Description

Technical Field

[0001] This utility model relates to plate rolling machines, and in particular to an upper roller auxiliary support structure for plate rolling machines. Background Technology

[0002] A plate rolling machine is used to roll flat sheet metal into a cylindrical shape. The flat sheet metal is fed between upper and lower rollers for rolling. There are two lower rollers and one upper roller. The cylindrical sheet metal is fitted onto the upper roller at a symmetrical position corresponding to the center between the two lower rollers. Therefore, both ends of the lower rollers are directly rotatably connected to the machine frame, while the upper roller has only one end, with the other end left open so that the cylindrical sheet metal can be moved off the upper roller along its axis to complete the unloading process. Because the width of the sheet metal is generally relatively large, the length of the upper roller is also relatively large. Relying on only one end connected to the machine frame, the upper roller is unstable when rolling the sheet metal. Therefore, plate rolling machines are generally equipped with an upper roller auxiliary support structure to support and limit the upper roller. The upper roller auxiliary support structure generally includes: a mounting part for mounting with the plate rolling machine, a support arm hinged to the mounting part, and a hydraulic cylinder that drives the support arm to swing. When the support arm is vertical, the end of the upper roller enters the support hole of the support arm; when the support arm is tilted, it is lower than the upper roller and will not interfere with the movement of the cylindrical coiled plate along the axis of the upper roller from the upper roller. The support hole is inserted into / out of the end of the upper roller only by the swing of the support arm. The lower part of the upper roller end and the support hole are in contact, while the upper part needs to leave a gap for swinging. This provides a support effect, but the limiting effect is generally limited. Utility Model Content

[0034] Please see Figure 1 , Figure 2 and Figure 3 An auxiliary support structure for the upper roller of a plate rolling machine includes a first mounting part 1, a second mounting part 2, a support arm 3, a hydraulic cylinder 4, and a linear drive part 5.

[0035] The first mounting part 1 is used for fixed connection with the equipment frame of the plate rolling machine, and the upper roller auxiliary support structure is installed in the corresponding position of the equipment frame. More specifically, bolts are generally used to complete the fixed connection.

[0036] The second mounting part 2 is slidably connected to the first mounting part 1 along a horizontal first direction. More specifically, the first mounting part 1 may be fixedly provided with a guide rail 1a, and the bottom surface of the second mounting part 2 has a groove 2a that matches the guide rail 1a.

[0037] The support arm 3 has a support hole 3a at its upper position, which is used to support the end of the upper roller. The support arm 3 is hinged to the second mounting part 2 at its lower position.

[0038] Hydraulic cylinder 4 is used to drive the support arm 3 to swing. More specifically, the cylinder body of hydraulic cylinder 4 is hinged to the second mounting part 2, and the piston rod is hinged to the support arm 3. Based on the hinge positions of the support arm 3 and the second mounting part 2, two hinge positions are designed so that the support hole 3a of the support arm 3 can switch between the following two states: a support state where the axis of the support hole 3a is parallel to the first direction, and a feeding state where the axis of the support hole 3a is inclined. That is, in the support state, the support arm 3 is vertical, and the support hole 3a corresponds to the end of the upper roller; in the feeding state, the support arm 3 is inclined, lower than the upper roller, and will not interfere with the movement of the cylindrical coil along the axis of the upper roller from the upper roller.

[0039] Please see Figure 2In some embodiments, the second mounting portion 2 is L-shaped in the vertical plane, and the hinge point of the support arm 3 in the second mounting portion 2 is higher than the hinge point of the hydraulic cylinder 4 in the second mounting portion 2. That is, the hinge position of the support arm 3 and the second mounting portion 2 (marked as the first hinge position) is in the vertical portion 2-1 of the second mounting portion 2, and the hinge position of the cylinder body of the hydraulic cylinder 4 and the second mounting portion 2 (marked as the second hinge position) is in the horizontal portion 2-2 of the second mounting portion 2. The vertical portion 2-1 and the horizontal portion 2-2 can be detachably connected.

[0040] The hinge position of the cylinder body of the hydraulic cylinder 4 and the support arm 3 (marked as the third hinge position) can be designed relatively easily. More specifically, when the support arm 3 is vertical, the distance between the first hinge position and the second hinge position projected onto the first direction is greater than the distance between the first hinge position and the third hinge position projected onto the vertical direction.

[0041] Please see Figure 2 and Figure 3 In some embodiments, the first mounting portion 1 is T-shaped in the horizontal plane, including a longitudinal portion 1-1 for sliding connection with the second mounting portion 2, and a transverse portion 1-2 perpendicular to the longitudinal portion 1-1. That is, the longitudinal portion 1-1 is along a first direction, and the transverse portion 1-2 is along a direction perpendicular to the first direction and also horizontal, which is set as the second direction. Both sides of the second mounting portion 2 extend beyond the transverse portion 1-2, and are respectively used for hinged connection of the hydraulic cylinder 4 and the support arm 3.

[0042] Because the support hole 3a is used to support the end of the upper roller, the connection between the first mounting part 1 and the equipment frame of the plate rolling machine needs to be relatively stable. The first mounting part 1 is T-shaped in the horizontal plane and can be fixedly connected to the equipment frame by the transverse part 1-2. The transverse part 1-2 can have a suitable length and be provided with a corresponding number of mounting holes. Bolts pass through the transverse part 1-2 and are then threaded to the equipment frame.

