Embodiment 1

[0028] Such as figure 1 .

[0029] A method for removing burrs from slender blind holes based on the tip effect induced sulfide reaction, which includes the following steps:

[0030] The first step is to pour sulfur powder into the bottom of the slender blind hole. The amount of sulfur powder should cover the burr area; the purity of the sulfur powder used is preferably above 99.99%; the slender hole that needs to be cleaned should be vertical Location, the same below;

[0031] The second step is to install the exhaust gas collection device in the slender orifice; the exhaust gas collection device can be an inverted cone glass cover, the glass cover is connected with a balloon or air bag with a built-in 10% sodium hydroxide absorption solution to collect the generated during the reaction Exhaust and purify;

[0032] In the third step, the parts are energized as a whole, and the energizing voltage is DC 24-48V. The burr temperature is increased by using the characteristics of small bu...

Embodiment 2

[0035] Such as figure 2 Shown.

[0036] A method for removing burrs from slender and vertical through holes based on the tip effect inducing a sulfide reaction, which includes the following steps:

[0037] In the first step, first use a plug (such as a rubber stopper or other non-chemically reactive soft plug) to block the horizontal hole to prevent sulfur powder from running out of the horizontal hole during the reaction, and then pour the sulfur powder into the elongated horizontal hole In the vertical holes, the amount of addition is appropriate to cover the burr area; the purity of the sulfur powder used is preferably above 99.99%

[0038] The second step is to install the exhaust gas collection device in the slender orifice; the exhaust gas collection device can be an inverted cone glass cover, the glass cover is connected with a balloon or air bag with a built-in 10% sodium hydroxide absorption solution to collect the generated during the reaction Exhaust and purify;

Embodiment 3

[0042] Such as image 3 .

[0043] A method for removing burrs from two or more slender blind holes based on the tip effect induced sulfide reaction, which includes the following steps:

[0044] The first step is to pour sulfur powder into the bottom of two or more slender blind holes. The amount of sulfur powder should cover the burr area; the purity of the sulfur powder used is preferably above 99.99%; the burr needs to be cleaned in specific cases. The slender holes should be in a vertical position, or partly vertical and partly inclined; the slender blind holes in the horizontal state should be divided into sections. After the vertical blind holes are cleaned, they should be turned 90 degrees to make them vertical, and then repeat steps one to four;

[0045] The second step is to install an exhaust gas collection device at the slender orifice; the exhaust gas collection device can be an inverted cone glass cover, and then use a balloon or air bag with a 10% concentration of sodi...

Abstract

Provided is a slender hole deburring method based on tip-effect-induced pyrite reaction. The slender hole deburring method includes the steps that elemental sulfur is firstly poured into the bottom ofa slender hole, then an exhaust gas collecting device is installed on the slender hole, then a whole part is energized, and the characteristics of minimum sectional area of burrs and maximum value ofresistance are used for increasing the temperature of the burrs and inducing the pyrite reaction, so that the burr in the slender hole can be removed. According to the slender hole deburring method,burrs of complex structural parts such as a complex cavity, a penetrating and crossing hole system, a deep hole, and a blind hole has high adaptivity, and the burrs of different positions of parts canbe removed at the same time, not only the burrs are removed completely but also the efficiency is high.

Description

Technical field [0001] The invention belongs to the technical field of mechanical processing, and relates to a method for deburring slender pores, in particular to a method for deburring slender pores based on a sharp point effect inducing a sulfide reaction. Background technique [0002] In the metal cutting process, various processing methods will produce burrs to varying degrees, which often appear at the junction or edge of the two surfaces, generally appearing as tiny sharp protrusions. The existence of burrs seriously affects the quality and accuracy of parts or products. Taking the elongated hole as an example, it is mostly used as a working medium flow channel in hydraulic or pneumatic components. After the burr falls off during use, once it enters the circuit of the hydraulic or pneumatic system, it will not only cause the moving parts to jam, the circuit or the filter screen, etc., causing accidents, but also cause fluid turbulence or non-laminar flow, reducing the hyd...
