Description

Technical Field

[0001] The utility model relates to a uniform cooling structure of a forging die, belonging to the technical field of forging die cooling. Background Art

[0002] A forging die is a tool used in the forging process. It is used to heat a metal blank to a certain temperature, and then plastically deform the blank by applying pressure and changing its shape, so as to finally obtain a forged product corresponding to the shape of the die. During the forging process, the die surface is affected by high temperature and high stress. In order to prevent the die from overheating, extend its service life, and ensure the quality of forming, a cooling structure is essential. The existing forging die cooling structure usually cools the die by setting water cooling at the bottom of the die. However, due to the large volume of the forging die, the depth of the die is often large, so the water cooling at the bottom has a poor cooling effect on the top surface of the die. Therefore, heat is easily accumulated on the top of the die, which damages the service life of the die. In view of the problem that when water cooling is set at the bottom of the forging die to cool the die with a large depth, the cooling effect on the top surface of the die is poor, which easily causes heat accumulation on the top of the die and thus damages the service life of the die, a uniform cooling structure for the forging die is developed. By expanding the water cooling cavity wrapping range of the water cooling equipment to the top surface of the forging die, and cooperating with the oblique reinforcement structure inside the cavity, the pressure resistance of the cavity is improved and the die is evenly cooled, thereby alleviating heat accumulation and extending the service life. Summary of the invention

[0003] The technical problem to be solved by the utility model is to provide a uniform cooling structure for a forging die in view of the defects in the prior art, so as to overcome the problem that when water cooling is set at the bottom of the forging die to cool a die with a large depth, the top surface of the die cannot be covered, and the uneven heat dissipation easily generates heat accumulation on the top, thereby damaging the service life of the die.

[0004] To solve this technical problem, the utility model provides a uniform cooling structure for a forging die, comprising a cooling box, a cooling water storage assembly, a heat dissipation fin structure, a heat exchange structure, a spiral water pipe, a vertical reinforcement structure and a diagonal reinforcement structure. The cooling box is a hollow cavity structure, a cooling water storage assembly is arranged on its side, the cooling box and the cooling water storage assembly are connected by a spiral water pipe on the side, and a heat dissipation fin structure is arranged on the surface of the cooling water storage assembly; a heat exchange structure is arranged on the outside of the cooling box, and a vertical reinforcement structure and a diagonal reinforcement structure are arranged inside the cooling box, so that the water cooling cavity wrapping range of the water cooling equipment is expanded to the top surface of the forging die, and cooperates with the diagonal reinforcement structure inside the cavity to make the die evenly cooled.

[0005] The cooling water storage component includes a cold water storage box, a heat dissipation duct and a heat dissipation fan. The cold water storage box is arranged on the side of the cooling box. The cold water storage box has a built-in water pump and a heat dissipation duct in the middle. The heat dissipation duct is connected to the cooling fans at both ends. A number of concave and convex heat dissipation fin structures are evenly distributed on the side of the cold water storage box and inside the heat dissipation duct. Cooling is performed through the heat dissipation duct in the middle of the cold water storage box in conjunction with the heat dissipation fan.

[0006] The heat exchange structure includes a mold placement groove, a water inlet and outlet, and a spiral water pipe. The mold placement groove is opened on the upper surface of the cooling box. The groove body size of the mold placement groove is adapted to the outer size of the forging mold so that the forging mold can be embedded in the mold placement groove. The opening of the mold placement groove is provided with an eaves structure covering the upper surface of the outer edge of the forging mold; a pair of water inlets and outlets are provided on the sides of the cooling box and the cold water storage box, and two spiral water pipes are respectively arranged on both sides of the cooling box and the cold water storage box, and the two ends of the spiral water pipes are respectively connected to the water inlets and outlets of the cooling box and the cold water storage box.

[0007] The spiral water pipe is a hard spiral metal pipe.

[0008] The vertical reinforcement structure includes reinforcement beams and reinforcement columns. The bottom surface of the inner cavity of the cooling box and the lower surface of the mold placement groove are provided with a number of reinforcement beams in opposite positions, and a number of reinforcement columns are longitudinally fixedly connected between the reinforcement beams; the oblique reinforcement structure includes reinforcement inclined surfaces and oblique reinforcement columns. The bottom surface of the inner cavity of the cooling box and the back side of the mold placement groove are both provided with reinforcement inclined surfaces in opposite positions at the corners, and oblique reinforcement columns are fixedly connected between the reinforcement inclined surfaces.

