Description

Technical Field

[0001] The present invention relates to the technical field of steel pipe processing equipment, and in particular to a short pipe processing production line. Background Art

[0002] At present, in the machinery manufacturing industry, the demand for steel pipes of various length specifications is increasing day by day. Especially in some precision instruments and mechanical equipment, the demand for short pipes (i.e., pipes with a length less than 500 mm) is particularly obvious.

[0003] When producing and processing short pipes, usually a long steel pipe is cut into short pipes of a fixed length by a cutting device. Then, an operator takes and places the cut short pipes onto a chamfering station, and chamfers both ends of the short pipes through a chamfering device. After the chamfering process is completed, the operator takes and places the short pipes onto a chip removal station, and removes the iron chips generated inside the short pipes due to the chamfering process through a chip removal device. After the chip removal is completed, the operator takes and places the short pipes onto a degreasing station, and removes the oil stains at both ends of the short pipes through a degreasing device.

[0004] In the existing production and processing process of short pipes, since the transfer and placement process of short pipes between different processing procedures requires the participation of operators, the efficiency of the transfer and placement of short pipes between different processing procedures is affected by the operators, and further affects the production and processing efficiency of short pipes. Summary of the Invention

The other side of the conveyor 1 is provided with a material transfer mechanism. One side of the buffer device away from the conveyor 1 is provided with an intermittent conveyor. On both sides of the intermittent conveyor, a chamfering device and a preliminary cleaning device are arranged in sequence along the conveying direction. One side of the intermittent conveyor away from the buffer device is provided with a conveyor 2. One side of the conveyor 2 is provided with a mounting frame.

A secondary cleaning device and a length measuring device are arranged on the mounting frame in sequence along the feeding direction. A receiving device is arranged at one end of the mounting frame.

[0007] By adopting the above technical solution, the use of conveyor 1 in cooperation with the material transfer mechanism helps to convey and place the cut and formed short tubes into the buffer device for temporary storage; the use of the intermittent conveyor device helps to intermittently convey the short tubes stored on the buffer device to the processing positions of the chamfering device and the preliminary cleaning device for chamfering and preliminary cleaning in sequence; the use of conveyor 2 in cooperation with the transfer assembly helps to transfer and place the short tubes after chamfering and preliminary cleaning onto the feeding assembly of the mounting rack, and the use of the feeding assembly helps to intermittently convey the short tubes to the processing positions of the secondary cleaning device and the length measuring device for secondary cleaning and length measurement in sequence, and the use of the receiving device helps to separately collect and store the short tubes with qualified and unqualified length measurements; this application helps to realize the automatic transfer of short tubes between different processing procedures, thereby helping to improve the transfer efficiency of short tubes between different processing procedures, and further helping to improve the production and processing efficiency of short tubes.

The top material mechanism is used to lift the short tubes at the bottom end of the buffer rack 1 onto the buffer rack 2 in cooperation with the intermittent conveyor device.

[0009] By adopting the above technical solution, the use of buffer rack 1 and buffer rack 2 helps to store the short tubes in zones, and the use of the top material mechanism in cooperation with the intermittent conveyor device helps to lift and transfer the short tubes at the bottom end of the buffer rack 1 onto the buffer rack 2, thereby helping to automatically convey the short tubes at the bottom end of the buffer rack 2 to the processing positions of the chamfering device and the preliminary cleaning device for chamfering and preliminary cleaning by using the intermittent conveyor device.

[0011] By adopting the above technical solution, the double-headed motor helps drive the two rotating plates to rotate, thereby helping drive the connecting column body to move along the track of the activity track, and further helping drive the installation block to move synchronously through the installation rod. At the same time, the sliding of the movable block in the guide rail and the sliding of the slider on the slide rail help guide the moving track of the installation block, so as to help the installation block drive the material transporting plate to reciprocate according to the shape track of the activity track, and further help the material transporting plate automatically transport the short pipes at the bottom end of the buffer rack two to a group of feeding grooves close to the fixed rack during the movement, and at the same time transfer the short pipes placed in each group of feeding grooves to the next group of feeding grooves until the short pipes in the last group of feeding grooves are transferred to the conveyor two for transportation.

