Description

Technical Field

[0001] This utility model relates to the field of stamping and forming equipment technology, specifically a continuous forming device for bending cooling plates in a cooler. Background Technology

[0002] The bent cooling plate is a core component of heat exchange equipment, typically made by stamping and bending aluminum or stainless steel plates. In the mass production of cooling plates, the unloading process after stamping is a critical step affecting both production efficiency and safety. In the prior art, such as the automatic collection mechanism for stamping protective frames for containers disclosed in CN216566387U, the bottom of the fixed mold is provided by multiple equally spaced lifting blocks mounted on the frame, corresponding vertically to the stamping mold. The mechanism includes conveyor rollers, a conveyor belt, a drive motor, and a collection trough. Two conveyor rollers are provided and fixed on both sides of the stamping equipment. The drive motor is connected to one of the conveyor rollers via a transmission belt. A conveyor belt is mounted on the two conveyor rollers within the gap between the lifting blocks. The collection trough is located on one side of the stamping equipment, corresponding to the conveyor belt. This mechanism uses the lifting blocks to lift the stamped cooled plate blank, and then uses the conveyor belt to transport the cooled plate blank to the collection trough. The overall structure is reasonable and reliable, and automatic conveying achieves automatic collection of excess material.

[0003] However, the aforementioned existing technologies still have the following shortcomings in practical applications: 1. The lifting mechanism and the conveying mechanism are two independent structures. After the lifting action is completed, it is necessary to wait for the conveyor belt to start before the material can be discharged. The lifting and discharging are two independent processes, and there is a long time interval between the processes, which reduces production efficiency. 2. The independently set lifting blocks and conveyor belt occupy a large amount of equipment space, making the overall structure complex and maintenance inconvenient; 3. When the lifting block lifts the cooling plate blank, it acts directly on the forming surface of the cooling plate blank, which can easily leave indentations on the surface of the cooling plate blank, affecting the appearance quality and dimensional accuracy of the product. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a continuous forming device for bending cooling plates in a cooler, which solves the technical problems of existing devices.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A continuous forming device for bending cooling plates in a cooler includes a stamping table with a liftable upper die frame above it. The stamping table has a communicating assembly slot and a drive slot. It also includes a pressing plate, an adjusting plate, and a drive structure. The pressing plate is divided into a centrally recessed forming section and two supporting sections on either side. The supporting sections have evenly distributed and symmetrically arranged clearance slots along the forming section. The supporting sections are detachably connected to the assembly slot. The adjusting plate has four wheel frames fixedly mounted on its upper wall and elastically connected to the bottom of the drive slot. A drive wheel and a transmission wheel are rotatably connected within each wheel frame. The drive wheel is located at the drive end of the wheel frame, and the transmission wheel is located below the drive wheel. The transmission wheel and the drive wheel are connected by a synchronous belt. The adjusting plate has a fixedly mounted drive structure for driving the transmission wheel to rotate.

[0006] The preferred drive structure includes a shaft connecting seat, a drive shaft, a drive motor, a bevel gear assembly, and a synchronous pulley. The drive shaft is rotatably connected to the shaft connecting seat and is fixedly mounted on the upper wall of the adjusting plate. The drive motor is fixedly mounted on the upper wall of the adjusting plate and is meshed with the drive shaft via the bevel gear assembly; the synchronous pulleys are fixedly mounted on both output ends of the drive shaft and are connected to the drive pulleys by a synchronous belt.

[0007] Preferably, the adjusting plate has a guide hole, the bottom wall of the driving groove is fixedly installed with a guide rod that slides and adapts to the guide hole, the upper wall of the guide rod is fixedly installed with a bottom wall support platform, the side wall of the driving groove is fixedly installed with a side wall support platform, and both the bottom wall support platform and the side wall support platform abut against the forming part.

[0008] Preferably, a structural reinforcing rib is fixedly installed between the side wall support platform and the side wall of the drive groove.

[0009] Preferably, a plurality of evenly distributed spring positioning rods are fixedly installed on the lower wall of the adjusting plate, and a return spring is fixedly installed between the spring positioning rods and the bottom wall of the drive groove.

[0010] Preferably, the width of the clearance groove is adapted to the width of the drive wheel, and when the wheel frame rises to the lower wall of the support, the drive wheel extends along the clearance groove.

