Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy claw clamping nut production technology, and in particular to a powder metallurgy claw clamping nut flipping and conveying device. Background Technology

[0002] Powder metallurgy technology is widely used in the production of various structural components and fasteners due to its advantages such as high material utilization, high production efficiency, and the ability to mass-produce complex-shaped parts. Claw-type clamping nuts are a typical powder metallurgy product, typically featuring multiple elastic claws at one end for gripping and securing connected parts, while the other end has a standard nut structure.

[0003] On automated production lines, after the claw-type clamping nut is ejected from the forming mold, its orientation is usually with the claws facing downwards. This is because, during pressing and forming, the mold is designed with the claws facing downwards to facilitate demolding and ensure uniform part density. Placing the claws downwards results in a small contact area between the part and the conveyor belt or material channel, and a high center of gravity for the part. This makes it extremely prone to tipping or jamming during transport, easily causing collisions and friction that can deform or damage the part, seriously affecting product quality and performance.

[0004] Therefore, there is an urgent need for a powder metallurgy claw-type clamping nut flipping conveyor that can reliably receive parts after demolding and efficiently flip the parts, ensuring that the parts smoothly enter the next process with the "claws facing up" posture, guaranteeing the reliability and continuity of production, and protecting the parts from damage to the greatest extent. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a powder metallurgy claw-type clamping nut flipping and conveying device.

[0006] This utility model is achieved through the following technical solution: a powder metallurgy claw-type clamping nut flipping and conveying device is provided, including a receiving groove installed on one side of the forming worktable and inclined, and a flipping mechanism located above the receiving groove for picking up workpieces on the forming worktable and flipping the workpieces before placing them into the receiving groove; the flipping mechanism includes a rotary clamping cylinder that can move horizontally and vertically, a horizontal drive component that drives the rotary clamping cylinder to move horizontally, and a vertical drive component that drives the rotary clamping cylinder to move vertically, wherein the rotary clamping cylinder can clamp the workpiece and flip it 180°.

[0007] Preferably, a belt conveyor is installed below the receiving trough. The belt conveyor is used to receive workpieces that slide down from the receiving trough.

[0008] Preferably, the receiving trough forms an angle of 10°-20° with the horizontal plane, allowing the workpiece to slide smoothly and stably onto the belt conveyor.

[0009] Preferably, the vertical driving component is a vertical cylinder, the horizontal driving component is a horizontal cylinder, the cylinder body of the vertical cylinder is mounted on a fixed plate, the fixed plate is connected to the forming worktable through a support frame, the cylinder body of the horizontal cylinder is connected to the piston rod of the vertical cylinder, and the rotary clamping cylinder is mounted on the end of the piston rod of the horizontal cylinder.

[0010] Preferably, the support frame includes two crossbeams connected to the forming worktable. One end of each crossbeam is fixed to the forming worktable by bolts, and the other end is fixed to the fixing plate by a column.

[0011] Preferably, a lifting plate is installed at the end of the piston rod of the vertical cylinder, and the cylinder body of the horizontal cylinder is installed on the lifting plate via a connecting block.

[0012] Preferably, to ensure stable vertical movement of the lifting plate, a guide plate is fixed to the lifting plate, and the guide plate is slidably connected to the fixed plate. A vertical slide rail is provided on the fixed plate, and a slider is fixed on the guide plate. The slider is installed within the slide rail and can move within the slide rail.

[0013] Preferably, a mounting plate is fixed to the end of the piston rod of the transverse cylinder, and the rotary clamping cylinder is fixed to the mounting plate.

[0014] Preferably, in order to ensure the stable horizontal movement of the rotary clamping cylinder, slide rods parallel to the horizontal cylinder are respectively provided on both sides of the horizontal cylinder. The slide rods are slidably connected to the bottom of the lifting plate, one end of the two slide rods is fixed to the mounting plate, and the other end of the two slide rods are fixed to each other through a connecting rod.

[0015] Preferably, a slide rail for sliding the slide rod is installed at the bottom of the lifting plate, and the slide rod is installed in the slide rail and can move along the slide rail.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. This utility model enables the workpiece to be flipped up in a timely and accurate manner after molding and demolding, so that the claw clamping nut claws face upwards before being transported. This avoids the tipping or jamming caused by the claw clamping nut claws facing downwards, prevents workpiece damage, ensures product quality and performance, and ensures that the workpiece enters the next process smoothly with the claws facing upwards, thus ensuring the reliability and continuity of production.

[0018] 2. This utility model creatively installs a flipping mechanism at the discharge end of the forming worktable. After the workpiece is demolded, it can be flipped quickly and efficiently. After flipping, it falls into the receiving trough, so that the workpiece can be stably and smoothly conveyed to the belt conveyor. The flipping and conveying process has high reliability and strong stability, which fully guarantees the stable conveying of the product. Attached Figure Description

[0025] To clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0026] like Figure 1-4 As shown, this utility model includes a receiving groove 2 installed on one side of the forming workbench 1 and inclined, and a flipping mechanism located above the receiving groove 2 for picking up workpieces on the forming workbench 1 and flipping the workpieces and placing them into the receiving groove 2. A belt conveyor 3 is provided below the receiving groove 2. The belt conveyor 3 is used to receive workpieces that slide down from the receiving groove 2. The belt conveyor 3 is an existing structure, and its structure and working principle will not be described in detail here.

