[0021] Referring to Figures 1 to 5 , the following embodiments are made for the smoke exhaust pipe casing processing equipment of the present invention: A smoke exhaust pipe casing processing equipment, comprising: a first casing device 200, a first material supporting device 300, a second material supporting device 400, a second casing device 500, a pipe pressing driving member 700 and a lifting driving member 800.

[0022] As Figure 1 shown, the first casing device 200, the first material supporting device 300, the second material supporting device 400 and the second casing device 500 are arranged in sequence along the left-right direction. Both the first material supporting device 300 and the second material supporting device 400 have a material supporting part for supporting the round pipe material. Pressing parts are provided on the opposite sides of the first casing device 200 and the second casing device 500. The pipe pressing driving member 700 is used to drive the first casing device 200 to move left and right, and the lifting driving member 800 is used to drive the first material supporting device 300 to move up and down.

[0023] During actual use, the first material supporting device 300 and the second material supporting device 400 can respectively support the inner and outer pipe bodies for casing processing. The pressing part of the second casing device 500 can provide a limit for the end of the outer pipe body. When the pipe pressing driving member 700 drives the first casing device 200 to move rightward, the pressing part of the first casing device 200 can push the inner pipe rightward, so as to realize the casing processing of the inner and outer pipe bodies. After the right end of the inner pipe body is inserted into the left end of the outer pipe body, the lifting driving member 800 can drive the first material supporting device 300 to move downward, so as to avoid the first casing device 200 and provide enough space for the complete casing of the inner and outer pipe bodies. The smoke exhaust pipe casing processing equipment of the present invention can automatically realize the casing processing of the inner and outer pipe bodies of the smoke exhaust pipe, has high production efficiency, and the casing action is reliable, and it is not easy to cause material damage and waste.

[0024] As Figure 1As shown, in this embodiment, the tube pressing part of the first sleeve device 200 is provided with a multi-claw chuck 210 toward the right. The multi-claw chuck 210 is a fixture for clamping a workpiece, which is commonly found in machine tools such as lathes, milling machines, and grinders. It achieves uniform clamping of the workpiece by moving multiple claws (usually 3 claws, 4 claws or 6 claws) toward the center or the outer edge at the same time. Specifically, the first sleeve device 200 of this embodiment is provided with an internally supported self-centering four-claw chuck, which has four claws, all of which move synchronously in the radial direction, and can achieve automatic centering, thereby supporting and clamping the left end of the inner tube body of the smoke exhaust pipe. In some other embodiments, the multi-claw chuck 210 can also adopt an external clamping chuck. The left end of the inner tube body can be clamped by the multi-claw chuck 210. When the first supporting device 300 is moved away from the avoidance position, the left end of the inner tube body is prevented from being suspended in the air, causing the inner tube body and the outer tube body to be axially offset, thereby ensuring that the sleeve action can be carried out stably. To facilitate loading and unloading, the pipe pressing portion of the second sleeve device 500 has a left end surface perpendicular to the left-right direction.

[0025] The inner and outer tubes of the smoke exhaust pipe are welded after rolling, so the tube walls of the inner and outer tubes have welds extending in the axial direction. During the production process, in order to improve the strength of the smoke exhaust pipe, the welds of the inner and outer tubes are staggered 180 degrees from each other.

[0026] In this embodiment, the first supporting device 300 and the second supporting device 400 both include: a supporting wheel group 310 and a material transfer drive unit 320. The supporting wheel group 310 includes two supporting transmission wheels 311, and the axial directions of the two supporting transmission wheels 311 extend left and right. The two supporting transmission wheels 311 are arranged front and back to form a supporting part that can support a round tube. The two supporting transmission wheels 311 are connected to each other in a transmission manner so as to rotate synchronously in the same direction. The material transfer drive unit 320 is used to drive the supporting transmission wheels 311 to rotate. In actual use, a round tube can be placed between the two supporting transmission wheels 311. When the material transfer drive unit 320 drives the supporting transmission wheels 311 to rotate, the round tube thereon can rotate under the action of friction, thereby adjusting the position of the weld bead.

[0027] In a further embodiment, a visual detection mechanism is provided on the front or rear side of the first supporting device 300 and the second supporting device 400, and image recognition is performed through visual detection to control the start and stop of the material transfer drive unit 320, thereby ensuring that the welds of the inner tube body and the outer tube body can be rotated to the front and rear sides respectively.

