Description

Technical Field

[0001] This utility model relates to the field of steel bar processing technology, specifically to a steel bar bending device. Background Technology

[0002] Common pipe fixing connectors use specialized bending devices to bend the reinforcing bars. However, due to the lack of a corresponding traction structure, the bars need to be manually pulled onto the bending wheel before bending can be achieved. This process significantly reduces the efficiency of bending the reinforcing bars.

[0003] In this regard, the existing technology patent announcement number: CN209681001U discloses a rebar bending device, which includes a placement mechanism, a conveying and limiting mechanism disposed on one side of the placement mechanism, and a rebar bending mechanism disposed on the conveying and limiting mechanism.

[0004] However, in actual use, when bending the reinforcing bars, it is necessary to rotate the entire reinforcing bar before bending. Because the reinforcing bars are relatively hard, the force required for rotation is large, which can easily damage the rotating components. The overall operation is cumbersome. At the same time, it does not have a limiting and conveying effect when guiding the reinforcing bars. Therefore, improving and perfecting the above-mentioned problems has become an urgent issue to be solved. Utility Model Content

[0005] The purpose of this utility model is to provide a rebar bending device to solve the problems mentioned in the background art, which require rotating the rebar as a whole before bending. Because the rebar is hard, the force required for rotation is large, which can easily damage the rotating components. The overall operation is cumbersome, and the device does not have a limiting and conveying effect when guiding the rebar.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a bending device for bending reinforcing bars, comprising a base plate, a control panel mounted on the front surface of the base plate, a support plate mounted on the top surface of the base plate, a guide assembly and a bending assembly mounted sequentially from left to right on the upper surface of the base plate, and a cutting assembly mounted on the top surface of the base plate;

[0007] The guide assembly includes a support block, and a limit cylinder is installed on the right side of the support block;

[0008] The bending rib assembly includes a lower mold and a support frame. The lower mold and the support frame are respectively installed from front to back on the upper surface of the base plate. A first hydraulic cylinder is installed on the top surface of the support frame, and the lower end of the first hydraulic cylinder passes through the top surface of the support frame to install the upper mold.

[0009] Preferably, the inner wall of the limiting cylinder is provided with a groove, and an auxiliary ball bearing is installed inside the groove.

[0010] Preferably, a mounting motor is installed at the front end of the support plate, and a mounting plate is installed at the output end of the mounting motor through the interior of the support plate.

[0011] Preferably, the cutting assembly includes a cutting frame mounted on the top surface of the base plate.

[0012] Preferably, a top frame is mounted on the upper surface of the cutting frame, and a second hydraulic cylinder is mounted on the top surface of the top frame.

[0013] Preferably, a cutting blade is mounted on the lower end of the second hydraulic cylinder, penetrating the top surface of the top frame.

[0014] Preferably, the lower mold and the upper mold are mutually compatible.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This rebar bending device uses the upper mold to compress the rebar inside the lower mold, making the overall operation relatively convenient. Ultimately, the rebar is pressed into a specified curved structure. Therefore, this device, through the cooperation of the guide component and the bending component, can quickly guide and transport the rebar, facilitating the subsequent bending operation of the rebar by the bending component. The overall operation is relatively convenient.

[0017] The rebar bending device involves the operator feeding the rebar inside the lower mold to the right. The bent rebar then enters the upper surface of the cutting frame. The second hydraulic cylinder is then activated to drive the cutting blade downwards, cutting the length of the bent rebar. This process is repeated to quickly complete the rebar bending operation.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 One embodiment provided by this utility model:

[0026] A rebar bending device is disclosed in this application. The control panel 2, the mounting motor 4, and the second hydraulic cylinder 16 used in this application are all products that can be purchased directly from the market. Their principles and connection methods are existing technologies known to those skilled in the art, so they will not be described in detail here. The device includes a base plate 1, a control panel 2 installed on the front surface of the base plate 1, a support plate 3 installed on the top surface of the base plate 1, a guide assembly and a bending assembly installed on the upper surface of the base plate 1 from left to right, and a cutting assembly installed on the top surface of the base plate 1.