[0041] Reference Figure 1 and Figure 2In the production process of short tubes, the long tube is cut into short tubes of set length by the cutting device 1, and the cut short tubes are transported by the conveyor 2. At the same time, the drive motor 49 is running, and the output end of the drive motor 49 drives the screw 50 to rotate, thereby driving the lifting block 48 to slide down in the vertical groove 47, and then driving the material moving baffle 52 located above the conveyor 2 to gradually descend through the mounting plate 51 until it is close to the surface of the conveyor 2.

[0042] Reference Figure 2 and Figure 3 , the driving cylinder 532 operates, the piston rod of the driving cylinder 532 extends, driving the plug-in column 533 and the grabbing clamp 534 to pass through the clearance opening 55, and under the guidance of the guide part 54, the plug-in column 533 is gradually inserted into the interior of the short tube, and the grabbing clamp 534 cooperates with the plug-in column 533 to clamp the short tube, thereby achieving the grabbing of the short tube.

[0043] Reference Figure 2 and Figure 3 After grabbing the short tube, the driving motor 49 runs in the reverse direction, so that the lifting block 48 rises in the vertical slot 47, thereby driving the grabbed short tube to move upward through the mounting plate 51 and the material shifting baffle 52. At the same time, the linear slide 45 runs, driving the vertical rod 46 to move horizontally toward the conveyor 2, thereby driving the material shifting baffle 52 to move synchronously through the lifting block 48 and the mounting plate 51, until the material shifting baffle 52 moves to the top of the buffer rack 12. Afterwards, the driving cylinder 532 runs in the reverse direction, and the piston rod of the driving cylinder 532 contracts, driving the plug-in column 533 and the material grabbing clamp 534 to pass through the clearance opening 55 in the reverse direction, so that the grabbed short tube falls onto the buffer device.

[0044] Reference Figure 1 and Figure 2 , the linear slide 45 runs in the reverse direction, driving the vertical rod 46 to move horizontally in the direction away from the conveyor 2, thereby driving the material transfer baffle 52 to move synchronously through the lifting block 48 and the mounting plate 51, until the material transfer baffle 52 moves to the top of the conveyor 2. Such a reciprocating cycle helps to grab the short tubes transported on the conveyor 2 and place them on the buffer device for temporary storage.

[0045] Reference Figure 1 and Figure 4 An intermittent conveying device is fixed on one side of the buffer device away from the conveyor 2, and a chamfering device 3 and a preliminary cleaning device 4 are fixedly installed in sequence on both sides of the intermittent conveying device along the conveying direction.

[0046] Reference Figure 4 and Figure 5, the intermittent conveying device includes a blanking rack 15 distributed adjacent to the buffer device. A plurality of groups of blanking grooves 16 are spaced apart on the top of the blanking rack 15. A groove rack 17 is fixed inside the blanking rack 15.

A connecting rod 42 is fixedly installed between the two material conveying plates 23. A plurality of groups of material clamping grooves 24 are spaced apart on the top of the two material conveying plates 23.

[0047] Refer to Figure 5 , a mounting rod 25 is fixedly connected to the bottom of the mounting block 22. A connecting cylinder 26 is coaxially fixedly connected to the end of the mounting rod 25 away from the mounting block 22. A double-headed motor 27 is fixedly installed inside the groove rack 17. Each output end of the double-headed motor 27 penetrates through a side wall of the groove rack 17 and extends out of the groove rack 17. A rotating plate 28 is fixedly connected to each output end of the double-headed motor 27. A waist-shaped hole 29 is penetrated through the rotating plate 28. A movable track 30 is opened on the outer wall of the groove rack 17. The connecting cylinder 26 passes through the waist-shaped hole 29 and is inserted into the movable track 30.

