Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1:

[0017] This utility model provides a protective device for preventing scrap splashing from a metal processing lathe, including a guide rail 1. Protective doors 2 are symmetrically installed on the guide rail 1. Each protective door 2 includes multiple first protective plates 3 and multiple second protective plates 4, arranged in an overlapping manner. A slide rail 5 is fixedly installed on each of the first protective plates 3, with limit plates 6 fixedly installed at both ends of the slide rail 5. A slider 7 is fixedly installed on each of the second protective plates 4, and the slider 7 is movably engaged with the slide rail 5. Baffles 9 are fixedly installed on both sides of the second protective plates 4 via pressure plates 8. The protective door 2 has an assembly opening 10, on which tempered glass 11 is fixedly installed. A pull handle 12 is also fixedly installed on the protective door 2. The baffles 9 are made of silicone rubber. An adsorption plate 13 is fixedly installed on the side of the protective door 2. A reinforcing bracket 14, made of stainless steel, is fixedly installed on each of the first protective plates 3.

[0018] Through the above technical solution, the guide rail 1 of this utility model is symmetrically equipped with protective doors 2. The protective doors 2 include multiple first protective plates 3 and multiple second protective plates 4. The first protective plates 3 and the second protective plates 4 are arranged in an overlapping manner. The first protective plates 3 are fixedly installed with slide rails 5. The second protective plates 4 are movably engaged with the slide rails 5 through sliders 7, so that the first protective plates 3 and the second protective plates 4 can move relative to each other, thereby realizing the opening and closing of the protective doors 2. The tempered glass 11 serves as an observation window, which makes it convenient for workers to observe the status of the lathe. The protective doors 2 prevent waste from splashing during the processing and protect the safety of the operator.

[0019] Example 2:

[0020] This embodiment mainly consists of a guide rail 1 and protective doors 2 symmetrically mounted on the guide rail 1. The protective doors 2 adopt a multi-layer structure design, including multiple first protective plates 3 and multiple second protective plates 4, which are arranged in an alternating pattern to form a complete protective barrier. The first protective plates 3 serve as fixed base components, and slide rails 5 are fixedly mounted on their surfaces. Limiting plates 6 are provided at both ends of the slide rails 5 to control the movement range of the protective doors 2. The second protective plates 4 serve as movable components, and a movable locking structure is formed between the second protective plates 4 and the slide rails 5 of the first protective plates 3 through a slider 7 fixed at their bottom, allowing the second protective plates 4 to slide smoothly along the slide rails 5.

[0021] The opening and closing mechanism of the protective door 2 adopts a sliding rail 5 and a slider 7. When the operator pulls the handle 12, the second protective plate 4 moves on the sliding rail 5 via the slider 7, thereby opening or closing the protective door 2. Pressure plates 8 are provided on both sides of the second protective plate 4. The pressure plates 8 firmly fix the baffles 9 to the second protective plate 4. These baffles 9 can effectively block the gap between the first protective plate 3 and the second protective plate 4, preventing small waste materials generated during processing from splashing out of the gap.

[0022] The protective door 2 has an assembly opening 10 in the middle, and a tempered glass observation window 11 is fixedly installed inside the assembly opening 10. The tempered glass 11 has high strength and impact resistance, which can not only ensure the safety of the operator, but also allow the operator to clearly observe the internal machining of the lathe. A handle 12 is fixedly installed on the outside of the protective door 2, which makes it easy for the operator to manually open or close the protective door 2.

[0023] The working principle of this protective device is as follows: When the lathe is machining metal parts, the protective door 2 is in the closed state, and the multi-layered, staggered protective plates form a complete protective barrier. When waste materials generated during machining splash, they are blocked by the protective door 2, and the baffle 9 prevents waste materials from flying out from the gaps between the protective plates. The operator can monitor the machining process in real time through the tempered glass observation window 11. When it is necessary to load or unload workpieces, the operator pulls the handle 12, and the second protective plate 4 moves on the slide rail 5 via the slider 7, so that the protective door 2 opens smoothly. When closing, the limit plate 6 ensures that the protective door 2 accurately resets and restores the protective state.

[0024] This protective device, through a combination of multi-layer protective plates, baffles 9, and tempered glass 11, effectively solves the safety hazard of scrap splashing during hardware processing. The slide rail 5 and slider 7 mechanism ensure the smooth opening and closing of the protective door 2, while the limit plate 6 ensures the accurate positioning of the protective door 2. The entire device has a simple and reliable structure, is easy to operate, and can effectively protect the safety of operators.

