10 Essential Tools for Cold Forging Press

图片
The cold forging press is mainly composed of the main machine, power system and control system. Following are 10 essential tools for cold forging press. Mold The mold is one of the most critical tools of cold forging press. It determines the shape and size of the cold forged product. The cold forging mold is generally composed of an upper and lower mold, the upper mold is fixed on the slide of the hydraulic press, and the lower mold is installed on the workbench. The material of the mold needs to have high hardness, high strength and good wear resistance, such as mold steel such as Cr12MoV and H13. According to different product shapes, there are various types of molds, such as punching dies, extrusion dies, upsetting dies, etc. For example, when producing automobile half-axles, a specially designed extrusion die is required to gradually deform the half-axle blank in the mold cavity and finally form it.

Cold forging hydraulic press is a widely used equipment in metal processing and other fields. It has the following 7 benefits. Benefits of Using a Cold Forging Hydraulic Press High-precision forming Cold forging hydraulic press can achieve high-precision part forming during the processing process. Because it adopts a hydraulic drive system, the pressure can be precisely controlled, so that the metal material can be cold forged in the mold according to the preset shape. For example, when producing automotive parts such as connecting rods, the dimensional accuracy of the connecting rod can be accurately controlled, and its dimensional tolerance can be controlled within a very small range, generally reaching ±0.05mm or even higher accuracy. This helps to improve product quality and reduce subsequent processing steps. High material utilization rate The cold forging process itself has the characteristics of high material utilization rate, and the cold forging hydraulic press can gi...

Maintenance Tips for Deep Drawing Hydraulic Presses

Maintenance of the deep drawing hydraulic press is crucial. Following are some maintenance tips for deep drawing hydraulic press. 1. Daily maintenance ● Cleaning work After each use, the work surface, mold and body of the stretching hydraulic press should be cleaned in time. Because during the stretching process, impurities such as metal debris and oil stains may remain. For example, when stretching metal sheets, the debris on the cutting edge is easy to fall on the workbench. If it is not cleaned, it may scratch the mold or affect the accuracy of the next stretching. You can use a clean rag to wipe the workbench and mold. For oil stains that are difficult to remove, you can use a special metal cleaning agent. Clean the cooling system of the hydraulic press regularly. If it is a water-cooled hydraulic press, impurities in the water may scale in the cooling pipe, affecting the heat dissipation effect. Generally, check the water quality in the cooling water tank every once in a while ...

Setting Up a Deep Drawing Hydraulic Press

The setup of a deep drawing hydraulic press involves several important steps, and the following is a detailed description: 1. Preparation before installation and commissioning Site preparation Deep drawing hydraulic presses are usually heavy and need to be installed on a solid, flat ground. Make sure that the ground bearing capacity of the installation site can meet the weight requirements of the hydraulic press to avoid tilting or damage to the equipment due to ground subsidence and other problems during work. Setting Up a Deep Drawing Hydraulic Press At the same time, there should be enough space around the site to facilitate operators to operate, maintain, and transport raw materials and finished products. Generally speaking, at least 1-2 meters of space should be left around the hydraulic press. Equipment inspection Before installation, a comprehensive inspection of the deep drawing hydraulic press is required. Check whether the appearance of the hydraulic press has any bum...

How to Adjustable Speed Of Hydraulic Press

Following are the main methods about how to adjustable the speed of hydraulic press. Adjusting the flow of hydraulic pump ● Variable pump adjustment: If the hydraulic press adopts variable pump oil supply system, the displacement of the pump can be directly adjusted to control the flow. For example, for axial piston variable pump, the output flow of the pump can be changed by changing the inclination angle of the swash plate. When the inclination angle of the swash plate increases, the displacement of the pump increases, the oil flow entering the hydraulic cylinder increases, and the working speed of the hydraulic press will increase; conversely, the inclination angle of the swash plate decreases and the speed slows down. This adjustment method has high accuracy and can achieve stepless speed regulation in a large range. ● Dosing pump with flow control valve: For hydraulic presses supplied by dosing pumps, flow control valves such as throttle valves and speed control valves are us...

Hydraulic Press: Relationship Between Working Pressure, Size and Weight

图片
Following are relationships between the working pressure, size and weight of a hydraulic press. 1. The impact of working pressure on the structural size of the fuselage • Frame size The greater the working pressure of the hydraulic press, the greater the stress on the fuselage frame. In order to ensure that the fuselage can withstand these stresses without deformation or damage, the size of the frame needs to be increased accordingly. For example, large hydraulic presses with high pressure usually use thicker columns and wider beams to enhance the stability and strength of the overall structure. Large hydraulic presses above 10,000 tons have much larger column diameters and beam thicknesses than ordinary small hydraulic presses. • Cylinder size The working cylinder is a key component for generating hydraulic pressure. An increase in working pressure will increase the pressure inside the working cylinder. According to the pressure formula, when the force is constant, the pressure is i...
