Description

Technical Field

[0001] The invention belongs to the technical field of pipe body processing, and in particular relates to a pipe body processing precision forming device. Background Art

[0002] Pipe processing mainly processes pipes required by industries such as industry, chemical industry, civil use, construction, and shipbuilding. The processing site is required to be spacious, and the pipe processing equipment must be able to meet the requirements of the pipe manufacturing process. The staff must be able to understand the drawings and complete the pipe production according to the process. Conventional processing facilities include pipe bending machines, beveling machines, grinders, electric welders, cutting machines, etc. During the pipe body processing process, after the formed steel pipe is processed, it is often necessary to further process the pipe body to obtain the required special-shaped steel pipe. However, the existing pipe body finishing lacks the ability to process the radial direction of the pipe body, and often uses manual methods to further press and shape the pipe body. The steel pipes produced in this way are of poor quality and have low processing efficiency. In addition, during the pipe body finishing process, when the cross-section of the pipe body needs to be processed into a polygon, the conventional pressing method is prone to breakage and deformation of the pipe body due to excessive pressure.

[0003] To address the shortcomings of the existing technologies, people have conducted long-term exploration and proposed various solutions. For example, a Chinese patent document discloses a production equipment for finishing steel pipes [201110268774.9], which includes a workbench, a hydraulic drive device, an automatic control system, and a steel pipe body. The workbench is respectively equipped with an upper frame, a machine base, a left frame, and a right frame. The lower portion of the upper frame is fixedly connected to an upper hydraulic jack, the upper portion of the machine base is fixedly connected to a lower hydraulic jack, and the ends of the upper and lower hydraulic jacks are respectively fixed with an upper arc body and a lower arc body that match the outer arc surface of the steel pipe body. A left hydraulic device is fixedly connected to the right side of the left frame, and the ends of the left upper hydraulic jack and the left lower hydraulic jack are both provided with a first cylinder. A right hydraulic device is fixedly connected to the left side of the right frame, which is symmetrical with the left hydraulic device, and the ends of the right upper hydraulic jack and the right lower hydraulic jack are both provided with a second cylinder.

[0004] The above solution solves the problem of low efficiency of steel pipe pressing to a certain extent, but the solution still has many shortcomings, such as the problem that the pipe body may break due to excessive pressing when processing special-shaped steel pipes. Summary of the Invention

[0005] The object of the present invention is to provide a tube body processing and fine forming device with reasonable design and effective control of pressing torque in order to solve the above problems.

[0006] To achieve the above objectives, the present invention employs the following technical solutions: a pipe body processing and precision forming device comprising a processing platform, on which are mounted a plurality of extrusion forming devices, each of which comprises a vertical extrusion assembly and a horizontal extrusion assembly. A clamping assembly connected to the processing platform is disposed between the vertical and horizontal extrusion assemblies. The vertical and horizontal extrusion assemblies each comprise a forming assembly opposing the clamping assembly. A correction assembly is disposed between adjacent extrusion forming devices. The multiple extrusion forming devices utilize the vertical and horizontal extrusion assemblies to apply extrusion torque to the pipe body, and utilize the forming assemblies to apply pressure and form the pipe in a step-by-step manner, thereby effectively controlling the extrusion torque and preventing excessive deformation or damage during the processing of special-shaped steel pipes.

[0007] In the aforementioned tube body processing and finishing device, the extrusion molding device includes an extrusion base and an extrusion top cover arranged in a vertically opposed relationship. A plurality of mutually parallel extrusion slide bars are connected between the extrusion base and the extrusion top cover. An extrusion slide is slidably mounted on the extrusion slide bars. Independent lifting drive assemblies are provided between the extrusion slide, the extrusion base, and the extrusion top cover, respectively. A locking assembly is provided between the extrusion base and the extrusion top cover, opposing the lifting drive assemblies. The extrusion molding device provides vertical lifting torque to the vertical extrusion assembly and the horizontal extrusion assembly.

[0008] In the aforementioned tube processing and finishing device, the lifting drive assembly includes a lifting seat body mounted on the side of the extrusion slide. The lifting seat body is threadedly engaged with a lifting screw, which is connected to the lifting motor via a variable speed gear set. A buffer assembly is installed between the lifting seat body and the extrusion slide. The lifting drive assembly achieves variable speed transmission and, in addition to providing lifting torque, also provides additional extrusion force for the vertical extrusion assembly.

