Description

Technical Field

[0001] This invention relates to the field of roller chain plate stamping, and particularly to a continuous blanking fixture for roller chain plate stamping. Background Technology

[0002] Roller chain plates are key components of roller chains, consisting of inner and outer plates, both made of metal and shaped like an "8" to balance tensile strength. They are connected to sleeves and pins via interference fits, forming the rigid structure of the chain, supporting the rollers and transmitting power. During production, roller chain plates are formed through stamping, followed by heat treatment to enhance their hardness and wear resistance, then surface treatments such as polishing and shot peening to improve performance. Finally, they undergo rigorous quality inspection before entering the assembly stage.

[0003] The roller chain plate stamping process employs automated production line technology, using a press and progressive dies to achieve automatic feeding and continuous stamping of coiled steel strip. Guide pillars and bushings within the die ensure stamping accuracy, and the punch and die are made of cemented carbide. After stamping, a robotic arm or suction cup device automatically removes the chain plate, while the sheet metal is precisely stepped forward by a servo motor, achieving fully automated production.

[0004] The shortcomings of the existing technical solutions are as follows: in the automatic removal stage of roller chain plate stamping, the robotic arm or suction cup needs to frequently reciprocate, pick up and put down, while strictly synchronizing with the stamping rhythm, resulting in low overall efficiency. This impact on efficiency is particularly pronounced for robotic arm structures that rely on high-precision sensors and vision systems in the alignment stage. Summary of the Invention

[0005] This invention provides a continuous blanking fixture for stamping roller chain plates, which can solve the problem of low efficiency when transferring roller chain plates by robotic arms or suction cups in the prior art.

[0006] A continuous blanking fixture for roller chain plates includes a base disposed below a stamping head. A die cavity aligned with and fitted to the stamping head is fixedly mounted on the base. The base has symmetrically arranged grooves on both sides for guiding the roller chain plates. A material conveying mechanism for moving the roller chain plates and a drive mechanism for moving the material conveying mechanism are slidably fitted on the base. The material conveying mechanism includes a movable frame cooperating with the drive mechanism. The drive mechanism can drive the movable frame to move along the extension direction of the grooves. Automatic telescopic rods are fitted on both sides of the movable frame. A push plate is fixedly mounted at the output end of each set of automatic telescopic rods. The automatic telescopic rods can drive the push plate downwards, facilitating the movement of the roller chain plates located inside the grooves. A pickup assembly is fitted in the middle of the movable frame, used to transfer the roller chain plates from the die cavity into the grooves.

[0007] As a further aspect of the present invention: the picking component includes an electromagnetic telescopic device that is configured to cooperate on the movable frame, and an electromagnetic plate is fixedly provided at the extension end of the electromagnetic telescopic device for magnetically attracting the roller chain plate.

[0008] As a further aspect of the present invention: a notch is provided on one side of the push plate to match the shape of the end of the roller chain plate.

[0009] As a further aspect of the present invention: scanning mechanisms are symmetrically arranged on both sides of the base to determine whether the shape of the roller chain plate is qualified.

[0010] As a further aspect of the present invention: the width of the bottom of the chute is the same as the width of the roller chain plate, and the roller chain plate can slide at the bottom of the chute.

[0011] As a further aspect of the present invention: the scanning mechanism includes a support frame fixedly mounted on both sides of the base, an industrial 3D scanner fixedly mounted on the support frame, and the output end of the industrial 3D scanner is located directly above the slide groove.

[0012] As a further embodiment of the present invention: the driving mechanism includes multiple sets of transmission wheels rotatably disposed inside the base, the multiple sets of transmission wheels being symmetrically distributed on the front and rear sides, and each set of transmission wheels on the same side being fitted with a transmission belt, a connecting block being fixedly disposed on the transmission belt, the connecting block being detachably and fixedly connected to the movable frame, a transmission shaft being coaxially and fixedly disposed between at least two sets of transmission wheels whose front and rear positions correspond to each other, a motor being fixedly disposed inside the base, and the output end of the motor being coaxially and fixedly connected to a set of transmission wheels.

[0013] As a further aspect of the present invention: a guide frame is fixedly provided on the base, and the guide frame is slidably engaged with the connecting block.

[0014] As a further aspect of the present invention: a first connecting plate is fixedly mounted on the mobile frame, and the electromagnetic telescopic device is fixedly connected to the first connecting plate.

[0015] As a further aspect of the present invention: a second connecting plate is fixedly installed on the mobile frame, and the automatic telescopic rod is fixedly connected to the second connecting plate.

[0016] The beneficial effects of this invention are: 1. In use, the movable frame, in conjunction with the drive mechanism, moves along the extension direction of the chute under drive. Automatic telescopic rods on both sides drive push plates, whose notches fit the ends of the chain plates, allowing for precise entry into the chute to push the chain plates. The central electromagnetic telescopic device, in conjunction with the electromagnetic plate, picks up the chain plate when the movable frame reaches the top of the die, then releases it above the chute. This structure enables the chain plate to be transported from the die to the chute, and then out of the chute into the carrying box, performing a continuous and efficient reciprocating process. This avoids the cumbersome transfer methods of robotic arms or suction cups, improving the chain plate transfer efficiency.

