Description

Technical Field

[0001] This invention belongs to the field of tube seat stamping technology, specifically tube seat raw material stamping equipment. Background Technology

[0002] In the production process of steel strip tube seats, the stamping process is a key link, and its processing efficiency and quality play a decisive role in the final product quality. After the stamping device is fed and positioned, the hydraulic pump starts, the hydraulic cylinder drives the upper die to move down, and the punch and die cooperate to stamp. Pressure and flow sensors provide real-time feedback data, the control system adjusts the parameters, and after completion, the upper die is reset, the clamping device and positioning pin are released, and the feeding motor feeds the material to enter the next cycle. Traditional equipment has low stamping accuracy, making it difficult to meet high standards, and low efficiency, making it difficult to meet the needs of large-scale production. The unstable positioning and fixing of the steel strip leads to uneven tube seat quality, increases the defect rate and cost, and restricts production capacity and competitiveness.

[0003] CN207371971U discloses a stamping device for cleaning feed steel strip, including a base, a stamping die located above the base, a thin plate feed port, and a stamped part discharge port. It also includes a dust-collecting fan located on one side of the thin plate feed port. The dust-collecting fan includes a suction port, and the steel strip slides along the suction port. By placing the dust-collecting fan on one side of the thin plate feed port and allowing the steel strip to slide along the suction port, the dust-collecting fan can clean the dust on the surface of the steel strip about to enter the thin plate feed port, improving the cleanliness of the steel strip. Simultaneously, the dust-collecting fan, in contact with the steel strip, can support the steel strip, preventing it from contacting the ground due to its own weight and increasing dust accumulation on its surface. The dust-collecting fan is mounted on a disc-shaped frame, and the steel strip slides circumferentially along the frame, allowing the suction port to better clean the surface of the steel strip during the sliding process between the steel strip and the frame.

[0004] However, due to the lack of a precise and reliable positioning and fixing mechanism, the steel strip is prone to displacement and shaking during the stamping process, resulting in inconsistent quality of the tube seat. This not only makes it difficult to guarantee product consistency, but also may lead to production interruptions due to frequent adjustments to stamping parameters and equipment status, further reducing production efficiency and increasing the difficulty and cost of production management. Summary of the Invention

[0005] To address the problems mentioned in the background section, the present invention provides a tube seat raw material stamping device.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a tube seat raw material stamping equipment, including a frame, a hydraulic cylinder fixed at the top of the frame, a shaping mechanism installed at the top of the frame, a discharge hole opened at the top of the frame, a discharge port opened on the outside of the frame, a lifting mechanism fixed at the top of the frame, a limit mechanism installed at the top of the lifting mechanism, a feeding rack fixed at the top of the frame, a residual material collection box fixed on the outside of the frame, and a control panel fixed on the outside of the frame; The shaping mechanism includes a lower mold, a shim block, and a positioning rod. The lower mold is fixed to the top of the frame. The top of the lower mold is fixed with a shim block and a positioning rod. The top of the lower mold has a mold groove, and one end of the lower mold has an inclined surface. The lifting mechanism includes a base, a first connecting rod, and a first support block. The top of the base is fixed to the top of the frame. The first connecting rod is rotatably connected inside the base. One end of the first connecting rod is hinged to the first support block. The first mounting block is movably connected inside the base.

[0007] Preferably, a piston rod is movably connected inside the lower mold, a support spring is sleeved on the outside of the piston rod, an upper mold is fixed to the top of the piston rod, and a module is fixed to the bottom of the upper mold.

[0008] Preferably, there are four sets of piston rods, which are symmetrically distributed about the central axis of the upper mold. The support spring is used to compress the piston rods and keep them moving upward.

