Problems solved by technology

However, the existing screw nuts are generally castings, which have low strength and high brittleness, and require frequent replacement of new nuts, which is time-consuming and labor-intensive, and there is a great potential safety hazard. Unimaginable damage, therefore, the requirements for the strength and bearing capacity of the screw nut itself are more stringent

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings.

[0024] See attached Figure 1-4 , The lead screw nut disclosed in the present invention is used for adjusting and connecting building lead screws, and includes a circular platform 11 , side ears 12 and a tapered threaded barrel 13 in an integral structure. The screw nut is stamped from waste iron plate. And the circular platform 11 of the nut, the side ear 12 and the tapered threaded cylinder 13 are integrally structured, wherein a concave circular concave surface is arranged on the circular platform.

[0025] The lead screw nut is made according to the following steps:

[0026] a. Cut large pieces of waste iron plates into iron plates of appropriate size for later use;

[0027] b. Use a shape mold to punch out the circular table top and the outer contour blank of the side ear of the screw nut on the iron plate, that is, the structure of the plate-shaped circular ta...

Abstract

A lead screw nut comprises a circular table top, a side lug and a conical threaded barrel which are of an integral structure, and the lead screw nut is formed by stamping a waste iron plate. The lead screw nut is manufactured according to the steps: cutting a large waste iron plate into an iron plate of a proper size for standby application; punching outline blanks of the circular table top and the side lug of the lead screw nut on the iron plate by using an outline mould; heating the outline blanks at the temperature of 700-800 DEG C; placing the heated outline blanks on a punch and punchingthe circular table top and the conical barrel by using an inner barrel mould; and machining an internal thread on the inner wall of a conical tube by using a threading machine to complete manufacturing. The lead screw nut made of the waste iron plate is low in manufacturing cost and convenient in operation, the manufacturing method is simple and easily understood, and on the basis of ensuring theuse effect and the use strength of the nut, the bearing capacity of the nut is improved, and the service life of the lead screw nut is prolonged.

Description

technical field [0001] The invention relates to a connecting piece used in the construction field, in particular to a lead screw nut and a manufacturing method thereof. Background technique [0002] In the process of building construction, a large number of lead screws are required to connect and fix the upper and lower floors, and the connection and position adjustment between the lead screws are all realized by lead screw nuts. However, the existing lead screw nuts are generally castings, which have low strength and high brittleness, and require frequent replacement of new nuts. Therefore, the requirements for the strength and bearing capacity of the screw nut itself are more stringent. Contents of the invention [0003] The present invention aims at the defects existing in the existing lead screw nuts. One is to provide a lead screw nut with simple manufacture and high strength; . [0004] The technical solution adopted to achieve the above purpose is: a screw nut, w...
