Description

Technical Field

[0001] This utility model belongs to the field of steel bar processing technology, and in particular relates to a circular steel bar processing device with adjustable diameter. Background Technology

[0002] Reinforcing bars are an indispensable steel material in construction engineering, mainly used to enhance the tensile strength of concrete components. Bending reinforcing bars into circles (or rings) is a very common process in reinforcing bar processing, such as for manufacturing spiral stirrups, reinforcing stirrups for pile foundations, sealing groove bars for tunnel segments, and various decorative components. Circular reinforcing bar processing equipment is one of the important pieces of equipment in reinforcing bar bending, which can greatly improve bending efficiency, especially in the production of large-diameter reinforcing bar rings.

[0003] A search revealed CN203751207U, application date 2014.04.14, which discloses a circular rebar processing device for building construction. This device effectively solves the technical problem that a mold cannot process circular rebars of different annular diameters, and that the rebars are prone to detachment during processing. The circular rebar processing device includes a circular operating platform and a positioning steel belt ring, which is mounted on the circular operating platform. It also includes a top support, a limiting groove, and a limiting pin. The wide surface of the positioning steel belt ring has at least three threaded holes evenly distributed along its circumference. The top support is connected to the threaded holes and consists of an anti-slip top end and a threaded connection end. The limiting groove has at least one limiting hole, and the limiting pin is embedded in the limiting hole. The limiting groove is mounted on the circular operating platform and located outside the positioning steel belt ring.

[0004] However, it still has the following drawbacks in practical use:

[0005] 1. Existing round steel bar processing equipment adjusts multiple positioning steel belt rings individually by thread during use. This method is cumbersome, time-consuming, labor-intensive, inefficient, wasteful of manpower, and labor-intensive.

[0006] 2. Existing circular rebar processing devices lack measures to limit the rebar ends during use, which may cause the ends to detach during rebar bending, posing a safety hazard. Therefore, we provide an adjustable-diameter circular rebar processing device to solve the above-mentioned problem. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] Example 1

[0033] Please see Figures 1 to 5This utility model is a circular rebar processing device with adjustable diameter, including a body 100 and a turntable 102 rotatably mounted on its upper surface. A synchronization disc 103 is mounted on the upper surface of the turntable 102. A second sliding groove 103b is formed at one end of the synchronization disc 103. A limiting post 105 is slidably installed inside the second sliding groove 103b. A top post 105a is fixed at the center of the top of the limiting post 105. A mounting frame 106 is mounted at the center of the upper surface of the synchronization disc 103. The top of the mounting frame 106... A ring plate 106a is fixedly provided, and a top frame 106b is fixedly provided at the top of the inner wall of the ring plate 106a. An adjusting component 200 is provided inside the mounting frame 106, and a moving component 300 is provided at the top of the top frame 106b. The adjusting component 200 includes a motor 201 installed inside the mounting frame 106 and a drive cone wheel 202 installed on the output shaft of the motor 201. The moving component 300 includes a fixed seat 301 fixed on the upper surface of the top frame 106b and a sliding sleeve 302 installed inside the fixed seat 301.

[0034] Specifically, wheels 101 are installed around the bottom of the machine body 100; the upper surface of the turntable 102 is provided with evenly spaced first grooves 102a along its outer circumference, and a column 104 is slidably installed inside the first grooves 102a; the upper surface of the synchronous disc 103 is provided with evenly spaced strip holes 103a along its outer circumference, and the strip holes 103a correspond one-to-one with the first grooves 102a; driven cone wheels 203 are evenly meshed around the top of the driving cone wheel 202 along the outer circumference of the ring plate 106a, and a first screw 204 is fixed at the center of the outer wall of the driven cone wheel 203; the first screw 204... The other end passes through the bearing on the ring plate 106a and is connected to the limiting plate 204a. A moving block 205 is spirally sleeved on the outer wall of the first screw 204. The bottom of the moving block 205 is connected to the top of the corresponding column 104. A sliding cylinder 303 is slidably installed inside the sliding sleeve 302. A hanging ring 303a is fixed in the middle of the outer wall of the sliding cylinder 303. The hanging ring 303a is hung on the outer wall of the top column 105a. A handwheel 304 is provided on the outer side of the sliding sleeve 302. A second screw 305 is fixed in the center of the inner wall of the handwheel 304. The other end of the second screw 305 passes through the bearing on the sliding sleeve 302 and is spirally engaged with the threaded groove on the sliding cylinder 303.

