Description

Technical Field

[0001] This utility model relates to the field of diameter reduction machine technology, specifically to a device for fixing and adjusting the transmission star wheel of a diameter reduction machine. Background Technology

[0002] The necking machine is a non-cutting machining equipment with advantages such as high production efficiency, simple process, easy operation, raw material saving, and stable quality. It uses hydraulic technology to feed the portion of round steel, rebar, etc., that needs to be necked into a special mold for cold shrinking and pressing. The density of the steel in the necked portion can be greatly increased, thereby improving the material's compressive strength. The transmission star wheel of the necking machine is usually disc-shaped with multiple evenly distributed toothed grooves or slots on its edge, used to interact with the workpiece or material being transported to achieve precise positioning and transmission. The shape and size of these toothed grooves or slots are designed according to different necking machine applications and workpiece types to ensure the stability and reliability of transmission.

[0003] Existing reducing machines cannot adjust the transmission star wheel according to actual needs after installation. This means that when processing workpieces of different sizes, the reducing machine needs to be equipped with different specifications of transmission star wheels, which makes the reducing machine inconvenient to use. To address this, we propose a device for fixing and adjusting the transmission star wheel of a reducing machine. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fixing and adjusting device for a transmission star wheel of a reducing machine, comprising a base and a column, the column being located at the top of the base, a lead screw being rotatably connected between the top and bottom of the inner cavity of the column, a first bevel gear being fixedly connected to the lower side of the outer wall of the lead screw, a lifting block being screwed to the upper side of the outer wall of the lead screw, connecting rods being fixedly connected to the left and right side walls of the lifting block, a connecting plate being fixedly connected to the end of the connecting rod, a second motor being fixedly connected to the lower side of the left side wall of the column, the end of the power output shaft of the second motor penetrating the column and extending into the inner cavity of the column, and a second bevel gear being fixedly connected to the end of the power output shaft of the second motor, the second bevel gear meshing and rotating with the first bevel gear.

[0006] As a further description of the above technical solution:

[0007] The bottom of the inner cavity of the base is provided with a guide groove, and a guide block is slidably connected to the inner cavity of the guide groove.

[0008] As a further description of the above technical solution:

[0009] The top of the guide block is fixedly connected to a mounting box, and the inner cavity of the mounting box has rotating wheels connected to rotating shafts.

[0010] As a further description of the above technical solution:

[0011] The front and rear ends of the rotating shaft are fixedly connected to movable wheels, and the middle of the outer side wall of the rotating shaft is fixedly connected to a first gear.

[0012] As a further description of the above technical solution:

[0013] A first motor is fixedly connected to the upper side of the front wall of the inner cavity of the mounting box, and a second gear is fixedly connected to the end of the power output shaft of the first motor. The second gear meshes with the first gear and rotates.

[0014] As a further description of the above technical solution:

[0015] A vertical plate is fixedly connected to the top of the connecting plate, and a third motor is fixedly connected to the left side wall of the vertical plate.

[0016] As a further description of the above technical solution:

The power output shaft of the third motor is fixedly connected to a mounting plate, and a star wheel body is screwed between the inner side walls of the mounting plate.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. The fixing and adjusting device of the transmission star wheel of the reducing machine is achieved by a second motor driving a second bevel gear to rotate, which in turn drives a first bevel gear to rotate. The first bevel gear then drives a lead screw to rotate, which in turn drives a lifting block to move. This lifting block then drives a connecting rod to move, which in turn drives a connecting plate to move. This adjusts the height of the star wheel body, enabling the star wheel body to transmit workpieces of different diameters. Thus, the device can adjust the height of the transmission star wheel to facilitate the transmission of workpieces of different diameters.

[0020] 2. The fixing and adjusting device for the transmission star wheel of the reducing machine is achieved by a first motor driving a second gear to rotate, which in turn drives the first gear to rotate, thereby causing the rotating shaft to rotate. The rotating shaft then drives a moving wheel to move, which in turn moves the mounting box horizontally. This, in turn, moves the fixed column on top of the mounting box, thereby adjusting the lateral position of the star wheel body. Simultaneously, as the mounting box moves, a guide block slides in a guide groove to guide and limit the mounting box, preventing it from shifting during movement. This allows the device to adjust the lateral position of the transmission star wheel, facilitating the transmission of workpieces of different lengths. Attached Figure Description

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0029] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] This utility model provides a fixing and adjusting device for the transfer star wheel of a reducing machine. It can adjust the height of the transfer star wheel to facilitate the transfer of workpieces of different diameters, and can also adjust the lateral position of the transfer star wheel to facilitate the transfer of workpieces of different lengths. Please refer to [link to relevant documentation]. Figure 1-5 It includes a base 100 and a column 200;

