The second tooling 3 and the third tooling 4 are installed on the waste stacking mechanism 5. The second tooling 3 is used to clamp and fix the first waste 200 formed after cutting, and the third tooling 4 is used to clamp and fix the second waste 300 formed after cutting; the waste stacking mechanism 5 is used to drive the second tooling 3 and the third tooling 4 to coaxially rotate together or rotate away, and when rotating together, the first waste 200 and the second waste 300 are distributed up and down above the cutting platform 1; the lifting device 7 is used to drive the first waste 200 and the second waste 300 to move downward through the channel 8 on the cutting platform 1, and stack the first waste 200 and the second waste 300 below the cutting platform 1.

[0035] It should be noted that before applying the above technical solution, a pit is constructed on the ground below the channel 8 in advance, so that a carrier for carrying the first waste 200 and the second waste 300 can move between the ground and the bottom of the pit through the pit, thereby facilitating the collection and transportation of the first waste 200 and the second waste 300.

[0036] When applying the above technical solution, one end of the tubular metal blank is clamped and fixed on the first tooling 2, the second tooling 3 and the third tooling 4 are both clamped on the tubular metal blank, and the second tooling 3 and the third tooling 4 are both gap-matched with the tubular metal blank, so that the first tooling 2 can drive the tubular metal blank to rotate.

[0037] When cutting a tubular metal blank, firstly, the first tool 2 is rotated and the cutting head of the three-axis laser cutting machine 14 is moved to cut two first axial cutting grooves parallel to the axial direction on the tubular metal blank, and the first axial cutting groove passes through one end of the tubular metal blank facing the lifting device 7, and the first axial cutting groove does not pass through the end of the tubular metal blank facing the first tool 2; then, along the circumferential direction, a circumferential cutting groove is cut with one end of the first axial cutting groove facing the first tool 2 as the starting position, and similarly, another circumferential cutting groove is cut, and the two circumferential cutting grooves are not connected; then, a second axial cutting groove is cut between the two first axial cutting grooves, and the second axial cutting groove passes through one end of the tubular metal blank facing the lifting device 7, so that the sides of the two circumferential cutting grooves close to each other both point to the second axial cutting groove; finally, the two circumferential cutting grooves are connected. According to the above description, the cutting path changes as follows: Fig.11 shown.

[0038] It should be noted that after the cutting of the circumferential cutting groove is completed and before the cutting of the second axial cutting groove is performed, the second tool 3 and the third tool 4 are used to clamp and fix the tubular metal blank; after the cutting of the second axial cutting groove is completed, the second tool 3 is located between the second axial cutting groove and a first axial cutting groove, and is close to the first axial cutting groove; the third tool 4 is located between the second axial cutting groove and another first axial cutting groove, and is close to the first axial cutting groove; the relative positions of the second tool 3, the third tool 4, the first transverse cutting groove and the second transverse cutting groove are as shown in FIG. Fig.12 shown.

[0039] After the two circumferential cutting grooves are connected, the first waste material 200 and the second waste material 300 are clamped and fixed by the second tooling 3 and the third tooling 4 respectively, and the formed cylinder 100 is clamped and fixed by the first tooling 2 .

[0040] It should be noted that the circumferential cutting groove and the first axial cutting groove may form a right angle or an arc transition, such as Fig.13 The cylinder 100 shown is an arc transition.

[0041] As a further explanation of the above technical solution, Figure 2 , Figure 3 and Figure 4As shown, the waste stacking mechanism 5 includes a T-shaped seat 51, which is arranged on the extension line of the central axis of the tubular metal blank, the end of the T-shaped seat 51 with a small diameter is the small end and faces the tubular metal blank, and the end of the T-shaped seat 51 with a large diameter is the large end. The connecting device 6 includes a stud 61 and a connecting nut 62 that match each other. The hoisting device 7 includes a first lifter 71, a second lifter 72, a connecting beam 73 and a hanging beam 74, the shell of the first lifter 71 is fixed on the top surface of the mounting frame 13, the output shaft of the first lifter 71 passes through the mounting frame 13 downward, and is fixedly connected to the connecting beam 73, the shell of the second lifter 72 is fixed on the top surface of the connecting beam 73, and the shell of the second lifter 72 passes through the mounting frame 13 upward, the output shaft of the second lifter 72 passes through the connecting beam 73 downward, and is fixedly connected to the hanging beam 74. It should be noted that the first lifter 71 and the second lifter 72 can be selected as any one of a hydraulic cylinder, an electric push rod, and a cylinder.

