Description

Technical Field

[0001] This application relates to the field of processing equipment technology, and more specifically, it relates to a punching device for hardware parts. Background Technology

[0002] In the hardware processing industry, aluminum alloy sheets are a commonly used hardware component. Due to their lightweight, suitable strength, and good corrosion resistance, they are widely used in various industries such as construction, automobiles, and electronics. To meet the subsequent assembly, connection, or other functional requirements of aluminum alloy sheets, a punching process is usually required. While traditional punching devices can perform basic punching operations, in actual production applications, not only is it necessary to manually adjust the processing position of the aluminum alloy sheet repeatedly before punching, but also, after the punching device completes the punching process, the processed aluminum alloy sheet needs to be manually removed from the work area for the next round of processing. This manual material handling method not only increases the labor intensity of operators but also makes it difficult to meet the needs of large-scale, continuous production. Utility Model Content

[0003] To address the shortcomings of the existing technology, the purpose of this application is to provide a punching device for hardware parts, including a frame and an aluminum alloy plate horizontally mounted on the top of the frame. The frame is provided with at least one punching mechanism for punching holes in the aluminum alloy plate, and the frame is also provided with at least one pushing mechanism for pushing the punched aluminum alloy plate. The pushing mechanism is located on one side of the punching mechanism. The pushing mechanism includes a mounting bracket installed at the bottom of the frame, and a first cylinder is installed on the inner wall of the mounting bracket. One end of the first cylinder drives a pushing block for pushing the aluminum alloy plate. On the other side of the punching mechanism, a blocking mechanism for blocking the aluminum alloy plate is provided. The blocking mechanism includes a fixed seat installed at the top of the frame and a column installed on the fixed seat. A blocking block is movably sleeved on the outside of the column.

[0004] Preferably, the punching mechanism includes a work frame mounted on the top of the machine frame and a second cylinder mounted on the top of the work frame. The work frame is equipped with a lifting plate that is driven and connected to the second cylinder. A set of punches for punching aluminum alloy plates is provided on both sides of the bottom of the lifting plate.

[0005] Preferably, the punching mechanism further includes multiple pressure blocks for pressing and limiting the aluminum alloy plate, and the pressure blocks are respectively located on both sides of the bottom of the lifting plate, and the punch penetrates through the pressure block and moves inside the pressure block.

[0006] Preferably, multiple bolts are equidistantly inserted on both sides of the top of the lifting plate, with one end of each bolt penetrating the lifting plate and threadedly connected to the pressure block, and a spring is sleeved on the outside of the bolt.

[0007] Preferably, multiple positioning posts are equidistantly arranged on both sides of the bottom of the lifting plate, and multiple positioning holes are equidistantly opened on both sides of the top of the frame, with the positioning posts and positioning holes being inserted into each other.

[0008] Preferably, the material blocking mechanism further includes a third cylinder disposed on the side of the fixed base, and one end of the third cylinder is driven and connected to a connecting member, and the other end of the connecting member is hinged to the material blocking block.

[0009] Preferably, a sliding groove is provided at the bottom of the mounting frame, and the pusher block slides in cooperation with the sliding groove.

[0010] Preferably, the top of the pusher block is inclined.

[0011] In summary, the beneficial effects of this application are as follows:

[0012] 1. After the aluminum alloy sheet is placed on top of the frame, the punching mechanism can be driven to punch the sheet. After punching, the first cylinder drives the pusher block to move towards the aluminum alloy sheet until it pushes the sheet off the frame and is removed, allowing for subsequent processing. This method of material removal using the first cylinder and the pusher block replaces manual handling, reducing the workload and effectively solving the problem that traditional punching devices, while capable of basic punching operations, require manual adjustment of the aluminum alloy sheet's position before punching and manual removal of the sheet after punching for the next round of processing. This manual removal method increases the labor intensity of operators and is difficult to meet the needs of large-scale, continuous production.

