Description

Technical Field

[0001] This utility model relates to the technical field of cold heading machine equipment, and in particular to an automatic feeding device for a cold heading machine. Background Technology

[0002] With the advancement of technology, fasteners such as bolts, screws, and rivets are often forged using cold heading machines. Cold heading machines use a cold heading method to forge the heads of bolts and rivets, directly forming them into the required shape and size, thereby significantly improving production efficiency.

[0003] The existing feeding device for cold heading machines has the following disadvantages: it requires manual placement of the blank on the feeding platform, and the blank is clamped by a manual clamping mechanism on the feeding platform and transferred to the mold of the cold heading machine for cold heading. This manual feeding method requires workers to stay by the equipment for a long time to perform repetitive and simple work, which wastes labor costs, has low production efficiency, and poses certain safety hazards. Utility Model Content

[0004] This utility model proposes an automatic feeding device for a cold heading machine, which solves the problems of the existing cold heading machine using manual feeding, which wastes labor costs, has low production efficiency, and poses certain safety hazards.

[0005] The technical solution of this utility model is implemented as follows:

[0006] This utility model provides an automatic feeding device for a cold heading machine, including a vibratory feeder, a conveying mechanism, a pushing mechanism, a guiding mechanism, and a robot. The discharge port of the vibratory feeder is connected to the loading port of the conveying mechanism. The pushing mechanism is located at the unloading end of the conveying mechanism and is used to push the blank output by the conveying mechanism to the guiding mechanism. The guiding mechanism is used to guide the blank into a storage tank. The robot is used to transfer the blank in the storage tank into the mold of the mold base.

[0007] Specifically, the conveying mechanism includes a frame on which a conveyor belt and a first driving component are mounted. Side plates are provided on both sides of the conveyor belt, and the distance between the two side plates matches the diameter of the blank. The first driving component is used to drive the conveyor belt to convey the blank along the axial direction.

[0008] Specifically, the pushing mechanism includes a bracket installed on the outside of the material feeding end of the conveying mechanism. A second driving component is installed on the bracket. A push plate is installed on the telescopic end of the second driving component. The second driving component is used to drive the push plate to extend and retract in a direction perpendicular to the conveying direction of the conveying mechanism, so as to push the blank output by the conveying mechanism into the guiding mechanism.

[0009] Furthermore, a downwardly inclined transition plate is connected between the feeding end of the conveying mechanism and the guiding mechanism, and the pushing mechanism pushes the blank from the feeding end of the conveying mechanism through the transition plate and rolls into the guiding mechanism.

[0010] Furthermore, the telescopic end of the second driving component is also equipped with a baffle plate. The distance between the baffle plate and the push plate is matched with the diameter of the blank, and the vertical gap between the bottom end of the baffle plate and the conveying mechanism is smaller than the diameter of the blank. When the second driving component drives the push rod and the baffle plate to extend above the transition plate, the vertical gap between the bottom end of the baffle plate and the transition plate is larger than the diameter of the blank.

[0011] Furthermore, a position sensor is installed at the feeding end of the conveying mechanism to detect whether the blank at the feeding end of the conveying mechanism has been conveyed to the correct position. The position sensor is linked to the second drive component for control.

[0012] Specifically, the material guiding mechanism includes a downwardly inclined guide plate, on which two parallel limiting strips are installed, the distance between the two limiting strips matching the length of the blank; a pressure strip is installed on the inner side of the limiting strip, the pressure strip is fixedly connected to the limiting strip through a connecting seat, and the distance between the pressure strip and the guide plate matching the diameter of the blank.

[0013] Furthermore, a baffle is installed at the end of the pressure strip, and the distance between the baffle and the material discharge end of the guide plate is greater than the diameter of the blank; a sliding plate is provided below the material discharge end of the guide plate, and the storage groove is opened on the top surface of the sliding plate, and the distance between the baffle and the sliding plate is less than the diameter of the blank; the sliding plate is installed at the telescopic end of the third driving component, and the third driving component is used to drive the sliding plate to telescopically move in the horizontal direction; when the third driving component drives the sliding plate to extend forward to the material transfer station, the blank in the storage groove is picked up by the robot and transferred to the mold; when the third driving component drives the sliding plate to retract backward to the storage station, the next blank rolling off the material discharge end of the guide plate falls into the storage groove under the obstruction of the baffle.

