Description

Technical Field

[0001] The utility model relates to the technical field of metal fittings processing, and more specifically, to a metal fittings processing die. Background Art

[0002] In the modern metal processing industry, the forming and manufacturing of metal accessories are inseparable from various precision molds. These molds exert pressure and deformation on metal accessories through the precise matching of the upper and lower modules, thereby realizing the forming of accessories. However, there are still some deficiencies in the design and use of existing metal accessories processing molds, which affect the improvement of processing quality and production efficiency. First, the existing metal accessories processing molds lack necessary auxiliary mechanisms between the upper and lower modules. In the actual processing process, when the upper and lower modules are molded and pressure is applied to the metal accessories, adhesion is easy to occur between the surface of the accessories and the mold. This adhesion is mainly due to the following reasons: Due to the friction and adsorption between the metal material and the mold surface, when the upper module rises and separates from the lower module, the metal accessories adhered to the lower surface of the upper module will be lifted up, causing the accessories to deform or be damaged, affecting product quality and pass rate. In order to prevent this adhesion phenomenon from occurring, operators usually need to pre-spray a layer of lubricating oil on the surface of the metal accessories to reduce the friction and adsorption between the accessories and the mold. However, many processing molds are not equipped with special lubricating oil spraying devices and need to be sprayed manually, which is not only inefficient, but also prone to omissions, resulting in damage to the workpiece, making it difficult to meet the needs of mass production.

[0003] Secondly, during the use of metal accessories processing molds, it is often necessary to install, disassemble and replace the upper and lower modules to meet the production needs of accessories of different models and specifications. However, existing molds have many inconveniences in module installation and disassembly. Some molds are connected by bolts and require special wrenches and other tools for assembly and disassembly, which is cumbersome, time-consuming and labor-intensive. Although other molds use other structures, they require a larger disassembly force during disassembly, and the operation is not light and flexible enough. This not only increases the mold change time and affects the production rhythm, but also brings unnecessary labor burden to the operators and increases the labor intensity.

[0004] In addition, in the process of metal accessories processing, stamping and shearing and other processes will generate a large amount of waste and scraps. These wastes fall from the gap between the upper module and the lower module and need to be collected and cleaned in time to avoid affecting the normal operation of the equipment and product quality. Existing processing molds usually use waste slides and external collection boxes to collect the fallen waste. The waste slide is tilted at the bottom of the mold to guide the fallen waste into the collection box. However, this collection method has some problems. When the waste slides from the higher slide, it will produce a large impact force on the collection box below, causing the collection box to move or overturn, which not only affects the effective collection of the waste, but also may cause the waste to scatter, affecting the workshop environment and safety.
