[0026] Furthermore, both the movable clamping cylinder 201 and the fixed clamping cylinder 2 clamp the dam surface through the clamping pressure plate 203 set below, so as to prevent the dam surface from sliding during the forming process and affecting the forming shape of the arc-shaped dam surface.

[0027] A clamping motor 205 is fixedly connected to the surface of the clamping frame 202. A clamping screw 206 and a clamping guide rod 207 are rotatably connected to the surface of the clamping frame 202.

[0028] Furthermore, the clamping motor 205 drives the clamping slider 208 to move along the axis of the clamping screw 206 via the clamping screw 206, thereby adjusting the position of the moving clamping cylinder 201 below the clamping slider 208.

[0029] By setting up a clamping mechanism, the clamping mechanism uses the fixed clamping cylinder 2 and the base 1 to fix and clamp one end of the dam surface, thus preventing slippage and deformation of the arc surface during the dam surface forming process.

[0030] To extrude the surface of the hydraulic dam into an arc shape and maintain the smoothness of the arc shape, a forming mechanism is set up, referring to... Figures 1-2 The forming mechanism includes a forming roller 3, which performs the action of pressing the dam surface with the forming roller 3 to form an arc surface.

[0031] The molding mechanism also includes a molding screw 301, one end of which is fixedly connected to a molding pulley 302. The two molding screws 301 are symmetrically distributed around the axis of the base 1. The surfaces of the two molding pulleys 302 are connected by a belt drive. A molding motor 303 is fixedly connected to the surface of the base 1. The output shaft of the molding motor 303 is fixedly connected to one end of the molding screw 301 through a coupling.

[0032] Furthermore, the molding motor 303 drives the molding screw 301 to rotate, and the surfaces of the two molding pulleys 302 are connected by belt drive to drive the two molding screws 301 to rotate synchronously.

[0036] Furthermore, the forming cylinder 306 drives the forming roller 3 to press the dam surface along the surface of the forming groove 308 through the forming connecting block 307 to form an arc-shaped dam surface.

[0038] Working principle:

[0039] Before use, place the dam surface above the forming groove 308, with one end of the dam surface placed above the anti-slip mat 309. Drive the clamping motor 205 on the surface of the clamping frame 202. The clamping motor 205 drives the clamping slider 208 to move along the axis of the clamping guide rod 207 via the clamping screw 206. After adjusting the position of the clamping slider 208, drive the fixed clamping cylinder 2 on the surface of the clamping frame 202 and the moving clamping cylinder 201 below the clamping slider 208, respectively. This will drive the two clamping pressure plates 203 to move downwards, fixing and clamping the dam surface. The pressure sensor 204 on the surface of the clamping pressure plate 203 monitors the clamping pressure. After the dam surface is fixed and clamped, the forming screw 301 is rotated by the forming motor 303 on the surface of the base 1. The forming slider 304 on the surface of the forming screw 301 slides along the groove 305 on the surface of the base 1. The forming cylinder 306 above the forming slider 304 is rotatably connected to one end of the forming roller 3 through the forming connecting block 307. The forming pulleys 302 on the surfaces of the two forming screws 301 are connected by belt drive, which drives the two forming screws 301 to rotate synchronously, so that the two ends of the forming roller 3 move synchronously to maintain the stability of the forming roller 3. The two forming cylinders 306 simultaneously drive the forming roller 3 to slide along the surface of the forming groove 308 on the surface of the base 1, and extrude the dam surface between the forming roller 3 and the forming groove 308 into an arc shape. After the arc-shaped hydraulic dam surface is formed, the clamping mechanism is released, and the dam body slides down the surface of the forming groove 308 for easy collection.
