Summary of the invention
Technical problem to be solved in the utility model provides a kind of cold rolling cutter knife rest copper sheathing dismounting chest expander, utilize this chest expander can make things convenient for the dismounting of cutter knife rest copper sheathing, guarantee copper sheathing stressed even and unlikely damage in unloading process, improved the efficient of copper sheathing field-strip simultaneously.
For solving the problems of the technologies described above, the cold rolling cutter knife rest of the utility model copper sheathing dismounting chest expander, comprise cutter body and copper sheathing, described copper sheathing is positioned at the axis hole of described body, and this chest expander comprises location-plate, gland seat, gland, screw rod, hydraulic jack and two nuts;
Described location-plate is positioned at a side of described copper sheathing, described location-plate center has first through hole, its end face towards described copper sheathing is provided with first positioning step, the diameter of described first positioning step and the internal diameter of described copper sheathing coupling, and the diameter of described location-plate is less than the external diameter of described copper sheathing;
Described gland seat is cylindrical shape and the diameter external diameter greater than described copper sheathing, its end face is positioned at the opposite side of described copper sheathing, described gland center has second through hole and is positioned at the other end of described gland seat, described gland is provided with second positioning step towards the end face of gland seat, the internal diameter coupling of the diameter of described second positioning step and described gland seat, the diameter of described gland is consistent with the external diameter of described gland seat;
Described hydraulic jack is positioned at the described gland outside, and described screw rod passes hydraulic jack center, first through hole and second through hole and is positioned at location-plate, gland seat, gland and hydraulic jack center, and described two nuts are twisted respectively in described screw rod two ends.
Further, for ease of observing the dismounting situation of copper sheathing, have peep hole on the seat wall of above-mentioned gland seat near described copper sheathing during the work of this chest expander.
Because the cold rolling cutter knife rest of the utility model copper sheathing dismounting chest expander has adopted technique scheme, promptly make location-plate, gland seat, gland and screw rod respectively, location-plate is provided with the side that positioning step is located at copper sheathing, the gland seat is positioned at the opposite side of copper sheathing, gland is provided with the opposite side that positioning step is positioned at the gland seat, hydraulic jack is positioned at the outside of gland, and location-plate, gland seat, gland and hydraulic jack center penetrate screw rod, the screw rod two ends nut of screwing on respectively; Utilize this chest expander can make things convenient for the dismounting of cutter knife rest copper sheathing, guarantee copper sheathing stressed even and unlikely damage in unloading process, improved the efficient of copper sheathing field-strip simultaneously.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and embodiments:
Fig. 1 is the structural representation of the cold rolling cutter knife rest of the utility model copper sheathing dismounting chest expander.
The specific embodiment
As shown in Figure 1, the cold rolling cutter knife rest of the utility model copper sheathing dismounting chest expander, comprise cutter body 1 and copper sheathing 2, described copper sheathing 2 is positioned at the axis hole of described body 1, and this chest expander comprises location-plate 3, gland seat 4, gland 5, screw rod 7, hydraulic jack 6 and two nuts 8;