[0017] 2. In use, the support frame is fixed on both sides of the machine base, providing stable support for the industrial 3D scanner and positioning its output end directly above the slide groove. During the reciprocating transport of the roller chain plates, as the chain plates move along the slide groove under the action of the push plate, the industrial 3D scanner can sequentially detect the surface curvature of the chain plates. Based on the detection results, defective products can be identified and eliminated in a timely manner, effectively reducing the defect rate of the output products. Attached Figure Description

Detailed Implementation

[0020] The specific embodiments of the present invention will be described in detail below, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0021] like Figures 1 to 4As shown in the figure, an embodiment of the present invention provides a continuous blanking fixture for stamping roller chain plates, including a base 1 disposed below a stamping head 2, and a die 3 fixedly disposed on the base 1 and aligned with the stamping head 2. In actual use, the coiled steel strip is automatically fed, and during the feeding process, the coiled steel strip passes through the upper part of the die 3 and approaches the position. At this time, the stamping head 2 performs a reciprocating lifting motion, accurately stamping the roller chain plate from the material plate on the die 3, and the stamped roller chain plate is located inside the die 3. The base 1 has symmetrically provided grooves 101 on both sides for guiding the roller chain plate. The design width of the bottom of the groove 101 is exactly the same as the width of the roller chain plate, so that the roller chain plate can slide smoothly at the bottom of the groove 101. The base 1 is also slidably fitted with a material conveying mechanism 4 for driving the movement of the roller chain plate, and a drive mechanism 6 for driving the movement of the material conveying mechanism 4.

[0022] The material conveying mechanism 4 includes a movable frame 401 that cooperates with the drive mechanism 6, such as... Figure 2 , Figure 4 As shown, the drive mechanism 6 has the ability to move the movable frame 401 along the extension direction of the slide groove 101. Automatic telescopic rods 402 are fitted on both sides of the movable frame 401. Each set of automatic telescopic rods 402 has a push plate 4021 fixedly installed at its output end. One side of the push plate 4021 has a notch that matches the shape of the end of the roller chain plate. In actual operation, the automatic telescopic rods 402 can drive the push plate 4021 downwards, allowing it to enter the slide groove 101. Subsequently, the drive mechanism 6 drives the movable frame 401 to move, thereby pushing the roller chain plate located inside the slide groove 101 to move.

[0023] An electromagnetic telescopic device 403 is installed in the middle of the movable frame 401. An electromagnetic plate 404 is fixedly installed at the extension end of the electromagnetic telescopic device 403, which is used to magnetically attract the roller chain plate. When the movable frame 401 is brought to the top of the die 3 by the drive mechanism 6, the electromagnetic telescopic device 403 is activated, which drives the electromagnetic plate 404 to approach the roller chain plate, thereby picking up the roller chain plate from the die 3. Then the electromagnetic telescopic device 403 retracts, and the roller chain plate is separated from the die 3 and the rolled steel strip under the action of the electromagnetic telescopic device 403. At this time, the drive mechanism 6 drives the movable frame 401 to move, thereby sending the roller chain plate to the top of the side slide groove 101. Then the electromagnetic plate 404 is de-energized, and the roller chain plate, which has lost its magnetism, will fall into the slide groove 101. While the drive mechanism 6 drives the moving frame 401 to move to one side, the automatic telescopic rod 402 drives the push plate 4021 on the corresponding side to enter the slide 101, pushing the roller chain plate that was previously sent into the slide 101 out of the slide 101, and finally the roller chain plate detaches from the slide 101 and falls into the carrying box.

[0024] During the stamping process of the roller chain plate, the coiled steel strip is relatively soft and easily deformed by external forces. This can easily lead to bending of the roller chain plate surface, resulting in defective products. To effectively reduce the defect rate of the output products, scanning mechanisms 5 are symmetrically arranged on both sides of the machine base 1. Their main function is to determine whether the shape of the roller chain plate is up to standard. The scanning mechanism 5 includes a support frame 501 fixedly mounted on both sides of the machine base 1. An industrial 3D scanner 502 is fixedly mounted on the support frame 501, and the output end of the industrial 3D scanner 502 is located directly above the slide groove 101. When the roller chain plate moves along the slide groove 101 under the action of the push plate 4021, the industrial 3D scanner 502 can sequentially detect the curvature of the roller chain plate surface in the slide groove 101, thereby promptly eliminating defective products.

[0025] Robotic arms or hydraulic push devices are provided on both sides of the base 1 as receiving devices. The output end of the robotic arm or hydraulic push device is provided with a deflecting guide rail. When the industrial 3D scanner 502 detects defective products, it will drive the deflecting guide rail to dock with the end of the chute 101, thereby guiding the roller chain plate to the corresponding dropping area, achieving the effect of automatically distinguishing and picking out defective products.

