Embodiment 1

[0039] Such as figure 1 Shown, a hardware cold drawing equipment, including:

[0040] Rack 100;

[0041] Filling assembly 200, the filling assembly 200 is arranged at the bottom of the frame 100;

[0042] A cleaning assembly 300, the cleaning assembly 300 is arranged on one side of the filling assembly 200; and

[0043] A spray assembly 400, the spray assembly 400 is arranged on the other side of the filling assembly 200;

[0044] While the cleaning component 300 is loosening the rusty surface of the steel rod conveyed in a straight line, the high-pressure air blowing is used to remove the loose rust. The coating solution and the spraying assembly 400 perform atomized spraying of the treatment solution B on the coating layer of the treatment solution A.

[0045] Through the above content, it is not difficult to find that in the process of cold drawing of hardware steel parts, it is necessary to add a lubricant to the surface of the steel rod, and then perform cold drawing af...

Embodiment 2

[0088] Such as figure 2 with 3 As shown, the components that are the same as or corresponding to those in the first embodiment are marked with the corresponding reference numerals in the first embodiment. For the sake of simplicity, only the differences from the first embodiment will be described below. The difference between the second embodiment and the first embodiment is that the cleaning assembly 300 includes:

[0089] rust scraping part 31;

[0090] A guide part 32, the guide part 32 is arranged on one side of the rust scraping part 31, and the steel rod is linearly guided through the rust scraping part 31; and

[0091] The air blowing part 33 is disposed on the other side of the rust scraping part 31 .

[0092] In this embodiment, when the cleaning assembly 300 cleans the rusted surface of the steel rod, the steel rod will transport the steel piece to the rust scraping part 31 in a straight line through the guide part 32, and the rust scraping part 31 will The rust...

Abstract

The invention provides hardware cold-drawing equipment in the technical field of hardware machining. The hardware cold-drawing equipment comprises a rack; a filling assembly arranged at the bottom of the rack, a clearing assembly arranged on one side of the filling assembly, and a spraying assembly arranged on the other side of the filling assembly, wherein the clearing assembly performs loosening treatment on the rust surface of a linearly conveyed steel rod, meanwhile, high-pressure blowing is performed to remove loosened rust, the filling assembly coats the surface and rust pits of the steel rod from the middle to the two sides along the side face of the steel rod with the treatment liquid A, and the spraying assembly performs atomization spraying of the treatment liquid B on the treatment liquid A coating layer. The hardware cold-drawing equipment has the advantages of uniform lubricant coating of a hardware steel part, complete rust surface clearing and the like.

Description

technical field [0001] The invention relates to the technical field of hardware processing, in particular to a cold drawing equipment for hardware. Background technique [0002] Cold drawing is a processing technology of materials. For metal materials, cold drawing refers to drawing under the condition that the material is at room temperature in order to achieve a certain shape and certain mechanical properties. Compared with thermoforming products, cold drawn products have the advantages of high dimensional accuracy and good surface finish. [0003] Chinese patent CN109248937B discloses a cold drawing method of nickel-chromium-iron-based high-strength superalloy rods, which belongs to the field of cold deformation technology. It solves the technical problems such as uneven structure, unstable mechanical properties, difficult forming in the cold drawing process, and low yield of the existing high-temperature alloy rods. The method includes the following steps: S1. Using vac...
