Detailed Description
The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making clear and defining the scope of the present invention.
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 assembly of the washing machine box body rounding device according to the present invention. A washing machine box rounding device for bending a washing machine box comprises a machine body 1, an inner die holder 2 connected with the machine body 1, a rounding die 5 connected with the machine body 1, an up-down moving cylinder 8, a guide rail sliding block 10, a rounding floating cylinder 16 connected with the guide rail sliding block 10 and a compression die 12, wherein the up-down moving cylinder 8 is connected with the rounding die 5, the guide rail sliding block 10 is respectively connected with two side end parts of the rounding die 5, the compression die 12 is arranged above the inner die 3, and the compression die 12 is parallel to the rounding die 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 chamfer surface, 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 includes an axial center and a cylindrical surface surrounding the axial center, and the end of the rounding die 5 has a bearing 11 for reducing tangential friction. The rounding die 5 is connected to a rotating shaft 7 for driving the rounding die 5, and the rotating cylinder 6 is connected to the rotating shaft 7 for driving the rotating shaft 7 to rotate.
The rounding die 5 has an initial rolling position in which the rounding die 5 is located above the inner die 3 and a final rolling position in which the axis of the rounding die 5 is aligned in the vertical direction with the center of the chamfer cross section of the inner die 3. The central angle of the arc chamfer surface of the inner mold 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 mold 5 rolls to a final rolling position, the angle limiting column 13 is abutted to the side surface of the box body, the height limiting column 9 is connected with the up-down moving cylinder 8, and when the rounding mold 5 is positioned at an initial rolling position, the lower end surface of the rounding cylindrical surface is separated from the inner mold 3 by the thickness of the box body. In the drawings 1 and 2, the cylinder moves up and down to push the rounding assembly to the height limiting column through the guide rail sliding block, and the height limiting column can be quickly changed to adjust the working height of the rounding assembly, so that the coincidence of the rotation center and the center of the R angle of the internal mold is ensured. The rounding assembly as shown in fig. 3 uses two rotary cylinders to push the rounding mold to rotate around the center of the rotation shaft (rotation center).
Fig. 4 and 5 are the inner die for rounding the washing machine box body according to the present invention, which is inserted from the side groove of the inner die seat to the fixed position, and then the pressing block is screwed to fix. The R angle required after the rolling forming of the flattening piece is generally in the range of 5m to 45mm, so that the corresponding R angles of the internal mold have various specifications, and the internal molds at different R angles are quickly replaced through the groove pressing blocks. Because the feeding position of the workpiece is fixed, the upper surface of the internal mold is designed at the same height. The inner die R angles are all tangential to the upper surface, which results in the center height of the inner die R angles being different.
Fig. 9 is a diagram showing the start and end of the relative position of the R45 rounding mold and the rotation center of the washing machine box body rounding device according to the present invention, fig. 10 is a diagram showing the start and end of the relative position of the R5 rounding mold and the rotation center of the washing machine box body rounding device according to the present invention, and fig. 11 is the function of the front and rear angle limiting post of the rounding of the washing machine box body rounding device according to the present invention. When the rotary cylinder works, the rotation center coincides with the center of the internal mold, in order to realize the rounding function, the cylindrical surface of the rounding mold needs to be tangent to the R angle of the internal mold (actually spacing the thickness of the workpiece plate), but the radial positions of the internal mold with different R angles relative to the rotation center of the rounding mold need to be changed.
Fig. 6 is a floating circle rolling mechanism of a washing machine box body circle rolling device according to the invention, the whole is pushed by a rotating cylinder to rotate around a rotation center, and the two circle rolling floating cylinders drive a circle rolling die to do radial floating through guiding of a guide rail sliding block, so that the circle rolling die can always press a workpiece on the R angle surface of a lower die. And the bearings are arranged at the two ends of the rounding die, so that the rounding die can roll on the surface of a workpiece in the rounding action process, almost no tangential friction force of an R angle is generated, and the damage to the surface of the workpiece caused by relative sliding friction is avoided. The floating rounding mechanism can effectively improve debugging and test efficiency, and even if R angle change is caused by later die repair, or the rotation center and the center of the R angle of the inner die deviate slightly during centering, the rounding function can be realized as long as the position of the rounding die is in the stroke of the floating cylinder.
FIG. 7 shows a floating compression mechanism of the rounding device for the washing machine box body, wherein the flattening piece of the box body is warped to different degrees, so that the rounding quality is ensured, the consistency is improved, the compression mechanism is designed to compress the flattening piece close to the R angle position on the upper plane of the inner die, and before the rounding action, two floating compression cylinders push the compression die to compress the flattening piece through guide posts and linear bearings, and the compression die can float up and down to adapt to various R angle inner dies in the same way as the floating rounding mechanism.
Fig. 8 is a rebound compensation state (100 ° rotation of the round) of the case rounding device of the washing machine according to the present invention, and the R angle of the round case is less than 90 ° when the rotation angle of the round motion is 90 ° due to the torsional rebound deformation of the case after rounding. Therefore, the rounding angle is designed to be slightly larger than 90 degrees for compensation, and the corresponding circular arc angle of the R angle of the inner die can be uniformly designed to be 120 degrees, so that the rebound compensation angle of the general box body is enough. The deformation resilience of the box bodies with different materials and thicknesses is different, and the final position of the rounding die can be adjusted by changing the angle limiting column (quick-change mode), so that the compensation angle can be adjusted. The device is used for innovatively designing a rounding die according to various specifications of front and rear R angles of the pulsator box body of the washing machine, adopts a floating rounding mechanism to realize rounding forming of different R angles, and designs a floating pressing mechanism and an angle rebound compensation mechanism for improving rounding quality.
The above embodiments are only for illustrating the technical concept and features of the present invention, and are intended to enable those skilled in the art to understand the content of the present invention and to implement the same, but are not intended to limit the scope of the present invention, and all equivalent changes or modifications made according to the spirit of the present invention should be included in the scope of the present invention.
