Description

Technical Field

[0001] This utility model belongs to the field of tube cutting technology, specifically, it relates to a tube support device for a multi-line tube cutting machine. Background Technology

[0002] In the current field of pipe cutting, pipe cutting machines are widely used to achieve high-efficiency and high-precision cutting processes. Typically, traditional pipe cutting machines use multiple cutting lines wound between several rollers to form a multi-line cutting area, thus achieving simultaneous multi-point cutting of the pipe. To ensure cutting quality and the stability of the pipe during the cutting process, a support device is usually installed below the cutting area to provide necessary support and rotation for the pipe.

[0003] However, existing pipe support devices generally have the following shortcomings:

[0004] Firstly, in traditional pipe cutting systems, the pipe is mostly in a fixed state, and the cutting line is mainly pulled by the movement of the roller device to complete the cutting. This cutting method is prone to uneven force during the cutting process, and defects such as local tearing or burrs often appear on the cut surface. It is difficult to achieve high-quality and highly consistent multi-wire cutting results, especially when cutting long or heavy pipes, where stability issues are particularly prominent.

[0005] Secondly, the existing support device has an unreasonable design in the contact method between the support components and the tube when rotating, often resulting in slippage or rotational transmission failure. This directly reduces the stability and processing accuracy during the cutting process, making it difficult to meet precision machining requirements.

[0006] Therefore, there is an urgent need for a new type of support device that can optimize the tube support and rotational transmission method, improve cutting quality and processing consistency, in order to overcome the above problems. Utility Model Content

[0007] To address the aforementioned issues in the prior art, this utility model provides a pipe support device for a multi-line pipe cutting machine. The device is connected to the top material block by a tooling rod and rotated by a drive motor, thus solving the problems of uneven force, slippage, and poor cutting quality caused by unreasonable fixed cutting or support design in the prior art.

[0008] This utility model provides a pipe support device for a multi-line pipe cutting machine. 1. The multi-line pipe cutting machine includes multiple rollers, and cutting lines are wound between each roller to form a multi-line cutting area. The pipe support device is disposed below the multi-line cutting area and includes a pipe mounting assembly.

[0009] The pipe installation assembly includes a tooling bar, a first top material block, a drive motor, a second top material block, and a U-shaped bracket.

[0010] The tooling bar is axially disposed inside the U-shaped bracket, and its two ends are rotatably connected to the U-shaped bracket through the first top material block and the second top material block, respectively.

[0011] The tooling bar is connected to the first top material block and the second top material block by a protrusion and groove structure.

[0012] The drive motor is connected to the tooling bar and is used to drive the tooling bar to rotate around its axis.

[0013] In a preferred embodiment, the U-shaped bracket is further provided with at least two pairs of mounting holes symmetrically arranged at both ends, and a bearing is installed in each pair of mounting holes. At one end of the U-shaped bracket, a first top material block is provided in each pair of mounting holes, and at the other end, a second top material block is provided in each pair of mounting holes. Both the first top material block and the second top material block are provided with cylindrical rods, and the cylindrical rods of each first top material block and the second top material block are nested in the corresponding bearings.

[0014] In a preferred embodiment, the pipe installation assembly further includes a top force block and a driven wheel. The top force block is disposed at one end of the bracket, and at the other end of the bracket, the cylindrical rod of the second top force block protrudes from the outer side of the corresponding mounting hole of the bracket, and a driven wheel is sleeved on its outside.

[0015] In a preferred embodiment, the top force block is further described as a T-shaped lead screw structure, with its top plate end abutting against the end face of the first top material block and the corresponding bearing.

[0016] In a preferred embodiment, the pipe installation assembly further includes a nut and a locking wrench, and the screw portion of the T-shaped lead screw extends outward through the mounting hole of the bracket, and is sequentially fitted with a nut and a locking wrench.

[0017] In a preferred embodiment, the U-shaped bracket is further provided with two tooling bars arranged in parallel, each tooling bar being rotatably connected to the bracket via the second top material block, and each second top material block is fitted with a driven wheel.

