Description

Technical Field

[0001] This utility model relates to the technical field of elastic component forming equipment, and in particular to a device for processing multi-curvature elastic components. Background Technology

[0002] Multi-curvature elastic elements refer to complex curved surface elastic elements with multiple different radii of curvature. Multi-curvature elastic elements are mostly made of highly elastic materials (such as spring steel and composite materials). By superimposing multiple curvatures, stress distribution is optimized and the risk of local fatigue is reduced. They are widely used in aerospace, automotive, industrial equipment and precision instruments.

[0003] To address this, Chinese Patent No. CN113967681B proposes a device for processing multi-curvature elastic components, comprising an upper template mechanism and a lower template mechanism. The lower surface of the upper template mechanism has multiple downwardly extending inclined wedges. The upper surface of the lower template mechanism has a forming module and a slider unit. When the upper and lower template mechanisms move relative to each other, the inclined wedges push the slider unit to form the multi-curvature elastic component. The slider unit includes at least one first slider unit with a first top block. The first top block can move towards the forming module along a direction at an angle to the upper surface of the lower template mechanism under the action of the corresponding inclined wedges.

[0004] Although the above-mentioned device can form multiple curved parts at once, avoiding the situation where the rebound of the sheet metal is different under different bending processes and thus the forming quality is poor, the device cannot perform continuous processing. After the device finishes processing the multi-curvature elastic parts, the multi-curvature elastic parts need to be removed, and then new multi-curvature elastic parts raw materials need to be placed before processing is carried out again. The entire removal and placement process takes a certain amount of time, thus affecting the processing efficiency of multi-curvature elastic parts. Utility Model Content

[0005] The purpose of this invention is to provide a device for processing multi-curvature elastic components, so as to solve the problems mentioned in the background art.

[0023] Compared with the prior art, the beneficial effects of this utility model are:

[0024] By using a first lower mold, a second lower mold, and an electric push rod, after the multi-curvature raw material on the second lower mold is processed, the electric push rod moves the first lower mold to the processing table via a connecting block.

This cyclical operation, through this alternating movement processing method, enables the connection processing of multi-curvature elastic components, thereby improving the processing efficiency of multi-curvature elastic components.

[0036] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "transverse," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product of this utility model is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are only used to facilitate the description of this utility model and to simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0037] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0038] Given that the existing technology does not allow for continuous processing, after the device processes the multi-curvature elastic component, it is necessary to remove the multi-curvature elastic component, place a new multi-curvature elastic component raw material, and then process it again. The entire process of taking and placing the component takes a certain amount of time, which affects the processing efficiency of the multi-curvature elastic component.

[0039] like Figure 1-4 As shown, this utility model embodiment provides a device for processing multi-curvature elastic components, comprising:

[0040] A processing table 1 is provided with a fixed base 11 on one side of the top front of the processing table 1;

[0041] The processing table 1 is used for processing elastic components with multiple curvatures, and the fixed base 11 is used for connection and support.

[0042] Feeding component 3, which includes:

[0043] Electric push rod 31, the fixed end of electric push rod 31 is fixedly set on one side of fixed base 11;

[0044] Connecting block 32, one side of which is fixedly mounted on the telescopic end of electric push rod 31;

[0045] The first lower mold 33 has one end fixedly mounted on one side of the connecting block 32;

[0046] Connecting plate 34, one end of which is fixedly mounted on the other end of the first lower mold 33;

[0047] The second lower mold 35 has one end fixedly mounted on the other end of the connecting plate 34;

[0048] The electric push rod 31 is used to provide the driving force required for the movement of the first lower die 33 and the second lower die 35. The connecting plate 34 is used to connect the first lower die 33 and the second lower die 35 so that they move synchronously. There are two connecting plates 34. Another connecting plate 34 is connected to the other side of the first lower die 33 and the second lower die 35. The top connection structure of the first lower die 33 and the second lower die 35 is the same, and both are provided with stamping parts for processing and forming multi-curvature elastic parts.

[0049] Furthermore, the feeding assembly 3 also includes:

[0050] Four support bases 36 are fixedly installed on one side of the processing table 1, and two guide rods 37 are provided on the inner side wall of the four support bases 36.

[0051] The support base 36 is L-shaped.

