Description

Technical Field

[0001] This utility model relates to the field of tube rolling machine technology, and in particular to a tube rolling machine. Background Technology

[0002] A tube rolling machine is a device that uses work rollers to bend sheet metal into various shapes, such as cylindrical and conical parts. It is a very important processing equipment. The working principle of a tube rolling machine is that the work rollers move under the action of external forces such as hydraulic pressure and mechanical force, thereby bending or rolling the sheet metal into shape. Depending on the rotation and position changes of the work rollers of different shapes, elliptical, arc-shaped, and cylindrical parts can be processed.

[0003] A search revealed a Chinese utility model patent with authorization announcement number CN204700093U, which describes a tube winding machine. The machine includes: a support frame, a motor, a reducer, an active extrusion roller, a driven extrusion roller, a lead screw, a lower pressure seat, a winding roller, and a handle. The input shaft of the reducer is fixedly connected to the output shaft of the motor. One end of the active extrusion roller is fixedly connected to the output shaft of the reducer. The driven extrusion roller is horizontally mounted on the support frame via bearings. A lead screw is vertically mounted at each end of the support frame, and a lower pressure seat is mounted at the lower end of each lead screw. The two ends of the winding roller are mounted on the two lower pressure seats via bearings. This design offers advantages such as ease of use and cost savings.

[0004] However, the prior art only considered how to make the round tube, but did not consider how to remove the round tube. After the prior art rolls the sheet into a round tube, the lower pressure seat needs to be manually separated from the winding roller, and then the bracket needs to be opened so that the round tube outside the winding roller can be detached from the material. This process is cumbersome, which not only reduces production efficiency, but also increases the labor intensity of operators. In view of this, this application proposes a tube rolling machine based on the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a tube rolling machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A tube winding machine includes a base frame, a worktable fixedly mounted on the top of the base frame, two sets of support components arranged on the upper surface of the worktable, two push rollers arranged between the support components, a transmission component arranged between the push rollers, and a pressure roller arranged above the two push rollers.

[0008] The support assembly includes a fixed plate fixedly installed on the upper surface of the workbench, connecting plates fixedly installed at both ends of the fixed plate, a first rotating rod rotatably installed on the inner side of the connecting plate, a flap fixedly installed on the outer side of the first rotating rod, connecting sleeves rotatably connected to both ends of the pressure roller, two symmetrical support plates fixedly installed on the upper surface of the connecting sleeves, a second rotating rod rotatably installed on the support plates, a lifting rod fixedly installed at one end of the pressure roller, and a flipping assembly provided on one side of the flap.

[0009] The flipping assembly includes a first hydraulic cylinder, a support frame is fixedly installed on the base frame, a first mounting seat is fixedly installed on one side of the support frame, a second mounting seat is fixedly installed on one side of the flipping plate, and the first hydraulic cylinder is rotatably installed between the first mounting seat and the second mounting seat.

[0010] Furthermore, the support assembly also includes a support base fixedly mounted on the upper surface of the fixed plate. The support base has two mounting holes. The support base is rotatably connected to the first rotating rod. The push roller is rotatably mounted between the mounting holes on different support bases.

[0011] Furthermore, the transmission assembly includes a motor fixedly mounted on the upper surface of the workbench, a reducer fixedly mounted on the output end of the motor, a drive gear fixedly mounted on the output end of the reducer, a driven gear fixedly mounted on one end of each push roller, the drive gear meshing with one of the driven gears, and a transmission gear rotatably mounted on one side of one of the support seats, the transmission gear meshing with the driven gear.

[0012] Furthermore, an installation plate is fixedly installed between the flaps, and a second hydraulic cylinder is fixedly installed on the lower surface of the installation plate. A connector is fixedly installed at the output end of the second hydraulic cylinder, and the connector is sleeved on the outside of the second rotating rod.

[0013] Furthermore, a bracket is fixedly installed on the upper surface of the workbench, a screw is threaded to the top of the bracket, a rocker arm is fixedly installed at the top of the screw, and a spherical roller is fixedly installed at the bottom of the screw, with the bottom of the spherical roller abutting against the upper surface of the lifting rod.

[0014] Furthermore, the centers of the two driven gears are symmetrically arranged above the centers of the transmission gears on both sides.

[0015] Furthermore, both the pressure roller and the push roller are made of quenched alloy tool steel.

