Description

Technical Field

[0001] The utility model relates to the technical field of bending machines, in particular to an adjustable bending machine. Background Art

[0002] A bending machine is a machine that can bend thin plates. In the production and processing of steel structure plates, due to the specific requirements of the product, it is often necessary to bend the steel plates at a certain angle.

When facing steel plates of different sizes and dimensions that need to be bent, it is not convenient to quickly replace the mold, resulting in reduced work efficiency. Moreover, most of the existing steel plate bending machines do not have a buffer function. The rapid impact force generated during the bending process will cause great damage to the mold, which is not conducive to ensuring the service life of the mold. For this reason, we propose an adjustable bending machine. Utility Model Content

[0028] exist Figure 1-Figure 4 In the embodiment, a buffer mechanism is arranged on a base 1 and a support frame 2, and the buffer mechanism includes four guide shafts 11 and eight telescopic rods 12. The four guide shafts 11 are fixedly connected between the base 1 and the support frame 2, and the eight telescopic rods 12 are fixedly connected to the base 1. The eight telescopic rods 12 are grouped in pairs, and a buffer spring 13 is arranged in the telescopic rod 12.

[0031] exist Figure 2 and Figure 4 In the embodiment, a buffer pad 17 is fixedly connected to the pressing plate 14 to protect the pressing plate 14 and avoid direct collision between the pressing plate 14 and the lifting plate 6.

[0032] exist Figure 1-Figure 3 In the embodiment, the base 1 is fixedly connected with an anti-skid pad 18 to increase the friction force and make the overall device more stable.

[0033] It should be further explained that the motor 9 and the hydraulic cylinder 3 in this embodiment are conventional equipment purchased on the market and known to those skilled in the art. The models can be selected or customized according to actual needs. In this patent, we only use them and do not improve their structure and function. For technicians in this field, their setting method, installation method and electrical connection method only need to be debugged according to the requirements of their instruction manual, and will not be described in detail here. The motor 9 and the hydraulic cylinder 3 are provided with matching control switches. The installation position of the control switch is selected according to actual use requirements to facilitate the operator to operate and control.

[0034] In summary, the working principle and working process of the adjustable bending machine are as follows: when in use, the adjustable bending machine is first placed at the desired location, and the motor 9 is connected to the forward and reverse circuit according to the instructions. Then, when the mold needs to be replaced, people can start the motor 9, and the motor 9 will drive the bidirectional threaded shaft 8 to rotate. The bidirectional threaded shaft 8 drives the two sliders 7 to move away from each other in the slide groove, and then the slider 7 drives the card block 10 to move out of the card groove, so that people can replace the upper mold 4 or the lower mold 5. After replacement, when using, put the plate into the lower mold 5, and then start the hydraulic cylinder 3. The hydraulic cylinder 3 drives the lifting plate 6 to descend, so that the lifting plate 6 drives the upper mold 4 to press on the lower mold 5, so that the processing of the plate can be completed. In the process of the lifting plate 6 falling, the lifting plate 6 hits the buffer pad 17 and the pressing plate 14. The buffer pad 17 can avoid direct collision between the pressing plate 14 and the lifting plate 6, and then the pressing plate 14 will compress the telescopic rod 12, and the buffer spring 13 in the telescopic rod 12 will buffer the impact force, thereby facilitating the improvement of the service life of the upper mold 4 and the lower mold 5.

[0035] The above embodiments only express the specific implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
