the swing block away from the fixing plate. The swing block is arranged corresponding to the two circular blades;

[0011] A reciprocating swing unit arranged on the outer wall of the fixing plate. The reciprocating swing unit is used to drive the swing block to swing up and down reciprocally.

[0012] Further, the main shaft seat includes a seat body connected to the top of the machine base. The two sides of the seat body are open and are respectively connected with a cover plate and a connecting seat. The fixed plate is connected to the outer wall of the connecting seat. Two main shaft mounting seats are installed in the connecting seat, and the two main shafts are respectively installed in the two main shaft mounting seats. A rotating unit for driving the two main shafts to rotate is arranged in the seat body.

[0013] Further, the rotating unit includes a driving motor installed on the cover plate. A driving gear is installed on the motor shaft of the driving motor. Two transmission shafts are rotatably connected to the inner cavity of the seat body. Transmission gears are fixedly sleeved on the peripheries of the transmission shafts. The two transmission gears are externally meshed, and one of the transmission gears is externally meshed with the driving gear. The main shaft and the transmission shaft are correspondingly connected through a universal coupling.

[0014] Further, upper pressing wheels and lower pressing wheels are respectively sleeved on the ends of the two connecting shafts far away from the fixed plate. A material biting opening is formed between the upper pressing wheel and the lower pressing wheel. The end faces of the upper pressing wheel and the lower pressing wheel are respectively abutted against the two disc cutters correspondingly. Two locking nuts are sleeved on the periphery of the connecting shaft in a threaded manner. The locking nuts are used for fixing the disc cutters on the periphery of the connecting shaft.

[0015] Further, retaining rings are coaxially fixed to the ends of the upper pressing wheel and the lower pressing wheel far away from the fixed plate.

[0016] Further, the reciprocating swing unit includes a swing sleeve arranged in the middle defective part of the support. Support pivots are fixedly connected to both sides of the periphery of the swing sleeve. The support pivots are rotatably connected to both sides of the support. A mounting shaft is rotatably connected coaxially in the swing sleeve. A swing block is fixedly connected to the end of the mounting shaft far away from the fixed plate. A driving structure for driving the swing sleeve to rotate around the axis of the support pivot is arranged on the outer wall of the fixed plate.

[0017] Further, the driving structure includes a fixed hinge seat connected to the outer wall of the fixed plate. A connecting block is rotatably connected to the outer wall of the fixed hinge seat. One end of the connecting block is connected with a driving element. A movable block is fixedly connected to the output end of the driving element. The movable block is hinged to the periphery of the swing sleeve.

[0018] Further, a small gear is fixedly sleeved on the end of the mounting shaft far away from the swing block. An arc-shaped rack is fixedly connected to the inner wall of one side of the support. The center of the arc of the arc-shaped rack is coaxial with the support pivot. The small gear is externally meshed with the arc-shaped rack.

[0019] Further, a pressing slide rod is coaxially and slidably inserted into the mounting shaft. One end of the pressing slide rod penetrates to the biting inlet, and the other end is rotatably fitted with a ball. A special-shaped block is fixedly connected to the surface of the support. A rolling groove in the form of a notch is formed on one side surface of the special-shaped block facing the swing sleeve. An elastic pressing structure is arranged on the periphery of the pressing slide rod, and the elastic pressing structure is used to drive the pressing slide rod to move towards the special-shaped block so that the ball rolls into contact with the rolling groove.

[0020] Further, the elastic pressing structure includes a stop screw sleeve sleeved on the periphery of the pressing slide rod in a threaded manner, and an elastic member is arranged between the end face of the stop screw sleeve and the end face of the mounting shaft.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. In the present invention, when the metal sheet is sheared by the disc cutter, the waste edge sheared off passes through the biting inlet of the swing block, and then the swing block is driven by the reciprocating swing unit to swing up and down reciprocally. Further, the inner wall of the biting inlet of the swing block generates a pressing force on the waste edge, so that the waste edge swings up and down along the tearing belt position of the finished metal sheet material. Further, by reciprocally bending the waste edge, the waste edge can be separated from the finished metal sheet material.

