Detailed Description

Embodiments of the technical scheme of the present utility model will be described in detail below with reference to the accompanying drawings. The following examples are only for more clearly illustrating the technical aspects of the present utility model, and thus are merely examples, and are not intended to limit the scope of the present utility model.

It is noted that unless otherwise indicated, technical or scientific terms used herein should be given the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

Embodiment one:

fig. 1 is a schematic structural view of a roller die according to a first embodiment of the present utility model; fig. 2 is a schematic structural diagram of a roll die monomer of a roll die according to an embodiment of the utility model. As shown in fig. 1 and 2, the roller die provided in the first embodiment includes at least one roller die unit 100, the roller die unit 100 includes a roller die holder 30 and a passive roller 20, the passive roller 20 is used for processing a wire, the passive roller 20 is connected with the roller die holder 30 through a roller shaft 10, the roller die holder 30 is provided with a blocking cover 40, and a vertical distance between an outer surface of the blocking cover 40 and the wire is greater than a diameter of the passive roller 20.

In general, in a wire drawing machine or a wire drawing machine, a roll die provided in front of each winding drum has two to six roll die units 100, and the adjacent roll die units 100 are alternately arranged horizontally and vertically with a roll axis 10 being perpendicular. In each roll die unit 100, two nominally parallel roll shafts 10 are typically provided, each roll shaft 10 being perforated with passive rolls 20 at approximately the middle.

In general, when reducing the wire rod, the passive roller 20 is stressed at the approximately middle position of the roller shaft 10, and the roller shaft 10 forms a mechanical structure with two ends supported and the middle stressed. In this structure, the roll shafts 10 are actually formed with a concave curve opening toward the intermediate position of the two roll shafts 10, and the concave curve is to cause a decrease in the accuracy of the position control of the roll shafts 10 by the passive rolls 20. To reduce the amount of deformation of each roll shaft 10, the distance between the roll holders 30 at both ends of the roll shaft 10 is generally compressed, thereby improving the stress condition.

However, since the distance between the die holders 30 at both ends of each roll shaft 10 is shortened, the vertical distance between the surface of the die holder 30, which faces away from the driven roll 20, and the running wire is significantly smaller than the diameter of the driven roll 20 of the adjacent sheet roll die unit 100. In this way, after the upstream passive roller 20 comes into contact with the lubricant that has fallen off the wire surface, it is possible to throw the lubricant to the outer surface of the roller die holder 30. After the wire drawing process has been completed over the last month, a lot of lubricant is accumulated on the outer surface of the die holder 30.

In this embodiment, four roll mold units 100 may be provided, and adjacent roll mold units 100 are disposed in such a manner that the roll axes 10 are perpendicular. Therefore, the four roll die units 100 are arranged in such a manner that the roll shafts 10 are alternately arranged in two directions. Each roll die unit 100 further comprises a frame 50, the frame 50 is located at the outermost side of each roll die unit 100, a roll die holder 30 is fixedly installed on the frame 50, a roll shaft 10 is installed on the roll die holder 30, and the roll shaft 10 is rotatably installed on a driven roll 20 through a rolling bearing 11.

In the passive roller 20, an annular inner flange 21 may be provided at one end of the hole of the passive roller 20, and two rolling bearings 11 may be disposed in the passive roller 20, wherein the outer ring of one rolling bearing 11 abuts against the annular inner flange 21, and the outer ring of the other rolling bearing 11 is restrained by a circlip 22 for hole. In particular, the rolling bearing 11 may be a deep groove ball bearing.

Specifically, the cover 40 may have a substantially rectangular or positive shape with a width corresponding to the thickness of the roll-form unit 100 and a length covering as much as possible the area between the two frames 50 of one roll-form unit 100.

In addition, in the present application, the expression that the roll shaft 10 is vertical is not limited to a plumb state, and because for some types of wire drawing machines, the upper surface of the frame of the wire drawing machine may be inclined to form an angle smaller than 10 degrees with the horizontal plane, the roll shaft 10 is vertical, which may mean that the roll shaft 10 also forms an angle smaller than 10 degrees with the plumb line. Further, since the direction of arrangement of the plurality of die units 100 is not necessarily along the longitudinal direction of the wire drawing machine in the roll shaft 10 in the horizontal state, the roll shaft 10 is not absolutely horizontal, and is, with a high probability, lower at the end closer to the operator than at the end farther from the operator. Thus, the roll axis 10 is horizontal in this application, and is not necessarily absolute, but may be oriented at a single digit angle to the horizontal.

By providing the blocking cover 40 on the outer side of the roller die holder 30, and the distance of the outer surface of the blocking cover 40 is greater than the diameter of the driven roller 20, it is possible to prevent the lubricant on the wire surface from being carried up by the driven roller 20 and falling onto the adjacent roller die holder 30, thereby preventing the lubricant from accumulating on the surface of the roller die holder 30 and avoiding potential safety hazards such as fire.

As shown in fig. 2, further, both ends of the roll shaft 10 are mounted to the roll die holder 30, and the roll die holder 30 is provided with blocking covers 40 at both ends of the roll shaft 10.

Of course, on both sides of the annular oil groove 31, sealing rings 32 are provided to seal the inner holes with the roll shaft 10 so as to prevent the lubricating oil from leaking therefrom.

In this embodiment, the positioning hole may be a stepped hole, and the positioning post 34 is matched with a larger section of the stepped hole. Taking the upper end roller die holder 30 of the vertical roller shaft 10 as an example, the first through hole, which is a smaller diameter section of the pressing oil cup passing through the stepped hole, is then screwed into the threaded hole in the positioning post 34 so as to communicate with the above-mentioned seat oil inlet hole 33.

By arranging the positioning column 34, the positioning accuracy of the retaining cover 40 and the roller die holder 30 can be improved by utilizing the matching of the positioning column 34 and the positioning hole, so that the accurate matching of the oil injection cup 60 and the threaded hole is facilitated.
