Description

Technical Field

[0001] The utility model relates to the technical field of cold drawing processing, in particular to a device for improving the surface finish of cold drawn wire. Background Technique

[0002] Cold drawn wire is a kind of metal cold processing. The raw material is wire rod, which is the steel bar we often mention. It is a product produced through a series of processes such as shelling. Cold drawn wire is used more in building materials, and the detection standards of cold drawn wire are also different. Cold drawn wire has high strength and can be used in many aspects. The most used is prestressed tendon. In occasions where plasticity is not required and only strength is required, such steel can be used;

[0003] It is very difficult to ensure that the surface finish of the currently produced cold drawn wire meets the standard, and during the grinding process, the grinding is not sufficient, generating a large amount of debris that needs to be cleaned by workers, which is time-consuming and laborious and increases the workload. Content of the Utility Model

[0004] In order to solve the problems of insufficient surface grinding and low finish of cold drawn wire during the grinding process; the purpose of the utility model is to provide a device for improving the surface finish of cold drawn wire.

[0005] To solve the above technical problems, the utility model adopts the following technical scheme: A device for improving the surface finish of cold drawn wire, including a grinding box. Two groups of symmetrically distributed fixed columns are fixedly arranged on the inner wall of the grinding box. A bearing is jointly arranged on the opposite sides of the two groups of fixed columns. Two identical grinding rollers are arranged on the opposite sides of the two bearings. The two grinding rollers are fixedly connected to the inner ring of the bearing and a second gear is jointly fixedly connected to the opposite sides. A second fixed sleeve is fixedly connected to the inner wall of the grinding box. A second motor is fixedly arranged inside the second fixed sleeve. The output end of the second motor is fixedly connected to a first connecting column. One end of the first connecting column away from the second motor is fixedly connected with a third gear meshing with the second gear.

[0006] Preferably, a transmission box is fixedly arranged at the center of the side of the grinding box away from the fixed column. Two symmetrically distributed first rotating shafts penetrate through the top of the transmission box. First gears are fixedly arranged near the top ends of the two first rotating shafts. The two first gears are meshed with each other. Transmission wheels are symmetrically distributed inside the transmission box. The two first rotating shafts respectively penetrate through the transmission wheels.

[0005]

[0007] Compared with the prior art, the beneficial effect of the utility model lies in:

[0008] 1. In the present utility model, the third gear is driven by the second motor to rotate, driving the second gear to rotate, so that the grinding roller connected to the second gear rotates, thereby fully grinding the surface of the cold-drawn wire, improving the surface finish of the cold-drawn wire, and at the same time reducing the workload of the staff, which is more simple and convenient.

[0009] 2.

[0017] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0018] Embodiment: As Figures 1-5 shown, the present invention provides a device for improving the surface finish of cold-drawn wire, including a grinding box 1. Two groups of symmetrically distributed fixed columns 4 are fixedly arranged on the inner wall of the grinding box 1. A bearing 41 is jointly arranged on the opposite sides of the two fixed columns 4. Two identical grinding rollers 42 are arranged on the opposite sides of the two bearings 41. The two grinding rollers 42 are fixedly connected to the inner ring of the bearing 41 and a second gear 43 is jointly fixedly connected to the opposite sides. A second fixed sleeve 46 is fixedly connected to the inner wall of the grinding box 1. A second motor 47 is fixedly arranged inside the second fixed sleeve 46. The output end of the second motor 47 is fixedly connected to a first connecting column 45. A third gear 44 meshing with the second gear 43 is fixedly connected to the end of the first connecting column 45 away from the second motor 47.

[0019] A transmission box 2 is fixedly arranged at the center of the side of the grinding box 1 away from the fixed column 4. Two symmetrically distributed first rotating shafts 22 penetrate through the top of the transmission box 2 in a rotating manner. First gears 23 are fixedly arranged near the top ends of the two first rotating shafts 22. The two first gears 23 are meshed and connected. Symmetrically distributed transmission wheels 24 are arranged inside the transmission box 2. The two first rotating shafts 22 respectively penetrate through the transmission wheels 24 fixedly; a second limiting ring 21 is fixedly arranged at the center of the side of the transmission box 2 away from the grinding box 1. A first limiting ring 12 is fixedly arranged on the side of the grinding box 1 away from the grinding box 1. The first limiting ring 12 and the second limiting ring 21 are symmetrically distributed; a first motor 3 is coaxially and fixedly installed at the top of the first rotating shaft 22. A first fixed sleeve 31 is fixedly arranged on the side of the first motor 3. The first fixed sleeve 31 is fixedly connected to the side of the grinding box 1; the staff passes the cold-drawn wire through the first limiting ring 12. As the first motor 3 starts, it drives the first rotating shaft 22 to rotate. Under the action of the first gear 23, the two first rotating shafts 22 drive the transmission wheels 24 to rotate towards each other, driving the cold-drawn wire to move, and at the same time restricting the position of the cold-drawn wire through the first limiting ring 12, thereby achieving the effect of limiting transmission.

