Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment of annular forgings, in particular to a water tank for heat treatment of annular forgings. Background Art

[0002] Heat treatment is an indispensable part of the production of ring forgings. The heat treatment production line includes tracks and an operating vehicle that can move along the tracks. A robotic arm is set on one side of the operating vehicle. The robotic arm is shaped like the forearm of a forklift and has functions such as lifting and retracting. A water trough is arranged under the track and a heat treatment furnace is arranged on one side of the track. The operating vehicle uses the robotic arm to take out the rack loaded with ring forgings from the heat treatment furnace, then moves it to the top of the water trough, and uses the lifting function of the robotic arm to send the rack into the water trough for quenching.

[0003] During the above quenching process, the robot arm of the operating vehicle needs to be immersed in the water tank with the material rack all the time, so that the material rack can be taken out of the water tank conveniently after the quenching is completed. In this way, the quenching operation needs to occupy the operating vehicle, and only one furnace of workpieces can be quenched in the water tank, which affects the continuity of the heat treatment production line and is not conducive to improving production efficiency.

[0004] Therefore, a technical solution is currently needed to solve the technical problem that the traditional quenching operation of annular forgings in a water tank requires the use of an operating vehicle robotic arm and can only perform the quenching operation of one furnace of workpieces, thus affecting production efficiency. Utility Model Content

[0005] The invention purpose of the utility model is to provide a water tank for heat treatment of annular forgings in order to solve the technical problem that the quenching operation of annular forgings in a traditional water tank needs to occupy the robot arm of the operating vehicle and can only perform the quenching operation of one furnace of workpieces, which affects the production efficiency.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A water trough for heat treatment of annular forgings comprises a trough body, wherein at least two cooling zones are arranged in the trough body, an operating zone is arranged between two adjacent cooling zones, a support frame is arranged at the bottom of each cooling zone, a plurality of avoidance grooves are arranged side by side on the support frame, and the avoidance grooves are connected to the operating zone.

[0008] The utility model discloses a water trough for heat treatment of annular forgings. When in use, an operating vehicle on a track forks out a material rack loaded with annular forgings in a heat treatment furnace and moves it above the water trough. A mechanical arm descends above an operating area of ​​the water trough, and a portion of the mechanical arm close to the forklift falls into the operating area. The front end of the mechanical arm falls into the cooling area and descends through an avoidance groove, so that the material rack falls onto a support frame in the cooling area, and then is drawn out from the side of the avoidance groove, and the next material rack is placed into another cooling area by the operating vehicle. The present application arranges more than two cooling zones in the water trough, and each cooling zone supports the material rack by a support frame with an avoidance groove. An operating area is arranged between two adjacent cooling zones, which is convenient for the operating vehicle mechanical arm to perform operations such as rising, descending, and lateral movement. This realizes simultaneous quenching operations of two or more annular forgings in the same water trough, thereby improving the efficiency of heat treatment operations.

[0009] As a preferred solution of the utility model, the support frame includes a plurality of vertical plates arranged side by side, the vertical plates are connected to the bottom wall of the tank body, and the avoidance groove is formed between two adjacent vertical plates. By arranging a plurality of vertical plates side by side at the bottom of the cooling zone to form a support frame, the support of the annular forging material rack is achieved, and the avoidance groove formed between the vertical plates enables the operating vehicle to put the material rack into the support frame through the mechanical arm, and the mechanical arm can be pulled out from the avoidance groove, and the material rack on the support frame can also be lifted by inserting the operating vehicle mechanical arm into the avoidance groove.

[0010] As a preferred solution of the utility model, a limiting rod is provided on the side of the vertical plate close to the operating area. The limiting rod has a limiting effect on the material rack on the support frame to prevent the cooling water in the water tank from vibrating and causing the material rack to shift or detach from the support frame.

