Abstract

The utility model discloses a modified cold -rolled ribbed bar rolling -mill roll axle, including roller, roller piece and nut, setting up positioning groove respectively in the axial outer fringe of roller and nut, the equipartition interval is setting up the stop plate in the roller piece outer peripheral edges, and wherein two stop plates are bent the card respectively and are gone into in the corresponding positioning groove. Utilize machinery locking, through the locking positioning groove of processing on roll axle and nut, the stop plate that sets up on the roller piece blocks respectively in the corresponding positioning groove to reach the locking purpose of nut, reduced the operation degree of difficulty.

Description

Improved cold-rolled ribbed steel bar rolling mill roll axle

Technical field

This utility model is related to a kind of improved cold-rolled ribbed steel bar rolling mill roll axle.

Background technology

Cold rolled reinforcing steel bar with ribs is applied quite varied in building trade.It is to be carried by processing hardening that cold rolled reinforcing steel bar with ribs produces The intensity of high reinforcing bar.Cold rolled reinforcing steel bar with ribs is collected as disk circle in production and processing.Cold rolled reinforcing steel bar with ribs Y type KT-2Y rolling mill roll axle It is the accessory of assembling cold rolled reinforcing steel bar with ribs roller piece, roller piece is pinned with nut after being assemblied in roll mandrel and prevents from loosening.But cold rolling strap Rib reinforcement Y type KT-2Y rolling mill roll axle, roller piece and nut, are integrated rotation when producing, and open because cold rolled reinforcing steel bar with ribs produces Dynamic frequent, nut is easily loosening under effect of inertia.Require for this in assembling by direction assembling, increased the behaviour of operator Make difficulty.

Content of the invention

The purpose of this utility model is to provide a kind of improved cold-rolled ribbed steel bar rolling mill roll axle, can solve the problem that nut Easily loosen problem, reduce the work difficulty of operator.

The purpose of this utility model is achieved in that a kind of improved cold-rolled ribbed steel bar rolling mill roll axle, including roller Axle, roller piece and nut, are respectively provided with detent in the axially outer edge of roll shaft and nut, uniform on roller piece outer peripheral edge Interval setting locking plate, and bending snaps in corresponding detent two of which locking plate respectively.

Locking using machinery, by locking detent is processed on roll mandrel and nut, the locking plate of setting on roller piece Being respectively clamped in corresponding detent, thus reaching nut anti-looseness purpose, reducing operation easier.

Brief description

Below in conjunction with accompanying drawing, this utility model is described in further detail.

Fig. 1 is main structure diagram of the present utility model；
