Description

Technical Field

[0001] This utility model belongs to the field of vibratory feeder technology, and in particular relates to a vibratory feeder feeding mechanism for fine punching punch processing. Background Technology

[0002] Fine blanking punches are the core mold components that determine the final head shape, dimensional accuracy, and surface quality of bolts and screws. They typically include Phillips head punches and internal hexagonal head punches, and are generally manufactured using metals such as high-speed steel.

[0003] When finishing fine blanking punches, a vibratory feeder is usually used to feed the rough-formed fine blanking punches. Since the fine blanking punch is cylindrical, the traditional vibratory feeder can only transport and feed the fine blanking punches in a simple way. It cannot screen the fine blanking punches that are in different postures during feeding, and cannot ensure that the fine blanking punches maintain a uniform posture during feeding, which leads to the need for secondary adjustments and thus affects the efficiency of subsequent finishing. Utility Model Content

[0004] The purpose of this utility model is to address the aforementioned technical problems by providing a vibratory feeder mechanism for fine blanking punch processing, which achieves the effect of keeping the fine blanking punch in a uniform posture during vibratory feeder feeding.

[0005] In view of this, the present invention provides a vibratory feeder feeding mechanism for fine blanking punch processing, comprising: A vibratory feeder, including a base and a feed pan, is used for feeding fine blanking punches; The discharge track is connected to the material tray and is used to guide the fine punching head out of the material tray; The screening track, connected to the discharge track, includes an inclined base plate and an arc-shaped side plate perpendicular to the base plate, and the arc-shaped side plate is used to screen the attitude of the fine punch during the conveying process. A recycling hopper, installed below the screening track, is used to collect the fine punches that have been rejected by the screening process. The fine blanking punches on the screening track can be in three positions: upright, inverted, and tilted. The arc-shaped side plate is used to hold the fine blanking punches in the upright position for conveying, and to make the fine blanking punches in the inverted and tilted positions fall into the recycling hopper.

[0006] In the above technical solution, further: The tilting posture includes a first tilting posture and a second tilting posture that are perpendicular to each other; The first tilting posture is such that the axis of the fine punch is perpendicular to the tangential direction of the fine punch conveyed on the screening track.

[0007] In the above technical solution, further: The height dimension of the curved side plate perpendicular to the base plate is smaller than the radius dimension of the fine blanking punch.

[0008] In the above technical solution, further: The recycling hopper is tilted, and the lowest position has a discharge port.

[0009] In the above technical solution, further: The bottom plate is tilted downwards in the vertical direction at the end away from the discharge track and downwards in the vertical direction on the side of the bottom plate near the arc-shaped side plate.

[0010] In the above technical solution, further: The bottom plate is arranged at an angle α of 10-15° that is inclined downwards along the vertical direction at the end away from the discharge track; The bottom plate is arranged at an angle β of 15-20° that is inclined downward in the vertical direction on the side closest to the curved side plate.

[0011] In the above technical solution, further: The bottom plate has a widened section on the side away from the discharge track.

[0012] Furthermore, the above technical solution also includes: The torsion track, connected to the side of the screening track away from the discharge track, is used to adjust the feeding direction of the fine punch.

[0013] The beneficial effects of this utility model are as follows: 1. By using the screening track of the inclined base plate and the arc-shaped side plate, fine blanking punches in the inverted and tilted positions are screened and rejected, so that only the fine blanking punches in the upright position are allowed to follow the screening track. This ensures that the fine blanking punches maintain a uniform posture during feeding, avoids the need for secondary adjustments later, and ensures the efficiency of subsequent finishing.

[0014] 2. The inclined recycling hopper automatically collects rejected workpieces at the lowest discharge port, effectively preventing workpieces from piling up in the recycling hopper and overflowing the screening track, thus avoiding interference with the normal conveying and screening process.

