Abstract
The utility model relates to a device is demolishd to spinning head. The device comprises a baffle plate, a baffle plate screw and a jackscrew; the baffle is provided with two screw holes which are in clearance fit with the baffle screws, and the center distance of the two screw holes is the same as that of the adjacent counterweight threaded holes on the spinning head; the diameter of the jackscrew is the same as that of a fixing bolt of a hollow shaft on the laying head body, and the length of the jackscrew is 40mm, 120mm longer than that of the fixing bolt; the thread parameters of the baffle plate screw are the same as the counterweight threaded hole of the laying head. The device has simple structure and can quickly and easily replace the laying head.
Description
Technical Field
The utility model relates to a device for removing a spinning head, which is particularly suitable for removing the spinning head of a Danieli series spinning machine.
Background
The laying head is a indispensable device for high-speed wire production, and has the functions of 'laying' high-speed wires into a ring and placing the ring on a bulk-coil transportation cooling line, a laying head component on the ring is a component which is directly contacted with a high-speed high-temperature rolled piece, belongs to a process wearing part and needs to be replaced after a certain yield is reached, but when the laying head of the Daniely series is used for replacing the laying head, the laying head and a hollow shaft spigot matching hole on a laying head body are phi 540H6/m6, and are in tight transition matching, so that the disassembly is difficult, and in addition, the laying head is also provided with a laying head supporting plate which is in clearance fit with the inner wall of the hollow shaft. In the double-pipe spinning head invented in recent years, besides the middle spinning pipe supporting plate, a spinning pipe inlet part supporting sleeve is in clearance fit with the inner wall of the hollow shaft, and in two supporting positions in the hollow shaft, steel material iron oxide scale powder flying out from the joint part of the spinning pipe and the inlet guide pipe is embedded into the fit clearance in production and is tensioned after being baked and thermally expanded by the steel material in the spinning pipe at high temperature, so that the disassembly is difficult; in another particular case, the water-through cooling air seal of the front process equipment fails, and water enters the hollow shaft to generate scale in the matching clearance of the supporting disc, so that the laying head is difficult to remove.
The clearance between the hollow shaft of the laying head and the hollow shaft of the laying head body cannot be too large, and if the clearance is too large, the vibration value is easy to rise in a cold state; because the laying head mounting disc is not provided with the top threads for dismounting, the reason why the darnely technical personnel introduce that the top threads are not arranged is to prevent the matching end surface of the hollow shaft from being damaged by the top, so that the local combination of the end surface is not tight when the laying head is mounted, and the laying head is eccentrically arranged. The manufacturer gives a method of fully cooling before the laying head is disassembled, and then cooling. The field situation is that the time for changing the laying pipe is very tight, and the laying head cannot be cooled sufficiently for too long time. In addition, the risk of ejecting the laying head between the protective cover of the jack laying head and the laying head is that the force is not easy to control, and the axial positioning bearing of the laying head is easy to be damaged by too large force.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides a spinning head removing device. The device has simple structure and can quickly and easily replace the laying head.
The utility model provides a technical scheme that its technical problem adopted is: the device comprises a baffle plate, a baffle plate screw and a jackscrew; the baffle is provided with two screw holes which are in clearance fit with the baffle screws, and the center distance of the two screw holes is the same as that of the adjacent counterweight threaded holes on the spinning head; the diameter of the jackscrew is the same as that of a fixing bolt of a hollow shaft on the laying head body, and the length of the jackscrew is 40mm, 120mm longer than that of the fixing bolt; the thread parameters of the baffle plate screw are the same as the counterweight threaded hole of the laying head.
The utility model discloses simple structure can change the laying head fast easily.
Drawings
The present invention will be further explained with reference to the drawings and examples.
FIG. 1 is a front view of the present invention;
fig. 2 is a top view of the present invention;
FIG. 3 is a front view of the utility model in use;
fig. 4 is a sectional view of the utility model in use state a-a.
Detailed Description
As shown in fig. 1 and 2, the utility model comprises a baffle 2, a baffle screw 1 and a jackscrew 3; the baffle 2 is provided with two screw holes which are in clearance fit with the baffle screws 1, and the center distance of the two screw holes is the same as that of the adjacent counterweight threaded holes 7 on the spinning head 5; the diameter of the jackscrew 3 is the same as that of a fixing bolt 8 of a hollow shaft 6 on the laying head body, and the length of the jackscrew is 40mm, 120mm longer than that of the fixing bolt 8; the thread parameters of the baffle plate screw 1 are the same as the counterweight threaded hole 7 of the laying head 5.
And a support plate 4 is fixed on the end face of the baffle plate 2 close to the spinning head 5 so as to form a nut space of the jackscrew 3 and facilitate disassembly.
As shown in figures 3 and 4, when in use, the laying head 5 is hung by a hanging tool, eight fixing bolts 8 of the laying head are removed, and then two jackscrews 3 are screwed in the center symmetry. The baffle 2 is fixed above the jackscrews 3 through the counterweight threaded holes 7 on two sides, and the two jackscrews 3 are synchronously withdrawn by a wrench. Stopping after exiting for 40mm, adjusting the state of the lifting appliance, dismantling the jackscrew 3 and the baffle plate 2, and slowly moving out the spinning head.
