Description

Technical Field

[0001] The utility model relates to the technical field of steel bar processing devices, in particular to a steel bar processing device. Background Art

[0002] A rebar processing device is a piece of equipment or equipment used to process rebar. Typically, it is used to process and treat rebar so that it meets specific standards and requirements. These devices can include a variety of machines, tools and equipment used to bend, cut, shape and process rebar for use in the construction, engineering and manufacturing fields.

[0003] In the prior art, a construction steel bar processing device disclosed in the patent with the announcement number CN112571247B mainly grinds and removes rust on the steel bar by reciprocating left and right movements of a first grinding block and a second grinding block and rotating the steel bar.

[0004] It is known from the technology in the related field that for the steel bar processing devices, most of them process the surface of the steel bar by grinding at a fixed angle. When the convex and concave points on the steel bar are not easy to grind, the processing of the steel bar is not comprehensive enough and the processing effect is poor. Utility Model Content

[0005] The purpose of the utility model is to provide a steel bar processing device in order to solve the above problems.

[0006] The utility model achieves the above-mentioned purpose through the following technical solutions:

[0007] A steel bar processing device comprises a sandblasting processing mechanism, a conveying unit and a power unit for assisting in comprehensive processing of the steel bars.

[0008] Sandblasting mechanism: vertical plates are installed at both ends, a transfer block is installed at the front end of the front vertical plate, a positioning mechanism is installed on the upper side of the front end of the front vertical plate, and a discharging mechanism is installed at the rear end of the rear vertical plate; when the steel bars to be processed are put into the hole in the middle of the front vertical plate, the position of the steel bars can be limited by the positioning mechanism, and when the processing of the steel bars is completed, the end of the remaining steel bars can be brought out through the operation of the discharging mechanism.

[0009] Conveying unit: comprising two wheel tubes rotatably connected to the front and rear of one side of the transfer block, the ends of the wheel tubes away from the transfer block are both equipped with rubber wheels, the inside of the rubber wheels is hollow, and the circumferences of the two rubber wheels are respectively equidistantly provided with different numbers of ribs, the ribs are spiral-shaped, an F-shaped groove is provided inside the transfer block, an F-shaped plate is slidably connected inside the F-shaped groove, an F-shaped air release groove is provided on the side of the F-shaped plate close to the wheel tube, and an elastic component and an air supply component are respectively provided inside the transfer block; when the air supply component is connected to an external air source After the connection, the positive pressure gas enters one of the wheel tubes through the F-shaped groove, and then enters the corresponding rubber wheel, causing it to expand, and the corresponding ribs on the circumference of the rubber wheel contact the lower side of the steel bar; when the power unit is working, the position of the F-shaped plate can be changed to achieve alternating inflation of the two rubber wheels, and the gas in the unventilated rubber wheel can be discharged again through the wheel tube and the air release groove. Because the two rubber wheels are of different sizes and have different numbers of ribs on their circumferences, the distances they move with the steel bar are different, and the steel bar ribs gradually contact the steel bar with a certain force difference, and the rotation angles of the steel bar are also different.

[0010] Power unit: It includes a driving shaft that is rotatably connected to the middle of the transfer block, a lever is installed on the driving shaft, a rod guide hole is opened on the other side of the transfer block, and a plate rod is installed on the other side of the F-type plate, and the plate rod is located in the rod guide hole. When the driving shaft rotates counterclockwise, the lever can contact the plate rod with each rotation, thereby providing a power basis for the position change of the F-type plate. The lever does not contact the plate rod, and the F-type plate can be reset by relying on the elastic component.

[0011] Furthermore, the elastic component includes a power groove, the power groove is communicated with the lower side of the rear end of the F-shaped groove, one end of the elastic member is connected to the lower side of the rear end of the F-shaped plate, and the other end of the elastic member is connected to the inner rear end of the power groove. When the driving shaft rotates with the shifting rod, the shifting rod first contacts the belt plate rod and moves with it, and after it is in place, the shifting rod no longer contacts the belt plate rod, and at this time, the elastic force of the elastic member can be used to reset the F-shaped plate.

[0012] Furthermore, the air supply assembly includes an air supply groove, which is communicated with the F-shaped groove, and a gas pipe joint is installed at the front end of the other side of the transfer block. When the gas pipe joint is connected to the external air source, the external positive pressure gas continuously enters the air supply groove, and then enters the F-shaped groove. By changing the position of the F-shaped plate, the gas can alternately enter the two wheel tubes, so that the two rubber wheels are alternately inflated and deflated.

