Description

Technical Field

[0001] The invention belongs to the field of rebar rolling production, and in particular relates to a device for quickly collecting mid-rolling samples during the rebar rolling process. Background Art

[0002] During the rolling process of rebar, the control of the material shape of the entire line is crucial. Its adjustment process directly affects whether the next rolling pass is smooth and whether the quality of the finished product meets the national standard requirements. During the rolling process, affected by the wear of the groove surface, the size of the steel material will increase accordingly, which will lead to changes in the material shape. In the actual production process, each frame and each pass has its corresponding process control parameters. At this time, it is necessary to adjust the roll gap to control the material shape. In general, the measurement of material shape lies in two aspects, online material clamping and steel head measurement. Because the rolling speed in the rough rolling area is slower, the rough rolling area is generally suitable for material clamping. The rolling speed in the medium rolling area is faster, and the measurement of material clamping is bound to have certain safety hazards. Therefore, the medium rolling area is generally only suitable for steel head sampling measurement.

[0003] During the rolling process, the incoming materials from the intermediate rolling mill will be cut off at the head and tail by the 2# flying shear. After the steel head is cut off, it will fall into the scrap steel bucket under the platform through the flying shear pit. The operator will take it out from the scrap steel bucket and measure it. This will increase the labor intensity of the personnel and the time for material shape adjustment. More importantly, it will create certain safety hazards for personnel. Summary of the invention

[0020] The present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] The invention discloses a device for quickly collecting rolling samples during the rolling process of threaded steel bars. Figure 1 and Figure 2 As shown, it includes a protection plate 1, a collecting bucket 6, and a rotating rod 7.

[0022] The protective plate 1 is U-shaped and is vertically arranged. The protective plate 1 consists of a left ear plate 2, a vertical plate 3 and a right ear plate 4 which are connected in sequence. The opening of the protective plate 1 is arranged toward the shearing machine 13. The lower end of the protective plate 1 is fixed on the ground close to the shearing machine 13. An operating port 5 is provided on the vertical plate 3 of the protective plate 1. The operating port 5 is used to observe the rolling condition and the condition of the shearing machine 13.

[0023] The collecting bucket 6 is a shell with an opening at the top. The collecting bucket 6 is located in the U-shaped opening of the protective plate 1. The rotating rod 7 is located in the U-shaped opening of the protective plate 1. One end of the rotating rod 7 is fixedly connected to one side of the collecting bucket 6, and the other end of the rotating rod 7 is movably connected to the inner side of the vertical plate 3. The rotating rod 7 is used to drive the collecting bucket 6 to rotate by rotating, so that the collecting bucket 6 is located below the shearing machine 13 and then collects the steel heads cut off by the shearing machine 13.

[0024] The two ends of the rotating rod 7 are respectively a fixed end 8 and a rotating end 9. The fixed end 8 is fixedly connected to the collecting bucket 6, and the rotating end 9 is fixedly connected to a fixed plate 10. The fixed plate 10 is horizontally arranged, and a toggle hole 11 is vertically penetrated on the fixed plate 10. A plurality of force-bearing teeth are fixedly connected around the inner wall of the toggle hole 11. The toggle hole 11 is used for the power rod 12 to extend vertically. The middle part of the power rod 12 swells outward to form a boss, and a plurality of toggle teeth are fixedly connected around the boss. The toggle teeth are used to extend into the groove between two adjacent force-bearing teeth, and then by rotating the power rod 12, the force-bearing teeth and the toggle teeth cooperate with each other to rotate the rotating rod 7, and then the collecting bucket 6 is rotated, so that the collecting bucket 6 is located below the shearing machine 13 and collects the steel heads cut off by the shearing machine 13.

[0025] The lower end of the power rod 12 is connected to the inner bearing of the protection plate 1, and the axis of the bearing coincides with the axis of the power rod 12, so that the power rod 12 can drive the rotating rod 7 to rotate during the rotation process, so that the collecting bucket 6 is located below the shearing machine 13 to collect the steel heads cut off by the shearing machine 13.

[0026] The upper end of the power rod 12 expands outward to form a rotating table, which is used to manually rotate the power rod 12. By setting the rotating table, it is convenient for personnel to operate the power rod 12 through the rotating table to rotate the rotating rod 7, making the present invention simple to operate and easier to use.

[0027] The rotating end 9 of the rotating rod 7 is arranged to pass through the operating port 5. By setting the rotating end 9 of the rotating rod 7 to pass through the operating port 5, it is convenient for personnel to operate the power rod 12 outside the protective plate 1, avoiding personnel entering the inside of the protective plate 1 and causing injuries.

