Description

Technical Field

[0001] This invention relates to the field of corrugated plate forming and processing technology, specifically to a corrugated plate forming device and process for a constant temperature equipment condenser. Background Technology

[0002] A metal sheet processing stamping device, disclosed in the prior art with the publication number "CN112893609A", includes a stamping mechanism and a feeding mechanism. The stamping mechanism includes a stamping platform, a support base, a hydraulic cylinder, a pre-mounting plate, an upper stamping die, and a lower stamping die. The support base is L-shaped and mounted on the stamping platform, and the hydraulic cylinder is mounted on the top of the support base. The output shaft of the hydraulic cylinder passes through the support base and is connected to the pre-mounting plate. The upper stamping die is mounted on the pre-mounting plate. This metal sheet processing stamping device clamps the metal sheet through a clamping mechanism on the feeding mechanism. With the cooperation of a linear module and an electric slide, the metal sheet moves on the lower stamping die. After multiple stampings by the stamping mechanism, a mesh-like metal sheet is formed. This device can process large metal sheets. By using the feeding mechanism to drive the metal sheet to move reasonably and cooperating with the stamping mechanism to stamp it, it saves manpower and is highly efficient and fast.

[0003] The aforementioned stamping device can perform water ripple structure forming on sheet metal by improving the shape of the upper and lower stamping dies. However, the aforementioned metal sheet stamping device still has obvious defects in use: the device requires a feeding mechanism to clamp and fix the sheet metal to be processed, and the sheet metal is taken out by the feeding mechanism after stamping. There is a certain time gap in the process of transferring and assembling the next sheet metal to be processed, which affects the processing efficiency. At the same time, in the prior art, the sheet metal needs to be manually separated from the die after stamping, which also affects the production efficiency. Summary of the Invention

[0004] The purpose of this invention is to provide a device and process for forming a corrugated plate for a condenser in a constant temperature equipment, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A device for forming a corrugated plate condenser in a constant temperature equipment includes a worktable. An upper mold platform is lifted and installed above the worktable, and an upper mating mold is fixedly installed at the bottom of the upper mold platform. The upper mating mold and a lower mating mold are movably mated. The lower mating mold is lifted and installed in a mold lifting groove in the middle of the worktable. Driven by a lifting mechanism, the upper and lower mating molds move closer together to stamp the workpiece on the worktable. Roller lifting grooves are provided on both sides of the worktable in the feeding and discharging directions. Conveyor rollers are lifted and installed in the roller lifting grooves. The lifting direction of the conveyor rollers on both sides is opposite to the lifting direction of the lower mating mold. The conveyor rollers on both sides are used to feed the workpiece onto the worktable. After the workpiece is stamped, the lower mating mold descends to detach from the workpiece, while the conveyor rollers on both sides rise to lift the finished workpiece and allow it to leave the worktable as the conveyor rollers rotate.

[0007] The upper and lower mating molds are respectively provided with recessed parts and protrusions. The recessed or protruding parts of the upper and lower molds fit together as they approach each other. The protrusions or recesses of the upper and lower mating molds are provided with oil supply holes, and lubricating oil is pumped into the oil supply holes as the upper and lower molds approach each other.

[0008] Preferably, a pressure plate is also installed at the bottom of the upper mold table in a lifting and movable manner. The pressure plate has a stamping groove in the middle for the upper mold to pass through. The pressure plate is connected to the upper mold table by a compression spring. A lifting slide rod is also fixedly connected to the pressure plate on the inner side of the compression spring. The upper end of the lifting slide rod is slidably disposed in the slide rod groove opened in the upper mold table. The pressure plate limits and fixes the workpiece by abutting against it.

[0009] Preferably, the upper and lower mating molds are each fixedly provided with an oil supply chamber on opposite sides. The upper and lower oil supply chambers are connected to the oil supply hole through oil supply pipes. The upper and lower oil supply pipes are movably inserted into the oil supply chambers. The upper and lower mating molds are connected to the pump cylinders provided in the oil supply chambers through pump connecting rods. During the lifting and lowering process, the upper and lower mating molds pump external gas into the oil supply chambers, thereby increasing the internal pressure. The increased pressure in the oil supply chambers forces the stored lubricating oil to flow out from the oil supply hole through the oil supply pipes.

