A continuous stamping die for compressor muffler

Abstract

This utility model relates to the field of stamping die technology, and in particular to a continuous stamping die for a compressor muffler. The technical solution includes a bottom die and a discharge port located at the bottom of the bottom die, as well as a pair of base plates fixedly connected to the bottom of the bottom die. A rectangular spring plate is slidably connected inside the base plates. This utility model utilizes the cooperation of the bottom die, base plates, rectangular spring plate, and cylinder. In use, the cylinder drives an L-shaped stop plate to push a stop block, causing the rectangular spring plate to compress a first spring and store force. When the stop block abuts against the rectangular stop block, the first spring releases its force, and the rectangular spring plate springs towards the discharge port to eject waste material. The piston rod of the cylinder drives the L-shaped stop plate to reciprocate in this manner, thus achieving repeated springing of the rectangular spring plate towards the discharge port. This method automatically clears the discharge port through the springing mechanism, solving the problem of easy blockage at the stamping die discharge port, ensuring smooth material discharge, and improving production efficiency and stamping continuity.

Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a continuous stamping die for a compressor muffler. Background Technology

[0002] The compressor muffler in a refrigerator is a key component for reducing compressor operating noise. It is typically installed in the exhaust or intake pipe and its structural design attenuates airflow pulsation noise. These are mostly thin-walled metal parts (such as the outer casing and perforated plates), requiring mass production and high precision. Continuous stamping dies can automate and continuously produce these processes by using multi-station progressive stamping, completing blanking, punching, bending, and forming on the same die. This ensures dimensional consistency and surface precision of the muffler's resonance cavity and sound-absorbing holes, significantly improving efficiency and reducing costs to meet mass production needs. However, in existing technologies, the bottom discharge port of some continuous stamping dies is too close to the upper surface of the support platform, resulting in a narrow discharge space. When workpieces or scrap fall, they are prone to colliding with the platform and accumulating, especially long, coiled scrap which easily entangles and "bridges," obstructing discharge and causing frequent shutdowns for cleaning. This severely impacts production efficiency and stamping continuity. Utility Model Content

[0003] The purpose of this invention is to address the problem that in some existing continuous stamping dies, the distance between the bottom discharge port and the support platform is too close, resulting in a narrow discharge space. When workpieces or scrap fall, they are prone to deflection and collision with the table surface and accumulate. In particular, long strips and curled scraps are more likely to get tangled and "bridge" to obstruct discharge, requiring frequent machine stops for cleaning, which seriously affects production efficiency and stamping continuity. This invention proposes a compressor silencer continuous stamping die.

[0004] The technical solution of this utility model is as follows: A continuous stamping die for a compressor muffler includes a bottom die and a discharge port located at the bottom of the bottom die. It also includes: a pair of base plates fixedly connected to the bottom of the bottom die, with a rectangular spring plate slidably connected inside the base plates; a springing mechanism at the bottom of the bottom die that springs towards the discharge port after accumulating force; a first groove formed on the base plates, with wing rods fixedly connected to the sidewalls of the rectangular spring plates inside each groove; and a pushing mechanism on the upper surface of the base plates that moves the springing mechanism to accumulate force.

[0005] Optionally, the spring mechanism includes a support plate fixedly connected to the middle of the base plate, and a pair of first springs fixedly connected to the support plate, the ends of the first springs away from the support plate being fixedly connected to a rectangular spring plate.

[0006] Optionally, the pushing mechanism includes a pair of synchronously switched cylinders, the cylinders are fixedly connected to the upper surface of the base plate, the piston rods of the cylinders are fixedly connected to L-shaped abutments, the wing rods are provided with telescopic grooves, the inside of the telescopic grooves are fixedly connected to a second spring, the top of the second springs are fixedly connected to a stop block that is pressed against by the L-shaped abutment, and the top of the stop block is coated with lubricating oil.

[0007] Optionally, the pushing mechanism further includes a pair of rectangular blocks fixedly connected to the outer walls on both sides of the bottom mold and corresponding to the L-shaped abutment plate. The abutment plate has an inclined abutment surface that automatically retracts into the telescopic groove after abutting against the rectangular block.

[0008] Optionally, the pair of base plates and wing rods are symmetrically arranged with a rectangular spring plate as the center.

[0009] Optionally, the middle of the pair of base plates is provided with a second sliding groove that engages the outer walls of both sides of the rectangular spring plate.

[0010] Optionally, the bottom of the rectangular spring plate is provided with a groove.

[0011] Optionally, the bottom mold may also be provided with a top mold that moves up and down.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] This invention utilizes the cooperation of a bottom mold, base plate, rectangular spring plate, and cylinder. During operation, the cylinder drives an L-shaped abutment plate to push a stop block, compressing a first spring in the rectangular spring plate. When the stop block presses against the rectangular stop block, the first spring releases its force, causing the rectangular spring plate to spring towards the discharge port, ejecting waste material. The piston rod of the cylinder drives the L-shaped abutment plate in a reciprocating motion, thus achieving repeated spring-loaded movement of the rectangular spring plate towards the discharge port. This method automatically clears the discharge port through the spring mechanism, solving the problem of easy blockage at the stamping die discharge port, ensuring smooth material output, and improving production efficiency and stamping continuity.

