Description

Technical Field

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

[0002] Aluminum alloy doors and windows are windows with extruded aluminum alloy profiles as the main frame structure. They have ventilation, light transmission, sealing, sound insulation, and heat preservation properties. According to the opening method, they are divided into casement, sliding, folding, and top-hung types, and are widely used in various fields. Drainage holes are often required on the bottom profile of aluminum alloy doors and windows to drain rainwater.

[0003] Patent No. ZL 202422286632.0 discloses a punching machine for drainage holes in doors and windows. A first clamping plate directly abuts against the surface of the door and window profile, while a second clamping plate abuts against the profile via a support frame, providing support to the bottom of the punched area. This effectively prevents deformation of the door and window profile during punching, avoiding subsequent straightening and improving punching efficiency. However, the aforementioned patent lacks clamping components at the punched surface of the door and window profile. If the punched area is warped or bent, it can easily lead to insufficient punching stability, thus affecting processing accuracy. Summary of the Invention

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A punching device for aluminum alloy doors and windows includes a base, a profile disposed above the base, a frame disposed above the profile, and a punching machine disposed on the frame. The punching machine is arranged facing downwards and is connected to a punching mechanism. A positioning mechanism and a clamping mechanism are respectively provided on the left and right sides of the profile. The positioning mechanism and the clamping mechanism are slidably connected to the base on the left and right sides. The device is characterized in that: The punching mechanism includes a hollow punching seat, a punch located inside the punching seat, and a pressure head sleeved on the outside of the punch.

The outer side of the pressure head 7 is vertically slidably connected to the through hole 8, and a preload spring 9 is provided between the pressure head 7 and the top of the punching seat 5. The clamping mechanism includes a horizontally extending support plate 10. The support plate 10 is inserted into the inner side of the profile 2 and abuts against the bottom of the punched part of the profile 2. The support plate 10 is provided with a vertical through punch groove 11. The punch groove 11 is matched and positioned with the punch 6.

[0016] Profile 2 is located above base 1 and has a track-like structure, arranged along the front-to-back direction. For ease of processing, profile 2 is placed sideways with its opening facing right. The left side of profile 2 has a corresponding planar structure, and the right side has a corresponding groove. Drainage holes are formed by punching holes on the upper surface of profile 2. The drainage holes are connected to the grooves on the inner side of profile 2. The punching location of the drainage holes is the punching point of profile 2. Frame 3 is located above profile 2, spaced apart from profile 2, and fixedly connected to base 1. Press 4 is located on frame 3. Frame 3 has a vertical through hole in its center. Press 4 is positioned downwards, with its telescopic end passing through the through hole and connected to the punching mechanism. Positioning mechanism is located on the left side of profile 2, corresponding to the planar structure of profile 2, and is slidably connected to base 1. After the positioning mechanism moves to the right, it can abut against the left side of profile 2. The clamping mechanism is located on the right side of profile 2, corresponding to the groove structure of profile 2, and is slidably connected to the base 1. After the positioning mechanism moves to the left, it can abut against the right side of profile 2. Through the cooperation of the positioning mechanism and the clamping mechanism, the left and right sides of profile 2 are clamped to achieve horizontal constraint.

[0017] The punching seat 5 is located below the frame 3, facing downwards, and has a hollow internal structure with a downward-opening cavity. The top of the punching seat 5 connects to the telescopic end of the press 4, which drives the punching seat 5 to move vertically up and down. The bottom of the punching seat 5 has a vertically penetrating through-hole 8, which communicates with the interior of the punching seat 5. The punch 6 is located inside the punching seat 5, facing downwards, and corresponds to the size of the drain hole. The top of the punch 6 connects to the top of the punching seat 5, and their centers are aligned. The bottom of the punch 6 extends downwards through the through-hole 8, corresponding to the punching position of the profile 2. The pressure head 7 is located inside the punching seat 5, facing downwards, and is fitted onto the outside of the punch 6. The pressure head 7 is inserted into the through-hole 8, and its top has an outwardly extending flange. The top of the pressure head 7 engages with the interior of the punching seat 5 through the flange, serving a limiting function. The bottom end of the pressure head 7 extends downward through the through hole 8 and downward relative to the bottom end of the punch 6, ensuring that the pressure head 7 abuts against the profile 2 before the punch 6 punches it. The preload spring 9 is located inside the punching seat 5 and is vertically positioned.

The support plate 10 is inserted into the inside of profile 2, abutting against the bottom of the punched area and vertically aligned with the punch 6. The pressure head 7 cooperates with the support plate 10 to clamp the upper and lower sides of the punched area of ​​profile 2, achieving vertical constraint.

[0018] By setting up a punching mechanism, when punching the profile 2 is required, the profile 2 is first placed on top of the base 1. The positioning mechanism and clamping mechanism slide left and right, clamping the profile 2 between them, corresponding to the position of the punching mechanism. The support plate 10 is inserted into the inside of the profile 2 and abuts against the bottom of the punched area of ​​the profile 2 to achieve the support function. Then, the punching machine 4 drives the punching seat 5 to move downward, and the bottom end of the pressure head 7 abuts against the surface of the punched area of ​​the profile 2. The pressure head 7 slides relative to the through hole 8, compressing the pre-compression spring 9. The spring force is used to press down on the surface of the punched area of ​​the profile 2 to achieve the pre-compression function. Finally, the pressure head 7 gradually retracts into the punching seat 5, and the bottom end of the punch 6 abuts against the surface of the punched area of ​​the profile 2, thus pressing down to complete the punching operation. The support plate 10 and the pressure head 7 stably clamp the punched area of ​​the profile 2, avoiding insufficient stability caused by warping or bending, and effectively improving the processing accuracy.