[0023] 2. In the present invention, when the swing block swings up and down to reciprocally bend the waste edge, the small gear meshes with the arc rack for transmission. Further, when driving the swing block to swing up and down, a circumferential rotational movement around the mounting shaft can be generated. Further, a twisting deformation acting force is generated on the waste edge by the biting inlet of the swing block, so that the waste edge can be more smoothly separated from the finished metal sheet material, thereby further reducing the generation of the tearing belt during the shearing of the metal sheet. In addition, by twisting and deforming the waste edge, the whole waste edge is not likely to generate a large bend.

[0024] 3. In the present invention, when the swing block swings up and down, the ball will roll on the inner wall of the notch groove of the special-shaped block. Further, the pressing slide rod can reciprocally penetrate into the biting inlet of the swing block. Thus, when bending the waste edge, the end of the pressing slide rod can generate a pressing force on the end edge of the waste edge. Further, when the inner wall of the biting inlet bends the waste edge upward or downward, the pressing slide rod will make the waste edge move away from the fixed plate, so that the tearing belt between the waste edge and the finished metal sheet material can be quickly separated.

[0038] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to 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. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0039] Please refer to Figure 1 - Figure 12, the present invention provides a technical solution: a rigging combination automatic processing device, including a machine base 1. A guide rail is installed on the top of the machine base 1, and a transverse movement plate is slidably connected to the guide rail through a mounting slider. A translation mechanism is installed on the machine base 1, and the translation mechanism is composed of a servo motor and a ball screw pair. The ball screw pair is installed at the bottom of the transverse movement plate. The servo motor drives the ball screw pair to rotate, thereby driving the transverse movement plate to move horizontally on the machine base 1. The top surface of the transverse movement plate is connected to a spindle base, and the spindle base is composed of a base body 9, a cover plate 10, and a connecting seat 8. The base body 9 is connected to the top surface of the transverse movement plate. The two sides of the base body 9 are open. The cover plate 10 is installed at the opening on one side of the base body 9, and the connecting seat 8 is connected to the opening on the other side of the base body 9, so that the inner cavities of the cover plate 10, the base body 9, and the connecting seat 8 are closed. Two transmission shafts 13 are rotatably connected in the base body 9 from top to bottom in sequence. Two spindle mounting seats 17 are installed in the inner cavity of the connecting seat 8 from top to bottom in sequence. A spindle 16 is rotatably connected in the two spindle mounting seats 17. One end of the spindle 16 passing through the inner cavity of the base body 9 is connected to the transmission shaft 13 through a universal coupling 15. When the transmission shaft 13 rotates, the universal coupling 15 drives the spindle 16 to rotate. One end of the transmission shaft 13 is installed on the cover plate 10 through a bearing seat to support the transmission shaft 13. In addition, transmission gears 14 are fixedly sleeved on the periphery of the transmission shaft 13, and the two transmission gears 14 are in an external meshing state. A driving motor 11 is installed on the outer wall of the cover plate 10. The motor shaft of the driving motor 11 penetrates into the inner cavity of the base body 9 and is fixedly installed with a driving gear 12. The driving gear 12 is externally meshed with one of the transmission gears 14. In this way, when the motor shaft of the driving motor 11 rotates, the driving gear 12 will rotate, drive one of the transmission gears 14 to rotate, and then drive the transmission shaft 13 to rotate through the meshing transmission of the two transmission gears 14. Then, the transmission shaft 13 drives the universal coupling 15 to rotate, thereby driving the spindle 16 to rotate. In addition, the motor shaft of the servo motor rotates to drive the spindle base to move horizontally, thereby adjusting the installation position of the spindle base;