[0009] In the aforementioned tube body processing and finishing device, the buffer assembly includes a buffer groove and a buffer strip disposed between and slidably connected to the lifting seat and the extrusion slide. An elastic reset member is installed between the buffer groove and the buffer strip. The lifting seat is slidably mounted with a buffer head opposing the extrusion slide via an elastic element. The extrusion slide is slidably mounted with a buffer rod via an elastic element. The extrusion slide has a buffer opening for inserting the buffer head. The end of the buffer rod opposes the buffer opening and abuts against the buffer head. A mutually fitting guide surface is provided between the buffer head and the buffer rod. The buffer rod extends outwardly relative to the extrusion slide and opposes the extrusion base or the extrusion top cover. The buffer assembly prevents direct contact and collision between the lifting seat and the extrusion base and the extrusion top cover, allowing the lifting drive assembly to maintain a high lifting rate.

[0010] In the aforementioned tube processing and finishing device, the locking assembly includes a bearing seat mounted on the extrusion cover, a lifting screw rotatably connected to the bearing seat, an extrusion barrel slidably connected to an extrusion slide rod mounted on the extrusion cover, and an electric push rod mounted on the extrusion cover. The extrusion slide rod has locking holes arranged axially along the extrusion slide rod for insertion of the electric push rod end. A threaded block slidably mounted on the bearing seat is connected to the telescopic end of the electric push rod, and the threaded block has a threaded section that meshes with the lifting screw. The locking assembly is primarily used to adjust the vertical height of the extrusion cover to meet the extrusion requirements of different tubes.

[0011] In the aforementioned apparatus for fine-forming a tube body, a vertical extrusion assembly includes an extrusion base fixed to one side opposite an extrusion slide, a first extrusion block movably mounted on the extrusion base, a first extrusion motor mounted inside the extrusion base, the first extrusion motor connected to a crank connecting rod via a speed change gear set, and the crank connecting rod movably connected to the first extrusion block; a horizontal extrusion assembly includes an extrusion screw fixed to one side opposite the extrusion slide, the extrusion screw being transmission-connected to a second extrusion motor, the extrusion screw having symmetrically arranged threaded sections with opposite thread directions, the extrusion screw being meshed with an extrusion barrel through the threaded sections, the extrusion barrel being rotationally connected to an extrusion push rod, and the other end of the extrusion push rod being movably connected to a second extrusion block slidably mounted on the extrusion slide; and a forming assembly including a forming block fixedly connected to the first and second extrusion blocks, the forming block having a W-shaped cross-section at one end. The vertical extrusion assembly and the horizontal extrusion assembly synchronously or asynchronously apply extrusion torque to the tube body, and in conjunction with the forming assembly, a special-shaped tube having a cross-shaped cross-section and a pointed end can be extruded to meet the requirements of building support and decoration.

[0012] In the aforementioned tube processing and finishing device, the clamping assembly includes a clamping bracket mounted on a processing platform, a clamping base mounted on the clamping bracket, and a clamping ring connected to the clamping base via a planetary gear set and a clamping motor. A plurality of clamping rollers are mounted on the inner side of the clamping ring, and an adaptive adjustment assembly is installed between the clamping rollers and the clamping ring. The clamping assembly restricts the relative orientation of the tube during introduction and prevents it from bouncing during the extrusion process.

[0013] In the aforementioned device for fine-forming tube processing, the adaptive adjustment assembly includes an adjustment frame fixedly connected to a clamping ring, a pair of adjustment blocks slidably connected to the adjustment frame, an elastic reset member disposed between the adjustment blocks, the adjustment blocks rotatably connected to the clamping rollers via adjustment arms, a damping structure disposed between the clamping rollers and the adjustment frame, the damping structure including a damping bar rotatably connected to the clamping rollers, the damping bar slidably connected to the adjustment frame, a top pressure bar slidably mounted within the damping bar, the top pressure bar end being coated with a friction block that fits and presses against the inner side of the clamping roller, a conical spring mounted between the friction block and the damping bar, and the conical spring being sleeved on the top pressure bar. When the tube is inserted into the clamping assembly, the adaptive adjustment assembly ensures that it fits and clamps against the surface of the tube, while limiting the rate of movement of the tube and accurately controlling the amount of tube introduction.

