Description

Technical Field

[0001] The present invention relates to the technical field of cooling devices, in particular to a stamping liquid cooling device. Background Art

[0002] Automobiles are called "machines that change the world". Due to the strong industrial correlation of the automobile industry, it is regarded as an important symbol of a country's economic development level. Automobiles have four major processes, and stamping process is the most important of the four processes and also the first of the four processes. Stamping is a forming process that uses a press and a die to apply external force to plates, strips, pipes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining workpieces of the desired shape and size. Stamping and forging are both plastic processing, or pressure processing, collectively known as forging. The blanks for stamping are mainly hot-rolled and cold-rolled steel plates and strips. 60% to 70% of the world's steel is plate material, most of which is made into finished products through stamping. Automobile bodies, chassis, fuel tanks, radiators, boiler drums, etc. are all processed by stamping. Stamping fluid, also known as stamping oil, stamping lubricant or stamping coolant, is a liquid medium commonly used in automotive stamping processes. It forms a lubricating film between the punch, die and plate, reducing direct friction on the metal surface and reducing wear on the workpiece and die. The stamping process will generate local high temperatures, and the stamping fluid can take away some of the heat to prevent overheating of the die and material. The stamping fluid can also remove small particles of metal debris, oxide scale and other impurities during high-speed or multiple stamping. For example, a stamping liquid cooling device of "CN220825389U" includes a stamping liquid recovery box, a liquid inlet pipe is connected to the middle of the left side of the top of the stamping liquid recovery box, a first control valve is provided on the liquid inlet pipe, a liquid outlet pipe is connected to the middle of the left bottom of the stamping liquid recovery box, a second control valve is provided on the liquid outlet pipe, a square port and a semiconductor refrigeration plate are provided on the left side of the inner cavity of the stamping liquid recovery box, the square port is opened on the stamping liquid recovery box, the first control valve is opened to recover the stamping liquid into the stamping liquid recovery box, the semiconductor refrigeration plate is turned on, and the stamping liquid is refrigerated and cooled by the cold end of the semiconductor refrigeration plate, the hydraulic pump is turned on, the stamping liquid is extracted through the first conduit, and is re-guided to the stamping liquid recovery box through the second conduit, the circular hole and the through hole, so that the stamping liquid circulates, the stamping liquid is cooled more fully, thereby enhancing the cooling effect of the coolant, and the second control valve is opened to guide the cooled stamping liquid out; In actual use, when the speed of the automobile production line is high, the punching frequency is high, or the punching depth is relatively large, a large amount of heat will be generated at the contact surface between the die and the workpiece. If the temperature is too high, it may damage the lubricating performance of the punching fluid and exacerbate the wear of the punching die. At this time, a circulating cooling system is usually designed to keep the punching fluid at about 30-40 °C to avoid the degradation of the lubricant caused by overheating. As shown in the above patent, the punching fluid is generally recycled, transported from the liquid tank to the punching station through a circulating pump, and then returned to the same liquid tank or another centralized liquid storage tank, and cooled; However, in the prior art, before cooling the punching fluid, it needs to be filtered, and the filter screen or filter plate after filtration needs to be disassembled and cleaned. If not cleaned for a long time, it is easy to cause the filter screen to be blocked, resulting in poor circulation of the coolant. In addition, during the cooling process, the flow range of the punching fluid is small. When contacting the condensing pipe, it is easy to cause poor condensation effect of the punching fluid at a position far from the condensing pipe locally, resulting in uneven heat exchange, causing local overheating and increased wear of the tool or punching part, and reducing production efficiency. Summary of the Invention

[0003] In view of the above existing problems, the present invention is proposed.

[0004] The purpose of the present invention is to solve the problems of inconvenient cleaning of the filter plate and uneven condensation of the punching fluid in the prior art.