[0026] The drive mechanism 6 includes four sets of transmission wheels 602 rotatably mounted inside the base 1. The four sets of transmission wheels 602 are symmetrically distributed on the front and rear sides. Each pair of transmission wheels 602 on the same side is fitted with a transmission belt 603, preferably a synchronous belt. A connecting block 604 is fixedly mounted on each transmission belt 603, and the connecting block 604 is detachably and fixedly connected to the movable frame 401. A transmission shaft 605 is coaxially fixed between the two sets of transmission wheels 602. A motor 601 is fixedly mounted inside the base 1, and the output end of the motor 601 is coaxially and fixedly connected to one set of transmission wheels 602. A guide frame 606 is fixedly mounted on the base 1, and the guide frame 606 slides in engagement with the connecting block 604. When the movable frame 401 needs to be driven, the motor 601 drives the transmission wheels 602 to rotate, the transmission wheels 602 drive the transmission belt 603 to move, and the transmission belt 603 drives the movable frame 401 to move through the connecting block 604.

[0027] In addition, a first connecting plate 405 and a second connecting plate 406 are fixedly installed on the mobile frame 401, the electromagnetic telescopic device 403 is fixedly connected to the first connecting plate 405, and the automatic telescopic rod 402 is fixedly connected to the second connecting plate 406.

[0028] Working principle: In actual use, the coiled steel strip is automatically fed. During the feeding process, the coiled steel strip passes through the upper part of the die 3 and approaches the position. The stamping head 2 performs a reciprocating lifting motion, accurately stamping the roller chain plate from the material plate on the die 3. The stamped roller chain plate is located inside the die 3.

[0029] When the moving frame 401 is brought to the top of the die 3 by the drive mechanism 6, the electromagnetic telescopic device 403 is activated, driving the electromagnetic plate 404 to approach the roller chain plate, using magnetic attraction to pick up the roller chain plate from the die 3. Subsequently, the electromagnetic telescopic device 403 retracts, and the roller chain plate disengages from the die 3 and the coiled steel strip under the action of the electromagnetic telescopic device 403. The drive mechanism 6 drives the moving frame 401 to move, sending the roller chain plate above the side slide 101. After reaching the designated position, the electromagnetic plate 404 is de-energized, and the demagnetized roller chain plate falls into the slide 101.

[0030] Meanwhile, as the drive mechanism 6 moves the movable frame 401 to one side, the automatic telescopic rod 402 moves the corresponding push plate 4021 downward into the slide groove 101, pushing the roller chain plate that was previously placed into the slide groove 101 out of the slide groove 101. Finally, the roller chain plate detaches from the slide groove 101 and falls into the carrying box. Then, the automatic telescopic rod 402 moves the corresponding push plate 4021 back to its original position to avoid touching the roller chain plate that was just placed in.

[0031] When the roller chain plate moves along the slide 101 under the action of the push plate 4021, the industrial 3D scanner 502 set on the machine base 1 starts to detect the curvature of the roller chain plate surface in the slide 101 in sequence. Based on the detection results, defective products are eliminated in time, thereby effectively reducing the defect rate of output products.

[0032] After the roller chain plate on one side is transported, the drive mechanism 6 moves the moving frame 401 to the other side. Then, when the electromagnetic plate 404 is brought back to the top of the die 3 by the drive mechanism 6, the electromagnetic telescopic device 403 is activated, moving the electromagnetic plate 404 close to the roller chain plate and using magnetic attraction to pick up the roller chain plate from the die 3. Subsequently, the electromagnetic telescopic device 403 retracts, and the roller chain plate disengages from the die 3 and the coiled steel strip under the action of the electromagnetic telescopic device 403. The drive mechanism 6 moves the moving frame 401, sending the roller chain plate to the top of the chute 101 on the other side. After reaching the designated position, the electromagnetic plate 404 is de-energized, and the demagnetized roller chain plate falls into the chute 101.

[0033] During the process of the drive mechanism 6 driving the moving frame 401 to one side, the automatic telescopic rod 402 drives the push plate 4021 on the corresponding side to move downward into the slide groove 101. This step is the same as the above and will not be repeated here.

[0034] As the main protected content of this patent, the movable frame 401 cooperates with the drive mechanism 6 and can move along the extension direction of the slide 101 under drive. The automatic telescopic rods 402 on both sides drive the push plate 4021, whose notches are adapted to the ends of the chain plates, allowing precise entry into the slide 101 to push the chain plates. The electromagnetic telescopic device 403 in the middle cooperates with the electromagnetic plate 404 to pick up the chain plates when the movable frame 401 reaches the top of the die 3, and then delivers them above the slide 101 for release. This structure realizes the continuous stamping and unloading of the roller chain plates by the movable frame 401, from the die 3 to the slide 101, and then out of the slide 101 into the carrying box. The process is smooth and efficient, avoiding the cumbersome transfer of robotic arms or suction cups, and improving the chain plate transfer efficiency.

[0035] Industrial 3D scanners 502 are installed on both sides of the base 1, with their output ends positioned directly above the slide groove 101. During the reciprocating transport of the roller chain plates, as the chain plates move along the slide groove 101 under the action of the push plate 4021, the industrial 3D scanners 502 can sequentially detect the surface curvature of the chain plates. Based on the detection results, defective products can be identified and eliminated in a timely manner, effectively reducing the defect rate of the output products.

[0036] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
