Detailed description of the invention
The purpose of this utility model is the pilot pin assembly that the purpose of this utility model is to provide a kind of automatic discharging, to solving in progressive die production process, and the problem of pilot pin band material, thus improve stamping parts quality and enhance productivity.
Please refer to Fig. 1, Fig. 2, in a kind of detailed description of the invention, the pilot pin assembly of the automatic discharging that the utility model provides comprises pilot pin 5, spring 4 and unloading block 6; One end of described pilot pin 5 is provided with taper chamfering 11, its other end is provided with the first boss 9, at described first boss 9, the end face of described taper chamfering 11 is provided with the second boss 10, the girth of described first boss 9 is greater than the girth of described second boss 10, and described first boss 9 and described second boss 10 are arranged in upper mould fixed plate pre-manufactured hole; Described spring 4 is sleeved on pilot pin 5, and the internal diameter of described spring 4 is greater than the external diameter of described pilot pin 5, the external diameter of described spring 4 is less than the external diameter of described second boss 10, and one end of spring 4 and described second boss 10 are fitted away from the end face of described first boss 9; Described unloading block 6 is sleeved on described pilot pin 5, and the 3rd boss 12 is provided with on the end face of described second boss 10, the external diameter of described 3rd boss 12 is greater than the external diameter of described spring 4, the other end and described 3rd boss 12 of described spring 4 are fitted near the end face of described second boss 10, described unloading block 6 is connected in the pre-manufactured hole of stripper 7, and described unloading block 6 length is greater than stripper 7 thickness.
In this structure, pilot pin 5 is arranged in the prefabricate and install hole on mold fixed head 3, pilot pin 5 and installing hole are matched in clearance, pilot pin 5 first boss 9 is parallel with mold fixed head 3 upper surface away from the second boss 10 end face, and end face is fixed on after installing upper padding plate 2 additional on upper bolster 1 on the upper mold; Unloading block 6 is arranged in the pre-manufactured hole on stripper 7, and it can slide by stripper 7 relatively, and spacing by the 3rd boss 12, spring 4 provides pressure source.Stripper 7 has unloading bolt and mould to want to be connected, and spring 4 passes pilot pin 5, between pilot pin 5 and unloading block 6.When upper/lower die separates, stripper 7 is positioned at bottom dead centre owing to being subject to the restriction of unloading bolt position, and unloading block 6 is positioned at bottom dead centre due to the effect of the power being subject to spring 4, contacts spacing by the hanging platform of unloading block 6 with stripper 7, exceeds stripper 7 by unloading block 6 bottom surface; In upper/lower die closing course, first pilot pin 5 contacts correcting with the correcting hole on material strip, continue descending pilot pin 5 to contact with the correcting pin-and-hole on counterdie 8, continue descending unloading block 6 to contact with material strip material strip is pressed on counterdie 8, continue descending, unloading block 6 relatively stripper 7 is slided, and spring 4 forced compression, continues descending holding pad and push down material strip; Continue to come downwards to mold closed condition, mould closes, the rear mold that worked is opened with lathe slide block is up, stripper 7 leaves material strip, the decrement continuing up spring 4 discharges gradually, and unloading block 6 relatively stripper 7 is slided, until pilot pin 5 upper end fillet part departs from correcting hole, 3rd boss 12 contacts with stripper 7, along with mold separates together.This structure, in the process of mould die sinking, effectively avoids the problem that pilot pin 5 is with material, thus enhances productivity, improve the quality of product.
It is to be appreciated that described pilot pin 5 is cylindrical structural, and described first boss 9 and described second boss 10 are cylindrical.This structure effectively ensure that the self-strength of pilot pin 5, thus improves the service life of pilot pin 5, and then reduces the cost manufactured.Certain pilot pin 5, first boss 9 and the second boss 10 can also adopt other versions such as cuboid as an alternative.
Further, described pilot pin 5 is Hardmetal materials.The selection of this material drastically increases the service life of pilot pin 5, and then reduces the cost of the manufacturing.Certainly the material that other intensity such as wolfram steel are higher can also be adopted as candidate materials.
Concretely, described unloading block 6 is high speed steel material, and described unloading block 6 is cylindrical structural, and described 3rd boss 12 is cylindrical simultaneously.In this structure, unloading block 6 adopts high-speed steel in order to increase the service life of unloading block 6, and then reduce the cost manufactured, unloading block 6 is for cylindrical structural is in order to increase self-strength, arranging of 3rd boss 12 plays spacing effect to unloading block 6 simultaneously, and the 3rd boss 12 shape also can be other shape as square etc.
It is pointed out that ordinal numbers such as " first, second, third " described in literary composition is the different structure in order to distinguish same names, only for convenience, not representing certain order, more should not be construed as any restriction.
Mode above only by illustrating describes some one exemplary embodiment of the present utility model, undoubtedly, for those of ordinary skill in the art, when not departing from spirit and scope of the present utility model, can revise described embodiment by various different mode.Therefore, above-mentioned accompanying drawing is illustrative with being described in essence, should not be construed as the restriction to the utility model claims.
