hitachi power tools tools refer to implements used in woodworking. They generally have sharp cutting edges, so safety must be observed during use. Frequent sharpening is required, especially for planer blades and chisels; keeping them sharp ensures ease of use and quality, as the saying goes, "sharpening the axe does not delay the woodcutting." Woodworking tools are categorized into power tools, pneumatic tools, and hand tools. Power tools can be divided by function into multi-function tools (multi-purpose tools) and single-function tools (such as electric planers, jigsaws, circular saws, sanders, and engraving machines); pneumatic tools include polishers and nail guns; hand tools can be divided into measuring tools, hand saws, woodworking planes, wood files, hand chisels, and sandpaper.

1) Squeeze-exhaust suction cups expel all air from the cup by downward squeezing force, creating a negative pressure state inside to hold the workpiece. Advantages include simple structure, light weight, and low cost. However, the suction force is not large, so they are mostly used for workpieces that are not too large in size, thin, and light. 2) Airflow negative pressure suction cups use an airflow control valve to inject compressed air from an air pump through a nozzle, forming a high-speed jet that removes air from the suction cup cavity, creating negative pressure to hold the object. If compressed air is available at the worksite, using this type of suction cup is convenient and low-cost. 3) Vacuum pump exhaust suction cups use an electromagnetic control valve to connect the vacuum pump to the suction cup. When the control valve evacuates air, the air in the suction cup cavity is removed, creating negative pressure to hold the object. Conversely, when the control valve connects the suction cup to the atmosphere, the suction cup loses suction and releases the workpiece. The suction force of vacuum pump suction cups mainly depends on the size of the suction area and the vacuum level inside the cup (referring to the thinness of the air in the q cavity). This type of suction cup is reliable and provides strong suction, but requires a vacuum pump and airflow control system, resulting in higher costs. 4) Mechanical clamping: Structure of a straight-bar dual-cylinder translational gripper. The gripper fingers are mounted on a straight bar equipped with finger mounting seats. When pressurized gas enters the rod-side chambers of the single-acting dual cylinders, the two pistons move toward the center, clamping the workpiece; when no pressurized gas enters, springs push the two pistons outward, releasing the workpiece. To ensure synchronous movement of the two pistons, a flow divider valve is installed in the cylinder intake line. This type of end effector is used in loading and unloading assembly stations.

Explosion-proof tools are internationally known as "safety tools" and "non-sparking tools," and domestically as "explosion-proof tools." In China, explosion-proof tools produced, sold, and distributed are divided into two main categories by material: 1. Aluminum-copper alloy (commonly known as aluminum bronze) explosion-proof tools, specifically made of high-purity electrolytic copper as the base with added aluminum, nickel, manganese, iron, and other metals to form a copper-based alloy. 2. Beryllium-copper alloy (commonly known as beryllium bronze) explosion-proof tools, specifically made of high-purity electrolytic copper as the base with added beryllium, nickel, and other metals to form a copper-based alloy. Both materials have excellent thermal and electrical conductivity. After heat treatment, the hardness and wear resistance of aluminum bronze are nearly identical to those of beryllium bronze, both reaching above HRC30o. Beryllium bronze is non-magnetic and can be used in strong magnetic field environments. Explosion-proof tools can also be divided into two main categories by manufacturing process: 1. Casting process: A traditional manufacturing process that was the international standard for explosion-proof tool production in the 80s and is still widely used by most domestic manufacturers. Advantages of casting: simple process, low manufacturing cost. Disadvantages: lower product density, hardness, tensile strength, and torque; more pores and sand holes, leading to shorter product service life. 2. Forging process: The latest international manufacturing process, using large presses or punch presses with high-heat-resistant forming molds to forge in a single step. Advantages of forging: significantly increases product density, hardness, tensile strength, and torque; basically eliminates pores and sand holes, extending the mechanical performance and service life of the product by approximately 1 times compared to traditional casting. Disadvantages: high investment in equipment and molds, resulting in higher costs.

Hydraulic tools include: hydraulic wrenches, dedicated electric pumps for hydraulic wrenches, hydraulic jacks, hydraulic bolt tensioners, hydraulic flange spreaders, hydraulic nut splitters, hydraulic pullers, etc. Hydraulic tools offer the advantages of high efficiency and convenience. 1) Generally use mineral oil as the working medium; relative moving surfaces are self-lubricating, resulting in long service life. 2) Light weight, compact size, low motion inertia, and fast response speed. 3) Various hydraulic transmission components can be arranged conveniently and flexibly as needed. 4) Automatic overload protection can be achieved. 5) Convenient operation and control, enabling wide-range stepless speed regulation (speed regulation range up to 2000:1). 6) Linear motion is easily achieved. 7) Machine automation is easily achieved; when electro-hydraulic combined control is adopted, not only a higher degree of automatic control can be realized, but remote control is also possible.
