Description
The utility model relates to a kind of cutting torch of NC flame cutting machine.It is characterized in that: it can make cutting torch do unlimited revolution.
Look into newly by retrieval, domestic have only limited-rotary (0-360) cutting torch, and application number is that 94205984 Chinese utility application has been announced a kind of burning torch rifle mouth whirligig, is exactly wherein a kind of.The cutting torch of limited-rotary, cutting steel plate X, V, Y, K type groove can not once-formings, need cutting repeatedly, and steel plate is yielding, also wastes energy.
The purpose of this utility model is the weak point that remedies the limited-rotary cutting torch, makes cutting torch can do unlimited revolution, is 5-150mm when being cut steel plate thickness, and cutting X, V, Y, K type groove time processing are shaped, and bevel angle is adjustable in the 5-45 scope.
The purpose of this utility model is to realize like this, the core of the unlimited revolution of flame three cutting torch devices is gas rotary sealing bodies, require sealing property to be perfectly safe reliably, avoid blast, require cutting oxygen, preheat oxygen, combustion gas by the rotary sealing body time, must not ventilate mutually and seepage, realize limit revolution, limit cutting.When cutting, requirement can be adjusted the cutting torch angle at any time according to the variation of bevel angle in addition.
The utility model is made of the unlimited rotating part of cutting torch, cutting torch angle adjustment part, cutting torch position adjusting section.Unlimited rotating part (as shown in Figure 1) comprises servomotor (1), reductor (2), shaft coupling (3), seal case (4), stuffing box (5), sealing ring (6), axle (7), adjusts bolt (8), bearing (9), silencer (10) etc.Stuffing box (5), silencer (10) and compressed air joint are fixed on the seal case (4), axle (7) has logical respectively cutting oxygen from top to bottom, preheat oxygen, three cannelures of joints such as combustion gas, seal ring set that quantity do not wait is arranged between each cannelure on axle (7), and the elasticity between sealing ring (6) and the axle (7) can be adjusted by adjusting bolt (8), assurance axle (7) rotates freely and is air tight, sealing ring is made with soft graphite or magnetic fluid, it is between stuffing box (5) and axle (7), each inlet suction port one end is fixed on the seal case (4), and the other end is fixed on the stuffing box (5).
Cutting torch angle adjustment part (as Fig. 2, shown in Figure 3) is by servomotor (1), reductor (2), shaft coupling (3), screw (4), leading screw (5), ball bearing (6), tooth bar (7), gear (8), bearing (9), Connection Block (10), holddown groove formations such as (11).Servomotor (1) is connected with reductor (2), and gear (8) is fixed on the reductor (2), gear (8) and tooth bar (7) engaged transmission, and tooth bar (7) is made sliding motion in holddown groove (11), realize the cutting torch angle adjustment.The cutting torch position adjusting section is connected with screw (4) by Connection Block (10), screw (4) is supported by two bearings (9), transmission by servomotor (1), reductor (2), shaft coupling (3), leading screw (5), screw (4) drives the cutting torch translation and finishes the adjustment of cutting torch position, and wherein leading screw (5) two ends are supported by ball bearing (6).
When the unlimited rotating part of cutting torch is worked (as shown in Figure 1), to adjust cutting oxygen, preheat oxygen, three kinds of gas pressures of combustion gas in advance according to steel plate thickness, each road gas enters each cannelure of rotary sealing body from entering the mouth separately respectively, enter corresponding each hole in the output shaft again, be transported to three cutting torches through joint and pipeline then.Drag output shaft (7) when infinitely turning round when servomotor (1) like this, each road gas air admission hole is communicated with corresponding cannelure all the time, and the burning torch air feed is continuous all the time with regard to having realized cutting torch to do unlimited revolution like this.On the other hand, owing to realize that by soft graphite or magnetic fluid seal ring each road gas seals each other between each cannelure, and a small amount of seepage gas can be blown down away by silencer (10) by compressed air, and this has just guaranteed that this device can work safely and reliably, can not blast.
The adjustment of bevel angle realizes (as shown in Figure 3) by changing the cutting torch angle, the control signal that servomotor (1) receiving computer sends, drag harmonic wave speed reducing machine (2) driven gear (8) tooth bar (7) is rotated, drive the cutting torch rotation and realize that bevel angle is adjustable in the 0-45 scope.When adjusting another cutting torch angle, 3. realize by driving servomotor.
Cutting torch position adjusting section (as shown in Figure 2), servomotor (1) are accepted computer control signal and are dragged harmonic wave speed reducing machine (2) drive leading screw (5) rotation, make screw (4) moving linearly, drive the cutting torch straight line and move.When adjusting another cutting torch position, 2. realize by driving servomotor.The utility model compared with prior art has following advantage:
1. owing to adopt unlimited revolution three cutting torches to replace the limited-rotary cutting torch, thus be 5-150mm when being cut steel plate thickness, but cutting X, V, Y, K shape groove once-forming, and bevel angle is adjustable in the 5-45 scope.
2. owing to sealing ring in the gas rotary sealing body is made with soft graphite or magnetic fluid, be connected with mobile compressed air between seal case (4) and the stuffing box (5), sealing ring between each cannelure is according to the difference of all gases pressure and do not wait, so its sealing property is safe and reliable, can realize limit revolution, limit cutting.
3. because whole cutting process is controlled automatically by computer programming,, do not need manual intervention so be cut the part shape and bevel angle can be adjusted automatically in cutting process.
