Description

Technical Field

[0001] The utility model belongs to the technical field of laser cutting machines, and in particular relates to a novel nozzle cooling device. Background Art

[0002] As a high-precision machine tool, flat laser cutting machines have been gradually widely used in various industries. With the continuous increase in demand, the power is gradually moving towards the level of 10,000 watts or even 100,000 watts. The existing cutting heads are facing huge challenges in dealing with such high-power processing environments, and the cooling effect of the cutting heads and cutting head nozzles is facing huge challenges. At present, most machine tools use relatively large laser power when processing thick plates. At the same time, long-term cutting will cause the cutting nozzle temperature to be too high or even burnt. In this processing environment, it is difficult to ensure long-term, high-stability cutting. Utility Model Content

[0003] The utility model aims to provide a novel nozzle cooling device to solve the problems existing in the background technology.

[0004] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a new nozzle cooling device, comprising an anti-collision connector, a cooling nozzle body, a cooling nozzle and a sealing ring, the cooling nozzle having a cutting head in the middle, threads being arranged at both ends of the anti-collision connector, the upper end being connected to the bottom of the cutting head, and the lower end being connected to the cooling nozzle, the cooling nozzle body and the sealing ring being directly sleeved on the anti-collision connector, and being tightened and fixed by the cooling nozzle and the anti-collision connector, the cooling nozzle and the cooling nozzle body having concentric air holes, which are evenly arranged in a circular array.

[0005] Preferably, the anti-collision connector automatically disconnects when a collision or lateral force occurs during the cutting process.

[0006] Preferably, high-pressure cooling gas is ejected from the concentric air holes.

[0007] Preferably, the cutting head and the cooling nozzle are an integrated structure, and concentric air holes are distributed around the cutting head.

[0008] The beneficial effects of the utility model are as follows: the device and its simple structure realize the function of cooling the nozzle without adding other auxiliary components, greatly expanding the processing capacity of machine tool cutting, solving the common problems in the industry that the nozzle is seriously heated during the thick plate cutting process and the capacitor temperature drift leads to unstable cutting quality. At the same time, the anti-collision connector is used to connect the nozzle body and the cutting head, which greatly reduces the customer's loss when a collision occurs. Therefore, it can quickly respond to new demands in the market, maintain customer satisfaction, and play a positive role in improving the company's overall image. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The specific implementation of the utility model is described in detail below with reference to the accompanying drawings and preferred embodiments.

[0014] like Figure 1-4 As shown, a novel nozzle cooling device comprises: an anti-collision connector 1, a cooling nozzle body 2, a sealing ring 3 and a cooling nozzle 4. The cooling nozzle and the cooling nozzle body have concentric air holes, which are evenly arranged in a circular array. The anti-collision connector is provided with threads at both ends, the upper end is connected to the bottom of the cutting head, and the lower end is connected to the cooling nozzle. The cooling nozzle body and the sealing ring are directly sleeved on the anti-collision connector, and are tightened and fixed by the cooling nozzle and the anti-collision connector. In the actual cutting process, high-pressure cooling gas is blown out from the air holes at the bottom of the cutting head, first collected in the cooling nozzle body, and then sprayed into the outer ring of the copper cooling nozzle through the circular hole at the lower end, and flows out through the air holes of the outer ring of the cooling nozzle. The accumulated heat on the copper nozzle due to high-power cutting can be quickly taken away through the gas flow, thereby achieving a fast and stable cooling effect. The connection between the nozzle and the nozzle body is sealed with a high-heat-resistant sealing ring, which plays a gas sealing effect.

[0015] In addition, during the processing, relatively weak parts will be reserved on the anti-collision connector, which will be disconnected when a collision occurs. At the same time, the cooling nozzle will fall off along with the cooling nozzle body. The cutting head will send a stop command due to abnormal capacitance, and the cutting action will stop immediately, thereby preventing further losses caused by a collision.

[0016] Each component is equipped with threads that can cooperate with each other, and is fixed by thread locking. The anti-collision connector at the top connects the cooling solution as a whole to the cutting head. At the same time, when a collision occurs during the cutting process and a lateral force occurs, it will disconnect automatically. At the same time, the capacitor will feedback a break signal to the system and shut down in time to play a role in collision protection. This device and its simple structure realize the function of nozzle cooling without adding other auxiliary components, greatly expanding the processing capacity of machine tool cutting, and solving the common problems in the industry that the nozzle heats up severely during the thick plate cutting process and the capacitor temperature drift leads to unstable cutting quality.

[0017] This device solves some working conditions that require high quality during high-power cutting of flat surfaces with a simple structure. At the same time, it can be quickly disassembled and replaced to meet the diversity of customer needs during actual processing, save manpower and material resources for customers, and improve production stability.

[0018] It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be regarded as the protection scope of the utility model.
