Detailed Implementation

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0017] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0018] like Figure 1 As shown, the present invention provides a feeding device for a stamping forming machine, including a stamping machine 1. The stamping machine 1 is an existing device, including a lower die base, and an oil cylinder is connected to the upper side of the lower die base through a frame. A stamping head is connected to the lower side of the piston rod of the oil cylinder.

[0019] A conveyor platform 2 is connected to one side of the stamping machine 1. The conveyor platform 2 is set to correspond to the lower die base. The material plate can be conveyed to the lower die base by the conveyor platform, and then the stamping head stamps the material plate.

[0020] The conveying platform 2 includes a flat plate, with support legs 2.1 welded to the lower side of the flat plate. A chute for guiding the movement of the material plate is provided on the upper side of the flat plate. The chute is a rectangular groove, and the width of the chute is equal to the width of the material plate, while the depth of the chute is less than the thickness of the material plate.

[0021] Two support plates are welded to the feeding side of the conveying platform 2. Material boxes 9 are welded to the upper side of the two support plates. A feed inlet is provided on the upper side of the material box 9, and a discharge outlet is provided on the lower side of the material box 9. A stack of material plates is put into the material box through the feed inlet and output from the discharge outlet by gravity. The gap between the material box 9 and the conveying platform 2 can only be filled by one material plate. A pusher 10 is also connected to one side of the conveying platform 2. The pusher 10 is used to push the material plates output from the material box 9.

[0022] The pusher 10 includes a hydraulic cylinder 101, which is fixed to one side of the conveying platform 2 by bolts. A vertical plate 102 is connected to the piston rod of the hydraulic cylinder 101, and a push plate 103 is connected to the vertical plate 102. The push plate 103 is an L-shaped plate. When the push plate 103 pushes the bottom material plate, it can also block the lower discharge port of the material box 9 to prevent the material plate that is about to fall out of the material box 9 from rubbing against the piston plate of the hydraulic cylinder 101.

[0023] A guide hole is provided on the vertical plate 102, and a guide rod 104 is inserted into the guide hole. The guide rod 104 is welded to one side of the conveying platform 2. The guide rod 104 makes the push plate 103 more stable when pushing the material plate.

[0024] like Figure 3 As shown, a support 3 is connected to the conveying platform 2. The support 3 includes a top plate 3.1, and four support rods 3.2 are welded to the lower side of the top plate 3.1. The lower sides of the support rods 3.2 are welded to the conveying platform 2. A sliding groove 3.3 is provided on the lower side of the top plate 3.1, and a sliding plate 3.4 is slidably connected in the sliding groove 3.3. A drive device 11 is connected to the top plate 3.1. The drive device 11 is used to drive the sliding plate 3.4 to move. The drive device 11 includes a motor, which is fixed by bolts. The screw 111 is fixed on the top plate 3.1 and connected to the output shaft of the motor. The screw 111 has a threaded drive moving plate 112. The moving plate 112 has a threaded through hole and the screw 111 is threadedly connected in the threaded through hole. The top plate 3.1 has a through groove 3.5. The moving plate 112 passes through the through groove 3.5 and is welded to the sliding plate 3.4. The motor drives the screw 111 to rotate, and the screw 111 drives the moving plate 112. The moving plate 112 drives the sliding plate 3.4 to move.

[0025] A mounting plate 4 is welded to the lower side of the sliding plate 3.4, and a drive component 5 is connected to the lower side of the mounting plate 4. The drive component 5 can be a hydraulic cylinder, a pneumatic cylinder, or an electric push rod. In this embodiment, an electric push rod is preferred. The electric push rod is fixed to the lower side of the mounting plate 4 by bolts. A feeding component 6 is connected to the lower side of the piston rod of the electric push rod. The feeding component 6 is set on the upper side of the conveying platform 2.

[0026] A guide member 8 is connected between the mounting plate 4 and the feeding member 6. In this embodiment, there are two guide members 8. The guide member 8 includes a guide sleeve and a guide slide rod. The guide sleeve is welded to the lower side of the mounting plate 4, and the guide slide rod is welded to the upper side of the feeding member 6. The sliding of the guide slide rod in the guide sleeve makes the feeding member 6 more stable when moving up and down.

[0027] like Figure 2 As shown, the feeding component 6 includes a feeding plate 7, on which a row of first through slots 7.1 and a second through slot 7.2 are provided. The second through slot 7.2 is close to the stamping machine 1. Both the first through slot 7.1 and the second through slot 7.2 are used to fit the material plate, thereby driving the material plate to move. The lower openings of the first through slot 7.1 and the second through slot 7.2 are chamfered to facilitate the fitting of the material plate. The material plate is driven to the stamping machine 1 for stamping through the second through slot 7.2.

[0028] A cover 7.3 is welded to the upper side of each first through groove 7.1. Each cover 7.3 has a through hole, and a sliding rod 7.4 is inserted into each through hole. A limiting plate 7.5 is connected to the upper end of each sliding rod 7.4, and a pressure block 7.6 is connected to the lower end of each sliding rod 7.4. A spring 7.7 is sleeved on each sliding rod 7.4. The spring 7.7 is located between the pressure block 7.6 and the cover 7.3. The elastic force of the spring 7.7 drives the pressure block 7.6 to press the material plate tightly, preventing the material plate from moving when the first through groove 7.1 is disengaged, which would cause the first through groove 7.1 to fail to accurately fit the material plate during the next feeding.

[0029] When feeding the stamping press, this device first places a stack of plates into the material box 9. Under the action of gravity, the bottom plate falls onto the conveying platform 2. Then, the pusher 10 is activated to push the plate out from the bottom of the material box 9. The pusher 10 then returns to its original position, and the upper plate falls out next. After the pushed plate reaches the predetermined position, the drive device 11 is activated to drive the feeding plate 7 to move backward, so that the first through groove 7.1 closest to the material box 9 moves above the pushed plate. Then, the drive device 5 is activated to drive the feeding plate 7 to move downward so that the first through groove 7.1 fits the plate. Then, the drive device 11 drives the feeding plate 7 to move forward. Finally, the plate is conveyed to the lower die base of the stamping press 1 by the second through groove 7.2. After the stamping is completed, the drive device 11 and the drive device 5 drive the feeding plate 7 to feed again. During the second feeding, the feeding plate 7 pushes the first stamped plate forward and slides down the guide plate 1.1 into the collection basket.