[0042] When the waste stacking mechanism 5 and the lifting device 7 are connected by the connecting device 6, one end of the stud 61 is first welded and fixed to the large end surface of the T-shaped seat 51, and then the stud 61 is passed through the hanging beam 74, and the connecting nut 62 is screwed on the stud 61, and the connecting nut 62 is tightened to make the T-shaped seat 51 and the hanging beam 74 close.

[0043] Furthermore, the waste stacking mechanism 5 also includes a first swing arm 52, a second swing arm 53, an extension arm 54 and a displacement driving device 55; the first swing arm 52 and the second swing arm 53 are rotatably sleeved on the outer surface of the small end of the T-shaped seat 51 and are distributed in a V shape; the extension arm 54 is slidably installed at the distal end of the first swing arm 52, one end of the extension arm 54 is installed with the second tooling 3, and the distal end of the second swing arm 53 is installed with the third tooling 4; the displacement driving device 55 is fixedly installed on the T-shaped seat 51, and the displacement driving device 55 has two output ends, which are respectively connected to the first swing arm 52 and the second swing arm 53; the displacement driving device 55 drives the distal end of the first swing arm 52 and the distal end of the second swing arm 53 to swing closer or swing away, thereby realizing the swinging closer or swinging away of the second tooling 3 and the third tooling 4. It should be noted that the distal end of the first swing arm 52 is an end of the first swing arm 52 that is radially away from the swing center of the swing trajectory, and the distal end of the second swing arm 53 is an end of the second swing arm 53 that is radially away from the swing center of the swing trajectory.

[0044] The first swing arm 52 is provided with a first driving device 56 for driving the extension arm 54 to slide on the first swing arm 52. The moving direction of the output end of the first driving device 56 is set at an angle with the horizontal plane, so that when the extension arm 54 is pushed out by the first driving device 56 and the first waste material 200 is moved outward, the moving track of the extension arm 54 is at an angle with the horizontal plane, so that the moving track of the first waste material 200 is at an angle with the horizontal plane, providing a height for the subsequent swinging of the first waste material 200 to the top of the second waste material 300. It should be noted that the first driving device 56 in this embodiment is any one of a hydraulic cylinder, an electric push rod or a pneumatic cylinder, so the hydraulic cylinder housing, the electric push rod housing or the cylinder housing is fixed on the first swing arm 52, and the hydraulic cylinder piston rod, the electric push rod piston rod or the cylinder piston rod passes through the first swing arm 52 and is connected and fixed to the extension arm 54.

[0045] It should be noted that, in this embodiment, specific examples of the second tooling 3, the third tooling 4 and the displacement driving device 55 are also provided, and the second tooling 3 and the third tooling 4 have the same structure. The details are as follows.

[0046] like Figure 4 and Figure 5 As shown, the second tooling 3 includes a fixing base 31 for connecting and fixing with the extension arm 54 and two support plates 311 fixed on both sides of the fixing base 31, and a blocking rod 32, an outer clamping plate 33 and an inner clamping plate 34 are arranged between the two support plates 311. The outer clamping plate 33 and the inner clamping plate 34 are respectively used to match the outer curved surface and the inner curved surface of the first waste material 200. The first waste material 200 can be clamped and fixed by bringing the outer clamping plate 33 and the inner clamping plate 34 closer to each other.

