Abstract
Description
- The present invention relates to a dies gap adjustment apparatus for a plate thickness press system, which can greatly reduce the thickness of the plate through one pass.
- As a means of one-pass, high-reduction pressing, press systems with conventional stentering press machines modified to a plate-thickness pressing system have been proposed (for example, Japanese patent publication No. 014139, 1990, unexamined Japanese patent publications No. 222651, 1986, No. 175011, 1990, etc.).
- According to the unexamined Japanese patent publication No. 175011, 1990 "Flying Sizing Press Apparatus" as shown in Fig. 1, for instance, rotating
axes 4 are provided at the upper and lower or left and right sides of a line Z for transferring the material to be formed, and boss portions of connectingrods 3 with a required shape are engaged with eccentric portions of the rotatingaxes 4, and, in addition,dies 2 are connected to the tip portions of the connectingrods 3 in opposition to the line Z for transferring the material to be formed, in which the thickness of thematerial 1 to be formed (slab) is reduced by rotating theaxes 4 and pressing the upper and lower surfaces of the material by means of thedies 2 via the connectingrods 3 coupled with the eccentric portions of the rotating axes. At that time, an up or down stroke of thedies 2 is determined by an eccentricity of therotating axes 4, and as long as the center of rotation of theaxes 4 is stationary, the thickness h of theslab 1 after being pressed is constant. - It is also proposed to use the press as shown typically in Fig. 2, for the same purpose. This apparatus is provided with
dies 2 arranged at the upper and lower sides of theslab 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 ofmain slider units 8a with circular holes with center axes in the lateral direction of the slab, andcranks 9 provided withfirst axes 9a that engage with these circular holes andsecond 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. - In this configuration, when the
second axes 9b rotate, thefirst axes 9a carry out a crank motion with the centers of the second axes, and give themain slider units 8a up, down, backward, and forward motions through the circular holes in engagement. In this way, the sliders 8 press the dies and can give the dies a forward motion during a pressing period, therefore, theslab 1 is driven forwards (in the direction of flow of the slab) while being pressed, so the pressing operation is activated continuously. In addition, because thedies 2 press theslab 1 from both upper and lower sides of the slab, a large reduction can be achieved. In Fig. 2, 6 and 7 represent pinch rolls and transfer tables, respectively. - Fig. 3 shows an example using cranks and connecting rods;
cranks 4 are connected todies 2 equipped on the upper and lower parts of aslab 1 and thedies 2 press the slab when swinging up and down. In this case, too, the up/down stroke of thedies 2 is determined by the eccentricity of thecranks 4, and as far as the rotating center of thecranks 4 is fixed, the thickness h of the slab after being pressed is constant. - Furthermore, various means to sharply reduce thickness have been proposed for plate thickness reduction press apparatus that can greatly reduce work through one pass, by the inventors of the present invention, etc.
- As described above, however, with a plate thickness reduction press apparatus that can greatly reduce work through one pass, cams or cranks are used to drive upper and lower dies upwards and downwards, therefore, the pressing stroke of the upper and lower dies remains constant at all times. Accordingly, one of the problems with such an apparatus was that the thickness of a plate after being pressed is constant as long as the same dies are used, so the thickness of the plate after a sharp reduction is difficult to adjust.
- 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.
- Using this configuration, it is possible to change the spacing between rotation centers of the upper and lower eccentric shafts or crank shafts by moving up and down at least one of the upper and lower bearings (21, 22) that support the eccentric shafts or crank shafts during rotation, using the bearing moving device (24). Consequently, even when pressing strokes of the upper and lower dies are constant and the same dies are used, the thickness of a plate after being pressed can be adjusted freely because each stroke range varies. In other words, the thickness of the plate after being highly pressed can be made smaller by narrowing the spacing between rotation centers of the upper and lower eccentric shafts or crank shafts, and it can also be made thicker after a sharp reduction conversely by widening the spacing between the rotation centers.
- According to a preferred embodiment of the present invention, 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. In this configuration, the gap of the dies can be adjusted by moving up and down the bearing boxes using screw jacks.
- In addition, 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.
