Description

In general, the zero line is repeatedly grounded (PEN) with the protective ground line (PE) at the neutral point (N) of the secondary side of the transformer, playing a double protection role.

[0003] In the processing of the zero line, in order to reduce the diameter of the zero line, improve the surface quality and improve the mechanical properties, the drawing equipment is usually applied to realize this function.

Long-time drawing operation will cause problems such as die surface wear, corrosion and pollution. If the die is not protected, it will affect the wire diameter and drawing accuracy of the zero line during drawing, reduce the stability and quality of the zero line drawing, and the existing drawing equipment is not convenient for surface treatment of the drawn zero line, which may cause corrosion to adhere to the surface of the zero line, thereby causing damage to the surface finish of the zero line.

[0027] Figures 1 to 9 An embodiment of the water tank type drawing device for double zero line drawing of the present application is shown.

[0028] In this optional embodiment, the water tank type drawing device for double zero line drawing includes a workbench 1, and a controller 2, a water tank 3, and a water pool 4 are arranged at the top end of the workbench 1; A plurality of groups of drawing assemblies 5 are arranged on one side of the water pool 4, and are used for drawing the zero line to the minimum line diameter specification; A protection box 6 is installed on the other side of the water pool 4; Two groups of quality control assemblies 7 are symmetrically installed in the interior of the protection box 6, and are used for cleaning the residual lubricant on the surface of the zero line, so as to avoid the attachment of the residual to the surface of the zero line and affect the quality of the zero line; Two groups of finished product winding assemblies 8 are symmetrically arranged on one side of the quality control assemblies 7, and realize the winding treatment of the drawn and controlled zero line; A plurality of groups of drawing die auxiliary assemblies 9 are installed in the interior of the water pool 4, and are matched with the drawing assemblies 5, so as to realize the drawing quality control in the drawing process of the zero line.

[0029] It needs to be explained that in the water tank type drawing equipment, the water tank 4 carries cooling liquid, which is usually mixed by water and a certain proportion of emulsified oil or lubricant. During the drawing process, a large amount of heat is generated due to deformation of the zero line. If effective cooling is not performed, overheating may cause unstable grain structure of the zero line. At the same time, the emulsified oil or lubricant in the cooling liquid forms a lubricating film during the drawing process, reducing the friction between the zero line and the die.

[0030] In one embodiment, for the above drawing assembly 5, an installation plate 501 is arranged on one side of the water tank 4. A placement groove 502 is formed in the middle of the installation plate 501. A rotating shaft 505 is arranged inside the placement groove 502. Two groups of to-be-drawn coils 506 are sleeved on the outside of the rotating shaft 505. A plurality of groups of drawing dies 507 are arranged inside the water tank 4. A guide wheel 503 is arranged on one side of the drawing die 507. Wire guide openings 504 are symmetrically arranged on both sides of the water tank 4. The drawing die 507 includes an abutment plate 5071 mounted in the drawing die auxiliary assembly 9. A die box 5072 is arranged at the top end of the abutment plate 5071. A drawing guide opening 5073 is formed in the inside of the die box 5072. The two ends of the drawing guide opening 5073 are arranged in a tapered structure. The diameter of the opening of the drawing guide opening 5073 is larger than the diameter of the middle part. The diameters of the middle parts of the plurality of groups of drawing guide openings 5073 decrease from large to small in turn. Therefore, by using a plurality of groups of die boxes 5072 with different drawing diameters, a larger entry angle can be used in the early stage to reduce the deformation resistance, and then the entry angle is reduced to control the uniformity of the wire flow and reduce the risk of brittle fracture of the zero line, so as to realize the purpose of stably drawing the zero line to the smallest wire diameter specification.

