Description

Technical Field

[0001] This invention relates to the field of photovoltaic frame processing technology, specifically to an aluminum profile stamping die and stamping method. Background Technology

[0002] Photovoltaic frames are used to fix photovoltaic panels and connect them to photovoltaic brackets. They are generally made of square-tube-shaped aluminum profiles with 45-degree bevels at both ends. During production, aluminum profiles of a predetermined length are first cut to form the photovoltaic frame, and then punched. Cutting is commonly done using a cutting machine, while punching is typically done using a stamping machine. For example, CN116214093A discloses a multi-station integrated processing equipment for photovoltaic frames, which uses a bevel cutting machine to bevel the square-tube aluminum profiles and then uses a punching mechanism to punch holes in the profiles. However, this method has some shortcomings. For example: 1. When using a cutting machine to cut square aluminum profiles, the cutting machine's blade rotates at high speed while feeding, which takes a certain amount of time to cut the aluminum profile. Compared with the punching method, the efficiency is relatively low. Therefore, it is necessary to improve the cutting method to increase the cutting efficiency. 2. Whether it is punching or punching, stamping technology is used. However, the photovoltaic frame is square tube in shape. During stamping, the stamping equipment can easily clamp the square tube on the outside, but there is no support inside the square tube. In addition, the hardness of aluminum profiles is relatively low. During stamping, the stamping surface of the square tube is easily dented, which affects the processing quality.

[0003] Based on the above, this invention proposes an aluminum profile stamping die and stamping method that improves efficiency, enhances processing quality, and automates stamping. Summary of the Invention

[0004] To address the problems mentioned in the background above, the present invention provides an aluminum profile stamping die and a stamping method.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by the present invention is as follows.

[0006] An aluminum profile stamping die includes a frame on which stamping components, a support mechanism, and auxiliary components are mounted. The support mechanism is configured to switch between a clearance state and a support state. Initially, the support mechanism is in the clearance state. The inner support component in the support mechanism is an integrated structure for feeding square aluminum profiles. During the stamping process, when the support mechanism switches to the support state, it is used to support the square aluminum profile to be stamped from both the inside and outside. The support mechanism includes a mold frame mounted on the machine frame, on which an outer support component and an inner support component are installed. The outer support component includes an outer mold area that is horizontally arranged and runs through the mold frame. Notches are opened through the upper and lower sides of the outer mold area. The upper notch is a stamping port and the lower notch is a blanking port. The internal support component includes a support column with one end open and the other end closed. The center line of the support column coincides with the center line of the outer mold area. The support column includes a central support block located in the outer mold area and a left support column and a right support column respectively set at both ends of the central support block. The left support column is connected to the mold frame. Both ends of the left support column are open. The support column is equipped with a clamping assembly. Initially, the clamping assembly applies internal clamping to the central support block, the left support column and the right support column at the same time.

[0007] Furthermore, the clamping assembly includes a connecting seat fitted inside the left support column. An outer sleeve is connected to the side of the connecting seat facing the middle support block. An inner sliding column is slidably installed inside the outer sleeve along the center line of the support column. An inlay groove is provided on the side of the outer sleeve, and a clamping plate is installed in the inlay groove. A bracket extends from the inner side of the clamping plate. The bracket and the outer sleeve form a sliding fit, and the sliding direction is perpendicular to the side of the outer sleeve where the inlay groove is provided. A protruding pin is provided on the bracket, and an inclined linkage hole is provided on the inner sliding column. The end of the protruding pin slides in the linkage hole. The distance between the linkage hole and the center line of the support column decreases along the direction from the left support column to the middle support block.

[0008] Furthermore, the outer sleeve and the connecting seat form a sliding fit along the center line of the support column. A spring three is provided between the outer sleeve and the connecting seat. One end of the inner sliding column extends into the space between the outer sleeve and the connecting seat, and a spring four is provided between that end of the inner sliding column and the outer sleeve. A hydraulic rod is provided inside the left support column to drive the connecting seat to move within the left support column.

[0009] Furthermore, the stamping component includes a stamping seat, and a stamping head is provided at the bottom of the stamping seat that is aligned with the stamping opening.

[0010] Furthermore, a pressure hole is provided at the upper end of the outer mold area, a guide groove is provided at the bottom of the stamping seat, a guide block is sleeved inside the guide groove, a spring is provided between the guide block and the bottom of the guide groove, a limiting ring is provided at the groove opening to prevent the guide block from disengaging, a pressure rod extends from the bottom of the guide block, the pressure rod is coaxial with the pressure hole, and during stamping, the pressure rod contacts the square aluminum profile before the stamping head.

[0011] Furthermore, the four inner edges of the opening of the middle support block facing the left support column are chamfered. The auxiliary components include a support seat located directly below the material drop port and a spring that drives the support seat to move upward. Initially, the upper end face of the support seat is flush with the lower opening of the material drop port. The auxiliary components also include auxiliary components.

