[0038] In order to make the technical problems to be solved by the present application, technical solutions and beneficial effects more clearly understood, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0039] It should be noted that the lead pipe is a blank before being punched, and the specific structures of the lead pipe after being punched, after being bottomed, after being turned, and after being rolled are all different. However, in order to facilitate description, the lead pipes in different forms are collectively referred to as lead pipes, and it can be understood that although they are called lead pipes, the specific forms of the lead pipes are different in different processes, which are different from the finally processed lead pipes.

[0040] Please refer to Figures 1 to 10The application provides a lead pipe automatic production equipment. The lead pipe automatic production equipment comprises a production line, a conveying mechanism located at one side of the production line, a feeding rack 70 located at a feeding end of the conveying mechanism, and a mechanical arm 80 located between the feeding rack 70 and the conveying mechanism. The production line comprises a punching station 10, a bottom cutting station 20, a turning station 30 and a rolling station 40 arranged in sequence along a first horizontal direction. The conveying mechanism comprises a conveying belt 50 parallel to the first horizontal direction and a first clamping jaw mechanism 60 slidingly connected to the conveying belt 50. The first clamping jaw mechanism 60 has a clamping part with a reciprocating movement freedom along a second horizontal direction, and the clamping part is used for clamping a lead pipe to move between adjacent stations. The second horizontal direction is perpendicular to the first horizontal direction. The feeding rack 70 is used for supporting a tray. The mechanical arm 80 is provided with a second clamping jaw mechanism 61 used for clamping a lead pipe and placing the lead pipe into the punching station 10.

[0041] The feeding rack 70 comprises a feeding position, a clamping position and a tray position. The feeding position and the tray position are located on two sides adjacent to the clamping position. The feeding position comprises a first conveying chain 71, a first clamping mechanism and a first push plate 73. The feeding end of the first conveying chain 71 is connected to the clamping position. The first clamping mechanism comprises two first clamping block assemblies 72 located on opposite sides of the first conveying chain 71. The first push plate 73 is used for pushing the tray on the first conveying chain 71 to the clamping position. The clamping position comprises a fixed seat 74, a first linear module 75 penetrating through the fixed seat 74 and extending below the tray position, and a second push plate 76 slidingly connected to the first linear module 75. The second push plate 76 is used for pushing the tray on the fixed seat 74 to the tray position. The tray position comprises a second conveying chain 77 and a second clamping mechanism. The feeding end of the second conveying chain 77 is connected to the clamping position. The second clamping mechanism comprises two second clamping block assemblies 78 located on opposite sides of the second conveying chain 77.

[0042] It is easy to understand that the first conveying chain 71 and the second conveying chain 77 need to adjust the position of the tray, and therefore the first conveying chain 71 and the second conveying chain 77 are respectively started and stopped by a motor control.

[0043] The first linear module 75 is parallel to the second conveying chain 77. Similarly, the first push plate 73 can also be driven by a second linear module 79 to reciprocate along the extension path of the first conveying chain 71, so as to push the lowermost tray in the whole stack of trays to the fixed seat 74.

[0044] The lead pipe automatic production equipment provided by the embodiment arranges the stamping station 10, the bottom cutting station 20, the turning station 30 and the rolling station 40 in sequence. Before production, a stack of trays is placed on the first conveying chain 71. The first conveying chain 71 moves the position of the stack of trays, so that the position of the tray is close to the fixed seat 74. At the beginning, the first clamping mechanism clamps the second tray from bottom to top. The first push plate 73 moves to push the lowermost tray to the fixed seat 74. The first clamping mechanism releases the tray and automatically descends. The tray on the fixed seat 74 has a plurality of hole positions for accommodating lead pipe blanks. The mechanical arm 80 grabs at least one each time. After grabbing is completed, the second push plate 76 moves to push the tray on the fixed seat 74 to the second conveying chain 77. When the second push plate 76 moves next time, the second clamping mechanism works to lift the tray to put the tray from the bottom of the lifted tray. The mechanical arm 80 puts the blank into the stamping station 10 after grabbing the blank. After the stamping station 10 is stamped, the first clamping jaw mechanism 60 grabs out. Then the first clamping jaw mechanism 60 puts the stamped lead pipe into the bottom cutting station 20. The bottom cutting station 20 is taken out and put into the turning station 30. The turning station 30 is taken out and put into the rolling station 40. After the above process, the lead pipe production is completed.

