Description

Technical Field

[0001] The invention relates to a worm plate numerical control rounding machine. Background Art

[0002] The fan casing is composed of a volute and side plates on both sides of the volute. The volute rolling equipment is a device that rolls the straight volute into a volute-shaped volute. The volute is generally composed of four sections of geometric shapes, namely a straight line part and three arc parts.

[0003] The traditional equipment for rolling the worm plate is a three-roller rolling machine, but the three-roller rolling machine is limited by its own structure. If a large worm plate is to be rolled, four or five workers are needed to hold the worm plate and wait for the rolling to be completed before lifting the worm plate out. Therefore, a lot of manpower and material resources are required to complete the rolling work. The rolling efficiency is extremely low. In the process of rolling the worm plate, the grooves on both sides of the worm plate used for assembly with the side plates are easily squeezed and deformed, and it is difficult to ensure the accuracy of the grooves after the worm plate is rolled, resulting in the grooves failing to meet the size requirements. When the groove accuracy is not enough, the rolled worm plate is difficult to assemble with the side plates, resulting in difficulty in assembly work and affecting assembly efficiency.

[0039] The pulley assembly includes a slide 75 arranged in the lifting channel 58; a plurality of slide rollers 76 matching the lifting groove 74 are arranged on the left and right sides of the slide 75; symmetrical lifting ears 77 are arranged on the upper and lower sides of the left wall of the slide 75; the two ends of the third chain are connected to the lifting ears 77 on the upper and lower sides; the lifting rod 8 is arranged on the right side wall of the slide 75.

[0040] The method of use of the present invention is as follows:

[0041] Before the straight volute needs to be rolled into a volute-shaped volute, the position of the support piece 21 can be roughly adjusted according to the width of the straight volute, so that the support piece 21 is located near the slots on both sides of the straight volute. When the position of the support piece 21 needs to be roughly adjusted, the first linear slider 13 can be directly slid to drive the first cylinder mounting seat 16 to move stably along the trajectory of the first guide rail 4, and the support piece 21 moves accordingly. When the support piece 21 moves to the actual required position, the screw can be screwed into the locking screw hole 15 on the locking block 14 to press the screw against the first guide rail 4, so that the locking block 14 can achieve a locking effect. At this moment, the position of the first linear slider 13 is fixed, and the position of the first cylinder 17 arranged on the first cylinder mounting seat 16 is fixed accordingly, and the approximate position of the support piece 21 is fixed. Then the first cylinder 17 can be used to fine-tune the position of the support piece 21. When the first cylinder 17 is started, the piston rod of the first cylinder 17 will drive the sliding member 20 to move along the track of the slide groove 19 on the upper surface of the slide groove fixing block 18, and the support piece 21 arranged at the rear end of the sliding member 20 will move accordingly. When the support pieces 21 on the left and right sides are just in the position where they can be inserted into the slots on both sides of the straight volute, the first cylinder 17 stops running and the final position of the support piece 21 is fixed.

[0042] When it is necessary to round the straight worm plate into a worm-shaped worm plate, the first motor 35 can be started. When the first motor 35 is running, the motor shaft of the first motor 35 will drive the first driving sprocket 36 to rotate. At this time, the first driving sprocket 36 will drive the first driven sprocket 33 to rotate through the first chain. When the first driven sprocket 33 rotates, the lower roller shaft 31 rotates accordingly, and the driving gear 39 on the right part of the lower roller shaft 31 is meshed with the driven gear 40 on the right part of the upper roller shaft 28. Therefore, when the lower roller shaft 31 rotates clockwise, the upper roller shaft 28 rotates counterclockwise. When the straight volute is between the upper roller 28 and the lower roller 31, the rotational force of the upper roller 28 and the rotational force of the lower roller 31 will drive the straight volute to be transported stably to the rear. In order to ensure that the distance between the upper roller 28 and the lower roller 31 can adapt to the thickness of the straight volute, the height of the upper roller 28 can be adjusted by the second cylinder 23. When the second cylinder 23 is started, the piston rod of the second cylinder 23 will drive the upper bearing seat 27 to move up and down stably along the trajectory of the adjustment groove 26, thereby realizing the change of the distance between the upper roller 28 and the lower roller 31.

