In this embodiment, when the lower positioning position 20 does not move and the roll-wrapping device 2 moves, for example, when the roll-wrapping device 40 completes the roll-wrapping of the side 510 of the side panel 51 with respect to the side panel 50, the expansion and contraction block The device 6 is extended and inserted into the bottom hole 2010 of the lower positioning device 20, thereby preventing the lower positioning device 20 from being loaded and moving during the rolling process of the rolling device 40, ensuring that the lower positioning device 20 is effectively fixed and improving the volute The efficiency and quality of rolling hemming.
[0093] In this embodiment, as Figure 15 As shown, the telescopic blocking device 6 includes a seventh linear drive mechanism 60 provided on the frame 1, connected to a fixed end of the seventh linear drive mechanism 60 and provided with a fixing seat 61 on the frame 1, a device The guide shaft 62, which is on the fixed seat 61 and connected to the telescopic end of the seventh linear drive mechanism 60, is telescopically driven by the seventh linear drive mechanism 60 to expand and contract the guide shaft 62 so as to be inserted into the bottom hole 2010 of the lower positioning device 20 Or come out from the bottom hole 2010 of the lower positioning device 20. Preferably, the shaft end of the guide shaft 62 has a tapered structure to perform a guiding function during insertion. In this embodiment, the base 201 included in the lower positioning device 20 is provided with a bottom hole 2010.
[0094] In this embodiment, the seventh linear drive mechanism 60 may use existing linear motion drive equipment such as oil cylinders, air cylinders, and electric push rods.
[0095] This embodiment eliminates the welding pollution caused by the existing welding and the large consumption of electric energy, and because there are fewer welding spots, the original cold plate material volute can be changed to stainless steel or galvanized plate. The process of surface treatment can be omitted, and the production efficiency is improved while reducing the production cost.
[0096] It should be noted that in this article, the terms "include", "include" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, It also includes other elements not explicitly listed, or elements inherent to the process, method, article, or equipment.
[0097] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the industry should understand that the present invention is not limited by the above-mentioned embodiments. The above-mentioned embodiments and the description only illustrate the principles of the present invention. The present invention will have various aspects without departing from the spirit and scope of the present invention. Various changes and improvements, these changes and improvements fall within the scope of the claimed invention. The scope of protection claimed by the present invention is defined by the appended claims and their equivalents.
