Description

Technical Field

[0001] The present invention relates to the technical field of machining equipment, and particularly relates to a bending device for machining mechanical equipment. Background Art

[0002] Machining refers to the process of changing the external dimensions or properties of a workpiece through a mechanical device. According to the differences in processing methods, it can be divided into cutting processing and pressure processing. A bending device is a device used to bend steel pipes or steel bars in mechanical equipment;

[0003] However, there are some defects in the existing bending devices. For example:

[0004] The existing bending devices cannot bend multiple workpieces simultaneously, and can only bend the workpieces in a single direction at a time, and cannot bend in multiple directions simultaneously, resulting in a single processing function and slow processing efficiency.

[0005] Therefore, the present invention provides a bending device for machining mechanical equipment to solve the above problems. Summary of the Invention

[0006] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a bending device for machining mechanical equipment to solve the problem of slow processing efficiency of the existing bending device.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0008] A bending device for machining mechanical equipment includes a base, a transverse pushing seat and a bending rotating seat;

[0009] Base: A power component is installed inside the left end of the base, and a workpiece passes through the left end of the base horizontally.

[0010] Transverse pushing seat: The transverse pushing seat is located inside the base and installed at the output end of the power component. The output end of the power component drives the transverse pushing seat to move horizontally. The workpieces are arranged in a circular array around the center of the transverse pushing seat. Clamping bars are arranged in a circular array on the side surface of the transverse pushing seat, and clamping seats are fixed on the clamping bars. The number of the clamping bars and the clamping seats is equal to the number of the workpieces. The workpieces pass through the transverse pushing seat horizontally and then bend away from the center of the transverse pushing seat. After the workpieces are bent, they are movably clamped into the clamping seats. A workpiece clamping component and a workpiece cutting component are installed inside the transverse pushing seat;

[0011] Rotating seat for bending: The rotating seat for bending is rotatably connected to the right end inside the base. The center of the rotating seat for bending and the center of the horizontal pushing seat are on the same straight line. When the horizontal pushing seat moves horizontally, it drives the rotating seat for bending to rotate through a transmission component. The center of the rotating seat for bending horizontally movably passes through a horizontal pushing shaft. A first spring is fixed between one end of the horizontal pushing shaft and the rotating seat for bending. The other end of the horizontal pushing shaft is rotatably connected with a first rotating rod in a circular array. The number of the first rotating rods is equal to the number of the clamping seats. The first rotating rods and the clamping seats are aligned left and right. A turning seat is integrally formed at the upper end of the first rotating rod. The middle end of the first rotating rod is rotatably connected with a second rotating rod. The other end of the second rotating rod is rotatably connected inside the end of the rotating seat for bending;

[0012] Through the above technical solution, the power component drives the horizontal pushing seat to move horizontally left and right. When the horizontal pushing seat moves to the leftmost side, the workpiece clamping component fixes the workpiece. When the horizontal pushing seat moves to the right, it can carry the workpiece and move it to the right to transport the workpiece;

[0013] When the horizontal pushing seat moves to the right, a circle of first rotating rods and turning seats are located in the middle of a circle of workpieces. When the horizontal pushing seat pushes the horizontal pushing shaft to the right, the first rotating rods and the second rotating rods rotate, so that the turning seats push the workpieces to perform the first bending, making the workpieces bend into the clamping seats. When the horizontal pushing seat continues to move to the right, it drives the rotating seat for bending to rotate through the transmission component. The rotating seat for bending drives the first rotating rods and the second rotating rods to rotate in a circle, so that the turning seats push the workpieces to perform the second bending. And the bending direction of the second bending is circumferential, and the bending direction of the first bending is radial. In this way, the workpieces can be bent in different directions at the same time. After the horizontal pushing seat moves to the left for a certain distance, the workpiece cutting component can cut the workpieces. By setting multiple clamping seats, first rotating rods, second rotating rods and turning seats, multiple workpieces can be processed at the same time.