[0045] Compared with the prior art, the lead pipe automatic production equipment arranges the various processing stations in sequence and moves the lead pipe between the various stations through the first clamping jaw mechanism 60 on the conveying belt 50, realizes the processing process of the lead pipe, has high cooperation degree throughout the process and improves production efficiency. The feeding of the stamping station 10 is realized through the feeding rack 70 and the mechanical arm 80. The feeding position, the clamping position and the tray position on the feeding rack 70 can automatically realize the movement of the tray, so that the feeding is uninterrupted, the feeding time is shortened, manual operation is replaced, safety is higher and the labor intensity of workers is reduced.

[0046] In some embodiments, one specific implementation of the first clamping block assembly 72 and the second clamping block assembly 78 described above can adopt the structure as shown in Figures 8 to 9 . Referring to Figures 8 to 9 , the first clamping block assembly 72 and the second clamping block assembly 78 both include the first cylinder 721 with the piston rod arranged upwards, the first fixed plate 722 fixedly connected to the piston rod of the first cylinder 721, the first sliding rail 723 fixedly connected to the first fixed plate 722, the sliding plate 724 slidingly connected to the first sliding rail 723, the second cylinder 725 arranged on the first fixed plate 722, the piston rod of the second cylinder 725 being parallel to the first sliding rail 723 and being fixedly connected to the sliding plate 724. The first sliding rail 723 in the first clamping block assembly 72 is perpendicular to the first conveying chain 71. The first sliding rail 723 in the second clamping block assembly 78 is perpendicular to the second conveying chain 77.

[0047] Take the action process of the first clamp block assembly 72 as an example: the movement of the piston rod of the first cylinder 721 can drive the sliding plate 724 to adjust the height to be consistent with the height of the tray to be clamped, and after the height adjustment is completed, the second cylinder 725 is started, and the second cylinder 725 drives the sliding plate 724 to move close to the tray, so that the sliding plates 724 in the two first clamp block assemblies 72 can cooperate to clamp the tray. At this time, the first push plate 73 can be moved to push the lowermost tray towards the position of the fixed seat 74, and after the pushing is completed, the first cylinder 721 drives the first fixed plate 722 to descend, so as to control the whole stack of trays to sink and be placed on the first conveying chain 71 again. The action process of the second clamp block assembly 78 is the same. Through the above structure, it is convenient to switch the tray between the feeding position, the clamping position and the tray position. The clamping position is within the space range that the mechanical arm 80 can operate, and it is convenient for the mechanical arm 80 to take the blank from the tray in the clamping position.

[0048] In specific use, in order to facilitate the adjustment of the height of the first conveying chain 71 and the second conveying chain 77, a lifting cylinder 710 can also be configured on the first conveying chain 71 and the second conveying chain 77 respectively.

[0049] In order to avoid the second push plate 76 from pushing the tray down the second conveying chain 77 when working, two blocking rods can also be fixed at the discharge end of the second conveying chain 77; and in order to adapt to the accumulation of trays one by one, a lifting cylinder 710 can also be configured on the blocking rod 711, which drives the blocking rod 711 to move up and down to ensure that the top end of the blocking rod 711 is higher than the height of the uppermost tray.

[0050] In some embodiments, one specific implementation of the above fixed seat 74 can adopt the structure as shown in Figures 8 to 9 . Referring to Figures 8 to 9The fixed base 74 includes two third cylinders 741 spaced apart along the extension path of the first conveyor chain 71, and two support plates 742 located between the two third cylinders 741. The piston rods of the third cylinders 741 are arranged upwards. A baffle 743 is fixedly connected to the piston rod of each third cylinder 741. The surface of the baffle 743 is perpendicular to the extension path of the first conveyor chain 71. The two support plates 742 are spaced apart to form a through slot for the first linear module 75 to pass through. The top of each support plate 742 is equipped with an array of ball bearings 744. When the first push plate 73 moves, the third cylinder 741 drives the baffle 743 to descend, which helps the pallet smoothly enter above the two support plates 742. The ball bearings 744 on the support plates 742 can reduce the frictional resistance between the pallet and the support plates 742, improve the service life of the pallet, and ensure the smoothness of the pallet's movement. After the pallet is on the two support plates 742, the third cylinder 741 drives the baffle 743 to move upward. The two baffles 743 limit the pallet on opposite sides to prevent the pallet from shifting when the robotic arm 80 grabs the blank on the pallet, thus ensuring the accuracy of the robotic arm 80 when grabbing the material.

