Description

Technical Field

[0001] The utility model relates to the technical field of punching machines, in particular to a punching product discharging device. Background Art

[0002] In national production, stamping technology is more and more widely used because it saves materials and energy, is highly efficient, has low technical requirements for operators, and can produce products that cannot be achieved by mechanical processing through various mold applications. It is precisely because of the advantages of stamping that stamping processing is widely used, but at the same time, the safety issues it brings should not be underestimated. In processing, blanking is particularly important. In the past, the traditional method was to use the punch rod inside the mold to knock the workpiece out of the mold when the punch press mold was moved up, and then the workpiece was taken out manually, which led to safety accidents from time to time.

[0003] At present, the discharge of stamped products is mostly achieved by the setting of a robotic arm and a receiving box. However, the CNC robotic arms on the market are very expensive and the receiving boxes are mostly fixed in format. They cannot automatically discharge special stamping products (such as hardware stamping sheet products in new energy, medical and other industries), which affects the user experience.

[0004] The utility model proposes a solution to the above problems. Utility Model Content

[0009] In this embodiment, the conveying assembly also includes a suction mechanism for cooperating with the material box to fix the stamped product, the suction mechanism includes a vacuum suction head installed on the material box, an angle sensor for detecting the punching angle of the punch press, and a solenoid valve electrically connected to the angle sensor, when the angle sensor senses that the punching angle reaches a preset first angle, the solenoid valve controls the vacuum suction head to adsorb the stamped product, and when the angle sensor senses that the punching angle reaches a preset second angle, the solenoid valve controls the vacuum suction head to release the stamped product.

[0029] The terms "comprises," "comprising," or any other variations thereof, are intended to cover a non-exclusive inclusion of the elements listed and may also include additional elements not expressly listed.

[0030] like Figure 1 and Figure 5 As shown, it shows a stamping product discharging device provided in an embodiment of the utility model, including a transmission assembly and a conveying assembly; the transmission assembly includes at least one first connecting rod 1 and at least one second connecting rod 2, and the middle part of the first connecting rod 1 and the middle part of the second connecting rod 2 can be relatively pivotally assembled together; the conveying assembly includes a guide rail 8 and a material box 6 mounted on the guide rail 8, and the guide rail 8 is connected to one of the first connecting rod 1 and the second connecting rod 2; one end of the first connecting rod 1 is used to connect to the upper die of the punch press, and one end of the second connecting rod 2 is used to connect to the lower die of the punch press, so that the punch press drives the first connecting rod 1 and the second connecting rod 2 to pivot relative to each other during the opening and closing process, and then drives the guide rail 8 to drive the material box 6 to move to a preset material receiving position, so that the stamped product falls into the material box 6 when the punch press is opened.

[0031] Specifically, in this embodiment, the transmission assembly includes at least two first connecting rods 1 and at least two second connecting rods 2, the ends of each two adjacent first connecting rods 1 can be pivotally connected relative to each other, and the ends of each two adjacent second connecting rods 2 can be pivotally connected relative to each other; the transmission assembly also includes a bracket 5 installed on one side of the first connecting rod 1 close to the guide rail 8, and the bracket 5 is fixedly connected to the guide rail 8.

[0032] Specifically, in this embodiment, the transmission assembly also includes a third connecting rod 3 and a fourth connecting rod 4, one end of the third connecting rod 3 is relatively pivotally connected to the end of the first connecting rod 1 farthest from the upper die of the punch press; one end of the fourth connecting rod 4 is relatively pivotally connected to the end of the second connecting rod 2 farthest from the lower die of the punch press, and the other end is relatively pivotally connected to the other end of the third connecting rod 3.

[0033] The first link 1 and the second link 2 can pivot relative to each other through the hinge mechanism in the middle, the adjacent first link 1 can pivot relative to each other through the hinge mechanism at the end, the adjacent second link 2 can pivot relative to each other through the hinge mechanism at the end, one end of the third link 3 and the end of the first link 1 farthest from the upper die of the punch press can pivot relative to each other through the hinge mechanism, one end of the fourth link 4 and the end of the second link 2 farthest from the lower die of the punch press can pivot relative to each other through the hinge mechanism, and the other end of the third link 3 and the other end of the fourth link 4 are pivotally connected relative to each other through a hinge.

[0034] Specifically, in this embodiment, one end of the first connecting rod 1 is fixedly connected to the upper die of the punch press, one end of the second connecting rod 2 is fixedly connected to the lower die of the punch press, the first connecting rod 1 and the middle part of the second connecting rod 2 are connected by a hinge, the ends of two adjacent first connecting rods 1 are connected by a hinge, and the ends of two adjacent second connecting rods 2 are connected by a hinge. In the process of closing the upper and lower dies of the punch press, the angle between the first connecting rod 1 and the second connecting rod 2 changes from large to small, and the angle between adjacent connecting rods changes from small to large. The guide rail 8 fixedly connected to the first connecting rod 1 moves away from the punch press under the drive of the first connecting rod 1, and the material box 6 moves away from the punch press together with the guide rail 8, and the stamped product is transported to the discharge position.

