Description

Technical Field

[0001] This utility model relates to the field of metal forging technology, and in particular to a cooling device for forgings. Background Technology

[0002] In the metal forging process, forgings require rapid cooling after forming to stabilize their microstructure and mechanical properties. Traditional cooling methods often employ natural cooling or simple spray cooling, which suffers from low cooling efficiency and poor uniformity. Furthermore, moisture easily remains on the surface of the cooled forgings, necessitating an additional drying process, leading to extended production cycles and increased energy consumption. In addition, while some equipment uses airflow cooling, the duct design is rudimentary, with airflow only blowing on the forgings from a single direction. This can create cooling blind spots on the back or in recessed areas, resulting in uneven microstructure and properties, and affecting product yield. Utility Model Content

[0003] This utility model addresses the shortcomings of existing technologies by providing a cooling device for forgings, the specific technical solution of which is as follows:

[0004] A forging cooling device includes a cooling box and a placement mesh frame. The top of the placement mesh frame is provided with a movable part, which is used to drive the placement mesh frame to move along the vertical axis of the cooling box. Both sides of the placement mesh frame are provided with U-shaped drying frames. The two sets of U-shaped drying frames can move towards or away from the placement mesh frame. Several nozzles are evenly installed on the inner side of the U-shaped drying frame. A hot air fan is installed on the outer side of the U-shaped drying frame. The air outlet of the hot air fan is connected to the U-shaped drying frame through a pipe, and a solenoid valve is installed on the pipe.

[0005] Preferably, the movable part includes a mounting bracket installed on the cooling box, a hydraulic cylinder is mounted on the top of the mounting bracket, the output shaft of the hydraulic cylinder is connected to a U-shaped mounting bracket, and the bottom end of the U-shaped mounting bracket is fixedly connected to the placement mesh frame.

[0006] Preferably, it also includes an adjustment part for driving the two sets of U-shaped drying frames to move towards each other or away from each other. The adjustment part includes a mounting side frame for mounting the cooling box side, and a hydraulic cylinder two is mounted on the mounting side frame. The output rod of the hydraulic cylinder two is fixedly connected to the U-shaped drying frame.

[0007] Preferably, the top and bottom of the inner side of the U-shaped drying frame have multiple notches that are adapted to the U-shaped mounting bracket.

[0008] Preferably, the surface of the U-shaped drying frame has a plurality of ventilation holes.

[0009] The beneficial effects of this utility model are:

[0010] 1. By combining hot air blowers and nozzles, cooling and drying modes can be quickly switched, avoiding the drawbacks of separating cooling and drying in traditional processes, shortening the production cycle and improving production efficiency.

[0011] 2. After the U-shaped drying frame is closed, airflow can be sprayed onto the forging from multiple angles. Combined with the airflow circulation design of the ventilation holes, it ensures uniform cooling and drying of the forging, reducing deformation or performance differences caused by uneven temperature.

[0012] 3. Hydraulic cylinder one and hydraulic cylinder two control the up and down movement of the mesh frame and the opening and closing of the U-shaped drying frame, respectively. The control system can realize automated operation, reduce manual labor intensity, and improve production stability.

[0013] 4. The equipment integrates cooling and drying functions, reducing the floor space required; the hot air blower can adjust the airflow temperature according to process requirements, avoiding energy waste and meeting energy conservation and environmental protection requirements.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0019] Example

[0020] For forging cooling devices, please refer to [reference needed]. Figures 1-3The forging cooling device includes a cooling box 1 and a placement frame 8. The placement frame 8 is used to support the forging, and its top is equipped with a movable part that can drive the placement frame 8 to move along the vertical axis of the cooling box 1, realizing the vertical movement of the forging in and out of the cooling box 1. Both sides of the placement frame 8 are equipped with U-shaped drying frames 2. The two sets of U-shaped drying frames 2 can be controlled by an adjusting part to move towards or away from the placement frame 8, thereby surrounding or moving away from the forging, realizing the switching of cooling / drying positions.

[0021] Specifically, the moving part includes a mounting bracket 3 installed on top of the cooling box 1. A hydraulic cylinder 4 is fixedly mounted on the mounting bracket 3, and the output shaft of the hydraulic cylinder 4 is vertically connected to a U-shaped mounting bracket 5. The bottom end of the U-shaped mounting bracket 5 is fixedly connected to the placement frame 8. By extending and retracting the hydraulic cylinder 4, the placement frame 8 can be driven to move up and down within the cooling box 1, facilitating the loading and unloading of materials and the adjustment of the position of the forgings within the cooling box 1.