[0047] The baffle rod 32 connects and fixes the two support plates 311, and the outer clamp plate 33 is connected to the two support plates 311 by rotating the axis, and a first elastic member 331 is arranged between the outer clamp plate 33 and at least one support plate 311. Through the structure arranged in this way, the baffle rod 32 is used to prevent the outer clamp plate 33 from moving to the side away from the outer curved surface of the first waste material 200, and the first elastic member 331 allows the outer clamp plate 33 to automatically rebound and contact the baffle rod 32 after swinging to the side of the inner clamp plate 34. It should be noted that the first elastic member 331 can be any one of a spring, a coil spring or a torsion spring, and the spring, the coil spring or the torsion spring is sleeved on the axis, and the two ends of the spring, the two ends of the coil spring or the two ends of the torsion spring are respectively connected and fixed to the outer clamp plate 33 and the support plate 311.

[0048] The inner clamping plate 34 is rotatably installed between the two support plates 311 through the gear shaft 35. The gear shaft 35 is rotated by the pusher 36 and the driving rack 361. The pusher 36 is installed on the fixed seat 31. The driving rack 361 is connected to the output end of the fixed pusher 36, and the driving rack 361 is meshed with the gear shaft 35. The pusher 36 drives the driving rack 361 to move, so that the gear shaft 35 rotates, and the inner clamping plate 34 swings relative to the outer clamping plate 33. The metal tubular blank can rotate between the outer clamping plate 33 and the inner clamping plate 34. By rotating the inner clamping plate 34 to the extreme position on the side of the outer clamping plate 33, the inner clamping plate 34 and the outer clamping plate 33 can cooperate to clamp and fix the metal tubular blank. By swinging the inner clamping plate 34 to the extreme position on the side away from the inner clamping plate 34, the first waste material 200 can be separated from the second tooling 3.

[0049] The pusher 36 can be any one of an electric push rod, a hydraulic cylinder or a pneumatic cylinder, and the electric push rod housing, the hydraulic cylinder housing or the cylinder housing is fixed on the fixing seat 31, and the hydraulic cylinder piston rod, the electric push rod piston rod or the cylinder piston rod passes through the fixing seat 31 and is connected and fixed to the driving rack 361.

[0050] It should be noted that, since the second fixture 3 and the third fixture 4 are consistent in structure and function, the structural composition, operation mode and connection mode of the third fixture 4 with the second swing arm 53 will not be described in detail.

[0051] like Figure 4 As shown, the displacement driving device 55 includes a connecting plate 551, a dual-output shaft motor 552, two screw rods 553 with opposite thread rotation directions, two telescopic rods 554, two displacement slots 555 and two displacement columns 556, wherein the dual-output shaft motor 552 is connected and fixed to the T-shaped seat 51 through the connecting plate 551, and a screw rod 553 is fixed to each of the two output ends of the dual-output shaft motor 552, and the fixed ends of the two telescopic rods 554 are respectively sleeved on the outer surfaces of the two screw rods 553 and are connected to the screw rods 553. The two telescopic rods 554 are threadedly matched, and the moving ends are respectively connected to a displacement column 556, which penetrates and rotates to connect the telescopic rods 554; the two screw rods 553 are driven to rotate by the dual output shaft motor 552, so that the two telescopic rods 554 can be moved closer to each other or farther away from each other; the two displacement columns 556 respectively pass through the two displacement grooves 555 on the connecting plate 551, and the two displacement columns 556 are respectively connected and fixed to the first swing arm 52 and the second swing arm 53; the two displacement grooves 555 are both set in an arc shape. By bringing the two telescopic rods 554 closer to each other, the two displacement columns 556 are respectively moved along the two arc-shaped displacement grooves 555, thereby driving the first swing arm 52 and the second swing arm 53 to swing on the T-shaped seat 51, and bringing the distal ends of the first swing arm 52 and the second swing arm 53 closer to each other, and by moving the two telescopic rods 554 away from each other, the distal ends of the first swing arm 52 and the second swing arm 53 can be moved away from each other.

[0052] After the second fixture 3 and the third fixture 4 clamp and fix the first waste material 200 and the second waste material 300 respectively, the first driving device 56 pushes out the second fixture 3, so that the first waste material 200 moves outward a specified distance relative to the second waste material 300, and then the dual-output shaft motor 552 drives the two screw rods 553 to rotate, so that the two telescopic rods 554 move closer to each other, drive the first swing arm 52 and the second swing arm 53 to swing, drive the second fixture 3 and the third fixture 4 to swing closer, so that the first waste material 200 and the second waste material 300 move in an up and down distribution state. At this time, the fan angles of the first waste material 200 and the fan angles of the second waste material 300 both point vertically downward, as shown in FIG. Fig.13 shown.