[0009] Beneficial effects: The cooling water storage component of the utility model accelerates the air duct opened in the middle of the water storage tank through a fan, and cooperates with the heat dissipation fin structure to increase the contact area with the air by using the concave and convex outer surface to improve the heat dissipation speed, so that the fan cools the water inside the water storage tank that is not easily in contact with the air, thereby improving the cooling effect. The heat exchange structure evenly wraps the mounting groove of the forging mold, so that the cooling water can dissipate heat uniformly to the outer surface of the mold in all directions, preventing heat accumulation on the top of the mold from damaging the service life of the mold. The spiral water pipe uses the centrifugal force of the rotating water flow to make the water flow closer to the water pipe wall, thereby improving the cooling effect of the liquid. The vertical reinforcement structure and the oblique reinforcement structure disperse the concentrated external force to the beam and transmit it to the reinforcement column, thereby increasing the rigidity of the structure and preventing local stress concentration from causing deformation or damage to the mounting groove.

[0017] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0018] like Figure 1-Figure 6 As shown, the utility model provides a uniform cooling structure for a forging die, comprising a cooling box 1, a cooling water storage component 2, a heat dissipation fin structure 3, a heat exchange structure 4, a spiral water pipe 5, a vertical reinforcement structure 6 and an oblique reinforcement structure 7. The cooling box 1 is a hollow cavity structure, and a cooling water storage component 2 is arranged on its side. The cooling box 1 and the cooling water storage component 2 are connected by the spiral water pipe 5 on the side, and the surface of the cooling water storage component 2 is provided with a heat dissipation fin structure 3; the heat exchange structure 4 is arranged on the outside of the cooling box 1, and a vertical reinforcement structure 6 and an oblique reinforcement structure 7 are arranged inside the cooling box 1, so that the water cooling cavity wrapping range of the water cooling equipment is expanded to the top surface of the forging die, and cooperates with the oblique reinforcement structure 7 inside the cavity to improve the pressure resistance of the cavity, and at the same time, the mold is evenly cooled, heat accumulation is relieved and the service life is extended.

[0019] The cooling water storage component 2 includes a cold water storage box 201, a heat dissipation duct 202 and a heat dissipation fan 203. The cold water storage box 201 is arranged on the side of the cooling box 1. The cold water storage box 201 is equipped with a water pump, a heat dissipation duct 202 is opened in the middle, and heat dissipation fans 203 are connected to both ends of the heat dissipation duct 202. A number of concave-convex heat dissipation fin structures 3 are evenly distributed on the side of the cold water storage box 201 and inside the heat dissipation duct 202. The heat dissipation duct 202 in the middle of the cold water storage box 201 allows the internal water source that was originally difficult to exchange heat with the air to contact with the air, and is cooled in conjunction with the heat dissipation fan 203, thereby improving the cooling effect of the cooling water, thereby improving the cooling efficiency of the water cooling, and increasing the contact area with the air through the concave-convex outer surface of the heat dissipation fin structure 3, thereby improving the heat exchange rate between the cooling water and the air, thereby improving the cooling efficiency of the water cooling.

[0020] The heat exchange structure 4 includes a mold placement groove 401, a water inlet and outlet 402 and a spiral water pipe 5. The mold placement groove 401 is opened on the upper surface of the cooling box 1. The groove size of the mold placement groove 401 is adapted to the outer size of the forging mold, so that the forging mold is just embedded in the mold placement groove 401. The opening of the mold placement groove 401 is provided with an eaves structure covering the upper surface of the outer edge of the forging mold; the sides of the cooling box 1 and the cold water storage box 201 are both provided with a pair of water inlets and outlets 402, and two spiral water pipes 5 are respectively provided on both sides of the cooling box 1 and the cold water storage box 201, and the two ends of the spiral water pipe 5 are respectively connected to the water inlets and outlets 402 of the cooling box 1 and the cold water storage box 201; by evenly wrapping the mold placement groove 4 of the forging mold 01, so that the cooling water can dissipate heat evenly in all directions to the outer surface of the mold, taking into account the upper surface of the mold that cannot be cooled by the original bottom water cooling, making the cooling more even, and preventing heat accumulation on the top of the mold from damaging the service life of the mold. The bending and winding of the spiral water pipe 5 makes the actual length of the water pipe longer than that of the straight pipe. Therefore, when water flows through the spiral water pipe 5, it can contact more of the inner surface of the pipe. At the same time, the rotating water flow causes eddy motion, so that the water source fits more closely to the inner surface of the pipe due to the rotating centrifugal force, thereby jointly improving the heat dissipation speed, and the water flow that has been heat-dissipated is mixed with the water flow that has not been heat-dissipated through rotating stirring, so that the heat is evenly distributed in the water flow, making the cooling of the liquid more even, thereby improving the cooling effect of water cooling.

[0021] The spiral water pipe 5 is a hard spiral metal pipe.

