Description

Technical Field

[0001] The invention provides a stamping device for aluminum alloy precision die forgings, and particularly relates to the technical field of stamping and die casting. Background Art

[0002] Aluminum alloy precision die forgings are aluminum alloy forgings with complex shapes and high precision forged on die forging equipment. The production process is to use a hydraulic device to bring the workpiece to be forged (such as a plate) into contact with the die surface, and use stamping to form the desired shape on the workpiece surface (such as a groove or hole on the plate surface). This process does not require cutting and processing and is widely used in the preparation of aluminum alloy plate workpieces.

[0003] The utility model with authorization announcement number CN217095209U discloses a cold stamping device for aluminum alloy plates. When the stamping device is in operation, the aluminum alloy plate is placed in the internal clamping groove of the clamping push plate and pushed. The clamping push plate cooperates with the fixed clamping plate to push the aluminum alloy plate to the specified position, and contacts and fixes it with the limit baffle, thereby limiting and fixing the aluminum alloy plate. Then, in conjunction with the cold stamping template above, it is convenient to perform precise and stable stamping operations on the aluminum alloy plate, which can effectively prevent the plate from offsetting and shaking during stamping.

[0004] The above-mentioned punching device still has the following defects in the process of punching aluminum alloy plates: when the punching device is in use, it only relies on the clamping push plate and the fixed clamping plate to position the two sides of the aluminum alloy plate, and the plate and the fixed clamping plate are supported by the plate clamping groove set, and as the pushing cylinder drives the clamping push plate and the fixed clamping plate and the aluminum alloy plate to be pushed horizontally, the stability of the single-point push of the cylinder is poor, which is easy to cause the plate to be offset during the pushing process, so when the plate moves to the position of the bearing bottom plate, that is, on the mold on the punching table in the prior art, it is easy to cause the relative position between the plate and the mold to deviate, thereby affecting the punching quality of the aluminum alloy plate. Moreover, the two sides of the aluminum alloy plate are placed horizontally in the plate clamping groove, resulting in a gap between the plate and the bearing bottom plate. Then, during punching, the contact part between the aluminum alloy plate and the plate clamping groove will be subjected to downward punching pressure, thereby causing the contact part between the plate and the plate clamping groove, that is, the two side edges of the aluminum alloy plate to be deformed, thereby affecting the final punching effect of the aluminum alloy plate.

DETAILED DESCRIPTION

[0021] The present invention will be further described below in conjunction with the embodiments.

[0022] Embodiments of the present invention are as follows: Embodiment 1: Figures 1 to 7 As shown, a stamping device for aluminum alloy precision die forgings includes a stamping table 1, a gantry 11 is fixedly arranged on one side of the upper surface of the stamping table 1, a hydraulic cylinder 12 is fixedly installed in the middle of the gantry 11, a movable die 13 is arranged on the telescopic end below the hydraulic cylinder 12, and a fixed die 14 is arranged on the upper surface of the stamping table 1 and at a position corresponding to the movable die 13. The above components are all main components of the existing stamping machine, and a controller is also arranged on the gantry 11. One side of the gantry 11 is set to be open.