[0027] The guide assembly includes a support block 6, and a limit cylinder 11 is installed on the right side of the support block 6;

[0028] The rebar assembly includes a lower mold 7 and a support frame 8, which are installed from front to back on the upper surface of the base plate 1. A first hydraulic cylinder 9 is installed on the top surface of the support frame 8, and the lower end of the first hydraulic cylinder 9 penetrates the top surface of the support frame 8 to install an upper mold 10. A groove 12 is formed on the inner side wall of the limiting cylinder 11, and an auxiliary ball bearing 13 is installed inside the groove 12. An installation motor 4 is installed at the front end of the support plate 3, and an installation disc 5 is installed inside the support plate 3 through the output end of the installation motor 4. The entire coil of original rebar is placed on the outer surface of the installation disc 5. The installation motor 4 can drive the installation disc 5 to rotate, thereby conveying the rebar on the surface of the installation disc 5. The rebar will then pass through the support block 6 and the inside of the limiting cylinder 11 for stable conveying, resulting in a good overall conveying effect. When the rebar is conveyed inside the limiting cylinder 11, the groove 12 and the auxiliary ball bearing 13 can abut against the outer surface of the rebar, thereby assisting in the limiting conveying of the rebar.

[0029] The cutting assembly includes a cutting frame 14, which is mounted on the top surface of the base plate 1. A top frame 15 is mounted on the upper surface of the cutting frame 14, and a second hydraulic cylinder 16 is mounted on the top surface of the top frame 15. A cutting blade 17 is mounted on the lower end of the second hydraulic cylinder 16, penetrating the top surface of the top frame 15. After the reinforcing bars inside the lower mold 7 have completed the bending operation, the mounting plate 5 continues to rotate, allowing the operator to convey the reinforcing bars inside the lower mold 7 to the right. The bent reinforcing bars then enter the upper surface of the cutting frame 14, and the second hydraulic cylinder 16 is activated to drive the cutting blade 17 downwards, cutting the length of the bent reinforcing bars. This process is repeated to quickly complete the bending operation of the reinforcing bars.

[0030] The lower mold 7 and the upper mold 10 are compatible with each other. At the same time, the lower mold 7 and the upper mold 10 are compatible with each other, which can press the steel bars into curved bars. During operation, the upper mold 10 moves downward, which can stabilize the steel bars to a large extent.

[0031] Working principle: When the operator uses this device, first connect the device to an external power source to provide power support. Place the entire coil of raw steel bars on the outer surface of the mounting plate 5. The mounting motor 4 drives the mounting plate 5 to rotate, thereby conveying the steel bars on the surface of the mounting plate 5. Then, the steel bars will pass through the support block 6 and the limiting cylinder 11 for stable conveying, resulting in a good overall conveying effect. When the steel bars are conveyed inside the limiting cylinder 11, the groove 12 and the auxiliary ball 13 can abut against the outer surface of the steel bars, thereby assisting in the limiting conveying of the steel bars. Then, the steel bars are conveyed into the lower mold 7. At this time, by activating the first hydraulic cylinder 9, the first hydraulic cylinder 9 drives the upper mold 10 to press down. At this time, the upper mold 10 and the lower mold 7 are adapted to each other, so that the steel bars inside the lower mold 7 can be bent by the extrusion of the upper mold 10.

[0032] After the steel bars inside the lower mold 7 have completed the bending operation, the mounting plate 5 continues to rotate, so that the operator can transport the steel bars inside the lower mold 7 to the right. At this time, the steel bars that have completed the bending will enter the upper surface of the cutting frame 14. Then, the second oil cylinder 16 is started to drive the cutting blade 17 downward to cut the length of the steel bars that have completed the bending operation. The above is the working principle of this utility model.

[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