[0020] Inside the grinding box 1, near the first motor 3, there are limit posts 6 distributed in a triangular shape. A semi-circular groove 65 is formed on the surface of the limit post 6. At the center of the three limit posts 6, a second rotating shaft 61 is fixedly arranged. The three second rotating shafts 61 rotate through the grinding box 1, and the end far from the limit post 6 is connected with a driving device; the driving device includes the second rotating shaft 61. At the bottom of one side of the grinding box 1, a second fixing block 71 is fixedly connected. On the top of the second fixing block 71, a third fixing sleeve 72 is fixedly arranged. Inside the third fixing sleeve 72, a third motor 7 is fixedly arranged. The output end of the third motor 7 is fixedly connected with a second connecting column 73. The end of the second connecting column 73 far from the third motor 7 is fixedly connected with a seventh gear 74. On the side surfaces of the three second rotating shafts 61 near the third motor 7, a fourth gear 62, a fifth gear 63, and a sixth gear 64 are respectively fixedly arranged. The fourth gear 62 is located at the top. The fourth gear 62 and the fifth gear 63 are meshed and connected. The fifth gear 63 and the sixth gear 64 are jointly meshed on both sides of the seventh gear 74; the cold-drawn wire is transmitted into the semi-circular groove 65 formed on the surface of the limit post 6. Due to the drive of the third motor 7, the second connecting column 73 and the seventh gear 74 are driven to rotate, so that the fifth gear 63 and the sixth gear 64 meshed with the seventh gear 74 rotate in the same direction, and the fourth gear 62 meshed with the fifth gear 63 rotates in the opposite direction, so that the three limit posts 6 rotate together, thereby driving the cold-drawn wire to move forward, and achieving the effects of slight grinding and limiting and straightening.

[0021] A collection box 5 is slidably arranged at the bottom of the grinding box 1. At the bottom of one side of the grinding box 1 far from the third motor 7, a first fixing block 11 is fixedly connected; a T-shaped pulling block 51 is fixedly connected to the side of the collection box 5 far from the grinding box 1. A pin 52 is jointly arranged through the T-shaped pulling block 51 and the first fixing block 11; when it is necessary to clean the debris, the pin 52 is pulled out, and by pulling the T-shaped pulling block 51, the collection box 5 can slide at the bottom of the grinding box 1. When it is necessary to fix, the pin 52 is inserted into the T-shaped pulling block 51 and the first fixing block 11 to achieve the fixing effect, so as to collect the debris generated during the grinding process.

[0022] Working principle: First, the staff thread the cold-drawn wire through the first limiting ring 12. As the first motor 3 starts, it drives the first rotating shaft 22 to rotate. Under the action of the first gear 23, the two first rotating shafts 22 drive the transmission wheels 24 to rotate towards each other, driving the cold-drawn wire to move. At the same time, the position of the cold-drawn wire is restricted by the first limiting ring 12, thus achieving the effect of limiting and driving. Subsequently, the cold-drawn wire is transmitted into the semi-circular groove 65 opened on the surface of the limiting column 6. Due to the drive of the third motor 7, the second connecting column 73 and the seventh gear 74 rotate, causing the fifth gear 63 and the sixth gear 64 meshing with the seventh gear 74 to rotate in the same direction, and causing the fourth gear 62 meshing with the fifth gear 63 to rotate in the opposite direction, so that the three limiting columns 6 rotate together, thereby driving the cold-drawn wire to move forward and achieving the effect of slight grinding and limiting straightening. Then, through the grinding roller 42, the second motor 47 drives the first connecting column 45 and the third gear 44 to rotate, driving the second gear 43 meshing with the third gear 44 to rotate, so that the grinding roller 42 connected to the second gear 43 rotates to fully grind the cold-drawn wire;

[0023] When it is necessary to clean up the debris, pull out the pin 52. By pulling the T-shaped pull block 51, the collection box 5 can slide at the bottom of the grinding box 1. When it needs to be fixed, insert the pin 52 into the T-shaped pull block 51 and the first fixing block 11 to achieve the fixing effect, so as to collect the debris generated during the grinding process.

[0024] Obviously, those skilled in the art can make various changes and modifications to the present utility model without departing from the spirit and scope of the present utility model. Thus, if these modifications and variations of the present utility model fall within the scope of the claims of the present utility model and their equivalent technologies, the present utility model is also intended to include these modifications and variations.