[0031] In one embodiment, for the above quality control assembly 7, the quality control assembly 7 includes two groups of support plates 701 mounted in the protection box 6. A rotating frame 702 is arranged on one side of the support plate 701. A plurality of groups of sliding cavities 703 are formed in the middle of the rotating frame 702. A connecting rod 704 is arranged inside the sliding cavity 703. An abutment block 705 is arranged in the middle of the connecting rod 704 and connected with the rotating frame 702. An abutment shaft 706 is arranged on one side of the connecting rod 704 and connected with the support plate 701. A cleaning brush 711 is arranged on the other side of the connecting rod 704. A protrusion 707 is arranged on one side of the rotating frame 702. A rotating block 708 is arranged at the top end of the protrusion 707. A threaded rod 709 is arranged inside the rotating block 708. A servo motor one 710 is arranged on one side of the threaded rod 709. A through hole 712 is formed in the middle of the rotating frame 702 and the support plate 701. The servo motor one 710 is mounted on one side of the support plate 701 through the mounting plate. Therefore, the lubricant and drawing debris remaining on the surface of the zero line after drawing can be wiped and treated, so as to avoid the attachment of the remaining substances on the surface of the zero line to corrode the zero line and form defects to affect the surface finish of the zero line and reduce the adverse effects in subsequent processing.

[0032] The working principle of the quality regulation assembly 7 is as follows: the drawn zero line is inserted through the through hole 712, the threaded rod 709 is driven to rotate by the servo motor 710, in the process of transmission, the rotating block 708 is driven to move, the rotating frame 702 is driven to move, the connecting block 705 inside the rotating frame 702 is driven to move, in the process of movement, the connecting rod 704 inside the connecting block 705 is moved, and the cleaning brush 711 at one end of the connecting rod 704 is contacted with the zero line, the lubricant and the drawing scraps remaining on the surface of the zero line are wiped and treated, and the spacing between the cleaning brushes 711 can be adjusted according to the diameter of the zero line, so that different cleaning requirements can be met, and the cleaning brush 711 and the connecting rod 704 are detachable structures.

[0033] In one embodiment, for the above-mentioned drawing die auxiliary assembly 9, the drawing die auxiliary assembly 9 comprises a clamping seat 901 installed in the water tank 4, the inside of the clamping seat 901 is provided with a sliding groove 902, and the inside of the sliding groove 902 is provided with an abutting block 903; the clamping seat 901 is provided with a connecting groove 904, the inside of the connecting groove 904 is provided with a rectangular sliding plate 905, and the top end of the rectangular sliding plate 905 is provided with a plurality of sets of calipers 906, and a clamping groove 907 is arranged between any two sets of calipers 906; the abutting block 903 comprises a fixed block 9031 installed in the sliding groove 902, the two sides of the fixed block 9031 are symmetrically provided with compression springs 9032, one side of the compression spring 9032 is provided with a push block 9033, and the bottom end of the push block 9033 is provided with a clamping block 9034; the height and length of the clamping block 9034 and the clamping groove 907 are the same, so that when the surface of the drawing die 507 is worn, corroded, contaminated and the like, the drawing die 507 can be disassembled, the drawing die 507 can be protected in the later period, the situation that the wire diameter, smoothness and drawing precision of the zero line are affected when the drawing die 507 is used continuously when worn is avoided, and the stability and quality of the zero line drawing are ensured.

[0034] The working principle of the drawing die auxiliary assembly 9 is as follows: when the drawing die 507 is installed and fixed, the push blocks 9033 are manually pressed, so that the two groups of push blocks 9033 move to the middle of the fixed block 9031 under the action of the compression spring 9032, and then the rectangular slide plate 905 is clamped into the inside of the connecting groove 904, and after the clamping is completed, the push blocks 9033 are released, so that the clamping blocks 9034 at the bottom of the push blocks 9033 are clamped into the inside of the clamping groove 907 at the top of the rectangular slide plate 905, and the fixing of the rectangular slide plate 905 is realized. Since the drawing die 507 is installed on one side of the rectangular slide plate 905, the fixing of the drawing die 507 is realized. When the drawing die 507 is abraded, corroded, contaminated and the like for a long time, the push blocks 9033 are manually pressed again, so that the two groups of push blocks 9033 move to the middle of the fixed block 9031 under the action of the compression spring 9032, and the clamping blocks 9034 are away from the clamping groove 907, so that the drawing die 507 can be removed.

