Abstract

The present invention discloses a gap support mechanism for explosive welding of composite plates. The gap support mechanism includes: a central support member; and a plurality of edge support members located around the central support member. The edge support members are connected to the central support member via connecting rods, so that the central support member and all the edge support members form an integral structure, which is supported between the base plate and the composite plate used for explosive welding. The gap support mechanism completely subverts the existing support method of independent support plates.

The gap support mechanism can be applied to different composite plate explosive welding processes and can achieve mass production.

Description

Technical Field

[0001] The invention relates to the technical field of explosive composite plate processing equipment, and in particular to a gap supporting mechanism for explosive welding of composite plates. Background Art

[0002] The production method of explosively welded composite plates is to place the prepared composite plates on a base plate, with the composite plates and the base plate supported by a gap support plate, and then lay a layer of explosives on the composite plates. The instantaneous ultra-high pressure and ultra-high speed impact energy generated by the explosion of the explosives are used to achieve solid-state metallurgical bonding between the metal layers.

[0003] In the explosive welding process, the smooth discharge of gas in the gap between the base plate and the composite plate is a prerequisite for ensuring the quality of the joint. At present, the support mechanisms used in the gap between the base plate and the composite plate are mostly made of metal sheets folded into a fixed "V" or "W" shape. There is no connection between these metal sheets, which makes the support stability insufficient. In addition, the spacing between the supports is an important parameter, which not only determines the nature of the impact process, but also determines the strength of the boundary effect. The existing support mechanism uses separate support sheets, and the spacing needs to be controlled one by one, which makes the layout operation very troublesome and the accuracy of the spacing is also reduced. Furthermore, the metal sheet adopts a fixed shape and its support height cannot be adjusted. As a result, different support sheets need to be processed in advance for different explosive welding processes. Mass production cannot be achieved, which is not conducive to improving production efficiency. Summary of the Invention

[0004] The purpose of the present invention is to provide a gap support mechanism for explosive welding of composite plates, which solves the problems of insufficient support stability, the need to control the spacing one by one, cumbersome operation, inability to adjust the support height and inability to be mass-produced in existing support mechanisms for explosive welding of composite plates.

[0005] The present invention achieves the above-mentioned purpose through the following technical solutions:

[0006] A gap support mechanism for explosive welding of composite plates, the gap support mechanism comprising:

[0007] a center support; and

[0008] A plurality of edge supports are located around the central support member and are connected to the central support member through connecting rods, so that the central support member and all the edge supports form an integral structure, which is supported between the base plate and the composite plate for explosion welding.

[0009] A further improvement lies in that the central support member includes a central connection seat, a central top rod provided at the top end of the central connection seat, a rotating seat rotatably provided at the bottom end of the central connection seat, a central threaded rod provided at the bottom end of the rotating seat, and a central threaded sleeve threadedly connected to the central threaded rod; the edge support member includes an edge connection seat, an edge top rod provided at the top end of the edge connection seat, an edge threaded rod provided at the bottom end of the edge connection seat, and an edge threaded sleeve threadedly connected to the edge threaded rod;

[0011] A further improvement lies in that a dial protruding from the central connection seat and the central threaded sleeve is formed on the outer ring of the rotating seat.

[0012] A further improvement lies in that a counterweight is provided at the bottom end of the edge threaded sleeve, and the lead angle of the edge threaded rod and the edge threaded sleeve is greater than 45°.

[0013] A further improvement lies in that the central threaded rod and the central threaded sleeve are in fine thread fit.

[0014] A further improvement lies in that the central support member and all the edge support members form a cross-shaped integral structure, and the distance between the central support member and the edge support members is equal.

[0015] A further improvement lies in that the central support member and all the edge support members form a "field" - shaped integral structure, and the adjacent edge support members are also connected by connecting rods, and the distances between the horizontally and vertically adjacent edge support members, as well as between the central support member and the edge support members, are equal.

[0016] A further improvement lies in that the connecting rods are all horizontally arranged and are of a freely telescopic structure.

[0017] A further improvement lies in that the gap support mechanism further includes an adjusting screw tube, the adjusting screw tube horizontally penetrates through the central connection seat and is rotatably matched with the central connection seat, the two ends of the adjusting screw tube extend outwards, and two moving rods are respectively threadedly connected to the two ends through opposite threads, the two moving rods are aligned with two edge support members located at one diagonal position of the "field" - shaped integral structure, and are fixedly connected to the edge connection seats of the edge support members.

