Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of door hemming, in particular to an oblique wedge interactive pulley for a door hemming mould. Background Art
[0002] Generally, a motor vehicle door is composed of an outer door panel and an inner door panel, and some auxiliary tools are needed to hem the outer door panel and the inner door panel.
[0003] In the related art, a standard bevel wedge is generally used to edge the inner and outer panels of a vehicle door. However, after the bevel wedge enters the sheet to achieve pre-bending, interference will occur between the bevel wedge and the pre-bending insert, making it impossible for the bevel wedge to retract normally. When edge wrapping, if the sheet is between 45 and 55 degrees, a positive pressure knife can be used for direct positive pressure without the need for pre-pressure with a pre-pressure knife. However, flipping the edge of the outer panel to between 45 and 55 degrees not only increases the difficulty of designing the side-flipping mold, increases the mold process, and increases the mold production cost, but also fails to guarantee the pass rate of the outer panel side-flipping surface. Utility Model Content
[0004] The purpose of the utility model is to provide a door hemming mold wedge interactive pulley to solve at least one aspect of the problems and defects raised in the above-mentioned background technology.
[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0006] A door hemming mold wedge interactive pulley, comprising:
[0007] A base and a pulley guide plate arranged on the base;
[0008] A pre-bent insert is provided on one side of the top of the pulley guide plate;
[0009] Both ends of the pre-bending insert are provided with edge-wrapped oblique wedges, and both sides of the edge-wrapped oblique wedge are provided with pre-bending guide rods respectively;
[0010] A driving mechanism is provided on the side opposite to the pre-bent blade and is connected to the base;
[0011] A position sensor is arranged in the middle of the base;
[0012] One side of the edge-wrapped wedges at both ends is provided with a groove, a nitrogen cylinder mounting block is provided in the groove, and a nitrogen cylinder is provided on one side of the nitrogen cylinder mounting block.
[0013] The door hemming mold oblique wedge interactive pulley according to this solution has at least the following technical effects:
[0014] The car door hemming mold bevel interactive pulley integrates the bevel interactive pulley and the standard bevel, so that after the inner panel and the outer panel of the car door are combined and the hemming is completed, the pulley retreats, carrying the hemming bevel installed on it, and a certain gap is generated between the pre-bent blade at the window frame and the hemming bevel, so as to avoid interference between the hemming bevel and the pre-bent blade, so that the hemming bevel can be retreated normally, and at the same time, the qualified rate of the side flip surface of the car door outer panel can be guaranteed; and in the face of different hemming molds, it is only necessary to adjust the size of the pulley structure according to actual needs and adjust the pulley movement timing according to data requirements, so it is more widely used.
[0015] As a further solution of the utility model: a wedge assisting assembly is provided between the hemming wedges at both ends and is connected to the pre-bending blade.
[0016] Since a wedge assist assembly is provided between the hemming wedges at both ends and is connected to the pre-bending insert, the angle in the processing process can be better controlled and adjusted by increasing the pre-bending and hemming forces, which helps to improve the processing quality, ensure the close fit between the hemming wedge and the workpiece, and reduce possible defects and unevenness.
[0017] As a further solution of the utility model: the pulley guide plate also includes an inclined guide plate and a side guide plate.
[0018] The inclined guide plate and the side guide plate play a guiding and sliding role, and can keep the pulley guide plate in a stable motion trajectory during the pre-bending and hemming process. This stability can improve the processing accuracy and consistency, and ensure the fit and processing quality of the hemming wedge and the workpiece.
[0019] As a further solution of the utility model: a nitrogen cylinder impact block is arranged at the bottom of the pulley guide plate.
[0020] The nitrogen cylinder impact block can play a shock-absorbing role during the movement of the nitrogen cylinder, reduce impact and vibration, help improve the stability of the interactive pulley when retracting, and reduce errors and instability caused by vibration.

