Description

Technical Field

[0001] The present invention relates to the technical field of mechanical manufacturing, in particular to a steel bar support forming device. Background Art

[0002] With the development of society, construction plays a vital role in the national economy. Steel bars and cement are essential components of these projects. Traditional construction methods involve securing a bundled steel frame to designated locations within the formwork using prefabricated cement strips and plastic supports. Only when the steel bars are positioned in the designated cement locations can they achieve their maximum strength; otherwise, the quality of the project is significantly compromised. Therefore, cement strips and plastic supports are crucial components in construction. However, as my country's quality standards for construction projects continue to rise, issues with cement strips have emerged. For example, 1. Cement strips fail to provide a watertight seal when used in underground projects; 2. Production methods are chaotic and quality control is difficult; 3. They are bulky, heavy, and inconvenient to transport; and 4. They have a high breakage rate. Consequently, a product, steel bar supports, emerged as an alternative to cement strips and plastic supports. Steel bar supports meet all these requirements while addressing the shortcomings of cement strips and plastic supports. However, the production efficiency of steel bar supports is limited.

[0003] Existing rebar bending equipment performs wire feeding and then shaping. This results in very low production speeds. Furthermore, some existing rebar bending equipment uses molds with asymmetrical torque points or a single mold. This results in uneven torque, shortening the lifespan of the molds and multiple mechanisms when producing large components. Furthermore, the single mold requires a separate mold for each model, resulting in high mold costs and limiting production. Summary of the Invention

[0032] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0033] like Figures 1 to 5 As shown, a steel bar support forming device of the present invention includes a frame 100, and a cutter assembly 1, a mold assembly 2, a mold drive mechanism connected to the mold assembly, and an ejection assembly 6, which are sequentially arranged on the frame 100, wherein a plurality of mold assemblies 2 are provided, and the plurality of mold assemblies are slidably arranged on the frame. In this embodiment, two mold assemblies 2 are provided, and the two sets of mold assemblies 2 are spaced apart and arranged axially symmetrically. It should be noted that the two sets of mold assemblies 2 are slidably connected on the frame 100, so that the spacing between the two sets of mold assemblies 2 can be adjusted to facilitate the production of different types of steel bar supports, making the steel bar support forming device more versatile. It should be noted that the sliding method of the two sets of mold assemblies 2 on the frame 100 in this embodiment can be achieved by a screw and nut mechanism, or by a gear rack mechanism, as long as stable sliding can be achieved, and this embodiment is not limited to this. In addition, in other embodiments, other numbers of mold assemblies 2 can be provided.

[0034] The steel bar support forming device is also provided with a material preparation position and a mold position, wherein the material preparation position is used to place the raw materials to be bent, and the mold position is used to bend the raw materials.

[0035] The steel bar support forming device in this embodiment also includes a wire feeding mechanism, which is used to transport the raw materials to the preparation position.

[0036] The cutter assembly 1 includes a fixed blade holder 11, a cutter 12, and a cutter drive mechanism 1313. The fixed blade holder 11 is fixedly mounted on the frame 100. The cutter 12 is connected to the cutter drive mechanism 1313. The cutter drive mechanism 1313 is capable of driving the cutter 12 to reciprocate between the material preparation position and the mold position, cooperating with the fixed blade holder 11 to shear the raw material. Specifically, driven by the cutter drive mechanism 1313, one end of the cutter 12 extends into the blade holder and moves within the fixed blade holder 11. When the cutter 12 carries the raw material from the material preparation position to the mold position, the cutter 12 extends into the fixed blade holder 11 and continues to move, thus completing the shearing of the raw material. The cutter 12 is provided with a through hole. When the feed structure delivers the raw material to the material preparation position, the raw material is positioned within the through hole, thereby placing the raw material on the material preparation position. When the cutter 12 moves, the raw material moves with it until it moves to the mold position and is bent.

[0037] The mold assembly 2 includes a first bending part 21, a second bending part 22 and a third bending part 23. The mold driving mechanism includes a first mold driving mechanism 24 connected to the first bending part 21, a second mold driving mechanism 25 connected to the second bending part 22 and a third mold driving mechanism 26 connected to the third bending part 23.

The cutter 12 is located on one side of the first bending portion 21 of the mold assembly 2, and the second bending portion 22 of the mold assembly 2 is located on the other side of the first bending portion 21. The third bending portion 23 is adjacent to and opposite to the second bending portion 22. The second bending portion 22 includes a protrusion 221 and a clamping plate 222 connected to the protrusion 221. The protrusion 221 protrudes from the clamping plate 222 toward the third bending portion 23, and the third bending portion 23 is directly opposite the clamping plate 222. When the molds of the two sets of mold assemblies 2 bend the raw material, the first bending portion 21 and the second bending portion 22 both move toward the third bending portion 23.

