Description

Technical Field

[0001] The utility model relates to the technical field of stamping blanking, in particular to a positioning device for a stamping blanking machine. Background Art

[0002] Stamping is a forming method that uses a press and a die to apply external force to plates, strips, pipes and profiles to cause them to undergo plastic deformation or separation, thereby obtaining a workpiece (stamping part) of the desired shape and size.

[0003] In existing stamping presses, the feeding method primarily relies on a pulling mechanism. However, given the typically large mass and smooth surface of sheet metal, this pulling method can easily cause slight relative slippage between the strip and the pulling mechanism during operation. This slight slippage further causes the sheet metal to shift, leading to unstable stamping positions and increasing the risk of defective products. Furthermore, these defective products are visually similar to qualified products, making them difficult to distinguish using conventional methods, significantly impacting overall production quality and efficiency.

[0004] To address these issues, researchers have developed an innovative positioning device for blanking metal sheets. This device is designed to stably secure the metal sheet, preventing it from shifting or sliding during the stamping process. This ensures accurate stamping positioning, thereby improving product quality and efficiency. Utility Model Content

[0005] The purpose of the present utility model is to provide a positioning device for a punching blanking machine to solve the problems raised in the above background technology.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] A positioning device for a stamping blanking machine comprises a conveyor frame and a conveyor belt; a stamping frame is fixedly connected to the conveyor frame, a stamping component is fixedly connected to the stamping frame, and the stamping component is used to stamp the workpiece; the middle part of the conveyor belt is concave, and the concave part is a stamping groove, and a positioning component is provided above the stamping groove, and the positioning component is fixedly connected to the conveyor frame, and the positioning component is used to position the workpiece and can serve as a bottom plate to cooperate with the stamping component for stamping; a rotating shaft is rotatably connected to the stamping frame, one end of the rotating shaft is fixedly connected to a first motor, and a push plate is fixedly connected to the rotating shaft, and the push plate is an L-shaped structure.

[0008] When stamping a metal sheet, the sheet is placed on the conveyor belt on the conveyor rack. The sheet is then transported to the stamping slot. The stamping slot is equipped with a positioning component. The metal sheet falls onto the positioning component under the action of the conveyor belt. The positioning component is then activated to position and tighten the metal sheet. The stamping component is then activated to stamp the metal sheet. After stamping is completed, the first motor is activated, which drives the push plate to rotate, thereby pushing the metal sheet out of the stamping slot.

[0009] A further improvement of the technical solution of the present utility model is that: the stamping frame includes a base frame and a cross frame, the cross frame is a square tube type, and a discharge port is provided on the side of the cross frame that contacts the conveyor belt, and the discharge port is close to the stamping groove; a discharge plate is provided under the positioning component, the discharge plate is fixedly connected to the cross frame, and one end of the discharge plate extends into the discharge port.

[0010] By adopting the above technical solution, a discharge port and a discharge plate are set up, and the waste material punched by the stamping component will fall from the positioning component, and the waste material will then enter the horizontal frame through the discharge plate, thereby realizing the recycling of waste material, which is convenient and fast.

[0011] A further improvement of the technical solution of the present invention is that the discharge plate is arranged obliquely, and the bottom end of the inclined surface of the discharge plate is close to the discharge port.

[0012] The above technical solution is adopted. In this solution, the discharge plate is set to be inclined. After the waste falls from the positioning component to the discharge plate, under the action of gravity, the waste will slide along the surface of the positioning component into the horizontal frame to prevent the waste from being blocked on the discharge plate.

[0013] A further improvement of the technical solution of the present invention is that a push plate is slidably connected in the horizontal frame, and a push rod is fixedly connected to the push plate.

[0014] The above technical solution is adopted. In this solution, a push plate is set. When too much waste accumulates in the horizontal frame, the push rod is pulled, and the push plate slides inside the horizontal rod and then brings out the waste. It is convenient and practical and prevents the waste from clogging the inside of the horizontal tube.

[0015] A further improvement of the technical solution of the present utility model is that: the positioning component includes a stamping plate, which is fixedly connected to the stamping frame; a stamping hole is provided on the stamping plate; a plurality of slide rails are fixedly connected to the stamping plate, and a slider is slidably connected to the slide rail, and a moving block is fixedly connected to the slider; a fixed plate is provided above the moving block on both sides of the feed port and the discharge port, and the fixed plate and the moving block on the same side of the feed port and the discharge port are fixedly connected; a connecting block is fixedly connected at the center position of the stamping plate, and connecting heads are provided at both ends of the connecting block and the fixed plates on both sides, and the connecting block and the fixed plates on both sides are connected by a connecting rod; one side of the connecting block is fixedly connected to the cylinder, and the movable end of the cylinder is fixedly connected to one of the fixed plates on one side; the other end of the fixed plate is rotatably connected to a positioning foot, and the positioning foot is rotatably connected to a positioning wheel.

[0016] The above technical solution is adopted. In this solution, when the plate falls onto the stamping plate, the cylinder is started, and the cylinder drives the fixed plate on one side to move toward the connecting block, so that the slider moves toward the connecting block. The connecting block and the fixed plates on both sides are connected by connecting rods, so the moving blocks on both sides move toward each other at the same time to clamp the plate. At the same time, the plate is straightened with the cooperation of the positioning wheels and positioning feet.

[0017] A further improvement of the technical solution of the present utility model is that: a limiting rod is fixedly connected to the stamping plate along the moving direction of the slider.

[0018] By adopting the above technical solution, after the plate slides onto the stamping plate, a limiting rod is provided to perform preliminary limiting correction on the plate, which facilitates subsequent positioning.

[0019] A further improvement of the technical solution of the present invention is that both ends of the discharge plate are provided with discharge ports.

[0020] The above technical solution is adopted, in which discharge ports are provided at both ends of the discharge plate, thereby increasing the discharge speed of the waste and preventing the waste from accumulating on the discharge plate.

[0021] Due to the adoption of the above technical solution, the present invention has achieved the following technical advancements compared to the prior art:

[0023] 2. The utility model provides a positioning device for a stamping blanking machine. When the cylinder is started, the cylinder drives the fixed plate on one side to move toward the connecting block, so that the slider moves toward the connecting block. The connecting block and the fixed plates on both sides are connected by a connecting rod, so the moving blocks on both sides move toward each other at the same time to clamp the plate. At the same time, the plate is straightened with the cooperation of the positioning wheel and the positioning foot.

The connecting block 16 is connected to the fixed plates 15 on both sides by a connecting rod, so the moving blocks 14 on both sides move toward each other at the same time to clamp the sheet. At the same time, the sheet is straightened with the cooperation of the positioning wheel 19 and the positioning foot 18, and then the stamping component is started to stamp the metal sheet through the stamping component; after the stamping is completed, the first motor 5 is started, and the first motor 5 drives the push plate 6 to rotate, thereby pushing the metal sheet out of the stamping groove 4; the waste stamped by the stamping component will fall from the positioning component, and the waste will then enter the cross frame 8 through the discharge plate 10, thereby realizing the recycling of waste.
