Three parts of the inner assembly (the inner ring, the roller and the retainer) of the tapered roller bearing depend on the retainer to fix the position relationship, and the riveting process is to make the inner ring and the roller relatively fixed by utilizing the extrusion deformation of the retainer and have a relative sliding relationship without scattering, so that the riveting process is an important process for producing the tapered roller bearing and a riveting female die is needed;
the shape of the existing bearing riveting die is fixed in a machine tool, so that continuous automatic operation can be realized; however, the full-automatic assembly line female die has the following disadvantages;
1. The size of the female die is not in direct proportion to the size of the riveted product, namely, if the equipment can process products in a range, the shape and the specification of the female die are consistent, so that the actual working part of the small-product riveting die occupies a small part of the whole die, and the material utilization rate is low;
2. One model corresponds to one mould, a large number of steel materials are needed to be processed and manufactured into female dies (bearing steel and quenching), and the cost is very high;
3. The appearance structure is related to the lathe bed (embedded), the appearance structure is large, the volume is generally 260X100mm, the weight is about 15 kg, and the labor intensity for changing and activating the operation staff is large (as shown in figure 1).
Disclosure of utility model
The utility model aims to provide a riveting concave die bracket, which solves the problems of low utilization rate, high cost and inconvenient replacement of the existing concave die.
In order to achieve the above purpose, the present utility model provides the following technical solutions: the riveting concave die bracket comprises a concave die bracket body, wherein the concave die bracket body comprises a concave die bracket and a concave die seat; the die holder is provided with a mounting groove, the die seat is arranged in the mounting groove, a filling cavity is formed between the die holder and the die seat, and a lining is arranged in the filling cavity.
Further, a screw is arranged on the outer wall of the female die bracket, threaded holes matched with the screw are formed in the outer walls of the female die bracket and the female die holder in a penetrating mode, and one end of the screw is abutted to the outer wall of the female die holder; the female die holder can be tightly propped up, so that the female die holder, the bushing and the female die holder are prevented from shaking.
Further, the lining is made of nylon; the nylon can reduce the weight of the die and reduce the labor intensity of changing and activating by operators.
Compared with the prior art, the utility model has the following beneficial effects:
the die bracket body is arranged in the mounting groove of the existing equipment table, the die bracket is arranged on a machine tool as a fixing piece, the old structural die or the miniaturized design die is only required to be taken out when the die is replaced, and the inner components to be riveted with different types, different outer diameters and different heights are embedded and fixed by adopting the bushing, the die holder and the screw auxiliary piece;
The female die bracket is embedded into a fixing groove arranged on the equipment table and fixed to form a combined female die with the same structure as the original tool, the bushing is filled into a filling cavity between the female die bracket and the female die seat, the screw is arranged in threaded holes of the female die bracket and the female die seat, one end of the screw is used for tightly propping the female die seat to form a combined female die with the same structure as the original tool, the inner component to be riveted is arranged in the matched female die seat, and riveting processing operation can be carried out on the inner component to be riveted;
When the die is replaced, the screw is taken out, after the bushing and the die holder are taken out, only one set of bushing and new die holder are needed to be replaced when the die is replaced, and finally the inner assembly to be riveted is embedded into the die holder and fixed by the screw;
The bushing is made of nylon, has light weight, reduces the overall weight of the die, has small processing difficulty, low cost and long wear-resistant service life, greatly reduces the processing cost of the female die, reduces the maintenance and management cost, reduces the labor intensity of operators during the die change, simultaneously improves the die change speed and improves the efficiency.
