Description
Technical Field
The invention relates to a heat energy deburring device, in particular to a device which is applied to removing burrs of a workpiece by utilizing gas explosion combustion.
Background
Burrs or flanging are generated on occasions such as machining, die casting and the like in the manufacturing process of parts. Although the burrs are small, the burrs are harmful, so that the burrs affect the processing of the subsequent process, and the burrs block the pore passages and scratch parts. Particularly, in the occasions where fluid passes through such as pneumatics, hydraulics, automobiles, aerospace and the like, the burrs block the pore channels and block the valve core, so that very serious quality accidents are caused. Deburring of parts is an extremely important production process, and some big burrs and turn-ups can be got rid of through the manual work at present, but the cost of labor is high, still can produce secondary burr. For small burrs, especially those which cannot be seen by naked eyes, or those in complicated channels, the burrs cannot be removed at all by manual means.
The basic principle of the heat energy deburring process is that a workpiece needing deburring is placed on a base of a combustion chamber (a basket and a clamp are selected), the base of the combustion chamber rises to be attached to the combustion chamber and clamped to form a closed combustion chamber space, then fuel gas with certain pressure and oxygen are introduced to form a combustible gas mixture (the inflation pressure is generally 0.3-2 MP), the combustible gas mixture is ignited and exploded by a spark plug to generate instant high temperature and high pressure (the average pressure is 20 times of the inflation pressure, and the impact pressure is 20-100 times), and burrs of the machined workpiece are removed. Because the combustion and explosion time of the mixed gas is extremely short (2-3 us) and the temperature is extremely high (2500-3000 ℃), burrs and fins of parts can be rapidly combusted into ash-shaped oxides. And after the combustion is finished, exhausting the waste gas out of the combustion chamber, opening the combustion chamber, and manually taking out the workpiece.
According to the principle of thermal deburring, the equipment at least needs a main body frame, a combustion chamber system for combustion and explosion of fuel gas, a device capable of clamping the combustion chamber system, and an inflation and exhaust system for charging the combustion chamber with fuel gas and oxygen and simultaneously discharging combusted or non-combusted gas. A set of control systems is used for controlling the logical actions of the elements and realizing the monitoring of the state of the equipment.
Since the explosion pressure and explosion temperature of the equipment are very high, the high temperature and high pressure of these explosions are confined in a combustion chamber system. Firstly, the combustion chamber system needs to bear huge impact force (20-100 times of impact pressure) and extremely high temperature (3500 ℃), and needs to have enough strength rigidity, high temperature resistance and heat dissipation capacity; secondly, in the process of deburring by heat energy, a large amount of oxidized powder is generated, and the cavity is extremely easy to corrode under the conditions of surplus oxygen, moisture and high temperature, so that the combustion cavity is required to have enough corrosion resistance; and thirdly: the combustion chamber cover plate convenient for putting in the workpiece is the weakest part of the combustion chamber, and has good sealing performance, especially has reliable sealing performance in the explosion process, so that the explosion gas can be leaked outwards when the combustion chamber cover plate is not closed, equipment is damaged when the combustion chamber cover plate is not closed, and major safety accidents are caused when the combustion chamber cover plate is closed. Fourthly, when the combusted gas is discharged to the outside through the channel, a large amount of oxides or combusted particles can be generated when the workpiece is combusted, the oxides or the particles can pollute the sealing surface of the sealing element when being discharged through the system, the sealing element can not be completely attached together, the sealing fails, and the combusted gas can leak to ablate the sealing surface after the sealing fails, so that the sealing element is damaged. This forms the vicious circle. This requires that the sealing surface have a certain dirt resistance and self-cleaning ability; fifthly, in order to achieve reliable sealing, strong pressing force is required, and a bracket system with enough strength is required to resist the impact force of deformation; and the sixth step: since this process is a special process and has very high safety requirements, it is necessary to ensure the reliability of the equipment, in particular of some consumables, such as seals. The state of the main components can be detected in real time through a control software system, and detailed recording and early warning are required; seventhly, due to the specialty of the equipment, the requirement on equipment maintenance engineers is very high, and the original plant engineers are often needed to perform maintenance guidance and fault diagnosis on the equipment.
