Description

Technical Field

[0001] The utility model relates to the technical field of punching machines, in particular to a quick material feeding mechanism for a punching machine. Background Art

[0002] Dovetail pads are one of the indispensable components in electrical equipment such as transformers. They are used for horizontal oil and air passages between turns or sections of coils. They are also a supporting surface to withstand the axial force of the coils. When processing large quantities of dovetail pads, a punching machine is required. The cardboard is transported to the punching end of the punching machine for punching through a feeding mechanism, a conveying mechanism and other devices. After punching, the cardboard falls into a storage box through a feeding chute at the feeding port. The inventor previously designed a punching machine, such as patent number CN117531928A, which discloses a fully automatic punching machine. The punched dovetail pads fall at the slide plate 201, but in actual use, the punching speed of the punching machine is relatively fast, and more dovetail pads are easily accumulated on the slide plate. Due to the slope of the slide plate and the weight of the dovetail pads, the sliding speed is slow, which affects the discharge speed, and when falling into the storage box, the falling points are relatively concentrated, and it is easy to accumulate in a pointed shape, requiring staff to frequently manually sort out the accumulated dovetail pads. Utility Model Content

[0003] In order to solve the technical problems existing in the above-mentioned background technology, the utility model provides a rapid material unloading mechanism for a punching machine.

[0004] The technical solution of this utility model is as follows:

[0005] A quick unloading mechanism for a punching machine, the unloading mechanism is arranged at one side of the discharge port of the punching machine, and comprises an unloading platform, a unloading trough is hinged on the unloading platform, and the hinge point of the unloading trough is arranged close to the outer side of the unloading platform;

[0006] One end of the feed chute is arranged close to the discharge port of the punching bed, and the other end is inclined downward and extends to the outside of the discharge platform;

[0007] A driving mechanism is arranged in the discharge platform, and the output end of the driving mechanism is arranged in contact with the bottom of one end of the discharge chute close to the discharge port, which can drive the discharge chute to rotate around the hinge point, and a support column for supporting the discharge chute is arranged on the discharge platform close to the discharge port.

[0008] In order to reduce the output pressure of the driving mechanism and prevent the chute from moving up and down at too large an angle, thereby causing the dovetail pad to fly out of the chute, the hinge point of the chute is longer from one end of the chute close to the driving mechanism than from the other end.

[0009] In order to ensure that the dovetail pad punched by the punching bed can fall into the discharge chute, the maximum height that can be reached by one end of the discharge chute close to the discharge port is not higher than the discharge port.

[0010] The specific design of the driving mechanism is that the discharging mechanism includes a driving motor installed in the discharging platform, the driving motor is connected to a cam, and the cam drives the hinge point of the discharge chute sleeve to rotate through the connecting structure.

[0012] In order to prevent the push plate from contacting the part of the cam close to its rotating shaft when it is at the lowest point, a spring is sleeved on the outer side of the slide column, and one end of the spring is connected to the limit block, and the other end is connected to the push plate, and the lowest point that the push plate can reach is set to be non-contact with the cam. When the cam rotates from the protruding position to close to the push plate, it can generate an instantaneous thrust on the push plate, and then generate an instantaneous upward thrust on the material discharge chute, continue to rotate, the material discharge chute falls, reciprocating, forming a vibration effect on the material discharge chute, and increasing the material discharge speed.

[0013] In order to reduce the impact of the sliding column on the material discharge chute when it moves up and down, a buffer pad is arranged at the bottom of the material discharge chute, and a contact plate is installed on the lower side of the buffer pad, and the contact plate is arranged in contact with the upper end of the sliding column.

[0014] In order to better support the blanking and reduce wear, the upper end of the sliding column is set to a spherical surface, and the side of the contact plate that contacts the sliding column is set to an arc shape.

[0015] In order to facilitate the replacement of the push plate, a threaded column is provided on the upper end of the push plate and is installed with the bottom end of the sliding column through a thread.

[0016] In order to prevent the dovetail pad from flying out of the material discharge chute, a plurality of material blocking plates are arranged at intervals at the upper end of the material discharge chute.

