Method for producing conductive screw

Abstract

The invention discloses a method for producing a conductive screw rod, and relates to the conductive screw rod with the purpose of solving the great hidden danger of cutter breakage during deep hole machining. According to the technical scheme, the method for producing the conductive screw rod is characterized by comprising the following specific steps of A, casting, B, rough machining, C, drilling and D, assembly, wherein in the step A, 1, raw materials, namely, molten metal and a graphite rod are provided, 2, equipment, namely a casting press and a mould are provided, and 3, a working flow is as follows: after the graphite rod is vertically fixed in the mould, molten metal is injected into the mould, and the mould is pressurized by the press, so that a blank is formed under pressure; and in the step C, 1, equipment, namely, a drilling machine is provided, and 2, a working flow is as follows: a drill bit of the drilling machine is aligned with the graphite rod, and the graphite rod is pulverized and drilled away from a roughing material so that the roughing material with a deep hole is formed. According to the method for producing the conductive screw, the deep hole is formed by drilling the graphite rod with the drilling machine, and since the hardness of the graphite rod is far lower than that of a casting piece, the problem of the cutter breakage is effectively prevented.

Description

technical field [0001] The present invention relates to electrically conductive screws, and more particularly, it relates to a method for producing electrically conductive screws. Background technique [0002] A cigarette lighter is a car device whose main function is to light a cigarette. When the cigarette lighter is pressed in, the heating part is embedded in the bimetal sheet of the cigarette lighter socket, and a loop is formed inside, the circuit is turned on, and the resistance wire will be heated to a temperature sufficient to make the cigarette burn (1050-1100°C). , the user can use to light a cigarette. [0003] The conductive screw is an important part of the cigarette lighter socket. On the same day, the applicant submitted an invention patent for a conductive screw used in a car cigarette lighter, such as Figure 7 As shown, the technical points are as follows: including a conductive post 1, the top of the conductive post 1 is provided with an external thread p...

Problems solved by technology

[0004] The above-mentioned conductive screw needs to be provided with a deep hole 6. In the prior art, the deep hole is generally processed by a drilling machine or a machining center. However, it is found in actual production that due to the small diameter and deep depth of the deep hole 6, Therefore, slender tools must be used for processing, resulting in a large hidden danger of tool breakage when processing deep holes 6; therefore, a new solution needs to be proposed to solve this problem
