Description

Technical Field

[0001] The invention relates to the technical field of steel bar processing, and more specifically, to an energy-saving steel bar bending processing device for building construction. Background Art

[0002] In the process of building construction, steel bars are needed for support so that the building has sufficient strength. However, buildings are not all straight structures. Some buildings are built with curvature due to terrain restrictions or design requirements. The bending angle control device for steel bar processing equipment is a device used to control the bending angle of steel bars during the processing process, such as a steel bar bending machine. The function of the steel bar bending machine is to set and control different parameters to make the steel bar reach a predetermined angle during the bending process. The use of this device can improve the efficiency and accuracy of steel bar processing, ensure that the bent steel bars meet the design requirements, and at the same time, it also reduces the errors and labor intensity of manual operations and improves work safety.

[0003] Since most of the existing methods of bending steel bars use bending machines to bend vertical steel bars, most of them can only bend steel bars with fixed curvatures and cannot change the curvature during bending. This requires multiple bending machines to perform the bending process, which increases the processing cost. In addition, the steel bars are prone to falling off when subjected to stress during processing, and the safety is low.

DETAILED DESCRIPTION

[0030] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments.

[0033] Embodiment 1 further describes an energy-saving steel bar bending processing device for construction proposed by the present invention, including a processing equipment body 100, a workbench 101 is fixedly connected to the upper end surface of the processing equipment body 100, a motor 102 is fixedly connected inside the processing equipment body 100, a connecting plate 103 is fixedly connected to one end of the output end of the motor 102 that passes through the workbench 101, a locking pin 104 is fixedly connected to the connecting plate 103, a diameter reducing mechanism 200 is provided on the upper end surface of the connecting plate 103, a protective mechanism 300 is provided on the upper end surface of the workbench 101, the diameter reducing mechanism 200 and the protective mechanism 300 cooperate, and also include an adjustment mechanism 400;

[0034] The existing processing equipment is a special equipment for bending the straightened and cut steel bars into the required size and shape, mainly through a connecting disk 103 rotating on a vertical axis, and the center pin and the locking pin are installed on the connecting disk 103. At this time, by placing the steel bar between the center pin and the locking pin 104, the connecting disk 103 bends the steel bar when it rotates, so as to achieve the effect of bending the steel bar. The device uses a diameter reducing mechanism 200 and a protective mechanism 300 to change the bending curvature of the steel bar, and the offset member 302 and the protective member 303 cooperate to protect the workbench 101, thereby preventing the steel bar from popping out and injuring the surrounding personnel, thereby further improving the safety performance of the device;

[0035] The diameter reducing mechanism 200 includes a support member 201 disposed on the connection disk 103, a rotating member 202 is disposed in the support member 201, a movable member 203 is matched in the rotating member 202, the support member 201 limits the movable member 203, the protection mechanism 300 includes a linkage member 301 disposed on the connection disk 103, a deflection member 302 is disposed in the linkage member 301, a protection member 303 is disposed on the upper end surface of the workbench 101, and the deflection member 302 and the protection member 303 cooperate to protect the workbench 101;

[0036] Since conventional equipment can only bend steel bars with a fixed curvature and cannot change the curvature during bending, the present invention provides a reducing assembly on the connecting plate 103 to change the radius of the intermediate shaft portion. Thus, when the motor 102 drives the connecting plate 103 to rotate, the curvature of the steel bar during bending is changed due to the continuous change in the radius of the intermediate shaft portion. In addition, in the present device, the offset member 302 and the protective member 303 cooperate to protect the workbench 101. When the steel bar is bent during force processing, it is easy to slide due to the contact fixation. After sliding, it can contact the protective member 303. The protective member 303 can prevent the steel bar from popping out and injuring the surrounding personnel. At the same time, the protective plate 303e in the protective member 303 is made of spring metal material, which can effectively buffer the impact and prevent the protective plate 303e from being damaged or subjected to a large impact, thereby effectively reducing the use cost.

