Abstract

The utility model provides a rolling rib upper mold used for a rotation work position of a numerical control turret punching machine, which relates to a mold head for processing upper ribs of a thin plate surface. The rolling rib upper mold comprises a mold seat, wherein a rigid ball rolling rib head, a first elastic roller and a second elastic roller are arranged on the lower end surface of the mold seat, the axial lines of the rolling rib head, the first roller and the second roller are positioned on a vertical surface vertical to the same plane, the first roller and the second roller are positioned at both sides of the rolling rib head, the lowest points of the first roller and the second roller are higher than the lowest point of the rolling rib head, and the height difference is the depth of the rib. The utility model combines the mold head rotation function and the automatic material feeding function of the numerical control turret punching machine, and can conveniently realize the high-efficient and high-precision process of the rolling ribs.

Description

The NC turret punch machine rotary work station is with rolling the muscle patrix

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 patrix 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 can be used as the rolling bar model tool that has circle, arc and corner shape muscle groove in the NC turret punch machine multistation integration of operation system.

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, has circle, arc and corner shape rib to carry out the NC turret punch machine rotary work station of processing and forming with rolling the muscle patrix to thin plate plate mask.

The technical solution of the utility model is: comprise die holder, what be provided with the hard pearl in the die holder lower surface rolls muscle head, flexible pressure roller one and pressure roller two, the axis that rolls muscle head, pressure roller one and pressure roller two is on the same facade perpendicular to horizontal plane, pressure roller one and pressure roller two are positioned at and roll muscle head both sides, the minimum point of pressure roller one and pressure roller two is higher than the minimum point of rolling the muscle head, and difference in height is the degree of depth of described muscle.

The axis of pressure roller one or pressure roller two is downward-sloping toward the outer side.

Described facade departs from die holder axial line 0.1-5mm.

The muscle patrix 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.We find that thin plate is after rolling muscle processing, because the phenomenon of warpage can appear in distortional stress, for overcoming this phenomenon, the utility model is provided with flexible pressure roller respectively rolling muscle head both sides, overcome stress deformation, it is consistent with the degree of depth of processed muscle that elasticity pressure roller lower extreme point and the difference in height of rolling muscle head lower extreme point are set to, and some material is not enough to overcome stress deformation under this difference in height, can also increase difference in height between the two.In addition, the medial and lateral of arc, the stress deformation amount of plate is inconsistent, and for this reason, the utility model has also proposed the technical scheme that outside pressure roller axis tilts, and can consider that also both all tilt, and outside tilt quantity is greater than the scheme of inboard tilt quantity.At last, as best one can little, lighter for making the rolling and processing deflection, the utility model has also proposed the technical scheme of facade skew.The die head spinfunction and the automatic feeding function of the utility model combining with digital control rotating tower punch can realize easily rolling that muscle is efficient, high accuracy processing.

The specific embodiment

As shown in Figure 5, the utility model is mainly used in the muscle 6 that has circle, arc and corner configurations on the processing sheet 5 plate faces.After the cold-working processing, the deflection of deformed area 7, the arc outside can cause thin plate 5 unusual, irregular warpages greater than the deflection of the inboard deformed area 8 of arc.

The utility model improves the flatness of processing back thin plate 5 for overcoming above-mentioned situation, and the technical measures of proposition are as follows:

As shown in Figure 1, 2, comprise die holder 1, what be provided with the hard pearl in die holder 1 lower surface rolls muscle head 3, flexible pressure roller 1 and pressure roller 24, the axis that rolls muscle head 3, pressure roller 1 and pressure roller 24 is on the same facade perpendicular to horizontal plane, pressure roller 1 and pressure roller 24 are positioned at and roll muscle head 2 both sides, the minimum point of pressure roller 1 and pressure roller 24 is higher than the minimum point of rolling muscle head 3, and difference in height is the degree of depth of described muscle.

The utility model has also proposed second embodiment for solving the uneven problem of arched ribs medial and lateral deflection, and as shown in Figure 3, the pressure roller 1 outside will being in or the axis of pressure roller 24 are downward-sloping toward the outer side.Also can take two pressure rollers all downward-sloping laterally, be positioned at the means of the pressure roller tilt quantity increasing in muscle 6 outsides.

The utility model has also proposed the 3rd embodiment for reducing deflection, making rolling and processing light, and as shown in Figure 4, the direction of motion departs from die holder 1 axial line 0.1-5mm backward during with respect to processing with described facade.This facade is the facade that comprises the axis that rolls muscle head 3, pressure roller 1 and pressure roller 24.In addition, in application, should keep projection line and the muscle 6 of this facade on horizontal plane perpendicular.
