German MOLITAL tools MOLITAL models MOLITAL prices

MOLITAL tools are made of copper alloy. Due to the good thermal conductivity of copper and its characteristic of being almost carbon-free, the heat generated in a short time when the tool rubs against or impacts an object is absorbed and conducted. Another reason is that copper itself is relatively soft, providing good compliance during friction and impact, making it difficult to produce tiny metal particles, so we hardly see any sparks. Therefore, explosion-proof tools are also called non-sparking tools. The materials for explosion-proof tools are beryllium bronze and aluminum bronze. Beryllium bronze alloys and aluminum bronze alloys do not spark upon impact or friction, making them very suitable for manufacturing safety tools used in explosive, flammable, strong magnetic, and corrosive environments. BeA-20C alloy withstands an impact energy of 561IJ in hydrogen containing 30% or in methane-air-oxygen mixtures containing 6.5-10%, undergoing 20 impacts without sparking or ignition.

MOLITAL tool description

Various lifting tools have different uses and significant structural differences, but all possess a hoisting mechanism to achieve the basic action of lifting and lowering. Materials can be lifted and lowered by hanging from flexible components such as wire ropes or lifting chains, or they can be jacked up by screws or other rigid components. Lifting tools can be classified into light and small lifting equipment, hoists, and overhead monorail systems based on their structure. Light and small lifting equipment mainly includes lifting pulleys, slings, jacks, triangular hand chain hoists, electric hoists, and ordinary winches. Most are small in size, light in weight, and simple and convenient to use. Except for electric hoists, the vast majority are human-powered, suitable for occasions where the workload is not heavy. They can be used individually, and some can also be used in combination. Some light and small lifting equipment has a large lifting capacity; for example, the lifting capacity of hydraulic jacks has reached 750 tons. Mine hoists and bucket elevators mainly perform vertical or near-vertical lifting movements with fixed lifting routes. Overhead monorail systems have lines formed by rigid suspension tracks, which can transport materials to various parts of the factory building and can also extend to the exterior of the factory building.

MOLITAL tool structure composition

The function of power components is to convert the mechanical energy of the prime mover into the pressure energy of the liquid. This refers to the oil pump in the hydraulic system, which provides power to the entire hydraulic system. The structural forms of hydraulic pumps generally include gear pumps, vane pumps, and piston pumps. The function of actuating components (such as hydraulic cylinders and hydraulic motors) is to convert the pressure energy of the liquid into mechanical energy, driving the load to perform linear reciprocating motion or rotary motion. Control components (i.e., various hydraulic valves) control and regulate the pressure, flow, and direction of the liquid in the hydraulic system. According to different control functions, hydraulic valves can be divided into pressure control valves, flow control valves, and directional control valves. Pressure control valves are further divided into relief valves (safety valves), reducing valves, sequence valves, pressure relays, etc.; flow control valves include throttle valves, adjustment valves, flow divider-combiner valves, etc.; directional control valves include check valves, pilot-operated check valves, shuttle valves, directional valves, etc. According to different control methods, hydraulic valves can be divided into on-off control valves, fixed-value control valves, and proportional control valves. Auxiliary components include oil tanks, oil filters, oil pipes and pipe joints, sealing rings, pressure gauges, oil level and oil temperature gauges, etc. Hydraulic oil is the working medium for transmitting energy in hydraulic systems, including various mineral oils, emulsions, and synthetic hydraulic oils.

MOLITAL tool usage

1) When placing the diamond dressing tool head into the holder, be careful not to impact the grinding wheel surface. 2) Do not align the single-point diamond dressing tool head vertically with the center of the grinding wheel; it generally needs to be tilted by 10-15°. 3) Do not "quench" (i.e., suddenly cool) a heated dressing tool. During dry dressing, the interval between two dressings must be sufficient to allow the heated dressing tool to cool down. 4) Do not assume that the grinding wheel surface is ideally flat. At the beginning of dressing, locate the high points on the grinding wheel and perform dressing. 5) If possible, the amount removed from the grinding wheel each time should not exceed 0.001 inches on the radius of the grinding wheel. Excessive removal can cause premature wear and frequent breakage of the diamond dressing tool head. 6) However, do not remove too little material each time. Grinding wheels used on old or poorly rigid machine tools may not require dressing. 7) Note that the dressing tool should not stay in one position for too long. This will polish the grinding wheel surface, generate high temperatures, and damage the diamond dressing tool. Rotate the dressing tool at least once a day. 8) Do not continue to use worn or damaged dressing tools. Adjust or replace them in time. 9) Do not select excessive removal amounts and too fast lateral feed rates during rough dressing, and then select small removal amounts and slow lateral feed rates during fine dressing. This will quickly damage the diamond dressing tool. If possible, it is recommended to select the same lateral feed rate for both rough and fine dressing.