[0048] Refer to Figure 5 , when the double-headed motor 27 is started, the two output ends of the double-headed motor 27 drive the two rotating plates 28 to rotate, thereby driving the mounting block 22 to move through the connecting cylinder 26 and the mounting rod 25; while the mounting block 22 is moving, the sliding of the slider 21 on the slide rail 20 and the sliding of the movable block 19 in the guide rail 18 help to guide and limit the movement track of the mounting block 22, thereby helping the mounting block 22 to drive the material conveying plate 23 to reciprocate according to the shape track of the movable track 30.

[0049] Refer to Figure 4 and Figure 6, a blanking mechanism is arranged inside the fixing frame 11. The blanking mechanism includes a moving block 31 and two columns 32 fixedly arranged inside the fixing frame 11 at intervals. An arc-shaped concave surface 34 is formed on the top surface of the moving block 31. Two long strip holes 33 are formed through the moving block 31 at intervals on both sides of the arc-shaped concave surface 34. Each column 32 passes through a long strip hole 33, and the side wall of each column 32 abuts against the side of the long strip hole 33 far away from the blanking rack 15. A top plate 35 is jointly installed at the top ends of the columns 32. A vertically arranged lifting rod 36 is slidably installed on the top plate 35.

The bottom end of the return spring 39 is fixedly connected with the bottom plate 37, and the top end of the return spring 39 is fixedly connected with the top plate 35. A slantingly arranged blanking plate 40 is fixedly installed at the top end of the lifting rod 36. The blanking plate 40 is located below the bottom end of the first buffer rack 12. The top surface height of the blanking plate 40 gradually decreases along the direction from the first buffer rack 12 towards the second buffer rack 13.

[0050] Refer to Figure 6 , a connecting component 41 is arranged on the moving block 31. The connecting component 41 includes a connecting rod 411, a connecting block 412, a transmission rod 413 and a transmission column 414. One end of the connecting rod 411 is fixedly connected with the moving block 31. The connecting block 412 is fixedly installed at the end of the connecting rod 411 far away from the moving block 31. One end of the transmission rod 413 is fixedly connected with the connecting rod 42. The transmission column 414 is fixedly installed at the end of the transmission rod 413 far away from the connecting rod 42. A clamping groove 43 is formed through the connecting block 412. The transmission column 414 can be lifted and clamped inside the clamping groove 43.

[0051] Refer to Figure 4 , Figure 5 and Figure 6 , when the two material transporting plates 23 move, they drive the connecting rod 42 and the transmission rod 413 to move synchronously, so as to drive the connecting rod 411 and the moving block 31 to horizontally move in the direction away from the blanking rack 15 through the movable connection between the transmission column 414 and the connecting block 412. Furthermore, the roller 38 rolls from a low position to a high position on the arc-shaped concave surface 34. During the rolling process, the lifting rod 36 and the blanking plate 40 are driven to rise, which helps to lift and transfer the short pipes at the bottom end of the first buffer rack 12 to the second buffer rack 13 through the slantingly arranged blanking plate 40. The short pipes roll towards the low position on the second buffer rack 13 and are blocked by the two baffle blocks 14 at the bottom end position of the second buffer rack 13, so as to be temporarily stored at the bottom end of the second buffer rack 13.

[0052] Refer to Figure 4 and Figure 5, during the reciprocating movement of the two material transporting plates 23, the two material transporting plates 23 will drive the short pipes at the bottom end of the second buffer rack 13 to move synchronously for a certain distance through the material clamping grooves 24 until the short pipes are placed into a group of material placing grooves 16 at the top of the material discharging rack 15; at the same time, the two material transporting plates 23 will transfer the short pipes placed in a group of material placing grooves 16 to the next group of material placing grooves 16 for placement.

[0053] Referring to Figure 1 and Figure 4 , when the short pipes are successively placed into a group of material placing grooves 16 located between the chamfering devices 3 and a group of material placing grooves 16 located between the preliminary cleaning devices 4, the chamfering devices 3 and the preliminary cleaning devices 4 will successively chamfer and preliminarily clean the short pipes.

