A material moving mechanism for moving the air pipe between the material receiving and processing mechanism and the pipe bending mechanism, and between the pipe bending mechanism and the hole opening mechanism is provided on the machine platform behind the pipe bending mechanism.

It has the advantages of strong followability and precision, and can effectively improve the quality of the bent pipe.

Description

Technical Field

[0001] The invention relates to Europeanized furnace air pipe processing equipment, in particular to Europeanized furnace air pipe automatic production equipment. Background Art

[0002] European-style stoves are designed for outdoor activities such as camping and barbecues, which shows that they are portable and efficient. For example, a European-style stove is specially customized for outdoor camping and barbecue use, with energy-saving and environmentally friendly functions, suitable for outdoor use.

[0003] The video reveals a fully automatic pipe bending machine, whose pipe bending die cooperates with two clamping dies. One of them passively follows the rotation after abutting, and the other one first abuts and then actively moves in the front and back directions. This active movement is currently achieved through a cylinder and a controller.

[0004] Since the rotation of the pipe bending die requires a power device, the second clamping die needs to be driven by a cylinder to actively follow the movement during the rotation. It is difficult to completely synchronize the two systems during control, and lags are prone to occur, resulting in deviations in the clamping position of the second clamping die, and ultimately causing the bending quality to fail to meet the requirements.

DETAILED DESCRIPTION

Those skilled in the art will appreciate that these descriptions are merely illustrative and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0038] Example

[0039] Main plan :

[0040] European furnace gas pipe automation production equipment, such as Figure 1-11 As shown, the machine 01 includes an automatic loading mechanism 10 on the right side of the machine 01. The machine 01 is provided with a material receiving and processing mechanism 20, a pipe bending mechanism 30, and a hole-opening mechanism 40 from left to right. The machine 01 behind the pipe bending mechanism 30 is provided with a material moving mechanism 50 for moving the air pipe 02 between the material receiving and processing mechanism 20 and the pipe bending mechanism 30, and between the pipe bending mechanism 30 and the hole-opening mechanism 40. The pipe bending mechanism 30 includes:

[0041] The rotating assembly 301 is rotatably mounted above the machine 01 and has an output gear 3011;

[0042] The bending assembly includes a bending die 302 provided on the rotating assembly 301 and rotating with the rotating assembly 301 and having a bending groove, a rotating base provided on the rotating assembly 301 and rotating with the rotating assembly 301, a first clamping die 303 provided on the rotating base and having a first clamping groove, a mounting frame provided on the machine 01, and a second clamping die 304 provided on the mounting frame and having a second clamping groove. The machine 01 is provided with a first sliding mechanism that moves left and right, and the first clamping die 303 is provided on the first sliding mechanism. The first sliding mechanism drives the first clamping die 303 to slide and abut against the bending film so that the first clamping groove and the bending groove enclose a circular first clamping hole. The machine 01 is also provided with a second sliding mechanism that moves left and right, and a third sliding mechanism that moves forward and backward is provided on the sliding part of the second sliding mechanism, and the second clamping die 304 is provided on the sliding part of the third sliding mechanism.

[0043] The power assembly 311 includes a drive motor mounted on the machine 01 and a reducer connected to the output end of the drive motor. The reducer has an input gear that is in transmission connection with the rotating assembly 301. The transmission connection can be achieved by a combination of a timing belt 503 and gears or by multiple meshing gears.

[0044] An air source assembly is provided below the machine platform 01 and is used to drive the first sliding mechanism and the second sliding mechanism to slide;

[0045] Among them, the sliding part of the third sliding mechanism is driven by the driving part, which includes a first piston cylinder 305. The piston rod of the first piston cylinder 305 is connected to the sliding part of the third sliding mechanism. A linkage driving component is provided between the rotating component 301 and the first piston cylinder 305. The linkage driving component includes a driving gear shaft 307 meshing with the output gear 3011, a ball screw and a second piston cylinder 310. A group of meshing bevel gears are provided on the driving gear shaft 307 and the screw 308 of the ball screw. The nut seat 309 of the ball screw is connected to the piston rod of the second piston cylinder 310. The second piston cylinder 310 is connected to the cavity inside the first piston cylinder 305 through the pipe 306, so that the piston rod of the second piston cylinder 310 slides inward and presses the fluid inside the second piston cylinder 310 into the first piston cylinder 305, driving the piston rod of the first piston cylinder 305 to slide outward, and finally pushing the slider to slide, thereby driving the second clamp 304 to move forward and backward. The first and second sliding mechanisms are driven by air supplied by the air source assembly, while the third sliding mechanism is driven by the aforementioned driving portion. Furthermore, the first, second, and third sliding mechanisms can all be configured as sliding structures consisting of slide rails, slide rails, and cylinders, in which case the aforementioned sliding portion is a slider. This solution utilizes a ball screw mechanism to redirect the horizontal rotation of the rotating assembly 301, which then drives the sliding of the nut seat 309, thereby driving the piston rods of the two piston cylinders to move, ultimately driving the second clamp 304 to move forward and backward. This movement is passive, and the distance of movement is entirely determined by the angle of rotation of the rotating assembly 301, offering the advantages of high tracking and precision. The screw 308 is rotatably mounted at the bottom of the machine platform 01 to maintain its original position. Specifically, both ends of the screw 308 are extended and provided with unthreaded sections, and two screw 308 seats are provided at the unthreaded sections to support it and allow it to rotate in place. This portion is not shown in the figure.

When the material transfer gap 2011 is opposite to the material storage gap 2041, the material transfer rack 201 lifts up the air pipe 02 in the material storage gap 2041 when it rises, and moves left and right to the material storage gap 2041 at the processing station and then descends. The air pipe 02 is transferred to the material storage gap 2041. At this time, the air pipe 02 is clamped by the clamp 90 and then tapped or flattened.

The portion of the screw rod 504 that extends into the mounting cavity is equipped with a gear that meshes with the timing belt 503. The motor drives the two gears on the motor shaft to rotate, which, through the timing belt 503, drives the two screw rods 504 to rotate. This in turn drives the two nut plates 505 to slide on the screw rods 504, ultimately driving the claw body 506 to rotate about its hinge point to open and close the claw body 506. The two left-side clamping jaws 502 are arranged in a left-right direction, while the two right-side clamping jaws 502 are arranged in a front-back direction.

The material moving mechanism 50 clamps the air pipe 02 and places it in the placement hole 402, and then the pressure plate 405 and the push plate 406 slide horizontally to press the air pipe 02 into the groove of the limit block, and then the drilling machine 401 descends and extends the drill bit into the through hole and descends to drill a hole in the air pipe 02.