[0018] A further improvement lies in that anti - slip threads are provided on the outer wall of the tube section where the adjusting screw tube extends.

[0019] The beneficial effects of the present invention are as follows:

[0020] (1) This gap support mechanism completely overturns the existing support method of independent support pieces. All its support parts are an integral structure, which greatly improves the support stability and does not affect the smooth discharge of gas in the gap;

[0031] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0032] Example 1

[0033] Combine Figures 1 to 4 As shown, a gap support mechanism for explosive welding of composite plates, the gap support mechanism includes:

[0034] a central support 1; and

[0035] Several edge supports 2 are located around the central support 1. The edge supports 2 are connected to the central support 1 through connecting rods 3, so that the central support 1 and all edge supports 2 form an integral structure. Here, there are four edge supports 2. The central support 1 and all edge supports 2 form a cross-shaped integral structure, and the spacing between the central support 1 and the edge supports 2 is equal. Through the integral structure, it is supported between the base plate and the composite plate used for explosive welding, and its support stability is greatly improved, and it will not affect the smooth discharge of gas in the gap.

[0036] In the present invention, the center support member 1 includes a center connecting seat 11, a center top rod 12 provided at the top of the center connecting seat 11, a rotating seat 13 rotatably provided at the bottom end of the center connecting seat 11, a center threaded rod 14 provided at the bottom end of the rotating seat 13, and a center threaded sleeve 15 threadedly connected to the center threaded rod 14; the edge support member 2 includes an edge connecting seat 21, an edge top rod 22 provided at the top end of the edge connecting seat 21, an edge threaded rod 23 provided at the bottom end of the edge connecting seat 21, and an edge threaded sleeve 24 threadedly connected to the edge threaded rod 23; the end of the connecting rod 3 is fixedly connected to the center connecting seat 11 or the edge connecting seat 21.

[0037] like Figure 7 As shown, for most explosive welding processes of composite panels, only one gap support mechanism is required. The center support member 1 is located at the center of the base plate 100 and the composite panel 200, while the edge support member 2 is located at the edge (or near the edge) of the base plate 100 and the composite panel 200. The center support member 1 is supported on the surface of the base plate 100 by the bottom of the center threaded sleeve 15 and on the bottom surface of the composite panel 200 by the center push rod 12. The edge support member 2 is supported on the surface of the base plate 100 by the bottom of the edge threaded sleeve 24 and on the bottom surface of the composite panel 200 by the edge push rod 22. For the explosive welding process of large-area composite panels, a support method combining multiple gap support mechanisms can be used. Compared with the traditional support method of a single support piece, the simplicity of the layout process and the support stability are significantly improved.

[0038] When the support height needs to be adjusted, it is only necessary to place the gap support mechanism on the surface of the substrate 100 and rotate the rotating seat 13 of the center support 1. Rotating the rotating seat 13 will drive the center threaded rod 14 to rotate relative to the center threaded sleeve 15, so that the center threaded rod 14 rises (the initial state is the lowest height), thereby driving the rotating seat 13, the center connecting seat 11, and the center top rod 12 to rise to the specified height, so that the support height of the center support 1 is adjusted; at the same time, the rise of the center connecting seat 11 will drive the edge connecting seat 21 connected to it to rise through the connecting rod 3, thereby, the edge connecting seats 21 of all edge supports 2 are synchronously risen, and then drive the edge top rod 22 to rise synchronously, so that the support height of the edge support 2 is synchronously adjusted, and the support height of each support frame remains consistent during the adjustment process. Moreover, when the edge connecting seat 21 rises, the edge threaded rod 23 and the edge threaded sleeve 24 are driven to rise. At this time, the bottom of the edge threaded sleeve 24 is suspended in the air. Under the action of gravity, it will automatically rotate and descend. Finally, the bottom of the edge threaded sleeve 24 is supported on the surface of the substrate 100. At the moment of explosive welding, under the instantaneous impact force, the edge threaded rod 23 cannot rotate relative to the edge threaded sleeve 24 until it melts or burns. Therefore, the edge support 2 can provide a stable support effect after adjustment.

