Description

Technical Field

[0002] Cold drawing is a material processing technology. For metal materials, cold drawing refers to drawing or extruding the material at room temperature in order to achieve a certain shape and certain mechanical properties. Compared with hot forming, cold-drawn products have the advantages of high dimensional accuracy and good surface finish, small deformation of sizing, and relatively large springback of steel pipe after rolling. Compared with the diameter reduction process with large reduction, the flow and stress distribution of metal in the steel pipe are more sensitive to the changes of parameters such as roll shape and reduction, which makes it more difficult to calculate rolling pressure and reduction using classical analytical methods. The processing of some special workpieces requires the use of cold drawing and sizing equipment for processing and production.

[0029] In this embodiment, a feed hole 8 and a discharge hole 9 are respectively provided at the left and right ends of the second limiting tube 6. The diameter of the discharge hole 9 is smaller than the diameter of the feed hole. By setting the feed hole 8 and the discharge hole 9, the pipe can be cold drawn through the feed hole 8 and the discharge hole 9.

[0030] In this embodiment, the driving mechanism 5 includes a fixing plate 51 fixedly mounted on the upper surface of the mounting plate 1 and a hydraulic cylinder 52 fixedly mounted on the right surface of the fixing plate 51. By setting the hydraulic cylinder 52, the user can start the hydraulic cylinder 52 to drive the first mounting column 2 to move.

[0031] In this embodiment, the axis of the second limiting tube 6 and the first limiting tube 41 are located in the same plane position, and the first gear 46 is meshed with the first rack 45. In order to increase the clamping effect, the number of the first gears 46 is two, and the two first gears 46 are respectively located on the front and rear sides of the first rack 45.

[0032] In this embodiment, a slide groove is provided in the mounting plate 1, and the first mounting column 2 is slidably connected to the slide groove. By providing the slide groove, the movement of the first mounting column 2 can be slidably limited.
