Either the equal volume method or the equal mass method can be used. Generally, the equal-mass method is more commonly used. The meter weight of aluminum material X the number of meters + residual pressure = rod weight, and the length of the rod can be determined.Extrusion length = (length of aluminum rod / upsetting coefficient - excess thickn...

For the mold pad of the extruder, the backing plate used for the transition between the mold and the machine table does not need to be too hard, but it needs to have sufficient thickness and area. If the backing plate is too hard, it will damage the working table of the machine tool. Specifically, it depends on how many tons of extruder is used...

When the pressure of the vane pump of the aluminum profile extrusion machine reaches 100, the noise is particularly loud, and there is almost no noise when the pressure is 70-80. What is the reason?The pressure of the vane pump of the extruder is generally not greater than 16MPa, and it can be between 10-14 in normal use, depending on where the...

When the aluminum profile extrusion machine cannot extrude the profile under the maximum working pressure, commonly known as stuffy car, there are many reasons for the stuffy car of the extrusion machine, such as: low temperature of aluminum rod, low temperature of extrusion cylinder, low extrusion speed , The mold temperature is low. If any of...

As for what should be paid attention to during assembly, the summary is as follows: 1. The sealing ring must be selected correctly, including type and size; 2. The assembly must be clean and not pollute the valve body; 3. The direction of the sealing ring must be correct; 4. The sealing ring when assembling, it should be placed flat, that is, i...

As for the auxiliary pump on the aluminum extrusion machine without pressure, we need to do a small check on the machine. First, determine whether the steering of the oil pump is correct; second, check the relief valve, check the oil circuit, and see if the relief valve works; finally, check whether there is any problem with the pump itself. If...

MN is a unit of force, and MN literally means "meganew" or "one million cattle". 1 trillion is 1 million. It is roughly 100 tons of force. For example: the extrusion force of a 630-ton extrusion machine is 6MN, which is a force of 6,000,000 Newtons. Of course, the larger the value, the greater the extrusion force, and the more regular the extru...

Look at the way to control the exhaust. If you use a pressure relay, you can increase it appropriately; if you use a pressure transmitter, you can modify and increase the exhaust pressure on the man-machine interface. It is mainly aimed at the extruder that used to be normal. If it is a new machine, there may be procedural problems. Suggestion:...

First of all, determine whether it is a problem with the hydraulic pump. If not, check the overflow valve and tighten the pressure adjustment handwheel. Manually turn on the overflow valve spool to see if there is any pressure, and the pressure is set at 21Mpa.

There are many systems in the aluminum profile extrusion machine. If the pressure is set, it must first be analyzed according to the hydraulic schematic diagram. Usually, the movement of the oil cylinder depends on the relationship between its power and the load. Simply put, even if there is pressure, the load is greater than The power and the ...

During the extrusion process, the extrusion force is mainly affected by deformation resistance, processing rate, ingot length, die angle, extrusion speed, friction conditions, extrusion cylinder temperature and other factors. First, determine whether there is a problem with the hydraulic pump. If not, check the relief valve and tighten the pres...

When the aluminum profile extrusion machine is running normally, due to the oxidation reaction between the surface of the high temperature aluminum ingot and the oxygen in the air, some colors of the aluminum ingot will fade. This is a normal reaction, but the profile will not fade.

When we use the aluminum extrusion machine, we will encounter power failure, so don't worry, sometimes it is due to motor overload, try to reset the electric box contactor, check the start button and power cord for failure, check the motor or other electrical accessories normally.
