Description

Technical Field

[0001] This utility model belongs to the field of punch press technology, specifically relating to a punch press capable of stable processing. Background Technology

[0002] In the modern manufacturing process of rice cookers, punch presses play a crucial role. They are widely used in both the stamping of the inner pot and the processing of the outer shell. For the inner pot, a punch press uses a die to press the metal sheet, transforming it from a flat sheet into the shape required by the design. Similarly, stamping is often used in the processing of the outer shell to enhance both aesthetics and functionality.

[0003] There are some shortcomings in the actual use of punch presses for these processing operations. Currently, the die of a punch press is generally fixed to the output end of the stamping instrument. When different workpieces need to be processed, such as switching from processing the inner pot to processing the outer shell, or processing the inner pot or outer shell of different models of rice cookers, the existing die at the end of the stamping instrument must be disassembled and a new die installed. This die replacement method has obvious drawbacks. First, the die disassembly process causes the machine to stop working. In a large-scale industrial production environment, machine downtime will cause production interruptions, greatly reducing work efficiency. Every downtime means a loss of production time, making continuous and efficient production impossible. Second, the disassembly and installation of the die is relatively cumbersome, requiring professional technicians to spend a lot of time and effort, further reducing the working efficiency of the punch press. Utility Model Content

[0004] This invention provides a punch press that can be stably processed, which has the characteristics of improving the efficiency of mold switching and reducing the impact on production and processing.

[0005] This utility model provides the following technical solution: It includes a punch press body, a punching telescopic rod, a chamber, and several punching dies. A rotating central shaft is installed inside the chamber, and the bottom of the rotating central shaft is rotatably connected to the inner wall of the chamber. A supporting ring is provided on the side wall of the rotating central shaft. Several punching dies are arranged in a circumferential array at the bottom of the supporting ring. The output end of the chamber contacts the top of the supporting ring. A connecting ring is slidably connected to the side wall of the rotating central shaft. Several connecting rods are installed on the side wall of the connecting ring, and one end of each connecting rod is installed inside the supporting ring. The supporting ring drives several punching dies to rotate alternately to a position below the chamber. A drive motor is installed at the bottom of the rotating central shaft, and the drive motor is installed inside the punch press body.

[0006] The rotating central shaft has a bottom ring installed on its side wall. The bottom ring is rotatably connected to the inner wall of the bottom side of the empty compartment. A return spring is installed between the bottom ring and the connecting ring. The return spring pushes the connecting ring upward to return to its original position.

[0007] The bottom ring is rotatably connected to a plurality of spherical rolling elements, and the plurality of spherical rolling elements are slidably connected to the inner wall of the empty compartment.

[0008] The rotating central shaft has several sliding grooves on its side wall, and several connecting blocks are installed on the inner side of the connecting ring. The positions of the connecting blocks correspond one-to-one with the positions of the sliding grooves, and the connecting blocks are slidably connected to the inner wall of the corresponding sliding groove.

[0009] The top of the support ring is equipped with several sleeves, and the sleeves are perpendicularly corresponding to the positions of several stamping dies. The empty chamber is inserted into the inner wall of the sleeves.

[0010] Among them, several of the sleeves are equipped with telescopic positioning rods on the side near the rotating central axis, and the empty compartment sidewall has a slot, the output end of the telescopic positioning rod is inserted into the slot of the empty compartment sidewall.

[0011] The empty compartment has a telescopic rod installed on the inner wall of the top side, a hexagonal insert rod installed at the bottom of the telescopic rod, and a hexagonal slot opened at the top of the rotating central shaft. The hexagonal insert rod is inserted into the inner wall of the hexagonal slot.

[0012] The beneficial effects of this utility model are: by rotating the central shaft to drive the support ring to rotate and adjust, there is no need to stop the machine to change the stamping die. It can be switched by simply rotating, which can realize the switching of the required stamping die. This reduces the steps and time required for replacement, reduces the production process interruption time caused by machine downtime, helps to maintain work efficiency, realize continuous and efficient production, and reduce the economic losses caused by downtime.

