The invention will be further described with reference to the accompanying drawings.
Fig. 1 schematically shows a plate material and a jig according to an embodiment of the present invention, and fig. 2 is a top view of the jig according to the embodiment of the present invention; fig. 3 is a front view of a jig according to an embodiment of the invention. As shown in fig. 1 to 3, the jig 100 is applied in a bending apparatus and can assist in performing bending of a sheet material 200, for example, bending the sheet material 200 into an L-shaped or U-shaped structure. In this embodiment, the sheet 200 is selected as a material for manufacturing a casing of the washing machine and has a desired fold L1, a second hole, and a plurality of first holes, the second hole having a larger hole diameter than the first hole. Wherein the intended fold L1 is preferably a line segment drawn as desired on the body of the sheet 200 by a writing instrument or a hard object. However, under particular requirements, the intended fold L1 may not be displayed on the body of the sheet 200 to avoid its exposure affecting product aesthetics or production efficiency, which merely represents the desired location where one would expect to actually bend on the sheet 200.
As shown in fig. 2 and 3, the jig 100 includes a support assembly 1 and a plurality of positioning mechanisms 2. The support assembly 1 can be mounted on a table of a press bending apparatus and comprises a carrying surface capable of partially supporting the sheet 200, the carrying surface having a support edge 13 for supporting the desired fold L1 of the sheet 200. The positioning mechanism 2 comprises a telescopic member 21 provided in the support assembly 1 and a movable latch 22 provided on the telescopic member 21. The telescopic member 21 is preferably an environmentally friendly, energy-saving and low-cost cylinder (which is called a first cylinder for avoiding weight), but is not limited thereto, and may be a driving mechanism capable of linear reciprocation, such as an oil cylinder, a linear motor, or the like. When the plurality of telescopic members 21 drive the corresponding movable pins 22 to be respectively inserted into the plurality of first holes of the plate 200, the expected folded edge L1 of the plate 200 is forced to be aligned with the supporting edge 13 of the bearing surface, so that the plate 200 can be bent by the bending device and the actual folded edge generated during the bending process of the plate 200 is limited to be overlapped with the expected folded edge L1, as shown in fig. 1 in detail.
The jig 100 for bending equipment and assisting the bending of the sheet 200 mainly comprises a bearing assembly 1 and a positioning mechanism 2 arranged on the bearing assembly 1, wherein the positioning mechanism can drive a plurality of corresponding movable bolts 22 through a plurality of telescopic components 21 to be respectively inserted into first holes on the sheet 200, so that the expected folded edge L1 of the sheet 200 is forced to be aligned with the supporting edge 13 of a bearing surface, the actual folded edge generated by the sheet 200 in the bending process is limited to be coincident with the expected folded edge L1, and in this way, the sheet 200 can be better prevented from sliding relative to the bending equipment when being bent by the bending equipment, thereby reducing the risk that the sheet 200 is scratched in the bending process, reducing the risk that the actual folded edge of the sheet 200 is not coincident with the expected folded edge L1, and greatly reducing the rejection rate of the sheet 200 after being formed.
In this embodiment, the support assembly 1 comprises a base plate 11 and first and second bosses 12a, 12b provided on the base plate 11. Wherein the bearing surface is at least partially formed on the first boss 12a and the second boss 12b, that is to say the bearing surface is mainly composed of the surface 14a and the surface 14 b. The support edge 13 is formed on the first boss 12a and/or the second boss 12b. In the present embodiment, the number of support edges 13 may be one or two. When the number of the supporting edges 13 is one, they may be formed on the first boss 12a or the second boss 12b to ensure that the plate 200 forms an L-shaped structure after being bent; when the number of the supporting edges 13 is two, the two supporting edges 13 are respectively formed on the first boss 12a and the second boss 12b and are the farthest opposite sides on the first boss 12a and the second boss 12b, so as to ensure that the sheet 200 can form a U-shaped structure after being bent. In this embodiment, a part of the positioning mechanism 2 is embedded in the first boss 12a, and another part of the positioning mechanism 2 is embedded in the second boss 12b, so that the movable bolt 22 can not only extend out of the first boss 12a or the second boss 12b, but also completely retract into the first boss 12a or the second boss 12b.
