[0002] During forging die operation, a spray cooling machine is needed to continuously spray atomized cooling and lubricating agent into the die cavity for cooling and lubrication. For example, existing patent publication number CN220591429U, entitled "A Cavity Cooling and Lubricating Spray Device for Forging Dies," proposes that the present invention includes a water tank body, a spray gun, a liquid storage tank, a diaphragm pump, an air storage tank, a pneumatic stirring pump, and a stirring mechanism.

The diaphragm pump outlet is connected to the storage tank inlet; the spray gun is connected to the water tank body via a sliding mechanism, and the spray gun inlet is connected to the storage tank outlet; the air tank is fixed to the water tank body, and its air outlet is connected to the diaphragm pump and the pneumatic stirring pump respectively; the stirring mechanism is located inside the water tank body; this utility model uses the diaphragm pump, storage tank, and spray gun to quickly and evenly spray the cooling lubricant onto the mold surface, avoiding the evaporation of the cooling lubricant due to high temperature, improving the lubrication effect of the lubricating oil, and increasing the qualification rate of the produced products.

[0003] However, in the implementation of the technology disclosed in the above patent, the displacement spraying of the spray gun and the stirring of the cooling lubricant require two motors to drive the process, resulting in poor mechanical linkage and thus low energy efficiency of the device. Therefore, it is necessary to propose a spray cooling machine for cooling forging dies to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a spray cooling machine for cooling forging dies, so as to solve the problem mentioned in the background art that when the existing technology is used to spray cool and lubricate forging dies, the displacement spraying of the spray gun and the stirring of the cooling lubricant need to be driven by two motors, resulting in poor mechanical linkage and thus low energy efficiency of the device.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a spray cooling machine for cooling forging dies, comprising a housing, a water tank inside the housing, a guide rail fixedly mounted at the rear end of the top of the housing, a movable block slidably mounted on the guide rail, an extension pipe mounted on the top of the movable block via a lifting assembly, a spray gun mounted at the end of the extension pipe, a housing fixedly mounted at the left end of the housing, a conveying assembly between the housing and the extension pipe, a hydraulic cylinder fixedly mounted between the top of the housing and the housing, the telescopic end of the hydraulic cylinder being fixedly connected to the movable block, and a stirring assembly mounted in the middle of the top of the water tank;

[0006] The stirring assembly includes two support gears, which are rotatably mounted on the left and right sides of the top of the water tank, respectively. A synchronous belt is rotatably mounted between the two support gears. The inner wall of the synchronous belt is fixedly provided with internal teeth, which mesh with the support gears. A fixed plate is fixedly connected between the left and right inner walls of the top of the water tank. A stirring shaft is rotatably mounted at the bottom of the fixed plate. The upper end of the stirring shaft movably passes through the upper surface of the fixed plate and is fixedly connected with a driven gear, which meshes with the internal teeth. A connecting rod is fixedly mounted on the side of the movable block. A first locking tooth is fixedly mounted at the end of the connecting rod. A second locking tooth is fixedly mounted on the outer wall of the hydraulic cylinder. The first and second locking teeth mesh with each other.

[0007] Preferably, a limiting disk is fixedly provided at the upper end of the supporting gear.

[0008] Preferably, the conveying assembly includes a conveying pump disposed inside the chassis. The inlet end of the conveying pump is connected to a water tank via an inlet pipe. The outlet end of the conveying pump is connected to an outlet pipe that penetrates the outer wall of the chassis and is fixedly connected to a flexible hose. The other end of the flexible hose is fixedly connected to an extension pipe.

[0009] The lifting assembly includes an electric push rod fixedly mounted on the top of the movable block, with the telescopic end of the electric push rod fixedly connected to the lifting block, and the extension tube fixed to the side of the lifting block.

[0010] Preferably, there are several stirring shafts arranged at equal intervals.

[0011] Preferably, a control panel is provided on the top of the chassis, and the hydraulic cylinder, electric push rod and delivery pump are all electrically connected to the control panel.

[0012] Preferably, the fixing plate is located in the middle of the top of the water tank.

