Shearer pick and roadheader pick are one of the vulnerable parts in coal mining and roadway tunneling machinery, and their mechanical properties directly affect the efficiency of coal mining. Therefore, the production and manufacturing process of the cutting tooth of the roadheader coal machine and the cutting tooth production equipment are very important. Usually according to the material of the pick, there are many production and manufacturing processes. At present, in order to provide its service life, hot extrusion (hot forging) is mostly used for processing and forming, and then heat treatment, etc., the roadheader produced by this method The coal machine has a long service life and high production efficiency.
那么，掘进机煤机截齿用什么机器设备生产呢？根据其生产工艺，在热挤压成型工艺中，选用金属热挤压液压机会更适合，常用500吨、630吨、800吨等四柱液压机。可随客户需要自行调整冲压行程限位高度。顶缸顶出力和压边力（可实现锻压及拉伸）可调。采用大直径、内插控制阀、通油能力强、流量大、压力损失小、可靠性高；630吨煤机截齿热挤压液压机-掘进机截齿热锻成型设备采用双速方式，主缸采用活塞机母缸结构，主缸嵌入子缸，横截面积小，可促进主缸在油量少的情况下快速降低。当主缸接近产品时，子缸停止工作，母缸快速成型，空载功耗低，锁模快，功耗低可快速加深；配备智能感知系统、自适应模式，可实现单电机双系统、单电机单系统、双电机双系统、多系统等双速快速控制模式；
630-ton coal machine pick hot extrusion hydraulic press-roadheader pick hot forging forming equipmentThe forging process is:
Feeding (cold shearing on bar shearing machine or punching machine) → heating (initial forging temperature is 1200 ℃)→ extrusion molding (630 ton four-column hydraulic press) → post-treatment. Bar stock → cutting breaking → hot extrusion blank → rough machining → solution treatment → mechanical property inspection → finishing forming
The principle of 630 tons four-column hydraulic press hot extrusion roadheader coal cutter:
630-ton coal machine pick hot extrusion hydraulic press-roadheader pick hot forging forming equipmentThe work is mainly achieved through hydraulic transmission. Hydraulic transmission is the use of liquid pressure to transmit power and control a transmission. The hydraulic device is composed of hydraulic pumps, hydraulic cylinders (hydraulic motors and other actuators), hydraulic control valves and hydraulic auxiliary components.
Hydraulic pump: A conversion device that converts mechanical energy into hydraulic energy.
Hydraulic cylinders (actuators such as hydraulic motors): convert hydraulic energy into mechanical energy.
Control valve: control the flow of hydraulic oil, flow direction, pressure, hydraulic actuator working sequence and protection of the hydraulic circuit. The popular point is to control and adjust the flow direction, pressure and flow of the hydraulic medium, so as to control the movement direction of the actuator, the output force or torque, the movement speed, the action sequence, and limit and adjust the working pressure of the hydraulic system to prevent Overload and other functions (such as check valve, reversing valve, overflow valve, pressure reducing valve, sequence valve, throttle valve, speed control valve, etc.).
