Abstract
Description
Technical Field
[0001] This application relates to the field of steel bar processing equipment technology, and in particular to a stainless steel steel bar bending device and its usage method. Background Technology
[0002] Ordinary carbon steel reinforcing bars are prone to corrosion and failure. In coastal areas and regions where de-icing salt is frequently used, chloride ions in groundwater can penetrate the concrete and corrode the reinforcing bars. Furthermore, the carbonation of concrete lowers its alkalinity, reducing its protective effect on the reinforcing bars and leading to corrosion, concrete shrinkage, and the formation of fine cracks on the concrete surface. Stainless steel reinforcing bars, on the other hand, have strong resistance to chloride ion corrosion, allowing for a reduction in the thickness of the concrete protective layer, improving the durability of the concrete structure, and lowering maintenance and repair costs.
[0003] Chinese patent CN115889624B discloses a rebar bending device. To address the issues of damage to the surfaces of the central shaft and stop shaft in existing rebar bending devices after prolonged use, which affects the bending quality, and the high production cost due to the need to reorder the entire set of components for replacement since the central shaft and stop shaft are typically accessories on the bending device, the patent employs a longitudinally movable central shaft and stop shaft. This prevents the central shaft and stop shaft from always being in contact with the rebar at the same position, reducing surface damage and protecting the central shaft and stop shaft.
[0004] While the aforementioned improvements to the existing technology can prevent the center shaft and the stop shaft from always contacting the reinforcing bar at the same position, the strength of the center shaft and the stop shaft will be affected after long-term use and surface damage. This may cause further deformation when bending the reinforcing bar. Furthermore, after repeated use, the extended parts of the center shaft and the stop shaft may become too long, which can easily affect the bending work of the operator. Summary of the Invention

[0058] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0059] First, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this application and are not intended to limit the scope of protection of this application. Those skilled in the art can make adjustments as needed to adapt to specific application scenarios.
[0060] Secondly, it should be noted that in the description of this application, the terms "upper", "lower", "left", "right", "front", "back", "inner", "outer", etc., which indicate the direction or positional relationship, are based on the direction or positional relationship shown in the accompanying drawings. This is only for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this application.
[0061] like Figure 1-5 As shown in the figure, this application provides a stainless steel rebar bending device, including a fixed platform 120, a movable platform 130, a conveying wheel assembly, a stop frame 200, and a clamping wheel assembly; the movable platform 130 is movably attached to the side of the fixed platform 120 and can rotate around the fixed platform 120; the conveying wheel assembly is installed on the upper surface of the fixed platform 120, and the conveying wheel assemblies form a clamping channel 500 for clamping the stainless steel rebar; the stop frame 200 is located on one side of the clamping channel 500 for blocking the stainless steel rebar; the clamping wheel assembly is installed on the upper surface of the movable platform 130 for clamping one end of the stainless steel rebar.
[0062] Furthermore, two second fixing blocks 140 are symmetrically arranged above the fixed platform 120. The second fixing blocks 140 are semi-circular in structure, with their flat ends facing each other. A stop frame 200 is installed at the connection between the flat end and the arc end of each second fixing block 140. A worktable 110 is arranged below the fixed platform 120, and a movable track 111 is arranged on the worktable 110. A movable table 130 is installed in the movable track 111.
[0063] Specifically, since the flat ends of the two semi-circular second fixing blocks 140 are opposite each other, and the conveyor wheel assembly is installed between the two second fixing blocks 140, the flat ends of the two second fixing blocks 140 form the clamping channel 500. When the baffles 200 are installed at the connection between the flat end and the arc end of the second fixing block 140, both ends of the stainless steel steel bar located in the clamping channel 500 can be bent, which makes it convenient for different operators to operate in different positions.
