Description

Technical Field

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

[0002] After the forging of metal workpieces is completed, the forgings are cooled by spraying coolant in order to control the temperature, reduce thermal stress, improve product quality and performance, increase production efficiency and reduce costs. It also causes changes in the microstructure and macromorphology of the metal, optimizes the metal structure, and transforms the austenite phase at high temperature into the martensite phase at low temperature, thereby significantly improving the hardness and strength of the metal.

[0003] When metal workpieces are cooled after forging, the traditional liquid cooling method is to place the workpiece directly in the cooling pool. This cooling method may cause uneven temperature distribution inside the metal part, especially in large or complex-shaped forgings. This temperature non-uniformity may lead to non-uniform phase transformation, affecting the performance and quality of the forging. Utility Model Content

[0004] This disclosure relates to a forging cooling optimization device to address the problem that traditional liquid cooling methods, which involve placing the workpiece directly in a cooling pool, can lead to uneven temperature distribution within the metal part, especially in large or complex-shaped forgings. This uneven temperature distribution can result in non-uniform phase transformations, affecting the performance and quality of the forgings.

[0005] In a first aspect, this disclosure provides a forging cooling optimization device, specifically comprising: a cooling platform, a coolant return frame fixedly connected to the front of the cooling platform, a forging rotation drive component fixedly connected to the right surface of the cooling platform by bolts, a rotation support fixedly connected to the upper surface of the cooling platform, two rotation rollers rotatably connected inside the rotation support component via bearings, the right end of the front rotation roller being connected to the forging rotation drive component via a coupling, a coolant conveying frame fixedly connected above the rotation support component via a bracket, a coolant return pump mounted on the left surface of the coolant return frame by screws, the input end of the coolant return pump being connected to the bottom of the coolant return frame via a pipe, and the output end of the coolant return pump being connected to the coolant conveying frame via a pipe.

[0006] In at least some embodiments, a feeding interface is provided at the rear edge of the cooling platform, and a feeding channel is fixedly connected to the feeding interface.

[0007] In at least some embodiments, a return baffle is fixedly connected to the inside right side of the coolant return frame, and a diversion baffle is fixedly connected to the inside front of the coolant return frame.

[0008] In at least some embodiments, the front space inside the coolant return frame is divided into a coolant collection chamber on the left and a residue collection chamber on the right by a flow divider, and the coolant collection chamber is connected to the inlet pipe of the coolant return pump.

[0009] In at least some embodiments, a residue filter plate is connected between the inner left wall of the coolant return frame and the upper end of the diversion baffle, and the residue filter plate is inclined.

[0010] In at least some embodiments, the left and right ends of the rotary support roller are provided with support roller limiting flanges.

[0011] In at least some embodiments, the coolant delivery frame is an inverted "U"-shaped pipe, and a coolant nozzle is fixedly connected to the inner surface of the coolant delivery frame.

[0012] This utility model provides a forging cooling optimization device, which has the following beneficial effects:

[0013] The forging cooling device of this invention uses spray cooling to cool the forging. Spray cooling can cool the metal surface more evenly, reduce the occurrence of non-uniform phase transformation, and thus obtain a more uniform and stable metal structure. At the same time, a rotation drive structure for the forging is provided. The spray device surrounds the rotating forging and sprays it around the circumference, so that the forging is sprayed and cooled from different directions, which improves the uniformity of cooling and optimizes the forging cooling process.

[0014] Furthermore, during the cooling process of the forging, the coolant flows over the forging and enters the cooling platform above it, then flows into the coolant return rack. Due to the inclination of the coolant return rack, it converges into the coolant collection chamber. During the convergence process, it passes through the residue filter plate, which intercepts impurities in the coolant and filters it. This prevents impurities in the coolant from entering the coolant return pump and causing blockage, which could lead to malfunctions in the forging cooling device. The residue generated during forging is collected in the residue collection chamber, facilitating residue collection and equipment cleaning. Attached Figure Description

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1: Please refer to Figures 1 to 6 :

[0028] This utility model proposes a forging cooling optimization device, comprising: a cooling platform 1, a coolant return frame 2 fixedly connected to the front of the cooling platform 1, a forging rotation drive 3 fixedly connected to the right surface of the cooling platform 1 by bolts, a rotation support 4 fixedly connected to the upper surface of the cooling platform 1, two rotation support rollers 401 rotatably connected inside the rotation support 4 by bearings, the right end of the rotation support roller 401 located at the front being connected to the forging rotation drive 3 by a coupling, a coolant conveying frame 6 fixedly connected above the rotation support 4 by a bracket, a coolant return pump 7 installed on the left surface of the coolant return frame 2 by screws, the input end of the coolant return pump 7 being connected to the bottom of the coolant return frame 2 by a pipe, and the output end of the coolant return pump 7 being connected to the coolant conveying frame 6 by a pipe.

