Description

Technical Field

[0001] This utility model relates to the field of non-standard automated mechanical equipment, specifically to an automatic metal rod forming machine. Background Technology

[0002] In the field of kitchenware accessories, metal brackets, as core structural components supporting food trays and baking pans, are widely used in various kitchen appliances such as household ovens, commercial barbecue grills, and built-in microwave ovens. The core component of these metal brackets, the legs, is often made from shaped metal rods. Depending on the load-bearing requirements of the kitchen equipment and the limitations of installation space, the legs of the metal brackets must have specific structural forms.

[0003] Currently, small and medium-sized enterprises still rely primarily on manual processing. Specifically, operators first place a straight metal rod on a simple stamping die and use a manual wrench or foot-operated punch press to form the central protrusion. The semi-finished product is then transferred to a bending machine, where the metal rod's position is manually adjusted before the bending machine is started to bend both ends. This processing method is extremely inefficient and requires frequent workstation changes and equipment adjustments, making it unsuitable for mass production. Processing accuracy also heavily depends on manual experience, resulting in a high defect rate. Furthermore, it is labor-intensive and poses significant safety risks. Operators must hold the metal rod for extended periods in contact with the stamped and bent parts, increasing the risk of hand injuries due to fatigue or accidents caused by operational errors.

[0004] Therefore, how to overcome the above-mentioned defects and provide an automated metal rod forming machine to improve production efficiency and product qualification rate, and realize the one-time forming of metal rods into metal bracket legs in automated equipment, has become an important issue that needs to be solved by those skilled in the art.

[0015] Compared with the prior art, the beneficial effects of this utility model are: This invention provides a highly automated metal rod forming machine that significantly improves efficiency and processing precision. By integrating all the necessary mechanisms in the processing steps into a single machine, it automates each step, thus achieving full automation of the metal rod forming process. The machine uses a feeding platform to automatically load materials after manual placement.

[0025] First, it should be noted that this equipment is used to process straight metal rods 200 into legs that can be used as kitchen metal supports (see details). Figure 7 ).

[0026] like Figures 1 to 7 As shown, this invention provides an automatic metal rod forming machine, including a frame 100, which includes a mounting platform 101. The frame 100 is used to support and install various components, providing a support frame for easy placement. In specific implementations, the lower end of the frame 100 is connected to rollers to facilitate the movement of the equipment. The mounting platform 101 provides a mounting support surface for various mechanisms on the machine. A material receiving and unloading mechanism 1, a first moving mold mechanism 2 connected to the upper end of the material receiving and unloading mechanism 1, and a rolling mechanism 3 erected above the material receiving and unloading mechanism 1 and the first moving mold mechanism 2 are mounted on the mounting platform 101. A second moving mold mechanism 4 is also mounted on the mounting platform 101, positioned in front of the material receiving and unloading mechanism 1, the first moving mold mechanism 2, and the rolling mechanism 3. A fixed mold structure 6, positioned at the front end of the first moving mold mechanism 2, for closing the mold with the first moving mold mechanism 2, is also mounted on the mounting platform 101. A feeding platform 5 is connected to the rear end of the rolling mechanism 3 for manual material placement and automatic material supply to the subsequent rolling mechanism 3.

[0027] The rolling mechanism 3 is used to transfer the metal rod 200 on the loading platform 5 forward for the receiving and unloading mechanism 1 to pick up. The receiving and unloading mechanism 1 is used to receive the metal rod 200 transported by the rolling mechanism 3 and provide a support platform for the first moving mold mechanism 2 and the second moving mold mechanism 4 during the forming of the metal rod 200. At the same time, the receiving and unloading mechanism 1 can realize the automatic unloading of the metal rod after processing. The first moving mold mechanism 2 and the fixed mold structure 6 cooperate to complete the first forming of the metal rod 200, and the second moving mold mechanism 4 cooperates with the receiving and unloading mechanism 1 to complete the second forming of the metal rod 200. The automatic metal rod forming machine of this invention integrates the original scattered loading, two forming, and unloading processes into an integrated device, realizing fully automated processing and solving the problems of low efficiency and reliance on manual labor in existing technologies; the layout of each mechanism is compact, occupies little space, and is suitable for the site requirements of kitchenware parts production workshops.

[0028] The working principle is as follows: the metal rod 200 is manually placed into the loading platform 5. The metal rod 200 on the loading platform 5 is transferred to the receiving and unloading mechanism 1 via the rolling mechanism 3. The receiving and unloading mechanism 1 moves between the first moving mold mechanism 2 and the fixed mold structure 6 to receive the metal rod 200. After receiving the metal rod 200, the first moving mold mechanism 2 and the fixed mold structure 6 close the mold to complete the first forming. Then the second moving mold mechanism 4 moves to complete the second forming. Finally, the receiving and unloading mechanism 1 resets and retracts, and the metal rod 200 automatically falls to complete one processing cycle.

