[0084] In the technical solution, the bracket assembly 200 is composed of two groups of brackets, which are respectively used for limiting and fixing the two ends of the special-shaped quartz pipe, of course, in order to guarantee the integrity of the bracket assembly 200, so that the driving assembly 600 can drive the bracket assembly 200 to move, and the two brackets can move synchronously to avoid the special-shaped quartz pipe from loosening, a connecting rod 230 assembly is further arranged to connect the two groups of brackets.

[0085] More specifically, the bracket is composed of two inclined supports 210, the sliding rails 110 are two and are distributed on the front and rear sides of the main rack 100, and the two inclined supports 210 are arranged on the two sliding rails 110 respectively.

[0086] The connecting rod 230 assembly comprises:

[0087] The connecting rod 230 has two ends with threaded segments, and the threaded segments of the two connecting rods 230 are arranged through the two inclined supports 210 on the same sliding rail 110 respectively.

[0089] and the connecting plates 250 are used for connecting the two ends of the two connecting rods 230, so that the inclined supports 210 can move synchronously on the sliding rails 110.

[0106] Embodiment 5:

[0107] The embodiment provides a forming equipment based on a special-shaped quartz pipe, in addition to the technical solutions of the above-mentioned embodiments, further has the following technical features.

[0108] As shown in Figure 4 In this embodiment, the torch assembly 300 includes:

[0109] The first torch 310 has two groups and is arranged on the two sides of the lower graphite wheel 420, and is used for heating the outer wall of the lower side of the special-shaped quartz pipe;

[0110] The second torch 320 is arranged on the cross beam 500 and is used for heating the inner wall of the lower side of the special-shaped quartz pipe;

[0111] The second adjusting support 330 has two groups, and the two first torches 310 are arranged on the two second adjusting supports 330, and the second adjusting support 330 is used for adjusting the angle of the first torch 310 and the distance between the first torch 310 and the special-shaped quartz pipe;

[0112] And the gas supply assembly 340 provides combustion medium for the first torch 310 and the second torch 320.

[0113] In the technical solution, in order to heat the special-shaped quartz pipe, a first burner 310 and a second burner 320 are arranged, the lower outer wall of the special-shaped quartz pipe is heated by the two groups of first burners 310, and the lower inner wall of the special-shaped quartz pipe is heated by the second burner 320.

A pressure gauge is arranged on each pipeline to detect the gas pressure in the pipeline. Hydrogen and oxygen are introduced into the burner, so that a high-temperature flame can be provided after ignition.

[0114] Since the sizes and lengths of different models of special-shaped quartz pipes are different, in order to make the temperature of each burner acting on the special-shaped quartz pipe meet the requirements, a second adjusting bracket 330 is further arranged to adjust the position of the first burner 310.

[0115] Embodiment 6:

[0116] The embodiment provides a forming equipment based on a special-shaped quartz pipe, in addition to the technical solutions of the above embodiments, and has the following technical features.

[0117] As shown in Figures 3-5 In the embodiment, the main frame 100 is provided with a first vertical beam 700 and a second vertical beam 800 located on both sides thereof, and the two ends of the cross beam 500 are arranged on the first vertical beam 700 and the second vertical beam 800 respectively.

[0118] The one end of the cross beam 500 is hingedly connected to the first vertical beam 700, and the other end is movably arranged on the second vertical beam 800. The lower end of the second vertical beam 800 is hingedly connected to the main frame 100, and the second vertical beam 800 is further provided with a locking rod 810 for limiting the rotation thereof. The second vertical beam 800 is provided with a cylinder 820 arranged in the vertical direction, and the piston rod end of the cylinder 820 extends to the cross beam 500. When the cylinder 820 works, the cross beam 500 is pushed to rotate, so as to adjust the distance between the upper graphite wheel 410 and the lower graphite wheel 420.

[0119] The second burner 320 is arranged between the upper graphite wheel 410 and the first vertical beam 700.

[0120] In the technical solution, the most core idea for the whole forming equipment is to automatically adjust the distance between the upper graphite wheel 410 and the lower graphite wheel 420. For the problem of loading and unloading the special-shaped quartz pipe, the upper graphite wheel 410 is movably arranged, and the lower graphite wheel 420 is fixed. Since the upper graphite wheel 410 is arranged on the cross beam 500, the technical problem of moving the cross beam 500 needs to be solved. For the traditional driving mode, the cross beam 500 can be arranged to move up and down, but the technical problem is how to put the special-shaped quartz pipe on the cross beam 500. After repeated modification, it is found that the cross beam 500 is hingedly connected at one end, and the other end is driven to move up and down by the air cylinder 820, which can also adjust the upper graphite wheel 410 and does not affect the rolling.