[0035] like Figure 2 As shown, in this embodiment, the conveying component also includes a suction mechanism for cooperating with the material box 6 to fix the stamped product, the suction mechanism includes a vacuum suction head 9 installed on the material box 6, an angle sensor for detecting the punching angle of the punch press, and a solenoid valve electrically connected to the angle sensor. When the angle sensor senses that the punching angle reaches a preset first angle, the solenoid valve controls the vacuum suction head 9 to adsorb the stamped product. When the angle sensor senses that the punching angle reaches a preset second angle, the solenoid valve controls the vacuum suction head 9 to release the stamped product.

[0036] Specifically, in this embodiment, the angle sensor is installed on the punch press, and a plurality of vacuum suction heads 9 are provided, all of which are laid in the material box 6. The solenoid valve is electrically connected to the angle sensor to control the suction and closing of the vacuum suction head 9. An inclined surface is provided in the material box 6 to facilitate the output of the stamped products.

[0037] Specifically, in this embodiment, the conveying component also includes a contact sensor 10 installed on the material box 6 for sensing whether the stamped product is in contact with the material box 6. The material box 6 is also provided with an alarm device, which is electrically connected to the contact sensor 10 and can also be installed on the contact sensor 10 to prevent the stamped product from not entering the material box 6 and the contact sensor from sensing the product, thereby controlling the alarm device to sound an alarm and remind the staff.

[0038] Specifically, in this embodiment, the conveying assembly also includes a pulley mechanism 11 for reducing the friction between the stamped product and the material box 6. There are multiple pulley mechanisms 11, all of which are installed in the material box 6. After the vacuum suction head 9 is closed, the product increases the outward thrust under the action of the pulley mechanism 11 and the inclined surface of the material box 6, and the stamped product is sent out of the material box 6.

[0039] Specifically, in the present embodiment, one side of the material box 6 is a material outlet and is not provided with a baffle 7, while the other three sides are provided with baffles 7 to prevent the stamped products from falling during movement.

[0040] Specifically, in this embodiment, when the angle sensor senses that the punching angle reaches a preset first angle, the solenoid valve controls the vacuum suction head 9 to open, the material box 6 reaches the material receiving position, the vacuum suction head 9 adsorbs the stamped product, and the punching angle changes continuously. When it reaches the preset second angle, the material box 6 reaches the discharge position, the vacuum suction head 9 is closed, and the stamped product relies on its own weight and the inertia of the sudden stop of the material box 6 during movement to send the stamped product out of the material box 6.

[0041] like Figure 3 and Figure 4 As shown, in this embodiment, the stamping product discharging device also includes a material box 6 adjustment component, which includes a slider 13 fixedly connected to the material box 6 and an automatic locking pin mechanism 12 installed on the slider 13 for fixing the position of the slider 13. The slider 13 is movably installed on the guide rail 8. The material box 6 adjustment component can quickly and conveniently move the position of the material box 6 when repairing or cleaning the mold.

[0042] Specifically, in this embodiment, a slot 14 is provided on the guide rail 8, and the automatic locking pin mechanism 12 is movably installed in the slot 14. The material box 6 adjustment component also includes a magnet arranged in the slot 14 for adsorbing the automatic locking pin mechanism 12 to prevent the automatic locking pin mechanism from detaching from the slot 14.

[0043] Specifically, in the present embodiment, the automatic locking pin assembly is manually pushed, the automatic locking pin mechanism 12 is disengaged from the magnet and the card slot 14, and then the slider 13 is pushed to move on the guide rail 8, so that the material box 6 is disengaged from the previous position. When resetting, it is only necessary to pull the slider 13 to the card slot 14, and the automatic locking pin mechanism 12 is automatically stuck in the card slot 14. The magnet attracts the automatic locking pin to prevent the automatic locking pin mechanism 12 from being disengaged from the card slot 14 during movement.

[0044] The specific working process of the above-mentioned stamping product discharging device may include the following operations:

[0045] The punching machine starts and transmits the punching power to the transmission assembly, which drives the guide rail 8 and the material box 6 to move. The angle sensor senses the punching angle. When the preset first angle is reached, the material box 6 moves to the material receiving position, and the vacuum suction head 9 opens to cooperate with the material box 6 to carry the stamped product. The punching angle changes continuously, and the transmission assembly continues to drive the material box 6 to move to the preset discharge position. The vacuum suction head 9 is closed, and the stamped product is output to the outside of the material box 6 under the action of the inclined surface of the material box 6 and the pulley mechanism 11. The punching angle changes continuously from 0 to 360 degrees. The material box 6 circulates under the drive of the transmission mechanism to continuously output the stamped product.

[0046] The stamping product discharging device provided by the utility model can move the material box 6 to a preset material receiving position by relying on a transmission component, sense the punching angle of the punch press through an angle sensor, open the vacuum suction head 9 and cooperate with the material box 6 to adsorb the stamping product, and the transmission component continues to drive the material box 6 to move to the preset discharging position. The vacuum suction head 9 can fix the sheet-like special stamping product in the material box 6 during the movement from the material receiving position to the discharging position. When reaching the discharging position, due to the change in the punching angle, the vacuum suction head 9 releases the stamping product, and relies on the weight of the product plus the speed of the mechanism movement to throw the product out of the material box 6, thereby achieving the effect of automatic discharging.

[0047] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] In this document, the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, and may include other elements not explicitly listed in addition to those listed. The above description is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
