Description
Technical Field
The utility model belongs to the technical field of plasma cutting equipment, concretely relates to plasma cutting nozzle.
Background
In plasma cutting, the nozzle is often the main consumable and plays a critical role, so it is very important to reduce the cost of the nozzle without affecting the quality. The plasma cutting nozzle of prior art formula structure as an organic whole usually, inconvenient change nozzle head, at the plasma cutting in-process, plasma arc acts on the work piece through the jet orifice of nozzle, and the jet orifice plays the effect of gathering the arc, because plasma arc periphery still has higher temperature, the high temperature resistant effect of current nozzle head is poor, consequently easily burns out at the anterior segment of nozzle and jet orifice, influences injection efficiency. In addition, the whole nozzle is generally replaced in the replacement process of the existing nozzle, which is not beneficial to reducing the production cost.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a plasma cutting nozzle to prior art not enough, concrete scheme is as follows:
a plasma cutting nozzle comprises a first mounting seat and a second mounting seat in threaded connection with the first mounting seat, wherein a nozzle head is arranged inside the first mounting seat, an arc gathering cavity, a channel and a conical opening are sequentially formed inside the nozzle head from back to front, and a ceramic coating is coated on the inner wall of the nozzle head; the bottom of first mount pad is equipped with first sealing washer, the tip of second mount pad be equipped with the first seal groove that first sealing washer corresponds, the bottom of nozzle head is equipped with the second seal groove, the tip of second mount pad be equipped with the second sealing washer that the second seal groove corresponds.
Based on the above, a first flange is arranged inside the first mounting seat, a second flange corresponding to the first flange is arranged on the periphery of the nozzle head, a plurality of positioning columns are uniformly distributed on the first flange along the circumferential direction, and a plurality of positioning holes corresponding to the positioning columns are arranged on the second flange.
The utility model discloses relative prior art has substantive characteristics and progress, specifically speaking, the utility model has the following advantages:
1. in the utility model, the nozzle head is arranged in the first mounting seat and is fixed by the second mounting seat which is screwed with the first mounting seat, and the structural design facilitates the disassembly and the assembly of the nozzle head; in addition, the ceramic coating is coated in the nozzle head, so that the service life of the nozzle head is greatly prolonged, and the practicability of the whole nozzle is improved.
2. The utility model discloses in, through the inside at first mount pad be equipped with first flange, be equipped with in the periphery of nozzle head with the second flange that first flange corresponds is equipped with a plurality of reference columns along the circumference equipartition on the first flange, be equipped with on the second flange a plurality of with the locating hole that the reference column corresponds, this structure can prevent that the nozzle from making the nozzle head take place to rotate because of the impact force of electric arc at the during operation to ensure whole nozzle mounting structure's stability.
Drawings
Fig. 1 is a schematic diagram of a structure in which the first mounting seat and the second mounting seat are separated from each other.
Fig. 2 is a schematic view of the overall structure of the present invention.
In the figure: 1. a first mounting seat; 2. a second mounting seat; 3. a nozzle head; 4. a ceramic coating; 5. a positioning column; 6. a first seal ring; 7. a first seal groove; 8. a second seal ring; 9. a second seal groove; 10. a arcing chamber; 11. a channel; 12. a conical mouth.
Detailed Description
The technical solution of the present invention will be described in further detail through the following embodiments.
Examples
As shown in fig. 1-2, the utility model provides a plasma cutting nozzle, including first mount pad 1 and with second mount pad 2 of first mount pad 1 spiro union, the inside of first mount pad 1 is equipped with nozzle head 3, the inside of nozzle head 3 is from backward to forward in proper order for converging arc chamber 10, passageway 11 and bell mouth 12, considers the influence of the high temperature electric arc of nozzle when using, has high temperature resistant ceramic coating 4 at the inner wall coating of nozzle head 3.
In order to facilitate the fixed installation of the nozzle head 3, a first sealing ring 6 is arranged at the bottom of the first installation seat 1, a first sealing groove 7 corresponding to the first sealing ring 6 is arranged at the end of the second installation seat 2, a second sealing groove 9 is arranged at the bottom of the nozzle head 3, and a second sealing ring 8 corresponding to the second sealing groove 9 is arranged at the end of the second installation seat 2.
In view of the fact that the nozzle head 3 may rotate due to the impact force of the arc when the nozzle works, and thus the stability of the whole nozzle mounting structure is affected, a first flange is arranged inside the first mounting seat 1, a second flange corresponding to the first flange is arranged on the periphery of the nozzle head 3, a plurality of positioning posts 5 are uniformly distributed on the second flange along the circumferential direction, and a plurality of positioning holes corresponding to the positioning posts 5 are arranged on the second flange.
The utility model discloses a structural design to nozzle head 3 itself reforms transform with and mounting structure, has promoted 3 life of nozzle head and installation effectiveness by a wide margin to the practicality of whole nozzle has been promoted.
Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