[0121] Based on this, the first vertical beam 700 and the second vertical beam 800 are arranged on the upper end surface of the main frame 100. The first vertical beam 700 is fixedly arranged, and the second vertical beam 800 is rotatably arranged. When loading and unloading the special-shaped quartz pipe, the second vertical beam 800 can be rotated. Of course, the second vertical beam 800 also needs to provide support for the special-shaped quartz pipe. Therefore, when the second vertical beam 800 is hingedly arranged, the locking rod 810 is used to lock it, and the movement of the second vertical beam 800 is limited by the locking rod. Then the air cylinder 820 is arranged on the second vertical beam 800. The piston rod end of the air cylinder 820 is opposite to the movable end of the cross beam 500. Through the movement of the air cylinder 820, the cross beam 500 is pushed up or down. The main function of the air cylinder 820 is to push the cross beam 500 up. The cross beam 500 is mainly relied on its own gravity to move down. Through its own gravity, the upper graphite wheel 410 is close to the lower graphite wheel 420, and the gravity of the cross beam 500 is enough to roll the heated special-shaped quartz pipe by the upper and lower graphite wheels 420. The movable end of the cross beam 500 is not connected with the piston rod end of the air cylinder, and the other purpose is to arrange the pressure sensor 830 on the piston rod end of the air cylinder 820. The pressure sensor 830 is used to detect the pressure of the air cylinder acting on the cross beam 500.

[0122] Further, in order to make the parts in the molding equipment simple, neat and reduce the assembly volume, the mounting seat 120 is arranged on the upper end surface of the main rack 100, the upper end of the mounting seat 120 is concave, and the shaft 121 is arranged in the mounting seat 120. Therefore, the first driven gear 630 arranged on the upper end surface of the main rack 100 is arranged on the shaft 121, and the second vertical beam 800 is arranged on the shaft of one of the mounting seats 120, thereby achieving linkage. The shaft 121 can rotate the first driven gear 630 and the second vertical beam 800. The locking rod 810 is a rod-shaped structure inserted between the second vertical beam 800 and the mounting seat 120, specifically, one end is located on the second vertical beam 800, and the other end is screwed with the mounting seat 120.

[0123] Further, when the special-shaped quartz pipe is fed or discharged, the second vertical beam 800 needs to be rotated and separated from the cross beam 500. Therefore, when the second vertical beam 800 is separated from the cross beam 500, the movable end of the cross beam 500 will move downward under the action of its own gravity, and the upper graphite wheel 410 will be in direct contact with the lower graphite wheel 420, and the upper graphite wheel 410 is supported by the lower graphite wheel 420. This way has little effect on the upper and lower graphite wheels 420 in a short time, but it will cause wear after a long time. Therefore, the hinged end of the cross beam 500 extends outward, and the ear plate 710 is arranged on the first vertical beam 700. The extension end 510 of the cross beam 500 and the ear plate 710 are connected by the threaded rod 520. The upper end of the threaded rod 520 is rotatably connected with the extension end 510, and the lower end penetrates through the ear plate 710 and is fixed by a bolt. By rotating the bolt, the distance between the upper graphite wheel 410 and the lower graphite wheel 420 can be changed. Of course, the threaded rod 520 and the bolt are only used to limit the minimum distance between the upper graphite wheel 410 and the lower graphite wheel 420, so that the upper graphite wheel 410 and the lower graphite wheel 420 are not in direct contact after the second vertical beam 800 is separated from the cross beam 500.

[0124] Specifically, the feeding mode of the special-shaped quartz pipe is as follows: the cylinder is controlled to work, so that the piston rod is retracted. During the process, the movable end of the cross beam 500 slowly moves downward, and the extended end 510 of the cross beam 500 gradually moves upward. When the nut on the threaded rod 520 gradually abuts against the bottom of the ear plate 710, the movable end of the cross beam 500 cannot move downward any more. That is to say, when the piston rod of the cylinder is separated from the cross beam 500 and before the upper graphite wheel 410 contacts the lower graphite wheel 420, the movable end of the cross beam 500 cannot continue to move downward, thereby achieving the protection of the upper graphite wheel 410 and the lower graphite wheel 420. After the movable end of the cross beam 500 cannot continue to move downward, the staff opens the locking rod 810 and rotates the second vertical beam 800. Then, the special-shaped quartz pipe can be fed.

[0131] S3, adjust the distance between the two brackets, and place the special-shaped quartz pipe between the two brackets and clamp it; then control the cylinder to work again, so that the cross beam 500 moves downward, and control the distance between the upper graphite wheel 410 and the lower graphite wheel 420;
