[0002] Metal hoses are important components in the connecting pipelines of modern industrial equipment. Generally, metal hoses are composed of three major parts: corrugated pipes, wire meshes, and joints. The corrugated pipe is the main body of the metal hose, playing a flexible role. The wire mesh plays a role in strengthening and shielding. The joint plays a connecting role. Metal hose products include oil suction and delivery hoses, steam hoses, sandblasting hoses, acid and alkali suction and delivery hoses, food hoses, oxygen blowing hoses, and various special-shaped hoses, etc. They are widely used in industries such as machinery, chemical engineering, petroleum, metallurgy, and food.

[0003] The existing metal hoses have limited pressure resistance and heat insulation performance. By adding a pressure-resistant and heat-insulating layer outside the metal corrugated pipe to improve the pressure resistance and heat insulation performance of the metal hose, however, during the manufacturing process, due to the natural tension of the corrugated sections of the metal corrugated pipe, the tension degree of each corrugated pipe is inconsistent, resulting in inconsistent forming shapes of the pressure-resistant and heat-insulating layers manufactured later, making the quality of the metal hose unstable and difficult to ensure the quality of the metal hose.

[0040] The correction unit 84 includes a push rod 11 slidably sleeved with the push plate 83, one end of the push rod 11 extending from the push plate 83 is fixedly connected to the extension plate 81, and the other end of the push rod 11 is fixedly connected to a guide plate 12, and a slide groove 13 distributed in an array is provided on the side of the guide plate 12 close to the push rod 11, and the slide groove 13 is slidably connected to a correction rod 14 moving along the diameter direction of the guide plate 12, and the correction rod 14 is hinged with a pull rod 15 hinged to the push plate 83, and the end of the correction rod 14 extending from the slide groove 13 is an arc-shaped structure;

[0041] When the metal bellows is corrected and transported, the drive unit 5 on the reciprocating mechanism 6 is started to push the carrier plate toward one side of the positioning mechanism 4, and the clamping mechanism 7 and the correction mechanism 8 move toward one side of the positioning mechanism 4. Thereafter, the drive unit 1 73 on the top of the support plate 71 is started to push the cross plate 74 downward, and then the movable plate 75 also moves downward. At this time, the two sets of correction mechanisms 8 also move downward, so that the correction mechanism 8 moves downward to the end of the positioned metal bellows, and then the drive unit 2 is started to move the two sets of movable plates 75 toward one side close to each other, so that the two The correction mechanism 8 of the group moves toward one side close to each other, and the correction unit 84 on the correction mechanism 8 extends into the metal bellows from the opening at the end of the metal bellows. According to the actual correction needs, the correction unit 84 is adjusted to extend into the metal bellows by using the driving unit 2. The correction rod 14 on the correction unit 84 extends into the outermost corrugation of the metal bellows as the best correction state. At the same time, the outer diameter of the end of the correction rod 14 is consistent with the inner diameter of the outermost corrugation of the metal bellows, so that the end of the correction rod 14 can be completely attached to the inner wall of the outermost corrugation of the metal bellows;

[0042] When the driving unit 3 82 is started, the push plate 83 is pushed to move, and then the pull rod 15 drives the correction rod 14 to move, and the correction rod 14 moves toward the inner wall direction of the outermost corrugation of the metal bellows, and the correction rod 14 can resist and squeeze the outermost corrugation of the metal bellows, thereby adjusting the length of the metal bellows between the two sets of push plates 83, and fine-tuning the tension state of the metal bellows, so that the clamping length and tension state of the clamped metal bellows are consistent, and then the reciprocating mechanism 6, the clamping mechanism 7 and the correction mechanism 8 are used to transport the metal bellows in the corrected clamping state to the injection mold of the injection molding machine for injection molding, wherein the injection molding machine adopts a vertical injection molding machine;

[0043] like Figure 8 As shown, the injection mold includes a molding upper mold and a molding lower mold, and the molding upper mold and the molding lower mold each include a mold 31, a molding cavity 34 disposed on the mold 31, positioning cavities 33 opened at both ends of the molding cavity 34, and an extension cavity 32 opened at one end of the positioning cavity 33 away from the molding cavity 34 and penetrating the mold 31;

[0045] Keep the states of multiple metal bellows conveyed into the injection molding machine for injection molding consistent to ensure the post-injection...

