Description

Technical Field

[0001] The present application relates to the technical field of steel bar processing equipment, and in particular to a stainless steel bar bending device and a method for using the same. Background Art

[0002] Ordinary carbon steel bars are prone to rust and failure. In coastal areas and areas where snow-melting salt is frequently used, chloride ions in groundwater can penetrate concrete to corrode the steel bars. Moreover, due to the carbonization of concrete, the alkalinity of concrete decreases, which weakens the protective effect of concrete on the steel bars, thus causing the steel bars to rust and shrink, and easily causing fine cracks on the concrete surface. Stainless steel bars have a strong ability to resist chloride ion corrosion, which can reduce the thickness of the concrete protective layer, improve the durability of the concrete structure, and reduce maintenance and repair costs.

[0003] A Chinese patent with authorization announcement number CN115889624B discloses a steel bar production and bending device. In order to solve the problem that after long-term use of the existing steel bar bending device, the surface of the center shaft and the iron stop shaft will be damaged, affecting the steel bar bending quality, and because the center shaft and the iron stop shaft are usually supporting products on the steel bar bending device, the complete set of products needs to be re-ordered when replaced, which results in high production costs, a longitudinally movable center shaft and iron stop shaft are used to prevent the center shaft and the iron stop shaft from always contacting the steel bar at the same position, reduce damage to the surface of the center shaft and the iron stop shaft, and protect the center shaft and the iron stop shaft.

[0004] Although the above-mentioned improvement method to the prior art can prevent the center axis and the iron stop shaft from always contacting the steel bar at the same position, the strength of the center axis and the iron stop shaft will be affected after long-term use and surface damage. Further deformation is likely to occur when the steel bar is bent. In addition, the protruding parts of the center axis and the iron stop shaft are too long after repeated use, which can easily affect the bending work of the operator. Summary of the invention

[0058] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0059] First, those skilled in the art should understand that these implementations are only used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application. Those skilled in the art can make adjustments to them as needed to adapt to specific application scenarios.

[0060] Secondly, it should be noted that in the description of the present application, terms such as "up", "down", "left", "right", "front", "back", "inside" and "outside" indicating directions or positional relationships are based on the directions or positional relationships shown in the drawings. This is merely for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present application.

[0061] like Figure 1-5 As shown, an embodiment of the present application provides a stainless steel rebar bending device, including a fixed table 120, a movable table 130, a conveying wheel group, an iron stop frame 200 and a clamping wheel group; the movable table 130 is movably attached to the side of the fixed table 120 and can rotate around the fixed table 120; the conveying wheel group is installed on the upper surface of the fixed table 120, and a clamping channel 500 is formed between the conveying wheel groups for clamping the stainless steel rebar; the iron stop frame 200 is located on one side of the clamping channel 500 for blocking the stainless steel rebar; the clamping wheel group is installed on the upper surface of the movable table 130 for clamping one end of the stainless steel rebar.

[0062] Furthermore, two second fixed blocks 140 are symmetrically arranged above the fixed table 120. The second fixed blocks 140 are arranged in a semicircular structure. The planar ends of the two second fixed blocks 140 are opposite to each other, and iron blocks 200 are installed at the connection between the planar ends and the curved ends of the second fixed blocks 140; a workbench 110 is arranged below the fixed table 120, and a movable track 111 is arranged on the workbench 110, and the movable table 130 is installed in the movable track 111.

[0063] Specifically, since the planar ends of the two semicircular second fixed blocks 140 are opposite to each other and the conveying wheel group is installed between the two second fixed blocks 140, the above-mentioned clamping channel 500 is formed between the planar ends of the two second fixed blocks 140. When the iron stop frame 200 is installed at the connection between the planar end and the curved end of the second fixed block 140, both ends of the stainless steel bars located in the clamping channel 500 can be bent, which is convenient for different operators to operate at different positions.

[0064] Furthermore, if Figure 6 As shown, the iron stop frame 200 includes a top plate 210, a bent plate 220, a second plug rod 230 and a limit rod 240; the bent plate 220 is connected to one side of the top plate 210, one end of the second plug rod 230 is connected to the bottom surface of the top plate 210, and the other end of the second plug rod 230 is inserted into the socket 141 opened on the upper surface of the second fixed block 140, one side of the bent plate 220 is in contact with the plane end of the second fixed block 140, and the other side of the bent plate 220 has a gap with the arc surface end of the second fixed block 140, the limit rod 240 is located in the gap, and one end of the limit rod 240 is connected to the bent plate 220, and the other end of the limit rod 240 is in contact with the arc surface end of the second fixed block 140.

[0065] Specifically, the top plate 210 is a rhombus-shaped or rhombus-like plate structure, and the specific structural setting is determined according to the structure of the connection between the plane end and the curved surface end of the second fixed block 140. When the connection between the plane end and the curved surface end of the second fixed block 140 is an arc-shaped surface, the top plate 210 is a rhombus-like plate structure having two rounded corners, and the two rounded corners are diagonally opposite.

[0066] Preferably, the top plate 210 is a plate-like structure similar to a rectangle, which has two rounded corners, and the two rounded corners are diagonal. This structural setting makes the stainless steel bar bend at 90 degrees when both sides of the bent plate 220 are in contact with the stainless steel bar. The setting of the limit rod 240 can limit the installation position of the iron stop frame 200, so that the wear position of the side of the iron stop frame 200 can be determined, which is more convenient whether it is processed by metal processing means or cut before use.

