Description

Technical Field

[0001] This utility model relates to the field of single-bar stamping machine technology, and more specifically, to a single-bar multi-station auxiliary feeding device. Background Technology

[0002] A single-rod stamping machine is a main structure in stamping equipment that uses a single connecting rod as the core transmission component to realize the stamping action. Specifically, a connecting rod connects the crank (or eccentric wheel) and the slider, converting the rotational power of the motor into the reciprocating motion of the slider, thereby driving the die to stamp the workpiece. It is a commonly used piece of equipment for small and medium-sized stamping processes.

[0003] A search revealed that Chinese Patent No. CN215587691U discloses a receiving device for a multi-station stamping equipment for aluminized plates. This utility model has a driving mechanism on the support plate. Under the action of the driving mechanism, the limiting plate can be driven to slide along the slide groove. In this way, the aluminized plate placed on the support plate can be locked in place by the cooperation of the two limiting plates to prevent it from accidentally tipping over.

[0004] When using the above-mentioned stamping equipment, the workpiece is placed on the platform of the stamping machine, and then the workpiece is processed by the stamping machine. However, it is inconvenient to assist in feeding the workpiece. After each processing is completed, the workpiece needs to be manually removed from the platform and a new workpiece needs to be placed. The whole process requires waiting for the stamping machine to complete a work cycle. The long-term repetitive action of picking up and placing workpieces will make the operator feel tired.

[0009] Furthermore, both ends of the slide rod are fixedly connected to the support frame, and the rear side of the slide frame is movably sleeved on the slide rod.

[0010] As can be seen, in the above technical solution, the slide bar restricts the rotation of the sliding frame.

[0011] Furthermore, the two opposing sides of the two frame frames are fixedly connected to the sliding frame, the opposing ends of the two hydraulic cylinders are fixedly connected to the two extrusion plates respectively, and the opposing ends of the two hydraulic cylinders are fixedly connected to the two frame frames respectively.

[0012] Furthermore, the opposite sides of the two gaskets are respectively fixedly connected to two extrusion plates.

[0014] Furthermore, multiple mounting holes are provided on both the support frame and the side plate.

[0015] As can be seen, in the above technical solution, bolts are inserted into multiple mounting holes to install and fix the support frame and side plate, and the support frame is located on one side of the stamping machine.

[0016] The technical effects and advantages of this utility model are as follows:

[0017] 1. This utility model uses a robotic arm to adjust the position of an electric clamp, which then grips the workpiece. A conveyor belt transports the workpiece, and the same applies to workpieces at different workstations.

The operation is simple, and it can assist in feeding at multiple workstations, effectively reducing the labor intensity of workers.

[0018] 2. This utility model uses the extension of piston rods on two hydraulic cylinders to drive two extrusion plates and two gaskets to move towards each other. The two extrusion plates and two gaskets extrude and fix the workpiece. The stepper motor drives the workpiece to move horizontally and place the workpiece on the platform of the stamping machine. After the workpiece is processed, the stepper motor drives the workpiece away from the stamping machine. The structure is simple and easy to use. Attached Figure Description

[0026] The following specific embodiments illustrate the implementation of this utility model.

[0027] Refer to the instruction manual appendix Figure 1-5 This embodiment of a single-bar multi-station auxiliary feeding device includes a support frame 1 and a conveyor belt 2. The conveyor belt 2 is fixedly installed at the top center of the support frame 1. A side plate 3 is fixedly connected to the bottom edge of one side of the support frame 1. A robot arm 4 is fixedly installed at the top of the side plate 3. An electric clamp 5 is fixedly installed at one end of the robot arm 4 and is located at the top of the conveyor belt 2. A positioning component is provided between the robot arm 4 and the support frame 1. The positioning component includes a laser emitter 8, a vertical plate 9, and a laser receiver 10. A mounting frame 6 is provided on the outside of the conveyor belt 2, and the bottom end of the mounting frame 6 is fixedly connected to the support frame 1. A feeding component 7 is provided on the mounting frame 6. The feeding component 7 includes a stepper motor 701, a lead screw 702, a slide bar 703, a sliding frame 704, two side frames 705, two hydraulic cylinders 706, two extrusion plates 707, and two gaskets 708.

[0028] Furthermore, the laser emitter 8 is fixedly installed on one side of the robotic arm 4, and the laser emitter 8 is located on one side of the laser receiver 10. The laser receiver 10 is fixedly installed on one side of the upright plate 9, and the upright plate 9 is fixedly installed at the bottom of the support frame 1.

[0029] Furthermore, the stepper motor 701 is fixedly mounted on one side of the mounting bracket 6, and the output shaft end of the stepper motor 701 is fixedly connected to the lead screw 702. Both ends of the lead screw 702 are movably connected to the mounting bracket 6 through bearings, and the outer side of the lead screw 702 is threadedly connected to the sliding frame 704. Both ends of the slide rod 703 are fixedly connected to the support frame 1, and the rear side of the sliding frame 704 is movably sleeved on the slide rod 703.

The opposing sides of the two gaskets 708 are fixedly connected to the two extrusion plates 707, respectively.

[0030] When the workpiece is inside the mounting bracket 6, two hydraulic cylinders 706 are simultaneously activated. The piston rods on the two hydraulic cylinders 706 extend, causing the two extrusion plates 707 and two gaskets 708 to move towards each other. The two extrusion plates 707 and two gaskets 708 extrude and fix the workpiece, and the gaskets 708 can prevent the extrusion plates 707 from rigidly contacting the workpiece and causing wear.

Since the lead screw 702 is threadedly connected to the sliding frame 704, and the slide rod 703 restricts the rotation of the sliding frame 704, the lead screw 702 can drive the sliding frame 704 to move horizontally, thereby driving the workpiece to move horizontally and placing the workpiece on the platform of the stamping machine. After the workpiece is processed, the stepper motor 701 drives the workpiece away from the stamping machine. The structure is simple and easy to use.

[0031] Furthermore, multiple mounting holes are provided on both the support frame 1 and the side plate 3.

[0032] The usage method of this embodiment is as follows:

It is worth noting that the stamping machine is a single-rod stamping machine. The robot arm 4 is started, and the robot arm 4 adjusts the position of the electric clamp 5 so that the electric clamp 5 is located at the workstation. The electric clamp 5 is started, and the electric clamp 5 clamps the workpiece and places it on the conveyor belt 2. The conveyor belt 2 is started, and the conveyor belt 2 transports the workpiece. Similarly, workpieces at different workstations are transported. When the robot arm 4 rotates, the laser emitter 8 rotates with the robot arm 4. The laser emitter 8 is started, and the laser emitter 8 emits laser light. When the laser receiver 10 receives the laser light emitted by the laser emitter 8, it indicates that the electric clamp 5 is located directly above the conveyor belt 2, positioning the workpiece. The operation is simple, and it can assist in feeding at multiple workstations, effectively reducing the labor intensity of the workers.
