Description

Technical Field

[0001] The utility model relates to a full-automatic compression spring machine capable of stably blanking materials, belonging to the field of spring processing equipment. Background Art

[0002] Compression springs (compression springs) are coil springs that withstand axial pressure. The cross-section of the material used is mostly circular, and there are also rectangular and multi-strand steel windings. The springs are generally of equal pitch. The shapes of compression springs include: cylindrical, conical, convex and concave, as well as a small number of non-circular shapes. There is a certain gap between the coils of the compression spring. When subjected to external loads, the spring contracts and deforms to store deformation energy.

[0003] The fully automatic compression spring machine can use programs to control the feeding, pressing and blanking, realizing the automation of compression spring production. Due to the large number of diameter rods in the compression spring structure and the arrangement around the core shaft, the compression spring pops out instantly at the moment of processing and forming, and cannot be blanked smoothly and centrally.

[0004] The existing public application number is 201811347054.X, and the patent application name is a fully automatic compression spring machine with smooth blanking. During the spring extrusion molding process, a distance measuring mechanism is provided in the direction of outward movement. The distance measuring mechanism includes a V-shaped groove. The V-shaped groove and the receiving groove are on the same horizontal plane and are located in the direction of outward extension of the spring. A guide rail is provided on the inner surface of the V-shaped groove. A circular sensing head that can slide back and forth along the guide rail is provided on the guide rail. The circular sensing head is fixed on the V-shaped groove. A cutting mechanism is provided on the side of the receiving groove. The circular sensing head is simultaneously connected to the motor that drives the active discharge tray and the cutting mechanism. The position of the circular induction head in the V-shaped groove can be controlled. According to this feature, the length of the final product can be controlled. During the extrusion molding process of the spring, it touches the circular induction head outward. At this time, the induction head controls the motor to stop feeding and controls the cutting mechanism to cut off the spring. A blanking basket is provided below the accommodating groove and the V-shaped groove. The blanking basket is a trough-shaped structure with an upper opening. Several blanking pieces are staggered on the left and right inner parts of the blanking basket. The angle between the blanking piece and the inner wall of the blanking basket connected to it is 45°-60°. Because some precision springs are soft in texture, they are easily damaged when falling.

[0005] However, there is still a problem with the above design. When the compression spring is formed, it pops out instantly and may not fall directly into the blanking basket. It may also be stuck between adjacent radial rods.

[0006] Therefore, the utility model provides a full-automatic compression spring machine which can blank materials stably and centrally. Utility Model Content

[0007] In view of this, the purpose of the present invention is to provide a fully automatic compression spring machine that can blank materials smoothly and centrally.

[0030] Reference Figure 1-Figure 5 As shown, this embodiment provides a specific implementation method for a fully automatic compression spring machine capable of stably blanking, comprising an air control unit 20 installed below a core shaft 10; a blanking hopper 30, located at the front end of the air control unit 20, for receiving the finished compression springs;

[0031] It also includes several groups of wire feeding wheels 40, an equipment body 50, and radial rods 60. A wire feeding wheel 40 for conveying wire is installed on one side of the equipment body 50. The core shaft 10 is installed on the equipment body 50. There are several radial rods 60, which are arranged on the equipment body 50 around the core shaft 10.

[0032] The utility model conveys the wire to the position of the core shaft 10 through the wire feeding wheel 40, processes the wire into a compression spring through the radial rod 60, and after processing, blows it away from the position of the radial rod 60 through the air control unit 20. The compression spring moves forward and falls directly into the drop hopper 30, achieving the purpose of smooth and concentrated drop.

[0033] Among them, the air control unit 20 includes a fan 201, an air supply duct 202, a valve 203 and an air outlet 204. The air outlet 204 is arranged below the core shaft 10, and the air outlet 204 is connected to the fan 201 through the air supply duct 202. A valve 203 is provided on the air supply duct 202. The valve 203 controls the air supply volume in the air supply duct 202, so that the air volume of the air outlet 204 remains unchanged, the air outlet is stable, and it directly acts on the compression spring, so that the compression spring is easily blown off.

[0034] Among them, the blanking hopper 30 includes a main body 301, a bracket 302, a buffer plate 303, and a conveyor 304. The main body 301 is installed at one end of the conveyor 304 through the bracket 302. Several buffer plates 303 are arranged in sequence from top to bottom inside the main body 301. The buffer plates 303 are used as buffers for the falling of the compression spring. After blanking, it is transported out via the conveyor and directly proceeds to the next process; there is no need to approach the fully automatic compression spring machine at close range, and automatic production can be achieved to improve production efficiency.

[0035] Furthermore, the buffer plate 303 is assembled on the bayonet of the main body 301 at a preset angle A, wherein the preset angle A is 0°-90°; and the inclination angle of the buffer plate 303 located above the main body 301 is smaller than that of the buffer plate 303 below the main body 301, resulting in a slow blanking speed of the upper buffer plate 303 and a fast blanking speed of the lower one, thereby widening the blanking distance between the two adjacent compression springs to prevent the two from being cross-stacked together.

[0036] In one specific embodiment, the first surface 311 of the main body 301 is perpendicular to the end surface of the conveyor 304, and the angle between the second surface 312 of the main body 301 and the horizontal plane is 0°-90°. The inclined setting makes it easier to concentrate the dropping of materials.

[0037] Furthermore, the top opening of the main body 301 is rectangular, and the width of the main body 301 is two-thirds of the width of the equipment main body 50 , so that the compression spring blown off by the controlled wind unit 20 can also fall into the drop hopper 30 more easily.

[0038] In one specific embodiment, the buffer plate 303 includes a plate body 331 and a plurality of slots 332 opened on the end surface of the plate body 331 , and the slots 332 are distributed at equal distances.

[0039] Furthermore, a plurality of bayonet holes are formed on the first surface 311 of the main body 301 in the vertical direction, and the bayonet holes are detachably connected to the bayonet holes by the bayonet holes 332 on the buffer plate 303 .

[0040] Adjust the engagement between the slot 332 of the buffer plate 303 and the bayonet, and further adjust the length of the buffer plate 303 inside the main body 301. The longer the length, the longer the time required for blanking, and the longer the distance between two adjacent compression springs after they fall on the conveyor, giving the next process reaction time.

[0041] In one specific embodiment, the cross-section of the slot 332 is triangular, and when it is engaged with the bayonet, the structure is stable.

[0042] In one specific embodiment, the cross-section of the slot 332 is rectangular. When it is locked in the bayonet, the structure is stable and can be adjusted and moved forward and backward.

[0043] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