[0033] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the utility model and are not used to limit the utility model, that is, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0034] Therefore, the following detailed description of the embodiments of the utility model provided in the accompanying drawings is not intended to limit the scope of the utility model claimed for protection, but merely represents selected embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without making creative efforts are within the scope of protection of the utility model.
[0035] like Figure 1-5 The embodiment of the utility model shown is a door hemming mold oblique wedge interactive pulley, comprising: a base 101 and a pulley guide plate 102 arranged on the base 101; a pre-bending knife 103 is arranged on one side of the top of the pulley guide plate 102; both ends of the pre-bending knife 103 are provided with hemming oblique wedges 104, and both sides of the hemming oblique wedges 104 are respectively provided with pre-bending guide rods 105; a driving mechanism 106 is arranged on the opposite side of the pre-bending knife 103 and connected to the base 101; a position sensor 107 is arranged in the middle of the base 101; a groove 108 is arranged on one side of the hemming oblique wedges 104 at both ends, a nitrogen cylinder mounting block 109 is arranged in the groove 108, and a nitrogen cylinder 110 is arranged on one side of the nitrogen cylinder mounting block 109.
[0036] When in use, when the material sheet is placed on the fetal membrane, the interactive pulley is driven by the driving mechanism 106, and the pre-bent blade 103 contacts the material sheet first, so that the hemming wedge 104 reaches the hemming position, and the interactive pulley maintains pressure until the hemming is completed. The interactive pulley driving mechanism 106 loses the upward pressure on the pulley, and the pulley retreats to a safe area driven by the nitrogen cylinder 110. The position sensor 107 senses that the pulley has retreated into place, and outputs a signal to the manipulator, and the manipulator completes the material removal.
[0037] Specifically, the car door hemming mold bevel wedge interactive pulley integrates the bevel wedge interactive pulley and the standard bevel wedge, so that after the car door inner panel and outer panel are combined and the hemming is completed, the pulley retreats, carrying the hemming bevel wedge 104 installed on it, and a certain gap is generated between the pre-bent blade 103 at the window frame and the hemming bevel 104, so as to avoid interference between the hemming bevel 104 and the pre-bent blade 103, so that the hemming bevel 104 can be retreated normally, and at the same time, the qualified rate of the side flip surface of the car door outer panel can be guaranteed; and in the face of different hemming molds, it is only necessary to adjust the size of the pulley structure according to actual needs, and adjust the pulley movement timing according to data requirements, so it is more widely used.
[0038] like Figure 1 and Figure 3 As shown, a wedge assisting assembly 111 is provided between the hemming wedges 104 at both ends and is connected to the pre-bending blade 103 .
[0039] Specifically, since a wedge assist assembly 111 is provided between the hemming wedges 104 at both ends and is connected to the pre-bending insert 103, by increasing the pre-bending and hemming forces, the angles in the processing process can be better controlled and adjusted, which helps to improve the processing quality, ensure that the hemming wedge 104 fits tightly with the workpiece, and reduce possible defects and unevenness.
[0040] like Figure 4 As shown, the pulley guide plate 102 also includes an inclined guide plate 1021 and a side guide plate 1022 .
[0041] Specifically, the inclined guide plate 1021 and the side guide plate 1022 play a guiding and sliding role, and can keep the pulley guide plate 102 in a stable motion track during the pre-bending and hemming process. This stability can improve the processing accuracy and consistency, and ensure the fit and processing quality of the hemming wedge 104 and the workpiece.
[0042] like Figure 5 As shown, a nitrogen cylinder impact block 112 is provided at the bottom of the pulley guide plate 102 .
[0043] Specifically, the nitrogen cylinder impact block 112 can play a shock-absorbing role during the movement of the nitrogen cylinder 110, reduce impact and vibration, help improve the stability of the interactive pulley when retreating, and reduce errors and instability caused by vibration.
[0044] The above contents are merely examples and explanations of the structure of the utility model. The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the utility model or exceed the scope defined in the claims, they should all fall within the protection scope of the utility model.
