Description

Technical Field

[0001] The utility model relates to the field of sheet metal processing equipment, in particular to a sheet metal punching device. Background Art

[0002] Sheet metal is a comprehensive cold processing technology for thin metal plates (usually less than 6mm), including shearing, punching / cutting / combining, folding, welding, riveting, splicing, forming, etc. Its most notable feature is that the thickness of the same part is consistent, and the product processed by sheet metal technology is called sheet metal parts. The sheet metal parts referred to in different industries are generally different, and are mostly used as the name for assembly.

[0003] A sheet metal punching device is disclosed in a Chinese patent with the announcement number CN 220880610 U, which relates to the field of punching technology, including a bottom plate, a folding plate connected to one side of the top of the bottom plate by bolts, a placement block is arranged on the top of the bottom plate, and a clamping mechanism is arranged on the placement block, an adjustment mechanism is arranged below the top of the folding plate, and a punching mechanism is arranged below the adjustment mechanism. When punching holes in sheet metal parts of different sizes, the utility model drives the driven gears on the two slides through the operation of the driving motor, and then the forward and reverse rotation of the driving motor makes the two slides approach or move away from each other, so that the spacing between the two baffles becomes adjustable, and no manual adjustment is required throughout the process, thereby improving the efficiency of the punching operation.

[0004] The inventor has discovered that although the above technology can clamp the workpiece through the clamping mechanism, it is necessary to shut down the equipment and wait during the process of disassembling and assembling the workpiece to facilitate personnel to replace the workpiece, which is inefficient. At the same time, it cannot be used for workpieces that exceed the maximum clamping length of the clamping mechanism, resulting in certain limitations in use. Therefore, a sheet metal punching device is proposed based on this technology. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0029] The utility model provides a technical solution: Figure 1-Figure 4As shown, in this embodiment, a sheet metal punching device includes a frame 2, an electric telescopic rod 19, a vertical electric slide rail, a drill bit 20 and a transverse electric slide rail 21, the vertical electric slide rail is fixed to the upper end of the frame 2, the vertical electric slide rail is connected to the slider of the transverse electric slide rail 21, the electric telescopic rod 19 is fixed to the slider of the transverse electric and the vertical electric slide rail through a fixed plate, the drill bit 20 is fixed to the telescopic end of the electric telescopic rod 19, two groups of clamping structures are arranged at the lower end of the frame 2, and a support bar 8 is fixed on the frame 2 in the middle position of the two groups of clamping structures, and a protective component is arranged on the upper side of the frame 2.

[0030] like Figure 1 and Figure 4 As shown, the two groups of clamping structures include two groups of bidirectional screw rods 11 rotatably connected to the inside of the frame 2, and the ends of the bidirectional screw rods 11 are respectively provided with a first nut seat 12 and a second nut seat 13 through a ball nut pair. A slide groove is provided at the corresponding position of the lower end of the frame 2, and the bidirectional screw rod 11 is installed in the slide groove. The first nut seat 12 and the second nut seat 13 are slidably connected in the slide groove. Through the bidirectional screw rod 11, it is convenient to use the driving motor 5 to drive the first nut seat 12 and the second nut seat 13, thereby driving the first support rod 6 and the second support rod 9 to move. Through the slide groove, it is convenient to limit the first nut seat 12 and the second nut seat 13 so that they can move back and forth normally.

[0031] like Figure 1 and Figure 4 As shown, a first support rod 6 is fixed to the upper end of the first nut seat 12, a limiting frame 14 is fixed to the second nut seat 13, and a threaded hole is processed inside the limiting block 15, and the limiting block 15 is placed in the limiting frame 14. A second support rod 9 is fixed to the upper end of the limiting block 15, and the tops of the first support rod 6 and the second support rod 9 extend to the upper side of the slide groove, and a fixing bolt 10 passes through the inside of the second support rod 9, and the bottom of the fixing bolt 10 is screwed into the threaded hole through a thread. The first support rod 6 and the second support rod 9 are used to facilitate the installation of the positioning roller 3. Through the threaded hole and the fixing bolt 10, it is convenient to disassemble the corresponding positioning roller 3 when drilling a longer plate, avoiding the placement of the plate and improving the scope of application.

[0032] like Figure 1As shown, the top of the first support rod 6 and the second support rod 9 are both equipped with a rotating sleeve 7, and two groups of U-shaped frames 4 are fixed to the sides of the rotating sleeve 7 through fixed rods, and the angle between the two adjacent groups of U-shaped frames 4 is 90°, and the positioning roller 3 is rotatably connected inside the U-shaped frame 4, and two groups of drive motors 5 are fixed on the left and right sides of the frame 2. The output shaft of the drive motor 5 extends into the slide groove and is fixedly connected to the end of the bidirectional screw rod 11. Through the setting of the rotating sleeve 7, the positioning roller 3 can rotate around the first support rod 6 and the second support rod 9, so that the positioning roller 3 can support the plate, thereby making the drilling more stable.

[0033] like Figure 1 and Figure 2 As shown, the protection component includes a transparent protection cover 1 mounted on the outside of the frame 2, cylinders 16 are fixed on both sides of the upper end of the frame 2, the telescopic end of the upper side of the cylinder 16 is fixedly connected to the inner side of the protection cover 1, and the protection component also includes an exhaust pipe 17 fixed to the rear side of the frame 2, the front part of the exhaust pipe 17 extends to the inner side of the frame 2, and the middle position of the exhaust pipe 17 is connected to a duct for connecting to an exhaust fan.

When it is necessary to drill a longer plate, the personnel can unscrew the fixing bolt 10 on the second support rod 9, and the second support rod 9 can be taken out of the fixing frame for disassembly, so that the outermost four groups of positioning rollers 3 form a new clamping structure, which can clamp the long plate and is more flexible in use.

[0035] Although the embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
