Description

Technical Field

[0001] The present invention relates to the technical field of cutting and punching, and in particular to a laser heating cutting and punching machine and a laser heating cutting and punching method. Background Art

[0002] In modern manufacturing, the demand for precise cutting and punching of materials is increasing day by day. Especially when dealing with special materials such as prepreg (PP), traditional machining methods often fail to meet the requirements for precision, efficiency, and material properties. For example, Patent CN202210639256.1 proposes a laser heating cutting machine and its cutting method, which uses a laser emitter and a cutter to perform preheating and final cutting operations respectively, thus effectively achieving longitudinal and transverse cutting of prepreg materials. By this method, not only the cutting accuracy is improved, but also the thermally damaged area is reduced, ensuring the quality of the material.

[0003] However, with the diversification of the processing requirements for PP materials in industrial production, the deficiencies in the existing technical solutions have gradually emerged. Specifically, the technical solution of CN202210639256.1 mainly focuses on the cutting function and does not involve drilling treatment for PP materials. This results in the need to use additional special equipment or manual tools for secondary processing when it is necessary to complete cutting and drilling operations on the same device in practical applications, greatly reducing production efficiency, increasing costs, and possibly decreasing processing accuracy due to multiple clamping.

[0035] As Figures 1 - 5 shown, an embodiment of the first aspect of the present invention provides a laser heating cutting and punching machine.

[0036] A laser heating cutting and punching machine, comprising a machine table 1, a longitudinal cutting mechanism 2, a punching mechanism 3 and a transverse cutting mechanism 4. A roller transmission mechanism 5 is arranged on the machine table 1. The longitudinal cutting mechanism 2, the punching mechanism 3 and the transverse cutting mechanism 4 are sequentially arranged on the outer periphery of the roller transmission mechanism 5 from front to back. The longitudinal cutting mechanism 2 includes a first cross bar 6, a first laser heating device 7 and a first cutting tool 8. Both ends of the first cross bar 6 are connected to the machine table 1. The first laser heating device 7 and the first cutting tool 8 are arranged on the first cross bar 6. The punching mechanism 3 includes a second cross bar 9 and a plurality of punching devices 10. Both ends of the second cross bar 9 are connected to the machine table 1. The punching devices 10 are arranged on the second cross bar 9. The transverse cutting mechanism 4 includes a third cross bar 11, a second laser heating device 12 and a second cutting tool 13. Both ends of the third cross bar 11 are connected to the machine table 1. The second laser heating device 12 and the second cutting tool 13 are arranged on the third cross bar 11.

[0037] In the present invention, by integrating the cutting and punching functions on one device, the problems of multiple clamping and the use of multiple devices in the traditional process are avoided, greatly improving the production efficiency and reducing the operation time and cost. By using the first laser heating device 7 and the second laser heating device 12 to preheat the material respectively, the stability and consistency of the material during the cutting process are ensured, effectively preventing quality problems caused by local overheating or uneven cooling. This device is not only applicable to semi-cured sheet materials, but also can process various other types of materials, having strong adaptability and flexibility.

[0038] It can be understood that the first laser heating device 7 is located at the front end of the first cutting tool 8.

[0039] A laser heating cutting and punching machine according to this embodiment, a buffer mechanism 14 is arranged between the longitudinal cutting mechanism 2 and the punching mechanism 3. The buffer mechanism 14 includes two first lifting driving cylinders 15, a transition plate 16 and floating rollers 17.

Two ends of the floating roller 17 are respectively rotatably connected to the brackets 18. It can be understood that when the roller transmission mechanism 5 works continuously, the longitudinal cutting mechanism 2 can cut along with the movement of the PP material. However, when the punching mechanism 3 and the transverse cutting mechanism 4 work, the PP material needs to remain relatively stationary. In this embodiment, by arranging the buffer mechanism 14, when the punching mechanism 3 and the transverse cutting mechanism 4 work, the roller transmission mechanism 5 does not need to stop working. The PP material cut by the front longitudinal cutting mechanism 2 can be carried on the bottom of the floating roller 17 and moved by the first lifting driving cylinder 15, so that the PP material located at the punching mechanism 3 and the transverse cutting mechanism 4 is relatively stationary, which is convenient for punching and transverse cutting the PP material. The above setting enables the roller transmission mechanism 5 to work continuously without stopping during punching and transverse cutting, greatly improving the work efficiency.

[0040] It can be understood that the buffer mechanism 14 includes a transition plate 16. Two ends of the transition plate 16 are respectively connected to the tops of the two first lifting driving cylinders 15.

[0042] It can be understood that the first fixing frame 19, the second fixing frame 20 and the punching device 10 can be assembled according to the actual needs of the product, and the positions of the first fixing frame 19 and the second fixing frame 20 and the number of the punching devices 10 can be adjusted.
