Abstract

The utility model relates to a spinning necking machine for a steel cylinder. One end of a bottom rack of the machine is provided with a mold turning plate gear box; a mold turning plate shaft which is extended from the mold turning plate gear box is fixed with an L-shaped mold turning plate; the middle of the bottom rack is provided with a spindle box, wherein, a rotary shaft line of which is mainly vertical to the shaft line of the mold turning plate; the spindle end is provided with a sandwich plate. In addition, a track on the other end of the bottom rack is provided with a swinging arm shaft seat which can move along the track; the extended shaft of the swinging arm shaft seat is fixed with a swinging arm provided with a roller shaft seat, and the roller shaft end in the roller shaft seat is fixed with a roller. As the roller moves along specific circular arc track in the spinning process, a cylinder shoulder formed after the necking forms a hemispherical shape and keeps constant all the time; in addition, as the roller and cylinder blank form rolling friction, the surface smoothness of the cylinder shoulder is better.

Description

Roller type steel cylinder hot spinning closing in machine

Technical field

The utility model relates to a kind of steel cylinder closing in machine, especially a kind of steel cylinder spinning closing-in machine.

Background technology

Understand according to the applicant, steel cylinder rollover board closing in machine is the capital equipment that existing steel cylinder closes up.When this closing in machine is worked, pre-heated bottle base is clamped on the main shaft, rotates at a high speed, then gradually shoulder is spun into approximate hemispherical for≤90 °, finishing the operation of closing up by the template rotation by motor-driven.Since in this process, be sliding friction all the time between template and the bottle base, two point defects below therefore in batch process, existing: the one, the shoulder shape changes with the wearing and tearing of template face, can't guarantee the definition that the steel seal carving machine is carved characters in the later process; The 2nd, the fineness at shoulder position is not good, and groove mark is more serious, often needs to increase the polishing operation.

Summary of the invention

The purpose of this utility model is: propose a kind ofly can guarantee shoulder shape unanimity, the good roller type steel cylinder hot spinning closing in machine of fineness.

In order to reach above purpose, an end is installed the rollover board gear-box on the underframe of roller type steel cylinder hot spinning closing in machine of the present utility model, the rollover board of fixed L shape on the rollover board axle that stretches out by the rollover board gear-box, rotation and the vertical substantially main spindle box of rollover board axis are installed in the underframe middle part, spindle end is sandwich dish, in addition, the swing arm axle bed that can move along track is housed on the track of the underframe other end, be fixed with swing arm on the projecting shaft of swing arm axle bed, the roller axle bed is housed on the swing arm, and the roller axle head in the roller axle bed is fixed with roller.

After roller type steel cylinder hot spinning closing in machine starts, at first to be similar to the manner of execution work of existing steel cylinder rollover board closing in machine, promptly will be clamped in the bottle base spinning that heating is in advance also rotated at a high speed on the main shaft and thicken preliminary closing in by L shaped rollover board, then, rollover board is return original position, and the swing arm axle bed moves along track, roller abuts on the bottle base, swing arm swing, roller moves along arc track, with the process of bottle base rolling spinning in bottleneck is drawn in.

Because roller moves along specific arc track in spinning process, the shoulder after therefore closing up is shaped as hemispherical, remains unanimity, and is rolling friction between roller and the bottle base, so the shoulder surface smoothness is better.

The specific embodiment

Embodiment one

Roller type steel cylinder hot spinning closing in machine underframe 16 left ends of present embodiment are installed rollover board gear-box 12, the rollover board 11 of fixed L shape on the rollover board axle that is stretched out by this gear-box 12.In gear-box 12, the tooth bar engagement that the wheel and rack oil cylinder 13 that is connected with the rollover board axle drives.Therefore when tooth bar moves, will order about rollover board 11 upsets under oil cylinder 13 drives.

Rotation and the vertical substantially main spindle box of rollover board axis are installed in underframe 16 middle parts, and spindle end is installed the sandwich dish 9 of clamping bottle base 10.When main shaft rotates, will drive bottle base 10 by sandwich dish 9 and rotate synchronously.When rollover board 11 upsets, pre-heated bottle base 10 thickens preliminary closing in (referring to Fig. 3) in spinning process.

The swing arm axle bed 5 that can move along track is housed on the right-hand member track of underframe 16, be fixed with swing arm 7 on the projecting shaft of this swing arm axle bed 5, roller axle bed 17 is housed on the swing arm 7, and the roller axle head in the roller axle bed 17 is fixed with roller 8, and the edge of roller 8 is "〉" shape.In order to make moving reliably freely of roller 8, swing arm axle bed 5 is hinged with the piston rod that is fixed on the roller front and back cylinder displacement 15 on the underframe 16, the projecting shaft of swing arm axle bed 5 and gear 3 are connected, this gear 3 and tooth bar 2 engagements, this tooth bar 2 is connected with the piston rod that is installed in 5 times oil cylinders 4 of swing arm axle bed.

Like this, when 15 actions of cylinder displacement before and after the roller, swing arm axle bed 5 will be with roller 8 near the preliminary bottle base 10 that closes up, when oil cylinder 4 actions, to drive swing arm 7 by the projecting shaft of swing arm axle bed 5 rotates, because the projecting shaft of swing arm axle bed 5 and roller shaft be or not same plane, so roller axis and main-shaft axis be angle, makes roller 8 be in desirable secondary spinning position (referring to Fig. 4).When main shaft drove bottle base 10 high speed rotating of preliminary closing in, roller 8 was in swing arm 7 rotating process, by rolling friction, finish secondary finishing spinning, guarantee that the shoulder that is spun to is spherical in shape, and present good fineness, thereby lay a good foundation for follow-up system steel seal.In addition, the shape of roller 8 just in time can form the bottle neck that needs machining screw in the secondary spinning process.

In addition to the implementation, the utility model can also have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
