Technical Field
[0001] The utility model belongs to the technical field of the lower support plate structure of blanking dies, and particularly relates to a buffer blanking lower support plate structure of a blanking die. Background Art
[0002] The lower support plate of a die generally refers to the component used to support the main structure of the die in the die. It is at the bottom of the die and plays the roles of stabilizing the die, bearing pressure, and positioning the die. In a blanking die, a blanking hole needs to be opened on the lower support plate to provide a passage for the workpiece to automatically fall from the die. When the workpiece falls into the receiving box, due to the lack of intermediate buffering, collisions and damages are likely to occur between the workpiece and the box body as well as between workpieces, resulting in economic losses. Summary of the Invention

[0005] Further, the receiving buffer member further includes an upper support and an elastic part. The upper support is arranged at the inlet end of the blanking hole, and the buffer receiving plate is elastically connected to the upper support through the elastic part, so that the buffer receiving plate is suspended in the blanking hole in a horizontal posture; the workpiece that has completed blanking falls on the buffer receiving plate and is buffered by the elastic force provided by the elastic part, and the buffer receiving plate descends out of the blanking hole due to the free-fall impact of the workpiece.
[0006] Further, the elastic part includes a large elastic part and a small elastic part respectively connected to both sides of the buffer receiving plate; a vibration driving part is installed on the buffer receiving plate; when the vibration driving part drives the buffer receiving plate to vibrate, the workpiece vibrates and displaces, and under the action of its own gravity, the side where the small elastic part of the buffer receiving plate is located descends to an inclined posture, and the workpiece slides along the plate surface of the buffer receiving plate in the inclined posture.
[0007] Further, the large elastic part is a thick elastic rope, and the small elastic part is a thin elastic rope. The buffer receiving plate without receiving materials is suspended in a substantially horizontal posture by the hoisting of the thick elastic rope and the thin elastic rope with the same length.
[0008] Furthermore, a vertical wall groove is provided on the inner hole wall of the blanking hole, and the elastic part is located in the wall groove.

[0014] The following further describes the utility model with reference to the accompanying drawings.
[0015] In a blanking die, a blanking hole needs to be opened on the lower support plate to provide a channel for the workpiece to automatically fall from the die. When the workpiece falls into the material receiving box, due to the lack of intermediate buffering, collisions are likely to occur between the workpiece and the box body and between the workpieces, resulting in collision damage and economic losses.
[0016] To solve the above problems, the technical solutions proposed by the present utility model are as Figure 1 、 Figure 2 and Figure 3As shown in the figure, a buffer blanking lower support plate structure of a blanking die includes a lower support plate 1 for supporting the lower die structure of the blanking die. A blanking hole 10 corresponding to the blanking cavity of the lower die structure is provided on the lower support plate 1. It is characterized in that: A material receiving buffer member 2 is correspondingly provided for the blanking hole 10. The material receiving buffer member 2 has a buffer receiving plate 5 that elastically enters and exits the blanking hole 10. The buffer receiving plate 5 includes a horizontal receiving posture and an inclined discharging posture that can be converted. Through the corresponding arrangement of the material receiving buffer member 2 for the blanking hole 10, the present invention buffers the blanking of the workpiece 9. Furthermore, the buffer receiving plate 5 for receiving materials serves as a relay consumption component for the kinetic energy of the workpiece 9, weakening the falling kinetic energy of the workpiece 9, thereby avoiding collision damage caused by excessive falling kinetic energy of the workpiece 9, ensuring the quality of the workpiece and economic benefits. In addition, the buffer receiving plate 5 can buffer the workpiece and convert it to an inclined posture, enabling the workpiece 2 on it to slide off, completing the final and safer blanking output of the workpiece.
[0017] As Figure 2 shown, the material receiving buffer member 2 further includes an upper support 3 and an elastic part 4. The upper support 3 is arranged at the inlet end of the blanking hole 10. A mounting member 7 is movably connected to the upper support 3. An installation groove 101 corresponding to the upper support 3 is opened at the inlet end of the blanking hole 10. The upper support 3 is embedded and installed in the installation groove 101 through the mounting member 7 to avoid causing a safety obstacle to the lower die structure of the blanking die. The mounting member 7 is preferably an internal hexagonal bolt. The buffer receiving plate 5 is elastically connected to the upper support 3 through the elastic part 4, so that the buffer receiving plate 5 is suspended horizontally in the blanking hole 10. The completed blanking workpiece 9 falls on the buffer receiving plate 5 and realizes buffering through the elastic force provided by the elastic part 4. And the buffer receiving plate 5 descends out of the blanking hole 10 due to the free-fall impact of the workpiece 9. When the workpiece 9 impacts on the buffer receiving plate 5, based on the elastic force of the elastic part 4, the buffer receiving plate 5 elastically descends to buffer the workpiece 9 until the buffer receiving plate 5 exits the blanking hole 10.
[0018] More specifically, as Figure 2 and Figure 3As shown, the elastic part 4 includes a large elastic part 41 and a small elastic part 42 respectively connected to both sides of the buffer material receiving plate 5; in the present utility model, preferably, the large elastic part 41 is a thick elastic rope, and the small elastic part 42 is a thin elastic rope. The buffer material receiving plate 5 without material is in a substantially horizontal posture by being hoisted by the thick elastic rope and the thin elastic rope with the same length. A vibration driving part 6 is installed on the buffer material receiving plate 5; when the vibration driving part 6 drives the buffer material receiving plate 5 to vibrate, the workpiece 9 vibrates and displaces, and under the action of its gravity, the side of the buffer material receiving plate 5 where the small elastic part 42 is located descends to an inclined posture, and the workpiece 9 slides along the plate surface of the buffer material receiving plate 5 in the inclined posture. The vibration driving part 6 is preferably a vibrator. After the vibrator is started, since the elastic force of the small elastic part 42 is less than that of the large elastic part 41, under the vibration action, the buffer material receiving plate 5 carrying the workpiece 9 will tilt slightly on the side where the small elastic part 42 is located. Then, due to the vibration and the gravity of the workpiece 9, the workpiece 9 will displace towards the side where the small elastic part 42 is located while vibrating, that is, vibrate and displace, thereby gradually increasing the inclination angle of the buffer material receiving plate 5 until the workpiece 9 slides off the buffer material receiving plate 5.
[0019] In order to provide a accommodation space for the elastic part 4, as Figure 1 shown, a vertical wall groove 100 is provided on the inner hole wall of the blanking hole 10, and the elastic part 4 is located in the wall groove 100.
[0020] The lower support plate 1 is further provided with a spring hole 11, a screw through hole 12 and a threaded blind hole 13; among them: the diameter of the spring hole 11 is 32.0 mm, and the positive sinking depth is 15.0 mm; the diameter of the screw through hole 12 is 11.0 mm and needs to be drilled through; the specification of the threaded blind hole 13 is M20×P2.5, and the positive tapping depth is 40.0 mm.
[0021] The above are only the preferred embodiments of the present utility model. It should be noted that: for those of ordinary skill in the art of this technology, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
