[0002] In modern industrial manufacturing, laser cutting technology is widely used in numerous industries due to its advantages such as high precision and high efficiency. Among them, the chuck-type laser tube cutting machine is an advanced piece of equipment developed for specific processing needs, playing an important role in cutting long strip materials or complex-shaped workpieces.

[0003] Laser pipe cutting machines use high-intensity laser beams to cut pipes with high precision. The laser beams generated have extremely high energy density in the cutting area, and direct exposure can cause serious injury to operators. Traditional protective measures often focus on protecting the main laser source, such as the laser generator, while neglecting to design specific and comprehensive protection for the cutting area, which is the direct source of laser exposure risk. When operators are near the equipment performing routine tasks such as operation, debugging, loading, or unloading, they are easily exposed to laser light scattered or reflected from the cutting area, which can cause irreversible damage to their eyes and skin.

[0004] It is evident that existing technologies still need improvement and enhancement. Utility Model Content

Detailed Implementation

[0024] This utility model provides an outer enclosure structure for laser cutting. To make the purpose, technical solution, and effects of this utility model clearer and more explicit, the following describes this utility model in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit the scope of protection of this utility model.

[0025] Please see Figures 1-3 This utility model provides an outer enclosure structure for laser cutting, including a protective box 1 for enclosing a gantry and laser cutting components inside it; a feeding area 111 for feeding pipes is provided at the front of the protective box 1, and clearance areas 112 for a chuck to pass through are provided on the left and right sides of the protective box 1; a front protective curtain 31 is provided at the front of the protective box 1 to cover the feeding area 111; and side protective curtains 32 are provided on the left and right sides of the protective box 1 to cover the clearance areas 112.

[0026] The gantry spans the front and rear sides of the side-mounted bed 10. The chuck can reciprocate along the Y-axis / length / left-right direction of the side-mounted bed 10. Therefore, clearance areas 112 are provided on the left and right sides of the protective housing 1 to avoid the chuck. Cut pipes or short / tailed materials can be unloaded from the unloading area 111, which can hold a unloading box for receiving materials. This unloading area 111 also facilitates operator access to the interior of the protective housing 1 during non-operating hours of the laser pipe cutting machine.

[0027] Specifically, the front protective curtain 31 and the side protective curtain 32 are preferably black fireproof curtains. Black has a strong ability to block the light generated by lasers, and the fireproof curtains are made of fireproof materials, which can prevent the fireproof curtains from melting due to heat, thereby extending the service life of the fireproof curtains.

[0028] The protective enclosure 1 encloses the gantry and laser cutting components. When the operator is outside the enclosure, it effectively blocks laser scattering and reflection during the cutting process, preventing laser leakage and potential injury. Furthermore, the protective enclosure 1, in conjunction with the front protective curtain 31 and side protective curtains 32, provides comprehensive laser protection. Moreover, the protective enclosure 1 is constructed of sheet metal, allowing for the centralized installation of gas source treatment and other related components for easy adjustment.

[0029] Please see Figure 1 , Figure 2 and Figure 4 In some embodiments, the lower surface of the protective housing 1 is provided with a first clamping piece 2 and a second clamping piece 3. The upper part of the front protective curtain 31 and the upper part of the side protective curtain 32 are clamped between the first clamping piece 2 and the second clamping piece 3 by fasteners. In practical applications, the first clamping piece 2, the second clamping piece 3, and the front protective curtain 31 or the side protective curtain 32 are modularly designed. During assembly, the modular whole is installed to the corresponding position on the protective housing 1. When it is necessary to replace the front protective curtain 31 and the side protective curtain 32, the corresponding locking parts are removed and new front protective curtain 31 and the side protective curtain 32 are replaced. Disassembly and assembly are convenient. In addition, the first clamping piece 2 and the second clamping piece 3, together with the fasteners, clamp and fix the upper part of the front protective curtain 31 and the side protective curtain 32. This connection method can ensure that the front protective curtain 31 and the side protective curtain 32 are stably attached to the protective housing 1 during use.

[0030] Please see Figure 4 In some embodiments, the fasteners are screws / bolts / screws and nuts (not shown in the figure). The first clamping plate 2 and the second clamping plate 3 have multiple through holes 21 extending along their length, and the fasteners are located in the corresponding through holes 21. Both the front protective curtain 31 and the side protective curtain 32 are made of soft material, so the screws / bolts / screws can be passed through the corresponding through holes 21 and through both sides of the front protective curtain 31 and the side protective curtain 32. Finally, the fasteners are clamped in the gap between the first clamping plate 2 and the second clamping plate 3 by the nuts to complete the assembly. Then, the modular integrated structure is installed in the corresponding position on the protective housing 1.

