[0007] After adopting the present invention, the workpiece clamping and circulation device can simultaneously and controlledly grab the three corrugated tubes distributed at the output end of the feeding device, the first joint welding station, and the second joint welding station, and then shift them to the first joint welding station, the second joint welding station, and the cooling device to fall down, thereby realizing the automatic circulation of the metal hose between the various processes in the manufacturing process, significantly improving production efficiency, and helping to ensure quality. When the length of the metal hose is short, after the first joint welding is completed at one end, the position conversion device can be controlled first, and the metal hose with one end welded can be lifted by the claws, and then driven by the servo motor to move with the slide to the position where the unwelded end is aligned with the second joint welding station; then the workpiece clamping and circulation device is used to complete the circulation between the stations. It can be seen that the present invention organically combines the workpiece clamping and circulation device with the position conversion device, is suitable for metal hoses of various lengths, and has good adaptability.

[0009] A further improvement of the present invention is that the bottom surface of each profile suspension rod is provided with six pneumatic opening and closing clamping jaws which are distributed at intervals, and each clamping jaw is driven by a corresponding opening and closing cylinder.

[0010] A further improvement of the present invention is that two rails and slides on both sides respectively forming moving pairs with the corresponding rails are installed on the bottom plate, and the middle part of the slide is connected to a transmission belt driven by a servo motor located between the rails on both sides.

The frame structure bracket 7 is equipped with a workpiece clamping and circulation device 6 that can be shifted above the output end of the feeding device 1, the first joint welding station 2, the second joint welding station 3 and the cooling device 4. A position conversion device 5 is arranged on the workbench between the first joint welding station 2 and the second joint welding station 3.

[0022] The specific structure of the workpiece clamping and circulation device 6 is as follows: Figure 4As shown, the top plate assembly 6.1 includes a horizontal moving pair formed by a servo drive mechanism 601 and a guide rail on a bracket 7, so that the top plate assembly 6.1 can move along the guide rail on the bracket under the drive of the servo drive mechanism. The lower surface of the top plate assembly 6.1 is equipped with three horizontal profile suspension rods 6.2 driven and connected by lifting cylinders 6023. More specifically, the lower surface of the top plate assembly 6.1 is equipped with three groups of lifting cylinders 6023, the lower ends of the cylinder bodies of the lifting cylinders 6023 are connected to the fixed plate 6.4, the profile suspension rods 6.2 are connected to the telescopic ends of the corresponding groups of lifting cylinders 6023 through the connecting plate 6.3, the two ends of the fixing plate 6.4 are respectively fixedly connected to the sliding sleeves 6.5, and the two ends of the connecting plate 6.3 are respectively fixedly connected to the vertical sliding columns 6.6 passing through the corresponding sliding sleeves 6.5. The length direction of each profile suspension rod 6.2 is perpendicular to the workpiece flow direction, and six pneumatic opening and closing clamps 6022 are installed on the bottom surface thereof, and each clamp 6022 is driven by a corresponding opening and closing cylinder 6021. The specific structure of the pneumatic opening and closing clamp 6022 can be found in the Chinese patent document with application number 202022164048.X or 201520140541.4, which will not be described in detail.

[0023] The specific structure of the position conversion device 5 is as follows: Figure 5 As shown, two rails 5.2 perpendicular to the workpiece flow direction and slides 5.3 on both sides are installed on the bottom plate 5.1, which form a moving pair with the corresponding rails 5.2. The middle part of the slide 5.3 is connected to a transmission belt 501 driven by a servo motor located between the rails on both sides, so it can slide smoothly along the rails under the drive of the servo motor. A lifting cylinder 503 is installed on one side of the slide 5.3 to drive a lifting horizontal bracket 502, and four extended claws 5021 are distributed at intervals on the horizontal bracket 502.

[0024] The specific structure of the feeding device 1 is as follows: Figure 6 As shown, it is composed of a downward-inclined conveying chain 102 driven by a feeding motor 101 installed on a frame, and each link of the downward-inclined conveying chain 102 is spaced apart to place a V-shaped feeding trough 103 for placing the corrugated pipe. A positioning block 104 is installed at one end of the downward-inclined conveying chain 102 for positioning one end of the corrugated pipe to ensure the correct welding position relationship with the welding station.

[0026] When producing the welding joints at both ends of the short corrugated pipe, the feeding device discharges the corrugated pipe with one end against the positioning block. After the first welding station completes the joint welding at one end, the bracket of the position conversion device lifts the corrugated pipe and shifts it to the position where the unwelded end is aligned with the welding gun of the second welding station. The clamping jaws of the clamping and circulation device descend and open, and at the same time grab the corrugated pipes at the output end of the feeding device, the first joint welding station, and the second joint welding station, and then rise. Then, driven by the servo drive mechanism, the unwelded corrugated pipe at the output end of the feeding device is moved to the first joint welding station for welding of one end of the joint, and the corrugated pipe with one end of the joint welded at the first joint welding station and shifted by the position conversion device is moved to the second joint welding station for welding of the joint at the other end. At the same time, the corrugated pipe with both ends welded at the second joint welding station is moved to the cooling device for cooling, thus completing a production cycle. The loading device and the cooling device are driven by their respective motors to transport the workpieces according to the production rhythm time. Therefore, by repeating the above process, the problem of automatic flow of workpieces between various processes in the manufacturing process of the metal hose can be properly solved, providing a reliable guarantee for the efficient, stable and continuous automated production of metal hoses for stoves.

[0027] In addition to the above embodiments, the present invention may also have other implementation modes. Any technical solution formed by equivalent replacement or equivalent transformation falls within the protection scope required by the present invention.
