Description

Technical Field

[0001] The invention belongs to the technical field of forging die cooling, and in particular relates to a cooling device for a forging die of an automobile part. Background Art

[0002] During the forging process, the die is in constant contact with the hot metal billet, causing the die temperature to rise rapidly. Without proper cooling, the die temperature may exceed its tolerance limit, leading to premature failure or damage. Various cooling methods are used for automotive parts forging dies, including natural cooling, blast cooling, and brine cooling.

[0003] The existing cooling devices for forging dies for automotive parts have the following problems:

[0004] Most of the existing devices that use air cooling to cool the mold use the impact force of the air flow to directly contact the mold, so that the air flow carries away the heat of the mold, thereby cooling the mold. However, when the air flow contacts the mold, the high-temperature debris attached to the mold will spread with the flow of the air flow, which will cause burns to the workers. In addition, due to the uneven air flow, the air cooling method of traditional wind cooling devices causes uneven temperature distribution on the mold surface. The uneven temperature distribution will cause the mold to deform and crack, thereby affecting the forming accuracy and surface quality of the accessories. Therefore, it cannot meet the existing demand for cooling devices for forging dies of automotive accessories. Summary of the Invention

[0005] In view of the above situation, in order to overcome the defects of the existing technology, the present invention provides a cooling device for automobile parts forging dies that can not only use the impact force of air-cooled gas to cool the mold and remove impurities on its surface, but also prevent high-temperature impurities that fall off from the mold surface from diffusing with the gas and causing burns to the operators.

[0006] The technical solution adopted in this scheme is as follows: This scheme proposes a cooling device for a forging die of an automobile part, comprising a base, a support frame, an air-cooled cooling mechanism and a flip-type de-dusting mechanism. The support frame is symmetrically arranged on the upper walls at both ends of the base, the air-cooled cooling mechanism is arranged on the support frame, and the flip-type de-dusting mechanism is arranged on the air-cooled cooling mechanism. The air-cooled cooling mechanism includes an air guide mechanism, a windward mechanism and an air return mechanism. The air guide mechanism is arranged at one end of the support frame away from the base, the windward mechanism is arranged on the side of the air guide mechanism away from the support frame, and the return air mechanism is arranged on the side wall of the windward mechanism. The flip-type de-dusting mechanism includes a positioning mechanism and a driving mechanism. The support plate is arranged on the upper wall of the cooling cylinder, and the drive motor is arranged on the upper wall of the base below the cooling cylinder.

[0007] As a further preferred embodiment of the present invention, the air guide mechanism includes an air guide cone, an air extraction pump and an air cooling pipe, the air guide cone is provided through the end of the support frame away from the base, the air guide cone is provided with an opening at one end, the air extraction pump is provided through the end of the support frame close to the base, and the air cooling pipe is provided between the exhaust end of the air extraction pump and the air guide cone; the windward mechanism includes a cooling cylinder, a conduction port and a copper cone, the cooling cylinder is provided between the air guide cones, multiple groups of the conduction ports are provided at the end of the cooling cylinder away from the air guide cone, and the copper cones are symmetrically provided on both sides of the cooling cylinder. The copper cone is arranged inside the air guide cone, and the copper cone is connected to the cooling cylinder; the return air mechanism includes a return air box, a return air duct, an exhaust valve, an exhaust duct, a thermoelectric generator, a rectifier and a conductive copper plate, the return air box is connected between the air guide cones, the return air duct is connected between the bottom walls of the return air box, the exhaust valve is arranged through the inner wall of the support frame, the exhaust duct is connected between the return air duct and the exhaust valve, multiple groups of thermoelectric generators are arranged through the inner wall of the return air box at one end away from the cooling cylinder, the rectifier is arranged on the upper wall of the return air box, and the thermoelectric generator is electrically connected to the rectifier.