[0014] In the aforementioned tube processing and finishing device, the calibration assembly includes a calibration base mounted on a processing platform. The calibration base is connected to a pneumatic clamp via an electric push rod, which in turn is connected to a calibration block via an extension bar. Guide rollers are located inside the calibration block. A sensor assembly is mounted on the calibration base. The sensor assembly includes infrared sensors positioned at the front and rear of the electric push rod, and a light shield is located at the top of the calibration base. The calibration assembly is primarily used for step-by-step tube processing, adjusting the vertical height of the tube and guiding the tube into another clamping assembly.

[0015] In the aforementioned tube processing and fine-forming device, a fixed disk and a rotating disk are rotatably connected between the processing platform and the extrusion molding device. A planetary gear set is installed between the fixed disk and the rotating disk, and the planetary gear set is meshed with a rotating motor for transmission. The fixed disk is slidably connected to the processing platform, and an adjustment screw extending longitudinally is installed between them. The extrusion molding device can rotate as a whole relative to the processing platform, and its longitudinal relative orientation can be adjusted to meet the requirements of small-radius bending and deformation of the tube.

[0016] Compared with the existing technology, the advantages of the present invention are: the extrusion molding device applies vertical and horizontal extrusion torque to the tube body and extrudes it, and multiple extrusion molding devices extrude step by step to prevent the tube body from being excessively squeezed and broken; the buffer component has a good protective effect on the lifting drive component, thereby maintaining a high lifting rate and improving the response rate of the vertical extrusion component and the horizontal extrusion component; the clamping component and the correction component limit the relative position of the tube body during transmission, ensure its feeding accuracy, and avoid its deviation.

DETAILED DESCRIPTION

[0025] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1As shown, a device for fine-forming a tube body is provided, comprising a horizontally arranged processing platform 1, on which a plurality of extrusion molding devices 2 are movably mounted. In a normal state, the extrusion molding devices 2 are arranged along the same axis, and the extrusion molding devices 2 can be increased or decreased according to actual needs. The extrusion molding devices 2 have a vertical extrusion assembly 3 and a horizontal extrusion assembly 4, which apply extrusion torque to the tube body synchronously or asynchronously. A clamping assembly 5 connected to the processing platform 1 is provided between the vertical extrusion assembly 3 and the horizontal extrusion assembly 4 to prevent circumferential misalignment during the tube body processing. The vertical extrusion assembly 3 and the horizontal extrusion assembly 4 have a molding assembly 6 opposite to the clamping assembly 5. The extrusion die built into the molding assembly 6 is in direct contact with the tube body. Each extrusion molding device 2 is equipped with an independent molding assembly 6 to process and mold the tube body step by step. A correction assembly 7 is installed between adjacent extrusion molding devices 2. During the transmission of the tube body, the correction assembly 7 adjusts the vertical position of the tube body and guides the tube body to be accurately introduced into the clamping assembly 5 and the extrusion molding device 2.

[0027] like Figure 2 As shown, similar to the existing stamping machine, the extrusion molding device 2 in the present application also includes an extrusion base 21 and an extrusion top cover 22 arranged relative to each other in the upper and lower directions. A number of mutually parallel extrusion slide bars 23 are connected between the extrusion base 21 and the extrusion top cover 22. The space between the extrusion base 21 and the extrusion top cover 22 is the tube body processing space. Unlike the conventional stamping structure, an extrusion slide 24 is slidably mounted on the extrusion slide bar 23. Independent lifting drive assemblies are respectively provided between the extrusion slide 24 and the extrusion base 21 and the extrusion top cover 22. The lifting drive assembly provides a lifting torque for the extrusion slide 24. A locking assembly 9 opposite to the lifting drive assembly is provided between the extrusion base 21 and the extrusion top cover 22. When the extrusion top cover 22 is adjusted to a specified height, the locking assembly 9 fixes it to the extrusion slide bar 23.

[0028] Specifically, the lifting drive assembly includes a lift body 25 independently mounted on the side of the extrusion slide 24. This body 25 is threadedly engaged with a lifting screw 26, causing the body 25 to move up and down as the lifting screw 26 rotates. The lifting screw 26 is connected to a lifting motor 27 via a variable-speed gear train, maintaining low-speed, high-torque transmission. A buffer assembly 8 is installed between the lift body 25 and the extrusion slide 24. This buffer assembly 8 prevents direct impact with the extrusion base 21 or the extrusion cover 22 during the extrusion slide 24's ascent and descent.