[0025] Example

[0026] like Figures 1 to 4 As shown, this utility model proposes a continuous stamping die for a compressor muffler, including a bottom die 1 and a discharge port 25 located at the bottom of the bottom die 1. The discharge port 25 is located at the bottom of the bottom die 1, through which the stamped workpiece or waste is discharged. The top of the bottom die 1 also has a vertically movable and corresponding top die, which cooperates with the bottom die 1 through a downward movement to complete the stamping action. A pair of base plates 2 are fixedly connected to the bottom of the bottom die 1. The base plates 2 are fixed to the bottom of the bottom die 1, and a second sliding groove 22 is provided in the middle to hold a rectangular spring plate 3. A pushing mechanism is installed on the upper surface to provide mounting support for each component. The middle of the pair of base plates 2 has a second sliding groove 22 that holds the outer walls of both sides of the rectangular spring plate 3. The second sliding groove 22 is located in the middle of the base plates 2, holding the outer walls of both sides of the rectangular spring plate 3, restricting its movement direction and providing a sliding track.

[0027] Among them, such as Figure 1 and Figure 3 As shown, a rectangular spring plate 3 is slidably connected inside the base plate 2. The rectangular spring plate 3 ejects waste material from the discharge port 25 through the elastic force of the first spring 23, preventing blockage. A groove is provided at the bottom of the rectangular spring plate 3 to reduce its weight. A first sliding groove 21 is provided on the base plate 2, which is slidably connected to the wing rod 4 inside, guiding the wing rod 4 to move the rectangular spring plate 3. Wing rods 4 are fixedly connected to the side wall of the rectangular spring plate 3 inside the first sliding groove 21. The wing rods 4 are fixedly connected to the side wall of the rectangular spring plate 3 and located inside the first sliding groove 21, moving the rectangular spring plate 3 under the action of the pushing mechanism. The pair of base plates 2 and wing rods 4 are symmetrically arranged with the rectangular spring plate 3 as the center.

[0028] Secondly, such as Figure 3 As shown, the bottom of the bottom mold 1 is also provided with a spring mechanism that springs towards the discharge port 25 after accumulating force. The spring mechanism includes a support plate 24 fixedly connected to the middle of the base plate 2. A pair of first springs 23 are fixedly connected to the support plate 24. One end of the first spring 23 is fixed to the support plate 24 in the middle of the base plate 2, and the other end is connected to the rectangular spring plate 3. Through elastic accumulating and releasing force, the rectangular spring plate 3 is pushed towards the discharge port 25. The ends of the first springs 23 away from the support plate 24 are all fixedly connected to the rectangular spring plate 3.

[0029] In addition, such as Figure 2 and Figure 4 As shown, the upper surface of the base plate 2 is provided with a pushing mechanism that moves the spring material mechanism to store power. The pushing mechanism includes a pair of synchronously switched cylinders 41. The cylinders 41 are fixed to the upper surface of the base plate 2 and controlled by the synchronous switches. The piston rod drives the L-shaped abutment plate 42 to move, providing power to the pushing mechanism. The cylinders 41 are fixedly connected to the upper surface of the base plate 2. The piston rods of the cylinders 41 are fixedly connected to the L-shaped abutment plates 42. The L-shaped abutment plates 42 are connected to the piston rods of the cylinders 41. When moving, they abut against the abutment block 45, pushing the wing rod 4 and the rectangular spring plate 3 to move and store power. Each wing rod 4 has a telescopic groove 43. A second spring 44 is fixedly connected inside the telescopic groove 43. The second spring 44 is located inside the telescopic groove 43 and its top end is connected to the abutment block 45. The abutment block 45 is reset through elastic action. The elastic force of the second spring 44 is small, and its function is to reduce friction when the abutment block 45 abuts against the lower surface of the L-shaped abutment plate 42. The top of each of the second springs 44 is fixedly connected to a stop block 45 that is pressed against by an L-shaped stop plate 42. The top of the stop block 45 is coated with lubricating oil to reduce friction when the top of the stop block 45 is pressed against the lower surface of the L-shaped stop plate 42.

[0030] It is worth noting that, such as Figure 2 and Figure 4 As shown, the pushing mechanism also includes a pair of rectangular blocks 5 fixedly connected to the outer walls of both sides of the bottom mold 1, corresponding to the L-shaped abutment plates 42. The rectangular blocks 5 are fixed to the outer walls of both sides of the bottom mold 1, corresponding to the L-shaped abutment plates 42. When the abutment plates 45 are pressed against the bottom mold 1, they cause the abutment plates 45 to retract, triggering the first spring 23 to release its elastic force. The abutment plates 45 are provided with inclined abutment surfaces 46 that automatically retract into the telescopic groove 43 after pressing against the rectangular blocks 5.

[0031] In this embodiment, when using a compressor muffler for continuous stamping of the die, the base plate 2 of the bottom die 1 is fixed to the workbench of the equipment. When a pair of cylinders 41 of the pushing mechanism are started synchronously, their piston rods drive the L-shaped abutment plate 42 to move and abut against the abutment block 45. Then, the abutment block 45 drives the locked wing rod 4 to move within the first slide groove 21 until the L-shaped abutment plate 42 pushes the abutment block 45 against the rectangular stop block 5. After the inclined abutment surface 46 on the abutment block 45 abuts against the rectangular stop block 5, it can retract into the telescopic groove 43. Figure 4As shown, at this time, the L-shaped abutment 42 is not stuck in the corresponding abutment block 45, and the rectangular spring plate 3, through the elastic thrust of a pair of first springs 23, can quickly eject the workpiece material discharged from the discharge port 25 into the second chute 22, thereby preventing material blockage in the second chute 22 and ensuring smooth discharge. After the piston rod of the cylinder 41 drives the L-shaped abutment 42 back to its original position, the top of the telescopic groove 43 is no longer stuck by the lower surface of the L-shaped abutment 42. Then, the abutment block 45 can return to its original position through the elastic thrust of the second spring 44, so that the L-shaped abutment 42 moves back and forth towards the rectangular stop block 5, thereby realizing the repeated force accumulation of the rectangular spring plate 3 towards the discharge port 25.
