Description

Technical Field

[0001] This utility model relates to the field of laser cutting processing technology, and more specifically, to a cutting device for flange processing. Background Technology

[0002] A flange, also called a flange plate or flange, is a part used to connect shafts to each other. It is used for connecting pipe ends, and also for connecting two pieces of equipment at the inlet and outlet.

[0003] Currently, steel plates need to be laser-cut to produce flanges. The specific process involves connecting a laser cutter to a five-axis device and pre-setting the cutting trajectory. Then, the outer circle contour of the flange is first cut on the steel plate. After the outer circle contour is cut, the bolt holes and center holes of the flange are cut in sequence. The existing steel plates lack limiting means during the cutting process, which makes it easy for the position to be offset, affecting the laser cutting effect. At the same time, after cutting, several flanges need to be manually collected into a fixed area in sequence, so the labor intensity needs to be reduced. Utility Model Content

[0004] The purpose of this invention is to solve the problems mentioned in the background art and to propose a cutting device for flange processing.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0006] A flange processing cutting device includes a five-axis device and a laser cutter connected to the five-axis device. It is characterized by further including a cutting table, a saw blade, an electromagnetic limiting assembly, a CCD camera, a placement slot, a collection box, a three-axis device, and an electromagnetic adsorption assembly.

[0007] Several serrated blades are fixed at equal intervals on the cutting table;

[0008] The electromagnetic limit component is fixed on the cutting table and is located on one side of several saw teeth.

[0009] A CCD camera is fixed on the cutting table to capture and identify the laser-cut area;

[0010] The placement slot is located on the cutting table, and a collection box is placed inside the placement slot;

[0011] The three-axis equipment is fixed on the cutting table and is connected to an electromagnetic adsorption component to automatically transfer and collect the flanges after laser cutting.

[0012] Furthermore, the electromagnetic limiting component includes a limiting plate and several electromagnetic plates. A limiting plate located on one side of several serrated bars is fixed on the cutting table, and several electromagnetic plates are equidistantly fixed on the limiting plate, which are distributed alternately with the serrated bars.

[0013] The above solution uses an electromagnetic limiting component to limit the horizontal position of the steel plate based on the serrated support. After the limit is set, the steel plate is firmly attracted by an electromagnetic plate to prevent positional displacement during subsequent laser cutting.

[0014] Furthermore, the electromagnetic adsorption assembly includes a mounting rod and an electromagnet. The three-axis device is connected to the mounting rod, and electromagnets that are symmetrically fixed on the mounting rod in contact with the bolt hole processing area of ​​the flange.

[0015] The above solution can lock the area of ​​a flange after laser cutting is completed using a CCD camera. When the laser cutter moves away from the flange, it will send a signal to the controller to control the electromagnetic adsorption component to move accurately to the area for automatic transfer and collection of the flange.

[0016] Furthermore, a suction pipe is fixed on one side of the laser cutter on the five-axis device. One end of the suction pipe is connected to a suction hood that is higher than the laser cutter and arranged at an angle. The other end of the suction pipe is connected to a negative pressure fan fixed on the five-axis device. The negative pressure fan is connected to a smoke purifier fixed on the five-axis device through a negative pressure air duct.

[0017] The above solution generates smoke and gas during laser cutting. Then, a negative pressure fan is activated, and the smoke and gas are then purified by a smoke purifier through a suction hood and suction pipe, thus avoiding the problem of smoke filling the environment around the cutting table.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] Compared to existing technologies, this device can process flanges using laser cutting, and its position can be effectively limited during the flange cutting process to avoid deviation that could affect the cutting effect. After a flange is cut, its position can be automatically identified, and then the electromagnetic adsorption component can automatically transfer and collect it into a collection box for storage, thereby greatly reducing the labor intensity of manual picking and making the laser cutting process of flanges more effective.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model. The present utility model will be further described with reference to the accompanying drawings and embodiments:

[0026] like Figure 1 and Figure 2 As shown, a flange processing cutting device includes a five-axis device (not fully shown in the figure, belonging to the prior art, and its working principle is not described) and a laser cutter connected to the five-axis device. It also includes a cutting table 1, a saw blade 2, an electromagnetic limit assembly, a CCD camera 5, a placement slot 6, a collection box 7, a three-axis device 8, and an electromagnetic adsorption assembly.

[0027] Several toothed blades 2 are fixed at equal intervals on the cutting table 1;

[0028] The electromagnetic limiting component is fixed on the cutting table 1, and the electromagnetic limiting component is located on one side of several saw teeth 2.