[0009] Preferably, a second connecting rod is rotatably connected to the outside of the first mounting block, a second support block is rotatably connected to one end of the second connecting rod, a servo motor is fixed to the outside of the second support block, a first screw is fixed to the rotating end of the servo motor, a third connecting rod is rotatably connected to the outside of the second support block, a second mounting block is rotatably connected to the top end of the third connecting rod, a fourth connecting rod is rotatably connected to the outside of the first support block, and a top plate is rotatably connected to the top end of the fourth connecting rod. Through the cooperation of multiple sets of connecting rods and driving components, the height of the top plate can be flexibly adjusted. When the servo motor drives the first screw to rotate, the first screw and the first support block are threaded together, causing the first support block to move, which drives the angle of multiple sets of connecting rods such as the first connecting rod and the second connecting rod to change. Then, the top plate is raised and lowered through the fourth connecting rod, the third connecting rod, etc. The first mounting block slides with the base, and the second mounting block slides with the top plate, ensuring stable movement of the connecting rods. This allows the steel strip height to change, ensuring that the guide wheel of the limiting mechanism always effectively limits and guides the steel strip, maintaining it in a suitable stamping position, ensuring stamping stability and accuracy, and improving equipment adaptability and processing quality.

[0010] Preferably, there are two sets of first connecting rods, which are symmetrically distributed about the central axis of the base. The outer wall of the first mounting block is attached to the inner wall of the base, and the first mounting block and the base are slidably connected.

[0011] Preferably, the first screw and the second support block are rotatably connected, the first screw and the first support block are threadedly connected, the outer wall of the second mounting block is attached to the inner wall of the top plate, and the second mounting block and the top plate are slidably connected.

[0012] Preferably, the limiting mechanism includes a second screw, a positioning plate, and a buffer block. The second screw is threaded to the outside of the top plate, and one end of the second screw is rotatably connected to the positioning plate. The buffer block is movably connected inside the positioning plate, and a return spring is fixed to the outside of the buffer block. A guide wheel is rotatably connected inside the buffer block, and a guide groove is provided on the outside of the guide wheel. The second screw is threaded to the top plate and rotatably connected to the positioning plate. The spacing between the two symmetrically arranged second screws and positioning plates can be adjusted to accommodate steel strips of different widths. The buffer block is slidably connected to the positioning plate, and the external return spring keeps it moving outward, providing cushioning when the steel strip deviates and reducing impact damage. The guide wheel inside the buffer block has an annular guide groove. The three sets of equally spaced guide wheels can accurately limit and guide the steel strip, avoiding deviation that could lead to stamping defects and improving product consistency. At the same time, the rotation of the guide wheel can reduce friction and ensure smooth conveying.

[0013] Preferably, two sets of the second screw and the positioning plate are provided, and the second screw and the positioning plate are symmetrically distributed about the central axis of the top plate. Two sets of the buffer blocks are provided, and the buffer blocks are symmetrically distributed about the central axis of the positioning plate.

[0014] Preferably, the outer wall of the buffer block is attached to the inner wall of the positioning plate, the buffer block and the positioning plate are slidably connected, and the return spring is used to squeeze the buffer block and keep it moving outward.

[0015] Preferably, the guide wheels are provided in three sets, and the guide wheels are arranged at equal intervals about the central axis of the positioning plate, and the guide groove is formed in a circular shape.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention, through the cooperation of structures such as a base, a first connecting rod, and a first support block, enables the device to flexibly adjust the height of the limiting mechanism to adapt to changes in the height of the steel strip. The base provides an installation foundation for the lifting mechanism. The first connecting rod and the first support block, in cooperation with other connecting rod structures, change the angle between multiple sets of connecting rods when the servo motor drives the first screw to rotate, thereby adjusting the height of the top plate. This ensures that the guide wheel always effectively limits and guides the steel strip, maintaining the steel strip in a suitable position for stamping and ensuring stamping stability.

[0017] This invention, through the combination of a second screw, a positioning plate, and a buffer block, enables the device to precisely limit and buffer the steel strip. The second screw adjusts the position of the positioning plate to accommodate steel strips of different widths. The buffer block, in conjunction with the return spring, provides cushioning and maintains the position of the guide wheel when the steel strip deviates. The guide groove of the guide wheel precisely guides the steel strip, preventing steel strip deviation from causing stamping defects and improving product consistency.

