Description

Technical Field

[0001] The present invention relates to the technical field of stamping equipment, and particularly to a stamping equipment for an aluminum profile frame of an automobile radiator. Background Art

[0002] As an important part of an automobile, the automobile radiator determines the heat dissipation performance of the automobile and also affects the power of the automobile. Most of the traditional automobile radiator frames are made of steel. Although they have sufficient strength and stability, their weight is relatively heavy, which affects the lightweight goal of the automobile. Therefore, radiator frames made of aluminum alloy are gradually applied to automobile production. Aluminum alloy has a high specific strength and specific stiffness, and at the same time its weight is relatively light, which can meet the requirements of automobile lightweight. Due to the good ductility of aluminum, stamping equipment is often used in industry to produce and process aluminum profile frames by stamping.

[0003] During the stamping process of the aluminum profile frame of an automobile radiator, due to the uneven surface and uneven thickness of the aluminum profile, the punching force is unevenly distributed, which may seriously cause local deformation or cracks in the frame, thus affecting the utilization efficiency of the equipment.

A puncher is installed on the top of the frame. The puncher provides the main power source for the stamping action. A pressure-sharing moving die is installed at the output end of the puncher. The pressure-sharing moving die divides the pressure and performs preliminary forming on the aluminum profile during the stamping process. A blanking fixed die is arranged below the pressure-sharing moving die. The outer edge surface of the blanking fixed die is connected to the inner wall of the top of the frame. The pressure-sharing moving die is used to stamp the aluminum profile raw material to form the aluminum profile frame of the automobile radiator.

The inner walls of the four corners of the lifting plate are adapted to slide on the outer surface of the guide rods.

[0007] Preferably, the pressure-dividing component includes a blank-holding frame plate which is used to fix the aluminum profile in a certain position before stamping, prevent its displacement during stamping, and ensure the stamping accuracy. The inner edge surface of the blank-holding frame plate is adapted to slide on the outer edge surface of the stamping head. A connecting plate is fixedly connected to the surface of adjacent blank-holding frame plates. A sliding groove is formed on the inner wall of the blank-holding frame plate.

A guide sleeve is slidably sleeved on the top of the outer edge surface of the sliding rod. The top of the guide sleeve is fixed to the bottom surface of the lifting plate. A compression spring is fixedly connected to the bottom surface of the guide sleeve. The compression spring is movably sleeved outside the sliding rod. The bottom surface of the compression spring is fixed to the top of the blank-holding frame plate. The compression spring plays a role in buffering and resetting, absorbs the impact force during stamping, and at the same time helps the related components return to the initial position after stamping is completed.

[0008] Preferably, the blanking fixed die includes a fixed template which provides a stable working plane for the stamping process. The outer edge surface of the fixed template is fixed to the inner wall of the top of the frame.

[0013] Preferably, the conveying frame includes an outer frame, which serves as an external protection structure. The inner surface of the outer frame is fixed to the top of the outer surface of the machine frame. A limiting and guiding groove is formed on the inner wall of the outer frame, which is used to limit and guide the aluminum profile during the feeding process to ensure that the aluminum profile accurately enters the stamping position. The limiting and guiding groove is flush with the material clamping groove. A roller is rotatably fitted on the inner wall of the limiting and guiding groove, and the roller reduces the friction during the conveying process, enabling the aluminum profile to smoothly move within the conveying frame.

The bottom surface of the sliding rod is fixedly connected to a connecting frame plate, and the middle of the bottom surface of the connecting frame plate is fixedly connected to a fitting pressing plate. Roller wheels are arranged on both sides of the fitting pressing plate, which assist in conveying the aluminum profile, reduce the conveying resistance, and improve the conveying efficiency. The ends of the roller wheels are rotatably fitted with the inner wall of the connecting frame plate.

[0015] The present invention provides a stamping device for an aluminum profile frame of an automobile radiator. It has the following beneficial effects:

[0016] First, in this stamping device for the aluminum profile frame of the automobile radiator, through the setting of the feeder, the aluminum profile raw material is flattened, and the aluminum profile raw material is limited in cooperation with the material clamping groove and the blocking device. Then, the punching press is used to drive the divided moving die to move, so that the divided moving die cooperates with the unloading fixed die for multi-stage stamping and restricts the stamping area to achieve stable stamping of the aluminum profile raw material. In addition, by setting the unloading fixed die, the stamping waste can be scraped off to prevent jamming in the device and affecting the subsequent stamping accuracy, thereby effectively improving the utilization efficiency of the stamping device.

