Description

Technical Field

[0001] The utility model relates to the technical field of steel wire pay-off devices, in particular to a wire drawing and pay-off protection safety cage. Background Art

[0002] The pay-off cage is a turnover device between the wire dropper and the wire drawing machine. Its main function is to temporarily store the metal wires taken from the wire dropper and orderly transport them to the wire drawing machine for processing. In this process, the pay-off cage needs to ensure that the wires are evenly tensioned and neatly arranged to avoid entanglement or knotting of the wires, so as to ensure that the wire drawing machine can continuously and stably perform wire drawing operations.

[0003] After the existing pay-off cage has wound the wire, the wire wound on the pay-off cage usually has a high tension. The wire may rebound under the action of excessively high tension, and the wires may easily become entangled with each other, especially when the pay-off speed is fast or the pay-off is stopped, the inertia of the wire may cause it to become entangled with adjacent wires. Therefore, the utility model aims to provide a wire drawing and pay-off protection safety cage that can reduce the rebound of the wire wound on the pay-off cage. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a wire drawing and pay-off protection safety cage, which can reduce the rebound of the wires wound on the pay-off cage, so as to solve the problem in the prior art that the wires wound on the pay-off cage generate rebound and cause the wires to be entangled with each other.

[0005] In order to achieve the above-mentioned purpose, the utility model provides a wire drawing and unwinding protection safety cage, including a supporting part, a bearing part rotatably provided on the top of which, a winding cage and a protective cage with the same center but different radii are respectively provided on the bearing part, and the diameter of the protective cage is larger than the diameter of the winding cage; a tightening part, which is arranged between the winding cage and the protective cage; and a tightening mechanism, which is arranged between the tightening part and the bearing part, and drives the tightening part to move relative to the bearing part to reduce the distance between the tightening part and the winding cage.

[0006] Optionally, the clamping mechanism includes a sliding part, an elastic unit and a guiding part, a sliding groove is provided on the supporting part along its diameter direction, the sliding part is slidably arranged in the sliding groove, the guiding part is arranged in the sliding groove and passes through the sliding part, the bottom of the clamping part is connected to the sliding part, the elastic unit is arranged in the sliding groove and elastically abuts against the sliding part.

[0007] Optionally, the abutting portion is provided with a plurality of friction increasing portions at intervals along its length direction.

[0008] Optionally, a second friction increasing portion is provided at the bottom of the support portion.

[0009] Optionally, a limiting portion is provided on the top of the winding cage.

[0010] Optionally, a hook block is provided on the top of the limiting portion, and a hanging hole is provided on the hook block.

[0011] Compared with the prior art, the utility model provides a wire drawing and wire laying protection safety cage, which has the following beneficial effects:

[0012] The utility model uses a tightening mechanism to move the tightening part relative to the base so that the tightening part abuts against the wire until the wire is pressed against the winding part. When the wire drawing machine pulls the wire, the tightening part maintains the abutting pressure on the wire to suppress the tension of the wire and maintain its stable release, thereby preventing the wire from being entangled or knotted due to excessive rebound.

[0013] The utility model provides a friction increasing part. When the wire is wound on the winding cage and pressed by the pressing part, the friction increasing part increases the friction between the wire and the pressing part to prevent the wire from slipping when the wire is pulled by the wire drawing machine, thereby improving the stability of the wire unwinding process.

[0014] The utility model provides a limiting part, which can prevent the wire from slipping off or shifting from the winding cage during the winding process of the wire. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Example: See Figures 1 to 6 According to an embodiment of the utility model, a technical solution is provided: a wire drawing and unwinding protection safety cage, comprising a supporting portion 1, a bearing portion 2 is rotatably provided on the top thereof, a winding cage 3 and a protective cage 4 with the same center but different radii are provided on the bearing portion 2, and the diameter of the protective cage 4 is larger than the diameter of the winding cage 3; a tightening portion 5, which is arranged between the winding cage 3 and the protective cage 4; and a tightening mechanism 6, which is arranged between the tightening portion 5 and the bearing portion 2, and drives the tightening portion 5 to move relative to the bearing portion 2 to reduce the distance between the tightening portion 5 and the winding cage 3.

