[0039] To make the technical content of the utility model, the purposes and effects achieved more clear, the following will be explained in combination with the embodiments and the drawings.

[0040] The current manual edge pulling method has poor production stability and low production efficiency.

[0041] Based on this, please refer to Figures 1 to 10 The utility model provides a kind of edge pulling tool, with workbench 1, comprising: placing body 4, lifting and pressing assembly 2, first edge pulling assembly 3 and second edge pulling assembly 5.Placing body 4 is set on workbench 1, and placing body 4 top is equipped with accommodating cavity 41;Lifting and pressing assembly 2 is correspondingly set with accommodating cavity 41, and it is close to or away from accommodating cavity 41 along vertical direction.Specifically, lifting and pressing assembly 2 is correspondingly set with accommodating cavity 41, lifting and pressing assembly 2 is located just above accommodating cavity 41, in the direction perpendicular to workbench 1, the projection area of lifting and pressing assembly 2 coincides with the projection area of accommodating cavity 41.First edge pulling assembly 3 is correspondingly set with the inner side of accommodating cavity 41, and it is located between placing body 4 and pressing assembly.Specifically, first edge pulling assembly 3 is correspondingly set with the inner side of accommodating cavity 41, in the direction perpendicular to workbench 1, the projection area of first edge pulling assembly 3 can coincide with the projection area of accommodating cavity 41, and the coincident part is located in the inner side of accommodating cavity 41.Second edge pulling assembly 5 is set around the outer side of accommodating cavity 41 and is set on workbench 1.When operating, the action end of first edge pulling assembly 3 is close to or away from the inner side of accommodating cavity 41, and the action end of second edge pulling assembly 5 is close to or away from the outer side of accommodating cavity 41.

[0042] Specifically, the accommodating cavity 41 is used for placing the injection molding part and the decoration strip, the inner side of the accommodating cavity 41 corresponds to the side of the injection molding part not covered by the decoration strip, and the outer side of the accommodating cavity 41 corresponds to the side of the injection molding part covered by the decoration strip. Taking the decoration strip of the front or rear quarter window of the vehicle as an example, the inner edge of the triangular injection molding part corresponds to the inner side of the accommodating cavity 41, and the outer edge of the triangular injection molding part corresponds to the outer side of the accommodating cavity 41. Those skilled in the art can adjust the specific structure of the placing body 4 according to the type of the injection molding part and the decoration strip to be assembled, without specific limitation.

[0043] The lifting and pressing assembly 2 is arranged directly above the accommodating cavity 41, and after the lifting and pressing assembly 2 is lifted and pressed, the injection molding part and the decoration strip placed in the accommodating cavity 41 can be pressed to complete assembly. The first edge bending assembly 3 is arranged between the placing body 4 and the pressing assembly, and the injection molding part is bent by approaching or moving away from the inner side of the accommodating cavity 41. After the edge of the injection molding part is bent, the operator can place the decoration strip in the gap of the bent injection molding part. After the decoration strip is placed, the lifting and pressing assembly 2 is pressed to press the decoration strip and the injection molding part. During the pressing process of the lifting and pressing assembly 2, the second edge bending assembly 5 simultaneously acts, approaches or moves away from the outer side of the accommodating cavity 41, so as to bend the edge of the decoration strip. When the edge of the decoration strip is bent, the lifting and pressing assembly 2 is pressed to complete the assembly of the decoration strip in the injection molding part. After the assembly is completed, the first edge bending assembly 3, the second edge bending assembly 5 and the lifting and pressing assembly 2 are reset, and the operator takes away the assembled product, that is, one production action is completed.

[0044] It can be understood that the edge bending tool provided by the utility model can bend the edges of the injection molding part and the decoration strip from the inner and outer sides of the accommodating cavity 41 through the first edge bending assembly 3 and the second edge bending assembly 5, and assemble the decoration strip on the injection molding part through the lifting and pressing assembly 2. The whole process is simple and stable, can effectively reduce the working strength of the operator, and can avoid the quality problems caused by different manual bending forces and improve the product quality.

[0045] In some embodiments, the first edge pulling assembly 3 comprises a fixed plate 32, a first profiling piece 34, a first lifting structure 31 and a first driving mechanism 33. The fixed end of the first lifting structure 31 is arranged on the workbench top 1. The fixed plate 32 is arranged on the output end of the first lifting structure 31. The first driving mechanism 33 is arranged on the fixed plate 32. The first profiling piece 34 is arranged on the output end of the first driving mechanism 33. The first driving mechanism 33 is used to drive the first profiling piece 34 to approach or move away from the accommodating cavity 41. The first lifting structure 31 enables the first driving mechanism 33 and the first profiling piece 34 arranged on the fixed plate 32 to be lifted in the vertical direction. The first driving mechanism 33 drives the first profiling piece 34 to stretch or retract in the plane parallel to the workbench top 1, so that the first profiling piece 34 approaches or moves away from the accommodating cavity 41, thereby pulling the edge of the injection molded part. The first lifting structure 31 enables the first profiling piece 34 to descend from above the accommodating cavity 41 and then contact the injection molded part. This ensures that the edge of the injection molded part can be pulled around when the edge of the injection molded part is pulled, avoiding interference of the edge of the injection molded part, and ensuring the success rate of edge pulling. At the same time, the movement of the first profiling piece 34 in the plane parallel to the workbench top 1 makes the force of the first profiling piece 34 on the injection molded part more uniform, ensuring that there is no quality problem after edge pulling.