[0014] Preferably, the power component includes a first motor, a central gear, a passive gear, an inner rotating column and a first screw rod. The first motor is fixed on the side of the base. The output end of the first motor rotatably penetrates into the base and is fixed with a central gear. The central gear meshes with a circle of passive gears. The center of the passive gear passes through an inner rotating column. The end of the inner rotating column rotatably penetrates out of the base and is fixed at the end of the first screw rod. The other end of the first screw rod threadedly penetrates through the horizontal pushing seat;

[0015] Through the above technical solution, the first motor is powered on to drive the central gear to rotate. The central gear drives a circle of passive gears to rotate. The passive gear drives the inner rotating column to rotate. The inner rotating column drives the first screw rod to rotate. The first screw rod rotates forward and backward to drive the horizontal pushing seat to move left and right. In this way, the power component drives the horizontal pushing seat to move left and right.

[0016] Preferably, the workpiece clamping assembly includes a second motor and a central disc. The second motor is fixed to the side of the transverse push seat. The output end of the second motor rotatably penetrates into the transverse push seat and is fixed with a central disc. Branches are integrally formed in a circular array on the side of the central disc, and the branches move away from or close to the workpiece.

[0017] Through the above technical solution, when the second motor is powered on and operates, it drives the central disc to rotate. The branches of the central disc abut against the workpiece, thereby abutting and fixing the workpiece in the transverse push seat. When it is necessary to release the workpiece, the second motor drives the central disc to rotate in the reverse direction, so that the branches of the central disc leave the workpiece. In this way, the workpiece is fixed or released by the workpiece clamping assembly.

[0018] Preferably, a buffer assembly is installed at the end of the branch of the central disc.

[0019] The buffer assembly includes a top plate, an inner through rod, and a second spring. The inner through rod is movably inserted into the branch of the central disc. A second spring is fixed between the inner through rod and the inner side of the branch of the central disc. The other end of the inner through rod is fixed with a top plate, and the top plate abuts against the workpiece.

[0020] Through the above technical solution, when the branch of the central disc approaches the workpiece, the top plate contacts the workpiece instead of the branch of the central disc. The branch of the central disc can rotate through a larger angle, so that the second spring pushes the inner through rod forcefully, and the top plate presses the workpiece forcefully.

[0021] Preferably, the workpiece cutting assembly includes a cutting knife and a tool holder. The tool holder is rotatably connected in the transverse push seat. One end of the tool holder is fixed to the output end of the second motor. Cutting knives are fixedly arranged in a circular array at the other end of the tool holder. The number of cutting knives is equal to the number of workpieces, and the workpiece is located within the rotation range of the cutting knives.

[0022] Through the above technical solution, when the second motor drives the central disc to rotate, it also drives the tool holder to rotate. The tool holder drives the cutting knives to rotate. When the top plate just contacts the workpiece, the cutting knives do not contact the workpiece. As the second motor drives the central disc and the tool holder to continue rotating, the inner through rod retracts into the branch of the central disc, so that the cutting knives cut the workpiece. After the cutting is completed, the second motor drives the central disc and the tool holder to rotate in the reverse direction and return to the original position. In this way, the workpiece is cut by the workpiece cutting assembly, and the buffer assembly is used to fix the workpiece before the workpiece cutting assembly cuts the workpiece.

[0023] Preferably, the clamping seat is detachably fixed to the clamping bar through a fixing component. The fixing component includes a second screw rod and a first nut. One end of the second screw rod is fixed to the end of the clamping seat. The inside of the clamping bar is hollow. The other end of the second screw rod movably passes through the clamping bar. A first nut is sleeved on the outer thread of the second screw rod, and the first nut and the clamping seat clamp the clamping bar.

[0024] Through the above technical solution, when the fixed clamp seat is required, the first nut and the clamp seat clamp the clamping bar. When the clamp seat needs to be moved, the first nut is rotated in the reverse direction, so that the first nut and the clamp seat release the clamping bar. Through the fixing component, the clamp seat can be freely moved on the premise of being able to fix the clamp seat, the position of the clamp seat can be adjusted, and then the position of the second bending of the workpiece can be adjusted, that is, the distance between the first bending position and the second bending position of the workpiece is adjusted.

