Description

Technical Field

[0001] This invention relates to the field of metal pipe processing technology, and specifically provides a production apparatus for special-shaped steel pipes. Background Technology

[0002] Shaped steel pipes are a general term for steel pipes with cross-sectional shapes other than round pipes. Methods for producing shaped pipes include cold drawing, electric welding, extrusion, and hot rolling. They are widely used in aviation, automotive, shipbuilding, mining machinery, agricultural machinery, construction, textiles, and boiler manufacturing. Currently, the processing of shaped steel pipes involves first heating one end of the raw material and then using a stamping machine to shrink the heated end. The round pipe is then cold-drawn using a die to form the shaped pipe.

[0003] Manufacturers of special-shaped tubes are usually equipped with multiple molds of different shapes to process various special-shaped tubes. Each mold is usually suitable for processing steel pipes of a corresponding diameter. This requires operators to classify the steel pipes and place them in front of the corresponding mold openings, which not only wastes manpower and is inefficient, but also poses a great danger to people transporting steel pipes between multiple cold drawing devices.

Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0020] Example 1 like Figure 1-8 As shown, a production device for special-shaped steel pipes includes a positioning mechanism, which is installed in front of multiple cold drawing machines arranged side by side. The positioning mechanism can transport the steel pipe to the front of any cold drawing machine. After the transport is completed, the steel pipe is aligned with the mold opening of the cold drawing machine.

[0021] A conveying mechanism, which is mounted on a positioning mechanism, is capable of pushing the steel pipe toward the cold drawing machine; The feeding mechanism is located above the conveying mechanism. The feeding mechanism stores multiple steel pipes and enables the steel pipes to fall intermittently onto the conveying mechanism. The conveying mechanism includes a first support frame 10 and a first motor 11 mounted on a positioning mechanism. The first support frame 10 is a rectangular frame with an opening at the top. Two bending plates 12 are disposed within the first support frame 10. Each bending plate 12 includes a lower vertical section 121 and an upper inclined section 122, wherein the inclined section slopes from top to bottom and from inside to outside. The two bending plates 12 abut against the inner wall of the first support frame 10 via a first spring 13. Under the elastic force of the first spring 13, the two bending plates 12 can jointly clamp the steel pipe. A first channel 14 is opened on the lower side of the first support frame 10, and a pushing block 15 is disposed within the first channel 14. The pushing block 15 can abut against one end of the steel pipe. The first motor 11 is drively connected to the pushing block 15, and the first motor 11 drives the pushing block 15 to reciprocate along the lateral direction of the first support frame 10. The pushing block 15 pushes the steel pipe to the front of the cold drawing machine mold opening.

[0022] The first motor 11 is equipped with a control module and a wireless signal receiving module that are electrically connected to each other. The wireless signal receiving module is wirelessly connected to the remote control, and the preferred wireless communication method is WLAN transmission.

[0023] The cold drawing machine is a commonly used device for processing irregularly shaped tubes and is existing technology, so it will not be described in detail in this invention.

[0024] As a further explanation of this embodiment, the first support frame 10 is provided with a first pulley 20 and a second pulley 21 at both ends. The first pulley 20 and the second pulley 21 are rotatably mounted on the positioning mechanism. The first pulley 20 and the second pulley 21 are connected by a belt drive through a first belt 22. One end of the push block 15 is fixed on the surface of the first belt 22. The first pulley 20 is coaxially fixed with the output shaft of the first motor 11.

