Technical Field

[0001] This utility model relates to the field of sealing ring processing technology, and more specifically, to a forging device for a high-pressure hydraulic cylinder sealing ring. Background Technology

[0002] Hydraulic cylinder seals are a crucial component of hydraulic cylinders, and their quality directly affects the cylinder's sealing performance and service life. Currently, the main processing techniques for hydraulic cylinder seals include molding, injection molding, and turning. However, for some high-strength, high-wear-resistant seals, forging is required to improve their structural density and mechanical properties.

[0003] Currently, traditional forging devices are inconvenient for positioning when processing hydraulic cylinder seals, which can easily lead to forging deviations and affect quality. In addition, heating is required before placing the seals into the forging equipment, which is cumbersome and can affect forging efficiency. Therefore, it is necessary to propose a forging device for high-pressure hydraulic cylinder seals to solve the above problems. Utility Model Content

[0018] Please see Figures 1-5 This utility model provides a technical solution: a forging device for a high-pressure hydraulic cylinder seal ring, including a support structure 100 and a forging structure 200.

[0019] Please see Figures 1-4 The support structure 100 includes a forging table 110, a traction member 130, and an electric heating wire 140. Two sliding grooves 111 are provided on one side of the forging table 110. A forging zone 112 and an annular groove 114 are formed on the top surface of the forging table 110. The traction member 130 is installed on the forging table 110, and the electric heating wire 140 is installed in the annular groove 114.

[0020] The forging zone 112 is located on one side of the annular groove 114. A discharge notch 113 is provided on the forging table 110, located on one side of the forging zone 112. The discharge notch 113 facilitates the output of raw materials. Support columns 120 are symmetrically fixed at the bottom of the forging table 110, and support pads 121 are fixed at the bottom of the support columns 120.

[0021] The traction component 130 includes an electric cylinder 131 and two movable rods 132. The electric cylinder 131 is installed at the bottom of the forging table 110. The two movable rods 132 are slidably connected inside the slide groove 111. The ends of the two movable rods 132 are fixed with end plates 133. The output end of the electric cylinder 131 is fixed with the end plate 133. The top surface of the end plate 133 is fixed with a connecting plate 134. By utilizing the intermittent operation of the electric cylinder 131, the sealing ring can be conveniently heated, forged, and output, which can help improve processing efficiency.

[0022] Please see Figure 1 Figure 2 and Figure 5 The forging structure 200 includes a forging part 210 and a limiting mold base 230. The forging part 210 is installed on the top surface of the forging table 110. The output end of the forging part 210 is equipped with a forging head 220. The limiting mold base 230 is installed on the traction member 130.

[0023] The forging part 210 includes four limiting rods 211 and a hydraulic cylinder 213. The four limiting rods 211 are symmetrically fixed on the top surface of the forging table 110. A top plate 212 is fixed on the top surface of the four limiting rods 211. The hydraulic cylinder 213 is installed on the top plate 212. A movable seat 214 slides through the four limiting rods 211. The forging head 220 is installed on the movable seat 214.

The inclined inner side of the die holder 231 can facilitate the placement and positioning of the sealing ring, thereby improving the positioning accuracy, reducing the occurrence of deviations, and improving the stamping quality.

[0025] Specifically, the working principle of the forging device for the high-pressure hydraulic cylinder seal ring is as follows: During use, the seal ring is placed inside the die base 231, positioned above the annular groove 114. The seal ring is heated using an electric heating wire 140. After heating, the seal ring is moved to the forging zone 112 by the electric cylinder 131. Then, the hydraulic cylinder 213 drives the movable seat 214 and the forging head 220 downwards. The forging head 220 performs forging operations on the seal ring in the die base 231. After forging, the seal ring is moved by the electric cylinder 131 to the die base 231, positioning it at the discharge notch 113 for output. This process is repeated. This facilitates positioning during forging, reducing the possibility of deviations and improving forging quality. It also facilitates heating, forging, and output, reducing operational steps and improving forging efficiency.

[0026] It should be noted that the specific models and specifications of the electric cylinder 131, the electric heating wire 140, and the hydraulic cylinder 213 need to be selected and determined according to the actual specifications of the device. The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0027] The power supply and operating principle of the electric cylinder 131, the electric heating wire 140, and the hydraulic cylinder 213 are clear to those skilled in the art and will not be described in detail here.