[0031] Please see Figure 1 and Figure 2In some embodiments, a viewing window 113 is provided at the front of the protective housing 1, and a transparent window 114 is provided within the viewing window 113. During the laser cutting operation, the operator needs to observe the situation in the cutting area in real time to understand the cutting progress, the pipe cutting status, and whether there are any abnormalities. The transparent window 114 allows the operator to clearly see the working status of the laser cutting components inside the protective housing 1 through the viewing window 113, ensuring the smooth progress of the cutting work while avoiding the risk of injury from direct exposure to laser radiation. Specifically, the transparent window 114 is preferably radiation-proof glass.

[0032] In some embodiments, the protective housing 1 includes a lower housing 11 and an upper housing 12 communicating with the lower housing 11. The length of the upper housing 12 along the Y-axis is less than the length of the lower housing 11 along the Y-axis. The upper housing 12 is used to accommodate the laser cutting component drive mechanism. Since the cutting area covers a wide range, the lower housing 11 needs to be designed to be relatively large. However, the moving area of ​​the laser cutting component and the Z-axis cable chain mounted on the gantry is relatively small, so the upper housing 12 needs to be designed to be smaller. This arrangement avoids wasting space and makes the spatial layout and volume of the protective housing 1 more reasonable.

[0033] In some embodiments, a support base 20 and a baffle 4 are also provided between the side-mounted bed 10 and the gantry frame. The baffle 4 is located within the avoidance area 112, and the support base 20 is located below the baffle 4. The front side wall of the baffle 4 is fixed to the gantry frame, and the rear side wall of the baffle 4 is fixed to the side-mounted bed 10. In practical applications, the lower surface of the front part of the gantry frame is fixed to the support base 20, and the lower surface of the rear part is fixed to the side-mounted bed 10. Since there is a certain distance between the support base 20 and the laser cutting assembly, the baffle 4 is provided. The baffle 4 cooperates with the protective housing 1 to further reduce the escape of laser light from the cutting area. To further improve the laser shielding effect of the baffle 4, an arc-shaped groove adapted to the lower curvature of the chuck is also provided on the upper part of the baffle 4.

[0034] In some embodiments, the support base 20 is a hollow structure, and an exhaust pipe 5 is provided between the support base 20 and the side-mounted bed 10. The exhaust pipe 5 passes through the left and right sides of the support base 20 and the front and rear sides of the side-mounted bed 10. The exhaust pipe 5 is connected to an exhaust device. This arrangement can quickly remove dust generated in the cutting area, protecting the working environment. Moreover, the exhaust pipe 5 is relatively short, making full use of the positions of the side-mounted bed 10 and the support base 20, resulting in a more rational design.

[0035] In some embodiments, a baffle 6 is provided on the side wall of the support base 20 facing the cutting area; the baffle 6 is used to cover the air inlet of the exhaust pipe 5 inside it; the baffle 6 is also provided with an exhaust hole 61. The baffle 6 covers the air inlet of the exhaust pipe 5, which can effectively guide the smoke and exhaust gas generated during laser cutting to flow to the exhaust hole 61. In addition, the cutting area also involves the unloading area 111, so the baffle 6 can also prevent the short pipe / tail material from falling and directly contacting the exhaust pipe 5 and damaging it.

[0036] In some embodiments, the sidewall of the baffle 6 is configured as an inclined surface; the inclined surface faces upward, and the exhaust hole 61 is disposed on the inclined surface. The inclined surface can guide the tail material falling onto the baffle 6, so as to prevent the tail material from blocking the exhaust hole 61 on the baffle 6 after falling onto the baffle 6, thereby affecting the exhaust effect.

[0037] In some embodiments, an electrical control cabinet 7 is provided at the rear of the protective enclosure 1. The electrical control cabinet 7 allows all electrical components within the equipment to be integrated into the cabinet, facilitating maintenance and management, and making the electrical components readily visible.

[0038] In summary, this utility model encloses the gantry and laser cutting components within a protective enclosure 1. When the operator is outside the protective enclosure 1, it effectively blocks laser scattering and reflection during the cutting process, preventing laser leakage and potential injury. Furthermore, the protective enclosure 1, in conjunction with the front protective curtain 31 and the side protective curtains 32, provides comprehensive laser protection.
