Technical Field
[0001] The utility model relates to the field of cold heading equipment, in particular to a cold heading machine. Background Art
[0002] In modern industrial production, cold heading machines, as an important metalworking equipment, play a key role in manufacturing various fasteners and special-shaped parts. Traditional cold heading machines typically use a conveyor structure to gradually guide the coiled steel wire to the feed port, and then transfer it to the cold heading machine for processing.
[0003] However, traditional cold heading machines have significant shortcomings in practical applications. Since steel wires often vary in thickness, and the feed openings of traditional cold heading machines are typically fixed in size, this leads to a series of problems when processing wires of varying thicknesses. On the one hand, thinner wires may wobble at the feed opening, affecting the stability and accuracy of the feed, and thus the quality of the cold heading process. On the other hand, thicker wires may not be able to enter the feed opening smoothly, requiring tedious adjustments and possibly even replacement of equipment or accessories, which not only increases production costs but also reduces production efficiency.
[0004] To solve the problem of traditional cold heading machines processing steel wires of different thicknesses, this utility model proposes a design with an adjustable structure at the inlet of the cold heading machine. Through this design, the size of the feed port can be flexibly adjusted according to the thickness of the steel wire, ensuring that the steel wire can smoothly enter the cold heading machine for processing.

A limiting end plate restricts the telescopic structure from always moving within the adjusting port. This design can flexibly adjust the size of the feed port according to the feeding requirements of steel wires of different thicknesses, ensuring that the steel wires can enter the processing smoothly.

[0035] The present invention is described in further detail below with reference to the accompanying drawings.
[0036] The following description is intended to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are for illustrative purposes only, and those skilled in the art will readily appreciate other obvious variations. The basic principles of the present invention as defined in the following description may be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.
[0037] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "transverse", "up", "down", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like to indicate directions or positions are based on the directions or positional relationships shown in the accompanying drawings, which are merely simplified descriptions for the convenience of describing the present invention, and do not indicate or imply that the device or component referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, the above terms should not be understood as limitations on the present invention.
[0038] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity. Example
[0039] See also Figure 1 - Figure 11 A cold heading machine comprises a cold heading machine body 1 provided with a feed machine port 101, an adjusting port 2 is provided at the inlet of the feed machine port 101, and a retractable telescopic structure 4 is provided all around the inside of the adjusting port 2. A ball holder is provided at one end of the telescopic structure 4, and a rolling ball 3 is rotatably connected in the ball holder. The other end of the telescopic structure 4 passes through the adjusting port 2 and is connected to a limiting end plate 402 for limiting position. A reset spring 401 is provided between the adjusting port 2 and the telescopic structure 4 for resetting.
[0040] The cold heading machine of the present application is mainly composed of a cold heading machine body 1 and a feed machine port 101 and other structures. The feed machine port 101 is installed on the cold heading machine body 1, and its opening size is always kept at the maximum value to facilitate the entry of subsequent steel wires. At this time, an adjusting port 2 is added to the front end of the feed machine port 101 installed on the cold heading machine body 1, and the stabilizing port 201 opened around the inside of the adjusting port 2 accommodates a retractable telescopic structure 4. A ball holder is provided at one end of the telescopic structure 4 to connect the rolling ball 3 to reduce the friction when the steel wire passes through. The reset spring 401 between the telescopic structure 4 and the adjusting port 2 can provide a reset force when the telescopic structure 4 is extended and retracted due to changes in the thickness of the steel wire. The limiting end plate 402 limits the telescopic structure 4 to always move in the adjusting port 2. This design can flexibly adjust the size of the feed port according to the feeding requirements of steel wires of different thicknesses to ensure that the steel wire enters the processing smoothly.
