[0001] The invention relates to a metal stamping device, in particular to a metal stamping device capable of working continuously and applied in the stamping processing field. Background Art

[0002] When performing continuous stamping operations on metal sheets, it is necessary to pay attention to the cooling operation of the stamping die to avoid product burrs caused by increased gaps due to thermal expansion of the die, or even premature scrapping of the die. Therefore, the die cooling operation of the stamping device is of great significance.

[0003] The specification of Chinese invention patent CN116020948B discloses a matching cooling mechanism based on a stamping die. This device solves the current problem of being unable to intelligently stamp metal and ensure that the coolant that is repeatedly recycled during cooling can effectively and naturally cool down.

[0004] The specification of Chinese invention patent CN117358812B discloses an automatic continuous stamping and cooling device. The temperature of mercury will expand and contract with the changes in the stamping die, driving the first piston to drive the first adjusting gear to rotate, thereby realizing the regulation of the opening and closing degree of the water supply valve, and has the effect of regulating the flow of cooling water according to the changes in the stamping die temperature.

[0005] The mold cooling device of the existing stamping device usually uniformly cools the mold cavity, and the cooling degree inside the mold is consistent. However, in fact, during the actual stamping process of the mold, there is a local high temperature state. Therefore, it is necessary to perform local targeted and efficient cooling operations on the cooling inside the mold to further improve the cooling effect. Summary of the Invention

[0006] In view of the above-mentioned prior art, the technical problem to be solved by the present invention is to improve the problem that the local high temperature state in the mold needs targeted cooling during the continuous metal stamping operation.

[0007] To solve the above problems, the present invention provides a continuously working metal stamping device, comprising a stamping table, a stamping bracket mounted on the top of the stamping table via a guide column, a hydraulic cylinder mounted on the top of the stamping bracket, an output end of the hydraulic cylinder being detachably connected to a stamping movable die, a stamping fixed die fixedly mounted on the top of the stamping table, a fixed die body mounted inside the stamping fixed die, the fixed die body and the inner wall of the stamping fixed die forming a cooling chamber, a cooling main pipe being mounted through the interior of the cooling chamber, isolation fences of an internal arc-shaped channel being mounted at the four corners of the cooling chamber, and a sealing cover being detachably mounted on the top of the cooling chamber;

[0008] The four outer walls and bottom of the fixed mold body are all equipped with open-designed isolation pieces, and temperature sensors are installed inside the isolation pieces. A liquid exchange tube is installed through the surface of the isolation piece. Two waterproof frames are installed on the inner wall of the isolation piece, and a drive motor is installed inside each waterproof frame. The output ends of the two drive motors are connected to the first and second rollers respectively. A storage frame with built-in ammonium chloride particles and corrosion inhibitor is installed inside the isolation piece, and a cooling branch made of a hose is installed inside each isolation piece.

[0009] A display assembly for displaying the position of each isolating member in the cooling chamber is arranged on one side of the stamping table, and a displacement sensor is installed inside each isolating member.

[0010] In the above-mentioned continuously working metal stamping device, the interior of the isolation part is integrated with an ammonium chloride particle storage frame and a sodium molybdate corrosion inhibitor chamber. The quantitative release of the medium and the waste liquid recovery are realized through the gear parts and gear condition linkage mechanism of the discharge pipe, thereby improving the local temperature control effect and equipment life.

[0011] As a further improvement of the present application, the surfaces of the No. 1 roller and the No. 2 roller are provided with anti-slip teeth, and the five inner walls of the stamping fixed mold and the five outer walls of the fixed mold body are provided with anti-slip stripes corresponding to the anti-slip teeth.

[0012] As a further improvement of the present application, a liquid exchange tube is installed through the surface of each isolation member, and an electromagnetic valve is installed on the surface of the liquid exchange tube. The open side surface of the isolation member is squeezed and contacted with the outer surface of the fixed mold body, and the isolation member is made of heat-insulating material.