[0029] It should be further explained that, in specific implementation, this invention uses multiple sensor switches to detect the presence or absence of objects and their positioning, thereby triggering the device's action or changing its state. This is well-known technology in the field, and will not be described in detail for each sensor switch. In specific implementation, those skilled in the art can, based on common knowledge in the field and in conjunction with this invention, set sensor switches in appropriate locations to achieve the linkage of various mechanisms.

[0030] Specifically, refer to Figures 1-4As shown, the rolling mechanism 3 includes symmetrically arranged fixed seats 31, a rotating shaft 32 rotatably connected to the two fixed seats 31, a turntable 33 mounted on the rotating shaft 32 and rotating synchronously with the rotating shaft 32, and a first motor 34 connected to one end of the rotating shaft 32 to drive the rotating shaft 32 to rotate. The turntable 33 is located between the two fixed seats 31, and several receiving grooves 331 for accommodating materials are equidistantly opened on the outer peripheral wall of the turntable 33. The two fixed seats 31 are symmetrically arranged to provide rotational support for the rotating shaft 32; the rotating shaft 32 passes through the two fixed seats 31, driving the turntable 33 to rotate synchronously; the first motor 34 provides driving force for the rotating shaft 32; the receiving grooves 331 on the outer periphery of the turntable 33 are the bearing units for the metal rods, and the material transfer is realized by the rotation of the turntable 33. By setting the receiving grooves 331, the metal rods 200 are accommodated and restricted from falling off during the rotation process, ensuring the stability of the conveying. In specific implementation, the receiving groove 331 is a cylindrical tube with an inclined surface, and the depth of the groove is greater than the diameter of the metal rod 200, so as to better hold the metal rod 200 and facilitate its entry. Intermittent material transfer is achieved through the continuous rotation of the turntable 33, with a stable transfer rhythm and high compatibility with subsequent processing steps. The receiving grooves 331 are equidistantly arranged to ensure that only one metal rod is transferred at a time, avoiding jamming due to multiple materials. In specific implementation, the first motor 34 is a stepper motor, which facilitates precise speed control and adapts to different processing requirements.

[0031] Continue to refer to Figures 1-4 As shown, specifically, a support column 35 is connected between the two fixed seats 31. The rolling mechanism also includes a connecting plate 36 located outside the turntable 33 and between the two fixed seats 31. The support column 35 provides support for the connecting plate 36 and the fixed plate 51, ensuring the stability of their connection. The feeding platform 5 includes fixed plates 51 symmetrically arranged on the left and right sides and connected to the rear end of the connecting plate 36. The inner sidewall of the fixed plate 51 is folded inward to form an inclined plate 511 inclined towards the rolling mechanism 3. A receiving cavity 52 for placing materials is formed between the two inclined plates 511. The connecting plates 36 on both sides and the fixed plates 51 on both sides together form a material transmission channel 7 to guide the metal rod 200 to be automatically fed and provide movement space. A guide rod 53 is connected to the support column 35. The rear end of the guide rod 53 extends into the receiving cavity 52, and the front end extends into the material transmission channel 7 between the fixed plates 51 on both sides. The guide rod 53 is inclined and its inclination angle is the same as the inclination angle of the inclined plate 511. The feeding platform 5 in this case is connected to the rear end of the rolling mechanism 3. Through the cooperation of the guide rod 53 and the inclined plate 511, the automatic feeding is achieved by using the gravity of the metal rod 200 through the inclined setting. No other special mechanism is required, the structure is simple and saves costs.

[0032] Furthermore, the support column 35 has two columns, one in front and one behind. The rear support column 35 passes through and connects to the connecting plates 36 on both sides and the fixing plates 51 on both sides. The front support column 35 passes through and connects to the fixing plates 51 on both sides. The guide rod 53 is connected to the front support column 35 through a detachable first fixing member. Both support columns 35 are provided with detachable second fixing members 54 located on the outside of the fixing plates 51 on both sides. In specific implementation, the first fixing member (not shown in the figure) and the second fixing member 54 have the same structure and are both connected and fixed to the support column 35 by bolts. The detachable setting of the first fixing member facilitates the replacement of the guide rod 53 to adapt to different models of metal rods 200, and also facilitates the replacement of the guide rod 53 when it is damaged or malfunctions. The detachable setting of the second fixing member 54 facilitates the adjustment of the distance between the connecting plates on both sides and the distance between the fixing plates on both sides, so that the rolling mechanism 3 and the feeding platform 5 can be adapted to metal rods of different lengths. The adjustable size of the mechanism is achieved through the detachable second fixing component 54, eliminating the need to replace the entire feeding platform or rolling mechanism, thus reducing equipment modification costs and improving adaptability. Both the first and second fixing components 54 are bolted together, resulting in a simple structure and convenient adjustment. Operators can complete adjustments and maintenance without specialized tools, enhancing the ease of use of the equipment.