[0025] Example 3:

[0026] In this embodiment, the baffle 9 is made of silicone rubber and is fixedly installed on both sides of the second guard plate 4 by the pressure plate 8. The silicone rubber baffle 9 has good elasticity and flexibility, and can fit tightly into the movable gap between the first guard plate 3 and the second guard plate 4. When the protective door 2 is opened and closed, the silicone rubber baffle 9 will elastically deform as the second guard plate 4 moves, always maintaining the sealing effect on the gap.

[0027] During lathe machining, the silicone rubber baffle 9 effectively blocks flying metal scrap. Due to the high tear strength and abrasion resistance of silicone rubber, it will not easily break even when impacted by high-speed flying metal fragments. At the same time, silicone rubber has excellent high-temperature resistance, capable of withstanding the high-temperature metal fragments generated during lathe machining without deforming or failing due to high temperatures.

[0028] The silicone rubber baffle 9 is installed using a pressure plate 8 for fixation. This fixing method ensures the stability of the baffle 9 and facilitates future maintenance and replacement. When the baffle 9 wears out due to long-term use, a new baffle 9 can be quickly replaced simply by loosening the pressure plate 8, without disassembling the entire protective door 2 structure. The edges of the silicone rubber baffle 9 are designed with a rounded transition to avoid sharp corners, further improving safety performance.

[0029] In practical applications, the silicone rubber baffle 9 is used in conjunction with the tempered glass observation window 11 to ensure the airtightness of the protective door 2 without affecting the operator's observation of the processing. When the protective door 2 is closed, the silicone rubber baffle 9 will form a tight contact with the adjacent first protective plate 3, completely sealing any possible gaps. This design is particularly suitable for lathes used to process small metal parts, effectively preventing the splashing of tiny metal chips.

[0030] The thickness of the silicone rubber baffle 9 is optimized to ensure sufficient protective strength without affecting the smooth opening and closing of the protective door 2. Its surface is specially treated, giving it a certain degree of self-cleaning ability, which can reduce the adhesion of metal debris. When the protective door 2 is not used for a long time, the silicone rubber baffle 9 will naturally return to its original shape without permanent deformation.

[0031] The silicone rubber baffle 9 solution in this embodiment effectively protects against machining waste splashes from lathes through a perfect combination of material properties and structural design. Compared to traditional metal baffles 9, silicone rubber is lighter, more durable, and eliminates the risk of secondary collisions with metal debris. This protective device is particularly suitable for high-precision metalworking environments, ensuring safety without affecting the normal operation of the lathe.

[0032] Example 4:

[0033] In this embodiment, an adsorption plate 13 is fixedly installed on the side of the protective door 2, which can achieve a stable adsorption and fixation effect when the protective door 2 is closed. In this embodiment, the adsorption plate 13 adopts the principle of electromagnetic adsorption. When the protective door 2 is moved to the closed position, the adsorption plate 13 is tightly attached to the metal contact surface on the lathe frame. At this time, the adsorption plate 13 is energized by the control circuit to generate a strong electromagnetic field, so that a strong magnetic attraction is formed between the adsorption plate 13 and the metal contact surface, ensuring that the protective door 2 remains tightly closed during the processing.

[0034] The protective door 2 is composed of multiple alternating first protective plates 3 and second protective plates 4. This structural design allows the protective door 2 to form a continuous protective barrier when closed. The slide rails 5 installed on the first protective plates 3 cooperate with the sliders 7 on the second protective plates 4 to achieve smooth sliding of the protective door 2. When the protective door 2 is fully closed, the suction cup 13 automatically activates, generating sufficient suction force to fix the protective door 2 in the predetermined position, effectively preventing the protective door 2 from loosening or shifting due to vibration during processing.

[0035] The working state of the adsorption plate 13 is linked to the machining state of the lathe. When the lathe starts the machining program, the control system automatically activates the adsorption function of the adsorption plate 13; when machining is completed and the protective door 2 needs to be opened, the control system first cuts off the power to the adsorption plate 13 to eliminate the magnetic attraction before allowing the protective door 2 to move. This linkage control mechanism ensures both safety during machining and ease of operation.

[0036] The tempered glass observation window 11 on the protective door 2 is located at the assembly port 10, providing operators with a clear view of the processing area. The installation position of the suction cup 13 is carefully designed so as not to affect the field of view of the observation window while providing sufficient suction force. The suction cup 13 has a flat design and is flush with the side of the protective door 2 to avoid interference during the movement of the protective door 2.

