German JUNKER tools JUNKER models JUNKER prices

JUNKER tools utilize electromagnetic technologies such as permanent magnets to assist in mechanical manufacturing processes. They can be categorized into magnetic fixtures, magnetic tools, magnetic molds, and magnetic auxiliary devices. The use of magnetic tools can significantly improve production efficiency and reduce the physical workload of employees. For some workpieces, clamping is inconvenient during machining and assembly due to their structural characteristics. By vertically positioning the U-shaped iron core on the worktable for processing, one only needs to embed a magnet in the locating block of the fixture to firmly hold the workpiece by magnetic attraction on the worktable equipped with the locating block, while ensuring accurate positioning. This greatly simplifies the fixture structure and improves work efficiency. Some products require welding small parts onto the workpiece; if accurate positioning is not achieved, it not only makes the work difficult but also fails to meet requirements.

JUNKER tool applications and usage

The electric hydraulic oil pump can serve as the hydraulic pump for various hydraulic devices. When paired with other hydraulic tools, the electric hydraulic oil pump can perform tasks such as lifting, pressing, pipe bending, bar bending, straightening, shearing, assembly, and disassembly. It reduces labor intensity and improves work efficiency. During use, open the air release nut, turn on the switch on the oil collection block, connect the power supply, and attach the quick connector to the quick coupling on the corresponding hydraulic device. Press the power switch and let the motor run for 1-2 minutes. Then turn off the switch to set it to the pressure-boosting state. At this time, the output hydraulic oil will perform various tasks, with the pressure automatically increasing as the load increases until it reaches 63MPA. After work is completed, open the switch to relieve the load. Once the hydraulic oil has returned, remove the quick connector, tighten the air release nut, unplug the power cord, and close the switch.

JUNKER tool structure and composition

The function of the power component is to convert the mechanical energy of the prime mover into the pressure energy of the fluid. 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 fluid 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 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 into on-off control valves, fixed-value control valves, and proportional control valves. Auxiliary components include oil tanks, oil filters, oil pipes and pipe fittings, sealing rings, pressure gauges, oil level and temperature gauges, etc. Hydraulic oil is the working medium that transmits energy in the hydraulic system, including various mineral oils, emulsions, and synthetic hydraulic oils.

JUNKER tool usage

1) Before use, carefully inspect the tool to ensure there is no external damage, the switch operates flexibly without sticking, and the power cord and housing of the electric tool are intact. Use a 500V megohmmeter to measure the insulation resistance between the winding and the housing; the value must not be lower than O.5 megohms. See the attached table for insulation resistance values. 2) Handheld electric tools with metal housings must have a reliable protective grounding wire. The power cord should be a multi-core soft rubber-sheathed cable, and the grounding protection wire at both ends must be securely connected. 3) Handheld electric tools should be used by dedicated personnel with certain professional knowledge. Strictly adhere to relevant safety operating procedures during use. 4) Before use, first check whether the relevant electrical and mechanical protection devices are intact and functioning normally. Also, ensure that the rotating parts move flexibly without sticking. 5) When using Class I handheld electric tools, users must wear prescribed protective equipment and use qualified protective gear. Take appropriate anti-electric shock safety measures as required, such as installing a residual current device (RCD) in the power circuit, or having the user wear insulating gloves, insulating shoes, or stand on an insulating mat. When using Class II handheld electric tools in damp and narrow spaces, install a leakage switch with a working current of less than 1.5mA and an action time of less than or equal to 0.1 seconds. The leakage switch should be placed inside the container and monitored by a dedicated person. 6) Occupational hazards of using handheld electric tools. Arm vibration disease caused by long-term hand-transmitted vibration work was listed as one of China's statutory occupational diseases as early as 1957, also known as local vibration disease, typically manifested by paroxysmal white finger.
