DETAILED DESCRIPTION

[0032] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0033] Reference Figures 1 to 10The utility model provides a two roll roll die, include: frame 1, roller seat 2 and outer frame body 3, roller seat 2 has two, symmetry setting in frame 1, and roller seat 2 has inner frame body 21, the roller 22 with bearing 23 of two ends is arranged in this inner frame body 21, inner frame body 21 still is provided with the gasket 24 for pressing the bearing 23, wherein, the installation cavity 25 is arranged in the inner frame body 21, the installation cavity 25 is by middle cavity 251, upper cavity 252 and lower cavity 253 constitute, the roller 22 is set in the middle cavity 251, and the bearing 23 of sleeve setting in the both ends of roller 22 is located in upper cavity 252 and lower cavity 253 respectively. The bearing 23 can select tapered roller bearing in the embodiment, makes the roller 22 reduce friction in the rotation process, improves the production efficiency of mechanism, and prolongs the service life. Wherein, the inner ring of tapered roller bearing is towards the direction of roller 22, and its outer ring is towards the outside, that is, contact with gasket 24. And the design of multicavity provides better structural support, helps to bear greater load, reduces the collision and interference between parts, wherein, upper cavity 252 and lower cavity 253 can also be guide groove, avoid the vibration or inclination of tapered roller bearing in the movement process, influence its rotation stability.

[0034] In addition, the outer frame body 3 is arranged on the outer surface of the inner frame body 21, and is composed of a bottom plate 33, a side plate 31 and a top plate 32. The top plate 32 is pressed on the gasket 24 by an adjusting component and is transmitted to the bearing 23 and the roller 22, so that the two roller seats 2 are kept in the same straight line. The adjusting component is a fastener, which can be a screw. By screwing the screw, the top plate 32 is tightly pressed on the gasket 24. The gasket 24 under the force is transmitted to the bearing 23 to adjust the position of the bearing 23. The bearing 23 at the other end is also passively adjusted in position. In other words, the end with the adjusting component is the pressed end, and the other end is the fixed end. As long as the pressed end is adjusted, the fixed end is adjusted with the pressed end. The position of the roller 22 and the bearing 23 is accurately adjusted, the center lines of the two rollers are kept in the same horizontal line, the up and down bouncing of the roller 22 during processing is avoided, the symmetry of the two roller seats 2 is realized, the position of the two roller seats 2 always meets the process requirements, and the processing of the wire rod is facilitated.

[0035] In some embodiments, the adjusting component comprises a guide column 5 arranged between the side plate 31 and the inner frame 1, and a first spring 6 and a top plate 32 are arranged on the guide column 5, and the top plate 32 is pushed to press on the cushion block 24 by the first spring 6. The elasticity of the first spring 6 enables the top plate 32 to adaptively adjust the pressure and better press on the cushion block 24, thereby improving the supporting effect on the cushion block 24 and the bearing 23, and reducing the possibility of the two roller seats 2 not being in the same straight line and the up-and-down jumping of the roller 22 or the instability of the roller 22 in the processing process. The guide column 5 provides stable guidance for the top plate 32 to ensure the accuracy of the movement track. Compared with the cooperation of the top plate 32 and the screw, the operation of the worker is more convenient and fast.

[0036] In some embodiments, the adjusting component further comprises a groove 4 arranged on the top surface of the inner frame 21, the groove 4 is composed of an inclined groove 41 and a bottom groove 42, a guide rail 8 is adapted to the groove 4, and the top plate 32 cooperates with the guide rail 8 through a sliding piece 7, and when the sliding piece 7 moves along the guide rail 8, the top plate 32 presses on the cushion block 24.

[0037] The guide rail 8 is composed of an upper rail 81 arranged on the top surface of the inner frame 21, an inclined rail 82 adapted to the inclined groove 41, and a lower rail 83 adapted to the bottom groove 42. The upper rail 81, the inclined rail 82, and the bottom rail are all arranged as T-shaped grooves 84. The sliding piece 7 is a pair of groups, which comprises a fixed seat 71 arranged on the lower surface of the top plate 32, and a rotatable roller 72 arranged on the fixed seat 71 and cooperated with the T-shaped groove 84.

[0038] Firstly, the cooperation of the roller 72 and the T-shaped groove 84 reduces the friction with the groove and improves the smoothness during sliding, so that the top plate 32 can more easily move along the groove in the guide rail 8. The guide rail 8 is designed in three sections, or provides multiple guidance, which not only ensures the stability of the top plate 32 during movement, but also slowly increases the force applied to the cushion block 24 as the top plate 32 continuously moves in the inclined rail 82 after moving from the upper rail 81 to the inclined rail 82. At the same time, when moving from the inclined rail 82 to the lower rail 83, the force applied to the cushion block 24 tends to be stable. When the roller 72 cannot move in the lower rail 83, the movement of the top plate 32 is completed. Compared with adjusting the top plate 32 by screw, it is more time-saving and labor-saving, and the operation is simple.

[0039] In addition, the side plate 31 comprises a lower plate 312 and an upper plate 311 arranged in the lower plate 312 and having elasticity. After the top plate 32 completely covers the cushion block 24, the upper plate 311 pops up from the lower plate 312 to limit the movement of the top plate 32. Specifically, the lower plate 312 is provided with a mounting groove 313, and the mounting groove 313 is provided with a second spring 314 connected with the upper plate 311.

[0040] When the top plate 32 moves to the end, the upper plate 311 abutting against the lower surface of the top plate 32 is immediately moved upward by the force generated by the second spring 314 after being separated from the top plate 32, so as to limit the movement of the top plate 32 in the guide rail 8, thereby realizing the locking function of the top plate 32. When replacing or maintaining, the top plate 32 can be moved back by pressing the upper plate 311 into the mounting groove 313 or moving the upper plate 311 below the top plate 32. The accurate adjustment of the position of the roller 22 bearing 23 is realized, and it is ensured that the center lines of the roller surfaces of the two rollers are on the same horizontal line, so as to effectively avoid the up-and-down jumping of the roller 22 in the processing process, thereby improving the processing quality and the production efficiency.

[0041] The above description of disclosed embodiments enables those skilled in the art to make or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to these embodiments shown herein, but will accord with the widest scope consistent with the principles and novel features disclosed herein.
