A slag-resistant laser cutting device

Abstract

This utility model discloses a slag-resistant laser cutting device. The device has multiple laser cutting heads mounted on the top of the laser cutting machine, each head equipped with a slag-splash-proof component on its outer ring. This component is secured to the outer ring of the head by clamps and connected to a corrugated pipe via a top plate. The corrugated pipe covers the head and has ventilation holes on its outer ring to facilitate the escape of cutting fumes. The bottom of the corrugated pipe has a bottom ring with protrusions on its outer surface. These protrusions are embedded in recesses containing ball bearings that contact the surface of the workpiece. The bottom ring, recesses, and ball bearings act as counterweights to maintain the tension of the corrugated pipe, and there is a suitable distance between the bottom of the bottom ring and the workpiece. This design effectively protects the slag generated during cutting, preventing it from splashing onto other parts of the workpiece and cutting machine components, ensuring a clean and safe cutting process, improving cutting quality and efficiency, reducing slag cleaning work, lowering the probability of equipment damage, and extending the equipment's service life.

Description

Technical Field

[0001] This utility model relates to the field of laser cutting machine technology, specifically to a laser cutting device with slag-resistant properties. Background Technology

[0002] In traditional laser cutting processes, laser cutting machines are widely used in metal processing, automotive manufacturing, aerospace, and many other fields due to their high precision and efficiency. However, a prominent problem exists in actual laser cutting operations: slag sputtering. When a laser beam acts on the workpiece to be cut, the high temperature causes localized rapid melting or even vaporization of the workpiece, resulting in slag. Under the powerful force generated by laser cutting, this slag sputters outwards at high speed.

[0003] On the one hand, sputtered slag will adhere to the surface of the workpiece, whether it has been cut or not, resulting in a decline in the surface quality of the workpiece. This requires a lot of manpower and time to clean up, which increases production costs and production cycle.

[0004] On the other hand, molten slag may also sputter onto other parts of the laser cutting machine, such as guide rails and lenses. For guide rails, the adhesion of molten slag will affect the smoothness of their movement, leading to a reduction in cutting accuracy; while for lenses, molten slag may cause scratches or contamination, affecting the transmission and focusing effect of the laser, and in severe cases, even requiring lens replacement, further increasing the maintenance cost of the equipment.

[0005] Furthermore, existing laser cutting equipment lacks effective protective measures against molten slag sputtering. While some devices attempt to employ simple shielding structures, these structures often suffer from poor flexibility and limited protection range. They cannot adjust the protection status in real time according to the movement of the cutting position, nor can they adequately adapt to the cutting needs of workpieces of different shapes and sizes. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of existing technologies by providing an anti-slag laser cutting device to solve the problems mentioned in the background art.

[0007] To achieve this objective, the present invention adopts the following technical solution: A slag-resistant laser cutting device includes a laser cutting machine, the top of which is provided with several laser cutting ends, and the outer surface of each laser cutting end is provided with a slag-resistant anti-splatter component. The slag anti-splash assembly includes a clamp locked to the outer surface of the laser cutting tip, a top plate fixed to the outer surface of the clamp, and a corrugated pipe fixedly connected to the bottom surface of the top plate and covering the laser cutting tip. The bottom end face of the corrugated pipe is fixed with a bottom ring, and the outer surface of the bottom ring is fixedly connected with four protrusions in a ring array. Each protrusion has a ball socket embedded in its interior, and each ball socket has a rolling ball embedded in its interior. The outer surface of the corrugated pipe has multiple vent holes in a ring array for the exhaust of fumes during the laser cutting process.

[0008] As a preferred embodiment of the anti-slag laser cutting device, the top plate has a circular hole inside for the clamp to be inserted, and the inside of the circular hole is filled with a fluororubber sealing ring.

[0009] As a preferred embodiment of the anti-slag laser cutting device, the outer ring of the corrugated tube is provided with multiple corrugated lines for folding up and down.

[0010] As a preferred embodiment of the anti-slag laser cutting device, the protrusions are provided with openings for ball sockets to be inserted.

[0011] As a preferred embodiment of the anti-slag laser cutting device, the bottom of each ball socket is provided with a groove for the rolling ball to roll and be embedded.

[0012] As a preferred embodiment of the anti-slag laser cutting device, the bottom end of the rolling ball is in contact with the surface of the workpiece to be cut.