[0064] Furthermore, such as Figure 6 As shown, the retaining frame 200 includes a top plate 210, a bent plate 220, a second insert rod 230, and a limiting rod 240. The bent plate 220 is connected to one side of the top plate 210. One end of the second insert rod 230 is connected to the bottom surface of the top plate 210, and the other end of the second insert rod 230 is inserted into the insertion hole 141 opened on the upper surface of the second fixing block 140. One side of the bent plate 220 is in contact with the flat end of the second fixing block 140, and the other side of the bent plate 220 is spaced from the arc end of the second fixing block 140. The limiting rod 240 is located within the space, and one end of the limiting rod 240 is connected to the bent plate 220, while the other end of the limiting rod 240 abuts against the arc end of the second fixing block 140.
[0065] Specifically, the top plate 210 is a rhomboid or rhomboid-like plate structure. The specific structural setting is determined based on the structure at the connection between the flat end and the arc end of the second fixing block 140. When the connection between the flat end and the arc end of the second fixing block 140 is an arc surface, the top plate 210 is a rhomboid-like plate structure with two rounded corners, and the two rounded corners are diagonal.
[0066] Preferably, the top plate 210 is a rectangular plate structure with two rounded corners that are diagonally opposite each other. This structure ensures that when both sides of the curved plate 220 are in contact with the stainless steel reinforcing bars, the stainless steel reinforcing bars are bent at 90 degrees. The limiting rod 240 restricts the installation position of the stop frame 200, thereby determining the wear location on the side of the stop frame 200. This makes subsequent metalworking or cutting and reuse more convenient.
[0067] Furthermore, such as Figure 7 As shown, the conveyor wheel assembly includes two conveyor wheels 300, which are located in the mounting groove 142 opened at the flat end of the second fixed block 140. The conveyor wheel 300 includes a drive rod 310, a first intermediate sleeve 320, and a first outer sleeve 330; an elongated hole 121 is opened on the upper surface of the fixed platform 120, the drive rod 310 is movably installed in the elongated hole 121, and the first outer sleeve 330 is installed on the drive rod 310 through the first intermediate sleeve 320.
[0068] Specifically, the workbench 110 is equipped with a driving component (not shown in the figure; any component capable of driving in the prior art is compatible, such as a drive motor). The driving component is connected to the driving rod 310 for transmission. The driving component is used to rotate the driving rod 310 and to move the driving rod 310 along the direction of the elongated hole 121. When the driving rod 310 rotates, it can drive the first outer sleeve 330 to push the stainless steel bar, thereby adjusting the bending position. When the driving rod 310 moves along the direction of the elongated hole 121, it will change the width of the clamping channel 500 formed between the two first outer sleeves 330, thus accommodating stainless steel bars of different sizes and models.
[0069] Furthermore, the driving rod 310 includes a rotating rod 311, a fixed rod 312, two third fixed blocks 313, and two arc-shaped plates 314. The rotating rod 311 is movably installed in the elongated hole 121 and can rotate and move along the direction of the elongated hole 121. The fixed rod 312 is located at the top of the rotating rod 311. The two third fixed blocks 313 are respectively fixed on both sides of the fixed rod 312, and the two arc-shaped plates 314 are respectively fixed on the other two sides of the fixed rod 312. The bottom surfaces of the fixed rod 312, the third fixed blocks 313, and the arc-shaped plates 314 are coplanar.
[0070] Specifically, the first intermediate sleeve 320 has a first slot 321 in the middle, which matches the fixing block, the third fixing block 313 and the arc plate 314. The outer ring of the first intermediate sleeve 320 has a plurality of second slots 322 in a ring array, and the two ends of the second slots 322 respectively penetrate the upper surface and the lower surface of the first intermediate sleeve 320.
[0071] Specifically, the first outer sleeve 330 is arranged in a ring structure. The inner ring of the first outer sleeve 330 is arranged in a ring array with multiple second locking blocks 331. The second locking blocks 331 are used to lock into the second locking slots 322. The outer ring of the first outer sleeve 330 is provided with a first arc-shaped surface 332. Multiple third locking slots 333 are arranged in a ring array on the first arc-shaped surface 332. The two ends of the third locking slots 333 respectively penetrate the upper surface and the lower surface of the first outer sleeve 330.