[0053] Then, the first waste material 200 and the second waste material 300 are driven downward by the lifting device 7, and the cylinder 100 is rotated by the first tooling 2, so that the notch cut on the cylinder 100 corresponds to the channel 8, and the first waste material 200 and the second waste material 300 pass through the notch and the channel 8 in turn and move to the bottom of the cutting platform 1. Then, the second tooling 3 and the third tooling 4 release the first waste material 200 and the second waste material 300 respectively, so that the first waste material 200 and the second waste material 300 are stacked on the carrier.

[0054] Finally, the cylinder 100 is removed from the first tool 2. The second tool 3 and the third tool 4 are moved up to the highest position by the hoisting device 7.

Through the first support frame 9 and the second support frame 10, the stability of the first waste 200 and the second waste 300 in the cutting and forming process is enhanced to ensure the cutting effect; through the first support frame 9 and the second support frame 10, the stability of the first waste 200 and the second waste 300 in the swinging and approaching process is enhanced.

[0056] The moving mechanism 11 includes a support seat 111, a moving beam 112 and a moving drive device 113. The support seat 111 is fixedly sleeved on the outer surface of the small end of the T-shaped seat 51, the moving beam 112 penetrates and slidably connects the support seat 111, and the moving drive device 113 is installed between the support seat 111 and the moving beam 112.

By driving the moving beam 112 with the moving drive device 113, the first support frame 9 and the second support frame 10 can be horizontally moved to the bottom of the first waste 200 and the bottom of the second waste 300, respectively, or the first support frame 9 and the second support frame 10 can be horizontally moved out from the bottom of the first waste 200 and the bottom of the second waste 300, respectively.

The driving motor 1131 drives the driving gear 1132 to rotate, thereby realizing the horizontal movement of the moving beam 112 on the support seat 111.

[0058] The first support frame 9 and the second support frame 10 are both C-shaped frames, the first support frame 9 is slidably mounted on two X-shaped brackets 114, and the second support frame 10 is fixed on the two X-shaped brackets 114. A second driving device 115 for driving the first support frame 9 to slide is provided on at least one X-shaped bracket 114, and the moving track of the first support frame 9 is parallel to the moving track of the extension arm 54; the second driving device 115 can be any one of an electric push rod, a hydraulic cylinder or a pneumatic cylinder, and the electric push rod housing, the hydraulic cylinder housing or the cylinder housing is fixed on the X-shaped bracket 114, and the hydraulic cylinder piston rod, the electric push rod piston rod or the pneumatic cylinder piston rod is connected and fixed to the first support frame 9; when the extension arm 54 slides to push out the second tooling 3 and the first waste material 200, the second driving device 115 pushes out the first support frame 9 synchronously, so that the first waste material 200 is pushed out smoothly.

[0059] It also includes a stabilizing mechanism 12, which includes a V-shaped bracket 121, a first pressing plate 122 and a second pressing plate 123. The V-shaped bracket 121 is fixed on the T-shaped seat 51 at one end surface of the tubular metal blank, and the movable beam 112 is located on the inner side of the V-shaped bracket 121. The first pressing plate 122 and the second pressing plate 123 are rotatably installed on the two inner side surfaces of the V-shaped bracket 121 through axes. The first pressing plate 122 and the second pressing plate 123 are respectively used to press the outer curved surface of the first waste 200 and the outer curved surface of the second waste 300 to further enhance the stability of the first waste 200 and the second waste 300 during the cutting and forming process.