[0029] CCD camera 5 is fixed on cutting table 1 to capture and identify the laser cutting area;

[0030] The placement slot 6 is located on the cutting table 1, and a collection box 7 is placed inside the placement slot 6;

[0031] The three-axis device 8 is fixed on the cutting table 1, and the three-axis device 8 is connected to an electromagnetic adsorption component to automatically transfer and collect the flange after laser cutting.

[0032] Further refinements of the embodiments of this utility model, such as... Figure 1 As shown, the electromagnetic limiting assembly includes a limiting plate 3 and several electromagnetic plates 4. The limiting plate 3 is fixed on one side of several serrated bars 2 on the cutting table 1, and several electromagnetic plates 4 are fixed on the limiting plate 3 at equal intervals and distributed alternately with the serrated bars 2.

[0033] Further refinements of the embodiments of this utility model, such as... Figure 1As shown, the electromagnetic adsorption assembly includes a mounting rod 9 and an electromagnet 10. The triaxial device 8 is connected to the mounting rod 9, and electromagnets 10 are symmetrically fixed on the mounting rod 9 to contact the bolt hole processing area of ​​the flange.

[0034] It should be noted that the five-axis device, laser cutter, electromagnetic sheet 4, CCD camera 5, and electromagnet 10 are all electrically connected to the controller, which is shown in the figure without a label.

[0035] The working process of this utility model is as follows:

[0036] First, the steel plate is placed on several toothed strips 2. The toothed strips 2 can effectively disperse the stress and heat generated during laser cutting, thereby reducing the risk of damage to the cutting table 1. At the same time, the toothed strips 2 can also stably support the steel plate to improve the accuracy of subsequent laser cutting. It should be noted that the thickness of the steel plate to be cut is 10-15MM. During the placement process, the long side of the steel plate is made to fit with the limiting plate 3 to horizontally limit the position of the steel plate. Then, the controller controls several electromagnetic plates 4 to be energized synchronously to achieve multi-point position limitation of the steel plate.

[0037] Once the steel plate is stably positioned, the five-axis equipment drives the laser cutter to perform the laser cutting process on the flange according to a pre-set program (specifically including cutting the outer contour of the flange, the center hole, and several bolt holes; the cutting process is existing technology and will not be improved). During the laser cutting process, the CCD camera 5 can capture and identify the current area in real time. After the flange cutting in the current area is completed, the CCD camera 5 locks onto the flange area. Then, the five-axis equipment first drives the laser cutter away from the top of the flange, and then the controller controls the three-axis equipment 8 to operate, thereby causing the electromagnet 10 to move to directly above the flange. When magnet 10 descends, it comes into contact with the bolt hole processing area of ​​the flange. After adsorption, the electromagnetic adsorption component moves up to achieve automatic adsorption and transfer of the flange. It should be noted that the cutting parameters and the type of auxiliary gas are pre-adjusted so that the flange and steel plate will not stick after cutting. Then, the flange can be transferred to the collection box 7 for storage by the electromagnetic adsorption component. After the automatic transfer and collection of one flange is completed, the laser cutting process of the next flange can begin. Then, the CCD camera 5 can re-capture and identify the next laser cutting area and automatically complete the electromagnetic adsorption transfer after the laser cutting of the next flange is completed.

[0038] Compared to existing technologies, this device can process flanges using laser cutting, and its position can be effectively limited during the flange cutting process to avoid deviation that could affect the cutting effect. After a flange is cut, its position can be automatically identified, and the electromagnetic adsorption component will automatically transfer and collect it into the collection box 7 for storage, thereby greatly reducing the labor intensity of manual picking and making the laser cutting process of flanges more effective.

[0039] In some embodiments, such as Figure 3 As shown, a suction pipe 11 is fixed on one side of the laser cutter on the five-axis device. One end of the suction pipe 11 is connected to a suction hood 12 that is higher than the laser cutter and arranged at an angle. The other end of the suction pipe 11 is connected to a negative pressure fan 13 fixed on the five-axis device. The negative pressure fan 13 is connected to a smoke purifier 14 fixed on the five-axis device through a negative pressure duct. In this embodiment, smoke and gas are generated during the laser cutting process. Then, the negative pressure fan 13 works and the smoke and gas can be introduced into the smoke purifier 14 through the suction hood 12 and the suction pipe 11 for purification, thereby avoiding the problem of smoke filling the environment around the cutting table 1.
