Description

Technical Field

[0001] This invention relates to the field of outer cladding plate processing technology, and in particular to a processing method for sheet metal insulation outer cladding plates. Background Technology

[0002] The outer protective plate is a layer of stainless steel sheet wrapped around the outer surface of the metal cylinder. When the cylinder is placed outdoors, a cotton insulation pad needs to be wrapped around the outside of the cylinder to keep it warm. The outer protective plate is installed on the outside of the insulation pad to prevent the insulation pad from being directly exposed to the outside and getting wet, and also to make the cylinder more aesthetically pleasing.

[0003] Since the cylindrical cylinder body is mostly curved at both ends, and the actual cylinder body that needs to be wrapped is of different sizes, it is necessary to use sheet metal to splice together when wrapping the outer protective plate on the outside of the cylinder body to meet the requirements of the curved cylinder body.

[0004] The existing method of splicing sheet metal insulation panels involves connecting and fixing two adjacent sheets of sheet metal with connecting plates and rivets. This method of processing insulation panels not only requires more materials, but also results in a less than tight connection between adjacent sheets of sheet metal. Therefore, we propose a new processing method for sheet metal insulation panels. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a processing method for sheet metal insulation outer protective panels.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a processing method for a sheet metal insulation outer protective panel, which includes the following steps:

[0007] Step 1: Cut the sheet metal into multiple fan-shaped pieces;

[0008] Step 2: Place the multiple sector plates from Step 1 into a grooving machine to roll out grooves, and roll out two grooves on each sector plate, with the two grooves rolled on the two sides of the sector plate respectively.

[0009] Step 3: Place the multiple fan-shaped plates, after being rolled and grooved, into the embossing machine one by one to roll out the toothed grooves;

[0010] Step 4: Bend all the fan-shaped plates formed in Step 3 into arc shapes that fit the two ends of the cylinder body;

[0011] Step 5: Place the multiple fan-shaped plates, which have been bent and shaped in Step 4, into the punching machine one by one to make round holes;

[0012] Step Six: Assemble the multiple sector plates after drilling in Step Five into a bowl shape that fits the side of the cylinder body, so that each sector plate is sequentially inserted into the slot of an adjacent sector plate, and the round holes on the two adjacent sector plates are aligned.

[0013] Step 7: Use rivets to insert into the round holes to fix the positions of the multiple fan-shaped plates that are spliced ​​into a bowl shape. Use rivet pliers to press the rivets so that the rivets and fan-shaped plates do not separate.

[0014] Preferably, at least twenty sector-shaped panels are cut in step one.

[0015] Preferably, the two grooves rolled out in step two are straight grooves three centimeters from the edges of the fan-shaped plate.

[0016] Preferably, the grooves formed in step three are located on the same side of the two slots of the sector plate.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] In this solution, fan-shaped iron sheets are processed and then overlapped and fixed with rivets, which facilitates the formation of a bowl shape from multiple fan-shaped sheets. By pressing grooves and slots, the overlapping fan-shaped iron sheets are made to be on the same plane, which is more aesthetically pleasing and avoids the waste of materials by using connecting plates. At the same time, it also increases the contact area between adjacent fan-shaped iron sheets, making the connection between adjacent fan-shaped iron sheets tighter and more stable.

[0025] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0026] Please refer to the following: Figures 1 to 5 The method shown is a processing method for a sheet metal thermal insulation outer cladding panel, which includes the following steps:

[0027] Step 1: Cut the sheet metal into multiple fan-shaped pieces;

[0028] Step 2: Place the multiple sector plates from Step 1 into a grooving machine to roll out grooves, and roll out two grooves on each sector plate, with the two grooves rolled on the two sides of the sector plate respectively.

[0029] Step 3: Place the multiple fan-shaped plates, after being rolled and grooved, into the embossing machine one by one to roll out the toothed grooves;

[0030] Step 4: Bend all the fan-shaped plates formed in Step 3 into arc shapes that fit the two ends of the cylinder body;

[0031] Step 5: Place the multiple sector-shaped plates, which have been bent and shaped in Step 4, into the punching machine one by one to make round holes;

[0032] Step Six: Assemble the multiple sector plates after drilling in Step Five into a bowl shape that fits the side of the cylinder body, so that each sector plate is sequentially inserted into the slot of an adjacent sector plate, and the round holes on the two adjacent sector plates are aligned.

[0033] Step 7: Use rivets to insert into the round holes to fix the positions of the multiple fan-shaped plates that are spliced ​​into a bowl shape. Use rivet pliers to press the rivets so that the rivets and fan-shaped plates do not separate.

[0034] The number of sector-shaped panels cut in step one should be at least twenty;

[0035] The two grooves rolled out in step two are straight grooves three centimeters from the two edges of the fan-shaped plate;

[0036] The grooves formed in step three are located on the same side of the two slots in the sector plate.

[0037] The specific implementation method is as follows: When it is necessary to process sheet metal into an outer protective plate, the sheet metal is first cut into multiple fan-shaped pieces of the same size, which facilitates the subsequent splicing of multiple fan-shaped sheet metal pieces into a bowl shape. Then, a grooving machine is used to press two slots into each fan-shaped sheet metal piece. The two slots are respectively set on two sides of the fan-shaped sheet metal piece. Since the slots are rolled and shaped, the other side of each slot is rolled and raised. When it is necessary to splice the slotted fan-shaped sheet metal pieces, the raised slots are inserted into the recessed slots to achieve a temporary connection between the two fan-shaped sheet metal pieces. Then, a embossing machine is used to roll grooves into the fan-shaped sheet metal pieces. Rolling the grooves makes the fan-shaped sheet metal piece Z-shaped when viewed from the side, which facilitates the raised slots of adjacent sheet metal pieces to be inserted into the recessed slots. This ensures that when two fan-shaped sheet metal pieces are connected, they are on the same plane without unevenness. At the same time, the fan-shaped plate grooves... Instead of the existing connection method where the connecting plate overlaps one side of the adjacent fan-shaped iron sheet, the fan-shaped iron sheet is bent into an arc shape that fits the two ends of the cylinder body. After multiple fan-shaped iron sheets are spliced ​​together, the bent fan-shaped iron sheets are spliced ​​and fixed into a bowl shape by rivets through the round holes. The formed bowl-shaped outer protective plate is then placed on the outside of the cylinder body that is fixed with the heat insulation pad. Finally, the bowl-shaped outer protective plate and the cylinder body are connected and fixed by rivets. In this solution, the fan-shaped iron sheets are processed and shaped, and then the formed iron sheets are overlapped and fixed by rivets. This makes it easier for multiple fan-shaped iron sheets to form a bowl shape. By rolling grooves and slots, the two overlapping fan-shaped iron sheets are made to be on the same plane, which is more aesthetically pleasing and avoids the waste of materials by using connecting plates. At the same time, it also increases the contact area between adjacent fan-shaped iron sheets, thereby making the connection between adjacent fan-shaped iron sheets tighter and more stable.