[0060] The second elastic member 124 is disposed between the first pressing plate 122 and the V-shaped bracket 121, and between the second pressing plate 123 and the V-shaped bracket 121, so as to press the first pressing plate 122 and the second pressing plate 123 onto the first waste material 200 and the second waste material 300, respectively. In the process of the second driving device 115 pushing out the first support frame 9, the first pressing plate 122 swings outward synchronously, driving the second elastic member 124 on the first pressing plate 122 to deform elastically. The second elastic member 124 can be any one of a spring, a coil spring or a torsion spring, which is sleeved on the shaft, and the two ends of the spring, the two ends of the coil spring or the two ends of the torsion spring are respectively connected and fixed to the first pressing plate 122 and the V-shaped bracket 121 or are respectively connected and fixed to the second pressing plate 123 and the V-shaped bracket 121.

[0061] In this embodiment, the moving beam 112 , the first support frame 9 and the second support frame 10 all move inside the V-shaped support 121 .

[0062] In this embodiment, after the first waste material 200 and the second waste material 300 are moved to the bottom of the cutting platform 1, the mobile driving device 113 drives the moving beam 112 to move, so that the first support frame 9 and the second support frame 10 are moved horizontally out from under the first waste material 200 and the bottom of the second waste material 300 respectively, and then, the second tooling 3 and the third tooling 4 release the first waste material 200 and the second waste material 300 respectively, and the lifting device 7 is used to drive the second tooling 3, the third tooling 4, the first pressure plate 122 and the second pressure plate 123 to move up and separate from the first waste material 200 and the second waste material 300.

[0063] Embodiment 3, as Figure 8 , Fig. 9 and Fig.10 As shown, a cutting and forming device for a tin melting furnace is different from Example 2 in that:

[0064] A guide slot 58 is disposed on each of the first swing arm 52 and the second swing arm 53; two displacement posts 556 extend into the two guide slots 58 respectively;

[0065] The extension arm 54 is provided with a linear tooth portion 541, and the linear tooth portion 541 is arranged along the moving direction of the extension arm 54;

[0066] The two displacement grooves 555 are composed of an arc groove and a straight groove, and the two straight grooves correspond to the two guide grooves 58 one by one. When the two displacement posts 556 slide along the two straight grooves, the V-shaped angle formed by the first swing arm 52 and the second swing arm 53 remains unchanged. When the two displacement posts 556 move in the two arc grooves and approach each other, the first swing arm 52 and the second swing arm 53 swing, driving the second tooling 3 and the third tooling 4 to swing and approach each other.

[0067] A transmission mechanism 57 is arranged between the first swing arm 52 and the extension arm 54; the transmission mechanism 57 includes a transmission gear 571 and a transmission rack 572. The transmission gear 571 is installed on the first swing arm 52 through an axis rotation. The transmission rack 572 is slidably arranged in a guide groove 58 on the first swing arm 52 and is connected and fixed to the displacement column 556 located in the guide groove 58. The transmission gear 571 is meshedly connected to the linear tooth portion 541.

[0068] Before the displacement drive device 55 drives the first swing arm 52 and the second swing arm 53 to swing and approach each other, the two displacement posts 556 in the displacement drive device 55 first slide in the two straight grooves and the two guide grooves 58 respectively, driving the transmission rack 572 to slide in the guide groove 58, causing the transmission gear 571 to rotate, and the extension arm 54 is driven out with the help of the linear tooth portion 541, so that the second tooling 3 and the first waste 200 are brought out; when the displacement post 556 moves to the connection between the straight groove and the arc groove, the two displacement posts 556 are respectively located on one side of the two guide grooves 58 close to the T-shaped seat 51, and then, as the two displacement posts 556 further approach each other, the two displacement posts 556 slide in the two arc grooves respectively, driving the first swing arm 52 and the second swing arm 53 to swing, thereby realizing the mutual approach of the second tooling 3 and the third tooling 4.

[0069] Through the above embodiments, the present invention, when producing the cylinder 100 for the tin melting furnace, can divide the cut whole piece of waste into two, forming a first waste 200 and a second waste 300, and can stack the first waste 200 and the second waste 300 on the top of the cutting platform 1, and then, can use the lifting device 7 to move the first waste 200 and the second waste 300 downward and distribute them under the cutting platform 1, so that the moving range of the waste is separated from the working range of the personnel, thereby enhancing the working safety; through the lifting device 7, the waste is automatically removed, which improves the convenience of removing the waste.

[0070] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