[0005] To solve the above technical problems, the present invention provides the following technical solutions: On the one hand, the present invention provides a stamping fluid cooling device, which includes a storage tank and a partition plate. The storage tank is divided into an oil inlet chamber and a cooling chamber by the partition plate. The feeding end of the oil inlet chamber is connected to the coolant recovery device of the punching machine through a feeding pipe. The output end of the cooling chamber is communicated with a spray head through a discharging pipe. The spray head is used to be arranged at a position close to the stamping tool of the punching machine. Above the middle of the inner part of the storage tank on one side of the partition plate, there is a fixing plate. The oil inlet chamber is located above the fixing plate. The space of the storage tank below the fixing plate is a slag chamber. On the partition plate at the oil inlet chamber, there is a nozzle communicating with the cooling chamber. The height of the stamping fluid in the cooling chamber is lower than the height of the fixing plate. On the fixing plate, there is a circular frame communicating with the slag chamber. The outer wall of the lower part of the circular frame is hermetically magnetically attracted with a slag tray. One side of the slag tray is rotationally connected to the circular frame. The slag tray is a magnet structure. A filter screen is arranged in the oil inlet chamber. A drainage roller is rotatably arranged in the oil inlet chamber on one side of the nozzle. The drainage roller is located between the filter screen and the nozzle. The output end of the nozzle extends to the lower part inside the cooling chamber through a hose. A turntable is rotatably arranged at the lower part inside the cooling chamber. The lower end of the hose is located above the turntable. An inner condenser pipe is arranged above the turntable. An outer condenser pipe is arranged on the outer wall of the storage tank. Both ends of the outer condenser pipe extend into the cooling chamber and are hermetically and rotationally communicated with the end face of the inner condenser pipe. The coolant recovered from the coolant recovery device of the punching machine is introduced into the interior from above the oil inlet chamber. At this time, the coolant contains debris and residues generated during the stamping process. The magnetic metal debris in the coolant is adsorbed by the slag tray, while the liquid passes through the filter screen and is discharged into the cooling chamber. Other debris not magnetically adsorbed by the slag tray is blocked outside by the filter screen. After a period of time, when the feeding into the oil inlet chamber is paused, the debris will gradually settle in the slag tray under the action of gravity, which is convenient for cleaning. During cleaning, the slag tray is rotated to open. After opening, the slag tray is powered off and loses magnetism. After the slag tray is flipped, the residues in the slag tray can be shaken off into the lower slag chamber, which is convenient for the staff to take out the slag. After discharging the slag, the slag tray is rotated to reset and magnetically adsorbed and sealed with the circular frame. After magnetic adsorption, the slag tray is powered on and has magnetism, which is convenient for magnetic debris to be adsorbed to it. The stamping fluid passing through the filter screen can smoothly pass through the nozzle and the hose and enter the cooling chamber under the push of the drainage roller. The liquid discharged from the hose has a certain impact force, which can push the turntable to rotate self-rotationally. And the cooling chamber is filled with stamping fluid, which can push the turntable to rotate slowly. The rotation of the turntable drives the inner condenser pipe above to rotate, which can accelerate the mixing of the stamping fluid in the cooling chamber and ensure that the cooling temperature of each part in the cooling chamber by the inner condenser pipe is as the same as possible. The setting of the outer condenser pipe can lead out the condensate after heat exchange of the inner condenser pipe, cool it down and then introduce it again to ensure the cooling quality. The hot stamping fluid led out by the hose sprays out towards the center position of the turntable. The fan blades directly above the inner condenser pipe can further accelerate the discharge of heat.

[0006] Furthermore, the turntable includes an upper seat, a lower seat and blades, the lower seat is rotatably connected to the lower inside of the storage box, a plurality of blades are provided and are inclinedly arranged between the upper seat and the lower seat, and a plurality of blades are annularly spaced and arranged on the lower seat, the diameter of the upper seat is adapted to the outer diameter of the inner condenser tube, and the diameter of the upper seat is smaller than the diameter of the lower seat, the lower end of the hose is located directly above the blades and is arranged toward the center of the turntable, when the punching fluid is discharged from the lower end of the hose, the impact force brought by the liquid will drive the blades to rotate, and due to the rotation of the lower seat and the storage box, the turntable as a whole can be driven to rotate, wherein the height of the punching fluid in the cooling chamber is kept lower than the oil inlet chamber, creating a height difference with the oil inlet chamber, so that the punching fluid in the oil inlet chamber can enter smoothly.

