Abstract
The invention discloses a connecting mechanism for a guide sleeve and a die holder; by the connecting mechanism, the lower end of the guide sleeve is arranged in a hole on the die holder in hole-shaft interference fit mode, a middle hole of a fixing hole passes through a part of the guide sleeve, which protrudes the upper plane of the die holder, and then the fixing plate is fixed with the die holder by a bolt; a concave hole is arranged in the middle of the lower plane of the fixing plate; at least two leaf springs, of which the mouth parts are opposite to each other in arrangement, are arranged in the concave hole; the inner hole of each leaf spring is sleeved on an outer circle of the guide sleeve; the outer circle of each leaf spring is blocked on the inner circle surface of the concave hole; the lower port part of the concave hole is provided with at least one ring-shaped adjusting sheet. The connecting mechanism can overcome the defects in the prior art that the hole-shaft manufacturing precision is high, and the quality cannot be ensured easily in the prior art.
Description
Technical field
The present invention relates to cold-punching mold, be specifically related to the bindiny mechanism of guide pin bushing and the die holder of cold-punching mold, belong to the cold-punching mold technical field.
Background technology
As everyone knows, assembly connection mainly contains dual mode between the guide pin bushing on the cold-punching mould and the die holder, and the one, match with the hole axle relation of interference; The 2nd, and closely spaced hole axle matching relationship, and the casting low-melting alloy is realized the purpose that is positioned to fix between the gap that forms between the hole face of the periphery of guide pin bushing and die holder.
Can be found out with the bindiny mechanism of die holder by existing guide pin bushing: guide pin bushing adopts the method for interference fit to require to have the higher accuracy of manufacture between the endoporus that cooperates and the cylindrical with the bindiny mechanism of die holder, and when assembling, easily damage guide pin bushing and die holder, cause Quality Down even scrap, and the bindiny mechanism that adopts the casting low-melting alloy, because low-melting alloy cold rises, amount of contraction is wayward, so, also easily cause the endoporus of guide pin bushing to shrink excessive, mould and die accuracy is descended even scrap.
Summary of the invention
The object of the invention is to: for the guide pin bushing of existing cold-punching mold and the existing defects of bindiny mechanism of die holder, the invention provides a kind of novel guide pin bushing and the bindiny mechanism of die holder, overcome the existing defects of bindiny mechanism of existing guide pin bushing and die holder.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: the bindiny mechanism of described a kind of guide pin bushing and die holder, it comprises: die holder, fixed head, bolt, bowl type spring leaf, guide pin bushing, adjusting pad, it is characterized in that: the mode that the lower end of guide pin bushing excessively cooperates with the hole axle is installed in the hole on the die holder, the guide pin bushing that the interstitial hole of fixed head passes plane on the outstanding die holder partly is fixed on die holder with bolt, in the middle of the lower plane of fixed head, be shaped with shrinkage pool, the spring leaf that oral area more than two or two is installed relatively is set in the described shrinkage pool, the inner hole sleeve of described spring leaf is connected on the cylindrical of guide pin bushing, the cylindrical of described spring leaf is connected on the inner headed face of shrinkage pool, and the annular trimmer more than or is set at the lower port position of shrinkage pool.
Beneficial effect: the present invention by spring leaf in when compression, the method that diameter of bore shrinks, guide pin bushing and die holder are fixed, and can overcome in the prior art owing to matching and casting existing in the method that low-melting alloy realizes locating between guide pin bushing and the die holder with the hole axle relation of interference: the hole axle accuracy of manufacture is high, quality is not easy with the defective that guarantees.