[0051] In some embodiments, a specific implementation of the first gripper mechanism 60 and the second gripper mechanism 61 may adopt the following approach: Figures 6 to 7 The structure shown. See also Figures 6 to 7 The first gripper mechanism 60 and the second gripper mechanism 61 both include a base 62, a second slide rail 63 fixed on the base 62, two gripping arms 64 slidably connected to the second slide rail 63, and a double-headed cylinder 65 fixed to the base 62. The two piston rods of the double-headed cylinder 65 are respectively fixed to the two gripping arms 64, and the gripping part is located at the other end of the two gripping arms 64. The first gripper mechanism 60 also includes a movable seat 66 slidably connected to the conveyor belt 50, a fourth cylinder 67 fixed to the movable seat 66 with the piston rod facing upward, a top plate 68 fixed to the piston rod of the fourth cylinder 67, and a third linear module 69 fixed on the top plate 68. The third linear module 69 is parallel to the second horizontal direction, and the base 62 on the first gripper mechanism 60 is slidably engaged with the third linear module 69.

[0052] It should be noted that the top of the lead pipe has two outer rings, the outer diameter of which is larger than the outer diameter of the lead pipe. The two outer rings are spaced apart along the axis of the lead pipe. There are two ways to transport the lead pipe: one is to adjust the distance between the two clamping arms 64 to be equal to the outer diameter of the lead pipe. When the lead pipe needs to be clamped, the two clamping arms 64 extend into the space between the two outer rings, and then the clamping arms 64 are lifted. The clamping arms 64 can be supported on the bottom surface of the upper outer ring. When the lead pipe is lowered, they can be pulled out. The other method is to adjust the distance between the two clamping arms 64 through the double-headed cylinder 65. The two clamping arms 64 are opened and placed at the same height in the space between the two outer rings. Then, the two clamping arms 64 are driven to approach and clamp the steel pipe and are fixed by the positioning component. The process of lowering the lead pipe is the same.

[0053] Wherein the first jaw mechanism 60 needs to move on the conveying belt 50, by setting the moving seat 66 to cooperate with the conveying belt 50, and then driving the top plate 68 to move up and down by the fourth cylinder 67, the clamping part in the first jaw mechanism 60 can move up and down, so as to align with the working height on the punching station 10 or the bottom cutting station 20 or the turning station 30 or the rolling station 40, facilitate the taking and placing of the lead pipe on multiple works, ensure the machining precision, and improve the product quality.

[0054] In some embodiments, one specific implementation of the above-mentioned clamping part can adopt the structure as shown in Figure 7 . Referring to Figure 7 , the bottom of the end of each clamping arm 64 away from the double-headed cylinder is fixedly connected with a clamping piece 610, the side surface of the clamping piece 610 towards the clamping piece 610 in the other clamping arm 64 is recessed to form a V-shaped clamping groove 611, the clamping grooves 611 on the two clamping pieces 610 are symmetrical, and the bottom of each clamping piece 610 is further provided with an abutting plate 612, which is used to abut the outer peripheral surface of the larger diameter part of the lead pipe. The two clamping pieces 610 and the abutting plate 612 form the clamping part. In this embodiment, when the structure clamps the lead pipe, the inner wall of the clamping groove 611 can fit the outer peripheral surface of the lead pipe, and the abutting plate 612 fits the outer peripheral surface of the outer ring below, which can improve the stability of clamping the lead pipe and avoid the lead pipe from falling during the process of clamping and moving the lead pipe.

[0055] In some embodiments, one specific implementation of the above-mentioned bottom cutting station 20 can adopt the structure as shown in Figure 2 . Referring to Figure 2 , the bottom cutting station 20 includes a bottom cutting plate 21, a cutting knife 23 which is movable horizontally below the bottom cutting plate 21, and a first pressing cylinder 24 above the bottom cutting plate 21, and the bottom cutting plate 21 has a through hole 22 for placing the lead pipe. The first jaw mechanism 60 places the lead pipe in the through hole 22 of the bottom cutting plate 21, the first pressing cylinder 24 presses on the top of the lead pipe, the cutting knife 23 moves horizontally to cut off the bottom edge of the lead pipe, and the first jaw mechanism 60 takes down the lead pipe after the bottom cutting is completed.

[0056] In specific implementation, the punching station 10, the bottom cutting station 20, the turning station 30, and the rolling station 40 are all installed on the same fixed table, optionally, the cutting knife 23 can be fixed on the first sliding seat 25, the first sliding seat 25 is controlled to move by the cylinder or the linear module, and the rail 26 can be installed on the fixed table, the first sliding seat 25 and the rail 26 are in sliding cooperation, which improves the stability of the movement of the cutting knife 23 and improves the bottom cutting quality.

