Description

Technical Field

[0001] This utility model belongs to the field of laser cutting machine technology, specifically relating to a bed protection structure suitable for high-power laser cutting. Background Technology

[0002] In high-power laser cutting equipment, traditional machine beds generally employ a frame structure with a central crossbeam to enhance rigidity. However, after the high-power laser beam cuts through the workpiece, it can directly irradiate the crossbeam, causing it to burn and deform, thus affecting the lifespan of the machine bed. To protect against the laser, current technology typically lines the machine bed and the waste trolley below with refractory bricks. However, the refractory bricks are extremely heavy, significantly increasing the pushing and pulling resistance of the trolley and the operational burden. At the same time, they severely encroach on the effective material storage space of the waste trolley, leading to frequent cleaning and increasing the workload.

[0003] Furthermore, refractory bricks are prone to cracking under prolonged high-temperature impact, and the resulting fragments are difficult to clean, leading to high replacement and maintenance costs. Although there have been attempts to use metal protective plates, the flat layout easily creates gaps in the protection, allowing lasers to still penetrate and damage the underlying structure, resulting in incomplete protection. Therefore, existing solutions have significant shortcomings in terms of bed protection, lightweight operation, and ease of maintenance, urgently requiring an integrated solution that balances rigidity, lightweight design, and efficient protection. Utility Model Content

[0004] The purpose of this invention is to provide a bed protection structure suitable for high-power laser cutting, so as to solve the problems existing in the background art.

[0005] A bed protection structure suitable for high-power laser cutting, characterized in that it comprises: The main body of the bed adopts a hollow frame structure. The main body of the bed is composed of at least two parallel first longitudinal main beams and second longitudinal main beams, as well as a first transverse support and a second transverse support connected between the bottom of the first longitudinal main beams and the second longitudinal main beams. There are no intermediate transverse beams in the cutting operation area of ​​the main body of the bed. At least one waste trolley is disposed below the hollow space of the main body of the bed, and the waste trolley is an open box-type body; At least one funnel mechanism is disposed above the waste trolley and fixedly connected to the bed body, for guiding waste into the waste trolley; At least one protective component is fixed above the funnel mechanism. The protective component includes multiple L-shaped protective steel plates extending longitudinally along the bed. The multiple L-shaped protective steel plates are arranged alternately laterally along the bed and are divided into upper protective steel plates and lower protective steel plates. The openings of the L-shaped protective steel plates face downwards. When viewed from directly above, the upper and lower protective steel plates completely cover the waste trolley below them.

[0006] Preferably, the waste trolley includes a trolley body, a plurality of universal rollers disposed at the bottom of the trolley body, a push-pull handle disposed on the trolley body, and a guide mechanism fixed to the bottom of the bed body and cooperating with the universal rollers.

[0007] Preferably, the funnel mechanism includes a longitudinal guide plate arranged inclined along the longitudinal direction of the bed, a transverse guide plate arranged inclined along the transverse direction of the bed, and a first partition and a second partition disposed between adjacent funnel mechanisms.

[0008] Preferably, the protective assembly further includes two first end plates and a second end plate arranged laterally opposite each other along the bed, and a plurality of support beams fixed between the first end plates and the second end plates. The first end plate is fixedly connected to the first partition, the second end plate is fixedly connected to the second partition, and the longitudinal ends of the L-shaped protective steel plate are supported on the support beams.

[0009] Preferably, each of the L-shaped protective steel plates located in the lower layer is positioned between two adjacent L-shaped protective steel plates in the upper layer when viewed from above.

[0010] Preferably, there are multiple waste carts arranged laterally along the bed to collectively cover the entire cutting area of ​​the bed body; the number of the funnel mechanism and the protective components are the same as the number of waste carts and are arranged in a one-to-one correspondence.

[0011] The beneficial effects of this utility model are as follows: By adopting a hollow bed structure without a middle crossbeam, this utility model fundamentally avoids direct irradiation of the bed by high-power lasers, significantly extending the service life of the equipment; at the same time, by replacing traditional refractory bricks with double-layered alternating L-shaped protective steel plates, the weight of the waste trolley is reduced by more than 35%, and the effective volume is increased by more than 21%, greatly improving the ease of operation and waste collection efficiency; in addition, the coordinated design of the funnel mechanism and protective components not only realizes the guided collection of waste and zoned dust removal, but also ensures laser protection without blind spots, and the steel plates are easy to disassemble and replace, resulting in a significantly lower overall maintenance cost than the traditional refractory brick solution.

Those skilled in the art can understand the specific meaning of the above terms in this disclosure according to the specific circumstances.

[0016] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings and preferred embodiments.