[0011] Preferably, the surface of the drive wheel is provided with anti-slip texture.

[0012] This utility model provides a continuous forming device for bending cooling plates in a cooler, which has the following advantages: 1. This utility model features a liftable wheel frame on an adjusting plate, with a drive wheel rotatably connected within the wheel frame. During the stamping process, the wheel frame descends with the adjusting plate, and the drive wheel retracts into the clearance slot. After stamping, the adjusting plate is reset by a return spring, and the drive wheel extends from the clearance slot, lifting the formed cooling plate blank off the surface of the pressing template. Subsequently, the drive motor starts, and the drive wheel rotates to directly transport the cooling plate blank forward to the next conveyor belt. The lifting and conveying actions are integrated into the same mechanism. After stamping, the drive wheel performs both lifting and conveying functions, eliminating the need for a separate lifting block. Material discharge does not require waiting for the conveyor belt to start, resulting in smooth process connections and effectively improving the continuous cycle time and production efficiency of the stamping operation.

[0013] 2. By setting up a bottom support platform and a side support platform, this utility model abuts against the lower wall of the forming part of the pressing template during stamping, and jointly bears the stamping pressure, thus avoiding the stamping load from acting directly on the adjusting plate and the return spring. The side support platform is provided with structural reinforcing ribs between itself and the side wall of the drive groove, which further improves the support rigidity, ensures good overall stability of the device during stamping, prevents deformation during long-term use, and extends the service life of the equipment.

[0014] 3. This utility model uses a drive wheel as a lifting element. After stamping, the drive wheel extends out of the clearance groove along with the upper mold frame and pushes the cooling plate blank away from the surface of the pressure plate in a rolling contact manner. This avoids the indentation damage caused by the traditional push rod directly pressing the surface of the cooling plate blank, and ensures the appearance quality and dimensional accuracy of the product. The drive wheel surface is provided with anti-slip texture to increase the friction between it and the cooling plate blank during the conveying process, prevent slippage during conveying, and ensure smooth and reliable material discharge.

[0015] 4. This utility model utilizes the energy stored in the return spring compressed by the stamping pressure. After stamping is completed, it achieves lifting through elastic automatic reset. It does not rely on an electrical system and automatically follows the stamping action, thereby improving stamping efficiency. Attached Figure Description

[0018] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0019] like Figure 1-5 As shown, the present invention discloses a continuous forming device for bending cooling plates of a cooler, including a stamping table 1, an upper mold frame 2 that can be raised and lowered is provided above the stamping table 1, the upper mold frame 2 is connected to the slider of the stamping machine, and is driven by the stamping machine to move up and down to complete the stamping action; the upper wall of the stamping table 1 is provided with a connecting assembly groove 3 and a drive groove 4, the assembly groove 3 is located in the middle and is used to fix the pressing template and limit the sheet metal parts, and the drive groove 4 is located below the assembly groove 3; The pressing template is divided into a centrally recessed forming part 5 and two horizontally oriented support parts 6. The shape of the forming part 5 is adapted to the bending shape of the cooling plate. Four evenly distributed clearance grooves 7 are provided on the two support parts 6, and the four clearance grooves 7 are symmetrically distributed along the forming part 5. The support parts 6 of the pressing template are detachably connected to the assembly groove 3 by positioning pins and bolts. The positioning pins ensure the installation accuracy of the pressing template, and the bolts provide sufficient clamping force to ensure that the pressing template will not be displaced during the stamping process.

[0020] A rectangular adjusting plate 8 is slidably connected inside the drive groove 4. Four wheel frames 9 are fixedly installed on the upper wall of the adjusting plate 8. The positions of the four wheel frames 9 correspond one-to-one with the positions of the four clearance grooves 7. A drive wheel 10 is rotatably connected to the upper part of each wheel frame 9, and a transmission wheel 11 is rotatably connected to the lower part. The transmission wheel 11 and the drive wheel 10 are connected by a synchronous belt. The surface of the drive wheel 10 is provided with anti-slip texture to increase the friction between it and the cooling plate blank and prevent slippage during transportation.

