An inlet is provided above the discharging box, and an outlet is provided below the discharging box. A first clockwork spring is arranged between the lower partition board and the discharging box. The movement of the upper partition board closes the inlet above the discharging box, preventing the materials inside the storage bin from entering the inside of the discharging box, realizing the quantitative discharge of materials, avoiding excessive materials being discharged, resulting in the formed components not meeting the required standards, and reducing the subsequent maintenance costs.

[0007] According to the above technical solution, a first chute is provided below the feeding box, a baffle is slidably installed inside the first chute, a fixed block is fixedly installed above the workbench, and a second clockwork spring is arranged between the baffle and the first chute. The baffle moves to contact the fixed block and moves under its action to open the outlet of the feeding box, enabling the materials to be discharged, effectively preventing the materials from leaking from the gap at the connection when the feeding box moves, resulting in less materials than the standard and the stamping finished products not meeting the standard.

[0008] According to the above technical solution, the adsorption device includes a fixed frame, a sliding plate, a pressure rod, an L-shaped plate and an adsorption pipe. The output end of the stamping machine drives the stamping plate to move downward. The downward movement of the stamping plate contacts and squeezes the pressure rod to move downward, and the downward movement of the pressure rod drives the sliding plate to move downward. The fixed frame is fixedly installed above the workbench, the sliding plate is slidably installed inside the fixed frame, the pressure rod fixedly penetrates the upper and lower walls of the sliding plate, the L-shaped plate is slidably installed on the inner wall of the fixed frame, the adsorption pipe fixedly penetrates the inner and outer walls of the fixed frame, the sliding plate and the inner wall of the fixed frame are fixedly connected through an elastic telescopic rod, and a third clockwork spring is arranged between the L-shaped plate and the fixed frame. The downward movement of the L-shaped plate opens the inlet of the adsorption pipe, enabling the materials leaked during the stamping process to be adsorbed into the inside of the fixed frame through the adsorption pipe, avoiding the materials remaining on the workbench from affecting the stamping and feeding effects, and reducing the subsequent maintenance costs.

[0009] According to the above technical solution, a stop bar is fixedly installed on the surface of the adsorption tube, and a rotating plate is hinged on the surface of the adsorption tube. A fourth clockwork spring is arranged between the rotating plate and the adsorption tube. The rotating plate rotates and opens the inlet under the action of negative pressure and the stop bar, preventing the material from being adsorbed into the interior of the fixed frame without stamping, thereby affecting the stamping effect.

[0010] According to the above technical solution, it further includes a recovery device and a demoulding device. The recovery device includes a collection frame, a moving plate, a conduction rod, a stop block and a convex block. The sliding plate moves upward to contact and squeeze the conduction rod to move. The movement of the conduction rod drives the moving plate to move. A clamping groove is formed on the surface of the fixed frame. The collection frame is clamped with the fixed frame through the clamping groove. The moving plate slides through the inner and outer walls of the fixed frame. The conduction rod is fixedly installed on the surface of the moving plate. The stop block is fixedly installed on the inner wall of the fixed frame. The convex block is fixedly installed above the sliding plate. The upper part of the sliding plate is provided with a first inclined surface. The end of the conduction rod close to the sliding plate is provided with a second inclined surface. A fifth clockwork spring is arranged between the moving plate and the fixed frame. At the same time, the conduction rod moves to contact the convex block and generates vibration, improving the effect of material collection. The conduction rod is limited by the stop block to prevent the moving plate from moving under negative pressure, thereby breaking the negative pressure state, avoiding waste of raw materials and reducing the stamping cost.

[0011] According to the above technical solution, a receiving rod is slidably installed above the fixed frame, and a receiving block is slidably installed above the fixed frame. A receiving strip is fixedly installed on the surface of the receiving block. A second chute is formed on the surface of the receiving rod. A sixth clockwork spring is arranged between the receiving rod and the fixed frame. One end of the receiving block close to the collection frame is provided with an arc surface. The reset of the receiving block drives the receiving strip to move. The movement of the receiving strip drives the receiving rod to move. The movement of the receiving rod limits the moving plate, avoiding waste of materials during the process of replacing the collection frame.

[0012] According to the above technical solution, the demoulding device includes a demoulding plate, a moving block, a lifting rod, a moving rod and an inclined rod. The sliding plate moves upward to reset under the action of the elastic telescopic rod. The upward movement of the sliding plate drives the pressing rod to move upward. The upward movement of the pressing rod drives the inclined rod to move. A pressing groove is formed on the surface of the workbench. The demoulding plate is slidably installed inside the pressing groove. The moving block is slidably installed inside the pressing groove. The lifting rod is fixedly installed above the moving block. The moving rod is slidably installed below the workbench. The inclined rod is hinged on the surface of the moving rod. The end of the inclined rod far from the moving rod is hinged to the pressing rod. A third chute is formed on the surface of the moving block. The inner wall of the third chute is provided with a third inclined surface. The upward movement of the lifting rod contacts and drives the demoulding plate to move upward. The upward movement of the demoulding plate pushes out the raw material formed by stamping and pushes it out of the workbench under the action of the feeding box, reducing the working intensity of workers.

