  • an up or down stroke of the dies 2 is determined by an eccentricity of the rotating axes 4, and as long as the center of rotation of the axes 4 is stationary, the thickness h of the slab 1 after being pressed is constant.
  • This apparatus is provided with dies 2 arranged at the upper and lower sides of the slab 1, sliders 8 that correspond to the respective dies and swing the dies up and down and backwards and forwards, and a driving system that drives the sliders, and the aforementioned sliders are composed of main slider units 8a with circular holes with center axes in the lateral direction of the slab, and cranks 9 provided with first axes 9a that engage with these circular holes and second axes 9b, whose diameters are smaller than those of the first axes and whose center axes are eccentric from the centers of the first axes, in which the second axes are driven and rotated by the above-mentioned driving system.
  • Fig. 3 shows an example using cranks and connecting rods; cranks 4 are connected to dies 2 equipped on the upper and lower parts of a slab 1 and the dies 2 press the slab when swinging up and down.
  • the up/down stroke of the dies 2 is determined by the eccentricity of the cranks 4, and as far as the rotating center of the cranks 4 is fixed, the thickness h of the slab after being pressed is constant.
  • the present invention has been achieved to solve the problem described above, and the object of the invention is to provide a dies gap adjustment apparatus for a plate thickness reduction press system, with which using the same dies, the thickness of a plate after being highly pressed can be easily adjusted.
  • the dies gap adjustment apparatus provided according to the present invention for a plate thickness reduction press system is provided with a pair of dies (2) equipped opposite each other on upper and lower sides of a slab (1) and a swing device (10) that moves the upper and lower dies symmetrically up and down with respect to the slab, via eccentric shafts or crank shafts, in which are provided upper and lower bearings (21, 22) that support the aforementioned eccentric shafts or crank shafts during rotation and a bearing moving device (24) that drives up and down at least one of the above-mentioned bearings.
  • the aforementioned bearing moving device (24) is composed of bearing boxes (25) supporting the bearings and screw jacks (27) that are installed on a main frame (26) and drive up and down the above-mentioned bearing boxes.
  • the gap of the dies can be adjusted by moving up and down the bearing boxes using screw jacks.
  • the aforementioned bearing moving device (24) can be configured with bearing boxes (25) that support the bearings and wedge plates (28) or step plates (29) that are sandwiched between and held by the main frame and the above-mentioned bearing boxes.
  • This configuration provides a simple, light structure in which the bearing boxes are moved up and down and the gap between the dies can be adjusted as well as reducing the cost.
  • Fig. 4 is a configuration of the plate thickness reduction press system equipped with the dies gap adjustment apparatus according to the present invention.
  • the plate thickness reduction press system equipped with the dies gap adjustment apparatus according to the present invention is provided with a pair of dies 2 arranged opposite each other on the upper and lower sides of the slab 1, and a swing device 10 that is provided for each of the upper and lower dies 2 and moves the die 2 backwards and forwards of the slab 1.
  • the swing device 10 is provided with a slider 12 equipped with a pair of circular holes 12a that are positioned obliquely to the feeding direction of the slab with a spacing L between each other, and eccentric shafts 14 that rotate inside the circular holes 12a.
  • the eccentric shaft 14 is composed of a first shaft 14a that rotates in the circular hole with the center axis A of the circular hole 12a, and a second shaft 14b that is driven and rotates with the center axis B displaced by an eccentricity e from the first axis 14a.
  • the second shaft 14b is supported by bearings, not illustrated, for rotation, and driven and rotated by a rotation driving device also not illustrated.
  • the dies 2 are mounted on the sliders 12, which are detachable through die holders 11.
  • pinch rolls 16 are provided and control a transfer speed of the slab 1 on the inlet or outlet side of the pinch rolls 16, a table roller 7 is equipped and transports a material to be pressed.
  • a and B represent the centers of the first and second shafts, respectively.
  • Fig. 5 is a view of general configuration of the dies gap adjustment device according to the present invention.
  • the dies gap adjustment apparatus 20 according to the present invention is equipped with upper and lower bearings 21, 22 that support rotation of the above-mentioned second shaft 14b, and a bearing moving device 24 that moves up and down at least one of these bearings.
  • the bearing moving device 24 is comprised of upper and lower bearing boxes 25 for supporting bearings 21, 22, and screw jacks 27 that move up and down a bearing box 25 installed on the main frame 26 of the plate thickness reduction press machine.
  • two upper screw jacks are provided, however, one screw jack or three or more screw jacks may also be incorporated.
  • the lower shaft box 25 is supported by a load cell 30 in Fig. 5, a dummy member can also support the box.
  • the shaft boxes 25 can be moved up and down and a gap between the dies can be adjusted by means of the screw jacks 27.
  • Figs. 6A and 6B show another embodiment of the dies gap adjustment apparatus according to the present invention.
  • Figs. 6A and 6B relate to a wedge-plate type and a step-plate type, respectively.
  • one wedge-shaped plate 28 or a plurality of them is inserted between and supported by the main frame 26 and the shaft box 25, and the wedge plate 28 is moved horizontally in this view, thus, the shaft box is moved up and down and a gap between the dies can be adjusted using a simple, light structure.
  • a step plate 29 whose thickness varies stepwise is inserted between and supported by the main frame 26 and the shaft box 25, and by moving the step plate 29 horizontally in this view, a gap between the dies can be adjusted while moving the shaft box up and down using the similar simple, light structure.
  • the construction of the dies gap adjustment apparatus according to the present invention is not limited to that of the plate thickness reduction press system shown in Fig. 4, but the pair of circular holes 12a of the slider 12 can also be positioned vertically to the feeding direction of a slab, therefore, the pair of eccentric shafts 14 can also be vertically located in the feeding direction of the slab.
  • any of the plate thickness reduction press systems shown in Figs. 1 through 3 can also apply.
  • the upper and lower bearings 21, 22 support the rotation of eccentric shafts or crank shafts other than the second shafts 14b in Fig. 4.
  • the present invention is also not limited only to the aforementioned embodiments, but can be modified within the range of the claims of the present invention.
  • the spacing between rotation centers of upper and lower eccentric shafts or crank shafts can be changed by moving up and down at least one of the upper and lower bearings 21, 22 that support rotation of the eccentric shafts or crank shafts, using the bearing moving device 24. Therefore, even when a pressing stroke of the upper and lower dies is constant and the same dies are used, the stroke range of each die varies, so that the thickness of a plate after being pressed can be adjusted freely. That is, by narrowing the space between rotation centers of the upper and lower eccentric shafts or crank shafts, the thickness of the plate after being highly pressed can be reduced, and conversely by widening the spacing between the rotation centers, the thickness of the sharply reduced plate can be made greater.
  • the dies gap adjustment apparatus of the present invention provides various advantages such as easy adjustment of the thickness of a plate after being highly pressed, using the same dies.
