Abstract

The utility model discloses a seizing claw applicable to tilting a multi-section casting blank. For requirements of tilting the multi-section casting blank, a concave cushion block is welded on an original tilting seizing claw, therefore, a tilting function of the newly-added wide-section casting blank can also be realized on the device so as to avoid redesigning and remanufacturing a tilting seizing claw mechanism; and moreover, the possibility of increased investment cost affecting production is avoided, so that the economic benefit is increased.

Description

A kind ofly adapt to the pusher dog that multibreak strand turns over steel

Technical field

The utility model relates to a kind of pusher dog that multibreak strand turns over steel that adapts to, and is specially in the tilting gear of billet caster, can adapt to the pusher dog device that multibreak strand turns over steel, belongs to metallurgy industry conticaster technical field.

Background technology

In the billet caster of metallurgy industry, tilting gear is a kind of ejection equipment commonly used, turns over the steel pusher dog and plays an important role turning in the steel process of tilting gear, and the parallelogram linkage pusher dog can realize steadily turning over steel.For multibreak strand, the strand that pusher dog and linkage need satisfy Breadth Maximum can successfully be risen on the high-order slide rail face from low level, and promptly strand has no to arrive desired location through the slide rail curved guiding surface with hindering; Yet for newly-increased wide section conticaster, owing to the width reason of strand, shown in accompanying drawing 1 and accompanying drawing 2; When strand does not hinder when the right pendulum of station I rises to the station II, but from the station II to the station III continue the right side lay out liter, when carrying out the transition to strand on the slide rail cambered surface, because strand is inconsistent with the left lower edge of slide rail cambered surface; Cause strand can't carry out the transition on the cambered surface of slide rail; Influenced the carrying out that turns over the steel action, certainly will increase cost of investment if design again, make and turn over steel pusher dog mechanism this moment; Maybe might influence production, reduce economic benefit.

To above reason, be necessary to design a kind of both adapted to common strand, also adapt to wide strand turn over the steel pusher dog, require simplely simultaneously, implement reliably and not to influence production, domestic still do not have disclosed technical scheme in this aspect or a bibliographical information.

Summary of the invention

The utility model purpose is the problem to background technology proposed; A kind of pusher dog device that multibreak strand turns over steel that adapts to is provided; Turn over the needs of steel for multibreak strand; Weld a protruding cushion block on the steel pusher dog original turning over, make newly-increased wide section casting blank also can on this device, realize turning over steel functional.

The technical scheme of the utility model is: a kind ofly adapt to the pusher dog that multibreak strand turns over steel, it is characterized in that: turn on steel pusher dog and the strand contact-making surface original, be welded with a steel plate projection.Its beneficial effect is: because the steel plate projection effect of welding on the pusher dog; Lay out when the strand right side and to be raised to when contacting with the cambered surface slide rail; Increased the height of wide section casting blank, made strand not interfere conflict, realized that it turns over steel functional with the slide rail curved guiding surface towards slide rail curved guiding surface one end; Simple and effective realization wide section casting blank turn over steel functional, satisfied the needs of producing.

Description of drawings

Accompanying drawing 1 turns over steel pusher dog mechanism structure sketch map for traditional strand;

Accompanying drawing 2 is strand and a cambered surface slide rail phase time sketch map in the accompanying drawing 1;

Accompanying drawing 3 is that this newly uses the new embodiment structural representation;

Sketch map when accompanying drawing 4 carries out the transition to the cambered surface slide rail for this is new with the new embodiment strand.

The specific embodiment

The utility model embodiment is further specified the mark in the accompanying drawing below in conjunction with accompanying drawing: 1-drive connecting rod, 2-follower link, 3-pusher dog, 4-strand, 5-cambered surface slide rail, 6-projection, 7-driven shaft, 8-driving shaft.

With reference to accompanying drawing 1, accompanying drawing 2, drive connecting rod 1, follower link 2, pusher dog 3, driving shaft 8, driven shaft 7 and be installed between two axles on the pusher dog and constitute parallel-crank mechanism, this parallel-crank mechanism is driven by driving shaft 7 and drive connecting rod 1; Lay out liter along the realization of circular arc path shown in the A right side among the figure; Thereby drive pusher dog 3 right sides and lay out liter, realize strand 4 is risen to the station II, rises to the station III again from the station I, strand is after station III place carries out the transition to cambered surface slide rail 5; The steel that turns over of promptly accomplishing one-period moves; After an action was accomplished, a parallel-crank mechanism left side was accommodated and is fallen, and pusher dog 3 is under parallel-crank mechanism drives; Drive station I, homing from the station III.

For common strand, when the right side was put to the station II, because strand 4 bottom righthand sides and cambered surface slide rail 5 are not conflicted, pusher dog 3 can continue the right side and lay out liter, thereby does not have influence on the transient process of strand 4 to cambered surface slide rail 5.When needs turn over steel when action to wide section casting blank, because strand 4 is when the station I rises to the station II, the bottom right of strand 4 is along just in time inconsistent with the lower left corner of cambered surface slide rail 5, and overslaugh this moment is laid out to the pusher dog 3 continuation right sides and is raised to the station III.

With reference to accompanying drawing 3, accompanying drawing 4; The utility model embodiment is the steel plate projection 6 of upper surface welding at pusher dog 3; On the right side lay out when being raised to station II and continuing rising when wide section casting blank 4 this moment; Because strand 4 and cambered surface slide rail 5 non-contraventions, make strand 4 can continue the right side smoothly and lay out and rise and carry out the transition on the cambered surface slide rail 5, realize turning over the steel action.

The utility model embodiment is through the method for simple welding steel projection; Be implemented on original tilting gear and can the steel that turn over of wide section casting blank be moved; Avoid designing again, make and turn over steel pusher dog mechanism, increase cost of investment and influence production possibility, increased economic benefit.

Claims

1. one kind adapts to the pusher dog that multibreak strand turns over steel, it is characterized in that: turn on steel pusher dog and the strand contact-making surface original, be welded with a steel plate projection.
