[0002] A steel structure pigsty is a pigsty built with a steel structure, mainly composed of a steel structure frame, walls, a roof, etc. It can bear large loads and has good load-bearing capacity. At the same time, it also has properties such as heat preservation, heat insulation, and sound insulation to prevent the smell in the pigsty from leaking out. Therefore, it is widely used in modern pig farming. When producing the steel sheets used in steel structure pigsties, a profiling machine is needed to press the sheets into a certain shape for convenient subsequent use of the steel sheets. In the prior art, because the weight of the steel sheets is large, it is inconvenient to load the sheets. Therefore, multiple loading rollers are provided at the loading position of the sheet metal profiling machine. Through the relative rotation of the rollers and the sheets, it is convenient to move the steel sheets. At the same time, in order to prevent the steel sheets from shifting, positioning components are also set to ensure the accurate loading position of the sheets. However, sometimes the sizes of the sheets to be profiled are different, and it is easy to have the situation where the sheets do not accurately contact the positioning components, which will affect the profiling quality of the steel sheets. Content of the Utility Model

While ensuring the smooth movement of the steel sheets, it makes the steel sheets accurately contact the positioning components, improves the accuracy of the loading position of the steel sheets, and ensures the processing quality of the sheet metal profiling machine.

[0007] Further, the feeding mechanism includes feeding rollers, and the feeding rollers are respectively rotatably connected between two feeding support plates through the third rotating shaft. The feeding rollers are horizontally and equidistantly distributed, which is convenient for feeding steel plates.

[0008] Further, the feeding mechanism further includes a screw rod, an adjusting plate and positioning columns.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Please refer to Figures 1-4 , this embodiment provides a technical solution: a plate press, including a support 1 and a loading mechanism 9;

[0022] Bracket 1: Sliders 2 are respectively and slidably connected in the chutes at the front and rear ends thereof, providing space for the movement of the mold. A upper pressing die 3 is rotatably connected between the two sliders 2 through a first rotating shaft. Electro-hydraulic push rods 4 are respectively arranged at the upper ends of the bracket 1. The lower ends of the telescopic ends of the electro-hydraulic push rods 4 are fixedly connected to the sliders 2. Support blocks 5 are respectively arranged on the lower sides of the front and rear ends of the bracket 1. A lower pressing die 6 is rotatably connected between the two support blocks 5 through a second rotating shaft. A motor 7 is arranged at the rear end of the bracket 1. The front end of the output shaft of the motor 7 is fixedly connected to the second rotating shaft at the rear end of the support block 5. Move the steel plate to between the upper pressing die 3 and the lower pressing die 6. Start the electro-hydraulic push rod 4. The telescopic end of the electro-hydraulic push rod 4 pushes the slider 2 downward. Under the support of the lower pressing die 6, apply pressure to the steel plate through the upper pressing die 3. At the same time, start the motor 7. The output shaft of the motor 7 drives the lower pressing die 6 to rotate. Utilize the frictional force between the steel plate, the upper pressing die 3 and the lower pressing die 6 to make the upper pressing die 3 and the lower pressing die 6 rotate relatively, driving the steel plate to move leftward, and at the same time press the steel plate into shape. Feeding support plates 8 are respectively arranged at the right end of the bracket 1, providing support for the setting of the feeding mechanism 9. A single-chip microcomputer 10 is arranged on the front surface of the front feeding support plate 8. The input end of the single-chip microcomputer 10 is electrically connected to an external power supply, controlling the start and stop of the whole device. The input ends of the electro-hydraulic push rod 4 and the motor 7 are both electrically connected to the output end of the single-chip microcomputer 10;

