Description

Technical Field

[0001] The invention relates to the technical field of seamless steel pipe hot rolling equipment, in particular to a mandrel cooling dialing and supporting device. Background Art

[0002] At present, in the production process of seamless steel pipes, after the rough pipe is rolled on the pipe rolling mill, it enters the rod stripping machine to remove the mandrel, and the mandrel enters the cooling pool for cooling after being removed from the rough pipe. An existing set of material-digging and supporting mechanisms is to fix multiple material-digging hooks and supporting hooks on two sets of material-digging shafts respectively. Each set of material-digging shafts is composed of three shafts, and the shafts are connected by sleeve bevel keys. The two sets of material-digging shafts are fixed on the pool mounting plate through multiple double-hole bearing seats at the same time. The double-hole bearing seat fixing bolts are connected from the bottom of the bearing seat to the upper cover as a whole. One cylinder drives a set of material-digging shafts to rotate, and the mandrel is pushed from the roller into the supporting hook. The other two cylinders drive another set of material-digging shafts to rotate and push the mandrel on the supporting hook into the cooling water pool for cooling. During daily use, the core rod with a larger outer diameter is pushed from the material-pushing hook to the supporting hook with a greater impact force, which often causes the supporting hook to wear, become loose, or break, and the connecting bolts of the double-hole bearing seat become loose and damaged. The entire set of material-pushing and supporting mechanism needs to be disassembled and replaced, which is inconvenient for maintenance. The site urgently needs a set of simple structure, easy maintenance, stable and reliable push-in and support hook device. Summary of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the above prior art and to provide a mandrel cooling dial-in and supporting device which has a simple structure, is easy to install and maintain, and can effectively save troubleshooting time.

[0004] To achieve the above object, the present invention provides the following technical solutions:

[0005] A mandrel cooling push-in and support device comprises a loading mechanism and a taking-out mechanism, wherein:

[0006] A feeding mechanism, the feeding mechanism comprises a feeding arm assembly, a feeding shaft, a single-hole bearing seat and a feeding drive assembly; the feeding shaft extends along a first direction and is mounted on a water pool mounting plate through a single-hole bearing seat, the feeding arm assembly comprises a plurality of feeding arms fixed to the feeding shaft at intervals along the first direction, and the feeding arm extends along a second direction, the feeding arm assembly has a first station and a second station, when the feeding arm assembly is in the first station, it is used to receive the core rod transferred by the material taking mechanism, and when the feeding arm assembly is in the second station, it is used to transport the received core rod into the water pool; the output end of the feeding drive assembly is connected to the feeding shaft, and when in action, it drives the feeding shaft to rotate, so as to drive the feeding arm assembly to switch between the first station and the second station;

[0007] The material picking mechanism includes a material picking arm assembly and a material picking drive assembly; the material picking arm assembly includes a plurality of material picking arms arranged at intervals along a first direction, one end of each material picking arm is sleeved on a feeding shaft, and each material picking arm is relatively fixed, and the other end of each material picking arm is away from the feeding arm, the material picking arm assembly has a first station and a second station, when the material picking arm assembly is in the first station, it is used to pick up the core rod, and when the material picking arm assembly is in the second station, it is used to transfer the core rod to the feeding arm assembly by rolling under its own gravity; the output end of the material picking drive assembly is connected to the material picking arm assembly to drive the material picking arm assembly to switch between the first station and the second station. Through this setting, the material picking hooks and the supporting hooks on the original two sets of material picking shafts are reduced to one set of feeding shafts, the overall structure is simple, the feeding shaft can be installed on the pool mounting plate through a single-hole bearing seat, the installation and maintenance are convenient, and the fault handling time can be effectively saved and the production efficiency can be improved.

[0008] Furthermore, the feeding drive assembly includes a feeding cylinder and a swing arm; the output end of the feeding cylinder is connected to the first end of the swing arm, and the second end of the swing arm is connected to the feeding shaft to realize the rotation of the feeding shaft. Through this arrangement, the feeding cylinder is used to push the swing arm to swing, thereby driving the feeding shaft to rotate, so that the feeding arm fixedly connected to the feeding shaft switches between the first station and the second station, and realizes receiving the core rod transferred by the material taking mechanism, and conveying the received core rod to the water pool.

[0009] Furthermore, the number of the feeding drive components is two groups, and the two groups of the feeding drive components are respectively located at the two ends of the feeding shaft. By setting two groups of feeding drive components, and respectively located at the two ends of the feeding shaft, the bearing capacity of the feeding shaft and the feeding arm can be guaranteed, and the deformation of the feeding shaft can be prevented, and each feeding arm can be ensured to be at the same height.

[0010] Furthermore, it also includes a first cylinder support, wherein two first cylinder supports are respectively located at two ends of the feeding shaft, and the feeding cylinder is correspondingly installed on the first cylinder support. Through this arrangement, the installation stability of the first cylinder can be improved.