[0008] During use, the vacuum pump transports the external air-cooling gas through the air-cooling pipe through the vacuum end to the inside of the air guide cone. The gas flows along the conical cavity formed between the air guide cone and the copper cone. After flowing through the inside of the conical cavity, the gas enters the inside of the return air box. The flow path of the gas forms an angle with the plane where the thermoelectric generator is located. After flowing out of the conical cavity, the gas enters the inside of the return air box and impacts the thermoelectric generator. The thermoelectric generator is located on one side of the return air box and is heated, causing a temperature difference at both ends of the thermoelectric generator. The current generated by the temperature difference inside the thermoelectric generator enters the inside of the rectifier for rectification. An external battery is connected to the rectifier, and the current generated by the thermoelectric generator is transported to the battery for storage. The excess gas enters the exhaust duct through the return air duct, and the exhaust duct discharges the gas through the exhaust valve.

[0009] The top end face of said sliding panel also is provided with an interlocking plate, and the interlocking plate is connected with the interlocking plate of said sliding panel and the interlocking plate, and the interlocking plate is connected with the interlocking plate of said sliding panel.

[0010] When in use, rotate the fixing bolt, the fixing bolt is unscrewed from the inside of the fixing plate, and the extrusion plate is removed from the upper wall of the fixing plate. The extrusion spring is in a compressed state in the initial state, and the automobile parts forging die to be cooled is vertically placed into the slot, and then the extrusion plate is placed on the upper wall of the fixing plate, the rotating plate is fitted with the upper side wall of the automobile parts forging die, and the fixing bolt is rotated and screwed into the inside of the fixing plate. The extrusion spring uses deformation to make the limit shaft slide along the inner wall of the extrusion plate and extend out of the cooling cylinder. The rotating plate is tightly fitted with the upper side wall of the automobile parts forging die, and the automobile parts forging die is fixed inside the cooling cylinder. The drive motor drives the drive shaft to rotate through the power end, and the drive shaft drives the automobile parts forging die to rotate inside the cooling cylinder through the support plate, so that the copper cone cylinder can evenly cool the automobile parts forging die.

[0011] Specifically, a controller is provided on the upper wall of the return air box on one side of the rectifier.

[0012] Wherein, the controller is electrically connected to the thermoelectric generator, the rectifier and the drive motor respectively.

[0013] Preferably, the model of the thermoelectric generator is TEG1-287-1.4-1.5.

[0014] The beneficial effects achieved by adopting the above structure are as follows:

[0015] Compared with the existing technology, this solution adopts a non-contact air cooling structure combined with a rotating impurity removal mechanism. Through the provision of an air-cooling type cooling mechanism and a flip-type impurity removal mechanism, the coordinated use of an air guide mechanism, a windward mechanism, an air return mechanism, a positioning mechanism and a driving mechanism can evenly cool the forging die of automotive parts to avoid defects such as die deformation and cracking. Under the guiding effect of the conical cavity formed by the air guide cone and the copper cone, on the one hand, the contact time between the air-cooling airflow and the copper cone can be prolonged, so that the airflow can take away more heat, and on the other hand, On the one hand, under the guidance of the conical cavity, the gas with increased temperature can impact the inner wall of the return air box equipped with a thermoelectric generator, thereby increasing the temperature difference at both ends of the thermoelectric generator, which is convenient for recovering the energy of the hot gas. When the drive motor drives the forging die of automotive parts to rotate, the energy consumption of the drive motor is reduced. Therefore, under the condition that the air-cooled gas does not contact the die, the impact force of the air-cooled gas can be used to cool the die and remove impurities on its surface, and the high-temperature impurities falling off the die surface can be prevented from diffusing with the gas, which may cause burns to the operators.

[0034] A controller 31 is provided on the upper wall of the return air box 13 on one side of the rectifier 18 .

[0035] The controller 31 is electrically connected to the thermoelectric generator 17 , the rectifier 18 and the drive motor 29 .

[0036] The model of the thermoelectric power generation sheet 17 is TEG1-287-1.4-1.5.

