Description
Technical Field
[0001] The utility model belongs to the technical field of steel bar processing and relates to steel bar sleeve extrusion equipment. Background Art
[0002] Rebar sleeve extrusion equipment is a special equipment used to extrude and deform special steel sleeves so that the steel bars and the steel sleeves are interlocked and connected into one. It is often used to extend the length of the steel bars during the construction process. However, there are still some shortcomings in the existing rebar sleeve extrusion equipment, such as:
[0003] A steel sleeve extruder disclosed in the publication number CN208195527U on December 7, 2018, includes an extrusion box, an ascending button is provided on the extrusion box, a descending button is provided on one side of the ascending button, a feed button is provided on one side of the descending button, a discharging button is provided on one side of the feed button, and an adhesive button is provided on one side of the discharging button. A sleeve inlet is provided at the bottom of the ascending button, a steel bar inlet is provided on one side of the extrusion box, an extrusion cavity is provided in the extrusion box, an extrusion rod is provided in the extrusion cavity, an upper extrusion head is provided at the bottom of the extrusion rod, and a lower extrusion head is provided at the bottom of the upper extrusion head.
[0004] The above document uses a semicircular upper extrusion head and a lower extrusion head to cooperate with each other to ensure the extrusion effect. The adhesive can effectively remove the gap between the steel bar and the sleeve after extrusion, so that the connection effect is better.
[0005] However, the above document can only extrude steel bars at one end of the sleeve, and during processing, the two ends of the sleeve need to be connected to the steel bars. The extrusion efficiency of the above equipment needs to be improved. At the same time, when the steel bars are inserted into the sleeve, due to the gravity of the steel bars, the inserted exposed steel bars will tilt downward. During extrusion, it is easy to cause the steel bars and the sleeve to be skewed, thereby affecting the neatness of the extrusion of the steel bars and the sleeve. Therefore, we propose a steel bar sleeve extrusion equipment to solve the above problems. Utility Model Content
[0006] The purpose of the utility model is to provide a steel sleeve extrusion device, which solves the problem in the prior art that only one end of the sleeve can be extruded, and the gravity of the steel bar during extrusion easily causes the steel bar and the sleeve to become skewed, affecting the neatness of the extrusion of the steel bar and the sleeve.
[0007] The technical solution adopted by the utility model is that it includes a square placement seat, a square through groove is opened in the middle of the side surface of the placement seat, and extrusion components are respectively provided on the inner walls opposite to the through groove. The outer wall of the placement seat is connected to the pressure component, and two protrusions are fixedly connected to the side surfaces of the placement seat perpendicular to the through groove.

The midpoint of the transition section between the two sections of the thread on the bidirectional screw rod is located in the same horizontal plane as the center of the through groove. The outer sides of the thread sections of the bidirectional screw rod that rotate in different directions are respectively connected to support plates. One side of each support plate is in contact with the surface of the placement seat, and one end of the bidirectional screw rod is fixedly connected to a power component.

[0010] The extrusion assembly includes two extrusion cavities respectively opened on the inner walls opposite to the through slot. The two extrusion cavities are fixedly connected to the inner walls away from the through slot with extrusion springs respectively. The other end of each extrusion spring is fixedly connected to an extrusion block.
[0011] The side surfaces of the extrusion blocks fit tightly against the inner wall of the extrusion cavity. The sides of the two extrusion blocks corresponding to the through slots are both concave arc surfaces, and anti-sliding blocks are fixedly connected to the arc surfaces.
[0012] The pressure assembly includes several air guide tubes connected to the outside of the placement seat, and the air guide tubes are respectively connected to the two extrusion chambers.

[0016] The outer wall of the placement seat corresponding to the closed end of the through slot is fixedly connected to a push box, and a hydraulic rod is fixedly connected inside the push box. The movable end of the hydraulic rod passes through the placement seat and extends into the through slot, and the movable end of the hydraulic rod is fixedly connected to a push plate.