[0057] In some embodiments, one specific implementation of the above-mentioned turning station 30 can adopt the structure as shown in Figure 3 . Referring to Figure 3The turning station 30 includes a first rotary table 31, a cutting tool 32 located on one side of the first rotary table 31, and a second pressing cylinder 33 located above the first rotary table 31. The first gripper mechanism 60 places the lead pipe on the first rotary table 31, and the second pressing cylinder 33 moves downward to abut against the upper surface of the lead pipe. The first rotary table 31 drives the lead pipe to rotate. During the rotation of the lead pipe, the cutting tool 32 gradually feeds in, turning external threads on the outer circumference of the lead pipe. Then, the tool is retracted to remove the lead pipe.

[0058] In some embodiments, a specific implementation of the above-described rolling station 40 may employ, as follows: Figure 4 The structure shown. See also Figure 4 The rolling station 40 includes a second rotating seat 41, a rolling cutter 42 located on one side of the second rotating seat 41, and a third pressing cylinder 43 located above the second rotating seat 41. The first gripper mechanism 60 places the lead pipe on the second rotating seat 41, and the third pressing cylinder 43 moves downward to abut against the upper surface of the lead pipe. The second rotating seat 41 drives the lead pipe to rotate. During the rotation of the lead pipe, the rolling cutter 42 gradually feeds in, rolling the external threads on the outer circumference of the lead pipe. Then, the cutter retracts to remove the lead pipe.

[0059] It should be noted that, since the second pressing cylinder 33 or the third pressing cylinder 43 needs to abut against the upper surface of the lead pipe, and the lead pipe needs to rotate during the threading or rolling process, in order to avoid wear on the top surface of the lead pipe by the second pressing cylinder 33 or the third pressing cylinder 43, the piston rod end of the second pressing cylinder 33 and the third pressing cylinder 43 are equipped with a rotating head. Thus, when the lead pipe rotates, the rotating head rotates with the lead pipe, ensuring the processing dimensions of the lead pipe.

[0060] It is easy to imagine that the first rotating seat 31 is driven to rotate by a motor, and the first rotating seat 31 is provided with holes for placing lead pipes. The second rotating seat 41 is similar.

[0061] Specifically, during the processing of lead pipes, one lead pipe can be clamped and processed at a time, or multiple lead pipes can be clamped and processed at a time. When multiple lead pipes are clamped at a time, the cavities in the stamping station 10 are also provided in a corresponding manner. The number of through holes 22 and cutting blades 23 in the bottom cutting station 20 are also provided in a corresponding manner. The number of first rotary seats 31 and cutting tools 32 in the turning station 30 are also provided in a corresponding manner. The number of second rotary seats 41 and hobs 42 in the rolling station 40 are also provided in a corresponding manner.

[0062] When multiple lead pipes are processed at the same time, multiple tool bits 32 and multiple hobbing cutters 42 are needed, multiple tool bits 32 can be fixed on the second sliding seat 34 at the same time, multiple hobbing cutters 42 can be fixed on the third sliding seat 44 at the same time, the second sliding seat 34 and the third sliding seat 44 can slide on the fixed table top for adjustment (specifically, the movement can be driven by a pneumatic cylinder or a linear module), the second sliding seat 34 is provided with multiple small pneumatic cylinders, the number of small pneumatic cylinders is the same as the number of tool bits 32, and each tool bit 32 can be driven by a small pneumatic cylinder to move up and down, so as to adapt to the height of the lead pipe, and the third sliding seat 44 can also control each hobbing cutter 42 to move up and down through a small pneumatic cylinder.

[0063] In some embodiments, an improved embodiment of the above-mentioned lead pipe automatic production equipment can adopt the structure as shown in Figure 1 and Figure 10 . Referring to Figure 1 and Figure 10 , the lead pipe automatic production equipment further comprises a stacking station 90 located at the rolling station 40 process, the stacking station 90 comprises a stacking disc 91, a peripheral frame 92 fixed to the top of the stacking disc 91, a pushing cylinder 94 arranged outside the peripheral frame 92, an opening 93 is formed in the peripheral frame 92, and the piston rod of the pushing cylinder 94 is fixed with a pushing plate, and the pushing plate extends into the space in the inner circle of the peripheral frame 92 through the opening 93. After the lead pipe production is completed, the first clamping jaw mechanism 60 can be moved to the position corresponding to the stacking disc 91 on the conveying belt 50, and after the processed lead pipe is placed in the stacking disc 91, the lead pipe on the stacking disc 91 is pushed by the pushing cylinder 94 to arrange, which is convenient for centralized stacking of the finished lead pipe and saves the subsequent manual stacking process.

[0064] In some embodiments, an improved embodiment of the above-mentioned first clamping jaw mechanism 60 can adopt the structure as shown in Figure 1 . Referring to Figure 1 , multiple first clamping jaw mechanisms 60 are arranged along the extension path of the conveying belt 50, and each adjacent two stations share one first clamping jaw mechanism 60.
