Abstract
Description
Technical Field
[0001] This utility model belongs to the field of steel pipe processing technology, specifically a synchronous feeding device for steel pipe cutting. Background Technology
[0002] In the steel pipe processing industry, fixed-length cutting is a crucial process. Currently, the common feeding methods are continuous and intermittent. The continuous method involves setting up a moving chuck and clamping it at the end of the steel pipe. The movement of the moving chuck pushes the steel pipe forward. However, this method requires a track longer than the length of the steel pipe, resulting in a large overall footprint for the equipment, which is inconvenient for installation or relocation.
[0003] Intermittent chucks, on the other hand, use a moving chuck to transport the steel pipe to a certain position, and then the moving chuck returns to the starting position to clamp the steel pipe again and move it. During the process of the moving chuck returning, the cutting of the steel pipe needs to be stopped. Therefore, there is a lot of idle waiting time, the equipment utilization rate is low, and the overall production efficiency is affected. Utility Model Content
[0004] This invention provides a synchronous feeding device for steel pipe cutting to overcome the deficiencies in the prior art.
[0005] This utility model is achieved through the following technical solution: A synchronous feeding device for cutting steel pipes includes a frame with a slide rail arranged laterally. A left moving block and a right moving block are arranged on the slide rail. The left and right moving blocks are driven by a drive device to move synchronously and in opposite directions on the slide rail. A clamping and rotating device is fixedly arranged below each of the left and right moving blocks. A robotic arm is also arranged on the frame, located to the right of the right moving block. A laser cutter is arranged on the robotic arm. The steel pipe is inserted into the clamping and rotating device and clamped and rotated by the clamping and rotating device.
[0006] In use, the left moving block is initially positioned on the left side of the equipment, and the right moving block is positioned on the right side. The clamping and rotating device on the left moving block clamps the steel pipe, while the clamping and rotating device on the right moving block is released. Then, the left moving block moves to the right, and the right moving block moves to the left, causing the steel pipe to move to the right and reach the desired cutting position. The laser cutting machine then performs the cutting. Simultaneously, the clamping and rotating device on the left moving block is released, and the clamping and rotating device on the right moving block is clamped. The steel pipe is clamped by the clamping and rotating device on the right side. Then, the left moving block moves to the left, and the right moving block moves to the right, thus achieving a relay of movement between the right and left moving blocks, thereby reducing idle waiting time and improving utilization.
[0007] Preferably, the drive device includes two synchronous belt devices fixedly mounted on the frame. Each synchronous belt device includes a synchronous belt, which is driven by a motor mounted on the frame and synchronously transmits power in opposite directions. The left and right moving blocks are respectively mounted on their corresponding synchronous belts. The movement of the synchronous belts causes the corresponding left and right moving blocks to move synchronously in opposite directions.
[0008] Preferably, the synchronous belt device further includes a drive shaft and synchronous pulleys fixedly sleeved on the drive shaft. The synchronous belts pass around the corresponding synchronous pulleys. A driving gear and a driven gear meshing with the driving gear are coaxially fixedly mounted on the two inner drive shafts, respectively. Either outer drive shaft is coaxially fixedly connected to the shaft of the drive motor. The drive shafts rotate under the drive of the drive motor, thereby driving the synchronous pulleys to rotate. The rotation of the synchronous pulleys drives the corresponding driving gears to rotate, and the rotation of the driving gears drives the driven gears to rotate synchronously and in opposite directions, thus enabling the two synchronous belts to drive synchronously and in opposite directions.
[0009] Preferably, the slide rail has a dovetail groove along its length, and a dovetail block is slidably fitted within the dovetail groove. A strip-shaped groove extends upwards from the top and bottom surfaces of the dovetail groove. The top and bottom surfaces of the dovetail block are fixedly connected to the slider and the clamping rotation device respectively via connecting blocks passing through the strip-shaped grooves. The dovetail groove enables support for the clamping rotation device mounted on the slider while allowing the left and right moving blocks to move.
[0010] Preferably, the clamping and rotating device includes a mounting plate and a pneumatic chuck mounted on the mounting plate. The pneumatic chuck is driven to rotate by a rotary motor mounted on the mounting plate. The connecting block is fixedly connected to the top surface of the mounting plate, and the steel pipe passes through the pneumatic chuck.
