[0030] Example

[0031] See also Figure 1-Figure 5 , a workpiece rapid positioning device for track plate blanking is composed of a transfer mechanism, a feeding mechanism, a detection mechanism and a positioning mechanism;

[0032] The transfer mechanism is installed at the feed port and discharge port of the press 1 to transfer materials and finished products; the feeding mechanism is installed at the feed port of the transfer mechanism, and the materials are fed to the press 1 for punching through the feeding mechanism; the detection mechanism is used to detect the material state and feed the detection signal back to the control system 2; the positioning mechanism is installed on the other side away from the feeding mechanism to center and limit the material.

[0033] In a specific implementation, the transfer mechanism is composed of a feeding conveyor belt 10 installed at the feed port of the press 1 and a conveying conveyor belt 11 installed at the discharge port of the press 1;

[0034] like Figure 5 As shown, the feeding mechanism is installed above the feeding conveyor belt 10. The feeding mechanism is provided with a pushing action arm 3 slidably installed on the lifting frame 4. The lifting frame 4 is also provided with a horizontal pushing rod 5. The other end of the horizontal pushing rod 5 is connected to the pushing action arm 3 and drives the pushing action arm 3 to push materials by telescoping. The lifting frame 4 is connected with a pushing lifting rod 6 for lifting movement; the other end of the pushing lifting rod 6 is also connected to a rodless cylinder 7, and the rodless cylinder 7 drives the feeding mechanism as a whole to perform horizontal displacement.

[0035] like Figure 3 As shown, the positioning mechanism is provided with a centering mechanism 8 symmetrically arranged on the front and rear sides of the mold of the press 1, and synchronously extends and retracts to push the material to the longitudinal center position; it is composed of a centering cylinder 801 and a centering frame 802 connected to the centering cylinder 801, and the two sets of centering frames 802 are slidably connected to the front and rear sides of the press 1, and the centering frame 802 is driven by the centering cylinder 801 to perform telescopic movement.

[0036] like Figure 4As shown, the positioning frame 9 of the positioning mechanism is provided with a positioning arm 901 whose end is close to the die of the press machine 1 for lateral limitation of the material, and the positioning arm 901 is also connected with a positioning lifting rod 902, which drives the positioning arm 901 to rise and fall to release the lateral limitation through the extension and contraction of the positioning lifting rod 902. The other end of the positioning lifting rod 902 is connected to a bracket 903 slidably mounted on the line body of the transfer mechanism, and the bracket 903 is slidably limited by a limiting mechanism 904. The limiting mechanism 904 is composed of a positioning pad 90401 for plug-in limitation and a slot 90402 whose height is lower than the bracket 903; wherein, the positioning pad 90401 is installed on the bracket 903 through a detachable connection, and the slot 90402 is provided in several groups on the line body of the transfer mechanism.

[0037] like Figure 2 As shown, the detection mechanism is provided with diffuse reflection photoelectric 12, induction contact 13, distance measurement photoelectric 14 and opposite reflection photoelectric 15.

[0038] Among them, the diffuse reflection photoelectric 12 is installed on the feeding conveyor belt 10 to monitor the feeding status of the material, the sensing contact 13 is installed on the positioning action arm 901 close to the mold end of the press 1 to monitor whether the material position is in place, the ranging photoelectric 14 is installed on the side of the mold of the press 1 to monitor the material length, and the reflected photoelectric 15 is installed on the conveying conveyor belt 11 to monitor the finished product transportation status.

[0039] It should be noted that the workpiece rapid positioning device for track shoe blanking in this embodiment is divided into first workpiece production condition control and continuous production condition control in actual use.

[0040] The specific control of the production condition of the first workpiece is as follows:

[0041] When the first workpiece is produced, the positioning lifting rod 902 of the positioning frame 9 is in the extended state by default, so that the positioning action arm 901 is in the limit working condition. When the workpiece on the feeding conveyor belt 10 is transported to the diffuse reflection photoelectric 12, the diffuse reflection photoelectric 12 feedbacks the signal to the control system 2. The control system 2 sends a control signal to the pusher lifting rod 6 to extend so that the pusher action arm 3 descends. The control system 2 again sends a command to the rodless cylinder 7 to extend and drive the pusher action arm 3 to move in the direction of the press 1, and at the same time sends a control signal to the horizontal pusher rod 5 through the control system 2 to extend the workpiece into the press. The material is fed until the workpiece contacts the inductive contact 13 on the positioning action arm 901. The control system 2 controls the centering cylinder 801 to extend and clamp the workpiece through the centering frame 802. The length of the workpiece is then detected by the ranging photoelectric 14. After it meets the process requirements, the signal is fed back to the control system 2. The press 1 is used for stamping and shearing. After the stamping and shearing is completed, the control system 2 sends a control command to retract the positioning lifting rod 902, the centering cylinder 801, the pushing lifting rod 6 and the horizontal pushing rod 5. The finished workpiece is transported out of the device through the conveyor belt 11.

[0042] The specific control of continuous production conditions is as follows:

[0043] During continuous production, the positioning lifting rod 902 of the positioning frame 9 is in a retracted state. The workpiece passes through the diffuse reflection photoelectric 12 and feeds back the signal to the control system 2. The control system 2 sends a control signal to the push lifting rod 6 to extend so that the push action arm 3 descends. The control system 2 again sends a command to the rodless cylinder 7 to extend and drive the push action arm 3 to move in the direction of the press 1, and at the same time sends a control signal to the horizontal push rod 5 through the control system 2 to extend and feed the workpiece. At this time, the finished product is pushed to the conveyor belt 11. The reflected photoelectric 15 detects the feedback signal after the finished product passes, and the control system 2 sends a control signal to the horizontal push rod 5 to extend and feed the workpiece. The positioning lifting rod 902 extends to make the positioning action arm 901 in the limit working condition. When the workpiece touches the inductive contact 13 on the positioning action arm 901, the control system 2 controls the centering cylinder 801 to extend and clamp the workpiece through the centering frame 802. Then, the workpiece length is detected by the distance measuring photoelectric 14. After meeting the process requirements, the signal is fed back to the control system 2, and the press 1 is used for stamping and blanking. After the blanking is completed, the control system 2 sends a control command to retract the positioning lifting rod 902, the centering cylinder 801, the pusher lifting rod 6 and the horizontal pusher rod 5, and the finished workpiece is conveyed out of the device through the conveyor belt 11. Repeat this step for subsequent production.

[0044] In this embodiment, the horizontal push rod 5 has no fixed length stroke, and whether the horizontal push rod 5 is in place depends on the workpiece touching the sensing contact 13, so it is suitable for workpieces of different lengths. The horizontal push rod 5, the push rod 6 and the positioning rod 902 in this embodiment use cylinders, but are not limited to cylinders. Those skilled in the art can make appropriate settings according to actual working conditions and needs.

[0045] At the same time, when changing the product model, it is only necessary to remove the positioning pad 90401 on the bracket 903, unplug it from the slot 90402, and plug it into the preset slot 90402 of other models to realize the overall displacement of the positioning frame 9, and finally install the positioning pad 90401 on the bracket 903 to perform operations on workpieces of different models.

[0046] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