[0035] In order to ensure the normal use of the drawing die auxiliary assembly 9, the water level of the lubricant liquid in the water tank 4 is lower than the installation height of the clamping seat 901, and the height of the L-shaped plate composed of the rectangular slide plate 905 and the abutment plate 5071 is less than the installation height of the clamping seat 901, so that the rectangular slide plate 905 is clamped into the inside of the connecting groove 904. In order to ensure the stability of the L-shaped plate composed of the rectangular slide plate 905 and the abutment plate 5071, the clamping position of the clamping block 9034 and the clamping groove 907 can be adjusted according to the actual situation.

[0036] As shown in Figure 5 The finished product winding assembly 8 includes a servo motor two 801 installed at the top of the protection box 6. The output shaft of the servo motor two 801 penetrates the protection box 6 and is provided with a winding roller 802. The bottom end of the winding roller 802 is provided with a limiting frame 803.

[0037] In order to facilitate the understanding of the above technical solutions of the present application, the working principle or operation mode of the present application in the actual process will be described in detail.

[0038] In actual application, the staff sets the to-be-drawn coil 506 on the outside of the rotating shaft 505, manually draws the zero line through the drawing assembly 5, performs surface treatment through the quality control assembly 7, and finally winds the finished product to the outside of the winding roller 802 as the zero line drawing starting point.

[0039] After winding is completed, the servo motor 801 is started to drive the take-up roller 802 to rotate. During the rotation, the neutral wire is pulled, so that the neutral wire sleeved on the outside of the coil to be pulled 506 passes through several sets of drawing dies 507 through the wire guide port 504 near the coil to be pulled 506. When the neutral wire passes through the drawing die 507, it is subjected to external force (traction force). Inside the drawing die 507, the neutral wire is subjected to axial tensile stress and radial compressive stress, and undergoes plastic deformation. Since the diameter of the drawing guide port 5073 inside the drawing die 507 is different, the neutral wire reaches the set wire diameter specification after multiple drawing.

[0040] Simultaneously, during the drawing process, an emulsion (or other lubricant) is added to the water tank 4 to form a lubricating film, reducing the friction between the drawing die 507 and the neutral wire. During the drawing process, the drawing die 507 generates a large amount of heat due to deformation. The coolant can prevent the material from overheating, annealing, or damaging the die. After the drawing is completed, the quality control component 7 is used to wipe the lubricant and drawing debris remaining on the surface of the neutral wire to prevent the residue from adhering to the surface of the neutral wire and corroding the neutral wire. Finally, the neutral wire, after drawing and cleaning, is wound onto the outside of the take-up roller 802 for easy processing later.

[0041] In summary, by utilizing the above-mentioned technical solutions of this invention, the invention has a simple structure and is easy to operate. By setting the drawing assembly 5, multiple sets of die boxes 5072 with different drawing diameters can be used to reduce deformation resistance in the early stage by using a larger entry angle. Subsequently, the entry angle is reduced to control the uniformity of wire flow and reduce the risk of brittle fracture of the neutral wire, thereby achieving the purpose of stably drawing the neutral wire to the minimum wire diameter specification. By setting the quality control assembly 7, this invention can wipe off the lubricant and drawing debris remaining on the surface of the neutral wire after drawing, preventing residues from adhering to the surface of the neutral wire and corroding it, forming defects that affect the surface smoothness of the neutral wire, and reducing adverse effects in subsequent processing. By setting the drawing die auxiliary assembly 9, this invention can disassemble the drawing die 507 when problems such as wear, corrosion, and contamination occur on the surface of the drawing die 507, facilitating the subsequent protective treatment of the drawing die 507, and preventing the drawing die 507 from continuing to be used when it is worn, which would affect the wire diameter, smoothness, and drawing accuracy of the neutral wire, thus ensuring the stability and quality of the neutral wire drawing.

[0042] This invention is not limited to the structures described above and shown in the accompanying drawings, and various modifications and changes can be made without departing from its scope. The scope of this invention is limited only by the appended claims.