[0031] Please see Figure 1-3The bottom of the inner cavity of the base 100 is provided with a guide groove 110. A guide block 120 is slidably connected to the inner cavity of the guide groove 110. A mounting box 130 is fixedly connected to the top of the guide block 120. A rotating shaft 140 is connected to the rotating wheels on the front and rear side walls of the inner cavity of the mounting box 130. Moving wheels 150 are fixedly connected to the front and rear ends of the rotating shaft 140. A first gear 160 is fixedly connected to the middle of the outer side wall of the rotating shaft 140. A first motor 170 is fixedly connected to the upper side of the front side wall of the inner cavity of the mounting box 130. A second gear 180 is fixedly connected to the end of the power output shaft of the first motor 170. The second gear 180 and the first gear 160 are connected to each other. The meshing rotation is achieved by the first motor 170 driving the second gear 180 to rotate, which in turn drives the first gear 160 to rotate, thereby causing the rotating shaft 140 to rotate. The rotating shaft 140 then drives the moving wheel 150 to move, which in turn drives the mounting box 130 to move horizontally. This causes the top fixed column 200 of the mounting box 130 to move, thereby adjusting the lateral position of the star wheel body 290. At the same time, when the mounting box 130 moves, the guide block 120 slides in the guide groove 110 to guide and limit the mounting box 130, preventing the mounting box 130 from deviating during the movement.

[0032] In summary, this allows the device to adjust the lateral position of the transmission star wheel, facilitating the transmission of workpieces of different lengths.

[0033] Please refer to it again. Figure 1-5The column 200 is located on top of the base 100. Specifically, the column 200 is fixedly connected to the top of the mounting box 130. A lead screw 210 is rotatably connected between the top and bottom of the inner cavity of the column 200. A first bevel gear 211 is fixedly connected to the lower side of the outer wall of the lead screw 210. A lifting block 220 is screwed to the upper side of the outer wall of the lead screw 210. A connecting rod 230 is fixedly connected to the left and right side walls of the lifting block 220. A connecting plate 240 is fixedly connected to the end of the connecting rod 230. A second motor 250 is fixedly connected to the lower side of the left side wall of the column 200. The end of the power output shaft of the second motor 250 passes through the column 200 and extends into the inner cavity of the column 200. A second bevel gear 251 is fixedly connected to the end of the power output shaft of the second motor 250. The second bevel gear 251 meshes with the first bevel gear 211 and rotates. The top of the connecting plate 240 is fixedly connected to... A vertical plate 260 is connected to the vertical plate 260. A third motor 270 is fixedly connected to the left side wall of the vertical plate 260. The end of the power output shaft of the third motor 270 passes through the vertical plate 260 and extends to the right side wall of the vertical plate 260. A mounting plate 280 is fixedly connected to the end of the power output shaft of the third motor 270. A star wheel body 290 is screwed between the inner side walls of the mounting plate 280. The second motor 250 drives the second bevel gear 251 to rotate, which in turn drives the first bevel gear 211 to rotate. The first bevel gear 211 then drives the lead screw 210 to rotate, which in turn drives the lifting block 220 to move. The lifting block 220 then drives the connecting rod 230 to move, which in turn drives the connecting plate 240 to move, thereby adjusting the height of the star wheel body 290. This allows the star wheel body 290 to transfer workpieces of different diameters.

[0034] In summary, this allows the device to adjust the height of the transmission star wheel, facilitating the transmission of workpieces of different diameters.

[0035] In practical use, those skilled in the art first install the device on the reducing machine using the base 100, then fix the star wheel body 290 using the mounting plate 280. Subsequently, the first motor 170 drives the second gear 180 to rotate, which in turn drives the first gear 160 to rotate, causing the rotating shaft 140 to rotate. This, in turn, drives the moving wheel 150 to move, causing the mounting box 130 to move horizontally, thereby adjusting the lateral position of the star wheel body 290. Then, the second motor 250 drives the second bevel gear 251 to rotate, causing the second bevel gear... Gear 251 drives the first bevel gear 211 to rotate, which in turn drives the lead screw 210 to rotate. This causes the lead screw 210 to move the lifting block 220, which in turn moves the connecting rod 230. The connecting rod 230 then moves the connecting plate 240, adjusting the height of the star wheel body 290. Once the star wheel body 290 is in the correct position, the third motor 270 drives it to rotate. During this rotation, the groove on the star wheel body 290 carries the workpiece onto the reducing machine, allowing the reducing machine to process the workpiece.
