Abstract
The utility model relates to a die, in particular to a cemented carbide ball gear for mining, which belongs to the self-pressing die formed through pressing. The die consists of an upper punch, a lower punch and a die sleeve, wherein the upper punch is flatly pressed on the die sleeve, and the spherical surface of the upper punch is not provided with a sharp edge. As the ordinary principle of counter pressure between the upper punch and the lower punch is changed into the flat pressure principle with the movement of the die sleeve, and the spherical surface of the upper punch has no sharp edge, thereby the utility model overcomes the defects of the pressurized lamination of the product and the short service life of the die, the formed ball gear has no lamination or crack, and the die can be used for more than 80,000 times.
Description
Technical field
The utility model relates to a kind of mould, and particularly a kind of mine hard alloy ball tooth belongs to compression moulding from the pressing mold tool.
Technical background
Mould is a necessary tool in a kind of CEMENTED CARBIDE PRODUCTION, and the quality of mould structure and reasonability not only have influence on the suppression performance of product, but also have influence on compacting efficient, the more important thing is the quality that has influence on product and the life-span of mould itself.
The ball tooth is a kind of mining instrument, and consumption is big, and each production lot is generally between 20,000 to 80,000.Because it is big in batches, generally all adopt mo(u)ldenpress mould press forming, the ball tooth shaping dies of Cai Yonging as shown in Figure 1 in the past, it is by upper punch, die sleeve and low punch are formed, the major advantage of the mould of this kind structure is simple in structure, easy to mould, its shortcoming is that the upper punch sphere has sharp edge, sphere and cylinder faying face that compression moulding is generated easily produce layering, and its sphere may cause in the oxygen welding or the course of work and come off, and another shortcoming is, because this kind structure mold upper punch sphere has sharp edge, behind general compacting 4000 to 7000 moulds, its sharp edge can come off or split, and mould can not be worked on.
Summary of the invention
The purpose of this utility model just provides a kind of a kind of ball tooth that overcomes problems of the prior art and design and develop from being pressed into pattern.
The technical solution of the utility model realizes that by following approach it is made up of upper punch, low punch and die sleeve, and wherein, the upper punch concora crush is on die sleeve, and the upper punch sphere does not have sharp edge.
The utility model is owing to making conventional last low punch the upper punch sphere no longer include sharp edge to the concora crush principle of pressing principle to change the die sleeve motion into, thereby product compacting layering and short shortcoming of mould self life-span have been solved, ball tooth after the moulding does not have layering, seminess, and the life-span of mould itself to surpass 80,000 moulds, the mould that facts have proved this kind structure is reasonably advanced.

Fig. 2 is for improving back ball tooth forming die structure schematic diagram.
Wherein: upper punch 1, low punch 2, die sleeve 3, sharp edge 4, core rod 5
The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing.
As shown in Figure 2, the utility model is made up of upper punch 1, low punch 2 and die sleeve 3, and wherein, upper punch 1 concora crush is on die sleeve 3, and the upper punch sphere does not have sharp edge 4.Die sleeve 3, core rod 5 and upper punch sphere are all made by carbide alloy, its objective is to reduce frictional resistance and improve wear-out life.Upper punch 1 concora crush moves together with die sleeve 3 on die sleeve 3 in the course of the work, makes product compression moulding.The major advantage of this structure: make conventional last low punch the upper punch sphere no longer include sharp edge to pressing principle to change the concora crush principle of die sleeve motion into, thereby solved product compacting layering and short shortcoming of mould self life-span.
Claims (1)
1, a kind of mould, it contains upper punch (1), low punch (2) and die sleeve (3), it is characterized in that described upper punch (1) concora crush is on die sleeve (3).