[0014] Preferably, the guide plate has several adjustment holes along the length of the blank, which are used to adjust the spacing between the two limiting strips according to the length of the blank.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] (1) This utility model achieves automatic feeding, directional conveying, precise positioning and transfer of cold heading machine blanks through the coordinated cooperation of vibratory feeder, conveying mechanism, pushing mechanism, guiding mechanism and robot, which significantly improves the level of production automation; this design replaces the traditional manual feeding, effectively reduces labor costs, improves production efficiency, eliminates safety hazards, and ensures the stability and positioning accuracy of blanks during conveying and transfer.

[0017] (2) By setting side plates with a spacing matching the diameter of the blank on both sides of the conveyor belt, and combining the first driving component to drive the conveyor belt to transport the blank along the axial direction, this utility model ensures that the blank maintains its directional arrangement during the conveying process, avoids deviation or jamming, and provides a stable and continuous material supply basis for subsequent processes.

[0018] (3) The present invention drives the push plate to push the blank vertically through the second drive component, and cooperates with the baffle plate to restrict the position of the blank; when pushing the blank, the gap between the baffle plate and the transition plate increases so that the blank rolls down smoothly; when resetting, the gap between the baffle plate and the conveying mechanism decreases so as to block the new blank, thereby realizing the individual pushing of each blank and improving the reliability of the action.

[0019] (4) This utility model sets parallel limiting strips and pressure strips on the guide plate. The spacing between the limiting strips matches the length of the blank, and the spacing between the pressure strip and the guide plate matches the diameter of the blank. The double limiting makes the blank axially stable when it rolls along the inclined guide plate, preventing deflection or derailment, and ensuring that the blank falls accurately into the storage tank.

[0020] (5) This utility model uses a third driving component to drive the sliding plate to switch between the storage station and the transfer station: when retracted, the baffle blocks the blank material so that it falls accurately into the storage trough; when extended, the robot arm picks up the blank material in the trough and transfers it. This design realizes the separation of the timing of storage and retrieval, ensuring that the guide channel can still continuously supply material when the robot arm is operating, thus improving cycle efficiency;

[0021] (6) By opening adjustment holes along the length of the blank on the guide plate, the spacing of the limiting strips can be adjusted according to different blank lengths; this structure enhances the versatility of the equipment, can adapt to the production needs of multiple specifications of products, and reduces changeover time and cost.

[0032] The technical solution of this utility model will be clearly and completely described below with reference to its embodiments. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0033] Reference Figures 1 to 8 This utility model provides an automatic feeding device for a cold heading machine, including a vibratory feeder (not shown in the figure), a conveying mechanism 1, a pushing mechanism 2, a guiding mechanism 3, and a robot (not shown in the figure). The discharge port of the vibratory feeder is connected to the feeding port of the conveying mechanism 1. The pushing mechanism 2 is located at the unloading end of the conveying mechanism 1 and is used to push the blank output by the conveying mechanism 1 to the guiding mechanism 3. The guiding mechanism 3 is used to guide the blank into the storage tank 22. The robot is used to transfer the blank in the storage tank 22 into the mold 5 of the mold base 4.

[0034] This utility model achieves automatic feeding, directional conveying, precise positioning and transfer of blanks for cold heading machines through the coordinated operation of a vibratory feeder, conveying mechanism 1, pushing mechanism 2, guiding mechanism 3 and robotic arm, significantly improving the level of production automation. This design replaces traditional manual feeding, effectively reducing labor costs, improving production efficiency, eliminating safety hazards, and ensuring the stability and positioning accuracy of the blanks during conveying and transfer.

[0035] Specifically, such as Figure 3 , 4 As shown, the conveying mechanism 1 includes a frame 6, on which a conveyor belt 7 and a first driving component 8 are mounted. Side plates 9 are provided on both sides of the conveyor belt 7, and the distance between the two side plates 9 matches the diameter of the blank. The first driving component 8 is used to drive the conveyor belt 7 to convey the blank axially. By setting side plates 9 on both sides of the conveyor belt 7 with a distance matching the diameter of the blank, and combining the first driving component 8 to drive the conveyor belt 7 to convey the blank axially, it is ensured that the blank maintains its directional arrangement during the conveying process, avoiding deviation or jamming, and providing a stable and continuous feeding foundation for subsequent processes.

[0036] In this embodiment, the first driving component 8 may use a motor as the driving source.