[0007] Furthermore, a plurality of balls are rotatably provided at the lower edge of the lower seat, and the lower portion of the balls is rollingly connected to the lower portion of the interior of the storage box. An inner shaft is provided at the center position below the lower seat, and a fixed shaft is provided at the lower portion of the interior of the storage box. The lower end of the inner shaft is rotatably provided in the fixed shaft. The provision of the balls allows the turntable to rotate more smoothly.

[0008] Furthermore, the feed end and the discharge end of the outer condenser tube respectively pass through the side of the storage box and are connected to the lower end and the upper end of the inner condenser tube respectively. The end faces of both ends of the outer condenser tube are respectively connected to the end face of the inner condenser tube in a sealed and rotatable manner through a sealing adapter sleeve.

[0009] Furthermore, the upper seat is set as a hollow structure, and a first bevel gear is rotatably provided at the center position above the lower seat, a second bevel gear and a third bevel gear are rotatably provided on the feed end of the outer condenser tube and the sealing adapter sleeve below, and a fourth bevel gear is linked to the outer wall of the lower end of the inner condenser tube, the first bevel gear is meshed with the second bevel gear, the second bevel gear and the third bevel gear are linked through a chain, and the third bevel gear is meshed with the fourth bevel gear. When the turntable rotates, it drives the first bevel gear to rotate, and then drives the second bevel gear, the third bevel gear and the fourth bevel gear to rotate in turn, thereby realizing the self-rotation of the inner condenser tube.

[0010] Furthermore, the outer condenser is wound and laid on the outer wall of the storage box, the outer condenser is connected to a first pump body, a through groove is provided on the side wall of the storage box located just above the inner condenser, and fan blades are rotatably provided on the storage box above the through groove. When the temperature of the cooling chamber is high, the fan blades can be powered on to drive the rotation, which can accelerate internal heat dissipation, quickly move heat upward, and part of the heat is absorbed by the inner condenser to achieve a rapid cooling effect.

[0011] Further, both ends of the drainage roller are rotatably arranged on the inner wall of the storage box. The drainage roller is driven to rotate by a motor. A plurality of flapping blades are arranged on the side wall of the drainage roller. The shortest distance between the drainage roller and the filter screen is less than the width of the flapping blade. The shortest distance between the flapping blade and the nozzle is adapted to the width of the flapping blade. During the process of driving the drainage roller to rotate by the motor, the stamping liquid filtered by the filter screen is pushed to the nozzle under the action of the rotation of the flapping blade, forcing the liquid to be discharged from the nozzle. In addition, since the shortest distance between the drainage roller and the filter screen is less than the width of the flapping blade, when the flapping blade passes through the filter screen, it will flap the filter screen to make it vibrate, and the debris attached to the filter screen can be shaken off to prevent blockage.

[0012] Further, a discharge chute is formed on the fixed plate. The circular frame is arranged below the discharge chute. One side of the slag tray is rotatably connected to the lower part of the circular frame through a rotating shaft. The inner edge of the slag tray is hermetically magnetically connected to the circular frame. A long gear is arranged on the end face of the rotating shaft. A toothed plate is meshed and arranged below the long gear. The toothed plate is slidably arranged below the fixed plate. One end of the toothed plate penetrates through the side wall of the storage box and extends outside. By pushing and pulling the outer end of the toothed plate arranged outside, the long gear can be driven to rotate, and then the slag tray can be driven to turn over or close with the circular frame for discharging. Among them, a first conductive sheet is arranged at the part of the circular frame that fits with the slag tray, and a second conductive sheet is arranged on the slag tray. The first conductive sheet is electrically connected to an external power supply. When the first conductive sheet and the second conductive sheet are in contact, the slag tray is electrified to generate magnetism, and vice versa, the power is cut off and the magnetism is lost to facilitate discharging.

[0013] Further, a telescopic strip is arranged on the side away from the rotating shaft above the discharge chute. A lining is laid on the inner wall of the slag tray. One end of the telescopic strip is assembled and connected to the central position of the lining. When the slag tray rotates and opens, the telescopic strip pulls the lining to separate from the slag tray, facilitating the slag located on the lining to fall.