[0054] Referring to Figure 1 , on the side of the intermittent conveying device far from the buffer device, a second conveyor 5 is fixedly installed. On one side of the end of the second conveyor 5 far from the intermittent conveying device, a mounting frame 6 is fixed. A feeding assembly 7 is arranged on the mounting frame 6. On both sides of the feeding assembly 7 on the mounting frame 6, a secondary cleaning device 9 and a length measuring device 10 are successively installed along the feeding direction. A receiving device is installed at the end of the mounting frame 6 far from the second conveyor 5. A transfer assembly 8 is arranged on the side of the second conveyor 5 facing away from the mounting frame 6.

[0055] Referring to Figure 7 , the transfer assembly 8 includes a mounting post 81, a linear module 82, a rotary cylinder 83 and a transfer gripper 84. The mounting post 81 is fixedly installed on the side of the second conveyor 5 facing away from the mounting frame 6. The linear module 82 is vertically and fixedly installed on the side wall of the mounting post 81 facing the second conveyor 5. The rotary cylinder 83 is fixedly installed on the movable end of the linear module 82. The transfer gripper 84 is fixedly installed on the output end of the rotary cylinder 83.

[0056] Referring to Figure 8 , the feeding assembly 7 includes a stepping motor 71, a driving gear 72, a driven gear 73, a feeding chain 74 and a plurality of material placing plates 75. In this embodiment, the number of the driving gear 72, the driven gear 73 and the feeding chain 74 is two. The stepping motor 71 is fixedly installed on the outer side wall of the mounting frame 6. The two driving gears 72 are spaced and fixed on the output shaft of the stepping motor 71, and each driving gear 72 is close to the inner side wall of one side of the mounting frame 6. The two driven gears 73 are rotatably installed on the opposite inner side walls of the mounting frame 6, and the driven gears 73 are located at the end of the mounting frame 6 far from the driving gear 72. Each feeding chain 74 is sleeved around the driving gear 72 and the driven gear 73. The plurality of material placing plates 75 are spaced and installed on the feeding chain 74.

[0057] Referring to Figure 1 , Figure 7 and Figure 8, after the initial cleaning of the short pipe is completed, the short pipe is transferred to the conveyor two 5 for transportation. When the short pipe is transported to the end of the conveyor two 5, it will be blocked and stopped. The linear module 82 is activated, driving the rotary cylinder 83 and the transfer gripper 84 to descend synchronously until the transfer gripper 84 descends to the clamping position. Then, the transfer gripper 84 is activated to clamp the short pipe on the conveyor two 5; the linear module 82 rotates in the reverse direction, driving the rotary cylinder 83 and the transfer gripper 84 to rise synchronously. At the same time, the rotary cylinder 83 is activated, driving the transfer gripper 84 and the clamped short pipe to rotate 90 degrees; then, the linear module 82 rotates in the forward direction, driving the rotary cylinder 83 and the transfer gripper 84 to descend synchronously, so as to place the short pipe on a set of discharge plates 75 on the feeding chain 74.

[0058] Referring to Figure 8 , after the short pipe is placed on the discharge plate 75, the stepping motor 71 operates, driving the two driving gears 72 to rotate intermittently synchronously, which helps the two feeding chains 74 to rotate intermittently with the cooperation of the two driven gears 73, and helps to drive the short pipe on the discharge plate 75 to move intermittently to the processing positions of the secondary cleaning device 9 and the length measuring device 10, so as to help the secondary cleaning device 9 and the length measuring device 10 to perform secondary cleaning and length measurement on the short pipe in sequence.

[0059] Referring to Figure 1 and Figure 8 , the receiving device includes a receiving frame 56 fixedly installed at one end of the mounting frame 6 away from the conveyor two 5. The top of the receiving frame 56 is fixedly installed with a first discharge frame 57. The top of the first discharge frame 57 is detachably installed with a second discharge frame 58, and the distance between the side of the second discharge frame 58 close to the mounting frame 6 and the mounting frame 6 is greater than the distance between the side of the first discharge frame 57 close to the mounting frame 6 and the mounting frame 6. Two spaced-apart discharge plates 59 are rotatably installed on the side wall of the mounting frame 6 close to the receiving frame 56. Two spaced-apart top support cylinders 60 are fixedly installed on the mounting frame 6 below the discharge plates 59. The piston rod of each top support cylinder 60 is hinged to the discharge plate 59, and the top support cylinder 60 is electrically connected to the length measuring device 10.