[0011] Furthermore, the fetching arm assembly further comprises a connecting rod; the connecting rod extends along a first direction, and each of the fetching arms is connected to the connecting rod to achieve relative fixation between the fetching arms.

[0012] Furthermore, the material taking drive assembly includes a material taking cylinder; the output end of the material taking cylinder is connected to an end of at least one material taking arm away from the material loading shaft to drive the material taking arm assembly to switch between the first station and the second station.

[0013] Furthermore, it also includes a second cylinder support, which is located in the middle of the connecting rod, and the material-taking cylinder is installed on the second cylinder support and connected to the material-taking arm located in the middle of the connecting rod. Through this arrangement, the material-taking cylinder is connected to the material-taking arm in the middle, which reduces the number of material-taking cylinders used, reduces costs, and enables the material-taking arm assembly to maintain balance during the working process to prevent the core rod from slipping.

[0014] Furthermore, the connecting rod is a hollow steel pipe. This arrangement can reduce the weight of the connecting rod and reduce the load of the material taking cylinder.

[0015] Furthermore, the loading arm and the taking arm are alternately arranged along the axial direction of the loading shaft. Through this arrangement, the loading arm and the taking arm will not affect each other when working.

[0016] Furthermore, the feeding shaft is one or multiple feeding shafts connected by a coupling. With this arrangement, the feeding shaft is one or multiple feeding shafts connected by a coupling, and under the impact of a core rod with a larger outer diameter, there will be no misalignment, and the feeding arm will not be uneven, causing the core rod to tilt after entering the water pool.

[0017] The present invention has the following advantages over the prior art:

[0018] 1. The core rod cooling device of the present invention has a feeding mechanism and a picking mechanism. The feeding arm assembly in the feeding mechanism is installed on the feeding shaft, and the feeding arm assembly is driven by the feeding drive assembly to receive and transport the core rod; the picking arm assembly of the picking mechanism is sleeved on the feeding shaft, and the picking arm assembly is driven by the picking drive assembly to pick up and transfer the core rod to the feeding arm assembly.

Moreover, the feeding shaft in the present invention only needs a single-hole bearing seat to be installed on the water tank mounting plate. Compared with the double-hole bearing seat in the prior art, the single-hole bearing seat of the present application is easy to install and maintain, which can effectively save fault handling time and improve production efficiency.

[0019] 2. The feeding shaft in the present invention is one or multiple shafts connected by couplings. Compared with the prior art in which the shafts are connected by sleeve bevel keys, the coupling connection has high stability. When the core rod with a larger outer diameter falls off the feeding arm, the feeding shafts are relatively fixed by the coupling, which is not easy to be misaligned and the feeding arm is not easy to be uneven, causing the core rod to tilt after entering the water pool.

[0029] Example:

[0030] like Figures 1 to 4As shown, the present invention provides a core rod cooling dialing and supporting device, comprising a feeding mechanism 1 and a picking mechanism 2, wherein: the feeding mechanism comprises a feeding arm assembly, a feeding shaft 101, a single-hole bearing seat 102 and a feeding drive assembly; the feeding shaft 101 extends along a first direction X and is mounted on a pool mounting plate 3 through the single-hole bearing seat 102, the feeding arm assembly comprises a plurality of feeding arms 103 fixed to the feeding shaft 101 at intervals along the first direction, and the feeding arms 103 extend along a second direction The loading arm assembly has a first station and a second station. When the loading arm assembly is in the first station, it is used to receive the core rod transferred by the picking arm 201 of the picking mechanism 2. When the loading arm assembly is in the second station, it is used to transport the received core rod to the water pool 4. The output end of the loading drive assembly is connected to the loading shaft 101. When it is in motion, it drives the loading shaft 101 to rotate, thereby driving the loading arm 103 to rotate around the loading shaft, so as to realize the switching of the loading arm assembly between the first station and the second station.

[0031] The material picking mechanism 2 includes a material picking arm assembly and a material picking drive assembly; the material picking arm assembly includes a plurality of material picking arms 201 arranged at intervals along a first direction, one end of each material picking arm 201 is sleeved on the material loading shaft 101, and each material picking arm 201 is relatively fixed, and the other end of each material picking arm 201 is away from the material loading arm 103, the material picking arm assembly has a first station and a second station, when the material picking arm assembly is in the first station, it is used to pick up the mandrel on the roller 6, and when the material picking arm assembly is in the second station, it is used to transfer the mandrel to the material loading arm assembly by rolling under its own gravity; the output end of the material picking drive assembly is connected to the material picking arm assembly to drive the material picking arm assembly to switch between the first station and the second station. The material picking arm 201 is only sleeved on the material loading shaft 101, and the rotation of the material loading shaft 101 will not drive the material picking arm 201 to move, and the material picking arm 201 is driven to move by the material picking drive assembly, and each material picking arm 201 moves synchronously. The feeding arm 103 and the picking arm 201 are alternately arranged along the axial direction of the feeding shaft 101. With this arrangement, the feeding arm 103 and the picking arm 201 will not affect each other when working. In this embodiment, the feeding hooks and the supporting hooks on the original two sets of feeding shafts are reduced to one set of feeding shafts, and the overall structure is simple. The feeding shaft 101 can be installed on the pool installation plate through the single-hole bearing seat 102, which is convenient for installation and maintenance, can effectively save fault handling time, and improve production efficiency.

