Reliable precision terminal connectors can ensure the stability of the operation of electrical equipment. Understand the stamping process of stamping parts, and analyze the "Direct plug-in precision terminal block connector stamping process flow" from equipment selection, mold preparation, raw material preparation, and process design.
1. Stamping equipment preparation
Choose a high-speed precision punch press, and select high-speed stamping equipment of appropriate tonnage according to the material and accuracy requirements of the stamping parts. For example, choose a high-speed precision punch with a stamping accuracy of 0.02 mm, and be equipped with an automatic feeding device to transmit terminal connector metal strips. The functions of automated operation and multi-stage feeding can significantly improve assembly efficiency and production efficiency. Intelligent digital control can realize the automation of complex processing of terminals and production processes. 45 ton open single point high speed precision press stamping terminal connector is also an option that can be considered.
2. Stamping mold preparation
Molds are the basis for product manufacturing accuracy and quality assurance. Direct plug-in precision terminal block connector stamping process flow is inseparable from the design and manufacturing of molds. When designing molds for high-speed precision terminals, the mold design of ball terminals requires certain skills. The design of this type of mold requires a relatively high technical content, but for high-speed precision terminal connector stamping, on the basis of ensuring efficiency and performance, the mold The design still pursues simplicity as possible. Measure the size, orifice, fillet radius, and rotation angle of the product to design the parts template, ejector pin, bottom pin, guide column, stopper, etc. of the mold, and finally assemble it. Many high-precision molds will choose more sophisticated stamping equipment, such as double column double crankshaft closed high-speed precision mechanical press.
3. Raw material preparation
For the stamping of precision terminal connectors, the raw materials are generally metal materials with good conductivity, corrosion resistance, flexible and reliable processability. The materials are mainly phosphor bronze, brass, beryllium copper, titanium copper, stainless steel, etc. Copper alloys with excellent electrical conductivity and tin alloys with soft texture and good welding properties are good choices. These materials have high plasticity and toughness, low yield-strength ratio and aging sensitivity. When choosing carbon steel materials, there are generally certain requirements for the elongation of carbon steel, otherwise the performance of stamped parts after stamping will be poor.
4. Stamping process design
The general process flow of high-speed precision terminal connector stamping includes busbar cutting, stamping forming, punching and forming. Specifically, punching will separate the material strip, bending the material can make the metal material have a certain angle, and stretching the material can make the metal material have a certain angle. The material becomes open and hollow, etc. Cut the busbar according to the required length, place the busbar material in the mold and stamp it with a high-speed precision punch press, and then perform single-hole and multi-hole stamping steps, or use continuous stamping to stamp the metal material strip, and finally press, Flip and wait.
In addition to what is mentioned above, there are actually many details about stamping. The design of the process will be more complete and accurate supplements from these details. Let’s briefly explain the direct plug-in precision terminal block connector stamping process flow.
