Description

Technical Field

[0001] The utility model relates to the field of wire rolling machines, in particular to a wire rolling machine for wire thread inserts. Background Technique

[0002] A wire thread insert, also known as a thread insert or simply an insert, is a spring-shaped concentric body with internal and external threads precisely processed from high-strength, high-precision, and smooth-surface cold-rolled diamond-shaped stainless steel wires. Generally, a wire rolling machine pulls the steel wire on the wire supply frame through a wire collecting device, so that the steel wire passes through the extrusion of the rollers on the wire rolling device, and the steel wire is rolled and formed, and the raw wire required for the wire thread insert can be produced.

[0003] In the production process of wire thread inserts, wire rolling is a crucial process, which determines the basic shape and performance of the inserts. Traditional wire rolling machines mostly use two wire rolling rollers with the same structure for extrusion. For example, the wire rolling machine for wire thread insert raw wire disclosed in the publication number CN214767784U includes a wire collecting component, a support component, a lower wire rolling roller, an upper adjustable wire rolling roller, and an adjustable support base. The support component includes a support table, and four support feet are provided at the four corners of the lower surface of the support table. An adjustable support base is provided on one side of the upper surface of the support table, and a lower wire rolling roller and an upper adjustable wire rolling roller are provided on the upper surface of the adjustable support base. The lower wire rolling roller and the upper adjustable wire rolling roller are corresponding up and down, and a wire collecting component is provided on the other side of the upper surface of the support table.

[0004] Since the structures of the two wire rolling rollers are the same, their extrusion effects on the steel wire are also the same, which makes it difficult to precisely control the deformation of the steel wire after extrusion, and it cannot be formed in one step during processing. After the steel wire is extruded by the two wire rolling rollers, although it can obtain a certain shape, it often needs subsequent processing and adjustment to meet the final requirements. This not only increases the production cost but also reduces the production efficiency. Content of the Utility Model

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model are clearly and completely described. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0019] Refer toFigures 1-5 , a wire rolling machine for wire thread inserts, comprising: a bracket 1, which provides a stable foundation for the entire wire rolling machine, ensuring stability and safety during the rolling process; a first wire rolling roll 2, mounted on the bracket 1, and a plurality of shaping grooves 201 linearly arrayed on the surface of the first wire rolling roll 2 are used to guide the rolling path of the wire; a second wire rolling roll 3, mounted on the bracket 1, located below the first wire rolling roll 2, and a plurality of shaping rings 301 linearly arrayed are connected to the surface of the second wire rolling roll 3. The shaping rings 301 are connected to the shaping grooves 201. When the first wire rolling roll 2 and the second wire rolling roll 3 rotate relatively, the shaping rings 301 and the shaping grooves 201 act together to roll the wire into a predetermined shape; two support parts 5, mounted on the bracket 1, are used to support the first wire rolling roll 2 and the second wire rolling roll 3, preventing the first wire rolling roll 2 and the second wire rolling roll 3 from displacing during the rolling process; the support part 5 includes: a support plate 501, mounted on the bracket 1; two support arms 502, one end of which is connected to the bracket 1 and the other end is connected to the support plate 501; a contact roll 503, connected to the support plate 501, and the contact roll 503 contacts the first wire rolling roll 2. The combination of the support plate 501 and the support arms 502 provides stable support for the first wire rolling roll 2 and the second wire rolling roll 3, preventing the displacement of the rolls during the rolling process, ensuring the stability and safety of the rolling process. Through the rotational contact of the contact roll 503 on the support plate 501, it will not affect the normal operation of the wire rolling rolls. The design of the first wire rolling roll 2 and the second wire rolling roll 3 allows the wire to be precisely rolled when passing through, ensuring the accuracy and consistency of the wire thread insert forming. The linear array distribution of the shaping grooves 201 and the shaping rings 301 can roll multiple wires simultaneously, and multiple shaping grooves 201 and shaping rings 301 can be set to different sizes, that is, wires of different sizes can be rolled. When the first wire rolling roll 2 and the second wire rolling roll 3 rotate relatively, the shaping grooves 201 and the shaping rings 301 act together to precisely roll the wire into a predetermined shape, realizing the efficient production of wire thread inserts.