[0060] Referring to Figure 8When the length measuring device 10 detects that the length of the short tube is qualified, the short tube rolls down to the unloading plate 59 under the cooperation of the feeding chain 74 and the unloading plate 75. At this time, the bottom end of the unloading plate 59 is located above the second unloading frame 58, so that the short tube rolls down along the unloading plate 59 to the second unloading frame 58 for storage. When the length measuring device 10 detects that the length of the short tube is unqualified, the short tube rolls down to the unloading plate 59 under the cooperation of the feeding chain 74 and the unloading plate 75. At the same time, the length measuring device 10 transmits a signal to the supporting cylinder 60, and the piston rod of the supporting cylinder 60 contracts, driving the unloading plate 59 to rotate, so that the bottom end of the unloading plate 59 rotates to the top of the first unloading frame 57, so that the short tube rolls down along the unloading plate 59 to the first unloading frame 57 for storage.

[0061] The implementation principle of the embodiment of the present application is as follows: in the production and processing of short tubes, the long tube is cut into short tubes of a set length by the cutting device 1, and the cut short tubes are transported by the conveyor 2. At the same time, the driving motor 49 is running, and the output end of the driving motor 49 drives the screw 50 to rotate, thereby driving the lifting block 48 to slide down in the vertical slot 47, and then driving the material moving baffle 52 located above the conveyor 2 to gradually descend through the mounting plate 51 until it is close to the surface of the conveyor 2. Afterwards, the driving cylinder 532 is running, and the piston rod of the driving cylinder 532 is extended, driving the plug-in column 533 and the material grabbing clamp 534 to pass through the clearance opening 55, and under the guidance of the guide part 54, the plug-in column 533 is gradually inserted into the interior of the short tube, and the material grabbing clamp 534 cooperates with the plug-in column 533 to clamp the short tube, so as to achieve the grabbing of the short tube.

[0062] After grabbing the short tube, the driving motor 49 runs in the reverse direction, so that the lifting block 48 rises in the vertical slot 47, thereby driving the grabbed short tube to move upward through the mounting plate 51 and the material shifting baffle 52. At the same time, the linear slide 45 runs, driving the vertical rod 46 to move horizontally toward the direction of the conveyor 2, thereby driving the material shifting baffle 52 to move synchronously through the lifting block 48 and the mounting plate 51, until the material shifting baffle 52 moves to the top of the buffer rack 12. Afterwards, the driving cylinder 532 runs in the reverse direction, and the piston rod of the driving cylinder 532 contracts, driving the plug-in column 533 and the material grabbing clamp 534 to pass through the clearance opening 55 in the reverse direction, so that the grabbed short tube falls to the top of the buffer rack 12 and rolls to the bottom of the buffer rack 12 for temporary storage.

[0063] The linear slide 45 rotates in the reverse direction, driving the vertical rod 46 to move horizontally in the direction away from the conveyor 2, thereby driving the material transfer baffle 52 to move synchronously through the lifting block 48 and the mounting plate 51 until the material transfer baffle 52 moves to the top of the conveyor 2. Such a reciprocating cycle helps to grab the short tubes transported on the conveyor 2 and place them on the buffer rack 12 for temporary storage.

[0064] The dual-head motor 27 starts, and the two output ends of the dual-head motor 27 drive the two rotating plates 28 to rotate, thereby driving the mounting block 22 to move through the connecting column 26 and the mounting rod 25; while the mounting block 22 is moving, the sliding of the slider 21 on the slide rail 20 and the sliding of the movable block 19 in the guide rail 18 help to guide and limit the moving track of the mounting block 22, thereby helping the mounting block 22 to drive the material transporting plate 23 to reciprocate according to the shape track of the movable track 30.

