Abstract
The utility model discloses a drawing die for a bearing of a straightening machine, which comprises a blocking and connecting mechanism. The blocking and connecting mechanism can be used for blocking a bearing shaft sleeve and is connected with a press plate through a connecting rod. When the drawing die for the bearing of the straightening machine is used, firstly, a shaft of the bearing of the straightening roller on the straightening machine is sleeved through the blocking and connecting mechanism; and then, a hydraulic jack is crammed between the shaft of the straightening roller and the press plate of the drawing die for the bearing of the straightening machine; two ends of the hydraulic jack respectively pushe against the press plate and the shaft of the straightening roller; the hydraulic jack is used for exerting certain pressure so that the bearing can be returned from the shaft of the straightening roller to dismount in a very successful way. The drawing die for the bearing of the straightening machine can be used for dismounting the bearing from the shaft of the straightening roller in a very convenient way, without damaging the bearing; the bearing can be further continuously used; therefore, with the adoption of the drawing die for the bearing of the straightening machine, the working efficiency can be improved, furthermore the production cost can be effectively reduced.
Description
Technical field
The utility model relates to a kind of bearing extractor, particularly a kind of drawing-die that is used for the dismounting of straightener upper bearing (metal).
Background technology
Straightener is the equipment that shape, bar, tubing, wire rod etc. are aligned, and it pushes the aligning of realizing bar through smoothing roll to bar etc.The AF3K bearing is the bearing of certain straightener roll of straightener, and this bearing is by external import, and each bearing unit price is about 10,000 yuan.Because the requirement of production precision has 6 smoothing rolls on this straightener, each smoothing roll needs transposing in 3 months once to safeguard, to guarantee its machining accuracy.Because AF3K bearing and smoothing roll are fixed through interference fit; And the interval between installation site and the smoothing roll is very little; Therefore the drawing-die that generally is used to dismantle bearing can't be used, thus can only be with taking off after the bearing cutting when changing bearing at every turn, and the bearing after the cutting can't reuse; Will cause very big cost waste to production like this, make production cost improve.
The utility model content
To the deficiency of above-mentioned prior art, the technical problem that the utility model will solve provides a kind of simple in structure and can need not to destroy the drawing-die that bearing just can take out bearing.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of straightener bearing drawing-die, it comprises a clamping mechanism that can be used for blocking the bearing axle sleeve, said clamping mechanism is connected with a pressing plate through connecting rod.
Preferably, said clamping mechanism is made up of two semicircle clips, connects through bolt between said two semicircle clips.
Preferably, said clamping mechanism is connected with said pressing plate through two connecting rods, and said two connecting rods are fixedly connected with a semicircle clip of said clamping mechanism.
Technique scheme has following beneficial effect: this straightener bearing drawing-die in use; At first put through the bearing shaft of clamping mechanism with the straightener upper straightening roll; Between the axle of smoothing roll and the pressing plate of straightener bearing drawing-die, fill in a hydraulic jack then; Make the two ends of hydraulic jack withstand the axle of pressing plate and smoothing roll respectively, apply certain pressure through hydraulic jack then, pressure passes to the axle sleeve on the bearing through pressing plate, connecting rod, clamping mechanism; As long as applied pressure enough can withdraw from the axle of bearing from smoothing roll greatly, thereby accomplish the dismounting of bearing.Use this straightener bearing drawing-die very easily the axle of bearing from smoothing roll to be disassembled; And can not cause any destruction to bearing; Bearing still can continue to use, and therefore uses this straightener bearing drawing-die not only can increase work efficiency, and can effectively reduce production costs.
Above-mentioned explanation only is the general introduction of the utility model technical scheme, in order more to know the technological means of understanding the utility model, and can implement according to the content of specification, below with the preferred embodiment of the utility model and conjunction with figs. specify as after.The specific embodiment of the utility model is provided by following examples and accompanying drawing thereof in detail.
Description of drawings
Fig. 1 is the vertical view of the utility model embodiment.
Fig. 2 is the front view of the utility model embodiment.
Fig. 3 is the structural representation of the utility model embodiment user mode.
The specific embodiment
Describe in detail below in conjunction with the preferred embodiment of accompanying drawing to the utility model.
Like Fig. 1, shown in 2, this straightener bearing drawing-die comprises a clamping mechanism that can be used for blocking the bearing axle sleeve, and this clamping mechanism is made up of two semicircle clips 1, connects through bolt 4 between two semicircle clips 1.Clamping mechanism is connected with a pressing plate 3 through two connecting rods 2, and one in two each and every one the semicircle clips 1 of two connecting rods 2 and clamping mechanism is fixedly connected.
This straightener bearing drawing-die at first is stuck in two semicircle clips 1 on the axle sleeve 8 of smoothing roll 5 upper bearing (metal)s 7, and through bolt 4 semicircle clip 1 is coupled together in use.Between the axle 6 of smoothing roll and the pressing plate 3 of straightener bearing drawing-die, fill in a hydraulic jack 9 then; Make the two ends of hydraulic jack 9 withstand the axle 6 of pressing plate 3 and smoothing roll respectively; Apply certain pressure through hydraulic jack 9 then; Pressure passes to the axle sleeve 8 on the bearing through pressing plate 3, connecting rod 2, clamping mechanism, as long as applied pressure enough can withdraw from the axle 6 of bearing 7 from smoothing roll greatly, thus the dismounting of completion bearing.
Use this straightener bearing drawing-die very easily the axle of bearing from smoothing roll to be disassembled; And can not cause any destruction to bearing; Bearing still can continue to use, and therefore uses this straightener bearing drawing-die not only can increase work efficiency, and can effectively reduce production costs.
More than a kind of straightener bearing drawing-die that the utility model embodiment is provided carried out detailed introduction; For one of ordinary skill in the art; According to the thought of the utility model embodiment, the part that on the specific embodiment and range of application, all can change, in sum; This description should not be construed as the restriction to the utility model, and all any changes of being made according to the utility model design philosophy are all within the protection domain of the utility model.