[0040] One end of the spindle 16 passing through the connecting seat 8 is connected to a connecting flange 26 by means of screws (in combination Figure 1 , Figure 2 and Figure 8 ), the connecting flange 26 is coaxial with the spindle 16. The side wall of the connecting seat 8 is connected to a fixing plate 7 by means of screws. An avoidance groove for the free passage of the connecting flange 26 is provided on the surface of the fixing plate 7. In addition, one end of the connecting flange 26 away from the spindle 16 is coaxially fixed with a connecting shaft 5. The connecting shaft 5 passes through the fixing plate 7 and rotates freely. In addition, a disc cutter 6 is slidably sleeved on the periphery of the connecting shaft 5. The cutting edges of the two disc cutters 6 are arranged oppositely (as Figure 6As shown in the figure, when the metal sheet passes through the two disc cutters 6, the shearing edges of the two disc cutters 6 will bite the metal sheet and shear the metal sheet. At the same time, the disc cutter 6 is key-connected to the connecting shaft 5. The peripheries of the two connecting shafts 5 are respectively sleeved with an upper pressure roller 18 and a lower pressure roller 3 in a sliding manner. A material-biting port 22 is formed between the upper pressure roller 18 and the lower pressure roller 3 (as shown in Figure 7 As shown). The end faces of the upper pressure roller 18 and the lower pressure roller 3 are respectively in abutting connection with the two disc cutters 6. The peripheries of the connecting shafts 5 are sleeved with two stop nuts 21 in a threaded manner. The stop nuts 21 are used to fix the disc cutters 6 on the peripheries of the connecting shafts 5. The end faces of the two stop nuts 21 on the connecting shafts 5 are respectively in abutment with the end faces of the upper pressure roller 18 (lower pressure roller 3) and the disc cutter 6. Thus, the stop nuts 21 fix the disc cutter 6 and the upper pressure roller 18 (lower pressure roller 3) on the connecting shaft 5. In addition, an outwardly turned retaining ring 23 is coaxially fixed to one end of the upper pressure roller 18 and the lower pressure roller 3 away from the fixing plate 7;

[0041] The outer wall of the fixing plate 7 is connected to a support 2 by means of screws. The support 2 is arranged on one side in the radial direction of the disc cutter 6. The outer contour of the support 2 is U-shaped. A swing sleeve 28 is arranged in the middle defective part of the support 2 (as shown in Figure 9 As shown). Two support pivots 29 are fixedly connected to both sides of the periphery of the swing sleeve 28. The support pivots 29 are rotatably connected to both sides of the support 2 through mounting bearings, so that the swing sleeve 28 can rotate up and down. An installation shaft 35 is coaxially rotatably connected to the swing sleeve 28 through a mounting bearing. A swing block 19 is fixedly connected to one end of the installation shaft 35 away from the fixing plate 7. A material-biting port 25 in the form of a notch is formed at one end of the swing block 19 away from the fixing plate 7. A fixed hinge seat 20 is connected to the outer wall of the fixing plate 7 by means of screws. A connecting block 27 is rotatably connected to the outer wall of the fixed hinge seat 20. One end of the connecting block 27 is connected to a driving element 4. The output end of the driving element 4 is fixedly connected to a movable block 24. The movable block 24 is hinged to the periphery of the swing sleeve 28. In this embodiment, the driving element 4 can be selected as a cylinder. The driving element 4 drives the movable block 24 to reciprocate up and down, so that the movable block 24 drives the swing sleeve 28 to rotate around the axis of the support pivot 29, and then the swing sleeve 28 drives the swing block 19 to swing up and down;

[0042] A small gear 30 is fixedly sleeved at one end of the mounting shaft 35 away from the swing block 19. An arc-shaped rack 33 is fixedly connected to the inner wall of one side of the support 2. The center of the arc of the arc-shaped rack 33 is coaxial with the support pivot 29. The small gear 30 is externally meshed with the arc-shaped rack 33. Further, a pressing slide rod 34 is slidably and coaxially inserted into the mounting shaft 35. One end of the pressing slide rod 34 penetrates to the biting port 25, and a ball 37 is rotatably installed at the other end. A special-shaped block 31 is fixedly connected to the surface of the support 2. A rolling groove 32 in the form of a notch is formed on the surface of the special-shaped block 31 facing the swing sleeve 28. The longitudinal distance between the inner walls of the upper and lower sides of the rolling groove 32 increases sequentially in the direction away from the fixed plate 7. A stop screw sleeve 38 is sleeved on the periphery of the pressing slide rod 34 in a threaded manner. An elastic member 36 is provided between the end face of the stop screw sleeve 38 and the end face of the mounting shaft 35. The elastic member 36 can be a spring. The elastic member 36 has an elastic abutting force on the stop screw sleeve 38 in the direction of the special-shaped block 31, so that the ball 37 is in rolling contact with the inner wall of the rolling groove 32 of the special-shaped block 31. And in the initial state, the ball 37 is in rolling contact with the inner wall of the side with the smallest longitudinal distance dimension of the rolling groove 32.

