[0002] In fields such as construction, steel bars are a widely used building material. In order to meet the requirements of different projects, cold rolling processing of steel bars is often required to improve the strength of steel bars and improve their surface quality.

[0003] During the cold rolling process, there is a large frictional force between the steel bar and the rolling mill roll. This not only easily causes wear of the roll, increases the equipment maintenance cost, but also may shorten the service life of the roll, thereby affecting the continuity of production. To reduce friction, lubricating powder is usually applied during the cold rolling of steel bars, but the existing devices lack effective control in the lubricating powder application link. For example, it is difficult to achieve quantitative application, which may lead to waste or insufficient application of lubricating powder, affecting the cold rolling effect; a small amount of lubricating powder is easily spilled during the transmission and cold rolling of steel bars, resulting in waste.

A powder storage box 5 is fixed on the top wall of the box body 2. Lubricating powder is stored in the powder storage box 5. The function of the lubricating powder is to reduce the friction between the steel bar and the cold rolling roller 164, protect the rolling roller and the steel bar, and also effectively reduce the heat generation of the steel bar. A plurality of powder outlet pipes 6 are communicated with the bottom of the powder storage box 5. The lubricating powder in the powder storage box 5 is discharged through the powder outlet pipes 6. A vertical rod 7 is fixed on the bottom wall of the powder storage box 5, and a powder coating seat 8 is fixed on the top of the vertical rod 7. The steel bar 3 passes through the powder coating seat 8 and slides inside it. There is a certain gap between the steel bar 3 and the powder coating seat 8, which is convenient for the lubricating powder to be evenly distributed in the powder coating seat 8. A plurality of powder inlet ports 9 are formed on the top of the powder coating seat 8. The powder inlet ports 9 are aligned with the powder outlet pipes 6 in the vertical direction, which is convenient for the lubricating powder to accurately fall into the powder inlet ports 9 after being discharged from the powder outlet pipes 6. A quantitative powder discharging mechanism 10 for intermittent quantitative powder discharging is arranged inside the powder storage box 5; The quantitative powder discharging mechanism 10 includes a horizontal plate 101 arranged inside the powder storage box 5. A plurality of side plates 102 are fixed on one side of the horizontal plate 101. A powder discharging cone 103 is fixed on the bottom of the side plate 102. The powder discharging cone 103 is provided to facilitate stabbing into the powder outlet pipe 6 during the downward movement of the powder discharging cone 103, and accelerate the rapid discharge of the residual lubricating powder in the powder outlet pipe 6.

A connecting column 1046 is fixed on one side of the connecting plate 1045. The connecting column 1046 is provided to drive the Z-shaped rod 10410 to rotate, so that the Z-shaped rod 10410 disengages from the L-shaped limiting block 10414.

[0021] On one side of the L-shaped plate 1048, there is a folded rod 10411 fixed. At one end of the folded rod 10411, there is a square plate 10412 fixed. Between one side of the square plate 10412 and one side of the Z-shaped rod 10410, there is a first spring 10413 fixed. The setting of the first spring 10413 is used to reset the Z-shaped rod 10410 after rotation. On one side of the mounting seat 1047, there is an L-shaped limit block 10414 fixed. On one side of the top end of the Z-shaped rod 10410, there is a protrusion, and the protrusion is hung on the convex edge of the L-shaped limit block 10414. After the protrusion is stuck on the convex edge, the Z-shaped rod 10410 cannot move downward, so that the L-shaped plate 1048 can be jacked up for a period of time. By using this period of time, the lubricating powder can be intermittently dropped, so as to realize the operation of quantitative powder discharging. Cooperating with the stable transmission speed of the steel bar 3, the steel bar 3 can be evenly coated with the lubricating powder stably for a long time. The arc surface of the turntable 1042 and the side surface of the convex block 1044 are both in rolling contact with the side surface of the roller 1049.

The top end of the vertical rod 10415 extends into the powder storage box 5, and the vertical rod 10415 slides vertically in the powder storage box 5. The top end of the vertical rod 10415 is fixed to the bottom of the cross plate 101. A second spring 10416 is sleeved on the outer surface of the vertical rod 10415. The setting of the second spring 10416 is used to quickly reset the L-shaped plate 1048 downward. The top end of the second spring 10416 is fixed to the bottom of the powder storage box 5, and the bottom end of the second spring 10416 is fixed to the top of the L-shaped plate 1048.

