[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4The present invention relates to a feeding device for a press machine, comprising a press machine body 1; a conveyor belt 11 is installed on one side of the press machine body 1; a support plate 12 is fixedly connected to one side of the press machine body 1; an electric push rod 13 is connected to the middle of the support plate 12; a slot 14 is opened in the middle of the support plate 12; one end of the electric push rod 13 is fixedly connected to a first slide post 15; a triangular plate 16 is fixedly connected to the bottom of the first slide post 15; a support table 17 is fixedly connected to the bottom of the support plate 12; a second slide post 18 is slidably connected to the middle of the support table 17; a baffle plate 19 is fixedly connected to the bottom of the second slide post 18; and a tension spring 111 is fixedly connected to the top of the second slide post 18; when working, the workpiece to be stamped is first placed on the conveyor belt 11, and the workpiece can be conveyed to the press machine body 1 under the operation of the conveyor belt 11, and at the same time, the electric push rod 13 is operated to drive the first slide post 15 to slide in the middle of the slot 14, and the sliding of the first slide post 15 will drive the triangular plate 16 to move, and the triangular plate 16 is in the middle of the slot 14. When the first slide post 15 and the triangle plate 16 are moved back, the tension spring 111 rebounds due to the lack of the constraint of the extrusion force, thereby driving the second slide post 18 and the baffle plate 19 to slide upward. At this time, the workpiece can continue to be transported to the press body 1. This step can limit the number of workpieces transmitted each time through the cooperation of the triangle plate 16 and the second slide post 18, thereby preventing multiple workpieces from arriving at the working area of ​​the press body 1 at the same time when the workpieces are not arranged neatly or when transmission slippage occurs, thereby increasing the risk of waste and defective products during processing, resulting in increased costs and affecting production efficiency.

[0025] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown, the top of the second slide post 18 is fixedly connected to the U-shaped plate 2; the middle of the U-shaped plate 2 is rotatably connected to the rotating shaft 21; the middle of the rotating shaft 21 is fixedly connected to the roller 22; the middle of the roller 22 is provided with a limiting groove 23; the bottom of the triangular plate 16 is fixedly connected to the guide rail 24; during operation, when the triangular plate 16 squeezes the second slide post 18 during movement, it will contact the roller 22 first, and at this time, the rollers 22 will generate friction with each other under the influence of the movement of the triangular plate 16, and then drive the rotating shaft 21 to rotate in the middle of the U-shaped plate 2 under the action of the friction force, and the limiting groove 23 is stuck in the guide rail 24, so the roller 22 is limited when rotating. The opening of the positioning groove 23 and the guide rail 24 will roll along the surface of the guide rail 24. This step can reduce the friction between the second slide post 18 and the triangular plate 16 through the action of the roller 22, thereby preventing the second slide post 18 from sliding difficultly due to excessive friction between the triangular plate 16 and the second slide post 18, thereby affecting the blocking effect of the baffle plate 19. The cooperation of the guide rail 24 and the limiting groove 23 can limit the rolling trajectory of the roller 22, thereby preventing the roller 22 from easily moving left and right due to uneven force when rolling, thereby causing the position of the second slide post 18 and the baffle plate 19 to change.

[0026] like Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 As shown, a hollow guide column 3 is fixedly connected to the middle of the support table 17; an arc-shaped slide groove 31 is provided in the middle of the hollow guide column 3; a plurality of sets of balls 32 are rotatably connected to the middle of the arc-shaped slide groove 31; during operation, when the second slide column 18 slides, it will slide with the middle of the hollow guide column 3, and the second slide column 18 will generate friction with the balls 32 during the sliding process. Under the action of friction, the balls 32 will roll in the middle of the arc-shaped slide groove 31. This step can reduce the friction between the second slide column 18 and the hollow guide column 3 during the sliding process through the provision of the balls 32, thereby preventing the second slide column 18 from sliding due to excessive friction, thereby affecting the normal sliding of the second slide column 18 and causing the baffle plate 19 to fall and get stuck.

[0027] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4As shown, two groups of rectangular plates 4 are fixed to the bottom of the support plate 12; rectangular grooves 41 are opened in the middle of the rectangular plates 4; two groups of limit plates 42 are fixed to the top of the triangular plate 16; during operation, when the triangular plate 16 moves, it will drive the limit plates 42 to move synchronously, and the movement of the limit plates 42 will slide along the rectangular grooves 41 at the rectangular plates 4. This step can limit the moving trajectory of the triangular plate 16 through the interaction between the limit plates 42 and the rectangular plates 4 and the rectangular grooves 41, thereby preventing the triangular plate 16 from easily shifting in position due to uneven force during movement, thereby affecting the normal driving of the baffle plate 19 to fall.

[0028] like Figure 1 、 Figure 2 As shown, slide bars 5 are fixed on both sides of the top of the first slide post 15; two sets of oblique grooves 51 are opened in the middle of the support plate 12; during operation, when the electric push rod 13 drives the first slide post 15 to move, the slide bar 5 will move with the movement of the first slide post 15, and the bottom of the slide bar 5 will slide along the oblique grooves 51 when moving. This step can limit the sliding trajectory of the first slide post 15 through the mutual cooperation of the slide bar 5 and the oblique grooves 51, thereby improving the position stability of the first slide post 15 when sliding.