[0029] like Figure 6As shown, under normal conditions, the lifting seat 25 and the extrusion slide 24 remain relatively locked. When the lifting seat 25 moves up and down to a designated position, it is unlocked. The buffer assembly 8 includes a buffer groove 81 and a buffer bar 82, which are slidably connected between the lifting seat 25 and the extrusion slide 24 to ensure that the lifting seat 25 and the extrusion slide 24 slide and displace in the vertical direction. An elastic reset member is installed between the buffer groove 81 and the buffer bar 82. The lifting seat 25 is slidably mounted with a buffer head 83 opposite to the extrusion slide 24 via an elastic member. The extrusion slide 24 is slidably mounted with a buffer rod 84 via an elastic member. The extrusion slide 24 has a buffer opening for the buffer head 83 to be inserted. The end of the buffer rod 84 is opposite to the buffer opening and abuts against the buffer head 83. A guide surface 85 is provided between the buffer head 83 and the buffer rod 84, which is in contact with each other. The buffer rod 84 extends outward relative to the extrusion slide 24 and faces the extrusion base 21 or the extrusion top cover 22. When the buffer rod 84 contacts and abuts against the extrusion base 21 or the extrusion top cover 22, the buffer rod 84 slides in the extrusion slide 24 and uses the guide surface 85 to push the guide surface 85 out of the buffer port, thereby unlocking and separating the lifting seat body 25 from the extrusion slide 24.

[0030] Furthermore, when the diameter of the tube to be processed is too small or the height of the tube production line is low, the locking assembly 9 is unlocked to adjust the height of the extrusion top cover 22, further limiting the sliding range of the extrusion slide 24. The locking assembly 9 includes a bearing seat 91 mounted on the extrusion top cover 22, and the lifting screw 26 is rotatably connected to the bearing seat 91. The bearing seat 91 maintains the rotational lubrication of the lifting screw 26. The extrusion top cover 22 is provided with an extrusion cylinder 92 that is slidably connected to the extrusion slide 23. The extrusion top cover 22 is installed with an electric push rod. The extrusion slide 23 has locking holes 93 arranged axially for inserting the end of the electric push rod; a threaded block 94 connected to the telescopic end of the electric push rod is slidably mounted on the bearing seat 91, and the threaded block 94 is provided with a threaded section that engages and transmits with the lifting screw 26. The electric push rod is plugged and locked with the extrusion slide 23, and the threaded block 94 is separated from the lifting screw 26. When the end of the electric push rod is pulled out from the locking hole 93 , the threaded block 94 is engaged with the lifting screw 26 for transmission, thereby providing a lifting driving torque for the extrusion top cover 22 .

[0031] In addition, the vertical extrusion assembly 3 includes an extrusion base 31 fixed to the opposite side of the extrusion slide 24. The extrusion base 31 is typically arranged in a pair, one above the other. A first extrusion block 32 is movably mounted on the extrusion base 31. A first extrusion motor 33 is mounted within the extrusion base 31. The first extrusion motor 33 is connected to a crank connecting rod 34 via a speed-changing gear set. The crank connecting rod 34 is movably connected to the first extrusion block 32. The rotation of the crank connecting rod 34 drives the first extrusion block 32 to periodically raise and lower the pressure relative to the extrusion base 31, thereby applying an extrusion torque to the tube body.

[0032] like Figure 5As shown, the horizontal extrusion assembly 4 includes an extrusion screw 41 fixed on the opposite side of the extrusion slide 24. The extrusion screw 41 is connected to the second extrusion motor 42. The extrusion screw 41 has symmetrically arranged thread segments with opposite thread directions. The extrusion screw 41 is respectively engaged with the extrusion barrel 42 through the thread segments. When the extrusion screw 41 rotates, the extrusion barrels 42 move closer or farther away from each other. The extrusion barrels 42 are respectively connected to the extrusion push rods 43, and the other ends of the extrusion push rods 43 are movably connected to the second extrusion block 44 slidably mounted on the extrusion slide 24. The extrusion push rods 43 convert the axial movement torque of the extrusion barrel 42 into the longitudinal pushing torque of the second extrusion block 44. The forming assembly 6 includes a forming block 45 fixedly connected to the first extrusion block 32 and the second extrusion block 44. The cross-section of the forming block 45 relative to one end is W-shaped. Each forming block 45 is in direct contact with the tube body and pressed tightly, so that the round tube or square tube is compressed and deformed into a special-shaped tube with a cross-shaped cross-section.

