Embodiment 1

[0022] The invention provides a method for thermal energy deburring, the steps of which are:

[0023] Step 1, place the part 7 to be processed on the fixture, wherein, such as figure 1 and figure 2 As shown, the fixture includes a base plate 1, and the parts to be processed 7 are placed on the base plate 1. The parts to be processed 7 are arranged around the central axis of the base plate 1, and a first screw 4 is respectively arranged on both sides of each part to be processed 7. A screw 4 limits the left and right of the part 7 to be processed. The first screw 4 is fixed on the base plate 1. The two ends of the part 7 to be processed are respectively pressed and fixed by the pressure ring 2 and the pressure plate 3. The bottom plates 1 are fixedly connected by the first screw rod 5 and the nut 6 .

[0024] The design and processing of the fixture are relatively simple. All the parts in the fixture are made of heat-resistant stainless steel. When designing, it is only nece...

Embodiment 2

[0030] The difference between this embodiment 1 and embodiment 2 is that in step 3, the mixed gas of methane and oxygen is passed into the airtight container, and the part 7 to be processed is made of QT500-7 material. Therefore, the feeding pressure of methane is 3bar, the inlet pressure of oxygen is 3bar. Other steps are identical with embodiment 1.

Abstract

The invention provides a deburring method based on heat energy, and the method is characterized by comprising the following steps of: placing a part to be processed on a fixture; then placing the fixture on which the part to be processed is well placed into a closed container; introducing the mixed gas of hydrogen and oxygen or the mixed gas of methane and oxygen into the closed container; igniting by use of an ignition device so as to quickly burn the mixed gas introduced into the closed container; and after the burning, taking out the fixture to finish the deburring. In the whole deburring process, as gas goes everywhere and has good accessibility, the method provided by the invention has a unique effect in removing burr or flash of the part. The method can be used for realizing the processing of multiple parts in a relatively short time due to the fixture and meeting the need for large-scale production, has a wide application range, and can be applied to the parts made from iron, cast iron, brass, aluminum, zinc, copper and the like. The method has the advantages of high efficiency, good deburring quality and the like, and is simple and convenient to operate.

Description

technical field [0001] The invention relates to a method for deburring the surface of a key part in a hydraulic element and its internal complex structure by using heat energy. Background technique [0002] The burrs on the parts are mainly produced during the processing. If the burrs are not cleaned, the parts are easy to form solid particles during use, which will affect the cleanliness of the hydraulic components. The cleanliness of hydraulic components is the key to the reliability of the hydraulic system and the service life of the components. If the cleanliness of the hydraulic components is not good, it will cause many hazards: first, it will cause the hydraulic components to be stuck and malfunction, such as the directional valve does not change direction, the flow valve flow adjustment fails, the servo valve is unstable, etc.; second, the pollutants enter The friction motion pair will aggravate the wear of hydraulic components, causing surface strain of key hydrau...
