Abstract
The utility model discloses a thrust brake of a Sendzimir mill. The thrust brake comprises supporting columns and a clamping groove. The thrust brake is characterized in that the clamping groove is E-shaped, and the supporting columns are placed in two groove bodies of the clamping groove respectively. The thrust brake reduces abnormal twisting damage to the surfaces of the thrust brake supporting columns, reduces cost and shortens equipment fault time.
Description
Technical field
The utility model relates to a kind of sendzimir mill thrust brake, belongs to mechanical field.
Background technology
Sendzimir mill is in the operation of rolling, and for preventing the working roll axial float, in milling train transmission side and each design of fore side a thrust brake, purpose being arranged is axial float when preventing that working roll is rolling.As shown in Figure 1.
In the operation of rolling, the linear velocity of upper and lower working roll is the same, i.e. ν

Down, cause upper working rolls and lower working rolls angular speed difference, i.e. ω
On≠ ω
DownLike this, the upper working rolls and lower working rolls end is different with the rotating speed that the place of thrust brake contact produces, and it is bad serious to cause the thrust brake surface to rub with the hands.
Summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of sendzimir mill thrust brake, the thrust brake of upper working rolls and lower working rolls is separated, can effectively avoid because the different bad serious phenomenons of thrust brake surface stranding that cause of the rotating speed that the place of upper and lower working roll end and thrust brake contact produces.
The technical solution adopted in the utility model is: a kind of sendzimir mill thrust brake, comprise support column, and draw-in groove is characterized in that: described draw-in groove is E shape, two grooves of draw-in groove are placed support column respectively.
In the such scheme, the thickness of the middle part gripper shoe of described draw-in groove is 1/3rd of top working roll or bottom working roll diameter.
The thrust brake that the utility model provides, compared with prior art, the support column shape diminishes, and quantity increases, and draw-in groove becomes E shape groove by Baltimore groove, and the last low groove of E shape groove can be installed support column respectively.
The sendzimir mill thrust brake that the utility model provides, the beneficial effect that brings: it is bad that (1) reduces the improper stranding in surface of thrust support column, reduced cost; (2) reduced the equipment fault time.
Below in conjunction with drawings and Examples the utility model is described further.
Description of drawings
Fig. 1 is the structural representation of existing sendzimir mill thrust brake.
Fig. 2 is structural representation of the present utility model.
1 is top working roll among the figure, and 2 is bottom working roll, and 3,4 is support column, and 5,6 is the spill draw-in groove, and 7,8,9,10 is support column, and 11,12 is E shape draw-in groove.
The specific embodiment
Embodiment:
As shown in Figure 1, the sendzimir mill thrust brake that uses in the prior art, comprise support column 3,4 and spill draw-in groove 5,6, top working roll 1, bottom working roll 2 two ends contact support column 3,4 respectively, top working roll 1, bottom working roll 2 since the difference of angular speed can to cause support column 3,4 surfaces to rub bad phenomenons with the hands serious.
Fig. 2 shows structural representation of the present utility model, the sendzimir mill thrust brake, comprise support column 7,8,9,10 and E shape draw-in groove 11,12,1 liang of end in contact support column 7 of top working roll, 9,2 liang of end in contact support columns 8 of bottom working roll, 10, E shape draw-in groove 11 is placed support column 7,8, and E shape draw-in groove 12 is placed support column 9,10.
Used this device on the Taiyuan Iron and Steel Co. cold rolling mill 11# sendzimir mill, the diameter of upper and lower working roll is 63.5mm, and the Thickness Design of middle part gripper shoe is 21mm when making E shape draw-in groove.At milling train fore side and transmission side this E font thrust brake has been installed, effect is very obvious, and it is bad not only to reduce the support column improper stranding in surface, has also reduced the equipment fault time.
Claims (2)
1. a sendzimir mill thrust brake comprises support column, and draw-in groove is characterized in that: described draw-in groove is E shape, and two grooves of draw-in groove are placed support column respectively.
