Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-2 As shown, this utility model is a precast rod connecting mechanism for a wire drawing tower, including a precast rod body 1 and a connecting mechanism body. The top and bottom ends of the precast rod body 1 are respectively provided with a connecting section 101 and a wire drawing cone 102.

[0025] The main body of the connecting mechanism includes a connecting plate 2, a guide plate 3, and several guide posts 4;

[0026] The top of the connecting plate 2 is provided with a clamping head 201, and the bottom of the connecting plate 2 is fixed with a fixed sleeve 202. The outside of the fixed sleeve 202 is provided with a movable sleeve 203. Both the fixed sleeve 202 and the movable sleeve 203 are half-sleeves and have mounting holes on both sides. The fixed sleeve 202 and the movable sleeve 203 are fixed to the connecting section 101 through the mounting holes and fasteners. Both the fixed sleeve 202 and the movable sleeve 203 are provided with an insert 204. The connecting section 101 is provided with a groove 103 that is clearance-fitted with the insert 204.

[0027] Several guide sleeves 205 are fixed through the edge of the connecting plate 2, and several guide posts 4 are slidably arranged in the several guide sleeves 205 and distributed parallel to the precast rod 1.

[0028] Several guide posts 4 have a counterweight ring 401 fixed at their bottom ends. The guide disk 3 is concentrically arranged inside the counterweight ring 401. Several connecting rods 402 are provided between the guide disk 3 and the counterweight ring 401. Several universal balls 403 that roll along the outer wall of the precast rod 1 are fixed on the inner wall of the guide disk 3.

[0029] It also includes a wire drawing tower clamping position, with the clamping head 201 fixed at the wire drawing tower clamping position, and several guide posts 4 set outside the wire drawing tower clamping position and not interfering with the wire drawing tower clamping position.

[0030] Among them, such as Figure 1-2 As shown, both the fixed sleeve 202 and the movable sleeve 203 are semi-cylindrical hollow sleeves, and the mounting ports on the fixed sleeve 202 and the movable sleeve 203 are T-shaped.

[0031] Among them, such as Figure 1-2 As shown, the top of the guide post 4 is provided with a limiting head 404, which is located above the connecting plate 2.

[0032] The bottom surface of the counterweight ring 401 is a planar structure, and a heat insulation layer is fixed to the bottom edge of the counterweight ring 401.

[0033] The difference in outer diameter between the fixing sleeve 202 and the precast rod 1 is greater than the depth of the groove position 103.

[0034] The working principle of this utility model is as follows: the counterweight ring 401 is pulled upward to a position close to the connecting plate 2. At this time, the fixed sleeve 202 and the movable sleeve 203 can be put on the connecting section 101. The connection between the connecting plate 2 and the precast rod 1 is realized through the installation port and fasteners. After the installation is completed, the counterweight ring 401 is lowered. The counterweight ring 401 falls with gravity and is put on the precast rod 1. The precast rod 1 is moved to the wire drawing tower clamping position for clamping.

[0035] During the wire drawing process, the wire drawing tower controls the preform 1 to move downwards and continue drawing the wire. When the counterweight ring 401 contacts the top surface of the wire drawing furnace, the continued downward movement of the preform 1 causes the guide column 4 to move upwards along the guide sleeve 205. The guide plate 3 and the universal ball bearing 403 always play a guiding and stabilizing role.
