Abstract
Description
Technical Field
[0001] The utility model relates to a slitting machine, in particular to a side knife position lifting device for thin plate slitting. Background Art
[0002] When the existing thin plate slitting machine is used, the inlet center height and the shearing center height of the upper and lower blades of the disc shear must be consistent. However, after the disc knife has sheared a certain amount of work, the outer circle needs to be ground. In this way, the outer diameter of the blade will gradually become smaller due to the frequency of use, thereby causing the center height of the disc shear to become shorter. If the material is still fed at a fixed height, the thin plate will have creases and folds due to the height difference, affecting the quality of the slitting output strip. Summary of the Invention
[0003] The utility model provides a thin plate slitting side knife position lifting device which has a simple structure, can meet the requirements of feeding height adjustment to adapt to the shearing center of the disc shear, and ensure the slitting output quality.
[0004] Material toggling mechanism, its both sides respectively have a cylinder pressure, and the cylinder pressure bar connects swing arm, and the swing arm end face has hook portion, and a bar passes position between the end of two swing arms and the hook portion.
[0005] The outer side of the centering seat facing away from the slitting machine is also connected to an introduction bracket, and the introduction bracket supports an outer support plate which is not higher than the guide support roller.
[0006] The outer upper edge of the outer support plate is chamfered.
[0007] An inner support plate corresponding to the outer support plate is supported on the inner side of the outer force plate via a bracket.
[0008] The lifting cylinder is replaced by a lifting screw.
[0009] The beneficial effects of the present invention are as follows: the movable seat is driven by the movable adjusting screw to drive the centering seat to move, and the center of the thin plate is fed into the center of the centering seat through the outer vertical plates on the two centering blocks, and cooperates with the outer support plate and the inner support plate to play a role in feeding support and stability; the movable seat is driven by the lifting screw to correspond to the height center of the disc shear, and is pressed down by the guide downward pressure roller driven by the lifting cylinder, and cooperates with the guide support roller to ensure that the feeding height of the thin plate is accurately controlled and aligned with the height center of the disc shear, effectively avoiding product quality problems caused by height difference feeding.

DETAILED DESCRIPTION
[0013] The following is further explained with reference to the accompanying drawings.
[0014] Figure 1 、 2 Shown: A thin plate strip side knife position lifting device, including an adjusting bracket 3, a movable seat lifting screw 4, a movable seat 5, a movable adjustment handle 6, a movable adjustment screw 7, a movable block 8, a centering seat 9, a centering adjustment handle 10, an alignment adjustment screw 11, a centering block 12, an outer vertical plate 13, an inlet bracket 14, an outer support plate 15, an inner support plate 16, a guide support roller 17, a guide lower pressure roller 18, and a lower pressure roller lifting screw 19.
[0015] The adjusting bracket 3 is located in front of the entrance of the disc shear 2 of the slitting machine 1. The adjusting bracket 3 is supported by a movable seat lifting screw 4 to set a movable seat 5 along the central axis of the disc shear. The movable seat 5 is connected with a movable adjusting screw 7 with an external movable adjusting handle 6. The movable adjusting screw 7 is threadedly connected to a movable block 8. The movable block 8 supports and connects to a centering seat 9. The centering seat 9 is connected with a centering adjusting screw 11 with an external centering adjusting handle 10. Two centering blocks 12 are threadedly connected on both sides of the centering adjusting screw 11. The driven adjustment directions of the two centering blocks 12 on the centering adjusting screw are opposite or opposite, and an outer vertical plate 13 is vertically arranged on the centering block; a plurality of guide support rollers 17 are rotatably connected to the side of the movable seat 5 close to the slitting machine 1 along the axial direction of the movable adjusting screw, and a guide lower pressure roller 18 is also arranged in parallel above the center position between the two guide support rollers 17. The two ends of the guide lower pressure roller 18 are supported on the adjusting bracket 3 by two lower pressure roller lifting screws 19. An introduction bracket 14 is also connected to the outer side of the centering seat 9 facing away from the slitting machine. The introduction bracket 14 supports an outer support plate 1 that is not higher than the guide support roller. The outer upper edge of the outer support plate is chamfered, and the inner side of the external force plate is supported by an inner support plate 16 corresponding to the outer support plate through the bracket.