[0010] Preferably, the upper and lower mating molds are respectively fixedly connected to lifting drive rods on opposite sides. The lifting drive rods move up and down under the drive of the lifting mechanism. The lifting drive rod of the lower mating mold is also fitted with an oil pump piston cylinder. The oil pump piston cylinder is connected to the lifting piston cylinder through a pipe. The lifting piston cylinder is fixedly connected to the worktable. During the descent of the lower mating mold's lifting drive rod, it drives the oil pump piston to descend. The descending oil pump piston pumps the piston oil in the oil pump piston cylinder into the lifting piston cylinder through the pipe. The piston oil in the lifting piston cylinder pushes the lifting rod upward, and vice versa. The lifting of the lifting rod drives the conveyor roller to move up and down synchronously.

[0011] Preferably, the conveying roller is movably mounted on the roller frame, the lifting rod is fixedly connected to the roller frame, the roller frame is also provided with a sliding rod hole, a sliding rod is slidably arranged in the sliding rod hole, and the two ends of the sliding rod are fixedly installed in the roller lifting groove opened in the worktable.

[0012] Preferably, the conveying roller includes a magnetic adsorption cylinder and a rubber sleeve covering it. The magnetic adsorption cylinder has an internal electromagnet powered by an external power source. When the electromagnet is energized, the magnetic adsorption cylinder generates magnetic force to adsorb and transfer the processed workpiece.

[0013] Preferably, the worktable is provided with mating roller grooves on both sides of the workpiece traveling in the direction of travel, and mating rollers that move up and down synchronously with the conveying rollers are provided in the mating roller grooves.

[0014] A molding process for a corrugated water condenser plate of a constant temperature equipment, using the aforementioned corrugated water condenser plate molding device, includes the following steps:

[0015] Step 1: The processing plate is fed onto the worktable by the conveying mechanism. Driven by the conveying rollers on both sides of the worktable, the processing plate reaches the designated position. As the lower mating mold rises, the conveying rollers on both sides descend into the roller lifting groove, so that the processing plate contacts the worktable plane.

[0016] Step 2: The lifting mechanism drives the upper and lower mating molds to move towards each other. During the movement, lubricating oil is pumped out from the oil supply holes of the upper and lower mating molds to lubricate the stamping position. Through the mating and stamping of the upper and lower mating molds, a water ripple textured structure is formed on the processed sheet metal.

[0017] Step 3: After stamping is completed, the upper and lower mating dies move apart under the drive of the lifting mechanism. At this time, the workpiece is separated from the upper and lower mating dies. As the lower mating die descends into the die lifting groove, the conveyor rollers on both sides protrude out of the roller lifting groove again, thereby lifting the finished workpiece. As the conveyor rollers rotate, the workpiece is moved out of the worktable.

[0018] Compared with the prior art, the beneficial effects of the present invention are:

[0019] This invention employs a lifting-type upper and lower mating mold to complete the stamping forming operation of the water ripple structure on the processed sheet metal. Before and after stamping, the upper and lower mating molds move synchronously towards or away from each other. This operation allows the upper and lower mating molds to quickly separate from the processed sheet metal after stamping. Simultaneously, with the lifting of the conveyor rollers, the processed workpiece can be quickly transferred out of the worktable, achieving synchronous connection between the processing and the workpiece entering and leaving the worktable. In addition, before stamping, lubricating oil is applied to the stamping position through the oil supply hole of the upper and lower mating molds, thereby reducing damage to the workpiece or mold during the stamping process and improving processing efficiency.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figure 1-5 The present invention provides a technical solution:

[0028] Example 1:

