Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy casting technology, and in particular to a punching device for aluminum alloy door and window profiles. Background Technology

[0002] Aluminum alloy doors and windows are very common in modern buildings. Due to their superior performance, good aesthetics, and relatively low maintenance costs, they are widely used in residential, commercial, and industrial buildings. Aluminum alloy doors and windows come in various profile types, with cross-sections including U-shaped, H-shaped, T-shaped, and L-shaped. These profiles often require drilling holes during assembly, and this drilling is typically done using a punching machine. A punching machine is a mechanical device that, after the raw materials are installed, uses a power mechanism to drive a punching die to act on the material, completing the punching process. Punching machines can perform sheet metal processing, stamping, die pressing, embossing, and other operations that force metal into the die.

[0003] Conventional punching machines are often equipped with a feeding rack to achieve precise displacement punching of aluminum alloy door and window profiles. However, this single-hole continuous processing method is time-consuming and the punching size is uniform. The hardware hole size of aluminum alloy door and window profiles varies, and the switching frequency during sequential punching is high. Conventional punching machines have difficulty in quickly switching punching sizes, and the punching rate will be greatly reduced after switching, affecting the overall processing efficiency of the profiles. Utility Model Content

[0004] The purpose of this invention is to provide a punching device for aluminum alloy door and window profiles, which can perform continuous and synchronous one-time punching operations on several profiles of the same type. Compared with the processing method of processing one hole sequentially and frequently switching punches, it is more efficient and stable, and improves the punching efficiency of profiles.

[0005] To achieve the above objectives, an aluminum alloy door and window profile punching device is provided, comprising: a base, a punching frame fixedly connected to the top rear side of the base, an electrically controlled guide rail fitted and fixedly mounted on the top of the punching frame in the left-right direction, a plurality of electric slides controlled by a PLC controller on the guide rail, an electric punching machine fitted and fixedly mounted on the front side of each electric slide, a placement plate horizontally mounted directly below the electric punching machine, the rear side of the placement plate being fixedly connected to the punching frame, a through groove vertically extending from the top center of the placement plate, a profile being placed against the top surface of the placement plate, electric positioning push rods symmetrically mounted on the left and right sides of the profile, clamping plates fixedly connected to the output ends of the opposite sides of the electric positioning push rods, the opposite sides of the clamping plates corresponding to the extrusion of the profile. The process involves mounting electrically controlled guide rails on the top left and right sides of the stamping frame to control several electric slides and correspondingly fix several independent electric punching machines for batch synchronous punching with adjustable left and right spacing. Then, a flat plate is horizontally mounted directly below these electric punching machines to place the profiles to be processed, and the profiles are clamped and fixed by electric positioning push rods mounted opposite each other with clamping plates, thus performing a one-time full punching process. There is no need to use a material feeding rack. Multiple punches are used, and the corresponding punches are selected according to the size of the hardware holes and arranged in sequence. Finally, the spacing of each punching point is controlled by PLC-assisted electrically controlled guide rails. After the preset is completed, several profiles of the same type can be continuously and synchronously punched in one go. Compared with the processing method of processing one hole at a time and frequently switching punches, it is more efficient and stable, improving the punching efficiency of profiles.

[0006] According to the aforementioned aluminum alloy door and window profile punching equipment, a waste discharge trough is provided below the through groove on the front side of the base, and the bottom layer of the waste discharge trough is inclined downward from back to front. Punching waste is allowed to fall freely into the waste discharge trough along the through groove and slide freely forward for recycling, preventing accumulation.

[0007] According to the aforementioned aluminum alloy door and window profile punching equipment, symmetrical pads are fixed to the left and right sides of the bottom front of the placement plate, and the bottom ends of the pads are fixed to the base. These pads provide auxiliary support to keep the placement plate horizontal and stable.

[0008] According to the aforementioned aluminum alloy door and window profile punching equipment, a rubber pad is attached to each opposite side of the clamping plate, and the rubber pad is elastically pressed against the left and right ends of the profile. This provides a certain degree of flexible contact protection when the profile is clamped in opposite directions.

[0009] According to the aforementioned aluminum alloy door and window profile punching equipment, small electric push rods are symmetrically fitted and fixed on the rear side of the punching frame. The front output ends of the small electric push rods slide out from the front side of the punching frame, and push plates are fixedly connected to them. The front side of the push plates corresponds to and fits against the profile. After completing the one-time punching process, the auxiliary machine pushes out the profile to prevent it from getting stuck on the placement plate and making it difficult to remove manually.

[0010] According to the aforementioned aluminum alloy door and window profile punching equipment, a limiting rod is horizontally mounted at the lower-middle position of the front side of the punching frame. The limiting rod is located behind the electric punching machine, and both its left and right ends are fixed to the punching frame. Several sliding sleeves are equidistantly fitted on the outer side of the limiting rod, and the front sides of the sliding sleeves are correspondingly fixedly connected to the electric punching machine. This assists in limiting the electric punching machine, keeping it vertically stable in the punching direction.

[0011] The above-mentioned solution has the following beneficial effects:

[0012] In this invention, electrically controlled guide rails are installed on the top left and right sides of the stamping frame to control several electric slides and correspondingly fix several independent electric punching machines for batch synchronous punching with adjustable left and right spacing. Then, a flat plate is horizontally placed directly below these electric punching machines to place the profiles to be processed, and the profiles are clamped and fixed by electric positioning push rods and clamping plates, thus performing a one-time full punching process. There is no need to equip a material feeding rack. Multiple punches are used, and the corresponding punches are selected according to the size of the hardware holes and arranged in sequence. Finally, the spacing of each punching point is controlled by PLC-assisted electrically controlled guide rails. After the preset is completed, several profiles of the same type can be continuously and synchronously punched in one go. Compared with the processing method of processing single holes sequentially and frequently switching punches, it is more efficient and stable, and improves the punching efficiency of profiles.