[0037] The adjustment mechanism 400 includes a positioning member 401 disposed on the connection plate 103, an auxiliary member 402 is disposed inside the positioning member 401, and an adjustment member 403 is also disposed inside the positioning member 401. The auxiliary member 402 cooperates with the positioning member 401. The present invention increases or decreases the reserved bending angle, so that the bending angle is corrected after the steel bar is bent, thereby providing a slightly larger target bending angle when the steel bar is bent, so that the steel bar can reach the desired angle after rebounding;

[0038] Working principle: The present invention arranges a reducing component on the connecting disk 103 to change the radius of the middle shaft portion, so that when the motor 102 drives the connecting disk 103 to rotate, the radius of the middle shaft portion changes continuously, thereby changing the bending curvature of the steel bar when it is bent. When the steel bar in the present invention falls off, it contacts the protective member 303, and the protective member 303 can prevent the steel bar from popping out and injuring the surrounding personnel. At the same time, the protective plate 303e in the protective member 303 is made of spring metal material, which can effectively buffer the impact. The present invention increases or decreases the reserved bending angle through the adjustment mechanism 400, so that the bending angle is corrected after the steel bar is bent, thereby providing a slightly larger target bending angle when the steel bar is bent, so that the steel bar can reach the desired angle after rebounding.

[0039] Embodiment 2

[0040] The following technical features are added on the basis of the first embodiment: the support member 201 includes a support ring 201a fixedly connected to the connecting plate 103, an installation space 201b is formed between the support ring 201a and the connecting plate 103, a mounting plate 201c is integrally formed inside the support ring 201a, a second motor 201d is mounted on the upper end surface of the mounting plate 201c by bolts, and a rotor shaft of the second motor 201d passes through one end of the mounting plate 201c and is fixedly connected to a rotating rod 201e, Figures 1 to 5 It can be seen that the support ring 201a is a ring-shaped hollow structure, the mounting plate 201c in the middle of the support ring 201a is a long strip on both sides and a circular structure in the middle, and the middle of the mounting plate 201c is detachably mounted with a second motor 201d, and the output shaft of the second motor 201d is fixedly connected with a rotating rod 201e, so that the rotating rod 201e can be driven to rotate by the second motor 201d;

[0041] The rotating member 202 includes a circular plate 202a fixedly connected to the outer wall of the rotating rod 201e, the outer wall of the circular plate 202a is circumferentially provided with an arc groove 202b, the arc groove 202b is composed of an initial portion 202c, a diameter-reducing portion 202d and a terminal portion 202e, and a limit rod 202f is correspondingly slidably connected in the arc groove 202b. The movable member 203 includes an opening 203a circumferentially arranged on the supporting ring 201a, and a movable rod 203b is correspondingly arranged on the upper end surface of the limit rod 202f, and the movable rod 203b correspondingly penetrates the opening 203a, and one end of the movable rod 203b is fixedly connected to a pressing plate 203c;

[0042] Depend on Figures 1 to 6 It can be seen that the bottom end of the rotating rod 201e is fixedly connected to the circular plate 202a, and there is no contact between the rotating rod 201e and the workbench 101, so the rotating rod 201e drives the circular plate 202a to rotate, and the upper end surface of the circular plate 202a is circumferentially provided with three groups of arc grooves 202b, and the arc groove 202b is composed of an initial part 202c, a diameter-reducing part 202d and a terminal part 202e, and the arc groove 202b is slidably connected to the upper part of the limit rod 202f. The movable rod 203b of the limiting rod 202f is correspondingly penetrated through the opening 203a, so the movable rod 203b can only move in the horizontal direction in the opening 203a. Through the different parts of the limiting rod 202f at the initial part 202c, the diameter-reducing part 202d and the terminal part 202e, the limiting rod 202f is subjected to the extrusion force from the arc groove 202b, thereby driving the movable rod 203b to move;

[0043] When the limiting rod 202f is at the initial portion 202c, the extrusion plate 203c on the movable rod 203b is at the minimum radius. As the limiting rod 202f slides in the diameter-changing portion 202d and the terminal portion 202e in sequence, the radius is gradually increased. In this way, when the motor 102 drives the connecting plate 103 to rotate, the radius of the intermediate shaft portion is continuously changed, thereby changing the bending curvature of the steel bar when it is bent.

[0044] The linkage member 301 includes a gear 1 301a fixedly connected to the bottom end of the connection plate 103, a driving rod 301b is rotatably connected to the upper end surface of the workbench 101 through a bearing, a gear 2 301c is keyed to the outer wall of the driving rod 301b, the gear 1 301a is meshed with the gear 2 301c, and the offset member 302 includes an offset block 302a fixedly connected to the outer wall of the driving rod 301b, and extrusion surfaces 302b are formed on both sides of the offset block 302a;

[0045] In order to prevent the steel bars from popping out and injuring people around, the present invention further improves the prior art. Figures 1 to 6It can be seen that the bottom end of the connecting plate 103 is fixedly connected with the gear 1 301a, and the side of the gear 1 301a is meshedly connected with the gear 2 301c. Therefore, when the connecting plate 103 drives the gear 1 301a to rotate, the gear 2 301c on the side thereof is driven to rotate synchronously. The gear 2 301c rotates and drives the driving rod 301b to operate. At this time, the driving rod 301b drives the offset block 302a to rotate, and the offset block 302a is a cam structure. In this way, when the offset block 302a rotates, it gives the protective plate 303e a corresponding extrusion force.