[0013] As a further improvement of the present application, a discharge pipe is installed at the bottom of the storage frame, and a discharge baffle and a receiving plate are installed on the inner wall of the discharge pipe, which are arranged up and down, and the receiving plate is slidably connected to the inside of the discharge pipe. A discharge valve is installed inside the discharge baffle, and the bottom of the receiving plate is fixedly connected with symmetrically arranged gear conditions. The tail end of the discharge pipe is trumpet-shaped, and a gear part meshing with the gear condition is installed inside the discharge pipe, and the gear part is located near the tail end of the discharge pipe.

[0014] As a further improvement of the present application, a waterproof box is fixed to the inner wall of the tail end of the discharge pipe through a support rod, and a double-headed motor is installed inside the waterproof box. The two output ends of the double-headed motor are respectively connected to shafts extending to the outside of the waterproof box, and the two shafts are fixedly connected to the two gear parts.

[0015] As a further improvement of the present application, a one-way tube with an L-shaped cross-section is installed inside the discharge baffle, and the tail end of the one-way tube extends to the outside of the discharge pipe. The diameters of the receiving plate and the discharge baffle are the same as the inner diameter of the upper part of the discharge pipe.

[0016] As a further improvement of the present application, it also includes multiple infrared thermal imagers for monitoring the temperature conditions of the five outer surfaces of the fixed mold body and displaying the temperature conditions inside the fixed mold body through a display component.

[0017] As another improvement of the present application, a ball and a sealing ring located outside the ball are installed on the surface of the isolating member close to the fixed mold body. The sealing ring is slidably installed on the surface of the isolating member, and the surface of the sealing ring facing away from the fixed mold body is coated with a magnetic layer. The inner wall of the isolating member is provided with a circular groove corresponding to the sealing ring, and the inner wall of the circular groove is installed with an electromagnetic frame, and the electromagnetic frame is connected to the surface of the sealing ring through an elastic strip.

[0018] As another improvement supplement of the present application, when the electromagnetic frame is not started, there is a gap between the sealing ring and the surface of the fixed mold body, and the ball abuts against the surface of the fixed mold body.

[0019] To summarize, during continuous stamping, the infrared thermal imager monitors the temperature of the fixed mold body in real time to determine whether local enhanced cooling is required. If necessary, the isolator moves to the area to be locally enhanced cooled, and the ammonium chloride particles and corrosion inhibitor are quantitatively released through the discharge pipe. The heat absorption property of ammonium chloride particles when dissolved is utilized to enhance heat absorption on the basis of the coolant in the isolator, and the corrosion inhibitor is used to improve the anti-corrosion effect. In addition, a ball-electromagnetic sealing ring composite structure is adopted. Under normal circumstances, the ball contact reduces friction. After the electromagnetic frame is started, the sealing ring moves outward to enhance the sealing. The problems of local enhanced cooling, corrosion control and wear protection are solved through the collaborative use of mechanical intelligence. It is especially suitable for high-precision stamping scenarios, which improves the local temperature control effect and equipment life. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0035] The first implementation method:

[0036] Figures 1-4 A continuously working metal stamping device is shown, comprising a stamping table 1. A stamping bracket 100 is mounted on the top of the stamping table 1 via a guide column 2. A hydraulic cylinder is mounted on the top of the stamping bracket 100. The output end of the hydraulic cylinder is detachably connected to a stamping movable die 3. A stamping fixed die 4 is fixedly mounted on the top of the stamping table 1. A fixed die body is mounted inside the stamping fixed die 4. The fixed die body and the inner wall of the stamping fixed die 4 form a cooling chamber. A cooling main pipe 5 is installed through the interior of the cooling chamber. Isolation fences 7 for internal arc-shaped channels are mounted at the four corners of the cooling chamber. A sealing cover is detachably mounted on the top of the cooling chamber.

