Description

Technical Field

[0001] This invention relates to the field of tube forming machine technology, and specifically to a multifunctional tube forming machine. Background Technology

[0002] A pipeline is a device made up of pipes, pipe fittings, valves, etc., used to transport gases, liquids, or fluids containing solid particles. During the manufacturing process, pipelines sometimes require convex pipework.

[0003] Currently, pipes are generally processed using a pipe forming machine. However, when using a pipe forming machine, only one type of cam and concave wheel can be installed. When different types of pipes need to be processed, the original cam and concave wheel must be disassembled and then a cam and concave wheel that are compatible with the pipe must be installed to meet the processing requirements. This not only increases labor costs, but also requires waiting time for the disassembly and installation of the cam and concave wheel, resulting in a decrease in production efficiency.

Detailed Implementation

[0027] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0028] Please see Figure 1 , Figure 2This embodiment provides a multi-functional tube forming machine, including a base 1, a bracket 3 welded to the base 1, a cam assembly 2 installed at the bottom of the bracket 3, the cam assembly 2 connected to a transmission mechanism 7, the transmission mechanism 7 and the cam assembly 2 being installed at the bottom of the bracket 3, the transmission mechanism 7 connected to a drive mechanism 4, the drive mechanism 4 driving the transmission mechanism 7 to rotate, thereby driving the cam assembly 2 to rotate, a frame mechanism 5 installed on the upper part of the bracket 3, at least one pressure roller mechanism 8 installed on the frame mechanism 5, the frame mechanism 5 connected to a lifting mechanism 6, the lifting mechanism 6 being installed on the bracket 3, the bracket 3 having a first mounting hole 301 corresponding to the lifting mechanism 6, the lifting mechanism 6 being able to adjust the height of the frame mechanism 5, and the frame mechanism 5 being rotatable.

[0029] The drive mechanism 4 provided in this application, such as Figure 2 , Figure 3 As shown, the system includes a drive motor 401, which is fixedly connected to a base 1. The drive motor 401 is connected to a reducer 402, which is connected to a drive wheel 404. The drive wheel 404 is connected to a drive shaft 403 at its shaft center. The drive shaft 403 is rotatably connected to a bracket 3 via a bearing. The transmission mechanism 7 includes a driven wheel 701, which is connected to a sleeve 702. A through hole is provided at the shaft center of the driven wheel 701. The bracket 3 is provided with a second mounting hole 302 corresponding to the sleeve 702. The second mounting hole 302 is used to install the sleeve 702. The drive motor 401 drives the cam assembly 2 to rotate.

[0030] The cam assembly 2 includes a cam 202. The outer wall of the cam 202 is provided with at least one protrusion 2021. The protrusion 2021 is annular and has a different outer diameter. The side wall of the cam 202 is connected to a screw 201. The sleeve 702 is inserted into the second mounting hole 302. The cam 202 is inserted into the sleeve 702. The screw 201 passes through the through hole of the driven wheel 701. The nut 703 is then tightened onto the screw 201. The cam assembly 2 and the transmission mechanism 7 are then mounted on the bracket 3.

[0031] In this embodiment, both the driving wheel 404 and the driven wheel 701 are gears. Driven by the drive motor 401, the driving wheel 404 rotates, which in turn drives the driven wheel 701 and the sleeve 702 to rotate. In some other embodiments, the driving wheel 404 and the driven wheel 701 can be pulleys, with the driving wheel 404 driving the driven wheel 701 to rotate via a belt.

[0032] In other embodiments, such as Figure 4 As shown, a slot 7021 is provided on the inner wall of the sleeve 702, and a rib 203 is provided on the outer wall of the connection between the cam 202 and the sleeve 702. After the rib 203 is inserted into the sleeve 702, when the driven wheel 701 rotates, the sleeve 702 drives the cam 202 to rotate. The rib 203 can prevent relative displacement between the cam 202 and the driven wheel 701.