[0039] When the cutter drive mechanism 1313 drives the cutter 12 from the material preparation position to the die position, the material moves with the cutter 12 to the die position, and the cutter 12 cooperates with the fixed cutter holder 11 to cut the material. Then, the second bending portions 22 of the two sets of mold assemblies 2 simultaneously move toward the material, so that the second bending portions 22 perform a first symmetrical bend on both sides of the material. After the first bend, two symmetrical first bends are formed on the material, and the protrusions 221 and the clamping platform 222 of the second bending portions 22 of the two sets of molds press the first bends. Subsequently, the third bending portions 23 of the two sets of molds move toward the material and perform a second symmetrical bend on both sides of the material. After the second bend, two symmetrical second bends are formed on the material. The second bends are located between the clamping platform and the third bending portion 23 and are pressed by both. Then, the first bending portions 21 of the two sets of mold assemblies 2 move toward the material and perform a third symmetrical bend on both sides of the material. After the third bend, the two ends of the material are 90 degrees to the original direction. In this embodiment, two sets of molds bend the raw material three times to complete the production operation from raw material to steel bar support.

[0049] In the steel bar support forming device, a cam-link mechanism simultaneously drives the first bending portion 21, the second bending portion 22, and the third bending portion 23. The cam-link mechanism's push stroke and return stroke achieve reciprocating motion of the first bending portion 21, the second bending portion 22, and the third bending portion 23, thereby achieving multi-point coordinated motion of the forming device, achieving the effects of strong working stroke force, fast return stroke, low noise, and high efficiency. In the prior art, multiple sets of molds are generally provided at multiple stations. During the raw material forming process, the raw material needs to be placed in sequence at multiple stations and bent by multiple sets of molds, which greatly prolongs the forming time and reduces production efficiency. In addition, the forming device in the prior art cannot simultaneously complete material preparation and mold forming. The raw material needs to be cut before it is transported to the mold position for bending. However, the forming device in this embodiment can also simultaneously prepare the material during the bending forming process. The shearing and bending forming are located at the same station, which improves the production efficiency of the forming device.

The fourth slider 1351 is located within the fourth slot 1361 and can slide along the fourth cam 1362 within the fourth slot 1361 of the fourth drive plate 136, thereby enabling the cutter drive mechanism 1313 to periodically and intermittently drive the cutter 12. The first rocker arm 134 and the second rocker arm 135 are located at opposite ends of the support shaft 3. The first drive frame 245, the second drive frame 255, and the third drive frame 268 are located between the first rocker arm 134 and the second rocker arm 135 and are arranged sequentially.

The first end of the rocker 132 is hinged to the first arm 131, the second end is hinged to the second arm 133, and the third end is rotatably connected to the cabinet 200.

[0051] In this embodiment, the fixed connection points between the support shaft 3 and the first rocker 134, and between the support shaft 3 and the second rocker 135, are both square shafts, thereby achieving a fixed connection between the rocker and the support shaft 3. When the second rocker 135 rotates on the drive shaft of the fourth drive disk 136, it drives the support shaft 3 to rotate, and the first rocker 134 swings accordingly. The swinging of the first rocker 134 drives the second arm 133 to swing, and the second arm 133 drives the rocker 132 to rotate. The rotation of the second arm 133 drives the first arm 131 to move in the direction from the material preparation position to the mold position, thereby enabling the cutter 12 to reciprocate within the cutter holder, thereby completing the pushing and shearing of the raw material.

[0052] The steel bar support forming device provided in this embodiment further includes a limit block 4 and a limit assembly 5. The limit block 4 is fixed to the second fixed block. The limit assembly 5 includes a push plate 51 and a push plate drive mechanism 52.

Specifically, the first push rod 521 passes through the pin and is fixedly connected to the pin. One end of the pin is rotatably connected to the fixed base. In addition, in this embodiment, a square shaft is provided on the frame 100 to realize the rotational connection between the first transmission plate 525 and the rocking block 132. Specifically, one end of the square shaft is rotationally connected to the frame 100, and the other end is rotationally connected to the rocking block 132. The first transmission plate 525 is fixedly connected to the square shaft.

[0054] The ejection assembly 6 includes a plurality of pushers 61 and a push mechanism 62 connected to the pushers 61. The push mechanism 62 and the mold assembly 2 are located on either side of the frame 100. The push mechanisms 62 and pushers 61 are arranged in a one-to-one correspondence to ensure that the bent finished product can be smoothly ejected from the molding device. In this embodiment, two pushers 61 are provided, and two push mechanisms 62 are also provided, and are arranged in a one-to-one correspondence with the pushers 61. In other embodiments, the ejection assembly 6 can also be provided with other numbers. The push mechanism 62 includes a second push rod 621, a second fixing seat 622, a third drive arm 623, a fourth drive arm 624, and a second transmission plate 625. The second transmission plate 625 is fixedly connected to the square shaft. The fourth drive arm 624 is ball-jointed with the second transmission plate 625. The third drive arm 623 is ball-jointed with the fourth drive arm 624. The third drive arm 623 is hingedly connected to the second push rod 621. The second fixed base 622 is fixed to the frame 100. The second push rod 621 is rotationally connected to the second fixed base 622. The second push rod 621 passes through the frame 100, and the end of the second push rod 621 is fixedly connected to the push head 61. In this embodiment, the second push rod 621 is rotationally connected to the second fixed base 622 via a pin. Specifically, the second push rod 621 passes through the pin and is fixedly connected to the pin. One end of the pin is rotationally connected to the second fixed base 622. In addition, in this embodiment, the second transmission plate 625 is fixedly connected to the square shaft to achieve a rotational connection between the second transmission plate 625 and the rocker 132.

