[0002] Military electronic enclosures are widely used in military instruments, meters, electronics, communications, automation, and precision machinery. Their structure consists of an aluminum alloy frame, ABS, MDF, plywood, metal plates, etc. for the front panel, and T-joints, door strips, handles, locks, etc. as accessories.

[0003] In the production process of electronic chassis, sheet metal is used as the raw material. However, the purchased sheet metal is often too large to be directly stamped. It needs to be cut into the required sizes before stamping and other operations. In practice, to meet production needs, a large number of sheets often need to be cut, thus requiring the use of sheet metal cutting machines.

[0004] While traditional sheet metal cutting machines can shorten product production cycles, they have certain drawbacks: First, existing sheet metal cutting machines require manual loading, resulting in slow loading speeds. Furthermore, the machine must be stopped after cutting before unloading finished products, otherwise it will affect the cutting of other sheet metal parts on the worktable. This prevents continuous loading and unloading without stopping the machine, reducing processing efficiency. Additionally, the shavings generated during cutting can contaminate the material, affecting subsequent material processing. Therefore, there is an urgent need to design a sheet metal cutting device for chassis production. Utility Model Content

This invention can automatically perform loading and unloading operations during the cutting process, improving work efficiency, and can also perform dust extraction during cutting to prevent waste chips from splashing onto the material and contaminating it.

[0006] The technical solution adopted by this utility model to solve the technical problems existing in the prior art is as follows: A sheet metal cutting device for chassis production includes a frame, an operating table installed on the top of the frame, a processing pad installed in the operating area of ​​the operating table, and a cutting groove formed on the processing pad; a liftable and movable pressure plate protective assembly is provided above the cutting groove for covering the cutting groove and pressing the workpiece; it also includes a cutting assembly installed on the frame, the upper part of which penetrates the cutting groove for cutting the workpiece pressed by the pressure plate protective assembly; it also includes a dust collection hood installed below the operating table, covering the cutting assembly and the cutting groove, the dust collection hood being connected to a suction fan through a gas pipeline; and an upstream device of the pressure plate protective assembly is installed on the frame. The feeding assembly is used to convey material between the pressure plate protection assembly and the cutting groove; a pushing assembly is provided downstream of the pressure plate protection assembly to push the workpiece after the cutting operation, and also includes a discharge guide assembly located at the discharge end of the pushing assembly and mounted on the frame to guide the workpiece pushed by the pushing assembly; the pressure plate protection assembly includes a dust collection protective cover located directly above the cutting groove, and pressure plates located on both sides of the cutting groove are installed on the bottom edge of the dust collection protective cover, and also includes a lifting cylinder for driving the dust collection protective cover to move up and down; the pushing assembly includes a pushing plate that is adjacent to the top surface of the processing pad and has a clearance fit with it, and also includes a pushing drive mechanism for driving the pushing plate to move laterally; the movement of the pushing plate is consistent with the extension direction of the cutting groove.

Through the feeding component, it can automatically convey the sheet metal forward, achieving automatic feeding without manual operation, thus improving the working efficiency of the cutting device. By setting up the cutting component, in conjunction with the cutting grooves on the processing pad, it can perform cutting operations on the sheet metal. By setting up the pressure plate protection component, it can press and position the cut sheet metal, preventing displacement or even flying out during cutting, thus improving the cutting accuracy and safety of the cutting device. By setting up a dust collection hood connected to the suction fan, in conjunction with the dust collection protective hood in the pressure plate protection component, a concentrated space can be formed in the cutting area during the cutting process, thereby collecting the waste dust and smoke generated during the cutting operation and preventing waste dust from splashing onto the sheet metal and causing pollution.

Length graduations are provided on the discharge adjusting plate 7-3 along the extension direction of the discharge adjusting groove 7-5.

[0038] In actual operation, this utility model can be used in conjunction with a linear conveyor, that is, the feeding assembly 11 is connected to the conveyor for inputting the plate, and the discharge guide assembly 7 is connected to the output device for outputting the workpiece; of course, a workbench can also be used to replace the above-mentioned conveyor and output device. In this case, the operator needs to push the plate between the feeding drive roller 11-10 and the feeding driven roller 11-2 in the feeding assembly 11.

[0039] Working principle:

[0040] In actual operation, the positions of the two sets of feeding adjustment blocks 11-4 in the feeding assembly 11 are adjusted according to the size of the plate to be cut and the cutting requirements, and the positions of the two sets of discharge adjustment blocks 7-4 in the discharge guide assembly 7 are adjusted according to the size of the cut workpiece.

[0041] The conveying device connected to the feeding assembly 11 pushes the plate into the feeding active roller 11-10 and the feeding driven roller 11-2 in the feeding assembly 11. The rotating feeding active roller 11-10 and the feeding driven roller 11-2 convey the plate forward. The plate passes through the sleeves installed on the two sets of feeding adjustment blocks 11-4, thereby realizing the limiting feeding operation of the plate without the need for manual feeding operation.

[0042] After the plate is transported forward a preset distance, the lifting cylinder 8-3 in the pressure plate protection assembly 8 is activated, driving the dust collection protective cover 8-5 to move downward, thereby covering the cutting groove 10 and pressing the plate onto the processing pad 9 to fix the plate in place and prevent the plate from moving during cutting, thus avoiding cutting errors. Then, the lead screw motor 13-1 and the circular saw motor 13-4 in the cutting assembly 13 are activated, driving the rotating circular saw 13-7 to penetrate the cutting groove 10 and move laterally, thereby performing the cutting operation on the plate. During the operation, the suction fan is started to collect the waste chips and dust generated during the cutting operation, preventing waste chips from splashing onto the plate and causing pollution.

[0043] During the cutting operation, the pusher cylinder 5-1 in the pusher assembly 5 is periodically activated, driving the pusher transverse seat 5-5 to move back and forth periodically along the pusher guide rail 5-2, thereby pushing the workpiece that has completed the cutting operation toward the discharge guide assembly 7. Under the guiding transition of the discharge guide assembly 7, the plate is pushed out of the operating area of ​​the processing pad 9, and the finished product unloading operation can be realized without stopping the machine, which improves the working efficiency of the cutting device.