[0020] Refer to Figure 1 and Figure 3, the driving part 4 is installed on the bracket 1 and is used to drive the first wire rolling roller 2 and the second wire rolling roller 3 to rotate in opposite directions; the driving part 4 includes: a power source 401 installed on the bracket 1, the power shaft of the power source 401 is connected to the first wire rolling roller 2 and is used to drive the first wire rolling roller 2 to rotate; two connecting rods 403, one end of each of the first wire rolling roller 2 and the second wire rolling roller 3 is connected with a connecting rod 403, and one end of each of the two connecting rods 403 penetrates through the bracket 1; two meshing gears 402 are arranged on one side of the bracket 1, one end of each of the two connecting rods 403 is respectively connected with the two gears 402, the direct connection between the power source 401 and the first wire rolling roller 2 ensures the direct transmission of the driving force, reduces the energy loss, and improves the working efficiency. The two meshing gears 402 realize the synchronous and opposite rotation of the first wire rolling roller 2 and the second wire rolling roller 3, ensuring the stability of the rolling process and the accuracy of the wire screw sleeve forming. The power source 401 can be a stepping motor or a servo motor.

[0021] Refer to Figure 4 and Figure 5 , the cross-sectional shape of the gap formed by the shaping groove 201 of the first wire rolling roller 2 and the shaping ring 301 of the second wire rolling roller 3 at the rolling contact is diamond-shaped to ensure the accuracy of the wire screw sleeve forming. The diamond-shaped cross-sectional shape of the gap ensures that the wire is subjected to uniform and accurate forces during the rolling process, improving the accuracy and consistency of the wire screw sleeve forming.

[0022] Refer to Figure 1 , the diameters of the two gears 402 are the same, and the centers of the two gears 402 are located on the same vertical line, ensuring the synchronous rotation of the first wire rolling roller 2 and the second wire rolling roller 3, and further improving the stability of the rolling process and the accuracy of the wire screw sleeve forming.

[0023] Refer to Figure 1 and Figure 2 , the lengths of the first wire rolling roller 2 and the second wire rolling roller 3 are the same and are both equal to the length of the support plate 501, and the length of the support plate 501 is the same as the lengths of the first wire rolling roller 2 and the second wire rolling roller 3, ensuring the comprehensiveness and effectiveness of the support.

[0024] During use, the steel wire is placed between the first wire rolling roller 2 and the second wire rolling roller 3. The power source 401 is turned on, and the power shaft directly drives the first wire rolling roller 2 to rotate. At the same time, through two connecting rods 403 and two meshing gears 402, the second wire rolling roller 3 is driven to rotate in the opposite direction. The support plate 501 and the support arm 502 in the support part 5 provide stable support for the first wire rolling roller 2 and the second wire rolling roller 3, ensuring the stability during the rolling process. As the first wire rolling roller 2 and the second wire rolling roller 3 rotate relatively, the steel wire is gradually guided into the gap between the shaping groove 201 and the shaping ring 301. The diamond-shaped cross-sectional gap shape ensures that the steel wire receives uniform and precise forces during the rolling process and is precisely rolled into a predetermined shape. Due to the linear array distribution of the shaping groove 201 and the shaping ring 301, the wire rolling machine can roll multiple steel wires simultaneously, and the rolled steel wires are continuously sent out.

[0025] In summary, compared with the prior art, the following beneficial effects are achieved: By using the cooperation of the shaping groove 201 and the shaping ring 301, the diamond-shaped gap cross-sectional shape formed at the rolling contact ensures that the steel wire receives uniform and precise forces during the rolling process, improving the accuracy and consistency of the steel wire screw sleeve forming and reducing the need for subsequent processing and adjustment. By precisely controlling the synchronous and opposite rotation of the first wire rolling roller 2 and the second wire rolling roller 3, the steel wire can obtain more uniform and consistent deformation during the rolling process, reducing the need for subsequent processing and adjustment. The support part 5 provides stable support for the first wire rolling roller 2 and the second wire rolling roller 3, preventing the displacement of the rollers during the rolling process and ensuring the stability and safety of the rolling process. By setting multiple shaping grooves 201 and shaping rings 301, multiple steel wires can be rolled simultaneously, improving the adaptability and flexibility of the equipment, and the wire rolling machine can adapt to the production requirements of steel wire screw sleeves with different specifications and quantities.
