When the transmission pipe rotates, it drives the star-shaped turntable fixedly connected thereto to rotate together, realizing the clamping and loosening of the wire.

[0025] The steel wire passes through the transmission pipe and enters the grinding chamber, and exits from the transmission pipe at the other end of the grinding chamber. When the two chutes alternately move up and down, through the sliding connection between the chute and the sliding shaft, the two chutes drive the turntable to rotate reciprocally when alternately moving up and down, and then drive the transmission pipe fixedly connected to the turntable to rotate reciprocally, so that the wire brush wheel rotates to grind the surface of the steel wire.

[0048] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0049] Refer to Figure 1-2, as shown in Figures 6 and 8, a surface grinding device for steel wire production, including a bracket 1, the upper end of the bracket 1 is fixedly connected with a grinding chamber 2, a driving component 3 is fixedly connected inside the grinding chamber 2, two driven components 4 are slidably connected to the driving component 3, grinding components 5 are rotatably connected to the opposite sides of the two driven components 4, stress elimination components 6 are rotatably connected to the opposite sides of the two driven components 4, and clamping components 7 are fixedly connected to both ends of the grinding chamber 2; among them

[0050] The driving component 3 includes:

[0051] A motor 31, the motor 31 is fixedly installed at the upper end of the grinding chamber 2, the output end of the motor 31 is fixedly connected with a driving gear 32, the driving gear 32 meshes with a driven gear 33, the driven gear 33 is fixedly connected with one end of a lead screw 34, and the lead screw 34 is rotatably connected to the top of the inner cavity of the grinding chamber 2.

[0052] The steel wire passes through the grinding chamber 2. By starting the motor 31, the motor 31 drives the driving gear 32 fixedly connected thereto to rotate, thereby driving the driven gear 33 to rotate. The rotation of the driven gear 33 drives the lead screw 34 to rotate, thereby enabling the driven component 4 to work. Under the action of the driven component 4, the grinding component 5 rotates reciprocally to realize the reciprocating grinding of the steel wire. While reciprocating grinding, the grinding component 5 can drive the stress elimination component 6 to work to eliminate the stress generated by the steel wire during the grinding process. The starting positions of the two grinding components 5 are located in the middle of the grinding chamber 2. When the motor 31 is started, the two grinding components 5 move towards both ends of the grinding chamber 2 respectively. During this process, the stress elimination component 6 moves from the middle position of the steel wire to both ends, gradually eliminating the stress generated by the steel wire during the grinding process. When the motor 31 rotates in the reverse direction, the two grinding components 5 move from both ends of the grinding chamber 2 towards the middle to grind the steel wire. During the process of the two grinding components 5 moving towards the middle of the grinding chamber 2, the clamping component 7 clamps the steel wire, and the stress elimination component 6 moves from both ends of the steel wire towards the middle, gradually eliminating the stress during the grinding process of the steel wire.

[0053] Refer to Figure 3-4 As shown, two concave-convex slide rails 21 are fixedly connected to the top of the inner cavity of the grinding chamber 2, and the lead screw 34 is arranged between the two concave-convex slide rails 21; and

[0054] The driven component 4 includes:

[0055] Convex skateboard 41, two first springs 42 are fixedly connected to the convex skateboard 41, the two first springs 42 are arranged longitudinally, the lower ends of the two first springs 42 are fixedly connected to the convex skateboard 41, the upper ends of the two first springs 42 are fixedly connected to the lower end of the ejector rod 43, the upper end of the ejector rod 43 abuts against the concave-convex slide rail 21, the upper end of the convex skateboard 41 is slidably connected to the concave-convex slide rail 21, the lower end of the ejector rod 43 is fixedly connected to one end of the L-shaped connecting rod 44, the other end of the L-shaped connecting rod 44 is fixedly connected to one end of the connecting shaft 45, and the other end of the connecting shaft 45 is fixedly connected to one end of the chute 46.

[0056] The concave-convex parts on the two concave-convex slide rails 21 are complementary. When the lead screw 34 rotates, it pushes the convex skateboard 41 to slide on the grinding chamber 2 and the concave-convex slide rail 21, and at the same time drives the ejector rod 43, the first spring 42, the L-shaped connecting rod 44, the connecting shaft 45 and the chute 46 to move together. When the upper end of the ejector rod 43 moves to the protruding position on the concave-convex slide rail 21, the ejector rod 43 is pressed down, so that the first spring 42 is compressed, thereby driving the L-shaped connecting rod 44, the connecting shaft 45 and the chute 46 to move downward together. Since the concave-convex parts on the two concave-convex slide rails 21 are complementary, at this time, the other ejector rod 43 just moves to the concave position on the other concave-convex slide rail 21, and the other first spring 42 is in its original length. In this way, the two chutes 46 move up and down alternately.