[0037] The four outer walls and the bottom of the fixed mold body are all provided with open-designed isolation members 8, and temperature sensors are installed inside the isolation members 8. A liquid exchange tube 81 is installed through the surface of the isolation member 8. Two waterproof frames 12 are installed on the inner wall of the isolation member 8, and a drive motor is installed inside each waterproof frame 12. The output ends of the two drive motors are respectively connected to the first roller 10 and the second roller 11. A storage frame 9 with built-in ammonium chloride particles and corrosion inhibitor is installed inside the isolation member 8, and a cooling branch pipe 6 made of a hose is installed inside each isolation member 8.

[0038] A display assembly for displaying the position of each isolating member 8 in the cooling chamber is arranged on one side of the stamping table 1 , and a displacement sensor is installed inside each isolating member 8 .

[0039] The surfaces of the first roller 10 and the second roller 11 are both provided with anti-skid teeth, and the five inner walls of the stamping fixed die 4 and the five outer walls of the fixed die body are both provided with anti-skid stripes corresponding to the anti-skid teeth.

[0040] A liquid exchange tube 81 is installed through the surface of each isolation member 8, and a solenoid valve is installed on the surface of the liquid exchange tube 81. The open side surface of the isolation member 8 is squeezed and connected to the outer surface of the fixed mold body, and the isolation member 8 is made of heat insulating material.

[0041] It also includes multiple infrared thermal imagers (not shown in the figure, which is existing technology and will not be described in detail) for monitoring the temperature of the five outer surfaces of the fixed mold body and displaying the temperature inside the fixed mold body through a display component.

[0042] Specifically, during the stamping operation, the hydraulically assisted stamping movable die 3 is used for stamping processing, so as to cooperate with the stamping fixed die 4 to achieve a stamping effect. During this process, the cooling main pipe 5 is used to inject coolant (water or other transparent liquids with good infrared transmittance, and an infrared transmission window is provided on the side wall of the stamping fixed die 4 to facilitate the infrared thermal imager to monitor the temperature of the surface of the fixed die body) into the cooling cavity to provide cooling operation for the fixed die body. When there is no need for targeted local enhanced cooling treatment, the liquid exchange pipe 81 can be opened to make the interior of the isolation member 8 in a state of communication with the interior of the cooling cavity. Due to the existence of the arc-shaped channel, the liquid in the entire cooling cavity is in a state of flow and communication. Since the overall cooling effect in the cooling cavity is consistent, the coolant injected into the cooling cavity through the cooling main pipe 5 can provide consistent cooling service to the fixed die body.

[0043] In addition, the cooling branch pipe 6 and the cooling main pipe 5 use piezoelectric ceramic valves to dynamically adjust the coolant flow rate according to the feedback of the temperature sensor.

[0044] When it is necessary to provide localized targeted enhanced cooling service to the fixed mold body, first close the solenoid valve on the surface of the liquid exchange tube 81, use the infrared thermal imager to locate the area on the surface of the fixed mold body that needs local enhanced cooling (hereinafter referred to as the marked area), then start the isolation piece 8 on the side surface, and use the anti-skid tooth pattern on the surface of the No. 1 roller 10 and the No. 2 roller 11 and the anti-skid tooth pattern on the inner wall of the stamping fixed mold 4 to move to the marked area (such as Figure 5-Figure 6 As shown, Figure 6 In the embodiment, the position of the isolator 8 is the local enhanced cooling area), and then the storage frame 9 is opened to release the ammonium chloride particles inside, and the heat absorption property of the ammonium chloride particles during dissolution is utilized (in this process, the isolator 8 maintains extrusion contact with the outer surface of the fixed mold body, because the ammonium chloride solution formed by the dissolution is basically inside the isolator 8, even if there is a small amount of overflow, there is no adverse effect on the enhanced cooling layout of this application). On the basis of the preliminary cooling of the coolant inside the isolator 8, enhanced cooling is carried out, and the effect of enhanced cooling can be achieved by controlling the amount of ammonium chloride released.