[0033] This application also includes a lifting mechanism 6, such as Figure 5 , Figure 6 As shown, the lifting mechanism 6 is used to adjust the height of the frame mechanism 5, so that the pressure roller mechanism 8 installed on the frame mechanism 5 cooperates with the cam assembly 2 to achieve different combination states. The lifting mechanism 6 includes a flange 601, which is used to fix it to the frame mechanism 5. The flange 601 is fixedly connected to the support rod 602. The support rod 602 has four rows of threaded holes 6021. The distance between two adjacent threaded holes 6021 is the same as the distance between two adjacent protrusions 2021. A sliding sleeve 603 is fitted on the outside of the support rod 602. A threaded sleeve 604 is welded to the tube wall of the sliding sleeve 603. The threaded sleeve 604 is connected to the threaded hole 6021 with a screw. A sliding rod 605 is also welded to the upper end of the sliding sleeve 603. The sliding rod 605 passes through the bracket 3 and is slidably connected to the bracket 3. A movable block 606 is fixedly connected to the side wall of the sliding sleeve 603. The movable block 606 has an upward-opening threaded rod. The movable block 606 is threadedly connected to the lifting screw 607. The upper end of the lifting screw 607 passes through the bracket 3 and extends to the outside of the bracket 3. The lifting screw 607 is rotatably connected to the bracket 3 through a bearing. The top of the lifting screw 607 is fixedly connected to the handwheel 608. Rotating the handwheel 608 drives the lifting screw 607 to rotate. When the movable block 606 moves upward, it drives the sliding sleeve 603 and the support rod 602 to move upward, thereby driving the frame mechanism 5 to move upward. This makes the pressure roller mechanism 8 at the bottom of the frame mechanism 5 move away from the cam assembly 2, which is suitable for processing pipes with larger diameters. Rotating the handwheel 608 in the opposite direction drives the lifting screw 607 to rotate in the opposite direction, which drives the movable block 606 to move downward. This makes the frame mechanism 5 and the pressure roller mechanism 8 move downward. The pressure roller mechanism 8 moves closer to the cam assembly 2, which is suitable for processing pipes with smaller diameters. The lifting screw 607 is used to coarsely adjust the distance between the pressure roller mechanism 8 and the cam assembly 2.

[0034] This application also includes a pressure roller mechanism 8, such as Figure 7 , Figure 8As shown, at least one mounting bracket 501 is fixedly connected to the edge of the frame mechanism 5. Each mounting bracket 501 is of a different size and is used to mount pressure roller mechanisms 8 of different sizes. The mounting bracket 501 is U-shaped and is used to mount the pressure roller mechanism 8. The pressure roller mechanism 8 includes a pressure roller bracket 801, which is connected to a pressure roller 802 via a rotating shaft. An annular pressure groove 8021 is formed on the side wall of the pressure roller 802. A slot 8011 is formed at the top of the pressure roller bracket 801. The slot 8011 is inverted T-shaped and is used to connect an adjusting screw 8. 03. A support block (not shown in the figure) is fixedly connected to the end of the adjusting screw 803. The support block is embedded in the slot 8011. The adjusting screw 803 is threadedly connected to the mounting bracket 501. Rotating the adjusting screw 803 can drive the pressure roller bracket 801 to move. The upper end face of the pressure roller bracket 801 is fixedly connected to the movable rod 804. The movable rod 804 passes through and slides through the mounting bracket 501. Tightening the adjusting screw 803 can adjust the height of the pressure roller bracket 801 and the pressure roller 802, and can more precisely adjust the distance between the pressure roller 802 and the cam 202, thereby improving the processing accuracy.

[0035] In this invention, the drive mechanism 4 drives the cam assembly 2 to rotate. Compared with manually driving the cam assembly 2, it can reduce the use of manpower. The lifting mechanism 6 can roughly adjust the height of the frame mechanism 5, and the pressure roller mechanism 8 can finely adjust the height of the pressure roller 802. It is suitable for processing pipes of different diameters. The pressure roller mechanisms 8 of different sizes on the frame mechanism 5 cooperate with the protrusions 2021 of different outer diameters, so that one machine can press different types of pipes. It has high precision, can greatly save labor costs, and improve production efficiency.

[0036] Remove the screw at the threaded sleeve 604, rotate the frame mechanism 5 to rotate the support rod 602, adjust the pressure roller mechanism 8 at the bottom of the frame mechanism 5, and then screw the threaded sleeve 604 into the threaded sleeve 604 and the corresponding threaded hole 6021 to fix the position of the support rod 602 and fix the frame mechanism 5. The pressure roller mechanism 8 of different sizes can be rotated to the bottom of the frame mechanism 5, and the spacing of the threaded hole 6021 is the same as the spacing of the protrusion 2021. After moving the support rod 602, screw the screw into the threaded sleeve 604 and the corresponding threaded hole 6021 to make the pressure roller 802 correspond to the protrusion 2021, which is convenient for adjustment and use.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
