[Introduction to Sheet Metal Processing Technology] A method for positioning half punches without exposing them on the surface.

A method for achieving a flat appearance by not allowing half punches to show on the surface.

Half punches are a machining method used for positioning during the joining of other parts. Generally, a depression is made on the surface to serve as a marker. What methods are available for positioning without compromising the appearance?

Introduction to Sheet Metal Processing Technology: Common Terms Used in Mechanical Engineering (Blanks)

Terms commonly used in mechanical engineering (blank)

**Commonly Used Terms** 'Guide Mark'... Refers to the marks created on the top or bottom surface of the workpiece by guides or strippers. Generally, if the pressing pressure is strong, a circular mark will appear, and if it is a single press, a crescent-shaped mark will appear. 'Burr'... Refers to the small curled parts that occur on the sheared edge of the workpiece. If they remain on areas that can be touched, they pose a risk of injury, so they need to be removed. 'Clearance'... Refers to the gap in the punch hole. If the clearance is excessive, twisting or deformation can occur in the punched area. Typically, a width of more than twice the thickness of steel or aluminum material, and more than four times for stainless steel, is required. 'Knockout'... A processing method where the workpiece is punched out to the thickness of the sheet, but a part is left connected to the base material. It should be designed for easy removal on-site as needed. A dedicated knockout die (usually round) is required. 'Dowel Projection'... Refers to the process of adding spherical protrusions to the workpiece. Nesting... Refers to the layout of sheet workpiece cutouts directed to NC processing machines via CAM.

[Sheet Metal Processing Example] Unloading Work of Punching and Laser (Blank) Process

In the context of processing cut materials primarily from fixed-length materials, the ingenuity to improve yield and efficiently utilize materials is becoming increasingly important.

Our blanking operations mainly involve cutting out from standard-sized materials, which requires disassembly work. By efficiently arranging the materials in order according to thickness during the CAM nesting stage, this disassembly work can be streamlined, making it easier to transition to the next bending process. Considering time shifts, we have arranged multiple operators, which has made the flow of the process smoother. Moving forward, we hope to further improve and streamline the process, including reducing material waste.

Efforts to Rationalize Nesting in Sheet Metal Processing Technology

Nesting refers to the process of cutting material parts from standard-sized materials. Improving the efficiency of nesting is an important factor in terms of cost.

At our headquarters factory, which has two combined processing machines (laser and turret punch), we are currently working on more efficient production through innovative nesting techniques. By constructing diagrams between the combined machines, we expect to significantly enhance the effectiveness of our operations. With the involvement of the design department, we can categorize sheet thicknesses and create summaries, and we will aim for production rationalization by engaging in lot production tailored to personnel and equipment.

[Questionnaire] Questions regarding metal, sheet metal, and press processing at the Jinzhang Workshop.

"Can we actually visit the manufacturing factory?" "What is the maximum size and thickness of the steel plates that can be produced?" We will answer these questions!

Since our establishment in 1964, we have been leveraging our accumulated sheet metal know-how and extensive inter-company network to build a manufacturing network that supports a hybrid-type integrated production system. 【Part of Your Questions】 1. Are you able to handle processing and press processing that involves molds? 2. How reliable is the quality? Additionally, do you take environmental considerations into account? 3. Is it possible to produce items (samples) based solely on the actual product (without drawings)? Also, if only a rough image is determined, can you support design and drawing creation? 4. What is the minimum lot quantity you can accommodate? Does the cost vary based on this? *For more details, please download the materials or contact us directly.

Initiatives as a HUB for the manufacturing network.

Our strength lies in our ability to provide one-stop services from design to sheet metal processing, painting, assembly, and delivery installation.

At Rinjō Work, we engage in transactions with various material suppliers in Osaka, component purchasing companies across the country, and numerous cooperative processing companies mainly in Higashi-Osaka and neighboring areas, in order to fully respond to the diverse requests of our customers in a one-stop manner. Among these, we have established a "manufacturing network" that enables processing methods and volume responses that cannot be handled by our company alone.

Introduction to Sheet Metal Processing Technology: Characteristics of Cell Studs

I will introduce the differences in characteristics between cell studs and stud bolts, as well as how to use them appropriately.

**Differences Between Cell Stud Method and Stud Welding** The cell stud method is significantly different from what is commonly known as stud welding. In our company, we use the CD method for stud welding, which is one of the welding methods that utilizes a capacitor charged from an AC power source. On the other hand, the cell stud method involves pressing into pre-drilled holes in the steel plate. **Advantages and Disadvantages of Stud Welding** Stud welding has minimal impact on the base material, and the surface appearance is hardly affected. It is an effective processing method when you want to maintain the appearance while incorporating the functionality of screws. However, in terms of strength stability, it lacks reliability, and there is a possibility of the studs coming off.

[Sheet Metal Fabrication Examples] Welding Assembly of Various Box Enclosures

We have abundant design and processing know-how for various types of boxes, including panel-related items, equipment boxes, machine enclosures, amusement machines, scientific instruments, and various cabinets, etc.

Our company conducts sheet metal processing for various box enclosures tailored to specific applications. This includes not only enclosures for control panels but also boxes associated with machinery, FA switch boxes, and enclosures for scientific instruments, among others, with a wide range of uses and purposes. The key to efficiently managing relatively small production units (lots) lies in personnel allocation and the selection of equipment. Our assembly department is systematically working on improving QCD through flexible personnel shifts and a rich lineup of equipment.
