How to prevent deformation during slow wire processing

 Slow-moving wire processing is a very exquisite and exquisite craft, and sufficient preparations need to be made, so that the processed products can be more quality. The slow-moving wire processing technology has a wide range of applications and is a must in our industries. If you want to do better with less technology, you must master all aspects of the processing knowledge. For example, the most common thing is the deformation during processing.  How can we solve it How to prevent deformation during slow wire processing Speaking of slow wire processing, it uses continuously moving fine metal wires as electrodes. Pulse spark discharge is performed on the workpiece, where it generates a high temperature above 6000 degrees. Moreover, if it wants to improve its quality problems and prevent its deformation, it can firstly start from the following aspects. 1. To prevent deformation, it is impossible for the material to have no internal stress. In particular, the internal stress of the que

KOVAR parts seal preparation and physical properties

Kovar® is a vacuum-melted iron-nickel-cobalt low-expansion alloy. The chemical composition content is controlled in a very narrow range to ensure accurate and balanced thermal expansion performance. At the same time, strict quality control during the manufacturing process of KOVAR machining parts also ensures balance Its physical and mechanical properties are more suitable for deep drawing, stamping and various cutting processes. Material use Kovar® is used for vacuum sealing of hard glass and ceramics, and is widely used in electron tubes, microwave tubes, transistors and diodes. On integrated circuits, it is used for flat integrated circuits and dual in-line packages. Seal preparation All parts made by Kovar® should be degassed and annealed in a wet hydrogen atmosphere. Hydrogen is injected into water at room temperature and gets wet through blisters. Care must be taken to prevent surface carbonization. The heat treatment furnace must have a cooling chamber that provides the same a

What are the rules for metal stamping die scrap tube?

The Purpose Standardize the management of the scrapping of the company's metal stamping dies, prevent the loss of company assets, and formulate this system specially. Scope of application It is suitable for the management of the company's scrap molds. Definition If the molds listed in the assets of the company fall under one of the following circumstances, the use management department may apply for scrapping. 1. Molds that exceed the specified service life. 2. The mold is severely damaged by accidents or accidents, and molds that cannot be repaired or have no repair value. 3. Metal stamping dies that have not reached the service life, but due to safety, quality, efficiency and other issues, the repair still fails to meet the minimum requirements of the customer's product process or affects the production safety and efficiency. 4. Product customers have stopped placing orders or have not placed orders for molds in several years. 4. Responsibilities 1. Responsibilities of th

What is the principle of a power transmitter?

The power transmitter is a combination of multiple precision parts and requires careful use and maintenance. Before using a power transmitter, you need to know its principle.

What is the principle of a power transmitter? Introduction to the principle and characteristics of power transmitters

Principle of power transmitter

transmitter
transmitter

The power transmitter is mainly composed of three-phase isolated sampling circuit, A/D converter, single chip microcomputer, DSP device, D/A converter, calibration amplifier and special thick film integrated V/I converter.

After the three-phase AC input signal passes through the three-phase isolation sampling circuit, the common ground tracking voltage signal of the three-phase current and the three-phase voltage signal is formed. Under the control of the single-chip microcomputer, the A/D converter performs multi-point synchronous sampling on it, and the sample is obtained The data is calculated by the DSP device according to the principle of electrical engineering to calculate the three-phase active power (digital quantity) of the measured signal, and then the digital signal representing the three-phase power is converted into an analog quantity by the D/A converter, which is amplified and calibrated by the calibration amplifier Then, a direct current voltage output VZ is formed; the VZ output is passed through a dedicated thick film integrated V/I converter to form a 0-20mA or 4-20mA direct current output IZ.

Performance characteristics of power transmitter

As a professional instrument salesperson, you must be familiar with the characteristics of power transmitters and be more professional when communicating with customers.

The three ports of analog output, input, output, and power supply are isolated from each other.

Good linearity and high precision.

Automatic zero calibration and excellent temperature characteristics ensure the long-term stability of the instrument and avoid the need for periodic calibration of the transmitter.

All parameters are digitally calibrated. The analog adjustment of the conventional potentiometer is abandoned, the hardware circuit is simplified, and the reliability and stability of the whole machine are improved.

Perfect electromagnetic compatibility design, with strong anti-electromagnetic interference ability.

Full use of SMT devices, so that the product has the advantages of small size, low power consumption, and light weight.

Digital output

The input is isolated from the power supply and the output. For power transmitters using optical fiber transmission, the optical fiber not only plays a transmission role, but also plays a role in isolation. It can completely avoid the loss and interference of the transmission link, and is suitable for high-precision measurement in various complex electromagnetic environments;

The digital output transmitter is convenient for networked and intelligent applications.

The digital output power transmitter can form a virtual instrument together with the transmission system and the host computer. The function and display mode of the virtual instrument are determined by the software, which can realize multi-parameter values, meters, real-time waveforms, trend curves, and bar graphs. , Pie chart, vector diagram and so on.
