Provided is a roller laser texturing processing equipment and its processing method, comprising the following steps: dividing the processing area, determining the distribution scheme: obtaining a distribution scheme of end-to-end, unordered and uniform texturing lattice according to said roller processing unit parameters and morphological parameters; determining the output signal: the laser output position signal, beam energy regulation signal and deflection signal of one-dimensional beam deflection unit are obtained through the information processing module; performing roller laser texturing processing: said laser output position signal is used to control the light source module to emit the laser; said beam energy regulation signal and deflection signal of one-dimensional beam deflection unit are input into the laser terminal output module, respectively, to generate an unordered laser lattice, each laser terminal output module is used to process a roller processing unit. The present invention can guarantee the unordered degree of the texturing points and the uniformity of the morphology distribution at the same time, the surface consistency of the produced cold-rolled plate is better in the subsequent coating treatment.

The assembly and welding mill for production of pipes includes a tubular billet feed device with a roller table having a longitudinal axis and passing through the assembly and welding stand with radial hold-down roller beams intended for reduction of a tubular billet that travels along the roller table and a longitudinally oriented guide knife, a carriage with rollers enabling rotation of the rollers on the inner surface of the tubular billet being moved through the assembly and welding stand. On the supporting elements of assembly and welding stand there is a laser welding head or a laser-arc hybrid welding head that can travel in transverse and vertical directions and around longitudinal axis. The carriage is rigidly connected with the supporting elements of the assembly and welding stand through a vertically oriented and longitudinally directed connecting knife. The guide knife is intended for tubular billet positioning through opening of edges at 12 o'clock position and is mounted on the supporting elements of the assembly and welding stand configured to enable vertical travel and fixation. On the carriage, there is a hold-down roller facing upwards that can travel in vertical direction to act on the edges of tubular billet from the inner side, while one of the roller beams is installed vertically that can act on the tubular billet edges from the outer side. Technical result: application of a root weld with laser technologies with guaranteed alignment of tubular billet edges regardless of size.

A method of manufacturing a cylindrical cargo container includes: providing a plurality of rigid panels together formable into a cylindrical shell; forming a first semi-cylindrical shell from a first set of the panels; forming a second semi-cylindrical shell from a second set of the panels; forming the cylindrical shell from the first semi-cylindrical shell and the second semi-cylindrical shell; forming a collar conformably encircling the cylindrical shell; constricting the collar to compress joints formed at abutting edges of pairs of adjacent panels; rolling the cylindrical shell and collar to bring respective joints of pairs of panels to a lower position, and welding an inside seam of the joint when at the lower position; removing the collar from the cylindrical shell; and rolling the cylindrical shell to bring respective joints of pairs of panels to an upper position, and welding an outside of the joint when at the upper position.

A pipe clamping apparatus of a pipe processing machine includes first and second slide rails on inner and outer end surfaces of the clamping apparatus, a turntable with slot openings, first and second rotating rings with a gear rack, plural linkage modules and plural clamping components. A rod of the pneumatic cylinder is fixed to the inner end surface; the pneumatic cylinder has a rack engaged with the gear rack and is fixed to a block having an oblique slot and a rail slot; and the clamping component has a claw, a slider passing through the slot opening and oblique slot, and a rail slot. Air drives the pneumatic cylinder to move, while the rack is driving the first or second rotating rings to move the opposite pneumatic cylinder in an opposite direction, and the slider slides in the oblique slot to drive the claw to clamp the pipe.

The axle welder can be easily configured and adjusted to accommodate axle assemblies of varying axle shaft lengths, hub styles (“straight” and “drop axle”) and lug bolt configurations. The axle welder uses a sliding carriage that slides along the support frame at one end of the welder to accommodate differing shaft lengths. The axle welder also includes a pair of pivoting hub lifts that accommodate both straight and drop axle style axle hubs using modular mounting plates. Modular mounting plates (“hub adaptors”) fitted to the hub lifts accommodate hub assemblies with differing lug bolt patterns. The axle welder is built on a rectangular frame that supports a pair of weld units and articulated electrode arms. The axle welder also includes a pair axle supports for carrying the axle shafts within the support frame. A shaft drive pivotally mounted to the support frame lowers to engage and rotate the axle shaft and hub assemblies in unison during the welding process.

A self-propelled welding carriage has a body supported by a wheeled suspension having a plurality of wheels including a carriage guide wheel having a tapered rim sized and shaped to roll in conforming contact with a carriage guiding seam of a workpiece, restricting lateral movement of the welding carriage for alignment with the carriage guiding seam. Welding equipment is mounted to the body, and has a welding torch for welding an unwelded seam of the workpiece. The welding torch is mounted to the body relative to the carriage guide wheel for disposition of a welding torch tip of the welding torch in alignment with the unwelded seam of the workpiece to weld the unwelded seam when the welding carriage moves with the carriage guide wheel rolling in the carriage guiding seam. The welding carriage has a motor coupled to drive the carriage guide wheel to propel the welding carriage.

A hollow glass body comprises a cylindrical main body portion having a first inside diameter, and a first end opening and a second end opening on opposite ends of the hollow glass body. The hollow glass body has a second inside diameter at the second end opening. The second inside diameter is smaller than the first inside diameter. A difference between the first inside diameter and the second inside diameter is at most 100 μm.
