Description
Technical field
The present invention relates to a kind of electromagnetic hammer, particularly a kind of magnetic hammer that is used for processing of ferromagnetism sheet metal component and maintenance correction belongs to the hardware ﹠ tools technical field.
Background technology
At present, the school is processed and repaiied to the method that generally adopts hammering or pull sled to the ferromagnetism sheet metal component.As a rule, owing to be subjected to the workpiece structural limitations, very difficulty is operated in the school of repairing of sheet metal component usually, and high to the requirement of operator's level of skill, often need to increase many back works during not only inefficiency, and operation and realize.The quality of panel beating depends on operator's practical skill level, and present method can not satisfy the requirement of real work well.
The covering of vehicle is mainly sheet metal component, and along with popularizing of Modern Car, because the requirement of internal structure and external styling is also more and more high to the requirement of sheet metal component, the panel beating to production and processing and later period maintenance timing requires also more and more higher like this.The damage of vehicle housing coverings such as (casings) is depression more than 80%, when it is carried out sheet metal work, generally all will remove the associated components that influences the panel beating operation earlier, has not only increased a large amount of back work amounts, and has caused these damage of components easily.For adopting outside weldings to draw the calibration method of repairing in school at recess, often need that the several welding is carried out at the depression position and repair the school, also want butt welding point to handle then; The process equipment that adopts this method of drawing the school not only to relate to is many, and needs a plurality of work posts to finish jointly.So both increase machining period, increased cost greatly, destroyed the stress distribution of original metalwork structure simultaneously again.
Summary of the invention
The purpose of this invention is to provide a kind of electromagnetic hammer, depend on operator's practical skill level in order to the quality that solves present production and repair the school sheet metal component, particularly when repairing school panel beating depression damage, relate to process equipment and work post is many, machining period is long, the problem that cost is high.
For achieving the above object, the present invention adopts following technical scheme: a kind of electromagnetic hammer, comprise magnetic head, and this magnetic head front end is that working end, rear end are the force side, the dismantled and assembled electromagnetism hammer handle that is fixed with in the force side of described magnetic head; Described electromagnetism hammer handle comprises shell body, be installed with the solenoid that axis extends along the magnetic head fore-and-aft direction in this shell body, slip is fitted with an end and is exposed to the outer armature of solenoid in the centre bore of this solenoid, and this armature is exposed between outer end of solenoid and solenoid and is pressed with spring; Be provided with the striking face that clashes into for armature corresponding to the armature position place on the described shell.
The branch magnetic head of two soft magnetic materials that are fixed together side by side about described magnetic head comprises, corresponding clip is equipped with non-magnetic conduction thin plate between two fens magnetic head opposite faces, the side of this magnetic head is provided with circular hole, the axis of described circular hole is positioned at the vertical plane at non-magnetic conduction thin plate place, be rotatably equipped with magnet in the described circular hole, described magnet two magnetic pole lines are vertical with the center line of circular hole.
Described shell body is provided with the by-pass cock of this electromagnetic hammer power output size of control, and this by-pass cock is connected with the solenoid conduction.
Described striking face is provided with cushion pad.
Electromagnetic hammer according to claim 3 is characterized in that: described non-magnetic conduction thin plate is aluminium sheet or copper coin etc.
Electromagnetic hammer of the present invention has a magnetic head, magnetic head is adsorbed on the sheet metal component for the treatment of shaping during work, power to solenoid then, make the striking face on the armature bump shell, operate corresponding to " pressure " hammering when striking face is positioned near head position, when striking face is positioned at away from head position, operate corresponding to " drawing " hammering.As seen, after adopting this electromagnetic hammer, reach " drawing " when operation sheet metal component being carried out " pressure ", side at sheet metal component gets final product complete operation, do not need sheet metal component is dismantled, and no longer need other auxiliary equipment, only a work post gets final product complete operation, saved man-hour greatly, reduced cost.
As another improvement of the present invention, described magnetic head comprises that two symmetrically arranged soft magnetic materials divide magnetic head, be provided with magnet between two fens magnetic heads, magnet can rotate in the circular hole in magnetic head, define here the trend of magnetic pole when consistent with the magnetic head fore-and-aft direction angle of magnet be 0 °, this moment, the magnetic line of force of magnet was in short-circuit condition, again because magnetic head is soft magnetic materials (as a cast iron), when the magnetic line of force short circuit of magnet, magnetic head loses magnetism, and discharges the state of sheet metal component corresponding to magnetic head.Magnet is carried out 0 ° to 90 ° when rotation, and the magnetic field intensity of magnetic head induction is by 0 to the strongest, and this moment is corresponding to the state of magnetic head absorption sheet metal component.This electromagnetic hammer at first was adsorbed onto it on sheet metal component in when work, and according to the angle that the size of the power of need of work is come regulating magnet, obtained different absorption affinities.Regulate the by-pass cock of control power output size then according to required percussion power.The electromagnetism hammer handle is dismantled and assembled being fixed on the magnetic head, and when armature was near the head position place, this electromagnetic hammer was realized " drawing " hammering operation; When the electromagnetism hammer handle being turned over direction installs is armature during away from magnetic head, and this moment, this electromagnetic hammer realized that " pressures " hammering operates.
