Abstract

The utility model relates to an electromagnetic percussive chisel used for the process such as sculpture, chiseling, picking, engraving, shoveling, etc. Of the artware such as metal, masonry, etc. The utility model comprises a sleeve barrel, a hammer, movable iron, electromagnets, and an impact bar. The two electromagnets are alternately energized and alternately suck the movable iron in the positive and negative half cycle of the commercial power, so the hammer can do seesaw motion with the frequency of 50 Hz in the sleeve barrel. The impact bar can be given the impact force with the same frequency and can process the workpieces through a working head arranged in the bottom barn hole. The utility model can replace a chisel, a hand hammer, and a minitype air-operated percussion tool, having the advantages of simple structure, high percussion frequency, high process efficiency, and low noise.

Description

Electromagnetic percussive chisel

The utility model relate to a kind of be used for to metal, masonry and handicraft carve, cut a hole, pick, carve, the instrument of processing such as shovel.

In the prior art, it mainly is manual operations that metal, masonry and handicraft are processed, and employed instrument mainly is chisel and hand hammer, and the processing work efficiency is low and labour intensity is big.In order to improve work efficiency, reduce labour intensity, also have the Pneumatic immpacting instrument that adopts, promptly adopt compressed air to produce Pneumatic immpacting and finish aforesaid operations.The Pneumatic immpacting tool equipment is numerous and jumbled, mobility is poor, and especially the noise pollution of air compressor is very serious.

The purpose of this utility model is a kind of electromagnetic impact instrument of design, finishes the work efficiency of above-mentioned processing and avoids the noise pollution of air compressor effectively with raising.

To achieve these goals, the utility model makes two E type electromagnet alternate energisations in the positive-negative half-cycle of civil power to dress also alternately inhale moving iron, thereby make electric energy be transformed into mechanical energy, and the impact bar that adopts energy-stored spring to make to have working head obtain the impulsive force of 50HZ and finish processing to workpiece.Be described in further detail below in conjunction with the technical characterictic of specific embodiment the utility model electromagnetic impact cutter.

Accompanying drawing 1 is the structural representation of electromagnetic impact cutter;

Accompanying drawing 2 is the electromagnet power supply circuit diagram.

With reference to the accompanying drawings 1,2, the utility model electromagnetic impact cutter mainly is made up of sleeve 1, tup 2, moving iron 3, electromagnet L1 and L2, impact bar 4.Sleeve 1 is a cylindrical shape, has a slotted hole on its waist barrel, and its top has one handle 5.Tup 2 is cylindrical, is installed in the sleeve 1 also can pump therein, and an energy-stored spring 6 is equipped with in going up between top and the sleeve top of tup 2, and the slotted hole corresponding position on the waist of tup 2 and sleeve 1 barrel has an oblong aperture.Moving iron 3 is made of the folded folder of silicon steel sheet steel plate for having the strip of tapering, and the one end has a round end plate 7 and passes sleeve 1 barrel and is installed in the tup 2 waist oblong aperture; The round end plate can slidably reciprocate in oblong aperture.Electromagnet L1 and L2 are E type electromagnet, are mounted on relatively on the sleeve and handle of moving iron both sides about in the of 3, and its outside two side columns are clamped an end of moving iron 3.Electromagnet L1 and the L2 energising alternately in parallel in the positive-negative half-cycle of civil power via two backward dioded D1 and D2 respectively, power switch K and diode D1, D2 are installed on the sleeve handle 5.Impact bar 4 is a round bar, and the lower end that is installed in sleeve 1 by pressure spring cover 9 also can pump in the pressure spring cover; Under static state, between the going to the bottom of the upper end of impact bar 4 and tup 2 1～1.5 mm clearance is arranged, the lower end of impact bar 4 has a hole, storehouse 8 that is used for the installment work head.

When connecting power switch, electromagnet L1 and L2 are at the positive-negative half-cycle alternate energisation and alternately inhale moving iron, and moving iron drives tup working frequency in sleeve under the effect of electromagnet be the double vibrations of 50HZ.Energy-stored spring energy storage and discharge when upper half at lower half, thus make impact bar obtain the impulsive force of same frequency.Exerting pressure by handle to make make progress jack-up and contact with tup of impact bar, changes the size of the controlled amount system impulsive force of exerting pressure.

The utility model is simple in structure, and frequency of impact height and noise level is low can replace chisel, hand hammer and miniature pneumatic percussion tool that metal, masonry and handicraft are processed.
