Description

Technical Field

[0001] This application belongs to the technical field of chamfering equipment, and particularly relates to a double-station pipe chamfering device. Background Art

[0002] Chamfering refers to the machining of cutting the edges of a workpiece into a certain inclined plane. Chamfering is to remove the burrs generated by machining on the part, and also to facilitate the assembly of the part. Generally, chamfers are made at the ends of the part. In the production and manufacturing process of metal workpieces, a large amount of burrs often remain at the edges of the workpiece or the edges of the holes, and chamfering operations need to be performed on the edges of the workpiece. For pipe-shaped metal products, chamfering treatment needs to be carried out on the ends of the pipes. The pipes from the previous process are transported to the chamfering equipment by a transporting device for chamfering. However, traditional chamfering equipment can usually only chamfer one pipe at a time, with low chamfering efficiency and unable to meet the processing requirements of pipes.

[0003] To improve the chamfering efficiency of pipes, some chamfering equipment is provided with two chamfering stations, and a chamfering machine is provided at each chamfering station. Each chamfering machine can independently chamfer the pipe. In addition, a feeding mechanism and a discharging mechanism are provided to feed the two chamfering machines and discharge the pipes after chamfering. When a single feeding mechanism feeds the two chamfering machines, it is necessary to first transport the pipe to one chamfering machine and then transport another pipe to the other chamfering machine. When feeding one chamfering machine, the other chamfering machine needs to wait, and the same is true for the discharging process, which increases the waiting time of the chamfering machine. Moreover, the feeding and discharging processes of traditional chamfering equipment are cumbersome, further affecting the chamfering efficiency of the chamfering equipment. Summary of the Utility Model

[0004] This application provides a double-station pipe chamfering device to solve the technical problem that the chamfering efficiency of traditional pipe chamfering equipment is low due to low feeding and discharging efficiency.

[0005] The technical solution adopted in this application is as follows:

[0006] A double-station pipe chamfering device includes a frame, two symmetrically arranged chamfering units installed on the frame, and a material distribution unit located between the two chamfering units. The chamfering unit includes a feeding end and a discharging end, as well as a material transporting truss, a feeding mechanism, a chamfering mechanism, and a discharging mechanism. The material distribution unit can respectively transport pipes to the feeding mechanisms of the two chamfering units. The chamfering mechanism includes a fixing member for fixing the pipe and a chamfering member for chamfering the pipe. The feeding mechanism can reciprocate along the material transporting truss between the feeding end and the chamfering mechanism to transport the pipe to the chamfering mechanism. The discharging mechanism can reciprocate along the material transporting truss between the chamfering mechanism and the discharging end to transport the pipe of the chamfering mechanism to the discharging end.

[0007] The double-station pipe chamfering device described in this application further includes the following additional technical features:

[0008] The fixing member includes a clamping portion and a rotating portion. The clamping portion can clamp the pipe and drive the pipe to rotate self-rotation under the rotation of the rotating portion. The chamfering member includes a cutter, and the cutter can abut against the end of the pipe and chamfer the end of the pipe along with the self-rotation of the pipe.

[0009] Each chamfering unit includes two chamfering members, and the two chamfering members are respectively arranged on both sides of the fixing member.

[0010] The clamping portion is annular and is provided with a clamping through hole for the pipe to pass through. The clamping portion has a locking state in which it abuts against the pipe and an unlocking state in which it separates from the pipe, and the clamping portion can switch between the locking state and the unlocking state to clamp and release the pipe.

[0011] One of the loading mechanism and the material transporting gantry is provided with a first guiding slide rail, and the other of the two is provided with a first guiding chute adapted to the first guiding slide rail. The loading mechanism reciprocates between the loading end and the chamfering mechanism through the sliding cooperation of the first guiding slide rail and the first guiding chute.

