DETAILED DESCRIPTION
[0020] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0021] See also Figure 1-5 A soft steel bar cutting device for construction engineering comprises a clamp barrel 1, one end of the clamp barrel 1 is fixedly connected with a handle 2, the end of the clamp barrel 1 away from the handle 2 is fixedly connected with a clamp body 3, a front clamp knife 4 is arranged on the inner side of the clamp body 3, a fixing seat 5 is fixedly connected with the top of the clamp barrel 1, a rotating shaft 6 is fixedly penetrated on the inner side of the fixing seat 5, a pressing handle 7 is rotatably connected to the outer surface of the rotating shaft 6, an end of the clamp barrel 1 close to the clamp body 3 is slidably sleeved with a push rod 8 through a driving mechanism, and a rear clamp knife 9 is arranged on the end of the push rod 8 close to the front clamp knife 4.
[0022] Through the above technical solution, when using the device, the appropriate part of the soft steel bar is placed between the front pliers 4 and the rear pliers 9, and then the handle 2 is held and the pressure handle 7 is pressed. Through the driving mechanism, the rear pliers 9 can be moved close to the front pliers 4 via the push rod 8. The two sets of pliers can cooperate to achieve precise cutting of the soft steel bar.
[0023] Specifically, the driving mechanism includes a tube 10 fixedly inserted on the top of the clamp tube 1, a shift rod 11 is slidably sleeved on the inner surface of the tube 10, and a spring 12 is movably sleeved on the outer surface of the shift rod 11.
[0024] Through the above technical solution, when the shift rod 11 moves up and down, the spring 12 will produce a certain deformation. Here, the spring 12 assists in pressing down and allows the rear pliers 9 to return to their original position after cutting.
[0025] Specifically, the top of the shift rod 11 is fixedly connected with a connecting seat 13 , the inner side of the connecting seat 13 is fixedly connected with a pressing shaft 14 , and the outer surface of the pressing shaft 14 is rotatably connected to the inner surface of the pressing handle 7 .
[0026] Through the above technical solution, the shift rod 11 can be pulled up or pressed down by the pressing shaft 14 cooperating with the connecting seat 13, thereby cooperating with the driving bar frame 15 for linkage.
[0027] Specifically, the bottom end of the shift rod 11 is rotatably connected to a driving bar frame 15 , and the interior of the clamp barrel 1 is fixedly connected to a fixed shaft 16 .
[0028] Through the above technical solution, the fixed axis 16 remains stable during the entire cutting process, and can cooperate with the rear swing bar 17 and the driving bar frame 15 to drive the front swing bar 18.
[0029] Specifically, the outer surface of the fixed shaft 16 is rotatably connected to a rear swing bar 17, and one end of the rear swing bar 17 away from the fixed shaft 16 is rotatably connected to the bottom end of the driving bar frame 15, and the bottom end of the driving bar frame 15 is rotatably connected to a front swing bar 18, and a guide rail 19 is provided inside the clamp barrel 1.
[0030] Through the above technical solution, the function of the guide rail 19 is to allow the slide 20 to maintain a fixed track displacement after being driven by the front swing bar 18.
[0031] Specifically, a slide 20 is slidably connected to the inner side of the guide rail 19, and the outer surface of the slide 20 is fixedly connected to the end of the push rod 8 away from the rear clamp 9. A shaft 21 is fixedly penetrated through the inner side of the slide 20, and the outer surface of the shaft 21 is rotatably connected to the end of the front swing bar 18 away from the driving bar frame 15.
[0032] Through the above technical solution, when the front swing bar 18 pulls the slide 20 through the table shaft 21, the slide 20 will not move up and down, but will only slide forward and backward along the inner side thereof under the relative limiting effect of the guide rail 19.
[0033] Working principle: When the device is in use, the operator can directly touch and control the position and angle of the steel bar, and can more accurately align the pliers to the position where cutting is required, that is, place the appropriate part of the soft steel bar between the front pliers 4 and the rear pliers 9, then hold the handle 2 and press the pressure handle 7 at the same time. During this process, the pressure handle 7 will rotate along the rotating shaft 6, and at the same time, the pressure shaft 14 will cooperate with the connecting seat 13 to allow the shift rod 11 to pass through the tube 10 and slide down. During this period, the spring 12 will be compressed, and the shift rod 11 will drive the driving bar frame 15 to deflect it during the downward movement, and with the assistance of the fixed shaft 16, the rear swing bar 17 will rotate along the fixed shaft 16, and at the same time, the bottom end of the driving bar frame 15 will push the front swing bar 18, so that the front swing bar 18 rotates along the table shaft 21 , drive the slide 20 to slide forward along the inner side of the guide rail 19, and while the slide 20 slides, the rear pliers 9 will be pushed by the push rod 8, so that the rear pliers 9 gradually approach the front pliers 4, and the two sets of pliers can cooperate to accurately cut the soft steel bars. This manual control makes it possible to fine-tune the position of the steel bars before cutting to ensure the precise alignment of the incision, and the operator can adjust the clamping force and angle of the manual pliers in real time according to the actual situation, directly observe the position and shape of the steel bar incision, and make adjustments and corrections at any time, so that any deviations can be discovered and corrected in time to ensure the accuracy and consistency of the incision. In contrast, the steel bar cutting machine usually needs to set the cutting parameters in advance, and it is difficult to flexibly adjust them in real time during the cutting process.
[0034] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
