Description

Technical Field

[0001] The present invention belongs to the technical field of continuous rolling lines, and in particular relates to a continuous rolling line production unit, system and process. Background Art

[0002] The pipe gang saw is an essential process equipment for cutting heads and tails and cutting to length during the production of seamless steel pipes on the continuous rolling line. The stability of this equipment directly affects the smooth operation and production capacity of the production line. It is a key process equipment in the continuous rolling line production process in addition to threading, binding, and stretching and reducing.

[0003] The pipe gang saw includes the main machine, auxiliary machine, electronic control system, hydraulic system, and electrical system. Among them, the auxiliary machine part is the concentrated point of failure of the entire pipe gang saw, which is mainly manifested in the problems of the cut-to-length accuracy not meeting customer requirements, inaccurate cut-to-length, and differences in the cut-to-length of a single steel pipe.

[0004] Traditional pipe stacks are transported using conveyor rollers. During the transportation process, there is relative movement between the pipe stack and the conveyor rollers, and the movement of multiple steel pipes in the pipe stack is not synchronized, which affects the alignment of multiple steel pipes in the pipe stack. A baffle is set at the end of the conveying pipeline, and alignment is achieved through the collision between the pipe stack and the baffle. It is easy for the multiple steel pipes in the pipe stack to be misaligned due to collision rebound. In addition, when sawing the pipe stack, the traditional method is to directly clamp the transmission to the pipe stack saw, which is easy to loosen the bundle and cause uneven pipe ends. The above factors will cause uneven pipe stacks and affect the production quality of the pipe stack. Summary of the Invention

[0005] The embodiments of the present invention provide a continuous rolling line production unit, system and process, aiming to overcome the technical problem that the existing pipe bank is easily misaligned during the conveying and clamping processes, thereby affecting the production quality of the pipe bank.

The clamping device includes a magnetic part for fixing the top of the tube row and a clamping part for fixing both sides of the tube row.

[0010] The continuous rolling line production unit provided in this embodiment has at least the following advantages compared to the prior art:

[0011] (1) The conveyor chain group conveys the tube row through the conveyor chain. During the conveying process, the conveyor chain and the tube row are relatively stationary, which solves the problem that multiple steel pipes in the tube row cannot be aligned due to speed difference. Since the conveyor chain and the tube row are relatively stationary, the outer surface of the tube row is prevented from being scratched, thereby improving the appearance quality.

[0012] (2) The alignment device actively pushes the tube row at the end of the conveyor chain group, avoiding the misalignment of the tube row caused by direct impact of the tube row and also avoiding damage to the equipment during the impact of the tube row;

[0013] (3) The clamping device uses the magnetic part on the top and the clamping parts on both sides to clamp and transport the pipe row, preventing uneven sawing caused by the loose bundle of the pipe row and improving the processing quality of the pipe row.

[0016] In combination with the first aspect, in a possible implementation, the chain bed is a wide-body chain bed to form gaps between adjacent steel pipes in the pipe row.

[0017] With reference to the first aspect, in one possible implementation, the alignment device includes:

[0018] an alignment bracket, disposed at the end of the conveyor chain group;

[0019] an alignment cylinder, disposed on the alignment bracket, wherein the piston rod of the alignment cylinder is located on a side facing the conveyor chain group and is telescopically adjustable along the first preset path; and

[0020] An alignment baffle is provided on the piston rod of the alignment cylinder, a plate surface of the alignment baffle is perpendicular to the first preset path, and the alignment baffle forms the alignment portion.

[0022] In combination with the first aspect, in a possible implementation, the alignment baffle and the elastic telescopic member are detachably connected via a threaded connection.

[0023] In combination with the first aspect, in a possible implementation, the clamping device includes:

[0024] Gantry trolley;

[0025] A clamping cylinder is provided on the gantry trolley, and the piston rod of the clamping cylinder is parallel to the up and down direction;

[0028] In a second aspect, an embodiment of the present invention further provides a continuous rolling line production system having two of the above-mentioned continuous rolling line production units, and a tube gang saw arranged between the two continuous rolling line production units, wherein the ends of the two continuous rolling line production units are respectively connected to opposite sides of the tube gang saw.

[0029] Compared with the prior art, the continuous rolling line production system provided in this embodiment has the following characteristics: in the actual production process, the continuous rolling line production units on both sides of the tube gang saw operate separately, and the tube gangs are alternately transported to the tube gang saw for cutting. The two continuous rolling line production units are used in combination with one tube gang saw to effectively improve production efficiency.