[0013] Furthermore, the power unit also includes a main gear installed at one end of the driving shaft extending out of the transfer block, and the two wheel tubes are both equipped with slave gears, and the main gear is respectively meshed and connected with the two slave gears, and a motor with a mounting seat is installed at the front end of the front vertical plate, and the output shaft of the motor is connected to the other end of the driving shaft. When the motor is working, it drives the driving shaft to rotate counterclockwise, and through the meshing of the main gear with the two slave gears, the two wheel tubes drive the corresponding rubber wheels to rotate clockwise.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0015] 1. The utility model uses two rubber wheels rotating in the same direction to inflate alternately. The two rubber wheels are different in size and have different numbers of ribs on their respective circumferences. Therefore, when the steel bars are moved separately, the steel bars move different distances. The sprayed sand can contact the convex and concave points on the steel bars from multiple different angles, thereby achieving comprehensive treatment of the steel bars.

[0016] 2. In the utility model, when the rubber wheel rotates, the ribs on it gradually contact the steel bars, and there is a certain force difference on both sides of the steel bars, which can make the steel bars rotate at a certain angle. The number, length and protruding height of the ribs are different, so the rotation angle of the steel bars is different when they move. The sprayed sand can better process the surface of the steel bars from different angles, which is conducive to comprehensive processing of the steel bars and has better effects.

[0030] The utility model is further described below in conjunction with the accompanying drawings:

[0031] Example

[0032] like Figure 1-Figure 8 As shown, a steel bar processing device includes a sandblasting processing mechanism 1, a conveying unit and a power unit for assisting in comprehensive processing of the steel bars.

[0033] Sandblasting mechanism 1: vertical plates 2 are installed at both ends, a transfer block 3 is installed at the front end of the front vertical plate 2, a positioning mechanism 21 is installed on the upper side of the front end of the front vertical plate 2, and a discharge mechanism 22 is installed at the rear end of the rear vertical plate 2; Figure 1 and Figure 2 As shown, when the steel bars to be processed are placed from the hole in the middle of the front side vertical plate 2, the position of the steel bars can be limited by the positioning mechanism 21. When the processing of the steel bars is completed, the remaining ends of the processed steel bars can be brought out through the operation of the discharging mechanism 22, thereby completing the processing of the steel bars.

[0034] The conveying unit comprises two wheel tubes 4 rotatably connected to the front and rear of one side of the transfer block 3. A rubber wheel 5 is installed at one end of the wheel tube 4 away from the transfer block 3. The inside of the rubber wheel 5 is hollow. The circumference of the two rubber wheels 5 is equidistantly provided with different numbers of ribs 6. The ribs 6 are spiral-shaped. An F-shaped groove 7 is provided inside the transfer block 3. An F-shaped plate 9 is slidably connected inside the F-shaped groove 7. An F-shaped air release groove 11 is provided on the side of the F-shaped plate 9 close to the wheel tube 4. An elastic component and an air supply component are provided inside the transfer block 3; Figure 3 , Figure 4 and Figure 5 As shown, when the air supply assembly is connected to an external air source, the positive pressure gas enters one of the wheel tubes 4 through the F-shaped groove 7, and then enters the corresponding rubber wheel 5 to expand it. The ribs 6 on the circumference of the rubber wheel 5 contact the lower side of the steel bar. When the wheel tube 4 rotates, the steel bar can be moved by friction with the circumference of the rubber wheel 5 to process it; Figure 6 and Figure 7 As shown, when the power unit is working, the position of the F-type plate 9 can be changed to realize the alternating inflation of the two rubber wheels 5. The gas in the unventilated rubber wheel 5 can be discharged again through the wheel tube 4 and the air release groove 11. Because the two rubber wheels 5 are of different sizes and the number of ribs 6 on their respective circumferences is different, the distances moved with the steel bars are different, and the steel bar ribs 6 gradually contact the steel bars with a certain force difference. The rotation angles of the steel bars are also different, which can make the ejected sand contact the convex and concave points on the steel bars from multiple different angles, so as to realize comprehensive treatment of the steel bars, and the treatment of the steel bars is more comprehensive and the effect is better.

[0035] The power unit includes a driving shaft 12 rotatably connected to the middle of the transfer block 3, a lever 13 is installed on the driving shaft 12, a rod guide hole 14 is opened on the other side of the transfer block 3, and a plate rod 15 is installed on the other side of the F-type plate 9. The plate rod 15 is located in the rod guide hole 14. Figure 3 and Figure 4 As shown, when the driving shaft 12 rotates counterclockwise, each rotation can make the lever 13 contact with the plate rod 15, thereby providing a power basis for the position change of the F-type plate 9. The lever 13 does not contact the plate rod 15, and the F-type plate 9 can be reset by relying on the elastic component, thereby ensuring the stability of the alternating inflation and deflation of the two rubber wheels 5.

