Technical Field

[0001] The utility model relates to the technical field of iron cabinet processing, and specifically relates to a bending machine for a new type of intelligent iron cabinet. Background Technique

[0002] An iron cabinet is a cabinet made of cold-rolled steel plates (commonly known as iron sheets). Its characteristics are relatively light weight compared to wooden cabinets, easy to move, and fireproof, moisture-proof, insect-proof, mothproof, and corrosion-proof.

[0003] Currently, a hydraulic bending machine is needed to bend iron sheets during the production of iron cabinets. When the existing hydraulic bending machine is in use, workers need to insert the iron sheets into the internal part of the hydraulic bending machine. Since the contact area between the mold of the hydraulic bending machine and the iron sheet is reduced, the end of the iron sheet is in a suspended state during the bending process of the mold of the hydraulic bending machine, which easily causes deformation of the iron sheet and requires workers to hold up the iron sheet. Therefore, improvement is needed. Content of the Utility Model

[0004] The purpose of the utility model is to provide a bending machine for a new type of intelligent iron cabinet to solve the problem that the end of the iron sheet is easily suspended and deformed during the bending process of the iron sheet as mentioned in the above background technique.

[0010] Preferably, chutes are provided on both sides of the frame body, and sliders are provided on both sides of the hydraulic frame. The sliders are inserted into the chutes, and the hydraulic frame is slidably connected to the frame body through the sliders and the chutes.

[0011] Preferably, a pressurizing hydraulic cylinder is fixedly connected to the top end of the frame body, a groove is formed at the top end of the hydraulic frame, and one end of the pressurizing hydraulic cylinder is connected to the top end of the hydraulic frame.

Sliding grooves 8 are provided on both sides of the frame body 4, and sliding blocks 7 are provided on both sides of the hydraulic frame 1. The sliding blocks 7 are inserted into the sliding grooves 8, and the hydraulic frame 1 is slidably connected to the frame body 4 through the sliding blocks 7 and the sliding grooves 8; this structure can improve the stability of the hydraulic frame 1 during the sliding process by setting the sliding grooves 8 and the sliding blocks 7. The top end of the frame body 4 is fixedly connected to a pressurizing hydraulic cylinder 6. A groove is opened at the top end of the hydraulic frame 1, and one end of the pressurizing hydraulic cylinder 6 is connected to the top end of the hydraulic frame 1; this structure can push the hydraulic frame 1 to automatically press down for bending work through the pressurizing hydraulic cylinder 6. A side-pushing hydraulic cylinder 10 is provided at the front end of the frame body 4, and one end of the side-pushing hydraulic cylinder 10 is connected to a limiting plate 9, and the limiting plate 9 is located at one end of the iron sheet to be processed 5; this structure can push the position of the limiting plate 9 to be adjusted through the side-pushing hydraulic cylinder 10, and the insertion depth of the iron sheet to be processed 5 can be adjusted through the limiting plate 9, playing a role in limiting the iron sheet to be processed 5. A bending upper die 2 is provided at the bottom of the hydraulic frame 1. A groove is opened at the lower end of the frame body 4, and a bending lower die 12 is provided inside the groove. The bottom of the bending lower die 12 is connected to a jacking hydraulic cylinder 11. The bending lower die 12 is located at the bottom of the bending upper die 2, and a support assembly 3 is provided at one end of the frame body 4; the height of the bending lower die 12 can be adjusted through the jacking hydraulic cylinder 11, and it can cooperate with the hydraulic frame 1 during bending operation;

[0023] The support component 3 includes a support plate 32 rotatably connected to one end of the frame body 4. The support plate 32 is of a hollow structure. A flow dividing plate 33 is inserted at the bottom of the support plate 32. An adsorption head 36 is provided on the flow dividing plate 33. The top end of the adsorption head 36 is of a mesh structure, and the width of the adsorption head 36 is smaller than the width of the iron sheet 5 to be processed; this is convenient for ensuring the sealing performance during the adsorption process; with this structure, the iron sheet 5 to be processed can be adsorbed on the top of the support plate 32 through the adsorption head 36; one end of the flow dividing plate 33 is connected to the support plate 32. An electromagnetic valve 37 is provided on the flow dividing plate 33. One end of the flow dividing plate 33 is connected to a negative pressure fan 34.

[0024] Working principle: When using the bending machine of this new - type intelligent iron cabinet, first, the side - pushing hydraulic cylinder 10 pushes the limiting plate 9 to move to a suitable position. Then, the iron sheet 5 to be processed is placed on the support plate 32 and the iron sheet 5 to be processed is pushed so that one end of the iron sheet 5 to be processed is inserted between the bending upper die 2 and the bending lower die 12. Then, the negative pressure fan 34 and the electromagnetic valve 37 are turned on. After the negative pressure fan 34 is turned on, negative pressure is generated at the flow dividing plate 33 and the adsorption head 36, so that the adsorption head 36 adsorbs and fixes the iron sheet 5 to be processed. Then, the pressure - adding hydraulic cylinder 6 pushes the hydraulic frame 1 to descend, so that the bending upper die 2 approaches the iron sheet 5 to be processed. When the bending upper die 2 contacts the iron sheet 5 to be processed, the driving motor 31 drives the support plate 32 to rotate. During the rotation of the support plate 32, it slowly rises. At the same time, the end of the iron sheet 5 to be processed also rises upward after being bent, so that the support plate 32 maintains the support for the iron sheet 5 to be processed, avoiding the iron sheet 5 to be processed from being suspended.
