Description

Technical Field

[0001] The utility model relates to the technical field of cutting, in particular to a cutting machine used for preparing porous heat-insulating materials. Background Art

[0002] A cutting machine is a machine specially used to separate metal structures to be cut. It relies on mechanical drive to achieve the cutting function. During the cutting process, the cutting tool is usually a high-speed rotating disc. When the cutting tool first contacts the part to be cut, the impact force generated by the high-speed operation is large. Therefore, the cutting speed of the tool needs to be reduced in the early stage of cutting to protect the tool from damage.

[0003] However, when the part to be cut is a porous insulation material, the situation becomes complicated. This material has many holes inside, which brings challenges to the cutting process. Conventional cutting machines maintain a constant speed during cutting, but when the cutting tool encounters a hole inside the porous insulation material, it will generate a large impact force. Especially when a certain point on the cutting tool contacts the edge of the hole, the impact force will be particularly obvious, combined with Figure 1 , point a on the cutting knife contacts point b on the hole. However, the cutting machine cannot automatically identify the location of the hole during operation, so it cannot automatically reduce the cutting speed when encountering a hole, which increases the risk of tool damage.

[0004] In order to solve the above problems, the utility model proposes a cutting machine specially used for preparing porous thermal insulation materials. Utility Model Content

[0005] In view of the above-mentioned technical deficiencies, the purpose of the utility model is to provide a cutting machine specially used for the preparation of porous thermal insulation materials, which can reduce the impact force of the holes on the cutting tool.

[0006] In order to solve the above technical problems, the utility model adopts the following technical solutions: The utility model provides a cutting machine for preparing porous thermal insulation materials, comprising a housing, which is mounted on a driving component for driving the cutting machine to move;

[0007] An inner shell is installed inside the outer shell, and the inner shell is used to install a cutting tool;

[0008] A cylinder is fixed on the inner shell, a circular groove matching with the cylinder is provided on the outer shell, the cylinder is inserted into the circular groove, an annular gap is left between the circular groove and the cylinder, and a first buffer part is provided inside the annular gap.

[0009] Preferably, the first buffer portion comprises:

[0010] A first ring body, on which a curved surface 1 is provided, the curved surface 1 is annular, and the concave surface of the curved surface 1 is provided on the outer ring surface of the first ring body;

[0011] A second ring body is provided with a second curved surface, the second curved surface is annular, and the concave surface of the second curved surface is arranged on the inner ring surface of the second ring body;

[0012] The first ring body and the second ring body are sleeved with each other, and an annular buffer chamber can be formed between the first curved surface and the second curved surface.

[0013] Preferably, two side edges of the second ring body are pressed against the first curved surface.

[0014] Preferably, one side edge of the first ring body abuts against the side wall of the circular groove, and the other side edge abuts against the inner shell.

[0015] Preferably, the first ring body and the second ring body can form a buffer group, and the number of the buffer groups is multiple, and the diameters of the multiple buffer groups are different and they are mutually sleeved.

[0016] Preferably, a gap is left between the outer shell and the inner shell, and a second buffer portion is provided in the gap.

[0017] Preferably, the second buffer portion includes a plurality of elastic bodies and fixing members for fixing the elastic bodies, and two ends of the elastic bodies are respectively connected to the outer shell and the inner shell.

[0018] Preferably, the plurality of elastic bodies are arranged in the gap on a side away from the moving direction of the cutting machine.

[0019] The beneficial effects of the utility model are as follows: firstly, by arranging a cylinder and a circular groove between the outer shell and the inner shell, and leaving an annular gap therebetween, the first buffer portion arranged inside the annular gap can quickly play a buffering role when the cutting tool encounters the hole inside the component, thereby reducing the impact force of the hole edge on the cutting tool, thereby protecting the cutting tool.

[0020] Secondly, the setting of the second buffer further enhances the performance of the cutting machine. It not only provides support for the inner shell, ensuring that the cutting tool can quickly return to its original position after being displaced by impact and resume cutting, but also reduces vibration and noise to a certain extent, improving the quality and efficiency of cutting operations.

[0033] The present invention is described below with specific embodiments, but is not intended to be a limitation of the present invention.