[0046] The protective member 303 is fixedly connected to the vertical plate 303a on the upper end surface of the workbench 101, and the vertical plate 303a is integrally formed with an auxiliary plate 303b in the horizontal direction. A mounting groove 303c is provided in the auxiliary plate 303b, and limiting grooves 303d are provided on both sides of the mounting groove 303c. Protective plates 303e are slidably connected in the limiting grooves 303d on both sides. Multiple groups of telescopic rods 303f are symmetrically fixedly connected in the mounting groove 303c, and a compression spring 303g is sleeved on the outer wall of the telescopic rod 303f. The compression spring 303g is a carbon spring with high strength and is convenient for daily work. One end of the compression spring 303g is fixedly connected to the mounting groove 303c, and the other end of the compression spring 303g is fixedly connected to the protective plate 303e. The offset block 302a is correspondingly against the outer wall of the protective plate 303e.

[0047] Depend on Figures 1 to 6 It can be seen that the vertical plate 303a and the auxiliary plate 303b form an L-shaped structure, and a rectangular installation groove 303c is provided in the auxiliary plate 303b, and the limiting grooves 303d on both sides of the installation groove 303c are T-shaped structures, and the auxiliary plate 303b is slidably connected in the installation groove 303c, and the two sides of the auxiliary plate 303b are T-shaped structures that match the installation groove 303c, so as to ensure the stability of the auxiliary plate 303b when moving. The auxiliary plate 303b is connected to the inner wall of the installation groove 303c through multiple groups of telescopic rods 303f and compression springs 303g. When the driving rod 301b drives the offset block 302a to rotate, the offset block 302a gives the protective plate 303e a corresponding extrusion force, thereby driving the protective plate 303e to slide in the installation groove 303c, so as to prevent the steel bar from popping out after being stressed and injuring the surrounding personnel;

[0048] Working principle: It can be known from Example 1 that when using this device, first place the steel bar between the extrusion plate 203c and the locking pin 104, start the motor 102 through the external controller, and the motor 102 rotates while driving the connecting plate 103 to rotate. When the connecting plate 103 rotates, the steel bar is bent through the extrusion plate 203c and the locking pin 104. When it is necessary to adapt to different bending curvatures of steel bars, the motor 201d can be used to drive the rotating rod 201e to rotate, and the rotating rod 201e rotates while driving the circular plate 202a to rotate. When the circular plate 202a rotates, the limiting rod 202f is correspondingly slidably connected in the arc groove 202b, and the limiting rod 202f is subjected to the extrusion force from the arc groove 202b, driving the movable rod 203b to move in the opening 203a. In this way, by changing the position of the extrusion plate 203c on the movable rod 203b, the effect of changing the bending curvature of the steel bar is achieved.

[0049] When in use, when the connecting disk 103 rotates, the gear 1 301a is driven to rotate, and the gear 1 301a is meshed with the gear 2 301c, thereby driving the gear 2 301c on its side to rotate synchronously. When the gear 2 301c rotates, the driving rod 301b is driven to operate. At this time, the driving rod 301b drives the offset block 302a to rotate, and the offset block 302a is a cam structure. When the offset block 302a rotates, it gives a corresponding extrusion force to the protective plate 303e, and the compression spring 303g on the telescopic rod 303f is deformed. At this time, the protective plate 303e extends outward, and the maximum curvature of the steel bar bending is the maximum distance the protective plate 303e moves. In this way, the steel bar is prevented from popping out after being stressed and injuring the surrounding personnel. When the connecting disk 103 rotates, the extrusion force of the offset block 302a on the protective plate 303e disappears. At this time, the force of the compression spring 303g is compressed again to drive the protective plate 303e to reset.

