Manual bending is that workers bend the steel plate by using a handheld portable bending device, which not only takes a lot of time, but also the bending effect varies greatly depending on the level of the operator. A steel plate bending device disclosed in an application with application number CN202122029483.6 includes a support mechanism, a bottom mold mechanism and a top mold mechanism; the support mechanism includes a support base, and two parallel first rails are symmetrically arranged on the top surface of the support base; support side plates are symmetrically fixedly arranged on both sides of the top surface of the support base in a direction perpendicular to the first rail, and a top plate is fixedly arranged on the top surface of the support side plates; the bottom mold mechanism is arranged on the top surface of the support base and between the two support side plates, for supporting the steel plate and adjusting the size of the bottom mold support; the top mold mechanism is arranged on the bottom surface of the top plate, for pressing the steel plate downward toward the bottom mold mechanism for bending. The steel plate bending device of the utility model can bend steel plates of different angles and punch grooves of different sizes by means of an adjustable ground film mechanism and a replaceable top die mechanism, and has strong versatility. However, the above application is inconvenient to take out the bent steel plate during use, and workers are prone to pinching their hands when manually taking out the steel plate.

DETAILED DESCRIPTION

[0024] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0025] like Figure 1-Figure 6 As shown, the steel plate bending machine provided in this embodiment includes a box body 1, and a box door 2 rotatably installed on the front side of the box body 1, a bottom mold 11 is installed at the bottom of the inner wall of the box body 1, a hydraulic cylinder 9 is installed at the top of the inner wall of the box body 1, and a top mold 10 is installed at the movable end of the hydraulic cylinder 9. Two first limiting rods 12 and second limiting rods 13 located above the bottom mold 11 are symmetrically installed inside the box body 1, and a first cylinder 5 and a second cylinder 6 are symmetrically installed on the back side of the box body 1, and the movable ends of the first cylinder 5 and the second cylinder 6 are both installed with push blocks 15 located on the inner side of the bottom mold 11. By configuring the first cylinder 5, the second cylinder 6 and the push block 15, the push block 15 can be driven to move by the first cylinder 5 and the second cylinder 6 during use, so that the steel plate bent on the inner side of the bottom mold 11 can be pushed out from the inner side of the bottom mold 11, without the need for workers to reach between the top mold 10 and the bottom mold 11 to take out the steel plate, thereby improving the safety of the operation. By configuring the first limit rod 12 and the second limit rod 13, both ends of the steel plate can be limited.

[0026] The first limiting rod 12 and the second limiting rod 13 are respectively located on both sides of the top mold 10. The back of the box body 1 is provided with a first mounting hole 7 and a second mounting hole 8 respectively cooperating with the first limiting rod 12 and the second limiting rod 13. The first mounting hole 7 and the second mounting hole 8 are waist-shaped holes. The first limiting rod 12 and the second limiting rod 13 both include a mounting rod 122. A rubber roller 121 is rotatably mounted on the outer side of the mounting rod 122. A fixing nut 123 located on one side of the rubber roller 121 is threadedly connected to the outer side of the mounting rod 122. The rubber roller 121 rotatably mounted on the mounting rod 122 during the bending process can reduce the friction between the steel plate and the steel plate by rotating during the process of limiting the position of the steel plate. When in use, the position of the mounting rod 122 inside the first mounting hole 7 and the second mounting hole 8 can be adjusted by loosening the two fixing nuts 123, so as to adjust the height of the rubber roller 121 to adapt to steel plates of different thicknesses. After the adjustment is completed, the two fixing nuts 123 are tightened to clamp the back of the box body 1 to complete the fixing of the position of the mounting rod 122.

[0027] A dust suction pipe 14 is installed through the back of the box 1, and a dust collector 4 cooperating with the dust suction pipe 14 is provided on one side of the box 1. The dust collector 4 is installed on the side wall of the box 1 through a push block 15, and a fan 3 located below the box door 2 is installed on the front of the box 1. During the bending process, the dust collector 4 is started to cooperate with the dust suction pipe 14 to suck out the iron filings that fly during bending from the inner side of the bottom mold 11. At the same time, the fan 3 is started to blow air from the iron filings inside the bottom mold 11, making it convenient for the dust collector 4 and the dust suction pipe 14 to suck the iron filings from the inside of the box 1.

[0028] In this embodiment, if Figure 1-Figure 6 As shown, the working process of a steel plate bending machine provided in this embodiment is as follows:

[0029] Step 1: When in use, place the steel plate on the top of the bottom mold 11, and then adjust the positions of the first limiting rod 12 and the second limiting rod 13 so that the first limiting rod 12 and the second limiting rod 13 are pressed on the top of the steel plate;

[0030] Step 2: At this time, start the hydraulic cylinder 9 to drive the top die 10 to move downward to cooperate with the bottom die 11 to bend the steel plate. After the bending is completed, start the hydraulic cylinder 9 to reset the top die 10, and then start the first cylinder 5 and the second cylinder 6 to drive the push block 15 to move and push the steel plate inside the bottom die 11 out.

[0031] The above is only a further embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the scope disclosed by the present invention according to the technical solution and concept of the present invention, which fall within the protection scope of the present invention.