[0025] Preferably, the transmission component includes a passive gear ring, a torsion spring, an active gear, a lower rotating shaft, an inclined plate, a top rod and a lower support plate;

[0026] The passive gear ring is sleeved outside the end of the bending turntable. The passive gear ring is meshed with the active gear in tooth. The active gear is fixed at the end of the lower rotating shaft. The lower rotating shaft rotates through the end of the base. A torsion spring is fixed between the active gear and the side of the base. An inclined plate is fixed at the other end of the lower rotating shaft;

[0027] The upper end of the lower support plate is fixed on the side of the horizontal pushing seat. The lower end of the lower support plate is fixed with a top rod. The inclined surface of the inclined plate is within the moving stroke of the top rod;

[0028] Through the above technical solution, when the horizontal pushing seat drives the lower support plate to move rightward, the lower support plate drives the top rod to move rightward. After the top rod abuts against the inclined surface of the inclined plate, the inclined plate is pushed to rotate around the lower rotating shaft. The inclined plate drives the lower rotating shaft to rotate. The lower rotating shaft drives the active gear to rotate. The torsion spring is twisted. The active gear drives the passive gear ring to rotate. The passive gear ring drives the bending turntable to rotate. When the horizontal pushing seat moves leftward and returns to its position, the top rod leaves the inclined plate, and the torsion spring reversely twists back to the active gear. The active gear drives the passive gear ring to rotate reversely, and then the bending turntable rotates reversely and returns to its position. In this way, the horizontal pushing seat drives the bending turntable to rotate through the transmission component. Firstly, an additional power mechanism does not need to be added to drive the bending turntable to rotate. Secondly, the two movement processes of the horizontal movement of the horizontal pushing seat and the rotation of the bending turntable can be kept synchronous.

[0029] Preferably, one end of the top rod is provided with a thread and movably passes through the lower end of the lower support plate. Two second nuts are sleeved on the threaded end of the top rod. The two second nuts clamp the lower support plate. The top rod is fixed at the lower end of the lower support plate through the two second nuts;

[0030] Through the above technical solution, the left - right position of the ejector rod can be adjusted, and then the initial distance between the ejector rod and the inclined plate can be adjusted. When the initial distance between the ejector rod and the inclined plate is large, the transverse - push seat needs to move a greater distance to the right to drive the turning seat for bending to rotate. That is, when the transverse - push seat moves a greater distance to the right, the turning seat can push the workpiece to perform the second bending. In other words, the second bending of the workpiece can be carried out only after the first bending of the workpiece at a larger angle. Similarly, when the initial distance between the ejector rod and the inclined plate is small, the transverse - push seat only needs to move a smaller distance to the right to drive the turning seat for bending to rotate. That is, when the transverse - push seat moves a smaller distance to the right, the turning seat can push the workpiece to perform the second bending. In other words, the second bending of the workpiece can be carried out after the first bending of the workpiece at a smaller angle. Thus, the angles of the first bending and the second bending can be controlled.

[0031] The beneficial effects of the present invention are as follows:

[0032] 1. The power assembly drives the transverse - push seat to move horizontally left and right. When the transverse - push seat moves to the left - most position, the workpiece clamping assembly fixes the workpiece. When the transverse - push seat moves to the right, it can carry the workpiece to move to the right, thereby transporting the workpiece.

[0033] 2. When the transverse - push seat moves to the right, a circle of first rotating rods and the turning seat are located in the middle of a circle of workpieces. When the transverse - push seat pushes the transverse - push shaft to the right, the first rotating rod and the second rotating rod rotate, causing the turning seat to push the workpiece to perform the first bending, and the workpiece is bent into the clamping seat. When the transverse - push seat continues to move to the right, the turning seat for bending is driven to rotate through the transmission assembly. The turning seat for bending drives the first rotating rod and the second rotating rod to make a circumferential movement, causing the turning seat to push the workpiece to perform the second bending. And the bending direction of the second bending is circumferential, and the bending direction of the first bending is radial. Thus, different - direction bending processing can be carried out on the workpiece simultaneously.

[0034] 3. After the transverse - push seat moves a certain distance to the left, the workpiece cutting assembly can cut the workpiece.