[0016] Furthermore, the radius of the pressure roller is smaller than that of the push roller.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1. This utility model, by setting up a first hydraulic cylinder, a flap, a first rotating rod, a lifting rod, a connecting sleeve, and a second rotating rod, inserts the sheet metal between the pressure roller and the push roller, rolls it into a round tube, and then starts the first hydraulic cylinder. The output end of the first hydraulic cylinder retracts and drives the flap to rotate 90 degrees around the axis of the first rotating rod. At this time, one end of the pressure roller is in an empty state and is not connected to any object. Then, the lifting rod is pressed down, and the lifting rod drives the other end of the pressure roller to rotate at a small angle around the axis of the second rotating rod. At this time, one end of the pressure roller is raised, and the rolled round tube is not subjected to the downward pressure of the pressure roller, so the round tube can be easily taken out.

[0019] 2. This utility model, by setting up a lifting rod, a spherical roller, and a ball-shaped roller, allows the lifting rod to return to a horizontal state under the constraint of the ball-shaped roller after it is pressed down, so that there will be no tilting. The ball-shaped roller can also rotate along with the pressure roller. At the same time, turning the rocker arm can drive the screw to rotate, so that the height of the ball-shaped roller can be adjusted. This allows it to remain in close contact with the upper surface of the lifting rod after the height of the pressure roller is adjusted.

[0020] 3. By setting a second hydraulic cylinder, a connecting sleeve, and a pressure roller, this utility model can change the distance between the pressure roller and the push roller by moving the connecting sleeve and the pressure roller in the vertical direction before rolling the round tube. This can adapt to the rolling requirements of plates of different thicknesses without having to change to different tube rolling machines according to different plate thicknesses.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Reference Figure 1-4 A tube rolling machine includes a base frame 1, a worktable 2 fixedly installed at the top of the base frame 1, two sets of support components are provided on the upper surface of the worktable 2, two push rollers 3 are provided between the support components, a transmission component is provided between the push rollers 3, and a pressure roller 4 is provided above the two push rollers 3.

[0031] The support assembly includes a fixed plate 5 fixedly installed on the upper surface of the workbench 2. Connecting plates 6 are fixedly installed at both ends of the fixed plate 5. A first rotating rod 7 is rotatably installed on the inner side of the connecting plate 6. A flip plate 8 is fixedly installed on the outer side of the first rotating rod 7. Connecting sleeves 9 are rotatably connected to both ends of the pressure roller 4. Two symmetrical support plates 10 are fixedly installed on the upper surface of the connecting sleeves 9. A second rotating rod 11 is rotatably installed on the support plates 10. A lifting rod 12 is fixedly installed at one end of the pressure roller 4. A flipping assembly is provided on one side of the flip plate 8.

[0032] The flipping assembly includes a first hydraulic cylinder 13, a support frame 14 is fixedly installed on the base frame 1, a first mounting seat 15 is fixedly installed on one side of the support frame 14, a second mounting seat 16 is fixedly installed on one side of the flip plate 8, and the first hydraulic cylinder 13 is rotatably installed between the first mounting seat 15 and the second mounting seat 16.

[0033] Insert the sheet material between the pressure roller 4 and the push roller 3, and roll it into a round tube. Then, start the first hydraulic cylinder 13. The output end of the first hydraulic cylinder 13 retracts and drives the flip plate 8 to rotate 90 degrees around the axis of the first rotating rod 7. At this time, one end of the pressure roller 4 is in an empty state and is not connected to any object. Then, press down the lifting rod 12. The lifting rod 12 drives the other end of the pressure roller 4 to rotate at a small angle around the axis of the second rotating rod 11. At this time, one end of the pressure roller 4 is raised, and the rolled round tube is not under the downward pressure of the pressure roller 4, so the round tube can be easily taken out.

[0034] Reference Figure 1 , Figure 5 Specifically: the support assembly also includes a support base 17 fixedly installed on the upper surface of the fixed plate 5. The support base 17 is provided with two mounting holes 18. The support base 17 is rotatably connected to the first rotating rod 7. The push roller 3 is rotatably installed between the mounting holes 18 on different support bases 17.

[0035] Reference Figure 1 , Figure 7 Specifically: the transmission assembly includes a motor 19 fixedly mounted on the upper surface of the workbench 2, a reducer 20 fixedly mounted on the output end of the motor 19, a drive gear 21 fixedly mounted on the output end of the reducer 20, a driven gear 22 fixedly mounted on one end of each push roller 3, the drive gear 21 meshing with one of the driven gears 22, and a transmission gear 23 rotatably mounted on one side of one of the support seats 17, the transmission gear 23 meshing with both the driven gear 22;

[0036] After the sheet material is inserted between the pressure roller 4 and the push roller 3, the motor 19 is started. The motor 19 drives the reducer 20 to work. The reducer 20 drives the drive gear 21 to rotate. The drive gear 21 drives one of the driven gears 22 to rotate. Under the transmission of the transmission gear 23, the two driven gears 22 rotate in the same direction, thereby rolling the sheet material into a round tube.