[0043] The working principle of the present invention:

[0044] The end of the strip-shaped metal sheet to be processed is inserted into the material biting port 22 formed by the upper pressure roller 18 and the lower pressure roller 3. In the initial state, the position of the swing block 19 is as shown in Figure 6 or Figure 7 shown, that is, the swing block 19 is in a horizontal state. The driving motor 11 is started. The motor shaft of the driving motor 11 rotates, and then the two main shafts 16 can be driven to rotate. When the main shaft 16 rotates, the connecting shaft 5 is synchronously driven to rotate. When the connecting shaft 5 rotates, the disc cutter 6 is driven to rotate. When the disc cutter 6 rotates, a biting force is generated on the metal sheet. At the same time, the upper pressure roller 18 and the lower pressure roller 3 press the two surfaces of the metal sheet in the thickness direction. The retaining ring 23 limits the edge of the metal sheet. When the metal sheet is bitten by the disc cutter 6, the upper pressure roller 18 and the lower pressure roller 3, it will pass through the disc cutter 6. The cutting edge of the disc cutter 6 will cut one edge of the metal sheet in the width direction. The cut waste edge will penetrate into the biting port 25;

[0045] Then, the driving element 4 is activated. The driving element 4 drives the movable block 24 to reciprocate up and down. When the movable block 24 reciprocates up and down, it will drive the swing sleeve 28 to rotate slightly around the axis of the support pivot 29. When the swing sleeve 28 reciprocates up and down with small amplitude, it will synchronously drive the swing block 19 to rotate. In this way, the inner walls on the upper and lower sides of the bite inlet 25 alternately generate longitudinal extrusion forces on the waste edge, so that the waste edge swings up and down with the swing block 19. If a tear band is generated between the finished product and the waste edge, at this time, the waste edge will swing up and down with small amplitude along the position of the tear band, which is equivalent to bending and deforming the waste edge, so that the tear band can be disconnected, enabling the waste edge to be separated from the finished product. In addition, it should be noted that the longitudinal spacing dimension between the upper and lower sides of the bite inlet 25 is greater than the thickness dimension of the metal sheet, so that the waste edge of the metal sheet can smoothly enter the bite inlet 25;

[0046] When the swing sleeve 28 reciprocates up and down, it will cause the pinion 30 and the arc rack 33 to mesh and drive, thereby driving the mounting shaft 35 to rotate reciprocally with small amplitude. In this way, the inner walls on the upper and lower sides of the bite inlet 25 on the swing block 19 reciprocally generate extrusion forces that cause torsional deformation on the waste edge, and the direction of the extrusion force changes reciprocally, which is equivalent to straightening the waste edge, so that the waste edge will not generate large bending deformation in its length direction, facilitating the subsequent collection of the waste edge. At the same time, due to the waste edge being subjected to forces in multiple directions, the separation of the waste edge from the finished product is relatively smooth, reducing the generation of tear bands;

[0047] In addition, when the swing sleeve 28 swings upward or downward, it is subjected to the elastic abutting force of the elastic member 36 on the stop sleeve 38, so that the ball 37 rolls in contact with the rolling groove 32 of the special-shaped block 31. When the ball 37 is squeezed by the inner wall of the rolling groove 32, the extrusion slide rod 34 will move in the direction of penetrating into the inside of the bite inlet 25. In this way, the extrusion slide rod 34 squeezes the edge of the waste edge, so that when the waste edge bends upward and downward, the extrusion slide rod 34 squeezes the edge of the waste edge, thereby generating a horizontal extrusion force on the waste edge in the direction away from the fixed plate 7, so that the shear force on the tear band between the waste edge and the finished product is relatively large, enabling the tear band to be quickly separated. In addition, since the extrusion slide rod 34 does not penetrate into the bite inlet 25 when the swing block 19 is in a horizontal state, the extrusion slide rod 34 will not interfere with the waste edge and cause the waste edge to be unable to smoothly penetrate into the bite inlet 25. In addition, by the extrusion slide rod 34 generating alternating extrusion forces with the same magnitude and opposite directions on the edge of the waste edge, a squeezing force similar to straightening is generated on the end of the waste edge, making it difficult for the end edge of the waste edge to curl. Especially for thin-walled metal sheets, the finished metal sheet after being sheared can be wound by an external winding device, while the waste edge is collected by workers.
