Description

Technical Field

[0001] This invention relates to the field of precision forging of aluminum alloy parts, and more particularly to a stamping device for precision forging of aluminum alloy parts for refrigeration and air conditioning. Background Technology

[0002] Stamping is a forming process that uses a press and dies to apply external force to sheet metal, strip, tube, and profiles, causing them to undergo plastic deformation or separation, thereby obtaining workpieces of the required shape and size. Automobile bodies, chassis, fuel tanks and radiator fins, boiler drums, container shells, and silicon steel sheets for motor and electrical appliances are all examples of stamping processes. Instruments, household appliances, bicycles, office machinery, and household utensils also contain a large number of stamped parts. Stamping and forging both belong to plastic processing and are collectively referred to as forging and pressing. Air conditioners are used in many people's lives, and in the production process of air conditioners, it is often necessary to stamp the refrigeration components inside the air conditioner, including precision aluminum alloy forgings used in air conditioners. Patent CN210701908U discloses a stamping device for producing air conditioning refrigeration components, including a connecting base. A bearing is fixedly installed on the left side wall of the connecting base's inner cavity, and a housing is fixedly installed on the right side of the connecting base. A servo motor is fixedly installed at the bottom of the housing's inner cavity. A threaded rod is fixedly installed on the output shaft of the servo motor, with one end penetrating and extending into the connecting base and fixedly connected to the bearing. Movable blocks are threadedly connected to both sides of the outer side of the threaded rod. The bottom of each movable block is movably connected to the bottom of the connecting base's inner cavity. A stabilizing plate is fixedly installed on the top of each movable block, with one end penetrating and extending outwards from the connecting base. This stamping device for producing air conditioning refrigeration components has a simple overall structure, improves the device's vibration damping effect, extends its service life, reduces the impact of vibration on the stamping of parts, and is convenient to use.

[0003] In the aforementioned technologies, when stamping air conditioning components, it is necessary to control the rotation of the threaded rod by a motor and adjust the position of the stabilizing plate to clamp the components. This cannot achieve automatic clamping during the stamping process, which increases production costs. Furthermore, the aforementioned technologies are not conducive to continuous stamping, as the device can only stamp one air conditioning component at a time. This makes loading and unloading cumbersome and requires loading and unloading at the same position, increasing loading and unloading time and reducing the stamping efficiency of the device. Improvements are needed. Therefore, we propose a stamping device for precision forging of aluminum alloy parts for refrigeration and air conditioning. Summary of the Invention

[0004] Purpose of the invention: The purpose of this invention is to provide an automatic clamping mechanism that enables the stamping process, resulting in lower production costs; another purpose of this invention is to provide a mechanism that facilitates continuous stamping, makes loading and unloading convenient, and improves stamping efficiency.

[0005] Technical solution: A stamping device for precision forging of aluminum alloy parts for refrigeration and air conditioning, including a rotary drive mechanism, and a rotary feeding mechanism is provided above the rotary drive mechanism; A stamping mechanism is provided on the left side of the rotation drive mechanism; The rotating feeding mechanism includes a turntable, the upper surface of which is provided with multiple stamping grooves, the inner sidewall of which is integrally formed with two receiving grooves, the interior of which is provided with ejection cavities below the multiple stamping grooves, the inner side of which is slidably connected with a clamping plate, the interior of which is slidably connected with an ejection plate, and the upper surface of which is fixedly connected with multiple ejection columns inside the stamping grooves; Multiple rotating heads are fixedly connected to the lower surface of the ejector plate. A traction rod is rotatably connected to the outer side wall of the rotating head through a rotating shaft. A rotating head is rotatably connected to the bottom end of the traction rod through a rotating shaft. A connecting plate is slidably connected to the interior of the ejector cavity below the ejector plate. The connecting plate is fixedly connected to the opposite side of the rotating head. A push rod is fixedly connected to the side of the connecting plate near the rotating head. Multiple vertical rods are fixedly connected to the left and right sides of the upper surface of the ejector plate. The top of each vertical rod extends into the interior of the storage slot and is rotatably connected to a second traction rod via a pivot. The end of the second traction rod away from the vertical rod is rotatably connected to a third rotating head via a pivot. The third rotating head is fixedly connected to the opposite side of the clamping plate.

[0006] Furthermore, the rotation drive mechanism includes a concave base, an elastic support mechanism is provided at the center of the inner lower surface of the concave base, a gear is sleeved on the outer wall of the elastic support mechanism, a motor is fixedly connected to the inner lower surface of the concave base to the right of the elastic support mechanism, a dial is fixedly connected to the top of the output shaft of the motor, and an arc-shaped dial tooth is integrally formed on the outer wall of the dial.

[0007] Furthermore, the elastic support mechanism includes a hollow tube, with a support column slidably connected inside the hollow tube, and a buffer spring fixedly connected between the support column and the hollow tube.

[0008] Furthermore, the bottom of the hollow tube is rotatably connected to the inner lower surface of the concave base via a rotating shaft, the outer wall of the hollow tube is fixedly connected to the inner side of the gear, and the top of the support column is fixedly connected to the bottom of the turntable.