[0025] The present invention will be described in detail below with reference to the accompanying drawings and specific implementation methods.
[0026] Example 1:
[0027] like Figure 1 and Figure 4As shown, it includes a square placement seat 1, a square through groove 2 is opened in the middle of the side of the placement seat 1, which is used to accommodate the steel bars and sleeves to be processed, and extrusion components 3 are respectively provided on the two opposite inner walls of the through groove 2. The outer wall of the placement seat 1 is connected to the pressure component 4, and the side surfaces of the placement seat 1 perpendicular to the through groove 2 are fixed with two protrusions 5, and the two protrusions 5 are arranged in a direction perpendicular to the top of the placement seat 1, and a bidirectional screw rod 6 passes through the two protrusions 5 on the same side of the placement seat 1. The midpoint of the transition section between the two sections of the thread on the bidirectional screw rod 6 is located in the same horizontal plane as the center of the through groove 2. The bidirectional screw rod 6 rotates to different thread sections and is respectively connected to the outside of support plates 7. One side of each support plate 7 is fitted with the surface of the placement seat 1, and the placement seat 1 is used as a positioning track for the support plate 7, so that the support plate 7 can move up and down smoothly. One end of the bidirectional screw rod 6 is fixedly connected to a power component 17. When the bidirectional screw 6 rotates, the support plates 7 on the same side are driven closer to each other through the different rotation directions of the threads, which plays a role in fixing the steel bars. This prevents the ends of the steel bars from sinking when inserted into the sleeve due to gravity during the placement of the steel bars, causing the connection between the steel bars and the sleeve to be skewed, affecting the connection effect of the steel bars and the sleeve.
[0028] Example 2
[0029] Based on Example 1:
[0030] like Figure 2 As shown, the power assembly 17 includes a pulley 8 fixedly connected to the top of each bidirectional screw 6. The multiple pulleys 8 are connected by a transmission belt 9. A servo motor 10 is fixed to the top of the placement base 1, and the output end of the servo motor 10 is fixedly connected to one of the pulleys 8. The transmission belt 9 causes all the pulleys 8 to rotate synchronously, so that the support plates 7 on both sides of the placement base 1 move to the designated position at the same time, fixing the steel bars and preventing the steel bars from skewing due to the different positions of the support plates 7.
[0031] The two protrusions 5 on the same side of the placement seat 1 are respectively located on both sides of the through groove 2, and the two support plates 7 are located between the two protrusions 5. The two support plates 7 on the same bidirectional screw rod 6 are fixedly connected with a buffer pad 11 on the opposite surfaces. The buffer pad 11 is relatively soft in texture and can adapt to the uneven surface of the steel bar through its own deformation, thereby avoiding loosening caused by the uneven surface of the steel bar.
[0032] Example 3:
[0033] Based on Example 1:
[0034] like Figure 3 and Figure 4As shown, the extrusion assembly 3 includes two extrusion chambers 31 respectively opened on the opposite inner walls of the through slot 2. The two extrusion chambers 31 are fixedly connected to the inner walls away from the through slot 2 with extrusion springs 32 respectively. The other end of each extrusion spring 32 is fixedly connected to an extrusion block 33. The extrusion spring 32 is used to reset the extrusion block 33 so that the equipment can operate in a cycle.
[0035] The side surfaces of the extrusion blocks 33 fit tightly against the inner wall of the extrusion chamber 31, maintaining the air tightness in the extrusion chamber 31 and preventing the extrusion force from decreasing due to air leakage, so that the pressure assembly 4 can stably apply pressure for extrusion. The two extrusion blocks 33 and the sides corresponding to the through grooves 2 are both concave arc surfaces, and an anti-sliding block 34 is fixedly connected to the arc surface. The arc surface is convenient for accommodating the steel sleeve, and the anti-sliding block 34 on the arc surface is used to prevent the steel sleeve from sliding during the extrusion process. At the same time, the anti-sliding block 34 can also increase the pressure during extrusion by reducing the contact area, further improving the deformation degree of the steel sleeve, and making the connection more stable.
[0036] Example 4:
[0037] Based on Example 1:
[0038] like Figure 1 and Figure 3 As shown, the pressure assembly 4 includes several air guide tubes 41 connected to the outside of the placement seat 1, and the air guide tubes 41 are respectively connected to the two extrusion chambers 31, and the other ends of the several air guide tubes 41 are connected to the air collecting frame 42, and one side of the air collecting frame 42 is connected to the air pump 43. The gas is sent into the extrusion chamber 31 through the air pump 43, and the extrusion block 33 is driven by pressure to move for extrusion.
[0039] The connection port between the air guide tube 41 and the extrusion chamber 31 is located inside the extrusion chamber 31 on a side away from the extrusion block 33 , so as to prevent the extrusion block 33 from blocking the connection port and causing a decrease in the pressure increase rate in the extrusion chamber 31 .
[0040] An operation panel 12 is fixedly connected to one side of the air pump 43. The operation panel 12 is electrically connected to the servo motor 10 and the air pump 43 respectively. The operation of the equipment is controlled by the operation panel 12. A pressure gauge 13 is fixedly connected to the top of the air collecting frame 42 for judging the operating status of the equipment.
[0041] Embodiment 5:
[0042] Based on Example 1:
[0043] like Figure 3As shown, the outer wall of the placement seat 1 corresponding to the closed end of the through slot 2 is fixedly connected with a pushing box 14, and a hydraulic rod 15 is fixedly connected inside the pushing box 14. The movable end of the hydraulic rod 15 passes through the placement seat 1 and extends into the through slot 2. The movable end of the hydraulic rod 15 is fixedly connected with a pushing plate 16. The hydraulic rod 15 pushes the pushing plate 16 to push the extruded steel sleeve out of the through slot 2 for the next extrusion.
[0044] Working methods:
[0045] When in use, first place the steel sleeve on the extrusion block 33, then start the air pump 43 through the operation panel 12, and deliver gas to the extrusion chamber 31 through the air guide pipe 41, thereby increasing the pressure in the extrusion chamber 31 and causing the two extrusion blocks 33 to move toward the center of the placement seat 1 until the two extrusion blocks 33 come into contact with the steel sleeve, and then stop pressurizing;
[0046] After that, steel bars are inserted into both ends of the steel bar sleeve respectively, and then the servo motor 10 is controlled to rotate through the operation panel 12. The servo motor 10 drives all the bidirectional screws 6 to rotate simultaneously through the transmission belt 9 and the pulley 8. Under the action of the threads on the surface of the bidirectional screws 6, the support plate 7 moves toward the center of the placement seat 1 to fix the steel bars;
[0047] Finally, the air pump 43 is restarted through the operation panel 12, driving the extrusion block 33 to extrude the steel bar sleeve. After the extrusion is completed, the air in the extrusion chamber is evacuated by the air pump 43. Under the action of the external atmospheric pressure and the extrusion spring 32, the extrusion block 33 is reset. At the same time, the servo motor 10 rotates in the opposite direction, moving the support plate 7 away from the steel bar. Then, the hydraulic rod 15 pushes the push plate 16 out, pushing the extruded steel bar sleeve out of the through slot 2, completing the extrusion process.
