Description

Alkaline battery powder ring forming core rod
Technical field
The utility model relates to a kind of alkaline battery powder ring forming core rod, belongs to the technical field of powder moulding mold.
Background technology
The stamping of powder moulding process is widely used in industry manufacture field such as powder metallurgy, pottery, magnetic material, pharmacy, and improving its die life, improving product property is the target that people lay siege to.
For the product that the type hole is arranged, usually it is core that the shaping work part that is called plug or core bar is arranged in its mould, it generally is made into integral type, as everyone knows, mould in use its workpiece core can slowly wear and tear, because the most serious final molding zone in mould, position of wearing and tearing can make the final molding spot size less than demoulding zone gradually, thereby product can be cracked when the demoulding, and this has influenced the useful life of mould and the quality of product.
Summary of the invention
The purpose of this utility model is to provide a kind of can improve die life, improve the alkaline battery powder ring forming core rod of the quality of powder compacting product, solved that existing to be used to make the powder moulding mold useful life with type hole short and influence problem such as product property.
Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: it comprises the core body, the end of described core body is formed with thread segment, the lower end of thread segment is formed with the minor diameter smooth section, described minor diameter smooth section lower end is formed with annular stopper, the diameter of described minor diameter smooth section is positioned at the external diameter of ring-like seam with the lower part less than the core body, the wear-resisting one-tenth jacket interference fits of hollow is on the minor diameter smooth section of core body, the lower end of wear-resisting one-tenth jacket contacts with annular stopper, be combined with nut on the described thread segment, the lower end of nut becomes the last end in contact of jacket and with axial compression location between wear-resisting one-tenth jacket and the core body with wear-resisting, the external diameter of described nut is smaller or equal to the external diameter of wear-resisting one-tenth jacket, and described wear-resisting one-tenth jacket is made by zirconia ultra hard ceramic material.The utility model be by can slowing down the rate of wear of the present utility model at the external sheathed wear-resistant sleeve of core, thereby can improve useful life of the present utility model; In addition the external diameter of nut is designed to the external diameter less than wear-resisting overcoat, the external diameter that makes the utility model demoulding zone is all the time less than the aperture of product endoporus, thereby avoided that the utility model cracks product in knockout course, guaranteed the quality of product.Wherein, owing to be greater than the anti-wear performance of nut as the anti-wear performance of the wear-resistant sleeve of forming area, so the rate of wear of nut is greater than the rate of wear of wear-resistant sleeve, thereby the external diameter of nut will be all the time less than the external diameter of wear-resistant sleeve, therefore, can not occur in whole useful life of the present utility model by as being the problem that the nut in demoulding zone causes product to be cracked.
As preferably, the length of the thread segment of described core body is greater than the length of nut, the lower end of thread segment axially sufficiently is pressed between nut and the ring-like seam thereby nut is overlapped wear-resisting moulding corresponding in the wear-resisting one-tenth jacket, guarantees the reliable assembling between wear-resistant sleeve and the core body.
As preferably, described nut equates that with the external diameter of wear-resisting one-tenth jacket the external diameter at all the other positions of nut is less than the external diameter of wear-resisting one-tenth jacket near the outer diameter of lower end.Wherein, nut outer wall lower end and the wear-resisting effect that becomes the isodiametric position of jacket can play transition when the demoulding, the position that external diameter is littler than the external diameter of wear-resistant sleeve then helps the demoulding more.
As preferably, the mating surface of described nut and core body thread segment and core body minor diameter smooth section become the mating surface of jacket to scribble solid ebonite stick with wear-resisting.Wherein, be coated with solid ebonite stick at the mating surface of female and core body thread segment and core body minor diameter smooth section and the wear-resisting mating surface that becomes jacket and can guarantee the reliability that cooperates between wear-resisting one-tenth jacket and the core body.
As preferably, described wear-resisting one-tenth jacket outer wall in vain down and on have a slight taper, the size of tapering is 1: 250-1: between 500.Wherein, convenient in wear-resisting one-tenth jacket outer wall formation one slight taper from bottom to top in stripping operation, the quality of assurance product.
As preferably, the external diameter of the external diameter of described nut and wear-resisting one-tenth jacket all is positioned at the external diameter of annular stopper with the lower part less than the core body.
As preferably, with the arc chord angle transition, concentrate between described annular stopper and the minor diameter smooth section thereby reduce stress.
Therefore, the utlity model has and to improve die life, improve the characteristics such as quality of powder compacting product.