In this embodiment, the jig 100 further includes a first correcting member 31 and a second correcting member 32 respectively disposed on the first boss 12a and the second boss 12b, and a first driving mechanism 4a and a second driving mechanism 4b disposed on the base plate 11 and capable of driving the first boss 12a and the second boss 12b respectively, where the first boss 12a and the second boss 12b are slidably disposed on the base plate 11, for example, the first boss 12a or the second boss 12b is disposed on the base plate 11 through a slide rail, so that the first boss 12a and the second boss 12b can move in opposite directions and in opposite directions under the driving of the first driving mechanism 4a and the second driving mechanism 4 b. When the first boss 12a and the second boss 12b are driven by the first driving mechanism 4a and the second driving mechanism 4b to move towards each other, the first correcting member 31 and the second correcting member 32 are forced to move towards each other to permit the sheet 200 to be sleeved on the first correcting member 31 and the second correcting member 32 through the second hole, and when the first boss 12a and the second boss 12b are driven by the first driving mechanism 4a and the second driving mechanism 4b to move away from each other, the first correcting member 31 and the second correcting member 32 are forced to move away from each other to symmetrically press the hole edge of the second hole and force the sheet 200 to move relative to the supporting assembly 1, thereby enabling the first hole of the sheet 200 to be aligned with the movable plug 22 of the positioning mechanism 2 so that the movable plug 22 is easier to be inserted into the first hole. The first driving mechanism 4a and the second driving mechanism 4b are preferably air cylinders (which are called second air cylinders for avoiding weight) which are environment-friendly, energy-saving and low in cost, but are not limited thereto, and may be driving mechanisms capable of linear reciprocating motion such as an oil cylinder, a linear motor, and the like.
In the present embodiment, the first correcting member 31 includes a base portion 31a provided in the first boss 12a in a recessed manner and two positioning projections 31b provided on the base portion 31a and arranged at intervals. The second correcting member 32 includes a base portion 32a disposed on the second boss 12b in a recessed manner and two positioning projections 32b disposed on the base portion 32a and arranged at intervals. Wherein the two positioning protrusions 31b and the two positioning protrusions 32b can be separately pressed against the hole edge of the second hole when the first correcting member 31 and the second correcting member 32 are moved to the maximum distance therebetween, so that the first hole of the sheet material 200 can be caused to be aligned with the movable latch 22 of the positioning mechanism 2, so that the movable latch 22 can be conveniently inserted into the first hole of the sheet material 200.
In this embodiment, the jig 100 further includes a stopper member 5 provided on the bottom plate 11. The stop means 5 are able to block the slab 200 when it is transported to the bearing surface on the racking assembly 1 and guide it over the first corrective member 31 and the second corrective member 32 after the slab 200 is released, whereby the manual dependency can be reduced. The stop member 5 is preferably a rectangular stop higher than the first boss 12a and the second boss 12b.
In this embodiment, the fixture 100 further includes a clamping mechanism disposed on the bottom plate 11. The clamping mechanism is arranged to be able to abut against opposite sides of the sheet 200 and clamp the sheet 200, thereby avoiding an accidental tilting of the edges of the sheet 200 during bending, and more safely avoiding the risk of the actual fold deviating from the intended fold L1. In order to save costs and increase the response speed, in a preferred embodiment, the clamping mechanism may include at least one pair of third cylinders 61 provided on the base plate 11 and symmetrically arranged, the at least one pair of third cylinders 61 being capable of clamping the sheet material 200 placed between the third cylinders 61.
Next, a method for using the jig 100 according to the embodiment of the invention is described. Firstly, the sheet 200 transported to the carrying surface can be blocked by the stop part 5, falls down and is sleeved on the first correcting member 31 and the second correcting member 32, and secondly, the first boss 12a and the second boss 12b on the bottom plate 11 can move oppositely under the drive of the first driving mechanism 4a and the second driving mechanism 4b, and force the first correcting member 31 and the second correcting member 32 to move oppositely, so that the second hole on the sheet 200 is conveniently sleeved on the first correcting member 31 and the second correcting member 32. The first boss 12a and the second boss 12b are also capable of moving back to back under the drive of the first driving mechanism 4a and the second driving mechanism 4b, and force the first correcting member 31 and the second correcting member 32 to move back to back, so that the hole edge of the second hole is symmetrically pressed, the plate 200 is forced to move relative to the supporting assembly 1, and each positioning protrusion is pressed on different areas of the hole edge of the second hole, so that a supporting and expanding effect is formed, and the first hole of the plate 200 is aligned with the movable bolt 22 of the positioning mechanism 2. Then, the edge of the sheet 200 is clamped by the clamping mechanism, and the plurality of telescopic members 21 drive the corresponding movable pins 22 to be respectively inserted into the plurality of first holes of the sheet 200, so as to ensure that the expected folded edge L1 of the sheet 200 is aligned with the supporting edge 13 of the bearing surface, so that the sheet 200 can be bent by the bending device and the actual folded edge generated in the bending process of the sheet 200 is limited to coincide with the expected folded edge L1.
In summary, the jig solves the problem that the position of the sheet 200 is difficult to be reliably restrained, so that the risk that the sheet 200 is scratched in the bending process and the risk that the actual folded edge of the sheet 200 is not overlapped with the expected folded edge L1 can be reduced, and the rejection rate of the sheet 200 after being formed is greatly reduced.
