What is the relationship between the production efficiency of the extruder

What is the relationship between the production efficiency of the extruder

Because at the lower end of the extruder slide plate, the upper hydraulic cylinder is fixedly installed on the upper hydraulic cylinder fixing plate, the piston rod extends vertically downward and is connected with the slide plate, and the die base of the continuous extruder die used in it is detachably connected Multiple inserts, the ferrule is formed with extruded metal ingots passing through, the current extruder equipment has the following advantages and effects, the ferrule is installed in the mounting hole of the die base with an interference fit, and the When the blank needs to be processed, for different types of profiles, the core can be directly replaced without replacing the entire mold, which is easy to use and can improve production efficiency. The currently used extruder pressure pad device includes a collection box with a feeding port, and also includes a feeding mechanism, a buffer mechanism, a feeding mechanism and a conveying mechanism. The current extruder equipment has the following advantages and effects. The current extrusion The press equipment adopts a new mechanical structure to enter the pressure pad in the collection box, which can be pushed to the lifting platform through the pressure pad, and then raised to the loading track through the lifting platform, which realizes the automatic feeding of the pressure pad, which is easy to use and can improve work efficiency. .

How the new extruder ensures stability

How the new extruder ensures stability

The advantage of the current new type of extruder is that, by rotating the adjustment rod, the gap between the upper and lower traction components can be quickly adjusted to adapt to the traction force of pipes with different diameters, the operation is simple, the traction wheel is avoided, and the welding efficiency is greatly improved. The working efficiency, the pressure fluctuation reduction method of today's hydraulic system extruder, the pressure oil output of the hydraulic system first enters the pulsation damper through the hydraulic pump assembly, and the noise transmitted from the hydraulic pump assembly is filtered, the pulsation damper and At the same time, the pressure oil is output, and the peaks and valleys are filtered and compressed. Due to the fluctuating pressure output by the hydraulic pump unit of the extruder, the valve block is then transmitted from the entire body to the hydraulic cylinder through the hydraulic cylinder, and the control valve block controls the actions related to extrusion, which fundamentally overcomes the pressure fluctuation caused by the rotation of the oil pump. , to ensure the smoothness of the output, thereby reducing the impact on the hydraulic components, improving the service life and stability of the hydraulic components, and improving the extrusion force of the extruder, as well as the stability and reliability of the extrusion speed control.

Extrusion process and extrusion characteristics of aluminum alloy extruder

Extrusion process and extrusion characteristics of aluminum alloy extruder

Compared with other methods, and many metals will be plastically processed during the cutting process, due to the wide range of aluminum alloy extrusion molding, an extrusion press can be used in particular, and the effect can be an ordinary crank press or hydraulic press. , friction press and high-speed hammer equipment, its aluminum alloy extrusion process has many characteristics, mainly from the perspective of stress and deformation state during extrusion, metal flow behavior, comprehensive product quality, variety and production flexibility. Of course, users must also understand the defects of extruding aluminum alloy profiles, which will enable users to better improve the extrusion process of aluminum alloys, so that the quality of aluminum alloy profiles can be improved. Among them, seamless steel pipes and seamless The production process of aluminum tubes is usually perforated extrusion, and traditional aluminum extrusion dies are usually used in combination, especially to control the temperature, while ensuring that the rod extrusion and the die are kept clean, the aging time and temperature depend on the thickness from the wall to the diameter of the aluminum sheet. thickness of.

How to improve the production quality of extrusion press

How to improve the production quality of extrusion press

Due to the high hardness of the die material used in the extrusion of aluminum profiles, when the extruder die begins to rough, the tool should be a carbide tool, and the allowance should be maintained during cutting, so as to have the choice of finishing, pay attention to the speed and chip breaker Reasonable combination to achieve chip breaking effect, milling machine is used to process die core and shunt hole of extrusion die of extruder, tool milling cutter is used to process die core and shunt hole in one step, the intersection of die core root and shunt hole plane The connection is smooth and the surface is smooth, which eliminates the stress concentration point of the machined surface and enhances the deformation resistance of the mold. Usually, the extruder uses extrusion dies and models to improve accuracy. When the lower die hole is processed by wire cutting, the cutting process should be stable to prevent the lower die from being interrupted due to cutting. The transition is not smooth, and the extrusion die for the extrusion machine is manufactured After that, heat treatment is required to improve toughness, carbon powder is usually used to protect the aluminum profile and put it into a heating box for heating, and the corresponding work is done by the equipment.

What should be paid attention to in the use of industrial extruders

What should be paid attention to in the use of industrial extruders

When using an industrial extruder, you should first check the conveyor belt, cooling bed, storage table, etc., whether the auxiliary equipment is damaged or scratched, which is the basis for ensuring the integrity of the surface of the aluminum profile. The shape of the profile is determined. For large-section hollow profiles, a tensile pad can be inserted, but a sufficient clamping area should be ensured as much as possible. In addition, the length of the aluminum profile should be determined before stretching, and then the stretching rate should be preset to determine Drawing length, usually, when the aluminum profile is cooled to below 50°C, an industrial extruder can be used to draw the profile. However, when the profile has both bending and twisting, the twisting and stretch bending should be corrected first, and only after the profile has returned to good condition, so that the processing of the equipment can continue. For industrial extruders, to confirm the intended tension Whether the elongation rate and clamping method are suitable, at the same time, it is necessary to visually check the plane gap, flaring and parallel opening of the profile. If it is not suitable, the stretching ratio should be adjusted appropriately.