[0046] In some embodiments, the first profiling piece 34 comprises an arc-shaped block 341 and / or a straight line block 342, which are correspondingly arranged on the output end of the first driving mechanism 33. The first driving mechanism 33 drives the arc-shaped block 341 and / or the straight line block 342 to approach or move away from the accommodating cavity 41. A plurality of first driving mechanisms 33 are arranged on the fixed plate 32. The driving end of each first driving mechanism 33 is provided with an arc-shaped block 341 or a straight line block 342. This arrangement enables the first profiling piece 34 to adapt to the edge pulling requirements of injection molded parts of different specifications, improving the adaptability of the edge pulling tool. Specifically, the first driving mechanism 33 can be a telescopic pneumatic cylinder or a telescopic electric cylinder. Those skilled in the art can adjust the arrangement of the first driving mechanism 33 and the first profiling piece 34 according to actual needs, without specific limitation.

[0047] In some embodiments, the lifting and pressing assembly 2 comprises a pressing lifting structure 21, a pressing plate 22 and a pressing protrusion 23.

The pressing protrusion 23 is arranged on the side of the pressing plate 22 away from the pressing lifting structure 21. Specifically, the pressing protrusion 23 is arranged corresponding to the structure of the accommodating cavity 41, so that after the lifting and pressing assembly 2 is pressed down, the pressing protrusion 23 can assemble the decorative strip in the accommodating cavity 41 into the injection molded part. This arrangement enables the decorative strip to be assembled into the injection molded part under the action of the force in the vertical direction. The decorative strip is uniformly stressed as a whole, ensuring a good appearance.

[0048] Specifically, the pressing protrusion 23 does not contact the first edge-bending assembly 3 during the operation process, avoiding the collision between the lifting and pressing assembly 2 and the first edge-bending assembly 3 to cause safety problems.

[0049] Specifically, the first lifting structure 31 and the pressing lifting structure 21 can adopt a gantry structure, the base of the gantry is fixed on the workbench 1, and the fixed plate 32 or the pressing plate 22 is vertically lifted through the telescopic cylinder, telescopic electric cylinder, telescopic rod or screw rod structure arranged at the top of the gantry. Alternatively, the first lifting structure 31 and the pressing lifting structure 21 can adopt a lifting structure connected to an external rack, and the fixed plate 32 or the pressing plate 22 can be vertically lifted through the telescopic cylinder, telescopic electric cylinder, telescopic rod or screw rod structure. The person skilled in the art can adjust the setting form of the first lifting structure 31 and the pressing lifting structure 21 according to the actual needs, which is not limited specifically.

[0050] In some embodiments, the pressing plate 22 is provided with a avoiding opening 221 corresponding to the first edge-bending assembly 3. The pressing plate 22 is provided with an avoiding opening 221 corresponding to the position of the first edge-bending assembly 3, so that the pressing plate 22 does not contact and interfere with the first edge-bending assembly 3 after being pressed down, thereby ensuring the completion of the pressing action. At the same time, such arrangement enables the lifting and pressing assembly 2 and the first edge-bending assembly 3 to overlap in the vertical direction, reduces the thickness of the pressing protrusion 23, reduces the cost, and ensures uniform pressing force.

[0051] In some embodiments, the placing body 4 is provided with an edge-bending gap 42, and the second edge-bending assembly 5 passes through the edge-bending gap 42 and extends into the accommodating cavity 41. Specifically, the edge-bending gap 42 is distributed outside the accommodating cavity 41 and extends from the bottom of the accommodating cavity 41 to the top of the accommodating cavity 41. The arrangement of the edge-bending gap 42 enables the second edge-bending assembly 5 to contact the decorative strip in the accommodating cavity 41 and provide a force to the decorative strip towards the outside of the accommodating cavity 41 through displacement, thereby completing the edge-bending action of the decorative strip.

[0052] In some embodiments, the edge-bending gap 42 is provided with at least three. The three edge-bending gaps 42 enable the decorative strip to be uniformly stressed, avoiding excessive local stress on the decorative strip and ensuring stable production quality.

[0053] In some embodiments, the second edge bending assembly 5 comprises a fixing base 51, a second driving mechanism 52 and an edge bending jaw 53. The fixing base 51 is arranged on the workbench 1. The fixed end of the second driving mechanism 52 is connected with the fixing base 51. The edge bending jaw 53 is arranged at the output end of the second driving mechanism 52. The second driving mechanism 52 drives the edge bending jaw 53 to pass through the edge bending gap 42 and extend into the accommodating cavity 41. Specifically, the fixing base 51 is arranged on the workbench 1 corresponding to the edge bending gap 42. The second driving mechanism 52 can drive the edge bending jaw 53 to extend and retract in the accommodating cavity 41, so as to perform the edge bending action of the decorative strip.

[0054] In some embodiments, the edge bending jaw 53 has an edge bending protrusion 531 arranged and extending upward at the end away from the second driving mechanism 52. The edge bending protrusion 531 can increase the contact area of the edge bending jaw 53 with the decorative strip, so as to ensure the success rate of the edge bending action.

[0055] In some embodiments, the positioning assembly 6 is arranged around the placing body 4 and on the workbench 1. The positioning assembly 6 is arranged around the placing body 4, so that the decorative strip can be quickly positioned after being placed, thereby improving the work efficiency.