[0029] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 As shown, multiple groups of brushes 6 are connected to the bottom of the baffle plate 19; during operation, when the baffle plate 19 moves up and down, it will drive the brushes 6 to move synchronously, and the workpiece at the conveyor belt 11 will produce friction with the brushes 6 during the lifting process. At this time, the brushes 6 can clean the surface of the workpiece. This step can improve the cleanliness of the workpiece surface by cleaning the workpiece through the brush 6, thereby preventing the situation where the workpiece is easily affected by oil or dust on the surface during stamping, thereby preventing the stamping accuracy from being affected.

[0030] like Figure 2 、 Figure 3 As shown, a rubber strip 7 is connected to one side of the baffle plate 19; during operation, when the baffle plate 19 blocks the transmission of the workpiece, the workpiece will rest against the rubber strip 7. At this time, the rubber strip 7 can reduce the friction and collision between the workpiece and the baffle plate 19. This step can protect the workpiece and the baffle plate 19 through the action of the rubber strip 7, thereby preventing the workpiece and the baffle plate 19 from being easily worn due to friction and collision, thereby affecting their service life.

[0031] Working principle: when working, first place the workpiece to be punched on the conveyor belt 11, and the workpiece can be conveyed to the press body 1 under the operation of the conveyor belt 11, and at the same time, the electric push rod 13 is operated to drive the first slide post 15 to slide in the middle of the slot 14, and the sliding of the first slide post 15 will drive the triangular plate 16 to move, and the bottom of the triangular plate 16 will squeeze the second slide post 18 during the displacement process. At this time, the second slide post 18 will drive the baffle plate 19 to slide downward under the influence of the extrusion, and the tension spring 111 will be compressed under the influence of the extrusion force until the baffle plate 19 moves to a certain position, which will block the workpiece at the conveyor belt 11, thereby preventing the workpiece from being transmitted to the press body 1. When the electric push rod 13 drives the first slide post 1 5 and the triangular plate 16 move back, the tension spring 111 rebounds due to the lack of the constraint of the extrusion force, thereby driving the second slide post 18 and the baffle plate 19 to slide upward. At this time, the workpiece can continue to be conveyed to the press body 1. This step can limit the number of workpieces conveyed each time through the cooperation of the triangular plate 16 and the second slide post 18, thereby preventing multiple workpieces from arriving at the working area of ​​the press body 1 at the same time when the workpieces are not arranged neatly or the conveying slips, thereby increasing the risk of waste and defective products in the processing process, resulting in increased costs and affecting production efficiency. During operation, when the triangular plate 16 squeezes the second slide post 18 during its movement, it will contact the roller 22 first. At this time, the roller 22 is on the triangular plate 1 6 under the influence of the movement, friction will be generated between them, and then the rotating shaft 21 will be driven to rotate in the middle of the U-shaped plate 2 under the action of the friction force, and the limiting groove 23 is stuck in the guide rail 24, so when the roller 22 rotates, it will roll along the surface of the guide rail 24 due to the opening of the limiting groove 23 and the guide rail 24. This step can reduce the friction between the second slide post 18 and the triangular plate 16 through the action of the roller 22, thereby preventing the second slide post 18 from sliding difficultly due to excessive friction between the triangular plate 16 and the second slide post 18, thereby affecting the blocking effect of the material blocking plate 19. The cooperation between the guide rail 24 and the limiting groove 23 can limit the rolling trajectory of the roller 22, thereby preventing the roller 22 from easily being The uneven force causes the left and right lateral movement, thereby causing the position of the second slide post 18 and the baffle plate 19 to change. During operation, when the second slide post 18 slides, it slides with the middle part of the hollow guide post 3, and the second slide post 18 generates friction with the ball 32 during the sliding process. Under the action of friction, the ball 32 rolls in the middle of the arc groove 31. This step can reduce the friction between the second slide post 18 and the hollow guide post 3 during the sliding process through the opening of the ball 32, thereby preventing the second slide post 18 from sliding difficultly due to excessive friction, thereby affecting the normal sliding of the second slide post 18 and causing the baffle plate 19 to fall and get stuck. During operation, when the triangular plate 16 moves, it drives the limit plate 42 to move synchronously.The movement of the limit plate 42 will slide along the rectangular slide groove 41 of the rectangular plate 4. This step can play the role of limiting the movement trajectory of the triangular plate 16 through the interaction between the limit plate 42, the rectangular plate 4 and the rectangular slide groove 41, thereby preventing the triangular plate 16 from easily deviating from its position due to uneven force when moving, thereby affecting the normal driving of the baffle plate 19 to fall. During operation, when the electric push rod 13 drives the first slide post 15 to move, the slide bar 5 will move with the movement of the first slide post 15, and the bottom of the slide bar 5 will slide along the oblique slide groove 51 when moving. This step can play the role of limiting the sliding trajectory of the first slide post 15 through the mutual cooperation of the slide bar 5 and the oblique slide groove 51, thereby improving the position stability of the first slide post 15 when sliding. During operation, when the baffle plate 19 When moving up and down, it will drive the brush 6 to move synchronously, and the workpiece at the conveyor belt 11 will rub against the brush 6 during the lifting process. At this time, the brush 6 can clean the surface of the workpiece. This step can improve the cleanliness of the workpiece surface through the brush 6 to clean the workpiece, thereby preventing the workpiece from being easily affected by oil or dust on the surface during stamping, thereby preventing the stamping accuracy from being affected. During operation, when the baffle plate 19 blocks the transmission of the workpiece, the workpiece will rest against the rubber strip 7. At this time, the rubber strip 7 can reduce the friction and collision between the workpiece and the baffle plate 19. This step can protect the workpiece and the baffle plate 19 through the action of the rubber strip 7, thereby preventing the workpiece and the baffle plate 19 from being easily worn due to friction and collision, thereby affecting their service life.
