Description

Technical Field

[0001] The utility model relates to the technical field of wire pulling devices, in particular to a safety wire material pay-off rack. Background Art

[0002] Wire drawing is a mechanical operation that uses the plasticity of the material to achieve wire stretching and thinning. This process is usually called drawing, wire drawing, wire drawing or drawing.

[0003] The wire pulling operation requires a special wire pulling machine. The wire pulling machine needs to be used in conjunction with a wire pay-off stand when working. The wire pay-off stand can guide the wire when it enters the wire pulling machine. By setting several sets of guide wheels, the wire is guided so that the wire can be smoothly introduced into the wire pulling machine.

[0004] The prior art "Wire-paying support for wire drawing machine" (Announcement No.: CN215089820U) discloses a wire-paying support, which realizes the pulling of wires through guide wheels and lead wire components. However, the prior art still has the following technical problems:

[0005] Before the wire is introduced into the wire drawing machine, it needs to pass through the guide wheel of the wire pay-off rack to change the direction of the wire. When the wire is pulled to only the last section, the last section is light in weight and can easily slip off the guide wheel when being pulled. This will not only cause inaccurate direction of the wire when introduced into the wire drawing machine, affecting the quality of the wire after drawing, but also easily cause harm to the staff around the equipment, resulting in low safety. Utility Model Content

[0006] The utility model provides a safe wire pay-off stand, which can solve the problem in the prior art that the wire is easy to fall off from the guide wheel, which not only reduces the wire pulling effect, but also easily causes harm to surrounding workers and has low safety.

[0007] The present application provides the following technical solution: a safety wire pay-off stand, comprising a mounting arm, a guide component is rotatably connected to the mounting arm, and a rear end of the mounting arm is fixedly connected to a limiting portion;

[0008] The guide component includes a guide wheel rotatably connected to the mounting arm and a protective component fixed to the mounting arm, the protective component includes a positioning seat fixedly connected to the mounting arm, two support columns are fixed on the positioning seat, each support column is fixed with a circular ring, the circular ring surrounds the outside of the guide wheel, a first connecting rod is fixed between the two circular rings, the first connecting rod is located at one end of the circular ring away from the positioning seat, and a second connecting rod is fixed between a circular ring closest to the mounting arm and the mounting arm.

[0009] Beneficial effects:

[0010] The ring is fixed on the mounting arm through the support column and the positioning seat. The ring surrounds the outside of the guide wheel to protect the guide wheel. When the wire is introduced from the guide wheel, the positioning seat and the support column can limit the wire and control the wire within the space surrounded by the wheel groove of the guide wheel, the positioning seat and the support column, correcting the direction of the wire introduced into the wire drawing machine, improving the wire drawing effect, and preventing the wire from running off and slipping to injure surrounding personnel, thereby improving the safety of equipment use.

[0011] Furthermore, the guide component also includes a rotating shaft vertically fixed on the mounting arm, a bearing is installed on the rotating shaft, the guide wheel is fixed on the outer circle of the bearing, and a locking nut is threadedly connected to one end of the rotating shaft away from the mounting arm.

[0012] Beneficial effects: The guide wheel is connected to the rotating shaft through the bearing, which improves the stability of rotation, and the locking nut can prevent the guide wheel from falling off the rotating shaft.

[0013] Furthermore, the mounting arm includes a main arm and a bent arm pivoted on the main arm, the guide wheels are respectively arranged on the main arm and the bent arm, the main arm is fixed with a first connecting block and a second connecting block, the first connecting block is pivoted with a guard arm, and the other end of the guard arm is fixed to the bent arm.

[0014] Beneficial effect: Since the main arm and the bent arm are pivotally connected, the guard arm can prevent the bent arm from accidentally falling off the main arm, thereby improving the safety of the mounting arm.

[0015] Furthermore, a cylinder is pivotally connected to the second connecting block, a third connecting block is fixed to the curved arm, and an end of a piston rod of the cylinder is pivotally connected to the third connecting block.

[0016] Beneficial effect: The swing of the bending arm can be controlled by the cylinder, so that the bending arm can reach a predetermined height according to needs.

[0017] Furthermore, the limiting part includes a vertical arm fixed at the end of the bent arm, a travel switch is installed on the vertical arm, a horizontal arm is fixed at the bottom of the vertical arm, and a lead part is detachably connected to the horizontal arm.

[0018] Beneficial effect: The travel switch can limit the lead part. When the wire is entangled and knotted, the lead part will touch the travel switch, thereby stopping the equipment to prevent the knotted wire from being introduced into the wire drawing machine, causing the wire to break or causing equipment failure.

[0019] Furthermore, the lead part includes a lead tube slidably connected to the transverse arm, a trumpet-shaped limiting cage is fixed below the lead tube, a compression spring is sleeved on the lead tube rod between the limiting cage and the transverse arm, and a touch block is threadedly connected above the lead tube.

[0020] Beneficial effect: When the wire is knotted, it cannot pass through the lead tube. The knot of the wire will jam the tube mouth of the lead tube and push the lead tube to slide upward. The touch block can touch the travel switch to shut down the equipment and prevent the wire from being introduced into the wire drawing machine when it is knotted. At the same time, the trumpet-shaped limit cage can also control the swing range of the wire when it is pulled, avoiding excessive swing of the wire and accidentally injuring surrounding personnel, thereby improving the safety of equipment use.
