Diaphragm coupling group and coupling plastic melt supplement

Published: 2018-04-20

The diaphragm coupling consists of one or several groups of stainless steel diaphragms connected with two half couplings. The diaphragms are divided into connecting rod type and integral type.Diaphragm couplings are divided into two types: single diaphragm and double diaphragm.Double diaphragm couplings are divided into JMI double diaphragm couplings, JMIIJ double diaphragm couplings, JMII double diaphragm couplings, and JMIJ double diaphragm couplings.The dual-diaphragm coupling is currently a domestic coupling device, which is especially suitable for connecting motors and fans to transmit torque to achieve a long wheelbase connection.The double diaphragm coupling can automatically correct the deviation of the shaft concentricity of the motor or the fan, so that the equipment runs smoothly. It is an ideal coupling for the fan and the motor.The installation is also very convenient, and the operator only needs to follow the operating procedures to install it correctly.

The plastic melt filling process of the coupling is also the expansion stage completed in the closed mold, which is the same as the standard injection molding method.Probably, the clamping force of the mold is gradually decreasing, and the screw is opened to a limited and repeatable position.The achievable accuracy of this position control is a key factor for the production of parts with reproducible wall thickness.The compression process moves the compression core of the mold to the compression position.When this position is reached, the compression process begins and the replenishment process is immediately stopped.Flexible coupling

Coupling expansion compression molding and injection-compression molding can change the compression ratio by using the core of the compression mold instead of the rigid clamping unit.However, the compression process is probably only accomplished by the core.The hydraulic draw rod clamping unit provides users with a mobile choice.However, this only makes sense in an environment where the coupling sector is compressed.Rely on the point of view of injection molding machine clamping unit.

Since it cannot be marked on its surface, it is in the process of injection molding optical parts.Therefore, the measurement of cavity pressure is limited.But in order to use this tight process parameter to monitor the quality of the coupling, people have adopted a non-contact measurement method using a special measurement pin to measure the cavity pressure.Couple the flow path to the diagram to open up new processing supervision skills.

On the contrary, quality optical components are not included here.It just so happens that only a high level of quality can be used to produce optical components for practical applications.As far as the prism is concerned, not only its number of shapes and surface layout play a tense role, but the repeatability of production will also greatly affect the internal performance of the product such as internal stress or molecular orientation.Therefore, for a specific example, to evaluate the optical performance of the product during the production process of the coupling, it is not enough to check the shape of the part, or to check the surface of the part with the naked eye, and to perform the optical performance measurement becomes a tension.For example, the distortion of the wavefront measured by the sensor can be used as an identification result.It can be deduced from mathematics as a tense mass function.The expansion-compression molding realized by the clamping unit is suitable for the production of parts with a stable wall thickness at the cross section.The advantage of this processing method is that stress is not introduced into the produced parts after supplementary molding, because the pressure in the injection process is not applied by the screw but by the clamping, so the pressure in the cavity is symmetrical In addition, the plastic melt can be cooled almost without stress, resulting in a part with a well-balanced micro-layout.
