Description

Technical Field

[0001] The utility model relates to the technical field of copper wire processing devices, in particular to an automatic correction device for a cold-drawn copper wire die. Background Art

[0002] Copper wire die refers to a tool that forces metal to pass through the die under the action of external force during metal pressure processing, compresses the metal cross-sectional area, and obtains the required cross-sectional area shape and size. The main working area of ​​the copper wire die is the inner hole, that is, the wire hole. The copper wire enters the wire drawing die from the entrance, passes through the wire drawing die under the action of the drawing force, and has severe friction on the conical surface of the wire drawing die working area. It is pulled out from the exit to obtain a thinner copper wire. The copper wire is subjected to a large extrusion friction force in the sizing area, generating a large amount of friction heat.

[0003] An automatic correction device for a cold-drawn copper wire die is disclosed in the Chinese invention patent application with the public specification CN114393049A. Although it avoids the problem of wavy bends and twisted curling of the copper wire finished product at the outlet of the wire drawing die caused by uneven force on the copper wire in the wire drawing die, and prevents the quality defects and scrap of the copper wire finished product, it is unable to correct and guide the thinner copper wire during use, and the installation between the correction sleeve and the copper wire die is relatively cumbersome. Therefore, an automatic correction device for a cold-drawn copper wire die is proposed. Utility Model Content

[0004] The utility model aims to provide an automatic correction device for a cold-drawn copper wire die to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A cold-drawn copper wire die automatic correction device comprises a correction sleeve, a correction mechanism is arranged on the outside of the correction sleeve, a mounting ring is fixedly arranged on the outside of one end of the correction sleeve, fixing plates are fixedly arranged at both ends of the mounting ring, a through groove is provided inside the fixing plate, a copper wire die is arranged on one side of the correction sleeve, a die inlet groove is provided inside the copper wire die, mounting plates are fixedly arranged on both ends of one side of the copper wire die, and a fixing mechanism is provided inside the mounting plate.

[0007] Preferably, the correction mechanism comprises a threaded barrel, a movable plate and a pressure plate, the outer side of the correction sleeve is provided with a threaded barrel through a thread, one side of the threaded barrel is inclined, both sides of the correction sleeve are movably provided with movable plates, one side of the top end of the movable plate is inclined, and one end of the movable plate is located inside the correction sleeve and fixedly provided with a pressure plate;

[0008] Preferably, a plurality of pulleys are fixedly provided at the bottom end of the pressing plate;

[0009] Preferably, limit blocks are fixedly provided on both sides of the movable plate;

[0010] Preferably, a friction pad is fixedly provided on the outer side of the threaded barrel;

[0011] Preferably, the fixing mechanism comprises an elastic groove, an elastic plate and an elastic sheet, an elastic groove is opened on one side of the top of the mounting plate, an elastic plate is arranged on one side of the elastic groove through a rotating shaft, an elastic sheet is arranged inside the elastic groove, and the elastic sheet is in contact with the elastic plate.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. By rotating the threaded barrel inward, the threaded barrel moves to one side. When the inclined surface of the threaded barrel contacts the inclined surface of the movable plate, a resistance effect will be generated, causing the movable plates at both ends to move inward until the pulleys at both ends contact the copper wire. Then, the threaded barrel stops rotating. This setting can effectively control the distance that the pressure plates and pulleys on both sides move into the correction sleeve, so that the axis of the copper wire inside the correction sleeve is unified, and copper wires of various thicknesses can be used, thereby enhancing the overall applicability.

[0014] 2. By placing the correction sleeve on one side of the copper wire mold, the mounting plate will pass through the through slot of the fixed plate, and under the elastic force of the shrapnel, the spring plate can be effectively ejected from the elastic slot, so that a conflicting fixing effect is generated between the spring plate and the fixed plate. This setting can effectively form a fixing effect between the correction sleeve and the copper wire mold, so that the copper wire can accurately enter the mold inlet slot, and this operation is relatively simple and convenient, which is convenient for the staff to operate by themselves, thereby greatly improving the overall ease of use of the equipment.

[0026] In this embodiment, preferably, a plurality of pulleys 11 are fixedly disposed at the bottom end of the pressing plate 10;

[0027] Through the above solution, the resistance between the pressing plate 10 and the copper wire is reduced, so that the copper wire can still move smoothly after being pressed;

[0028] In this embodiment, preferably, both sides of the movable plate 9 are fixedly provided with limit blocks 12;