[0033] Specifically, refer to Figures 1-3 , Figure 5As shown, the material receiving and unloading mechanism 1 includes a first base 11 that can be slidably connected to the mounting platform 101 and a receiving plate 12 fixedly connected to the first base 11. The front end of the receiving plate 12 extends out of the first base 11 to provide a receiving platform and a processing support platform, facilitating processing by the first moving mold mechanism 2 and the second moving mold mechanism 4, while avoiding interference with the first base 11. A symmetrical first slide rail 13 is provided on the mounting platform 101, and the lower end of the first base 11 is slidably connected to the first slide rail 13 via a first pneumatic slider 16. In specific implementation, the receiving plate 12 is detachably connected to the first base 11 to facilitate the replacement of receiving plates 12 of different sizes and models to adapt to metal rods of different sizes and models, and to facilitate the maintenance of the receiving plate 12. This is why a structure in which the receiving plate 12 is directly slidably connected to the mounting platform 101 is not used. An inclined unloading channel 14 is installed at the lower end of the mounting platform 101, and an unloading hole 1011 communicating with the unloading channel 14 is also provided on the mounting platform 101. The lower end of the first base 11 is connected to the mounting platform 101 via a first cylinder 15 that can extend and retract forward and backward. Two first cylinders 15 are symmetrically arranged on the left and right sides. When the first cylinder 15 drives the first base 11 to slide the receiving plate 12 backward to reset, because the receiving plate 12 lacks a structure to limit the processed metal rod 200, the metal rod 200 moves forward relative to the receiving plate 12 due to the inertia of the reset, automatically falling into the discharge hole 1011 and flowing out from the discharge channel 14. The first pneumatic slider 16 used in this invention has a pneumatic locking function that can rigidly lock the slider and the slide rail after sliding into position, avoiding minor displacement caused by external forces and improving positioning accuracy; the pneumatic buffering function forms a flexible damping force during the start-stop phase, significantly reducing impact and improving movement stability.

[0034] Continue to refer to Figures 1-3 , Figure 5 As shown, specifically, the first moving mold mechanism 2 includes a fixed bracket 21 mounted on the mounting platform 101, a second cylinder 22 mounted on the fixed bracket 21, and a first mold 23 connected to the front end of the second cylinder 22. The fixed bracket 21 provides mounting support for the second cylinder 22, ensuring the stability of the second cylinder 22 installation. The second cylinder 22 is the power source for the first mold 23, driving the first mold 23 to move. The first mold 23 is slidably connected to the receiving plate 12, which has a groove 121. The lower end of the first mold 23 has a protrusion 231 slidably connected to the groove 121. The groove 121 of the receiving plate 12 cooperates with the protrusion 231 of the first mold 23 to provide sliding guidance for the first mold 23, ensuring mold closing accuracy. In specific implementation, the first mold 23, the second cylinder 22, and the receiving plate 12 are detachably connected to facilitate disassembly and replacement, adapting to metal rods 200 with different processing shape requirements.

[0035] Continue to refer to Figures 1-3 , Figure 5As shown, specifically, the fixed mold structure 6 includes a fixed base 61 mounted on the mounting platform 101 and a second mold 62 mounted on the fixed base 61 for closing with the first mold 23. The fixed base 61 is used to connect and fix the second mold 62, while providing it with a suitable height. In specific implementations, the fixed base 61 is detachably connected to the mounting platform 101 for easy disassembly and replacement to adapt to metal rods 200 with different processing shape requirements. The fixed mold structure 6, in conjunction with the first moving mold mechanism 2, processes the metal rod 200 into the required shape.