[0012] The loading mechanism includes a first driving motor, a first moving seat, and a pipe bearing seat connected to the first moving seat. The first guiding chute is arranged on the first moving seat, the first guiding slide rail is arranged on the material transporting gantry, and the first driving motor drives the first moving seat to reciprocate on the material transporting gantry.

[0013] The loading mechanism further includes a pneumatic push rod arranged on the pipe bearing seat, and the pneumatic push rod can push the pipe to move towards the fixing member.

[0014] One of the unloading mechanism and the material transporting gantry is provided with a second guiding slide rail, and the other of the two is provided with a second guiding chute adapted to the second guiding slide rail. The unloading mechanism reciprocates between the chamfering mechanism and the unloading end through the sliding cooperation of the second guiding slide rail and the second guiding chute.

[0015] The unloading mechanism includes a second driving motor, a second moving seat, and a tensioning and fixing member connected to the second moving seat. The second guiding chute is arranged on the second moving seat, the second guiding slide rail is arranged on the material transporting gantry, and the tensioning and fixing member includes a plurality of tensioning plates. The tensioning plates abut against the inner wall of the pipe and fix the pipe to the tensioning and fixing member by friction.

[0016] The tension fixing member is connected to the second moving seat through a rotating member. The rotating member includes a rotating gear. The tension fixing member is connected to the output shaft of the rotating gear and synchronously flips with the rotation of the rotating gear.

[0017] Due to the adoption of the above technical solution, the beneficial effects obtained by this application are as follows:

[0018] 1. The double-station pipe chamfering device of this application includes two symmetrically arranged chamfering units, which can respectively chamfer two pipes. The feeding unit transports pipes to the feeding mechanisms of the two chamfering units respectively. The feeding mechanism reciprocates between the receiving end and the chamfering mechanism along the feeding truss to transport the pipes to the fixing member. Since each chamfering unit is provided with an independent material transporting truss and a feeding mechanism, each feeding mechanism can realize independent feeding to the chamfering mechanism, greatly improving the pipe transportation efficiency to the chamfering mechanism, thereby improving the chamfering efficiency of the chamfering device; Similarly, each discharging mechanism can realize independent discharging from the chamfering mechanism. After the chamfering mechanism completes chamfering the pipe, the discharging mechanism transports the pipe to the discharging end to realize the transportation of the chamfered pipe. Each discharging mechanism can realize independent discharging from the chamfering mechanism, greatly improving the pipe output efficiency of the chamfering mechanism and further improving the operation efficiency of the chamfering device; In addition, by setting the material transporting truss, while providing a movement platform for the feeding mechanism and the discharging mechanism, it restricts the movement directions of the two, so that the feeding mechanism and the discharging mechanism can only move along the extension direction of the material transporting truss, which is convenient for improving the reciprocating movement efficiency of the feeding mechanism between the feeding end and the chamfering mechanism and the discharging mechanism between the chamfering mechanism and the discharging end, so as to timely provide the chamfering mechanism with pipes to be chamfered and timely transport the chamfered pipes out, improving the pipe chamfering efficiency of the chamfering device.

[0019] 2. As a preferred embodiment of this application, the fixing member is set to include a clamping portion and a rotating portion. When the feeding mechanism transports the pipe to the fixing member, the clamping portion can clamp the pipe to fix the pipe, and the rotating portion drives the clamping portion to rotate, so that the pipe clamped by the clamping portion rotates. Since the tool abuts against the end of the pipe, with the rotation of the pipe, relative friction occurs between the tool and the end of the pipe, thereby realizing chamfering of the end of the pipe. That is, chamfering of the pipe is realized by driving the pipe to rotate through the cooperation of the rotating portion and the clamping portion. During the chamfering process, the position of the chamfering member does not change, reducing the working space occupied during the pipe chamfering process, optimizing the structural design of the chamfering unit, and contributing to the miniaturization of the chamfering device.