[0023] An active feeding mechanism is provided on one side of the upper surface of the punching table 1 and close to the open part of the door frame 11. The active feeding mechanism includes two combination boxes 21 symmetrically arranged on both sides of the upper surface of the punching table 1. The two combination boxes 21 are respectively composed of an upper and a lower part, and the upper and lower parts are detachably connected. Specifically, the lower part of the two combination boxes 21 is fixed to the upper surface of the punching table 1. The inside of the two combination boxes 21 is rotatably connected with a lead screw 22, which is arranged inside the combination box 21, which can reduce the adhesion of external dust or debris and ensure the accuracy and stability of the transmission. The ends of the two lead screws 22 close to the door frame 11 pass through the combination box 21 and extend to the outside of the combination box 21. The two lead screws 22 are both sleeved with a sleeve block 23. The two sleeve blocks 23 and the corresponding lead screws 22 form a ball screw structure. The upper and lower parts of the two combination boxes 21 are threadedly connected by bolts and nuts. When in use, after separating the bolts and nuts, the upper part and the lower part of the combination box 21 can be manually separated, so as to facilitate the staff to perform corresponding maintenance on the lead screws 22 and the sleeve blocks 23 to ensure the stability of the transmission of the lead screws 22 and the sleeve blocks 23. The outer walls of both sides of the two combination boxes 21 are symmetrically provided with strip grooves 2101. The two sides of the two sleeves 23 pass through the corresponding strip grooves 2101 and are in sliding cooperation with the strip grooves 2101. The two sleeves 23 are fixedly connected with a T-shaped plate 24 on one side passing through the strip groove 2101. Two right-angle plates 25 are fixedly provided on the sides of the two T-shaped plates 24 close to each other. The four right-angle plates 25 are distributed in a rectangular shape, and the four right-angle plates 25 are provided with right-angle grooves. The four right-angle grooves on the four right-angle plates 25 are used to place the aluminum alloy sheet to be stamped. The upper surface of the stamping table 1 and the right below between the two T-shaped plates 24 are evenly connected and rotated with a plurality of array rods 251. The outer ring surfaces of the plurality of array rods 251 are all smooth surfaces. When the aluminum alloy sheet is placed in the right-angle grooves on the four right-angle plates 25, the bottom surface of the aluminum alloy sheet just contacts the outer ring surface of the array rods 251. After the four right-angle plates 25 are horizontally displaced to the final position in the direction close to the fixed mold 14, they are located just above the fixed mold 14, and at this position, the four right-angle plates 25 do not contact the outer wall of the fixed mold 14, that is, the width between two of the four right-angle plates 25 is greater than the width of the fixed mold 14, and the bottom groove surfaces of the right-angle grooves in the four right-angle plates 25 are flush with the upper surface of the fixed mold 14. Specifically, when an aluminum alloy plate is placed in the right-angle grooves on the four right-angle plates 25, and the four right-angle plates 25 move to just above the fixed mold 14, the bottom surface of the aluminum alloy plate fits exactly with the upper surface of the fixed mold 14.A partition 26 is fixedly arranged on the upper surface of the punching table 1 and on one side close to the door frame 11. One end of the two lead screws 22 located outside the corresponding combination box 21 passes through the partition 26 and extends to the outside of the partition 26. A servo motor 27 is fixedly installed on the upper surface of the punching table 1 and on one side close to the partition 26. The ends of the two lead screws 22 located outside the partition 26 are fixedly connected to synchronous wheels 28. A synchronous belt 29 is connected between the two synchronous wheels 28. The synchronous wheel 28 on the side close to the servo motor 27 is coaxially fixed with the output shaft of the servo motor 27. The servo motor 27 is controlled by the controller on the above-mentioned door frame 11. The above-mentioned partition 26 is arranged between the fixed mold 14 and the servo motor 27, the synchronous wheel 28, and the synchronous belt 29, which can prevent the debris from splashing onto the surfaces of the three during the stamping process and affecting the stability of the transmission.

[0024] Furthermore, if Figure 6 , Figure 7 As shown, fastening assemblies are symmetrically arranged on the two T-shaped plates 24, and the fastening assemblies include two abutment plates 241 movably inserted on the T-shaped plates 24, and side plates 242 are fixedly arranged on the two T-shaped plates 24 and at positions corresponding to the four abutment plates 241, and springs 243 are connected between the sides of the four abutment plates 241 that are away from each other and the corresponding side plates 242, and the sides of the four abutment plates 241 that are close to each other are provided with inclined surfaces and vertical surfaces, wherein the inclined surfaces are located above the vertical surfaces.

[0025] During use: the staff uses the position of the four right-angle plates 25 as a reference, and aligns the bottom four corners of the aluminum alloy plate (hereinafter referred to as the plate) to be processed with the positions of the four right-angle grooves, and then places the plate downward. As the plate is placed downward, the bottom four corners of the plate will be in contact with the inclined surface of the plate 241, and under the gravity of the aluminum alloy plate and the pressure of the staff placing the plate downward, the bottom four corners of the plate will continue to squeeze the inclined surface of the plate 241, so that the four plates 241 gradually move horizontally away from the plate, and the spring 243 is compressed in the process. When the plate is gradually placed downward, the bottom four corners of the plate are fitted with the bottom groove surface of the right-angle groove, and the bottom of the plate is just separated from the inclined surface of the plate 241, and then the vertical surfaces of the four plates 241 are pressed against the outer wall of the plate under the rebound force of the spring 243, and the placement of the plate is completed.

