Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The edge covering equipment suitable for the automobiles comprises an arc cutter 2, wherein one end of the arc cutter 2 is used for covering the workpiece 1; one end of the circular arc knife 2 for edge covering comprises a cambered surface 201, a vertical surface 202, a first horizontal surface 203 and a second horizontal surface 204; the first horizontal plane 203 is tangent to one end of the cambered surface 201, and the second horizontal plane 204 is tangent to the other end of the cambered surface 201; the second horizontal plane 204 has a greater level than the first horizontal plane 203. The arc surface 201 is used for bending and taping the workpiece 1.
It should be noted that, in fig. 3, the circular arc knife 2 is compared with the existing bag Bian Daoju, and is characterized in that the contact surface between the circular arc knife and the workpiece 1 is optimized into a smooth curved surface, and in the process of edge wrapping, the force born by the workpiece 1 is always perpendicular to the tangent line of the curved surface.
Further, as shown in fig. 2, the workpiece 1 includes a bending section 101 and a main body section 102, and the bending section 101 and the main body section 102 are of an integral structure. Before the edge is not covered, the included angle between the bending section 101 and the horizontal direction is 0-100 degrees, and after the edge is covered, the bending section 101 and the main body section 102 are parallel and not collinear.
It should be noted that, in this embodiment, when the angle of the workpiece 1 is slightly greater than 90 ° with respect to the horizontal plane, the plate cannot be pressed inward by the horizontal force generated by the common blade, and only the plate can be pressed by the horizontal force generated by the circular arc blade 2. It can also be seen from fig. 2 that the three positions a, b and c of the workpiece are distributed corresponding to the initial position, the pre-treatment position and the compacting position.
Further, the stress direction of the bending section 101 of the bag Bian Shi is perpendicular to the tangent line of the stress point on the cambered surface 201; the included angle between the force applied by the bending section 101 and the horizontal direction is a first included angle; the first included angle varies with different stress points on the arc surface 201, and the value range is 0-90 degrees.
It should be noted that, the circular arc knife 2 acts on the workpiece 1, and the acting force F perpendicular to the tangential direction of the arc surface 201 is the main acting force of the knife block on the plate. In fig. 3, the force applied to the workpiece 1 is F, the included angle between F and the horizontal direction is θ 1, and in addition, F is always perpendicular to the tangent line of the force applying point on the arc surface 201. Thus, the angle θ 1 in fig. 3 is a variable value. The force in the horizontal direction of F is Fcos theta 1, which is the main force that causes the workpiece 1 to turn inwards, and this force also varies with theta 1. Whereas in the prior art tool of fig. 1, angle θ 2 is always constant, so Fcos θ 2 is also always constant. In this embodiment, the smaller θ 1＜θ2 is, the larger the component force along the horizontal direction is, and the better the effect of buckling the plate inwards is, so that the circular arc knife 2 can simultaneously give consideration to the modeling and the stress of the workpiece 1, so that the workpiece 1 with the first included angle slightly larger than 90 degrees can be hemmed, and has good forming effect.
Further, the workpiece 1 is any one of front cover sheet metal, side door sheet metal and rear cover sheet metal of an automobile.
It should be noted that the edge covering device and the process generally have a great deal of application in the field of automobile body sheet metal of automobiles, and the workpiece 1 of the embodiment designs automobile body sheet metal.
Further, as shown in fig. 4, the edge covering device further comprises a tire mold 3, a lifting table 4, a driving device 5 and a knife rest 6; wherein the die 3 is used for placing the workpiece 1; the lifting table 4 is arranged at the lower side of the tire mold 3 and is used for jacking the tire mold 3 to approach the circular arc knife 2; the driving device 5 is arranged at the lower side of the lifting platform 4 and is used for transmitting power to the lifting platform 4; the knife rest 6 is positioned at one side of the tire mold 3 and is used for installing the circular arc knife 2. In addition, the driving device 5 is provided with a driving motor that transmits power to the elevating table 4 through mechanical transmission. Mechanical transmissions include gear transmissions and worm transmissions. In addition, as shown in fig. 5, in this embodiment, the circular arc knife 2 has a generally trapezoidal block structure, one end of which is fixed on the knife rest 6, and the other end of which has a cambered surface 201 on the lower surface, and abuts against the workpiece 1 through the cambered surface 201.
In operation, the driving device 5 drives the die 3 on the lifting table 4 and the workpiece 1 on the die 3 to move toward the fixed circular arc knife 2, and presses the workpiece 1 to the pre-hemming position by the acting force of the circular arc knife 2 on the workpiece 1.
Although the utility model has been described in detail with reference to the foregoing embodiments, it will be understood by those of ordinary skill in the art that: the technical scheme described in the foregoing embodiments can be modified or some technical features thereof can be replaced by equivalents; such modifications and substitutions do not depart from the spirit and scope of the technical solutions of the embodiments of the present utility model.