[0030] In a third aspect, an embodiment of the present invention further provides a continuous rolling line production process, comprising the following steps:

[0036] Compared with the prior art, the continuous rolling line production process provided by this embodiment uses a conveyor chain group to convey the pipe bank.

[0048] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0049] Please also refer to Figures 1 to 4 The continuous rolling line production unit provided by the present invention will now be described. The continuous rolling line production unit comprises a conveyor chain assembly 10, an alignment device 20, and a clamping device 30. The conveyor chain assembly 10 extends along a first preset path and includes a conveyor chain for receiving and transporting pipe banks. The alignment device 20 is disposed at the end of the conveyor chain assembly 10 and includes an alignment portion that reciprocates along the first preset path. The alignment portion is disposed toward the conveyor chain assembly 10 and is used to push the ends of the pipe banks on the conveyor chain assembly 10. The clamping device 30 is disposed at the top of the end of the conveyor chain assembly 10 and has the freedom to move along the first preset path. The clamping device 30 includes a magnetic portion for securing the top of the pipe banks and clamping portions for securing the sides of the pipe banks.

[0050] It should be noted that the tube bank is a row of multiple steel tubes 60 arranged in parallel.

[0051] In the continuous rolling line production unit provided in this embodiment, during the actual production process, after the tube row is produced, the material is turned over from the cooling bed to the conveyor chain group 10, and the conveyor chain group 10 transports the tube row until it reaches the end of the conveyor chain group 10. The tube row saw 40 is located at the end of the conveyor chain group 10. After the tube row reaches the end of the conveyor chain group 10, the conveyor chain group 10 stops, and the alignment part on the alignment device 20 extends. The alignment part realizes the alignment of multiple steel pipes 60 on the tube row by pushing back the tube row; then the tube row is fixed by the magnetic part and the clamping part on the clamping device 30 respectively. After fixation, the clamping device 30 moves along the first preset path to transport the tube row to the tube row saw 40 for sawing to complete the processing.

[0052] Compared with the prior art, the continuous rolling line production unit of the present invention has at least the following advantages:

[0053] (1) The conveyor chain group 10 conveys the tube row through the conveyor chain. During the conveying process, the conveyor chain and the tube row are relatively stationary, which solves the problem that multiple steel pipes 60 in the tube row cannot be aligned due to speed difference. Since the conveyor chain and the tube row are relatively stationary, the outer surface of the tube row is prevented from being scratched, thereby improving the appearance quality.

[0054] (2) The alignment device 20 actively pushes the tube row at the end of the conveyor chain group 10, avoiding the misalignment of the tube row caused by direct impact of the tube row and also avoiding damage to the equipment during the impact of the tube row;

[0055] (3) The clamping device 30 uses the magnetic part on the top and the clamping parts on both sides to clamp and transport the pipe bank, preventing uneven sawing caused by the loose bundle of the pipe bank and improving the processing quality of the pipe bank.

[0056] In some embodiments, a specific embodiment of the conveyor chain group 10 can be as follows Figures 1 to 2 The structure shown. Figures 1 to 2 The conveyor chain assembly 10 includes a plurality of chain beds 11 connected in sequence along a first preset path, with baffles 12 provided on opposite sides of the chain beds 11. The opposite sides of the chain beds 11 refer to the two sides of the chain beds 11 perpendicular to the first preset path. The baffles 12 prevent the steel pipes 60 from falling. By assembling a plurality of chain beds 11 to form a conveyor chain assembly 10, the number of chain beds 11 can be easily changed according to the actual conveying length, thereby enhancing applicability.

[0057] In some embodiments, an improved embodiment of the chain bed 11 can be adopted as follows Figure 2 The structure shown. Figure 2 The chain bed 11 is equipped with link supports that cooperate with the conveyor chain. The link supports are made of nylon, polyurethane, or black rubber. The material of the link supports is not limited to the three aforementioned materials; any low-hardness material can be used. By using a low-hardness material, the link supports provide sufficient friction to propel the tube row forward. Furthermore, when the alignment device 20 pushes the tube row backward, the link supports provide sufficient friction, preventing friction between the steel tubes 60 from causing all of them to synchronously retreat and misalign.

