Description

Technical Field

[0001] The utility model relates to the field of punching machines, in particular to a material unloading auxiliary system of a punching machine. Background Art

[0002] A stamping machine is a processing equipment that applies external force to a plate (or pipe, profile, etc.) through a die to cause it to undergo plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size.

[0003] In order to improve work efficiency, the unloading process of the current stamping machine is mostly carried out by automated devices, such as the automatic unloading device for stamping machine disclosed in CN220717580U, which includes a stamping machine body. The device also includes: a storage mechanism for storing thin plate workpieces to be processed; a gripping mechanism for gripping the thin plate workpieces in the storage mechanism; a conveying mechanism for conveying the thin plate workpieces gripped by the gripping mechanism to the stamping machine body for stamping; a unloading mechanism for pushing the workpiece after stamping from the die into a workpiece collection box; the unloading mechanism includes a unloading cylinder arranged on one side of the stamping machine body and a unloading push rod serving as the power output end of the unloading cylinder, the workpiece collection box is arranged on the other side of the stamping machine body opposite to the unloading cylinder, and the unloading push rod can move toward the stamping area of ​​the stamping machine body under the drive of the unloading cylinder.

[0004] In practical applications, such as the above unloading device, the temporary storage mechanism containing the workpiece (such as: workpiece collection box) still needs to be manually transported, which has the following defects:

[0005] First, when temporary storage facilities are too close, they take up a lot of working space and pose a safety hazard.

[0007] Third, the temporary storage mechanism needs to be reorganized during use to improve safety and transfer efficiency, which further increases production costs. If the temporary storage mechanism is too small, multiple transfers are required; if the temporary storage mechanism is too large, the transfer is difficult. Utility Model Content

[0103] Working principle and usage:

[0104] The first step is pre-setting:

[0105] Mount the unit to the side of a press (or other processing equipment).

[0106] Press the start switch to power on the device for debugging. Place the empty storage box structure under the grabbing carrier 402. Adjust the preset value of the PLC control program according to the size or quality of the product.

[0107] The second step is to undertake:

[0108] The products processed by the stamping machine are placed in the rectangular through tube 201; when the total amount of the products reaches the preset value, the pressure sensor module outputs a signal to the PLC controller, and the PLC controller outputs a signal to the push rod motor 203 and the electric telescopic rod 204; the electric telescopic rod 204 drives the connecting chute 205 to move, so that one end of the connecting chute 205 is located below the rectangular through tube 201 and the other end is located above the chain conveyor device 1; the push rod motor 203 delays and drives the movable gate 202 to withdraw, so that the products enter the interval (composed of the partition plate 302 and the flexible skirt baffle 303) of the chain conveyor device 1 from the connecting chute 205. After that, the push rod motor 203 and the electric telescopic rod 204 are reset in sequence.

[0109] The distance sensor module 1 outputs a signal to the PLC controller, and the PLC controller outputs a signal to the screw stepper motor 1 401, the gripper motor 1 404, and the electric telescopic rod 2 403. The electric telescopic rod 2 403 drives the gripper motor 1 404 to move downward to grab the storage box mechanism. Then, the screw stepper motor 1 401 and the electric telescopic rod 2 403 transfer the storage box mechanism to the interval (composed of the "T"-shaped partition 305) of the chain conveyor device 2.

[0110] Then, the PLC controller outputs a signal to the chain conveyor device 1 301 and the chain conveyor device 2; the chain conveyor device 1 301 and the chain conveyor device 2 are started, driving the corresponding product or storage box mechanism to move a unit distance, thereby freeing up corresponding space for subsequent products or storage box mechanisms.

[0111] The third step is storage:

[0112] When the product on the chain conveyor device 1 enters the storage box mechanism, the infrared obstacle avoidance sensor module outputs a signal to the PLC controller, and the PLC controller outputs a signal to the chain conveyor device 2 304. The chain conveyor device 2 304 is started, so that the storage box mechanism containing the product moves to the bottom of the distance sensor module 2; the distance sensor module 2 outputs a signal to the PLC controller, and the PLC controller outputs a signal to the electric telescopic rod 3 405 and the screw stepper motor 2 407.

[0113] The electric telescopic rod 3 405 drives the correction carrier 406 to move downward, and the screw stepper motor 2 407 drives the trapezoidal partition plate 1 408 to move. The trapezoidal partition plate 1 408 starts to move from the trapezoidal partition plate 2 502, and moves back and forth in an orderly manner, so that the products are evenly distributed in the storage box mechanism. After the end, the electric telescopic rod 3 405 drives the correction carrier 406 to reset.

[0114] Afterwards, the chain conveyor device 2 304 is started, so that the storage box mechanism containing the product moves to the bottom of the distance sensor module 3; the distance sensor module 3 outputs a signal to the PLC controller, and the PLC controller outputs a signal to the screw stepper motor 3 409, the electric telescopic rod 411, and the clamping jaw motor 2 412.

[0115] The screw stepper motor three 409 drives the retrieval carrier plate 410 to move above the storage box mechanism; the electric telescopic rod four 411 delays and drives the clamping claw motor two 412 to move downward to grab the storage box mechanism.

[0116] Afterwards, the screw stepper motor three 409 and the electric telescopic rod four 411 transfer the storage box mechanism to the movable end of the electric lifting device 413, and the movable end of the electric lifting device 413 moves down a unit distance to facilitate the subsequent storage of the storage box mechanism.

[0117] Step 4: Uninstall:

[0118] When the unloading switch is pressed, the PLC controller outputs a signal to the electric lifting device 413, and the movable end of the electric lifting device 413 moves to a position slightly higher than the rectangular through hole 1, so as to facilitate unloading.

[0119] Embodiment 2, on the basis of embodiment 1, an electric telescopic rod is additionally provided between the connecting slide groove 205 and the limiting slider 206 to improve adaptability.
