Description

金屬管架套環的沖壓模具Stamping die for metal pipe frame collar

本發明係有關於一種沖壓模具，尤指一種組合式金屬管架套環的沖壓模具。The invention relates to a stamping die, in particular to a stamping die of a combined metal pipe frame collar.

按，組合式金屬管架具有組裝與拆卸簡便，易於運輸、倉儲等多項優點，使得組合式金屬管架已為現代家庭、辦公室、開放式賣場不可或缺的物品，早期的組合式金屬管架，係以鎖螺件將架體組立起來，再將置物層組於架體上，該種金屬管架之組裝與拆卸均需使用工具，操作上麻煩不便，是以乃有不使用工具即可組立之置 物架出現，其中又以竹節式金屬管架最具代表性。According to, the modular metal pipe rack has many advantages such as simple assembly and disassembly, easy transportation and storage, making the modular metal pipe rack an indispensable item in modern homes, offices, and open stores. The early modular metal pipe racks , The frame is assembled by the lock screw, and then the storage layer is assembled on the frame. The assembly and disassembly of this kind of metal pipe frame requires the use of tools, which is troublesome and inconvenient to operate, so it is only necessary to use tools Assembled racks appeared, among which the bamboo-shaped metal tube rack was the most representative.

如第十二圖及第十三圖所示，即為目前習知之竹節式金屬管架，包含：四立桿91、複數定位套92及複數網架93，該四立桿91分別設置在四個端角位置，且該立桿91上均等距形成有複數環溝911，該定位套92係呈圓錐形，由兩對半片體對接套結於該立桿91上，內緣壁設有用以嵌入該立桿91環溝911內之凸肋921，該網架93四端角均連設有一呈中空圓錐形之套環931，使該網架93能以該套環931由該立桿91上端套人，並利用該套環931之內錐壁與該定位套92之外錐面緊迫配合而定位，令該網架93能與該立桿91相結合。As shown in the twelfth and thirteenth figures, it is the conventional bamboo-jointed metal pipe rack, which includes four vertical rods 91, a plurality of positioning sleeves 92 and a plurality of grids 93. The four vertical rods 91 are respectively arranged in four A plurality of annular grooves 911 are formed at equal intervals on the vertical rod 91, and the positioning sleeve 92 is in a conical shape. Two pairs of half-pieces are connected to the vertical rod 91 by abutting, and the inner edge wall is provided with With the ribs 921 embedded in the ring groove 911 of the vertical rod 91, the four end corners of the grid 93 are connected with a hollow conical collar 931, so that the grid 93 can pass the vertical rod through the collar 931 The upper end of 91 is sheathed, and the inner cone wall of the collar 931 is tightly fitted with the outer cone of the positioning sleeve 92 for positioning, so that the net frame 93 can be combined with the vertical rod 91.

該網架93之套環931一般係採用預先切割成預定形狀之板材，經初步加工捲曲成粗略中空圓錐形之環狀粗胚，接著將該粗胚整型成精確之中空圓錐形半成品，再利用車削方式將該中空圓錐形半成品內緣壁上端及下端分別加工出倒角(藉以具有導引作用及較佳安全性)，完成該套環931的製造。惟，該套環931製程繁複，相對增加製造工時，提高製造成本，不符合經濟效益，進而導致價格上不具備有競爭力。The collar 931 of the grid 93 generally adopts a plate that is pre-cut into a predetermined shape, and is crimped into a rough hollow cone-shaped rough embryo after preliminary processing, and then the rough embryo is shaped into a precise hollow cone semi-finished product. The upper end and the lower end of the inner edge wall of the hollow conical semi-finished product are respectively processed by turning to chamfer (to have a guiding effect and better safety), and the manufacture of the collar 931 is completed. However, the ferrule 931 has a complicated manufacturing process, which relatively increases manufacturing man-hours and increases manufacturing costs, which is not in line with economic benefits, and thus the price is not competitive.
