Each wire drawing unit is composed of an eye mould assembly, a traction wheel 12, a wire divider assembly, a tension control assembly and the like which are arranged in a longitudinal row. Because the three parts are independently arranged and the wire drawing units of the wire drawing part are arranged in a row, the occupied area is large. For fine wire drawing manufacture of metal with high cleanliness requirement, a slip-free wire drawing machine is usually installed in a constant-temperature dust-free room, and the constant-temperature dust-free room is very sensitive to the occupied area of equipment due to high decoration and operation cost.
The floor area of the existing slip-free wire drawing machine greatly increases the running cost. Meanwhile, the existing slip-free wire drawing machine is arranged in sequence from paying-off, wire drawing and wire collecting, all wire drawing units in the wire drawing part are arranged in a serial single row, wire drawing operation starts from the paying-off part, metal wires are successively thinned through the wire drawing part, and finally the drawn wires are collected through the wire collecting part, so that the distance in the whole process is long, and the operation is not facilitated. Especially, with the increase of labor cost, an operator usually manages several non-slip wire drawing machines at the same time, and the existing non-slip wire drawing layout increases the labor intensity of the operator for managing the non-slip wire drawing machines.
As shown in fig. 2-4, the wire drawing units of the wire drawing part of the existing non-slip wire drawing machine also have an eye die outlet guide wheel 18 for guiding at the outlet of the eye die, namely between the traction wheel 12 and the eye die 4, and excessive guide wheels not only increase maintenance and use costs but also reduce the operational reliability of the equipment. The existing wire 5 of the non-slip wire drawing machine comes out from the eye die outlet guide wheel 18, winds to the traction wheel 12 and the wire divider wheel 14, adjusts the included angle between the axial lead of the wire divider wheel 14 and the axial lead of the traction wheel 12 through the adjustable wire divider seat 13, so that a certain interval P is generated between the centers of the wound wires, the winding circle number is N, the vertical plane of the center of the V-shaped groove of the tension rod guide wheel 16 and the vertical plane Ai of the center of the hole of the eye die 4 are outwards deviated by a distance L=P in the X direction, the centers of the holes of the eye die 4, the guide V-shaped groove of the eye die inlet guide wheel 11 and the guide V-shaped groove center of the eye die outlet guide wheel 18 of all the existing non-slip wire drawing units are all on the same vertical plane, namely the vertical plane ai+1 is coplanar with the vertical plane Ai, the moving track of the wire 5 between the tension rod guide wheel 16 of the wire drawing machine to the next stage eye die inlet guide wheel 11 forms an included angle Sta with the vertical plane, the wire possibly contacts the inner side surface of the V-shaped groove of the tension rod guide wheel 16 and the guide groove inner side surface of the eye die inlet guide wheel 11 in the moving process, and the wire quality is easy to be influenced when the wire surface of the wire is not broken, and the wire is easy to be broken.

The wire takeup portion 3 of this embodiment is arranged above the wire paying-out portion 2 and on the right side of the machine, the lower layer wire threading is from right to left, the upper layer wire threading is from left to right, and similarly the wire takeup portion 3 may be arranged above the wire paying-out portion 2 and on the left side of the machine, the lower layer wire threading is from left to right, and the upper layer wire threading is from right to left.
In some embodiments, the take-up part 3 and the pay-off part 2 may be disposed on two sides of the wire drawing part 1, respectively, and the wire drawing part 1 may be changed into an upper-lower layered structure. The wire takeup section 3, the wire drawing section 1 and the wire paying-off section 2 may be designed as a whole, or may be designed as a separate structure. The wire drawing part 1 can be used as a modularized design, for example, 3 wire drawing units on the upper part and the lower part form a wire drawing module with 6 wire drawing units, and 2 wire drawing units are combined into 1 wire drawing part 1 with 12 wire drawing units according to the requirement, and the description is omitted.
The traditional installation of the eye die outlet guide wheel 18 has strict requirements in the X direction and the Z direction, the eye die inlet guide wheel 11 is guided to the upper edge of the V-shaped groove center, the hole center of the eye die 4 and the upper edge of the V-shaped groove center of the eye die outlet guide wheel 18 are controlled to be on the same straight line, and the requirements on processing and assembling precision are very high. According to the invention, by changing the structures of the eye die assembly, the traction wheel 12 and the deconcentrator assembly and redesigning the relative positions, the metal wire 5 is automatically adjusted to an optimal position in the X direction under the action of traction and tension, the automatic adjustment of the wire drawing position improves the wire drawing state, the quality of the wire drawing surface is improved, and the wire breakage rate is reduced.
