Embodiment Construction

[0009] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0010] As shown in the figure, there is a concave equilateral trapezoidal lower mold groove 4 on the top of the lower die 5, and the hypotenuse of the lower mold groove 4 is equal to the lower bottom edge; Side trapezoidal upper die groove 2, the hypotenuse of upper die groove 2 is equal to the upper bottom edge. The upper die groove 2 and the lower die groove 4 form a regular hexagonal die cavity.

[0011] When in use, put the hexagonal nut 3 into the lower die groove 4 and press down on the upper die 1, relying on the extrusion of the upper die groove 2 and the lower die groove 4, the diameter of the inner wire of the nut 3 is reduced, and the narrowing range can be adjusted by adjusting the upper die. The gap between die 1 and lower die 5 is realized.

Abstract

A nut correcting device is characterized in that a downward-sunken antiparallelogram lower die groove is formed in the upper face of a lower seat die, and the oblique edge of the lower die groove is equal to the lower bottom edge of the lower die groove; an upward-sunken antiparallelogram upper die groove is formed in the lower face of an upper pressing die, and the oblique edge of the upper die groove is equal to the upper bottom edge of the upper die groove; and an orthohexagonal die cavity is formed by the upper die groove and the lower die groove. The nut correcting device solves the problem that a nut no-go gauge does not stop and consequently waste is caused, and is particularly suitable for correcting a nut.

Description

technical field [0001] The invention relates to the field of machining tools, in particular to a mold for correcting hexagonal nuts. Background technique [0002] Nuts that are often used, due to poor mold workmanship and other reasons in production, some nuts do not stop when the go-no-go gauge inspection is performed. When the work requires that the nuts used must pass the go-no-go gauge inspection, these nuts cannot be used and become Substandard products cause waste. Contents of the invention [0003] The invention provides a device for correcting hexagonal nuts with non-stop nuts in order to solve the problem of waste caused by non-stop nuts. [0004] The technical solution of the present invention is a nut correcting device, which is special in that a concave equilateral trapezoidal lower mold groove is opened on the lower mold, and the hypotenuse of the lower mold groove is equal to the lower bottom edge; The lower side of the die is provided with a concave equila...