[0022] Through the setting of the quantitative powder discharging mechanism 10, the lubricating powder is intermittently and quantitatively discharged into the powder coating seat 8, and then by using the transmission of the steel bar 3, the lubricating powder is evenly coated on the steel bar 3, effectively solving the problem that it is difficult to quantitatively coat the lubricating powder on the steel bar 3 before cold rolling, avoiding the waste or insufficient coating of the lubricating powder, enabling the steel bar 3 to be fully coated with the lubricating powder before cold rolling, thereby reducing the friction with the cold rolling roll 164 and improving the cold rolling effect.

[0023] Embodiment 2, on the basis of Embodiment 1, refer to Figure 1 、 Figure 2 、 Figure 7 、 Figure 8As shown, a collection and circulation unit 11 is arranged inside the box body 2. The collection and circulation unit 11 is used to collect the lubricating powder scattered during the cold rolling of the steel bars 3. The collection and circulation unit 11 includes a collection box 111 fixed on one side of the powder coating seat 8. The bottom wall of the collection box 111 is inclined. This setting allows the lubricating powder to slide along the inclined plane to one side, facilitating collection. One side of the powder storage box 5 is communicated with an elbow pipe 112. The bottom end of the elbow pipe 112 is communicated with a powder suction head 113. A material suction pump 114 is installed on the elbow pipe 112. The material suction pump 114 is controlled by an external switch and is electrically connected to an external power supply. After the material suction pump 114 is started, the powder suction head 113 generates suction force, quickly sucking the lubricating powder that has slid to one side into the powder storage box 5 for the operation of quantitative powder discharging again.

[0024] A powder inlet pipe 14 is communicated with the top of the box body 2. The bottom end of the powder inlet pipe 14 extends into the interior of the powder storage box 5. The top of the powder inlet pipe 14 is communicated with a hopper 15. The external lubricating powder is poured into the hopper 15 and enters the powder storage box 5 through the powder inlet pipe 14 for storage.

[0025] A cold rolling mechanism 16 is arranged on the top of the bottom plate 1. The cold rolling mechanism 16 includes two vertical frames 161 fixed on the top of the bottom plate 1. Fixed blocks 162 are fixed inside both of the two vertical frames 161. Sliders 163 are slidably connected inside both of the two vertical frames 161. Cold rolling rollers 164 are rotatably connected between the two sliders 163 and the fixed blocks 162. The setting of the two sliders 163 facilitates adjusting the distance between the cold rolling rollers 164, thereby realizing the rapid adjustment of the cold rolling size of the steel bars. The tops of both of the two vertical frames 161 are fixed with cylinders 165. The two cylinders 165 are controlled by the same external switch and are electrically connected to the external power supply. The cylinders 165 drive the sliders 163 to slide vertically.

[0026] Example 3, on the basis of Example 2, see Figure 2 and Figure 6 As shown, a knocking box component 12 for knocking the collection box 111 is arranged inside the box body 2. The knocking box component 12 is used to knock the collection box 111 to make the lubricating powder on its bottom wall slide to one side along the inclined plane. The knocking box component 12 includes two vertical plates 121 fixed on the bottom wall of the box body 2. A seesaw 122 is rotatably connected between the opposite sides of the two vertical plates 121 through a pin shaft. The top of the connecting column 1046 contacts and presses against the bottom of the seesaw 122. A third spring 123 is fixed on the bottom wall of the box body 2. The setting of the third spring 123 is used to make the seesaw 122 store energy, so that the seesaw 122 quickly bounces upward to complete the knocking action. The bottom of the seesaw 122 contacts and presses against the top end of the third spring 123. One side of the seesaw 122 is fixed with an extension plate 124. The top of the extension plate 124 is fixed with a fixed rod 125. The top end of the fixed rod 125 is fixed with a knocking ball 126. The knocking ball 126 contacts the bottom of the collection box 111. After the knocking ball 126 knocks the collection box 111, the speed of the lubricating powder sliding down along the inclined plane is accelerated.

[0027] Through the setting of the knocking box component 12, after the lubricating powder falls into the collecting box 111, the collecting box 111 is intermittently and rapidly knocked by the knocking ball 126, so that the lubricating powder in the collecting box 111 can slide to one side along the inclined plane of the bottom wall of the collecting box 111, thereby facilitating the powder suction head 113 to quickly collect the clean lubricating powder, realizing the rapid and centralized collection of the lubricating powder in the collecting box 111 and improving the powder suction efficiency.