[0014] The beneficial effects of the present invention are as follows: 1. The coolant recovered from the coolant recovery device of the punching machine in the present invention is introduced into the interior from above the oil inlet cavity. At this time, the coolant contains debris and residues generated during the stamping process. The magnetic metal debris in the coolant is adsorbed by the slag tray, while the liquid passes through the filter screen and is discharged to the cooling cavity. Other debris that is not magnetically adsorbed by the slag tray is blocked outside the filter screen. After a period of time, when adding materials into the oil inlet cavity is paused, the debris will gradually settle in the slag tray under the action of gravity, which is convenient for cleaning.

[0015] 2. In the present invention, the slag tray is rotated and opened. After opening, the slag tray is powered off and loses magnetism. After the slag tray is turned over, the residues in the slag tray can be shaken off into the slag cavity below, facilitating the staff to take out the slag. After discharging, the slag tray is rotated and reset, and is magnetically adsorbed and sealed with the circular frame. After magnetic adsorption, the slag tray is electrified and has magnetism, which is convenient for magnetic debris to be adsorbed to it.

[0016] 3. The stamping fluid passing through the filter screen can smoothly pass through the nozzle and the hose under the push of the drainage roller and enter the cooling chamber. The liquid discharged from the hose has a certain impact force, which can drive the turntable to rotate. Moreover, the cooling chamber is filled with stamping fluid, which can push the turntable to rotate slowly. The rotation of the turntable drives the inner condensing pipe above to rotate, which can accelerate the mixing of the stamping fluid in the cooling chamber and ensure that the cooling temperature of each part in the cooling chamber by the inner condensing pipe is as consistent as possible. The setting of the outer condensing pipe can lead out the condensed liquid after heat exchange by the inner condensing pipe, cool it down and then introduce it again to ensure the cooling quality. The hot stamping fluid led out by the hose sprays towards the center position of the turntable.

[0017] 4. The fan blades arranged directly above the inner condensing pipe in the present invention can further accelerate the heat dissipation and improve the heat dissipation efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In the following description, many specific details are set forth to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Those skilled in the art can make similar promotions without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below.

[0023] Secondly, as referred to herein, "an embodiment" or "embodiment" means a specific feature, structure or characteristic that can be included in at least one implementation manner of the present invention. The appearances of "in an embodiment" in different places in this specification do not all refer to the same embodiment, nor are they separate or alternative embodiments that exclude each other with other embodiments.

[0024] Please refer to Figures 1 - 8, the present invention provides a technical solution: a stamping fluid cooling device, including a storage tank 1 and a partition 2. The storage tank 1 is divided into an oil inlet chamber 3 and a cooling chamber 4 by the partition 2. The feed end of the oil inlet chamber 3 is connected to the coolant recovery device of the punching machine through a feed pipe 511. The output end of the cooling chamber 4 is connected to a spray head 513 through a discharge pipe 512. The spray head 513 is used to be arranged at a position close to the stamping tool of the punching machine. Above the middle of the inner part of the storage tank 1 on one side of the partition 2, there is a fixing plate 611. The oil inlet chamber 3 is located above the fixing plate 611. The space of the storage tank 1 below the fixing plate 611 is a slag chamber 612. On the partition 2 at the oil inlet chamber 3, there is a nozzle 613 communicating with the cooling chamber 4. The height of the stamping fluid in the cooling chamber 4 is lower than the height of the fixing plate 611. On the fixing plate 611, there is a circular frame 614 communicating with the slag chamber 612. The outer wall of the lower part of the circular frame 614 is hermetically magnetically attracted with a slag tray 615. One side of the slag tray 615 is rotatably connected to the circular frame 614. The slag tray 615 is a magnet structure. In the oil inlet chamber 3, there is a filter screen 616. In the oil inlet chamber 3 on one side of the nozzle 613, there is a drainage roller 617 rotatably arranged. The drainage roller 617 is located between the filter screen 616 and the nozzle 613. The output end of the nozzle 613 extends to the lower part inside the cooling chamber 4 through a hose 7. Inside the lower part of the cooling chamber 4, there is a turntable 811 rotatably arranged. The lower end of the hose 7 is located above the turntable 811. Above the turntable 811, there is an inner condensing pipe 812. On the outer wall of the storage tank 1, there is an outer condensing pipe 813. Both ends of the outer condensing pipe 813 extend to the inside of the cooling chamber 4 and are hermetically rotatably connected to the end face of the inner condensing pipe 812.