[0020] 3. As a preferred embodiment of the present application, two chamfering members are provided in each chamfering unit, and the chamfering members are placed on both sides of the fixing member. The cutters of the two chamfering members respectively abut against the two ends of the pipe. As the pipe rotates, the cutters achieve grinding of the two ends of the pipe through friction, enabling simultaneous chamfering of the two ends of the pipe, shortening the chamfering time required for a single pipe, and further improving the chamfering efficiency of the chamfering mechanism.

[0021] 4. As a preferred embodiment of the present application, by providing the first guiding slide rail and the first guiding chute, the feeding mechanism can achieve reciprocating movement along the material transporting truss through the sliding cooperation between the two, reducing the frictional resistance suffered by the feeding mechanism during the movement process, thereby achieving rapid reciprocating movement between the feeding end and the chamfering mechanism and improving the feeding efficiency; in addition, by providing the first guiding slide rail and the first guiding slider, the movement direction of the feeding mechanism can be restricted, preventing the feeding mechanism from deviating during the movement process and ensuring that the pipe can be accurately conveyed to the fixing member, improving the pipe conveying accuracy of the feeding mechanism.

[0022] 5. As a preferred embodiment of the present application, by providing the second guiding slide rail and the second guiding chute, the discharging mechanism can achieve reciprocating movement along the material transporting truss through the sliding cooperation between the two, reducing the frictional resistance suffered by the discharging mechanism during the movement process, thereby achieving rapid reciprocating movement between the discharging end and the chamfering mechanism and improving the discharging efficiency; in addition, by providing the second guiding slide rail and the second guiding chute, the movement direction of the discharging mechanism can be restricted, preventing the discharging mechanism from deviating during the movement process and ensuring that the discharging mechanism can accurately pick up the pipe from the fixing member and convey it to the discharging end, improving the pipe conveying accuracy of the discharging mechanism.

[0045] As Figures 1 to 6 shown, a double-station pipe chamfering device includes a frame 1, two symmetrically arranged chamfering units 2 installed on the frame 1, and a material distribution unit 3 located between the two chamfering units 2. The chamfering unit 2 includes a loading end 21 and a discharging end 22, as well as a material transporting truss 4, a loading mechanism 5, a chamfering mechanism 6, and a discharging mechanism 7. The material distribution unit 3 can respectively convey pipes 9 to the loading mechanisms 5 of the two chamfering units 2. The chamfering mechanism 6 includes a fixing member 61 for fixing the pipe 9 and a chamfering member 62 for chamfering the pipe 9. The loading mechanism 5 can reciprocate along the material transporting truss 4 between the loading end 21 and the chamfering mechanism 6 to convey the pipe 9 to the chamfering mechanism 6. The discharging mechanism 7 can reciprocate along the material transporting truss 4 between the chamfering mechanism 6 and the discharging end 22 to convey the pipe 9 of the chamfering mechanism 6 to the discharging end 22.

[0046] The double-station pipe chamfering device of the present application includes two symmetrically arranged chamfering units 2, which can perform chamfering operations on two pipes 9 respectively. The material distribution unit 3 conveys the pipes 9 to the feeding mechanisms 5 of the two chamfering units 2 respectively. The feeding mechanism 5 reciprocates between the receiving end and the chamfering mechanism 6 along the feeding truss to convey the pipe 9 to the fixing member 61. Since each chamfering unit 2 is provided with an independent material conveying truss 4 and a feeding mechanism 5, each feeding mechanism 5 can achieve separate feeding to the chamfering mechanism 6, greatly improving the conveying efficiency of the pipe 9 to the chamfering mechanism 6, thereby improving the chamfering efficiency of the chamfering device; similarly, each discharging mechanism 7 can achieve separate discharging from the chamfering mechanism 6. After the chamfering mechanism 6 completes the chamfering of the pipe 9, the discharging mechanism 7 transports the pipe 9 to the discharging end 22 to realize the transportation of the chamfered pipe 9. Each discharging mechanism 7 can achieve separate discharging from the chamfering mechanism 6, greatly improving the output efficiency of the pipe 9 of the chamfering mechanism 6 and further improving the operation efficiency of the chamfering device; in addition, by setting the material conveying truss 4, while providing a movement platform for the feeding mechanism 5 and the discharging mechanism 7, the movement directions of the two are restricted, so that the feeding mechanism 5 and the discharging mechanism 7 can only move along the extension direction of the material conveying truss 4, which is convenient for improving the reciprocating movement efficiency of the feeding mechanism 5 between the feeding end 21 and the chamfering mechanism 6 and the discharging mechanism 7 between the chamfering mechanism 6 and the discharging end 22, thereby timely providing the pipe 9 to be chamfered for the chamfering mechanism 6 and timely transporting the chamfered pipe 9 out, improving the chamfering efficiency of the pipe 9 of the chamfering device.

