[0029] In the embodiment of the utility model, this case provides a high-precision steel plate forming device for flattening steel plates, including a base 100 and a hydraulic mechanism 200, and also including a first pressing die 110, a second pressing die 120 and a cold water circulation system 300. A plurality of vertical guide rods 130 are provided at the corners of the base 100, and a hydraulic mechanism 200 is provided at the upper end of the guide rod 130. The driving end of the hydraulic mechanism 200 is downwardly connected to the first pressing die 110 and drives it to move up and down along the guide rod 130. A corresponding second pressing die 120 is provided on the base 100, and the second pressing die 120 is provided with a stress groove 140. The side ends of the first pressing die 110 and the second pressing die 120 are also provided with a plurality of water inlets 150 and water outlets 160, and the water inlets 150 and the water outlets 160 are connected to the cold water circulation system 300 located on one side of the base 100, and the cold water circulation system 300 is used to quickly cool down the steel plate.

[0030] Specifically, the device can perform high-precision flattening treatment on the steel plate through the synergistic effect of the hydraulic mechanism 200 and the pressing die. Due to the drive of the hydraulic mechanism 200 and the design of the die, the uniformity of the flattening effect can be guaranteed. The device is equipped with a cold water circulation system 300, and cold water is introduced into the first pressing die 110 through the water inlet 150 and the water outlet 160 for reciprocating flow, thereby rapidly reducing the temperature of the steel plate. The rapid cooling process can effectively reduce the thermal deformation and residual stress of the steel plate, improve the molding quality, and quickly flatten. A plurality of vertical guide rods 130 are provided at the corners of the base 100 of the device, and the driving end of the hydraulic mechanism 200 is downwardly connected to the first pressing die 110. Such a design can ensure the stability and high compactness of the device structure, and reduce the volume and floor space of the device. The second pressing die 120 is equipped with a stress groove 140, and the device can also perform stress treatment on the steel plate. The design of the stress groove 140 can help the steel plate release stress and improve the material properties and overall strength of the steel plate.

[0031] In another embodiment of the utility model, the hydraulic mechanism 200 includes a support seat 210, a hydraulic cylinder 220, and a piston rod 230. The support seat 210 is installed at the upper end of the guide rod 130. The hydraulic cylinder 220 is placed at the upper end of the support seat 210. The driving end of the hydraulic cylinder 220 is connected to the piston rod 230 downward, and the other end of the piston rod 230 is connected to the first pressing mold 110. The hydraulic cylinder 220 drives the first pressing mold 110 to move up and down through the piston rod 230. Specifically, the device uses the hydraulic mechanism 200 to drive the first pressing mold 110 to move up and down, and uses the hydraulic cylinder 220 to control the movement of the piston rod 230, so as to achieve accurate flattening of the steel plate. The stability and precise control of the hydraulic mechanism 200 can ensure the high precision of steel plate forming. The support seat 210 is used in the device to install the hydraulic cylinder 220 on the upper end of the guide rod 130. The stability and rigidity of the device can be enhanced by connecting the support seat 210 with the guide rod 130. The stable device structure can provide a more reliable forming effect.

[0032] In another embodiment of the utility model, the stress grooves 140 are arranged crosswise at 90 degrees on the surface of the second pressing mold 120. Specifically, the stress at a certain point in the steel plate is reduced due to the release of energy. The stress groove 140 refers to a processing method of cutting grooves on aluminum parts. The stress groove 140 is mainly used as a measure to reduce or eliminate casting stress. The stress grooves 140 are arranged crosswise at 90 degrees, so that the stress grooves 140 have a more appropriate stress elimination capability.

[0033] In another embodiment of the utility model, the cold water circulation system 300 includes a cooling pump 310, a cooling pipe 320 and a cooling tower 330. The cooling tower 330 is located on one side of the base 100. The cooling pipe 320 is divided into an inlet pipe 340 and an outlet pipe 350. The input end and the output end of the cooling tower 330 are correspondingly connected to the inlet pipe 340 and the outlet pipe 350, and the other ends of the two are correspondingly connected to the water inlet 150 and the water outlet 160. The cooling pump 310 is arranged at the middle end of the inlet pipe 340 and the outlet pipe 350 to promote the flow of cooling water. Specifically, when the steel plate is heated and processed into a rough embryo, it is placed on the base 100. The first pressing mold 110 is pressed into the second pressing mold 120 under the drive of the hydraulic mechanism 200 to press the steel plate. The cooling tower 330 supplies cooling water through the water inlet pipe 340, and enters the first pressing mold 110 and the second pressing mold 120 from the water inlet 150. The cooling water forms a heat exchange with the heated steel plate, and the heat is absorbed by the cooling water, so that the temperature of the cooling water increases. The cooling pump 310 flows the heated cooling water through the water outlet 160 to the water outlet pipe 350, and then flows into the cooling tower 330. After the cooling tower 330 cools down the heated cooling water again, it flows into the first pressing mold 110 and the second pressing mold 120 through the water inlet pipe 340. This cycle is repeated continuously to shape and cool the steel plate.

[0034] In another embodiment of the utility model, a reinforcing rib 400 is connected between the edge end of the hydraulic cylinder 220 and the support seat 210 to enhance stability.

[0035] In another embodiment of the utility model, a protective fence (not shown) is provided on the edge of the support base 210 to prevent operators from accidentally touching it and causing accidents.

[0036] The above are only preferred embodiments of the present invention and are not intended to limit the present invention.
