Spiral forming methods can be used to join edges of a rolled material along a spiral joint to form conical and / or cylindrical structures. Alignment of the edges of the rolled material can be controlled in a wrapping direction as the material is being joined along the spiral joint to form the structure. By controlling alignment of the edges of the material as the edges of the material are being joined, small corrections can be made over the course of forming the structure facilitating control over geometric tolerances of the resulting spiral formed structure.

This invention relates to a locking device for the connection between a reel and the end of a pipe in the roll-type laying of subsea pipelines. An annular groove is formed at the connection between the spherical and conical shapes of the initial end. A central hole and a conical hole are sequentially arranged along the pipe's axial direction from front to back inside the initial end. After a conical fixing block is welded to the end of the axial pulling cable, the axial pulling cable is passed through the central hole of the initial end, causing the conical fixing block to engage with the conical hole inside the initial end. Left and right clamps are located on opposite sides of the initial end and are engaged with the annular groove of the initial end, with the left and right clamps being securely connected. A fixing arm is connected to the end of the right clamp, and a fixing disc is securely connected to the end of the fixing arm. A lifting ring is connected to the end face of the fixing arm. This invention enables the connection and fixation of the pipe end to the reel during the roll-up process, ensuring a firm fixation, convenient operation, and facilitating subsea pipeline laying operations, thus improving work efficiency.

This application belongs to the technical field of synthetic diamond manufacturing equipment, specifically disclosing a pressurizing device for a six-sided press, comprising: a cage, the interior of which is provided with a regular hexahedral pressure chamber, each with a conical positioning countersunk hole on its inner wall; eight secondary anvils forming a regular hexahedral composite, the outer wall of which is provided with a frustum corresponding to the conical positioning countersunk holes; and an octahedral pressure chamber inside the regular hexahedral composite. The conical positioning countersunk holes and the conical surfaces of the frustums cooperate to uniformly decompose the concentrated load applied by the external pressurizing hammer into normal clamping force and radial constraint force. This ensures that under ultra-high pressure conditions of tens of GPa, the secondary anvil can only move centripetally along its axial direction, and cannot undergo radial slippage or torsion. This reduces the risk of stress concentration and anvil breakage caused by anvil surface misalignment, ensuring the geometric stability and reusability of the secondary pressurizing device under extreme conditions.
