Embodiment 1

[0042] The square bushing processing method of the present embodiment, the steps are as follows:

[0043] 1. Folding: Select the iron sheet with a specified width, and then start from the front end of the iron sheet, along the length direction of the iron sheet, use the processing device to fold the edge at the same distance, the bending angle is 90°, repeat four times;

[0044] 2. Retain the edge: start from the fourth bend, and cut along the length direction of the iron sheet to the rear end of the iron sheet with a narrow edge of 3cm margin;

[0045] 3. Fixing: make holes on the narrow side, and make holes at the corresponding position of the first end of the iron sheet, and the fasteners pass through the openings of the narrow side and the first end of the iron sheet in turn to fix the narrow side and the first end of the iron sheet.

[0046] The existing directional sleeve adopts a welding process when connecting the iron sheet, which is easy to miss welding, time-consumi...

Embodiment 2

[0048] The square casing processing method of this embodiment is further improved on the basis of Embodiment 1, and the processing device described in step 1 includes:

[0049] A workbench 1 is composed of a horizontally arranged platform 10 and support legs 11 fixedly connected to the bottom of the platform 10;

[0050] Platen mechanism 2, which is arranged on the top surface of the front end of the platen 10, between the platen mechanism 2 and the top surface of the platen 10, there is an insertion seam 20 for the iron sheet to be processed to pass through;

[0051] The bent plate portion 3 is a flat plate and is arranged on the front end of the table 10 , and one end of the bent plate 3 is hinged to the front end of the table 10 .

[0052] Although the folding machine dedicated to the current market has high folding efficiency, the price is relatively high, and it is easy to damage the machine when folding the iron sheet above 1.6mm, while the manual processing is inefficie...

Embodiment 3

[0056] The square casing processing method of this embodiment is further improved on the basis of Embodiment 2. One end of the bent plate part 3 is hinged to the front end of the platen 10 through the hinge shaft 30, and the other end of the bent plate part 3 is hinged on both sides. An operating handle 31 is fixedly connected.

[0057] Such as figure 2 and image 3 As shown, the hinged shaft 30 includes shaft sleeves located at both ends and a shaft portion located in the middle, the shaft sleeves are fixedly welded on the front end surface of the platen 10, the two ends of the shaft are rotatably connected in the two shaft sleeves, and the bent plate portion 3 One end is fixedly welded to the rotating shaft, thereby forming the hinge between the bent plate portion 3 and the hinge shaft 30 .

[0058] Such as image 3 and Figure 4 As shown, two operating handles 31 are fixedly welded on both sides of the other end of the bending part 3, and the operator can drive the ben...

Abstract

The invention discloses a square sleeve machining method, and belongs to the technical field of iron sheet auxiliary machining. The method comprises the following steps that 1, edge folding, specifically, an iron sheet with the specified width is selected, then edge folding is conducted through a machining device from the front end of the iron sheet in the length direction of the iron sheet according to the same interval, the bending angle is 90 degrees, and the operation is repeated for four times; 2, edge reserving: starting from the fourth bending part, reserving a narrow edge with the edge distance of 3cm towards the rear end of the iron sheet in the length direction of the iron sheet, and then cutting; and 3, fixing: forming a hole in the narrow edge, forming a hole in the corresponding position of the head end of the iron sheet, and fixing the narrow edge and the head end of the iron sheet by a fastener sequentially penetrating through the hole in the narrow edge and the hole in the head end of the iron sheet. The method is easy to operate, fire welding is not needed in the sleeve machining process, a fastener connecting mode is adopted, and the connecting structure is more effective.

Description

technical field [0001] The invention belongs to the technical field of iron sheet auxiliary processing, and more specifically relates to a processing method for a square casing. Background technique [0002] Iron sheet casing is a commonly used structural part in building construction. Before the square casing is applied, the iron sheet needs to be bent according to the size requirements of the use environment. [0003] At present, square casings are usually processed by edge folding machines in the market, but the price of special edge folding machines in the market is high, and it can only bend iron sheets below 1.6mm, and the machine is easy to be damaged if it is higher than 1.6mm; After reaching a thickness of 1.6mm, manual knocking and bending are not easy to bend, the iron sheet material is sharp, construction personnel are easily injured, and the finished product has poor aesthetics. Cutting the iron sheet uses a welding process, which is easy to weld leakage, time-c...
