TECHNICAL FIELD
[0001] The utility model relates to the field of metal sheet cutting device, concretely to a cutting device of stainless steel sheet. BACKGROUND
[0002] The stainless steel sheet is a kind of metal material with thin thickness, and its thickness is usually between 0.2 to 4 millimeters, but it can also be customized to be thinner or slightly thicker according to specific requirements. This material is mainly composed of chromium, nickel and a small amount of other alloy elements and iron, and has excellent corrosion resistance, high temperature resistance and good mechanical properties. The surface of the stainless steel sheet is smooth, easy to clean and maintain, and beautiful and elegant, so it is widely used in architectural decoration, kitchenware manufacturing, food processing, chemical equipment, medical devices, automobile parts and many other industrial and civilian fields. Before specific application, the stainless steel sheet often needs to be accurately cut using high-precision laser cutting equipment according to design drawings or actual requirements to ensure accurate size and smooth edge, meeting the requirements of subsequent processing or installation.
[0003] The thickness of the stainless steel sheet is different, and accurate control is needed when setting the laser cutting equipment. If it is not controlled, there will be a significant temperature difference between the cutting area and the surrounding area due to large temperature gradient, which not only causes uneven distribution of internal stress of the material, and further causes problems such as cutting edge quality decline, deformation warping, crack fracture, but also affects the stability and service life of the cutting equipment. At this time, a new type of cutting device for stainless steel sheet is needed, which can efficiently cut without the need for precise adjustment of the laser cutting equipment. SUMMARY
[0004] Therefore, the utility model aims at providing a cutting device for stainless steel sheet to solve the technical problems of cutting edge quality decline, deformation warping, crack fracture and impact on the stability and service life of the cutting equipment caused by large temperature gradient during laser cutting of stainless steel sheet with different thickness.

[0007] By adopting the above technical scheme, the laser cutting machine ensures the accuracy and efficiency of cutting by virtue of its high precision and rapid cutting capacity.
[0008] Further, one side of the heating guide wire is provided with a temperature sensor, and the temperature sensor is used for real-time monitoring of the preheating temperature.

[0012] Further, the plate slot is provided with a steel sheet.
[0013] By adopting the above technical scheme, the steel sheet is accurately clamped in the plate slot and placed below the heating guide wire, which ensures smooth preheating and cutting operation and helps to improve the precision of cutting, because the steel sheet will not move or shake during cutting.
[0014] Further, the top two sides of the plate slot are provided with two clamp seats, and the top of the clamp seat is provided with a bolt plate.
[0015] By adopting the above technical scheme, the combination of the clamp seat, the bolt plate and the clamping bolt provides a firm clamping force for the stainless steel sheet.
[0016] Further, bolt holes are formed in the two bolt plates, and clamping bolts are screwed in the bolt holes.
[0017] By adopting the above technical scheme, by tightening the clamping bolt, it can be ensured that the steel sheet will not move during cutting, thereby ensuring the accuracy and safety of cutting, and this setting also helps to protect the steel sheet from damage.
[0018] Furthermore, two clamp blocks are provided at the bottom of the clamping bolt, and the clamp blocks are used to clamp the steel sheet.
[0019] By adopting the above technical solution, the clamp block set at the bottom of the clamping bolt directly contacts the steel sheet, providing a more uniform and stable clamping force, which helps prevent the steel sheet from being deformed or damaged due to uneven clamping force during the cutting process.
[0020] Furthermore, a second mounting seat is provided at the top rear end of the base, a protective cover is installed on the top of the second mounting seat, a fourth linear motor is provided in the protective cover, and a laser cutting head is provided at the bottom movable end of the fourth linear motor.
[0021] By adopting the above technical solution, the second mounting seat and protective cover set at the rear end of the base provide stable support and protection for the laser cutting head. Driven by the fourth linear motor, the laser cutting head can perform cutting operations accurately. The design of the protective cover ensures safety during operation and prevents the laser beam from being directly exposed to the operating environment and causing harm to the operator.
[0022] In summary, the present invention has the following beneficial effects:
[0023] The utility model sets a preheating mechanism and accurately controls the third linear motor and the first mounting seat through an external control center, so that the preheating seat can move flexibly in the vertical direction and cooperate with the first linear motor to ensure that the preheating mechanism is accurately positioned on a two-dimensional plane, thereby ensuring the uniformity of the preheating effect. The heating guide wire equipped on the preheating seat effectively reduces the thermal stress during cutting by uniformly preheating the stainless steel sheet, and significantly improves the cutting quality. At the same time, the design of the heat dissipation hole cleverly solves the problem of heat accumulation generated during the preheating process, protecting the preheating mechanism and the steel sheet from overheating damage. The temperature sensor monitors the preheating temperature in real time to ensure that the preheating process is carried out within the optimal temperature range, which not only prevents the material from being damaged due to overheating, but also ensures the achievement of the preheating effect, further improving the stability of the cutting quality.
