German KTS tools KTS models KTS prices

KTS tools integrate hydraulic systems with conventional tools into a unified whole. They convert powerful hydraulic power into mechanical motions such as reciprocating linear motion, rotary motion, and cycloidal motion. A complete hydraulic tool system consists of five components: power elements, actuating elements, control elements, auxiliary elements, and hydraulic oil. Hydraulic tools include: hydraulic wrenches, electric pumps dedicated to 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.

KTS tool classification

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. They feature 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 force and releases the workpiece. The suction force of vacuum pump suction cups mainly depends on the size of the suction area and the degree of vacuum in the inner wall (referring to the thinness of the air in the inner q cavity). This type of suction cup is reliable and provides greater suction force, but requires a vacuum pump and airflow control system, resulting in higher costs. 4) Mechanical clamping type: The structure of a straight-bar dual-cylinder translational gripper involves gripper fingers 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 synchronized 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 workstations.

KTS tool structural composition

The function of power elements is to convert the mechanical energy of the prime mover into fluid pressure energy. 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. Actuating elements (such as hydraulic cylinders and hydraulic motors) convert fluid pressure energy into mechanical energy, driving loads to perform linear reciprocating motion or rotary motion. Control elements (i.e., various hydraulic valves) control and regulate the pressure, flow rate, and direction of the fluid in the hydraulic system. Depending on the control function, 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. Depending on the control method, hydraulic valves can be divided on/off control valves, fixed-value control valves, and proportional control valves. Auxiliary elements include oil tanks, oil filters, oil pipes and pipe fittings, sealing rings, pressure gauges, oil level and oil temperature gauges, etc. Hydraulic oil is the working medium that transmits energy in hydraulic systems, including various mineral oils, emulsions, and synthetic hydraulic oils.

KTS tool types and features

Hydraulic tools include: hydraulic wrenches, electric pumps dedicated to 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 can self-lubricate, resulting in long service life. 2) Light weight, small volume, low motion inertia, and fast response speed. 3) Various hydraulic transmission components can be conveniently and flexibly arranged as needed. 4) Automatic overload protection can be achieved. 5) Convenient operation and control, capable of achieving 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 process can be realized, but also remote control can be achieved.