[0025] As a further explanation of this embodiment, the positioning mechanism includes two parallel first support plates 30. First support legs 31 are fixed to the lower end faces of the two first support plates 30. The first support legs 31 are placed on the ground and support the first support plates 30. First guide rails 32 are fixed to both first support plates 30. Each first guide rail 32 is slidably engaged with a first slider 33. Specifically, a groove matching the inclined surface shape of the first guide rail 32 is formed at the bottom of the first slider 33. The first guide rail 32 is disposed within the groove and can slide relative to it. A first support frame 10 is fixed to both first sliders 33. A first motor 11 is fixed to the first slider 33 away from the cold drawing machine. A second motor 40 is fixed to the side wall of the first support leg 31. The second motor 40 is coaxially fixed to a third pulley 41. The third pulley 41 and a fourth pulley 42 are connected by a third belt 43. The third pulley 41 and the fourth pulley 42 are rotatably mounted on the first support leg 31. The third belt 43 is fixedly connected to the first slider 33.

[0026] The second motor 40 is equipped with a control module and a wireless signal receiving module that are electrically connected to each other. The wireless signal receiving module is wirelessly connected to the remote control, and the preferred wireless communication method is WLAN transmission.

[0027] As a further explanation of this embodiment, a first guide rod 50 is disposed inside the first spring 13. The inner diameter of the first spring 13 is slightly larger than the outer diameter of the first guide rod 50. One end of the first guide rod 50 is fixedly connected to the bending plate 12. The middle part of the first guide rod 50 passes through the outer wall of the first support frame 10 and slides with the first support frame 10. Specifically, multiple circular through holes are opened on the side wall of the first support frame 10. The first guide rod 50 passes through the circular through holes and can move along them. The other end of the first guide rod 50 is fixed with a first limiting block 51. The area of ​​the first limiting block 51 is larger than the area of ​​the circular through holes. The inner wall of the first limiting block 51 can abut against the outer wall of the first support frame 10.

[0028] As a further explanation of this embodiment, the feeding mechanism includes a feeding tray 60 inclinedly disposed on the conveying mechanism. The feeding tray 60 is fixedly connected to a discharge tray 61, which is horizontally disposed. Both the feeding tray 60 and the discharge tray 61 are fixedly provided with second support legs 62. Multiple second support legs 62 are placed on the ground for fixed support. The discharge tray 61 has a discharge hole 63, the size of which allows only one steel pipe to fall at a time. A cover plate 64 is slidably disposed below the discharge tray 61. Two sets of first sliding sleeves 70 and second sliding sleeves 71 are fixed to the lower end face of the cover plate 64. The two sets of first sliding sleeves 70 and second sliding sleeves 71 are respectively disposed near the side wall of the cover plate 64. A second guide rod 72 is inserted through the second sliding sleeve 71. A second limiting block 73 is fixed to one end of the second guide rod 72, and the other end of the second guide rod 72 is fixed to the first fixing block 74. The first fixing block 74 is fixed to the lower end face of the material feeding plate 61. A second spring 75 abuts between the second sliding sleeve 71 and the first fixing block 74. The second spring 75 is sleeved on the outside of the second guide rod 72. That is, one side of the second spring 75 abuts against the second sliding sleeve 71, and the other side of the second spring 75 abuts against the first fixing block.

[0029] As a further explanation of this embodiment, two first vertical rods 80 are fixed to the outer wall of the first support frame 10. The first vertical rods 80 can respectively abut against the second fixing block 81, and the second fixing block 81 is fixed to the lower end face of the cover plate 64.

[0030] To avoid interference between the bent plate 12 and the first vertical rod 80, two first notches 82 can be made on the bent plate 12 near the first vertical rod 80 at the projection position of the first vertical rod 80. Each first vertical rod 80 can be configured in the first notch 82 and move along it.

[0031] In use, the operator starts the second motor 40, which drives the third pulley 41 to rotate through its output shaft, which in turn drives the third belt 43 to rotate. The third belt 43 drives the first slider 33, which is fixed to it, to move along the lateral direction of the first support plate 30. The movement of the first slider 33 also drives the first support frame 10 and the first vertical rod 80 to move laterally. After the first vertical rod 80 abuts against the second fixed block 81, it pushes the cover plate 64 forward. The cover plate 64 no longer blocks the discharge hole 63, and the steel pipe falls from the discharge hole 63 and falls between the two bending plates 12. At this time, the second motor 40 is stopped, the second spring 75 is compressed and stores elastic potential energy, and the first spring 13 is also compressed. The two bending plates 12 can cooperate to clamp the steel pipe.