[0052] Furthermore, a rod seat 12 is fixedly provided on the outer wall of the electric push rod 31, and one side of the rod seat 12 is fixedly provided on the other side of the top front of the processing table 1.

[0053] The rod holder 12 is used to provide auxiliary connection and support for the electric push rod 31, thereby improving the overall stability of the electric push rod 31.

[0054] Furthermore, a fixed frame 2 is fixedly provided on one side of the top of the processing table 1, a hydraulic cylinder 4 is fixedly provided on the top of the fixed frame 2, and an upper mold 5 is fixedly provided on the telescopic end of the hydraulic cylinder 4.

[0055] The hydraulic cylinder 4 is used to provide the driving force required for the upper mold 5 to move up and down. The telescopic end of the hydraulic cylinder 4 passes through the top of the fixed frame 2 and slides in cooperation with the fixed frame 2.

[0056] Furthermore, the outer walls of the two guide rods 37 respectively penetrate the first lower mold 33 and the second lower mold 35, and slide in cooperation with the first lower mold 33 and the second lower mold 35;

[0057] The guide rod 37 is used to guide and limit the first lower mold 33 and the second lower mold 35, so that they slide along the outer wall of the guide rod 37.

[0058] The working principle is as follows: Multi-curvature elastic material is placed at the top of both the first lower mold 33 and the second lower mold 35. The hydraulic cylinder 4 is opened, causing the upper mold 5 to move downwards until it is positioned with the lower second mold 35. The mold then processes the multi-curvature elastic material. After processing, the hydraulic cylinder 4 is opened again, causing the upper mold 5 to move upwards and reset. Then, the electric push rod 31 is opened, causing it to retract and reset, moving the connecting block 32 to the right. This movement of the connecting block 32 moves the first lower mold 33 below the upper mold 5. The first lower mold 33 then moves the second lower mold 35 outwards from below the upper mold 5 via the connecting plate 34. The same process is repeated for the multi-curvature elastic material at the top of the first lower mold 33. During processing intervals, the multi-curvature elastic material at the top of the second lower mold 35 is removed and new material is placed. This cycle is repeated, allowing for continuous processing of multi-curvature elastic materials, thus improving processing efficiency.

[0059] Specifically, such as Figure 1-4 As shown, it also includes:

[0060] The four sides of the top of the first lower mold 33 are all fixedly provided with guide sleeves 331, the four sides of the bottom of the upper mold 5 are all fixedly provided with guide posts 51, the bottom ends of both sides of the guide posts 51 are all fixedly provided with fixed frames 52, and the inner walls of the two fixed frames 52 are rotatably provided with rollers 53.

[0061] The guide sleeve 331, in conjunction with the guide post 51, is used to position the upper and lower molds. The roller 53 is used to convert the sliding friction between the guide post 51 and the guide sleeve 331 into rolling friction. When the electric push rod 31 is in its initial position and at its maximum stroke, the guide sleeve 331 on the first lower mold 33 and the second lower mold 35 is located directly below the guide post 51.

[0062] Both sides of the guide sleeve 331 are provided with through grooves 332, and both sides of the guide post 51 are fixed with auxiliary blocks 54;

[0063] The inner diameter of the through groove 332 is adapted to the outer diameter of the auxiliary block 54.

[0064] Furthermore, the outer wall of roller 53 and the inner wall of fixed sleeve 331 are located on the same vertical plane on opposite sides.

[0065] Working principle: During the processing of multi-curvature elastic components, when the hydraulic cylinder 4 works, it drives the upper mold 5 to move downward. The downward movement of the upper mold 5 drives the positioning pin 51 to move downward until the rollers 53 on both sides of the positioning pin 51 come into contact with the inner wall of the positioning sleeve 331. As the positioning pin 51 moves downward, the rollers 53 slide downward along the inner wall of the fixed sleeve 331. In this way, the upper and lower molds can be moved and positioned, and the sliding friction between the positioning pin 51 and the positioning sleeve 331 is changed to rolling friction, thereby reducing the contact resistance between the two and improving the positioning effect. When the rollers 53 slide downward along the inner wall of the fixed sleeve 331, the auxiliary block 54 moves downward along the through groove 332 on one side of the positioning sleeve 331. This can assist in the positioning of the positioning pin 51 and the positioning sleeve 331, thereby further improving the positioning effect.

[0066] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