The existing slip-free wire drawing machine has the problem that the moving track of the metal wire from the tension rod guide wheel 16 of the wire drawing machine to the inlet guide wheel 11 of the next stage eye mould forms an included angle Sta with the vertical plane due to the existence of the offset distance L, and the included angle enables the metal wire to contact the tension rod guide wheel 16 and the inlet guide wheel 11 of the eye mould to guide the side surface of the V-shaped groove in the moving process, so that the surface quality of the metal wire is affected and the risk of wire breakage is increased. As shown in fig. 3 and 4, TAN (Sta) =l/Ld, in order to minimize the included angle Sta, the conventional slip-free wire drawing machine employs increasing the distance (Ld) between the tension bar guide 16 and the next-stage eye-entrance guide 11 to reduce the included angle Sta. The die assembly, traction wheel 12 and wire divider assembly of each wire drawing unit, the tension control assembly is arranged in a column to maximize the distance (Ld) between the tension rod guide wheel 16 and the next stage die entrance guide wheel 11. If the existing structure is directly changed into an upper layer arrangement and a lower layer arrangement, the height of the whole machine is too high to be beneficial to operation. To arrange the drawing units in layers requires the longitudinal (Z-direction) distance of the compression drawing units, i.e. the distance between the tension rod guide wheel 16 and the inlet guide wheel 11 of the next stage eye mould is reduced, and the included angle Sta is increased by adopting the existing structure. To solve this problem, the present invention designs the interval P between the wire centers on the traction wheel and the number of windings N such that the distance between the first winding wire center on the traction wheel 12 coming out of the eye die and the wire center coming into the tension bar guide wheel 16 is l=p×n, the wire enters the tension bar guide wheel 16 in the tension unit through the traction wheel 12 and the splitter wheel 14, comes out of the tension bar guide wheel 16 into the eye die inlet guide wheel 11 of the next stage wire drawing unit, the tension bar guide wheel 16 of each wire drawing unit is offset outwardly in the X direction by a distance L from the vertical plane in which the eye die inlet guide wheel 11 of the next stage wire drawing unit is directed to the V-groove center and the eye die 4 hole center is located by a distance L from the vertical plane in which the eye die inlet guide wheel 11 of the previous wire drawing unit is directed to the V-groove center and the eye die 4 hole center is located, i.e., the tension bar guide wheel 16 of the previous stage wire drawing unit is offset outwardly in the X direction by a distance L from the vertical plane in which the eye die inlet guide wheel 11 of the next stage wire drawing unit is directed to the V-groove center and the eye die 4 hole center is located. In theory, the included angle STA is zero, and the distance (Ld) between the tension rod guide wheel 16 and the entrance guide wheel 11 of the next-stage eye mold cannot influence the size of the included angle STA. The invention changes the eye mould components, the traction wheel 12 and the wire divider components which are adopted by the existing wire drawing unit of the non-slip wire drawing machine, and the tension control components are in a structure of being arranged in a column, and the purpose of reducing the occupied area is achieved by moving the traction wheel 12 and the wire divider components to the position parallel to the eye mould components and directly winding the metal wire on the traction wheel 12 and the wire divider wheels 14 through the eye mould, so that the eye mould components, the traction wheel 12 and the wire divider components are arranged in series, and the tension control components are arranged below, thereby shortening the upper and lower sizes of the wire drawing unit, realizing layered arrangement of the wire drawing unit and achieving the purpose of reducing the occupied area. The wire drawing units of each group are arranged in a stacked manner in the X direction so that the included angle Sta approaches zero, and the metal wires cannot contact the tension rod guide wheel 16 and the eye mould inlet guide wheel 11 to guide the side surfaces of the V-shaped grooves in the moving process, so that the surface quality of the metal wires is improved, and the wire breakage condition is reduced.
As shown in fig. 5 and 6, the present embodiment is exemplified by a slip-free wire drawing machine of 10 eye molds 4, and can be designed as a slip-free wire drawing machine of any single or double eye molds 4.
The wire drawing machine of this embodiment may also be designed in a modularized manner, for example, wire drawing units arranged in layers up and down are designed to form wire drawing modules having n wire drawing units, and m such modules are combined into a wire drawing portion 1 having n×m wire drawing units, where n, m are any integer.
It should be noted that, this embodiment describes the wire drawing machine with a two-layer structure in detail, and is also suitable for three-layer and four-layer structures.
The foregoing examples are set forth in order to provide a more thorough description of the present application and are not intended to limit the scope of the application, and various modifications of the application, which are equivalent to those skilled in the art upon reading the present application, will fall within the scope of the application as defined in the appended claims.