[0017] Second, in this stamping device for the aluminum profile frame of the automobile radiator, through the setting of the limiting and guiding groove and the roller, the aluminum profile raw material is guided, and in cooperation with the contact of the fitting pressing plate and the roller wheels, the unevenness on the surface of the aluminum profile raw material is forced to be restored. Then, by using the contact between the fitting pressing plate and the roller wheels and the surface of the aluminum profile, the sliding rod slides in the sleeve and compresses the spring member to deform. With the resilience of the spring member, the pressure on the contact surface between the fitting pressing plate and the roller wheels and the aluminum profile is further enhanced to ensure the restoration effect of the unevenness on the surface of the aluminum profile, thereby improving the safety of subsequent stamping operations.

[0018] III. The aluminum profile frame stamping equipment for automobile radiators enables the aluminum profile raw materials restored by extrusion of the feeder to be stably guided below the pressure-dividing moving die through the setting of the material clamping groove. Moreover, the end of the aluminum profile is blocked by the setting of the sealing baffle to ensure the stability of the aluminum profile stamping process. In addition, the hydraulic device and the top plate cooperate to lower the lifting plate. Through the initial contact between the pressure frame plate and the surface of the aluminum profile, pre-fixation of the aluminum profile is carried out during stamping. Then, the pressure frame plate contacts the aluminum profile to squeeze the sliding rod, causing the sliding rod to slide in the guiding sleeve, and at the same time compressing the compression spring to deform. At this time, in cooperation with the sliding of the stamping head on the inner wall of the sliding groove, the stamping head stamps the aluminum profile, and the stable forming of the automobile radiator frame is realized in cooperation with the fixed template. During the stamping process, the stamping area is restricted, thereby improving the stamping quality of the aluminum profile.

[0019] IV. The aluminum profile frame stamping equipment for automobile radiators punches the stamping waste from the aluminum profile through the sliding of the stamping head in the fixed template and the supporting plate. And in cooperation with the continuous punching force of the stamping head on the waste, the waste moves downward through the inclined surface guide groove and the scraping arc block. When the stamping head resets, in cooperation with the contact friction force between the scraping arc block and the stamping head, the waste is scraped off from the stamping head. The setting of the scraping and blocking plate is used to prevent the waste from getting stuck in the equipment. In addition, due to the inclined surface setting of the guide and discharge inclined plate and in cooperation with the stamping vibration force during the stamping process, the stamping waste quickly slides on the guide and discharge inclined plate and is discharged to the outside, thereby further improving the use efficiency of the equipment.

Specific Embodiments

[0033] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not exhaustive or limited to the disclosed form. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described to better illustrate the principles and practical applications of the present invention, and to enable those of ordinary skill in the art to understand the present invention and thus design various embodiments with various modifications suitable for specific purposes.

[0034] The first embodiment is as Figures 1 to 10As shown in the figure, the present invention provides a technical solution: a stamping device for an aluminum profile frame of an automobile radiator, which includes a frame 1. A stamping press 2 is installed on the top of the frame 1. The output end of the stamping press 2 is installed with a pressure-dividing moving die 3. A blanking fixed die 4 is arranged below the pressure-dividing moving die 3. The outer edge surface of the blanking fixed die 4 is connected to the inner wall of the top of the frame 1. The pressure-dividing moving die 3 is used to stamp the aluminum profile raw material to form the aluminum profile frame of the automobile radiator. The blanking fixed die 4 is used to assist the pressure-dividing moving die 3 to achieve the stamping action and scrape off the stamping waste. A feeder 5 is installed on one side of the blanking fixed die 4. The feeder 5 is used to assist in conveying the aluminum profile raw material and flatten it. A baffle 6 is installed on the side of the blanking fixed die 4 away from the feeder 5. A material clamping groove 7 is opened on the inner wall of the top of the frame 1. The material clamping groove 7 is used to cooperate with the baffle 6 to limit the position of the aluminum profile raw material. Through the setting of the feeder 5, the aluminum profile raw material is flattened, and the aluminum profile raw material is limited in cooperation with the material clamping groove 7 and the baffle 6. Then, the stamping press 2 is used to drive the pressure-dividing moving die 3 to move, so that the pressure-dividing moving die 3 cooperates with the blanking fixed die 4 for multi-stage stamping and limits the stamping area to achieve stable stamping of the aluminum profile raw material. In addition, by using the setting of the blanking fixed die 4, the stamping waste can be scraped off to avoid jamming in the equipment and affecting the subsequent stamping accuracy, thereby effectively improving the utilization efficiency of the stamping equipment;

