[0002] Automotive sheet refers to the thin steel plate used in automobile manufacturing. It has the characteristics of thin thickness, high strength and good corrosion resistance. It is widely used in the field of automobile manufacturing. Automotive sheet has good toughness and weldability, which can not only ensure the overall structure of the car body is firm, safe and reliable, but also realize lightweight and efficient automobile manufacturing. Automotive sheet generates high pressure through the hydraulic system and acts on the mold to press the metal sheet into the required shape under the shape of the mold. The hydraulic press has high forming accuracy and strong forming ability, and can process thin plates of different sizes and shapes to meet the complex needs of the automotive industry for body parts.

[0026] Example

[0027] Reference Figure 1-Figure 4 , which is an embodiment of the utility model, provides an automobile sheet metal forming hydraulic press, comprising: a hydraulic unit 100 and a limit unit 200;

[0028] The hydraulic unit 100 includes a bottom plate 101 and a plurality of support rods 102 fixedly connected to the top of the bottom plate 101. The tops of the plurality of support rods 102 are commonly fixedly connected to a support plate 103. A hydraulic cylinder 105 is fixedly installed on the top of the support plate 103. The piston rod of the hydraulic cylinder 105 penetrates downwardly through the support plate 103 and is fixedly connected to an upper pressing plate 106. A lower pressing plate 107 is fixedly connected to the top of the bottom plate 101. The hydraulic pump drives the hydraulic cylinder 105 to operate through a hydraulic pipe. The thin plate is placed directly above the lower pressing plate 107. The upper pressing plate 106 is lowered by the hydraulic cylinder 105, so that the upper pressing plate 106 cooperates with the lower pressing plate 107 to apply pressure to the thin plate to shape the thin plate into an automobile thin plate.

[0029] The limiting unit 200 includes a slide groove 201 provided on the side of the bottom plate 101, two L-shaped plates 202 are slidably arranged on the inner side of the slide groove 201, a fixed plate 203 is fixedly connected to the side of the bottom plate 101, a bidirectional screw rod 204 is rotatably connected to the side of the fixed plate 203, two threads in opposite directions are provided on the rod surface of the bidirectional screw rod 204, the bidirectional screw rod 204 is respectively threadedly connected to the two L-shaped plates 202, a plurality of rollers 205 are rotatably connected to the top of the L-shaped plate 202, a concave plate 206 is fixedly installed on the top of the bottom plate 101, an adjusting rod 207 is threadedly connected to the side of the concave plate 206, the end of the adjusting rod 207 is rotatably connected to the limiting plate 208, the bottom of the limiting plate 208 and the concave surface of the concave plate 206 are mutually fitted, the limiting plate 208 is L-shaped, and a sponge pad 214 is fixedly connected to the inner wall of the limiting plate 208;

[0030] When placing a thin plate, by rotating the bidirectional screw rod 204, the two L-shaped plates 202 can be moved closer to or away from each other along the slide groove 201, thereby adapting the two L-shaped plates 202 to thin plates of different sizes. When placing a thin plate, the two sides of the thin plate are respectively in contact with the multiple rollers 205 on the top of the two L-shaped plates 202. The rollers 205 can limit the thin plate while also facilitating the workers to quickly place the thin plate. By rotating the adjusting rod 207, the limiting plate 208 can slide on the upper surface of the concave plate 206. The limiting plate 208 can limit the side of the thin plate. The sponge pad 214 can be used to protect the thin plate when the worker pushes it to contact the limiting plate 208. The three sides of the thin plate are limited to ensure that the thin plate is accurately located directly above the lower pressing plate 107 to ensure that it is processed into a qualified automotive thin plate. The limiting plate 208 can be adjusted according to thin plates of different sizes by adjusting the rod 207 to improve the practicability of the equipment.

[0031] In addition, a limiting groove 209 is provided at the top of the bottom plate 101, and a spring 210 is fixedly connected to the inner wall of the limiting groove 209, and a T-shaped plate 211 is fixedly connected to the end of the spring 210, and a rotating plate 212 is movably inserted into the top of the T-shaped plate 211, and a handle is fixedly connected to the top of the rotating plate 212, and a plurality of rollers 213 are rotatably connected to the bottom of the rotating plate 212, and the part where the rotating plate 212 is connected to the rollers 213 is designed to be telescopic, and the rotating plate 212 is composed of a straight rod and a telescopic horizontal plate, and the rotating plate 212 is vertically parallel to the T-shaped plate 211, and a torsion spring 215 is sleeved on the side of the straight rod, and the two ends of the torsion spring 215 are respectively fixedly connected to the opposite surfaces of the telescopic horizontal plate and the T-shaped plate 211, and the thin plate can be tightly fitted to the T-shaped plate 211 and the limiting plate 208 through the T-shaped plate 211 and the spring 210;

[0032] By pushing the T-shaped plate 211 through the spring 210, the thin plate can be clamped between the T-shaped plate 211 and the limiting plate 208, thereby further ensuring that the thin plate will not be deflected by the pressure during the shaping process, so as to ensure the aesthetics of the shaping. By rotating the rotating plate 212, the roller 213 rolls on the surface of the thin plate to flatten the thin plate and make it fit tightly to the upper surface of the lower pressing plate 107, so as to prevent the thin plate from warping.

[0033] The rotating plate 212 is composed of a straight rod and a telescopic cross plate, and the telescopic cross plate can extend and shorten the length of the rotating plate 212 to facilitate the use of thin plates of different sizes. The top of the T-plate 211 is provided with a groove that fits the straight rod, so that the straight rod can slide up and down in the groove. After the thin plate is placed on the lower pressure plate 107, the handle is pulled upward to make the lowest point of the roller 213 higher than the upper surface of the thin plate. Then, the rotating plate 212 is manually rotated to make the roller 213 roll on the upper surface of the thin plate, and the handle is manually pressed downward to make the roller 213 apply a downward force to the thin plate so that there is no gap between the thin plate and the lower pressure plate 107. When the thin plate is in contact with the upper surface of the lower pressure plate 107, the handle is released, and the two ends of the torsion spring 215 are respectively fixedly connected to the opposite surfaces of the telescopic cross plate and the T-plate 211, so that the rotating plate 212 can be automatically reset by the torsion spring 215 after use to prevent the rotating plate 212 from hindering the upper pressure plate 106 from descending.

[0034] During use, according to the actual size of the automobile thin plate processing, the distance between the two L-shaped plates 202 is adjusted by rotating the bidirectional screw rod 204, and the limiting plate 208 can be made to slide on the upper surface of the concave plate 206 by rotating the adjusting rod 207. After the adjustment is completed, the worker pushes the thin plate in front of the two L-shaped plates 202, and the two sides of the thin plate are respectively in contact with the multiple rollers 205 on the top of the two L-shaped plates 202. Then, the side of the thin plate is blocked by the limiting plate 208, and then the T-shaped plate 211 is pulled, and the T-shaped plate 211 is pushed by the spring 210, so that the thin plate can be clamped between the T-shaped plate 211 and the limiting plate 208, thereby adjusting the four sides of the thin plate. The upper plate 106 is lowered by the hydraulic cylinder 105, so that the upper plate 106 applies pressure to the plate, and cooperates with the lower plate 107 to shape the plate into a car plate. After shaping, the upper plate 106 is driven up by the hydraulic cylinder 105, and then the car plate can be taken out.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
