Abstract
The utility model discloses a sealing device for laser cutting head, which comprises a main part of laser head and a focusing component. Between the related main part of laser head and the focusing component is provided with a sealing device. The utility model has a good elastic deformation capacity. The center provides a flexible support to enhance the flexibility and when gets high pressure, sealing on both sides adhere to both sides of the movement and the more pressure the stronger conglutination is so can maintain efficient airproof in the movement.
Description
[technical field]
The utility model relates to a kind of cutting head of laser cutting machine, more specifically, relates to the sealing device of laser cutting head.
[technical background]
Laser cutting machine is widely used in industrial every field, require cutting head to bear higher pressure (25MPa) at cutting technique, and can keep high efficiency at the volley, and in the prior art, the main part and the focusing component of cutting head do not have hermetically-sealed construction, cause leaking gas in the cutting process, do not reach job requirement.
[summary of the invention]
For addressing the above problem, the utility model provides a kind of elevated pressures of bearing, the laser cutting head sealing device of cloth gas leakage.
The utility model adopts following technical scheme: a kind of laser cutting head sealing device, comprise laser head main part and the focusing component that is attached thereto, and establish a sealing device between described laser head main part and the focusing component.
Further improvement of the utility model is that the described sealing device that connects is the sealing ring of center with the U-shaped cross section of elastomer support.
The beneficial effect that the utility model can reach is, between the cutting head main part of laser cutting head and focusing component, establish a sealing device, can organize cutting desired gas cloth to drain to the outside from the inside effectively, thereby guarantee the desired high pressure of cutting head technology, and, this part has the better elastic deformability, its center is supported to strengthen elasticity with elastomer, and when being subjected to high pressure, both sides sealing spare is close to the motion both sides, pressure is higher, and subsides power is stronger.
[description of drawings]
The invention will be further described in conjunction with the embodiments with reference to the accompanying drawings.
Fig. 1 is the front view of the utility model laser cutting head sealing device.
Fig. 2 is the zoomed-in view of sealing device part of the present utility model.
[specific embodiment]
See also Fig. 1, laser cutting head sealing device of the present utility model, comprise laser cutting head main part 1, with the focusing component 2 that is attached thereto, one sealing device 3 is set between main part and focusing component, sealing device is to prevent any seal of leaking gas, and what the utility model adopted is the sealing ring with U type cross section of nylon material injection mo(u)lding, has good elastic deformability.See also Fig. 2, the enlarged drawing of sealing device, wherein, the centre of seal 3 sees that by elasticity 5 support, seal 3 is close to the movement parts both sides.In the course of work, movement parts 4 is done radial motion along direction 7, it is motionless that fixture 6 keeps, and gases at high pressure enter cutting head from 8, because the influence that is subjected to entering gas pressure, elastic component has the lateral expansion of direction 9, along with entering increasing of gas, pressure also increases gradually, and seal 3 both sides also can be pasted tightly more with the motion both sides, can in motion process, prevent the gas leak phenomenon of cutting head effectively, keep efficient sealed.
Claims (2)
1. a laser cutting head sealing device comprises laser head main part and the focusing component that is attached thereto; It is characterized in that: establish a sealing device between described laser head main part and the focusing component.
2. laser cutting head sealing device according to claim 1 is characterized in that: the described sealing device that connects is the sealing ring of center with the U-shaped cross section of elastomer support.
