Description

Technical Field

[0001] The utility model relates to the technical field of screw equipment, in particular to a cold heading machine for screw processing. Background Art

[0002] A cold heading machine is a device specifically used for mass-producing fasteners such as screws. It applies pressure to a metal blank at room temperature to cause plastic deformation in a die cavity, thereby forming it into a specified shape and size.

[0003] Moreover, the existing multi-station automated production can complete the entire production process from roller feeding, cutting, corner pressing, punching to forming, which can effectively improve production efficiency. For example, the Chinese utility model patent with the publication number CN210936936U: Cold Heading Machine. In this application, the feeding assembly includes a driving feeding wheel and a driven feeding wheel, and the driving feeding wheel and the driven feeding wheel are arranged vertically on the frame and are rotationally matched with the frame through a wheel shaft. The space between the driving feeding wheel and the driven feeding wheel serves as a feeding gap for extruding and feeding strip-shaped raw materials. Therefore, when the driving feeding wheel and the driven feeding wheel are used to convey raw materials such as steel wires, they extrude and convey the steel wires and other raw materials with each other. When extruding and conveying steel wires or raw materials with different diameters, since grooves are provided on the outer sides of the driving feeding wheel and the driven feeding wheel, a guiding conveyance of the steel wires and other raw materials is achieved. Therefore, after the outer sides of the driving feeding wheel and the driven feeding wheel come into contact with each other, there will be a minimum gap between the two grooves on the outer sides of the driving feeding wheel and the driven feeding wheel. When conveying raw materials smaller than this gap, the driving feeding wheel and the driven feeding wheel cannot extrude and convey small-diameter steel wires or other raw materials, and it is necessary to replace the driving feeding wheel and the driven feeding wheel. On the one hand, the disassembly and assembly of the driving feeding wheel and the driven feeding wheel are inconvenient. On the other hand, it will also increase the downtime of the equipment and reduce production efficiency. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] As Figures 1-5As shown in the figure, a cold heading machine for screw processing provided by the utility model includes a base 1 and a raw material rack 2. A frame 3 is fixedly installed on the base 1. A crank pressure mechanism 4 is movably installed on one side inside the frame 3. A cold heading die 5 is also fixedly installed inside the frame 3 on one side of the crank pressure mechanism 4. A conveying mechanism 6 is arranged on the base 1 on one side of the frame 3. The conveying mechanism 6 includes a mounting frame 7 and a plurality of driving rollers 8. The mounting frame 7 is fixedly installed on the base 1. The driving rollers 8 are movably installed inside the mounting frame 7, and one side of the plurality of driving rollers 8 is connected to each other through gears in a meshing manner. One side of one of the driving rollers 8 is also fixedly connected to the output end of the motor of the mounting frame 7. A conveying wheel 9 is fixedly installed on the other side of the driving roller 8. The conveying wheel 9 includes two wheel bodies 10. A plurality of compensation blocks 12 are movably installed between the two wheel bodies 10. A punch 11 is also movably installed on the frame 3 on one side of the mounting frame 7.

[0022] As Figures 3-4 shown, fixed rings 13 are fixedly installed on the opposite sides of the two wheel bodies 10. A sleeve ring 14 is fixedly installed inside one of the fixed rings 13. An adjusting ring 21 is movably installed inside the other fixed ring 13. And the two wheel bodies 10 are fixedly connected by screws. A plurality of fixing blocks 15 are also respectively fixedly installed on the opposite sides of the two wheel bodies 10;

[0023] As Figures 2-5 shown, a sealing plate 16 is fixedly installed at the bottom of the compensation block 12. A screw groove 17 is opened at the bottom of the compensation block 12 inside the sealing plate 16. A top rod 18 is threadedly connected inside the screw groove 17. The bottom of the top rod 18 passes through the through hole inside the sealing plate 16 and extends to the position below the sealing plate 16. A gasket 19 is installed on the top rod 18 below the sealing plate 16 in a clamping and inserting manner. The compensation block 12 is inserted and installed in the through grooves on the opposite sides of the two wheel bodies 10. The top rod 18 below the gasket 19 then sequentially passes through the corresponding fixing blocks 15 and the through holes inside the fixed rings 13 and extends into the fixed rings 13. A compression spring 20 is sleeved on the top rod 18 between the gasket 19 and the sealing plate 16. By arranging a plurality of synchronously adjustable compensation blocks 12 between the two wheel bodies 10, after the distance between the two conveying wheels 9 is adjusted, it can be further adjusted according to the diameter of the steel wire. A conical seat 22 is fixedly installed on one side of the adjusting ring 21. A plurality of dial grooves 23 are opened on the side of the adjusting ring 21 away from the conical seat 22. And the adjusting ring 21 is threadedly connected inside one of the fixed rings 13. By rotating the adjusting ring 21 inside the corresponding fixed ring 13, the conical seat 22 can be made to synchronously extrude and move through the screw groove 17, and then cooperate with the compression spring 20 to realize the synchronous displacement adjustment of the plurality of compensation blocks 12 between the two wheel bodies 10.

[0024] It should be noted that the present utility model is a cold heading machine for screw processing. Before conveying steel wires or other processing raw materials with a relatively small diameter, tools such as a circlip pliers can be inserted into two of the dial grooves 23 on one side of the adjusting ring 21, thereby driving the adjusting ring 21 to rotate within one of the fixed rings 13. Then, the adjusting ring 21 drives the conical seat 22 to displace left and right within the fixed ring 13, and further utilizes the slope on the outer side of the conical seat 22 to achieve the displacement of the ejector rod 18. Thus, the ejector rod 18 drives the compensating block 12 to displace between the two wheel bodies 10 by virtue of the acting force of the compression spring 20 and the change in the slope of the conical seat 22. Then, by means of the synchronous displacement of multiple compensating blocks 12, the depth within the outer grooves of the two wheel bodies 10 can be adjusted, so as to ensure that the two conveying wheels 9 can squeeze and convey steel wires or other processing raw materials with a relatively small diameter. After the steel wires or other processing raw materials are conveyed into the machine frame 3 through the multiple conveying wheels 9, in cooperation with the crank pressure mechanism 4, the cold heading die 5, and the conveying mechanism 6, the cutting and cold heading treatment of the steel wires or other processing raw materials can be realized.