[0057] Refer to Figure 5 As shown, two first slideways 411 are opened at the upper end of the convex skateboard 41, the concave-convex slide rail 21 slides in the first slideway 411, a connecting hole 412 is opened at the bottom of the first slideway 411, the lower end of the first spring 42 is fixedly connected to the bottom of the connecting hole 412, the ejector rod 43 is slidably connected in the connecting hole 412, a second slideway 413 is opened on one side of the convex skateboard 41, the second slideway 413 is arranged at a position corresponding to the connecting hole 412, a rotating hole 414 is opened on the convex skateboard 41, and a threaded hole is opened at the upper end of the convex skateboard 41, and the lead screw 34 is adapted to the threaded hole.

[0058] When the lead screw 34 rotates, due to the adaptation of the lead screw 34 and the threaded hole, the lead screw 34 drives the convex skateboard 41 to slide in the grinding chamber 2 when rotating.

[0059] Refer to Figure 7 As shown, the grinding assembly 5 includes:

[0060] The transmission pipe 51 is rotatably connected in the rotation hole 414 through a bearing 52. One end of the transmission pipe 51 is fixedly connected to the turntable 53. Two sliding shafts 531 are fixedly connected to one side of the turntable 53. The two sliding shafts 531 are respectively slidably connected to the two sliding grooves 46. A plurality of wire brush wheels 54 are rotatably connected to the other side of the turntable 53. The wire brush wheels 54 are fixedly connected to the first gear 55 through the first rotating shaft 56. The first rotating shaft 56 is rotatably connected to the turntable 53. The first gear 55 meshes with the toothed ring 57. The toothed ring 57 is fixedly connected to the other side of the convex-shaped slide plate 41 through a fixing rod 58.

[0061] The wire passes through the transmission pipe 51 and enters the grinding chamber 2, and exits from the transmission pipe 51 at the other end of the grinding chamber 2. When the two sliding grooves 46 alternately move up and down, through the sliding connection between the sliding grooves 46 and the sliding shafts 531, the two sliding grooves 46 drive the turntable 53 to rotate reciprocally when alternately moving up and down, and then drive the transmission pipe 51 fixedly connected to the turntable 53 to rotate reciprocally, so that the wire brush wheels 54 perform rotational grinding on the surface of the wire. At the same time, through the meshing of the first gear 55 and the toothed ring 57, while the wire brush wheels 54 rotate with the turntable 53 to grind the wire, the wire brush wheels 54 themselves rotate to grind the wire.

[0062] Refer to Figure 9 As shown in the figure, the stress relief assembly 6 includes:

[0063] A star-shaped turntable 61, the star-shaped turntable 61 is fixedly connected to the other end of the transmission pipe 51. The star-shaped turntable 61 is respectively rotatably connected to one end of a plurality of angled rods 62. The other ends of the plurality of angled rods 62 are respectively rotatably connected to a plurality of sliders 63. The plurality of sliders 63 are respectively fixedly connected to one end of a plurality of pressing rods 64; and

[0064] The slider 63 is slidably connected to the first slide rail 65. The first slide rail 65 is fixedly connected inside the protective cover 66. The protective cover 66 is fixedly connected to the other side of the convex-shaped slide plate 41.

[0065] When the transmission pipe 51 rotates, it drives the star-shaped turntable 61 fixedly connected thereto to rotate together, causing the angled rods 62 to deflect, and then driving the sliders 63 rotatably connected to the angled rods 62 to slide reciprocally on the first slide rail 65, and further causing the pressing rods 64 to slide reciprocally, realizing clamping and releasing of the wire. During the process of clamping and releasing the wire, the convex-shaped slide plate 41 is always in a moving state. Therefore, during the time period of clamping and releasing the wire instantaneously, there is a stretching effect on the wire, and the stress generated during the grinding of the wire is eliminated by stretching.

[0066] Refer to Figure 10On the left and right sides of the upper end of the described bracket 1 are respectively fixedly connected with U-shaped frames 11; and

[0067] The clamping assembly 7 includes:

[0068] A cylinder 71, the cylinder 71 is fixedly connected to the U-shaped frame 11, the output end of the cylinder 71 is fixedly connected with a hinge block 72, both ends of the U-shaped frame 11 are slidably connected with a second pressing rod 73, the second pressing rod 73 is rotationally connected with one end of a deflection rod 74, and the other end of the deflection rod 74 is hinged to the hinge block 72.

[0069] When the two convex slide plates 41 move towards each other, the cylinder 71 contracts, causing the second pressing rods 73 to move towards each other to clamp the steel wire. During the reciprocating movement of the pressing rods, the steel wire is clamped and released. With the cooperation of the clamping action of the deflection rods 74 at both ends of the steel wire, the stress of the steel wire is eliminated from both ends to the middle.

In the description of the present invention, unless otherwise specified and limited, it should be noted that the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a mechanical connection or an electrical connection, or it can be the communication inside two elements. It can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms can be understood according to specific circumstances.

[0071] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention.