[0035] Among them, the pressure-dividing dynamic die 3 includes a lifting plate 31. The top of the lifting plate 31 is connected to the output end of the punching press 2. A punching head 33 is fixedly installed on the bottom surface of the lifting plate 31. There are several punching heads 33, which are equally spaced on the bottom surface of the lifting plate 31. A pressure-dividing member 32 is movably sleeved outside the punching head 33. The top of the pressure-dividing member 32 is connected to the bottom surface of the lifting plate 31. The punching press 2 includes a guide rod 23. The bottom surface of the guide rod 23 is fixed to the top of the machine frame 1. There are four guide rods 23, which are distributed at the four corners of the top of the machine frame 1. A top plate 22 is fixedly installed at the top of the guide rod 23. In the middle of the upper surface of the top plate 22, a hydraulic device 21 is fixedly installed. The output shaft of the hydraulic device 21 penetrates the top plate 22 and slides with the inner wall of the top plate 22. The end of the output shaft of the hydraulic device 21 is fixed to the top of the lifting plate 31. The inner walls at the four corners of the lifting plate 31 are adapted to slide with the outer surface of the guide rod 23. The pressure-dividing member 32 includes a blank-holding frame plate 321. The inner edge surface of the blank-holding frame plate 321 is adapted to slide with the outer edge surface of the punching head 33. A connecting plate 322 is fixedly connected to the surface of adjacent blank-holding frame plates 321. A sliding groove 326 is formed in the inner wall of the blank-holding frame plate 321. The outer edge surface of the punching head 33 slides with the inner wall of the sliding groove 326. At the four corners of the top of the blank-holding frame plate 321, sliding rods 324 are fixedly installed. A guide sleeve 323 is slidably sleeved at the top of the outer edge surface of the sliding rod 324. The top of the guide sleeve 323 is fixed to the bottom surface of the lifting plate 31. A compression spring 325 is fixedly connected to the bottom surface of the guide sleeve 323. The compression spring 325 is movably sleeved outside the sliding rod 324. The bottom surface of the compression spring 325 is fixed to the top of the blank-holding frame plate 321. Through the setting of the material clamping groove 7, the aluminum profile raw material restored by the feeder 5 is stably guided to the lower part of the pressure-dividing dynamic die 3. Moreover, by using the setting of the sealing baffle 62, the end of the aluminum profile is blocked to ensure the stability of the aluminum profile stamping process. In addition, by using the cooperation of the hydraulic device 21 and the top plate 22, the lifting plate 31 descends. Through the preliminary contact between the blank-holding frame plate 321 and the surface of the aluminum profile, the aluminum profile is pre-fixed during stamping. Then, by using the contact between the blank-holding frame plate 321 and the aluminum profile to squeeze the sliding rod 324, the sliding rod 324 slides in the guide sleeve 323, and at the same time, the compression spring 325 is compressed and deformed. At this time, in cooperation with the sliding of the punching head 33 on the inner wall of the sliding groove 326, the punching head 33 punches the aluminum profile, and in cooperation with the fixed template 41, the stable forming of the automotive radiator frame is realized. During the stamping process, the stamping area is restricted, thereby improving the stamping quality of the aluminum profile.

[0036] During operation, first, the aluminum profile raw material is conveyed to the stamping position by the feeder 5, and is preliminarily flattened during the feeding process to ensure the flatness of the raw material. Subsequently, the raw material is placed on the unloading fixed die 4, and under the combined action of the baffle 6 and the material clamping groove 7, the position of the raw material is accurately restricted to ensure the accuracy and stability during stamping. When the aluminum profile raw material is ready, the hydraulic device 21 is activated, and its output shaft drives the lifting plate 31 and the stamping head 33 and the pressure dividing member 32 installed on its bottom surface to descend. During the stamping process, the pressure frame plate 321 is movably sleeved outside the stamping head 33. Through the elastic force of the compression spring 325, the pressure frame plate 321 can evenly distribute the stamping force, avoiding stress concentration and raw material deformation during stamping. At the same time, the stamping head 33 directly contacts and stamps the aluminum profile raw material to form the required shape of the aluminum profile frame for the automotive radiator. When the stamping head 33 completes stamping, the unloading fixed die 4 is used to scrape off the stamping waste from the formed aluminum profile frame to achieve automatic separation of the waste. After stamping is completed, the hydraulic device 21 acts in the reverse direction, driving the lifting plate 31 and its attached components to rise and reset, preparing for the next stamping cycle. At the same time, the feeder 5 continues to feed, and the baffle 6 and the material clamping groove 7 reposition the new raw material to ensure the continuity and high efficiency of the entire stamping process.