[0012] Furthermore, the auxiliary components include a fixed column mounted on the frame and parallel to the support column, with a push sleeve sleeved on the outside of the fixed column. The push sleeve is driven by a telescopic rod and moves on the fixed column. When the stamping is completed, the stamped-down scrap is directed towards the push sleeve.

[0013] Furthermore, the fixed column is hollow inside and equipped with clamping components. When the stamping is completed, the punched-out scrap is facing the push sleeve. At this time, the scrap can be clamped internally by the clamping components.

[0014] A stamping method for an aluminum profile stamping die includes the following steps: Step 1: Place the square aluminum profile in the outer mold area, with the support mechanism in the avoidance position located inside the square aluminum profile; Step 2: The clamping components remove their internal clamping of the central support block, left support column, and right support column, and move away from the central support block and right support column, so that the support mechanism switches to the support state; Step 3: Stamping of the square aluminum profile tube is achieved through stamping components; Step 4: When the stamping is completed, the punched-out scrap is located on the support base, the middle support block is located inside the scrap, the stamping head is stationary, the clamping component applies internal clamping to the middle support block, then the stamping head remains stationary, the telescopic rod drives the push sleeve to move and push the scrap away, then the push sleeve retracts to reset, at this time the middle support block is located between the stamping head and the support base, then the clamping component removes internal clamping, at this time the middle support block is pressed between the stamping head and the support base, then the stamping head moves up to reset, and as soon as the spring releases its elastic force, the support base moves up with the middle support block, finally making the lower end face of the middle support block flush with the lower opening of the blanking port; Step 5: The clamping component operates, achieving internal clamping of the central support block, left support column, and right support column, and the support mechanism switches to the avoidance state.

[0015] In the above process, the processed aluminum profile can be directly extracted from between the outer mold area and the support column using existing robotic arm technology, or the support column can be pulled back by a linear module for unloading, and then the support column can be pulled forward to reset.

[0016] Compared with the prior art, the beneficial effects of this invention are as follows: This solution can be applied not only to punching square aluminum profiles but also to punching holes in them. The only difference lies in the shape of the punching head and the punch opening, which differ depending on whether it is punching or punching. Compared to existing cutting machine technology, the punching method can greatly improve the processing efficiency of photovoltaic frames. Furthermore: 1. In this solution, the aluminum profile is supported from the outside by the outer mold area and from the inside by the support column. Therefore, during stamping, the problem of easy denting of the stamping surface can be solved, making the stamping surface smooth and flat, and the quality of the processed photovoltaic frame is better. 2. In this solution, the internal and external support and stamping of the square aluminum profile are all automated operations, requiring no manual assistance, which is more intelligent and frees up manpower; 3. In this solution, the clamping assembly and clamping parts are clamped or released by moving the connecting seat through a hydraulic rod. The structure is simple, easy to operate, and small in size. It can be installed in the support column to achieve internal clamping of the support column, thus realizing the internal and external clamping in this solution. Attached Figure Description

Detailed Implementation

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] This solution can not only punch the aluminum profile tube, but also punch the aluminum profile tube. The only difference is that the shape of the punching head and the punching hole are different depending on whether it is punching or punching. The former will be used as an example in the following text.

[0021] In this solution, the linear module can be based on electric telescopic pole technology, hydraulic pole technology, or lead screw linear motion technology, etc., which will not be elaborated further.

[0022] Reference Figures 1-12 An aluminum profile stamping die includes a frame 100, on which a stamping component 200, a support mechanism 300, and an auxiliary component 400 are mounted, wherein: The support mechanism 300 is configured to switch between an avoidance state and a support state. When in the avoidance state, the inner support component 303 in the support mechanism 300 is an integrated structure for feeding square aluminum profiles. When in the support state, the support mechanism 300 is used to support the square aluminum profiles from both inside and outside without affecting the subsequent stamping process. The stamping component 200 is used to stamp the square aluminum profile on the support mechanism 300; The auxiliary component 400 is used to assist the support mechanism 300 in switching from the support state to the avoidance state.

[0023] Supporting institution 300: Reference Figures 3-6 The support mechanism 300 includes a mold frame 301 mounted on the frame 100. An outer support component and an inner support component 303 are mounted on the mold frame 301. The former is used to support the square aluminum profile from the outside, and the latter is used to support the square aluminum profile from the inside, thus solving the problem that the stamping surface is prone to denting when the square aluminum profile is stamped.

[0024] Reference Figure 7 The external support component includes an outer mold area 3011 that is horizontally arranged and runs through the mold frame 301. The upper and lower sides of the outer mold area 3011 are provided with notches. The upper notch is a stamping port 3012 and the lower notch is a blanking port.

