Cooling bed steel feeding device for rolled piece transportation

Abstract

The utility model discloses a cooling bed steel feeding device for rolled piece transportation, and belongs to the field of rolled piece transportation. The cooling bed steel feeding device for rolled piece transportation comprises a support, a chain is transversely arranged on the face, facing a cooling bed, of the support, and a pair of protruding blocks is arranged on the outer wall of the chain. The steel feeding device solves the problems that when an existing steel feeding device for the large bar cooling bed supports large bars and conveys the large bars to the cooling bed for cooling, only cut strip-shaped large bars can be supported and conveyed, large bars needing to be cut cannot be cut in the conveying process, and the large bars cannot be cut when materials which are not cut are conveyed. In order to solve the problem that the efficiency of conveying a rolled piece to a cooling bed is reduced due to the fact that the rolled piece is supported by a transversely-moving protruding block, when the rolled piece continuously faces the cooling bed, a pair of cutters relatively move to cut the rolled piece, and therefore the rolled piece can be continuously conveyed to the cooling bed, and the efficiency of conveying the rolled piece to the cooling bed is greatly improved. And the rolled pieces which are not cut can be continuously conveyed to the upper end of the cooling bed.

Description

Technical Field

[0001] This utility model relates to the field of rolled product transportation, specifically to a cooling bed steel-making device for transporting rolled products. Background Technology

[0002] The pre-cooling bed cooling device used for transporting rolled products is a crucial piece of equipment in steel rolling production. It automatically and efficiently transports hot-rolled steel to the cooling bed for cooling treatment, ensuring that the steel enters the pre-cooling table accurately and smoothly, while reducing surface defects such as scratches and dents, and improving steel quality and production efficiency.

[0003] Chinese Patent Publication No. CN216827940U discloses a steel-making device for a bar cooling bed, including a cooling bed input roller conveyor, a cooling bed fixed rack, a bar, a support frame, and a parallelogram double crank mechanism. By setting the parallelogram double crank mechanism, the support frame can be driven to rotate along a set trajectory, thereby transferring the bar from the cooling bed input roller conveyor to the cooling bed fixed rack. This avoids collisions between the bar and the cooling bed fixed rack, ensuring the surface quality of the bar, and does not affect the bar transportation process on the cooling bed input roller conveyor, resulting in higher bar transportation efficiency.

[0004] The steel cooling bed device of the aforementioned patent can only lift and transport the cut strip-shaped bars when it lifts and transports them to the cooling bed. It cannot cut the bars that need to be cut during the transport process. This results in the need to feed the uncut materials into the cutting device before loading, which reduces the efficiency of transporting the rolled pieces to the cooling bed. Utility Model Content

[0005] The purpose of this invention is to provide a cooling bed steelmaking device for transporting rolled products. A laterally moving protruding block supports the transported rolled product. As the rolled product continues to face the cooling bed, a pair of cutting tools move relative to each other to cut the rolled product, so that the uncut rolled product can be continuously transported to the upper part of the cooling bed, thus solving the problems mentioned in the background art.

A threaded bidirectional threaded rod is threaded through the upper end of the two cutting tools, and the rotation of the bidirectional threaded rod can generate relative movement with the through-position of the cutting tools. After restriction, the pair of cutting tools can move relative to each other and cut the rolled product. During the cutting process, the cutting tool can continuously move laterally with the rolled product.

[0007] Preferably, the upper end of the bidirectional threaded rod is provided with a connecting block, the bracket is embedded in the inside of the connecting block and is in sliding connection with the inside of the connecting block, and after being pushed, the connecting block can slide transversely at the upper end outside the bracket, and the transverse movement can be carried out along with the transverse movement of the rolled piece, so that a pair of cutters move along with the rolled piece and cut the rolled piece.

