Problems solved by technology

[0005] Since the upper and lower layers of products are made of thinner aluminum parts, the sound insulation felt in the middle is thicker and the lower parts are artificially laid, the position may be shifted
As a result, after superimposing the upper aluminum parts for trimming process, the upper and lower aluminum parts are scattered due to the problem of the middle felt, which makes it difficult to control the precision of the stamped part...

Method used

The application makes two-layer product up and down by the riveting punch 8 of upper and lower die and die 6, reaches the effect of riveting in the upper and lower layers of the product in the product punching waste area, thereby solving the problem that the product does not increase the riveter The phenomenon that the upper and lower aluminum parts of the parts are scattered after the trimming is completed. This greatly solves the problem of part movement in the flanging process due to the loosening of the upper and lower layer products, repeated adjustment of the flanging gap, and product quality problems such as wrong edge of the flanging and poor buckling of the wrapping. Through the punching set in the hemming process, the riveting position of the punching wast...

Abstract

The invention discloses a riveting device for an automobile heat insulation part mold, and belongs to the technical field of automobile heat insulation part molds. The riveting device comprises a lower mold insert, wherein the lower mold insert is provided with a riveting device female mold; the riveting device female mold is provided with an anti-rotation surface; a pressing plate is also arranged in the lower mold insert; the pressing plate is matched with the anti-rotation surface of the riveting device female mold; an upper mold is provided with a riveting male mold; the riveting male moldis arranged in a fixing plate; a base plate is arranged at the bottom of the fixing plate; the riveting male mold, the fixing plate and the base plate are fixed with an upper mold seat through screws; and when the riveting male mold and the riveting female mold are closed, waste materials in punching areas of upper and lower layers of products can be tightly riveted together. By the riveting device structure, the phenomenon that three layers of parts in an automobile heat insulation part are scattered in the punching process can be well avoided, and the effect of well ensuring the product quality is achieved.

Example Embodiment

[0017]Examples:
[0018]Seefigure 1 withfigure 2, A riveting device for automotive heat insulation molds, comprising an upper mold part and a lower mold part connected to each other,
[0019]The lower mold part includes an insert block 1, a pressing plate 2, a screw 3, a screw plug 4, a spring 5, a die 6 and an ejector pin 7; the insert block 1 is provided with a hole, the screw plug 4, the spring 5, and the recess The mold 6 and the top pin 7 are arranged in the hole from bottom to top, and the insert block 1 is also provided with a mounting groove for installing the pressure plate 2 and a mounting screw hole for installing the screw 3, that is, the pressure plate 2 is installed In the mounting groove of the insert 1, the concave mold 6 is also provided with an anti-rotation surface 61, and the pressure plate 2 is matched with the anti-rotation surface 61; the pressure plate 2 is matched with the anti-rotation surface 61 of the concave mold 6 In order to achieve the problem of anti-rotation of the concave mold 6, especially to solve the problem of anti-rotation of the concave mold 6 in the undulating area of ​​the profile, then the whole lower mold part of the riveter is locked on the insert 1 of the lower mold part by the screw 3; The insert 1 of the lower mold part is assembled on the lower mold base to form the lower mold base assembly;
[0020]The upper die part includes a riveting punch 8, a fixing plate 9 and a backing plate 10. The fixing plate 9 is provided with a fixing hole for connecting with the rear end of the riveting punch 8, and the backing plate 10 is connected At the bottom of the fixed plate 9, the front end of the riveting punch 8 is connected with the top pin 7; the outer circle of the riveting punch 8 described in the upper die part of the riveter and the fixing hole of the fixed plate 9 adopt a transitional fit, Then set the backing plate 10 at the bottom to facilitate the adjustment of the depth of the riveting device in the later period; the riveting punch 8, the fixing plate 9, and the backing plate 10 are assembled with the upper mold base by screws and pins to form an upper mold base assembly;
[0021]This application uses the riveting punch 8 and the die 6 of the upper and lower die to achieve the effect of riveting the upper and lower layers of the products in the upper and lower layers of the product in the punching waste area of ​​the product, thereby solving the problem of the product when the riveting device is not added. The phenomenon that the upper and lower aluminum parts of the part are scattered after the trimming is completed. This greatly solves the flanging process caused by the scattering of the upper and lower products, and the repeated adjustment of the flanging gap, as well as the product quality problems such as the wrong flanging and the poor fastening of the hemming. Through the punching set in the hemming process, the riveting position of the punching waste area is cut off, so that no surface features that are inconsistent with the product will not be left on the product. After the hemming is completed, the parts will not be scattered because the circumferential position has been buckled. Through the inspection of the preliminary project, the fitter debugging time of similar parts has been shortened by 40 hours, and the parts using the riveter structure have also been highly conscientious by customers. The company has undertaken similar parts for many times. Therefore, through the structure of the riveting device for automobile heat insulation parts, it can reduce the debugging workload, shorten the mold manufacturing cycle, and reduce the cost of mold manufacturing, and win the trust of customers while further occupying market share
