Description

Technical Field

[0001] The invention relates to the technical field of bearing processing, in particular to a pipe cutting mechanism for bearing processing and manufacturing. Background Art

[0002] Bearing steel pipe refers to hot-rolled or cold-rolled seamless steel pipe, which is used for manufacturing ordinary rolling bearing rings. Through pipe cutting mechanism, the long seamless steel pipe is cut into equal-length bearing rings, instead of single-piece forging or round steel turning, which can save metal, simplify bearing manufacturing process and reduce bearing cost.

[0003] A bearing cutting device for motor bearing processing with patent application number 202220413397.7 mainly includes a base and a fixing mechanism. The base is provided with a movable cutting device and a feed trough plate for placing pipes. The fixing mechanism includes a support frame, a worm rotatably connected to the support frame, and a plurality of fixed components driven by the worm and movable in a vertical direction.

[0044] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0045] Embodiment 1

[0046] Please refer to the accompanying drawings, the present invention provides a technical solution:

[0047] A pipe cutting mechanism for bearing processing and manufacturing includes a base 100, a horizontal workbench 104 is fixed above the base 100 through a support frame 103, and a movable cutting assembly is provided at the front end of the workbench 104;

[0048] A material pushing assembly is provided on the rear side of the top surface of the workbench 104, a first fixing frame 200 is fixed in the middle, a pressing assembly is provided on the first fixing frame 200, a second fixing frame 300 is fixed on the front side of the workbench 104, and two collecting troughs 101 are symmetrically provided on the base 100 corresponding to the lower position of the second fixing frame 300;

[0049] The upper part of the second fixed frame 300 is connected to a lifting plate 302 through two symmetrical and vertically arranged hydraulic telescopic rods 301, the lower part of the lifting plate 302 is connected to a material pressing table 305 through an adjusting component, and vertical racks 306 are symmetrically fixed on both sides of the bottom of the lifting plate 302;

[0050] A support platform 401 is provided below the pressing platform 305, the gap between the support platform 401 and the workbench 104 is set as a cutting groove, and the movable cutting assembly is located at the cutting groove, and a knife moving groove is provided in the middle of the bottom surface of the pressing platform 305, and the knife moving groove is located above the cutting groove;

[0051] A front end plate 400 is fixed to the front side of the second fixed frame 300 at a position corresponding to the supporting platform 401, and a rotating connection component is symmetrically arranged on the inner side of the front end plate 400, and shaft holes are symmetrically arranged on both sides of the supporting platform 401, and the shaft holes are correspondingly connected to the rotating connection components, and the two racks 306 are respectively connected to the rotating connection components on both sides;

[0052] A plurality of V-shaped grooves are evenly arranged on the opposite surfaces of the material supporting platform 401 and the material pressing platform 305, and a plurality of V-shaped grooves are also evenly arranged on the top surface of the workbench 104. The positions of the grooves on the workbench 104, the material supporting platform 401 and the material pressing platform 305 correspond one to one. By setting the V-shaped grooves, a plurality of pipe fittings can be limited in position and placed, and the left and right positions of the pipe fittings can be restricted, so as to quickly determine the position of the pipe fittings and perform operations such as pressing and positioning.

[0053] When cutting the pipe fittings, multiple pipe fittings are evenly placed in the middle of the top surface of the workbench 104, with the rear end abutting against the material pushing assembly, the front end located on the top of the material supporting platform 401, and the pipe fitting cutting position is located at the cutting groove between the workbench 104 and the material supporting platform 401, and the pipe fittings are clamped and limited by the clamping assembly in the middle of the workbench 104 to prevent the pipe fittings from moving at will;

[0054] According to the diameter of the pipe fittings, the height position of the pressing table 305 is adjusted by adjusting the assembly so that the pressing table 305 can be pressed tightly against the top of multiple pipe fittings. The pipe fittings are stably positioned by the support table 401 and the pressing table 305 for subsequent cutting processing.

[0055] Start the mobile cutting assembly and move it from right to left along the cutting groove and the knife shifting groove to cut and cut off multiple pipe fittings. The cut-off part of the pipe fittings is located on the supporting platform 401, and the mobile cutting assembly is located on the left side. Then cancel the connection between the rotating rod connecting assembly on the right side and the right side axis hole of the supporting platform 401, and start the hydraulic telescopic rod 301 to drive the lifting plate 302, the pressing platform 305, and the rack 306 to move upward. The pressing platform 305 cancels the positioning of the pipe fitting, and the rack 306 drives the rotating connecting assembly on the left side, so that the supporting platform 401 drives the cut-off part of the pipe fitting to rotate to the lower right around the left side axis hole to tilt, so that the cut-off part of the pipe fitting can roll along the inclined supporting platform 401 and fall into the collection trough 101 below to complete the unloading and collection.