[0025] As Figures 1 - 8 shown, the turntable 811 includes an upper seat 911, a lower seat 912 and blades 913. The lower seat 912 is rotatably connected to the lower part inside the storage tank 1. There are multiple blades 913 which are inclined and arranged between the upper seat 911 and the lower seat 912. The multiple blades 913 are annularly and spacedly distributed on the lower seat 912. The diameter of the upper seat 911 is adapted to the outer diameter of the inner condensing pipe 812, and the diameter of the upper seat 911 is smaller than the diameter of the lower seat 912. The lower end of the hose 7 is located directly above the blade 913 and is arranged towards the center position of the turntable 811. When the stamping fluid is discharged from the lower end of the hose 7, the impact force brought by the liquid will push the blade 913 to rotate. Since the lower seat 912 rotates with the storage tank 1, the whole turntable 811 can be driven to rotate. Among them, the height of the stamping fluid in the cooling chamber 4 is kept lower than that in the oil inlet chamber 3, generating a height difference with the oil inlet chamber 3, so that the stamping fluid in the oil inlet chamber 3 can smoothly enter.

[0026] As Figures 1 - 8As shown, a plurality of balls 914 are rotatably provided at the lower edge of the lower seat 912, and the lower portion of the balls 914 is rollingly connected to the lower interior of the storage box 1. An inner shaft 915 is provided at the center position below the lower seat 912, and a fixed shaft 916 is provided at the lower interior of the storage box 1. The lower end of the inner shaft 915 is rotatably provided within the fixed shaft 916. The provision of the balls 914 allows the turntable 811 to rotate more smoothly.

[0027] like Figures 1 - 8 As shown, the feed end and the discharge end of the outer condenser tube 813 respectively pass through the side of the storage box 1 and are connected to the lower end and the upper end of the inner condenser tube 812 respectively. The end faces of the outer condenser tube 813 are respectively sealed and rotatably connected to the end faces of the inner condenser tube 812 through the sealing adapter sleeve 10.

[0028] like Figures 1 - 8 As shown, the upper seat 911 is a hollow structure, and a first bevel gear 111 is rotatably provided at the center position above the lower seat 912, a second bevel gear 112 and a third bevel gear 113 are rotatably provided on the feed end of the outer condenser 813 and the sealing adapter sleeve 10 below, and a fourth bevel gear 114 is linked to the outer wall of the lower end of the inner condenser 812, the first bevel gear 111 is meshed with the second bevel gear 112, the second bevel gear 112 and the third bevel gear 113 are linked through a chain, and the third bevel gear 113 is meshed with the fourth bevel gear 114. When the turntable 811 rotates, it drives the first bevel gear 111 to rotate, and then drives the second bevel gear 112, the third bevel gear 113 and the fourth bevel gear 114 to rotate in turn, thereby realizing the self-rotation of the inner condenser 812.

[0029] like Figures 1 - 8 As shown, the outer condenser 813 is wound and laid on the outer wall of the storage box 1, and the first pump body 121 is connected to the outer condenser 813. A through groove 122 is provided on the side wall of the storage box 1 just above the inner condenser 812, and a fan blade 123 is rotated on the storage box 1 above the through groove 122. When the temperature of the cooling chamber 4 is high, the fan blade 123 can be powered on to drive the rotation, which can accelerate the internal heat dissipation, and the heat can be quickly moved upward. Part of the heat is absorbed by the inner condenser 812 to achieve a rapid cooling effect.

[0030] like Figures 1 - 8As shown in the figure, both ends of the drainage roller 617 are rotatably arranged on the inner wall of the storage tank 1. The drainage roller 617 is driven to rotate by the motor 211. A plurality of beating blades 212 are provided on the side wall of the drainage roller 617. The shortest distance between the drainage roller 617 and the filter screen 616 is less than the width of the beating blade 212. The shortest distance between the beating blade 212 and the nozzle 613 is adapted to the width of the beating blade 212. During the process of driving the drainage roller 617 to rotate by the motor 211, the stamping liquid filtered by the filter screen 616 is pushed to the nozzle 613 under the rotation of the beating blade 212, forcing the liquid to be discharged from the nozzle 613. In addition, since the shortest distance between the drainage roller 617 and the filter screen 616 is less than the width of the beating blade 212, when the beating blade 212 passes through the filter screen 616, it will beat the filter screen 616 to make it vibrate, and the debris attached to the filter screen 616 can be shaken off to prevent blockage.

