Embodiment 1

[0021] A drilling process for fastening bolts, comprising the following specific steps:

[0022] S1. Clean the surface of the bolt with a steel wire, then wash it with clean water, dry it and set it aside. The temperature of the clean water is 55°C, the number of cleanings is 1 time, the drying temperature is 70°C, and the drying time is 1h;

[0023] S2. After taking out the bolt, evenly coat a layer of solvent on the surface of the bolt to be drilled. The solvent includes the following components in parts by weight: 35 parts of alcohol ether phosphate, 31 parts of polyvinyl alcohol, sodium alkylbenzene sulfonate 22 parts, 15 parts of naphthenic oil, 18 parts of alkylphenol polyoxyethylene ether, 5 parts of antioxidant and 11 parts of aminotriacetic acid;

[0024] S3. First, use a thin drill bit smaller than the set hole diameter to drill the center hole, and then use a thick drill bit with the same size as the set hole diameter to start drilling from the center hole, and spra...

Embodiment 2

[0028] A drilling process for fastening bolts, comprising the following specific steps:

[0029] S1. Clean the surface of the bolt with a steel wire, then wash it with clean water, dry it and reserve it for later use. The temperature of the clean water is 60°C, the number of cleanings is 3 times, the drying temperature is 85°C, and the drying time is 1.5h;

[0030] S2. After taking out the bolt, evenly coat a layer of solvent on the surface of the bolt to be drilled. The solvent includes the following components in parts by weight: 46 parts of alcohol ether phosphate, 37 parts of polyvinyl alcohol, sodium alkylbenzene sulfonate 30 parts, 18 parts of naphthenic oil, 23 parts of alkylphenol polyoxyethylene ether, 9 parts of antioxidant and 13 parts of aminotriacetic acid;

[0031] S3. First, use a thin drill bit smaller than the set hole diameter to drill the center hole, and then use a thick drill bit with the same size as the set hole diameter to start drilling from the center...

[0035] A drilling process for fastening bolts, comprising the following specific steps:

[0036] S1. Clean the surface of the bolt with a steel wire, then wash it with clean water, and dry it for later use. The temperature of the clean water is 58°C, the number of cleanings is 2 times, the drying temperature is 75°C, and the drying time is 1.2h;

[0037] S2. After taking out the bolt, evenly coat a layer of solvent on the surface of the bolt to be drilled. The solvent includes the following components in parts by weight: 40 parts of alcohol ether phosphate ester, 35 parts of polyvinyl alcohol, sodium alkylbenzene sulfonate 26 parts, 17 parts of naphthenic oil, 20 parts of alkylphenol polyoxyethylene ether, 7 parts of antioxidant and 12 parts of aminotriacetic acid;

[0038] S3. First, use a thin drill bit smaller than the set hole diameter to drill the center hole, and then use a thick drill bit with the same size as the set hole diameter to start drilling from the center hole...

Abstract

The invention discloses a punching process of a fastening bolt. The punching process includes the following specific steps that the surface of the bolt is completely washed with a steel wire, and thesurface is completely washed with clean water and dried for use; after the bolt is taken out, the to-be-punched surface of the bolt is evenly coated with a layer of solvent; a cooling agent is evenlysprayed to the punched position in the punching process; the hole surface of the punched bolt is finely machined, the hole surface is completely washed with clean water after being purged, and the bolt is fed into an oven to be dried; and the dried bolt surface and the dried hole surface are coated with anti-corrosion paint, and the finished bolt is obtained. The working efficiency is high, the punching accuracy is improved, and abrasion of a drill bit is reduced.

Description

technical field [0001] The invention belongs to the technical field of bolt processing, and in particular relates to a drilling process for fastening bolts. Background technique [0002] Bolt is widely used in the middle of commercial production manufacture at daily life, can be used in electronic product, engineering goods, power equipment, water conservancy engineering, even also useful bolt is in the chemical experiment. Most of the traditional drilling process uses drill bits with the same diameter to directly drill holes, which causes great wear and tear on the drill bit, and the drilling accuracy is not high. In view of this, it is necessary to improve the traditional drilling process for fastening bolts. Contents of the invention [0003] In order to solve the deficiencies of the prior art, the object of the present invention is to provide a drilling process for fastening bolts with high working efficiency, improved drilling accuracy, and reduced drill bit wear. ...
