TECHNICAL FIELD

[0001] The utility model belongs to aluminum door and window processing device technical field, especially relate to a aluminum door and window section bar punch press. BACKGROUND

[0002] Aluminum alloy door and window refers to the door and window made of aluminum alloy extruded section bar as frame, shaft and fan material, which is called aluminum alloy door and window for short. Aluminum alloy door and window includes door and window made of aluminum alloy as force rod (rod bearing and transmitting dead weight and load) base material and wood and plastic composite, which is called aluminum-wood composite door and window and aluminum-plastic composite door and window for short. The quality of aluminum alloy door and window can be roughly judged from aspects such as selection of raw material (aluminum section bar), surface treatment of aluminum material and internal processing quality, price of aluminum alloy door and window. In the process of extruding aluminum alloy door and window, a corresponding punch device is often needed to punch it.

[0003] For example, the Chinese patent with publication number CN217700880U discloses an aluminum door and window section bar punch equipment, which comprises a workbench, a mounting groove is formed in the top of the workbench, a mounting plate is arranged in the mounting groove, the outer wall of the mounting plate is attached to the inner wall of the mounting groove, T-shaped blocks are fixedly connected to the bottom of the mounting plate at both ends, two recesses are formed in the bottom of the mounting groove, two symmetrically arranged connecting frames are fixedly connected in the two recesses, guide rods are fixedly connected in the two connecting frames, the two ends of the bottom of the T-shaped block are arranged on the outer sides of the guide rods, a compression spring is fixedly connected to the middle of the bottom of the T-shaped block, and one end of the compression spring is fixedly connected to the bottom of the recess. The aluminum door and window section bar punch equipment can unload the impact force generated during punching, reduce the impact force received by the workbench and the lower die plate, and prolong the service life of the punch equipment.

[0004] The patent has some shortcomings when in use, such as: the device can only process aluminum doors and windows in a single way because the die plate is fixed in the device, which has low applicability and cannot meet the various needs of the market and customers. In addition, the device does not have a corresponding auxiliary correction mechanism, and the section bars located on the outer side are prone to tilting after being stressed during punching, which reduces the precision of the punched section bars and cannot meet the use requirements. In view of this, we propose a aluminum door and window section bar punch press. UTILITY MODEL CONTENTS
