Description

Technical Field

[0001] This utility model relates to the field of skeleton processing technology, and in particular to a cutting and punching side punching mold for processing automobile seat skeletons. Background Technology

[0002] As the core load-bearing structure of automotive seats, the car seat frame occupies an important position in the automotive manufacturing industry. As a key link connecting the seat cover, adjustment mechanism, and safety system, its structural strength, dimensional accuracy, and assembly consistency have a decisive impact on the overall vehicle's ride comfort, safety performance, and production efficiency. In the manufacturing process of the car seat frame, stamping is one of the core processes. Among these, the cutting and punching side-punching die is a core component for achieving the simultaneous processing of complex geometries and multiple holes. Its processing accuracy, operational stability, and ease of maintenance directly determine the quality stability of the frame product and the cycle efficiency of the production line.

[0003] Especially in the critical process of side punching and cutting forming, existing stamping die technology has gradually revealed a series of obvious limitations and technical problems when processing seat frames made of high-strength steel and complex cross-section profiles. Specifically, existing technologies, such as utility model patent CN217889239U, disclose a side punching die for processing automotive seat frames, including a base. The top of the base is arranged sequentially along the length direction with a cylinder, a moving die, and a fixed die. The cylinder is mounted on the base via a mounting block. The moving die is slidably disposed on the base, and the fixed die is fixed on the base. Punching holes are provided on both sides of the fixed die. A pushing mechanism is provided on the side of the fixed die away from the moving die. The pushing mechanism is used to push the processed automotive seat frame out of the fixed die. Through the set pushing mechanism and linkage, after the automotive seat frame punching is completed, the processed automotive seat frame can be automatically pushed out of the fixed die, improving the material handling efficiency of the automotive seat frame. Although this structure improves the level of automation of material handling to a certain extent, it still has significant defects in practical applications.

[0004] After continuous high-intensity stamping operations, existing technologies tend to accumulate metal shavings and stamping residues on the surface of the die cavity, punch, and guide components. Failure to clean these residues in a timely manner will affect the dimensional accuracy and surface quality of subsequent stamped parts. Therefore, in order to address the prominent problems of difficult die cleaning and low maintenance efficiency in existing technologies, we urgently need an innovative cutting and punching side punching die for processing automotive seat frames to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a cutting and punching side punching die for processing automotive seat frames, which solves the problem in the prior art that after continuous high-intensity stamping operations, metal shavings and stamping residues easily accumulate on the surface of the die cavity, punch and guide components, and if not cleaned in time, will affect the dimensional accuracy and surface quality of subsequent stamped parts.

[0006] To achieve the above objectives, this utility model provides a side punching mold for cutting and punching in the processing of automotive seat frames, including a frame, and a top frame fixedly connected to the top of the frame, and an upper mold provided on the inner side of the top frame;

[0007] A rotating rod is rotatably connected to the inner side of the frame, and a drive motor is fixedly connected to one side of the outer wall of the frame by bolts. The other end of the rotating rod passes through the side wall of the frame and is connected to the output shaft of the drive motor. A lower mold is fixedly connected to the rotating rod. A cylinder is fixedly connected to one side of the top of the top frame by bolts, and the output shaft of the cylinder passes through the top of the top frame and is fixedly connected to the top of the upper mold. An air outlet plate is fixedly connected to one side of the upper part and one side of the lower part of the frame, and a fan is fixedly connected to one side of the outer wall of the frame by bolts. One side of each air outlet plate is connected to the outlet of the fan.

[0008] The lower mold has a connecting plate fixedly connected to one side, and the top side of the connecting plate has a rod. The frame has a pull-out plate detachably connected to one side, and one end of the rod passes through the connecting plate and the pull-out plate in sequence.

[0009] One end of the pull-out panel penetrates through the side wall of the frame, and a handle is fixedly connected to one end of the pull-out panel.

[0010] The inner bottom of the frame is slidably connected to a bottom frame, and both sides of the bottom frame are fixedly connected to sliders, which are slidably connected to the side wall of the frame through grooves.