[0033] like Figure 3 As shown, the clamping assembly 5 corresponds to the extrusion molding device 2 in a one-to-one manner. Specifically, it includes a clamping bracket 51 mounted on the processing platform 1. The clamping bracket 51 is mounted on a clamping base 52. The clamping base 52 is connected to a clamping ring 53 via a planetary gear set and a clamping motor. The clamping ring 53 rotates relative to the clamping base 52 to adjust the circumferential angle. A plurality of clamping rollers 54 are mounted on the inner side of the clamping ring 53, and an adaptive adjustment assembly is installed between the clamping rollers 54 and the clamping ring 53. The surface of the clamping rollers 54 is coated with a non-slip layer. Under the action of the adaptive adjustment assembly, the clamping rollers 54 always adhere to the tube body.

[0034] like Figure 7 As shown, the adaptive adjustment assembly includes an adjustment frame 55 fixedly connected to the clamping ring 53. The adjustment frame 55 is slidably connected to a pair of adjustment blocks 56. An elastic return member is disposed between the adjustment blocks 56. The adjustment blocks 56 are rotatably connected to the clamping roller 54 via an adjustment arm 57. Supported by the elastic return member and the adjustment arm 57, the clamping roller 54 moves toward the center of the clamping ring 53. A damping structure 58 is disposed between the clamping roller 54 and the adjustment frame 55 to prevent the tube from being displaced relative to the extrusion molding device 2 due to excessive transmission speed. The damping structure 58 comprises a damping strip 581 rotatably connected to the clamping roller 54. The damping strip 581 is slidably connected to the adjustment frame 55. A pressure strip 582 is slidably mounted within the damping strip 581. The end of the pressure strip 582 is covered with a friction block 583 that presses against the inside of the clamping roller 54. A conical spring is mounted between the friction block 583 and the damping strip 581, and the conical spring is sheathed around the pressure strip 582. The greater the offset of the tube relative to the center of the clamping ring 53, the greater its weight. As the conical spring deforms under pressure, it applies a counter-pressure force to the friction block 583, increasing the frictional resistance against the clamping roller 54 and reducing the tube's transmission rate.

[0035] like Figure 4 As shown, the correction component 7 is arranged between adjacent extrusion molding devices 2, and specifically includes a correction base 71 installed on the processing platform 1. The upper end of the correction base 71 is connected to a pneumatic clamp 72 through an electric push rod, and the pneumatic clamp 72 is connected to a correction block 74 through an extension bar 73 to ensure that the clamping jaws of the pneumatic clamp 72 cooperate with the tube body. Guide rollers 75 are distributed on the inner side of the correction block 74. The pneumatic clamp 72 mainly limits the circumferential angle of the tube body and does not affect its axial sliding. A sensor component is provided on the correction base 71; the sensor component includes infrared sensors 76 respectively arranged in front and behind the electric push rod, and a light shield 77 is provided on the upper end of the correction base 71. When the tube body passes through the correction base 71, the infrared sensor 76 senses its relative position and promptly determines the relative position of the tube body and the extrusion molding device 2.

[0036] Preferably, a fixed disk 11 and a rotating disk 12 are installed between the processing platform 1 and the extrusion molding device 2, which are rotatably connected to each other. A planetary gear set is installed between the fixed disk 11 and the rotating disk 12, and the planetary gear set is engaged with a rotating motor for transmission. The extrusion molding device 2 rotates relative to the processing platform 1 to adjust its orientation. The fixed disk 11 is slidably connected to the processing platform 1, and a longitudinally extending adjustment screw 13 is installed between them. It cooperates with the fixed disk 11 and the rotating disk 12 for synchronous adjustment, so that the internal channel of each extrusion molding device 2 is curved to meet the extrusion bending requirements of the tube body.

[0037] To sum up, the principle of this embodiment is that multiple extrusion molding devices 2 on the processing platform 1 cooperate with each other, and the vertical extrusion component 3 and horizontal extrusion component 4 inside them apply multiple radial extrusion torques to the tube body, and the forming component 6 extrudes and molds the tube body, and extrudes the tube body step by step to obtain the desired special-shaped tube.

[0038] The specific embodiments described herein are merely illustrative of the spirit of the present invention.
