Description

[Technical field]

[0001] The utility model relates to a steel pipe bending clamp. [Background technology]

[0002] After the steel elbow is cast, it is generally necessary to cut both ends to meet the actual size. Traditionally, laser cutting is used to cut both ends. The specific method is to fix one end of the steel elbow on a chuck, and the laser cutting head performs laser cutting on the other end of the steel elbow. After cutting, the cut end is fixed on the chuck to cut the other end. The operation is cumbersome and the processing efficiency is low. [Contents of the utility model]

[0003] The technical problem to be solved by the utility model is to provide a steel pipe bending clamp with high cutting efficiency.

[0004] The purpose of the utility model is achieved in this way:

[0005] A steel pipe bending fixture comprises a support, a tooling fixture arranged on one side of the support, and a first rotation drive device arranged on the other side of the support and used to drive the tooling fixture to rotate relative to the support. The tooling fixture comprises a rotating seat, two clamping seats arranged on the rotating seat, a clamping drive device for driving the two clamping seats to clamp and release each other, an upper chuck and a lower chuck respectively arranged on the two clamping seats, and a second rotation drive device arranged on one of the clamping seats and used to drive the upper chuck and the lower chuck to rotate.

[0006] The utility model adopts the above structure to fix the steel bent pipe to be cut between the upper chuck and the lower chuck. At this time, the laser cutting head can cut one end of the steel bent pipe. During the cutting process, the first rotary drive device drives the tooling fixture to rotate 360° relative to the support as a whole, so that the steel bent pipe rotates 360° relative to the laser cutting head, thereby completing the cutting of one end of the steel bent pipe. After cutting, the second rotary drive device drives the upper chuck and the lower chuck to rotate 90°, thereby rotating the other end of the steel bent pipe to the laser cutting head for cutting. It realizes the cutting of two pipe ends with one tooling, which greatly improves the efficiency of the cutting process.

[0007] As described above, a steel pipe bending clamp is provided with a rotating shaft for the corresponding upper clamp or lower clamp to rotate on the two clamping seats, and the output end of the second rotation drive device is connected to one of the rotating shafts. The second rotation drive device can drive the steel bent pipe clamped between the upper clamp and the lower clamp to rotate relative to the laser cutting head by driving one of the rotating shafts to rotate, thereby switching the pipe end to be cut.

[0008] In the steel pipe bending clamp as described above, the upper clamp and the lower clamp are provided with cavities matching the shape of the steel pipe bending, thereby preventing the steel pipe bending from being clamped.

[0009] As described above, a steel pipe bending clamp is provided with two slide rails on the rotating seat for the two clamping seats to slide respectively, and the clamping drive device has two to drive the two clamping seats to slide on the corresponding slide rails respectively. The clamping drive device drives the two clamping seats to slide on the corresponding slide rails when clamping and releasing each other, thereby ensuring the smoothness and accuracy of the movement.

[0010] As described above, a steel pipe bending clamp has a hollow shaft on the output end of the first rotating drive device, which passes through the support and is connected to the rotating seat. A current collector is provided at the other end of the hollow rotating shaft. The current collector leads out electric wires and is electrically connected to the clamping drive device and the second rotating drive device through the inside of the hollow rotating shaft, thereby supplying power to the clamping drive device and the second rotating drive device, and preventing the problem of wire winding when rotating the seat.

[0011] In the steel pipe bending fixture as described above, a large bearing is provided between the hollow rotating shaft and the support, and a first belt transmission mechanism is provided between the output end of the first rotary drive device and the hollow rotating shaft.

[0012] In the steel pipe bending clamp as described above, a small bearing is provided between the rotating shaft and the corresponding upper chuck or lower chuck, and a second belt transmission mechanism is provided between the output end of the second rotary drive device and the corresponding rotating shaft.

