Embodiment 1

[0027] Such as figure 2 As shown, the preparation method of the composite signal plate is as follows:

[0028] Step 1: Prepare the signal plate body 1 made of Q235 material, with a relative permeability of 3500 (the permeability of air is 1).

[0029] Step 2: Remove the oil on the signal plate body 1.

[0030] Step 3: heating the signal plate body 1 to 850-870° C., cooling in oil, heating to 550-570° C., tempering for 100 minutes, and cooling to obtain the quenched and tempered signal plate body 1 .

[0031] Step 4: Put the quenched and tempered signal panel body 1 into the bluing treatment solution, and keep it warm at 135-145°C for 50 minutes to obtain the signal panel body 1 that has undergone quenching and tempering and bluing treatment; the bluing treatment solution contains An aqueous solution of sodium hydroxide, sodium nitrite, and sodium nitrate, wherein the concentration of sodium hydroxide is 15mol / L, the concentration of sodium nitrite is 3mol / L, and the concent...

Embodiment 2

[0036] Step 1: Prepare the signal plate body of 1215 free-cutting steel, with a relative permeability of 800-1000 (assuming that the permeability of air is 1).

[0037] Step 2: Remove the oil on the signal plate body.

[0038] Step 3: Heat the signal plate body to 850-870° C., cool in oil, heat to 550-570° C., temper for 180 minutes, and cool to obtain the quenched and tempered signal plate body.

[0039] Step 4: Put the quenched and tempered signal plate body into the bluing treatment solution, and keep it warm for 40 minutes at 135-145°C to obtain the signal plate body that has undergone quenching and tempering and bluing treatment; the bluing treatment solution contains hydrogen oxidation An aqueous solution of sodium, sodium nitrite, and sodium nitrate, wherein the concentration of sodium hydroxide is 13mol / L, the concentration of sodium nitrite is 4mol / L, and the concentration of sodium nitrate is 0.7mol / L.

[0040] Step 5: Laser quench the edge of the signal plate body ...

Embodiment 3

[0044] Step 1: Prepare the signal plate body made of cast iron, with a relative permeability of 500 (the permeability of air is 1).

[0045] Step 2: Remove the oil on the signal plate body.

[0046] Step 3: Heat the signal plate body to 850-870°C, cool in oil, then heat to 550-570°C, temper for 180 minutes, and cool to obtain the quenched and tempered signal plate body.

[0047] Step 4: put the quenched and tempered signal plate body into the bluing treatment solution, and keep it warm at 135-145°C for 60 minutes to obtain the signal plate body that has undergone quenching and tempering and bluing treatment; the bluing treatment solution contains hydrogen oxidation An aqueous solution of sodium, sodium nitrite, and sodium nitrate, wherein the concentration of sodium hydroxide is 17mol / L, the concentration of sodium nitrite is 2mol / L, and the concentration of sodium nitrate is 0.4mol / L.

[0048] Step 5: Laser quench the edge of the signal plate body to obtain 7 induction strip...

Abstract

The invention discloses a compound signal panel. The compound signal panel comprises a signal panel body, wherein a plurality of induction bars which are obtained through laser quenching treatment are arranged at the periphery of the signal panel body, and the magnetic conductivity of the induction bars is different from that of the signal panel body. The invention aims to provide the compound signal panel which is simple in structure, small in processing difficulty and high in sensing accuracy and meanwhile, the invention discloses a preparation method for the compound signal panel.

Description

technical field [0001] The invention relates to the field of electronically controlled engine signal boards, in particular to a composite signal board and a preparation method thereof. Background technique [0002] In order to correctly determine the cylinder and obtain the correct crankshaft position information, the electronically controlled engine needs to use the signal plate. [0003] pass figure 1 It can be seen that most of the existing signal discs 11 detect the rotation by sensing and detecting the root fillets of the signal teeth 12 . [0004] Chinese patent CN201620184171.9 also discloses a combined signal disc, which realizes signal detection through a toothed ring structure. [0005] The problem with the existing design is that it requires high processing precision of the signal teeth and high processing cost. Contents of the invention [0006] The object of the present invention is to provide a compound signal disc with simple structure, low processing dif...