[0058] In some embodiments, a specific embodiment of the chain bed 11 can be as follows Figure 2 The structure shown. Figure 2 The chain bed 11 is wide, so that gaps are formed between adjacent steel pipes 60 in the pipe row. The specific width of the chain bed 11 is not limited here; its width is determined by the number of steel pipes 60 actually included in the pipe row. For example, if the number of steel pipes 60 is n, the diameter of the steel pipe 60 is D, and the gap between adjacent steel pipes 60 is d, then the actual supporting surface width of the wide chain bed 11 = n*D+(n-1)*d.

[0059] By increasing the width of the chain bed 11, the gap between adjacent steel pipes 60 is ensured, thereby avoiding the failure to align the steel pipes 60 due to the large friction between the steel pipes 60 when the pipe row is pushed back.

[0060] In some embodiments, a specific embodiment of the alignment device 20 can be as follows: Figure 3 The structure shown. Figure 3The alignment device 20 includes an alignment bracket 21, an alignment cylinder 22, and an alignment baffle 23. The alignment bracket 21 is located at the end of the conveyor chain assembly 10. The alignment cylinder 22 is mounted on the alignment bracket 21. The piston rod of the alignment cylinder 22 is located on the side facing the conveyor chain assembly 10 and is telescopically adjustable along a first preset path. The alignment baffle 23 is mounted on the piston rod of the alignment cylinder 22. The surface of the alignment baffle 23 is perpendicular to the first preset path, forming an alignment portion. The alignment cylinder 22 drives the alignment baffle 23 to extend and retract, actively advancing the alignment portion toward the tube row. Active control by the alignment cylinder 22 replaces manual adjustment, reducing labor intensity.

[0061] In some embodiments, an improved embodiment of the alignment device 20 may be as follows: Figure 3 See the structure shown. Figure 3 The opposite sides of the alignment baffle 23 are connected to the alignment bracket 21 via elastic telescopic members 24. The alignment baffle 23 has a first state in which it is spaced apart from the piston rod of the alignment baffle 23, and a second state in which it moves away from the alignment cylinder 22 under the push of the piston rod of the alignment cylinder 22. Regardless of which of the following methods the alignment cylinder 22 uses to drive the alignment baffle 23, in the initial state, the alignment baffle 23 is spaced apart from the piston rod of the alignment cylinder 22. When the tube row moves to the end of the conveyor chain group 10, the inertia of the tube row itself hits the alignment baffle 23, and the elastic telescopic rod is compressed, buffering the tube row. The alignment cylinder 22 is then driven, and the piston rod of the alignment cylinder 22 extends to push the alignment baffle 23 to move, achieving adjustment and alignment of the tube row. This structure prevents hard collisions of the tube row through the buffering effect of the elastic buffer member, reducing damage to the equipment and the tube row.

[0062] Specifically, the piston rod of the alignment cylinder 22 can simply abut the alignment baffle 23, or it can be directly fixed to the alignment baffle 23, as long as it can drive the movement of the alignment baffle 12. When the piston rod of the alignment cylinder 22 abuts the alignment baffle 23, an extrusion block 26 is provided at the end of the piston rod of the alignment cylinder 22. The extrusion block 26 is rotatably connected to the piston rod of the alignment cylinder 22 via a rotating shaft. The large area of the extrusion block 26 makes the extrusion process of the alignment baffle 23 more stable. Moreover, the extrusion block 26 is rotatably connected to the piston rod of the alignment cylinder 22, and can automatically adapt to the surface of the alignment baffle 23.

[0063] In some embodiments, an improved embodiment of the alignment baffle 23 can be as follows: Figure 3 See the structure shown. Figure 3 The alignment baffle 23 and the elastic member 24 are detachably connected via a threaded connector 25. The detachable alignment baffle 23 facilitates adjustment of the surface of the alignment baffle 23 to ensure that it is perpendicular to the first preset path and, in turn, perpendicular to the axial direction of the tube row, thereby improving the alignment accuracy of the tube row.

