Description

Technical Field

[0001] The invention belongs to the technical field of bolt wire drawing and feeding, and in particular relates to a high-hardness bolt wire drawing and feeding structure and device. Background Art

[0002] The high-hardness bolt wire drawing device is an important device specially designed for processing high-strength and high-hardness bolt wires. Through the drawing process, the bolt wire is cold-processed to change its shape and enhance its mechanical properties; this process not only changes the shape of the wire, but also strengthens it through deformation to obtain higher hardness and strength. For certain materials such as medium-carbon steel and medium-carbon alloy steel, the drawing process also helps to break the lamellar cementite obtained after the wire rod is controlled cooled, preparing for the subsequent heat treatment process. During the drawing process, in order to facilitate feeding, a black drawing feeding structure is also added to the device.

[0003] The current feeding structure lacks the necessary lubrication mechanism. This defect is particularly prominent in the drawing operation, because it directly leads to a significant increase in the friction between the wire and the feeding structure. When it acts excessively during the drawing process, it will not only cause unnecessary energy loss, but also have an adverse effect on the surface quality of the wire, such as scratches, wear and even deformation, which will pose a serious threat to the subsequent processing and performance of the bolt wire. What's more serious is that excessive friction may also cause instability in the feeding mechanism, thereby affecting the continuity and stability of the entire drawing process, causing immeasurable losses to production efficiency. Summary of the invention

[0004] The purpose of the present invention is to provide a high-hardness bolt wire drawing feeding structure and device to solve the problem mentioned in the above background technology that the current feeding structure does not have the function of lubricating the bolt wire and there is excessive friction in the subsequent drawing.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a high-hardness bolt wire drawing and feeding structure, comprising two symmetrically arranged outer shells with a spacing therebetween; a support, fixed at the bottom end of the outer shell to support the outer shell; a transmission member, arranged at both ends of the outer shell, and the middle position of the transmission member is at the spacing between the two outer shells; a lubrication component; the lubrication component is located on the inner side of the transmission member, and the lubrication component is placed inside the outer shell; the lubrication component comprises: an oil tank, which is a hollow, topless rectangular structure as a whole, and through holes for the bolt wire to pass through are opened at both ends of the oil tank; a lubrication component is placed at the top position of the oil tank, and when the bolt wire passes through the oil tank, the bolt wire is lubricated by the lubrication component, thereby reducing the friction generated in the subsequent drawing process.

[0006] As a preferred technical solution in the present invention, the lubricating part is an oil injection pipe, both ends of which are outside the oil tank, while the middle part of the oil injection pipe is bent to pass through the inside of the oil tank, and a hole is opened at the bottom end surface of the bent position in the middle of the oil injection pipe. When the lubricating oil flows from one end of the oil injection pipe to the other end, part of the lubricating oil will be discharged from the middle area of ​​the oil injection pipe to achieve lubrication of the bolt wire.

[0007] As a preferred technical solution in the present invention, a support plate is also fixedly provided inside the fuel tank, and the support plate supports the middle area of ​​the fuel injection pipe to prevent the fuel injection pipe from being deviated downward as a whole.

[0008] As a preferred technical solution in the present invention, a baffle is symmetrically fixed on the inner bottom end surface of the oil tank, and a gap is left between the baffle and the inner wall of the oil tank. The top end surface of the baffle is lower than the horizontal plane of the through hole to avoid affecting the entry of the bolt wire. The vertical projection of the middle area of ​​the fuel injection pipe falls between the baffles, thereby ensuring that during lubrication, the lubricating oil mainly falls into the area of ​​the fuel injection pipe and will not be discharged to the outside of the fuel injection pipe. A sealable circular hole is provided in the middle position of the bottom of the oil tank, which is not drawn in the figure. The lubricating oil accumulated on the inner side of the baffle can be quickly discharged through the circular hole.

[0009] As a preferred technical solution in the present invention, the transmission member includes a feeding wheel arranged at one end outside the oil tank, and a discharging wheel arranged at the other end outside the oil tank.

[0010] As a preferred technical solution in the present invention, a plurality of connecting plates are further arranged between the feeding wheel and the oil tank, a scraper ring is formed in the middle position of the connecting plate, and the scraper ring is penetrated by the bolt wire. Before lubricating the bolt wire, impurities on its surface are first scraped off by the scraper ring to reduce the probability of the lubricating oil being contaminated.

[0011] As a preferred technical solution in the present invention, a collecting box is also installed at the bottom of the discharging wheel, and the bottom end of the collecting box is connected to an oil drain pipe. The lubricating oil brought out by the discharging wheel and the bolt wire is collected through the collecting box and discharged and recovered through the oil drain pipe.

[0012] The present invention also discloses a high-hardness bolt wire drawing and feeding device, including a drawing and feeding structure, a puller is arranged at the discharge direction of the shell, and a winding shaft is arranged in the discharge direction of the puller. The bolt wire is driven to rotate by the rotation of the winding shaft. At this time, the bolt wire will be pulled through the puller, and during the pulling through the puller, the surface of the bolt wire has been coated with lubricating oil, which in turn reduces the friction during the drawing.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In order to solve the problem of excessive friction in the process of drawing and feeding bolt wires, the present invention adopts an innovative solution: the feeding structure is redesigned, and a lubrication component is cleverly integrated on the basis of ensuring that its original feeding function is intact; the core of this improvement is that a set of efficient lubrication components is carefully added inside the feeding structure, which can accurately pre-lubricate the bolt wires that are about to enter the drawing process, effectively reducing the friction that may be generated in the subsequent drawing process. At the same time, the introduction of the lubrication component not only significantly improves the efficiency of the drawing operation, but also plays a vital role in ensuring the surface quality of the wire. The lubricated wire shows smoother and more stable characteristics during the drawing process, effectively avoiding scratches, wear and even deformation caused by excessive friction.

[0032] In this embodiment, the lubricating part is an oil injection pipe 201, both ends of which are located outside the oil tank 200, while the middle portion of the oil injection pipe 201 is bent to pass through the inside of the oil tank 200, and a hole is provided at the bottom end surface of the bent portion of the oil injection pipe 201.