[0015] 3. By setting the height of the arc-shaped side plate perpendicular to the base plate to be less than the radius of the fine punch, the overturning resistance of the fine punch in the inverted and tilted positions is reduced, while ensuring that the center of gravity of the upright fine punch is stably placed on the screening track. This makes it easier for the fine punch to overturn over the arc-shaped side plate and fall, thus ensuring the accuracy and effectiveness of screening. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0018] Example 1:

[0019] This embodiment provides a vibratory feeder mechanism for fine blanking punch processing, including: The vibratory feeder, including a base 1 and a feed tray 2, is used for feeding the fine punch 7; The discharge track 3 is connected to the material tray 2 and is used to guide the fine punch 7 out of the material tray 2; The screening track 4 is connected to the discharge track 3 and includes an inclined base plate 40 and an arc-shaped side plate 41 perpendicular to the base plate 40. The arc-shaped side plate 41 is used to screen the attitude of the fine punch 7 during the conveying process. The recycling hopper 5 is installed below the screening track 4 and is used to collect the fine punches 7 that have been screened out. Among them, the attitudes of the fine punch 7 on the screening track 4 include upright attitude, inverted attitude and tilted attitude, while the arc-shaped side plate 41 is used to hold the fine punch 7 in the upright attitude for conveying, and to make the fine punch 7 in the inverted attitude and tilted attitude fall into the recycling hopper 5. Among them, the bottom plate 40 and the arc-shaped side plate 41 are adapted to each other, that is, the bottom plate 40 is also arc-shaped. Meanwhile, the vibratory feeder also includes a vibration mechanism, which are all conventional structures of existing vibratory feeders and are well known to those skilled in the art, so they will not be described in detail here.

[0020] As can be seen from this embodiment, by setting the screening track 4, when the fine punch 7 is in the upright position, its axial bottom surface is attached to the inclined base plate 40, and its side surface is attached to the arc-shaped side plate 41, ensuring that its center of gravity is on the screening track 4. Then, under the vibration of the vibrating plate, after entering the screening track 4 from the discharge track 3, it is conveyed along the screening track 4. When the fine punch 7 is in an inverted or tilted position, because there is a protrusion on the axial top surface of the fine punch 7, when it is inverted, the protrusion contacts the inclined base plate 40. When the fine punch 7 moves along the screening track 4, it will tilt and fall off the screening track 4 into the recycling hopper 5. When the fine punch 7 is in a tilted state, its axial end contacts the arc-shaped side plate 41, and its fit with the screening track 4 is poor. Therefore, under the vibration of the vibrating plate, it is also easy to fall off the screening track 4 into the recycling hopper 5. This ensures that the fine punch 7 maintains a uniform posture during material feeding, avoiding subsequent secondary adjustments and ensuring the efficiency of subsequent finishing processes.

[0021] Example 2:

[0022] This embodiment provides a vibratory feeder mechanism for fine blanking punch processing. In addition to the technical solutions of the above embodiments, it also has the following technical features: The tilting posture includes a first tilting posture and a second tilting posture that are perpendicular to each other; The first tilting posture is such that the axis of the fine punch 7 is perpendicular to the tangential direction of the fine punch 7 being conveyed on the screening track 4.

[0023] As can be seen from this embodiment, when the fine punch 7 is in different tilting postures, that is, when the axis of the fine punch 7 is perpendicular to the tangent direction of the fine punch 7 being conveyed on the screening track 4, it is in the first tilting posture. When the fine punch 7 is conveyed along the screening track 4, the contact effect between the fine punch 7 and the screening track 4 is poor. Therefore, it is easy to fall off the screening track 4 and into the recycling hopper 5 under the vibration of the vibrating plate. When the axis of the fine punch 7 is parallel to the tangent direction of the fine punch 7 being conveyed on the screening track 4, it is in the second tilting posture. When the fine punch 7 is conveyed along the screening track 4, the contact effect between the radial side and the arc-shaped side plate 41 is also poor. Therefore, it is also easy to fall off the screening track 4 and into the recycling hopper 5 under the vibration of the vibrating plate.

[0024] Example 3:

[0025] This embodiment provides a vibratory feeder mechanism for fine blanking punch processing. In addition to the technical solutions of the above embodiments, it also has the following technical features: The height dimension of the arc-shaped side plate 41, perpendicular to the base plate 40, is smaller than the radius dimension of the fine blanking punch 7.

[0026] As can be seen from this embodiment, by setting the height dimension of the arc-shaped side plate 41 perpendicular to the base plate 40 to be smaller than the radius dimension of the fine punch 7, when the center of gravity of the fine punch 7 in the upright position is located on the screening track 4, it makes it easier for the fine punch 7 in the inverted and tilted positions to cross the arc-shaped side plate 41 and fall off the screening track 4, thus ensuring the screening effect of the fine punch 7.