[0047] As a preferred embodiment of the present application, as Figure 5 shown, the fixing member 61 includes a clamping portion 611 and a rotating portion 612. The clamping portion 611 can clamp the pipe 9 and drive the pipe 9 to rotate selflessly under the rotation of the rotating portion 612. The chamfering member 62 includes a cutter 621. The cutter 621 can abut against the end of the pipe 9 and realize chamfering of the end of the pipe 9 along with the self-rotation of the pipe 9.

[0048] The fixing member 61 is set to include a clamping portion 611 and a rotating portion 612. When the feeding mechanism 5 transports the pipe 9 to the fixing member 61, the clamping portion 611 can clamp the pipe 9 to fix the pipe 9, and drive the clamping portion 611 to rotate through the rotating portion 612, so that the pipe 9 clamped by the clamping portion 611 rotates selflessly. Since the cutter 621 abuts against the end of the pipe 9, with the self-rotation of the pipe 9, relative friction occurs between the cutter 621 and the end of the pipe 9, thereby realizing chamfering of the end of the pipe 9, that is, by the cooperation of the rotating portion 612 and the clamping portion 611 to drive the pipe 9 to rotate selflessly to realize chamfering of the pipe 9. The position of the chamfering member 62 does not change during the chamfering process, reducing the working space occupied during the chamfering process of the pipe 9, optimizing the structural design of the chamfering unit 2, and contributing to the miniaturization of the chamfering device.

[0049] As a preferred embodiment of this embodiment, as Figure 1 shown, each chamfering unit 2 includes two chamfering members 62, and the two chamfering members 62 are respectively arranged on both sides of the fixing member 61. By arranging two chamfering members 62 in each chamfering unit 2 and placing the chamfering members 62 on both sides of the fixing member 61, the cutting tools 621 of the two chamfering members 62 respectively abut against the two ends of the pipe 9. As the pipe 9 rotates, the cutting tools 621 achieve grinding of the two ends of the pipe 9 through friction, enabling simultaneous chamfering of the two ends of the pipe 9, shortening the chamfering time required for a single pipe 9, and further improving the chamfering efficiency of the chamfering mechanism 6.

[0050] As another preferred embodiment of this embodiment, as Figure 5 shown, the clamping portion 611 is annular and is provided with a clamping through hole 6111 for the pipe 9 to pass through. The clamping portion 611 has a locking state in which it abuts against the pipe 9 and an unlocking state in which it is separated from the pipe 9, and the clamping portion 611 can switch between the locking state and the unlocking state to clamp and release the pipe 9. By setting the clamping portion 611 to be annular, it can more evenly wrap the outer wall of the pipe 9 and improve the fixing stability of the pipe 9. When the feeding mechanism 5 transports the pipe 9 into the clamping through hole 6111 and reaches the preset position, the clamping portion 611 switches to the locking state, and the clamping portion 611 tightly abuts against the outer wall of the pipe 9 to fix the pipe 9 through friction. After the chamfering work is completed, the clamping portion 611 switches from the self-locking position to the unlocking position, releases the locking of the pipe 9, and the pipe 9 can be withdrawn from the clamping through hole 6111 and moved towards the discharging end 22 under the drive of the discharging mechanism 7.

