Description

Technical Field

[0001] This invention relates to the field of steel pipe processing technology, and in particular to a seamless steel pipe processing feeding machine. Background Technology

[0002] Steel pipes are hollow steel products whose length is much greater than their diameter or circumference. Steel pipes are widely used in modern society, such as in the petrochemical industry and heat exchangers. In conventional production, long steel pipes need to be cut into smaller sections by a cutting machine. However, due to the large net weight and long length of the steel pipes, the operation of feeding and cutting them is very troublesome.

[0003] A search revealed Chinese patent application number 202011641501.X, which discloses a steel pipe processing feeding machine, comprising a first feeding component, a transport component, a second feeding component, a fixing component, a cutting component, and a third feeding component. The first feeding component is horizontally arranged, the transport component is located beside the first feeding component, the second feeding component is located beside the transport component, the fixing component is located on the second feeding component and is connected to the transport component, the cutting component is located on the second feeding component, and the third feeding component is located on the second feeding component. The third feeding component is connected to the second feeding component on the side; the first feeding component includes a feeding frame, a feeding base plate, two feeding fixing frames, two belts, two feeding side plates, two first motor fixing plates, two first drive motors, four rotating spindles, four pulleys, four rotating discs and four fixed columns. The feeding frame is horizontally set on the ground, and the two feeding fixing frames are symmetrically set on the side of the feeding frame. The feeding base plate is set on the two feeding fixing frames. The four rotating spindles pass through the two ends of the two feeding frames respectively and are rotatably engaged with the two feeding frames.

[0004] The steel pipe processing and feeding machine in the aforementioned patent has the following shortcomings: The device uses four rotating discs to drive two feeding side plates to rotate, thereby moving the steel pipes one by one from the feeding rack to the feeding base plate, and then the feeding side plates move them one by one to the transport assembly. This allows for orderly feeding of steel pipes without the need for manual handling. However, in actual use, the first feeding assembly transfers the steel pipes by rotating the feeding side plates. Since the steel pipes are relatively heavy, the rotation of the feeding side plates lifts them up, and then the steel pipes slide down into the next slot using their own weight. During the descent, the steel pipes experience a significant impact and make a loud noise, which may damage them. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the existing technology and to propose a seamless steel pipe processing feeding machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A seamless steel pipe processing feeding machine includes an adjustable base, a feeding section one, and a feeding section two.

[0008] Both the first feeding part and the second feeding part are fixedly installed on the top of the adjusting base, and the second feeding part is located on the back of the first feeding part.

[0009] The feeding unit includes a limiting unit, a lifting unit, and a control unit. The limiting unit includes a limiting platform group, the lifting unit includes a lifting platform group, and the control unit includes multiple multi-crankshafts. The limiting platform group and the lifting platform group are spaced apart, and the lifting platform group moves up and down relative to the limiting platform group. The multiple multi-crankshafts drive the multiple lifting platforms to move.

[0010] The second feeding section includes a support frame. Multiple transmission roller shaft groups and multiple auxiliary roller shaft groups are equidistantly arranged on the upper surface of the support frame. The multiple transmission roller shaft groups and multiple auxiliary roller shaft groups are spaced apart. A lifting pressure plate is provided at the top of the support frame. Multiple clamping roller shafts are equidistantly arranged on the lower surface of the lifting pressure plate.

[0011] As a preferred embodiment of the present invention: the limiting platform group includes a limiting platform one, a plurality of limiting platforms two are equidistantly arranged on the back of the limiting platform one, and a limiting platform three is arranged on the back of the plurality of limiting platforms two.

[0012] As a preferred embodiment of the present invention: a supporting base plate is fixedly connected to the bottom end of the limiting platform assembly, and two limiting side plates are fixedly connected to the upper surface of the supporting base plate, and the two limiting side plates are respectively fixedly installed on both sides of the limiting platform.

[0013] Based on the aforementioned scheme: connecting grooves are provided on the back of the first limiting platform and the multiple second limiting platforms; multiple auxiliary rollers are rotatably mounted at equal intervals on the front of the multiple second limiting platforms and the multiple third limiting platforms; and multiple auxiliary rollers are rotatably mounted at equal intervals on the top of the third limiting platform.

[0014] As a preferred embodiment of the present invention: the lifting platform assembly includes a first lifting platform, a plurality of second lifting platforms are equidistantly arranged on the back side of the first lifting platform, and a plurality of third auxiliary rollers are rotatably mounted equidistantly on the top of the first lifting platform and the plurality of second lifting platforms.