[0008] Preferably, the other side of the connecting block is provided with a first hydraulic rod, and the two ends of the first hydraulic rod are fixedly connected with the bracket and the connecting block through bolts, and a pair of second hydraulic rods are transversely arranged between the upper end outside the bidirectional threaded rod and the inside of the connecting block, and the pushing of the second hydraulic rods can make the pair of cutters move longitudinally downward and cut the rolled piece.

[0009] Preferably, one end of the bidirectional threaded rod is provided with a motor, and the thermal sensor is electrically connected with the corresponding motor of the second hydraulic rod and the bidirectional threaded rod, and after the rolled piece is continuously transmitted and detected by the thermal sensor, the thermal sensor can electrically start the corresponding motor of the second hydraulic rod and the bidirectional threaded rod, and after the thermal sensor is started, the rolled piece is cut.

[0010] Preferably, a plurality of limiting rollers are uniformly distributed transversely between the lower end of the thermal sensor and the chain, the lower end between two adjacent limiting rollers is filled with a filler strip, the limiting rollers are rotatably connected with the bracket, and when the rolled piece is transmitted to the periphery of the thermal sensor, the rolled piece is located between the limiting rollers and the chain, so that the rolled piece can be limited to avoid being lifted after being cut.

[0019] The present invention will be further described below with reference to specific embodiments.

[0020] Example 1

[0021] like Figure 1 As shown, the steel-rolling device for transporting rolled pieces on a cooling bed in this embodiment includes a support 5. Seven chains 3 are evenly distributed laterally on the side of the support 5 facing the cooling bed. A transmission disc 2 is provided on both sides of each of the seven chains 3, and the transmission disc 2 is meshed with the chain 3. The chain 3 is transmitted and supported by a pair of transmission discs 2. The transmission discs 2, through the output of a motor, can drive the chain 3 to transmit. A pair of protruding blocks 4 are provided on the outer wall of the chain 3. During transmission, the chain 3 drives the protruding blocks 4 to move along the chain 3. The protruding blocks 4 cause the contacted rolled piece to move laterally, moving the rolled piece towards the cooling bed.

[0022] In order to cut strip-shaped rolled pieces that need to be cut, such as Figure 1 and Figure 4 As shown, a pair of cutters 8 are provided at the front end of the support 5 facing the cooling bed. The cutters 8 move laterally with the strip-shaped workpiece and facilitate cutting the workpiece. A bidirectional threaded rod 13 is provided through the upper end of the two cutters 8, and the outside of the bidirectional threaded rod 13 is threaded with the through position of the cutter 8. A motor is provided at one end of the bidirectional threaded rod 13. The output of the motor drives the bidirectional threaded rod 13 to rotate, which can make the cutter 8 move relative to each other and cut off the workpiece.

[0023] Wherein, the upper end of the bidirectional threaded rod 13 is provided with a connecting block 15, the bracket 5 is embedded in the inside of the connecting block 15 and is in sliding connection with the inside of the connecting block 15, the connecting block 15 is transversely sliding at the upper end outside the bracket 5, so that the connecting block 15 and the pair of cutters 8 at the lower end move transversely along with the rolled piece being pushed, facilitating the subsequent cutting;

[0024] In addition, in order to push the connecting block 15 and the cutter 8, it is convenient to move the rolled piece being pushed and moved transversely, as shown in Figure 1 and Figure 4 The other side of the connecting block 15 is provided with a first hydraulic rod 6, and the two ends of the first hydraulic rod 6 are respectively fixedly connected with the bracket 5 and the connecting block 15 through bolts, the first hydraulic rod 6 pushes the connecting block 15 to move transversely under the support of the bracket 5, a pair of second hydraulic rods 7 are transversely arranged between the upper end outside the bidirectional threaded rod 13 and the inside of the connecting block 15, the pair of cutters 8 can move longitudinally towards the rolled piece being pushed through the pushing of the second hydraulic rod 7, and the first hydraulic rod 6, the second hydraulic rod 7 and the bidirectional threaded rod 13 correspond to the start of the motor to make the cutter 8 cut the rolled piece:

[0025] In order to avoid that the rolled piece is too long or too short to be cut when the rolled piece continuously moves towards the upcoiler, the rear end of the bracket 5 towards the cold bed is provided with a thermal sensor 12, and the thermal sensor 12 is electrically connected with the second hydraulic rod 7 and the motor corresponding to the bidirectional threaded rod 13, when the rolled piece continuously moves towards the upcoiler, the thermal sensor 12 detects the high-temperature rolled piece, then the second hydraulic rod 7 and the motor corresponding to the bidirectional threaded rod 13 are started, and when the rolled piece reaches the maximum length, the cutting is carried out, so that the rolled piece is transmitted to the cold bed with the same length;

[0026] In order to avoid that the rolled piece is lifted when being cut by the pair of cutters 8, as shown in Figure 1 and Figure 2 The lower end between the adjacent two limiting rollers 9 is filled with a filler strip 10 towards the chain 3, when the rolled piece continuously transmits and approaches the thermal sensor 12, the rolled piece will be located between the limiting roller 9 and the chain 3, the limiting roller 9 and the filler strip 10 can improve the stability of the rolled piece during cutting;

[0027] Wherein, the limiting roller 9 is rotatably connected with the bracket 5, and the friction during the transverse movement of the rolled piece contacting the limiting roller 9 can be offset by the rotation of the limiting roller 9;

[0028] In order to facilitate the protruding block 4 to stably push the rolled piece transversely, as shown in Figure 3 The upper end outside the protruding block 4 is provided with a groove 11, the rolled piece falls in the groove 11 to move transversely, and the recessed groove 11 can avoid the rolled piece from falling outside the protruding block 4;

[0029] A transmission rod 1 is provided at the center position between two adjacent transmission discs 2, and the transmission rod 1 is welded and fixed to the center position of the transmission disc 2. The two transmission rods 1 pass through the bracket 5 and are rotatably connected to the inside of the bracket 5. The bracket 5 can support the transmission rod 1 and the external chain 3. One end of one of the transmission rods 1 is provided with a motor. The output of the motor can drive the transmission disc 2 to rotate. The rotation of the transmission disc 2 can enable the chain 3 and the upper rolled piece to be transmitted.

[0030] To prevent the rolled piece from falling between two adjacent transmission discs 2 when it is being transferred to the upper end of the protruding block 4, such as... Figure 1 As shown, an anti-drop block 14 is arranged laterally between the thermal sensor 12 and a pair of cutting tools 8, and the anti-drop block 14 is located between two adjacent transmission discs 2.

[0031] Working principle: When using the device and conveying the rolled workpiece, the motor corresponding to one of the transmission rods 1 is started. The rotation of transmission rod 1 drives multiple chains 3 to transmit synchronously through the transmission disc 2. The transmission of chains 3 causes the connected protruding blocks 4 to move. When conveying the strip-shaped rolled workpiece to be cut, the workpiece is pushed by the protruding blocks 4 and continuously moves towards the cooling bed. During the movement, the extension and retraction of the first hydraulic rod 6 keeps the workpiece continuously positioned between a pair of cutters 8. When the thermal sensor 12 detects a high-temperature workpiece, the motors corresponding to the second hydraulic rod 7 and the bidirectional threaded rod 13 are started. The hydraulic rod 7 longitudinally pushes a pair of cutters 8 to move to both sides of the workpiece, while the rotation of the bidirectional threaded rod 13 causes the pair of cutters 8 to move relative to each other, completing the cutting of the workpiece. After cutting, the workpiece moves to the cooling bed after being pushed by the protruding block 4. The subsequent continuously conveyed workpieces wait for the next protruding block 4 to push. While waiting for the protruding block 4 to push, the cutter 8 resets and waits for the next cutting. When conveying strip-shaped workpieces that do not need to be cut, when the workpiece is conveyed to the upper end of the chain 3, it is supported and restricted by the anti-drop block 14, so that the workpiece moves towards the cooling bed one by one after being pushed by the protruding block 4.