[0035] 4. By setting multiple clamping seats, first rotating rods, second rotating rods and turning seats, multiple workpieces can be processed simultaneously.

[0036] In summary, the present device can perform the first bending and the second bending on multiple workpieces simultaneously, rather than performing the second bending only after the first bending. Therefore, the processing efficiency is higher, and the bending angles of the first bending and the second bending are different, and the bending function is more comprehensive. In addition to bending the workpiece, the device can also cut and drag the workpiece, and the function is more comprehensive. BRIEF DESCRIPTION OF THE DRAWINGS

Detailed implementation manners

[0045] Next, each embodiment of the present invention will be described in detail with reference to the attached Figures 1 to 7 Those skilled in the art should understand that these implementation manners are only used to explain the technical principle of the present invention and are not intended to limit the protection scope of the present invention.

[0046] As shown in the attached Figure 1 - attached Figure 7 figures, a bending device for mechanical equipment processing includes a base 1, a cross-pushing seat 4 and a bending rotating seat 15;

[0047] Base 1: The base 1 is U-shaped. A power assembly 3 is installed inside the left end of the base 1. Eight workpieces 2 horizontally pass through the left end of the base 1 movably. The workpieces 2 move rightward through the left end of the base 1. A controller 17 is fixed on the base 1;

[0048] Transverse pushing seat 4: The transverse pushing seat 4 is located inside the base 1 and is installed at the output end of the power assembly 3. The output end of the power assembly 3 drives the transverse pushing seat 4 to move horizontally. There are clamping bars 9 arranged in a circular array on the side of the transverse pushing seat 4, and a clamping seat 10 is fixed on the clamping bar 9. A clamping groove is provided at the right end of the clamping seat 10. The number of the clamping bars 9 and the clamping seats 10 is equal to the number of the workpieces 2. The workpieces 2 are arranged in a circular array around the center of the transverse pushing seat 4. The workpieces 2 pass through the transverse pushing seat 4 horizontally and then bend away from the center of the transverse pushing seat 4, so that the workpieces 2 are movably clamped into the clamping seats 10 after bending. A workpiece clamping assembly and a workpiece cutting assembly are installed inside the transverse pushing seat 4;

[0049] Bending rotating seat 15: The bending rotating seat 15 is rotatably connected inside the right end of the base 1. The center of the bending rotating seat 15 is on the same straight line as the center of the transverse pushing seat 4. When the transverse pushing seat 4 moves horizontally, it drives the bending rotating seat 15 to rotate through the transmission assembly 18. A transverse pushing shaft 14 horizontally passes through the center of the bending rotating seat 15 movably. A first spring 16 is fixed between one end of the transverse pushing shaft 14 and the bending rotating seat 15. The other end of the transverse pushing shaft 14 is rotatably connected with a first rotating rod 12 in a circular array. The number of the first rotating rods 12 is equal to the number of the clamping seats 10. The first rotating rods 12 are aligned with the clamping seats 10 left and right. A turning seat 11 is integrally formed at the upper end of the first rotating rod 12. One end of the turning seat 11 close to the workpiece 2 is recessed to form a groove, so that the workpiece 2 can be clamped into the turning seat 11. The middle end of the first rotating rod 12 is rotatably connected with a second rotating rod 13, and the other end of the second rotating rod 13 is rotatably connected inside the end of the bending rotating seat 15.

[0050] As shown in the attached Figure 1 attachment Figure 3 and the attached Figure 4 attachment, the power assembly 3 includes a first motor 31, a central gear 32, a passive gear 33, an inner rotating column 34 and a first screw 35. The first motor 31 is fixed on the side of the base 1. The output end of the controller 17 is electrically connected to the input end of the first motor 31. The output end of the first motor 31 rotates into the base 1 and then is fixed with the central gear 32. The central gear 32 meshes with a circle of passive gears 33. The inner rotating column 34 passes through the center of the passive gear 33. The end of the inner rotating column 34 rotates out of the base 1 and is fixed at the end of the first screw 35. The other end of the first screw 35 threadedly passes through the transverse pushing seat 4;

[0051] The working mode of the power assembly 3 is as follows: The controller 17 controls the first motor 31 to be powered on and work to drive the central gear 32 to rotate. The central gear 32 drives a circle of passive gears 33 to rotate. The passive gear 33 drives the inner rotating column 34 to rotate. The inner rotating column 34 drives the first screw 35 to rotate. The first screw 35 rotates forward and backward to drive the transverse pushing seat 4 to move left and right.