[0035] Furthermore, the machine body 100 is equipped with a drive device for low-speed driving of the turntable 102 and the synchronous disc 103 to rotate, thereby achieving bending processing of the reinforcing bars. The bottom of the limiting column 105 is slidably installed inside the second slide groove 103b, serving as a limiting and assisting sliding function. The outer end of the second slide groove 103b is open. The bottom of the column 104 is radially T-shaped and slidably inserted into the first slide groove 102a, serving as a limiting and assisting sliding function. Multiple strip holes 103a are provided, corresponding to multiple first slide grooves 102a. The column 104 passes through the strip holes 103a. Multiple driven cone wheels 203 are provided and mesh with the driving cone wheel 202 (the driving cone wheel 202 meshes with multiple...). The axes of the driven conical wheels 203 intersect perpendicularly, serving as a transmission mechanism to achieve synchronous rotation of multiple first screws 204. The external threads on the outer wall of the first screw 204 are helically engaged with the threaded holes on the moving block 205, so the rotation of the first screw 204 can adjust the position of the moving block 205. The bottom of the moving block 205 is connected to the column 104, so the rotation of the first screw 204 can prevent the moving block 205 from rotating synchronously. The slide cylinder 303 is slidably sleeved inside the slide sleeve 302, serving as a limit and assisting sliding mechanism. The external threads on the outer wall of the second screw 305 are helically engaged with the threaded grooves on the slide cylinder 303, so the rotation of the second screw 305 can drive the slide cylinder 303 to move along the inner wall of the slide sleeve 302.

[0036] The operation process of this embodiment is as follows: During use, external steel bar conveying equipment continuously conveys bent steel bars. Before bending the steel bars, the bending diameter of the steel bars needs to be adjusted according to construction requirements. First, the motor 201 is started. The rotation of the output shaft of the motor 201 can drive the active cone wheel 202 to rotate. The active cone wheel 202 meshes with multiple driven cone wheels 203 around it. Therefore, when the active cone wheel 202 rotates, it can drive multiple driven cone wheels 203 to rotate synchronously. The rotation of the driven cone wheels 203 will drive the corresponding first screw 204 to rotate. The external thread on the outer wall of the first screw 204 is screwed into the threaded hole on the moving block 205. Therefore, the rotation of the first screw 204 will drive the moving block 205 to move. Since the bottom of the moving block 205 is fixed to the top of the column 104, and the bottom end of the column 104 is slidably installed inside the first slide groove 102a, the movement of the moving block 205 will drive the column 104 to move along the first slide groove 102a. The motor 201 can synchronously and quickly adjust the position of multiple columns 104 by rotating forward and reverse to adjust the bending diameter of the steel bar. It is easy to operate and has high work efficiency. After the position of multiple columns 104 is adjusted, the position of the limiting column 105 needs to be adjusted synchronously. At this time, the handwheel 304 is rotated. The rotation of the handwheel 304 will drive the second screw 305 to rotate. The external thread on the outer wall of the second screw 305 is helically engaged with the thread groove on the slide cylinder 303. Therefore, when the second screw 305 rotates, it can drive the slide cylinder 303 to move along the inner wall of the slide sleeve 302. The hanging ring 303a and the top column 105a are used to adjust the position of the limiting column 105. After the end of the steel bar is fixed, the drive device inside the machine body 100 is started. The turntable 102 and the synchronous disc 103 are rotated at low speed, so that the steel bar is rotated and bent under the limiting action of multiple columns 104 and limiting column 105 to complete the processing of round steel bars.

[0037] Example 2

[0038] Please see Figure 5 and Figure 6 Based on Embodiment 1, unlike the first embodiment, a protective component 400 is provided. The protective component 400 includes a sleeve plate 401 rotatably sleeved on the outer wall of the top column 105a, and a rotating shaft 402 rotatably installed at one end of the bottom of the sleeve plate 401. This solves the problem that the existing circular steel bar processing device lacks measures to limit the end of the steel bar during use, so the end of the steel bar may fall off during the bending process, which poses a safety hazard.

[0039] Specifically, a protective cylinder 403 is fixed at the bottom of the rotating shaft 402, and a rubber pad is adhered to the inner wall of the protective cylinder 403.

[0040] Furthermore, the sleeve 401 is rotatably sleeved on the outer wall of the top column 105a. The sleeve 401 is located below the hanging ring 303a. The position and opening direction of the protective cylinder 403 can be adjusted through the sleeve 401 and the rotating shaft 402. The rubber pad on the inner wall of the protective cylinder 403 can protect the reinforcing bar and the protective cylinder 403 and prevent slippage. The protective cylinder 403 can limit the end of the reinforcing bar.

[0041] The operation process of this embodiment is as follows: After the positions of multiple columns 104 and limiting columns 105 are adjusted synchronously, since the sleeve plate 401 is rotated and sleeved on the outer wall of the top column 105a, and the protective cylinder 403 is rotated and installed at the bottom of the sleeve plate 401 through the rotating shaft 402, the opening position of the protective cylinder 403 can be rotated and adjusted as needed. Then, the end of the steel bar is inserted into the protective cylinder 403. During the rotation and bending of the steel bar, the end of the steel bar can be limited to prevent the end of the steel bar from falling off, which is highly safe.
