Abstract
The utility model relates to an improvement on a bar bending tool. The tool comprises a reference plate and pins, wherein control holes are uniformly formed on the reference plate; the diameters of the pins correspond to those of the control holes; and the pins are placed in the control holes. The utility model has the advantages and effects that compared with the conventional bar bending methods, especially the bending method utilizing pressing dies, the novel bar bending tool can reduce the manufacturing cost of auxiliary tools, is particularly suitable for bar bending without great change in size, and has multiple purposes; and the novel bar bending tool can also reduce labor intensity, be used for bending various bars simultaneously, reduce production preparation time of workers, and improve production and manufacture efficiency. In addition, the bar bending tool improves the bending technique, simplifies technique process, and accommodates to the prevailing development of bar bending.
Description
Technical field
The utility model belongs to mechanical manufacturing field, relates to the curved instrument of a kind of bar.
Background technology
The field of common mechanical manufacturing now is curved to bar mainly to be to adopt to make one group of pressing mold earlier as curved instrument, the bar that needs are curved is positioned in the pressing mold then, and the working pressure machine presses the bar profile, but it is inconsistent that the curved size of bar is made in general present requirement, need the curved necessary corresponding one group of pressing mold of making of bar at every turn, manufacturing cycle is long, complicate fabrication process, and must use specific purpose tool curved.
Summary of the invention
The purpose of this utility model provides short, the curved instrument of the simple bar of manufacture process of a kind of manufacturing cycle.Technical solution of the present utility model is, instrument is made up of datum plate, pin, evenly has control hole on the datum plate, and the diameter of pin is corresponding with control hole, and pin places control hole.Advantage that the utlity model has and effect, the utility model and the curved means of current bar mainly are to use the curved contrast of pressing mold, use the utility model can reduce the aid manufacturing cost, it is curved to be specially adapted to the little bar of change in size, can the multiple function of curved instrument.Alleviate labor strength.Can multiple bar curved together, reduce the workman and produce time, improve and manufacture efficient.Improve curved process means, saved the producing cost of a large amount of aids, simplified technological process, adapted to the curved development of current bar.
Description of drawings
Fig. 1 is a curved schematic diagram of the present utility model.
The specific embodiment
Instrument is made up of datum plate 1, pin 2, evenly has control hole 3 on the datum plate 1, and the diameter of pin 2 is corresponding with control hole 3, and pin 2 places control hole 3.
According to the curved control point control appearance and size of bar, need not control whole bar profile as pressing mold, saved unnecessary location structure, only need on datum plate, make a part of control hole, come just form factor of conversion control rod by changing the pin position, according to each position, hole of the curved size system of bar, on a datum plate, the bar location can be bent the bar of various different sizes.
When using the utility model, can according to the shape of curved material, pin 2 is inserted in the control hole 3 of curved position, by changing the position that pin 2 inserts corresponding control hole 3, control bar 4 curved corners, change curved shape fast, adapt to the curved function of different bars.