[0025] Reference Figure 8 and Figure 9The inner support component 303 includes a support column with one end open and the other end closed. The center line of the support column coincides with the center line of the outer mold area 3011. The support column includes a middle support block 3032 located in the outer mold area 3011 and a left support column 3031 and a right support column 3033 respectively disposed at both ends of the middle support block 3032. The left support column 3031 is connected to the mold frame 301. The left support column 3031 and the middle support block 3032 are open at both ends. The right support column 3033 is open at one end and closed at the other end. Preferably, in order to facilitate the removal of aluminum profiles after stamping, the mold frame 301 is provided with a linear module 302 for driving the left support column 3031 to move along the extension direction.

[0026] The support column is equipped with a clamping component. When the support mechanism 300 is in the avoidance state, the clamping component applies internal clamping to the middle support block 3032, the left support column 3031 and the right support column 3033 at the same time, so that the three are integrated into a single structure. When the support mechanism 300 is in the support state, the clamping component removes the internal clamping and retracts into the left support column 3031, without affecting the subsequent stamping process.

[0027] Specifically, refer to Figure 9 and Figure 10 The clamping assembly includes a connecting seat 3035 sleeved inside the left support column 3031 and a hydraulic rod 3034 for driving the connecting seat 3035 to move within the left support column 3031. An outer clamping sleeve 3037 is slidably connected to the side of the connecting seat 3035 facing the middle support block 3032, and a spring 3036 is provided between the outer clamping sleeve 3037 and the connecting seat 3035.

[0028] An inner sliding column 3038 is slidably installed inside the outer sleeve 3037 along the center line of the support column. One end of the inner sliding column 3038 extends between the outer sleeve 3037 and the connecting seat 3035, and a spring 3039 is provided between this end of the inner sliding column 3038 and the outer sleeve 3037.

[0029] The outer sleeve 3037 has an inlay groove on its side, and a clamping plate 304 is installed in the inlay groove. A bracket extends from the inner side of the clamping plate 304. The bracket and the outer sleeve 3037 are in sliding fit, and the sliding direction is perpendicular to the side of the outer sleeve 3037 where the inlay groove is provided. A protruding pin is provided on the bracket, and a linkage hole is provided on the inner sliding column 3038. The end of the protruding pin slides in the linkage hole. The linkage hole is arranged at an angle, and the distance between it and the center line of the support column decreases along the direction from the left support column 3031 to the middle support block 3032.

[0030] When the hydraulic rod 3034 drives the connecting seat 3035 to move closer to the closed end of the support column, initially, the connecting seat 3035 pushes the outer sleeve 3037 and the inner sliding column 3038 together through the spring 3036. When the outer sleeve 3037 contacts the closed end of the support column, the outer sleeve 3037 stops moving. After that, the connecting seat 3035 will push the inner sliding column 3038 to continue moving. The spring 3036 and the spring 4 3039 are compressed. At the same time, with the cooperation of the linkage hole and the protrusion, the clamping plate 304 is driven to extend outward. Finally, the clamping plate 304 achieves the internal clamping of the support column. It should be noted that there are several clamping plates 304 in the array, so they can simultaneously apply internal clamping to the middle support block 3032, the left support column 3031 and the right support column 3033 that make up the support column. In this way, the three can be integrated into a structure. At this time, the support mechanism 300 is in a clearance state. Conversely, when the hydraulic rod 3034 drives the connecting seat 3035 to move away from the closed end of the support column, the spring 3036 and the spring 4 3039 will release their elastic force, and the clamping plate 304 will release its clamping force until the clamping assembly is completely separated from the middle support block 3032 and the right support column 3033. At this time, the support mechanism 300 is in a supported state.

[0031] Stamped component 200: Reference Figures 4-6 The stamping component 200 includes a stamping seat 201. The bottom of the stamping seat 201 is provided with a stamping head 202 located on the same straight line as the stamping opening 3012. The stamping seat 201 is driven to move in the vertical direction using existing hydraulic technology, thereby driving the stamping head 202 to perform the stamping action.

[0032] In a preferred embodiment, the support mechanism 300 in a supported state applies support from both the inner and outer sides of the square aluminum profile. During the stamping process achieved by the stamping head 202, the left support column 3031 is connected to the linear module 302 and remains stationary; the middle support block 3032 corresponds to the stamped scrap portion and is therefore ultimately located within the stamped scrap, thus requiring no fixing; the right support column 3033 needs to be limited to prevent it from swaying during stamping and failing to provide support. Therefore, referring to... Figure 5 and Figure 6The upper end of the outer mold area 3011 is provided with a pressure hole 3013. The bottom of the stamping seat 201 is provided with a guide groove, and a guide block is sleeved in the guide groove. A spring 204 is provided between the guide block and the bottom of the guide groove. The guide block is restricted by a limiting ring set at the opening of the guide groove and will not detach from the guide groove. A pressure rod 203 extends from the bottom of the guide block. The pressure rod 203 is coaxial with the pressure hole 3013. The advantage of this is that during stamping, before the stamping head 202 contacts the square tube aluminum profile, the pressure rod 203 passes through the pressure hole 3013 and contacts the aluminum profile first. Then, it presses against the aluminum profile, thereby pressing against the aluminum profile and the right support column 3033 and preventing the right support column 3033 from shaking during the stamping process.

