Description

Technical Field

[0001] The invention relates to the technical field of automobile stamping dies, in particular to a retracting inclined wedge mechanism for a fender lamp foot flanging die reset block. Background Art

[0002] With the development of the automobile industry and the progress of the times, traditional automobile exterior design can no longer meet people's aesthetic needs. As a result, some strange shapes often appear in automobile exterior covers, which also puts higher requirements on mold design and manufacturing level.

[0003] At the same time, the demand of automobile companies to reduce mold costs has caused the problem of reducing the number of mold processes in many parts manufacturing processes. When the product shape has a negative angle of the flange, it is easy for the work content in the first sequence to be unable to be rolled back, resulting in an increase in the number of processes and a waste of costs.

[0004] At present, most of the mold retraction and reset blocks are in the form of single-direction retraction, with a relatively large retraction stroke and a relatively large occupied space, which increases the difficulty of mold design; for example, patent CN104210088A discloses a flanging forming mold, including a quick switching drive mechanism, a side rotating bevel wedge assembly, a front bevel wedge assembly and a rear bevel wedge assembly, the quick switching drive mechanism includes a switching drive cylinder, an inclined guide plate, a main bevel wedge drive leg, a spring, a balance guide column and an upper mold seat, the switching drive cylinder is connected to the inclined guide plate, the spring and the balance guide column are respectively arranged on the upper mold seat, the main bevel wedge drive leg is connected to the spring, the main bevel wedge drive leg and the parallel guide column are a moving pair, and the main bevel wedge drive leg is connected to the side rotating bevel wedge assembly. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a retracting inclined wedge mechanism for a fender lamp foot flanging mold reset block, so as to achieve the purpose of reducing the retracting stroke and saving space.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0007] The fender lamp foot flanging mold reset block retracts the inclined wedge mechanism, includes a fender lamp foot flanging knife block, and also includes a mother inclined wedge structure and a sub-oblique wedge structure. The mother inclined wedge structure is movably arranged on the lower mold body of the mold, and the sub-oblique wedge structure is movably arranged on the mother inclined wedge structure. The fender lamp foot flanging knife block is fixed on the sub-oblique wedge structure.

[0008] Further:

[0009] The moving direction of the mother angular wedge structure is perpendicular to the moving direction of the sub-angular wedge structure.

[0010] A guide structure is provided corresponding to the female wedge structure, and the guide structure includes a side guide plate and a pressure block.

[0011] A nitrogen spring is provided on one end of the female angular wedge structure corresponding to the sub-angular wedge structure.

[0012] A group of grooves are arranged side by side on the female wedge structure, and a plunger is arranged corresponding to each groove.

[0013] A protruding structure is provided at one end of the sub-wedge structure, and a sliding plate is provided on the top of the sub-wedge structure corresponding to the protruding structure.

[0014] A bottom guide plate is provided at the bottom of the female inclined wedge structure corresponding to the sub-oblique wedge structure.

[0015] The raised structure comprises a vertical raised portion and a top portion, and the vertical raised portion and the top portion are an integrated structure.

[0016] A sub-wedge inserter is provided on the inner side of the top of the protruding structure.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] The retraction wedge mechanism structure of the fender lamp foot flanging die reset block is reasonably designed, and it can be retracted in two directions, which greatly saves the space occupied by the reset block, saves space from the overall stamping die, and achieves cost savings; and to a certain extent, it increases the space for plate removal, increases the safety of automatic mold removal, and provides faster production speed for busbar production.

[0026] The specific implementation modes of the present invention will be further explained in detail below through the description of embodiments with reference to the accompanying drawings.

[0027] like Figures 1 to 4 As shown, the fender lamp foot flanging mold reset block retracts the bevel wedge mechanism, including a fender lamp foot flanging knife block 6, a mother bevel wedge structure 1 and a sub-bevel wedge structure 5; the mother bevel wedge structure is movably arranged on the lower mold body of the mold, the sub-bevel wedge structure is movably arranged on the mother bevel structure, and the fender lamp foot flanging knife block is fixed on the sub-bevel structure.

[0028] The retraction wedge mechanism structure of the fender lamp foot flange mold reset block of the present invention is reasonably designed, and it can be retracted in two directions, which greatly saves the space occupied by the reset block, saves space from the stamping mold as a whole, and achieves cost savings; and to a certain extent, it increases the space for taking out the plate parts, increases the safety of the automatic taking out of the mold, and provides a faster production speed for busbar production.

[0029] The moving direction of the female beveled wedge structure 1 is perpendicular to the moving direction of the sub-beveled wedge structure 5. The sub-beveled wedge structure retracts first, and then the female beveled wedge structure retracts, which is beneficial for removing the workpiece with negative angle flanging.

[0030] A group of grooves are arranged side by side on the female angular wedge structure, and a plunger 4 is arranged corresponding to each groove, so that the operation is stable and reliable. A guide structure is arranged corresponding to the female angular wedge structure, and the guide structure includes a side guide plate 2 and a pressure block 3. A nitrogen spring for movement is arranged on the lower mold body corresponding to the female angular wedge structure, and the operation of the working state and the retracting state is realized by the cooperation of the plunger and the nitrogen spring.

[0031] A bottom guide plate 10 is provided at the bottom of the female wedge structure corresponding to the sub-wedge structure, and a pressure plate 7 is provided at the top of the sub-wedge structure; a protruding structure is provided at one end of the sub-wedge structure, and a slide plate 8 is provided at the top of the female wedge structure corresponding to the protruding structure, so that the operation is stable and reliable.

[0032] The raised structure includes a vertical raised portion and a top portion, and the vertical raised portion and the top portion are an integrated structure; a sub-wedge insert is provided on the inner side of the top of the raised structure, and a nitrogen spring 9 is provided on one end of the female wedge structure corresponding to the sub-wedge structure; the working state and the retraction state are realized by the cooperation of the insert and the nitrogen spring.

[0033] The inclined wedge mechanism of the present invention is a composite inclined wedge mechanism formed by combining a mother inclined wedge structure and a sub-oblique wedge structure. The mechanism can greatly save the space occupied by the reset block, save space from the overall stamping die, and achieve cost savings.

[0034] The above is only an explanation of the preferred embodiments of the present invention, and the above technical features can be arbitrarily combined to form multiple embodiments of the present invention.
