Description

Technical Field

[0001] This utility model relates to the field of sheet metal cutting technology, and in particular to a sheet metal cutting machine for automotive parts production. Background Technology

[0002] Laser cutting machines are one of the core pieces of equipment in the production of automotive parts, used for processing various materials and components. Traditional laser cutting equipment often uses a fixed dust extraction port at the bottom. However, when cutting automotive parts, due to the complex shapes of these parts, it's impossible to track the moving cutting point in real time. This results in significant escape of metal dust and harmful gases generated during cutting, polluting the working environment and endangering the health of operators. To address these shortcomings, we propose a new sheet metal cutting machine for automotive parts production. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a sheet metal cutting machine for automotive parts production.

[0004] To address the problems existing in the prior art, the present invention adopts the following technical solution: a sheet metal cutting machine for automotive parts production, comprising a laser cutting machine, wherein the laser cutting machine comprises a laser cutting machine base, a sheet metal placement platform fixedly installed on the inner wall of the laser cutting machine base, a gantry frame slidably fitted on the upper surface of the laser cutting machine base, and a laser cutting head disposed on the surface of the gantry frame; wherein: a floating dust collection mechanism is provided on the surface of the laser cutting machine base, and a top dust collection mechanism is provided above the gantry frame;

[0005] The floating vacuuming mechanism includes track grooves on the front and back of the laser cutting machine base, a U-shaped movable frame that slides on the inner wall of the track groove, a bottom vacuum hood that is fixedly installed on the inner wall of the U-shaped movable frame, and a vacuuming pipe assembly that communicates with the bottom vacuum hood.

[0009] Preferably, the dust cover is made of flame-retardant fabric.

[0010] Preferably, both the top suction pipe and the spark catcher are connected to an external belt dust collector.

[0011] Preferably, the left side of the U-shaped movable frame is fixedly connected to the right side of the gantry frame.

[0012] Preferably, the gantry frame is located inside a dustproof cloth cover.

[0013] Preferably, one end of the bottom suction pipe extends into the interior of the bottom suction hood, and the width of the bottom suction hood is 20-30 cm greater than the board placement platform.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The U-shaped movable frame is rigidly connected to the gantry frame, allowing the bottom dust hood to move synchronously with the gantry frame, ensuring that the dust collection area always covers the vertical projection range of the cutting point, thus solving the problem of displacement deviation of the traditional fixed dust collection port.

[0016] 2.

Detailed Implementation

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figure 1-4 This utility model provides a technical solution: a sheet metal cutting machine for automotive parts production, including a laser cutting machine, the laser cutting machine including a laser cutting machine base 10, a sheet metal placement platform 11 fixedly installed on the inner wall of the laser cutting machine base 10, a gantry frame 12 slidably fitted on the upper surface of the laser cutting machine base 10, and a laser cutting head 13 disposed on the surface of the gantry frame 12.

[0025] The material to be processed is placed on the material placement platform 11, which is fixed to the inner wall of the laser cutting machine base 10. The gantry 12 slides on the upper surface of the laser cutting machine base 10. The movement trajectory of the gantry 12 is precisely controlled by the control unit inside the laser cutting machine, thereby driving the laser cutting head 13 on its surface to position the cutting point in three-dimensional space. The laser cutting head 13 emits a high-energy laser beam that is focused on the surface of the material to achieve precise cutting. This technology is well-known in laser cutting machines, so it will not be described in detail.

[0026] A floating dust collection mechanism is provided on the surface of the laser cutting machine base 10. The floating dust collection mechanism includes track grooves on the front and back of the laser cutting machine base 10, a U-shaped movable frame 20 that slides on the inner wall of the track groove, a bottom dust collection hood 21 that is fixedly installed on the inner wall of the U-shaped movable frame 20, and a dust collection pipe assembly that communicates with the bottom dust collection hood 21. The width of the bottom dust collection hood 21 is 20-30 cm wider than the width of the board placement table 11. The left side of the U-shaped movable frame 20 is fixedly connected to the right side of the gantry frame 12. The U-shaped movable frame 20 is rigidly connected to the gantry frame 12, so that the bottom dust collection hood 21 can move synchronously with the gantry frame 12 to ensure that the dust collection area always covers the vertical projection range of the cutting point. The bottom dust collection hood 21 is 20-30 cm wider than the board placement table 11 to further expand the dust capture range.

[0027] The dust collection pipe assembly includes a bottom dust collection pipe 22 fixedly installed on the surface of the bottom dust collection hood 21, and a spark catcher 23 connected to the bottom dust collection pipe 22. The surface of the U-shaped movable frame 20 has a through hole for the bottom dust collection pipe 22 to pass through. The bottom dust collection hood 21 is located below the board placement platform 11, and the bottom dust collection hood 21 is perpendicularly projected to the laser cutting head 13. One end of the bottom dust collection pipe 22 extends into the interior of the bottom dust collection hood 21. The bottom dust collection hood 21 is connected to an external dust removal system through the bottom dust collection pipe 22, forming a stable negative pressure airflow in the cutting area to efficiently suck up the metal dust and harmful gases generated under the board during cutting. At the same time, the integrated spark catcher 23 can intercept the sparks and high-temperature particles generated during cutting in real time, reducing the risk of fire.

[0028] A top dust collection mechanism is provided above the gantry frame 12. The top dust collection mechanism includes a top dust collection cover 31 fixedly installed on the upper surface of the gantry frame 12 via a support frame 30, a dust cover 32 fixedly installed on the lower surface of the top dust collection cover 31, and a top dust collection pipe 33 fixedly installed on the front of the top dust collection cover 31. The gantry frame 12 is located inside the dust cover 32. The dust cover 32 is made of flame-retardant fabric to form a flexible protective space, which completely wraps the gantry frame 12 and the cutting area, effectively blocking the dust diffusion path and suppressing sparks.

[0029] The top suction pipe 33 and the top suction hood 31 are internally connected. The dust cover 32 is made of flame-retardant fabric. Both the top suction pipe 33 and the spark catcher 23 are connected to the external cloth bag dust collector. Both the top suction pipe 33 and the bottom suction pipe 22 are corrugated pipes. The corrugated design of the top suction pipe 33 and the bottom suction pipe 22 can freely extend and retract with the movement of the gantry frame 12 to maintain the continuity of the airflow channel. The top suction hood 31 generates negative pressure through the external cloth bag dust collector, which can quickly remove the metal dust generated by cutting above the plate.

[0030] Specifically, the working principle and operation method of this utility model are as follows:

[0031] Place the sheet material to be processed on the sheet material placement platform 11, start the laser cutting machine control system, automatically calibrate the cutting origin, and simultaneously activate the external bag dust collector to establish a negative pressure airflow between the bottom suction pipe 22 and the top suction pipe 33. When the laser cutting head 13 moves and cuts along the preset trajectory, the U-shaped movable frame 20 drives the bottom suction hood 21 to track in real time through the gantry frame 12, capturing the dust below. The top suction hood 31 forms a protective space through the dust cover 32, sucking up the particles that escape from above. The corrugated suction pipe adapts to the displacement of the gantry frame 12, and the spark catcher 23 intercepts high-temperature particles in real time. The dust cover 32 suppresses spark splashing. After the cutting is completed, reset the gantry frame 12 to the standby position.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art based on the technical solution and concept of the present utility model should be included within the protection scope of the present utility model.
