Description

Technical Field

[0001] The invention relates to the technical field of sheet metal devices, in particular to a sheet metal device and a process method for manufacturing a cylinder. Background Art

[0002] Sheet metal processing is a comprehensive cold processing process for thin metal plates (usually less than 6mm). Generally, some thin metal plates are plastically deformed by hand or die stamping to form the desired shape and size, and can be further welded or processed in small amounts to form more complex parts. For example, chimneys, iron stoves, ventilation ducts, fuel tanks and oil pots commonly used in households are all sheet metal parts. In sheet metal processing, sheet metal bending is a very important process. It only requires two supports to support the two sides of the position where the sheet metal needs to be bent, and then the sheet metal is stamped downward to press the upper surface of the sheet metal so that the position where the sheet metal is pressed is moved downward to achieve bending. In order to meet the needs of production delivery, in many cases, the sheet metal needs to be rolled into a cylindrical shape. Through a universal device for bending metal sheets into a cylinder, according to the principle of three points forming a circle, the relative position change and rotational motion of the workpiece are used to make the sheet metal produce continuous plastic deformation to obtain a workpiece of a predetermined shape.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] 1. The present invention, through the arrangement of the second motor and the hand wheel, enables the upper pressure roller to move electrically or manually. The threaded rod is rotated to drive the two threaded blocks to move horizontally on the threaded rod, and the distance between the two upper pressure rollers is adjusted, which is convenient for guiding and rolling plates of different sizes. The arrangement of the two upper pressure rollers improves the flexibility and working efficiency of the sheet metal device. The hydraulic cylinder is arranged to drive the hydraulic rod to lift the upper pressure roller, which is convenient for adjusting the distance between the upper pressure roller and the lower rolling roller.

[0025] 2. By setting a pressure plate between the pressure roller frame and the hydraulic cylinder, the elastic mechanism set inside the pressure plate plays a buffering role, which can avoid the impact force brought by the upper pressure roller during pressing. Through the cooperation between the positioning rod and the positioning sleeve, the pressure plate plays a positioning role in the pressing process, thereby improving the stability of the pressure plate.

[0026] 3. The guide seat is driven to move by an electric push rod, so that the guide seat can move in the guide groove, playing a guiding role. By starting the first motor, the output end of the first motor drives the driving wheel to rotate, so that the driving wheel is connected to the synchronous wheel through a chain transmission, thereby driving the two lower winding rollers to rotate. The chain transmission method makes the average transmission ratio of the two lower winding rollers accurate when they rotate, and the operation is reliable and efficient.

[0027] 4. By arranging rollers on the lower surface of the first mounting frame, the rollers are slidably connected to the slide rails. When the guide seat moves, the second mounting frame is also driven to move, so that the two lower rollers drive the first mounting frame to move in the slider seat. The cooperation between the rollers and the slide rails facilitates smoother movement of the first mounting frame. The sliding cooperation between the slider seat and the slide groove seat facilitates the disassembly and assembly of the lower rollers.

[0028] 5. By setting a collection box under the workbench to place raw materials or finished products in it, it is convenient to take and put materials. By setting the fixed block, it plays a supporting role for the moving plate. BRIEF DESCRIPTION OF THE DRAWINGS