[0029] In this embodiment, a feeding interface 101 is provided on the rear edge of the cooling platform 1, and a feeding channel 5 is fixedly connected to the feeding interface 101. The feeding channel 5 facilitates the feeding of high-temperature forgings into the upper part of the rotary support platform 4, serving as a guide and temporary support.

[0030] In this embodiment, a return baffle 201 is fixedly connected to the right side of the interior of the coolant return frame 2, and a diversion baffle 202 is fixedly connected to the front of the interior of the coolant return frame 2. The front space inside the coolant return frame 2 is divided into a coolant collection chamber 203 on the left and a residue collection chamber 204 on the right by the diversion baffle 202. The coolant collection chamber 203 is connected to the inlet pipe of the coolant return pump 7. A residue filter plate 205 is connected between the left wall inside the coolant return frame 2 and the upper end of the diversion baffle 202. The residue filter plate 205 is inclined. During the cooling process of the forging, the coolant flows over the forging and enters the upper part of the cooling platform 1, and then flows into the interior of the coolant return rack 2. As the coolant return rack 2 is inclined, it converges towards the coolant collection chamber 203. During the convergence process, it passes through the residue filter plate 205, which intercepts impurities in the coolant and filters the coolant to prevent impurities in the coolant from entering the coolant return pump 7 and causing blockage of the return pump, which would lead to malfunction of the forging cooling device. The residue generated during forging is collected through the residue collection chamber 204.

[0031] In this embodiment, the left and right ends of the rotary support roller 401 are both provided with support roller limiting flanges 402; the setting of the support roller limiting flanges 402 enables the high-temperature forging to have a limiting effect while rotating above the rotary support roller 401, thereby preventing the high-temperature forging from falling off the side.

[0032] In Example 2, based on Example 1, the coolant delivery frame 6 is an inverted "U"-shaped pipe, and a coolant nozzle 601 is fixedly connected to the inner surface of the coolant delivery frame 6. The forging is surrounded by the "U"-shaped coolant delivery frame 6, and coolant is sprayed onto the surface of the forging through the coolant nozzle 601. When the forging rotates under the drive of the rotary support roller 401, coolant can be circulated and sprayed onto the outer surface of the forging through the coolant delivery frame 6, thereby improving the cooling uniformity of the forging.

[0033] The working principle of this embodiment is as follows: First, the high-temperature forging is placed above and between two rotary support rollers 401 using a fixture, so that the cylindrical forging forms a rolling connection with the two rotary support rollers 401. The forging rotation drive 3 drives the rotary support roller 401 located in front to rotate, so that the forging rotates at a uniform speed above the rotary support roller 401. The coolant return pump 7 is turned on, and the coolant is pumped from the bottom of the coolant collection chamber 203 into the coolant delivery frame 6 through the coolant return pump 7. The coolant is then evenly sprayed onto the forging from three directions through the coolant nozzles 601, cooling the high-temperature forging through liquid cooling. This optimizes the metal microstructure of the forging, transforming the austenite phase at high temperature into the martensite phase at low temperature, thereby significantly improving the hardness and strength of the metal. During the cooling process, the coolant flows over the forging and enters the area above the cooling platform 1, then flows into the coolant return rack 2. As the coolant return rack 2 slopes, it converges into the coolant collection chamber 203. During the convergence process, it passes through the residue filter plate 205, which intercepts impurities in the coolant and filters it. The filtered coolant then flows back into the coolant collection chamber 203 for centralized storage. Meanwhile, the forging residue intercepted by the residue filter plate 205 falls to the right along its slope into the residue collection chamber 204 for storage, preventing impurities in the coolant from entering the coolant return pump 7 and causing blockage and malfunction of the forging cooling device. After cooling, the forging is removed from above the rotary support 4 using tools.