[0043] When the upper roller auxiliary support structure is installed on the plate rolling machine, the support arm 3 is vertical. First, the support hole 3a is fitted into the end of the upper roller, and then bolts are used to fix and connect the transverse part 1-2 and the equipment frame of the plate rolling machine. Tolerances mean that the mounting holes of the transverse part 1-2 may not align with the threaded holes of the equipment frame. The compensation measure is generally to design the diameter of the mounting holes to be larger, allowing the bolts to move slightly in the second direction and vertical direction within the mounting holes, thus aligning with the threaded holes. Therefore, there is likely a gap between the upper inner wall 7a1 of the mounting hole and the bolts. The fixed connection between the first mounting part 1 and the equipment frame relies on bolts for tightening. Under the pressure of the upper roller end, the upper roller auxiliary support structure may shift downwards, meaning the stability of the connection between the first mounting part 1 and the equipment frame needs to be improved.

[0044] Please see Figure 5 , Figure 6 and Figure 7 In some embodiments, furthermore, a plurality of triangular support frames 7 are fixedly connected to the bottom surface of the transverse portion 1-2, and the triangular support frames 7 can be adjusted in a fixed position on the bottom surface of the first mounting portion 1 along the second direction. More specifically, the bottom surface of the transverse portion 1-2 has a T-slot 1b, the horizontal plate of the triangular support frame 7 is attached to the bottom surface of the first mounting portion 1 and has mounting holes, and fasteners are used to connect the two, with nuts located in the wider portion of the T-slot 1b and restricted from rotation, and bolts passing through the triangular support frame 7 and threadedly connected to the nuts.

[0045] The vertical plate of the triangular support frame 7 also has a mounting groove 7a for mounting with the plate rolling machine, and the upper inner wall 7a1 of the mounting groove 7a is inclined. That is to say, the bolts no longer pass through the horizontal part 1-2, but pass through the triangular support frame 7 and are threaded to the equipment frame, and the first mounting part 1 and the equipment frame of the plate rolling machine are fixedly connected by the triangular support frame 7.

[0046] The support arm 3 is vertical. First, the support hole 3a is fitted into the end of the upper roller. Then, the triangular support frame 7 is moved so that the wider side of the mounting groove 7a aligns with the threaded hole of the equipment frame. The bolt then passes through the mounting groove 7a, threadedly connecting to the equipment frame but not tightened. Next, the triangular support frame 7 is moved so that the upper inner wall 7a1 of the mounting groove 7a abuts against the bolt. Finally, the bolt is tightened to fix the connection between the triangular support frame 7 and the equipment frame, and between the triangular support frame 7 and the transverse parts 1-2. Additionally, the inclined plate of the triangular support frame 7 can have holes 7b for inserting an internal hexagonal socket along the vertical / first direction to mate with two bolts. The addition of the triangular support frame 7 completes the tolerance compensation measures and eliminates the gap between the upper inner wall 7a1 of the mounting groove 7a and the bolt, further improving the stability of the connection between the equipment frames.

[0047] Please see Figure 1 The linear drive unit 5 is used to drive the second mounting unit 2 to move so that the support hole 3a in the supported state can be inserted into / out of the end of the upper roller.

[0048] After the upper roller auxiliary support structure is installed on the equipment frame, the unloading process is as follows: the linear drive unit 5 drives the second mounting unit 2 to move, and the support hole 3a disengages from the end of the upper roller; the hydraulic cylinder 4 drives the support arm 3 to swing, so that the support hole 3a switches from the support state to the unloading state; the cylindrical rolled plate is moved out of the upper roller along the axis of the upper roller. The preparation process before the rolled plate is processed is as follows: the hydraulic cylinder 4 drives the support arm 3 to swing, so that the support hole 3a switches from the unloading state to the support state; the linear drive unit 5 drives the second mounting unit 2 to move, and the support hole 3a fits into the end of the upper roller.

[0049] Please see Figure 3In some embodiments, in conjunction with the above-described embodiment where "the first mounting portion 1 is T-shaped in the horizontal plane," the linear drive unit 5 includes a bidirectional lead screw module 5-1 and two connecting bars 5-2. The bidirectional lead screw module 5-1 is mounted on the transverse portion 1-2 and includes a bidirectional lead screw 5-11 rotatably connected to the transverse portion 1-2, two sliders 5-12 slidably connected to the transverse portion 1-2 along a second direction and fixedly connected to the lead screw nut, and a motor 5-13 that drives the bidirectional lead screw 5-11 to rotate. The transverse portion 1-2 has a through-groove 2b through which the bidirectional lead screw 5-11 passes. The through-groove 2b has a suitable length in the first direction and will not interfere with the movement of the second mounting portion 2 relative to the first mounting portion 1. One end of each of the two connecting bars 5-2 is hinged to one of the two sliders 5-12, and the other end is hinged to the second mounting portion 2.

[0050] Please see Figure 4 In some embodiments, the upper roller auxiliary support structure also includes a protective barrier 6. The protective barrier 6 is U-shaped and fixedly connected to the equipment frame, enclosing the support arm 3 to prevent the support arm 3 from being touched by people during swinging, thereby improving safety.