[0029] A device for forming a corrugated plate condenser in a constant temperature equipment includes a worktable 1. An upper mold platform 2 is lifted and installed above the worktable 1. An upper mating mold 3 is fixedly installed at the bottom of the upper mold platform 2. The upper mating mold 3 and the lower mating mold 4 are movably mated. The lower mating mold 4 is lifted and installed in a mold lifting groove 5 opened in the middle of the worktable 1. The upper mating mold 3 and the lower mating mold 4 move closer to each other under the drive of the lifting mechanism to stamp the processing plate 6 on the worktable 1. Roller lifting grooves 7 are opened on both sides of the front and rear of the worktable 1 in the material feeding and discharging direction. Conveyor rollers 8 are lifted and installed in the roller lifting grooves 7. The lifting and lowering direction of the conveyor rollers 8 on both sides is opposite to the lifting and lowering direction of the lower mating mold 4. The conveyor rollers 8 on both sides are used to feed the processing plate 6 onto the worktable 1. After the processing plate 6 is stamped, the lower mating mold 4 descends to separate it from the processing plate 6. At the same time, the conveyor rollers 8 on both sides rise to lift the processed processing plate 6 and leave the worktable 1 as the conveyor rollers 8 rotate.

[0030] The upper mold 3 and the lower mold 4 are respectively provided with a recess 9 and a protrusion 10. The upper and lower recesses 9 or protrusions 10 are in a concave-convex fit when they approach each other. The upper mold 3 and the lower mold 4 are provided with oil supply holes 11 at the protrusions 10 or recesses 9. The upper and lower oil supply holes 11 pump lubricating oil when the upper mold 3 and the lower mold 4 approach each other.

[0031] In this embodiment, the workbench 1 is used to place the workpiece 6. The upper mating mold 3 and the lower mating mold 4 move closer to each other under the drive of the lifting mechanism to stamp the workpiece 6 on the workbench 1. The mechanism that drives the upper mating mold 3 and the lower mating mold 4 to move up and down is not shown. It adopts the lifting mechanism commonly used in stamping mechanisms in the prior art. Unlike the setting method in the prior art where one mold is fixed and the other mold moves, the upper mating mold 3 and the lower mating mold 4 in this embodiment adopt a moving mode of moving towards or away from each other to complete the stamping operation. The lower mating mold 4 protrudes from the mold lifting groove 5 during the stamping process, and after the stamping is completed, the lower mating mold 4 is retracted into the mold lifting groove 5. This operation allows the lower mating mold 4 to quickly separate from the workpiece 6 under the obstruction of the workbench 1. At the same time, roller lifting grooves 7 are opened on both sides of the front and rear of the workbench 1 in the material feeding and discharging direction. The roller lifting grooves 7 are equipped with lifting conveyor rollers 8, and the lifting direction of the conveyor rollers 8 is opposite to the lifting direction of the lower mating mold 4. When the lower mating mold 4 moves upward to perform an impact operation... When the upper and lower molds 3 and 4 are pressed, the upper mold 3 descends into the roller lifting groove 7. Conversely, when the lower mold 4 is pressed and descends into the roller lifting groove 7, the upper mold 8 protrudes from the plane formed by the worktable 1, thus lifting the workpiece 6. This arrangement allows the conveying mechanism to detach from supporting the workpiece 6 during the pressing process. After pressing, the conveying mechanism can re-engage the workpiece 6 to complete its transfer operation. This process does not require the participation of a robotic arm. As the pressed workpiece 6 moves out of the worktable 1, a new workpiece 6 can enter simultaneously. This method effectively improves the transfer efficiency, thereby improving production efficiency. At the same time, since the upper mold 3 and lower mold 4 need to be coated with lubricating oil during the pressing process, especially in cold forging, the temperature will rise rapidly, and lubrication is necessary. If the workpiece is pressed directly without lubrication, in addition to affecting the surface finish, the mold life will be shortened and the accuracy will be reduced. This device applies lubricating oil simultaneously during the lifting and lowering movement, reducing the time for applying lubricating oil and further improving production efficiency.

