[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The forming device for the double-layer composite metal bent pipe includes a protection component as one of its parts. When processing the double-layer composite metal bent pipe, through the forming mechanism, the forming work is carried out on it. When the forming work is carried out, it is necessary to protect it to prevent debris from flying out and affecting the safety of the operator. Start the telescopic rod, which drives the fixed block and the protection frame to move upward. The gear rotatably connected to the outer wall of the protection frame moves accordingly. Since the gear meshes with the fixed rack, under the restriction of the fixed rack, the gear starts to rotate. Since the gear meshes with the moving rack, when the moving rack moves, the moving rack drives the cover plate to move towards each other. Since the slider fixedly installed on the top of the protection frame and the chute opened at the bottom of the cover plate are slidably arranged, under its restriction, the cover plate can slide more stably. When the protection frame rises, in cooperation with the cover plate moving towards each other, the forming mechanism is protected to prevent debris from flying out and hurting people. This structure can make the processing of the double-layer composite metal bent pipe safer.

[0015] 2. The forming device for the double-layer composite metal bent pipe includes an ash suction component as one of its parts. When the double-layer composite metal bent pipe is undergoing forming work, some processing debris will be generated. When the protection frame moves upward, the protection frame drives the sliding rod to move upward accordingly. The sealing ring fixedly installed at the end of the sliding rod slides on the inner wall of the air pipe. The sealing ring pumps the gas inside the air pipe, and the air pipe pumps the gas at the collecting hopper to suck in the processing debris and inhale the debris into the one-way collecting bottle for collection through the one-way collecting bottle.

Detailed implementation manners

[0023] For a clearer understanding of the technical features, objectives, and effects of the present utility model, the specific implementation manners of the present utility model will now be described with reference to the accompanying drawings.

[0024] Embodiment 1

[0025] A preferred embodiment of a forming device for a double-layer composite metal bent pipe provided by the present utility model is as Figures 1 to 6 shown: A forming device for a double-layer composite metal bent pipe includes a processing table 1;

[0026] A forming mechanism 2 is arranged on the top surface of the processing table 1;

[0027] And a processing component 3 arranged outside the forming mechanism 2. The processing component 3 includes a protective component 31 arranged outside the forming mechanism 2. The protective component 31 includes a telescopic rod 311 fixedly installed inside the processing table 1. A fixed block 312 is fixedly installed at the end of the telescopic rod 311. A protective frame 313 is fixedly installed on the outer wall of the fixed block 312. A gear 314 is rotatably connected to the outer wall of the protective frame 313. The gear 314 meshes with a moving rack 315. A cover plate 316 is fixedly installed on the outer wall of the moving rack 315. A chute 317 is opened at the bottom of the cover plate 316. A slider 318 is slidably arranged inside the chute 317. A fixed rack 319 is fixedly installed on the top surface of the processing table 1.

[0028] In this embodiment, when processing the double-layer composite metal bent pipe, the forming mechanism 2 is used to perform the forming work. When the forming work is carried out, it is necessary to protect it to prevent debris from flying out and affecting the safety of the operator. The telescopic rod 311 is started, which drives the fixed block 312 and the protective frame 313 to move upward. The gear 314 rotatably connected to the outer wall of the protective frame 313 moves accordingly. Since the gear 314 meshes with the fixed rack 319, under the restriction of the fixed rack 319, the gear 314 starts to rotate. Since the gear 314 meshes with the moving rack 315, when the moving rack 315 moves, the moving rack 315 drives the cover plate 316 to move towards each other. Since the slider 318 fixedly installed at the top of the protective frame 313 is slidably arranged in the chute 317 opened at the bottom of the cover plate 316, under its restriction, the cover plate 316 can slide more stably. When the protective frame 313 rises, in cooperation with the cover plate 316 moving towards each other, the forming mechanism 2 is protected to prevent debris from flying out and hurting people. This structure can make the processing of the double-layer composite metal bent pipe safer.

[0029] Further, the fixed rack 319 and the moving rack 315 are arranged in a staggered manner. The moving rack 315 and the fixed rack 319 mesh with the gear 314. Under its restriction, the rotating gear 314 can drive the moving rack 315 to move.

[0030] Furthermore, the protective frame 313 is slidably arranged inside the processing table 1. The slider 318 fixedly installed at the top of the protective frame 313 is slidably arranged in the chute 317 opened at the bottom of the cover plate 316. Under the restriction of the slider 318, the cover plate 316 can slide stably.

[0031] Embodiment 2

[0032] On the basis of Embodiment 1, a preferred embodiment of a forming device for a double-layer composite metal bent pipe provided by the present utility model is as Figures 1 to 6 shown: The dust suction assembly 32 includes a slide bar 321 fixedly installed inside the protective frame 313. A sealing ring 322 is fixedly installed at the end of the slide bar 321. An air pipe 323 is slidably arranged on the outer wall of the sealing ring 322. A one-way collection bottle 324 is communicated with the outer wall of the air pipe 323. A collection hopper 325 is communicated with the end of the air pipe 323. A support plate 326 is fixedly installed on the outer wall of the air pipe 323.

[0033] In this embodiment, when the double-layer composite metal bent pipe is performing the forming work, some processing debris will be generated. When the protective frame 313 moves upward, the protective frame 313 drives the slide bar 321 to move upward accordingly. The sealing ring 322 fixedly installed at the end of the slide bar 321 slides on the inner wall of the air pipe 323. The sealing ring 322 pumps the gas inside the air pipe 323. The air pipe 323 pumps the gas at the collection hopper 325 to suck in the processing debris and suck the debris into the one-way collection bottle 324 for collection through the one-way collection bottle 324.

[0034] Further, the sealing ring 322 is made of rubber. The outer wall of the sealing ring 322 slides in a sealed manner with the inner wall of the air pipe 323. Under the limitation of the sealed sliding of the sealing ring 322, the gas inside the air pipe 323 can be pushed to perform the dust suction work.

[0035] In addition, the one-way collection bottle 324 is a one-way valve. The one-way collection bottle 324 is threadedly sleeved on the outer wall of the air pipe 323. Under its limitation, when the sliding rod 321 drives the sealing ring 322 to slide downward, the sealing ring 322 will not bring out the dust inside the air pipe 323 again, so as to ensure the debris collection effect.

[0036] The above is only a schematic specific embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present invention shall fall within the scope of protection of the present invention. Moreover, it should be noted that the components of the present invention are not limited to the above overall application. Each technical feature described in the specification of the present invention can be used alone according to actual needs or combined in multiple ways. Therefore, the present invention should reasonably cover other combinations and specific applications related to the inventive points of this case.
