Description

Technical Field

[0001] This utility model relates to the field of stamping equipment, and in particular to a reciprocating scrap removal mechanism for stamping dies. Background Technology

[0002] Stamping refers to the processing of raw materials using stamping dies and a punch press. The punch press provides the blanking force, driving the upper and lower dies to shear or deform the material. During sheet metal stamping, punching, trimming, and slitting processes generate a large amount of waste. Currently, waste is mostly cleaned manually with hand tools after accumulating to a certain level. This method is time-consuming and labor-intensive, greatly increasing the workload for workers. Furthermore, the act of removing waste involves a person reaching into the die with a hand tool while the punch press is running, posing certain safety hazards. To reduce the burden on workers and eliminate safety risks, it is essential to develop a waste removal device for stamping dies. Utility Model Content

[0003] To overcome the aforementioned shortcomings of existing manual methods for cleaning stamping waste, the technical problem to be solved by this utility model is to provide a reciprocating waste removal mechanism for stamping dies that can automatically remove waste.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A reciprocating scrap removal mechanism for stamping dies includes a motor, an eccentric disc, a transmission rod, a swing rod, and a scrap-dispelling plate. The eccentric disc is coaxially fixed on the motor shaft. One end of the transmission rod is rotatably connected to the eccentric shaft of the eccentric disc, and the other end is hinged to one end of the swing rod. The middle part of the swing rod is hinged to a support base, and the end away from the transmission rod is connected to one end of the scrap-dispelling plate. The scrap-dispelling plate is slidably disposed below the scrap removal section of the stamping die, and its end away from the swing rod is inclined downward. When the motor rotates, the eccentric disc causes the swing rod to reciprocate around the central hinge point through the transmission rod, thereby driving the scrap-dispelling plate to slide back and forth along the scrap removal direction.

[0006] Furthermore, the end of the swing rod away from the transmission rod is fixedly connected to the drive rod, and the axis of the drive rod is parallel to the axis of the hinge point in the middle of the swing rod; the end of the shaking plate near the swing rod is provided with an n-shaped clamping plate, which is slidably fitted on the drive rod, and the sliding direction is not parallel to the reciprocating motion direction of the shaking plate.

[0007] Furthermore, it also includes a support rod, the two ends of which are rotatably connected to a support base. The swing rod is fixed on the support rod and is hinged to the support base through the support rod. The active rod is fixedly connected to the support rod through multiple connecting plates.

[0008] Furthermore, the top of the support base is provided with a bearing seat, and both ends of the support rod are rotatably connected to the bearing seat.

[0009] Furthermore, the active rod is provided with a flange, one end of the connecting plate is fixedly connected to the active rod, and the other end is connected to the flange by screws.

[0010] Furthermore, the shaking plate comprises multiple plates, all of which are slidably mounted on the drive rod via an n-shaped clamp.

[0011] Furthermore, the motor is fixed to the frame of the stamping equipment via a base, with one support integrated with the base and the other support fixed to the frame of the stamping equipment.

[0012] Furthermore, the transmission rod includes two fisheye rods connected by a double-ended screw, and the two fisheye rods are respectively hinged to the eccentric shaft and the swing rod through a fisheye joint bearing.

[0013] Furthermore, the motor is a three-phase asynchronous variable frequency motor.

[0014] Furthermore, the material shaking plate has a groove-shaped structure, and the material shaking plate is slidably connected to the table surface of the stamping die through the support plate at the bottom. The two sides of the material shaking plate are slidably limited by the pads of the stamping die.

[0015] The beneficial effects of this utility model are as follows: By sliding a material shaker plate below the waste material outlet of the stamping die to receive the stamping waste, and using a reciprocating swing mechanism composed of a motor, eccentric disc, transmission rod and swing rod to drive the material shaker plate to make reciprocating linear motion, the waste material is sent from the material shaker plate to the waste box by inertia. This mechanism can effectively reduce the labor intensity of employees, avoid the safety risks of manually removing waste, and greatly improve the automation level of the factory and facilitate management.

Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings.