[0013] The technical effects and advantages of this utility model are as follows:

[0014] 1. This utility model only requires the activation of the hydraulic cylinder to achieve the displacement and spraying of the spray gun while simultaneously stirring the cooling lubricant. This solves the problem that in the existing technology for spray cooling and lubrication of forging dies, the displacement and spraying of the spray gun and the stirring of the cooling lubricant require two motors to drive, resulting in poor mechanical linkage and thus low energy efficiency of the device.

[0015] 2. In the process of using this utility model, forging graphite emulsion and water are added into the interior of the water tank to form a cooling and lubricating liquid mixture. The delivery pump is started, and the cooling and lubricating liquid inside the water tank passes through the inlet pipe, outlet pipe, hose and extension pipe in sequence before being sprayed out from the spray gun. The atomized cooling and lubricating liquid is sprayed into the cavity of the forging mold for cooling and lubrication. At the same time, the hydraulic cylinder is started to push the movable block to move on the guide rail, which in turn drives the lifting component, extension pipe and spray gun to move, thereby uniformly and comprehensively cooling and lubricating the cavity of the forging mold and improving the cooling and lubrication effect.

[0016] 3. After the hydraulic cylinder is started, the movable block drives the connecting rod and the first clasp to move, which in turn drives the second clasp to move, which in turn drives the synchronous belt to rotate between the two support gears, which in turn drives multiple driven gears to rotate synchronously, and finally drives multiple stirring shafts to rotate synchronously to stir the coolant and lubricant. The uniformly stirred coolant and lubricant is sprayed onto the cavity to effectively improve product quality.

[0017] 4. When the height of the forging die is different, the electric push rod is activated to drive the lifting block to move up and down, which in turn drives the extension tube and spray gun to move up and down to accommodate forging dies of different heights, thus expanding the applicability of the lifting device.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] This utility model provides, for example Figures 1-5 The spray cooling machine for cooling forging dies shown includes a housing 1, with a water tank 2 inside the housing 1. A guide rail 5 is fixedly installed at the rear end of the top of the housing 1, and a movable block 6 is slidably installed on the guide rail 5. An extension pipe 8 is installed on the top of the movable block 6 via a lifting assembly, and a spray gun 9 is installed at the end of the extension pipe 8. A machine box 3 is fixedly installed at the left end of the housing 1, and a conveying assembly is installed between the machine box 3 and the extension pipe 8. A hydraulic cylinder 4 is fixedly installed between the top of the housing 1 and the top of the machine box 3, and the telescopic end of the hydraulic cylinder 4 is fixedly connected to the movable block 6. A stirring assembly is installed in the middle of the top of the water tank 2.

[0026] The stirring assembly includes two support gears, which are rotatably mounted on the left and right sides of the top of the water tank 2. A synchronous belt 14 is rotatably mounted between the two support gears. An internal tooth 15 is fixedly mounted on the inner wall of the synchronous belt 14, and the internal tooth 15 meshes with the support gear. A fixed plate 17 is fixedly connected between the left and right inner walls of the top of the water tank 2. A stirring shaft 19 is rotatably mounted on the bottom of the fixed plate 17. Several stirring shafts 19 are equidistantly arranged. The upper end of the stirring shaft 19 movably penetrates the upper surface of the fixed plate 17 and is fixedly connected to a driven gear 18, which meshes with the internal tooth 15. A connecting rod 16 is fixedly mounted on the side of the movable block 6. A first locking tooth is fixedly mounted on the end of the connecting rod 16. A second locking tooth is fixedly mounted on the outer wall of the hydraulic cylinder 4. The first and second locking teeth mesh with each other.

[0027] The conveying assembly includes a conveying pump 10 installed inside the housing 3. The inlet end of the conveying pump 10 is connected to the water tank 2 via an inlet pipe. The outlet end of the conveying pump 10 is connected to an outlet pipe, which passes through the outer wall of the housing 3 and is fixedly connected to a hose 11. The other end of the hose 11 is fixedly connected to an extension pipe 8.