[0037] Specifically, such as Figure 3 , 4 As shown, the pushing mechanism 2 includes a bracket 10 installed on the outside of the material feeding end of the conveying mechanism 1. A second driving component 11 is installed on the bracket 10. A push plate 12 is installed on the telescopic end of the second driving component 11. The second driving component 11 is used to drive the push plate 12 to extend and retract in a direction perpendicular to the conveying direction of the conveying mechanism 1, so as to push the blank output by the conveying mechanism 1 into the guiding mechanism 3.

[0038] In this embodiment, the second driving component 11 can be a cylinder as the driving source. In specific implementation, a hydraulic cylinder, linear motor or the like can also be used as the driving source.

[0039] Furthermore, such as Figure 3-5 As shown, a downwardly inclined transition plate 13 is connected between the feeding end of the conveying mechanism 1 and the guiding mechanism 3. The pushing mechanism 2 pushes out the blank from the feeding end of the conveying mechanism 1, so that the blank automatically rolls down to the guiding mechanism 3 by gravity after being pushed.

[0040] Furthermore, such as Figure 3-5As shown, a baffle plate 14 is also installed on the telescopic end of the second driving component 11. The distance between the baffle plate 14 and the push plate 12 matches the diameter of the blank (the blank is conveyed by the conveyor belt 7 to the space between the baffle plate 14 and the push plate 12). The vertical gap between the bottom end of the baffle plate 14 and the conveying mechanism 1 is smaller than the diameter of the blank. When the second driving component 11 drives the push rod and the baffle plate 14 to extend above the transition plate 13, the vertical gap between the bottom end of the baffle plate 14 and the transition plate 13 is larger than the diameter of the blank. The second driving component 11 drives the push plate 12 to push the blank vertically, and cooperates with the baffle plate 14 to restrict the position of the blank. When pushing the blank, the gap between the baffle plate 14 and the transition plate 13 increases, allowing the blank to roll down smoothly. When resetting, the gap between the baffle plate 14 and the conveying mechanism 1 decreases, which can block new blanks, realizing the individual pushing of each blank and improving the reliability of the operation.

[0041] In this embodiment, the baffle plate 14 is a "7" shaped plate. The horizontal end of the baffle plate 14 is fixedly connected to the telescopic end of the second drive component 11, and the vertical end of the baffle plate 14 is spaced apart from the push plate 12 and the conveyor belt 7.

[0042] Furthermore, such as Figure 3 , 4 As shown, a position sensor 15 is installed at the feeding end of the conveying mechanism 1 to detect whether the blank at the feeding end of the conveying mechanism 1 has been conveyed to the correct position. The position sensor 15 is linked to the second drive component 11 for control. By installing the position sensor 15 at the feeding end of the conveying mechanism 1, the pusher mechanism 2 is activated after the blank is detected to be in place. This automated cycle control ensures accurate timing of the push, avoids empty pushing or material accumulation, and improves the continuity of system operation. The position sensor 15 in this embodiment can be a contact type (such as piezoelectric sensing type) or a non-contact type (such as photoelectric sensing type) sensor.

[0043] Specifically, such as Figure 6-8 As shown, the guiding mechanism 3 includes a downwardly inclined guiding plate 16. Two parallel limiting strips 17 are installed on the guiding plate 16, and the distance between the two limiting strips 17 matches the length of the blank. A pressure strip 18 is installed on the inner side of the limiting strip 17. The pressure strip 18 is fixedly connected to the limiting strip 17 through a connecting seat 19, and the distance between the pressure strip 18 and the guiding plate 16 matches the diameter of the blank. By setting parallel limiting strips 17 and pressure strips 18 on the guiding plate 16, the distance between the limiting strips 17 matches the length of the blank, and the distance between the pressure strips 18 and the guiding plate 16 matches the diameter of the blank. The double limiting ensures that the blank remains axially stable when rolling along the inclined guiding plate 16, preventing deflection or derailment, and ensuring that the blank falls accurately into the storage trough 22 (in this embodiment, only one blank can be stored in the storage trough 22).