[0021] It should be noted that if this utility model contains directional indicators such as up, down, left, right, front, and back, these are used to describe the relative positional relationships between components and are not specific references to the absolute positions of related components or the positional relationships between components. They are only used to explain the relative positional relationships and movement of components in a specific posture. If the specific posture changes, the directional indicator will also change accordingly. If this utility model contains terms related to quantity, such as "many," "multiple," or "several," these specifically refer to two or more.

[0022] like Figure 1 , Figure 2 As shown, the present invention provides a reciprocating scrap removal mechanism for stamping dies, comprising a motor 1, an eccentric disk 2, a transmission rod 3, a swing rod 4, and a scrap shaking plate 5. The eccentric disk 2 is coaxially fixed on the rotating shaft of the motor 1. One end of the transmission rod 3 is rotatably connected to the eccentric shaft 21 of the eccentric disk 2, and the other end is hinged to one end of the swing rod 4. The middle part of the swing rod 4 is hinged to the support base 6, and the end away from the transmission rod 3 is connected to one end of the scrap shaking plate 5. The scrap shaking plate 5 is slidably disposed below the scrap removal part of the stamping die, and its end away from the swing rod 4 is inclined downward. When the motor 1 rotates, the eccentric disk 2 causes the swing rod 4 to reciprocate around the middle hinge point through the transmission rod 3, thereby driving the scrap shaking plate 5 to slide back and forth along the scrap removal direction. The eccentric disc 2, transmission rod 3, and swing rod 4 form a three-bar linkage mechanism, which converts the rotational motion of the motor 1 shaft into the back-and-forth swing of the swing rod 4. The transmission connection between the swing rod 4 and the shaking plate 5 converts the back-and-forth swing of the swing rod 4 into the forward and backward movement of the shaking plate 5. The shaking plate 5 is preferably a groove-shaped structure. The shaking plate 5 is slidably connected to the table surface of the stamping die through the bottom support plate 52, thereby controlling the tilt angle of the shaking plate 5. The two sides of the shaking plate 5 can be slidably limited by the pads of the stamping die.

[0023] The waste removal process of this utility model is as follows: the waste generated by stamping first falls onto the shaking plate 5, and then moves back and forth with the shaking plate 5. The characteristic of this reciprocating motion is that the velocity is zero at the zero point. Therefore, during the reciprocating motion, when the shaking plate 5 changes from a moving state to a stationary state, the waste on it will continue to move under the action of inertia. Furthermore, since the end of the shaking plate 5 away from the swing rod 4 is slightly tilted downwards, the tilt angle of the shaking plate 5 is not too large due to space limitations under the stamping die. However, this tilt angle is sufficient so that when the waste falls onto the shaking plate 5, regardless of whether the shaking plate 5 moves forward or backward, after a certain period of adjustment, the waste will eventually move towards the lower end of the shaking plate 5, thus shaking the waste out of the shaking plate 5 and collecting it in the waste box. Compared with the traditional manual waste removal method, this utility model can effectively reduce the labor intensity of employees, avoid the safety risks of manual waste removal, and can be directly modified based on existing stamping dies, which is convenient, quick, and has low modification costs.

[0024] Regarding the transmission connection between the swing rod 4 and the shaking plate 5, this utility model provides an embodiment. For example... Figure 1 , Figure 3 As shown, the end of the swing rod 4 furthest from the transmission rod 3 is fixedly connected to the drive rod 7, and the axis of the drive rod 7 is parallel to the axis of the hinge point in the middle of the swing rod 4. The end of the shaking plate 5 near the swing rod 4 is provided with an n-shaped clamping plate 51. The n-shaped clamping plate 51 is slidably fitted onto the drive rod 7, and the sliding direction is not parallel to the reciprocating motion direction of the shaking plate 5. The opening width of the n-shaped clamping plate 51 should be adapted to the outer diameter of the drive rod 7 to minimize the gap between them, so that the drive rod 7 can drive the n-shaped clamping plate 51 to move back and forth. The opening depth of the n-shaped clamping plate 51 should ensure that during the swing of the swing rod 4, the drive rod 7 will not drive the shaking plate 5 to move up and down, nor will it detach from the n-shaped clamping plate 51. This utility model uses an n-shaped clamping plate 51 to connect the drive rod 7 and the shaking plate 5, which improves the ease of installation of the shaking plate 5, and at the same time, converts the swing of the swing rod 4 into only the back-and-forth movement of the shaking plate 5, ensuring the smoothness of the reciprocating motion of the shaking plate 5.