[0064] In some embodiments, a specific embodiment of the clamping device 30 can be as follows: Figure 4 See the structure shown. Figure 4 The clamping device 30 includes a gantry trolley 31, a clamping cylinder 32, an electromagnet 33, and a mechanical clamping arm 34. The clamping cylinder 32 is arranged on the gantry trolley 31, and the piston rod of the clamping cylinder 32 is parallel to the up and down direction; the electromagnet 33 is arranged at the end of the piston rod of the clamping cylinder 32, and the electromagnet 33 forms a magnetic attraction portion; the mechanical clamping arm 34 is rotatably arranged on the piston rod of the clamping cylinder 32, and the mechanical clamping arm 34 forms a clamping portion. The formation of the magnetic attraction portion by the electromagnet 33 facilitates the tightening and lowering of the tube bank by controlling the current on the electromagnet 33, which is convenient for operation; the mechanical clamping arm 34 and the piston rod of the clamping cylinder 32 are fixed at the top of the electromagnet 33, which facilitates the rotation and opening of the mechanical clamping arm 34 to clamp and release the tube bank, and the mechanical clamping arm 34 has a high control accuracy of the clamping force, thereby protecting the surface quality of the tube bank.

[0065] In some embodiments, an improved embodiment of the clamping device 30 can be as follows: Figure 4 See the structure shown. Figure 4 Servo encoders 35 are provided on opposite sides of the gantry trolley 31. After the clamping device 30 clamps the tube bank, it needs to be transported to the tube bank saw 40 for sawing. By providing the servo encoders 35, the feeding progress of the tube bank can be easily controlled, thereby improving the sawing accuracy and quality of the tube bank.

[0066] Based on the same inventive concept, an embodiment of the present application also provides a continuous rolling line production system, which has two of the above-mentioned continuous rolling line production units, and a tube gang saw 40 arranged between the two continuous rolling line production units, and the ends of the two continuous rolling line production units are respectively connected to the opposite sides of the tube gang saw 40.

[0067] Compared with the prior art, the continuous rolling line production system provided in this embodiment has the following characteristics: in the actual production process, the continuous rolling line production units on both sides of the tube gang saw 40 operate separately, and the tube gangs are alternately transported to the tube gang saw 40 for cutting. The two continuous rolling line production units are used in combination with one tube gang saw 40 to effectively improve production efficiency.

[0068] In some embodiments, an improved implementation of the above continuous rolling line production system can be implemented as follows: Figure 1 See the structure shown. Figure 1 The continuous rolling line production system also includes grating assemblies 50, respectively, located on opposite sides of the tube gang saw 40. After being secured by the clamping device 30, the tube gang is moved to the tube gang saw 40. Before reaching the tube gang saw 40, the tube gang passes through the grating assembly 50, which checks the alignment of the tube gang ends. If not, the grating assembly 50 retracts to the alignment device 20 for re-alignment. If aligned, sawing proceeds directly.

[0069] Based on the same inventive concept, the present application also provides a continuous rolling line production process, including the following steps:

[0070] S10: The cooling bed is unloaded and assembled, and the materials are unloaded to form tube rows;

[0071] S20: Turn the tube row to the starting end of the conveyor chain group 10, start the conveyor chain group 10, and transport the tube row to the end of the conveyor chain group 10;

[0072] S30: opening the alignment device 20 at the end of the conveyor chain group 10, and the alignment portion on the alignment device 20 extends toward the conveyor chain group 10 to achieve reverse pushing of the tube row on the conveyor chain group 10;

[0073] S40: The clamping device 30 at the top end of the conveyor chain assembly 10 is opened. The clamping device 30 fixes the top of the pipe row through the magnetic attraction portion and clamps both sides of the pipe row through the clamping portion. The clamping device 30 drives the pipe row to move to the pipe row saw 40.

[0074] S50: Start the pipe gang saw 40 to saw the pipe gang to complete the processing.

[0075] Compared with the prior art, the continuous rolling line production process provided by this embodiment uses a conveyor chain group 10 to convey the pipe bank. During the conveying process, the conveyor chain and the pipe bank are relatively stationary, which solves the problem of multiple steel pipes 60 in the pipe bank being unable to align due to speed differences. Since the conveyor chain and the pipe bank are relatively stationary, the outer surface of the pipe bank is prevented from being scratched, thereby improving the appearance quality. The alignment device 20 actively pushes the pipe bank at the end of the conveyor chain group 10, avoiding misalignment of the pipe bank caused by direct impact of the pipe bank and damage to the equipment during the impact of the pipe bank. The clamping device 30 uses a magnetic suction part at the top and clamping parts on both sides to achieve clamping and transportation of the pipe bank, preventing uneven sawing caused by loose bundles of the pipe bank and improving the processing quality of the pipe bank.

[0076] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
