Description

Technical Field

[0001] The utility model relates to an anti-collision structure of a rib-pressing switching gear and belongs to the technical field of profile forming devices. Background Art

[0002] Profiles are objects with a certain geometric shape made from iron or steel and other materials with a certain strength and toughness through rolling, extrusion, casting and other processes; profiles can be used alone or further processed into other manufactured products, and are often used in building structures and manufacturing and installation.

[0003] C-shaped steel and sigma-shaped steel are common profiles, which play a pivotal role in the field of construction engineering or equipment manufacturing. At present, C-shaped steel and sigma-shaped steel are processed by C / sigma forming machines during the production process; in the process of processing C-shaped steel and sigma-shaped steel, the traditional C / sigma forming machine needs to control the lower rib roller group to move appropriately according to the type of steel being processed, that is, when the lower rib roller group and the upper rib roller group are in a close state, sigma-shaped steel can be processed, and when the lower rib roller group and the upper rib roller group are separated, C-shaped steel can be processed. When the lower beading roller group moves downward again, the corresponding gears will also move downward. At this time, the gears corresponding to the lower beading roller group and the upper pressing roller group will separate and will not rotate synchronously. When the lower beading roller group and the upper pressing roller group become close to each other again, the gears corresponding to the lower beading roller group and the upper pressing roller group will easily have tooth top to tooth top phenomenon during the re-engagement process, resulting in tooth collision, which will damage the gears and affect the subsequent processing.

[0033] The second beading roller group 3 is arranged below the first beading roller group 2, and the second beading roller group 3 includes a second mounting plate 301, and the second mounting plate 301 is movably arranged inside the gantry 1, and the second mounting plate 301 can move up and down inside the gantry 1, and the second beading shaft 303 is rotatably connected to the second mounting plate 301 by setting a second beading bearing 302, and a second beading roller 304 is arranged on one side end of the second beading shaft 303, and the second beading roller 304 is arranged on the outer side of the gantry 1 and is arranged on the same side as the first beading roller 201, and the second gear 6 is keyed to the other side end of the second beading roller 304, and the second gear 6 can be meshed with the first gear 5;

[0034] The adjusting component 4 is used to drive the second beading roller group 3 to move up and down on the gantry 1. The adjusting component 4 includes an adjusting motor 41 arranged on the top of the gantry 1. Reducers 42 are provided on both sides of the adjusting motor 41. The reducers 42 on both sides are also arranged on the top of the gantry 1. The input ends of the reducers 42 on both sides are connected to the electric spindle of the adjusting motor 41 through the transmission shaft. The output ends of the reducers 42 on both sides are provided with adjusting screw rods 43 that are vertically downwardly inserted into the gantry 1. The adjusting screw rods 43 on both sides are rotatably connected to the gantry 1 so as to be able to perform the required rotation in the gantry 1. Adjusting nuts 44 are threadedly connected to the adjusting screw rods 43 on both sides, and the adjusting nuts 44 on both sides are fixedly connected to the second mounting plate 301.

[0035] Through the above-mentioned settings, when processing C-shaped steel and sigma-shaped steel, according to the needs, the adjustment motor 41 is controlled to start working. The adjustment motor 41 can drive the adjustment screws 43 on both sides to rotate through the reducers 42 on both sides, so that the adjustment nuts 44 on both sides move up and down on the corresponding adjustment screws 43, thereby driving the second mounting plate 301 to move up and down in the gantry 1 to make the second ribbed roller 304 and the second gear 6 move up and down accordingly, so as to adapt to the processing of C-shaped steel and sigma-shaped steel. It should be noted that when processing C-shaped steel, the second gear 6 needs to move downward to form a separation state with the first gear 5, and when processing sigma-shaped steel, the second gear 6 needs to move upward to form a meshing state with the first gear 5.