[0051] As a preferred embodiment of this application, as Figure 1 、 Figure 2 shown, one of the feeding mechanism 5 and the material transporting gantry 4 is provided with a first guiding slide rail 41, and the other of them is provided with a first guiding chute 54 adapted to the first guiding slide rail 41. The feeding mechanism 5 realizes reciprocating movement between the feeding end 21 and the chamfering mechanism 6 through the sliding cooperation of the first guiding slide rail 41 and the first guiding chute 54.

[0052] By setting the first guiding slide rail 41 and the first guiding chute 54, the feeding mechanism 5 can achieve reciprocating movement along the material conveying truss 4 through the sliding fit between the two, reducing the frictional resistance suffered by the feeding mechanism 5 during the movement process, thereby realizing rapid reciprocating movement between the feeding end 21 and the chamfering mechanism 6 and improving the feeding efficiency. In addition, by setting the first guiding slide rail 41 and the first guiding slider, the movement direction of the feeding mechanism 5 can be restricted, preventing the feeding mechanism 5 from deviating during the movement process and ensuring that the pipe 9 can be accurately conveyed to the fixing member 61, improving the conveying accuracy of the pipe 9 by the feeding mechanism 5.

[0053] As a preferred embodiment under this embodiment, as Figure 4 shown, the feeding mechanism 5 includes a first driving motor 51, a first moving seat 52, and a pipe carrying seat 53 connected to the first moving seat 52. The first guiding chute 54 is arranged on the first moving seat 52, the first guiding slide rail 41 is arranged on the material conveying truss 4, and the first driving motor 51 drives the first moving seat 52 to reciprocate on the material conveying truss 4.

[0054] The first driving motor 51 provides a power source for the feeding mechanism 5. The first moving seat 52 reciprocates along the material conveying truss 4 under the cooperation of the first guiding chute 54 and the first guiding slide rail 41, driving the pipe carrying seat 53 carrying the pipe 9 to move synchronously, realizing the transfer of the pipe 9 between the feeding end 21 and the chamfering mechanism 6. As a preferred example under this embodiment, the first moving seat 52 includes a first horizontal plate and a first vertical plate. The first guiding chute 54 is arranged on the first vertical plate, the first guiding slide rail 41 is arranged on the side of the material conveying truss 4, the output shaft of the first driving motor 51 passes through the first horizontal plate and is provided with a rotating gear at the end, and a rack adapted to the rotating gear is arranged on the top of the material conveying truss 4. When the first driving motor 51 works, its output shaft drives the rotating gear to rotate, and drives the first moving seat 52 to move through the meshing cooperation between the rotating gear and the rack.

[0055] As a preferred example under this embodiment, as Figure 4 shown, the feeding mechanism 5 further includes a pneumatic push rod 55 arranged on the pipe carrying seat 53, and the pneumatic push rod 55 can push the pipe 9 in the direction of the fixing member 61. When the feeding mechanism 5 moves to a position close to the chamfering mechanism 6 under the action of the first driving motor 51, the pneumatic push rod 55 can push the pipe 9 on the pipe carrying seat 53, push the pipe 9 from the pipe carrying seat 53 to the fixing member 61, and fix the pipe 9 through the fixing member 61, realizing the clamping and fixing of the pipe 9, reducing the transfer difficulty of the pipe 9 from the pipe carrying seat 53 to the fixing member 61, and helping to improve the feeding efficiency of the feeding mechanism 5 to the chamfering mechanism 6.

[0056] As a preferred embodiment of the present application, asFigure 1 , Figure 3 As shown, one of the unloading mechanism 7 and the material conveying gantry 4 is provided with a second guiding slide rail 42, and the other is provided with a second guiding chute 74 adapted to the second guiding slide rail 42. The unloading mechanism 7 realizes reciprocating movement between the chamfering mechanism 6 and the unloading end 22 through the sliding fit of the second guiding slide rail 42 and the second guiding chute 74.