[0013] As a preferred embodiment of the anti-slag laser cutting device, the bottom ring, the ball socket, and the rolling ball all serve as counterweights to keep the corrugated tube in a stretched state. The bottom surface of the bottom ring has a gap of 0.3cm-0.6cm with the workpiece, which is used to cover the slag during the cutting process with the corrugated tube and prevent the slag from splashing onto the rest of the workpiece surface and the rest of the cutting machine.

[0014] Compared with the prior art, the present invention has the following beneficial effects: This invention adds a slag anti-splatter component to a laser cutting machine. The component is secured to the laser cutting end with a clamp, and the top plate and corrugated pipe cover the end, effectively blocking molten slag generated during cutting and preventing it from splashing onto the rest of the workpiece surface and other parts of the cutting machine, thus protecting the workpiece and equipment. Ventilation holes on the outer ring of the corrugated pipe allow cutting fumes to escape, maintaining a stable internal environment. The bottom ring, ball socket, and rolling ball act as counterweights to keep the corrugated pipe in a stretched state. The rolling ball contacts the workpiece surface and can roll, facilitating the movement of the corrugated pipe during cutting. The bottom ring maintains a suitable distance from the workpiece, ensuring that the slag is covered without affecting the cutting operation. The overall structure makes the cutting process cleaner and safer, reduces slag cleaning work, improves cutting quality and efficiency, reduces the risk of equipment damage due to slag, and extends the equipment's service life.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0024] As shown in the figure, this embodiment provides a slag-resistant laser cutting device, including a laser cutting machine 1. The top of the laser cutting machine 1 is provided with four laser cutting ends 2. The specific number of laser cutting ends 2 can be adjusted according to the requirements. Each laser cutting end 2 is provided with a slag anti-splatter component 3 on its outer ring surface.

[0025] Among them, the clamp 3-1 of the slag anti-splash component 3 is locked to the outer ring surface of the laser cutting end 2, and the top plate 3-8 is fixed to the outer ring surface of the clamp 3-1. The top plate 3-8 has a round hole for the clamp 3-1 to be embedded in, and the round hole is filled with a fluororubber sealing ring to enhance the sealing performance.

[0026] The corrugated pipe 3-7 is fixedly connected to the bottom surface of the top plate 3-8 and covers the laser-cut end 2. Its outer ring has multiple corrugated patterns for folding up and down, and the outer ring surface has multiple ventilation holes 3-2 in a ring array.

[0027] A bottom ring 3-6 is fixed to the bottom end face of the corrugated pipe 3-7. Four protrusions 3-5 are fixedly connected in a ring array on the outer surface of the bottom ring 3-6. An opening is opened inside the protrusion 3-5 for the ball socket 3-3 to be inserted. The ball socket 3-3 is inserted into the opening. A groove is provided at the bottom of the ball socket 3-3 for the rolling ball 3-4 to roll and be inserted. The rolling ball 3-4 is inserted into the groove and its bottom end is in contact with the surface of the workpiece to be cut.

[0028] The bottom ring 3-6, the ball socket 3-3, and the rolling ball 3-4 act as counterweights to keep the bellows 3-7 in a stretched state. There is a 0.4cm gap between the bottom surface of the bottom ring 3-6 and the workpiece. During cutting, the molten slag is covered by the bellows 3-7 to prevent it from splashing onto the rest of the workpiece surface and the rest of the cutting machine. Example

[0029] This embodiment provides a slag-resistant laser cutting device, which is basically the same as the first embodiment. The main difference is the number of laser cutting ends 2 and the distance between the bottom of the bottom ring 3-6 and the workpiece.

[0030] Specifically, the laser cutting machine 1 has two laser cutting heads 2 on its top, and each laser cutting head 2 has a slag anti-spatter component 3 on its outer surface. In the slag anti-spatter component 3, a clamp 3-1 is locked to the outer ring of the laser cutting head 2, and a top plate 3-8 is fixed to the outer ring of the clamp 3-1. The round hole of the top plate 3-8 is filled with a fluororubber sealing ring. A corrugated pipe 3-7 is connected to the bottom of the top plate 3-8 and covers the laser cutting head 2. Its outer ring has corrugated patterns and vent holes 3-2. A bottom ring 3-6 is fixed to the bottom of the corrugated pipe 3-7. Its outer surface has four protrusions 3-5, and ball sockets 3-3 are embedded in the protrusions 3-5. A ball 3-4 is located in the groove at the bottom of the ball socket 3-3, and the bottom end of the ball 3-4 contacts the workpiece to be cut. The bottom ring 3-6, the ball socket 3-3, and the rolling ball 3-4 act as counterweights to stretch the bellows 3-7. The bottom of the bottom ring 3-6 is 0.3cm away from the workpiece, and the molten slag is covered by the bellows 3-7 during cutting. Example