[0065] When the two material transporting plates 23 move, they drive the connecting rod 42 and the transmission rod 413 to move synchronously, thereby driving the connecting rod 411 and the moving block 31 to move horizontally away from the feeding rack 15 through the movable connection between the transmission column 414 and the connecting block 412, and further causing the roller 38 to roll from the low position to the high position on the arc-shaped concave surface 34. During the rolling process, the lifting rod 36 and the blanking plate 40 are driven to rise, thereby helping to lift and transfer the short pipe at the bottom end of the buffer rack one 12 to the buffer rack two 13 through the inclined blanking plate 40. The short pipe rolls downward on the buffer rack two 13 and is blocked by the two material blocking blocks 14 at the bottom end position of the buffer rack two 13, so as to be temporarily stored at the bottom end of the buffer rack two 13.

[0066] During the reciprocating movement of the two material transporting plates 23, the two material transporting plates 23 will drive the short pipe at the bottom end of the buffer rack two 13 to move synchronously for a certain distance through the material clamping groove 24 until the short pipe is placed into a set of material placing grooves 16 at the top of the feeding rack 15; at the same time, the two material transporting plates 23 will transfer the short pipe placed in a set of material placing grooves 16 to the next set of material placing grooves 16 for placement. When the short pipes are successively placed into a set of material placing grooves 16 between the chamfering device 3 and a set of material placing grooves 16 between the preliminary cleaning device 4, the chamfering device 3 and the preliminary cleaning device 4 will successively perform chamfering processing and preliminary cleaning on the short pipes.

[0067] After the short pipe is preliminarily cleaned, the moving material transporting plate 23 transfers the short pipe to the conveyor two 5 for conveying. When the short pipe is conveyed to the end of the conveyor two 5, it will be blocked and stopped. The linear module 82 starts, driving the rotating cylinder 83 and the transfer gripper 84 to descend synchronously until the transfer gripper 84 descends to the clamping position. Then, the transfer gripper 84 starts to clamp the short pipe on the conveyor two 5; the linear module 82 runs in the reverse direction, driving the rotating cylinder 83 and the transfer gripper 84 to rise synchronously, and at the same time the rotating cylinder 83 starts, driving the transfer gripper 84 and the clamped short pipe to rotate 90 degrees; then, the linear module 82 runs in the forward direction, driving the rotating cylinder 83 and the transfer gripper 84 to descend synchronously, thereby placing the short pipe on a set of material placing plates 75 on the feeding chain 74.

[0068] After the short pipe is placed on the feeding plate 75, the stepping motor 71 operates to drive the two driving gears 72 to rotate synchronously and intermittently, which helps the two feeding chains 74 to rotate intermittently under the cooperation of the two driven gears 73, and helps to drive the short pipe on the feeding plate 75 to move intermittently to the processing positions of the secondary cleaning device 9 and the length measuring device 10, so as to help the secondary cleaning device 9 and the length measuring device 10 to perform secondary cleaning and length measurement on the short pipe in sequence.

[0069] When the length measuring device 10 detects that the length of the short pipe is qualified, the short pipe rolls onto the blanking plate 59 under the combined action of the feeding chain 74 and the feeding plate 75. At this time, the bottom end of the blanking plate 59 is located above the second blanking frame 58, so that the short pipe rolls along the blanking plate 59 into the second blanking frame 58 for storage. When the length measuring device 10 detects that the length of the short pipe is unqualified, the short pipe rolls onto the blanking plate 59 under the combined action of the feeding chain 74 and the feeding plate 75. At the same time, the length measuring device 10 transmits a signal to the top support cylinder 60, and the piston rod of the top support cylinder 60 contracts to drive the blanking plate 59 to rotate, so that the bottom end of the blanking plate 59 rotates above the first blanking frame 57, so that the short pipe rolls along the blanking plate 59 into the first blanking frame 57 for storage.

[0070] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of this application should be covered within the protection scope of this application.