[0018] This invention, through the combination of a lower mold, a shim block, and a positioning rod, enables the device to precisely stamp and shape steel strips and achieve automatic unloading. The lower mold provides the stamping foundation, and its top mold groove cooperates with the upper mold module to complete the stamping. The shim block creates a height difference, which, combined with the toughness of the steel strip, facilitates the lifting and movement of the shaped tube seat. The positioning rod further guides the steel strip to ensure accurate stamping position. At the same time, the inclined surface and the unloading hole cooperate to achieve automatic discharge of the tube seat, improving processing efficiency and accuracy. Attached Figure Description

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] like Figures 1 to 7 As shown, the present invention provides a tube seat raw material stamping equipment, including a frame 1, a hydraulic cylinder 2 fixed at the top of the frame 1, a shaping mechanism 3 installed at the top of the frame 1, a discharge hole 4 opened at the top of the frame 1, a discharge port 5 opened on the outside of the frame 1, a lifting mechanism 6 fixed at the top of the frame 1, a limit mechanism 7 installed at the top of the lifting mechanism 6, a feeding rack 8 fixed at the top of the frame 1, a residual material collection box 9 fixed on the outside of the frame 1, and a control panel 10 fixed on the outside of the frame 1.

[0023] The above scheme allows for the collection of the stamped tube seat through the unloading hole 4 and its discharge through the outlet 5. The device can be controlled through the control panel 10.

[0024] like Figures 1 to 3 As shown, the shaping mechanism 3 includes a lower mold 301, a shim block 302, and a positioning rod 303. The lower mold 301 is fixed to the top of the frame 1. The shim block 302 is fixed to the top of the lower mold 301. The positioning rod 303 is fixed to the top of the lower mold 301. A mold groove 304 is opened at the top of the lower mold 301. An inclined surface 305 is opened at one end of the lower mold 301. A piston rod 306 is movably connected inside the lower mold 301. A support spring 307 is sleeved on the outside of the piston rod 306. An upper mold 308 is fixed to the top of the piston rod 306. A module 309 is fixed to the bottom of the upper mold 308. There are four sets of piston rods 306. The piston rods 306 are symmetrically distributed about the central axis of the upper mold 308. The support spring 307 is used to squeeze the piston rods 306 and keep them moving upward.

[0025] The above scheme is adopted as follows: the steel strip is guided by the guide wheel 705 and the guide groove 706 through the feeding frame 8 and placed at the top of the pad block 302. The positioning rod 303 further guides the steel strip. The feeding frame 8 conveys the steel strip and moves it. After the steel strip moves to the top of the mold groove 304, the hydraulic cylinder 2 is activated to press down the upper mold 308 and the module 309. Then, the module 309 and the mold groove 304 punch and shape the steel strip. After the punching is completed, the upper mold 308 and the module 309 are reset. The steel strip tube seat after being shaped is lifted by the height difference generated by the pad block 302 and the toughness of the steel strip. At this time, the steel strip continues to move. The shaped steel strip tube seat enters the next process. When the hydraulic cylinder 2 presses and pushes the unprocessed steel strip through the module 309, the shaped steel strip tube seat is cut and discharged into the discharge port 5 through the inclined surface 305 and the discharge hole 4.

[0026] like Figures 1 to 5 As shown, the lifting mechanism 6 includes a base 601, a first connecting rod 602, and a first support block 603. The top of the base 601 is fixed to the top of the frame 1. The first connecting rod 602 is rotatably connected inside the base 601. One end of the first connecting rod 602 is hinged to the first support block 603. The first mounting block 604 is movably connected inside the base 601. There are two sets of the first connecting rod 602, which are symmetrically distributed about the central axis of the base 601. The outer wall of the first mounting block 604 fits against the inner wall of the base 601, and the first mounting block 604 and the base 601 are slidably connected.