[0018] In a preferred embodiment, the pipe installation assembly further includes a timing belt and a drive pulley, the drive pulley being positioned below the two driven pulleys, and the timing belt sequentially winding around and connecting the drive pulley and the two driven pulleys.

[0019] In a preferred embodiment, the drive motor is further disposed at the bottom of the U-shaped bracket, and its output shaft is connected to the drive wheel.

[0020] In a preferred embodiment, the pipe support device further includes a main support frame, on which a lifting system mounting seat is provided.

[0021] In a preferred embodiment, the pipe support device further includes a lifting system, which is fixedly installed in the lifting system mounting base and has a lifting end. The pipe installation assembly is installed on the lifting end of the lifting system.

[0022] The beneficial effects of this utility model are:

[0023] First, this utility model, by setting a tube support device below the multi-wire cutting area, adopts a structure in which a tooling rod and a U-shaped bracket are rotatably connected, and the tooling rod is driven to rotate by a drive motor. Compared with the prior art, this utility model achieves stable rotational support for the tube, reduces uneven force during the cutting process, lowers the incidence of local tearing or burrs on the cutting surface, and improves the cutting quality. At the same time, the tooling rod reliably engages with the top material block through a protrusion and groove structure, avoiding rotational slippage or transmission failure, further improving the durability and reliability of the device. It is suitable for high-precision multi-wire cutting operations of long or heavy tubes, and has the advantages of simple structure, reliable transmission, and high processing quality.

[0024] Secondly, in the preferred implementation, this invention provides multiple pairs of mounting holes and bearings at both ends of the U-shaped bracket, which, in conjunction with the nested installation of the cylindrical rods of the first and second top material blocks, enable the pipe support assembly to possess excellent rotational support functionality, thereby improving the overall structural stability and rotational flexibility. Simultaneously, the top force block employs a T-shaped screw structure, with its top plate end abutting against the first top material block and the corresponding bearing end face, enabling precise adjustment of the support force and effectively preventing loosening or displacement during pipe support. The inclusion of a nut and a locking wrench further enhances the screw's fixing effect.

[0025] Third, in the preferred implementation, this utility model uses two tooling bars arranged side by side, connected to a support bracket by a second top material block, and fitted with driven wheels on the outside, which can realize the synchronous rotation support of the two tooling bars. At the same time, a driving wheel is set below the two driven wheels, and the driving wheel is connected to the two driven wheels in sequence by a synchronous belt, so that the two driven wheels can be driven by one driving wheel to rotate synchronously. This structural design effectively ensures the synchronous rotation and stable support of the two tooling bars during the cutting process, and avoids problems such as rotation slippage and support instability caused by individual transmission or asynchrony.

[0026] Fourth, in the preferred embodiment, the drive motor of this utility model is installed at the bottom of the U-shaped bracket and drives the drive wheel to rotate, thereby realizing stable driving of the pipe support device; the main bracket and the lifting system mounting base on it provide a solid support foundation; the lifting system is fixed in the mounting base, and the pipe installation components can be adjusted up and down through its lifting end.

[0033] Example

[0034] As per the instruction manual Figure 1-2A pipe support device for a multi-wire pipe cutting machine is disclosed. The multi-wire pipe cutting machine includes multiple rollers, with cutting wires wound between the rollers to form a multi-wire cutting area. The pipe support device is located below the cutting area and includes a pipe mounting assembly 1, a lifting system 2, and a main support 3. The main support 3 has a lifting system mounting seat, and the lifting system 2 is fixedly installed within the lifting system mounting seat and has a lifting end. The pipe mounting assembly 1 is installed at the lifting end of the lifting system 2 and can move vertically with the lifting system 2 to below the cutting area to support the pipe 14. The pipe mounting assembly 1 includes a tooling rod 13, a drive motor 15, and a U-shaped bracket 19. The tooling rod 13 is axially disposed inside the U-shaped bracket 19, and its two ends are rotatably connected to the two sides of the U-shaped frame. The drive motor 15 is driven by the tooling rod 13 and drives the tooling rod 13 to rotate around its axis. In use, the pipe 14 is fitted onto the tooling bar 13, and as the tooling bar 13 rotates, the pipe 14 can rotate along its own axis.

