Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of electromagnetic forming, specifically to a simulation drive's reconfigurable modular plate pipe forming electromagnetic coil. BACKGROUND

[0002] As a kind of high energy rate forming process, electromagnetic forming technology shows significant advantages in the processing of metal plate and pipe in the field of automobile, aerospace and other fields, which realizes the high speed forming of material through pulse magnetic field force, and can effectively improve the forming performance of material.The core component of the technology is electromagnetic coil, and its structure design directly determines the magnetic field distribution, forming efficiency and workpiece quality.The traditional electromagnetic coil is usually designed and manufactured in an integrated manner for specific workpiece shape (such as flat plate, convex piece or pipe), and the coil structure is fixed and single function.

[0003] In the prior art, the disclosed coil is a whole structure that cannot be disassembled, and each coil can only realize the forming of a single type of feature.For example, flat plate forming coil cannot be used for pipe expansion, and pipe forming coil is difficult to be applied to plate shape correction with concave-convex features.This leads to the fact that in actual production, when facing the workpiece demand of different shapes, multiple special coils must be equipped, which not only increases the equipment purchase cost, but also brings the cumbersome problems of coil storage, management and replacement.In addition, once the whole coil is damaged, it often needs to be scrapped as a whole, which has high maintenance cost and lacks flexibility, and is difficult to adapt to the flexible manufacturing trend of small batch and multi-variety.

[0004] Therefore, the prior art lacks a general coil solution that can be flexibly reconfigured and applied to various forming scenarios. UTILITY MODEL CONTENTS

[0012] Further, the total height of the first fixed connecting part, the second fixed connecting part and the connecting block after connection is greater than the height of the coil component, and the coil structure formed is a convex coil or a spiral coil.

[0013] Further, the total height of the first fixed connecting part, the second fixed connecting part and the connecting block after connection is less than the height of the coil component, and the coil structure formed is a concave coil.

[0014] Further, the connecting piece is a screw, the first fixed connecting part and the second fixed connecting part are provided with corresponding threaded holes, the connecting block is provided with a corresponding through hole, and the first coil component and the second coil component are connected by screwing the screw into the threaded hole and the through hole.

[0030] In order to make the person skilled in the art better understand the technical scheme of the present application, the technical scheme in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by the person skilled in the art without creative labor should belong to the protection scope of the present application.

[0031] The utility model provides a kind of modular electromagnetic coil structure.The basic component unit of this structure is coil component 1, it is preferably C type structure, and the opening direction of the C type structure coil component 1 is perpendicular to the plane formed by the coil structure finally assembled.The first end and the end of each coil component are provided.There is detachable connection between the components, and the utility model is provided with connecting mechanism, and the connecting mechanism includes connecting block 2 and connecting piece 3.The connecting block 2 and the coil component 1 are made of high-conductivity metal material (such as copper or copper alloy), to ensure that the entire coil loop has good conductivity.

[0032] For the two adjacent coil components 1, the end of the first coil component 10 is provided with the first fixed connecting part 101 outwardly protruding, the first end of the second coil component 11 is provided with the second fixed connecting part 110, and the detachable connecting block 2 is arranged between the first fixed connecting part 101 and the second fixed connecting part 110.

[0033] Preferably, the first fixed connecting part 101 and the first coil component 10 are integrally formed, and the second fixed connecting part 110 and the second coil component 11 are also integrally formed, to ensure the mechanical strength and electrical reliability of the connection.The first fixed connecting part 101 and the second fixed connecting part 110 are provided with corresponding threaded holes, and the connecting block 2 is provided with corresponding through holes, and the axial direction is parallel to the height direction of the connecting block 2 (i.e. the axial direction of the coil).

[0034] The connecting piece 3 is a screw, and by screwing the screw into the threaded hole and the through hole, the first fixed connecting part 101, the connecting block 2 and the second fixed connecting part 110 are connected, so that the two coil components are connected end to end to form an electrically continuous and structurally continuous coil turn.

[0035] By replacing connecting blocks of different axial sizes (i.e. height), the connecting height formed after the first coil component 10 and the second coil component 11 are connected (i.e. the relative position difference of the two adjacent coil components in the axial direction) can be changed, so that coil structures with different profiles can be quickly reconstructed to meet different workpiece forming requirements.

[0036] Embodiment one: flat coil

[0037] Referring to Figure 2 , the embodiment aims to assemble a flat coil for forming flat workpieces.

[0038] Select multiple coil components, and equip each pair of adjacent coil components with a connecting block 2. After connecting through screws, the total connecting height (i.e. the first fixed connecting part 101 + the second fixed connecting part 110 + the connecting block 2) is equal to the height of the single coil component itself. As shown in Figure 2 , after all components are connected in sequence through such connecting blocks, the coil components are in a flush state in the axial direction, thereby forming a flat annular coil with no height difference between turns, i.e. a flat coil, which is suitable for forming flat metal materials.

[0039] Example Two: Convex Coil and Spiral Coil

[0040] Referring to Figure 3 and Figure 5 , the embodiment aims to show how to assemble a convex coil or a spiral coil by increasing the connecting height.

[0041] For the convex coil ( Figure 3 ): Select multiple coil components, and equip one or more pairs of adjacent coil components with connecting blocks 2, so that the connecting height (i.e. the first fixed connecting part 101 + the second fixed connecting part 110 + the connecting block 2) after connection at these positions is significantly greater than the height of the coil component itself. As shown in Figure 3 , this will cause the coil components to have an axial convexity at these positions. Through the combination of different connecting block heights, a convex coil for convex feature correction and multi-step forming can be constructed.

[0042] For the spiral coil ( Figure 5 ): Select multiple coil components, and equip each pair of adjacent coil components with a connecting block 2, and all connecting blocks 2 are of the same specification, so that the connecting height (i.e. the first fixed connecting part 101 + the second fixed connecting part 110 + the connecting block 2) after connection at each position is much greater than the height of the coil component itself. As shown in Figure 5 , when all coil components are connected in sequence, the entire coil will exhibit a spiral structure continuously extending in the axial direction, i.e. a spiral coil, which is suitable for tube expansion processing.

[0043] Example Three: Concave Coil

[0044] Referring to Figure 4 , the embodiment aims to assemble a concave coil for forming concave workpieces.

[0045] Select a plurality of coil parts, for one or more pairs of adjacent coil parts equipped with connecting block 2, so that these positions after the connection of the connecting height (i.e. the first fixed connection part 101 + the second fixed connection part 110 + connecting block 2) is less than the height of the coil parts itself. As shown in Figure 4 It will make the coil in the position to form an axial recess. By adding a plurality of connecting blocks, a concave coil can be constructed to match the profile of the concave workpiece, for the concave feature of the shaping and multi-step forming.

[0046] In summary, the utility model discloses a modular design and the combination of different connecting block height, realizes the multifunction of single coil device, effectively solves the problem of traditional coil function single, poor adaptability.In addition, by changing the inner diameter of the parts and increasing the number of coil parts, more complex plate / tube forming, such as multi-feature concave-convex plate (e.g. Figure 6 ) and the like can be realized, and has a wide application prospect.

[0047] The above is only the preferred embodiment of the utility model, it should be pointed out, for the ordinary skill in the art, without departing from the principle of the utility model, can make a number of improvements and refinements, these improvements and refinements also should be considered the protection scope of the utility model.