[0015] Based on the aforementioned scheme: the bottom end of the lifting platform is fixedly connected to a connecting base plate, and the bottom end of the connecting base plate is fixedly connected to multiple lifting connecting arms at equal intervals. The bottom end of the lifting connecting arms is provided with a rotating connecting groove, and multiple connecting shaft holes are provided at equal intervals on both sides of the rotating connecting groove.

[0016] As a preferred embodiment of the present invention: multiple connecting journals of the multi-crank crankshaft are rotatably connected to connecting rocker arms, the tops of the multiple connecting rocker arms are rotatably mounted inside the rotating connecting groove, and both ends of the multiple multi-crank crankshafts are rotatably connected to connecting side plates.

[0017] Based on the aforementioned scheme: a positioning base plate is fixedly connected to the bottom end of the two connecting side plates, and multiple supporting columns are fixedly connected to the upper surface of the positioning base plate, with the multiple supporting columns being fixedly connected to the supporting base plate.

[0018] Based on the aforementioned scheme: one end of the multi-crank crankshaft passes through and connects to the side plate and extends outward, and a transmission sprocket is fixedly installed at its extended end. An auxiliary sprocket is provided between two adjacent transmission sprockets, and a servo motor is connected to the transmission sprocket and the auxiliary sprocket.

[0019] As a preferred embodiment of the present invention: a plurality of limiting slide grooves are provided at equal intervals on the back of the support frame, and a limiting slide arm is slidably installed inside the limiting slide groove, wherein a lifting cylinder is fixedly connected to the bottom end of one of the limiting slide arms.

[0020] The beneficial effects of this invention are as follows:

[0021] 1. This seamless steel pipe processing and feeding machine, through the cooperation of the lifting platform group and the limiting platform group, lifts the steel pipe from a low position to a high position. During the lifting process, the steel pipe only rolls and slides horizontally, without falling or colliding, which fully ensures the safety of the steel pipe, does not produce noise, and the feeding speed of the steel pipe is faster.

[0022] 2. This seamless steel pipe processing and feeding machine limits the steel pipe by using a limiting side plate, allowing the steel pipe to move horizontally during the lifting process. This reduces the transport of the steel pipe by the two feeding sections, allowing the steel pipe to enter the steel pipe processing mechanism more quickly for processing and ensuring the overall feeding speed of the device.

[0023] 3. This seamless steel pipe processing feeding machine uses a lifting pressure plate to drive the clamping roller shaft in conjunction with the transmission roller shaft group and the auxiliary roller shaft group to clamp and transport the steel pipe, so that the steel pipe can stably enter the steel pipe processing mechanism and ensure the stability of steel pipe processing.

[0032] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0033] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0034] Example 1:

[0035] A seamless steel pipe processing feeding machine, such as Figures 1 to 6 As shown, the device includes an adjusting base 1, a feeding section 1 2, and a feeding section 2 3. The adjusting base 1 can be assembled into components as needed, which can drive the feeding section 1 2 and the feeding section 2 3 to adjust their horizontal and vertical positions, so that the device can be connected to steel pipe cutting devices, steel pipe drilling and grooving devices, steel pipe hole enlarging devices, etc.

[0036] Both the first feeding section 2 and the second feeding section 3 are fixedly installed on the top of the adjusting base 1. The second feeding section 3 is located on the back of the first feeding section 2. The first feeding section 2 lifts the steel pipe to a height and guides it into the second feeding section 3. The second feeding section 3 then guides the steel pipe into the steel pipe processing device. The steel pipe is guided into the first feeding section 2 through an inclined platform (not shown).

[0037] The feeding unit 2 includes a limiting unit 21, a lifting unit 22 and a control unit 23. The control unit 23 controls the lifting unit 22 to move up and down reciprocally. The limiting unit 21 limits the lifting unit 22 and the steel pipe and adjusts the horizontal position of the steel pipe during the lifting process.

[0038] The limiting unit 21 includes a supporting base plate 211, and two limiting side plates 212 are welded to the upper surface of the supporting base plate 211, such as... Figure 2 As shown, the projection of the limiting side plate 212 onto the upper surface of the supporting base plate 211 forms an angle with the horizontal transverse axis of the supporting base plate 211, with the angle ranging from 30 to 45 degrees.