[0036] In order to avoid the occurrence of tooth collision when the second gear 6 moves upward and forms a meshing state with the first gear 5, in this embodiment, the first gear 5 is also key-connected with a first connecting shaft 7, and the first connecting shaft 7 is sequentially provided with a sliding clutch 8, a fixed clutch 9 and a first sprocket 10 in a direction away from the first gear 5, wherein the sliding clutch 8 is connected to the first connecting shaft 7 by a sliding key connection, that is, the sliding clutch 8 can drive the first connecting shaft 7 to rotate when rotating, and the sliding clutch 8 can also be within the range allowed by the sliding key slot on the first connecting shaft 7, the fixed clutch 9 and the sliding clutch 8 are matched, when the fixed clutch 9 and the sliding clutch 8 are closed, the fixed clutch 9 can drive the sliding clutch 8 to move, when the fixed clutch 9 and the sliding clutch 8 are separated, the fixed clutch 9 cannot drive the sliding clutch 8 to move, the fixed clutch 9 and the first sprocket 10 are fixedly connected together, and the fixed clutch 9 and the first sprocket 10 are connected to the first connecting shaft 7 in a bearing connection manner, so that the fixed clutch 9 and the first sprocket 10 can rotate relative to each other on the first connecting shaft 7;

[0037] The second gear 6 is keyed to a second connecting shaft 11, the second connecting shaft 11 is keyed to a second sprocket 12, and the second sprocket 12 is connected to the first sprocket 10 through a first transmission chain 13;

[0038] The gantry 1 is also provided with a control component for driving the sliding clutch 8 to open and close with the fixed clutch 9 on the first connecting shaft 7. The control component includes a first mounting plate 15. A fixed box 14 is provided on the gantry 1. The first sprocket 10, the sliding clutch 8, the fixed clutch 9, the second sprocket 12 and the first transmission chain 13 are all arranged in the fixed box 14. The sliding clutch 8 is rotatably connected to the first mounting plate 15. The first mounting plate 15 is provided with a first clutch pull rod 16 which is symmetrically arranged on both sides. The ends of the first clutch pull rods 16 on both sides away from the first mounting plate 15 are provided with second clutch pull rods 17. The ends of the second clutch pull rods 17 on both sides away from the first clutch pull rod 16 are movably arranged to pass through the fixed box 14. The outer side of the fixed box 14 is provided with a horizontally arranged connecting rod 18, the two ends of the connecting rod 18 are respectively fixedly connected to the protruding ends of the second clutch rods 17 on both sides, and a cam 19 is rotatably connected to the connecting rod 18, and an adjusting handle 20 is arranged on the cam 19. The cam 19 is closely arranged to the outer wall of the fixed box 14. When the cam 19 rotates on the connecting rod 18, it can drive the connecting rod 18, the first clutch rod 16 and the first mounting plate 15 to perform corresponding forward and backward movements by squeezing the fixed box 14, so that the sliding clutch 8 and the fixed clutch 9 perform corresponding opening and closing actions. The second clutch rods 17 on both sides are respectively sleeved with pull rod springs 21, and the two ends of the pull rod springs 21 on both sides are respectively connected to the corresponding first clutch rod 16 and the inner wall of the fixed box 14, so as to facilitate subsequent resetting actions.

[0039] Through the above-mentioned arrangement, when the first gear 5 and the second gear 6 are separated under the action of the adjusting component 4, at this time, by using the adjusting handle 20 to rotate the cam 19, after the cam 19 rotates, by squeezing the outer wall of the fixed box 14, it can drive the first clutch rod 16 and the first mounting plate 15 to move toward the fixed box 14, so that the sliding clutch 8 can move toward the direction close to the fixed clutch 9, so that the sliding clutch 8 and the fixed clutch 9 can be closed. In this process, the pull rod springs 21 on both sides are compressed. After the sliding clutch 8 and the fixed clutch 9 are closed, the second gear 6 rotates to drive the second sprocket 12 to rotate. The rotation of the second sprocket 12 can drive the first sprocket 10 to rotate under the action of the transmission chain. The rotation of the first sprocket 10 causes the fixed clutch 9 to rotate. The rotation of the fixed clutch 9 can cause the sliding clutch 8 to rotate, which can drive the first connecting shaft 7 to rotate. The rotation of the first connecting shaft 7 can drive the first gear 5 to follow the rotation, so that the first gear 5 can still rotate synchronously with the second gear 6, so that when the second gear 6 is subsequently re-engaged with the first gear 5 under the action of the adjustment component 4, the second gear 6 and the first gear 5 will not have a tooth top to tooth top phenomenon, so as to avoid the occurrence of tooth collision phenomenon; and when the first gear 5 and the second gear 6 are re-engaged under the action of the adjustment component 4, at this time, the adjustment handle 20 is released, and the pull rod springs 21 on both sides perform a reset movement to drive the first clutch pull rod 16 and the first mounting plate 15 to move away from the fixed box 14 side, so that the sliding clutch 8 and the fixed clutch 9 are separated to avoid interference in the transmission relationship.