[0027] like Figures 1 to 5 As shown, a second connecting rod 605 is rotatably connected to the outside of the first mounting block 604. One end of the second connecting rod 605 is rotatably connected to a second support block 606. A servo motor 607 is fixed to the outside of the second support block 606. A first screw 608 is fixed to the rotating end of the servo motor 607. A third connecting rod 609 is rotatably connected to the outside of the second support block 606. A second mounting block 610 is rotatably connected to the top end of the third connecting rod 609. A fourth connecting rod 611 is rotatably connected to the outside of the first support block 603. A top plate 612 is rotatably connected to the top end of the fourth connecting rod 611. The first screw 608 and the second support block 606 are rotatably connected. The first screw 608 and the first support block 603 are threadedly connected. The outer wall of the second mounting block 610 fits against the inner wall of the top plate 612. The second mounting block 610 and the top plate 612 are slidably connected.

[0028] The above solution involves starting the servo motor 607 to rotate the first screw 608, causing the first screw 608 to move the position of the first support block 603 via its own thread. This movement of the first support block 603 changes the angles between the first connecting rod 602, the second connecting rod 605, the third connecting rod 609, and the fourth connecting rod 611, thereby adjusting the height of the top plate 612. When the guide wheel 705 and guide groove 706 on the top plate 612 limit and guide the steel strip, if the steel strip coil is worn and the contact height between the steel strip coil and the guide wheel 705 changes, the height of the guide wheel 705 and guide groove 706 is adjusted to adapt to the real-time height of the steel strip, thus tensioning the steel strip and maintaining its height at a suitable position for stamping, thereby improving the stamping efficiency of the device. The first mounting block 604 is slidably connected to the base 601, and the second mounting block 610 is slidably connected to the top plate 612, providing a stable trajectory for the rotation of each link, avoiding jamming or offset during angle adjustment, and ensuring smooth and precise lifting of the top plate 612. The coordinated cooperation of multiple sets of links forms a stable support system, which can evenly bear the weight of the top plate 612 and the limiting mechanism 7, reduce the stress load on individual components, reduce equipment wear, and extend the overall service life. The servo motor 607 has high-precision control characteristics, and the rotation amplitude of the first screw 608 can be precisely adjusted through the control panel 10 to achieve fine adjustment of the height of the top plate 612, ensuring that the guide wheel 705 and the steel strip always maintain a suitable contact force, further enhancing the limiting and guiding effect on the steel strip, and maintaining the stability of the stamping process.

[0029] like Figures 1 to 7 As shown, the limiting mechanism 7 includes a second screw 701, a positioning plate 702, and a buffer block 703. The second screw 701 is threadedly connected to the outside of the top plate 612. One end of the second screw 701 is rotatably connected to the positioning plate 702. The buffer block 703 is movably connected inside the positioning plate 702. Two sets of the second screw 701 and the positioning plate 702 are provided, and the second screw 701 and the positioning plate 702 are symmetrically distributed about the central axis of the top plate 612. Two sets of the buffer block 703 are also provided, and the buffer block 703 is symmetrically distributed about the central axis of the positioning plate 702. A return spring 704 is fixed to the outside of the buffer block 703. The outer wall of the buffer block 703 is attached to the inner wall of the positioning plate 702. The buffer block 703 and the positioning plate 702 are slidably connected. The return spring 704 is used to squeeze the buffer block 703 and keep it moving outward. A guide wheel 705 is rotatably connected inside the buffer block 703. A guide groove 706 is opened on the outside of the guide wheel 705. There are three sets of guide wheels 705. The guide wheels 705 are arranged at equal intervals about the central axis of the positioning plate 702. The guide groove 706 is opened in a circular shape.