[0027] In this embodiment, the receiving trough 2 forms an angle of 10°-20° with the horizontal plane, so that the workpiece can slide smoothly and stably onto the belt conveyor 3.

[0028] The flipping mechanism includes a rotary clamping cylinder 4 that can move horizontally and vertically, a horizontal drive component that drives the rotary clamping cylinder 4 to move horizontally, and a vertical drive component that drives the rotary clamping cylinder 4 to move vertically. The rotary clamping cylinder 4 can clamp the workpiece and flip it 180°.

[0029] The vertical drive component is a vertical cylinder 5, and the horizontal drive component is a horizontal cylinder 6. The cylinder body of the vertical cylinder 5 is mounted on a fixed plate 7, which is connected to the forming worktable 1 via a support frame. The cylinder body of the horizontal cylinder 6 is connected to the piston rod of the vertical cylinder 5, and a rotary clamping cylinder 4 is mounted on the end of the piston rod of the horizontal cylinder 6. The support frame includes two crossbeams 8 connected to the forming worktable 1. One end of each crossbeam 8 is fixed to the forming worktable 1 by bolts, and the other end is fixed to the fixed plate 7 via a column 9.

[0030] In this embodiment, a lifting plate 10 is installed at the end of the piston rod of the vertical cylinder 5, and the cylinder body of the horizontal cylinder 6 is installed on the lifting plate 10 via a connecting block 11. To ensure stable up-and-down movement of the lifting plate 10, a guide plate 12 is fixed on the lifting plate 10, and the guide plate 12 is slidably connected to a fixed plate 7. A vertical slide rail 13 is provided on the fixed plate 7, and a slider 14 is fixed on the guide plate 12. The slider 14 is installed within the slide rail 13 and can move within the slide rail 13.

[0031] A mounting plate 15 is fixed to the end of the piston rod of the transverse cylinder 6, and the rotary clamping cylinder 4 is fixed to the mounting plate 15. To ensure stable horizontal movement of the rotary clamping cylinder 4, sliding rods 16 parallel to the transverse cylinder 6 are respectively provided on both sides of the transverse cylinder 6. The sliding rods 16 are slidably connected to the bottom of the lifting plate 10, with one end of each sliding rod 16 fixed to the mounting plate 15, and the other ends of each sliding rod 16 fixed to each other via a connecting rod 17. A slide rail 18 for sliding the sliding rods 16 is installed at the bottom of the lifting plate 10, and the sliding rods 16 are installed within the slide rail 18 and can move along the slide rail 18.

[0032] The rotary clamping cylinder 4 includes a cylinder body, a cylinder rotating disk mounted in front of the cylinder body, and grippers mounted on the cylinder rotating disk. The rotary gripper cylinder integrates rotary clamping functions. The specific structure and working principle of the rotary clamping cylinder 4 are existing technologies and will not be described in detail here.

[0033] In actual operation, after the workpiece is formed and demolded on the forming worktable 1, the transverse cylinder 6 of the flipping mechanism controls the piston rod to extend, causing the rotary clamping cylinder 4 to move to the forming worktable 1 (e.g., Figure 1 , 2 As shown), the rotary clamping cylinder 4 controls the jaws to clamp the workpiece, then the horizontal cylinder 6 controls the piston rod to retract, causing the rotary clamping cylinder 4 and the workpiece to move out of the forming worktable 1. Next, the cylinder rotating plate of the rotary clamping cylinder 4 rotates 180° to flip the workpiece (the jaws of the jaw clamping nut face upwards after flipping). The vertical cylinder 5 controls the piston rod to extend, causing the horizontal cylinder 6, the rotary clamping cylinder 4, and the workpiece to move downwards as a whole (as shown). Figure 3 , 4 As shown), at this time, the grippers of the rotating clamping cylinder 4 open, allowing the workpiece to fall into the receiving groove 2. The workpiece slides down the receiving groove 2 to the belt conveyor 3, and is then transported to the next process by the belt conveyor 3.

[0034] This invention enables the workpiece to be flipped up promptly and accurately after molding, ensuring that the claw clamping nut's claws face upwards before being transported. This avoids tipping or jamming caused by the claw clamping nut's claws facing downwards, preventing workpiece damage, ensuring product quality and performance, and ensuring that the workpiece smoothly enters the next process with the claws facing upwards, thus guaranteeing the reliability and continuity of production.

[0035] This invention creatively installs a flipping mechanism at the discharge end of the forming workbench 1. After the workpiece is demolded, it can be flipped quickly and efficiently. After flipping, it falls into the receiving trough 2, so that the workpiece can be stably and smoothly conveyed to the belt conveyor 3. The flipping and conveying process has high reliability and strong stability, which fully guarantees the stable conveying of the product.