[0032] like Figure 3As shown, the feeding drive assembly includes a feeding cylinder 104 and a swing arm 105; the output end of the feeding cylinder 104 is connected to the first end of the swing arm 105, and the second end of the swing arm 105 is fixedly connected to the feeding shaft 101. The feeding cylinder 104 pushes the swing arm 105 to swing, thereby driving the feeding shaft 101 to rotate so that the feeding arm fixedly connected to the feeding shaft switches between the first station and the second station, so as to receive the mandrel transferred by the material taking arm 201, and transport the received mandrel into the water pool. Specifically, the feeding drive assembly also includes a first cylinder support 106, and the feeding cylinder 104 is fixedly installed on the first cylinder support 106 through a pin shaft 7. Through this arrangement, the installation stability of the first cylinder 104 can be improved.

[0033] Preferably, the number of the feeding drive components is two groups, and the two groups of the feeding drive components are respectively located at the two ends of the feeding shaft 101. That is, the first cylinder support 106 is respectively arranged at the corresponding positions at the two ends of the feeding shaft 101, and the feeding cylinder 104 is installed through the first cylinder support 106, and the output end of the feeding cylinder 104 is correspondingly connected to the feeding arms 103 at the two ends of the feeding shaft 101 through the swing arm 105. By setting two groups of feeding drive components, and respectively located at the two ends of the feeding shaft, the bearing capacity of the feeding shaft and the feeding arm can be guaranteed, and the feeding shaft 101 can be prevented from being deformed due to weight, and each feeding arm 103 can be ensured to be at the same height.

[0034] In this embodiment, the material picking arm assembly further includes a connecting rod 202; the connecting rod 202 extends along the first direction, and each of the material picking arms 201 is connected by the connecting rod 202 to achieve relative fixation between each of the material picking arms 201. Under the drive of the material picking cylinder, each of the material picking arms 201 moves synchronously. Preferably, the connecting rod 202 is a hollow steel pipe. This setting can reduce the weight of the connecting rod and reduce the load bearing capacity of the material picking cylinder.

[0035] like Figure 4 As shown, the material taking drive assembly includes a material taking cylinder 203; the output end of the material taking cylinder 203 is connected to an end of at least one material taking arm 201 away from the feeding shaft 101, so as to drive the material taking arm assembly to switch between the first station and the second station. Through this arrangement, the material taking cylinder 203 is used to drive the material taking arm 201 to work, which has a simple structure and low cost.

[0036] It also includes a second cylinder support 204, which is located in the middle of the connecting rod 202. The feeding cylinder 203 is installed on the second cylinder support 204 through the pin 7 and is connected to the feeding arm 201 located in the middle of the connecting rod 202. Through this arrangement, the feeding cylinder 203 is connected to the feeding arm 201 in the middle, which reduces the number of feeding cylinders 203 used and reduces costs. At the same time, it can keep the feeding arm assembly balanced during the working process and prevent the core rod from slipping. The feeding arm located in the middle of the connecting rod is provided with a fixing ring 205 at its bottom, which is connected to the output end of the feeding cylinder 203 through the fixing ring 205.

[0037] In this embodiment, the feeding shaft 101 is one or multiple shafts connected by the coupling 5. In the prior art, the feeding shafts are connected by a sleeve bevel key, and the connection stability is weak. When a core rod with a larger outer diameter falls from the material taking arm to the feeding arm, the feeding shafts connected by the sleeve bevel key are dislocated by impact, resulting in the uneven feeding arm causing the core rod to tilt after entering the water pool. In this embodiment, the feeding shaft 101 is one or three feeding shafts connected by the coupling 5. Under the impact of the core rod with a larger outer diameter, there will be no dislocation, and the uneven feeding arm will not cause the core rod to tilt after entering the water pool.

[0038] Specific work:

[0039] The picking cylinder in the picking mechanism moves, driving the picking arm to rotate around the loading shaft to remove the mandrel from the roller; the picking cylinder in the loading mechanism moves, driving the loading shaft to rotate, thereby rotating the loading arm connected to the loading shaft, so that the loading arm is located at the first station, ready to receive the mandrel transferred by the picking arm; the picking cylinder continues to move, so that the mandrel rolls to the loading arm by its own gravity; after receiving the mandrel, the loading cylinder of the loading mechanism continues to move, so that the loading arm rotates, so as to transport the mandrel received by the loading arm into the water pool. The present invention is characterized in that the material picking and discharging functions are realized simultaneously through a set of loading shafts, and the structure is simple and easy to maintain.

[0040] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