[0055] When the rocker 132 is driven and rotates on the cabinet 200, the square shaft rotates accordingly, thereby driving the first transmission plate 525 and the second transmission plate 625 to rotate simultaneously. When the main drive shaft 300 is driven and rotated, the fourth cam 1362 on the fourth drive plate 136 drives the fourth slider 1351 of the second rocker 135 to slide within the fourth slide slot 1361, causing the second rocker 135 to swing about the support shaft 3. During the push motion of the fourth slider 1351, that is, as the fourth slider 1351 moves from the closest point to the farthest point from the center of the fourth cam 1362, the swing of the second rocker 135 drives the support shaft 3 to rotate, thereby driving the first rocker 134 to swing. The first rocker 134 pushes the second arm 133 downward in a direction closer to the frame 100. The rocker 132 rotates downward accordingly and pushes the first arm 131, which in turn pushes the cutter 12 from the material preparation position to the mold position. During the return movement of the fourth slider 1351, that is, in the process of the fourth slider 1351 rod moving from the farthest point to the closest point from the center of the fourth cam 1362, the swing of the second rocker arm 135 drives the support shaft 3 to rotate, thereby driving the first rocker arm 134 to swing, and the first rocker arm 134 pushes the second arm 133 to move upward in the direction away from the frame 100, and the rocker block 132 rotates upward and pulls the first arm 131, and then the first arm 131 pulls the cutter 12 from the mold position to the preparation position.

[0056] During the pushing motion of the fourth slider 1351, the rocker 132 rotates downward, causing the square shaft to rotate accordingly. At this point, the first transmission plate 525 pushes the first arm 131 and the second arm 133 toward the frame 100, thereby pushing the push plate 51 away from the frame 100. The push plate 51 is pushed a preset distance, cooperating with the limit block 4 to position the raw material. Simultaneously, the second transmission plate 625 pushes the third and fourth arms toward the frame 100, thereby pushing the push head 61 away from the frame 100. The push head 61 pushes the formed steel bar support out of the forming device. Afterwards, during the return stroke of the fourth slider 1351, when the rocker 132 rotates upward, the cutter 12 retreats from the mold position to the material preparation position, and the raw material is re-delivered to the cutter 12. At this time, the square shaft rotates with the rocker 132, and the first transmission piece 525 pulls the first arm 131 and the second arm 133 in a direction away from the frame 100, thereby pulling the push plate 51 back to the initial position in the direction closer to the frame 100. At the same time, the second transmission piece 625 pulls the third arm and the fourth arm in a direction away from the frame 100, thereby pulling the push head 61 back to the initial position in the direction closer to the frame 100. This achieves the synchronous operation of material preparation and pushing, greatly shortening the molding time of the molding device and improving the production efficiency of the molding device.

[0057] It should be noted that, when the raw material is bent in the mold position, the raw material is first limited, then bent, and finally the bent steel bar support is pushed out of the forming device. Therefore, there is a time difference in the limiting and pushing processes. Therefore, in this embodiment, the first transmission plate 525 and the second transmission plate 625 are adjusted to different angles with the square axis to accommodate the time difference in the operation. This avoids the need to set up multiple mechanisms to achieve different functions in the related art. In this embodiment, only the angles of the first transmission plate 525 and the second transmission plate 625 need to be adjusted to achieve synchronous and non-simultaneous operation, thereby simplifying the structure of the forming device and achieving precision of the forming device.

[0058] The steel bar support forming device proposed in this embodiment includes no less than two sets of mold assemblies 2, a mold drive mechanism, a cutter assembly 1 and a cutter drive mechanism 1313, wherein no less than two sets of mold assemblies 2 are set at the same time to bend and form the raw material, making the mold modular and avoiding the multi-station operation of the forming device in the prior art to bend and form the raw material, and the spacing between the no less than two sets of mold assemblies 2 is adjustable, so that the forming device can produce a variety of different models of products at the same time, increasing applicability, while reducing the occupied space of the forming device and saving the cost of the device, and reducing the maintenance and use cost of the forming device; the mold drive mechanism, the cutter drive mechanism 1313 and the pushing mechanism 62 can be driven by the same main drive shaft 300 at the same time, so that the mold mechanism and the cutter assembly 1 can operate at the same time, greatly shortening the forming time of the forming device and improving the forming efficiency. In addition, a material preparation position and a mold position are provided on the steel bar support, so that the material preparation and mold forming operations are carried out simultaneously, realizing the simultaneous preparation and forming, thereby improving the production efficiency of the forming device.

These improvements and modifications should also be regarded as the scope of protection of the present invention.