[0036] Continue to refer to Figures 1-3 , Figure 5 , Figure 7 As shown, the second mold 62 includes a triangular protrusion 621 disposed at its rear end, and the first mold 23 has a V-shaped groove 232 at its front end for the triangular protrusion 621 to engage for mold closing. That is to say, the triangular protrusion 621 of the second mold 62 and the V-shaped groove 232 of the first mold 23 are complementary molding structures, and their shapes and sizes are perfectly matched. The angle and height of the triangular protrusion 621 are consistent with the angle and depth of the V-shaped groove 232. When the mold is closed, the triangular protrusion 621 engages with the V-shaped groove 232, and the metal rod 200 is squeezed between the two. Through the cooperation of the two, the middle part of the metal rod 200 is processed into a rearward protruding triangle 301.

[0037] Specifically, refer to Figures 1-3 , Figure 6 , Figure 7 As shown, the second moving mold mechanism 4 includes a support frame 41 mounted on the mounting platform 101, a second slide rail 42 mounted on the support frame 41, a base plate 44 slidably connected to the second slide rail 42 via a second pneumatic slider 43, a third cylinder 45 mounted on the support frame 41, and a pressure rod 46 connected to the lower end of the base plate 44, which cooperates with the material receiving and unloading mechanism 1 to bend both ends of the material downwards. The support frame 41 serves as the mounting base for the second slide rail 42 and the third cylinder 45, providing the mounting position and support. The lower end of the third cylinder 45 is connected to the base plate 44 to drive the base plate 44 to slide up and down. Two pressure rods 46 are symmetrically arranged on the left and right sides to bend both ends of the metal rod 200 downwards. The lower end of the pressure rod 46 extends outside the base plate 44 to prevent the base plate 44 from interfering with other mechanisms when it moves downwards to perform the bending operation. The support frame 41 includes two vertically arranged vertical tubes 411, and a second slide rail 42 is vertically mounted on the vertical tubes 411. A third cylinder 45 drives the base plate 44 downwards, thereby causing the pressure rod 46 to move downwards. The pressure rod 46 presses down on both ends of the metal rod 200, which has been initially formed in the middle, and bends them downwards to form support legs 302, completing the second and final processing. The finished metal rod support legs are approximately M-shaped and are used as support legs on both sides of the kitchen metal bracket.

[0038] The working principle of this case will be described below, based on the full text: The operator places the metal rod 200 into the receiving cavity 52 of the loading platform 5. Under the action of gravity, the metal rod 200 slides along the inclined plate 511 of the fixed plate 51 and the guide rod 53 into the material transmission channel 7 enclosed by the connecting plate 36 and the fixed plate 51, and finally abuts against the outside of the turntable 33 of the rolling mechanism 3. When the receiving plate 12 of the receiving and unloading mechanism 1 is in the receiving position, the first motor 34 of the rolling mechanism 3 drives the rotating shaft 32 to drive the turntable 33 to rotate. The receiving groove 331 on the outer periphery of the turntable 33 rotates with the turntable 33 to receive the metal rod 200 in the material transmission channel 7, and then transfers the metal rod 200 to the receiving plate 12, and the rolling mechanism 3 stops operating. After the receiving plate 12 receives the metal rod 200, the first cylinder 15 drives the first base 11 to slide forward along the first slide rail 13 of the mounting platform 101, and the first pneumatic slider 16 at the lower end of the first base 11 slides synchronously along the first slide rail 13. When the metal rod 200 moves between the first mold 23 of the first moving mold mechanism 2 and the second mold 62 of the fixed mold structure 6, the first pneumatic slider 16 locks and fixes the position of the first base 11. Then, the second cylinder 22 of the first moving mold mechanism 2 pushes the first mold 23 to slide forward along the slide groove 121 of the receiving plate 12, so that the V-groove 232 of the first mold 23 engages with the triangular protrusion 621 of the second mold 62, and the middle part of the metal rod 200 is processed into a triangular protrusion 301. Afterwards, the third cylinder 45 of the second moving mold mechanism 4 drives the base plate 44 to slide downward along the second slide rail 42 of the support frame 41. The second pneumatic sliders 43 on both sides of the base plate 44 slide synchronously along the second slide rail 42, driving the pressure rod 46 to bend the two ends of the metal rod 200 downward into support feet 302. After the secondary forming is completed, the pressure rod 46 is reset under the drive of the third cylinder 45, the first mold 23 is reset under the drive of the second cylinder 22, and the first pneumatic slider 16 is unlocked. Finally, the first cylinder 15 drives the receiving plate 12 to reset backward. The processed metal rod 200 falls from the unloading hole 1011 of the mounting table 101 into the unloading channel 14 and slides out under the action of inertia. The receiving plate 12 returns to the receiving station and waits for the next processing cycle.

[0039] As stated above, this case protects an automatic metal rod forming machine, and all technical solutions that are the same as or similar to this case should be considered to fall within the scope of protection of this case.