[0028] See attached Figure 4, in the material supporting wheel set 310 of this embodiment, the material supporting drive wheels 311 are all synchronous belt wheels. The material supporting wheel set 310 further includes a synchronous belt 312 and a belt drive wheel 313. The belt drive wheel 313 and the two material supporting drive wheels 311 are all drivingly connected to the synchronous belt 312, so that the synchronous belt 312 moves along an annular path. The two material supporting drive wheels 311 achieve synchronous drive through the synchronous belt 312, and the synchronous belt 312 is tensioned through the belt drive wheel 313 and forms a depression between the two material supporting drive wheels 311 to support the circular tube. The two belt drive wheels 313 The length specification of the exhaust pipe is generally long. To provide stable supporting for the inner and outer pipe bodies, the left and right ends of the first material supporting device 300 and the second material supporting device 400 of this embodiment are both provided with the material supporting wheel set 310. The two material supporting wheel sets 310 are arranged at intervals left and right. The material transfer driving unit 320 is a micro servo motor, and the material transfer driving unit 320 is arranged between the two material supporting wheel sets 310.

[0029] In some other embodiments, the material transfer driving unit 320 can also adopt other rotary driving elements such as a rotary cylinder, a servo motor, a stepping motor or a pneumatic motor. Synchronous and co-directional drive between the two material supporting drive wheels 311 can be achieved through other drive modes such as chain drive, gear drive or worm and worm gear drive.

[0030] In this embodiment, the exhaust pipe casing processing equipment is provided with a frame 100. The first casing device 200, the first material supporting device 300, the second material supporting device 400 and the second casing device 500 are all arranged on the upper side of the frame 100.

[0031] Specifically, a workbench panel 110 is arranged on the upper side of the frame 100. Two linear guide rails 120 arranged at intervals front and back are arranged on the workbench panel 110, and both of the two linear guide rails 120 extend along the left and right directions.

[0032] The front and rear ends of the first casing device 200 are respectively slidably connected to the frame 100 through the two linear guide rails 120. As Figure 3 shown, the pipe pressing driving member 700 includes: a driving gear 710, a driving rack 720 and a pipe pressing driving motor 730. The driving rack 720 extends along the left and right directions and is fixedly installed on the frame 100. The driving gear 710 is rotatably arranged on the first material supporting device 300 and is drivingly engaged with the driving rack 720. The output shaft of the pipe pressing driving motor 730 is drivingly connected to the driving gear 710. When the pipe pressing driving motor 730 drives the driving gear 710 to rotate, the first casing device 200 can be driven to move left and right through the driving action of the driving gear 710 and the driving rack 720, so as to realize the pipe pressing and reset actions.

[0033] The lifting drive member 800 of this embodiment is arranged on the lower side of the first material supporting device 300. In this embodiment, the lifting drive member 800 is a cylinder arranged in the up-and-down direction. The cylinder body of the lifting drive member 800 is adjustably connected to the frame 100 in the left-and-right direction, and the end of the piston rod of the lifting drive member 800 is fixedly connected to the first material supporting device 300. As Figure 1 and 2 shown, the workbench panel 110 is provided with an avoidance groove 111 extending left and right. In the projection in the up-and-down direction, both the lifting drive member 800 and the first material supporting device 300 are arranged in the avoidance groove 111. In some other embodiments, the lifting drive member 800 can also be a linear drive member such as an electric push rod, a hydraulic push rod, or a screw-nut drive assembly.

[0034] A butting device 600 is further arranged between the first material supporting device 300 and the second material supporting device 400. The butting device 600 includes: a sizing die 610 and a displacement drive member 620. The left and right sides of the sizing die 610 are respectively provided with a necking end 611 and a flaring end 612, and the displacement drive member 620 is used to drive the sizing die 610 to move back and forth.

[0035] During actual use, the inner pipe body and the outer pipe body are clamped by the pipe pressing parts of the first sleeve device 200 and the second sleeve device 500, so that the inner pipe body and the outer pipe body are respectively abutted against the necking end 611 and the flaring end 612 of the sizing die 610, the right end of the inner pipe body is necked, and the left end of the outer pipe body is flared, so that the inner pipe body can be more easily inserted into the outer pipe body. After the sizing process is completed, the displacement drive member 620 drives the sizing die 610 to move forward and avoid, providing space for the sleeving of the inner and outer pipe bodies. During the next sleeve processing, it moves backward to between the first material supporting device 300 and the second material supporting device 400 again.

[0036] Referring to the attached Figure 4 and Figure 5 , in the sizing die 610 of this embodiment, the necking end 611 has a conical concave surface that is wider on the left and narrower on the right, the flaring end 612 has a conical convex surface that is wider on the left and narrower on the right, and the necking end 611 and the flaring end 612 are coaxially arranged.

