The invention discloses a safety air bag part positioning and punching forming device and a forming method thereof, and relates to the technical field of punching equipment. Comprising a forming installation part, and a flatness detection part is installed on the forming installation part and used for prompting that a blank is bent; a series connection prompting piece is mounted on the forming mounting piece; the flatness detection piece is used for conducting the series connection prompting piece; a safety switch piece is installed on the side face of the forming installation piece. A spiral driving piece is mounted on the safety switch piece; the serial prompting piece is matched with the flatness detecting piece, so that the flatness of the blank can be automatically detected when the blank is placed, and the situation that bending is not known in time during early-stage machining is avoided.

This invention relates to the field of bridge construction technology, and particularly to a steel-concrete composite beam support and its preloading construction method. The steel-concrete composite beam support includes two rows of separate side supports, which are used to symmetrically support the bottom of the side boxes on both sides of the main steel beam. Multiple rows of steel pipe columns are arranged at intervals, and each row of steel pipe columns includes multiple steel pipe columns. Adjacent steel pipe columns are connected by diagonal bracing groove steel frames. A transverse distribution beam is fixed at the top of the multiple rows of steel pipe columns, and a Bailey beam is fixed on the transverse distribution beam. A track distribution beam is set on the top of the Bailey beam, and a sliding track is set on the track distribution beam. A transport trolley slides on the sliding track. The sliding track and transport trolley realize dynamic segmented preloading, ensuring that the settlement data accurately reflects the performance of the support. The modular structure facilitates rapid assembly and shortens the construction period. The symmetrical arrangement of the separate side supports avoids load concentration in the middle, reduces local stress concentration, and results in a more uniform load distribution, making it suitable for the construction of long-span bridges.

The utility model relates to stainless steel grating plate welding technical field discloses a kind of stainless steel grating plate anti-deformation welding devices, including base, the inner wall of base is equipped with clamping mechanism, the clamping mechanism is used to clamp grid plate, the top of the clamping mechanism is equipped with support mechanism, and the support mechanism is used to support grid plate;The clamping mechanism includes fixed plate, and the fixed plate is fixedly connected in the inner wall of base upper portion.In the utility model, motor rotation drives connecting block rotation, connecting block rotation pulls connecting plate, connecting plate pulls slider to thereby drive long plate to move left and right in the outer wall of slide rail, long plate moves and pulls support arm, so that support arm drives rotation of pivot, pivot rotation makes the clamping plate of support arm top gather in the middle, so that the outer wall of clamping plate is always attached to the both sides of grid plate, prevent grid plate position deviation from leading to deformation when welding, fixed rod can adapt to grid plate of different height, improve use range.

The utility model relates to laser cladding processing technical field, concretely is a kind of laser cladding metal additive manufacturing equipment, including the connecting assembly for being connected in the wall of extension long tube spray head, multiple rollers are equipped in the circumferential direction on connecting assembly, the fan blade of coaxial setting is respectively fixedly installed on each roller, and the outer periphery of multiple rollers is used to contact the inner wall of workpiece simultaneously, and with the rotation of workpiece homodirectional rotation, to realize that fan blade rotates under the driving of roller and generates airflow.The utility model can inhibit the elastic deformation of the extension long tube spray head far end by the rotation of roller set, ensure light path transmission and spot size stability, improve cladding layer precision, quality and efficiency.Meanwhile, fan blade rotation can efficiently discharge cladding heat, slow down component aging, prolong service life, protect high-quality cladding layer formation;And fan blade rotation can also discharge excess powder and smoke, improve processing visibility and efficiency, reduce cladding layer surface roughness, improve surface quality.

The utility model discloses a lifting device and a lifting connection device. The lifting device comprises a supporting structure, the supporting structure comprises at least one supporting assembly, the supporting assembly is used for containing a base plate, each supporting assembly comprises a first base, the first base is provided with a plurality of sets of supporting units, and the supporting units are connected with the base plate; the lifting structure comprises a driving part, the output end of the driving part is provided with a steering assembly, the steering assembly is connected with at least one lifting assembly and converts rotary motion into vertical motion, and the lifting assemblies are connected with the first base so as to drive the base plate to ascend or descend. According to the utility model, the single driving piece drives the lifting assemblies through the steering assembly, so that synchronous lifting of multiple supporting points is ensured, and inclination or clamping stagnation of the substrate is avoided; the steering assembly converts the horizontal rotating motion of the driving piece into the vertical direction, and the problem that the precision of a traditional pneumatic / hydraulic system is insufficient due to pressure fluctuation is solved.