[0072] Specifically, when the first intermediate sleeve 320 is fitted onto the drive rod 310, the bottom surface of the first intermediate sleeve 320 is coplanar with the bottom surfaces of the fixed rod 312, the third fixed block 313, and the arc plate 314, and the top surface of the first intermediate sleeve 320 is coplanar with the top surfaces of the fixed rod 312 and the third fixed block 313. In this embodiment, both the drive rod 310 and the first intermediate sleeve 320 are made of hard metal material, and the first outer sleeve 330 is made of hard rubber material. Furthermore, the inner ring of the first outer sleeve 330 is interference-fitted with the outer ring of the first intermediate sleeve 320.
[0073] Furthermore, such as Figure 3As shown, the movable table 130 includes a first fixing block 131, a first locking block 132, and two first insert rods 133; the first fixing block 131 is located on the upper surface of the worktable 110, the first locking block 132 is disposed on the lower surface of the first fixing block 131 and is movably locked into the movable track 111, and the two first insert rods 133 are both disposed on the upper surface of the first fixing block 131; Figure 8 As shown, the clamping wheel assembly includes two clamping wheels 400, and each clamping wheel 400 includes a second intermediate sleeve 410 and a second outer sleeve 430; the second outer sleeve 430 is rotatably mounted on the first insert rod 133 via the second intermediate sleeve 410.
[0074] Specifically, the drive unit is also used to move the movable platform 130 along the movable track 111. Among them, the two first inserts 133 on the same first fixing block 131 are positioned such that one is closer to the inner ring of the first fixing block 131 and the other is closer to the outer ring of the first fixing block 131. This misalignment allows for better thrust to be applied to the stainless steel steel bars when bending them.
[0075] Furthermore, the second intermediate sleeve 410 is arranged in a ring structure and is movably sleeved on the first insert rod 133. The outer ring of the second intermediate sleeve 410 is provided with a plurality of fifth slots 412 in a ring array. The two ends of the fifth slots 412 respectively penetrate the upper surface and the lower surface of the second intermediate sleeve 410. The second outer sleeve 430 is arranged in a ring structure. The inner ring of the second outer sleeve 430 is provided with a plurality of third blocks 431 in a ring array. The third blocks 431 are used to engage in the fifth slots 412. The outer ring of the second outer sleeve 430 is provided with a second arc-shaped surface 432. The second arc-shaped surface 432 is provided with a plurality of fourth blocks 433 in a ring array. The two ends of the fourth blocks 433 are coplanar with the outer ring of the second outer sleeve 430.
[0076] Specifically, the second intermediate sleeve 410 is made of hard metal material, the second outer sleeve 430 is made of hard rubber material, and the inner ring of the second outer sleeve 430 is interference-fitted with the outer ring of the second intermediate sleeve 410.
[0077] Furthermore, the bottom end of the second intermediate sleeve 410 is provided with a plurality of fourth slots 411 in a circular array. A ball bearing 420 is movably engaged in the fourth slot 411, and the bottom end of the ball bearing 420 is used to abut against the upper surface of the first fixing block 131.
[0078] The working principle of the stainless steel bar bending device in this embodiment is as follows:
[0079] In use, the stainless steel rebar is first placed into the clamping channel 500 formed by the conveyor wheel assembly, with the end of the rebar positioned within the wheel assembly. During bending, the movable table 130 rotates around the fixed table 120, causing the rebar to bend. The bending is achieved by the stop frame 200 on one side of the clamping channel 500. This stainless steel rebar bending device differs from existing technologies that involve replacing or extending the central shaft and stop shaft. The stop frame 200 serves merely as a protective spacer, ensuring the bending device itself is not damaged by the bending operation. This design results in lower manufacturing costs, easier replacement, and no disruption to the operator's work.
[0080] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0081] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