[0067] Furthermore, if Figure 7 As shown, the conveying wheel assembly includes two conveying wheels 300, and the conveying wheels 300 are located in the mounting groove 142 opened at the plane end of the second fixed block 140. The conveying wheel 300 includes a driving rod 310, a first intermediate sleeve 320 and a first external sleeve 330; a long hole 121 is opened on the upper surface of the fixed platform 120, and the driving rod 310 is movably installed in the long hole 121, and the first external sleeve 330 is installed on the driving rod 310 through the first intermediate sleeve 320.

[0068] Specifically, a driving member (not shown in the figure, any member capable of achieving driving in the prior art, such as a driving motor) is provided inside the workbench 110, and the driving member is connected to the driving rod 310 in a transmission manner, wherein the driving member is used to rotate the driving rod 310 and to move the driving rod 310 along the direction of the long hole 121. When the driving rod 310 rotates, it can drive the first external sleeve 330 to push the stainless steel bar to move, thereby adjusting the bending position. When the driving rod 310 moves along the direction of the long hole 121, the width of the clamping channel 500 formed between the two first external sleeves 330 will change, thereby being suitable for stainless steel bars of different sizes.

[0069] Furthermore, the driving rod 310 includes a rotating rod 311, a fixed rod 312, two third fixed blocks 313 and two arc plates 314; the rotating rod 311 is movably installed in the long hole 121, the rotating rod 311 can rotate and move along the direction of the long hole 121, the fixed rod 312 is arranged at the top end of the rotating rod 311, the two third fixed blocks 313 are respectively fixed on both sides of the fixed rod 312, the two arc plates 314 are respectively fixed on the other two sides of the fixed rod 312, and the bottom surfaces of the fixed rod 312, the third fixed blocks 313 and the arc plates 314 are coplanar.

[0070] Specifically, a first card slot 321 is opened in the middle of the first intermediate sleeve 320, and the first card slot 321 matches the fixed block, the third fixed block 313 and the arc plate 314. The outer ring of the first intermediate sleeve 320 is opened with multiple second card slots 322 in a circular array, and the two ends of the second card slots 322 pass through the upper surface and the lower surface of the first intermediate sleeve 320 respectively.

[0071] Specifically, the first external sleeve 330 is arranged in an annular structure, and the inner ring of the first external sleeve 330 is provided with a plurality of second clamping blocks 331 in an annular array, and the second clamping blocks 331 are used to be clamped in the second clamping groove 322. The outer ring of the first external sleeve 330 is provided with a first arc surface 332, and the first arc surface 332 is provided with a plurality of third clamping grooves 333 in an annular array, and the two ends of the third clamping groove 333 respectively pass through the upper surface and the lower surface of the first external sleeve 330.

[0072] Specifically, when the first intermediate sleeve 320 is sleeved on the driving 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, the driving rod 310 and the first intermediate sleeve 320 are both made of hard metal material, the first external sleeve 330 is made of hard rubber material, and the inner ring of the first external sleeve 330 is interference fit with the outer ring of the first intermediate sleeve 320.

[0073] Furthermore, if Figure 3As shown, the movable platform 130 includes a first fixed block 131, a first clamping block 132 and two first insertion rods 133; the first fixed block 131 is located on the upper surface of the workbench 110, the first clamping block 132 is arranged on the lower surface of the first fixed block 131, and is movably clamped in the movable track 111, and the two first insertion rods 133 are arranged on the upper surface of the first fixed block 131; Figure 8 As shown, the clamping wheel assembly includes two clamping wheels 400 , and the clamping wheel 400 includes a second middle sleeve 410 and a second outer sleeve 430 ; the second outer sleeve 430 is rotatably mounted on the first insertion rod 133 through the second middle sleeve 410 .

[0074] Specifically, the driving member is also used to move the movable platform 130 along the movable track 111. Among them, the two first insertion rods 133 on the same first fixed block 131, one is closer to the inner circle of the first fixed block 131, and the other is closer to the outer circle of the first fixed block 131. This staggered setting enables better thrust to be applied to the stainless steel bar when the stainless steel bar is bent.

[0075] Furthermore, the second intermediate sleeve 410 is arranged in an annular structure, and the second intermediate sleeve 410 is movably sleeved on the first plug rod 133.

[0078] The working principle of the stainless steel bar bending device of this embodiment is:

[0079] When in use, first put the stainless steel bar into the clamping channel 500 formed by the conveying wheel group, and place the end of the stainless steel bar in the clamping wheel group. When bending the stainless steel bar, the movable table 130 rotates around the fixed table 120, and the stainless steel bar will be bent during the rotation. The stainless steel bar will be blocked by the iron stop frame 200 on one side of the clamping channel 500. The stainless steel bar bending device of this embodiment is different from the prior art in which the central axis and the iron stop axis are replaced or telescopically moved. The iron stop frame 200 is only used as a spacer protective object, which can ensure that the bending device itself will not be damaged due to the bending operation. The manufacturing cost is lower and the replacement is more convenient, and it will not affect the operation of the operator.
