Abstract
The utility model relates to a connecting mechanism for a guide sleeve and a mould holder. The lower end of the guide sleeve is mounted in a hole in the mould holder in a hole and axle transition matching mode; a middle hole of a fixing plate passes through a guide sleeve part protruding from an upper plane of the mould holder and is fixedly mounted with the mould holder by using a bolt; a concave hole is formed in the middle of a lower plane of the fixing plate; two or more than two spring sheets with oppositely mounted openings are arranged in the concave hole; inner holes of the spring sheets are sleeved on an outer circle of the guide sleeve; the outer circles of the spring sheets are clamped and jointed on an inner circular plane of the concave hole; and one or more than one annular adjusting sheet is arranged on a lower port part of the concave hole. The connecting mechanism can overcome the defects of the prior art that a hole axle is not high in manufacturing precision and the quality is difficult to ensure.
Description
Technical field
The utility model relates to cold-punching mold, is specifically related to the bindiny mechanism of guide pin bushing and the die holder of cold-punching mold, belongs to the cold-punching mold technical field.
Background technology
As everyone knows, between the guide pin bushing on cold-punching mould and die holder, assembly connection mainly contains dual mode, 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 coordinates and cylindrical with the bindiny mechanism of die holder, and easily damage guide pin bushing and die holder when assembling, cause Quality Down even to 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 contraction of guide pin bushing excessive, mould and die accuracy is descended even scrap.
Summary of the invention
The purpose of this utility model is: for the guide pin bushing of existing cold-punching mold and the existing defects of bindiny mechanism of die holder, the utility model provides a kind of novel guide pin bushing and the bindiny mechanism of die holder, overcomes the existing defects of bindiny mechanism of existing guide pin bushing and die holder.
the technical scheme that the above-mentioned purpose that realizes the utility model 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 coordinates with the hole axle is arranged in hole on die holder, the guide pin bushing that the interstitial hole of fixed head passes plane on outstanding die holder partly with bolt together with die holder is fixed on, be shaped with shrinkage pool in the middle of the lower plane of fixed head, the spring leaf that oral area more than two or two is installed relatively is set in 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, annular trimmer more than one or one is set at the lower port position of shrinkage pool.
Beneficial effect: the utility model 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 prior art owing to matching and casting with the hole axle relation of interference between guide pin bushing and die holder existing in the method that low-melting alloy realizes locating: the hole axle accuracy of manufacture is high, quality is not easy with the defective that guarantees.
Description of drawings
Accompanying drawing is structural principle front view of the present utility model.
Shown in figure: 1, die holder; 2, fixed head; 3, bolt; 4, bowl type spring leaf; 5, guide pin bushing; 6, adjusting pad; 7, shrinkage pool.
The specific embodiment
the bindiny mechanism of a kind of guide pin bushing and die holder, it comprises: die holder (1), fixed head (2), bolt (3), bowl type spring leaf (4), guide pin bushing (5), adjusting pad (6), the mode that the lower end of guide pin bushing (5) excessively coordinates with the hole axle is arranged in hole on die holder (1), guide pin bushing (5) part that the interstitial hole of fixed head (2) passes outstanding die holder (1) upper plane with bolt (3) together with die holder (1) is fixed on, be shaped with shrinkage pool (7) in the middle of the lower plane of fixed head (2), the spring leaf (4) that oral area more than two or two is installed relatively is set in shrinkage pool (7), the inner hole sleeve of spring leaf (4) is connected on the cylindrical of guide pin bushing (5), the cylindrical of spring leaf (4) is connected on the inner headed face of shrinkage pool (7), annular trimmer (6) more than one or one is set at the lower port position of shrinkage pool (7), trimmer (6) gross thickness is relevant with the decrement of the short transverse of spring leaf (4), decrement is large, endoporus is also large to the chucking power of guide pin bushing (5).
Claims (1)
