What...

The RED PUNCH presses are automatic forging presses that integrate bar stock loading, preheating in an electric or gas furnace, and automatic loading and unloading of finished parts without burrs into the process. These automatic molding equipment are managed by a highly integrated CNC system specially designed for flexible production of copper products in various shapes.The entire system includes an automatic loading facility, a medium-frequency heating furnace, an automatic temperature detection station for the bar stock, and hydraulic molding and forming equipment.

Furthermore, the equipment is equipped with a device that automatically conveys the stock material to the molding equipment and an automatic extraction device to achieve a high level of automation for the entire production process.

Through the stamping process, a flash-free forged component is obtained, reducing the amount of material used in the stock. This leads to significant cost savings. The equipment boasts high efficiency, energy-saving capabilities, environmental protection, and exceptional quality.

This set of equipment, controlled by CNC, features four independent hydraulic punching or drilling operations. Depending on the demand or requirements, the punching speed can be adjusted timely during the production process, allowing the plastic material inside the mold to move and deform according to the desired project characteristics.

This enables the production of forged parts with the maximum number of cavities possible, capable of creating a variety of hollow and complex shapes such as tees, elbows, and more. One, two, three, or four punches or drills can be selected based on the production and requirements of different products. Simultaneously, it is equipped with a 20-head adjustable lubrication system suitable for various molds.

The design concept of this machine is economical, environmentally friendly, compact, and produces minimal pollution during the production process, with noise levels below 85 decibels.

Automatic Bar Stock Feeding System

Dependent on the diameter size of the copper bar (from 14 to 35 mm).

Copper bar length: 80-120.

Automatic detection of the last copper bar. Independent medium-frequency heating device.

Stand-alone temperature control system. Before material extraction, an optical pyrometer detects the temperature and automatically rejects unqualified copper bars.

Hydraulic System

The hydraulic power system includes a 55 kW motor and 2 variable displacement oil pumps. It utilizes a dedicated proportional solenoid manifold.

Water Circulation Cooling System: 1200-liter hydraulic tank.

Dedicated proportional solenoid manifold.

Hydraulic Cylinder: 4 hydraulically controlled proportional valves with acceleration. Automatic control of flow and pressure. Independent control of each core extraction with a precision of 1/100th of a second. 4 hydraulic cylinders to control the entry and exit speeds, ensuring precise movements of the 4 punches.

Hydraulic Locking System

The system includes pressure control for relatively fast mold closure and additional locking pressure control after the upper and lower molds are closed to ensure a tight mold fit. The closing system is hydraulically driven by a butterfly valve. The height is automatically adjusted when the upper mold rises and descends. A special cylinder for removing the finished product is located above the upper mold.

Mold Support System

Standard ZG250/4G60 mold.
Mold size: 205mmx205mmx60mm.
The upper and lower mold support systems can be quickly and easily replaced.
The mold system consists of 16-point graphite injection systems, each of which can be independently controlled and can be selected from the following lubrication methods:

– Air-free/Graphite-free

– Air/Graphite-free

– Air and Graphite

Automatic Mold Lubrication Device

Adjustable lubricant dosage.

Spray duration can be adjusted.

The molded part remains in the upper mold and then falls into the finished product extractor, delivered directly to the finished product output. The machine is equipped with a special weight sensor during finished product extraction.

Electronic Control System

The electronic control system consists of a 12-inch touchscreen for programming, monitoring, and control. The integrated system is comprehensive, and the touchscreen is located at the front of the device. Machine power supply: 380V + N ground. Integrated Siemens or Mitsubishi industrial operating system. Language: Chinese/English.

Punch Displacement System

The punch displacement control system is used to read information about the punch’s distance and displacement. The system provides the final position of the punch after each stamping. It can be used to confirm that the punch has completed the stamping based on the preset position. If the final position of the punch is outside the preset tolerance range, the system issues an alarm. The system can be used to adjust the initial position of the punch. It provides a graphical representation of time versus distance. The device requires 3 parts, each for reading data from the three punches.
