Description

Technical Field

[0001] The utility model relates to the technical field of large hot forging shaft cooling, in particular to a multi-directional spraying and rapid cooling device for large hot forging shaft parts. Background Technique

[0002] Large hot forging shaft parts usually refer to large shaft parts used in the fields of engineering machinery, ships, wind turbines, etc. They often need to be processed and formed through hot forging processes. These parts usually have complex shapes and high strength requirements. Therefore, the hot forging process can improve the density and mechanical properties of their materials, ensuring good durability and reliability during use. After forging, large hot forging shaft parts usually need to be cooled to ensure the stability of their internal structure and the optimization of mechanical properties.

[0003] The existing Chinese patent with the publication number of CN102615241B discloses a multi-directional spraying and rapid cooling device for large hot forging shaft parts, including front and rear brackets for placing large hot forging shaft parts. It is characterized in that the front and rear brackets for placing large hot forging shaft parts are arranged on the base at equal distances and in parallel. On the outer sides of the front and rear brackets for placing large hot forging shaft parts, vertical water spray pipes at the ends of large hot forging shaft parts are arranged, and axial inclined air blowers are arranged on the outer sides of the vertical water spray pipes at the ends of large hot forging shaft parts; on the left and right ends of the base, vertical water spray pipes perpendicular to the axial side surfaces of large hot forging shaft parts are provided, and outer side inclined air blowers of the shafts of large hot forging shaft parts are installed on the outer sides of the vertical water spray pipes perpendicular to the axial side surfaces of large hot forging shaft parts. This multi-directional spraying and rapid cooling device for large hot forging shaft parts has a simple structure and low energy consumption because it does not use a rotating table; because it integrates air cooling and water cooling and cools from multiple directions in rotation, the cooling of large hot forging shaft parts is uniform and fast.

[0004] In view of the above related technologies, the inclined air blower blows and scatters the water sprayed by the water spray pipe.

[0025] A hollow bent bar 148 is installed between the bottom end of the top plate 141 and the top end of the base 11, and there are multiple groups of the hollow bent bars 148. The multiple groups of hollow bent bars 148 are evenly arranged between the two sides of the top end of the base 11. Water holes 146 are opened at the bottom end of the top plate 141, and air inlet holes 147 are penetrated through the bottom end of the air inlet holes 147. The water pipe 145 is arranged in an S shape inside the plate groove 142.

[0026] A spray head 1482 is installed inside the hollow bent bar 148 at the bottom end of the air inlet hole 147, and an air outlet hole 1481 is installed inside the hollow bent bar 148 at the bottom end of the water hole 146. The air outlet hole 1481 and the spray head 1482 are sequentially arranged inside the hollow bent bar 148.

[0027] In this embodiment: The hot forging shaft parts are placed on the top end of the load-bearing member 13. The air connection head 143 and the water connection head 144 are respectively externally connected to a cold air blower and a cold water pipe (existing equipment). The cooling water is discharged into the inside of the water pipe 145 through the water connection head 144, the cooling air is discharged into the inside of the plate groove 142 through the air connection head 143. The cooling water is discharged into the inside of the hollow bent bar 148 through the air inlet hole 147 and sprayed out by the spray head 1482. The cooling air is discharged into the inside of the hollow bent bar 148 through the water hole 146 and discharged through the air outlet hole 1481, so as to cool the outer surface of the hot forging shaft parts in multiple directions.

[0028] Embodiment Two: Please refer to Figure 2 and Figure 3 , the load-bearing member 13 includes a lower pressing plate 131 and a top groove 132 opened on one side of the top end of the lower pressing plate 131. A slot 133 is opened on the top end of the lower pressing plate 131 and on one side of the top groove 132. The hot forging shaft parts are placed on the top end of the lower pressing plate 131. The provided top groove 132 and the slot 133 limit the position of the hot forging shaft parts. The cooling water in the lower pressing groove 111 can flow to the bottom end surface of the hot forging shaft parts through the slot 133, and the cooling water is used to cool the bottom end of the hot forging shaft parts.

[0029] Inner pressing strips 135 are installed on both sides of the lower pressing plate 131, and a support bent bar 134 is installed inside the slot 133 and between the lower pressing plates 131 for supporting one end of the hot forging shaft parts.