[0030] The above solution involves rotating two sets of second screws 701 to adjust the positions of two sets of positioning plates 702, ensuring the distance between them allows the steel strip to pass through. The steel strip is then engaged in the guide groove 706 of the guide wheel 705, and guided and conveyed through the guide groove 706. If the steel strip shifts position during transport, the direction of the shift is compressed, and the return spring 704 at this point releases its stored force, allowing the guide wheel 705 and guide groove 706 to maintain their original positions and guide and limit the steel strip. This buffers and guides the steel strip during transport and during stamping, preventing positional shifts in the steel strip that could cause shifts in the stamped product. The rotational characteristics of the guide wheel 705 reduce frictional resistance during transport, making the steel strip move more smoothly. Smooth operation prevents excessive resistance from causing the steel belt to stretch or deform, ensuring the stability of the steel belt conveying. The buffer block 703 is slidably connected to the positioning plate 702, and the return spring 704 always applies an outward force to the buffer block 703, allowing the guide wheel 705 to fit tightly against the steel belt. Even if there are slight differences in the thickness of the steel belt, the buffer structure can adaptively adjust to ensure a continuous and reliable guiding effect. Three sets of equally spaced guide wheels 705 form a multi-support point limit, constraining the steel belt from multiple positions, further reducing the possibility of steel belt deviation and improving the overall guiding accuracy. The annular guide groove 706 is adapted to the shape of the steel belt, which can more accurately hold the edge of the steel belt, preventing the steel belt from moving in the vertical direction, ensuring that the steel belt is in the correct height position during stamping, and improving the dimensional accuracy and consistency of the tube seat stamping.

[0031] The working principle and usage process of this invention are as follows: The steel strip is guided by the guide wheel 705 and the guide groove 706 through the feeding frame 8 and placed at the top of the pad block 302. The positions of the two sets of positioning plates 702 are adjusted by rotating the two sets of second screws 701 so that the distance between the two sets of positioning plates 702 is sufficient for the steel strip to pass through. The steel strip is then inserted into the guide groove 706 of the guide wheel 705 and guided and conveyed through the guide groove 706. When the position of the steel strip deviates during the conveying process, the direction of the deviation is compressed. The return spring 704 at this point stores and releases its energy, so that the guide wheel 705 and the guide groove 706 can maintain their original position to guide and limit the steel strip, thereby buffering and guiding the steel strip during the conveying process and during the stamping process.

[0032] Next, the servo motor 607 is started to drive the first screw 608 to rotate, so that the first screw 608 moves the position of the first support block 603 through its own thread. In turn, the movement of the first support block 603 changes the angle between the first connecting rod 602 and the second connecting rod 605, as well as the third connecting rod 609 and the fourth connecting rod 611, thereby adjusting the height of the top plate 612. When the guide wheel 705 and the guide groove 706 on the top plate 612 limit and guide the steel strip, when the steel strip coil is worn and the contact height between the steel strip coil and the guide wheel 705 changes, the height of the guide wheel 705 and the guide groove 706 is changed to adapt to the real-time height of the steel strip, thereby tensioning the steel strip and keeping its height at a suitable position for stamping, thus improving the stamping efficiency of the device.

[0033] Finally, the feeding rack 8 guides the steel strip through the guide wheel 705 and guide groove 706 to position it at the top of the shim block 302, and further guides the steel strip through the positioning rod 303. The feeding rack 8 then transports the steel strip, causing it to move. After the steel strip moves to the top of the mold groove 304, the hydraulic cylinder 2 is activated to press down the upper mold 308 and module 309, thereby stamping and shaping the steel strip through the module 309 and mold groove 304. After the stamping is completed, the upper mold 308 and module 309 are reset. The shaped steel strip tube seat is lifted by the height difference generated by the shim block 302 and the toughness of the steel strip. At this time, the steel strip continues to move, and the shaped steel strip tube seat enters the next process. When the hydraulic cylinder 2 presses and pushes the unprocessed steel strip through the module 309, the shaped steel strip tube seat is cut, so that it enters the discharge port 5 through the inclined surface 305 and the discharge hole 4 for discharge.
