German BLACK & DECKER tools BLACK & DECKER models BLACK & DECKER prices

BLACK & DECKER tools are any tools connected to the robot edge (joint) with specific functions. This may include robot grippers, robot tool changers, robot collision sensors, robot rotary connectors, robot pressure tools, compliance devices, robot spray guns, robot deburring tools, robot arc welding torches, robot electric welding torches, etc. Robot end effectors are generally considered robot peripherals, robot accessories, robot tools, and arm-end tools (EOA). Mechanical gripping end effectors used in loading and unloading industrial robots are mostly two-finger claw types. Classified by finger motion, they can be divided into translational and rotational types. Classified by mechanical clamping method, they can be divided into external clamping and internal expanding types. Classified by mechanical structural characteristics, they can be divided into electric (electromagnetic), hydraulic, and pneumatic types, as well as their combinations.

BLACK & DECKER tool principles

The principle of hydraulics consists of two cylinders of different sizes filled with water or oil. Water-filled ones are called "water presses"; oil-filled ones are called "oil presses." Each cylinder contains a sliding piston. If a certain pressure is applied to the small piston, according to Pascal's law, the small piston transmits this pressure through the fluid pressure to the large piston, pushing it up. Let the cross-sectional area of the small piston be S1, and the downward force applied to the small piston be F1. Thus, the pressure exerted by the small piston on the fluid is P=F1/SI, which can be transmitted unchanged in all directions by the fluid." The pressure received by the large piston must also equal P. If the cross-sectional area of the large piston is S2, the upward force F2=PxS2 generated by the pressure P on the large piston is a multiple of the small piston's cross-sectional area. From the above equation, applying a smaller force to the small piston results in a larger force on the large piston. Therefore, hydraulic presses are used for pressing plywood, extracting oil, lifting heavy objects, forging steel, etc.

BLACK & DECKER tool usage

1) Select the appropriate saw blade for the workpiece. For example, use 14 teeth per inch for cutting solid or thick soft metals; use 18 teeth per inch for tool steel, iron pipes, and hard metals; and 24 teeth per inch are suitable for cutting metal sheets, metal pipes, and thin iron bars. 2) Push the saw forward, and lift it gently when pulling back. 3) Select a wrench of appropriate size according to the nature of the work. 4) When using an adjustable wrench, apply force towards the fixed jaw, never towards the movable jaw. 5) If the wrench opening is worn or slips during use, do not continue using it to prevent slipping. 6) Do not use a wrench as a hammer for striking. 5. Do not slip a pipe over the wrench handle to increase torque. 7) Press the inner side of the first leg of the square against the edge of the wooden board, and draw along the inner side of the second leg with a pencil to mark a perpendicular line. 8) Select the appropriate screwdriver according to the size and shape of the screw head slot. 9) Do not strike the screwdriver handle with a hammer; replace damaged handles immediately. 10) Do not use a screwdriver as a chisel or lever. 11) Use an electrician's screwdriver to test current; do not use ordinary screwdrivers to test high voltage. 12) Do not grind the screwdriver tip to avoid damaging the hardened surface. 13) Do not keep screwdrivers in shirt or trouser pockets to prevent injury from collisions or falls.

1) Plane blade adjustment: When installing the plane blade, first fit the blade with the cap iron, control the distance between their cutting edges, and then insert it into the plane body. Bring the cutting edge close to the sole, add the wedge, press down slightly, hold the left corner of the sole with the left hand, and use the thumb to firmly hold the wedge, cap iron, and plane blade. Use a hammer to correct the cutting edge so that it protrudes from the mouth. The amount of protrusion is proportional to the cutting depth: more for rough planing, less for fine planing. To check the blade protrusion, lift the plane with the left hand, sole facing up, and look backwards with one eye to detect it. If the protrusion is inappropriate, tap the upper end of the blade lightly. If it protrudes too much and needs to be retracted, tap the rear end of the plane body lightly. If one corner of the cutting edge protrudes, simply tap the upper side of the same corner of the blade. 2) Planing points: When planing, extend the index fingers of both hands forward to press on the plane body, press the rear of the blade with the thumbs, and grip the handle tightly with the remaining fingers and palms. Keep the plane body level and apply uniform force with both hands. When pushing forward, increase the force with both thumbs and apply slight pressure with the index fingers. Gradually reduce the pressure as you reach the front end until no pressure is applied. When retracting, lift the rear of the plane body slightly with your hand to prevent the cutting edge from dragging on the wood surface, which causes dulling. When planing long stock, place the left foot forward, then follow with the right foot. Before planing long stock, check whether the surface is heartwood or sapwood. Generally, heartwood is cleaner and has clearer grain than sapwood. If it is heartwood, plane from the root to the tip; if it is sapwood, plane from the tip to the root. Planing along the wood grain saves effort. Otherwise, it is easy to cause "tear-out," resulting in a rough, uneven surface and requiring excessive effort. When starting a cut, the plane sole should fit tightly against the wood surface. Do not lift the front of the plane at the start, and do let the front dip at the end (commonly known as "nodding"). Otherwise, the middle part of the planed surface will bulge unevenly, a common mistake among beginners that must be corrected.
