Description

Technical Field

[0001] This utility model relates to the field of cold heading machine feeding technology, and in particular to an automatic cold heading machine feeding control mechanism for steel balls. Background Technology

[0002] A cold heading machine is a specialized piece of equipment used for the mass production of fasteners such as nuts, bolts, washers, and screws. It primarily relies on cold heading technology for processing. In this process, the metal material does not undergo heat treatment; instead, it is shaped into the desired form at room temperature through mechanical pressure. Cold heading not only enables efficient large-scale production but also ensures high precision and consistency of the products. Its principle typically involves placing the metal material in a mold and applying high pressure to achieve deformation processes such as pressing, stretching, and extrusion. Cold heading machines are widely used in the fastener and precision parts industries. Due to their high production capacity, low energy consumption, and high material utilization rate, they have become an indispensable piece of equipment in modern machinery manufacturing. Furthermore, cold heading machines can be customized and adjusted according to the requirements of different products, further enhancing their application value in various industrial fields.

[0003] In existing technologies, cold heading machines often experience blockages in the feeding path due to excessive material accumulation during the feeding operation. Excessive material buildup can prevent material from smoothly entering the machine's feeding channel or cause jams during transport, thus affecting the normal production process. This not only leads to decreased production efficiency but may also cause equipment malfunctions, increasing maintenance and downtime, thereby impacting the overall stability and output of production.

[0004] Therefore, it is necessary to provide a new feeding control mechanism for an automatic cold heading machine for steel balls to solve the above-mentioned technical problems. Utility Model Content

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0023] Please see Figures 1 to 4 This utility model provides a feeding control mechanism for an automatic cold heading machine for steel balls, which includes:

[0024] The shell 1 has two columns 2 fixed symmetrically on both sides of the bottom end of the shell 1. The two columns 2 are fixed with a support frame 3 at the end away from the shell 1. The two support frames 3 are provided with a vertically rotating mold body 4 on the opposite side. The stamping machine body 5 is installed in the center of the bottom end of the shell 1. An electric push rod 6 is provided on one side surface of the shell 1.

[0025] It should be noted that the vertical center axis of the press body 5 and the vertical center axis of the mold body 4 are on the same vertical line, which effectively ensures the accuracy and stability of the press body 5 in working with the mold body 4.

[0026] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 The output end of the electric push rod 6 is fixed with a fixing block 7. The bottom end of the housing 1 is laterally slidable with a diverter plate 8. The side of the fixing block 7 close to the housing 1 is fixed to the diverter plate 8 through a connecting rod. The bottom end of the housing 1 is provided with a sliding groove 9 for the diverter plate 8 to slide. The top end of the housing 1 is provided with a feeding hopper 10. The feeding hopper 10 and the sliding groove 9 are connected through a connecting pipe 12.

[0027] It should be noted that the flow divider 8 is driven by the electric push rod 6 to reciprocate inside the slide groove 9. The sliding distance of the flow divider 8 can only allow one steel ball to enter the guide pipe 13.

[0028] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 The shape of the flow divider 8 is an isosceles trapezoid, and the inclination angle of the two ends of the flow divider 8 along the sliding direction is 10° to 15°.

[0029] It should be noted that the two ends of the diverter plate 8 can be tangent to the surface of the steel ball to avoid the diverter plate 8 squeezing the steel ball.

[0030] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 The inner side of the feed hopper 10 is provided with a W-shaped groove 11, and the bottom position of the W-shaped groove 11 corresponds to the position of the connecting pipe 12.

[0031] It should be noted that the W-shaped groove 11 effectively ensures that the steel ball can stably enter the interior of the connecting pipe 12.

[0032] In the embodiments of this utility model, please refer to Figure 3 The interior of the column 2 is provided with a guide pipe 13. The end of the guide pipe 13 near the shell 1 is connected to the slide groove 9. The two columns 2 are provided with a discharge groove 14 connected to the guide pipe 13 on their inner lower sides. The bottom end of the discharge groove 14 corresponds to the top end of the mold body 4.

[0033] It should be noted that the guide tube 13 is S-shaped, and the inner diameter of the guide tube 13 is the same as the diameter of the steel ball.

[0034] In the embodiments of this utility model, please refer to Figure 3 The mold body 4 is controlled to rotate by a first motor 16 provided in a support frame 3. A guide groove 15 is provided at the top of the mold body 4, and baffles 17 are symmetrically fixed on both sides of the top of the mold body 4.

[0035] It should be noted that the two ends of the mold body 4 are in contact with the inner sides of the two support frames 3.

[0036] In the embodiments of this utility model, please refer to Figure 3 The inclination angle of the baffle 17 is 70° to 80°, and the inclination angle of the guide chute 15 is 30° to 45°.

[0037] It should be noted that the baffle 17 can effectively prevent the steel ball from detaching from the mold body 4, and at the same time, it is beneficial to guide the processed workpiece.

[0038] The working principle of the automatic cold heading machine feeding control mechanism for steel balls provided by this utility model is as follows: The user puts the steel ball into the feeding hopper 10 inside the housing 1, and guides the steel ball through the W-shaped groove 11, so that the steel ball in the W-shaped groove 11 slides naturally into the connecting pipe 12 due to gravity, and rolls close to the slide 9 inside the connecting pipe 12. Then, it is connected to the diverting plate 8 through the fixing block 7 on the electric push rod 6. The electric push rod 6 drives the diverting plate 8 to reciprocate inside the slide 9, so that the steel ball intermittently enters the guide pipe 13 through the slide 9. Through the rolling of the steel ball inside the guide pipe 13, the steel ball is finally guided into the mold body 4 through the discharge groove 14, and the baffle 17 prevents the steel ball from flying out. When the steel ball is naturally placed in the center of the mold body 4 through the guide groove 15, the steel ball is processed by the stamping machine body 5. The processed workpiece is easily collected by the user through the rotation of the mold body 4.

[0039] The circuits and controls involved in this utility model are all existing technologies and will not be described in detail here.

[0040] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