[0011] One end of the rotating rod is rotatably connected to the inner wall of the frame via a rotating shaft, and the other end of the rotating rod passes through the side wall of the frame via a bearing sleeve.

[0012] One side of the frame is equipped with a connecting pipe, and both ends of the connecting pipe are connected to one side of the two air outlet plates respectively. One end of the connecting pipe is connected to the outlet of the fan.

[0013] This utility model discloses a side punching die for processing automotive seat frames. By incorporating a lower die flipping mechanism consisting of a drive motor and a rotating rod, the lower die automatically flips downwards after processing. This overcomes the limitations of traditional fixed dies that are difficult to clean thoroughly, effectively solving the cleaning inconvenience caused by the enclosed structure and numerous blind spots in existing technologies. Combined with air outlets on the upper and lower sides of the frame and connected fans, airflow can simultaneously clean the surfaces of both the upper and lower dies during the lower die flipping process, using airflow power to remove residues adhering to the die cavity and punch edges. This method removes metal debris and residue from the guide structure, avoiding the inefficiency and incompleteness of manual point-by-point cleaning. It significantly improves the convenience and cleaning quality of mold maintenance, reduces quality problems such as punching burrs and positioning deviations caused by debris accumulation, and thus ensures the dimensional accuracy and surface quality stability of automotive seat frame products. At the same time, the cleaning process can be completed in a short time without disassembling the mold, greatly shortening downtime for maintenance, improving equipment operating efficiency and production cycle, reducing maintenance and replacement costs caused by accelerated wear due to mold contamination, and extending the service life of the mold.

[0021] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

[0022] Please see Figure 1-5 .

[0023] A side punching die for processing automotive seat frames includes a frame 1, and a top frame 2 is fixedly connected to the top of the frame 1, and an upper die 4 is provided on the inner side of the top frame 2.

[0024] A rotating rod 6 is rotatably connected to the inner side of the frame 1, and a drive motor 7 is fixedly connected to one side of the outer wall of the frame 1 by bolts. The other end of the rotating rod 6 passes through the side wall of the frame 1 and is connected to the output shaft of the drive motor 7. A lower mold 5 is fixedly connected to the rotating rod 6. A cylinder 3 is fixedly connected to one side of the top of the top frame 2 by bolts. The output shaft of the cylinder 3 passes through the top of the top frame 2 and is fixedly connected to the top of the upper mold 4. An air outlet plate 10 is fixedly connected to one side of the upper part and one side of the lower part of the frame 1. A fan 15 is fixedly connected to one side of the outer wall of the frame 1 by bolts. One side of each of the two air outlet plates 10 is connected to the outlet of the fan 15.

[0025] First, the blank of the car seat frame to be processed is placed on the upper surface of the lower mold 5 inside the frame 1. Then, the cylinder 3 at the top of the top frame 2 is activated, and the output shaft of the cylinder 3 extends downward, driving the upper mold 4, which is fixedly connected to it, to move downward in the vertical direction until the upper mold 4 and the lower mold 5 are precisely closed, completing multiple stamping processes such as cutting, punching, and side punching of the workpiece. After processing, the cylinder 3 retracts, driving the upper mold 4 to move upward and reset. At this time, the workpiece has been formed and remains on the lower mold 5. For subsequent cleaning operations, the drive motor 7, which is fixedly connected to one side of the outer wall of the frame 1 by bolts, is activated. The output shaft of the drive motor 7 drives the rotating rod 6 to rotate through the transmission connection. Since the lower mold 5 is fixedly connected to the rotating rod 6, the lower mold 5 rotates downward together with the rotating rod 6, making... The original horizontal working surface of the mold is tilted or oriented downwards to facilitate cleaning operations. At the same time, the blower 15 is started, and the airflow generated by the blower 15 is delivered to two air outlet plates 10 through pipes. The two air outlet plates 10 are respectively set on the upper and lower sides of the frame 1, and their air outlets are aimed at the surfaces of the upper mold 4 and the flipped lower mold 5. The high-pressure airflow blows away and cleans the metal shavings, dust and stamping oil stains and other impurities remaining on the mold surface, ensuring that the cavities, punches and mating surfaces of the upper mold 4 and the lower mold 5 are kept clean. After cleaning, the blower 15 and the drive motor 7 are turned off. The drive motor 7 rotates in reverse to drive the lower mold 5 back to the horizontal processing position, thus completing a complete processing and cleaning cycle, and preparing for the next round of workpiece stamping operations.