[0021] A drive structure is fixedly installed in the middle of the upper wall of the adjusting plate 8 to simultaneously drive four drive wheels 10 to rotate. The drive structure includes two shaft connecting seats 12, a transmission shaft 13, a drive motor 14, a set of bevel gear assemblies 15, and two synchronous pulleys 16. The two shaft connecting seats 12 are symmetrically fixedly installed in the upper wall of the adjusting plate 8, and the transmission shaft 13 is rotatably connected between the two shaft connecting seats 12. The drive motor 14 is fixedly installed in the upper wall of the adjusting plate 8, located on one side of the transmission shaft 13, and its output end is meshed with the middle of the transmission shaft 13 through the bevel gear assembly 15. A synchronous pulley 16 is fixedly installed at each end of the transmission shaft 13, and each synchronous pulley 16 drives two transmission wheels 11 on the same side to rotate simultaneously through a synchronous belt.

[0022] Multiple guide holes 17 can be opened on the adjusting plate 8. The bottom wall of the driving groove 4 is fixedly installed with the same number of guide rods 18. The guide rods 18 pass through the guide holes 17 and slide with the adjusting plate 8. The multiple guide rods 18 are symmetrically distributed at the four corners and the middle of the adjusting plate 8 to ensure that the adjusting plate 8 always remains horizontal and does not tilt. The upper end of the guide rod 18 is fixedly installed with a bottom wall support platform 19. The two side walls of the driving groove 4 are fixedly installed with side wall support platforms 20. The upper surfaces of the bottom wall support platform 19 and the side wall support platform 20 abut against the lower wall of the pressing template forming part 5 and jointly bear the stamping pressure. The side wall support platform 20 and the side wall of the driving groove 4 are welded with structural reinforcing ribs 21 to further improve the support rigidity.

[0023] A number of spring positioning rods 22 are fixedly installed on the lower wall of the adjusting plate 8. The number of spring positioning rods 22 is the same as the number of guide rods 18, and they are staggered with the guide rods 18. Each spring positioning rod 22 is fitted with a reset spring 23. The lower end of the reset spring 23 is fixedly connected to the bottom wall of the drive groove 4, and the upper end is fixedly connected to the lower wall of the adjusting plate 8. Specifically: The initial return spring 23 is in a naturally extended state, and the upper surface of the drive wheel 10 is slightly higher than the upper surface of the pressure plate support 6. The cooling plate blank to be stamped is placed on the drive wheel 10, and is initially limited by the side wall of the assembly groove 3 and the stamping table 1, so that the center of the cooling plate blank is aligned with the center of the forming part 5.

[0024] During stamping, the upper die holder 2 moves downward under the drive of the stamping press. After contacting the cooled blank, it continues to press down, pressing the cooled blank into the forming part 5 of the pressing die to complete the bending and forming process. During this process, the cooled blank pushes the drive wheel 10 and wheel frame 9 downward, causing the adjusting plate 8 to move downward along the guide rod 18, and the return spring 23 is compressed to store energy. When the adjusting plate 8 descends to the lowest position, the drive wheel 10 is fully retracted into the clearance groove 7, and the lower wall of the forming part 5 of the pressing die is supported by the bottom wall support platform 19 and the side wall support platform 20, which together bear the huge stamping pressure.

[0025] After stamping, the upper die holder 2 moves upward and disengages from the pressure die. At this time, the return spring 23 releases its stored energy, pushing the adjusting plate 8 and the wheel frame 9 upward. The drive wheel 10 extends from the clearance groove 7, pushing the formed cooling plate blank away from the surface of the pressure die, reducing the friction during the conveying of the cooling plate blank. When the wheel frame 9 rises to its highest position, its upper end rests against the lower wall of the support part 6, achieving a limit.

[0026] At this time, the drive motor 14 starts, driving the transmission shaft 13 and the synchronous pulley 16 to rotate through the bevel gear assembly 15. The synchronous pulley 16 drives the transmission pulley 11 and the drive wheel 10 to rotate through the synchronous belt. The four drive wheels 10 rotate synchronously, conveying the cooled plate blank forward to the next conveyor belt. The linear speed of the drive wheel 10 is the same as the speed of the next conveyor belt. When one end of the cooled plate blank contacts the conveyor belt, the other end gradually disengages from the drive wheel 10 and is eventually completely conveyed to the next process by the conveyor belt.

[0027] After the cooled blank is completely separated from the drive wheel 10, the drive motor 14 stops rotating, the device returns to its initial state, and is ready for the next stamping.

[0028] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