[0017] like Figure 1-5 As shown in the attached drawings, this utility model provides a bed protection structure suitable for high-power laser cutting, aiming to solve the problems of easy bed damage, bulky waste carriage, small effective volume, and inconvenient maintenance in traditional solutions. Referring to the attached drawings, the structure mainly includes a bed body 1, a waste carriage 2, a funnel mechanism 3, and protective components 4.

[0018] The bed body 1 constitutes the main support frame of the equipment. It adopts a hollow frame design, consisting of two parallel and longitudinally extending first longitudinal main beams 11 and 12, and first and second transverse support members 13 and 14 connected at their bottoms by welding or bolting. Crucially, no intermediate crossbeams are installed inside the bed body 1 below the entire laser cutting work area, thus forming a continuous hollow space. This fundamentally eliminates the risk of the high-power laser beam burning the bed structure after cutting through the workpiece.

[0019] At least one scrap trolley 2 is slidably positioned directly beneath the aforementioned hollow space. Each scrap trolley 2 is typically a rectangular box structure with an open top, consisting of a trolley body 21, four omnidirectional casters 22 mounted on its bottom, and a push-pull handle 23 fixed to the side. A guide mechanism 24 (such as a guide rail) is fixedly installed at the bottom of the bed body 1. The omnidirectional casters 22 cooperate with the guide mechanism 24, allowing the scrap trolley 2 to be easily pulled out or pushed in along a predetermined track. To cover wide-area cutting needs, a single machine is typically equipped with multiple scrap trolleys 2, which are arranged side-by-side laterally along the bed.

[0020] Above the waste cart 2, a funnel mechanism 3 is fixedly installed. This funnel mechanism 3 is fixedly connected to the bed body 1. Its functions are twofold: first, to receive and guide the cutting waste to fall precisely into the waste cart 2 below; and second, to act as a physical barrier, protecting the frame of the bed body 1 from damage by splashing molten slag. Specifically, each funnel mechanism 3 includes several longitudinal guide plates 31 arranged inclined along the longitudinal direction (i.e., the length direction) of the bed, and several transverse guide plates 34 arranged inclined along the transverse direction (i.e., the width direction) of the bed. Multiple funnel mechanisms 3 are arranged side-by-side, separated from each other by longitudinal partitions 32 and transverse partitions 33. This partition design helps to create relatively independent negative pressure zones below the cutting area, thereby achieving more effective zoned dust collection.

[0021] The uppermost protective component 4 is fixedly installed on the funnel mechanism 3 and is the core component for resisting direct irradiation by high-energy lasers. Each protective component 4 covers one funnel mechanism 3 and the waste trolley 2 below it. It mainly consists of multiple L-shaped protective steel plates 43, two end plates (first end plate 41 and second end plate 42), and multiple support beams 44. The two end plates 41 and 42 are arranged opposite each other along the transverse side of the bed and are fixedly connected to the longitudinal partition 32 and transverse partition 33 of the funnel mechanism 3, respectively. The multiple support beams 44 are fixed at both ends between the two end plates 41 and 42. The multiple L-shaped protective steel plates 43 are made of heat-resistant metals such as stainless steel, extending longitudinally with their openings facing downwards, and their ends are directly supported on the support beams 44. These L-shaped protective steel plates 43 are arranged transversely along the bed and are divided into upper and lower layers arranged alternately. Specifically, the upper steel plate and the lower steel plate are offset in horizontal projection, and the lower steel plate is located directly below the gap between two adjacent upper steel plates. Viewed from directly above, this double-layered, staggered layout completely shields the scrap trolley 2 below, ensuring that laser beams from any angle cannot directly hit the trolley body. Simultaneously, the waste generated during cutting (such as small molten slag particles) can fall through the gaps between the upper steel plates, then be guided by the lower steel plate or pass directly through its side gaps, ultimately passing through the funnel mechanism 3 into the scrap trolley 2, ensuring an unobstructed descent path.

[0022] In practical applications, operators can periodically pull the fully loaded waste trolley 2 out along the guide rail, dump the waste, and then push it back to its original position; this can be operated by a single person. If the protective steel plate 43 is damaged due to long-term use, it can also be easily disassembled and replaced individually, resulting in low maintenance costs.

[0023] This utility model, through a triple structural design of a hollow bed, a guide funnel, and double-layered staggered L-shaped protective steel plates, not only ensures the rigidity of the equipment and achieves efficient dust removal and waste collection, but also completely solves the problem of high-power laser protection and greatly improves the convenience and economy of operation.

[0024] It should be noted that the above description is only a preferred embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any equivalent changes or modifications made by those skilled in the art to the structure, dimensions, connection methods, etc., within the scope of the claims, should be covered within the scope of protection of this utility model.