[0037] In order to facilitate the expansion and contraction process, the expansion and contraction mold 610 is preferably elastically set in the left and right directions. In the present embodiment, the docking device 600 is elastically adjustable in the left and right directions. Specifically, the docking device 600 includes a sliding seat 630. The sliding seat 630 is slidably connected to the frame 100 through the front and rear two linear guide rails 120. The expansion and contraction mold 610 is installed on the upper side of the sliding seat 630 along the front and rear sliding. The shift drive component 620 has a shift drive end that is transmission-connected to the expansion and contraction mold 610 and enables the expansion and contraction mold 610 to move forward and backward relative to the sliding seat 630. The shift drive component 620 can adopt a linear drive component such as a cylinder, an electric push rod, a hydraulic push rod, or a screw nut drive assembly.

[0038] The frame 100 is installed with a limiter by screws, and the limiter is adjustable in the left and right directions by means of a strip-shaped installation groove extending left and right or a plurality of screw holes arranged left and right. The sliding seat 630 is elastically connected to the limiter along the left and right. Before the expansion and closing process is performed, the sliding seat 630 is elastically pressed to the left under the action of elastic force, so that there is enough space between the expansion and closing mold 610 and the second sleeve device 500, so that the outer tube body can be loaded onto the second supporting device 400. During the expansion and closing process, the first sleeve device 200 drives the inner tube body to press to the right, and the right end of the inner tube body presses against the closing end 611. At the same time, the sliding seat 630 can overcome the elastic force and move to the right, and press the outer tube body against the right side of the pressing tube part through the expanding end 612.

[0039] In order to enable the smoke exhaust pipe product that has completed the sleeve processing to be automatically unloaded, a discharge seat 420 is provided between the matching device 600 and the second sleeve device 500 of this embodiment, and the discharge seat 420 is connected to the frame 100. The second supporting device 400 is arranged on the upper side of the discharge seat 420. The discharge seat 420 is provided with a discharge guide groove 421 and a discharge drive unit 422. The discharge guide groove 421 includes a translation section extending forward and backward and a flip section extending downwardly from back to front. The flip section is arranged at the front side of the translation section, and the rear section of the flip section is connected to the front end of the translation section. The second supporting device 400 is provided with a discharge roller 410 that is rollingly embedded in the discharge guide groove 421. The discharge drive unit 422 is used to drive the second supporting device 400 to move relative to the discharge seat 420, so that the discharge roller 410 rolls along the discharge guide groove 421.

[0040] like Figure 5As shown, in this embodiment, both the front and rear sides of the discharge seat 420 are provided with a discharge guide groove 421, and both the left and right sides of the second supporting device 400 are provided with two discharge rollers 410. The two discharge rollers 410 arranged on the same side are arranged front and back and are rollingly embedded in the same discharge guide groove 421. The discharge drive unit 422 adopts a telescopic cylinder, the cylinder body of the discharge drive unit 422 is movably connected to the discharge seat 420, and the piston rod end of the discharge drive unit 422 is transmission-hinged with the second supporting device 400.

[0041] In actual use: the discharging drive unit 422 drives the second supporting device 400 to move forward from the casing station. During this process, both of the discharging rollers 410 move forward in the translation section, and the second supporting device 400 can maintain its posture and translate forward. When the second supporting device 400 moves to the front edge of the frame 100, the discharging roller 410 arranged on the front side moves downward from the translation section to the flip section, thereby driving the second supporting device 400 to flip forward and downward, so that the material on it pours forward to achieve unloading.

[0042] In some other embodiments, the discharge seat 420 has a slideway extending forward and backward, the lower end of the second supporting device 400 is provided with a connecting end connected to the slideway for forward and backward sliding movement, and the flip section extends in an arc around the front end of the slideway. When the discharge drive unit 422 drives the second supporting device 400 to move forward to the front end edge of the frame 100, the connecting end is at the front end of the slideway, and the discharge roller 410 rolls along the flip section, so that the second supporting device 400 flips forward around the connecting end.

[0043] In order to facilitate the production of smoke exhaust pipe sleeves of different lengths, the first supporting device 300, the second supporting device 400 and the second sleeve device 500 are all adjustable in the left and right directions. In this embodiment, the first sleeve device 200 and the second sleeve device 500, as well as the sliding seat 630 and the discharge seat 420 are all connected to the frame 100 by sliding in the left and right directions through the two linear guide rails 120, so that the structure is simple and the sliding installation accuracy between the devices is convenient to control. The first sleeve device 200 is driven by the sleeve driving member to achieve left and right movement. The limiter is adjusted in the left and right directions through the strip installation groove extending left and right or the multiple screw holes arranged left and right, thereby realizing the adjustable setting of the sliding seat 630. The discharge seat 420 and the second sleeve device 500 are both adjusted in the left and right directions through the slider clamp.