[0017] The beneficial effects of the utility model are as follows: the utility model is a fast unloading mechanism for a stamping machine.

[0026] Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings.

[0027] Example

[0028] As mentioned in the background technology, a punching machine 1 is used when processing dovetail pads. The punching machine 1 designed by the inventor previously has certain defects when unloading materials. Since the discharge speed of the punching machine 1 is relatively fast, the dovetail pads that fall onto the slide plate at the discharge port 11 are prone to accumulation, affecting the unloading speed. In addition, the discharge position on the slide plate is too concentrated, which is easy to pile up in the storage box. The staff needs to frequently organize the storage box, which requires too much manpower. Therefore, the inventor has improved on the existing technology and designed a new unloading mechanism, which is described in detail below with reference to the drawings.

[0029] This embodiment provides a rapid material unloading mechanism for a punching machine. Figure 1 The unloading mechanism is arranged on one side of the discharge port 11 of the punching bed 1, that is, on the side away from the loading mechanism, and includes a discharge table 2, on which a unloading chute 3 is hinged, and the hinge point of the unloading chute 3 is arranged close to the outer side of the discharge table 2, that is, the hinge point is located at the edge of the discharge table 2, and the unloading chute 3 is arranged non-contacting with the edge of the discharge table 2 during the activity. Only when the end of the unloading chute 3 close to the discharge port 11 rotates to the uppermost end, the bottom of the discharge table 2 limits the unloading chute 3. Support plates are arranged on both sides of the unloading chute 3, and the unloading chute 3 is rotatably connected to the support plates through two rotating shafts.

[0030] Specifically, one end of the feed chute 3 is arranged close to the discharge port 11 of the punching bed 1, and the other end is inclined downward and extends to the outside of the discharge platform 2, and a storage box is placed on the outer reference plane to receive the dovetail pads that slide down from the feed chute 3, that is, the feed chute 3 is inclined downward from one end close to the discharge port 11 to the other end, to ensure that the dovetail pads coming out of the discharge port 11 can slide down by their own weight.

[0031] One of the contribution points that is different from the prior art is that a driving mechanism 4 is arranged in the discharge platform 2, and the output end of the driving mechanism 4 is arranged in contact with the bottom of one end of the discharge chute 3 close to the discharge port 11, which can push the discharge chute 3 to rotate around the hinge point. When the discharge chute 3 rotates around the hinge point, the end away from the discharge port 11 swings up and down, thereby accelerating the discharge speed of the dovetail pad in the discharge chute 3.

[0032] Specifically, the driving mechanism 4 includes a driving motor 41 installed in the discharge platform 2, and the driving motor 41 is connected to a cam 42. The cam 42 drives the chute 3 to rotate around the hinge point through a connecting structure, and a support column 5 is provided on the discharge platform 2 near the discharge port 11, which is located below the chute 3 and has two sections arranged along the width direction of the discharge platform 2, which can support one end of the chute 3 near the discharge port 11, and at this time, the chute 3 is still in a downwardly inclined state, and through the rotation of the cam 42, relying on its contour, one end of the chute 3 can be lifted up at its protruding position, and continue to rotate after being lifted up, and the end of the chute 3 near the discharge port 11 has more dovetail pads, and the chute 3 can fall freely due to its own weight and the weight of the dovetail pads, and fall on the support column 5, and at the cam 42 When it rotates to the protruding position, it continues to push up the material discharge chute 3, realizes the rotation of the material discharge chute 3 around the hinge point, and provides the material discharge chute 3 with an instantaneous upward thrust through the sliding column 45, thereby realizing the swing away from one end of the discharge port 11. The connecting mechanism includes a mounting plate 43 arranged between the cam 42 and the drive motor 41, and a limit block 44 is arranged on the mounting plate 43. A sliding column 45 is arranged through the limit block 44, and the sliding column 45 is arranged away from the discharge port 11 relative to the support column 5. The sliding column 45 can slide in the vertical direction along the limit block 44, and a push plate 46 is installed at the bottom end of the sliding column 45, and the cam 42 can push the push plate 46 to move upward. The upper end of the sliding column 45 passes through the discharge platform 2 and can contact the material discharge chute 3, and the push plate 46 can push the material discharge chute 3 upward through the sliding column 45.

