The common rectangular frame forming method on the market is to use strip-shaped raw materials, manually bend the corners multiple times, and finally form a rectangular frame structure. The product quality is highly affected by the proficiency of the operators and the product quality is difficult to guarantee. The inventor aims to provide a technical solution to solve this problem. Utility Model Content

[0004] The purpose of the utility model is to provide a frame bending and forming device, which has the advantage of replacing manual bending and forming of the frame.

[0005] To achieve the above-mentioned and other related purposes, the present invention provides the following technical solutions: a frame bending and forming device, comprising a support body, and further comprising:

[0006] A connecting piece fixed to the supporting body;

[0007] A conveying component sequentially conveys a fixed amount of strip-shaped raw materials to the overlapping pieces so that the strip-shaped raw materials overlap the overlapping pieces;

[0008] A rotating frame hinged to the support body, a bending member is fixed on the rotating frame, and a portion of the strip material to be bent is located on a moving path of the bending member;

[0009] A rotary driving member, used for driving the rotating frame to rotate after the strip material is overlapped on the overlapped member so that the bending member applies a bending force to the strip material; and

[0011] Through the above technical solution, when working, the conveying component will convey the strip material to the top of the joint piece in a quantitative manner, and stop conveying after completing the quantitative conveying. Then the rotating drive component drives the rotating frame to rotate, and drives the bending component to apply extrusion force to the strip material to make the strip material bend the first corner. Then the conveying component will convey the strip material in a quantitative manner again and perform subsequent corner bending. After bending at least three times, the strip material can be connected end to end to form a frame structure. Then the cutting component will cut off the excess strip material to complete the bending of the frame.

[0012] In one embodiment of the present invention, the conveying assembly includes: an active conveying wheel, a driven conveying wheel and a conveying drive member. The strip material passes between the active conveying wheel and the driven conveying wheel. The driven conveying wheel applies a pressing force to the strip material directed toward the driven conveying wheel. The conveying drive member drives the active conveying wheel to drive the strip material to move.

[0013] Through the above technical solution, the conveying drive member drives the active conveying wheel to rotate, and the active conveying wheel drives the strip material to move by utilizing the friction force with the strip material.

[0014] In one embodiment of the present invention, the cutting assembly includes: a cutting die fixed to the support body; a cutting drive installed on the support body; and a cutter driven by the cutting drive to slide and cooperate with the cutting die to cut the strip material.

[0016] In one embodiment of the present invention, the rotary driving member is configured as a driving cylinder, a cylinder body of the driving cylinder is hinged to the supporting body, and a piston rod is hinged to the rotating frame.

[0017] Through the above technical solution, the driving cylinder can provide sufficient pressure to enable the bending part to exert sufficient extrusion force on the strip material to deform and bend the strip material.

[0018] In one embodiment of the present invention, a material receiving assembly for receiving the formed frame blanks is further included.

[0019] The above technical solution makes it convenient to collect and organize the formed products.

[0020] In one embodiment of the present invention, the material receiving assembly includes:

[0021] A material introduction channel is fixed to the support body and arranged obliquely, and a material receiving box is arranged below the material introduction channel. The material introduction channel is used to introduce the fallen forming frame into the material receiving box; and a pushing piece is used to push the forming frame from the connecting piece into the material introduction channel.

[0022] Through the above technical solution, after the frame is formed, the pushing piece pushes the frame to move, pushes the frame off the overlapping piece, makes the frame fall into the material introduction channel, and enters the material receiving box through the material introduction channel for collection.

[0023] In one embodiment of the present invention, the pushing member is configured as a pushing cylinder.

[0024] Through the above technical solution, the push cylinder or the piston rod moves to push the frame to move.

[0025] As described above, the frame bending and forming device of the present invention has the following beneficial effects:

[0026] During operation, the conveying component conveys the strip material to the top of the joint piece in a quantitative manner, and stops conveying after completing the quantitative conveying. Then the rotating drive component drives the rotating frame to rotate, and drives the bending component to apply extrusion force to the strip material to make the strip material bend the first corner. Then the conveying component conveys the strip material in a quantitative manner again, and bends the subsequent corners. After bending at least three times, the strip material can be connected end to end to form a frame structure. Then the cutting component cuts off the excess strip material to complete the bending of the frame. BRIEF DESCRIPTION OF THE DRAWINGS