[0028] Specifically, in the process of using this utility model, forging graphite emulsion and water are added into the interior of the water tank 2 to form a cooling and lubricating liquid mixture. The delivery pump 10 is started, and the cooling and lubricating liquid inside the water tank 2 passes through the inlet pipe, outlet pipe, hose 11 and extension pipe 8 in sequence before being sprayed out from the spray gun 9. The atomized cooling and lubricating liquid is sprayed into the cavity of the forging mold to cool and lubricate it. At the same time, the hydraulic cylinder 4 is started to push the movable block 6 to move on the guide rail 5, thereby driving the lifting component, extension pipe 8 and spray gun 9 to move, so as to uniformly and comprehensively cool and lubricate the cavity of the forging mold and improve the cooling and lubrication effect.

[0029] In addition, after the hydraulic cylinder 4 is started, the movable block 6 drives the connecting rod 16 and the first clasp tooth to move, which in turn drives the second clasp tooth to move, which in turn drives the synchronous belt 14 to rotate between the two support gears, which in turn drives multiple driven gears 18 to rotate synchronously, and finally drives multiple stirring shafts 19 to rotate synchronously, stirring the coolant and lubricant. The uniformly stirred coolant and lubricant is sprayed onto the cavity, effectively improving product quality.

[0030] Therefore, this utility model only requires the activation of the hydraulic cylinder 4 to achieve the displacement spraying of the spray gun 9 while simultaneously stirring the cooling lubricant. This solves the problem that in the prior art, when spraying cooling lubricant on forging dies, the displacement spraying of the spray gun 9 and the stirring of the cooling lubricant require two motors to drive, resulting in poor mechanical linkage and consequently low energy efficiency of the device.

[0031] Furthermore, the lifting assembly includes an electric push rod 7 fixedly mounted on the top of the movable block 6. The telescopic end of the electric push rod 7 is fixedly connected to the lifting block, and the extension tube 8 is fixed to the side of the lifting block. When the height of the forging mold is different, the electric push rod 7 is activated to drive the lifting block to move up and down, which in turn drives the extension tube 8 and the spray gun 9 to move up and down to accommodate forging molds of different heights, thus expanding the applicability of the lifting device.

[0032] Furthermore, a limiting disk 13 is fixedly installed at the upper end of the support gear, and the timing belt 14 is limited by the setting of the limiting disk 13.

[0033] Furthermore, a control panel 12 is provided on the top of the casing 3. The hydraulic cylinder 4, electric push rod 7, and delivery pump 10 are all electrically connected to the control panel 12. The connection circuit diagram of the hydraulic cylinder 4, electric push rod 7, delivery pump 10, and control panel 12 in this utility model is common knowledge in the existing field. The required model is selected according to the specific situation. Therefore, this utility model will not elaborate further on the connection circuit diagram and model of the hydraulic cylinder 4, electric push rod 7, delivery pump 10, and control panel 12.

[0034] Working Principle: During use, this invention involves mixing forging graphite emulsion with water in a water tank 2 to form a cooling and lubricating liquid mixture. The delivery pump 10 is activated, and the cooling and lubricating liquid inside the water tank 2 passes sequentially through the inlet pipe, outlet pipe, hose 11, and extension pipe 8 before being sprayed out from the spray gun 9. This atomized cooling and lubricating liquid is sprayed into the cavity of the forging mold for cooling and lubrication. Simultaneously, the hydraulic cylinder 4 is activated, pushing the movable block 6 to move on the guide rail 5, which in turn moves the lifting assembly, extension pipe 8, and spray gun 9, thus uniformly and comprehensively cooling and lubricating the cavity of the forging mold. In addition, after the hydraulic cylinder 4 is activated, the movable block 6 drives the connecting rod 16 and the first clasp tooth to move, which in turn drives the second clasp tooth to move, which in turn drives the synchronous belt 14 to rotate between the two support gears, which in turn drives multiple driven gears 18 to rotate synchronously, and finally drives multiple stirring shafts 19 to rotate synchronously, stirring the coolant and lubricant. The uniformly stirred coolant and lubricant is sprayed onto the cavity, which effectively improves the product quality. Thus, only the hydraulic cylinder 4 needs to be activated to achieve the displacement and spraying of the spray gun 9, while also stirring the coolant and lubricant. The mechanical linkage is high, and the energy efficiency of the device is improved.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