[0037] Second Embodiment. On the basis of the first embodiment, please refer to Figures 3 to 7 As shown, the unloading fixed die 4 includes a fixed template 41. The outer edge surface of the fixed template 41 is fixed to the inner wall of the top of the frame 1. The bottom surface of the fixed template 41 is provided with an unloading scraper 42. The outer edge surface of the unloading scraper 42 is connected to the inner wall of the top of the frame 1. The middle part of the bottom surface of the unloading scraper 42 is provided with a waste guiding and discharging member 43. The bottom surface of the waste guiding and discharging member 43 is connected to the bottom surface of the inner wall of the frame 1;

[0038] The unloading scraper 42 includes a supporting plate 421, the top of which is fixed to the bottom surface of the fixed template 41, and the stamping waste is punched out from the aluminum profile by the sliding of the punch head 33 in the fixed template 41 and the supporting plate 421. A through groove 422 is provided on the inner wall of the supporting plate 421, and a scraper arc block 423 is fixedly installed on the inner wall of the through groove 422. The top of the scraper arc block 423 is fixed to the bottom surface of the fixed template 41, and an inclined guide groove 424 is provided on the outer arc surface of the scraper arc block 423. The bottom surface of the inclined guide groove 424 is fixedly connected with a scraper plugging plate 425, and one side surface of the scraper plugging plate 425 is fixed to the inner wall of the through groove 422, and the continuous punching pressure of the punch head 33 on the waste is cooperated, so that the waste passes through the inclined guide groove 424 and the scraper arc block 423 and is discharged to the aluminum profile. The scraper block 425 is provided to prevent the waste from being stuck in the equipment. In addition, the inclined surface of the guide plate 432 is used to set the stamping waste, and the stamping waste is quickly discharged to the outside by the inclined surface of the guide plate 432, thereby further improving the utilization efficiency of the equipment.

[0039] During operation, during the stamping process, the aluminum profile raw material is placed on the fixed template 41, and the stamping waste is punched off the aluminum profile by the sliding of the punch head 33 in the fixed template 41 and the supporting plate 421. The continuous stamping pressure of the punch head 33 on the waste is used to make the waste pass through the inclined guide groove 424 and the scraper arc block 423 and move downward. When the punch head 33 is reset, the scraper arc block 423 and the punch head 33 are used to scrape the waste off the punch head 33. The scraper blocking plate 425 is used to prevent the waste from getting stuck in the equipment. In addition, the inclined surface setting of the guide inclined plate 432 is used in combination with the stamping vibration force of the stamping process to make the stamping waste quickly slide on the guide inclined plate 432 and be discharged to the outside.

[0040] The third embodiment is based on the first and second embodiments. Figure 2 , Figure 3 , Figure 4 , Figure 11 , Figure 12 As shown, the blocking device 6 includes a cylinder 61, which is fixedly mounted on the top of the frame 1, and the end of the output shaft of the cylinder 61 is fixedly connected to a blocking plate 62, and a side surface of the blocking plate 62 slides with the side surface of the fixed template 41 away from the feeder 5;

[0041] The feeder 5 includes a conveying frame 51. One side surface of the conveying frame 51 is connected to the top outer surface of the frame 1 and is in contact with the side surface of the fixed template 41 away from the sealing baffle 62. A fixed top plate 52 is installed on the top of the conveying frame 51. A pressing member 53 is installed on the inner wall top of the fixed top plate 52. The pressing member 53 is used to assist in flattening the aluminum profile raw material. The conveying frame 51 includes an outer frame 511. The inner side surface of the outer frame 511 is fixed to the top outer surface of the frame 1. A limiting guiding groove 512 is formed on the inner wall of the outer frame 511. The limiting guiding groove 512 is flush with the material clamping groove 7. A roller 513 is rotatably fitted on the inner wall of the limiting guiding groove 512. The pressing member 53 includes a sleeve 531. The top of the sleeve 531 is fixed to the inner wall top of the fixed top plate 52. A sliding rod 532 is slidably fitted on the inner edge surface of the sleeve 531. The top of the sliding rod 532 is fixedly connected to a spring member 536. The top of the spring member 536 is fixed to the inner cavity top of the sleeve 531. The bottom surface of the sliding rod 532 is fixedly connected to a connecting frame plate 533. The middle of the bottom surface of the connecting frame plate 533 is fixedly connected to a fitting pressing plate 534. Rollers 535 are arranged on both sides of the fitting pressing plate 534. The ends of the rollers 535 are rotatably fitted with the inner wall of the connecting frame plate 533. Through the arrangement of the limiting guiding groove 512 and the roller 513, the aluminum profile raw material is guided, and in cooperation with the contact of the fitting pressing plate 534 and the rollers 535, the unevenness on the surface of the aluminum profile raw material is forced to be restored. Then, by using the contact of the fitting pressing plate 534 and the rollers 535 with the surface of the aluminum profile, the sliding rod 532 slides in the sleeve 531 and compresses the spring member 536 to deform. With the resilience of the spring member 536, the pressure on the contact surface between the fitting pressing plate 534 and the rollers 535 and the aluminum profile is further enhanced to ensure the restoration effect of the unevenness on the surface of the aluminum profile, thereby improving the safety of subsequent stamping operations.