[0037] Reference Figure 1 , Figure 5 Specifically: an mounting plate 24 is fixedly installed between the flip plates 8, and a second hydraulic cylinder 25 is fixedly installed on the lower surface of the mounting plate 24. A connector 26 is fixedly installed at the output end of the second hydraulic cylinder 25. The connector 26 is sleeved outside the second rotating rod 11. Before rolling the round tube, the second hydraulic cylinder 25 drives the connecting sleeve 9 and the pressure roller 4 to move in the vertical direction, which can change the distance between the pressure roller 4 and the push roller 3, thereby adapting to the rolling requirements of different thickness plates, without having to change different tube rolling machines according to different thickness plates.

[0038] Reference Figure 1 , Figure 6Specifically: a bracket 27 is fixedly installed on the upper surface of the workbench 2, a screw 28 is threadedly connected to the top of the bracket 27, a rocker arm 29 is fixedly installed on the top of the screw 28, and a spherical roller 30 is fixedly installed at the bottom of the screw 28, with the bottom of the spherical roller 30 abutting against the upper surface of the lifting rod 12;

[0039] After the lifting rod 12 is pressed down, the next tube winding operation is required. At this time, the lifting rod 12 is released, and the lifting rod 12 returns to the horizontal state under the restriction of the spherical roller 30 without tilting. The spherical roller 30 can also rotate along with the rotation of the pressure roller 4. At the same time, rotating the rocker arm 29 can drive the screw 28 to rotate, so that the height of the spherical roller 30 can be adjusted. This allows it to remain in close contact with the upper surface of the lifting rod 12 after the height of the pressure roller 4 is adjusted.

[0040] Reference Figure 7 Specifically, the centers of the two driven gears 22 are symmetrically arranged above the centers of the transmission gear 23 on both sides.

[0041] Reference Figure 1 Specifically: the pressure roller 4 and the push roller 3 are both made of quenched alloy tool steel, which has high hardness, good wear resistance and high compressive strength.

[0042] Reference Figure 1 Specifically: the radius of the pressure roller 4 is smaller than that of the push roller 3. The smaller radius pressure roller has a smaller contact area with the sheet material, resulting in more concentrated pressure and more precise control over the bending position and angle, making it suitable for high-precision or complex curvature forming.

[0043] Working principle: The sheet material is inserted between the pressure roller 4 and the push roller 3 and rolled into a round tube. Then, the first hydraulic cylinder 13 is started. The output end of the first hydraulic cylinder 13 is retracted and drives the flip plate 8 to rotate 90 degrees around the axis of the first rotating rod 7. At this time, one end of the pressure roller 4 is in an empty state and is not connected to any object. Then, the lifting rod 12 is pressed down. The lifting rod 12 drives the other end of the pressure roller 4 to rotate at a small angle around the axis of the second rotating rod 11. At this time, one end of the pressure roller 4 is raised. The rolled round tube is not under the downward pressure of the pressure roller 4, so the round tube can be easily taken out.

[0044] Before rolling the round tube, the connecting sleeve 9 and the pressure roller 4 are moved vertically by the second hydraulic cylinder 25, which can change the distance between the pressure roller 4 and the push roller 3, so as to adapt to the rolling requirements of different thickness plates, without having to change different tube rolling machines according to different thickness plates.

[0045] After the sheet is inserted between the pressure roller 4 and the push roller 3, the motor 19 is started. The motor 19 drives the reducer 20 to work. The reducer 20 drives the drive gear 21 to rotate. The drive gear 21 drives one of the driven gears 22 to rotate. Under the transmission of the transmission gear 23, the two driven gears 22 rotate in the same direction, thereby rolling the sheet into a round tube.

[0046] After the lifting rod 12 is pressed down, the next tube winding operation is required. At this time, the lifting rod 12 is released, and the lifting rod 12 returns to the horizontal state under the restriction of the spherical roller 30 without tilting. The spherical roller 30 can also rotate along with the rotation of the pressure roller 4. At the same time, rotating the rocker arm 29 can drive the screw 28 to rotate, so that the height of the spherical roller 30 can be adjusted. This allows it to remain in close contact with the upper surface of the lifting rod 12 after the height of the pressure roller 4 is adjusted.