[0043] When the rounding work begins, the front end of the straight worm plate will pass through the top of the roller shaft 10, the gap between the upper roller shaft 28 and the lower roller shaft 31, and the top of the moving roller shaft 55 in sequence. At this moment, the lower surface of the straight worm plate contacts the upper surface of the roller shaft 10, the upper surface of the lower roller shaft 31, and the upper surface of the moving roller shaft 55. The support piece 21 is in the grooves on the left and right sides of the straight worm plate. As the upper roller shaft 28 and the lower roller shaft 31 rotate synchronously, the straight worm plate will be synchronously transported backwards when being rolled by the middle wheel 30 on the upper roller shaft 28, and the side rollers 38 on the left and right sides of the upper roller shaft 28 can effectively assist in rolling, and a clearance ring 37 is provided on the side of the side roller 38 adjacent to the support piece 21. The outer diameter of the clearance ring 37 is smaller than the outer diameter of the side roller, and the position of the clearance ring 37 just corresponds to the position of the groove on the side of the worm plate. The existence of the clearance ring 37 can make the side rolling The wheel will not roll on the side of the snail plate, thereby avoiding the situation where the side roller 38 rolls on the side of the snail plate and causes the groove on the side of the snail plate to deform. Due to the different sizes of snail plates, the rolling position requirements for the intermediate wheel 30 and the side roller 38 are also different. At this time, the position of the intermediate wheel 30 and the side roller 38 can be adjusted according to actual needs. In order to facilitate the adjustment of the position of the intermediate wheel 30 and the side roller 38, adjustment screw holes that are connected to their respective internal spaces can be provided on the outer walls of the intermediate wheel 30 and the side roller 38. An adjustment screw that presses against the outer wall of the upper roller shaft 28 is threaded in the adjustment screw hole. The position of the intermediate wheel 30 and the side roller can be adjusted by loosening the adjustment screw. Tighten the adjustment screw again so that the adjustment screw presses against the outer wall of the upper roller shaft 28 again, and the position of the intermediate wheel 30 and the side roller 38 after the position adjustment is completed can be fixed.

[0044] The support piece 21 is stuck in the groove on the side of the worm plate when the worm plate is rolled. The support piece 21 can cooperate with the give way ring 37 to further effectively prevent the grooves on the left and right sides of the straight worm plate from being squeezed and deformed when the straight worm plate is rolled, thereby ensuring that the straight worm plate can be quickly assembled with the grooves on the left and right sides and the side plates after being rolled into a worm-shaped worm plate, and the retaining rings 12 on the left and right sides of the roller shaft 10 can play a limiting role, effectively preventing the straight worm plate from lateral deviation during the rolling process, so that the straight worm plate is always in a stable conveying state.

[0045] The height of the moving roller 55 determines the curvature of the straight worm plate when it is rounded into a worm plate, but the position of the moving roller 55 is always higher than the position of the upper roller 28. When the front end of the straight worm plate is transported to the position of the moving roller 55 by the upper roller 28 and the lower roller 31, the front end of the straight worm plate will bend upward along the outer wall of the moving roller 55, so that the straight worm plate gradually forms an arc and begins to transform into a snail-shaped worm plate. As more and more parts of the straight worm plate are tilted in an arc, a staff member can hold the lower surface of the tilted part with his hand to make it continue to move upward stably. The straight volute is bent, and the bent part of the straight volute will go around the lifting rod 8 from the back to the front, and the lifting rod 8 will directly support the original upper surface of the straight volute, that is, the inner wall of the volute at this moment. As the lifting rod 8 supports the volute, the labor intensity of the staff when supporting the volute by hand can be effectively reduced, thereby effectively reducing manpower. The work that originally required four or five people to support the volute by hand can be completed by only one person. When the volute completely passes through the gap between the upper roller shaft 28 and the lower roller shaft 31, the volute is completely formed. At this time, only one more staff member is needed to cooperate to remove the volute from the lifting rod 8.

