Embodiment

[0015] like figure 1 , 2 1. The manufacturing process of an electronic heater for an electronic thermostat shown in 3. First select a hollow tube with a diameter of 3 mm, cut the hollow tube into 100 mm by a cutting machine, and process the lower end of the cut hollow tube through a Baotou machine Form a cold-extruded Baotou, and then use an ultrasonic cleaning machine to clean the oil inside and outside the hollow tube; select a round steel with a diameter of 12mm and a length of 12mm, and form a circular step on the outer diameter of the car, and the horizontal width of the circular step gap is 2mm, and then drill the hole. The inner diameter is 3mm, that is, the diameter of the through hole formed by the inner circle step of the round steel is 3mm, and the hole is expanded again. Then cut off the lower part of the round steel by 2mm, so that the bottom of the finished product is smoother and flatter. Next, the hollow tube is pressed into the round steel to make close conta...

Abstract

The invention relates to the field of automobile accessories, in particular to an electronic heater manufacturing process for an electronic temperature regulator. The electronic heater manufacturing process for the electronic temperature regulator includes the steps: firstly, selecting a hollow pipe with the diameter of 2mm-5mm, cutting the hollow pipe to be 80mm-120mm by the aid of a cutting machine, machining the lower end of the cut hollow pipe to form a cold extruding tip by the aid of a tipping machine, and then cleaning greasy dirt inside and outside the hollow pipe by the aid of an ultrasonic cleaning machine; secondly, selecting round steel with the diameter of 6mm-16mm and the length of 10mm-20mm, turning the outer circumference to form a circular step, drilling a through hole, expanding a hole to form an inner circular step, and pressing the hollow pipe into the round steel. The inner diameter of the through hole is equal to that of the hollow pipe, the diameter of the expanded hole is equal to the outer diameter of the hollow pipe, the length of the expanded hole is equal to the press-in length of the hollow pipe, and the hollow pipe closely contacts with the inner circular step. The electronic heater manufacturing process has the advantages that the manufacturing process is simplified, raw materials are saved, and an electronic heater is high-temperature resistant, insulated, fast in heat conduction and short in response time.

Description

technical field [0001] The invention relates to the field of auto parts, in particular to a manufacturing process of an electronic heater for an electronic thermostat. Background technique [0002] The electronic thermostat can automatically control the valve to automatically change the flow of the liquid according to the temperature change of the liquid and the working condition of the engine, so that the engine can reach the best working condition. High-end products are beyond the reach of traditional mechanical thermostats. The core of the electronic thermostat automatic control valve is the heating element, that is, the electronic heater. Due to the limitations of the use environment and production process, the small-sized electronic heater is still blank in China, and the quality of foreign products has also been stagnant. The main The problem is short life, long warm-up time, and low sensitivity. Contents of the invention [0003] In order to solve the above-mentio...