[0034] Embodiment 1

[0035] like Figure 1-Figure 5 As shown, in this embodiment, a cutting machine for preparing porous thermal insulation materials is provided, including an outer shell 1 and an inner shell. The outer shell 1 is installed on a driving component for driving the cutting machine to move, and the outer shell 1 can transport linear motion along the cutting direction on the driving component; the inner shell 2 is installed inside the outer shell 1, and the inner shell 2 is used to install a cutting tool. The cutting device is usually equipped with a disc-shaped cutting tool. A motor for driving the cutting tool is installed in the inner shell. In this embodiment, the motor can drive the cutting tool to rotate through a bevel gear. When the cutting machine is running, the cutting tool will rotate at a high speed inside the machine. During the rotation, the cutting tool will contact the part to be processed and perform precise cutting operations on it.

[0036] A cylinder 3 is fixed on the inner shell 2, and a circular groove 4 matching with the cylinder 3 is provided on the outer shell 1. The cylinder 3 is inserted into the circular groove 4, and an annular gap is left between the circular groove 4 and the cylinder 3. A first buffer portion 5 is provided inside the annular gap. The first buffer portion 5 is installed in the annular gap and can buffer the inner shell 2, and the inner shell 2 can buffer in all directions.

[0037] Embodiment 2

[0038] On the basis of the first embodiment, this embodiment provides a form of the first buffer portion 5, which is as follows:

[0039] The first buffer part 5 includes a first ring body 51 and a second ring body 52. ​​The first ring body 51 is provided with a curved surface 1, which is annular, and the concave surface of the curved surface 1 is arranged on the outer ring surface of the first ring body 51. One side of the first ring body 51 abuts against the side wall of the circular groove 4, and the other side abuts against the inner shell 2 to reduce the shaking of the first ring body 51. The second ring body 52 is provided with a curved surface 2, which is annular, and the concave surface of the curved surface 2 is arranged on the inner ring surface of the second ring body 52. ​​The two sides of the second ring body 52 abut against the curved surface 1, and both the first ring body 51 and the second ring body 52 can be deformed.

[0040] The first ring body 51 and the second ring body 52 are connected to each other, and an annular buffer chamber can be formed between the curved surface 1 and the curved surface 2. The mutual connection of the curved surface 1 and the curved surface 2 can form a plurality of clearance spaces between the first buffer body and the second buffer body, and the inner and outer annular surfaces of the first buffer portion 5 can respectively abut against the two annular surfaces of the annular gap, thereby having a buffering effect on the inner shell 2, and then having a buffering effect on the cutting knife. The first ring body 51 and the second ring body 52 can form a buffer group, and the number of the buffer groups is multiple groups, and the diameters of the multiple buffer groups are different and are connected to each other, combined with Figure 1 The buffer group includes a first ring body 51 and a second ring body 52. ​​This embodiment provides two buffer groups.

[0041] Embodiment 3

[0042] On the basis of the first and second embodiments, this embodiment provides a second buffer structure, which is as follows:

[0043] There is a gap between the outer shell 1 and the inner shell 2, and a second buffer part 6 is provided in the gap. The first buffer part 5 and the second buffer part 6 have a buffering effect on the inner shell 2 at the same time. The second buffer part 6 includes a plurality of elastic bodies 61 and a fixing member 62 for fixing the elastic body 61. The two ends of the elastic body 61 are respectively connected to the outer shell 1 and the inner shell 2. The second elastic body 61 points to the axis of the cylinder 3, and provides secondary buffering for the inner shell 2. The plurality of elastic bodies 61 are arranged in the gap on the side away from the moving direction of the cutting machine to overcome the movement of the inner shell 2, so that the inner shell 2 can quickly return to its position after moving.

[0044] Working principle: A circular cutting tool is installed on the cutting device, which is installed on the inner shell 2. When the cutting operation is performed, the outer shell 1, the inner shell 2 and the cutting device are pushed to move as a whole, so that the cutting tool can accurately cut the part to be processed. When the cutting tool encounters a hole inside the part during the cutting process, the first buffer 5 and the second buffer 6 will quickly play a role, effectively buffering the impact force generated by the edge of the hole on the cutting tool. At the same time, the second buffer 6 can also provide support for the inner shell 2 and the cutting device, ensuring that after the cutting tool is displaced by the impact, it can quickly return to its position and continue cutting. This design can protect the cutting tool.