[0052] As shown in the attached Figure 3 attachment Figure 5As shown in the figure, the workpiece clamping assembly includes a second motor 19 and a central disk 20. The second motor 19 is fixed to the side of the transverse pushing seat 4. The output end of the controller 17 is electrically connected to the input end of the second motor 19. After the output end of the second motor 19 rotates into the transverse pushing seat 4, a central disk 20 is fixed. On the side of the central disk 20, branches are integrally formed in a circular array, and the branches move away from or close to the workpiece 2.

[0053] The working mode of the workpiece clamping assembly is as follows: The controller 17 controls the second motor 19 to be powered on and work to drive the central disk 20 to rotate. The branches of the central disk 20 abut against the workpiece 2, so as to abut and fix the workpiece 2 in the transverse pushing seat 4. When it is necessary to release the workpiece 2, the second motor 19 drives the central disk 20 to rotate in the reverse direction, so that the branches of the central disk 20 leave the workpiece 2.

[0054] As attached Figure 6 As shown in the figure, a buffer assembly 21 is installed at the end of the branch of the central disk 20;

[0055] The buffer assembly 21 includes a top plate 211, an inner through rod 212 and a second spring 213. The inner through rod 212 is movably inserted into the branch of the central disk 20. A second spring 213 is fixed between the inner through rod 212 and the inner side of the branch of the central disk 20. The other end of the inner through rod 212 is fixed with a top plate 211, and the top plate 211 abuts against the workpiece 2;

[0056] The working mode of the buffer assembly 21 is as follows: When the branch of the central disk 20 approaches the workpiece 2, the top plate 211 contacts the workpiece 2 instead of the branch of the central disk 20, and the branch of the central disk 20 can rotate a larger angle, so that the second spring 213 pushes the inner through rod 212 forcefully, so that the top plate 211 presses the workpiece 2 forcefully.

[0057] As attached Figure 1 And attached Figure 3 As shown in the figure, the workpiece cutting assembly includes a cutting tool 5 and a tool holder 6. The tool holder 6 is rotatably connected in the transverse pushing seat 4. One end of the tool holder 6 is fixed to the output end of the second motor 19. Cutting tools 5 are fixedly arranged in a circular array at the other end of the tool holder 6. The number of cutting tools 5 is equal to the number of workpieces 2, and the workpiece 2 is located within the rotation range of the cutting tools 5;

[0058] The working mode of the workpiece cutting assembly is as follows: When the second motor 19 drives the central disk 20 to rotate, it also drives the tool holder 6 to rotate. The tool holder 6 drives the cutting tools 5 to rotate. When the top plate 211 just contacts the workpiece 2, the cutting tools 5 do not contact the workpiece 2. As the second motor 19 drives the central disk 20 and the tool holder 6 to continue to rotate, the inner through rod 212 retracts into the branch of the central disk 20, so that the cutting tools 5 cut the workpiece 2. After the cutting is completed, the second motor 19 drives the central disk 20 and the tool holder 6 to rotate in the reverse direction and return to the original position.

[0059] As attached Figure 1As shown, the clamping seat 10 is detachably fixed to the clamping bar 9 through a fixing component. The fixing component includes a second screw rod 7 and a first nut 8. One end of the second screw rod 7 is fixed to the end of the clamping seat 10. The inside of the clamping bar 9 is hollow. The other end of the second screw rod 7 movably passes through the clamping bar 9. The second screw rod 7 is externally threaded with a first nut 8, and the first nut 8 and the clamping seat 10 clamp the clamping bar 9.

[0060] The working mode of the fixing component is as follows: when it is necessary to fix the clamping seat 10, the first nut 8 and the clamping seat 10 clamp the clamping bar 9. When it is necessary to move the clamping seat 10, the first nut 8 is rotated in the reverse direction so that the first nut 8 and the clamping seat 10 release the clamping bar 9.

