DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a blanking press, and particularly to a blanking press with improved coil support means.

When shearing a coil material into plate materials using a blanking press, it is widely and generally practiced to process a plurality of plate materials with one stroke of an upper mold in order to improve certain production efficiency.

However, as shown in the longitudinal cross-sectional view in Figure 1, for example,
Under the cooperation of the lower cutting blades 2 and 8 provided on the lower die 1 and the upper cutting blades 5 and 6 provided on the upper die 4, two sheets of plate material from the coil material 7 supplied from one direction are simultaneously cut. When shearing,
The portion of the coil material bridged by the blank chute 8 formed on the lower die 1 between the lower cutting blades 2 and 8 is a portion that protrudes forward from the lower cutting blade 8 in the forward direction of supply due to the deflection δ based on its own weight. length! As a result, the length L is longer than that of the coil material 7, which causes the length of the plate material to be uneven and waste of material. There is a risk that the coil material 7 may fail to pass over the blank chute 8 during supply, and this causes the problem that the tip of the coil material 7 comes into contact with the side wall of the blank chute 8, causing jamming there.

Therefore, as shown in a plan view in FIG. 2(a), a support plate 9 and a slide cam 10 are fixed to the side of the blank chute 8 perpendicular to the fill material supply direction so as to project somewhat into the blank chute. An operating plate 11 is provided which is attached and moves forward and backward into the blank chute (
A proposal has been made to support the bridging portion of the blank chute of the coil material 7 in both of these plays (see FIG. 2(b)) and 9.11.

According to this proposal, when the upper mold 4 is raised, the slide cam 10 projects the operating plate 11 into the blank chute under the force of a spring (not shown), so that the coil material 7 is smoothly supplied and the coil material 7 is smoothly supplied. Although there is an advantage that the deflection of the bridging part of the blank chute is effectively removed,
When shearing the coil material 7 into a plate material, the coil material 7 is first clamped by the holder 12 based on the lowering of the upper mold 4, and then the slide cam 10 is moved back by the drive cam 18 provided on the upper mold 4. The support of the coil material 7 by the operating plate 11 is released, and then the coil material 7 is sheared into a plate material under the cooperation of the lower cutting blades 2, 8 and the upper cutting blades 5, 6. In order to reciprocate the movement plate 11 over a sufficient horizontal distance within the limited vertical stroke of the slide cam 10, it is necessary to reduce the angle α of the cam surface 10a of the slide cam 10 with respect to the horizontal plane. If the reciprocating distance of the drive cam 18 is reduced until the required reciprocating distance of 11 is obtained, there is a problem that large noise and vibration will be generated when the drive cam 18 collides with the slide cam lO, and in order to increase the strength, the slide cam 10 and drive cam 13 had to be made larger.

Conversely, in order to solve this problem, if the angle α of the cam surface 10a is increased to increase the '1J-UO stroke of the upper mold 4, the crane 2 is normally not fixed to the slide 14. As shown in Figure (C), the urethane support member 1 for the upper die 4 supported against the lower die
Since the length of the urethane support part 5 has to be increased, there is a problem that the energy loss for elastically deforming the urethane support part 15 increases, and its durability decreases due to its own fatigue. In addition, +i& has the problem that the cycle time of the blanking press becomes long and processing efficiency decreases.

The present invention provides a blanking press that advantageously solves the problems of the prior art, and in particular, includes a support plate in which the coil material support means is provided at approximately the same level as the lower cutting blade, and this support plate. It consists of a horizontal cylinder that is always energized in the advancing direction, and a vertical cylinder that is equipped with a piston with a larger diameter than the piston of this horizontal cylinder and is located at a position where the upper mold is pressed when it descends. The coil material supporting means is characterized in that the horizontal cylinder and the vertical cylinder are connected so that when the vertical cylinder is pressed by descending, the horizontal cylinder is driven in a retreating direction, and this coil material supporting means has the following features:
At least one side of the blank chute partially or completely supports the coil material.

This coil material support means allows the ice general support plate to advance into the blank chute by the operation of a horizontal cylinder caused by the rise of the upper mold, thereby enabling effective support of the coil material, and by the lowering of the upper mold. Based on the operation of the vertical cylinder, fluid from the vertical cylinder operates a horizontal cylinder with a smaller diameter to move the horizontal support plate back by a greater amount than the lowering amount of the upper die, and the upper die has a relatively small lifting stroke. This provides a sufficient horizontal movement distance for the support plate.

The coil material support means 21 in this example has a lower blade 2.
A horizontal cylinder 2 is provided with a horizontal support plate 22 positioned at approximately the same level as the horizontal support plate 22, and the 7 rungs 22a of the horizontal support plate 22 are fixed to the blank chute bridging portion 1a of the lower mold 1.
The horizontal cylinder 2 is connected to the piston rod 28a of No. 8 and constantly biases the piston rod 23a in the direction, and is also fixed to the blank shaft bridge portion 1a.
The piston rod 25b of the vertical cylinder 25, which has a cylinder 25a larger in diameter than the cylinder bore of the horizontal cylinder 28, is made to protrude upward. It can be pressed down with a pressing protrusion 26 provided in the ring, and
The piston rod 23a is constructed by connecting a port 250 provided at the lower end of the cylinder 25a to a port 2J3d at the front end of the horizontal cylinder 28, thereby making it possible to control the movement of the piston rod 23a using the internal pressure of the cylinder 25a.

According to the coil material support means 21 configured in this manner, when the upper mold 4 is in the raised position and the pressing protrusion 26 is separated from the piston rod 25b as shown in FIG. % rearward distance of cylinder 28b from low pressure source 24
The main force supplied into the piston rod 23e
Since a has advanced, the horizontal support plate 22 is also traced out,
This makes it possible to support the coil material 7.

On the other hand, when the upper mold 4 gradually descends and the holder 12 securely clamps the coil material 7 at a predetermined position, the pressing protrusion 26 contacts the piston rod 25b and pushes it down, as shown in FIG. In this case, the internal pressure of the cylinder 25a is localized and transmitted to the front compartment 23f of the cylinder 28b, so that the piston rod 28a is moved to the rear compartment 23e.
Since the horizontal support plate 22 is also retreated against the internal pressure, the engagement between it and the fill material 7 is released. Then, the coil material 7 is successively sheared to become a plate material and is carried out from the blank chute 8.

Note that the retraction of the piston rod 23a and the horizontal support plate 22 here is sufficiently greater than the displacement of the rod 25b due to the difference in diameter between the cylinders 2.3b and 25a, so even if the vertical stroke of the upper mold 4 is small. , effective support of the coil material 7 by the horizontal support plate 22 may/will not cause any problems. Moreover, since the retreating speed of the horizontal support plate 22 here is faster than the descending speed of the rod 25b, the coil material 7 is moved 9'Jl! l
It is possible to reliably prevent the occurrence of deflection by supporting it until just before i.

Therefore, according to the present invention, the movement of the horizontal support plate is controlled by the large-diameter vertical cylinder operated by the upper mold and the small-diameter horizontal cylinder connected to the vertical cylinder, so that the upper mold can be moved in a small upward and downward stroke. can provide sufficient reciprocating distance to the water support plate under
The durability of the urethane support member for the upper mold is improved even in shearing molds in which the upper mold is not fixed to the slide in order to sufficiently prevent the generation of noise and vibration, etc.) and to shorten setup time. In addition to preventing a decrease in performance, it is also possible to shorten cycle time by reducing the length of the urethane support member.