[0022] The vertical reinforcement structure 6 includes a reinforcement beam 601 and a reinforcement column 602. The inner cavity bottom surface of the cooling box 1 and the lower surface of the mold placement groove 401 are provided with a plurality of reinforcement beams 601 in opposite positions. A plurality of reinforcement columns 602 are longitudinally fixedly connected between the reinforcement beams 601. The concentrated external force is dispersed to the surface of the beam through the reinforcement beam 601, and then transmitted to the reinforcement column 602, so as to increase the rigidity of the whole structure and prevent the deformation or damage of the mold placement groove 401 caused by the local stress concentration. The oblique reinforcement structure 7 includes a reinforcement inclined surface 701 and oblique reinforcement columns 702, the bottom surface of the inner cavity of the cooling box 1 and the back surface of the mold placement groove 401 are both provided with oppositely positioned reinforcement slopes 701 at the corners, and oblique reinforcement columns 702 are fixedly connected between each reinforcement slope 701; by providing thickened reinforcement slopes 701, the corner part in the mold placement groove 401 is thickened to prevent breakage when subjected to concentrated force, and the oblique reinforcement columns 702 are used for reinforcement support to absorb the impact force on the reinforcement slopes 701, thereby increasing the firmness of the corners of the mold placement groove 401 to prevent breakage.

[0023] The working steps of using the utility model are as follows:

[0024] First, when the die is pressed, the metal blank heated at high temperature is subjected to pressure from top to bottom in the die, or the metal blank is deformed by the impact force and adapted to the inner space of the forging die. At this time, the impact force from above is transmitted to the bottom surface of the die placement groove 401 through the forging die, and the impact force is evenly dispersed to the surface by the reinforcement beam 601, and then transmitted to the reinforcement column 602 for absorption, thereby increasing the vertical impact resistance of the cavity of the die placement groove 401 to prevent deformation and fracture. At the same time, the corners of the die placement groove 401 are thickened by the reinforcement inclined surface 701 to increase the strength of the corners, and the lateral force on the corners is dispersed and absorbed by the oblique reinforcement column 702 to prevent the corners of the die placement groove 401 from being fractured.

[0025] While the mold is being pressed, the water pump power of the cold water storage box 201 is turned on, and the cold water therein flows into the spiral water pipe 5 from the water inlet and outlet 402. Due to the bending and winding of the spiral shape, the actual length of the water pipe is longer than that of the straight pipe, so that the water can contact with more pipe surfaces when flowing through the pipe, and the centrifugal force generated by the eddy current is close to the inner wall of the spiral water pipe 5 to improve the cooling effect. Then the cooling water enters the cavity inside the cooling box 1, and cools the outer surface of the mold as it is covered by the mold placement groove 401, so that the cooling is more uniform;

[0026] Afterwards, the heated water source is cooled by the spiral water pipe 5 and then returns to the cold water storage tank 201. The cooling fin structure 3 increases the contact area with the air to increase the cooling speed of the water source inside the cold water storage tank 201. The heat dissipation duct 202 opened in the center of the cold water storage tank 201 allows the internal water source that was originally difficult to exchange heat with the air to come into contact with the air, and is cooled with the heat dissipation fan 203 to improve the cooling effect of the cooling water, thereby improving the refrigeration efficiency of the water cooling. The forging mold is continuously and evenly cooled through the above cycle to relieve heat accumulation in the mold and extend its service life.

[0027] Through the above steps, the heat exchange structure 4 evenly wraps the placement groove of the forging die, so that the cooling water can dissipate heat evenly in all directions to the outer surface of the die, preventing heat accumulation on the top of the die from damaging the service life of the die. The vertical reinforcement structure 6 and the oblique reinforcement structure 7 disperse the concentrated external force to the crossbeam and transmit it to the reinforcement column, increasing the rigidity of the structure and preventing local stress concentration from causing deformation or damage to the placement groove. This solves the problem that when water cooling is set at the bottom of the forging die to cool a die with a large depth, the top surface of the die cannot be covered, and uneven heat dissipation is prone to heat accumulation on the top, thereby damaging the service life of the die.

[0028] The utility model solves the problem that when water cooling is arranged at the bottom of a forging die to cool a die with a large depth, the top surface of the die cannot be covered, and uneven heat dissipation easily causes heat accumulation on the top, thereby damaging the service life of the die; a heat exchange structure is used to evenly wrap the placement groove of the forging die, so that cooling water can uniformly dissipate heat to the outer surface of the die in all directions, thereby preventing heat accumulation on the top of the die from damaging the service life of the die; the utility model utilizes the eddy current motion caused by the spiral pipe to make the water source fit closer to the inner wall of the pipe due to the centrifugal force, thereby improving the heat dissipation speed of the water source and further improving the cooling efficiency of the water cooling; the vertical reinforcement structure and the oblique reinforcement structure arranged at the corner of the die wrapped by the placement groove are used to disperse the concentrated external force to the cross beam and transmit it to the reinforcement column, thereby increasing the rigidity of the structure and preventing the placement groove from being deformed or damaged due to local stress concentration.

[0029] The above embodiments of the present invention are merely illustrative and not exclusive, and all modifications within the scope of the present invention or equivalent to the scope of the present invention are encompassed by the present invention.
