The invention discloses a craniocerebral drainage tube submerged implanting device, which comprises an outer cone and a cone core that cooperate with each other, the outer cone is provided with a groove extending from the front end to the middle and rear, the groove and the cone core Cooperate to form a half-wrap structure on the side of the front section of the cone core. The front end of the outer cone and the cone core cooperate together to form a tip. The outer cone is provided with a wing plate on the edge of the groove near the front end. When the cone core withdraws After detaching from the groove, the wing plate is used to cooperate with the enlarged groove with reduced diameter to engage the enlarged end of the drainage tube. When the outer cone is withdrawn, it can effectively and reliably pull the drainage tube back along the subcutaneous tunnel to achieve the purpose of stealth. The tunnel is formed at one time, and the drainage tube sneaking is completed at one time. One end of the semi-wrapped structure formed by the cone core and the outer cone, the size of the incision is similar to the diameter of the submerged tunnel constructed, and the distance and direction of the tunnel can be precisely controlled, avoiding scalp peeling caused by the use of vascular clamps to establish drainage tubes for submersion The problem of not being able to actually create a subcutaneous tunnel.

The invention discloses a wave-proof plate for a liquid tank, which comprises a wave-proof plate matching the cross-sectional shape of the liquid tank and an impact control device. The surface of the wave-proof plate is corrugated, and the plate is opened There are air holes on the upper end, side holes on both sides, and liquid holes on the bottom of the plate body. Ribs are provided on the edge of the opening of the liquid hole and the side hole to solve the problem of stress concentration at the opening position. The invention adds side holes on both sides of the anti-wave plate to prevent the gas generated in the two cavities of the tank body from being unable to communicate with each other when the tank body rolls over, causing pressure imbalance and causing deformation or even damage to the tank body and the anti-wave plate. At the same time, the corrugated The anti-wave plate body can buffer the stress caused by the sloshing of the liquid, and the position of the opening at the bottom is moved up, which lengthens the length of the bottom weld seam, effectively improves the strength of the anti-wave plate, and also solves the problem at the buffer port on the anti-wave plate. The problem of stress concentration effectively prevents the tearing of the anti-wave board and improves the service life of the anti-wave board.

The invention discloses a composite molding process of a large-size titanium-made end socket. The composite molding process comprises the following steps of: 1, molding a bulge part of the end socket by machining in a multimode and multi-pass hot stamping manner, to be specific, carrying out hot stamping on a machined blank arranged in a stamping die for a plurality of times to obtain a semifinished product of the end socket by adopting a punching machine from front to rear according to a predesigned structure and size of the bulge part of the large-size titanium-made end socket; 2, carrying out side shearing, to be specific, carrying out side shearing on the semifinished product of the end socket; and 3, molding a straight side part and a corner transition part of the end socket by cold spinning , to be specific, carrying out cold spinning on an upper port of the semifinished product of the end socket which is subjected to side shearing in the step 2 to obtain a molded end socket finished-product by adopting spinning equipment according to predesigned structures and sizes of the straight side part and the corner transition part of the large-size titanium-made end socket. The composite molding process disclosed by the invention is simple in steps, reasonable in design, simple and convenient to operate and good in using effect; and both the mechanical property and the chemical components of the molded end socket can meet relative standard requirements.
