Abstract
A rolling rib head relates to a die head used for processing rib strips on a thin plate face. The rolling rib head comprises a casing, a flexible device, a ball bowl, hard beads for rolling rib, and a plurality of small steel balls, wherein the casing is barrel-shaped; the ball bowl is arranged in the casing, and the cross section shape thereof is less than that of the casing, so that the ball bowl can axially moves in the casing; the flexible device is arranged between the bottom surface of the casing and the end surface of the ball bowl; the bowl surface of the ball bowl faces to a cylinder opening of the casing; the hard beads are correspondingly arranged on the bowl surface of the ball bowl, and a plurality of small steel balls are uniformly distributed between the hard beads and bowl surface of the ball bowl; and after the barrel opening of the casing necking down, and the mouth rim diameter thereof is less than the diameter of hard beads, therefore, the hard beads, a plurality of small steel balls, the flexible device, and the ball bowl are restricted in the casing. The utility model can ensure the consistency and uniformity of the shape of rib strips on the materials, and meanwhile prevent the materials from producing internal stress caused by the abnormality of the deflection.
Description
Technical field
The utility model relates to the die head of rib on a kind of processing sheet plate face, relates in particular to a kind of used muscle head that rolls when processing has the rib of circle, arc and corner that is applicable on NC turret punch machine.
Background technology
For improving the structural strength or the aesthetics of thin plate, on some plate faces, often need the processing rib.Such as cover plate of host computer boxboard, casing or the like.Carrying out this man-hour that adds, generally be to adopt punch forming in the past.Punch forming processing needs higher mould input cost, and working (machining) efficiency is low, and the process-cycle is long.On some large-scale thin-slab structure spares (such as automobile door, protecgulum, bonnet etc.), when processing similar rib, needed die cost is higher, and the installation of mould, debugging difficulty are also bigger, and the scale of required supporting press is also very big.The inspiration that is subjected to cylindrical shell to roll muscle, in order to realize the processing of platen surface rib, what the someone designed roller type rolls the muscle head, utilizes the automatic feeding of equipment in horizontal plane X or Y direction, rolls the muscle head to roller type and applies certain pressure, rolls out rib on the plate face.But this technical scheme processing some when having arc, circle or rotation angle position, just be difficult to be competent at, mainly be because roller is disk-shaped, when corner, bending, movement interference can appear, the dimensional accuracy of rib at rotation angle position exerted an influence; Simultaneously, this interference also can have influence on the intensity of milled head or material, for milled head, can produce unbalance loading to milled head, damage milled head, sheet material, owing to produce an entad extruding when corner, " turning ", make the deflection inequality, produce internal stress or tear sheet material.
The utility model content
The utility model provides a kind of rolling bar model tool that can be used as numerical control press at above problem, rolls the muscle head to what thin plate carried out plate gluten bar processing and forming.
The technical solution of the utility model is: it comprises housing, elastic device, ball bowl, rolls muscle hard pearl and some little steel balls; Described housing is barrel-shaped; Described ball bowl is arranged in the housing, and cross sectional shape is slightly less than the cross sectional shape of housing, makes that the ball bowl can axially-movable in housing; Described elastic device is arranged between housing bottom surface and the ball bowl end face; The bowl face of described ball bowl is towards the nozzle of housing; Described hard pearl correspondence is arranged on the ball bowl bowl face, and described some little steel balls are distributed between the bowl face of hard pearl and ball bowl; After the bung reducing of described housing, its mouthful constrains in hard pearl, some little steel balls, elastic device and ball bowl in the housing along the diameter of diameter less than the hard pearl.
It also comprises the retainer of little steel ball, and described some little steel balls are movably connected on the retainer, and retainer is arranged between ball bowl bowl face and the hard pearl.
The muscle head that rolls of the present utility model, pressing piece when adopting the hard pearl as roll extrusion, the size that ball is gone up in any direction, profile are consistent, roll muscle processing when entering corner, the curved section of commentaries on classics arc, can not make material the situation of deflection ANOMALOUS VARIATIONS occur, thereby can guarantee uniformity, the uniformity of rib shape on the material, avoid simultaneously in the situation that makes the material production internal stress owing to deflection unusually.Because when roll extrusion, pearl need carry the pressure greater than deformation force, also want simultaneously to keep freely rolling on 360 ° of any directions, the utility model is provided with some little steel balls specially as the transmission part that rolls, and has avoided between pearl and ball bowl the excessive pearl inflexible situation of rolling that occurs of frictional force.The amount of feeding when guaranteeing roll forming, elastic device in the utility model adopts elastic force to wait greater than stage clip, dish spring or the high strength composite of rib deformation force and makes, simultaneously, and when requiring to reach deformation force, elastic device also need have certain amount of contraction, can be movable to guarantee pearl.

The specific embodiment
The utility model as shown in Figure 1, 2, it comprises housing 6, elastic device 5, ball bowl 4, roll muscle with hard pearl 1 and some little steel balls 2; Described housing 6 is barrel-shaped; Described ball bowl 4 is arranged in the housing 6, and cross sectional shape is slightly less than the cross sectional shape of housing 6, makes that ball bowl 4 can axially-movable in housing 6; Described elastic device 5 is arranged between the end face of housing 6 bottom surfaces and ball bowl 4; The bowl face of described ball bowl 4 is towards the nozzle of housing 6; Described hard pearl 1 correspondence is arranged on the bowl face top of ball bowl 4, and bowl face shape is consistent with the shape of hard pearl 1.Described some little steel balls 2 are distributed between the bowl face of hard pearl 1 and ball bowl 4; After the bung reducing of described housing 6, the diameter of its mouthful along 7 constrains in hard pearl 1, some little steel balls 2, elastic device 5 and ball bowl 4 in the housing 6 less than the diameter of hard pearl 1.
It also comprises the retainer 3 of little steel ball 2, and described some little steel balls 2 are movably connected on the retainer 3, and retainer 3 is arranged between 4 bowls of faces of ball bowl and the hard pearl 1.