[0056] While the pressing table 305 moves up and the supporting table 401 rotates to unload materials, the pushing assembly is started to push the multiple pipe fittings to the front side for a certain distance so that the upper and lower cutting positions of the pipe fittings can be moved to the cutting groove. Then the hydraulic telescopic rod 301 drives the lifting plate 302, the pressing table 305 and the rack 306 to move down. At the same time, the supporting table 401 is rotated back to its original position and is in a horizontal position through the action of the rack 306, and the rotating connection assembly on the rear side is connected to the axial hole of the supporting table 401 again, so that both sides of the supporting table 401 are restricted by the rotating connection assembly, thereby improving the position stability of the supporting table 401, and the pipe fittings are pressed and positioned again through the return of the supporting table 401 and the pressing table 305.

[0057] The movable cutting assembly is started again and moves from left to right to perform cutting work. After moving to the right position, the rotating connection assembly on the left side of the support platform 401 is disengaged from the left side axis hole of the support platform 401, and through the same process, the pressing table 305 is moved up, and the support platform 401 rotates to the lower left side to unload the material.

[0058] The present invention realizes synchronous driving of the support platform 401 and the pressing platform 305 by setting two rotating connection components, and enables the support platform 401 to rotate to the left and right alternately to cooperate with the reciprocating movement of the movable cutting component, thereby realizing the cutting process of the pipe fittings in both the outward and return strokes, avoiding the idle return of the movable cutting component, and improving the efficiency of the cutting process.

[0059] The present invention can adjust the position of the pipe by the pushing assembly while the pressing table 305 moves upward and the supporting table 401 rotates to unload the material, so that the cooperation of the various structures of the pipe cutting mechanism is tighter, and the interval time between two adjacent cuttings is shortened, thereby further improving the processing efficiency.

[0060] The rotating connection assembly includes a rotating cylinder 407 rotatably connected to the front end plate 400, a second gear ring 409 is fixed on the inner section of the rotating cylinder 407, and the second gear ring 409 is meshed with the rack 306 on the corresponding side, a rotating shaft 402 is slidably connected in the rotating cylinder 407, and a plurality of limiting slide grooves 406 are evenly arranged on the rotating shaft 402 along the circumferential direction, and a limiting slider 408 is correspondingly fixed on the inner side wall of the shaft hole of the supporting platform 401 and the inner side wall of the rotating cylinder 407, and the limiting slider 408 is slidably connected in the limiting slide groove 406;

[0061] Both ends of the rotating shaft 402 extend out of the rotating cylinder 407, and the inner end extends into the axial hole of the supporting platform 401, and the rotating shaft 402 is rotatably connected to the position close to the supporting platform 401, and the side of the movable plate 404 away from the rotating shaft 402 is connected to the front end plate 400 through a spring, and two guide shafts 403 are fixed, and the front ends of the two guide shafts 403 extend out of the front end plate 400 and are slidably connected to the front end plate 400, and second electromagnets 405 are respectively fixed at the relative positions of the movable plate 404 and the front end plate 400, and the second electromagnet 405 is electrically connected to a power supply and a switch.

[0062] When the second electromagnet 405 is powered off, the end of the rotating shaft 402 extends into the shaft hole of the support platform 401 under the action of the spring and the moving plate 404, thereby limiting the position of the support platform 401 so as to support and position multiple pipes. When the support platform 401 needs to rotate around the rotating shaft 402 on one side, the second electromagnet 405 on the other side is energized to attract each other, so that the moving plate 404 drives the rotating shaft 402 to move and detach from the shaft hole of the support platform 401. Then, when the lifting plate 302 drives the rack 306 to move downward, the second gear ring 409 is driven to rotate through the rack 306.

[0063] Among them, when the rotating shaft 402 is disengaged from the shaft hole, it is in an idling state and does not drive the supporting platform 401. The rotating shaft 402 connected on the other side and the limiting slider 408 and the limiting slide groove 406 drive the supporting platform 401 to rotate so as to rotate and unload materials and return to the original position. After returning to the original position, the energized second electromagnet 405 is de-energized again, so that the detached rotating shaft 402 returns to the original position and extends into the corresponding shaft hole.

