General operating procedures Forging screw machine

1, the operator must pass an examination, held by the device's "device operating certificate" before operating the screw machine.

2, before the serious work to do:

(1) read the shift record, to understand the class work.

(2) Check whether the screw machine and workplace clean, wipe clean; screw machine, bed, work table, rails and other obstructions shall not be the main sliding surface, impurities, and a new pull, research, and bruising. If the above must be removed, and wipe clean and screw machine; the emergence of new pull, research, and bruising members or group leaders should be invited to screw machine with view, and make records.

(3) Check the operating mechanism of the handle, valves, rods, and all the major parts and components (slide, hammer, knife, etc.) should be placed on non-manual work required position.

(4) Check all safety devices (protective cover, limit switches, limit file iron, electrical grounding, safety device, etc.) should be complete in good condition, installed correctly and reliable; distribution box (box), the fuel tank (pool), transmission The door cover should be closed.

(5) Check the lubricating parts (oil tank, oil tank, oil cups, and other sliding surface rail) fuel should be sufficient, according to the chart oil lubrication instructions.

(6) Check all the major parts and components as well as any abnormal loosening fasteners.

(7) to open the gas (steam) way valves, check valves and other devices pipeline leak should be in good condition, gas (steam), the pressure shall comply with requirements, and let go of control of the water.

(8) empty running test, starting to jog, check the operation device, safety device (brake, change direction, interlocks, limit, insurance, etc.) of the indicating device (indicating meters, lights, etc.) should be sensitive, accurate and reliable; action should be coordinated in different parts; oil should be normal, lubrication should be good; machine operation without abnormal noise, vibration, temperature, odor, smoke and so on. Sure everything is normal, before starting work. Where the screw machine with shift work, shift personnel to the above (8) provides a common examination for shift change; where every class to take over the screw machine, found on the phenomenon of a group of serious violations of operating procedures, screw machine, staff or group leaders should be invited to have view, and recorded, or screw machine problems to occur This class of violation of operating rules. After adjustment or repair screw machine, the operator must be in accordance with the above (8) and the steps required to inspect the screw machine, making sure everything is correct before starting work.

3, serious work to do:

(1) commitment to work, careful operation of screw machine, do not do things not related to work. Because the incident left the device to shut down and turn off the electricity, gas (steam) source.

(2) the technical specifications provided by manual use of screw machine, shall not exceed the norms, overload devices.

(3) pay close attention to all parts of lubrication screw machine, lubrication instructions according to the provisions of classes filling the chart to ensure good lubrication of all parts of screw machine.

(4) pay close attention to the work of various parts of screw machine, if any abnormal sound, vibration, temperature, odor, smoke, incoordination, failure and so on, should immediately stop to check, remove and then continue working.

(5) The governor, the replacement of the mold, tool, or smear, maintenance screw machine, prior to shutdown, turn off electricity, gas (steam) source.

(6) at work, not allowed to remove safety guards and open the distribution box (box), pool (me), transmission of the door cover to work.

(7) screw machine must be immediately shut down the incident, protect the scene, the report analysis and processing departments.

4, after the serious work to do:

(1) The operating device and the slider, hammer, knife and other requirements shall be specified on the non-working position; off electricity, gas (steam) source.

(2) finishing tools, parts and work sites.

(3) work space and screw machine cleaning materials on the head, material side, scale, debris, etc.; wipe the screw machine clean and all parts, the sliding surface oil protection.

(4) recorded a complete shift change.