[0057] By providing the second guiding slide rail 42 and the second guiding chute 74, the unloading mechanism 7 can realize reciprocating movement along the material conveying gantry 4 through their sliding fit, reducing the frictional resistance suffered by the unloading mechanism 7 during movement, thereby realizing rapid reciprocating movement between the unloading end 22 and the chamfering mechanism 6 and improving the unloading efficiency. In addition, by providing the second guiding slide rail 42 and the second guiding chute 74, the movement direction of the unloading mechanism 7 can be restricted, preventing the unloading mechanism 7 from deviating during movement, ensuring that the unloading mechanism 7 can accurately pick up the pipe 9 from the fixing member 61 and convey it to the unloading end 22, and improving the conveying accuracy of the pipe 9 by the unloading mechanism 7.

[0058] As a preferred embodiment under this preferred implementation manner, as Figure 4 shown, the unloading mechanism 7 includes a second driving motor 71, a second moving seat 72, and a tensioning and fixing member 73 connected to the second moving seat 72. The second guiding chute 74 is provided on the second moving seat 72, the second guiding slide rail 42 is provided on the material conveying gantry 4, the tensioning and fixing member 73 includes a plurality of tensioning plates 731, and the tensioning plates 731 are in contact with the inner wall of the pipe 9 and fix the pipe 9 to the tensioning and fixing member 73 through friction.

[0059] The second driving motor 71 provides a power source for the unloading mechanism 7, and the second moving seat 72 reciprocates along the material transport frame 4 under the cooperation of the second guide slide groove 74 and the second guide slide rail 42, driving the tensioning and fixing parts 73 carrying the pipe 9 to move synchronously, thereby realizing the transfer of the pipe 9 from the chamfering mechanism 6 to the unloading end 22; and by providing a tensioning and fixing part 73 including a plurality of tensioning plates 731, when the unloading mechanism 7 receives the pipe 9, it only needs to insert the tensioning plate 731 into the pipe 9, and then control the tensioning plate 731 to expand outward until it is against the inner wall of the pipe 9 to fix the pipe 9. In the process of fixing the pipe 9, there is no need to occupy the external space of the pipe 9, thereby reducing the probability of interference between the tensioning and fixing parts 73 and other components during the transfer of the pipe 9 from the chamfering mechanism 6 to the unloading end 22, which helps to improve the smoothness of the transfer of the pipe 9. As a preferred example under the embodiment, the second movable seat 72 includes a second horizontal plate and a second vertical plate, the second guide slide groove 74 is arranged on the second vertical plate, the second guide slide rail 42 is arranged on the side of the material transport frame 4, the output shaft of the second drive motor 71 is passed through the second horizontal plate and is provided with a rotating gear at the end, and the top of the material transport frame 4 is provided with a rack adapted to the rotating gear. When the second drive motor 71 is working, its output shaft drives the rotating gear to rotate, and drives the second movable seat 72 to move through the meshing cooperation of the rotating gear and the rack.

[0060] As a preferred example under this embodiment, Figure 4 As shown, the tensioning fixture 73 is connected to the second movable seat 72 via a rotating member, and the rotating member includes a rotating gear 8. The tensioning fixture 73 is connected to the output shaft of the rotating gear 8 and turns synchronously with the rotation of the rotating gear 8. In this way, when the tensioning fixture 73 transports the pipe 9 to the discharge end 22, the rotating gear 8 rotates, so that the tensioning fixture 73 rotates synchronously with the rotating gear 8, and drives the pipe 9 to rotate synchronously, thereby adjusting the pipe 9 to a direction that is easier to discharge, reducing the difficulty of discharging the pipe 9. This example does not limit the rotation angle and rotation direction of the rotating gear 8. In a preferred embodiment, the pipe 9 is initially transported to the discharge end 22 in a horizontal direction, and the rotating gear 8 rotates 90°, and the pipe 9 then turns 90° to a vertical state.
