Abstract
The invention relates to a machine for treating the surface of a tool, in particular to a tap magnetic powder passivation machine comprising a base. A support and a motor are disposed on the base. Two suckers are arranged on two sides of the support respectively. The motor is connected with the suckers through belt pulleys. Magnetic passivation powder is adsorbed to each sucker. The magnetic passivation powder is the mixture of magnetic powder and abrasive powder. A tap is arranged between the two suckers and is disposed on a rotating rack. The tap magnetic powder passivation machine has the advantages that the thread profile of the tap is smoother, surface coarseness is lower, friction is lower, chip removal is smoother, and tool sticking risk is greatly reduced; defects of the edge of the tap are eliminated, the edge passivated by magnetic powder is smooth and neat, the defects such as burrs, sharp edges, sawteeth, notches and cracks are eliminated, the processed surface is smooth, the quality is high, and the service life of the tap is prolonged by more than three times; the machine is simple to operate, labor intensity is low for workers, magnetic powder treatment for the tap is uniform, and products are attractive.
Description
Technical field
In order to improve cutting-tool's used life, cutting effect and reduction cost, just need to 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, a kind of screw tap magnetic machine for inactivating particularly, screw tap through the magnetic Passivation Treatment after, 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 as checking, can see clearly that the screw tap cutting edge still has small defective under 100 times tool microscope in the situation of microcosmic, such as burr, sharp limit, sawtooth, open-minded tooth, crackle etc.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 the screw tap Fast Wearing and scraps.Therefore, through after the accurate grinding, need to carry out Passivation Treatment at screw tap to its thread tooth profile, it is smooth smooth with circular-arc cutting edge that original defective screw tap cutting edge is become, and 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 that sand grains 1 is coated on the cloth wheel 2, and cloth wheel 2 is contained on the abrasive machine 3, polishes by the surface of 1 pair of screw tap 4 of sand grains during 2 rotation of cloth wheel.Because sand grains 1 is coated on the cloth wheel 2 and can't accomplishes evenly, be again manual operations during polishing, the full armrest sense of polishing dynamics, particularly the screw thread profile is irregular, so polish inhomogeneous
,Also throw easily bad tooth form, labor strength is large, poor working environment.
The sand grains passivation is that sand grains 1 is put into emery disc 5, and screw tap 4 is inserted in the sand grains 1, by 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 space curved surfaces of a complexity, in the work because discontinuity, space curved surface on the screw tap can't be processed evenly, and particularly the cutting edge of screw tap can't be processed and be controlled at all uniformly and effectively, has therefore greatly affected cutting ability and the life-span of screw tap.
Summary of the invention
The objective of the invention is to 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 the inhomogeneous defective of sand grains passivation polishing.
The objective of the invention is to realize as follows: described screw tap magnetic machine for inactivating comprises base, base is provided with support and motor, the both sides of support respectively are provided with a sucker, motor is connected with sucker by belt pulley, adsorb the passivating powder that is magnetic on the sucker, the magnetic passivating 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 as follows:
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 widely sticking cutter risk.
2, eliminate the defective of screw tap cutting edge, cutting edge is round and smooth after the magnetic passivation, and polishing has been eliminated burr, sharp limit, sawtooth, tooth, crackle etc. the defective of slitting, and finished surface is bright and clean, and quality is high, and life of tap improves more than 3 times.Simultaneously, can carry out passivation to the multiple coating on screw tap surface, obtain meticulous little surface effect, life of tap 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, cone 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, greatly reduces the resistance in the cutting, processing moment reduces, and greatly improves service life.
5, the magnetic recoverable is pollution-free, good environmental protection.