[0026] Therefore, through the cooperation of the four abutment plates 241 and the spring 243, after the staff places the aluminum alloy plate in the right-angle groove of the right-angle plate 25, the rebound force of the spring 243 causes the vertical surfaces of the four abutment plates 241 to press against the side walls of the plate, thereby stably clamping and fixing the plate, ensuring the stability of the plate placed in the vertical groove, ensuring that the plate will not be displaced during the subsequent pushing of the plate for stamping processing, and thus ensuring the forming quality of the aluminum alloy plate in the subsequent stamping processing.

[0027] Subsequently, the staff starts the servo motor 27 through the controller, causing the output shaft of the servo motor 27 to drive a synchronous wheel 28 to rotate, and the synchronous wheel 28 drives another synchronous wheel 28 to rotate synchronously through the synchronous belt 29, so that the servo motor 27 can drive the two lead screws 22 to rotate synchronously, and after the two lead screws 22 rotate synchronously, under the sliding cooperation between the strip groove 2101 and the sleeve block 23, the sleeve block 23 is caused to stably move horizontally along the trajectory of the strip groove 2101 toward the direction close to the fixed mold 14, thereby through the two sleeves The block 23 drives the two T-shaped plates 24, the four right-angle plates 25 and the plates horizontally placed in the four right-angle grooves to synchronously move horizontally until the plates are horizontally transferred to the top of the fixed mold 14, and then the servo motor 27 is turned off by the controller. After the servo motor 27 is turned off, its output shaft will not rotate freely, that is to say, when the plate moves to the final position, the lead screw 22 will not rotate, then the sleeve block 23 and the T-shaped plate 24, the right-angle plate 25 and the plate will not move horizontally, so as to avoid the plate being displaced after being sent to the top of the fixed mold 14 due to external interference.

[0028] Subsequently, the hydraulic cylinder 12 is started through the controller, and the telescopic end of the hydraulic cylinder 12 drives the movable die 13 to gradually move vertically downward, and finally punches the plate located on the upper surface of the fixed die 14. When the punching is completed, the servo motor 27 is started through the controller to cause the output shaft of the servo motor 27 to rotate in the opposite direction, thereby sending the punched plate out horizontally in the opposite direction, and the stamping process of the aluminum alloy plate is completed.

[0029] Therefore, the two lead screws 22 are driven to rotate synchronously through the servo motor 27, and the four right-angle plates 25 and the vertical grooves are cooperated to stably limit the aluminum alloy plate. The stable transmission effect of the ball screw structure can be used to stably transfer the plate to the stamping position for stamping processing, avoiding displacement between the plate and the mold. There is no gap between the plate and the mold, and no deformation of the edge of the plate will occur. While ensuring the stability of the plate, the hydraulic cylinder 12 is cooperated to provide hydraulic stamping pressure, and the aluminum alloy plate is stably stamped through the movable mold 13 and the fixed mold 14 to improve the stamping effect of the aluminum alloy plate.

[0030] At the same time, during the horizontal transfer of the above-mentioned plate, with the cooperation of multiple array rods 251 on the upper surface of the stamping table 1, the bottom of the plate can be supported during the conveying of the plate, and can rotate with the transfer of the plate, thereby further improving the stability of the plate during the transfer process and avoiding displacement of the plate and affecting the final stamping quality.