[0045] Figure 7-Figure 8 It is shown that a discharge pipe 13 is installed at the bottom of the storage frame 9, and a discharge baffle 14 and a receiving plate 15 are installed on the inner wall of the discharge pipe 13, which are arranged up and down, and the receiving plate 15 is slidably connected to the inside of the discharge pipe 13. A discharge valve is installed inside the discharge baffle 14, and a symmetrically arranged gear condition 18 is fixedly connected to the bottom of the receiving plate 15. The tail end of the discharge pipe 13 is trumpet-shaped, and a gear part 19 meshing with the gear condition 18 is installed inside the discharge pipe 13, and the gear part 19 is located near the tail end of the discharge pipe 13.

[0046] A waterproof box 17 is fixed to the inner wall of the tail end of the discharge pipe 13 through a support rod, and a double-headed motor is installed inside the waterproof box 17. The two output ends of the double-headed motor are respectively connected to shafts extending to the outside of the waterproof box 17, and the two shafts are fixedly connected to two gear parts 19.

[0047] A one-way tube 16 with an L-shaped cross-section is installed inside the discharge baffle 14, and the tail end of the one-way tube 16 extends to the outside of the discharge pipe 13. The diameters of the receiving plate 15 and the discharge baffle 14 are the same as the inner diameter of the upper part of the discharge pipe 13.

[0048] Specifically, when releasing ammonium chloride, the control valve is first used to release a certain amount of ammonium chloride particles to the surface of the receiving plate 15. At this time, the receiving plate 15 is located above the trumpet portion of the discharge pipe 13, and the one-way pipe 16 is a pipe body that only provides drainage. Therefore, there is no liquid between the receiving plate 15 and the discharge baffle 14. At this time, the ammonium chloride is not dissolved. Then the control valve is closed, and the double-headed motor drives the gear condition 18 to descend until the receiving plate 15 falls to the trumpet portion area. Due to the diameter difference between the receiving plate 15 and the trumpet portion, a gap is formed, which will cause the liquid inside the isolation member 8 to pass through the gap to contact the ammonium chloride particles on the surface of the receiving plate 15 with the liquid and dissolve (such as Figure 9 shown).

[0049] In order to enhance the dissolving effect, a double-headed motor can be used to drive the gear condition 18 to move up and down a small amount during this process, thereby driving the receiving plate 15 to move up and down on the horn part to enhance the dissolving effect.

[0050] After the enhanced cooling is completed, the double-headed motor is started to drive the gear condition 18 to move upward. As the receiving plate 15 moves upward, the liquid above the receiving plate 15 can be squeezed out. Since the discharge baffle 14 is fixed, the liquid above the receiving plate 15 is discharged from the inside of the discharge pipe 13 through the one-way pipe 16 (as shown in FIG. Figure 10 As shown), and during this process, the discharge pipe 13 is in a closed state, which can prevent the liquid above the receiving plate 15 from being squeezed and rising and flowing back into the interior of the storage frame 9, thereby achieving sustainable use of ammonium chloride particles.

[0051] When local enhanced cooling treatment is required in the next round, the cooling mixed solution (that is, the dissolved ammonium chloride solution) in the isolation member 8 is extracted and recovered using an external suction pump and cooling branch pipe 6 (it can be cooled to crystallize the ammonium chloride in the solution, which is a prior art and will not be described in detail), and new coolant is re-injected into the isolation member 8 to provide support for subsequent dissolution and preliminary cooling.

[0052] After the ammonium chloride particles are used up, the sealing cover is removed, the isolator 8 is taken out of the cooling chamber, and the storage frame 9 (which is provided with a waterproof feed port, which is prior art and will not be described in detail) is refilled.

[0053] In addition, since ammonium chloride is corrosive after dissolution, the relevant structures in this application (including the fixed mold body, the isolation member 8 and the waterproof frame 12, etc.) are all treated with anti-corrosion treatment (for example, coating with polytetrafluoroethylene coating, or other methods can also be used) to ensure the service life of the relevant structures in this application.

