DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0026] Embodiment 1

[0027] Please see attached Figure 1-3

[0028] A support frame 1, a placement frame 2 and a positioning plate 3, wherein the support frame 1 is provided with a concave groove 10, the placement frame 2 is convex, and is provided with at least one set of position locking components 4, and the placement frame 2 is slidably connected in the concave groove 10, the positioning plate 3 is fixedly connected to the placement frame 2 through a plurality of connecting ribs 20, and the positioning plate 3 and the placement frame 2 together form a placement cavity 5;

[0029] The placement cavity 5 formed by the placement rack 2 and the positioning plate 3 can be used to place the blow pipe. Considering that the blow pipe is generally long and exceeds the working area of ​​the punching machine, the sliding connection between the placement rack 2 and the support rack 1 is utilized to achieve the purpose of moving the blow pipe, thereby realizing the purpose of punching holes in the blow pipe.

[0030] Specifically, the position locking assembly 4 includes a position locking block 40 and a turning handle 41, one of the edges of the position locking block 40 is hinged on the top wall of the placement rack 2, the turning handle 41 is located on the outside of the placement cavity 5, and one end of the turning handle 41 is fixedly connected to the side wall of the locking block 40; in order to prevent the blow pipe from moving over a large range during welding and punching, the blow pipe is fixed by the position locking block 40 and the turning handle 41. In the process of placing the blow pipe into the placement cavity 5 by using a crane, the turning handle 41 is first used to drive the position locking block 40 to rotate, so that the position locking block 40 is in a state where the blow pipe is not locked, that is, the short side of the position locking block 40 is vertical to the top wall of the placement rack 2. After the blow pipe is placed in the placement cavity 5, the position locking block 40 is used to complete the locking of the blow pipe, that is, the long side of the position locking block 40 is vertical to the top wall of the placement rack 2.

[0031] Specifically, the position locking block 40 is rectangular and is provided with an arc-shaped contact surface 400 ; the arc-shaped contact surface 400 on the locking block 40 is provided to make it fit more closely to the curved side wall of the blowing tube, thereby achieving a better fixing effect.

[0032] Embodiment 2

[0033] Please see attached Figure 4

[0034] The position locking assembly 4 includes a cylinder 43 and a contact block 44, wherein the cylinder 43 is fixedly connected to the placement rack 2, and the piston rod of the cylinder 43 passes through the top wall of the placement rack 2 and is fixedly connected to the contact block 44;

[0035] Considering that the rectangular position locking block 40 has a fixed length of its long side, it means that it is for the same specification of blow pipes. When it is necessary to weld blow pipes of different specifications, the matching position locking component 4 must be replaced. When it is necessary to weld blow pipes of multiple specifications in small batches, the position locking component 4 will be frequently replaced, and there may even be a need to customize the position locking component 4. In order to further improve the efficiency, a cylinder 43 is installed inside the placement frame 2, and the telescopic rod of the cylinder 43 is connected to the contact block 44 in the placement cavity 5, so as to achieve the purpose of freely changing the position of the contact block 44, thereby achieving the purpose of completing the position locking for blow pipes of different specifications.

[0036] Embodiment 3

[0037] Please see attached Figure 5-6

[0038] At least one set of mounting grooves 100 is disposed on the bottom wall of the concave groove 10 , and a sliding roller 101 connected to the groove wall by a bearing is disposed in the mounting groove 100 .

[0040] In order to reduce the resistance when pushing the placement rack 2 to slide in the support rack 1, a sliding roller 101 is set in the concave groove 10 to assist the movement of the placement rack 2. At the same time, considering that the moving distance of the placement rack 2 each time should not exceed the coverage range of the puncher, a limit plate 102 is set to limit the movement of the placement rack 2 to avoid the situation where the placement rack 2 moves too far and escapes from the coverage range of the puncher.

[0042] Please see attached Figure 7

[0043] Specifically, the positioning plate 3 is provided with a plurality of groups of penetration holes 30;

[0044] In order to further fix the position of the blow pipe and prevent it from rotating in the placement cavity 5, a through hole 30 is opened on the positioning plate 3. The position of the through hole 30 is matched with the position of the short tube on the blow pipe. While fixing the blow pipe, the position of the short tube on the blow pipe can be checked.

[0045] Specifically, the positioning plate 3 is provided with a strip groove 31, and a plurality of positioning components 32 movably connected thereto are provided in the strip groove 31, and the positioning components 32 include a rectangular plate 320, an elastic telescopic rod 321 and a positioning block 322, and the two ends of the elastic telescopic rod 321 are respectively fixedly connected to the rectangular plate 320 and the positioning block 322, and the rectangular plate 320 and the positioning block 322 are respectively in contact with the side wall of the strip groove 31;

[0046] Taking into account that the positions of the short sides of the blowing tubes of different specifications are not exactly the same, in order to achieve the purpose of appropriately adjusting the position of the penetration hole 30 according to the position of the short tube, the setting of the positioning component 32 is adopted, and the elastic telescopic rod 321 can be used to freely retract and retract, so as to easily achieve the purpose of disassembling the positioning component 32 in the strip groove 31. It should be noted that the elastic telescopic rod 321 is in a compressed state when it is located in the strip groove 31. At the same time, according to actual conditions, the rectangular plate 320 and the positioning block 322 can be provided with a penetration hole 30 that matches the short tube on the blowing tube. In order to further ensure that the positioning component 32 will not fall or be pushed against the strip groove 31 when it is located in the strip groove 31, anti-skid stripes can be provided on the contact surface between the rectangular plate 320 and the positioning block 322 and the strip groove 31, or the friction can be increased by adopting an uneven contact surface, or a special slide groove can be provided on the contact surface between the strip groove 31 and the rectangular plate 320 and the positioning block 322.
