Description

Technical Field

[0001] The utility model relates to the technical field of refrigerator grid production, in particular to a steel wire flattening feeding device. Background Art

[0002] Storage racks for refrigerators and freezers are generally made of bent and welded steel wires. Some products are processed with flat steel according to customer needs. Flat steel is usually pressed from round steel wire. During the pressing process of the flat steel, radial compressive stress will be generated inside it. Radial compressive stress refers to the stress state on the unit cross section of the deformed body in the plastic deformation zone when the metal is squeezed. The residual stress inside the flat steel will put it in an unstable state, causing stress creep, or reaching the yield limit of the metal material under very small external loads, causing deformation or cracking. Therefore, stress relief work will be performed after the flat steel is processed.

[0003] At present, the industry generally adopts heat treatment method to eliminate stress of flat steel, but the flat steel processing equipment itself does not have heat treatment function. Therefore, after the flat steel is processed, it needs to be transferred to heat treatment equipment for heat treatment, which reduces the processing efficiency of flat steel. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] It should be noted that all directional indications (such as up, down, left, right, front, back...) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0024] In the description of the embodiments, unless otherwise clearly specified and limited, the terms "disposed", "connected" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection, or an electrical connection; it can be a direct connection, or it can be connected through an intermediate medium, or it can be a communication between two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0025] like Figure 1 As shown, the steel wire flattening and unloading device in this embodiment includes a workbench 1 and an unwinding bracket 2, a guide roller 3, a flattening mechanism 4, a traction mechanism 5, a cutting mechanism 6 and a vibration mechanism 7 arranged on the workbench 1. An unwinding motor 8 is provided on one side of the unwinding bracket 2. The unwinding motor 8 is transmission-connected to the steel wire coil on the unwinding bracket 2, thereby driving the steel wire coil to operate and realizing the unwinding work of the steel wire.

[0026] The guide roller 3 is placed on the rear side of the unwinding bracket 2, the flattening mechanism 4 is arranged on the rear side of the guide roller 3, the traction mechanism 5 is arranged on the rear side of the flattening mechanism 4, the cutting mechanism 6 is arranged on the rear side of the traction mechanism 5, and the vibration mechanism 7 is arranged on the rear side of the cutting mechanism 6; after the steel wire comes out of the unwinding bracket 2, it passes through the guide roller 3, the flattening mechanism 4, the traction mechanism 5, the cutting mechanism 6 in sequence, and finally enters the vibration mechanism 7.

[0027] like Figure 2As shown, a groove 31 for the steel wire to pass through is provided on the circumferential surface of the guide roller 3, which plays a role in guiding the steel wire and preventing it from running off.

[0028] The flattening mechanism 4 includes an upper pressure roller 41, a lower pressure roller 42, an upper gear 43, a lower gear 44 and a flattening motor 45. The upper pressure roller 41 and the lower pressure roller 42 are relatively arranged above the workbench 1 through a flattening bracket 46. The upper gear 43 is coaxially arranged at one end of the upper pressure roller 41, and the lower gear 44 is coaxially arranged at one end of the lower pressure roller 42. The flattening motor 45 is arranged on one side of the flattening bracket 46 and is transmission-connected to the upper pressure roller 41 or the lower pressure roller 42.

[0029] The flattening motor 45 drives the upper pressing roller 41 or the lower pressing roller 42 to rotate, and the other sides of the two pressing rollers are driven by the upper gear 43 and the lower gear 44. The steel wire passes between the upper pressing roller 41 and the lower pressing roller 42 and is pressed into flat steel by the two pressing rollers.

[0030] like Figure 3 As shown, the traction mechanism 5 includes a traction motor 51 and two traction wheels 52. The bottom of the traction motor 51 is set on the workbench 1, and a mounting plate 53 is provided on the top. One of the traction wheels 52 is connected to the main shaft of the traction motor 51, and the other traction wheel 52 is rotatably set on one side of the main shaft through the mounting plate 53. A clamping groove 54 is provided at the middle ring position of the traction wheel 52.

[0031] The traction motor 51 drives one of the traction wheels 52 to rotate, and the flat steel is clamped by the clamping groove 54 between the two traction wheels 52 for transportation. The traction wheel 52 can be made of rubber material, or a steel wheel with a rubber material coated on the surface, so as to avoid clamping the flat steel.

[0032] The cutting mechanism 6 includes a cutting cylinder 61, a cutting knife 62 and a cutting seat 63. The cutting seat 63 is arranged on the workbench 1. The cutting cylinder 61 is arranged above the cutting seat 63 through a cutting bracket 64. The cutting knife 62 is arranged at the end of the piston rod at the lower end of the cutting cylinder 61. Figure 4 As shown, a knife groove 65 is provided at a position on the top of the cutting seat 63 corresponding to the cutting knife 62 .

[0033] When the pressed flat steel passes through the cutting mechanism 6 , the cutting cylinder 61 drives the cutting knife 62 to move downward to cut off the flat steel on the cutting seat 63 .

[0034] like Figure 5 As shown, the vibration mechanism 7 includes a material receiving box 71 and a vibration motor 72 . A positioning groove 11 is provided on the workbench 1 . The vibration motor 72 is arranged at the bottom of the positioning groove 11 . The material receiving box 71 is arranged in the positioning groove 11 and the bottom is in contact with the vibration motor 72 .

[0035] The cut flat steel is pushed into the receiving box 71 by the flat steel delivered subsequently, and the vibration motor 72 drives the receiving box 71 to vibrate, thereby driving the flat steel inside the receiving box 71 to vibrate.

[0036] The vibration process causes the flat steel to undergo plastic deformation. When the additional stress σdynamic is superimposed on the residual stress σresidual and reaches or exceeds the yield limit σs of the material, that is, σdynamic + σresidual ≥ σs, the flat steel undergoes microscopic or macroscopic plastic deformation, thereby reducing and homogenizing the residual stress in the flat steel. There is no need for subsequent heat treatment, which improves the processing efficiency of the flat steel.

[0037] The above is only a preferred embodiment of the utility model, and is not intended to limit the utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in the field to implement; when the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the utility model.