[0013] According to the above technical solution, a block is fixedly installed inside the pressing groove, a clockwork spring five is arranged between the moving rod and the workbench, and a clockwork spring seven is arranged between the moving block and the pressing groove. When the stamping plate moves downward to stamp the material, the stamping plate moves downward to drive the stripping plate to move downward, and the stripping plate is limited by the downward movement of the block, thereby improving the efficiency of stamping and reducing the subsequent maintenance cost.

[0014] The present invention provides a stamping device for powder metallurgy, which has the following beneficial effects: (1) In the powder metallurgy stamping equipment, when feeding, the output end of the hydraulic press drives the feed box and the connecting pipe to contact and squeeze the lower partition to move through the push rod. The lower partition moves to open the discharge port so that the material inside the discharge box is discharged. At the same time, the upper partition is driven by the connecting rod to close the feed port, thereby achieving quantitative discharge of the material, avoiding excessive material being discharged, resulting in the original parts formed by the stamping not meeting the required standards, and reducing subsequent maintenance costs. At the same time, when discharging, the feed box drives the baffle to contact the fixed plate and discharge the material under its action, further avoiding the material from leaking out from the gap at the connection when the feed box moves, resulting in less material than the standard and the stamped product not meeting the standard.

[0015] (2) In the powder metallurgy stamping equipment, during stamping, the stamping plate moves downward to squeeze the air inside the fixed frame through the pressure rod and the sliding plate, so that the space above the sliding plate becomes a negative pressure state. The sliding plate continues to move downward to drive the L-shaped plate to move and open the entrance of the adsorption tube. The material leaked during the stamping process is adsorbed into the interior of the fixed frame through the negative pressure, so that the material remaining on the workbench does not affect the stamping and feeding effects, thereby reducing the subsequent maintenance costs. At the same time, the rotating plate rotates under the action of negative pressure to open the inlet, so as to avoid the material being adsorbed when there is no stamping and thus affecting the stamping effect.

[0016] (3) In the stamping equipment for powder metallurgy, the sliding plate is reset and contacted under the action of the elastic telescopic rod and drives the conductive rod and the movable plate to move. The movable plate moves to open the entrance of the collection frame and discharge the raw materials adsorbed in the fixed frame into the interior of the collection frame. The conductive rod and the movable plate can avoid opening the entrance of the collection frame under negative pressure under the action of the block and the protrusion, and further improve the recycling effect, avoid the waste of raw materials, and reduce the cost of stamping. At the same time, when the collection frame is full and needs to be replaced, the collection frame moves to release the limit on the receiving block, so that the receiving rod is reset to achieve the limit on the movable plate, avoiding the waste of materials in the process of replacing the collection frame.

[0017] (4) In the powder metallurgy stamping equipment, after stamping, the pressing rod is reset and the lifting rod and the stripper plate are driven to move upward through the inclined rod and the moving rod. The stripper plate moves upward to push the stamped original part out of the pressing groove and pushes it out of the workbench under the action of the feed box, thereby reducing the work intensity of the workers. At the same time, the block inside the pressing groove can effectively prevent the stripper plate from excessively squeezing the lifting rod and the moving block downward during the stamping process, thereby improving the stamping efficiency and reducing the subsequent maintenance cost.

The movement of the upper partition 47 closes the inlet above the discharging box 45, preventing the materials inside the storage bin 41 from entering the inside of the discharging box 45, realizing the quantitative discharge of the materials, avoiding that too many materials are discharged, resulting in the components formed by stamping not meeting the required standards, and reducing the subsequent maintenance costs.

[0022] A first chute is provided below the feeding box 43, and a baffle 49 is slidably installed inside the first chute. A fixed block 410 is fixedly installed above the workbench 1. A second clockwork spring is arranged between the baffle 49 and the first chute. The baffle 49 moves to contact the fixed block 410 and moves under its action to open the outlet of the feeding box 43, so that the materials are discharged, effectively avoiding the materials leaking from the gap at the connection when the feeding box 43 moves, resulting in the materials being less than the standard and the stamping finished products not meeting the standard.