[0031] This embodiment provides a slag-resistant laser cutting device, which is basically the same as the first embodiment. The main difference is the number of laser cutting ends 2 and the distance between the bottom of the bottom ring 3-6 and the workpiece.

[0032] Specifically, the laser cutting machine 1 has six laser cutting ends 2 on its top, and each laser cutting end 2 has a slag anti-splatter component 3 on its outer surface. Inside the slag anti-splatter component 3, a clamp 3-1 locks the outer ring of the laser cutting end 2, and a top plate 3-8 is fixed to the outer ring of the clamp 3-1. A fluororubber sealing ring is filled into the round hole. A bellows 3-7 connects to the bottom of the top plate 3-8 and covers the end, featuring corrugated patterns and ventilation holes 3-2. A bottom ring 3-6 is located at the bottom of the bellows 3-7, with four protrusions 3-5 on its outer surface inlaid with ball sockets 3-3. A ball 3-4 is located in the groove at the bottom of the ball socket 3-3, and the bottom end of the ball 3-4 contacts the workpiece. The bottom ring 3-6, ball sockets 3-3, and ball 3-4 act as counterweights to stretch the bellows 3-7. The distance between the bottom of the bottom ring 3-6 and the workpiece is 0.6 cm, ensuring that the slag is contained within the bellows 3-7 during cutting. Based on the above, the workflow of this technical solution is explained as follows: Place the workpiece to be cut in a suitable position and start the laser cutting machine 1. At this time, several laser cutting heads 2 set on the top of the laser cutting machine 1 start working and emit lasers to cut the workpiece.

[0033] During the laser cutting process, the slag anti-splatter component 3 plays a role. The clamp 3-1, which is locked on the outer surface of the laser cutting end 2, plays a fixing role, which stabilizes the entire slag anti-splatter component 3 on the laser cutting end 2. The top plate 3-8, which is fixed on the outer surface of the clamp 3-1, serves as a connecting component. The corrugated pipe 3-7, which is fixedly connected to the bottom surface, covers the laser cutting end 2. The outer ring of the corrugated pipe 3-7 is provided with multiple corrugated patterns that allow it to fold up and down, so that it can be flexibly extended and retracted. Multiple ventilation holes 3-2, which are arranged in a ring array on the outer surface, allow the fumes generated during the laser cutting process to escape. The bottom ring 3-6 fixed to the bottom end face of the bellows 3-7 serves as a support and connection. The outer surface of the bottom ring 3-6 has four protrusions 3-5 fixedly connected in a ring array. The protrusions 3-5 have openings inside for the ball sockets 3-3 to be inserted. The ball sockets 3-3 are inserted into the openings. The bottom of the ball sockets 3-3 has grooves for the rolling balls 3-4 to be inserted, so that the rolling balls 3-4 can be inserted and the bottom end contacts the surface of the workpiece to be cut. As the laser cutting end 2 moves, the rolling balls 3-4 roll on the surface of the workpiece, assisting the movement of the bellows 3-7.

[0034] Among them, the bottom ring 3-6, the ball socket 3-3, and the rolling ball 3-4 all act as counterweights to keep the bellows 3-7 in a stretched state. The bottom surface of the bottom ring 3-6 has a gap of 0.3cm to 0.6cm between it and the workpiece. During the cutting process, the generated slag is covered by the bellows 3-7 to prevent the slag from splashing onto the other surfaces of the workpiece and the other parts of the cutting machine. After the cutting is completed, the laser cutting machine 1 is turned off to complete the entire cutting process.

[0035] It should be stated that the above-described specific embodiments are merely preferred embodiments of this utility model and the technical principles employed. Those skilled in the art should understand that various modifications, equivalent substitutions, and variations can be made to this utility model. However, such variations, as long as they do not depart from the spirit of this utility model, should be within the protection scope of this utility model. Furthermore, some terminology used in this application specification and claims is not limiting, but merely for ease of description.