[0032] Example 2:

[0033] A pressure plate 12 is also installed at the bottom of the upper mold table 2 in a lifting and movable manner. The middle of the pressure plate 12 has a stamping groove 13 through which the upper mating mold 3 passes. The pressure plate 12 and the upper mold table 2 are connected by a compression spring 14. The pressure plate 12 is also fixedly connected to the inner side of the compression spring 14 and a lifting slide rod 15. The upper end of the lifting slide rod 15 is slidably set in the slide rod groove opened in the upper mold table 2. The pressure plate 12 is limited and fixed by abutting against the processed plate 6. In this embodiment, the descent of the upper mold table 2 causes the pressure plate 12 to abut against the processed plate 6 first, thereby preventing the processed plate 6 from shifting during the stamping process and ensuring the processing accuracy. When the stamping is completed, during the ascent of the upper mold table 2, under the action of the compression spring 14, the pressure plate 12 maintains continuous abutment against the processed plate 6, thereby causing the processed plate 6 to separate from the upper mating mold 3.

[0034] Example 3:

[0035] Oil supply chambers 16 are fixedly installed on opposite sides of the upper mating mold 3 and the lower mating mold 4. The upper and lower oil supply chambers 16 are connected to the oil supply holes 11 through oil supply pipes 17. The upper and lower oil supply pipes 17 are movably inserted into the oil supply chambers 16. The upper mating mold 3 and the lower mating mold 4 are connected to the pump cylinders 19 installed in the oil supply chambers 16 through the pump connecting rod 18. During the lifting and lowering process, the upper mating mold 3 and the lower mating mold 4 pump external gas into the oil supply chambers 16, thereby increasing the internal pressure. The increased pressure in the oil supply chambers 16 forces the stored lubricating oil to flow out from the oil supply holes 11 through the oil supply pipes 17. During the lifting and lowering process, the upper mating mold 3 and the lower mating mold 4... The pumping connecting rod 18 extends and retracts within the pumping cylinder 19. By setting a one-way air intake valve on the piston of the pumping connecting rod 18, gas enters the oil supply tank 16 from the external environment in one direction during each extension and retraction stroke. This process is similar to the principle of an air pump, which is quite common in real life and will not be elaborated here. This one-way inflation operation increases the pressure inside the well-sealed oil supply tank 16. The increased pressure in the oil supply tank 16 forces the stored lubricating oil to flow out from the oil supply hole 11 through the channel opened inside the oil supply pipe 17. The lubricating oil is pumped out in this way, eliminating the need for a pumping motor or an oil pumping motor.

[0036] Example 4:

[0037] Lifting drive rods 20 are fixedly connected to the upper mold 3 and the lower mold 4 on opposite sides. The lifting drive rods 20 move up and down under the drive of the lifting mechanism. An oil pump piston cylinder 21 is also fitted outside the lifting drive rod 20 of the lower mold 4. The oil pump piston cylinder 21 is connected to the lifting piston cylinder 23 via a pipe 22. The lifting piston cylinder 23 is fixedly connected to the worktable 1. During the descent of the lower mold 4, the lifting drive rod 20 drives the oil pump piston 24 to descend. The descending oil pump piston 24 pumps the piston oil in the oil pump piston cylinder 21 into the lifting piston cylinder 23 through the pipe 22. The piston oil in the lifting piston cylinder 23 pushes the lifting rod 31 upwards. The lifting rod 31 moves upwards, and vice versa. The lifting rod 31 drives the conveyor roller 8 to move up and down synchronously. In this embodiment, when the lifting drive rod 20, which is fixedly connected to the lower mating mold 4, moves up and down, the oil pump piston 24 moves up and down synchronously with it because it is fixed on the lifting drive rod 20. During this process, the oil pump piston 24 moves up and down, which drives the hydraulic oil in the oil pump piston cylinder 21 to enter and exit the lifting piston cylinder 23. The increase or decrease of the hydraulic oil in the lifting piston cylinder 23 drives the lifting rod 31 to complete the lifting operation. In this way, the movement direction of the lifting rod 31 is opposite to that of the lower mating mold 4, thereby ensuring the normal operation of the stamping and transfer process.