[0035] The pipe installation assembly 1 also includes a locking wrench 10, a jacking block 11, a first jacking block 12, a tooling bar 13, a driven wheel 17, a second jacking block 18, and bearings. The U-shaped bracket 19 has several pairs of mounting holes symmetrically arranged at both ends, with a bearing installed in each pair of mounting holes. Both the first jacking block 12 and the second jacking block 18 have cylindrical rods. At one end of the U-shaped bracket 19, a first jacking block 12 is installed in each pair of mounting holes, and at the other end, a second jacking block 18 is installed in each pair of mounting holes. The cylindrical rods of each first jacking block 12 and second jacking block 18 are nested within the corresponding bearings to achieve rotational support.

[0036] In this application, the U-shaped bracket 19 has two pairs of mounting holes symmetrically arranged at both ends. Two tooling rods 13 are arranged side by side inside the bracket 19, and each tooling rod 13 has one pair of mounting holes at each end. The two ends of each tooling rod 13 abut against a first top material block 12 and a second top material block 18, respectively, thereby achieving axial support and rotational connection of the tooling rod through the top material blocks.

[0037] At one end of the bracket 19, a top force block 11 for applying preload is provided. The top force block 11 is a T-shaped lead screw structure, with its top plate end abutting against the end face of the first top material block 12 and the corresponding bearing. The screw part of the T-shaped lead screw extends outward through the mounting hole of the bracket 19, and is fitted with a nut and a locking wrench 10 in sequence. By tightening the nut and the locking wrench 10, the first top material block 12 and the tooling bar 13 are axially locked and fixed.

[0038] At the other end of the bracket 19, the cylindrical rod of the second top material block 18 protrudes from the outer side of the corresponding mounting hole of the bracket 19, and a driven wheel 17 is sleeved on its outside. The driven wheel 17 can further realize the auxiliary rotation or transmission function of the tooling bar 13, thereby improving the support stability and transmission efficiency.

[0039] The pipe mounting assembly 1 also includes a drive motor 15, a timing belt 16, and a drive pulley. The drive motor 15 is mounted at the bottom of the U-shaped bracket 19, and its output shaft is connected to the drive pulley via a coupling. The U-shaped bracket 19 contains two parallel tooling bars 13, each tooling bar 13 being rotatably connected to the bracket 19 via a second top material block 18, and each second top material block 18 is externally fitted with a driven pulley 17. The drive pulley is positioned below the two driven pulleys 17, and the timing belt 16 sequentially winds around and connects the drive pulley and the two driven pulleys 17, forming a synchronous transmission structure.

[0040] The drive motor 15 drives the driving wheel to rotate via a coupling. The driving wheel synchronously drives the two driven wheels 17 to rotate via a synchronous belt 16, thereby driving the second top block 18, the tooling bar 13, and the tube 14 sleeved on the tooling bar 13 to achieve overall synchronous rotation. The outer circumferential surface of the tooling bar 13 is coated with an adhesive layer, and the tube 14 is fixedly sleeved on the outer circumferential surface of the tooling bar 13. Through the arrangement of a single driving wheel, unified transmission of the two driven wheels 17 and their corresponding structures can be achieved, ensuring the synchronicity and stability of the rotation of the tube 14 during multi-wire cutting.

[0041] Furthermore, the tooling bar 13 has grooves at both ends, and the ends of the first top material block 12 and the second top material block 18 that contact the tooling bar 13 are provided with protrusions that cooperate with the grooves. Through the interlocking connection between the protrusions and the grooves, slippage of the tooling bar 13 relative to the first top material block 12 and the second top material block 18 can be effectively prevented during the rotation driven by the drive motor 15, ensuring the reliability and accuracy of the rotational transmission.

