[0002] A screw heading machine is an efficient and automated special machine in forging machinery. The screw heading machine is used in the fastener industry to produce various self-tapping screws, rivets, hinge pins and special parts. Due to the advantages of the cold forging equipment itself and the superiority of the cold forging technology, the high-speed screw cold heading machine is also widely used in various fields of the national economy.

The primary transmission mechanism includes a transmission platform and transmission rollers. The transmission platform is provided with two rows of first transmission rollers and second transmission rollers arranged front and back along the wire transmission direction. The first transmission rollers and the second transmission rollers are arranged in a staggered manner. An N-shaped groove is vertically arranged on the upper surface of one end of the transmission platform. The guiding mechanism includes a guiding plate. The other end of the transmission platform is vertically connected to the guiding plate through a connecting rod. A transmission hole is arranged on the guiding plate. The flattening mechanism includes an operation box, an upper pressing roller and a lower pressing roller. The beneficial effect of the utility model is that the wire passes through the primary transmission mechanism, the guiding mechanism and the flattening mechanism in sequence, and then enters the feeding port of the heading machine, so as to achieve the purpose of guiding the wire transmission, prevent the wire from bending, and be more convenient.

[0004] During the production of screws, it is necessary to wind the wire on a wire reel, and then directly introduce the wire head into the feeding device on the heading machine, so that the feeding device drives the wire to move, and the heading machine performs heading treatment on the wire. However, the feeding device on the heading machine cannot be adjusted and cannot meet the purpose of feeding wires with different diameters. Therefore, it is urgent to design a feeding device for a screw heading machine to solve the above problems. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a feeding device for a screw heading machine to solve the above deficiencies in the prior art.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A feeding device for a screw heading machine, comprising a box body assembly. On one outer wall of the box body assembly, two guiding assemblies are installed through bolts. The box body assembly includes a box body. On one side inner wall of the box body, a driving motor 1 is installed through bolts. On both sides of the inner wall of the box body, sliding grooves are opened, and a sliding frame is slidably connected inside the two sliding grooves. On one outer wall of the sliding frame, a driving motor 2 is installed through bolts. And the output ends of the driving motor 2 and the driving motor 1 are both installed with mounting shafts through bolts. Transmission wheels are arranged outside the mounting shafts. Inside the box body, a lead screw is installed through a bearing, and the lead screw is in threaded connection with the sliding frame. The top end of the lead screw is installed with a rotating head through a flat key.

[0008] Further, grooves are opened on both outer walls of the mounting shaft, and key blocks are slidably inserted inside the grooves. Between the two key blocks, two springs are installed through bolts.

[0009] Further, an extrusion block is slidably connected inside the mounting shaft, and the extrusion block is in contact with the two key blocks.

[0010] Further, an adjusting bolt is installed at one end of the mounting shaft through a bearing, and the adjusting bolt is in threaded connection with the extrusion block.

[0011] Further, key grooves are opened on both sides of the inner wall of the transmission wheel, and one end of the key block is inserted inside the key groove.

[0012] Further, ear plates are integrally formed on both outer walls of the box body, and through holes are opened on both sides of the top of the ear plates.

[0013] Further, the guiding assembly includes a box shell. On one outer wall of the box shell, an adjusting screw is threadedly connected, and one end of the adjusting screw is installed with an extrusion plate located inside the box shell through a bearing.

[0014] In the above technical solution, for a feeding device of a screw heading machine provided by the present utility model, the beneficial effects are as follows:

[0015] (1) By setting the rotating head, the lead screw and the sliding frame, when introducing different wire materials into the device, the rotating head can be rotated, so that the lead screw drives the sliding frame to slide inside the sliding groove, changing the distance between the two transmission wheels, enabling the two transmission wheels to clamp wire materials of different diameters, to meet the feeding requirements of the device for wire materials of different diameters.

[0016] (2) By setting the guiding assembly, when the wire material is driven by the transmission wheel to move, the adjusting screw can be rotated, so that the extrusion plate extrudes the wire material inside the box shell, thereby limiting the wire material and avoiding the problem of deviation when the transmission wheel drives the wire material to move.

[0017] (3) By setting the adjusting bolt, extrusion block, spring and key block, when the transmission wheel needs to be removed, the adjusting bolt can be turned with a wrench to make the extrusion block move away from the key block. Then, under the action of the spring, the two key blocks will retract into the groove, so that the restriction between the transmission wheel and the installation shaft is released, so as to facilitate the rapid replacement of the new transmission wheel.
