Abstract

The utility model relates to a machine carrying out surface treatment on tools, in particular to a screw tap magnetic powder passivation machine. The screw tap magnetic powder passivation machine comprises a base seat. A support and a motor are arranged on the base seat, a suction disk is respectively arranged on each side of the support, and the motor is connected with the suction disks through a belt wheel. Magnetic passivation powders are attached on the suction disks and formed by mixing of magnetic powders and abrasive powders. Screw taps are arranged between the two suction disks and disposed on a rotary frame. The screw tap magnetic powder passivation machine can improve finish degree of thread molded surfaces of the screw taps, reduce surface roughness and friction and greatly reduce knife-sticking risks and enables scrap-discharge to be smooth. In addition, the screw tap magnetic powder passivation machine can eliminate defects of screw tap cutting edges, the cutting edges are smooth and finished after magnetic powder passivation, the defects of the burrs, sharp edges, sawteeth, broken teeth, flaws and the like are removed, finished surfaces are smooth and clean, quality is high and service life of the screw taps can be improved by more than three times. Thus, the screw tap magnetic powder passivation machine has the advantages of being simple to operate and even and uniform in screw tap magnetic powder passivation treatment effect, labor intensity of workers is low and products are attractive.

Description

Screw tap magnetic machine for inactivating
Technical field
For the service life, the cutting effect that improve cutter with reduce cost, just need carry out various surface treatments to cutter.Involved in the present invention is exactly a kind ofly carries out the surface-treated machine to cutter; Particularly a kind of screw tap magnetic machine for inactivating, screw tap be through after the magnetic Passivation Treatment, the surface quality that has improved; Its life-span and service efficiency also all improve a lot, and particularly life-time dilatation is the most remarkable.
Background technology
Screw tap is in manufacture process, and through accurate grinding, the thread tooth surface roughness reaches below the Ra0.4, and is very bright and clean.But its cutting edge like inspection under 100 times tool microscope, can see clearly that the screw tap cutting edge still has small defective under the situation of microcosmic, like burr, sharp limit, sawtooth, open-minded tooth, crackle or the like.These small defective naked eyes are difficult to identification, and these defectives are along with the screw tap prolongation of service time, and cutting edge can constantly wear and tear; Its defective can cause cutting edge place gap to extend, and tooth, the generation of tipping phenomenon are collapsed in the wearing and tearing aggravation; Cutting ability constantly descends, and causes fast wearing and tearing and scrapping of screw tap.Therefore, through after the accurate grinding, need carry out Passivation Treatment at screw tap to its thread tooth profile; Make original defective screw tap cutting edge become the circular-arc cutting edge of smooth band, like this, it is brisk that working angles will become; Surface of the work is just brighter and cleaner, and the life-span of screw tap just can be improved.
Existing screw tap passivation means are to adopt buffing and sand grains passivation (seeing Fig. 1 and Fig. 2).
Buffing is to be coated in sand grains 1 on the cloth wheel 2, and cloth wheel 2 is contained on the abrasive machine 3, polishes through the surface of 1 pair of screw tap 4 of sand grains during 2 rotations of cloth wheel.Because sand grains 1 is coated on the cloth wheel 2 and can't accomplishes evenly, again manual operations during polishing, the full armrest sense of polishing dynamics, particularly the screw thread profile is irregular, so polish inhomogeneous ,Also throw bad tooth form easily, labor strength is big, poor working environment.
The sand grains passivation is to put into emery disc 5 to sand grains 1, and screw tap 4 is inserted in the sand grains 1, through sand grains 1 passivation is carried out on its surface during the rotation of screw tap 4.Because the screw thread profile of screw tap 4 is complex spatial curved surfaces; In the work because discontinuity; Space curved surface on the screw tap can't be handled evenly, and particularly the cutting edge of screw tap can't be handled and controlled at all uniformly and effectively, has therefore greatly influenced the cutting ability and the life-span of screw tap.
Summary of the invention
The objective of the invention is to polish uneven defective, invent a kind of screw tap magnetic machine for inactivating that utilizes magnetic to come the passivation screw tap in order to overcome existing buffing and sand grains passivation.
The objective of the invention is to realize as follows: said screw tap magnetic machine for inactivating comprises base; Base is provided with support and motor, and the both sides of support respectively are provided with a sucker, and motor is connected with sucker through belt pulley; Be adsorbed with magnetic passivation powder on the sucker; Magnetic passivation powder is mixed by magnetic and grounds travel, and screw tap is located between two suckers, and screw tap is arranged on the swivel mount.
Good effect of the present invention is following:
1, improve the fineness of the screw thread profile of screw tap, reduce surface roughness 2-3 doubly, the screw tap surface roughness after the magnetic passivation is reduced to below the Ra0.2-0.1 by Ra0.4, reduces friction, and makes chip removal more smooth, reduces sticking cutter risk widely.
2, eliminate the defective of screw tap cutting edge, cutting edge is slick and sly after the magnetic passivation, and polishing has been eliminated burr, sharp limit, sawtooth, tooth, crackle or the like the defective of slitting, and finished surface is bright and clean, and quality is high, and the screw tap life-span improves more than 3 times.Simultaneously, can carry out passivation to the multiple coating on screw tap surface, obtain the surface effect of fine micro, the screw tap life-span improves more than 10 times.
3, easy and simple to handle, the process programme-control, labor strength is low, screw tap magnetic Passivation Treatment effect uniformity, product is attractive in appearance.
4, awl can improve coating adhesion through the magnetic Passivation Treatment; Screw tap after the coating after treatment, the removal coating scale makes the coating surface polishing, improves surface roughness, reduces the resistance in the cutting greatly, processing moment reduces, and greatly improves service life.
5, the recyclable utilization of magnetic, pollution-free, good environmental protection.

The specific embodiment
As shown in Figure 3, said screw tap magnetic machine for inactivating comprises base 6, and base 6 is provided with support 7 and motor 8; The both sides of support 7 respectively are provided with a sucker 9; Motor 8 is connected with sucker 9 through belt pulley 10, is adsorbed with magnetic passivation powder 11 on the sucker 9, and magnetic passivation powder 11 is mixed by magnetic and grounds travel; Screw tap 4 is located between two suckers 9, and screw tap 4 is arranged on the swivel mount 12.
During use, the good screw tap of clamping on swivel mount gets into screw tap and is filled in the sucker of magnetic passivation powder, and sucker is rotated by driven by motor, and magnetic passivation powder is rotation together thereupon then.Under the effect that two dimension is rotated, realize the Passivation Treatment even, accurate, controlled to screw tap.