[0042] In this application, the lifting system 2 includes a servo motor, a coupling, a ball screw, a screw nut seat, a bearing seat with bearings, a linear guide rail, and a slider. The servo motor is fixed to the lower outer side of the worktable support 20, and its output shaft is connected to the ball screw via the coupling. The coupling, ball screw, screw nut seat, and bearing seat with bearings are located in the lifting system mounting base of the main support 3. Both ends of the ball screw are supported in the lifting system mounting base by the bearing seats with bearings, converting the rotational motion of the servo motor into linear propulsion. The screw nut seat is sleeved on the screw, and ball bearings are rotatably connected to the screw. One side of the screw nut seat is connected to one side of the slider, and the other side of the slider is slidably connected to the guide rail inside the lifting system mounting base. The servo motor drives the ball screw to rotate, and the rotation of the ball screw drives the slider fixed on the screw nut seat to move up and down along the guide rail inside the lifting system mounting base.

[0043] The working principle of the pipe support device for a multi-line pipe cutting machine of this utility model is as follows:

[0044] The pipe support device uses a lifting system to move the pipe mounting assembly above the multi-wire cutting area, providing stable support and synchronous rotation drive for the pipe to be cut. During operation, the lifting system 2, driven by a servo motor, uses a ball screw and nut seat to convert the motor's rotational motion into vertical linear motion, allowing the pipe mounting assembly 1 to rise and fall along the guide rail. The tooling bar 13 in the pipe mounting assembly 1 serves as a rotating support body that contacts the pipe 14. The pipe 14 is fitted onto the tooling bar 13, and the drive motor 15 drives the drive wheel to rotate. The drive wheel then drives the driven wheel 17 to rotate simultaneously via a synchronous belt, thereby causing multiple tooling bars 13 to rotate synchronously. Because the tooling bar 13 is connected to the first top block 13 and the second top block 18 through grooves and protrusions to prevent slippage, stable force transmission is ensured during rotation, preventing slippage and improving rotational synchronization and reliability. The tube 14 rotates synchronously around its own axis under the drive of the tooling bar, providing a continuous and uniform contact surface for the cutting line, ensuring the accuracy and efficiency of multi-wire cutting.

[0045] This utility model discloses a pipe support device for a multi-wire pipe cutting machine. By setting a support mechanism below the multi-wire cutting area, and employing a structure where a tooling bar and a U-shaped bracket are rotatably connected, and a drive motor rotates the tooling bar, stable rotational support for long or heavy pipes is achieved. This reduces localized tearing or burrs on the cutting surface caused by uneven force during cutting, improving cutting quality. The tooling bar reliably engages with the top block through a protrusion and groove structure, preventing rotational slippage or transmission failure, enhancing durability and reliability. The device has multiple pairs of mounting holes and bearings at both ends of the U-shaped bracket, which are nested with the cylindrical rods of the first and second top blocks, improving overall stability and rotational flexibility. The top block uses a T-shaped screw structure, which allows for precise adjustment of the support force through contact between the top plate end and the bearing end face, effectively preventing support loosening or offset. Nuts and locking wrenches further enhance the screw's fixing effect. To further enhance the synchronous support effect, the device employs two parallel tooling bars, which are rotatably connected to the support frame via a second top material block. Driven wheels are fitted externally, and a driving wheel located between the two driven wheels is driven by a synchronous belt, achieving synchronous rotation support of the two tooling bars and avoiding support instability caused by asynchrony. The drive motor is installed at the bottom of the U-shaped support frame, providing stable drive for the entire support device via the driving wheel. The main support frame and its lifting system mounting base provide a solid foundation, and the lifting end allows for vertical adjustment of the pipe installation components. This results in a compact overall structure, reliable operation, stable transmission, and advantages such as simple structure and high processing quality.