[0050] Embodiment 3

[0051] The following technical features are added on the basis of the second embodiment: the positioning member 401 includes a positioning block 401a arranged on the upper end surface of the workbench 101, the positioning block 401a is provided with a hollow groove 401b, a fixing rod 401c is fixedly connected in the hollow groove 401b, a positioning plate 401d is detachably mounted on the fixing rod 401c, the auxiliary member 402 includes a positioning groove 402a arranged in the positioning plate 401d, a locking plate 401d is fixedly connected in the positioning groove 402a 02b, a screw rod 402c402c is rotatably connected in the locking plate 402b, and a threaded sleeve 402d is externally threadedly connected to the screw rod 402c, a limiting groove 402e is provided in the positioning groove 402a, and a limiting block 402f is slidably connected in the limiting groove 402e, and one end of the limiting block 402f is fixedly connected to the outer wall of the threaded sleeve 402d, and a connecting plate 402g is fixedly connected to the side wall of the threaded sleeve 402d, and an oblique hole 402h is provided on the upper end surface of the connecting plate 402g;

[0052] Since the steel bar has a certain elasticity, it will rebound after being bent. The present invention increases or decreases the reserved bending angle, so that the bending angle is corrected after the steel bar is bent, thereby providing a slightly larger target bending angle when the steel bar is bent, so that the steel bar can reach the desired angle after rebounding. Figures 7 to 10 It can be seen that a long strip-shaped positioning plate 401d is fixedly connected in the positioning block 401a, a hollow positioning groove 402a is provided in the positioning plate 401d, a locking plate 402b is fixedly connected in the positioning groove 402a, a screw rod 402c and a wire sleeve 402d are provided in the positioning groove 402a, and one end of the wire sleeve 402d is fixedly connected to a limiting block 402f, and the limiting block 402f is correspondingly slidably connected in the limiting groove 402e, thereby limiting the rotation direction of the wire sleeve 402d, thereby driving the wire sleeve 402d to perform linear motion on the outer wall of the screw rod 402c, and thus driving the connecting plate 402g to move synchronously while the wire sleeve 402d moves;

[0053] The adjusting member 403 includes an adjusting rod 403a disposed in the inclined hole 402h, an adjusting plate 403b is fixedly connected to the upper end surface of the adjusting rod 403a, a movable opening 403c is disposed in the positioning groove 402a, and one end of the adjusting plate 403b passing through the movable opening 403c is fixedly connected to a base plate 403d, a protective block 403e is disposed on the outer wall of the positioning plate 401d, and an adjusting spring 403f is distributed and fixedly connected between the protective plate 303e and the base plate 403d, and the adjusting spring 403f is a carbon spring with high strength and convenient for daily use;

[0054] Depend on Figures 7 to 10It can be seen that the upper end surface of the connecting plate 402g is provided with a long strip-shaped inclined hole 402h, and the corresponding sliding connection of the inclined hole 402h is provided with an adjusting rod 403a, and the upper end surface of the adjusting rod 403a is fixedly connected with an adjusting plate 403b. When the screw rod 402c is rotated, and the screw rod 402c and the wire sleeve 402d are threadedly connected, the wire sleeve 402d is slidably connected in the second limiting groove 402e through the limit block 402f, thereby limiting the rotation direction of the wire sleeve 402d, thereby driving the wire sleeve 402d to perform linear motion on the outer wall of the screw rod 402c, and at this time, the connecting plate 402g moves synchronously. It can be seen from the above that since the adjusting plate 403b can only perform linear motion in the horizontal direction in the movable opening 403c, the base plate 403d on the adjusting plate 403b is driven to move, thereby achieving the required angle after the steel bar rebounds;

[0055] Working principle: It can be seen from Example 1 that in order to adapt to the angles reached by different steel bars after rebound, the present invention adjusts the different positions of the base plate 403d to give the steel bars a corresponding reserved curvature, specifically by rotating the screw rod 402c, the screw rod 402c drives the wire sleeve 402d to rotate, and the limit block 402f on the wire sleeve 402d slides in the limit groove 402e, thereby limiting the rotation direction of the wire sleeve 402d, thereby driving the wire sleeve 402d to make linear motion on the outer wall of the screw rod 402c, and at this time the connecting plate 402g moves synchronously, because the adjustment plate 403b can only make linear motion in the horizontal direction in the movable opening 403c, thereby driving the base plate 403d on the adjustment plate 403b to move, thereby achieving the required angle after the steel bar rebounds, and when the steel bar is taken out, the steel bar will rebound slightly after bending deformation, and the bending angle of the steel bar after rebounding is the required bending angle.

[0060] Working principle: The present invention sets a grinding roller 114 so that the grinding roller 114 rotates as the steel bar moves during bending, and the grinding roller 114 fixes the steel bar while transporting the bent steel bar. At the same time, the device sets a protective shell 115 and an air pump to collect the debris generated by the bent steel bar, avoiding the debris from being scattered all over the main body, thereby improving the efficiency of debris collection.
