Description

A kind of sawtooth sticky bits pulsed magnetic field removal device

Technical field

The present invention relates to bands for band sawtooth sticky bits device, particularly relate to a kind of sawtooth sticky bits pulsed magnetic field removal device.

Background technology

Visual plant during band saw machine manufactures as machining, its machining accuracy is directly connected to efficiency and the quality of subsequent handling, but due to the technical limitation of existing processing method, make when band sawing machine works, always there is part scrap to be attached on band saw, thus stock-removing efficiency can be declined greatly, and accelerate band saw for metal wearing and tearing, increase the sawing load of motor, also can increase the roughness of workpiece machining surface simultaneously.

Owing to removing Integrated Chip, sawing process is had great significance, therefore investigated now many kinds and removed the Integrated Chip removal device being attached to Integrated Chip on sawtooth.The patent being CN 1925942A as publication number is exactly a kind of smear removal device.This device is equipped with a pair in the two sides of sawtooth can to the close brush support body with deviating from the swing of band sawtooth direction, brush is configured to relative to band sawtooth moving direction inclined downward forward, augmentor is equipped with brush support body also, by brush from being with sawtooth tooth root side to the rotation of crown side to remove chip simultaneously.In this class Integrated Chip removal device, its general principle is all utilize the swing of brush to remove the Integrated Chip on sawtooth.The shortcoming of this kind of device is that the structure of device is too complicated, not only comprises brush support body, also needs the device of augmentor and driven brush swing or rotation; In addition, due to the vibrations of saw blade in the irregular of zigzag fashion and working angles, make brush can not with sawtooth good contact, easily cause the residual of Integrated Chip.

Summary of the invention

The present invention is directed to the technical barrier of the not easy-clear of Integrated Chip in existing band saw, a kind of sawtooth sticky bits pulsed magnetic field removal device is provided.

A kind of sawtooth sticky bits pulsed magnetic field removal device, comprises pulse alternating source, clamping device, the first solenoid, the second solenoid, industrial computer and iron core; Iron core comprises the first iron core and the second iron core, the first described iron core is identical with the second core structure, the first described iron core and the second iron core are rectangular configuration, its bottom has an opening, first iron core is wound around the first solenoid, second iron core is wound around the second solenoid, and the winding direction of the first solenoid and the second solenoid is contrary;

The first described iron core and the second iron core are fixed on the crossbeam of sawing machine respectively by a clamping device, an end face of the first iron core and the second iron core aims at a side of bands for band respectively, and another end face of the first iron core and the second iron core aims at another side of bands for band respectively; Described first solenoid, the second solenoid are connected with pulse alternating source respectively, and pulse alternating source is connected with industrial computer by external cable.

Beneficial effect of the present invention: the present invention utilizes alternating current to produce strong pulsed magnetic field in the solenoid of silicon steel core, in order to the Integrated Chip on magnetization saw sword, make Integrated Chip bear alternating magnetic field power, thus realize sawtooth and peel off mutually with Integrated Chip, the Integrated Chip be stripped is adsorbed onto on iron core thereupon.In working angles, by data collecting card and industrial computer, monitoring is realized to alternating current and pulsed magnetic field; After workpiece cutting terminates, stop solenoid, Integrated Chip is no longer subject to electromagnetic force, can realize the automatic discharge of Integrated Chip, to reduce hand labor.Thus this patent can reach the effect reducing bands for band wearing and tearing, reduce motor sawing load and workpiece machining surface roughness, to improve stock-removing efficiency.

Detailed description of the invention

Below in conjunction with accompanying drawing, this patent is further described.

As shown in Figures 1 and 2, a kind of sawtooth sticky bits pulsed magnetic field removal device, comprises pulse alternating source 2, clamping device 3, first solenoid 4, second solenoid 5, industrial computer 6 and iron core 7; Iron core 7 comprises the first iron core and the second iron core, the first described iron core is identical with the second core structure, the first described iron core and the second iron core are rectangular configuration, its bottom has an opening, first iron core is wound around the first solenoid 4, the winding direction that second iron core is wound around the second solenoid 5, first solenoid 4 and the second solenoid 5 is contrary;

The first described iron core and the second iron core are fixed on the crossbeam 1 of sawing machine respectively by a clamping device 3, an end face of the first iron core and the second iron core aims at a side of bands for band 8 respectively, and another end face of the first iron core and the second iron core aims at another side of bands for band 8 respectively; Described first solenoid 4, second solenoid 5 is connected with pulse alternating source 2 respectively, and pulse alternating source 2 is connected with industrial computer 6 by external cable.

The removal process that sawtooth glues bits is as follows: when bands for band cutting workpiece, passes into pulse alternating current by industrial computer 6 control impuls alternating source 2 to the first solenoid 4 and the second solenoid 5; Will produce a strong pulsed magnetic field perpendicular to bands for band 8 direction of motion between two end faces of the first iron core, between two end faces of the second iron core, also can produce a strong pulsed magnetic field, but the magnetic direction between direction with the first iron core end face is contrary; When the bands for band with sticky bits moves between the both ends of the surface of the first iron core, the sticky bits on it will be magnetized by the strong pulsed magnetic field between the first iron core end face, and sticky bits will be subject to the strong attraction of pulsed magnetic field; Because the pulse current passing into coil 4 and 5 is high-frequency alternating change, the strong pulsed magnetic field therefore between the first iron core and the sticky strong attraction be subject to of considering to be worth doing are also all high-frequency alternating changes; With stressed situation of change between second iron core end face of the bands for band 8 of sticky bits and similar between first iron core end face, but sticky bits stressed be the high frequency forced-ventilated repulsion of pulsed magnetic field; Sticky bits repel through Electro Sorb and electricity repeatedly between two iron core end faces, magnetic suck and magnetic repulsion, will be separated, thus realize the removal of sticky bits on bands for band 8 with bands for band 8; According to the anti-dandruff situation of on-the-spot bands for band 8, can be controlled by industrial computer 6 paired pulses size of current, and then realize the control of pulse magnetic field intensity and anti-dandruff situation in working angles; After working angles terminates, as long as disconnect the electric current passed in solenoid 4 and 5, the stripping of chip and solenoid can be realized, namely achieve the automatic discharge of Integrated Chip, to reduce hand labor and to save time.
