This invention discloses a thread friction coefficient testing machine, including a test drive unit, a main base, a pad, and a detachable fixture. The fixture includes an assembly base, a clamping actuator with an anti-rotation groove, and a circumferential locking pin, the tail end of which protrudes from the base. When the threaded pair slips, the locking pin is removed and the clamping actuator is rotated from the outside, allowing the fixture, along with the internally jammed fasteners, to be removed as a whole without destructive operation. This design not only achieves non-destructive and rapid unloading of the threaded pair, but its protruding clamping end and axial adjustment hole also expand the equipment's ability to test the friction coefficient of short bolts, significantly improving the maintainability, operating efficiency, and testing applicability of the equipment.

This invention provides a direct hot-rolling composite equipment and method for seamless metal composite tubes, including a heating furnace, a first feeder, a skew rolling piercing mill, a piercing device, an intermediate feeder, an online heating device, and a three-roll skew rolling mill unit. Solid bar billets are heated in the heating furnace and then conveyed to the skew rolling piercing mill via the first feeder. The piercing device inserts a mandrel into the inner tube and delivers the mandrel, fitted with the inner tube, to the piercing position of the skew rolling piercing mill, where a mandrel is installed. The skew rolling piercing mill performs piercing rolling to obtain the outer tube, which then passes through the mandrel and wraps around the inner tube to obtain the composite tube billet. The intermediate feeder delivers the billet to the three-roll skew rolling mill unit for three-roll skew rolling composite processing. This invention utilizes skew rolling piercing equipment to produce seamless metal composite tube billets simultaneously with piercing, realizing the preparation of seamless metal composite tubes from solid bar billets on a single production line. The preparation process is simple and convenient, shortens the process flow, improves production efficiency, and reduces costs.

The application discloses a terminal detection device and method, relates to the technical field of terminal detection, and comprises a test box, a mounting plate is arranged in the test box, a plurality of test mechanisms for clamping terminals are detachably arranged on the top wall of the mounting plate, the test mechanism comprises a bearing seat, an installation cavity with an opening upward is arranged on the top of the end away from the rotating shaft of the bearing seat, a trigger piece for placing a tubular terminal is vertically and slidably arranged in the installation cavity, and a supporting piece for placing a connecting end of a circular terminal is detachably arranged above the trigger piece in the installation cavity. By arranging the installation cavity to simultaneously bear the detachable supporting piece and the trigger piece, the device can clamp and limit the circular terminal and the tubular terminal by only using different contact modes with the contact column without replacing the main bearing structure, the defect that the existing detection equipment needs to replace a complete set of clamps for different terminals is overcome, and one machine is used for multiple purposes.
