Milling Machine Processing of Prototype Stamping Dies
- Milling Machine Processing
Milling machines have played a significant role in the manufacturing of prototype stamping dies. If milling processing is required, the main die components of the milling machine include a die seat, template, slider, and concave-convex film. There are many types of milling machines, which can be divided into the following types according to their structure:
1.Desktop Milling Machine: This is a small processing equipment mainly used for milling small-sized workpieces such as instruments and meters.
2.Gantry Milling Machine: The bed is arranged horizontally, and the gantry is a milling machine composed of two parts: columns on both sides and connecting beams. The milling head is placed on the column and crossbeam, and its position changes with the guide rail. In general, the position of the crossbeam changes according to the vertical direction of the column guide rail, and the workbench can move longitudinally along the bed guide rail, which is commonly used on large-sized workpieces.
3.Lift Table Milling Machine: This is a type of milling machine with a lift table that changes its position vertically along the bed guide rail. The workbench and saddle installed on the lift table usually have two types of movement, including longitudinal and transverse movements.
4.Rocker Arm Milling Machine: Rocker arm milling machine can also be called turret milling machine, rocker arm milling, or universal milling. Turret milling machine of a machine tool is a machine tool that uses metal materials for cutting and has two functions, such as end milling and horizontal milling. Usually, this type of equipment is used for milling small-sized machined parts.
5.Specialized Milling Machine: Tool milling machine, which is a type of milling machine used for milling tool dies. It has the characteristics of high accuracy and is suitable for manufacturing complex-shaped machining parts.
- Maintenance Methods for Milling Machines
The maintenance of milling machines mainly includes the following aspects: the overall equipment should be cleaned comprehensively, and the surrounding environment must be clean and tidy; Ensure that each oil level is in compliance with the standard cursor and apply lubricating oil to each part.
1.Cleaning：Clean each oil felt pad and wipe each component. When wiping, employees should not leave any dead corners.
2.Apply lubrication：The operator applies lubricating oil to the oil hole, sliding surface, and oil tank body to ensure that these components meet the requirements.
3.Tightening：The operator checks the tool transmission mechanism, pressure plate, screws, and other components. If any loose screws are found, employees should tighten the loose screws promptly to avoid problems.
4.Adjustment：Carefully inspect the pressure plate and slider, and if any parts become loose, employees should adjust them promptly.
5.Maintenance：To prevent rusting of the equipment, it is necessary to remove the rusted parts, which helps to protect the surface of the equipment. Apply oil to surfaces that are prone to rusting to prevent corrosion.
Grinding Machine Processing of Prototype Stamping Dies
There are many types of grinders, which can generally be divided into inner or outer cylindrical grinders, surface grinders, forming grinders, tool edge grinders, tool grinders, coordinate grinders, and many specialized grinders. They are machine tools that use manufacturing tools such as grinding wheels, oilstones, abrasives, and abrasive belts to cut and process product components.
The gradual development of grinding machines is due to the need for precision machining and hard surface machining, and currently, there are also a few high-efficiency grinding machines used for rough machining. Grinding machines can manufacture various surfaces, including inner and outer cylindrical and conical surfaces, flat surfaces, involute tooth profiles, helical surfaces, and various forming surfaces. They can also sharpen cutting tools and perform cutting. The manufacturing process of grinding machines is applied to many products.
prototype stamping dies to meet the surface, workpiece shape, and manufacturing requirements of various components for grinding die components. The processing range of various grinding machines commonly used for grinding die components may also vary.
A surface grinder is mainly used for grinding template surfaces and mold surface parts. Surface grinding machines can be divided into several types, such as vertical axis rectangular table surface grinding machines, horizontal axis rectangular table surface grinding machines, vertical axis circular table surface grinding machines, etc. The spindle of a surface grinder is divided into two types: vertical axis and horizontal axis. One type is a vertical-axis rectangular table flat grinding machine, which is mainly composed of a grinding wheel frame, a column, a sliding saddle, a workbench, a bed body, and a bed saddle. Another type is a horizontal-axis rectangular table surface grinder, which mainly consists of a grinding wheel frame, a column, a workbench, a bed body, and a bed saddle.
Except for the vertical axis rectangular table surface grinder and the horizontal axis rectangular table surface grinder. The workbench is also divided into two types: rectangular and circular, respectively called horizontal axis rectangular table surface grinder and vertical axis circular table surface grinder. Unlike other grinding machines, the workbench is equipped with electromagnetic suction cups, which directly suck on the workpiece and workpiece fixture through tools.
During the machining process, the main operation is the rotational motion of the grinding wheel, and the longitudinal feed motion is the linear motion of the workpiece provided by the worktable. The grinding amount for flat grinding is composed of the transverse feed motion, vertical feed motion, and longitudinal feed motion of the grinding wheel. The key points for using a grinding machine for high-speed stamping molds are as follows.
1.When grinding important parts flat, the operating technique should specify that they are ground parallel. If it is necessary to specify the operating technique for thin parts and reverse grinding flat surfaces, attention should be paid to parallelism or to prevent shape changes.
2.Technicians will increase the flat grinding process, including workpieces that are prone to shape changes after milling, as well as sheet-shaped parts cut by planers and lathe workers. If heat treatment is required, the joint surface of the cobalt hole needs to be machined before this operation. Generally, the joint surface should be leveled before drilling.
3.Flat grinding is suitable for grinding large workpieces that have undergone mechanical processing. The purpose is to perform precision or semi-precision machining on the plane of the workpiece. If the plane of the workpiece is too small and it is unreliable to rely solely on the electromagnetic table for suction and fixation, reinforcement measures should be taken, such as placing iron pads next to the workpiece to ensure stable and reliable positioning before processing.
4.In general, the flat grinding process involves directly writing down the size of the ground material. This dimension is the sum of the maximum size of the workpiece and the subsequent grinding amounts. It can be written as polished six faces or polished two faces, but it must be in a situation where the process does not require further grinding or the size requirements after flat grinding are not strict.
5.Generally, parts with six sides at right angles will be used, and the technical specifications should specify that they are ground to a right angle.
