Abstract
The utility model relates to a big-stick cogging mill machine core base which comprises a support rod (1). Through holes (2) are respectively arranged on the support rod (1) in a left-right mode. The through holes (2) are footstep-shaped. A pin (3) is inserted in each of the through holes (2), and a pin protrusion shoulder (4) is arranged at the position of upper middle portion of the outer circle face of the pin (3). According to the big-stick cogging mill machine core base, the pin protrusion shoulder is arranged on the outer circle face of the pin, so that after a cogging mill is used for a long time, the pin is not prone to abrasion, and is not prone to sliding in the through hole; a cogging mill machine frame is well fixed on a support plate, so that service life of the cogging mill machine core base is prolonged.
Description
Technical field
The utility model relates to a kind of big stick-means of intimidation roughing mill movement base, belongs to the steel smelting equipment technical field.
Background technology
In smelting iron and steel was produced, milling train was the equipment of realizing metal rolled process.
The milling train movement base is used for frame ﹐ being installed and being fixed on ground, bear the gravity of working stand and the Li Ju ﹐ that tumbles guarantees the precision of working stand installation dimension simultaneously, rolling-mill housing is by fixing with being connected of milling train movement base upper support bar inner peg, common pin is owing to being cylinder, after milling train service time is long, the pin wearing and tearing, can cause pin in through hole, to slide, rolling-mill housing well is fixed on the gripper shoe, thereby affects the service life of milling train movement base.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provides a kind of support bar inner peg to be difficult for the big stick-means of intimidation roughing mill movement base that slides.
The purpose of this utility model is achieved in that
A kind of big stick-means of intimidation roughing mill movement base comprises support bar, respectively is provided with a through hole about on the described support bar, is plugged with pin in the described through hole, is characterized in: be provided with a pin convex shoulder on the periphery of described pin.
A kind of big stick-means of intimidation roughing mill of the utility model movement base, its through hole is a step through-hole.
A kind of big stick-means of intimidation roughing mill of the utility model movement base, its pin convex shoulder are arranged on the position on the upper side, middle part of the periphery of pin.
Compared with prior art, the beneficial effects of the utility model are:
A kind of big stick-means of intimidation roughing mill of the utility model movement base, be provided with a pin convex shoulder on the periphery of its pin, therefore after milling train is grown service time, pin is not easy to wear, pin is difficult for sliding in through hole, rolling-mill housing well is fixed on the gripper shoe, thereby has improved the service life of milling train movement base.
Description of drawings
Fig. 1 is the front view of a kind of big stick-means of intimidation roughing mill of the utility model movement base support bar.
Fig. 2 is the top view of a kind of big stick-means of intimidation roughing mill of the utility model movement base support bar.
Fig. 3 is the structural representation of the pin of a kind of big stick-means of intimidation roughing mill of the utility model movement base support bar.
Among the figure:
Through hole 2
Pin convex shoulder 4.
The specific embodiment
Referring to Fig. 1, Fig. 2 and Fig. 3, the utility model relates to a kind of big stick-means of intimidation roughing mill movement base, it comprises support bar 1, respectively be provided with a through hole 2 about on the described support bar 1, described through hole 2 is a step through-hole, be plugged with pin 3 in the described through hole 2, the middle part of described pin 3 is provided with a pin convex shoulder 4 on the upper side, during installation, pin convex shoulder 4 can make pin 3 be stuck on the step surface of through hole 2, and because the diameter of pin convex shoulder 4 is larger, so milling train length service time can not cause pin 3 to slide milling train movement base long service life in through hole yet.
Claims (3)
1. big stick-means of intimidation roughing mill movement base, comprise support bar (1), respectively be provided with a through hole (2) about described support bar (1) is upper, be plugged with pin (3) in the described through hole (2), it is characterized in that: be provided with a pin convex shoulder (4) on the periphery of described pin (3).
2. a kind of big stick-means of intimidation roughing mill movement base according to claim 1, it is characterized in that: described through hole (2) is a step through-hole.
