Description

Technical Field

[0001] The utility model relates to the technical field of square tube processing, and more specifically, to an extrusion plastic device for square tube forming processing. Background Art

[0002] Square tube is a kind of square tube, which is made of steel plate or strip steel after processing and rolling. Square tube has a hollow cross-section and is widely used as a pipeline for conveying fluids, such as pipelines for conveying oil, natural gas, coal gas, water and certain solid materials.

[0003] In the processing and production of square tubes, in order to improve the density and uniformity of the material and improve the mechanical properties of the square tubes, it is usually necessary to extrude and shape the square tubes. During the extrusion process, the fiber streamlines of the metal material can be distributed along the length of the square tube, thereby enhancing the longitudinal strength and rigidity of the square tube, and the extrusion shaping can achieve precise control of the shape and size of the square tube. At present, the extrusion shaping device of the square tube is usually realized by an extrusion roller. The extrusion roller can limit and extrude the square tube while transporting the square tube, and can shape a square tube with a specific size. However, the current extrusion roller is usually integrated and cannot be adjusted in real time according to the required size of the square tube. When the size of the required square tube changes, the device needs to be stopped to disassemble and replace the extrusion roller, which increases the workload and reduces the work efficiency. Therefore, it needs to be improved and optimized. Utility Model Content

[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] like Figures 1 to 7 As shown, the utility model provides an extrusion plastic device for square tube forming processing, comprising an extrusion bin 1, a square tube 2 is movably arranged inside the extrusion bin 1, and a motor 3 is fixedly installed on the front outer wall of the extrusion bin 1;

[0031] There are two sets of extrusion shaping mechanisms, both of which are rotatably mounted on the upper and lower sides of the square tube 2;

[0032] The extension mechanism is fixedly arranged inside the extrusion shaping mechanism;

[0033] A lifting mechanism, fixedly mounted on the top of the extrusion bin 1;

[0034] There are two groups of extrusion and shaping mechanisms, and the lower extrusion and shaping mechanism is rotatably arranged inside the extrusion bin 1, and the upper extrusion and shaping mechanism is rotatably installed inside the lifting mechanism;

[0035] The lower extrusion shaping mechanism includes an extrusion roller 4 rotatably installed inside the extrusion bin 1, one end of the extrusion roller 4 is fixedly connected to the output shaft of the motor 3, a connecting bin 11 is fixedly opened inside the extrusion roller 4, there are four groups of connecting bins 11, and connecting rods 9 are movably installed inside the four groups of connecting bins 11, there are four groups of connecting rods 9, and they are all fixedly connected to the fixed block 7, the fixed block 7 is fixedly connected to one end of the extrusion roller 2 5, the other end of the extrusion roller 2 5 is fixedly connected to the rotating rod 6, and the rotating rod 6 is movably sleeved on the outer wall of the extrusion bin 1.

[0036] When it is necessary to extrude and shape the square tube 2, the staff places the square tube 2 between the two groups of extrusion rollers 1 4 and 2 5, and starts motor 1 3 and motor 3 19 to make the extrusion rollers 1 4 and 2 5 start to rotate. The extrusion rollers 1 4 and 2 5 can extrude and shape the square tube 2 while transporting it. When the first batch of square tubes 2 are extruded and shaped, the size needs to be adjusted. At this time, the staff starts motor 2 12. The operation of motor 2 12 drives the threaded rod 13 to rotate. The rotation of the threaded rod 13 drives the extension block 8 threadedly connected to it to move. At this time, the extension block 8 is restricted by the storage bin 10, so that the extension block 8 begins to extend outward, and the outward movement of the extension block 8 causes the fixed block 7 to pull the connecting rod 9, further making the connecting rod 9 move along As the connecting bin 11 moves outward, the displacement of the fixed block 7 also pushes the squeezing roller 25 to move until the distance between the squeezing roller 14 and the squeezing roller 25 reaches a suitable distance. The staff then stops the motor 21, and then pushes the ranging rod 21 downward to move the ranging rod 21 downward along the bracket 20, and makes the roller 24 and the outer wall of the square tube 2 conflict with each other. At this time, the staff rotates the fastener 23 to fix the ranging rod 21. At this time, the staff can observe the height of the square tube 2 through the scale 22. When the measurement is completed, the staff starts the cylinder 15 to drive the pressure plate 17 to move. At this time, the pressure plate 17 moves downward along the movable groove 16 until the squeezing roller 14 and the squeezing roller 25 conflict with the top of the square tube 2, thereby completing the adjustment of the extrusion shaping operation.

[0037] The threaded rod 13 is driven to rotate by the operation of the motor 2 12, and the rotation of the threaded rod 13 drives the extension block 8 threadedly connected thereto to move, so that the extension block 8 pushes the extrusion roller 2 5, further increasing the distance between the extrusion roller 1 4 and the extrusion roller 2 5, and then the operation of the cylinder 15 causes the pressure plate 17 to move downward, and further adjust the height of the extrusion roller 1 4 and the extrusion roller 2 5. Compared with the traditional device, the device adjusts the extrusion width of the extrusion shaping mechanism by setting the extension mechanism, and then adjusts the extrusion width of the extrusion shaping mechanism by setting the lifting mechanism, which effectively reduces the workload, and the device can be adjusted during extrusion, thereby improving work efficiency and saving time.