[0024] When the wire drawing and unwinding protection safety cage with the above structure is used, when the user needs to perform wire drawing operations, first, the wire is coiled on the winding cage 3. At this time, the clamping part 5 is moved relative to the base through the clamping mechanism 6, so that the clamping part 5 abuts against the wire until the wire is pressed against the winding part. After the wire drawing machine pulls the wire, the clamping part 5 maintains the abutting pressure on the wire to suppress the tension of the wire and maintain its stable release, thereby preventing the wires from being entangled or knotted due to excessive rebound.

[0025] It should be noted that as the wire is continuously pulled by the wire drawing machine, the pressing mechanism 6 can automatically adjust the pressing force of the pressing portion 5 according to the changes in the wire diameter, thereby ensuring that the wire is evenly stressed during the entire wire drawing process.

[0026] In this embodiment, the clamping mechanism 6 includes a sliding portion 7, an elastic unit 8 and a guide portion 9. A sliding groove 10 is provided on the support portion 1 along its diameter direction. The sliding portion 7 can be slidably arranged in the sliding groove 10. The guide portion 9 is arranged in the sliding groove 10 and passes through the sliding portion 7. The bottom of the clamping portion 5 is connected to the sliding portion 7. The elastic unit 8 is arranged in the sliding groove 10 and elastically abuts the sliding portion 7. When the wire is wound on the winding portion, the elastic unit 8 will elastically press the sliding portion 7 to move the sliding portion 7 along the length direction of the sliding groove 10 until the sliding portion 7 abuts against the wire on the winding cage 3. At the same time, during the movement of the sliding portion 7, the movement of the sliding portion 7 is performed on the guide portion 9 to ensure that the sliding portion 7 moves along a predetermined path to reduce or eliminate possible displacement or vibration of the sliding portion 7 during movement.

[0027] In order to effectively control the position and tension of the wire during the wire drawing process, in this embodiment, the tightening portion 5 is provided with a plurality of friction increasing portions 11 at intervals along its length direction; when the wire is coiled on the winding cage 3 and pressed by the tightening portion 5, the friction increasing portion 11 will increase the friction between the wire and the tightening portion 5 to prevent the wire from slipping when subjected to the pulling force of the wire drawing machine, thereby improving the stability of the wire unwinding process.

[0028] In order to increase the friction between the support part 1 and the horizontal surface, in this embodiment, a friction increasing part 12 is provided at the bottom of the support part 1; when the support part 1 contacts the horizontal surface, the friction increasing part 12 increases the friction between the support part 1 and the horizontal surface to prevent the support part 1 from shaking during the wire drawing operation.

[0029] In this embodiment, a limiting portion 13 is provided on the top of the winding cage 3 ; during the winding process of the wire, the limiting portion 13 prevents the wire from slipping off or shifting from the winding cage 3 .

[0030] In this embodiment, a hook block 14 is provided at the top of the limiting portion 13, and a lifting hole 15 is provided on the hook block 14; when the user needs to move the device, the user can lift the device by passing the hook of the crane through the lifting hole 15, so as to facilitate the user to move the device.

[0031] Working principle: When the user needs to perform wire drawing, first, the wire is coiled on the winding cage 3. At this time, the elastic unit 8 will elastically press against the sliding part 7, so that the sliding part 7 moves along the length direction of the sliding groove 10 until the sliding part 7 abuts against the wire on the winding cage 3, so that the pressing part 5 abuts against the wire until the wire is pressed against the winding part. After the wire drawing machine pulls the wire, the pressing part 5 maintains the abutting pressure on the wire to suppress the tension of the wire and maintain its stable release, so as to prevent the wire from being entangled or knotted due to excessive rebound; when the wire is coiled on the winding cage 3 and pressed by the pressing part 5 The friction increasing part 11 will increase the friction between the wire and the pressing part 5 to prevent the wire from slipping when subjected to the pulling force of the wire drawing machine, thereby improving the stability of the wire-releasing process; when the support part 1 is in contact with the horizontal surface, the friction increasing part 12 will increase the friction between the support part 1 and the horizontal surface to prevent the support part 1 from shaking during the wire drawing operation; when the wire is being coiled, the limiting part 13 will prevent the wire from slipping off or shifting from the winding cage 3; when the user needs to move the device, the user can lift the device by passing the hook of the crane through the lifting hole 15, so that the user can move the device easily.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