[0038] Example 5:

[0039] The conveyor roller 8 is movably mounted on the roller frame 25. The lifting rod 31 is fixedly connected to the roller frame 25. The roller frame 25 also has a sliding rod hole 26, and a sliding rod 27 is slidably arranged in the sliding rod hole 26. The two ends of the sliding rod 27 are fixedly installed in the roller lifting groove 7 opened in the worktable 1. The conveyor roller 8 includes a magnetic adsorption cylinder 28 and a rubber sleeve 29 that covers it. The magnetic adsorption cylinder 28 has an electromagnet built in it. The electromagnet is powered by an external power supply. When the electromagnet is energized, the magnetic adsorption cylinder 28 generates a magnetic force to adsorb and transfer the processed plate 6. The embodiment discloses the specific installation method of the conveyor roller 8. The lifting rod 31 pushes the roller frame 25 to rise and fall, thereby driving the conveyor roller 8 to rise and fall. At the same time, the conveyor roller 8 includes a magnetic adsorption cylinder 28 and a rubber sleeve 29 that wraps around it. The electromagnet built into the magnetic adsorption cylinder 28 is used to generate magnetism when energized, thereby adsorbing the processed plate 6. The rotation of the conveyor roller 8 is used to transfer the plate 6. The conveyor roller 8 is driven by a rotary motor that is fixedly installed on the roller frame 25 and coaxially arranged, thereby successfully completing the transfer operation of the processed plate 6.

[0040] Example 6:

[0041] The workbench 1 is provided with mating roller grooves 30 on both sides of the processing plate 6 in the direction of travel. The mating roller grooves 30 are provided with mating rollers that rise and fall synchronously with the conveyor rollers 8. In this embodiment, in order to ensure that the processing plate 6 can be transferred smoothly, mating roller grooves 30 are provided on both sides of the processing plate 6 in the direction of travel. The mating rollers are provided in the mating roller grooves 30. The mating rollers do not require power drive and are also set in the mating roller grooves 30 by a lifting method. Furthermore, by fixing the lifting rod 31 to the mounting frame of the mating roller, the synchronous lifting and lowering of the mating rollers can be realized. Since the roller frame 25 of the conveyor roller 8 has been fully disclosed, the mounting structure of the mating rollers can be implemented with a structure similar to that of the roller frame 25, which will not be described in detail here.

[0042] A molding process for a corrugated water condenser plate of a constant temperature equipment, using the aforementioned corrugated water condenser plate molding device, includes the following steps:

[0043] Step 1: The processing plate 6 is fed into the worktable 1 by the conveying mechanism. Driven by the conveying rollers 8 on both sides of the worktable 1, the processing plate 6 reaches the designated position. As the lower mating mold 4 rises, the conveying rollers 8 on both sides descend into the roller lifting groove 7, so that the processing plate 6 contacts the plane of the worktable 1.

[0044] Step 2: The lifting mechanism drives the upper mating mold 3 and the lower mating mold 4 to move towards each other. During the movement towards each other, lubricating oil is pumped out from the oil supply holes 11 opened by the upper mating mold 3 and the lower mating mold 4, thereby lubricating the stamping position. Through the mating stamping of the upper mating mold 3 and the lower mating mold 4, a water ripple concave-convex structure is formed on the processed plate 6.

[0045] Step 3: After stamping is completed, the upper mating mold 3 and the lower mating mold 4 move apart under the drive of the lifting mechanism. At this time, the processed plate 6 separates from the upper mating mold 3 and the lower mating mold 4. As the lower mating mold 4 descends into the mold lifting groove 5, the conveying rollers 8 on both sides protrude out of the roller lifting groove 7 again, thereby lifting the processed plate 6 and moving the processed plate 6 out of the worktable 1 as the conveying rollers 8 rotate.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