[0038] Among them, it also includes a distance measuring mechanism fixedly installed on the top of the extrusion bin 1;

[0039] The distance measuring mechanism includes a bracket 20 fixedly installed on the top of the extrusion bin 1, the bracket 20 is located on the right side of the lifting mechanism, one end of the bracket 20 is rotatably provided with a fastener 23, the inner part of the bracket 20 is movably sleeved with a distance measuring rod 21, and the bottom of the distance measuring rod 21 is rotatably provided with a roller 24, and the roller 24 and the square tube 2 are in contact with each other.

[0040] The staff pushes the ranging rod 21 downward, so that the ranging rod 21 moves downward along the bracket 20, and makes the roller 24 and the outer wall of the square tube 2 conflict with each other. At this time, the staff turns the fastener 23 to fix the ranging rod 21. At this time, the staff can observe the height of the square tube 2 through the scale 22.

[0041] By pushing the ranging rod 21, the ranging rod 21 moves downward along the bracket 20, and the roller 24 and the square tube 2 are in conflict with each other. Compared with the traditional device, the device uses the mutual conflict between the roller 24 and the square tube 2, and then fixes the ranging rod 21 with the fastener 23, so that the staff can observe the scale 22 more stably, and the adjustment of the squeezing roller 1 4 and the squeezing roller 2 5 is more precise, which effectively improves the shaping quality of the square tube 2.

[0042] Among them, the extension mechanism includes a motor 2 12 fixedly installed inside the squeezing roller 1 4, the output shaft of the motor 2 12 passes through the storage bin 10, and is fixedly connected to the threaded rod 13, the storage bin 10 is fixedly opened at one end of the squeezing roller 1 4, the threaded rod 13 is rotatably installed inside the storage bin 10, the threaded rod 13 and the extension block 8 are threadedly connected, and the extension block 8 and the fixed block 7 are fixedly connected.

[0043] The staff starts the motor 2 12, and the operation of the motor 2 12 drives the threaded rod 13 to rotate. The rotation of the threaded rod 13 drives the extension block 8 threadedly connected thereto to move. At this time, the extension block 8 is restricted by the storage bin 10, so that the extension block 8 begins to extend outward, and the outward movement of the extension block 8 causes the fixed block 7 to pull the connecting rod 9, further causing the connecting rod 9 to move outward along the connecting bin 11, thereby completing the adjustment of the spacing.

[0044] Among them, the lifting mechanism includes a fixed frame 14 fixedly installed on the top of the extrusion bin 1, a cylinder 15 is fixedly installed on the top of the fixed frame 14, and movable grooves 16 are fixedly opened on the front and rear sides of the fixed frame 14. The output shaft of the cylinder 15 passes through the bottom of the fixed frame 14 and is fixedly connected to the pressure plate 17, and the pressure plate 17 is movably installed inside the movable groove 16.

[0045] Among them, a fixed plate 18 is fixedly installed at the bottom of the pressing plate 17. There are two groups of fixed plates 18, which are located at the front and rear sides below the pressing plate 17. An extrusion shaping mechanism is rotatably installed between the two groups of fixed plates 18. A motor three 19 is fixedly installed at one end of the front fixed plate 18, and an extrusion roller one 4 is rotatably installed at the other end. The output shaft of the motor three 19 passes through the fixed plate 18 and is fixedly connected to the extrusion roller one 4. The internal movable sleeve of the rear fixed plate 18 is connected with a rotating rod 6.

[0046] The staff starts the cylinder 15, so that the cylinder 15 drives the pressing plate 17 to move. At this time, the pressing plate 17 moves downward along the movable groove 16 until the extrusion roller 1 4 and the extrusion roller 2 5 collide with the top of the square tube 2, thereby completing the adjustment of the extrusion shaping operation.

[0047] Among them, a square tube 2 is movably arranged between the two groups of extrusion shaping mechanisms, and the upper and lower groups of extrusion rollers 1 4 and extrusion rollers 2 5 are in conflict with the square tube 2.

[0048] The outer wall of the distance measuring rod 21 is fixedly engraved with a scale 22 for distance measurement.

[0049] The working principle and use process of this utility model:

[0050] When it is necessary to extrude and shape the square tube 2, the staff places the square tube 2 between the two groups of extrusion rollers 1 4 and 2 5, and starts motor 1 3 and motor 3 19 to make the extrusion rollers 1 4 and 2 5 start to rotate. The extrusion rollers 1 4 and 2 5 can extrude and shape the square tube 2 while transporting it. When the first batch of square tubes 2 are extruded and shaped, the size needs to be adjusted. At this time, the staff starts motor 2 12. The operation of motor 2 12 drives the threaded rod 13 to rotate. The rotation of the threaded rod 13 drives the extension block 8 threadedly connected to it to move. At this time, the extension block 8 is restricted by the storage bin 10, so that the extension block 8 begins to extend outward, and the outward movement of the extension block 8 causes the fixed block 7 to pull the connecting rod 9, further making the connecting rod 9 move along As the connecting bin 11 moves outward, the displacement of the fixed block 7 also pushes the squeezing roller 25 to move until the distance between the squeezing roller 14 and the squeezing roller 25 reaches a suitable distance. The staff then stops the motor 21, and then pushes the ranging rod 21 downward to move the ranging rod 21 downward along the bracket 20, and makes the roller 24 and the outer wall of the square tube 2 conflict with each other. At this time, the staff rotates the fastener 23 to fix the ranging rod 21. At this time, the staff can observe the height of the square tube 2 through the scale 22. When the measurement is completed, the staff starts the cylinder 15 to drive the pressure plate 17 to move. At this time, the pressure plate 17 moves downward along the movable groove 16 until the squeezing roller 14 and the squeezing roller 25 conflict with the top of the square tube 2, thereby completing the adjustment of the extrusion shaping operation.