[0023] The adsorption device includes a fixed frame 51, a sliding plate 52, a pressure rod 53, an L-shaped plate 54, and an adsorption tube 55. The output end of the stamping machine drives the stamping plate 2 to move downward. When the stamping plate 2 moves downward, it contacts and presses the pressure rod 53 to move downward. The downward movement of the pressure rod 53 drives the sliding plate 52 to move downward. The fixed frame 51 is fixedly installed above the workbench 1. The sliding plate 52 is slidably installed inside the fixed frame 51. The pressure rod 53 fixedly penetrates the upper and lower walls of the sliding plate 52. The L-shaped plate 54 is slidably installed on the inner wall of the fixed frame 51. The adsorption tube 55 fixedly penetrates the inner and outer walls of the fixed frame 51. The sliding plate 52 is fixedly connected to the inner wall of the fixed frame 51 through an elastic telescopic rod. A third clockwork spring is provided between the L-shaped plate 54 and the fixed frame 51. The downward movement of the L-shaped plate 54 opens the inlet of the adsorption tube 55, so that the material leaked during the stamping process is adsorbed into the fixed frame 51 through the adsorption tube 55, avoiding the material remaining on the workbench 1 from affecting the stamping and feeding effects and reducing the subsequent maintenance cost.

[0024] A stop rod 56 is fixedly installed on the surface of the adsorption tube 55. A rotating plate 57 is hinged on the surface of the adsorption tube 55. A fourth clockwork spring is provided between the rotating plate 57 and the adsorption tube 55. The rotating plate 57 rotates and opens the inlet under the action of negative pressure and the stop rod 56, avoiding the material being adsorbed into the fixed frame 51 when there is no stamping, thus affecting the stamping effect.

[0025] When this embodiment works, the hydraulic machine 3 is started. The output end of the hydraulic machine 3 drives the push rod 42 to move. The movement of the push rod 42 drives the feed box 43 to move. The movement of the feed box 43 drives the connecting pipe 44 to move. The movement of the connecting pipe 44 contacts and drives the lower partition plate 46 to move. The movement of the lower partition plate 46 opens the discharge port below the discharge box 45, so that the material inside the discharge box 45 is discharged into the feed box 43. At the same time, the movement of the lower partition plate 46 drives the connecting rod 48 to move. The movement of the connecting rod 48 drives the upper partition plate 47 to move. The movement of the upper partition plate 47 closes the feed port above the discharge box 45, avoiding the material inside the storage box 41 from entering the discharge box 45, realizing the quantitative discharge of the material, avoiding too much material being discharged, resulting in the components formed by stamping not meeting the required standards, and reducing the subsequent maintenance cost. At the same time, the movement of the feed box 43 drives the baffle 49 to move. The movement of the baffle 49 contacts the fixed block 410 and moves under its action to open the outlet of the feed box 43, so that the material is discharged, effectively avoiding the material leaking from the gap at the connection when the feed box 43 moves, resulting in less material than the standard and the stamping finished product not meeting the standard.

[0026] During stamping, the output end of the stamping machine drives the stamping plate 2 to move downward. The stamping plate 2 moves downward to contact and squeeze the pressure rod 53 to move downward. The downward movement of the pressure rod 53 drives the sliding plate 52 to move downward. The downward movement of the sliding plate 52 squeezes the air inside the fixed frame 51, making the area above the sliding plate 52 in a negative pressure state. The sliding plate 52 continues to move downward to contact and drive the L-shaped plate 54 to move downward. The downward movement of the L-shaped plate 54 opens the inlet of the adsorption tube 55, so that the materials leaked during the stamping process are adsorbed into the interior of the fixed frame 51 through the adsorption tube 55, avoiding the materials remaining on the workbench 1 from affecting the stamping and feeding effects, reducing the subsequent maintenance costs. At the same time, the rotating plate 57 rotates and opens the inlet under the action of negative pressure and the stop rod 56, preventing the materials from being adsorbed into the interior of the fixed frame 51 when there is no stamping, thus affecting the stamping effect.

[0027] Please refer to Figures 1-7 Based on the above embodiments, in another embodiment of the present invention, a recycling device and a demolding device are further included. The recycling device includes a collection frame 61, a moving plate 62, a conduction rod 63, a stop block 64 and a convex block 65. The upward movement of the sliding plate 52 contacts and squeezes the conduction rod 63 to move. The movement of the conduction rod 63 drives the moving plate 62 to move. A card slot is provided on the surface of the fixed frame 51. The collection frame 61 is clamped with the fixed frame 51 through the card slot. The moving plate 62 slides through the inner and outer walls of the fixed frame 51. The conduction rod 63 is fixedly installed on the surface of the moving plate 62. The stop block 64 is fixedly installed on the inner wall of the fixed frame 51. The convex block 65 is fixedly installed above the sliding plate 52. The upper part of the sliding plate 52 is provided with an inclined plane one. One end of the conduction rod 63 close to the sliding plate 52 is provided with an inclined plane two. A torsion spring five is arranged between the moving plate 62 and the fixed frame 51. At the same time, the conduction rod 63 moves to contact the convex block 65 and generates vibration, improving the effect of material collection. The conduction rod 63 is limited by the stop block 64 to prevent the moving plate 62 from moving under negative pressure, thus breaking the negative pressure state, avoiding waste of raw materials and reducing the stamping cost.