[0039] A limiting platform assembly is provided between the two limiting side plates 212. The limiting platform assembly includes a first limiting platform 213, and multiple second limiting platforms 214 are equidistantly arranged on the back of the first limiting platform 213. A third limiting platform 215 is provided on the back of the multiple second limiting platforms 214. Figure 3 As shown, the heights of the first limiting platform 213, multiple second limiting platforms 214 and third limiting platforms 215 increase sequentially and are attached to each other in sequence, all of which are fixedly installed on the upper surface of the support base plate 211.

[0040] The back of the first limiting platform 213 and the multiple second limiting platforms 214 are provided with connecting grooves 218, which pass through the support base plate 211. The front of the multiple second limiting platforms 214 and the third limiting platform 215 is provided with a groove 1. Multiple auxiliary rollers 217 are rotatably installed at equal intervals inside the groove 1. The top of the third limiting platform 215 is provided with a groove 2. Multiple auxiliary rollers 216 are rotatably installed at equal intervals inside the groove 2.

[0041] The lifting unit 22 includes a connecting base plate 221. A lifting platform assembly is provided on the upper surface of the connecting base plate 221. The lifting platform assembly includes a first lifting platform 222, and multiple second lifting platforms 223 are equidistantly arranged on the back of the first lifting platform 222. Figure 4 As shown, the heights of lifting platform 222 and multiple lifting platforms 223 increase sequentially.

[0042] The top of the lifting platform 1 222 and the multiple lifting platforms 223 are all provided with a groove 3. Multiple auxiliary rollers 3 224 are rotatably installed at equal intervals inside the groove 3. The lifting platform 1 222 is slidably installed inside the connecting slide groove 218 on the back of the limiting platform 1 213. The multiple lifting platforms 223 are slidably installed inside the connecting slide groove 218 on the back of the multiple limiting platforms 214 in sequence.

[0043] like Figure 4 As shown, multiple lifting connecting arms 225 are welded at equal intervals to the bottom end of the connecting base plate 221. A rotating connecting groove 226 is provided at the bottom end of the lifting connecting arm 225. Multiple connecting shaft holes 227 are provided at equal intervals on both sides of the rotating connecting groove 226.

[0044] like Figure 6 As shown, the control unit 23 includes a positioning base plate 231, which is fixedly installed on the top of the adjusting base 1 by bolts. Both sides of the upper surface of the positioning base plate 231 are welded with connecting side plates 232, and multiple multi-crankshafts 234 are rotatably installed between the two connecting side plates 232 at equal distances.

[0045] Multiple connecting journals of the multi-crank crankshaft 234 are rotatably connected to connecting rocker arms 235, and the multiple connecting journals are all located on the same side of the main journal. The tops of the multiple connecting rocker arms 235 are rotatably mounted inside the rotating connecting groove 226 via pins.

[0046] Multiple multi-crankshafts 234 rotate synchronously, driving the connecting rocker arm 235 to move via the connecting journal. The connecting rocker arm 235, through the lifting connecting arm 225, drives the connecting base plate 221 to reciprocate up and down, thereby driving the lifting platform assembly to move synchronously. Figure 1 , Figure 2 , Figure 4 and Figure 6 As shown, the control unit 23 and the lifting unit 22 are in their initial state.

[0047] One end of the multi-crank crankshaft 234 passes through the connecting side plate 232 and extends outward. A transmission sprocket 236 is fixedly installed at the extended end. An auxiliary sprocket 237 is provided between two adjacent transmission sprockets 236. The auxiliary sprocket 237 is rotatably connected to the connecting side plate 232. The transmission sprocket 236 and the auxiliary sprocket 237 are connected to a servo motor 233 via a chain drive. The servo motor 233 is fixedly installed on the corresponding connecting side plate 232.

[0048] Multiple support columns 238 are fixedly connected to the upper surface of the positioning base plate 231. The multiple support columns 238 are fixedly connected to the support base plate 211, so that the limiting unit 21 and the control unit 23 remain relatively stable.

[0049] In this embodiment, during use, the steel pipe is placed at the top of the inclined platform, the top of the inclined platform is set as an inclined surface, and the lower end of the inclined surface is horizontal and connected to the upper surface of the limiting platform 213; then the servo motor 233 is started, and the servo motor 233 moves as follows... Figure 6 Under the action of the transmission sprocket 236 and the auxiliary sprocket 237 shown, multiple multi-crankshafts 234 are driven to rotate synchronously.