[0022] Specifically, the adjusting unit is used to drive the two sets of U-shaped drying frames 2 to move towards or away from each other, and includes mounting side frames 6 installed on both sides of the cooling box 1. A second hydraulic cylinder 61 is horizontally mounted on the mounting side frame 6, and the output rod of the second hydraulic cylinder 61 is fixedly connected to the U-shaped drying frame 2. When the second hydraulic cylinder 61 extends or retracts, it can push the U-shaped drying frame 2 to move in the horizontal direction, realizing the closing or separation of the two sets of U-shaped drying frames 2.

[0023] Specifically, the U-shaped drying frame 2 has a rectangular frame structure, with multiple notches 201 on the top and bottom of its inner side that are adapted to the U-shaped mounting bracket 5. When the two sets of U-shaped drying frames 2 move towards each other and close, the notches 201 can avoid the U-shaped mounting bracket 5, allowing the U-shaped drying frames 2 to fit tightly and completely surround the forging placed in the mesh frame 8, forming a closed cooling / drying space. Multiple nozzles 202 are evenly installed on the inner side of the U-shaped drying frame 2, and a hot air blower 7 is fixedly installed on the outer side. The air outlet of the hot air blower 7 is connected to the interior of the U-shaped drying frame 2 through a pipe. The hot air blower 7 can provide cooling airflow or hot airflow as needed, which is evenly sprayed onto the surface of the forging through the nozzles 202 to achieve cooling or drying functions. Several vent holes 200 are opened on the surface of the U-shaped drying frame 2 to discharge the moisture or hot air generated during the cooling or drying process, ensuring smooth airflow circulation.

[0024] Specifically, two sets of U-shaped drying frames 2 are located on the left and right sides of the mesh frame 8, respectively. The notches 201 correspond to the side plate positions of the U-shaped mounting bracket 5, ensuring that the U-shaped mounting bracket 5 can be embedded in the notches 201 when closed, without affecting the fit of the U-shaped drying frames 2. The nozzles 202 are evenly distributed inside the U-shaped drying frames 2 and are connected to the air outlet of the hot air blower 7 through pipes. Specifically, a solenoid valve can be installed on its pipes to facilitate switching between cooling airflow and hot airflow. The pipes use two sets of branch pipes, one for cooling (normal temperature) airflow and one for hot fluid airflow.

[0025] Workflow:

[0026] 1. Loading: Activate hydraulic cylinder 4 to retract its output shaft, causing the U-shaped mounting bracket 5 and the placement mesh frame 8 to rise to the top opening of the cooling box 1. The worker places the forgings into the placement mesh frame 8, ensuring even distribution.

[0027] 2. Cooling Process: The output shaft of hydraulic cylinder 4 extends, pushing the placement frame 8 down to the designated position inside the cooling box 1. Subsequently, the output shaft of hydraulic cylinder 61 extends, pushing the two sets of U-shaped drying frames 2 to move towards each other, passing through the notch 201 to avoid the U-shaped mounting bracket 5 and then fitting tightly together, completely surrounding the forging. The hot air blower 7 is started, and its output cooling airflow is like introducing room temperature air or cold air. The airflow enters the interior of the U-shaped drying frame 2 through the pipe and is evenly sprayed onto the surface of the forging through the nozzle 202, rapidly cooling the forging. The moisture and heat generated during the cooling process are discharged through the vent 200, ensuring cooling efficiency and uniformity.

[0028] 3. During the drying process: After cooling is complete, the hot air blower 7 switches to hot air mode and outputs high-temperature airflow to dry the surface of the forging through nozzle 202. During the drying process, the airflow circulation path is the same as that of the cooling process, and moisture is discharged through the vent 200 until the surface of the forging is dry.

[0029] 4. Unloading: After cooling or drying, the output shaft of hydraulic cylinder 2 61 retracts, causing the U-shaped drying frame 2 to move away from each other and separate. Subsequently, the output shaft of hydraulic cylinder 1 4 retracts, lifting the mesh frame 8 to the top of the cooling box 1, where the worker removes the forging, completing one processing cycle.

[0030] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