[0011] As a preferred solution of the utility model, a water changing area is provided on the side of the cooling area, and a partition net is provided in the water changing area, and the partition net and the inner wall of the tank body are enclosed to form the water changing area. The water changing area is formed in the water tank by the partition net and the inner wall of the tank body, so that the cooling water in the water tank can be replaced in the water changing area to keep the water temperature in the water tank within a suitable range. The partition net can isolate the debris falling off the annular forging to prevent the debris from entering the water pump, pipeline or cooling water tank.

[0012] As a preferred solution of the utility model, two water exchange areas are correspondingly arranged in each cooling zone, and the two water exchange areas are respectively arranged on both sides of the cooling zone. The two water exchange areas respectively replace the cooling water in the water tank from both sides of the cooling zone, thereby improving the cooling water circulation efficiency and the fluidity of the cooling water in the water tank, so that the quenching effect of the annular forging is more uniform and the quenching efficiency is higher.

[0013] As a preferred solution of the utility model, the inner wall of the tank body is connected with a plurality of wall guard plates, the wall guard plates are arranged one by one with the partition nets, and the ends of the partition nets are connected with the wall guard plates. The wall guard plates support the partition nets located on the inner wall of the tank body, which can improve the structural strength of the partition nets and prevent deformation during the cooling water oscillation process.

[0014] As a preferred solution of the utility model, it also includes a cooling water tank, the cooling water tank is connected with a water inlet pipe and a water outlet pipe, the water inlet pipe and the water outlet pipe are respectively connected with the water exchange area. A heat exchange plate is arranged in the cooling water tank, which can cool the hot water drawn from the water tank and then send it back to the water tank through the water outlet pipe, so that the water temperature in the water tank is kept within a suitable range, so as to achieve the purpose of recycling cooling water.

[0015] As a preferred solution of the utility model, the water inlet pipe and the water outlet pipe are respectively connected with water pumps, which improves the running efficiency of cooling water and provides a higher pressure for the water sent back to the water tank from the cooling water tank, so that the returned cooling water impacts the cooling water in the original water tank, thereby achieving the effect of stirring the cooling water in the water tank, thereby making the cooling water contact with the annular forging more uniformly, and improving the quenching efficiency and quenching quality.

[0016] As a preferred solution of the utility model, there are two cooling zones, which are respectively arranged near the inner walls at both ends of the tank body. When two cooling zones are arranged in the water tank, two furnaces of annular forgings can be quenched at the same time, and the two cooling zones share one operating area, which reduces the floor space of the water tank and improves the heat treatment production efficiency.

[0017] As a preferred solution of the utility model, there are three cooling zones, which are respectively arranged at both ends and the middle of the inner cavity of the tank body. By setting three cooling zones in the water tank, the cooling operation of three furnaces of annular forgings can be carried out simultaneously. When the length of the production line increases, the number of heat treatment furnaces increases accordingly. The increase of cooling zones in the water tank is to meet the demand of production capacity. The adjacent cooling zones are separated by the operating zone to ensure that the operating vehicle mechanical arm can exit after entering each cooling zone to avoid occupying the operating vehicle.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0019] The present application sets up more than two cooling zones in a water tank, and in each cooling zone, a material rack is supported by a support frame with an avoidance groove. An operating area is set between two adjacent cooling zones to facilitate the operation of the robot arm of the operating vehicle to perform operations such as rising, lowering, and lateral movement. This enables quenching operations of two or more ring forgings in the same water tank to be carried out simultaneously, thereby improving the efficiency of heat treatment operations.

[0033] When in use, the operating vehicle on the track forks out the material rack loaded with annular forgings in the heat treatment furnace and moves it above the water tank 1.

[0037] In this embodiment, three cooling zones 11 are set in the water tank 1 to meet the cooling operation of three furnaces of annular forgings at the same time. When the length of the production line increases, the number of heat treatment furnaces increases accordingly. The cooling zone 11 in the water tank 1 is increased to meet the production capacity requirements.
