[0012] The beneficial effects of the present utility model:

[0013] The present utility model provides a four-column automatic stretching machine for stainless steel containers. By setting a servo motor and controlling the start of the servo motor, when the servo motor rotates clockwise, it can drive the threaded rod to rotate clockwise in the threaded hole opened in the cross plate.

[0014] The present utility model provides a four-column automatic stretching machine for stainless steel containers. By setting a cylinder, when the guide post rises, that is, after the stainless steel container is formed, as the connecting plate rises, it can drive the plug disk to move upward inside the cylinder under the action of the L-shaped frame, thereby generating negative pressure inside the cylinder and sucking the protective oil into the cylinder. When the guide post moves downward, it can drive the L-shaped frame to move downward, press the protective oil inside the cylinder into the oil outlet pipe, and finally spray it downward from the spray head below the guide post and then scatter it on the outer surface of the profile, so that the profile can be well protected during the forming process.

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Please refer to Figures 1 - 4 , the present utility model provides a four-column automatic stretching machine for stainless steel containers, including a bottom box 1, a top box 3 is arranged above the bottom box 1, a guide post 4 is fixedly connected between the top box 3 and the bottom box 1, a forming frame 5 is movably installed on the outer surface of the guide post 4, a forming table 2 is arranged inside the bottom box 1, a stripping box 6 is installed on the bottom surface of the forming table 2, a clamping table 7 is installed inside the forming table 2, limiting grooves are opened on both inner walls of the bottom box 1, and clamping plates 8 are fixedly installed on both sides of the forming table 2, and the clamping plates 8 are movably clamped inside the limiting grooves.

[0023] During operation, the profile to be formed is placed on the top surface of the clamping table 7, and then by controlling the downward movement of the forming frame 5 until it contacts and presses the profile placed on the top surface of the clamping table 7, the forming operation of the profile can be completed, and finally the formed stainless steel container can be taken out. The above is already a mature prior art, so no detailed description will be given.

[0024] Two connecting plates 9 are fixedly installed on the bottom surface of the stripping box 6, a cross plate 10 is fixedly installed between the two connecting plates 9, a threaded hole is opened inside the cross plate 10, a threaded rod 11 is threadedly sleeved inside the threaded hole, a servo motor 12 is arranged on the rear surface of the bottom box 1, the output end of the servo motor 12 is fixedly connected to one end of the threaded rod 11, and a mounting frame 13 is fixedly installed on the rear surface of the bottom box 1, and the servo motor 12 is fixedly installed inside the mounting frame 13.

[0025] During operation, after the forming is completed, the servo motor 12 can be started by control. When the servo motor 12 rotates clockwise, it can drive the threaded rod 11 to rotate clockwise in the threaded hole opened in the cross plate 10. Then, under the action of the thread, it drives the forming table 2 to move out of the bottom box 1. During the movement, the stability of the movement of the forming table 2 can be ensured by the provided clamping plate 8. As the forming table 2 continues to move, until the forming table 2 completely moves out from below the guide post 4, the formed stainless steel container can be taken out and a new profile can be placed. After the new profile is placed, the servo motor 12 can be rotated counterclockwise by control to drive the threaded rod 11 to rotate synchronously, and the forming table 2 can be moved back under the guide post 4. Thus, the purpose of ensuring the safety of the operator by moving the forming table 2 away from below the guide post 4 during the loading and unloading process is achieved, and the safety of the operator during use is greatly improved.

[0026] Furthermore, as Figures 1 - 4 shown, both ends of the top surface of the bottom box 1 are fixedly installed with cylinders 14, the rear surface of the bottom box 1 is fixedly installed with an oil storage tank 15, an oil delivery pipe 16 is fixedly connected between the cylinder 14 and the oil storage tank 15, a check valve one 17 is fixedly installed on the outer surface of the oil delivery pipe 16, fixed frames 18 are fixedly installed on both side surfaces of the guide post 4, a flow dividing frame 19 is fixedly installed at the bottom end of the fixed frame 18, and a plurality of nozzles 20 are equidistantly installed on one side surface of the flow dividing frame 19. A plug disk 24 is movably clamped inside the cylinder 14, an oil outlet pipe 22 is fixedly connected to one side surface of the cylinder 14, the other end of the oil outlet pipe 22 is fixedly connected to the bottom surface of the flow dividing frame 19, a check valve two 23 is fixedly installed on the outer surface of the oil outlet pipe 22, an L-shaped frame 21 is fixedly connected to the top surface of the plug disk 24, and one end of the L-shaped frame 21 is fixedly connected to one side surface of the guide post 4.

[0027] During operation, when the guide post 4 rises, that is, after the stainless steel container is formed, as the connecting plate 9 rises, it can drive the plug disk 24 to move upward inside the cylinder 14 under the action of the L-shaped frame 21, so that a negative pressure is generated inside the cylinder 14. Under the action of the negative pressure, the protective oil inside the oil storage tank 15 is sucked into the cylinder 14 through the oil delivery pipe 16. During the process of forming the profile, that is, when the guide post 4 moves downward, it can drive the L-shaped frame 21 to move downward, press the protective oil inside the cylinder 14 into the oil outlet pipe 22, and finally enter the flow dividing frame 19, and then be sprayed downward from the nozzles 20 toward the guide post 4 and scattered on the outer surface of the profile, so that the profile can be well protected during the forming process, avoiding damage to the profile by the guide post 4 during the forming process and causing damage to the subsequent formed stainless steel container. The protective oil is a synthetic oil, composed of a synthetic base oil and additives, which belongs to the prior art and will not be elaborated too much.

[0028] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, making equivalent substitutions or changes should be covered within the protection scope of the present utility model.