[0037] During specific use, in the initial state, the extrusion spring 27 is in a compressed setting. The extrusion spring 27 uses deformation to drive the rotating plate 26 to extend into the cooling cylinder 9 and be placed. The extrusion plate 24 is in contact with the upper wall of the fixed plate 23. The fixing bolt 33 is screwed into the fixed plate 23. The exhaust valve 15 is connected to the pipe discharged from the outside of the workshop. The suction end of the air pump 6 is connected to the gas pipe entering the workshop. The pipe discharged from the outside of the workshop is on the side of the workshop away from the gas pipe entering the workshop.

[0038] When the forging die for automobile parts needs to be cooled, the fixing bolt 33 is manually rotated, and the fixing bolt 33 is unscrewed from the inside of the fixing plate 23. The extrusion plate 24 is removed from the upper wall of the fixing plate 23, and the forging die for automobile parts to be cooled is vertically placed into the slot 22. Then, the extrusion plate 24 is placed on the upper wall of the fixing plate 23. The rotating plate 26 is fitted with the upper side wall of the forging die for automobile parts. The fixing bolt 33 is rotated and screwed into the inside of the fixing plate 23. The extrusion spring 27 utilizes deformation to make the limit shaft 25 slide along the inner wall of the extrusion plate 24 and extend out of the cooling cylinder 9. The rotating plate 26 is tightly fitted with the upper side wall of the forging die for automobile parts, and the forging die for automobile parts is fixed inside the cooling cylinder 9.

[0039] The controller 31 controls the drive motor 29 to start, and the drive motor 29 drives the drive shaft 30 to rotate through the power end. The drive shaft 30 drives the automobile parts forging die to rotate inside the cooling cylinder 9 through the support plate 21, so that the copper cone cylinder 11 can evenly cool the automobile parts forging die.

[0040] The controller 31 controls the vacuum pump 6 to start, and the vacuum pump 6 delivers the external air-cooling gas through the air-cooling pipe 7 to the inside of the air guide cone 5 through the vacuum end.

After flowing through the inside of the conical cavity, the gas enters the inside of the return air box 13. The flow path of the gas forms an angle with the plane where the thermoelectric power generation sheet 17 is located. After flowing out of the conical cavity, the gas enters the inside of the return air box 13 and impacts the thermoelectric power generation sheet 17. The thermoelectric power generation sheet 17 is located inside the return air box 13. One side is heated, causing a temperature difference at both ends of the thermoelectric power generation sheet 17. The current generated by the temperature difference in the thermoelectric power generation sheet 17 enters the rectifier 18 for rectification. An external battery is connected to the rectifier 18, and the current generated by the thermoelectric power generation sheet 17 is transmitted to the battery for storage. The battery provides energy for the operation of the drive motor 29, reducing the energy consumption of the drive motor 29. The excess gas enters the exhaust pipe 16 through the return air pipe 14, and the exhaust pipe 16 discharges the gas through the exhaust valve 15.

[0041] As the temperature of the automobile parts forging die gradually decreases, the oxides or slag on the surface of the automobile parts forging die will loosen or fall off due to thermal expansion and contraction. In the process of the driving motor 29 driving the automobile parts forging die to rotate through the driving shaft 30, the impurities attached to the surface of the automobile parts forging die fall off under the action of centrifugal force, and the fallen impurities fall into the cooling cylinder 9, preventing high-temperature debris on the surface of the automobile parts forging die from drifting with the air flow and scalding the operators, thereby improving the efficiency of using wind power to cool the automobile parts forging die; just repeat the above operation when using it next time.

[0042] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0043] The above description of the present solution and its implementation methods is non-limiting. The drawings show only one implementation method of the present solution, and the actual structure is not limited thereto. In short, if a person skilled in the art is inspired by this and, without departing from the purpose of the present solution, designs a similar structure and embodiment without creatively designing, they shall fall within the scope of protection of the present solution.
