Embodiment Construction

[0035] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below. All other implementations obtained below fall within the protection scope of the present invention.

[0036] figure 1 is a schematic diagram of the nut two-way locking device; figure 2 is the top view of the nut two-way locking device, figure 2 The drive mechanism and shoulders are not shown. like figure 1 , figure 2 As shown, the nut two-way locking device (hereinafter referred to as the locking device) provided in this embodiment is used to clamp the accessory on the shaft. The locking device includes a shaft shoulder 9, a lock nut, a driving mechanism and a fixing mechanism . Wherein, the shaft shoulder 9 is arranged in the middle of the shaft, and the two ends of the shaft are respectively provided with external threads suitable for lock nuts, and a lock nut is res...

Abstract

The invention provides a bidirectional nut locking device and a combined roller. The bidirectional nut locking device is used for clamping accessories on a shaft and comprises a shaft shoulder, locking nuts, a driving mechanism and a fixing mechanism; the shaft shoulder is arranged in the middle of the shaft, and the locking nuts are arranged at the two ends of the shaft; the driving mechanism isused for driving the locking nuts to lock and sleeve the accessories on the shaft on the two sides of the shaft shoulder; and the fixing mechanism is connected with the shaft shoulder. Compared with the prior art, the locking device has the characteristics of high efficiency, simple and reliable structure, long service life and low cost, and is particularly suitable for application occasions witha narrow locking space for multi-slitting rolling of copper bars; and the combined roller adopts bidirectional locking to share the axial jacking force, so that the single-side minimum jacking force is reduced by 40%, the reliability of assembling the combined roller is greatly improved, and therefore the working capacity of the combined roller under the condition of the narrow designed locking space is improved.

Description

[0001] Cross References to Related Applications [0002] This application claims the priority of the Chinese patent application CN202010849062.5 entitled "A Nut Two-way Locking Device and Combined Roller" filed on August 21, 2020, and the entire content of the above application is incorporated herein by reference. technical field [0003] The invention relates to the technical field of roll shaft processing, in particular to a nut bidirectional locking device and a combined roll. Background technique [0004] Carbide combination rolls are usually used in the rolling of high-strength, shock-resistant, special steel materials such as round bars and rebars. Utilize the good thermal conductivity, good red hardness, good thermal fatigue resistance, good wear resistance, high strength and other characteristics of cemented carbide, and develop cemented carbide as the material of the outer layer of the roll. The combination of cemented carbide outer layer and high-toughness roller...