[0028] A receiving rod 66 is slidably installed above the fixed frame 51. A receiving block 67 is slidably installed above the fixed frame 51. A receiving strip 68 is fixedly installed on the surface of the receiving block 67. A chute two is provided on the surface of the receiving rod 66. A torsion spring six is arranged between the receiving rod 66 and the fixed frame 51. One end of the receiving block 67 close to the collection frame 61 is provided with an arc surface. The reset of the receiving block 67 drives the receiving strip 68 to move. The movement of the receiving strip 68 drives the receiving rod 66 to move. The movement of the receiving rod 66 limits the moving plate 62, avoiding waste of materials during the process of replacing the collection frame 61.

[0029] The demolding device includes a demolding plate 71, a moving block 72, a lifting rod 73, a moving rod 74 and an inclined rod 75. The sliding plate 52 moves upward to reset under the action of the elastic telescopic rod. The upward movement of the sliding plate 52 drives the pressure rod 53 to move upward. The upward movement of the pressure rod 53 drives the inclined rod 75 to move. A pressure groove is formed on the surface of the workbench 1. The demolding plate 71 is slidably installed inside the pressure groove. The moving block 72 is slidably installed inside the pressure groove. The lifting rod 73 is fixedly installed above the moving block 72. The moving rod 74 is slidably installed below the workbench 1. The inclined rod 75 is hinged on the surface of the moving rod 74. One end of the inclined rod 75 away from the moving rod 74 is hinged to the pressure rod 53. A third chute is formed on the surface of the moving block 72. The inner wall of the third chute is set as an inclined plane three. The upward movement of the lifting rod 73 contacts and drives the demolding plate 71 to move upward. The upward movement of the demolding plate 71 pushes out the raw material formed by stamping and pushes it out of the workbench 1 under the action of the feeding box 43, reducing the working intensity of workers.

[0030] A square block 76 is fixedly installed inside the pressure groove. A fifth clockwork spring is arranged between the moving rod 74 and the workbench 1. A seventh clockwork spring is arranged between the moving block 72 and the pressure groove. When the stamping plate 2 moves downward to stamp the material, the downward movement of the stamping plate 2 drives the demolding plate 71 to move downward. The downward movement of the demolding plate 71 is limited by the square block 76, improving the stamping efficiency and reducing the subsequent maintenance cost.

[0031] When this embodiment works, when the sliding plate 52 resets under the action of the elastic telescopic rod, the sliding plate 52 moves upward to contact and squeeze the conduction rod 63 to move. The movement of the conduction rod 63 drives the moving plate 62 to move. The movement of the moving plate 62 opens the entrance of the collection box 61, so that the material collected above the sliding plate 52 enters the interior of the collection box 61 through the entrance. At the same time, the conduction rod 63 moves to contact the convex block 65 and generates vibration, improving the effect of material collection. The conduction rod 63 is limited by the stop block 64 to prevent the moving plate 62 from moving under negative pressure, thereby breaking the negative pressure state, avoiding waste of raw materials and reducing the stamping cost. When the material inside the collection box 61 is full and needs to be replaced, after the collection box 61 moves, the limit on the bearing block 67 is released. After the limit is released, the bearing block 67 resets to drive the bearing strip 68 to move. The movement of the bearing strip 68 drives the bearing rod 66 to move. The movement of the bearing rod 66 limits the moving plate 62 to avoid waste of materials during the process of replacing the collection box 61.

[0032] After stamping is completed, the sliding plate 52 moves upward for reset under the action of the elastic telescopic rod. The upward movement of the sliding plate 52 drives the pressure rod 53 to move upward. The upward movement of the pressure rod 53 drives the inclined rod 75 to move. The movement of the inclined rod 75 drives the moving rod 74 to move. The moving rod 74 moves to contact and squeeze the moving block 72 to move upward. The upward movement of the moving block 72 drives the lifting rod 73 to move upward. The upward movement of the lifting rod 73 contacts and drives the stripping plate 71 to move upward. The upward movement of the stripping plate 71 pushes out the raw material formed by stamping and is pushed out of the workbench 1 under the action of the feeding box 43, reducing the working intensity of workers. At the same time, when the stamping plate 2 moves downward to stamp the material during stamping, the downward movement of the stamping plate 2 drives the stripping plate 71 to move downward. The downward movement of the stripping plate 71 is limited under the action of the square block 76, improving the stamping efficiency and reducing the subsequent maintenance cost.
