Description

Technical Field

[0001] The utility model relates to the field of steel cold drawing equipment, in particular to a high-precision continuous drawing device. Background Art

[0002] Cold drawn steel refers to applying tensile force to steel by a drawing device at normal temperature to break through the yield strength of the steel, so as to change the external shape of the steel and improve the internal structure of the steel. Common cold drawn steels include steel bars and steel wires, etc. The drawing device is a commonly used equipment in the cold drawing process of steel. In the existing drawing device, personnel are required to assist in clamping and fixing the steel during continuous drawing, resulting in low efficiency. Therefore, it is particularly necessary to develop a high-precision continuous drawing device that can automatically loosen and clamp the steel to improve efficiency. Summary of the Invention

[0003] The purpose of the utility model is to provide a high-precision continuous drawing device, which has the advantages of being able to automatically loosen and clamp the steel and improve the drawing efficiency.

[0004] The adopted technical solution is as follows:

[0005] A high-precision continuous drawing device includes a frame. A plurality of reducing dies are slidably arranged on the frame. Fixing mechanisms are arranged between the reducing dies and the frame. A cooling mechanism is arranged between adjacent reducing dies. A horizontal sliding mechanism is arranged at the end of the reducing die. The horizontal sliding mechanism includes a slider. A hydraulic telescopic rod connected to the slider is horizontally arranged on the frame. A three-jaw chuck is installed on the slider. A forward and reverse motor connected to the three-jaw chuck is arranged on the slider.

[0006] Preferably, the cooling mechanism includes a high-speed fan, and a protective net is arranged outside the high-speed fan.

[0007] Preferably, the horizontal sliding mechanism includes a groove, and a plurality of mutually parallel guide shafts are horizontally arranged in the groove. The sliders are all slidably connected to the guide shafts.

[0008] Preferably, a bracket is arranged at the end of the horizontal sliding mechanism, and a supporting roller is rotatably arranged at the upper end of the bracket.

[0009] Preferably, the supporting roller is a middle concave roller with a concave middle part.

[0010] Preferably, the fixing mechanism includes a slideway, the reducing die is slidably arranged in the slideway, a screw rod is threadedly connected in the slideway, and a pressing plate is rotatably arranged at one end of the screw rod close to the reducing die.

[0011] Compared with the prior art, the beneficial effects are as follows:

[0012] According to the cold drawing requirements of steel, the corresponding reducing die is aligned with the three-jaw chuck. The steel is passed through the reducing die and then inserted into the three-jaw chuck. The positive and reverse motor is used to drive the three-jaw chuck to clamp the steel. The hydraulic telescopic rod pushes the slider to move, thereby cold-drawing the steel. After the slider moves to the end, the positive and reverse motor controls the three-jaw chuck to release the steel. After the slider moves reversely to the starting point, the positive and reverse motor drives the three-jaw chuck to clamp the steel, and the hydraulic telescopic rod pushes the slider to move, thereby cold-drawing the steel, realizing continuous cold drawing without manual participation and with high efficiency.