[0032] After the steel pipe falls between the two bending plates 12, the operator starts the second motor 40 and reverses its rotation. The reverse rotation of the second motor 40 drives the third belt 43 and the first slider 33 to move in the opposite direction to their previous movement, thus causing the first support frame 10 and the steel pipe to move in the opposite direction. The second spring 75 releases its elastic potential energy, pushing the second sliding sleeve 71 to reset the cover plate 64. When the steel pipe moves to align with the corresponding cold drawing machine mold opening, the operator shuts off the second motor 40 and starts the first motor 11. The output shaft of the first motor 11 drives the first pulley 20 to rotate, which in turn drives the first belt 22 to rotate, causing the push block 15 to move laterally. The push block 15 pushes the steel pipe towards the cold drawing machine. After the steel pipe is conveyed, the operator controls the first motor 11 to reverse its rotation. After the push block 15 resets, the first motor 11 stops rotating.

[0033] The upper surface of the inclined section 122 of the bending plate 12 can overlap with the lower surface of the dropping plate 61. If the diameter of the steel pipe falling between the bending plates 12 is too small, part of the second steel pipe will also fall into the bending plate 12. The inclined section 122 of the bending plate 12 will support this part of the second steel pipe. When the second motor 40 rotates in the opposite direction to drive the bending plate 12 back to its original position, the inclined surface of the inclined section 122 will contact the outer wall of the second steel pipe, which will slowly lift the second steel pipe until the upper surface of the inclined section 122 overlaps with the outer wall of the second steel pipe. At this time, the second steel pipe is lifted back into the dropping plate 61. The elastic potential energy released by the second spring 75 pushes the second sliding sleeve 71 to reset the cover plate 64.

[0034] It should be noted that the vertical height of the bending plate 12 should be greater than the maximum diameter of the transported steel pipe and less than 1.5 times the minimum diameter of the steel pipe.

[0035] Workers can control the start, stop, and forward / reverse rotation of the first motor 11 and the second motor 40 via remote control to complete the loading process of unprocessed steel pipes. There is no need for manual handling of steel pipes, and workers do not need to approach the cold drawing machine. The loading efficiency is higher and the safety factor is higher.

[0036] Example 2 like Figure 1-9 As shown, unlike Embodiment 1, in this embodiment, a third fixing block 90 and a fourth fixing block 91 are fixed on the two bent plates 12 respectively. A distance sensor 93 is fixed on the third fixing block 90. ​​The distance sensor 93 is electrically connected to the controller 94. The controller 94 is electrically connected to the first motor 11 and the second motor 40.

[0037] The controller 94 first controls the second motor 40 to start. After the steel pipe falls between the two bending plates 12, the two bending plates 12 move outward, driving the third fixing block 90 and the fourth fixing block 91 to move outward. The distance sensor 93 measures the distance between itself and the fourth fixing block 91 and feeds the parameter back to the controller 94. The controller 94 controls the second motor 40 to reverse. Based on the distance parameter fed back by the distance sensor 93, the controller determines the number of rotations of the second motor 40. After the second motor 40 stops executing the rotation command, the steel pipe is aligned with its corresponding cold drawing machine. Then, the controller 94 controls the first motor 11 to start. The process of conveying the steel pipe is the same as in Embodiment 1. After the conveying is completed, the controller 94 controls the first motor 11 to reverse, so that the push block 15 is reset.

[0038] The diameter of the steel pipe is measured by the distance sensor 93. The controller 94 determines which cold drawing machine the steel pipe needs to be transferred to based on the diameter. Then, it controls the start, stop and forward / reverse rotation of the first motor 11 and the second motor 40. The entire feeding process can be completed without human intervention, with a high degree of automation.

[0039] This invention is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort are within the scope of protection of this invention.