[0033] Auxiliary component 400: Reference Figure 5 and Figure 6 The auxiliary component 400 includes a support base 401 located directly below the material discharge port and a spring 402 that elastically drives the support base 401 to move upward. Initially, the upper end face of the support base 401 is flush with the lower opening of the material discharge port.

[0034] The auxiliary component 400 also includes an auxiliary component 403. During stamping, the scrap material is located on the support base 401 and is pushed down by the stamping action. When the stamping ends, the scrap material is completely separated from the aluminum profile and is located on the support base 401. At this time, the middle support block 3032 is located in the scrap material. Therefore, the auxiliary component 403 is needed to make the scrap material leave the middle support block 3032.

[0035] Reference Figure 11 and Figure 12 The auxiliary component 403 includes a fixed column 4031 mounted on the frame 100 and parallel to the support column. A push sleeve 4032 is sleeved on the outside of the fixed column 4031. The push sleeve 4032 is driven by the telescopic rod 4033 and moves on the fixed column 4031. When the stamping is completed, the punched-out waste material is directly opposite the push sleeve 4032 and can be pushed away by the push sleeve 4032. The telescopic rod 4033 can adopt modern electric telescopic rod technology.

[0036] The fixed column 4031 is hollow inside and equipped with a clamping component 4034. The structure of the clamping component 4034 is consistent with the structure of the clamping assembly. When the stamping is completed, the punched-out scrap is directly facing the push sleeve 4032. At this time, the stamping head 202 does not move initially, and the clamping component 4034 applies internal clamping to the middle support block 3032. Afterward, the stamping head 202 remains stationary, and the telescopic rod 4033 drives the push sleeve 4032 to move, pushing away the scrap. Then, the push sleeve 4032 retracts and resets, and the spring 402 releases part of its elastic force. The middle support block 3032 is located between the stamping head 202 and the support base 401. Afterward, the clamping component 4034 releases the internal clamping. At this time, the middle support block 3032 is pressed between the stamping head 202 and the support base 401. Between 01 and 02, finally, the stamping head 202 moves upward and resets, while the spring 402 releases its elastic force. The support base 401 moves upward with the middle support block 3032. Finally, the clamping assembly operates to achieve internal clamping of the support column, making it an integrated structure. It should be noted that during the process of the support base 401 moving upward with the middle support block 3032, the lower end face of the middle support block 3032 can only be flush with the lower opening of the material discharge port. Therefore, it is necessary to chamfer the four inner edges of the opening of the middle support block 3032 facing the left support column 3031. The opening is in the shape of a ring. The inner edge refers to the four sides of the opening facing inward. The chamfer will form a slope. Under the guidance of the slope, during the clamping action of the clamping assembly, the outer clamp 3037 will float upward and finally achieve reset.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present invention.

The stamping method of an aluminum profile stamping die as described in claim 7, characterized in that, Includes the following steps: Step 1: Place the square aluminum profile in the outer mold area (3011), and the support mechanism (300) in the avoidance state is located inside the square aluminum profile; Step 2: The clamping components remove their internal clamping of the central support block (3032), left support column (3031) and right support column (3033), and move away from the central support block (3032) and right support column (3033), so that the support mechanism (300) switches to the support state; Step 3: Stamp the square aluminum profile tube using the stamping component (200); Step 4: When the stamping is completed, the punched-out scrap is located on the support base (401), the middle support block (3032) is located inside the scrap, the stamping head (202) remains stationary, and the middle support block (3032) is internally clamped by the clamping component (4034). After that, the stamping head (202) remains stationary, and the telescopic rod (4033) drives the push sleeve (4032) to move, pushing the scrap away. After that, the push sleeve (4032) retracts and resets. At this time, the middle support block (3032) Located between the punch head (202) and the support base (401), the clamping component (4034) then removes the inner clamping. At this time, the middle support block (3032) is pressed between the punch head (202) and the support base (401). Then, the punch head (202) moves up and resets, while the spring (402) releases its elastic force. The support base (401) moves up with the middle support block (3032), eventually making the lower end face of the middle support block (3032) flush with the lower opening of the blanking port. Step 5: The clamping component operates to achieve internal clamping of the central support block (3032), the left support column (3031) and the right support column (3033), and the support mechanism (300) switches to the avoidance state.