[0042] During operation, the aluminum profile raw material is placed in the conveying frame 51 and is preliminarily guided and positioned through the limiting guiding groove 512 inside the outer frame 511. The setting of the roller 513 reduces the friction between the raw material and the outer frame 511, making the feeding process smoother. The raw material moves forward within the conveying frame 51 until it contacts the edge of the fixed template 41. At this time, the pressing member 53 starts to work. The spring member 536 inside the sleeve 531 drives the sliding rod 532 to descend, thereby driving the connecting frame plate 533 and the fitting pressing plate 534 to press the raw material flat, ensuring that the raw material is in a flat state before stamping. At the same time, the rotation of the roller 535 helps to reduce the friction between the pressing plate and the raw material and improves the flattening effect. When the raw material is sent to the stamping position of the fixed template 41 and flattened, the cylinder 61 drives the sealing baffle 62 to move forward until it closely adheres to the edge of the fixed template 41. The function of the sealing baffle 62 is to prevent the raw material from moving forward or popping out due to the force during the stamping process, ensuring the accuracy and safety of stamping. With the sealing baffle 62 in place, the puncher 2 starts to descend for stamping operations. After stamping is completed, the sealing baffle 62 returns to its original position under the drive of the cylinder 61 to prepare for the next feeding and stamping.

[0043] The working principle of the aluminum profile frame stamping equipment for automotive radiators will be specifically described below.

[0044] In use, first, the aluminum profile raw material is placed in the conveying frame 51 and is preliminarily guided and positioned through the limiting guide groove 512 inside the outer frame 511. The setting of the rollers 513 reduces the friction between the raw material and the outer frame 511, making the feeding process smoother. The raw material moves forward within the conveying frame 51 until it touches the edge of the fixed template 41. At this time, the pressing member 53 starts to work. The spring member 536 inside the sleeve 531 drives the sliding rod 532 to descend, and then drives the connecting frame plate 533 and the fitting pressing plate 534 to press the raw material flat, ensuring that the raw material is in a flat state before stamping. Subsequently, when the raw material is sent to the stamping position of the fixed template 41 and pressed flat, the cylinder 61 drives the sealing baffle 62 to move forward until it closely adheres to the edge of the fixed template 41 to precisely limit the position of the raw material. When the aluminum profile raw material is ready, the hydraulic device 21 is started, and the output shaft drives the lifting plate 31 and the stamping head 33 and the pressure dividing member 32 installed on its bottom surface to descend. During the stamping process, the pressing frame plate 321 is movably sleeved outside the stamping head 33. Through the elastic force of the compression spring 325, the pressing frame plate 321 can evenly distribute the stamping force, avoiding stress concentration and raw material deformation during stamping. At the same time, the stamping head 33 directly contacts and stamps the aluminum profile raw material to form the required shape of the aluminum profile frame for the automotive radiator. When the stamping head 33 finishes stamping, through the sliding of the stamping head 33 in the fixed template 41 and the supporting plate 421, the stamping waste is punched off from the aluminum profile. Using the continuous punching force of the stamping head 33 on the waste, the waste passes through the inclined surface guide groove 424 and the scraping arc block 423 and moves downward. When the stamping head 33 resets, with the cooperation of the contact friction force between the scraping arc block 423 and the stamping head 33, the waste is scraped off from the stamping head 33. The sticking scraping plug plate 425 is used to prevent the waste from getting stuck in the equipment. In addition, by using the inclined surface setting of the guide discharge inclined plate 432 and cooperating with the stamping vibration force during the stamping process, the stamping waste quickly slides down on the guide discharge inclined plate 432 and is discharged to the outside to realize the automatic separation of the waste. After stamping, the hydraulic device 21 acts in the reverse direction, driving the lifting plate 31 and its attached components to rise and reset, preparing for the next stamping cycle. At the same time, the feeder 5 continues to feed, and the baffle 6 and the material clamping groove 7 reposition the new raw material to ensure the continuity and high efficiency of the entire stamping process.
