Abstract
The invention relates to the technical field of metallurgy rolling, in particular to a cross-shaped universal shaft bracket which is used for a rod and wire rolling mill. The cross-shaped universal shaft bracket comprises a bracket body, wherein two vertical bracket boards are arranged on the bracket body in a symmetrical mode. An upper cross-shaped universal shaft and a lower cross-shaped universal shaft are installed between the two bracket boards. The two cross-shaped universal shafts are in connection through a link mechanism. Trunnions are respectively arranged on two sides of each cross-shaped universal shaft. Each trunnion is inserted into an inner hole of a sliding block and connected with the sliding block. Each sliding block is embedded inside two sliding grooves, wherein the two sliding grooves are formed in the two bracket boards in an opposite mode and matched with the sliding blocks. A location mechanism is arranged between the trunnions and the sliding blocks. According to the cross-shaped universal shaft bracket, the cross-shaped universal shafts are always kept horizontal under conditions of different opening degrees, and achieving changing rollers quickly is ensured, and multiple potential safety hazards are avoided.
Description
Technical field
The present invention relates to the metallurgy rolling technical field, relate in particular to a kind of for the high cross universal spiale carriage of the roll change efficient of bar wire rod rolling mill.
Background technology
Pass to roll by universal-joint spindle after the most of short stress path rolling mill that adopts high rigidity of domestic excellent wire rod production line, the power of motor slow down through gear-box and complete the operation of rolling.The Main Function of universal spindle carrier is the weight of balance universal-joint spindle, guarantees that the torque of motor passes to roll stably, realizes steadily rolling.Because bar wire rod rolling mill adopts integral movement roll change method, namely roll and frame are changed together.Needing first old roller homalocephalus end to be pulled out rear movement integral body from the universal-joint spindle axle sleeve during roll change hangs between grinding roller, again ready new movement is packed into (new roller homalocephalus end is packed in the universal-joint spindle axle sleeve), so roll change process length consuming time directly affects on-the-spot production efficiency.Therefore, the spindle carriage is mainly used in guaranteeing the steadily reliable of universal-joint spindle running; The smooth dismounting of roll and universal-joint spindle axle sleeve and packing into during roll change realizes fast roll changing.
The structure of at present more common excellent wire rod spindle carriage forms: the support body on the spindle bracket body each side is equipped with a pair of upper and lower slide block, connect by connecting rod between upper and lower slide block, utilize lever principle, realize slide block linkage from top to bottom in support body, and upper and lower cross universal spiale is contained in respectively in the endoporus of upper and lower slide block by himself two gudgeons, realize the spindle carriage when different openings is spent, balance is the weight of cross universal spiale up and down.But the stressed sketch of cross universal spiale shown in from the accompanying drawing 3 can be found out, cross universal spiale is due to himself weight distribution inequality, the gravity at G2 place is much larger than the G1 place, there is the nose phenomenon in the cross universal spiale axle sleeve that causes joining with roll, such nose problem causes very large difficulty for on-the-spot fast roll changing, waste the plenty of time, and then restricting the raising of production efficiency.Herein axle sleeve also might be bowed downwards in addition, pipe arrangement on the machine that is easy to destory the scene, and impact is normally produced.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of for the high cross universal spiale carriage of the roll change efficient of bar wire rod rolling mill.
for solving the problems of the technologies described above, the invention provides a kind of cross universal spiale carriage, comprise bracket body, be symmetrically arranged with two vertical carrier frame plates on described bracket body, be equipped with between described two carrier frame plates, lower two cross universal spiales, described two cross universal spiales connect by link gear, described each cross universal spiale both sides are respectively equipped with a gudgeon, described each gudgeon inserts respectively in the endoporus of a slide block and is connected with described slide block, described each slide block embed respectively relatively offer on two carrier frame plates with suitable two chutes of described slide block in, be provided with location structure between described slide block and gudgeon.The present invention is by directly arranging location structure to slide block and cross universal spiale gudgeon, limited rotatablely moving of cross universal spiale and slide block cooperation place, make the cross universal spiale that coordinates with roll in the situation that different openings degree maintenance level always, assurance realizes fast roll changing, and can avoid many potential safety hazards.
As preferably, described location structure is the positioning key that is arranged in the endoporus of described slide block, and described gudgeon and described positioning key relevant position offer locating notch.This structure manufacturing and install more convenient, good positioning effect.
As preferably, described positioning key is two, is symmetricly set on the both sides of described gudgeon.This structure improves locating effect.
As preferably, described slide block is two groups, is comprised of a top shoe and a sliding block of being positioned on the same carrier frame plate respectively, and described link gear is two groups, is connected with two cross universal spiales by one group of slide block respectively.This structure make upper and lower cross universal spiale respectively with upper and lower slide block mix proportion one cover lever balance system, no matter be under any opening degree, the deadweight of upper and lower cross universal spiale is mutual balance as system's internal force all the time, and both gravity is delivered to the support body of spindle carriage together by connecting rod, upper and lower cross universal spiale stressed more balanced, whole system is more stable.
As preferably, described link gear comprises the short connecting rod that is connected with top shoe and the long connecting rod that is connected with sliding block, described short connecting rod is positioned at the carrier frame plate inboard, and described long connecting rod is positioned at the carrier frame plate outside, and described short connecting rod is connected the balanced lever that a fulcrum is positioned at carrier frame plate top and connects with long connecting rod.This structure is easy for installation, and volume is little, and is effective.
The present invention is to have limited rotatablely moving of cross universal spiale and slide block cooperation place with respect to the beneficial effect of prior art, make the cross universal spiale that coordinates with roll in the situation that different openings degree maintenance level always, assurance realizes fast roll changing, has avoided many potential safety hazards.And the scene can compensate the error that the spindle carriage is made and installed by the reconditioning location structure, can be according to different operating modes, make each cross universal spiale that different micro angle swinging scopes be arranged, when guaranteeing that positioning key is subjected to very little shearing force, realize fast roll changing, enhance productivity.
