Description

LG steel cylinder cap bore reducing machine

The utility model relates to a kind of end socket reducing of end socket reducing processing equipment, especially cylinder for liquefied gas of pressure vessel.

When existing steel cylinder seal head necking machine is worked, be that workpiece is enclosed within on the large diameter mold, by the mold driven rotary, roller radial compression workpiece makes it to produce plastic deformation, and roller is unpowered, and by workpiece frictionally driven rotary, cam drive is adopted in feeding.Because the mold diameter is bigger, workpiece can not be made big strain during work, to relax the increase of internal stress, so workpiece if in advance annealing in process then to be prone to workpiece working position internal stress in the process excessive and crack and scrap, adopt machine driving also may cause accidentalia that the workpiece cracking is scrapped, roller is unpowered, and the linear velocity synchronism between workpiece is relatively poor, and workpiece machining surface is second-rate.

The purpose of this utility model is a kind of new steel cylinder seal head necking machine of design, ftractures and scraps to avoid workpiece to produce bigger internal stress in process, in addition, also improves the machined surface quality of workpiece.

Now elaborating the utility model in conjunction with the accompanying drawings is how to realize above-mentioned purpose:

Accompanying drawing 1 is a front view of the present utility model, 1 is fuselage, the 2nd among the figure, workpiece, the 3rd, and internal trolley, the 4th, outer roller, the 5th, planker, the 6th, panel, the 7th, oil cylinder, the 8th, axle, the 9th, gear I, the 10th, gear II, the 11st, shaft coupling, the 12nd, axle, the 13rd, holder, accompanying drawing 2 are vertical views of the present utility model, 14 is roller seats, the 15th among the figure, roller, the 16th, sliding seat, the 17th, radial support roller, the 18th, preceding supporting roller.

Shown in accompanying drawing 1,2, the utility model is by fuselage 1, two vertical shafts that are parallel to each other 8,12, be located at respectively outer roller 4 and the internal trolley 3 of vertical shaft 8,12 upper ends, be located at two vertical shafts 8,12 lower ends and intermeshing two

gears

9,10, be located at 17, two the axially mounting rollers 15 of two workpiece radial support rollers on the fuselage surface, two front support rollers 18 form. The vertical shaft 12 that internal trolley 3 is housed links to each other with fuselage by holder 13, and the vertical shaft that outer roller 4 is housed is located on the planker 5, and planker 5 can move along the panel 6 on the fuselage 2. Vertical shaft 12 lower ends also are provided with shaft coupling 11, and power source is come in transmission of power by shaft coupling 11. Planker 5 drives by oil cylinder 7. Because vertical shaft 8 is fixed on the planker, when making minute movement for assurance vertical shaft 8 with planker 5, gear 9 still meshes with gear 10, and the rotation of preserving fixed angle speed, and

gear

9 and 10 is the involute gear of big modulus. For adapting to the workpiece of different scales size, radial support roller 17 is located on the sliding seat 16, and sliding seat 16 can radially be regulated.

Operation principle is such: on axially mounting roller 15 and front support roller 18, radial support is realized by radial support roller and internal trolley with the location with 2 of workpiece. Oil cylinder 7 is pushed outer roller 4 to workpiece 2, and with meat roller 3 with workpiece 2 clampings. When power source drove vertical shaft 12 rotation by shaft coupling 11, therefore the gear 10 on it and gear 9 engagements, rotated vertical shaft 8, and the roller on two vertical shafts also rotates, thereby drives the workpiece rotation.

Technical characterstic of the present utility model and result of use:

1, adopts the scheme of inside and outside roller holding workpiece owing to the cancellation mold, and internal trolley designs more much smallerly than mold diameter, therefore, add man-hour, workpiece can be done the increase that bigger strain cushions internal stress, thereby avoided the workpiece working position seminess to occur, and do not needed to carry out earlier annealing in process before the workpiece processing.

2, because the radial feed of outer roller is to adopt hydraulic drive, therefore stable drive, has eliminated the harmful effect that accidentalia caused.

3, because inside and outside roller is power wheel, drive the workpiece rotation simultaneously, the linear velocity synchronism of workpiece and roller is better, thereby has improved the quality of machined surface.
