Abstract
The utility model relates to a pulse DC tractive magnet which is a device for the traction of advance and retreat clutching of a large-sized machinery device component. The utility model has the technical scheme that a coil is arranged at the inner wall of a casing, and the inner wall of the coil is provided with a guide sleeve. The bottom of the casing is provided with a block iron, the upper part of the center of which is provided with a magnetic steel. The top of the casing is provided with a limited cap, and the inner cavity of the casing is provided with an armature, the upper end of which is connected with a connecting rod which penetrates through the centre hole of the limited cap. The exterior surface of the upper section of the armature is sheathed with a magnetic isolating pipe. Compared with the original tractive magnet, the weight of the utility model is reduced by 2/3-3/4, and a raw material is saved. The power supply is changed from the original full work time supply to instant DC pulse supply, and the power is saved by more than 90 percent. The utility model has the advantages of small impact force, small temperature rise, long service life, simplified fabrication technology and low cost when the utility model works. The application foreground of the pulse DC tractive magnet is very wide.
Description
One, technical field
The utility model is the device that is used to draw the clutch of heavy mechanical equipment parts advance and retreat.
Two, background technology
Certain the parts advance and retreat clutch that is used for big machineries such as large-scale punch press, forcing press, plate shearing machine and boats and ships is controlled by control system, and tractive electromagnet is the important device in the control system.Present tractive electromagnet is that silicon steel sheet is that the iron core coiling is made mostly, and by Alternating Current Power Supply, coil is fragile, and its volume is big and heavy, and noise and impulsive force are bigger, and useful life is short.It is uninterrupted to power when working because of it, and power consumption is big, and it is unfavorable that precision apparatus is used.
Three, summary of the invention
The utility model is in order to provide a kind of volume little, little power consumption, and noise is little, the tractive electromagnet of working stability and long service life.
This Design of device scheme is: be equipped with coil in inner walls, the coil inwall is equipped with fairlead, housing bottom is equipped with buting iron, the buting iron central upper is equipped with magnet steel, case top is equipped with limited cap, the housing inner chamber is equipped with armature, and the armature upper end is connected with the connecting rod that passes the limited cap centre bore, and armature epimere outer surface is with plunger tube.The internal diameter of fairlead and limited cap is consistent, and the internal diameter of the device inner chamber of being made up of them is more bigger than armature external diameter.The length of armature is 1/2～3/4 of the interior cavity length of device.Top of chamber is equipped with cushion pad in the limited cap.Buting iron and magnet steel are connected as a single entity with utmost point magnet.
This device is compared with former tractive electromagnet, and raw material have been saved in weight saving 2/3～3/4, and power supply has changed moment DC pulse power supply into by original power supply full time, and economize on electricity is more than 90%.Impulsive force is little and steady during its work, and temperature rise is little, and prolong useful life.Its processing technology is simplified, and cost reduces.This device application prospect is boundless.
Four, description of drawings
Accompanying drawing is a general assembly structural representation cutaway view.
Five, embodiment
This device can be made as series of products according to the purposes difference, and metal hollow housing 1 inwall is equipped with coil 2, and the wire-wound of coil 2 is on skeleton 3, and coil 2 is stuck in the interior location of last yoke cover in the housing 1.Be close to skeleton 3 inwalls and be equipped with a guiding magnetic shield 4 of making by stainless steel material.Embed magnetic conductor buting iron 5 from housing 1 infraoral, buting iron 5 center upper surface are equipped with magnet steel 6, with utmost point magnet 7 magnet steel 6 and buting iron 5 rivetings are integral together.The upper oral part of housing 1 is fixed with limited cap 8 with trip bolt 12.Armature 9 is circular magnetic conductor, and its top one is connected with pull bar 10, and it passes limited cap 8 centre bores and stretches out and connect required control device, and armature 9 upper end outer surfaces are with one section stainless steel plunger tube 13, to eliminate remanent magnetism.Guiding magnetic shield 4 is consistent with the internal diameter of limited cap 8, and is more bigger than armature 9 external diameters.Impact when armature 9 rises for alleviating, be equipped with cushion pad 11 in limited cap inner chamber upper end.The length of armature 9 is that utmost point magnet 7 upper surfaces are to 1/2～3/4 of cushion pad 11 lower surfaces.Coil 2 is an example to replace old product MQ1-25, and Φ 0.41 gets final product around 2400 circles with the line footpath.During use, the low-voltage DC end that is provided by controller is provided at the coil-winding two ends, pull bar connects the device of being controlled and gets final product.When controller for coil provide positive direction be about 0.2 second instantaneous DC pulse the time, armature is firmly held by magnet steel, make pull bar pulling control device, at this moment, this device is in off-position, pickup time is long arbitrarily.When the needs releasing lever, provide about 0.05 second reverse DC pulse of moment to coil, armature will leave magnet steel, and simultaneously pull bar upwards by the counter-force original place of rebounding, is finished reciprocating motion once.This electromagnet also can be used as driving and uses.
