630 Ton Coal Cutter Tooth Hot Extrusion Hydraulic Press - Forging Process of Mining Machine Cutter Tooth
Coal cutter teeth and mining machine cutter teeth are vulnerable components in coal mining and tunneling machinery, and their mechanical performance directly affects the efficiency of coal mining. Therefore, the production process and equipment for manufacturing mining machine cutter teeth are crucial. Typically, various manufacturing processes are employed based on the material of the cutter teeth. Currently, to enhance their lifespan, hot extrusion (hot forging) processing is commonly utilized, followed by heat treatment. This method ensures a long service life and high production efficiency.
So, what machine equipment is used to produce mining machine cutter teeth? According to the production process, in the hot extrusion forming process, a metal hot extrusion hydraulic press is more suitable, commonly available in 500 tons, 630 tons, 800 tons, etc., as a four-column hydraulic press. The stamping stroke limit height can be adjusted according to customer needs. The ejection force and pressing force (for forging and stretching) of the top cylinder can be adjusted. It adopts a large-diameter, interpolated control valve with strong oil passage capacity, large flow, low pressure loss, and high reliability. The 630-ton coal cutter tooth hot extrusion hydraulic press - mining machine cutter tooth hot forging equipment uses a two-speed approach. The main cylinder adopts a piston machine and mother cylinder structure, with the mother cylinder embedded in the sub-cylinder. The small cross-sectional area can promote rapid descent of the main cylinder with less oil. When the main cylinder approaches the product, the sub-cylinder stops working, and the mother cylinder quickly forms, with low idle power consumption, quick mold locking, and low consumption for rapid deepening. It is equipped with an intelligent sensing system and an adaptive mode, enabling single-motor dual systems, single-motor single systems, dual-motor dual systems, multiple systems, and other two-speed fast control modes.
Forging Process of 630 Ton Coal Cutter Tooth Hot Extrusion Hydraulic Press - Mining Machine Cutter Tooth Hot Forging Equipment:
Feeding (cutting on a bar cutting bed or punching machine) → Heating (starting forging temperature is 1200℃) → Extrusion forming (630-ton four-column hydraulic press) → Post-treatment. Bar → Cutting → Hot extrusion blank → Rough machining → Solution treatment → Mechanical property testing → Precision shaping.
Principle of 630 Ton Four-Column Hydraulic Press for Hot Extrusion of Mining Machine Coal Cutter Teeth:
The operation of the 630-ton coal cutter tooth hot extrusion hydraulic press - mining machine cutter tooth hot forging equipment is mainly achieved through hydraulic transmission. Hydraulic transmission is a method of using liquid pressure to transmit power and perform control. The hydraulic device consists of a hydraulic pump, hydraulic cylinder (hydraulic motor and other executing mechanisms), hydraulic control valve, and hydraulic auxiliary components.
- Hydraulic Pump: Converts mechanical energy into hydraulic energy.
- Hydraulic Cylinder (Hydraulic Motor and Other Executing Mechanisms): Converts hydraulic energy into mechanical energy.
- Control Valve: Controls the flow, direction, and pressure of hydraulic oil, the working sequence of hydraulic executing mechanisms, and has protective functions for the hydraulic circuit. It controls and adjusts the flow direction, pressure, and flow of the hydraulic medium, thus controlling the movement direction, output force or torque, movement speed, action sequence of the executing mechanism. It also limits and adjusts the working pressure of the hydraulic system, prevents overload, and has other functions (such as one-way valve, directional valve, overflow valve, pressure reducing valve, sequence valve, throttle valve, speed control valve, etc.).
