Description

Technical Field

[0001] The utility model relates to the technical field of screw processing, in particular to a screw wire drawing machine. Background Art

[0002] Screws in sewing machines are used to assemble and adjust the needle plate, presser foot, thread wheel, thread bar and other parts of the sewing machine to fix and adjust the various parts of the machine to ensure that the machine can work normally. Screw processing usually involves steps such as material collection, pretreatment, wire drawing, cold heading and cutting. Screw wire drawing machine is a part of screw processing and forming. It is usually used to continuously extrude and stretch metal bars or wires through a mold to make screw wires or threaded rods with smaller diameters.

[0003] The process of screw wire drawing makes the screw wire thinner through the matching die hole, but long-term wire drawing causes the temperature of the die hole to rise and causes great wear on the die hole. Therefore, the die needs to be replaced or repaired frequently, which increases the maintenance cost and downtime of the equipment. For this reason, we propose a screw wire drawing machine to solve the existing problems. Utility Model Content

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] like Figure 1-Figure 5 As shown, a screw wire drawing machine proposed by the utility model comprises a processing box 1, a cleaning box 4, a mounting cover 10, a sleeve 11 and a turntable 12. The cleaning box 4 is arranged on one side of the processing box 1, and the turntable 12 is arranged inside the processing box 1. A gear ring 15 is sleeved on one end of the turntable 12. The turntable 12 is provided with mold holes 14 with equidistant distribution and different apertures. A motor 16 is arranged on one side of the turntable 12, and a gear 17 meshing with the gear ring 15 is arranged at the output end of the motor 16.

[0023] A base 2 is provided at the lower end of the processing box 1 and the cleaning box 4;

[0024] A plurality of guide wheels 7 are arranged inside the cleaning box 4;

[0025] A guide wheel 2 3 is provided inside one side of the processing box 1, and the guide wheel 2 3 is higher than the guide wheel 1 7 and the guide wheel 2 3;

[0026] A sleeve ring 8 is provided on one side of the guide wheel 2 3, and a rubber scraper ring 13 is provided on the inner wall of the sleeve ring 8. The rubber scraper ring 13 is located on one side of the guide wheel 2 3;

[0027] The processing box 1 is provided with symmetrically distributed bearing brackets 18, and both ends of the turntable 12 are rotatably mounted inside the bearing brackets 18;

[0028] Based on the implementation steps of Example 1: the motor 16 drives the gear ring 17 to push the gear ring 15, driving the turntable 12 to rotate. When the turntable 12 rotates, the position of the die holes 14 with different apertures is adjusted, and the screw wire is guided by the guide wheel 7 and enters the corresponding die hole 14. The aperture inside the die hole 14 is smaller than the specification of the wire, so that the wire passing through the die hole 14 is drawn into a small-sized wire. During the drawing process, the wire and the die hole 14 are located in the cooling lubricant inside the processing box 1, and the die hole 14 and the wire are lubricated and cooled;

[0029] The wire after drawing is guided by the guide wheel 23. When the wire is lifted, the liquid material adhered to the outer wall partially slides down. When passing through the rubber scraper ring 13, most of the liquid material on the outer wall of the wire is scraped off. When the large-sized wire passes through, the rubber material is squeezed, and the inner diameter of the rubber scraper ring 13 is squeezed and expanded accordingly, so that different wires are effectively scraped, and the cooling lubricating liquid is recycled, which avoids the dripping of liquid material on the outer wall during the wire transportation process, causing the processing environment and equipment to be polluted, and is beneficial to the subsequent processing of the wire.

[0030] like Figure 1-Figure 5 As shown, compared with the first embodiment, the screw wire drawing machine proposed by the utility model further includes: a water pump 5 and a hot air blower 6 are arranged at the front end of the cleaning box 4, a sleeve 11 and a mounting cover 10 are arranged inside the cleaning box 4, an annular tube 25 is arranged inside the sleeve 11, and nozzles 19 distributed in an annular array are arranged on the inner wall of the annular tube 25, and an annular air groove 22 in an annular shape is opened inside the mounting cover 10;

[0031] Two sets of guide wheels 9 are arranged inside the cleaning box 4;

[0032] The output end of the water pump 5 is provided with a water supply pipe 23 penetrating the annular pipe 25, and the output end of the hot air blower 6 is provided with an air supply pipe 24 penetrating the mounting cover 10;

[0033] A second collar 20 is provided between the sleeve 11 and the mounting cover 10, and a second rubber scraper ring 21 is provided on the inner wall of the second collar 20;

[0034] In this embodiment, although most of the cooling lubricant on the outer wall of the wire is scraped off, there is still a layer of liquid film passing through the sleeve 11, and the water pump 5 sucks the corresponding dissolving cleaning liquid, and transports it to the inside of the annular tube 25 through the water pipe, and acts on the wire through the nozzle 19 to dissolve and clean the liquid film;

[0035] When the wire passes through the rubber scraper ring 21, the residual liquid on the outer wall of the wire after cleaning is scraped off, but a layer of liquid film will still be formed. When passing through the installation cover 10, the hot air blower 6 is operated to transport the hot air flow to the inside of the installation cover 10 through the air supply pipe 24, and act on the outer wall of the wire through the annular air groove 22 to dry the wire, thereby ensuring the cleanliness of the wire and facilitating subsequent processing.

[0036] The above-mentioned specific embodiments are only several preferred embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.

[0037] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
