Abstract
The utility model provides a rolling hemming shaping tool. An idler wheel is connected with the front end of a cutter bar through a shaft, and the idler wheel is in clearance fit with the shaft. The rolling hemming shaping tool is simple and reliable in structure, can carry out machining or shaping on a tubular part by means of an existing ordinary lathe, improves production efficiency and quality, saves production cost, and is particularly suitable for carrying out hemming shaping machining on tubular parts in a limited quantity and of various specifications.
Description
Technical field
The utility model belongs to the technical field of mechanical stitch crimping processing, especially relates to a kind of instrument that carries out the shaping of roll extrusion crimping with lathe.
Background technology
At present, to tubular member crimping machining the time, generally adopt punch press to process by the mode of particular manufacturing craft.In the actual production, the particular manufacturing craft process-cycle is long, manufacturing expense is high, and this type of mode is invested greatly, and production cost is high, particularly the tubular member crimping processing of the many specifications of small lot is not suitable for more.For this reason, also have directly and change system into the crimping shaping tool with lathe tool by grinding or line cutting, use lathe to process, can reach the purpose of crimping and shaping, but also Shortcomings: the one, the working face of instrument and part finished surface are sliding friction, easily cause crimping outer surface or shaping outer surface serious damage, affect the accessory appearance quality; In addition, the shape of working surface of instrument fixes, single, and because the difference of crimping size needs the crimping shaping tool of adapted corresponding size, versatility is poor, and for preventing that the part frictional heating is out of shape, the lathe rotating speed is extremely low during production, and production efficiency is low.
The utility model content
It is a kind of simple in structure, with short production cycle that the purpose of this utility model is to provide, the roll extrusion crimping shaping tool that manufacturing expense is low, reduce production costs, improve product quality and production efficiency simultaneously, the suitable especially tubular member crimping shaping processing to the many specifications of small lot.
The technical solution of the utility model is: a kind of roll extrusion crimping shaping tool, and roller is connected with the front end of knife bar by axle, and roller cooperates with shaft clearance.
Preferably, in the axial section of described roller, working face is semi-circular recesses or quadrant shape or linear.
Further, be provided with bearing between described roller and the axle.
Further, described knife bar is straight peen type or curved head type.
It is simple and reliable for structure that the utility model adopts, and utilizes existing engine lathe, can be to tubular member crimping machining or shaping.Roller working face and part work surface are rolling friction, and frictional force is little, be difficult for making part to produce and scratch and the heating distortion, and available higher rotation speed, thus improved production efficiency and product quality; According to the crimping size, only need to change the different size roller and get final product, saved input cost, enlarged the scope of application.The utility model is specially adapted to the production model of the tubular member crimping shaping processing of the many specifications of small lot.

Among the figure: 1-knife bar, 2-axle, 3-roller.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Such as Fig. 1, a kind of roll extrusion crimping shaping tool that the utility model provides, roller 3 is connected with the front end of knife bar 1 by axle 2, roller 3 and axle 2 matched in clearance.
Preferably, such as Fig. 2,3, in the axial section of roller 3, working face is semi-circular recesses or quadrant shape, can also be linear.According to the crimping shape, size, only need are changed the roller of different size type, can process such as Fig. 5,6,7, the part shown in 8 has been saved input cost, has enlarged the scope of application.
Further, be provided with bearing between roller 3 and the described axle 2.It is more smooth that roller 3 is rotated, and is particularly suitable for roll extrusion part inside and outside circle cylinder, finely tunes inside/outside diameter size, reduces the part ovality.
Further, such as Fig. 1, knife bar 1 is the straight peen type, is suitable for to such as Fig. 5 the part crimping shaping shown in 6,7.Such as Fig. 4, knife bar 1 is curved head type, more is suitable for as shown in Figure 8 part is carried out shaping, and the roll extrusion inner surface is revised size and dimension.
During production, the knife bar 1 of roll extrusion crimping shaping tool installed be clamped on the tool rest of engine lathe; Piece-holder to be processed is on the chuck of engine lathe; Start engine lathe, feed, deformation occurs in workpiece under the roll extrusion of roller 3, and when reaching technological requirement, withdrawing stops, and takes off the workpiece that processes, and installs next workpiece to be processed, enters next circulation.
It is simple and reliable for structure that the utility model adopts, and utilizes existing engine lathe, to tubular member crimping machining or shaping.Roller working face and part work surface are rolling friction, be difficult for making part to produce and scratch and the heating distortion, and available higher rotation speed, thus improved production efficiency and product quality; According to the crimping size, only need to change the different size roller and get final product, saved input cost.Be specially adapted to the production model of the tubular member crimping shaping processing of the many specifications of small lot.
Certainly; the utility model also can have other various embodiments; in the situation that does not deviate from the utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the utility model.
