Description

Technical Field

[0001] This utility model relates to the field of winding machine mold technology, specifically a quick mold changing device for a winding machine. Background Technology

[0002] A finned tube winding machine is a device used to produce finned tubes. It mainly forms efficient heat exchange elements by winding metal strips (such as aluminum strips, steel strips, etc.) around a base tube (such as steel tubes, copper tubes, etc.). The finned tube winding die plays a very important role in the winding machine. It is mainly used to determine the shape and size of the metal strip to be wound, ensuring that the metal strip can be tightly and evenly wound on the base tube.

[0003] During the processing, it is necessary to ensure the mold is fixed. Different molds are required for different base tube diameters or different winding sizes, so mold replacements occur frequently. The common method of fixing the mold with bolts can ensure the stability of the mold, but the disassembly and assembly process requires special disassembly and assembly tools and is slower. Furthermore, the integrated winding mold requires complete disassembly for any change in base tube size or winding size, which further increases the difficulty of operation. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-5 This utility model provides a technical solution: including a mold mounting frame 1, a vertical plate 2, a base tube mold 3, and a winding mold 4 installed on a winding machine. The mold mounting frame 1 has a T-shaped structure. The vertical plate 2 is installed upright on the mold mounting frame 1. A circular hole 21 is provided on the vertical plate 2. The base tube mold 3 and the winding mold 4 are respectively installed on both sides of the vertical plate 2 and their positions are aligned with the circular hole 21. Both the base tube mold 3 and the winding mold 4 have a circular ring structure. A feeding groove 41 is provided on the side wall of the winding mold 4. The base tube mold 3 is fixed on the vertical plate 2. A quick-release assembly is provided between the winding mold 4 and the vertical plate 2.

[0020] A pair of insert blocks 25 are fixed to the lower side wall of the upright plate 2. A slot 11 is opened on the top of the mold mounting frame 1 at the position corresponding to the insert blocks 25. The insert blocks 25 are inserted into the slot 11. A positioning hole 22 is opened on the upright plate 2 at the position aligned with the top of the mold mounting frame 1. An installation groove 12 is opened on the top of the mold mounting frame 1 at the position corresponding to the positioning hole 22. A rotating insert plate 13 is rotatably connected in the installation groove 12. The outer periphery of the rotating insert plate 13 is inserted into the positioning hole 22. The rotating insert plate 13 has a semi-circular structure and its diameter is greater than the upper width of the mold mounting frame 1. The distance from the center of the rotating insert plate 13 to the outer plane is less than half the upper width of the mold mounting frame 1. A baffle 14 is installed at the bottom of the installation groove 12. The upper side wall of the baffle 14 abuts against the outer plane of the rotating insert plate 13. A vertical groove is opened at the bottom of the installation groove 12 at the position corresponding to the baffle 14. A first spring is provided between the bottom of the vertical groove and the baffle 14.

[0021] The quick-release assembly includes a combination groove 23, a combination block 42, a stabilizing block 24, and a stabilizing groove 43. The combination groove 23 is opened on the side wall of the upright plate 2 and is equidistantly distributed around the circular hole 21. The combination block 42 is fixed on the side wall of the winding mold 4 and is aligned with the combination groove 23. The combination block 42 is inserted into the combination groove 23. The stabilizing groove 43 is opened on the periphery of the winding mold 4. The stabilizing block 24 is installed on the upright plate 2 and is aligned with the stabilizing groove 43. The stabilizing block 24 is inserted into the stabilizing groove 43. The combination block 42 has a T-shaped structure, and the stabilizing groove 43 has an arc structure, with one end being larger than the middle position. A horizontal groove is opened on the upright plate 2 at a position corresponding to the stabilizing block 24. A second spring is fixed between the inner side wall of the horizontal groove and the stabilizing block 24.

[0022] Working principle: First, align the insert 25 on the upright plate 2 with the slot 11 and insert it. This allows the upright plate 2 to adhere to the side wall of the mold mounting bracket 1. After full insertion, rotate the insert 13 to align it with the positioning hole 22. Rotating the insert 13 allows its arc-shaped end to be inserted into the positioning hole 22, limiting the vertical position of the upright plate 2 and thus achieving the purpose of the upright plate 2. At this time, the first spring will lift the baffle 14, and the side wall of the baffle 14 will abut against the plane side of the rotating insert 13, preventing the rotation of the rotating insert 13 and ensuring the stability of the upright plate 2 after fixing. Secondly, when installing the winding mold 4, the assembly block 42 can be inserted from the end of the assembly slot 23 and rotated at a certain angle. Since the assembly block 42 is... The T-shaped structure, with its end only insertable from the end of the combination groove 23, prevents the combination block 42 from being pulled out of the combination groove 23 after a certain rotation angle. This ensures the fit between the winding mold 4 and the upright plate 2. After a certain rotation angle, the position of the stabilizing block 24 will align with the position of the stabilizing groove 43. At this time, the second spring pushes the end of the stabilizing block 24 out and inserts it into the stabilizing groove 43, preventing the rotation of the winding mold 4 and achieving the purpose of fixing. The entire installation process uses a snap-fit ​​fixing method, and no disassembly or assembly tools are required, making the operation simpler. When the diameter of the base tube changes, the entire assembly is disassembled and the upright plate 2 with the base tube mold 3 of the specified inner diameter is replaced. When the winding size changes, only the winding mold 4 needs to be replaced independently, making the operation even simpler.