[0031] As Figures 1 - 8 shown in the figure, a discharge chute 221 is provided on the fixing plate 611. The circular frame 614 is arranged below the discharge chute 221. One side of the slag material support 615 is rotatably connected to the lower part of the circular frame 614 through a rotating shaft 222. The inner edge of the slag material support 615 is hermetically magnetically connected to the circular frame 614. A long gear 223 is provided on the end face of the rotating shaft 222. A rack 224 is meshed below the long gear 223. The rack 224 is slidably arranged below the fixing plate 611. One end of the rack 224 penetrates through the side wall of the storage tank 1 and extends outside. By pushing and pulling the outer end of the rack 224, the long gear 223 can be driven to rotate, and then the slag material support 615 can be driven to turn over or close with the circular frame 614 for discharging materials. Among them, a first conductive sheet is provided at the part of the circular frame 614 that fits with the slag material support 615, and a second conductive sheet is provided on the slag material support 615. The first conductive sheet is electrically connected to an external power supply. When the first conductive sheet and the second conductive sheet are in contact, the slag material support 615 is electrified to generate magnetism, and vice versa, it is de-energized and loses magnetism for easy discharging.

[0032] As Figures 1 - 8 shown in the figure, a telescopic strip 231 is provided above the discharge chute 221 on the side away from the rotating shaft 222. A lining 232 is laid on the inner wall of the slag material support 615. One end of the telescopic strip 231 is assembled and connected to the central position of the lining 232. When the slag material support 615 rotates and opens, the telescopic strip 231 pulls the lining 232 to separate from the slag material support 615, facilitating the dropping of the slag material located on the lining 232.

[0033] Working principle: The coolant recovered from the coolant recovery device of the punching machine is introduced into the interior from above the oil inlet chamber 3. At this time, the coolant contains debris residues generated during the stamping process. The magnetic metal debris in the coolant is adsorbed by the slag holder 615, while the liquid passes through the filter screen 616 and is discharged into the cooling chamber 4. Other debris that is not magnetically adsorbed by the slag holder 615 is blocked outside by the filter screen 616. After a period of time, when the feeding into the oil inlet chamber 3 is paused, the debris will gradually settle in the slag holder 615 under the action of gravity, which is convenient for cleaning. During cleaning, the slag holder 615 is rotated to open. After opening, the slag holder 615 is powered off and loses its magnetism. After the slag holder 615 is flipped, the residues in the slag holder 615 can be shaken off into the slag chamber 612 below, which is convenient for the staff to take out the slag. After discharging the slag, the slag holder 615 is rotated to reset and is magnetically sealed and installed with the circular frame 614. After magnetic attraction, the slag holder 615 is powered on and has magnetism, which is convenient for magnetic debris to be adsorbed to it. The stamping liquid passing through the filter screen 616 can smoothly pass through the nozzle 613 and the hose 7 under the push of the drainage roller 617 and enter the cooling chamber 4. The liquid discharged from the hose 7 has a certain impact force, which can drive the turntable 811 to rotate. Moreover, the cooling chamber 4 is filled with stamping liquid, which can push the turntable 811 to rotate slowly. The rotation of the turntable 811 drives the inner condenser tube 812 above to rotate, which can accelerate the mixing of the stamping liquid in the cooling chamber 4 and ensure that the cooling temperature of each part in the cooling chamber 4 by the inner condenser tube 812 is as the same as possible. The setting of the outer condenser tube 813 can lead out the condensate after heat exchange by the inner condenser tube 812, cool it down and then introduce it again to ensure the cooling quality. The hot stamping liquid led out by the hose 7 sprays out towards the center position of the turntable 811. The fan blade 123 directly above the inner condenser tube 812 can further accelerate the discharge of heat.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
