Precision Stamping Dies
Stamping dies are special technical equipment for processing materials (metal or non-metals) of parts (or semi-products) through cold pressing processing, which is called cold pressing dies (commonly known as cold dies). The stamping machine is a pressure processing method that uses the mold installed on the stamping machine to apply pressure to the material at room temperature to cause it to separate and plastic deform, so as to obtain the required parts.
The development of Moldbao precision stamping mold manufacturing technology is mainly reflected in:
- High-speed milling processing (spindle speed is generally 15000r/min~40000r/min, milling hardness up to 60HRC)
- EDM (equipped with automatic compensation system for electrode loss, CAD/CAM integrated system, online automatic measurement system and dynamic simulation system)
- Slow wire cutting technology processing accuracy (speed has reached 300mm2/min, processing accuracy can reach ±1.5μm)
- Grinding and polishing processing technology (with CNC forming grinder, CNC optical curve grinder, CNC continuous trajectory coordinate grinder and automatic polishing machine advanced equipment and technology)
- CNC measurement (in addition to high-precision measurement of complex surface data, the three-coordinate CNC measuring machine also has a good temperature compensation device and anti-vibration protection ability)
The stamping die should adopt a multi-station progressive die, and the carbide insert progressive die can improve the service life. In the small batch production and trial production of new products, simple molds with simple structure, fast manufacturing speed and low cost should be used, such as combination molds, thin plate molds, polyurethane rubber molds, low melting point alloy molds, zinc alloy molds, superplastic alloy molds, etc. Computer-aided design (CAD) has begun to be used for molds, which are optimized through a series of computer-centric systems. This is the development direction of mold design.
Precision stamping dies - Connectors
Introduction to plug-in mold: Precision connector refers to the connector and card slot in electronic and electrical equipment. THEY ARE SMALL (SOME ARE ONLY 0.25MM IN DIAMETER) AND ARE NUMEROUS. Therefore, the requirements for mold quality and precision are high. Molds that make products like plugs and card slots We call them precision connector molds.
Product advantages: Moldenberg has in-depth technical precipitation in precision plug-in molds, large, complex continuous type, multi-station robot automatic type, semi-automatic type, etc., which can provide customers with excellent efficient and safe mold production solutions
Application scenarios: manufacturing of cars and motorcycles, electrical appliances, IT products, office automation equipment, light industrial products, medical equipment, as well as structural and interior parts manufacturing of aircraft, ships and high-speed trains and other equipment.
Precision stamping dies - shrapnel dies
Product introduction: In the circuit is blocked or isolated circuit, build a bridge of communication, so that the current flow, so that the circuit can achieve the predetermined function. The form and structure of the connector are ever-changing,
Product advantages: precision shrapnel stamping mold in the manufacturing through forging cutting, processing and heat treatment and other processes to ensure the quality of precision shrapnel, reduce production costs, with good forgability, machinability and grinding and other materials
Applications: mobile phone cards, mobile phone antennas, headphone audio ports, plugs, micro motors, sensors, automotive instrument tact switches, medical equipment, PCB board shielding covers, etc.
Precision stamping die-terminal die
Product introduction: The terminal is the part of the battery that connects the external conductor. Electrical engineering is also called terminal block, the type is divided into single hole, double hole, socket, hook, etc., on the precision of the mold, high-speed terminal mold belongs to precision mold.
Product process: terminal mold is divided into two-dimensional mold and three-dimensional mold, terminal stamping die structure is mold base, cushion plate (punch fixing plate, stripping plate, knife edge fixing plate), punching column; Understand the mold drawing, be familiar with product information, analyze the mold structure, and understand the design intent; Check parts, chamfer, polish, engraving and mark meticulously; The template is deburred, oiled to prevent rust step by step, and special positioning tools should be used to install external guide columns and guide sleeves to ensure their verticality; The measured thickness of the template, the four-point measurement difference within 005mm is qualified; Punch, block single matching, the combination should be smooth, the grinding is measured, and the judgment standard is clear; The self-inspection of the product during mold testing and mold adjustment should use a projector, and the accuracy of the mold into the block is 0.003mm; without the concept of precision, it is impossible to cultivate high-quality, nor can it be installed with high-precision molds, mold design; mold processing; mold assembly, mold testing and repair. All three are indispensable. A set of high-precision molds should have precision design, precision processing, and precision assembly.
Applications: precision connector terminals, medical terminals, automotive terminals, mobile computer equipment, digital cameras, automotive/aviation/marine electronic components, medical electronics, smart home appliances, IC, 3C products, etc.
Precision stamping dies - cold stamping dies
Product introduction: Cold pressing molds are mostly installed on the press, which is a special special tool for applying deformation force to the placed plate at room temperature to deform it, and obtain a certain shape, size and performance of product parts.
Working principle: directly or ask the upper mold of the composition mold fixed on the upper mold, which is connected with the punch slide through the mold handle. The zero fixed on the lower mold constitutes the lower mold of the mold, and when working, the strip material is sent in and positioned by the blocking material, and the workpiece is ejected from the hole of the die by the spring force of the top block against the top plate; At the same time, the waste material clamped on the punch is unloaded by the spring of the discharge plate by the spring, and then the workpiece is taken away, so as to complete the entire blanking process.
Applications: automobiles, motorcycles, telephones, mobile phones, PCs, medical supplies IC lead frame products, etc.
