Abstract

The utility model relates to a micro-electric energy mould grinder, which is composed of a micromotor, a belt roller, a machine base, a fixing casing, a flexible shaft, a flexible tube, a holding part and a movable supporting frame. The utility model is characterized in that the transmission in a mechanically flexible shaft type is adopted to replace the air pressure gun which adopts an air compressor of the prior art as motive power. The utility model has the advantages of energy saving, small noise, low cost, and easy use. The utility model is widely used for the producing, shaping, burnishing, and repairing of hot casting moulds, cold punching moulds, plastic mould, and various mould cavities. The utility model provides a new structure electric tool for mould making industry.

Description

Micro-electric energy mould grinder

Technical field is a mould manufacturing industry under the utility model.It relates to a kind of mold cavity manufacturing, shaping, polishing and repairs the particular manufacturing craft abrasive machine of usefulness.

In mould manufacturing processing, prior art is to drive " air pressure gun " with air compressor, and the emery wheel rotation on " air pressure gun " is finished the work.Though easy to use, flexible characteristic that this technology has.But because of using air compressor machine, defective is unavoidable, at first, air compressor motor power is generally more than 4～5.5 kilowatts, and function only is that to drive a maximum gauge be 30 millimeters emery wheel, is far longer than operating power, is quite waste and unmatched economically; The second, air compressor machine another name " air pump ", about 150 decibels of the Gao Keda of its noise, cause the serious abominable of working environment, cause many units, air compressor machine is shelved on outside the workshop for reducing the workshop noise, let alone to expose to the weather, caused the certain device loss to country; The 3rd, the air compressor machine price is very high, with the also raising thereupon of complete machine cost of its composition, therefore, and waste of electric energy, it is prior art that noise reaches the cost height greatly, the shortcoming that is difficult to overcome.

Task of the present utility model is to propose new version, overcomes the problem that prior art exists, and to reach energy savings, improves work situation, reduces the purpose of complete machine cost, and obtains and the prior art effect of working equally or better.

This mould abrasive machine is made up of motor, running part and grip portion (working portion), its essence is with mechanical cable type transmission to replace the gas transmission of " air pressure gun " and remove air compressor machine.Its concrete structure and the kind of drive are: micro machine (1) reaches support (3) after large and small belt pulley (2) speed change, reach flexible axle (7) through fixed cover (4) again, flexible axle (7) is given handle (8) with transmission of power, handle (8) front end is equipped with drill chuck, and with the forming grinding wheel of clamping different shape, flexible axle (7) is furnished with flexible pipe (6), in addition, this machine is furnished with appliance controller (5), and it comprises, power connection indicator lamp, gear selection switch and floor push etc.

Respectively have a square opening (30) (40) in the side of support (3) and the lower end of fixed cover (4), use during for installation flexible pipe (6) and flexible axle (7), unclamp the trip bolt of fixed cover (4) during installation, fixed cover (4) is up rotated an angle makes its lower end square hole (40) align with the hole, side (30) of support (3), so that operation goes back to the origin-location with fixed cover (4) after the installation again.One end of flexible axle (7) is fixed in the installing hole of power transmission shaft in the support (3) with trip bolt, the other end then is fixed in the installing hole of power transmission shaft in the handle (8), one end of flexible pipe (6) is fixed on the fixed cover (4), the other end is fixed on the handle (8), like this, flexible axle (7) can rotate in flexible pipe (6), and flexible pipe (6) does not change.Afterbody at fixed cover (4) and handle (8) respectively is equipped with a miniature bearing (41), makes flexible axle (7) in when work and bearing (41) run-in synchronism, to reduce the wearing and tearing of axle (7) and flexible pipe (6).This machine also is furnished with a travel(l)ing rest (9), gets final product in order to place grip portion, to pull it during use in work intermittently.

Because flexible axle is a revolving part, and flexible pipe matches with it, therefore, its cross section is all garden shape, and material can be selected spring steel (as 65 manganese spring steels), 60～70 for use ^#High-carbon steel etc. make it have certain amount of deflection (soft), with handled easily.

During use, required emery wheel is installed on the drill point of handle (8), start-up control device (5), electronic (1) reaches flexible axle (7) by belt pulley (2) with power, flexible axle (7) drives the emery wheel rotation, hand-held handle (8) can carry out grinding, and the flexible feasible operation of flexible axle flexible pipe is very convenient.

Owing to adopt new version, the utlity model has little power consumption, noise is little and cost is low characteristics.Its power of motor can be as small as 0.12～0.2 kilowatt, is 1/20th of prior art only, greatly reduces the loss of power, adopt the cable type transmission because of removing air compressor machine again, reduce noise, will improve workman's work situation greatly, also reduced the cost of complete machine simultaneously.This machine can be widely used in the manufacturing, shaping, polishing of hot forged mould, cold-punching mold, plastic mold cavity and repair and use, and can obtain and the air pressure gun effect of working equally even better.

Description of drawings.Fig. 1 is a complete machine drive mechanism floor map, and Fig. 2 is a travel(l)ing rest; (1) is micro machine, (2) be large and small belt pulley, (3) are support, and (4) are fixed cover, (5) be controller, (6) be flexible pipe, (7) are flexible axles, and (8) are handles, (9) be travel(l)ing rest, (40) be the fixed cover square hole, (30) are the support square hole, and (41) are miniature bearing.