[0054] In addition, in order to prevent the corrosiveness of the ammonium chloride solution, the storage frame 9 can be divided into two storage chambers, one for storing ammonium chloride particles and the other for storing sodium molybdate. A discharge pipe 13 is installed at the bottom of each storage chamber. After releasing a certain amount of ammonium chloride particles, a certain amount (the discharge amount is controlled by controlling the opening time of the valve) of sodium molybdate is released. After sodium molybdate is added to the ammonium chloride solution as a corrosion inhibitor, corrosion is inhibited by forming a passivation film (because sodium molybdate may aggravate the corrosion of aluminum / copper parts, the relevant manufacturing materials in this application need to avoid aluminum / copper).

[0055] In the above process, the temperature of the fixed mold body can be detected by using an infrared thermal imager to preliminarily determine the parts that need local enhanced cooling, and according to the temperature state of the area, the cooling demand is determined, and the corresponding isolation member 8 is selected and moved to the area to release the corresponding amount of ammonium chloride particles, so that the temperature of the area after cooling is the same as the cooling effect of a single coolant passing through the adjacent area.

[0056] Second implementation method:

[0057] Figure 11-12 It is shown that a ball and a sealing ring 21 located outside the ball are installed on the surface of the isolation member 8 close to the fixed mold body. The sealing ring 21 is slidably installed on the surface of the isolation member 8, and the surface of the sealing ring 21 facing away from the fixed mold body is coated with a magnetic layer. The inner wall of the isolation member 8 is provided with a meandering groove corresponding to the sealing ring 21, and the inner wall of the meandering groove is installed with an electromagnetic frame 20, and the electromagnetic frame 20 is connected to the surface of the sealing ring 21 through an elastic strip.

[0058] As another improvement supplement of the present application, when the electromagnetic frame 20 is not started, there is a gap between the sealing ring 21 and the surface of the fixed mold body, and the ball abuts against the surface of the fixed mold body.

[0059] Different from the first embodiment, this embodiment is mainly used to reduce the wear between the isolation member 8 and the surface of the fixed mold body during movement, and can enhance the sealing inside the isolation member 8 when performing corresponding local enhanced cooling operations.

[0060] Specifically, when moving, the sealing ring 21 has a gap with the surface of the fixed mold body under the action of the elastic strip, while the ball bearings maintain rolling contact with the surface of the fixed mold body, thereby reducing the wear of the isolation member 8 caused by sliding friction when moving (at this time, the interior of the isolation member 8 is a single coolant, so even if the presence of the ball bearings causes a gap between the isolation member 8 and the surface of the fixed mold body, it will not have any effect).

[0061] When performing local enhanced cooling, the electromagnetic frame 20 is started to repel the magnetic layer, so that the sealing ring 21 can move outward and supplement the gap between the surface of the isolation member 8 and the surface of the fixed mold body to prevent the internal enhanced cooling liquid from overflowing, thereby ensuring the effect of local enhanced cooling.

[0062] In summary, during continuous stamping, the infrared thermal imager monitors the temperature of the fixed mold body in real time to determine whether local enhanced cooling is required. If necessary, the isolation part 8 is moved to the area to be locally enhanced cooled, and the ammonium chloride particles and corrosion inhibitor are quantitatively released through the discharge pipe 13. The heat absorption property of the ammonium chloride particles when dissolved is utilized to enhance heat absorption on the basis of the coolant in the isolation part 8, and the corrosion inhibitor is utilized to improve the anti-corrosion effect. In addition, a ball-electromagnetic sealing ring 21 composite structure is adopted. Under normal circumstances, the ball contact reduces friction. After the electromagnetic frame 20 is started, the sealing ring 21 moves outward to enhance the sealing. The problems of local enhanced cooling, corrosion control and wear protection are solved through the collaborative use of mechanical intelligence. It is especially suitable for high-precision stamping scenarios, and improves the local temperature control effect and equipment life.

[0063] In view of current actual needs, the protection scope of the above-mentioned implementation mode adopted in this application is not limited to this. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the protection scope of the present invention.