[0031] Embodiment 2: Figure 1 , Figures 8 to 10As shown, the aluminum alloy precision die forging stamping device further includes a follow-up processing mechanism disposed on the partition 26, the follow-up processing mechanism includes a linkage disk 31 rotatably connected to the side of the partition 26 close to the lead screw 22, the linkage disk 31 corresponds to the position of a lead screw 22, and specifically, the linkage disk 31 is located above the lead screw 22. A transmission component 32 is transmission-connected between the linkage disk 31 and the lead screw 22, and the transmission component 32 is composed of two pulleys and a belt transmission-connected between the two pulleys, wherein the upper pulley is coaxially fixed with the linkage disk 31, and the pulley is located on the side close to the partition 26, and the lower pulley is coaxially fixed with the end of the lead screw 22 located outside the assembly box 21, and the pulley is located between the partition 26 and the lead screw 22. A cam 33 is fixedly provided at an eccentric position on the surface of one side of the linkage disk 31 close to the screw 22, a negative pressure cylinder 34 is fixedly installed on the side of the partition plate 26 close to the linkage disk 31, a piston with a rod 35 is movably inserted inside the negative pressure cylinder 34, the piston with a rod 35 is composed of a rod body and a piston disk fixedly connected to the rod body, wherein one end of the rod body passes through the negative pressure cylinder 34 and extends to the outside of the negative pressure cylinder 34, the piston disk is located inside the negative pressure cylinder 34, and the end of the rod body of the piston with a rod 35 located outside the negative pressure cylinder 34 is fixedly connected with a grooved plate 36, the grooved plate 36 is slidably matched with the cam 33, the piston disk in the piston with a rod 35 and the negative pressure cylinder 34 form a piston cylinder structure, and the end of the negative pressure cylinder 34 away from the linkage disk 31 is connected with a T-shaped hard pipe 37. A one-way air inlet valve is installed at the portion where the T-shaped hard tube 37 is connected to the negative pressure cylinder 34, and suction frames 38 are provided at both upper and lower ends of the T-shaped hard tube 37 away from the negative pressure cylinder 34. The two suction frames 38 are flared on the sides close to the movable mold 13 and the fixed mold 14, and the flared portions of the two are respectively facing the movable mold 13 and the fixed mold 14. Specifically, the flared shape of the two suction frames 38 can enhance the suction effect, and the flared portion of the upper suction frame 38 faces the bottom surface of the movable mold 13 when in the initial position, and the flared portion of the lower suction frame 38 always faces the upper surface of the fixed mold 14, and the width of the flared portions of the two is greater than the width of the movable mold 13 and the fixed mold 14, so as to increase the coverage range when the flared portions of the two suction frames 38 generate negative pressure. A discharge pipe 39 is provided at the bottom of the negative pressure cylinder 34 away from the linkage disk 31, and a one-way air outlet valve is installed at the portion where the discharge pipe 39 is connected to the negative pressure cylinder 34. One end of the discharge pipe 39 away from the negative pressure cylinder 34 passes through the partition 26 and extends to the outside of the partition 26. One end of the discharge pipe 39 located outside the partition 26 is connected to a collection box 310. The collection box 310 consists of a fixed box and a moving box inserted into the fixed box, and both the fixed box and the moving box are provided with through holes connected to the discharge pipe 39. The fixed box in the collection box 310 is fixed to the side of the partition 26 away from the linkage disk 31, and both the fixed box and the moving box are made of transparent acrylic. When in use, the staff can regularly pull the moving box out of the fixed box horizontally to subsequently recycle the collected debris.

[0032] When in use: In the process of transferring the plate in the above-mentioned embodiment 1, as the lead screw 22 rotates through the transmission component 32, it will also drive the linkage disk 31 to rotate synchronously, and as the linkage disk 31 rotates, the cam 33 is driven to rotate synchronously, so that the cam 33 cooperates with the grooved plate 36 to cause the rod piston 35 to reciprocate horizontally in the negative pressure cylinder 34. When the piston disk in the rod piston 35 is horizontally displaced toward the linkage disk 31, the one-way air intake valve is opened, and negative pressure will be formed at the two suction frames 38 through the T-shaped hard pipe 37, and the two suction frames 38 are respectively facing the bottom surface of the movable mold 13 and the top surface of the fixed mold 14, so that the stamping debris on the surface of the movable mold 13 and the fixed mold 14 is automatically sucked into the negative pressure cylinder 34 by the negative pressure. As the piston disk gradually moves horizontally inside the negative pressure cylinder 34 in a direction away from the linkage disk 31, the one-way air inlet valve is closed and the one-way air outlet valve is opened, so that the debris sucked into the negative pressure cylinder 34 is sent to the collection box 310 through the discharge pipe 39 for real-time collection.