[0019] Please see Figures 1-4 The present invention provides the following technical solution: including a punch press body 1, a punching telescopic rod 11, an empty chamber 12 and several punching dies 2, a rotating central shaft 3 is installed inside the empty chamber 12, the bottom of the rotating central shaft 3 is rotatably connected to the inner wall of the empty chamber 12, a support ring 31 is provided on the side wall of the rotating central shaft 3, several punching dies 2 are distributed in a circumferential array at the bottom of the support ring 31, the output end of the empty chamber 12 is in contact with the top of the support ring 31, a connecting ring 32 is slidably connected to the side wall of the rotating central shaft 3, several connecting rods 321 are installed on the side wall of the connecting ring 32, one end of each connecting rod 321 is installed inside the support ring 31, the support ring 31 drives several punching dies 2 to rotate alternately to the position below the empty chamber 12, a drive motor 33 is installed at the bottom end of the rotating central shaft 3, and the drive motor 33 is installed inside the punch press body 1.

[0020] In this implementation scheme: the empty chamber 12 accommodates and makes room for the internal components; the rotating central shaft 3 supports and drives the connecting ring 32 to rotate; the connecting ring 32 supports the supporting ring 31 through several connecting rods 321; when the connecting rods 321 are in use, a gap is created between the supporting ring 31 and the rotating central shaft 3, facilitating observation of the equipment's operation and reducing its weight; the supporting ring 31 supports and rotates several different types of stamping dies 2; the empty chamber 12 is positioned above the supporting ring 31 and the stamping dies 2, allowing the empty chamber 12 to push the supporting ring 31 when it presses down, enabling the supporting ring 31 to drive the stamping dies 2 to stamp the rice cooker parts; and the drive motor 33 drives the rotating central shaft. 3. The rotation is controlled by the drive motor 33, which drives the rotation of the central shaft 3. The rotation is adjusted by the internal PLC control unit of the equipment, so that when the support ring 31 drives the stamping die 2 to switch, the support ring 31 can rotate at an accurate angle, which facilitates the alignment and connection of the stamping die 2 with the empty chamber 12. There are multiple ways to achieve this, which is the prior art and not the improvement point of this new invention. The triggering principle will not be described in detail here. This enables the switching of the required stamping die 2 without stopping the machine to replace the stamping die 2. Only rotation is required for switching, which reduces the steps and time required for replacement, reduces the production process interruption time caused by machine downtime, helps maintain work efficiency, achieves continuous and efficient production, and reduces the economic losses caused by downtime.

[0021] A bottom ring 34 is installed on the side wall of the rotating central shaft 3. The bottom ring 34 is rotatably connected to the inner wall of the bottom side of the empty chamber 12. A return spring 341 is installed between the bottom ring 34 and the connecting ring 32. The return spring 341 pushes the connecting ring 32 upward to return to its original position. The bottom ring 34 supports the return spring 341, and the return spring 341 provides elastic support to the connecting ring 32, so that the return spring 341 can push the connecting ring 32 upward. After the empty chamber 12 is used to press down on the support ring 31 and the stamping die 2, the empty chamber 12 shortens. The connecting ring 32 completes its return under the elastic restoring force of the return spring 341, and makes the support ring 31 in close contact with the empty chamber 12, which is conducive to the support ring 31 sensing the expansion and contraction of the empty chamber 12 in a timely manner.

[0022] The bottom ring 34 has several spherical rolling elements 342 rotatably connected to its bottom end. These spherical rolling elements 342 are all slidably connected to the inner wall of the empty chamber 12. When the rotating central shaft 3 drives the connecting ring 32 and the return spring 341 to rotate, the rotating central shaft 3 can also drive the spherical rolling elements 342 to rotate, preventing interference with the return spring 341. When the return spring 341 rotates, it contacts the empty chamber 12 through the several spherical rolling elements 342, reducing the frictional resistance and frictional loss between the bottom ring 34 and the empty chamber 12.