[0025] Considering that a direct connection between the active rod 7 and the swing rod 4 might reduce structural strength, a further solution is to include a support rod 8. Both ends of the support rod 8 are rotatably connected to a support base 6. The swing rod 4 is fixed to the support rod 8 and hinged to the support base 6 via the support rod 8. The active rod 7 is fixedly connected to the support rod 8 via multiple connecting plates 81. This enhances the stability of the active rod 7 and the entire swing structure. Furthermore, multiple material-shaking plates 5 can be provided, all slidably mounted on the active rod 7 via n-shaped clamping plates 51. This allows for the provision of a material-shaking plate 5 for different scrap discharge points of the stamping die, and all material-shaking plates 5 can be moved using only one swing mechanism, further improving the scrap discharge effect. Additionally, to improve the smoothness of the movement of the support rod 8 and the active rod 7, a bearing seat 61 is provided at the top of the support base 6, and both ends of the support rod 8 are rotatably connected to the bearing seat 61. Regarding the installation method of the entire mechanism, the motor 1 can be fixed to the frame of the stamping equipment via the base 9, with one support 6 integrated with the base 9 and the other support 6 fixed to the frame of the stamping equipment.

[0026] Since this application mainly targets the modification of existing stamping equipment, the operating status of the entire mechanism may need to be adjusted according to the scrap discharge situation during the actual installation and use of the scrap discharge mechanism. Therefore, this application provides multiple adjustment points.

[0027] Firstly, a flange 82 is provided on the drive rod 7. One end of the connecting plate 81 is fixedly connected to the drive rod 7, and the other end is connected to the flange 82 by screws. The flange 82 has multiple screw holes. During the mechanism debugging stage, the installation position of the connecting plate 81 on the flange 82 can be adjusted according to the actual situation, thereby changing the position of the drive rod 7 so as to cooperate with the support plate 52, thereby adapting to or adjusting the position and tilt angle of the shaking plate 5, and thus adjusting the shaking plate 5 to a suitable movement state.

[0028] Then comes the length adjustment of transmission rod 3, such as... Figure 2 As shown, the transmission rod 3 includes two fisheye rods 32 connected by a double-ended screw 31. The two fisheye rods 32 are respectively hinged to the eccentric shaft 21 and the swing rod 4 via a fisheye spherical bearing 33. The connection of the two fisheye rods 32 via the double-ended screw 31 allows adjustment of the overall length of the transmission rod 3 during the mechanism debugging phase, thereby changing the swing amplitude and swing area of ​​the swing rod 4, and thus adjusting the operating state of the shaking plate 5. The fisheye spherical bearing 33 improves the rotational installation accuracy and ensures the smooth operation of the mechanism.

[0029] Finally, the speed of motor 1 is adjusted. Motor 1 can preferably be a three-phase asynchronous frequency converter motor, so that the reciprocating speed of the shaking plate 5 can be adjusted by adjusting the speed of motor 1, thereby adjusting the moving speed of the waste and optimizing the waste removal effect.

[0030] In summary, this invention uses a slidable material-shaking plate 5 below the waste material outlet of the stamping die to collect stamping waste. A reciprocating oscillating mechanism, composed of a motor 1, an eccentric disc 2, a transmission rod 3, and a swing rod 4, drives the material-shaking plate 5 in reciprocating linear motion, thereby using inertia to deliver the waste material from the material-shaking plate 5 to the waste material frame. This mechanism effectively reduces the labor intensity of employees, avoids the safety risks of manual waste removal, greatly improves the automation level of the factory, facilitates management, and has excellent practicality and application value.
