Abstract
Description
Technical Field
[0001] This utility model relates to the field of shaping mechanism technology, and more specifically, to a planarity cold shaping mechanism. Background Technology
[0002] In industrial production, some products with large length-width-height ratios or soft materials are prone to plastic deformation due to uneven distribution of processing stress, such as the casing of mobile phones. This deformation not only affects the appearance but also the assembly of the finished product, and may even cause some functions of the finished product to fail, making it a defective product. Therefore, this type of product generally needs to undergo contour shaping, that is, flatness shaping, after production.
[0003] Due to internal stress, flatness defects may occur during the machining of 3C parts, requiring manual correction. However, manual correction has some problems:
[0004] 1. The correction force cannot be guaranteed to be uniform, and the flatness of the products after correction cannot be guaranteed to be qualified in all cases;
[0005] 2. Manual calibration can lead to fatigue and cannot be performed on a large scale;
[0006] 3. Manual operation cannot achieve precise position correction. Utility Model Content
[0007] In view of the problems existing in the prior art, the purpose of this utility model is to provide a planarity cold forming mechanism, which aims to solve the problems mentioned in the background art.
[0008] To solve the above problems, the present invention adopts the following technical solution:

[0010] A lower fixing plate has multiple positioning holes on its top, each positioning hole having a positioning rod movably embedded inside it, and an upper fixing plate is sleeved between the outer surfaces of the multiple positioning rods; and
[0011] A shaping component includes a lower pressure plate disposed on top of a lower fixed plate. A lower protective ring is installed on top of the lower pressure plate, an upper protective ring is installed on top of the lower protective ring, an upper pressure plate is installed on top of the upper protective ring, and multiple shaping blocks are disposed inside the upper protective ring.
[0012] As a preferred embodiment of this utility model, a plurality of guide blocks are fixedly installed on the top of the lower fixing plate.
[0013] As a preferred embodiment of this utility model, each guide block has a limiting protrusion fixedly connected to one side of its outer wall.
[0014] As a preferred embodiment of this utility model, the outer walls of both the upper and lower pressure plates are provided with multiple limiting slots.
[0015] As a preferred embodiment of this utility model, both the upper and lower protective rings have limiting notches on their outer walls.
[0016] As a preferred embodiment of this utility model, both the upper and lower protective rings are made of soft material. Beneficial effects
[0017] Compared with existing technologies, this utility model provides a planarity cold forming mechanism, which has the following beneficial effects:
[0018] 1. In this solution, the lower and upper pressure plates facilitate the clamping of the material to be processed. The internal shaping block helps to press against deformed areas. The shaping block is installed by screws. The upper fixed plate is driven by the hydraulic press to continuously approach the lower fixed plate and press down to correct the deformation of the material. The upper and lower protective rings work together to prevent scratches on the material and protect the outer surface of the material, greatly reducing the risk of product abnormalities.

The shaping block 405 is installed at the appropriate positions on the upper pressure plate 404 and the lower pressure plate 401 through the screw, and the shaping block 405 abuts against the deformed part of the material. The material is pressed by the lower pressure plate 404 and the upper pressure plate 401.
