Definitions

  • the processing of wire rods is mostly made by rolling mills.
  • the rolling mill can be divided into a arch-type frame, a cantilever frame or a profile-welded frame-type frame according to its structure.
  • the adjustment and control of the roll spacing directly leads to the size of the product to be rolled, and the product to be rolled
  • the dimensional accuracy is dependent on the overall rigidity of the mill stand and rolls, the accuracy of the rolls and the material selection.
  • the vertical installation of the arch-type frame is taken as an example, and the deformation in the up-and-down direction is large and difficult to control because
  • the bearing housings are fixed to the bottom support of the arch-type frame by bolts.
  • the patent document entitled 'Roller Combination Rack' (Publication No. CN2796875Y) has a frame comprising upper and lower cross members 1, 4 and respective columns 2 connecting the two, and between the upper and lower beams 1, 4 and the column 2
  • the rod 8 and the nut 9 are connected such that the column 2 is subjected to compressive stress, and the structure has a drawback in that the positioning between the upper and lower beams 1, 4 and the column 2 in the direction perpendicular to the column 2 cannot satisfy the requirement because
  • the pressure provided between the upper and lower beams 1, 4 and the column 2, maintaining the position perpendicular to the column 2 depends on the friction between each other, which is extremely unreliable; in addition, due to the rod 8 and
  • the structure of the connection of the nut 9 is itself limited, and the pre-tightening force provided is very limited. Once the external force during the rolling process cancels the pre-tightening force provided by the rod 8 and the nut 9, it may lead to the upper and lower beams 1 in severe cases. 4
  • Figure 3 is a left side view of Figure 2;
  • the column 20 When assembling, the column 20 is stretched so that the step surface 21 and its lower end and the rolling stand 10 The length between the joints is appropriately stretched and deformed, and the column below the stepped surface 21 is in a stretched state and is pressed down by the stepped surface 21 onto the bearing block assembly 30.
  • the magnitude of the preload pressure is determined by Column 20
  • the amount of tensile deformation is determined.
  • the housing assembly 30 is only provided when the external force received by the chock assembly 30 is greater than the preload provided by the tensile deformation of the post 20. The beating will occur, and the present invention provides a suitable preloading force on the bearing block assembly 30 while the bearing block assembly 30 is reliably positioned under the support of the roll stand 10.
  • the lower portion 22c below the stepped surface 21 of the column 20 has mutually parallel faces 23
  • the face 23 is perpendicular to the axial direction of the roll
  • the lower section 22c is located in the groove body 11 of the upward direction of the rolling stand 10, and the spacing between the two parallel faces 23 and the groove body 11
  • the groove width is matched, and a hinge shaft 60 is disposed between the lower end of the lower portion 22c and the groove body 11, and the hinge shaft 60 is parallel to the axis of the roll.
  • the groove 31 is located at the front and rear sides of the seat body of the upper half of the bearing block assembly 30 and penetrates the upper and lower end faces of the upper half, the groove 31
  • the notch points in the front-rear direction and has a U-shaped cross section, and the groove walls of the groove 31 are parallel and the groove width and the step surface on the column 20 21
  • the following cylinders located in the grooves coincide in the axial direction of the rolls.
  • the step surface 25 faces the rolling mill in front of and behind the outer side of the workpiece to be rolled, and refers to the step surface 25 due to the column 20
  • the positions are different and different, that is, four columns 20 have two on the feed side of the rolls, and the other two columns 20 are located on the discharge side of the rolls; the step faces on the two columns 20 on the feed side of the rolls 25
  • the step surface 25 on the two columns 20 on the discharge side of the roll faces the rear-down direction of the discharge side of the roll
  • the direction of the head in Fig. 1 is the travel of the piece to be rolled. direction.
  • a cylinder 90 disposed between the second housing assembly 40 and the upper cross member 50 acts to push the second housing assembly downwardly.
  • the second bearing block assembly 40 is moved down and in contact with the first bearing block assembly 30 and transmits pressure to the rolling stand 10, at which time the upper cross member 50 and the rolling stand 10
  • the working pressure is such that the proper pre-tensioning deformation of the column 20 is obtained, thereby providing a suitable preloading force on the first bearing block assembly 30.
