Description

Technical Field

[0001] This utility model relates to the field of bar production technology, specifically to an automatic centering and feeding mechanism for a high-speed bar production line. Background Technology

[0002] Bar stock is an indispensable material in civil engineering projects such as houses, bridges, and roads. With the continuous expansion of urbanization, large-scale investment in infrastructure, and the booming development of the real estate industry, the market demand for bar stock is becoming increasingly strong, and the delivery conditions are becoming increasingly stringent.

[0003] The feeding structure of traditional bar production lines has the problem of insufficient centering accuracy: this causes the bars to collide and scrape when entering the rotating hub guide tube, generating noise and wear, and even causing steel jamming and steel piling accidents, which seriously affect the production efficiency and quality of bars. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] An automatic centering and feeding mechanism for a high-speed bar production line includes a centering mechanism and a guiding mechanism. The centering mechanism includes a steel plate, a cylindrical frame fixed to the top of the steel plate, a rotating arm rotatably mounted on the top of the cylindrical frame, and a cross laser fixed to the outer end of the rotating arm. The guiding mechanism includes two rings rotatably sleeved at both ends of the cylindrical frame, four long rectangular blocks fixed to the outer side of the rings, a rod fixed to the inner side of the long rectangular blocks, a short rectangular block slidably sleeved to the outer side of the rod and fixed to the end face of the cylindrical frame, two arc-shaped toothed plates respectively installed at the bottom of the two rings, two straight toothed plates respectively meshing with the bottom of the two arc-shaped toothed plates, a connecting rod fixed between the two straight toothed plates, and an electric push rod fixed between the steel plate and the connecting rod.

[0007] By adopting the above technical solution, the rotating arm is flipped so that the cross laser is aligned with the center of the rotating hub, thereby accurately locating and positioning the cylinder frame. Then, the steel plate is mechanically welded to the bearing rotating hub. The bar is then passed through the rectangular opening. Here, the movable end of the electric push rod retracts, and the connecting rod affects the rotation of the ring body through the straight tooth plate and the arc tooth plate. Then, the long rectangular block carries the rod to rotate. Because the rod is limited by the short rectangular block, the rectangular opening between the multiple rods will continuously shrink. This process continues until the multiple rods clamp the bar. Then, the external instrument pushes the tail end of the bar, which can make the bar accurately enter the interior of the rotating hub, ensuring the production efficiency and quality of the bar.

[0008] In a preferred embodiment, the present invention can be further configured such that the cross laser is horizontally positioned and coaxial with the barrel frame laterally.

[0009] In a preferred embodiment, the present invention can be further configured such that four rods located on one side of the tube frame are staggered, and a rectangular opening is formed between the four rods.

[0010] In a preferred embodiment, the present invention can be further configured such that the rod is made of stainless steel and the outer surface of the rod is polished.

[0011] In a preferred embodiment, the present invention can be further configured such that the bottom of the straight toothed plate is attached to the top of the steel plate.

[0012] In a preferred embodiment, the present invention can be further configured such that the electric push rod is disposed between two straight tooth plates, and the electric push rod is electrically connected to an external PLC.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] In this invention, the rotating arm is flipped so that the cross laser is aligned with the center of the rotating hub, thereby accurately locating and positioning the cylinder frame. Then, the steel plate is mechanically welded to the rotating hub. The rod is then passed through the rectangular opening. Here, the movable end of the electric push rod retracts, and the connecting rod affects the rotation of the ring body through the straight tooth plate and the arc tooth plate. Then, the long rectangular block carries the rod body to rotate. Because the rod body is limited by the short rectangular block, the rectangular opening between the multiple rod bodies will continuously shrink. This process continues until the multiple rod bodies clamp the rod body. Then, the external instrument pushes the tail end of the rod body, which can make the rod body accurately enter the interior of the rotating hub, ensuring the production efficiency and quality of the rod body.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0024] It should be understood that these descriptions are merely exemplary and are not intended to limit the scope of this invention.

[0025] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, an automatic centering and feeding mechanism for a high-speed bar production line.

[0026] Example 1:

[0027] Combination Figure 1-5 As shown, the present invention provides an automatic centering and feeding mechanism for a high-speed bar production line, including a centering mechanism 100 and a guiding mechanism 200. The centering mechanism 100 includes a steel plate 110, a cylinder frame 120 fixed to the top of the steel plate 110, a rotating arm 130 rotatably mounted on the top of the cylinder frame 120, and a cross laser 140 fixed to the outer end of the rotating arm 130.

[0028] The guide mechanism 200 includes two rings 210 rotatably sleeved at both ends of the cylindrical frame 120, four long rectangular blocks 220 fixed to the outside of the rings 210, a rod 230 fixed to the inside of the long rectangular blocks 220, a short rectangular block 240 slidably sleeved to the outside of the rod 230 and fixed to the end face of the cylindrical frame 120, two arc-shaped toothed plates 250 respectively installed at the bottom of the two rings 210, two straight toothed plates 260 respectively meshing with the bottom of the two arc-shaped toothed plates 250, a connecting rod 270 fixed between the two straight toothed plates 260, and an electric push rod 280 fixed between the steel plate 110 and the connecting rod 270.

[0029] Furthermore, the cross laser 140 is horizontally positioned and coaxial with the barrel frame 120 laterally. Using the cross laser 140, the barrel frame 120 can be aligned with the center of the rotating hub, providing conditions for precise feeding of the bar stock.

[0030] Furthermore, four rods 230 located on one side of the tube frame 120 are staggered, and a rectangular opening is formed between the four rods 230. The rectangular opening provides a condition for limiting rods of any diameter.

[0031] Furthermore, the bottom of the straight toothed plate 260 is attached to the top of the steel plate 110. This structural design improves the stability of the straight toothed plate 260 when it slides.

[0032] Example 2:

[0033] Combination Figure 1 , 2 4 and Figure 5 As shown, based on Embodiment 1, the rod 230 is made of stainless steel and the outer surface of the rod 230 is polished. The use of stainless steel ensures that the rod 230 can firmly clamp the rod, and the polishing process ensures that it will not scratch the rod.

[0034] Example 3:

[0035] Combination Figure 1-5 As shown, in the above embodiment, the electric push rod 280 is disposed between two straight tooth plates 260. The electric push rod 280 is electrically connected to an external PLC. Using an external PLC can improve the intelligence of this device and enhance user comfort.

[0036] The working principle and usage process of this utility model are as follows: When this device is put into actual use, the rotating arm 130 is flipped so that the cross laser 140 is aligned with the center of the rotating hub, thereby locating and positioning the position of the cylinder frame 120. Then, the steel plate 110 is mechanically welded to the bearing rotating hub by welding. Then, the rod is passed through the rectangular opening. Here, the movable end of the electric push rod 280 retracts, and the connecting rod 270 affects the rotation of the ring body 210 through the straight tooth plate 260 and the arc tooth plate 250. Then, the long rectangular block 220 rotates the rod body 230. Since the rod body 230 is limited by the short rectangular block 240, the rectangular opening between the multiple rod bodies 230 will continuously shrink. This process continues until the multiple rod bodies 230 clamp the rod body. Then, the external instrument pushes the tail end of the rod body, so that the rod body can accurately enter the interior of the rotating hub.

[0037] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
