Description

Technical Field

[0001] This utility model relates to the field of bushing retraction technology, specifically to a diameter reduction ejection device. Background Technology

[0002] A necking machine, also known as a non-cutting machining equipment, offers advantages such as increased production efficiency, simple process, ease of operation, raw material savings, and stable quality. It utilizes hydraulic technology to feed the portion of round steel or threaded steel that needs to be necked into a specialized mold for cold shrinking and compression forming. The density of the necked portion of the steel can be significantly increased, thereby improving the material's compressive strength.

[0003] After the current reducing machine completes the reducing process, the product is still inside the machine. Operators need to reach into the machine to remove the product and proceed to the next process. This cumbersome process not only increases the labor intensity of operators but also poses safety hazards and fails to lay the foundation for subsequent automatic reducing. Utility Model Content

[0004] The purpose of this invention is to provide a reasonably designed diameter-reducing ejection device that addresses the defects and shortcomings of existing technologies, thereby solving the aforementioned deficiencies.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: it includes a cylinder, a first mechanism component, a second mechanism component, a third mechanism component, and a fourth mechanism component. The first mechanism component is disposed on the cylinder, the second mechanism component is disposed above the cylinder, the third mechanism component is sleeved on the second mechanism component, and the fourth mechanism component is sleeved on the second mechanism component and fixed with a set screw.

[0006] Preferably, the second, third, and fourth side walls of the mechanism component are respectively provided with set screw holes, and the three set screw holes are on a horizontal straight line.

[0007] Preferably, the cylinder is bolted to the reducing machine.

[0008] Preferably, the mechanism component is bolted to the cylinder head flange.

[0009] Preferably, the second mechanism component is connected to the screw on the cylinder.

[0010] Preferably, the mechanism component has steps on its fourth side.

[0011] The beneficial effects of this utility model after adopting the above structure are:

[0012] 1. This utility model utilizes the extension and retraction of a cylinder to eject the finished product from the reducing machine. This structure eliminates the need for operators to reach into the reducing machine to remove the product, reducing the labor intensity of operators, eliminating safety hazards, and laying the foundation for subsequent automatic reducing.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1-3 As shown, the reduced diameter ejection device proposed in this utility model includes a cylinder 1, a first mechanism 2, a second mechanism 3, a third mechanism 4, and a fourth mechanism 5. The first mechanism 2 is disposed on the head of the cylinder 1, the second mechanism 3 is disposed above the cylinder 1, the third mechanism 4 is sleeved on the second mechanism 3, and the fourth mechanism 5 is sleeved on the second mechanism 3 and fixed with a set screw.

[0020] The side walls of mechanism component 2 (3), mechanism component 3 (4), and mechanism component 4 (5) are respectively provided with set screw holes 6, and the three set screw holes 6 are on a horizontal straight line;

[0021] Cylinder 1 is bolted to the reducing machine;

[0022] The mechanism component 2 is bolted to the head flange of cylinder 1;

[0023] Mechanism component 2 3 is connected to the screw on cylinder 1;

[0024] The fourth component of the mechanism is equipped with a step 7.

[0025] As an optimized solution of this utility model, the third mechanism component 4 is set on the second mechanism component 3 for easy replacement; the second mechanism component 3, the third mechanism component 4 and the fourth mechanism component 5 are provided with set screw holes 6, and the fourth mechanism component 5 can be fixed on the second mechanism component 3 with set screws; the step 7 on the fourth mechanism component 5 can be used to place the product, so that the rod passes through the middle hole of the product.

[0026] The usage process of this utility model:

[0027] First, the automatic ejection function of this device can only be realized after it is connected to the whole equipment. A single device cannot achieve automatic operation. After being connected to the whole equipment, when the reducing machine completes the reducing process, it will send a command to the PLC. The PLC can control the extension and retraction of the cylinder. When the cylinder extends, it pushes the product from inside the reducing machine to the outside.

[0028] It should be understood that the above-described specific embodiments of this utility model are merely illustrative or explanatory of the principles of this utility model and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of this utility model should be included within the protection scope of this utility model.