[0046] When the height of the movable roller 55 needs to be adjusted, the second motor 52 can be started. At this time, the motor shaft of the second motor 52 will drive the right lead screw 49 to rotate through the coupling 53. When the right lead screw 49 rotates, the longitudinal bevel gear 50 on the right lead screw 49 will mesh with the transverse bevel gear 46 on the right end of the transmission shaft 44, thereby driving the transmission shaft 44 to rotate. When the transmission shaft 44 rotates, the transverse bevel gear 46 at the left end of the transmission shaft 44 will drive the left lead screw 49 to rotate by meshing with the longitudinal bevel gear 50 on the left lead screw 49, thereby realizing the synchronous rotation of the lead screws 49 on the left and right sides. Since the lead screw 49 is covered with a lead screw nut 48 matching it, The lead screw nut 48 is fixed on the nut seat 47, and the nut seat 47 is fixed on the second linear slider 42. The second linear slider 42 is arranged on the second guide rail 41 that matches it. Therefore, under the restriction of the second guide rail 41, the force of the lead screw 49's rotation will eventually be converted into a force for the lead screw nut 48 to move up and down. When the lead screw nut 48 moves up and down, the second linear slider 42 moves up and down accordingly. The side walls of the second linear sliders 42 on the left and right sides that are opposite to each other are provided with a fifth bearing seat 54. The moving roller 55 is mounted between the fifth bearing seats 54 on the left and right sides. Therefore, the moving roller 55 will move up and down along the second linear slider 42, thereby realizing the height adjustment of the moving roller 55.

[0047] In actual use, the height of the lifting rod 8 can be adjusted. Therefore, even if the size of the worm plate is different or the bending angle of the worm plate is different, the lifting rod 8 can always lift the worm plate during the rolling process. When the height of the lifting rod 8 needs to be adjusted, the third motor 66 can be started. At this time, the motor shaft of the third motor 66 will drive the second active sprocket 67 to rotate, and the second active sprocket 67 is connected to the second driven sprocket 63 through the second chain. Therefore, when the second active sprocket 67 rotates, the second driven sprocket 63 will drive the lower chain shaft 61 to rotate. When the lower chain shaft 61 rotates, the third driven sprocket 64 rotates accordingly, and the third driven sprocket 64 is connected to the fourth driven sprocket 72 through the third chain. When the third driven sprocket 64 rotates , the fourth driven sprocket 72 rotates accordingly. At the same time, the third chain forms a closed loop, which rotates and conveys around the third driven sprocket 64 and the fourth driven sprocket 72, and the two ends of the third chain are fixed to the upper and lower ends of the slide 75 through the lifting ears 77. Therefore, when the third chain is rotated and conveyed, the slide 75 will move up and down under the action of the third chain, thereby driving the lifting rod 8 on the right side wall of the slide 75 to move up and down, so as to adjust the height of the lifting rod 8. After the height adjustment of the lifting rod 8 is completed, the third motor 66 can be turned off. The lifting ear 77 is a common structure on the market. The screws on the lifting ear 77 can be used to effectively fix the ends of the third chain to ensure the stability of the two ends of the third chain when connected to the upper and lower ends of the slide 75.

[0048] When the slide 75 moves, the slide roller 76 will roll along the track of the lifting groove 74. The existence of the slide roller 76 can not only guide the slide 75 to ensure the stability of the slide 75 when it moves up and down, but also improve the smoothness of the slide 75 when it moves up and down.

[0049] The worm plate of the present invention is rolled by the lifting rod 8 of the lifting device 7, thereby effectively reducing the labor intensity of the staff who hold the worm plate by hand. The work that originally required four or five staff members to complete can be completed by one person. After the worm plate is completely formed, another staff member only needs to cooperate to remove the worm plate from the lifting rod 8, thereby effectively reducing manpower and material resources and avoiding waste of manpower and material resources. The whole rolling process of the worm plate is automatically completed under the conveyance of the upper roller 28 and the lower roller 31, and the high rolling efficiency can be always maintained. The support sheet 21 of the support structure 5 can always be stuck in the grooves on the left and right sides of the worm plate when the upper roller 28 and the lower roller 31 roll the worm plate, so as to play the effect of supporting the grooves, avoiding the situation that the grooves on the left and right sides of the worm plate are squeezed during the rolling process, resulting in the situation that the accuracy cannot be guaranteed, and effectively ensuring the accuracy of the grooves on the left and right sides of the worm plate, thereby ensuring that the rolled worm plate can be quickly assembled with the side plate, thereby improving the assembly efficiency.
