Abstract

The utility model discloses a hand electromagnetic ferric saw, which is added with an electromagnetic attraction-operated mechanism on the base of the hand ferric saw. The automatic cutting of the ferric saw is realized by the electromagnetic vibration is used as the power. Thereby, the hand ferric saw, which implements the cutting by human pushing and pulling, is replaced. Hence, the physical labour of the operator is lightened and the work efficiency is improved. The utility model has the advantages of simple structure and reliable performance.

Description

The utility model relates to a kind of hand to be sawed with iron, and particularly a kind of hand that adopts electric and magnetic oscillation to be used as power is sawed with electromagnetism.
The hand by shelf, saw blade, handle be made of relevant with the utility model sawed with iron at present.This iron saw adopts hand push, draw reciprocating realization of saw blade cut, so its physical labor intensity is big, effort, inefficiency.
The purpose of this utility model provides a kind of hand that adopts electric and magnetic oscillation to be used as power and saws with electromagnetism, with this manual labor amount that alleviates the operator, increases work efficiency.
The purpose of this utility model is achieved in that it comprises shelf, saw blade, handle, its technical essential is: but at shelf Motionless electromagnetic iron core and the motor magnet that overlaps coil is installed near handle one end, but the upper end of motor magnet constitutes hinge with wire spring and Motionless electromagnetic iron core to be connected, the lower end of electromagnetic core is provided with the installation back-moving spring, ejector pin, the support of adjusting knob, back-moving spring is enclosed within on the ejector pin, when in the coil that is enclosed within the Motionless electromagnetic iron core by through the electric current of halfwave rectifier the time, but the Motionless electromagnetic iron core is just inhaled motor magnet, when no current in the coil by the time (being operated between the half-wave of being pruned), fixed electromagnet does not have suction, but motor magnet then relies on back-moving spring and ejector pin with its forced back, but so go round and begin again motor magnet is moved reciprocatingly; The other end bottom of shelf is provided with the sleeve of guide post, guide pin, holddown spring being installed and being tightened screw, holddown spring is enclosed within on the guide post, have the guiding straight trough on this guide post, guide pin on the installing sleeve forces guide post can only do axial linear movement by the guiding straight trough, but thereby guarantee to be connected the straight of saw blade motion track between motor magnet and the guide post, tighten screw and holddown spring can make saw blade tighten by adjustment, avoid the vibration of saw blade with this.
The utility model is because to adopt electric and magnetic oscillation be that power drives saw blade and automatically moves back and forth and realize automatic cutting, so compared with prior art alleviated operator's manual labor greatly, and improved operating efficiency.
The utility model is described in further detail below in conjunction with accompanying drawing.
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model electrical schematic diagram.
With reference to figure 1, the utility model is made up of shelf, handle, saw blade, power source, guiding mechanism five parts.But shelf 1 is equipped with electromagnetic core 2 and motor magnet 3 near handle 10 1 ends, coil 4 is enclosed within on the electromagnetic core 2, but the upper end of motor magnet 3 constitutes hinge with wire spring 5 with electromagnetic core 2 to be connected, electromagnetic core 2 lower ends are provided with installs back-moving spring 7, ejector pin 6, adjusting knob 9, the support 10 of limit spring 8, when in the coil 4 during the electric current by after halfwave rectifier, electromagnetic core 2 produces suction, but inhale moving motor magnet 3, when no current in the coil 4 by the time (alternating current is operated between the half-wave zone of being pruned by rectifying tube D), electromagnetic core 2 does not produce suction, this moment, but motor magnet 3 was at back-moving spring 7, reset under the effect of ejector pin 6, so go round and begin again, but motor magnet 3 is moved reciprocatingly, but the amplitude of motor magnet 3 (being the size of displacement), but realize that by the pressure that adjusting knob 9 changes 8 pairs of motor magnets 3 of limit spring the amplitude of adjustment is between 5~10mm; The other end of shelf 1 bottom is equipped with guiding mechanism, this guiding mechanism by sleeve 14, guide post 13, guide pin 17, holddown spring 15, tighten knob 16 and form.Have guiding straight trough 18 on the guide post, under the guiding of guide pin 17, force guide post 13 can only do axial linear movement, thereby guarantee the straight of saw blade 11 movement locus.Adjustment tightens knob and relies on holddown spring can realize the tightening of saw blade prevented the vibration of saw blade 11 with this; But saw blade 11 is connected between motor magnet 3 and the guide post 13, colludes K switch with hand during work, but motor magnet 3 is just moving in the suction of electromagnetic core 2 and the effect of back-moving spring 7 under drive saw blade 11 and move reciprocatingly, realize cutting with this.Fig. 2 is an electrical schematic diagram of the present utility model, and D is a commutation diode among the figure, and K is a switch, and 2 and 4 represent electromagnetic core and coil respectively.

Claims (1)

1, a kind of hand is sawed with electromagnetism, it comprises shelf, saw blade, handle, it is characterized in that: but at shelf electromagnetic core and the motor magnet that overlaps coil is installed near handle one end, but the upper end of motor magnet constitutes hinge with wire spring and electromagnetic core to be connected, the lower end of electromagnetic core 2 is provided with the support that back-moving spring, ejector pin, adjusting knob are installed, and back-moving spring is enclosed within on the ejector pin; The other end of shelf bottom is provided with the sleeve of guide post, guide pin, holddown spring being installed and being tightened screw, and holddown spring is enclosed within on the guide post, and guide pin is stuck in the guiding straight trough that guide post has.