[0037] When the protective door 2 is closed, multiple first protective plates 3 and second protective plates 4 are precisely aligned via the slide rail 5 and slider 7 system, ensuring the entire protective surface remains flat. At this time, the adsorption plate 13 is in complete contact with the lathe frame, ensuring a uniform distribution of adsorption force. The baffle 9 structure effectively fills the gaps between the protective plates and works in conjunction with the adsorption fixing device to form an all-round protective barrier, completely blocking the splashing of processing waste.

[0038] The adsorption plate 13 in this embodiment adopts a modular design for easy maintenance and replacement. An overload protection circuit is installed inside the adsorption plate 13, which automatically cuts off the power supply when the current is abnormal to prevent equipment damage. The adsorption force can be adjusted according to actual needs to accommodate protective doors 2 of different sizes and weights. The handle 12 of the protective door 2 is designed with ergonomic principles in mind, allowing for easy pulling of the protective door 2 after the adsorption plate 13 is released.

[0039] When the protective door 2 is closed, the suction force generated by the adsorption plate 13 is sufficient to resist the vibration and impact generated during processing. This fixing method is more reliable than traditional mechanical locking devices and will not wear or loosen due to long-term use. At the same time, the electromagnetic adsorption fixing method avoids the noise problems that may be caused by mechanical locking, thus improving the working environment.

[0040] This embodiment achieves reliable fixation of the protective door 2 in the closed state through the innovative application of the adsorption plate 13, effectively solving the problem of easy loosening of traditional protective devices. Combined with the staggered protective plate structure and the tempered glass 11 observation window, it ensures both protective effect and does not affect the observation and monitoring of processing operations, significantly improving the safety and convenience of the hardware processing process.

[0041] Example 5:

[0042] In this embodiment, a stainless steel reinforcing bracket 14 is fixedly installed on the first protective plate 3. The reinforcing bracket 14 extends along the length of the first protective plate 3, forming a stable frame structure with it. The reinforcing bracket 14 is fixedly connected to the first protective plate 3 by welding, using a continuous weld process to ensure the strength and sealing of the connection. The reinforcing bracket 14 has an L-shaped cross-section, with its vertical side fitting snugly against the first protective plate 3 and its horizontal side extending outwards to form a support surface. This structural design effectively increases the bending stiffness of the first protective plate 3.

[0043] The reinforcing bracket 14 is installed on the inner surface of the first guard plate 3, that is, on the side facing the lathe machining area. This arrangement allows the reinforcing bracket 14 to not only enhance rigidity but also serve as an auxiliary protective layer for the first guard plate 3, preventing splashed metal scrap from directly impacting the main body of the first guard plate 3. The length of the reinforcing bracket 14 matches the length of the first guard plate 3, extending from the top to the bottom of the first guard plate 3 to form a complete longitudinal support. Multiple triangular reinforcing ribs are also provided at the connection between the reinforcing bracket 14 and the first guard plate 3. These ribs are evenly distributed along the length of the bracket, further improving the stability of the connection.

[0044] When scrap material splashes during lathe machining, the first guard plate 3 absorbs the impact force from the machining area. Due to the presence of the reinforcing bracket 14, the overall rigidity of the first guard plate 3 is significantly improved, effectively resisting deformation caused by scrap impact. The L-shaped cross-section design of the reinforcing bracket 14 disperses the impact force over a larger area, reducing the risk of localized stress concentration. Simultaneously, the choice of stainless steel gives the reinforcing bracket 14 excellent corrosion resistance and wear resistance, enabling it to maintain structural integrity over a long period and adapt to the harsh environment of metal processing workshops.

[0045] During the opening and closing of the protective door 2, the first guard plate 3, as a fixed component, bears the force from the movement of the second guard plate 4. The reinforcing bracket 14 enhances the stability of the first guard plate 3 under dynamic loads, preventing deformation or loosening due to long-term use. The installation positions of the reinforcing bracket 14 and the slide rail 5 are coordinated to ensure that the slide rail 5 always remains straight, providing reliable support for the smooth sliding of the second guard plate 4. When the protective door 2 is fully closed, the reinforcing bracket 14 also plays an auxiliary sealing role, further reducing the gaps in the protective door 2 and improving the splash prevention effect in conjunction with the baffle 9.

[0046] This embodiment significantly improves the structural strength and stability of key components of the protective door 2 by incorporating a stainless steel reinforcing bracket 14 on the first guard plate 3. The special structural design of the reinforcing bracket 14 not only enhances the rigidity of the first guard plate 3 but also optimizes the force transmission path, enabling the protective device to more effectively resist the impact of scrap generated during processing, providing more reliable safety for operators. Simultaneously, this design maintains the lightweight and operational flexibility of the protective door 2, without affecting the normal use and maintenance of the lathe.