[0009] Furthermore, a support platform is fixedly connected to the top of the concave base outside the support column, and a stop ring is fixedly connected to the upper surface of the support platform outside the turntable, with a notch on the upper surface of the stop ring.

[0010] Furthermore, multiple return springs are fixedly connected between the connecting plate and the ejector cavity.

[0011] Furthermore, the end of the push rod away from the connecting plate extends to the outer side of the turntable and is integrally formed with a trapezoidal pressure head.

[0012] Furthermore, the stamping mechanism includes a mounting frame, a hydraulic telescopic rod is fixedly connected to the upper surface of the mounting frame, the bottom end of the hydraulic telescopic rod extends through to the inner side of the mounting frame and is fixedly connected to a stamping head, and the bottom of the mounting frame is fixedly connected to the left side of the concave base.

[0013] Furthermore, an intelligent controller is fixedly connected to the front surface of the concave base.

[0014] Beneficial effects: The intelligent controller intelligently controls the motor drive, so that when the motor starts, the arc-shaped moving teeth move the gear, driving the turntable to rotate a quarter of the way in one go. This allows the four stamping slots on the turntable to rotate sequentially to the bottom of the stamping mechanism, enabling continuous stamping of the workpiece and improving work efficiency. Compared with the traditional method of stamping and loading / unloading at one station, it can realize stamping and loading / unloading operations much faster. As the stamping groove located on the right side of the turntable rotates and moves downwards towards the stamping mechanism, the push rod contacts the inner wall of the abutment ring through the trapezoidal pressure head and is squeezed. At this time, the ejector plate is pulled down by the first traction rod. Then, under the pull of the vertical rod and the second traction rod, the two adjacent clamping plates move closer to each other, thereby clamping the workpiece. On the one hand, this can prevent the workpiece inside the stamping groove from shaking during the rotation of the turntable driven by the motor. On the other hand, it can ensure the stable clamping of the workpiece after it moves to the bottom of the stamping mechanism, which is convenient for subsequent stamping work and avoids the problem of poor workpiece stamping effect caused by workpiece displacement during the stamping process. After the stamping slot changes position, i.e., when the push rod is inside the notch, the clamping plate retracts and retracts into the slot under the push of the return spring, and the ejector pin extends into the stamping slot. The two clamping plates separate, making it easier to remove and place the workpiece processed inside the stamping slot at this position. Thus, the stamped workpiece can be taken out through the stamping slot in front of the turntable, and a new workpiece can be placed through the stamping slot on the right side of the turntable. This effectively improves the loading and unloading operation time without affecting the stamping process, thus improving work efficiency. Attached Figure Description

[0017] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0018] Example like Figure 1 , Figure 2 and Figure 5 As shown, a stamping device for precision aluminum alloy forgings for refrigeration and air conditioning is provided, including a rotary drive mechanism 1. The rotary drive mechanism 1 includes a concave base 101. An elastic support mechanism 4 is provided at the center of the inner lower surface of the concave base 101. A gear 102 is sleeved on the outer wall of the elastic support mechanism 4. A motor 103 is fixedly connected to the inner lower surface of the concave base 101 to the right of the elastic support mechanism 4. A toggle disc 104 is fixedly connected to the top of the output shaft of the motor 103. An arc-shaped toggle tooth 105 is integrally formed on the outer wall of the toggle disc 104. A smart controller 109 is fixedly connected to the front surface of the concave base 101; The elastic support mechanism 4 includes a hollow tube 401, a support column 402 is slidably connected inside the hollow tube 401, and a buffer spring 403 is fixedly connected between the support column 402 and the hollow tube 401. The bottom of the hollow tube 401 is rotatably connected to the inner lower surface of the concave base 101 via a rotating shaft, and the outer wall of the hollow tube 401 is fixedly connected to the inner side of the gear 102.

[0019] The top of the concave base 101 is fixedly connected to the support platform 106 on the outside of the support column 402; When the device is in use, the intelligent controller 109 controls the motor 103, which drives the dial 104 to rotate. Then, the arc-shaped dial teeth 105 move the gear 102 intermittently. The intelligent controller 109 intelligently controls the motor 103 to start, so that when the arc-shaped dial teeth 105 move the gear 102, the hollow tube 401 rotates a quarter stroke.