[0023] The rotating central shaft 3 has several sliding grooves 35 on its side wall, and several connecting blocks 322 are installed on the inner side of the connecting ring 32. The positions of the connecting blocks 322 and the sliding grooves 35 are one-to-one. The connecting blocks 322 are slidably connected to the inner wall of the corresponding sliding groove 35. The sliding grooves 35 provide sliding tracks for the connecting blocks 322. When the rotating central shaft 3 rotates, it can be driven to rotate synchronously through the sliding grooves 35 and the connecting blocks 322, thereby completing the switching of the stamping die 2. During the stamping operation, when the support ring 31 drives the connecting ring 32 to slide up and down, the connecting ring 32 can achieve a stable connection with the press body 1 through the sliding grooves 35, preventing the connecting ring 32 from causing the support ring 31 to shake randomly, thus improving the stability during use.

[0024] The top of the support ring 31 is equipped with several sleeves 4, which are perpendicularly corresponding to the positions of several stamping dies 2. The empty chamber 12 is inserted into the inner wall of the sleeve 4. The internal space of the sleeve 4 corresponds to the size and position of the empty chamber 12. When the empty chamber 12 is in use, it is inserted into the sleeve 4, which makes the connection between the support ring 31 and the empty chamber 12 more stable and prevents the support ring 31 from rotating and shaking during use.

[0025] Several sleeves 4 are equipped with telescopic positioning rods 41 near the rotating central shaft 3. The side wall of the empty chamber 12 has a slot, and the output end of the telescopic positioning rod 41 is inserted into the slot of the side wall of the empty chamber 12. After the empty chamber 12 is connected to the sleeve 4, the telescopic positioning rod 41 is controlled to extend, so that the telescopic positioning rod 41 can connect with the slot of the side wall of the empty chamber 12, thereby completing the locking and limiting between the sleeve 4 and the empty chamber 12, so that the movement of the empty chamber 12 can be consistent with the support ring 31 and the stamping die 2.

[0026] A telescopic rod 5 is installed on the inner wall of the top side of the empty chamber 12. A hexagonal insert rod 51 is installed at the bottom of the telescopic rod 5. A hexagonal slot 36 is opened at the top of the rotating central shaft 3. The hexagonal insert rod 51 is inserted into the inner wall of the hexagonal slot 36. The punch press body 1 supports the telescopic rod 5. The telescopic rod 5 and the hexagonal insert rod 51 are on the same vertical line as the rotating central shaft 3. When the rotating central shaft 3 is rotated and the switching of the stamping die 2 is completed, the telescopic rod 5 extends and pushes the hexagonal insert rod 51 into the hexagonal slot 36, so that the hexagonal slot 36 can limit the rotating central shaft 3 and prevent the rotating central shaft 3 from rotating. Furthermore, the rotating central shaft 3 and the telescopic rod 5 are connected, so that the upper and lower parts of the rotating central shaft 3 can be limited and supported, improving the stability of the rotating central shaft 3 during use and preventing the rotating central shaft 3 from tilting when the empty chamber 12 presses down on the support ring 31.

[0027] The working principle and usage process of this utility model are as follows: When switching the stamping die 2, the control drive motor 33 drives the rotating central shaft 3 to rotate. The rotating central shaft 3 drives the supporting ring 31 to rotate through the connecting ring 32. The supporting ring 31 drives the required stamping die 2 to be transferred to the bottom of the empty chamber 12. Then the empty chamber 12 extends and connects with the sleeve 4. The telescopic positioning rod 41 connects with the slot on the side wall of the empty chamber 12, thereby completing the locking and limiting between the sleeve 4 and the empty chamber 12. This ensures that the movement of the empty chamber 12 is consistent with the supporting ring 31 and the stamping die 2. When the empty chamber 12 is pressed down, it can push the supporting ring 31, so that the supporting ring 31 can drive the stamping die 2 to perform stamping processing on the rice cooker parts. This realizes the switching and use of the required stamping die 2 without stopping the machine to change the stamping die 2. It only requires rotation to switch, which reduces the steps and time required for replacement, reduces the production process interruption time caused by machine downtime, helps maintain work efficiency, achieves continuous and efficient production, and reduces the economic losses caused by downtime.
