Application Example of 1200 Ton Excavator Track Plate Die Forging Trim Hydraulic Press
Excavator track plates are often manufactured using the die forging process, and the equipment for die-forging track plates is referred to as an excavator track plate forging hydraulic press. There are various structures such as four-column and frame types. Considering the forging process steps for excavator track plates (blanking, bar heating, pre-forging, forging, punching, trimming, quenching heat treatment), three types of hydraulic presses are required for production: forging hydraulic press, trimming hydraulic press, and punching hydraulic press. Here, Nadun Machinery Manufacture Co., Ltd. introduces the application of the 1200-ton excavator track plate die-forging trim hydraulic press in actual production.
This 1200-ton excavator track plate die-forging trim hydraulic press, also known as a trimming and shaping hydraulic press, is primarily used to remove flash and excess material after the die-forging process. In the production process of track plates, the hot blanks of excavator track plates need to undergo trimming to remove excess material. This machine generally adopts a three-beam four-column structure design, incorporates advanced technology, and may utilize a PLC control system. The energy conversion, adjustment, and transportation are achieved through pumps, cylinders, and various hydraulic valves, completing the cycle of various process actions. It features an independent power mechanism and electrical system.
Process of Trimming Excavator Track Plate Die Forging with 1200 Ton Four-Column Hydraulic Press:
The hydraulic cylinder of the 1200-ton excavator track plate die-forging trim hydraulic press is plunger type, and the main cylinder is installed in the upper beam to output forging or trimming pressure. During fast trimming, the main hydraulic pump starts, establishing overall pressure in the hydraulic system. The electromagnetic directional valve obtains current, driving pressure oil into the main hydraulic cylinder. Subsequently, another electromagnetic directional valve receives current, the cartridge valve is activated, connecting two lifting cylinders and the main cylinder, causing the moving beam to move downward, forming differential trimming or forging. After the trimming process of the 1200-ton excavator track plate die-forging hydraulic press is complete, the electromagnetic directional valve receives power, and the main hydraulic cylinder, through multiple cartridge valves, enters a three-stage rapid unloading state. When the pressure in the system drops to a preset level, the electromagnetic directional valve receives power, causing pressure oil to enter the lifting cylinder. The filling valve on the main hydraulic cylinder opens, relying on the residual pressure in the lifting cylinder and the oil supply from the main hydraulic pump, allowing the moving beam to quickly move upward, completing one cycle of trimming. The 1200-ton excavator track plate die-forging trim hydraulic press then automatically enters the next cycle through pressure or stroke control, forming a fast forging and trimming cycle.
To utilize residual heat, the 1200-ton track plate die-forging trim hydraulic press needs to coordinate with the excavator track plate forging hydraulic press according to a certain production rhythm. The productivity of trimming is limited by the productivity of the forging equipment. The pressure required for hot trimming is much smaller than that for cold trimming. The material has good plasticity, and the cut is not prone to cracking but is susceptible to deformation.
Advantages of the 1200 Ton Excavator Track Plate Die-Forging Trim Hydraulic Press:
1. The 1200-ton excavator track plate die-forging trim hydraulic press adopts a four-column three-plate open design, with each column equipped with self-lubricating bearings, providing high downward stability.
2. The worktable of the equipment is large, suitable for the installation of large molds, large-area leveling, punching, bending, etc.
3. The hydraulic circuit design is simple, requiring less force from the motor. The four-column hydraulic press is easy to maintain, and the circuit design can be changed according to the user's working requirements to achieve the desired results.
4. Each table of the 1200-ton excavator track plate die-forging trim hydraulic press is equipped with a wheel seat, making it a mobile machine, labor-saving, and efficient.
5. The 1200-ton excavator track plate die-forging trim hydraulic press can be equipped with a photoelectric protector for upward and downward movement, facilitating mold adjustment, timing, and counting of downward pressure. It is convenient for adjusting pressure, speed, and stroke.
6. The four-column hydraulic press can be equipped with a rotary indexing table, automatic feeding, and return material device.
