Closed double crank precision punch press-Product-Dongguan Samhoor Precision Machinery Co., Ltd.

Product Introduction

Closed double crank precision punch press, samhoor's products have become high-quality machines for stamping various precision metal parts with excellent performance and stability, bed and multiple load-bearing guide pillars, including two large-sized guide pillars and four smaller-sized guide pillars.

Types of precision small hardware stamping parts stamped by Closed double crank precision punch press

Below we use the ballpoint pen commonly used in the office as a contrast and foil to explain some of the precision Closed double crank precision punch press stamping products. As shown in the figure, we can see that through the tip of the ballpoint pen, we find that the smallest stamping part is extremely small. They are mini motor stators and rotors, square cylindrical metal needles, micro connecting rods for watches, card ejection pins for mobile phone memory cards, battery button covers, metal buttons for clothing accessories, speaker mesh covers for headphones, headphone covers, copper metal lead frames, and connector terminals, etc.

precision punch press is often used for precision hardware stamping processing

To achieve conductive connections between wires and equipment machines, phosphor bronze and brass are common materials for precision terminals. The metal needle shaped like a square column has a very fine head, which has a very high requirement for precision. Therefore, the quality of stamping will greatly affect the yield rate. The gap and width between the upper and lower precision cutting heads must be accurate. At the same time, the parameter settings of the Double crank automatic feeding punch press equipment must be accurate and reasonable. The speaker mesh cover of the earphone can fix and support the earphone. The metal speaker mesh can prevent mouth spray, and the sound will not appear. It can soothe and adjust the air flow of the sound we produce when listening and speaking, and improve the sound quality.

The connecting rod and the tiny metal needle used in watches

The connecting rod and the tiny metal needle used in watches. The stamping process of this metal connecting rod is very complicated. We can see that the precision requirements for its bending are different. The surface texture requirements of the entire connecting rod are very picky. Burrs and shape accuracy violations are not allowed to appear.

Ejector for mobile phone memory card, card remover

Two oval holes and one large hole make this ejector look like a smiley face, so it is also called a smiley card ejector, a tool used to remove various machine cards. For example, the ejector used for mobile phone memory cards, the card ejector, we need to use it to push the card tray out when we take out the card in daily life, and it functions like a key.

Metal buttons for clothing

Metal buttons are not only used on clothes, but also on shoes, various fabrics, and even paper and plastic products, because they can connect two things. In addition to the connecting function, they can also be used for decoration. Metal buttons of various colors and shapes can be made to decorate various daily necessities.

Stator and rotor of stack riveting process

If we zoom in on the object and observe the details of the picture, we can clearly see that the entire stator and rotor are actually made by combining multiple metal sheets together. During the stamping process, the stamped metal sheets are constantly combined with the metal sheets that have already been stamped out, that is, the punch press is constantly doing the pressing work, not that all the metal sheets are stamped out before they are put together for pressing. This is because each metal sheet is being stamped by the punch press until the complete stator and rotor are stamped out. This is why the strength and rigidity of the stator and rotor are very high, and the metal sheets have strong adhesion under high pressure stamping.

Closed double crank precision punch press application industry type

1. The automotive industry is an important user of the high speed precision punch press industry

As one of the main equipment for stamping parts processing, Closed double crank precision punch press is widely used in the automotive industry. Due to the huge market, large demand and fast growth of the automotive industry, the demand for high speed precision punch press is also relatively high. In the past few years, China's automobile industry has maintained relatively stable development. At the same time, with the advancement of the informatization and automation process of the automobile industry, especially the rapid development of new energy vehicles, this has brought great development opportunities to the Straight column high-speed precision double crank punch press industry.

2. The electronics industry is an important growth point for the Closed double crank precision punch press industry

In the development of the electronic information industry, the demand for C-Type high speed presses as auxiliary processing equipment is also increasing. From the perspective of national policies, my country is actively promoting the industrialization of information, especially the "Made in China 2025" plan, increasing investment and support for the electronic information industry, and the application of H-Frame high speed punch presses in the electronic information industry has gradually expanded.

3. The development of the construction industry requires the support of the Closed double crank precision punch press industry

The demand for new building materials and high-end construction equipment has gradually increased, which has promoted the rapid development of the precision punch press industry. In the construction industry, the main function of high speed precision punch press is in the process of making building materials. Due to the characteristics of high efficiency, accuracy and good repeatability, Gantry type high speed stamping machine is widely used in metal doors and windows, aluminum alloy doors and windows, large glass doors and windows, steel structures and other fields.