[0020] like Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, a rotating feeding mechanism 2 is provided above the rotating drive mechanism 1; The rotating feeding mechanism 2 includes a turntable 201. The upper surface of the turntable 201 is provided with multiple stamping grooves 202. The inner sidewall of the stamping grooves 202 is integrally formed with two receiving grooves 203. The interior of the turntable 201 is provided with ejection cavities 204 below the multiple stamping grooves 202. A clamping plate 205 is slidably connected to the inner side of the stamping grooves 202. An ejection plate 206 is slidably connected to the interior of the ejection cavity 204. Multiple ejection columns 207 are fixedly connected to the upper surface of the ejection plate 206 inside the stamping grooves 202. Multiple rotating heads 208 are fixedly connected to the lower surface of the ejector plate 206. A traction rod 209 is rotatably connected to the outer wall of the rotating head 208 via a rotating shaft. A rotating head 210 is rotatably connected to the bottom end of the traction rod 209 via a rotating shaft. A connecting plate 211 is slidably connected to the interior of the ejector cavity 204 below the ejector plate 206. The connecting plate 211 is fixedly connected to the opposite side of the rotating head 210. A push rod 212 is fixedly connected to the side of the connecting plate 211 near the rotating head 210. Multiple vertical rods 213 are fixedly connected to the left and right sides of the upper surface of the ejector plate 206. The top of the vertical rods 213 penetrates into the interior of the storage slot 203 and is rotatably connected to a second traction rod 214 via a rotating shaft. The end of the second traction rod 214 away from the vertical rod 213 is rotatably connected to a third rotating head 215 via a rotating shaft. The third rotating head 215 is fixedly connected to the opposite side of the clamping plate 205. Multiple return springs 216 are fixedly connected between the connecting plate 211 and the ejection cavity 204.

[0021] The end of the push rod 212 away from the connecting plate 211 extends to the outside of the turntable 201 and is integrally formed with a trapezoidal pressure head 217; The top of the support column 402 is fixedly connected to the bottom of the turntable 201; The upper surface of the support platform 106 is fixedly connected to the outer side of the turntable 201 with a stop ring 107, and the upper surface of the stop ring 107 has a notch 108. There are four stamping slots 202, which are used to store workpieces. When the stamping slot 202 is on the left, the workpiece at this position can be stamped by starting the stamping mechanism 3. When the stamping slot 202 is in front, it is used for workpiece removal. When the stamping slot 202 is on the right, it is used for placing workpieces. When the stamping slot 202 is in the rear, the internal workpiece is in a state of waiting to be stamped. When the motor 103 drives, the turntable 201 rotates under the drive of the hollow tube 401, so that multiple stamping slots 202 can rotate sequentially to the underside of the stamping mechanism 3, thereby realizing the effect of sequential displacement and stamping of the air conditioning components inside multiple stamping slots 202. As the stamping groove 202 located to the right of the turntable 201 rotates and moves downward toward the stamping mechanism 3, the push rod 212 contacts the inner wall of the abutment ring 107 through the trapezoidal pressure head 217 and is squeezed. At this time, the ejector plate 206 is pulled down by the first traction rod 209. Then, under the pull of the vertical rod 213 and the second traction rod 214, the two adjacent clamping plates 205 move closer to each other, thereby clamping the workpiece. On the one hand, this can prevent the workpiece inside the stamping groove 202 from shaking during the rotation of the turntable 201 driven by the motor 103. On the other hand, it can ensure the stable clamping of the workpiece after it moves to the bottom of the stamping mechanism 3, which is convenient for subsequent stamping work and avoids the problem of poor workpiece stamping effect caused by workpiece displacement during the stamping process. After stamping is completed, the motor 103 is driven again to control the turntable 201 to rotate one-quarter. At this time, the stamping groove 202 of the processed workpiece will rotate to the front. The push rod 212 will be inside the notch 108. Under the push of the return spring 216, the clamping plate 205 will retract and be stored inside the groove 203, and the ejector pin 207 will extend into the stamping groove 202. At this time, it is convenient to take out the processed workpiece inside the stamping groove 202 at this position. The push rod 212 at the stamping groove 202 on the right side of the turntable 201 will also extend into the notch 108. At this time, since the two clamping plates 205 are separated, it is convenient to put a new workpiece at this position.

[0022] like Figure 3 As shown, a stamping mechanism 3 is provided on the left side of the rotation drive mechanism 1; The stamping mechanism 3 includes a mounting frame 301, a hydraulic telescopic rod 302 is fixedly connected to the upper surface of the mounting frame 301, the bottom end of the hydraulic telescopic rod 302 extends through to the inner side of the mounting frame 301 and is fixedly connected to a stamping head 303, and the bottom of the mounting frame 301 is fixedly connected to the left side of the concave base 101. When the hydraulic telescopic rod 302 is activated, the punch head 303 will descend. At this time, the punch head 303 will punch the workpiece stored in the punching groove 202 directly below. During the punching process, the support column 402 will compress the buffer spring 403 to retract and cause the turntable 201 to descend, which will have a buffering effect during the punching process. Workflow: Workpieces to be stamped are placed inside multiple stamping slots 202, and then the stamping mechanism 3 stamps the workpieces directly below. Next, control the stamping mechanism 3 to reset, and then control the motor 103 to drive the turntable 201 to rotate by one-quarter through the intelligent controller 109, so that the workpiece inside the next stamping groove 202 moves to below the stamping mechanism 3. Continue to control the stamping mechanism 3 to start stamping. At the same time, the processed workpiece, that is, the workpiece moved to the inside of the stamping groove 202 in front of the upper surface of the turntable 201, can be taken out. After the stamping is completed, control the stamping mechanism 3 to reset, continue to control the turntable 201 to move, and then take out the workpiece in front of the upper surface of the turntable 201. At the same time, put a new workpiece into the stamping groove 202 on the right side of the upper surface of the turntable 201. Repeat the operation until multiple workpieces are stamped and the device is closed.

[0023] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