[0028] The present invention also includes a discharge rod, and a through hole is opened along the direction of the rotating rod 7, and the through hole is used to accommodate the discharge rod. The axis of the discharge rod coincides with that of the rotating rod 7, and the two ends of the discharge rod are respectively an inner end and an outer end. The inner end of the discharge rod is fixedly connected to the collecting bucket 6, and the outer end of the discharge rod is fixedly connected to a fixing block. A fixing groove is opened on the end surface of the rotating end 9 of the rotating rod 7, and the fixing groove is used for the fixing block to extend into, so that the discharge rod is fixed by the fixing block to prevent the discharge rod from rotating, thereby ensuring that the opening of the collecting bucket 6 is upward, and the discharge rod is used to make the collecting bucket 6 rotate by rotating, so that the steel heads in the collecting bucket 6 can be unloaded by rotating after being full.

[0029] The power rod 12 consists of a fixed rod and a transmission rod, the fixed rod is at the bottom, the transmission rod is at the top, the fixed rod and the transmission rod are detachably connected, the fixed rod is connected to the inner bearing of the protection plate 1, and the transmission rod is located in the toggle hole 11. When unloading is required, the fixed rod and the transmission rod are separated to facilitate unloading.

[0030] By configuring the power rod 12 to consist of a fixed rod and a transmission rod, the operating difficulty of the present invention can be reduced. Because the rotating rod 7 needs to rotate in the horizontal direction when collecting steel heads so that the collecting bucket 6 is located below the shearing machine 13 and then collects the steel heads cut by the shearing machine 13, and after the collecting bucket 6 is full, it needs to rotate vertically to pour out the steel heads in the collecting bucket 6, that is, to unload the steel heads. Therefore, if the fixed rod and the transmission rod are not separated, the rotating rod 7 cannot rotate vertically and cannot be unloaded. After the fixed rod and the transmission rod are separated, when unloading the steel heads, the fixed rod and the transmission rod are separated to facilitate the vertical rotation of the rotating rod 7 for unloading.

[0031] During the rolling process of rebar, the control of the material shape of the entire line is crucial. Its adjustment process directly affects whether the next rolling pass is smooth and whether the quality of the finished product meets the national standard requirements. During the rolling process, affected by the wear of the groove surface, the size of the steel material will increase accordingly, which will lead to changes in the material shape. In the actual production process, each frame and each pass has its corresponding process control parameters. At this time, it is necessary to adjust the roll gap to control the material shape. In general, the measurement of material shape lies in two aspects, online material clamping and steel head measurement. Because the rolling speed in the rough rolling area is slower, the rough rolling area is generally suitable for material clamping. The rolling speed in the medium rolling area is faster, and the measurement of material clamping is bound to have certain safety hazards. Therefore, the medium rolling area is generally only suitable for steel head sampling measurement.

[0032] During the rolling process, the incoming materials from the intermediate rolling mill will be cut off at the head and tail by the 2# flying shear 13. After the steel head is cut off, it will fall into the scrap steel bucket under the platform through the flying shear pit. The operator will take it out from the scrap steel bucket and measure it. This will increase the labor intensity of the personnel and the material shape adjustment time. More importantly, it will cause certain safety hazards to the personnel.

[0033] By setting up the device of the present invention, the purpose of rapid sampling and rapid measurement can be achieved during normal production; because rapid measurement is possible, the accuracy and effectiveness of the measured data are improved, providing guidance for online material type and process control; sampling personnel are no longer required to step into the scrap steel bucket under the platform to take samples, and the labor intensity of personnel and the work safety environment are significantly improved.

[0034] The present invention no longer requires sampling personnel to walk to the scrap steel bucket under the platform to take samples, thereby reducing labor intensity and potential safety hazards; rapid sampling and rapid measurement can ultimately lead to rapid adjustments to ensure smooth production; the material shape adjustment time is shortened, and production continuity is no longer affected by material shape changes. According to the calculation that the material shape can be controlled 6-9 times a day, 2-3 pieces of finishing scrap steel can be eliminated every day, the hourly steel passing rate can be increased by 10-15 pieces, and the monthly efficiency can be increased by about 300,000 yuan.

[0035] Before the device was put into use, personnel had to take samples of incoming materials from the scrap bucket under the platform and then measure them. The roll gap size was adjusted according to the measured data. Each sampling measurement took 10-20 minutes to complete. Since the production process requires sampling once an hour, it takes 2-3 hours a day to complete this work, which ultimately leads to high labor intensity.

[0036] The present invention is convenient for quick material taking and quick adjustment of rolling material shape. In the prior art, the incoming material from the intermediate rolling mill will pass through the 2# flying shear head and then fall into the scrap steel bucket under the platform. The measurement personnel need to take it out from the scrap steel bucket and then measure it. This will cause several problems. First, because the online rolling is head-to-tail rolling, when the personnel take samples from the scrap steel head, the lower steel head or steel tail will fall off from its upper part, which will cause safety hazards to the personnel's sampling operation; second, each time sampling is taken, the sampling personnel need to walk to the platform and then take samples, which increases the labor intensity of the personnel; third, after taking the hot steel from the scrap steel bucket, the sampling personnel need to walk to the platform. Affected by thermal expansion and contraction, the measured size of the intermediate rolling sample does not match the actual size that needs to be adjusted, and there is no change pattern, which ultimately affects the online material shape control.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