[0013] 2. When the third cylinder extends, it will drive the connecting piece to move towards the aluminum alloy plate. During this process, the stop block will be offset on the column under the action of the connecting piece until the stop block is offset counterclockwise by 45 degrees from the initial angle. At this time, the included angle of the stop block is the placement reference position of the aluminum alloy plate. Then, simply align the included angle of the aluminum alloy plate with the included angle of the stop block to complete the positioning of the aluminum alloy plate. Finally, the placed aluminum alloy plate can be punched by the punching mechanism. Through the cooperation between the third cylinder, the connecting piece, the column and the stop block, this embodiment eliminates the need for repeated manual adjustment of the aluminum alloy plate position.

[0023] A punching device for hardware parts, see Figures 1 to 4The system includes a frame 1 and an aluminum alloy plate 2 horizontally mounted on top of the frame 1. The frame 1 is equipped with at least one punching mechanism 3 for punching holes in the aluminum alloy plate 2, and also with at least one pushing mechanism 4 for pushing the punched aluminum alloy plate 2. The pushing mechanism 4 is located on one side of the punching mechanism 3. The pushing mechanism 4 includes a mounting bracket 401 installed at the bottom of the frame 1, and a first cylinder 402 is installed on the inner wall of the mounting bracket 401. One end of the first cylinder 402 is connected to a pushing block 403 for pushing the aluminum alloy plate 2. After the aluminum alloy plate 2 is placed on top of the frame 1, the punching mechanism 3 can be driven to punch holes in the aluminum alloy plate 2. In the punching process, after punching is completed, the first cylinder 402 drives the pusher block 403 to move towards the aluminum alloy plate 2 until the pusher block 403 pushes the aluminum alloy plate 2 off the frame 1 and completes the material removal, so that the aluminum alloy plate 2 can proceed to subsequent processing steps. The material removal method of the first cylinder 402 and the pusher block 403 working together can replace manual material removal, reducing the burden on workers and effectively solving the technical problem that although the traditional punching device can achieve basic punching operations, in actual production applications, after the punching device completes the punching of the aluminum alloy plate 2, it is still necessary to manually remove the processed aluminum alloy plate 2 from the work area for the next round of processing operations. However, this manual material removal method not only increases the labor intensity of operators, but also makes it difficult to meet the technical problems of large-scale, continuous production.

[0024] The punching mechanism 3 includes a work frame 301 mounted on the top of the frame 1, and a second cylinder 302 mounted on the top of the work frame 301. A lifting plate 303, driven and connected to the second cylinder 302, is provided inside the work frame 301. A set of punches 304 for punching aluminum alloy plates 2 are respectively provided on both sides of the bottom of the lifting plate 303. The punching mechanism 3 also includes multiple pressure blocks 305 for pressing and limiting the aluminum alloy plates 2. The pressure blocks 305 are located on both sides of the bottom of the lifting plate 303, and the punches 304 penetrate the pressure blocks 305 and move within the pressure blocks 305. Multiple bolts 306 are equidistantly inserted into the top two sides of the lifting plate 303. One end of bolt 306 passes through lifting plate 303 and is threadedly connected to pressure block 305, and spring 307 is sleeved on the outside of bolt 306; multiple positioning posts 308 are equidistantly arranged on both sides of the bottom of lifting plate 303, and multiple positioning holes 309 are equidistantly opened on both sides of the top of frame 1, with the positioning posts 308 and positioning holes 309 being inserted into each other; when aluminum alloy plate 2 is placed on top of frame 1, aluminum alloy plate 2 will be located below pressure block 305, and then the second cylinder 302 drives lifting plate 303 to move towards aluminum alloy plate 2, so that positioning posts 308 are first inserted into positioning holes 309 for positioning. Through the mutual cooperation between positioning posts 308 and positioning holes 309, a certain position can be achieved. To ensure the accuracy of the aluminum alloy plate 2's position during punching, and to avoid punching position deviations caused by the aluminum alloy plate 2's positional shift, the punching precision is greatly improved, ensuring product consistency. Next, the pressure block 305 contacts the aluminum alloy plate 2 and confines it between the pressure block 305 and the frame 1. During this process, the pressure block 305 synchronously drives the bolt 306 to move in the opposite direction of the aluminum alloy plate 2 within the lifting plate 303, compressing the spring 307 between the lifting plate 303 and the pressure block 305. The elastic force of the spring 307 continuously acts on the pressure block 305, providing stable pressure and thus fixing the aluminum alloy plate 2, effectively preventing the aluminum alloy plate 2 from shifting during punching. During the punching process, any shaking or displacement occurs, ensuring stability. Furthermore, the spring 307's buffering effect prevents the pressure block 305 from causing hard damage to the aluminum alloy plate 2, protecting its surface quality. Finally, the punch 304, driven by the lifting plate 303, penetrates the pressure block 305 and punches the aluminum alloy plate 2. Through the cooperation of these structures, the aluminum alloy plate 2 remains stable during punching, reducing punching deformation and burrs caused by shaking, thus improving punching quality. Moreover, the second cylinder 302's drive effectively enhances automation, reduces manual intervention, and improves overall punching efficiency, meeting the needs of mass production.

