German TESA TECHNOLOGY tools, TESA TECHNOLOGY models, TESA TECHNOLOGY prices

TESA TECHNOLOGY tools, also known as hand tools, are distinguished from power tools. They primarily rely on manual force to turn or apply pressure. Hand tools are categorized by use into wrenches, pliers, screwdrivers, tape measures, hammers, sockets, cutting tools, scissors, tool sets, and accessories such as tool carts, with each category having different models. Wrenches include open-end wrenches (fixed wrenches), double box-end wrenches, ratchet wrenches (quick wrenches), combination wrenches, pipe wrenches, T drive socket wrenches, cross socket wrenches, and adjustable wrenches; pliers include wire cutters, needle-nose pliers, diagonal cutters, snap-ring pliers, slip-joint pliers, water pump pliers, pipe wrenches, and locking pliers; screwdrivers include slotted, Phillips, Pozidriv, hex, and Torx types; sockets are divided into standard sockets, Torx sockets (E sockets), bit sockets (BIT sockets), spark plug sockets, and impact sockets. Common drive sizes are 1/4", 3/8", and 1/2", where " denotes inches; each size is available in 6-point and 12-point sockets; hammers include claw hammers, machinist hammers, ball-peen hammers, rubber mallets, and installation hammers; cutting tools include files, diamond files, tin snips, aviation snips, utility knives, square tube saws, pipe cutters, and bolt cutters; materials include chrome vanadium steel, carbon steel, and alloy steel.

TESA TECHNOLOGY tool classification

1) Squeeze-exhaust suction cups expel all air from the cup by downward squeezing force, creating a vacuum to hold the workpiece. Advantages include simple structure, light weight, and low cost. However, the holding force is not large, making them suitable for small, thin, and light workpieces. 2) Air-flow vacuum suction cups use an airflow control valve to inject compressed air from a pump through a nozzle, creating a high-speed jet that removes air from the suction cup cavity, forming a vacuum to hold the object. This type is convenient and low-cost if compressed air is available on site. 3) Vacuum pump exhaust suction cups connect a vacuum pump to the suction cup via an electromagnetic control valve. When the valve evacuates air, a vacuum is formed in the cup to hold the object. Conversely, when the valve connects the cup to the atmosphere, the vacuum is lost and the workpiece is released. The holding force depends mainly on the suction area and the degree of vacuum in the inner q cavity (indicating the rarefaction of air). This type is reliable with high holding force but requires a vacuum pump and airflow control system, resulting in higher costs. 4) Mechanical clamping: The structure of a straight-bar dual-cylinder translational gripper involves fingers mounted on a straight bar with finger mounts. When pressurized gas enters the rod-side chambers of the single-acting dual cylinders, the two pistons move inward to clamp the workpiece; when no pressure is applied, springs push the pistons outward to release the workpiece. A flow divider valve is installed in the intake line to ensure synchronized piston movement. This end effector is used in loading and unloading assembly stations.

TESA TECHNOLOGY tool selection guide

Precautions for selecting power tools: First, a power tool is a handheld or portable mechanized tool powered by an electric motor or electromagnet, driving a working head via a transmission mechanism. Power tools are characterized by portability, ease of operation, and multifunctionality, significantly reducing labor intensity and improving efficiency by mechanizing manual operations. They are widely used in construction, home decoration, automotive, machinery, electrical power, bridge building, gardening, and other fields, and have entered households in large numbers. Features include lightweight compact structure, low vibration, low noise, flexible operation, easy control, portability, durability, and robustness. Compared to hand tools, they can increase labor productivity by several to dozens of times; compared to pneumatic tools, they offer higher efficiency, lower cost, and easier control.

TESA TECHNOLOGY tool types and features

Hydraulic tools include: hydraulic wrenches, dedicated electric pumps for hydraulic wrenches, hydraulic jacks, hydraulic bolt tensioners, hydraulic flange spreaders, hydraulic nut splitters, and hydraulic pullers. Hydraulic tools offer high efficiency and convenience. 1) Mineral oil is generally used as the working medium, providing self-lubrication for moving surfaces and 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 is achievable. 5) Easy 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 realized; with electro-hydraulic combined control, not only a higher degree of automatic control but also remote control can be achieved.
