Abstract
The invention relates to a seven-tooth output shaft mold which comprises an upper mold body, a middle mold body and a lower mold body which are sequentially arranged from top to bottom. The upper mold body comprises an upper punch and an upper inner punch body arranged in the upper punch. A tooth mold is arranged at the bottom end of the upper punch. The lower mold body comprises a third lower punch which is located in a second lower punch base. A second lower punch is further arranged in the second lower punch base. An upper punch hole matched with the upper punch and a lower punch hole matched with the third lower punch are formed in the middle mold body. A seven-tooth output shaft manufactured through the mold is high in accuracy and attractive in appearance, the tooth surface is smooth, secondary machining is not needed, and materials and labor are reduced.
Description
Technical field
The present invention relates to a kind of mould, especially relate to a kind of seven tooth output shaft moulds.
Background technology
Seven tooth output shafts are the parts be applied on automobile, and the production of existing seven tooth output shafts all adopts traditional cold heading technique, cause seven tooth output shaft surfaces crude, and unsightly, and the precision of output shaft does not reach requirement to profile, needs secondary operations, wasting manpower and material resources.
Summary of the invention
The present invention is intended to address the aforementioned drawbacks, and provides the seven tooth output shaft moulds that a kind of machining accuracy is high.
In order to overcome the defect existed in background technology, the technical solution adopted for the present invention to solve the technical problems is: a kind of seven tooth output shaft moulds, comprise the patrix set gradually from the top down, middle mould and counterdie, described patrix comprises upper punch and is arranged on the upper interior punching in upper punch, described upper punch bottom is provided with tooth mould, described counterdie comprises Xia Sanchong, described lower three punchings are arranged in following two punch base, also be provided with following two punch in described lower secondary base, be provided with the upper punching of mating with upper punch in described middle mould and rush the lower punching of mating with lower three.
In a preferred embodiment of the present invention, outside following two punch, be arranged with following two punch base cover plate.
The invention has the beneficial effects as follows: the seven tooth output shaft precision that this Making mold goes out are high, good looking appearance, and tooth surface is smooth, without the need to carrying out secondary operations, saving material, using manpower and material resources sparingly.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention;
Fig. 2 is sectional view of the present invention.
Detailed description of the invention
A kind of seven tooth output shaft moulds as depicted in figs. 1 and 2, comprise the patrix 1, middle mould 2 and the counterdie 3 that set gradually from the top down, the upper interior punching 5 that patrix 1 comprises upper punch 4 and is arranged in upper punch 4, upper punch 4 bottom is provided with tooth mould 6, counterdie 3 comprises lower three punchings 7, described lower three punchings 7 are arranged in following two punch base 8, be also provided with following two punch 9, be provided with the upper punching 10 of mating with upper punch 4 and rush the 7 lower punchings 11 of mating with lower three in middle mould 2 in lower secondary base 8.
Be arranged with following two punch base cover plate 12 outside following two punch 9, when using following two punch by following two punch base detachable cover plate, when not using following two punch, following two punch bottom cover plate can play the effect of protection following two punch.
Produce seven tooth output shafts with the cold heading technique before mould replaces, make the precision of seven tooth output shafts high, good looking appearance, without the need to secondary operations, uses manpower and material resources sparingly, and is adapted to extensive operation.