[0033] Secondly, in order to ensure that the push plate 46 does not contact the cam 42 when it is at the lowest end, that is, when the position with the larger diameter of the cam 42 is facing upwards, the two are in a separated state, a spring 47 is sleeved on the outer side of the slide post 45, and one end of the spring 47 is connected to the limit block 44, and the other end is connected to the push plate 46, and the lowest point that the push plate 46 can reach is set non-contact with the cam 42. When the protruding position of the cam 42 rotates to away from the discharge chute 3, the slide post 45 slides downward, and under the elastic action of the spring 47, the push plate 46 can be pulled to be set non-contact with the cam 42, so that when the protruding position of the cam 42 can be rotated to the side close to the discharge chute 3, an instantaneous upward thrust can be generated on the push plate 46, and then the discharge chute 3 can be instantly pushed by the slide post 45, which plays a vibrating role and can further accelerate the speed at which the dovetail pad slides out.

[0034] On the basis of the above structure, the hinge point of the feed chute 3 is longer from one end of the feed chute 3 close to the driving mechanism 4 than from the other end. On the one hand, it can prevent the feed chute 3 from rotating too much and causing the material to fly out of the feed chute 3. On the other hand, it can make the gravity of the right part of the feed chute 3 greater than that of the left part. The end close to the discharge port 11 can move downward by its own weight and the gravity of the dovetail pad. Moreover, the maximum height that can be reached by the end of the feed chute 3 close to the discharge port 11 is not higher than the discharge port 11, so that the dovetail pads passing through the discharge port 11 can all fall into the feed chute 3. In order to further prevent the dovetail pads from flying out of the feed chute 3, a plurality of baffle plates 8 are arranged at intervals at the upper end of the feed chute 3, and the baffle plates are located at the upper end of the U-shaped opening of the feed chute 3.

[0035] It should be noted that a buffer pad 6 is provided at the bottom of the feed chute 3, and a contact plate 7 is installed on the lower side of the buffer pad 6. The contact plate 7 is provided in contact with the upper end of the sliding column 45. Through the setting of the buffer pad 6, the impact on the feed chute 3 when the sliding column 45 moves upward can be reduced, and by setting the contact plate 7, the contact plate 7 is made of a hard material, which can ensure the impact force of the sliding column 45 on it and ensure the vibration degree of the feed chute 3.

[0036] Secondly, the upper end of the sliding column 45 is set to a spherical surface, and the side of the contact plate 7 that contacts the sliding column 45 is set to an arc shape, which can reduce the friction of the sliding column 45 on the contact plate 7 during the up and down movement, thereby increasing the service life of both. In addition, the side of the push plate 46 close to the cam 42 is also set to an arc shape, so that it can be adapted to the outer edge surface of the cam 42 to reduce wear. When the degree of wear is large, in order to facilitate the replacement of the push plate 46, a threaded column 48 is set at the upper end of the push plate 46, and is installed with the bottom end of the sliding column 45 through threads.

[0037] Specifically, when the driving mechanism 4 is not started, one end of the material chute 3 close to the discharge port 11 falls on the supporting column 5, the end of the cam 42 with a larger diameter is located above, and the upper end of the sliding column 45 contacts the contact plate 7. There is no pressure between the two, and the spring 47 pushes the push plate 46 to the lowest end, which is non-contact with the cam 42. When unloading, the dovetail pad falls into the material chute 3 at the discharge port 11, and the driving motor 41 is started to drive the cam 42 to rotate. The protruding position of the cam 42 instantly pushes the push plate 46 to move upward, and a thrust is generated on the material chute 3 through the sliding column 45. The cam 42 continues to rotate, and the material chute 3 falls. The reciprocating motion forms vibration, which accelerates the sliding of the material, and the end of the material chute 3 away from the discharge port 11 swings up and down, which accelerates the sliding speed of the material.
