Description

Technical Field

[0002] Sheet metal parts are components made from metal sheets (such as steel, aluminum, copper, and stainless steel) through processes such as cutting, bending, stamping, and welding. They are widely used in the production of equipment housings, structural frames, and various mechanical components. The production and processing of industrial switches requires cutting, bending, stamping, and welding of sheet metal parts to create the housing.

[0003] When bending the chassis of traditional industrial switches, a dedicated bending machine is mostly used for manual bending. The metal sheet metal parts need to be manually held and placed on the bending parts of the bending machine for multiple bending.

[0014] A method for using a metal sheet metal processing device comprises the following steps:

[0015] Step 1: Clamp the metal sheet metal for the industrial switch chassis to be processed into the positioning angle for positioning. At this time, the outer folding part of the metal sheet metal corresponds to the outer folding groove, and the inner folding part of the metal sheet metal corresponds to the inner folding groove.

[0016] Subsequently, the first motor is controlled to start to drive the longitudinal shaft to rotate, thereby driving the driving disk to rotate, and cooperating with the plane thread convex movably clamped in the plane thread groove, driving the two first adjusting slides and the two second adjusting slides to slide synchronously backward, and then controlling the first pressing frames on both sides and the second pressing frames on both sides to move synchronously backward, so that the first pressing frames on both sides and the second pressing frames on both sides correspond to the outer folding grooves, and then, controlling the first telescopic cylinders on both sides to drive the first end pressing blocks on both sides to slide backward, and controlling the second telescopic cylinders on both sides to drive the second end pressing blocks on both sides to slide backward, so that the contact positions of the first end pressing blocks and the second end pressing blocks correspond to the positions of the corners of the outer folding parts of the metal sheet metal;

[0017] Subsequently, the plurality of lifting cylinders are controlled to be turned on to drive the pressing mechanism to lift and lower, so that the pressing mechanism presses the metal sheet metal part. Subsequently, the second motor is controlled to be turned on to drive the second conical teeth to drive the corresponding first conical teeth to rotate, and the plurality of first cams are synchronously driven to rotate in conjunction with the meshing connection of the adjacent first conical teeth and the transmission of the first pulley transmission group and the second pulley transmission group, thereby controlling the first outer folding plate and the second outer folding plate to move upward in the outer folding groove, and automatically folding the four sides of the pressed metal sheet metal part outward once.

[0018] The second step is to control the first and second end pressure blocks on both sides to slide toward each other, and the second and second end pressure blocks on both sides are driven to slide toward each other by controlling the opening of the first telescopic cylinders on both sides. The second telescopic cylinders on both sides are controlled to open and drive the second end pressure blocks on both sides to slide toward each other, and the first motor is controlled to open and drive the longitudinal axis to rotate in the opposite direction, thereby driving the driving plate to rotate in the opposite direction, and cooperate with the plane thread convex to movably engage in the plane thread groove, driving the two first adjusting slides and the two second adjusting slides to slide toward each other synchronously, and then controlling the first pressing frames on both sides and the second pressing frames on both sides to move toward each other synchronously, so that the first pressing frames on both sides and the second pressing frames on both sides correspond to the inner folding grooves, and the contact positions of the first end pressure blocks and the second end pressure blocks correspond to the positions of the corners of the inward folding part of the metal sheet metal.

[0019] Subsequently, the entire pressing mechanism is moved downward to press the metal sheet metal part again, and then the third motor is controlled to start, driving the fourth conical tooth to drive the corresponding third conical tooth to rotate, and the meshing connection of the adjacent third conical teeth and the transmission of the third pulley transmission group and the fourth pulley transmission group are coordinated to synchronously drive the multiple second cams to rotate, thereby controlling the first inner folding plate and the second inner folding plate to move upward in the inner folding groove, and automatically performing a second inner folding on the four sides of the pressed metal sheet metal part;

Then, the telescopic rod is controlled to drive the processing vertical frame and the welding head to move horizontally, and the linear electric rail is controlled to drive the welding head to move vertically. The welding head is moved to the welding position of the edge of the metal sheet metal and automatically welded using the welding head.

[0021] After welding is completed, the telescopic rod and the linear electric rail are controlled to drive the two grinding discs to move horizontally and vertically, and the two grinding discs are moved to the welding position of the metal sheet edge. The fourth motor is controlled to start, and the meshing connection of the fifth conical teeth is coordinated to drive the two grinding discs to rotate synchronously to automatically grind the welding position;

[0022] Step 4. After the metal sheet metal is folded, welded and polished, the first telescopic cylinders on both sides are controlled to open again to drive the first end pressure blocks on both sides to slide toward each other, the second telescopic cylinders on both sides are controlled to open to drive the second end pressure blocks on both sides to slide toward each other, and the first motor is controlled to control the driving longitudinal axis to rotate in the opposite direction, thereby driving the driving disk to rotate in the opposite direction, and cooperating with the flat thread cam to be movably engaged in the flat thread groove, driving the two first adjusting slides and the two second adjusting slides to slide toward each other synchronously, and then controlling the first pressure frames on both sides and the second pressure frames on both sides to move toward each other synchronously, and moving the entire top pressing mechanism upward to disengage.