[0061] As shown in the attached Figure 1 attachment Figure 3 and the attached Figure 5 As shown in the attached figures, the transmission component 18 includes a passive gear ring 181, a torsion spring 182, an active gear 183, a lower rotating shaft 184, an inclined plate 185, a push rod 186 and a lower support plate 187.

[0062] The passive gear ring 181 is sleeved outside the end of the bending turntable 15. The passive gear ring 181 is in meshing with the active gear 183. The active gear 183 is fixed to the end of the lower rotating shaft 184. The lower rotating shaft 184 rotatably passes through the end of the base 1. A torsion spring 182 is fixed between the active gear 183 and the side surface of the base 1. The other end of the lower rotating shaft 184 is fixed with an inclined plate 185.

[0063] The upper end of the lower support plate 187 is fixed to the side surface of the horizontal pushing seat 4. The lower end of the lower support plate 187 is fixed with a push rod 186. The inclined surface of the inclined plate 185 is within the moving stroke of the push rod 186.

[0064] The working mode of the transmission component 18 is as follows: the horizontal pushing seat 4 drives the lower support plate 187 to move rightward. The lower support plate 187 drives the push rod 186 to move rightward. After the push rod 186 abuts against the inclined surface of the inclined plate 185, it pushes the inclined plate 185 to rotate around the lower rotating shaft 184. The inclined plate 185 drives the lower rotating shaft 184 to rotate. The lower rotating shaft 184 drives the active gear 183 to rotate. The torsion spring 182 is twisted. The active gear 183 drives the passive gear ring 181 to rotate. The passive gear ring 181 drives the bending turntable 15 to rotate. When the horizontal pushing seat 4 moves leftward to return to its original position, the push rod 186 leaves the inclined plate 185. The torsion spring 182 reversely twists back the active gear 183. The active gear 183 drives the passive gear ring 181 to rotate in the reverse direction, and then the bending turntable 15 rotates in the reverse direction to return to its original position.

[0065] As shown in the attached Figure 1 As shown in the attached figure, one end of the push rod 186 is provided with threads and movably passes through the lower end of the lower support plate 187. The threaded end of the push rod 186 is externally threaded with two second nuts. The two second nuts clamp the lower support plate 187. The push rod 186 is fixed to the lower end of the lower support plate 187 through the two second nuts.

[0066] The working principle of this device is as follows:

[0067] The power component 3 drives the horizontal push seat 4 to move left until the workpiece clamping component reaches the clamping point a of the workpiece 2. At this time, the workpiece clamping component clamps the workpiece 2. Then, the power component 3 drives the horizontal push seat 4 to move right, thereby driving the workpiece 2 to move right. After moving a certain distance, a circle of the first rotating rods 12 and the turning seat 11 are inserted into the middle of a circle of the workpiece 2. As the horizontal push seat 4 continues to move right for a certain distance, the tool holder 6 pushes the horizontal push shaft 14 to the right, and the first rotating rod 12 and the second rotating rod 13 rotate, causing the turning seat 11 to push the workpiece 2 to perform the first bending, bending along the first bending point c, and the workpiece 2 bends in the direction away from the center of the horizontal push seat 4 until the end of the workpiece 2 is bent into the clamping seat 10. As the horizontal push seat 4 continues to move right, the transmission component 18 drives the bending rotating seat 15 to rotate, and the bending rotating seat 15 drives the first rotating rod 12 and the second rotating rod 13 to rotate circumferentially, causing the turning seat 11 to bend the workpiece 2 circumferentially, and the workpiece 2 bends around the clamping seat 10, that is, the second bending point d. The bending angle of the second bending is controlled according to the rightward movement distance of the horizontal push seat 4;

[0068] After the bending is completed, the horizontal push seat 4 moves left for a certain distance, and the workpiece cutting component cuts the workpiece 2. The cutting point is point b. After the cutting is completed, the horizontal push seat 4 continues to move left to return to its original position. At this time, the workpiece 2 can be continuously conveyed into this device until the workpiece clamping component reaches the clamping point a of the workpiece 2 again.
