Referring to fig. 1 to 3, fig. 1 and 2 are perspective views of a washing machine box body rounding device according to the present invention, and fig. 3 is a rounding component of the washing machine box body rounding device according to the present invention. The utility model provides a washing machine box rounding device for buckling washing machine box, includes organism 1, the interior die holder 2 that is connected with organism 1, the rounding mould 5 that is connected with organism 1, reciprocate cylinder 8, guide rail slider 10, the rounding floating cylinder 16 that is connected with guide rail slider 10, hold-down die 12, reciprocate cylinder 8 and be connected with rounding mould 5, guide rail slider 10 is connected respectively in the both sides tip of rounding mould 5, hold-down die 12 sets up in the top of centre form 3, hold-down die 12 is on a parallel with rounding mould 5.
The inner die holder 2 is provided with an inner die 3 for controlling the bending angle of the box body, the inner die 3 is provided with a circular arc-shaped chamfer surface, and the inner die 3 is detachably connected with the inner die holder 2; the inner die holder 2 is provided with a slot 14 and a pressing block 15, the inner die 3 is inserted into the inner die holder 2 from the end part of the slot 14, and the pressing block 15 locks the inner die 3.
The rounding die 5 comprises a shaft center and a rounding cylindrical surface surrounding the shaft center, and the end of the rounding die 5 is provided with a bearing 11 for reducing tangential friction. The rounding die 5 is connected with a rotating shaft 7 for driving the rounding die 5, and the rotating cylinder 6 is connected with the rotating shaft 7 for driving the rotating shaft 7 to rotate.
The rounding die 5 has an initial rolling position at which the rounding die 5 is positioned above the inner die 3 and at which the axis of the rounding die 5 is aligned in the vertical direction with the center of the circle of the chamfered cross section of the inner die 3, and an end rolling position. The central angle of the circular arc chamfer surface of the inner die 3 corresponding to the initial rolling position and the final rolling position is 120 degrees. The machine body 1 is provided with an angle limiting column 13 and a height limiting column 9, when the rounding die 5 rolls to the end rolling position, the angle limiting column 13 is abutted against the side face of the box body, the height limiting column 9 is connected with the up-and-down moving cylinder 8, and when the rounding die 5 is located at the initial rolling position, the lower end face of the rounding cylinder and the inner die 3 are separated from each other by the thickness of the box body. As shown in the attached figures 1 and 2, the up-and-down moving air cylinder pushes the rounding component to the height limiting column through the guide of the guide rail sliding block, the height limiting column can be used for quickly changing and adjusting the working height of the rounding component, and therefore the rotating center is enabled to coincide with the center of the R angle of the inner die. The rounding assembly as shown in fig. 3 uses two rotating cylinders to drive the rounding die to rotate around the center of the rotating shaft (rotating center).
Fig. 4 and 5 are a rounding internal mold of a washing machine box body rounding device according to the utility model; the internal mold is inserted into the side groove of the internal mold base, and the pressing block is screwed up and fixed after the internal mold base reaches a fixed position. The R angle of the flattening part is required to be generally in the range of 5-45 mm after rounding forming, so that the R angle of the corresponding inner die has multiple specifications, and the inner die with different R angles is quickly replaced through the groove pressing block. Because the feeding position of the workpiece is fixed, the upper surface of the inner die is designed at the same height. And the inner mold R angles are tangent to the upper surface, which causes the center heights of the inner mold R angles to be different.
Figure 9 is according to the utility model discloses a washing machine box rounding device's R45 rounding mould and rotation center relative position top and end, figure 10 is according to the utility model discloses a washing machine box rounding device's R5 rounding mould and rotation center relative position top and end, figure 11 is according to the utility model discloses a washing machine box rounding device is the effect of the spacing post of angle around the rounding. When the rotating cylinder works, the rotating center coincides with the center of the inner die, in order to realize the function of rounding, the cylindrical surface of the rounding die needs to be tangent to the R angle of the inner die (the thickness of the workpiece plate is actually spaced), but the radial position of the rounding die relative to the rotating center must be changed along with the inner die with different R angles.
Figure 6 is according to the utility model discloses a washing machine box rounding device's round mechanism that rolls floats wholly promotes by rotating cylinder and rotates around rotation center to it is radial unsteady to pass through the guide rail slider direction with two round floating cylinder and drive the round mould, and the round mould just can start pressing the work piece on lower mould R angle surface at all times like this. And bearings are arranged at two ends of the rounding die, so that the rounding die can roll on the surface of a workpiece in the rounding action process, R-angle tangential friction is hardly generated, and the damage to the surface of the workpiece caused by relative sliding friction is avoided. This floating rounding mechanism can effectively promote debugging and test efficiency, even later stage is repaiied the mould and is leaded to the R angle change, perhaps the centre of rotation deviates a little with centre form R angle center during the centering, as long as the rounding mould position all can realize the rounding function in the cylinder stroke that floats.
FIG. 7 is a floating hold-down mechanism of a washing machine box body rounding device according to the present invention; because the box flattening piece warps in different degrees, in order to ensure the rounding quality and improve the consistency, a pressing mechanism is designed to press the flattening piece close to the R angle position on the upper plane of the inner die, before rounding action, two floating pressing cylinders push a pressing die to press the flattening piece through guide pillars and linear bearings in a guiding manner, and the pressing die can be floated up and down to adapt to various R angle inner dies similarly to the floating rounding mechanism.
Fig. 8 shows the springback compensation status of the washing machine box body rounding device according to the present invention (rounding rotation 100 °); because the box body is distorted and rebounded to deform after being rounded, when the rotation angle of the rounding action is 90 degrees, the R angle of the box body is smaller than 90 degrees after being rounded. Therefore, the designed rounding angle is slightly larger than 90 degrees for compensation, and the corresponding inner mold R angle arc angles can be uniformly designed to be 120 degrees enough for the rebound compensation angle of a common box body. The deformation resilience amounts of the box bodies made of different materials and thicknesses are different, and the final position of the rounding die can be adjusted by replacing the angle limiting column (in a quick-change mode), so that the compensation angle is adjusted. The device carries out innovative design on the rounding die aiming at various specifications of front and rear R angles of the impeller box body of the washing machine, realizes rounding forming of different R angles by adopting the floating rounding mechanism, and designs the floating pressing mechanism and the angle springback compensation mechanism for improving the rounding quality.