[0027] Example 4:

[0028] This embodiment provides a vibratory feeder mechanism for fine blanking punch processing. In addition to the technical solutions of the above embodiments, it also has the following technical features: The recycling hopper 5 is tilted, and a discharge port is opened at the lowest position; The discharge port is equipped with a collection frame, and the collected fine punches 7 are manually poured back into the material tray 2 of the vibratory feeder. This is a routine operation for those skilled in the art and will not be described in detail here. Meanwhile, the discharge port at the lowest position of the recycling hopper 5 is not shown in the attached drawings of this application specification, as it is a standard setting for those skilled in the art and will not be described in detail here.

[0029] As can be seen from this embodiment, by tilting the recycling hopper 5 and opening a discharge port at the lowest position, it is convenient to collect the fine punches 7 that have fallen onto the screening track 4, and avoid the recycling hopper 5 accumulating a large number of fine punches 7 and overflowing the screening track 4, thereby avoiding the impact on the fine punches 7 falling from the screening track 4 or being conveyed on the screening track 4.

[0030] Example 5:

[0031] This embodiment provides a vibratory feeder mechanism for fine blanking punch processing. In addition to the technical solutions of the above embodiments, it also has the following technical features: The bottom plate 40 is inclined as follows: the end of the bottom plate 40 away from the discharge track 3 is inclined downward in the vertical direction, and the side of the bottom plate 40 near the arc-shaped side plate 41 is inclined downward in the vertical direction.

[0032] As can be seen from this embodiment, by setting the bottom plate 40 to be inclined downward in the vertical direction at the end of the bottom plate 40 away from the discharge track 3 and downward in the vertical direction at the side of the bottom plate 40 near the arc-shaped side plate 41, it is convenient for the fine punch 7 to be conveyed and moved along the screening track 4 under the vibration of the vibrating plate. On the other hand, it is convenient for the fine punch 7 in the inverted and tilted positions to fall off the screening track 4 over the arc-shaped side plate 41 when the center of gravity of the fine punch 7 in the upright position is located on the screening track 4.

[0033] Example 6:

[0034] This embodiment provides a vibratory feeder mechanism for fine blanking punch processing. In addition to the technical solutions of the above embodiments, it also has the following technical features: The bottom plate 40 is arranged at an angle α of 10-15° that is inclined downward in the vertical direction at the end away from the discharge track 3; The bottom plate 40 is arranged at an angle β of 15-20° that is inclined downward in the vertical direction on the side closest to the arc-shaped side plate 41.

[0035] As can be seen from this embodiment, by limiting the tilt angles α and β of the base plate 40 in two directions, it is convenient to adjust the center of gravity of the upright fine punch 7 onto the screening track 4, thus ensuring the stability of the upright fine punch 7 when it is conveyed along the screening track 4.

[0036] Example 7:

[0037] This embodiment provides a vibratory feeder mechanism for fine blanking punch processing. In addition to the technical solutions of the above embodiments, it also has the following technical features: The bottom plate 40 has a widened section 42 on the side away from the discharge track 3.

[0038] As can be seen from this embodiment, the widened portion 42 on the base plate 40 facilitates the improvement of the conveying stability of the upright fine punch 7 on the conveying section of the screening track 4 after screening, and reduces the possibility of it falling off the screening track 4.

[0039] Example 8:

[0040] This embodiment provides a vibratory feeder mechanism for fine blanking punch processing. In addition to the technical solutions described in the above embodiments, it also has the following technical features: The twisting track 6 is connected to the side of the screening track 4 away from the discharge track 3 and is used to adjust the feeding direction of the fine punch 7. The end of the torsion track 6 away from the screening track 4 is connected to the finishing equipment. The specific connection structure is known to those skilled in the art from conventional equipment and will not be described in detail here.

[0041] As can be seen from this embodiment, by twisting the track 6, the feeding direction of the fine punch 7, which has been screened and is in an upright position, is adjusted, which facilitates its adaptation to subsequent finishing equipment, further avoids possible secondary adjustments, and ensures the efficiency of subsequent finishing.

[0042] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other.