[0025] On the other side of the punching mechanism 3, a material-blocking mechanism 5 is provided for blocking the aluminum alloy plate 2. The material-blocking mechanism 5 includes a fixed base 501 located on the top of the frame 1 and a column 502 located on the fixed base 501. A material-blocking block 503 is movably sleeved on the outside of the column 502. The material-blocking mechanism 5 also includes a third cylinder 504 located on the side of the fixed base 501. One end of the third cylinder 504 is driven and connected to a connecting member 505, and the other end of the connecting member 505 is connected to the material-blocking block. 503 is hinged; in this embodiment, the stop block 503 is L-shaped, and when the third cylinder 504 is not extended, the angle at which the stop block 503 is positioned is its initial angle. When the third cylinder 504 extends, it drives the connecting piece 505 to move towards the aluminum alloy plate 2. During this process, the stop block 503 will be offset on the column 502 under the action of the connecting piece 505 until the stop block 503 is offset counterclockwise by forty-five degrees from its initial angle. At this point, the included angle of the stop block 503 is the placement reference position of the aluminum alloy plate 2. Then, simply align the included angle of the aluminum alloy plate 2 with the included angle of the stop block 503 to complete the positioning of the aluminum alloy plate 2. Finally, the punching mechanism 3 can then punch the placed aluminum alloy plate 2. Through the cooperation between the third cylinder 504, the connector 505, the column 502, and the stop block 503, this embodiment eliminates the need for repeated manual adjustments to the position of the aluminum alloy plate 2, effectively avoiding inaccurate punching positions caused by manual placement deviations and significantly improving the punching accuracy of the aluminum alloy plate 2. In addition, in practical applications, the placement reference position of the aluminum alloy plate 2 may deviate slightly due to wear and tear of various parts over a long period of use. Therefore, the placement reference position of the aluminum alloy plate 2 can be determined by repeatedly adjusting the offset angle of the stop block 503. In this embodiment, the offset angle of the stop block 503 is a reference value, and the specific offset angle needs to be determined based on the actual offset angle adjusted on site.

[0026] The mounting frame 401 has a sliding groove 6 at its bottom, and the pusher block 403 slides in conjunction with the sliding groove 6. By providing the sliding groove 6, the stability of the pusher block 403 during movement can be effectively improved, and the pusher block 403 can be prevented from deviating during the pushing process. In this embodiment, the top of the frame 1 is provided with a guide plate 7 at an angle. When the pusher block 403 pushes the aluminum alloy plate 2 off the frame 1, the aluminum alloy plate 2 will move to the guide plate 7 and be guided by the guide plate 7 to slide down along its inclined direction to the next process, thereby assisting the aluminum alloy plate 2 in completing the material picking. The top of the pusher block 403 is inclined, and the top side of the pusher block 403 near the guide plate 7 is lower than the top side of the pusher block 403 away from the guide plate 7. By designing the pusher block 403 to be inclined, the pusher block 403 can make smoother contact with the aluminum alloy plate 2 and apply pushing force when pushing the aluminum alloy plate 2.

[0027] The above embodiments are merely explanations of this application and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