[0028] A powder knocking unit 13 for knocking the steel bar 3 is arranged on the extension plate 124 and on one side of the box body 2. The powder knocking unit 13 is used to knock the steel bar 3 so that the redundant lubricating powder on the steel bar 3 falls into the collecting box 111 for collection. The powder knocking unit 13 includes a mounting rod 131 fixed on the top of the extension plate 124. A connecting ball 132 is fixed at the top end of the mounting rod 131. One side of the box body 2 is rotatably connected with a rotating plate 134 through a rotating rod 133. The connecting ball 132 contacts the bottom of the rotating plate 134. A plurality of spherical balls 135 are fixed at the bottom of the rotating plate 134. After the spherical balls 135 knock the steel bar 3, the redundant lubricating powder on the steel bar 3 can be bounced off to avoid waste.

[0029] Through the setting of the powder knocking unit 13, after the steel bar 3 is coated with lubricating powder, the connecting ball 132 is used to intermittently knock the steel bar 3, and then the redundant lubricating powder on the steel bar 3 is knocked off and falls into the collecting box 111 for collection. Then, the material suction pump 114 is started to re-inhale the lubricating powder into the powder storage box 5 for the operation of quantitative blanking again for secondary utilization, preventing the waste of lubricating powder and reducing the coating cost.

[0030] Meanwhile, the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0031] During operation, the lubricating powder is poured into the hopper 15, and the lubricating powder flows into the powder storage box 5, and then is discharged into the powder inlet through the powder outlet pipe 6 and flows into the powder coating seat 8, and the steel bar 3 passes through the box body 2 and the powder coating seat 8, and comes out through the through hole 4, and the motor 1043 is started, so that the motor 1043 drives the turntable 1042 to rotate, and then the turntable 1042 drives the protrusion 1044 to rotate, and then the protrusion 1044 contacts the roller 1049 and drives the roller 1049, the L-shaped plate 1048, the vertical rod 10415, the horizontal plate 101, and the powder discharge cone 103 to push up, At the same time, the L-shaped plate 1048 drives the Z-shaped rod 10410 to be lifted up, and cooperates with the spring 10413 to clamp the Z-shaped rod 10410 on the L-shaped limit block 10414, so that the powder discharge cone 103 slides out of the powder discharge pipe 6. At this time, the lubricating powder enters the powder discharge pipe 6. As the turntable 1042 rotates, the connecting column 1046 is driven to rotate synchronously. When the connecting column 1046 contacts the Z-shaped rod 10410, it drives the Z-shaped rod 10410 to rotate. At this time, the Z-shaped rod 10410 is separated from the L-shaped limit block 10414, and cooperates with the elastic force of the spring 2 10416 to drive the L-shaped The plate 1048 moves downward to reset, thereby driving the powder discharge cone 103 to be inserted into the powder discharge pipe 6. The powder discharge cone 103 discharges all the lubricating powder remaining in the powder discharge pipe 6 into the powder coating seat 8. As the steel bar 3 is transmitted from right to left, the lubricating powder is evenly applied to the steel bar 3. During the upward rotation of the connecting column 1046, the rocker 122 is driven to rotate and press the spring three 123 to store force. When the connecting column 1046 is separated from the rocker 122, the stored force spring three 123 drives the rocker 122, the extension plate 124, the knocking ball 126, the installation rod 131, and the connecting ball 13 2 tilts upward, and during the upward movement of the connecting ball 132, the rotating plate 134 is turned over, and then the multiple balls 135 are driven to knock the steel bar 3, so that the excess lubricating powder on the steel bar 3 falls into the collecting box 111. The knocking ball 126 quickly knocks the collecting box 111 when tilting upward, and the lubricating powder in the collecting box 111 slides down along the inclined surface, and then the suction pump 114 is started to suck the lubricating powder into the powder storage box 5. After the steel bar 3 is fully coated with the lubricating powder, it is cold-rolled by two cold-rolling rollers 164 to be formed. The lubricating powder effectively reduces the friction between the steel bar 3 and the rollers.

[0032] The above embodiments of the invention are described in detail, but the contents are only preferred embodiments of the invention and cannot be considered to limit the scope of the invention. All equivalent changes and improvements made within the scope of the invention should still fall within the scope of the invention.