[0033] Therefore, by utilizing the negative pressure formed at the two suction frames 38, before each aluminum alloy sheet is stamped, the processing debris adhered to the surfaces of the movable die 13 and the fixed die 14 from the previous processing can be sucked out, thereby avoiding the stamping of the aluminum alloy sheet due to debris remaining on the surfaces of the movable die 13 and the fixed die 14, and avoiding the occurrence of defects on the surface of the aluminum alloy sheet after stamping, thereby improving the stamping quality of the aluminum alloy sheet.

[0034] In addition, after the processing debris on the surface of the movable mold 13 and the fixed mold 14 are sucked out by the two suction frames 38, they are automatically sent to the collection box 310 for unified collection and processing. Not only does it not require manual processing, but it also does not cause the debris to adhere to other components of the stamping device, thereby ensuring the overall cleanliness of the stamping device.

[0035] Embodiment 3: Figure 1 , Fig.11 , Fig.12As shown, the above-mentioned aluminum alloy precision die forging stamping device also includes a matching protection mechanism arranged on a sleeve block 23 near the door frame 11 side, the matching protection mechanism includes a reversing gear 41 rotatably connected to the door frame 11 near the combination box 21 side, the door frame 11 near the combination box 21 side surface is slidably connected with a door panel 42, specifically, the door frame 11 is provided with a slide groove for the door panel 42 to slide up and down, and the door panel 42 is made of polycarbonate hard transparent material, the transparent door panel 42 plays a protective role, and will not affect the staff to observe the stamping situation. A vertical rack 43 is fixedly connected to one side of the door panel 42 close to the reversing gear 41, and the vertical rack 43 meshes with the reversing gear 41. A sleeve block 23 is fixedly connected to one side outside the strip groove 2101 with a bending plate 44, and a horizontal rack 45 is fixedly connected to the upper end of the bending plate 44, and the horizontal rack 45 meshes with the reversing gear 41. Specifically, the reversing gear 41 is a cylindrical gear, and the teeth on its outer ring surface can mesh with the teeth on the horizontal rack 45 and the vertical rack 43 respectively, and the horizontal rack 45 and the vertical rack 43 are staggered with each other, that is, the two are not on the same horizontal line, that is, they will not conflict with each other when they are displaced, and the door frame 11 is provided with an external groove for the vertical rack 43, the bending plate 44, and the horizontal rack 45 to pass horizontally.

[0036] When in use: In the process of horizontally transferring the plate in the above-mentioned embodiment 1, the horizontal displacement of the sleeve block 23 will also drive the bending plate 44 and the horizontal rack 45 to move synchronously, and as the horizontal rack 45 moves toward the direction close to the door frame 11, the reversing gear 41 will be prompted to rotate clockwise during the horizontal displacement process. The rotation direction can be referred to Fig.11 As shown, as the reversing gear 41 rotates clockwise, the vertical rack 43 meshing therewith is driven to gradually move downward under the action of the sliding groove limiter on the door panel 42 and the door frame 11, thereby driving the door panel 42 to move downward synchronously. When the sleeve block 23 moves to the final position and the plate is conveyed to the stamping position directly above the fixed mold 14, the door panel 42 also moves downward to the final position, that is, the bottom surface of the door panel 42 is attached to the upper surface of the two combination boxes 21, that is, the door panel 42 just covers the open part of the door frame 11.

[0037] Therefore, through the cooperation of the reversing gear 41, the door panel 42 and other components, when the plate is transferred and before the stamping process, the door panel 42 can automatically block the open part of the door frame 11, thereby forming a shielding here. In this way, when the hydraulic cylinder 12 drives the movable mold 13 to stamp the plate, it can prevent the splash of debris due to the rupture of the aluminum alloy plate. The use of the door panel 42 can not only prevent people from contacting the stamping parts, but also avoid the splash of debris, thereby improving the safety of the stamping device.

[0038] When the stamping is completed, the plate is displaced in the reverse horizontal direction and sent out, and the bending plate 44 and the horizontal rack 45 are displaced in the reverse horizontal direction by the sleeve block 23, so that the vertical rack 43 and the door plate 42 are moved up and reset by the reverse rotation of the reversing gear 41.