[0036] The elastic component includes a power groove 8, which is connected to the lower rear end of the F-shaped groove 7. The lower rear end of the F-shaped plate 9 is connected to one end of an elastic member 10, and the other end of the elastic member 10 is connected to the inner rear end of the power groove 8. Figure 3 , Figure 4 and Figure 7 As shown, when the driving shaft 12 rotates with the lever 13, the lever 13 first contacts the plate rod 15 and moves it. After it is in place, the lever 13 no longer contacts the plate rod 15. At this time, the elastic force of the elastic member 10 can be used to reset the F-type plate 9, which is convenient for the subsequent position switching of the F-type plate 9 and ensures the stability of the alternating inflation and deflation of the two rubber wheels 5.

[0037] The air supply assembly includes an air supply groove 19, which is connected to the F-shaped groove 7. A gas pipe joint 20 is installed at the front end of the other side of the transfer block 3. Figure 4 and Figure 5 As shown, when the air pipe joint 20 is connected to the external air source, the external positive pressure gas continuously enters the air supply groove 19, and then enters the F-shaped groove 7. By changing the position of the F-shaped plate 9, the gas can alternately enter the two wheel tubes 4, so that the two rubber wheels 5 are alternately inflated and deflated, so that the steel bars can be rotated to different degrees while being transported, and the surface of the steel bars can be sandblasted at more angles, the treatment is more comprehensive, and the effect is better.

[0038] The power unit also includes a main gear 16 installed at one end of the driving shaft 12 extending out of the transfer block 3, and two wheel tubes 4 are each installed with a slave gear 17, and the main gear 16 is respectively meshed and connected with the two slave gears 17, and a motor 18 with a mounting seat is installed at the front end of the front side vertical plate 2, and the output shaft of the motor 18 is connected to the other end of the driving shaft 12. Figure 2 and Figure 3 As shown, when the motor 18 is working, it drives the driving shaft 12 to rotate counterclockwise, and through the main gear 16 meshing with the two slave gears 17 respectively, the two wheel tubes 4 drive the corresponding rubber wheels 5 to rotate clockwise, and when they come into contact with the steel bars, the steel bars can be transported into the equipment for processing.

[0039] Working principle: When in use, Figure 1-Figure 8 As shown, the steel bar to be processed is put into the hole in the middle of the front side vertical plate 2, and the position of the steel bar is limited by the positioning mechanism 21. The lower end of the steel bar contacts a rubber wheel 5 that rises therein, and the motor 18 works, driving the driving shaft 12 to rotate counterclockwise. The main gear 16 is respectively engaged with the two slave gears 17, and the two wheel tubes 4 are driven by the corresponding rubber wheels 5 to rotate clockwise, so that the steel bar can be transported into the equipment for processing. When the processing of the steel bar is completed, the end of the remaining steel bar to be processed can be taken out through the operation of the discharging mechanism 22, thereby completing the processing of the steel bar;

[0040] like Figure 4 and Figure 5 As shown, the air pipe joint 20 is connected to the external air source, and the external positive pressure gas continuously enters the air supply groove 19 and then enters the F-shaped groove 7. Figure 3 and Figure 4 As shown, when the driving shaft 12 rotates counterclockwise, each rotation can make the lever 13 contact with the plate rod 15, so that the position of the F-type plate 9 moves from the front side position to the rear side position. When the lever 13 is not in contact with the plate rod 15, the F-type plate 9 can be restored to the front side position by relying on the elastic component, so that the two rubber wheels 5 are alternately inflated and deflated;

[0041] like Figure 3 , Figure 4 and Figure 5 As shown, the spiral ribs 6 on the circumference of the inflated rubber wheel 5 are in contact with the lower side of the steel bar. When the wheel tube 4 rotates, the steel bar can be moved and processed by the friction with the circumference of the rubber wheel 5. The two rubber wheels 5 are different in size and have different numbers of ribs 6 on their respective circumferences. Therefore, when the steel bars are moved respectively, the distances moved by the steel bars are different. At the same time, the ribs 6 gradually contact the steel bars with a certain force difference, and the angles of rotation of the steel bars are also different, which makes it convenient for the ejected sand to contact the convex and concave points on the steel bars from multiple different angles, thereby achieving comprehensive processing of the steel bars, making the processing of the steel bars more comprehensive and effective.

[0042] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