[0046] The rotating mechanism 2 includes a substrate fixed inside the box body 1, a rotating rod rotatably connected to the top of the substrate and rotatably connected to the box body 1. One end of the rotating rod extending out of the top of the box body 1 is fixedly connected to a tray fixedly connected to the bottom of the support plate 5. The bottom of the rotating rod is fixedly connected to a rotating shaft rotatably connected to the substrate. One end of the rotating shaft extending out of the bottom of the substrate is equipped with a motor. When the motor starts, it drives the rotating shaft and the rotating rod to rotate, thereby driving the support plate 5 to rotate, making the entire conveying component 3 rotate, adjusting the orientation of the conveying component 3, and realizing the adjustment of the material taking and feeding positions.

[0047] The positioning mechanism 4 includes a fixing plate 41 fixedly connected to the top of the box body 1 and a material placing plate 42 fixedly connected to the top of the fixing plate 41.

At the other open end of the material placing groove 43, a side plate 45 fixed to the fixing plate 41 is provided. The side plate 45 is fixedly connected with a driving unit four 46. The output end of the driving unit four 46 is fixedly connected with a pressing plate 47 located between the side plate 45 and the material placing plate 42. The top of the pressing plate 47 is fixedly connected with a contact plate 48 with an arc-shaped structure. When initially positioning the metal bellows, the metal bellows are sequentially placed in the material placing groove 43, and then the driving unit four 46 is started to push the pressing plate 47 to move. The contact plate 48 on the pressing plate 47 pushes the metal bellows to move from the end of the metal bellows. One end of the metal bellows abuts against the contact plate 48, and the other end abuts against the baffle plate 44, realizing the positioning operation of the metal bellows. At the same time, the pressing plate 47 pushes the pressing mechanism 9 to move, causing the pressing mechanism 9 to deflect and restrict and protect from the top of the metal bellows, preventing the metal bellows from popping out from the material placing groove 43 during the extrusion positioning process.

[0048] The reciprocating mechanism 6 includes two groups of bearing plates arranged on the top of the support plate 5, and the bearing plates are fixedly connected to the bottom of the adjacent support plates 71.

[0050] The pressing mechanism 9 includes a storage groove 91 opened at the top of the positioning mechanism 4 and an installation groove 92 opened inside the positioning mechanism 4. The storage groove 91 is located on one side of the top opening of the material discharging groove 43. The installation groove 92 is arranged inside the material discharging plate 42. The storage groove 91 is provided with a turning plate 93. One end of the bottom of the turning plate 93 is fixedly connected with a driven rod 94 rotatably connected to the material discharging plate 42 of the positioning mechanism 4. The bottom of the driven rod 94 is threadedly sleeved with a sleeve 95 slidably connected to the material discharging plate 42 of the positioning mechanism 4. The bottom of the storage groove 91 is provided with a first installation hole located on the material discharging plate 42, and the first installation hole is rotatably sleeved with the driven rod 94. The bottom of the first installation hole is provided with a second installation hole communicated with the installation groove 92, and the second installation hole is slidably sleeved with the sleeve 95;

[0051] One end of the sleeve 95 extending into the installation groove 92 is fixedly connected with a pressing rod.

An inclined pressing groove 97 is opened on one side of the pushing rod 96. The higher end of the pressing groove 97 is provided with a holding groove 98 arranged along the length direction of the pushing rod 96, and the holding groove 98 and the pressing groove 97 are slidably connected with the pressing rod. One end of the pushing rod 96 extending into the installation groove 92 is fixedly connected with a spring fixedly connected to the inner side wall of the end of the installation groove 92;

[0052] When the pressing plate 47 moves, the pressing plate 47 drives the pushing rod 96 to move towards the installation groove 92. The pressing groove 97 on the pushing rod 96 presses the pressing rod on the sleeve 95, causing the pressing rod to move upward, driving the sleeve 95 to move upward, and then causing the driven rod 94 to rotate under the action of the thread, so that the turning plate 93 rotates, deflecting the turning plate 93 located in the storage groove 91 towards the side of the metal bellows placed on the top of the material discharging groove 43, so that the turned turning plate 93 can block the metal bellows, avoiding the situation that the metal bellows pops out of the material discharging groove 43 due to clamping when the positioning mechanism 4 positions the metal bellows.

[0053] The number of the pressing mechanisms 9 is the same as the number of the calibration units 84 where the push plate 83 is located. The distance between adjacent pressing mechanisms 9 is the same as the distance between adjacent calibration units 84. Casters are installed at the bottom of the box body 1.