[0039] Preferably, the outer ring of the rotating seat 13 is formed with a dial 16 protruding from the central connecting seat 11 and the central threaded sleeve 15 to facilitate the rotation of the rotating seat 13.

[0040] Preferably, a counterweight 25 is provided at the bottom end of the edge threaded sleeve 24, and the thread lead angle between the edge threaded rod 23 and the edge threaded sleeve 24 is greater than 45°. The counterweight 25 can increase the gravity of the edge threaded sleeve 24, and cooperate with the thread with a large lead angle, so that when the bottom of the edge threaded sleeve 24 is suspended in the air, it can rotate and descend smoothly under the action of gravity.

[0041] Preferably, the central threaded rod 14 and the central threaded sleeve 15 are matched with fine-pitch threads, thereby achieving millimeter-level height adjustment.

[0042] In addition, the connecting rods 3 are all arranged horizontally and are of a freely retractable structure, thereby enabling adjustment of the support spacing.

[0043] Example 2

[0044] Recombination Figure 5 and Figure 6 As shown, a gap support mechanism for explosive welding of composite plates, the gap support mechanism includes:

[0045] a central support 1; and

[0046] A number of edge supports 2 are located around the central support 1. The edge supports 2 are connected to the central support 1 through connecting rods 3, so that the central support 1 and all the edge supports 2 form an integral structure. Here, the self-structures of the central support 1 and the edge supports 2 are the same as those in Embodiment 1, but there are eight edge supports 2. The central support 1 and all the edge supports 2 form a cross-shaped integral structure, and the distances between the central support 1 and the edge supports 2 and between adjacent edge supports 2 are equal. The integral structure is used to support between the substrate and the clad plate for explosion welding, and its support stability is greatly improved, and it will not affect the smooth discharge of the gas in the gap.

[0047] Similarly, when it is necessary to adjust the support height, the rise of the central connection seat 11 will drive the edge connection seat 21 connected thereto to rise through the connecting rod 3. At this time, the rise of the edge connection seat 21 will drive the edge connection seat 21 connected thereto to rise through the connecting rod 3. Thus, the edge connection seats 21 of all the edge supports 2 rise synchronously, and then drive the edge ejector rods 22 to rise synchronously, so that the support heights of the edge supports 2 are adjusted synchronously, and the support heights of each support frame remain consistent during the adjustment process.

[0048] In order to facilitate the adjustment of the support spacing, the gap support mechanism in this embodiment further includes an adjusting screw tube 4. The adjusting screw tube 4 horizontally penetrates through the central connection seat 11 and is rotatably matched with the central connection seat 11 (several annular protrusions can be provided on the outer wall of the adjusting screw tube 4 to be rotatably matched with the through holes of the central connection seat 11). The two ends of the adjusting screw tube 4 extend outwards, and two moving rods 5 are respectively threadedly connected to the two ends through opposite threads. The two moving rods 5 are aligned with two edge supports 2 located at one diagonal position of the "cross" integral structure and are fixedly connected to the edge connection seats 21 of the edge supports 2.

[0049] When it is necessary to adjust the support spacing, after placing the gap support mechanism on the surface of the substrate 100, just rotate the adjusting screw tube 4. The rotation of the adjusting screw tube 4 will drive the two moving rods 5 to move towards or away from each other, so as to drive the two edge supports 2 at the diagonal position to move towards or away from each other. Then, under the linkage effect of the connecting rod 3, it will drive all the edge supports 2 to move towards or away from each other synchronously, and during the movement, the distances between the supports always remain consistent, becoming larger or smaller synchronously.

[0050] Preferably, anti-slip threads 41 are provided on the outer wall of the pipe section where the adjusting screw tube 4 extends, which is convenient for rotating the adjusting screw tube 4.

[0051] Finally, it should be noted that the entire gap support mechanism of the present invention can be made of different alloy materials according to different explosion welding processes to ensure bonding quality. Preferably, the entire gap support mechanism can also be made of materials that vaporize in high-temperature environments, such as metal lead and zinc, which vaporize and discharge at the instant of high temperature generated by the explosion, thereby preventing residual support structure from affecting the bonding surface and improving bonding quality. Of course, other materials that can be instantly burned, such as wood, can also be used instead.

[0052] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that variations and improvements are possible without departing from the scope of the present invention, and all such variations and improvements fall within the scope of protection of the present invention.