[0019] A steel pipe bending fixture comprises a support 1, a jig 2 arranged on one side of the support 1 and a first rotation drive device 3 arranged on the other side of the support 1 and used to drive the jig 2 to rotate relative to the support 1. The jig 2 comprises a rotating seat 21, two clamping seats 22 arranged on the rotating seat 21, a clamping drive device 23 for driving the two clamping seats 22 to clamp and release each other, an upper chuck 24 and a lower chuck 25 respectively provided on the two clamping seats 22, and a second rotation drive device 26 arranged on one of the clamping seats 22 and used to drive the upper chuck 24 and the lower chuck 25 to rotate.

[0020] The clamping seat 22 is provided with a rotating shaft 27 for the corresponding upper clamp 24 or lower clamp 25 to rotate, and the output end of the second rotary drive device 26 is connected to one of the rotating shafts 27. Preferably, a small bearing 8 is provided between the rotating shaft 27 and the corresponding upper clamp 24 or lower clamp 25, and the second rotary drive device 26 (preferably a motor) is fixedly connected to the clamping seat 22 provided with the upper clamp 24, and a second belt transmission mechanism 9 is provided between its output end and the rotating shaft 27 corresponding to the upper clamp 24. The second rotary drive device 26 can drive the steel bent pipe clamped between the upper clamp 24 and the lower clamp 25 to rotate relative to the laser cutting head by driving the rotating shaft 27 corresponding to the upper clamp 24 to rotate, thereby switching the pipe end to be cut.

[0021] In order to prevent the steel elbow from being clamped, the upper clamp 24 and the lower clamp 25 are provided with a cavity 20 matching the shape of the steel elbow.

[0022] In order to ensure the stability and accuracy of the movement, the rotating seat 21 is provided with two slide rails 28 for the two clamping seats 22 to slide, and the clamping driving device 23 has two to drive the two clamping seats 22 to slide on the corresponding slide rails 28. The clamping driving device 23 is preferably a cylinder, and its output end is connected to the two clamping seats 22 respectively. When the clamping driving device 23 is working, it can drive the two clamping seats 22 to slide on the corresponding slide rails 28 to achieve mutual clamping and loosening.

[0023] In order to solve the technical problem of rotating winding, a hollow shaft 4 is provided on the output end of the first rotating drive device 3, which passes through the support 1 and is connected to the rotating seat 21. A current collector 5 is provided at the other end of the hollow shaft 4. The current collector 5 leads out electric wires and is electrically connected to the clamping drive device 23 and the second rotating drive device 26 through the inside of the hollow shaft 4, thereby supplying power to the two clamping drive devices 23 and the second rotating drive device 26. Preferably, a large bearing 6 is provided between the hollow shaft 4 and the support 1, and a first belt transmission mechanism 7 is provided between the output end of the first rotating drive device 3 and the hollow shaft 4.

[0024] When the utility model is used, the clamping drive device 23 drives the two clamping seats 22 to loosen (such as Figure 3As shown), the steel elbow to be cut is placed on the lower clamp 25, and then the clamping drive device 23 drives the two clamping seats 22 to clamp (as shown Figure 4 As shown in the figure, the steel bend is clamped in the cavity 20 between the upper clamp 24 and the lower clamp 25. At this time, one end of the steel bend faces the laser cutting head, and the laser cutting head can cut the end of the steel bend. During the cutting process, the first rotary drive device 3 drives the tooling fixture 2 to rotate 360° along the X-axis direction relative to the support 1, so that the steel bend is rotated 360° relative to the laser cutting head, thereby completing the cutting of the end of the steel bend. During the cutting process, the laser cutting head does not need to move or rotate. After cutting, the second rotary drive device 26 drives the upper clamp 24 and the lower clamp 25 to rotate along the Y-axis direction. The first rotating drive device 3 drives the tooling fixture 2 to rotate 360° relative to the support 1 along the X-axis direction, so that the steel bend is rotated 360° relative to the laser cutting head, thereby completing the cutting of the other end of the steel bend. During the cutting process, the laser cutting head does not need to move or rotate. After cutting, the clamping drive device 23 drives the two clamping seats 22 to loosen, and the steel bend with both ends cut can be taken out. The utility model realizes the cutting of the two ends of the steel bend in one tooling, which greatly improves the efficiency of the cutting process.
