Description
Technical field
The utility model belongs to the auxiliary equipment field of milling train, especially relates to a kind of novel rolling mill cartridge device.
Background technology
In recent years, along with China's rapid economy development, the people's the level of consumption improves constantly, and has greatly promoted civil buildings, automobile and other industries flourish.The increasing that government also does one's utmost is to the dynamics of investment of capital construction.As the benefited industry in the upper reaches, steel industry has obtained great development, but also industry production efficient is had higher requirement simultaneously, and roll changing time is crucial to production efficiency.In the roll change process of milling train, cartridge device plays an important role, and a kind of automatic, reliable cartridge device is the basic assurance of fast roll changing.
In existing technology, the milling train cartridge device mainly comprises clamping plate 1 and clamping hydraulic cylinder 3 two parts, and is as shown in Figure 1; Clamping hydraulic cylinder 3 drives clamping plate 1 and clamps operation, and clamping plate 1 can not just change and change along with the Hooks coupling universal coupling sleeve, when the position of Hooks coupling universal coupling sleeve reduces or raises; Can produce the slit between clamping plate 1 and the Hooks coupling universal coupling sleeve; Enough clamping forces can not be provided, and when the roll homalocephalus got into the Hooks coupling universal coupling sleeve, the frictional force of wearing the roller generation may make sleeve produce axially-movable; Thereby can not well carry out the roll change operation, reduce production efficiency.
Summary of the invention
The problem that the utility model will solve provides a kind of automatic and reliable novel rolling mill cartridge device, is particularly useful for the situation that the Hooks coupling universal coupling sleeve just changes in the rolling mill assembly roll change process.
For solving the problems of the technologies described above; The technical scheme that the utility model adopts is: the novel rolling mill cartridge device, comprise clamping plate, sliding seat, clamping power set, guide channel plate, jacking power set, and guide channel plate is installed on the rolling-mill housing; Sliding seat is stuck on the guide channel plate; The jacking power set are fixed on the guide channel plate and with sliding seat and are connected, and clamp power set and clamping plate and are installed on the sliding seat, clamp power set and are connected with clamping plate.
Further, described clamping power set are the clamping hydraulic cylinder, and described jacking power set are the jacking hydraulic cylinder.
Further, described clamping hydraulic cylinder both sides are equipped with feather key.
Further, in the groove of described guide channel plate the seam card is installed.
Jacking Driven by Hydraulic Cylinder sliding seat goes up and down on guide channel plate, and during the sliding seat motion, the seam card is realized guiding, moves both vertically thereby sliding seat is done accurately; The clamping hydraulic cylinder is fixed on the sliding seat, along with sliding seat moves together, when sliding seat moves to correct position; The jacking hydraulic cylinder quits work; The clamping hydraulic cylinder starts, and drives the clamping plate motion, realizes the clamping of clamping plate and the operation of unclamping; Feather key is realized the guiding of clamping plate, and effectively prevents the generation of clamping plate sag.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme; Can be according to the height of Hooks coupling universal coupling sleeve, the position of adjustment sliding seat, thus drive clamping plate and clamp the power set motion; So that the clamping plate position is corresponding with Hooks coupling universal coupling sleeve position; Clamping plate and Hooks coupling universal coupling are combined closely, realize roll change operation reliably automatically, the utility model makes the roll change operation convenient; Have simple in structure, easy to maintenance, advantage such as processing cost is low.

Among the figure: 1, clamping plate; 2, sliding seat; 3, clamping hydraulic cylinder; 4, guide channel plate; 5, jacking hydraulic cylinder; 6, feather key
The specific embodiment
Like Fig. 2, shown in Figure 3; A kind of novel rolling mill cartridge device of the utility model comprises clamping plate 1, sliding seat 2, clamps power set, guide channel plate 4, jacking power set, and guide channel plate 4 is installed on the rolling-mill housing; Sliding seat 2 is stuck on the guide channel plate 4; The jacking power set are fixed on the guide channel plate 4 and with sliding seat 2 and are connected, and clamp power set and clamping plate 1 and are installed on the sliding seat 2, clamp power set and are connected with clamping plate 1.
In order further to optimize the performance of the utility model, described clamping power set adopt clamping hydraulic cylinder 3, and described jacking power set adopt jacking hydraulic cylinder 5.
Described clamping hydraulic cylinder 3 both sides are equipped with feather key 6, and the guiding of clamping plate is accomplished through feather key 6, and feather key can effectively prevent the generation of clamping plate sag.The seam card is installed in the groove of described guide channel plate 4, and the effect of seam card is the guiding that realizes sliding seat 2, moves both vertically thereby sliding seat 2 is done accurately.
The utility model when mounted; Get togather guide channel plate 4 and milling train transmission side frame handle with bolt, then sliding seat 2 is installed on the guide channel plate 4, load onto jacking hydraulic cylinder 5; Connect jacking hydraulic cylinder 5 and sliding seat 2, clamping hydraulic cylinder 3, clamping plate 1 are installed on sliding seat 2 at last.
The course of work of this instance: in use, when roll has carried out the car mill, bottom roll roll surface position reduces; In order to guarantee that roll surface is identical with the preceding roll surface of car mill; Just need be below roll pad, thereby the Hooks coupling universal coupling sleeve is risen, the center line of Hooks coupling universal coupling sleeve and previous clamping plate 1 center be not on same horizontal line; Clamping plate 1 need to rise, and could well clamp the Hooks coupling universal coupling sleeve.At this moment just need 5 work of jacking hydraulic cylinder, drive sliding seat 2 and move upward, thereby drive the clamping hydraulic cylinder 3 and clamping plate 1 motion on the sliding seat 2; When the center that moves to clamping plate 1 and Hooks coupling universal coupling sleeve center during at same horizontal line; Jacking hydraulic cylinder 5 quits work, and the clamping hydraulic cylinder 3 on the sliding seat 2 begins action, and 1 pair of Hooks coupling universal coupling sleeve of clamping plate is clamped; At this moment roll could be extracted the roll homalocephalus from the Hooks coupling universal coupling sleeve, carries out the roll change process; When changing new roll, when clamping plate 1 center was higher than Hooks coupling universal coupling sleeve center, jacking hydraulic cylinder 5 descended, and makes their centers on same horizontal line, and the clamping process to the Hooks coupling universal coupling sleeve is carried out in clamping hydraulic cylinder 3 motions then.Cartridge device in the past is after the Hooks coupling universal coupling sleeve changes; Chuck can not well be clamped the Hooks coupling universal coupling sleeve; Brought difficulty to roll change, this novel cartridge device has well solved the shortcoming of former device now, can well satisfy the roll change demand
More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