[0026] Furthermore, a connecting plate 16 is fixedly connected to one side of the lower mold 5, and a rod 17 is provided on the top side of the connecting plate 16. A pull plate 8 is detachably connected to one side of the frame 1, and one end of the rod 17 passes through the connecting plate 16 and the pull plate 8 in sequence. After the mold flipping and airflow cleaning are completed, the mechanical limit and fixation of the flipping angle of the lower mold 5 can be achieved by passing the rod 17 through the connecting plate 16 and the pull plate 8 in sequence. This prevents the lower mold 5 from shaking or resetting due to accidental loosening of the drive motor 7 or the rotating rod 6 during the cleaning process, thereby ensuring that the airflow of the air outlet plate 10 can act stably and continuously on the mold surface, thus achieving the effect of enhancing the stability of the cleaning process and the safety of operation.

[0027] Furthermore, one end of the pull-out plate 8 penetrates the side wall of the frame 1, and a handle plate 9 is fixedly connected to one end of the pull-out plate 8. The operator can directly hold the handle plate 9 to perform the pull-out operation, which facilitates quick installation or removal of the pull-out plate 8, thereby flexibly controlling whether the insertion rod 17 is inserted into the limit position, achieving the effect of improving the ease of operation of the limit structure and the efficiency of human-machine interaction.

[0028] Furthermore, a bottom frame 11 is slidably connected to the inner bottom of the frame 1, and sliders 12 are fixedly connected to both sides of the bottom frame 11. The sliders 12 are slidably connected to the side wall of the frame 1 through the slide groove 13. The bottom frame 11 can be pulled out or pushed in as a whole along the slide groove 13. When the bottom frame 11 is inside the frame 1, it can receive metal shavings and dust blown off from the upper mold 4 and the lower mold 5, preventing them from falling into the equipment or onto the ground. After a certain amount of impurities have accumulated, the bottom frame 11 can be pulled out as a whole by sliding, making it easy to clean. This achieves the effect of facilitating the collection and cleaning of stamping residues and keeping the equipment and working environment clean.

[0029] Furthermore, one end of the rotating rod 6 is rotatably connected to the inner wall of the frame 1 via a rotating shaft, and the other end of the rotating rod 6 passes through the side wall of the frame 1 via a bearing sleeve. Under the drive of the drive motor 7, the rotating rod 6 can achieve stable and low-friction rotational motion. The bearing sleeve provides external support and sealing protection, effectively reducing vibration and wear during rotation, extending the service life of the rotating structure, and achieving the effect of ensuring smooth and reliable flipping action of the lower mold 5, improving transmission accuracy and equipment durability.

[0030] Furthermore, a connecting pipe 14 is provided on one side of the frame 1, and the two ends of the connecting pipe 14 are respectively connected to one side of the two air outlet plates 10. One end of the connecting pipe 14 is connected to the outlet of the fan 15. The airflow generated by the fan 15 is evenly distributed to the upper and lower air outlet plates 10 through the connecting pipe 14, so as to simultaneously supply air to the upper mold 4 and the lower mold 5 after flipping. This avoids the structural complexity caused by multiple independent pipelines and achieves the effect of simplifying the airflow layout, ensuring the balance of airflow output and the comprehensive cleaning coverage.

