Description

Technical Field

[0001] The utility model relates to a polishing device for the upper die core of an aluminum profile extrusion die, belonging to the technical field of aluminum profile extrusion dies. Background Technique

[0002] The aluminum profile extrusion die is the core tool in the aluminum profile production process, mainly used to make aluminum materials into products of various specifications and shapes by extrusion. The design and manufacturing quality of the die directly affect the processing efficiency and product quality of aluminum profiles. Due to its advantages such as light weight, high strength, and corrosion resistance, aluminum profiles are widely used in many fields such as construction, transportation, and electronics. In order to ensure the accuracy and appearance quality of the formed products, it is necessary to polish and grind the surface of the die core after production.

[0003] Chinese Patent Publication (Publication No.: CN 217168017 U) discloses a die polishing device, including a handle. A partition is fixed inside the handle. A driving motor and a micro water pump are respectively fixed on the lower surface and the upper surface of the partition. The outer side wall of the bottom end of the handle is fixed with a telescopic structure, and the telescopic structure includes a fixed rod fixed on the outer side wall of the handle. An activity groove is opened on the side of the fixed rod away from the handle, and a telescopic rod is slidably connected inside the activity groove. In the utility model, there are provided a handle, a driving motor, a micro water pump and a telescopic structure. The telescopic structure includes a fixed rod and a telescopic rod. The telescopic rod slides in the activity groove of the fixed rod. A grinding disc is provided at the bottom end of the telescopic rod. The driving motor and a belt can drive the grinding disc to rotate and perform grinding operations. At this time, the length of the telescopic structure can be flexibly adjusted according to the depth of the position of the die that needs to be ground, and the belt of the corresponding length can be replaced to improve the flexibility of the device;

[0004] However, when polishing and grinding the die core with the above technology, due to the die core being too large or too small, it may not be stably fixed, resulting in the die core being loose or unable to be stably placed on the surface of the grinding table, thus unable to achieve a good grinding effect. If the die core cannot be stably fixed, the polishing effect will become poor and the accuracy of the die core will become low, affecting the subsequent product processing.

At this time, the position of the fixing block 401 can be adjusted back and forth according to the size of the die core. After completion, release the moving rod 1301, and the connecting rod 1302 is inserted back into the fixing groove 14 by the resilience of the tension spring 1303.