[0011] The beneficial effects of this utility model are as follows: the use of this application can realize the synchronous movement of the steel pipe by the alternating movement of the left moving block and the right moving block, thereby realizing the continuous movement of the steel pipe, reducing waiting time and improving utilization.

[0016] A synchronous feeding device for steel pipe cutting, such as Figure 1 and Figure 2 As shown. It includes a frame 1, on which a slide rail is arranged laterally. A left moving block 2 and a right moving block 3 are arranged on the slide rail. The left moving block 2 and the right moving block 3 are driven by a driving device to move synchronously and in opposite directions on the slide rail. A clamping and rotating device 4 is fixedly arranged below each of the left moving block 2 and the right moving block 3. The clamping and rotating device 4 includes a mounting plate and a pneumatic chuck mounted on the mounting plate. The pneumatic chuck is driven to rotate by a rotary motor mounted on the mounting plate. A connecting block is fixedly connected to the top surface of the mounting plate. A steel pipe passes through the pneumatic chuck. The rotary motor driving the pneumatic chuck is existing technology and will not be described in detail.
[0017] The frame 1 is also equipped with a robotic arm, which is located on the right side of the right moving block 3. A laser cutting machine 10 is mounted on the robotic arm. The steel pipe is inserted into the clamping and rotating device 4 and is clamped and rotated by the clamping and rotating device 4. The robotic arm can adjust the cutting position of the laser cutting machine, and the clamping and rotating device 4 can ensure that the steel pipe rotates as needed during cutting to achieve better cutting.
[0018] In use, the left moving block 2 is initially located on the left side of the equipment, and the right moving block 3 is located on the right side. The clamping and rotating device 4 on the left moving block 2 clamps the steel pipe, while the clamping and rotating device 4 on the right moving block 3 is released. Then, the left moving block 2 moves to the right, and the right moving block 3 moves to the left, causing the steel pipe to move to the right and reach the desired cutting position. The laser cutting machine 10 then performs the cutting. At the same time, the clamping and rotating device 4 on the left moving block 2 is released, and the clamping and rotating device 4 on the right moving block 3 is clamped. The steel pipe is clamped by the clamping and rotating device 4 on the right side. Then, the left moving block 2 moves to the left, and the right moving block 3 moves to the right, thus achieving a relay of movement between the right moving block 3 and the left moving block 2, thereby reducing idle waiting time and improving utilization.
[0019] The drive device includes two synchronous belt devices 5 fixedly mounted on the frame 1. Each synchronous belt device 5 includes a synchronous belt, which is driven by a motor mounted on the frame 1 and synchronously transmitted in opposite directions. The left moving block 2 and the right moving block 3 are respectively mounted on the corresponding synchronous belts. The movement of the synchronous belts causes the corresponding left moving block 2 and right moving block 3 to move synchronously in opposite directions.
[0020] The synchronous belt device 5 further includes a drive shaft and synchronous pulleys fixedly sleeved on the drive shaft. The synchronous belts pass over the corresponding synchronous pulleys. On the inner two drive shafts, a driving gear 6 and a driven gear 7 meshing with the driving gear 6 are coaxially fixedly mounted, respectively. Either outer drive shaft is coaxially fixedly connected to the shaft of the drive motor. The drive shafts rotate under the drive motor's power, thereby driving the synchronous pulleys to rotate. The rotation of the synchronous pulleys drives the corresponding driving gear 6 to rotate, and the rotation of the driving gear 6 drives the driven gear 7 to rotate synchronously and in opposite directions, thus enabling the two synchronous belts to drive synchronously and in opposite directions.
[0021] The slide rail has a dovetail groove 8 along its length. A dovetail block 9 is slidably fitted inside the dovetail groove 8. A strip-shaped groove extends upwards from the top and bottom surfaces of the dovetail groove 8. The top and bottom surfaces of the dovetail block 9 are fixedly connected to the slider and the clamping rotating device 4 respectively via connecting blocks passing through the strip-shaped grooves. The dovetail groove 8 can support the clamping rotating device 4 mounted on the slider while allowing the left moving block 2 and the right moving block 3 to move.
