Description

A drawing machine for machining hexagonal metal bars Technical Field

[0001] This utility model relates to the field of hexagonal bar processing, and in particular to a drawing machine tool for processing metal hexagonal bars. Background Technology

[0002] In traditional techniques, during the drawing process of hexagonal bars, the internal stress of the metal hexagonal bars may be uneven during the raw material stage. Therefore, when drawing, this internal stress will affect the deformation of each surface under the action of drawing force. For example, the surface of the hexagonal bar corresponding to the area with higher internal stress may be more easily deformed during the drawing process, while the area with lower stress will deform relatively less. This will lead to inconsistent force on each surface, which will easily cause irregular hexagonal cross-sections, with some corners being too large and others too small. As a result, some of the finished hexagonal bars will have poor quality. Summary of the Invention

[0006] The processing assembly includes a fixing plate fixed to one side of the resistance heater, and three sets of grinding components one and three sets of grinding components two are respectively fixed to one side of the fixing plate. The fixing plate has hexagonal grooves.

[0007] The three sets of grinding components one and three sets of grinding components two have the same structure, the only difference being the arrangement angle, and the three sets of grinding components one and three sets of grinding components two are respectively arranged at each plane position of the hexagonal bar.

[0008] Preferably, the grinding component includes a rotary motor fixed to one side of a fixed plate, and a grinding wheel is fixed to the output end of the rotary motor via a connecting rod.

[0026] Referring to Figures 1-5, a drawing machine tool for processing hexagonal metal bars includes: a base 1, a driving component 2 fixed to the upper side of the base 1, a resistance heater 3 disposed on one side of the driving component 2, and a processing assembly 4 fixed to one side of the resistance heater 3; wherein

[0027] The processing assembly 4 includes a fixing plate 41 fixed to one side of the resistance heater 3. Three sets of grinding components 42 and three sets of grinding components 43 are respectively fixed to one side of the fixing plate 41. A hexagonal groove 44 is provided on the fixing plate 41.

[0028] The three sets of grinding components 1 42 and the three sets of grinding components 2 43 have the same structure, the only difference being the arrangement angle. The three sets of grinding components 1 42 and the three sets of grinding components 2 43 are respectively arranged at various plane positions of the hexagonal bar.

[0029] The grinding component 42 includes a rotary motor 421 fixed to one side of the fixed plate 41, and a grinding wheel 422 is fixed to the output end of the rotary motor 421 via a connecting rod.

[0030] A hexagonal bar is in contact with one side of the grinding wheel 422.

[0031] The inner wall of the hexagonal groove 44 on the fixed plate 41 is in an extrusion relationship with the hexagonal bar.

[0032] The driving component 2 includes a slide groove 21 and a cylinder 22 fixed to the upper side of the base 1. A push block 23 is fixed to the output end of the cylinder 22 via a piston rod.

[0033] The upper sidewall of the slide 21 is in close contact with the hexagonal bar.

[0034] One side of push block 23 is in contact with a hexagonal bar.

[0035] Working principle: Please refer to Figures 1-5. First, in this embodiment, a metal hexagonal bar drawing machine tool is used to place the metal hexagonal bar to be processed on the slide groove 21. At the same time, the hexagonal bar moves forward continuously under the push of the cylinder 22. Meanwhile, the upper side wall of the slide groove 21 keeps in close contact with the hexagonal bar, which plays a role in positioning and guiding.

[0036] The drive component 2 is activated. The cylinder 22 pushes the push block 23 via the piston rod. One side of the push block 23 contacts the hexagonal bar, applying a forward thrust to the hexagonal bar. Simultaneously, the resistance heater 3 begins to heat the hexagonal bar to be processed, softening the metal to facilitate subsequent drawing and grinding. (The resistance heater 3 is a conventional technique in the prior art, and will not be described in detail here, nor will the accompanying drawings show it in detail.)

[0037] When the hexagonal bar is pushed to the processing component 4, its hexagonal groove 44, through the cylinder 22 in the drive component 2, drives the pusher block 23 via the piston rod. One side of the pusher block 23 contacts the hexagonal bar, thus applying a forward thrust to the hexagonal bar to be processed. This forces the softened metal of the hexagonal bar to be processed through a compression, allowing it to slowly and steadily pass through the processing area and continue to be pushed out. The three sets of grinding components 1 42 and 3 sets of grinding components 2 43 begin to work. The rotary motor 421 drives the grinding wheel 422 to rotate, and one side of the grinding wheel 422 contacts the various planar positions of the hexagonal bar. Since the three sets of grinding components 1 42 and 3 sets of grinding components 2 43 are respectively arranged at the various planar positions of the hexagonal bar, all six faces of the hexagonal bar can be ground simultaneously. Although the grinding components 1 42 and 2 43 have the same structure, their arrangement angles are different, ensuring the comprehensiveness and uniformity of the grinding. After the hexagonal bar passes through the entire processing area, all six sides of it have been uniformly ground to the required size and surface finish.

[0038] At this point, shut off cylinder 22 and resistance heater 3, and remove the processed hexagonal bar.