[0041] It should also be noted that when steel wires of different thicknesses are guided to the feed port 101 on the cold heading machine body 1 through the adjusting port 2, they first contact the guide tube port 5, and the guide tube port 5 guides the steel wire to the inside of the adjusting port 2. If the steel wire is thinner, the steel wire will contact the rolling ball 3 when entering the adjusting port 2. Since the diameter of the steel wire is small, the pressure on the rolling ball 3 is small, and the reset force of the reset spring 401 will cause the telescopic structure 4 to shrink inward. At this time, the rolling ball 3 rotates in the ball holder of the telescopic structure 4, reducing the friction between the steel wire and the inner wall of the adjusting port 2, ensuring that the steel wire can smoothly pass through the feed port 101 and enter the cold heading machine for processing; if the steel wire is thicker, the steel wire will generate greater pressure on the rolling ball 3 when entering the adjusting port 2, pushing the telescopic structure 4 to extend to the outside of the adjusting port 2. At this time, the reset spring 401 is compressed, providing a reaction force for the telescopic structure 4.
[0042] The guide tube opening 5 is designed to be open, so that the incoming steel wire can be guided more conveniently.
[0043] The present application also provides a stabilizing opening 201, which is evenly opened around the inside of the regulating opening 2, so that the telescopic structure 4 can move therein when telescoping, thereby limiting the telescopic structure 4 in motion and ensuring its stability during the activity.
[0044] A connecting screw 403 is also provided in the present application. After the telescopic structure 4 passes through the stabilizing opening 201, it is connected to the limiting end plate 402 through the connecting screw 403. One end of the connecting screw 403 is connected to the limiting end plate 402, and the other end is connected to the telescopic structure 4 through threaded rotation, thereby facilitating disassembly and assembly.
[0045] A protective convex pad 404 is also provided in the present application. The protective convex pad 404 is glued to the inner circle of the limiting end plate 402. The protective convex pad 404 is elastic and made of rubber. When the telescopic structure 4 is in a stationary state and the limiting end plate 402 is outside the adjustment port 2, the protective convex pad 404 fits the outer wall of the adjustment port 2. When the telescopic structure 4 drives the limiting end plate 402 to expand and contract outside the adjustment port 2, the protective convex pad 404 will separate from the outer wall of the adjustment port 2. The design of this protective convex pad 404 can protect the contact surface when it is touched again.
[0046] This application also provides a built-in annular groove 102, a threaded connection tube 2012 and a protective ring 2013. A limiting ring 2011 is provided at one end of the regulating port 2 facing the feeder port 101. The limiting ring 2011 and the threaded connection tube 2012 are an integrated structural design. The threaded connection tube 2012 is threadedly connected to the built-in annular groove 102 opened at the inner ring mouth of the feeder port 101, thereby realizing a firm connection between the regulating port 2 and the feeder port 101.
[0047] It should also be noted that the inner diameter of the protection ring 2013 is designed to be equal to the inner diameter of the feeder port 101. This design prevents obstruction when the steel wire material enters and improves the smoothness of feeding.
[0048] The present application also provides a protective ring 2013 and a positioning plug-in 2014. The protective ring 2013 is provided on the contact surface between the threaded connection tube 2012 and the built-in annular groove 102. The threaded connection tube 2012 and the protective ring 2013 are connected by the positioning plug-in 2014, wherein one end of the positioning plug-in 2014 is connected to the circle mouth of the threaded connection tube 2012, and the other end can be inserted into the inside of the protective ring 2013. The insertion end of the positioning plug-in 2014 is constructed in a spike state to ensure the stability of the connection. This connection method can timely disassemble and assemble the protective ring 2013 according to the use requirements. At the same time, the protective ring 2013 is designed for rubber material. When the threaded connection tube 2012 is rotated to connect to the inside of the built-in annular groove 102 and generate a force with its inner wall, the design of the protective ring 2013 can increase the friction of the contact surface to prevent loosening between the adjustment port 2 and the feeder port 101 during the cold heading process.
[0049] In this application, an inner concave ring opening 202 is also provided, and the inner concave ring opening 202 is respectively opened at the barrel openings at both ends of the adjusting port 2. The inner concave ring opening 202 at one end of the adjusting port 2 facilitates the guide barrel opening 5 to be connected therein by threaded rotation, while the inner concave ring opening 202 at the other end enables the limit ring 2011 to be connected to one end of the threaded connection barrel 2012 away from the threaded connection barrel 2012 by threaded rotation. The various parts cooperate with each other to achieve convenience in assembly, and the adjusting port 2 and the guide barrel opening 5 can be assembled according to usage requirements.