[0050] The multi-crank crankshaft 234 drives the connecting rocker arm 235 to move through the connecting journal. The connecting rocker arm 235 drives the connecting base plate 221 to move up and down through the lifting connecting arm 225, which in turn drives the lifting platform group to move synchronously. This causes the first lifting platform 222 and multiple second lifting platforms 223 to move up and down inside the connecting slide groove 218.

[0051] During the above movement, the steel pipe first rolls into the top of the limiting platform 213, and then rolls to the top of the lifting platform 222. The lifting platform 222 lifts the steel pipe, so that the steel pipe enters the top of the limiting platform 214. Under the lifting of the lifting platform 223, the steel pipe is lifted in sequence under the limiting of the limiting platform 214, and finally lifted to the top of the limiting platform 315.

[0052] The steel pipe is raised to a higher height under the combined action of the lifting platform group and the limiting platform group. During this process, the steel pipe is simultaneously restricted by the limiting side plate 212. With the cooperation of auxiliary roller 1 216 and auxiliary roller 3 224, the steel pipe gradually moves in a horizontal position.

[0053] Example 2:

[0054] A seamless steel pipe processing feeding machine, such as Figure 1 and Figure 7 As shown, this embodiment makes the following improvements based on Embodiment 1:

[0055] The second feeding section 3 includes a support frame 31, which is fixedly installed on the top of the adjusting base 1. The limiting platform 3 215 guides the steel pipe into the top of the support frame 31. Multiple transmission roller shaft groups 32 and multiple auxiliary roller shaft groups 33 are equidistantly arranged on the upper surface of the support frame 31. The transmission roller shaft group 32 includes multiple transmission roller shafts equidistantly arranged, and the auxiliary roller shaft group 33 includes multiple auxiliary roller shafts equidistantly arranged.

[0056] Multiple drive roller shaft groups 32 and multiple auxiliary roller shaft groups 33 are arranged at intervals. A limit baffle is provided on the side of the auxiliary roller shaft group 33 away from the feeding part 2. The limit baffle is fixed to the support frame 31 by bolts to limit the rolling distance of the steel pipe and ensure the stability of the steel pipe.

[0057] One end of the transmission roller shaft passes through the support frame 31 and extends to the back of the support frame 31. A second transmission sprocket is fixedly installed at its extended end. An auxiliary sprocket is provided between two adjacent second transmission sprockets. The auxiliary sprocket is rotatably installed on the back of the support frame 31 via a rotating shaft.

[0058] A servo motor 36 is fixedly mounted on the back of the support frame 31. The transmission sprockets of the multiple transmission roller shaft groups 32 are connected to the output shaft of the servo motor 36 through auxiliary sprockets and chains, so that the multiple transmission roller shaft groups 32 rotate synchronously in the same direction.

[0059] The top of the support frame 31 is provided with a lifting pressure plate 34. Multiple clamping rollers 35 are rotatably mounted at equal intervals on the lower surface of the lifting pressure plate 34. The clamping rollers 35 cooperate with multiple transmission roller groups 32 and multiple auxiliary roller groups 33 to clamp the steel pipe and at the same time cooperate with the transmission roller groups 32 to transport the steel pipe. The outer walls of the transmission rollers, auxiliary rollers and clamping rollers 35 are all bonded with rubber sleeves.

[0060] Multiple limiting grooves 37 are equidistantly provided on the back of the support frame 31. Limiting sliding arms 38 are slidably installed inside the limiting grooves 37. Multiple limiting sliding arms 38 are welded to the lifting pressure plate 34. The bottom end of one of the limiting sliding arms 38 is fixedly connected to the telescopic end of the lifting cylinder 39. The lifting cylinder 39 drives the lifting pressure plate 34 to move up and down through the limiting sliding arm 38 to clamp the steel pipe, so that the feeding part 2 3 can clamp and transport steel pipes of various diameters.

[0061] In this embodiment, the loading section 2 guides the steel pipe to the top of the support frame 31, which is supported by multiple transmission roller shaft groups 32 and multiple auxiliary roller shaft groups 33, and is limited by a limiting baffle. Then, the lifting cylinder 39 is activated, which drives the lifting pressure plate 34 to descend through the limiting sliding arm 38, so that the clamping roller shaft 35 is in contact with the top of the steel pipe. Finally, the servo motor 36 is activated, which drives the multiple transmission roller shaft groups 32 to rotate, and guides the steel pipe into the steel pipe processing mechanism.

[0062] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