[0023] Loading mechanism 9: It is arranged between two loading support plates 8. The loading mechanism 9 includes loading rollers 91. The loading rollers 91 are respectively rotatably connected between the two loading support plates 8 through the third rotating shaft. The loading rollers 91 are horizontally and equally spaced to push the steel plates. Through the relative rotation between the steel plates and the loading rollers 91, it is convenient to move the steel plates to the profiling position. The loading mechanism 9 further includes a screw 92, an adjusting plate 93 and a positioning column 94. The screw 92 is respectively rotatably connected between the two loading support plates 8. An adjusting plate 93 is respectively threadedly connected between the two screws 92. The thread directions at the front and rear ends of the screw 92 are opposite. Positioning columns 94 are respectively arranged on the upper surface of the adjusting plate 93. The positioning columns 94 are respectively located between two adjacent loading rollers 91. When the screw 92 rotates, since one adjusting plate 93 is simultaneously threadedly connected to the two screws 92 and the thread directions at the front and rear ends of the screw 92 are opposite, while restricting the rotation of the adjusting plate 93, the two adjusting plates 93 are made to approach each other until the positioning columns 94 are all in contact with the steel plates, and the front and rear positions of the steel plates are restricted by the positioning columns 94 to prevent the deviation of the loading position of the steel plates. The loading mechanism 9 further includes a driving motor 95. The driving motor 95 is respectively arranged on the surface of the rear loading support plate 8. The front end of the output shaft of the driving motor 95 is fixedly connected to the screw 92. The input end of the driving motor 95 is electrically connected to the output end of the single-chip microcomputer 10 to provide power for the rotation of the screw 92. The positioning column 94 includes a positioning support column 941. The positioning support columns 941 are respectively arranged on the upper surface of the adjusting plate 93. The positioning support columns 941 are respectively located between two adjacent loading rollers 91 to restrict the front and rear positions of the steel plates. The positioning column 94 further includes an elastic rubber pad 942 and a circular ring 943. The elastic rubber pads 942 are respectively rotatably connected to the outer arc surface of the positioning support column 941 through bearings. Circular rings 943 are arranged on the outer arc surfaces of the elastic rubber pads 942. Through the relative rotation between the circular rings 943 and the steel plates, the friction force received during the movement of the steel plates is reduced. The positioning column 94 further includes a contact sensor 944. The contact sensors 944 are respectively arranged in the middle of the outer arc surface of the positioning support column 941. The output end of the contact sensor 944 is electrically connected to the input end of the single-chip microcomputer 10. After the circular ring 943 is in contact with the steel plate, the steel plate exerts a reaction force on the circular ring 943, causing the elastic rubber pad 942 to deform and contact the detection end of the contact sensor 944. The contact sensor 944 sends a signal to the single-chip microcomputer 10. By whether the contact sensor 944 sends a signal to the single-chip microcomputer 10, it is judged whether the circular ring 943 is accurately in contact with the steel plate to ensure the accuracy of the positioning of the steel plate.

[0024] The working principle of a sheet metal press provided by the present utility model is as follows: During the production of a steel structure pigsty, the steel sheet used in the production of the steel structure pigsty is placed on the surface of the loading roller 91. The driving motor 95 is started through the single-chip microcomputer 10. The output shaft of the driving motor 95 drives the screw 92 to rotate. Since an adjusting plate 93 is simultaneously threadedly connected to the two screws 92, and the thread directions at the front and rear ends of the screw 92 are opposite, while restricting the rotation of the adjusting plate 93, the two adjusting plates 93 are made to approach each other until the rings 943 are all in contact with the steel sheet. The front and rear positions of the steel sheet are restricted through the rings 943 to prevent the offset of the loading position of the steel sheet. When the rings 943 are in contact with the steel sheet, the steel sheet exerts a reaction force on the rings 943, causing the elastic rubber pad 942 to deform and contact the detection end of the contact sensor 944. The contact sensor 944 sends a signal to the single-chip microcomputer 10. By whether the contact sensor 944 sends a signal to the single-chip microcomputer 10, it is judged whether the rings 943 are accurately in contact with the steel sheet to ensure the accuracy of the positioning of the steel sheet. After the positioning is completed, the steel sheet is pushed. Through the relative rotation of the steel sheet and the loading roller 91, and the relative rotation of the rings 943 and the steel sheet, it is convenient to move the steel sheet between the upper pressing die 3 and the lower pressing die 6. Then, the electro-hydraulic push rod 4 is started. The telescopic end of the electro-hydraulic push rod 4 pushes the slider 2 downward. Under the support of the lower pressing die 6, pressure is exerted on the steel sheet through the upper pressing die 3. At the same time, the motor 7 is started. The output shaft of the motor 7 drives the lower pressing die 6 to rotate. By using the frictional force between the steel sheet, the upper pressing die 3 and the lower pressing die 6, the upper pressing die 3 and the lower pressing die 6 rotate relative to each other, driving the steel sheet to move leftward, and at the same time pressing the steel sheet into shape.

[0025] It should be noted that in the above embodiments, the single-chip microcomputer 10 disclosed can be a single-chip microcomputer of the AT89C4051 model. The electro-hydraulic push rod 4, the motor 7, the driving motor 95, and the contact sensor 944 can be freely configured according to the actual application scenario. The electro-hydraulic push rod 4 can be an electric hydraulic push rod of the DYTZ-C model. The motor 7 can be a motor of the 5IK40RGU-CF model. The driving motor 95 can be a stepping motor of the 3M57-42A model. The contact sensor 944 can be a contact sensor of the M109-RM model. The single-chip microcomputer 10 controls the electro-hydraulic push rod 4, the motor 7, the driving motor 95, and the contact sensor 944 to work using the commonly used methods in the existing technology.