[0044] Furthermore, such as Figure 6-8As shown, a baffle 20 is installed at the end of the pressure strip 18, and the distance between the baffle 20 and the material discharge end of the guide plate 16 is greater than the diameter of the blank; a sliding plate 21 is provided below the material discharge end of the guide plate 16, and the material storage groove 22 is opened on the top surface of the sliding plate 21, and the distance between the baffle 20 and the sliding plate 21 is less than the diameter of the blank; the sliding plate 21 is installed at the telescopic end of the third driving component (not shown in the figure), and the third driving component is used to drive the sliding plate 21 to telescopically move in the horizontal direction; when the third driving component... When the sliding plate 21 driven by the component extends forward to the material transfer station, the robot arm picks up the blank in the storage slot 22 and transfers it into the mold 5. When the sliding plate 21 driven by the third driving component retracts backward to the storage station, the next blank rolling off the guide plate 16 falls into the storage slot 22 under the obstruction of the baffle 20. The sliding plate 21 is switched between the storage station and the material transfer station by the third driving component: when retracted, the baffle 20 prevents the blank from falling accurately into the storage slot 22; when extended, the robot arm picks up the blank in the slot and transfers it. This design achieves the separation of the timing of material storage and material retrieval, ensuring that the guide channel can still continuously supply material during robot arm operation, thus improving cycle efficiency.

[0045] In this embodiment, the third driving component can be a cylinder as the driving source. In specific implementation, a hydraulic cylinder, linear motor, or the like can also be used as the driving source.

[0046] Preferably, such as Figure 6 As shown, the guide plate 16 has several adjustment holes 23 along the length of the blank, which are used to adjust the spacing between the two limiting strips 17 according to the length of the blank. By opening adjustment holes 23 along the length of the blank on the guide plate 16, the spacing between the limiting strips 17 can be adjusted according to different blank lengths. This structure enhances the versatility of the equipment, can adapt to the production needs of multiple specifications of products, and reduce changeover time and cost.

[0047] In this embodiment, both the vibratory feeder and the robotic arm are existing technologies. The vibratory feeder can be directly adopted from the vibratory feeder in the applicant's earlier patent application (publication number CN208555829U); the robotic arm can be directly adopted from the gripping and feeding mechanism in the applicant's earlier patent application (publication number CN118595355A).

[0048] The workflow of the feeding device in this embodiment is as follows:

[0049] 1) Orientation and conveying of raw materials

[0050] Vibratory feeder: Automatically arranges disordered blanks into a uniform orientation and conveys them to conveying mechanism 1 through the discharge port.

[0051] Conveying mechanism 1: The conveyor belt 7, constrained by the two side plates 9 (with spacing matching the blank diameter), is driven by the first driving component 8, so that the blank is conveyed axially to the unloading end.

[0052] 2) Bulk positioning and pushing

[0053] Position detection: Position sensor 15 at the feeding end detects whether the blank is in place.

[0054] Pushing action: When the blank is in place, the second drive component 11 drives the push plate 12 and the baffle plate 14 to extend synchronously;

[0055] Functions of baffle plate 14: Before extension: The gap between the bottom end of baffle plate 14 and conveyor belt 7 is less than the diameter of the blank, preventing the blank from rolling down in a disorderly manner; When extension: The gap between the bottom end of baffle plate 14 and transition plate 13 is greater than the diameter of the blank, and the blank is pushed out by push plate 12 and rolls down along inclined transition plate 13 to guide mechanism 3.

[0056] 3) Feeding and Temporary Storage

[0057] Material guiding channel: The blank enters the guide plate 16 and rolls axially within the limiting channel formed by the limiting strip 17 (spacing matches the blank length) and the pressure strip 18 (perpendicular to the guide plate 16 and spacing matches the blank diameter).

[0058] Material storage control: When the blank rolls to the end of the guide plate 16, it is blocked by the baffle 20; when the sliding plate 21 is in the storage position (retracted state): the gap between the baffle 20 and the sliding plate 21 is less than the diameter of the blank, and the blank falls accurately into the storage tank 22.

[0059] 4) Transfer the blank to the mold 5

[0060] Station switching: The third drive component drives the sliding plate 21 to extend forward to the material transfer station.

[0061] Robot operation: The robot grips the blank in the storage tank 22 and transfers it to the mold 5 in the cold heading machine mold base 4.

[0062] 5) Continuous feeding cycle

[0063] Sliding plate 21 reset: After the transfer is completed, the third driving component drives the sliding plate 21 to retract and return to its original position;

[0064] Next blank replenishment: During the reset process of sliding plate 21, the next blank on guide plate 16 rolls to baffle 20 to wait, and immediately falls into storage tank 22 after sliding plate 21 is in place.

[0065] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