[0031] In summary:

[0032] When processing the car seat frame, the blank to be processed is first placed on the upper surface of the lower mold 5 inside the frame 1. At this time, the lower mold 5 is fixedly connected by the rotating rod 6 and located inside the frame 1, in a horizontal processing position. Then, the cylinder 3, which is fixedly connected to the top of the top frame 2 by bolts, is activated. The output shaft of the cylinder 3 extends downward, driving the upper mold 4, which is fixedly connected to its top, to move downward in the vertical direction, achieving precise mold closing with the lower mold 5, and completing multiple stamping processes such as cutting, punching, and side punching of the workpiece. After processing, the cylinder 3 retracts, driving the upper mold 4 to move upward and reset. After the workpiece is formed, it remains on the lower mold 5. To clean the mold, the drive motor 7, which is fixedly connected to one side of the outer wall of the frame 1 by bolts, is activated. Its output shaft is transmitted through a transmission... The moving connection drives the rotating rod 6 to rotate. One end of the rotating rod 6 is rotatably connected to the inner wall of the frame 1 through a rotating shaft, and the other end passes through the side wall of the frame 1 through a bearing sleeve. This structure ensures the stability and low friction operation during rotation, reduces vibration and wear, and extends service life. The lower mold 5 flips downwards along with the rotating rod 6, tilting or lowering the working surface of the mold to facilitate cleaning operations. At the same time, the blower 15 is started, and the airflow generated by the blower 15 is delivered through the connecting pipe 14. One end of the connecting pipe 14 is connected to the outlet of the blower 15, and the two ends are connected to the air outlet plates 10 fixedly connected to the upper and lower sides of the frame 1, respectively, to achieve uniform airflow distribution. The air outlets of the two air outlet plates 10 are respectively aligned with the surfaces of the upper mold 4 and the flipped lower mold 5. High-pressure airflow is used to blow away metal debris, dust, oil, and other residues, ensuring the cleanliness of the mold cavity, punch, and mating surfaces. During this process, to prevent displacement of the lower mold 5 due to a loose drive system after flipping, the insert rod 17 on the connecting plate 16 fixed to one side of the lower mold 5 passes sequentially through the connecting plate 16 and the detachably connected pull-out plate 8 on one side of the frame 1. This mechanically limits and fixes the flipping angle, improving the stability and safety of the cleaning process. One end of the pull-out plate 8 penetrates the side wall of the frame 1 and is fixedly connected to a handle plate 9. Operators can easily pull out the pull-out plate 8 by holding the handle plate 9, enabling quick installation or removal and improving the convenience of the limiting operation. Impurities that fall off during the blowing process fall onto the frame 1. On the bottom frame 11, which is slidably connected to the inner bottom, the sliders 12 fixedly connected to both sides of the bottom frame 11 cooperate with the slide grooves 13 on the side wall of the frame 1, so that it can be pulled out or pushed in as a whole along the direction of the slide grooves 13. This facilitates the removal and centralized cleaning of accumulated impurities, effectively preventing debris from scattering and keeping the equipment and environment clean. After cleaning, the blower 15 and drive motor 7 are turned off. The drive motor 7 rotates in reverse, driving the rotating rod 6 and the lower mold 5 to return to the horizontal position, completing a complete processing and cleaning cycle, and preparing for the next round of stamping operation. This overall structure achieves precise mold closing by driving the upper mold 4 through the cylinder 3. The drive motor 7 and the rotating rod 6 work together to drive the lower mold 5 to rotate. The blower 15, the air outlet plate 10, and the connecting pipe 14 constitute a high-efficiency blowing system.The system, consisting of a limiting mechanism comprised of insert rod 17, pull-out plate 8, and handle plate 9, and a chip-collecting structure comprised of base frame 11, slider 12, and slide groove 13, integrates stamping forming and automatic cleaning operations. This solves the problems of inconvenient mold cleaning, easy chip accumulation, and low maintenance efficiency in existing technologies. It significantly improves the thoroughness and convenience of mold cleaning, reduces dimensional deviations and surface defects caused by residues, ensures product quality stability, reduces manual cleaning intensity and downtime, and improves production continuity and cycle efficiency. The rational design and tight fit of each component enhance the reliability and safety of equipment operation, meeting the actual needs of high-strength, high-frequency automotive seat frame stamping production.