[0040] Since the second gear 6 needs to move up and down, the second sprocket 12 will also move up and down. At this time, the first transmission chain 13 is easy to fall off due to the change in the distance between the first sprocket 10 and the second sprocket 12. In order to ensure that the first transmission chain 13 is not easy to fall off, a chain tensioning assembly is also provided in the gantry 1. The chain tensioning assembly includes a tensioning seat 22, and the tensioning seat 22 is fixedly arranged on the inner wall of the fixed box 14. The tensioning seat 22 is provided with a sprocket seat 23 which is symmetrically arranged on the left and right. The sprocket seats 23 on both sides are connected to the tensioning seat 22 by setting a tensioning spring 24. The sprocket seats 23 on both sides are rotatably connected with a tensioning sprocket 25. The tensioning sprockets 25 on both sides are symmetrically arranged on both sides of the first transmission chain 13, and the tensioning sprockets 25 on both sides are meshed and connected with the first transmission chain 13. Through the above-mentioned arrangement, when the second gear 6 and the first gear 5 are in a separated state, the distance between the first sprocket 10 and the second sprocket 12 is the maximum. At this time, the first transmission chain 13 is in a normal working state, and the tensioning wheels on both sides are pushed away, so that the tensioning springs 24 on both sides are in a compressed state. When the second gear 6 and the first gear 5 are in an engaged state, the distance between the first sprocket 10 and the second sprocket 12 is the minimum. At this time, the first transmission chain 13 is in a relaxed state, and the tensioning wheels on both sides start to work, and the first transmission chain 13 is compressed under the action of the corresponding tensioning springs 24 to avoid the first transmission chain 13 from falling off.

[0041] In order to adapt to the processing of C-shaped steel and sigma-shaped steel, the gantry 1 is also rotatably connected with a third embossing shaft 26 and a fourth embossing shaft 27. The third embossing shaft 26 is arranged at the same horizontal position as the first embossing shaft 202, and the fourth embossing shaft 27 is arranged at the same horizontal position as the second embossing shaft 303. The third embossing shaft 26 is provided with a third embossing roller 28, and the fourth embossing shaft 27 is provided with a fourth embossing roller 29. The second embossing shaft 303 is also provided with a third sprocket 30, and the fourth embossing shaft 27 is also provided with a fourth sprocket 31. The third sprocket 30 and the fourth sprocket 31 are connected together by a second transmission chain 32. The third embossing roller 28 and the fourth embossing roller 29 are arranged to cooperate with the first embossing roller 201 and the second embossing roller 304 to perform the required steel processing and forming work.

[0042] The working principle of the utility model is that when processing, the second rib pressing shaft 303 is connected to an external driving motor to make it the active shaft. The rotation of the second rib pressing shaft 303 can drive the rotation of the first rib pressing shaft 202 and the fourth rib pressing shaft 27. The third rib pressing shaft 26 is a non-powered rotating shaft, which cooperates with the external feeding device. When feeding, the third rib pressing shaft 26 will rotate according to the feeding direction. Then, according to the processing requirements, the control adjustment component 4 and the control component can work accordingly.