[0064] A third electromagnet 410 may be provided on opposite sides of the support platform 401 and the workbench 104. The third electromagnets 410 repel each other when energized, thereby limiting the front and rear positions of the support platform 401 through the repulsive effect, thereby preventing it from moving randomly and affecting the operation of structures such as the mobile cutting assembly.

[0065] Embodiment 2

[0066] The structure of this embodiment is basically the same as that of the first embodiment, except that the clamping assembly includes a spring plate 201 connected to the bottom of the first fixed frame 200 through multiple springs, and the bottom surface of the spring plate 201 is rotatably connected to a pressure roller 205. The pressure roller 205 is evenly provided with multiple annular grooves, and the cross-sectional shape of the annular grooves is V-shaped so as to be in close contact with the tops of multiple pipe fittings, limit the left and right positions of the pipe fittings, and improve the limiting and clamping effects. Spring rods 203 are symmetrically fixed on both sides of the top surface of the spring plate 201, and the top ends of the spring rods 203 extend out of the first fixed frame 200 and are fixed with a limiting plate 204. First electromagnets 202 are fixed at relative positions on the top surface of the spring plate 201 and the first fixed frame 200, and the two first electromagnets 202 are electrically connected to a power supply and a switch.

[0067] When placing the pipe fittings on the workbench 104, the upper and lower first electromagnets 202 are energized to attract each other, so that the spring plate 201 moves up along the direction of the spring rod 203, so that the pipe fittings can be smoothly placed between the pressure roller 205 and the workbench 104, and then the first electromagnet 202 is powered off, and the spring plate 201 is pressed tightly on the top of multiple pipe fittings under the action of the spring, which limits the pipe fittings and prevents them from moving. When the pipe fittings move, the pressure roller 205 rotates while maintaining the pressure, without affecting the movement of the pipe fittings.

[0068] The pushing assembly includes a pushing plate 105 slidably connected to the top surface of the workbench 104, and two symmetrical and parallel first screws 106 are threadedly connected at both ends of the pushing plate 105. The first screw 106 is rotatably connected to the top surface of the workbench 104, and the rear end is connected to a motor. When the position of the pipe needs to be adjusted, the motor is started to rotate the first screw 106, so that the pushing plate 105 moves along the front and rear direction of the top surface of the workbench 104 and pushes the pipe to move, so that after each cutting, the position of the pipe can be adjusted in time to move the next cutting position of the pipe to the cutting groove. A pulley can be set at the rear end of the first screw 106, and the two pulleys are connected by a transmission belt, and one of the pulleys is connected to the motor, so as to realize the synchronous rotation of the two first screws 106 and reduce the number of motors.

[0069] The adjusting assembly includes two threaded barrels 303 symmetrically arranged and rotatably connected to the lifting plate 302, a vertical second screw 304 is threadedly connected in the threaded barrel 303, both ends of the second screw 304 extend out of the threaded barrel 303, and the bottom end is fixedly connected to the top surface of the pressing platform 305, a first gear ring 307 is fixed to the lower part of the threaded barrel 303, a second gear 309 is rotatably connected to the middle of the bottom of the lifting plate 302, the second gear 309 is connected to a motor, and first gears 308 are symmetrically meshed on both sides, the two first gears 308 are respectively meshed with the first gear rings 307 on both sides, through the drive of the motor and the transmission of the first gear 308, the second gear 309 and the first gear ring 307, the two threaded barrels 303 rotate at the same time, and then the two second screws 304 can simultaneously drive the supporting platform 401 to move, and adjust the height position of the supporting platform 401 to adapt to pipes of different diameters.

[0070] Embodiment 3

[0072] After the pipe fitting is pressed and positioned, the third screw 503 is rotated by the drive of the motor, so that the movable seat 502 drives the cutting knife 500 and other structures to move in the left and right directions. At the same time, the cutting knife 500 is rotated by the drive of the motor on the movable seat 502 and the transmission of the first bevel gear 501 and the second bevel gear 504, so that multiple pipe fittings can be cut and cut off in sequence during the movement.

[0073] Among them, a third gear 505 is fixed to the end of the two third screw rods 503, and the two third gears 505 are meshed with each other. One of the third gears 505 is connected to the motor, and the motor is fixed to the bottom surface of the workbench 104.
