[0028] The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0029] As shown in the drawings, the present application comprises a support frame 1, which is composed of cross beams and longitudinal beams made of profile steel, and three-layer frame bodies are constructed from bottom to top: bottom layer frame body 11, middle layer frame body 12 and top layer frame body 13, and layer panels 121 (for example) are fixedly laid on the bottom layer frame body 11 and the middle layer frame body 12, which are used to carry corresponding components. Figure 3 For example), which are used to carry corresponding components.

[0030] Universal wheel assemblies 16 are respectively installed at the four corners below the bottom layer frame body 11, and each universal wheel assembly 16 comprises a universal wheel and an adjustable support foot, the universal wheel facilitates the overall transfer of the tooling, and the support foot facilitates the overall support and fixation of the tooling to prevent sliding and vibration.

[0031] A spacing space is reserved between the bottom layer frame body 11 and the middle layer frame body 12, and some air sources and control components can be placed on the layer panel of the bottom layer frame body 11.

[0032] A plurality of placing tables 2 are fixedly arranged on the layer panel 121 of the middle layer frame body 12, and a downward pressing cylinder 4 is respectively fixed above each placing table 2 on the top layer frame body 13, the telescopic rod of the downward pressing cylinder 4 vertically downwardly faces the placing table, and a downward pressing block 3 is fixedly connected to the lower end of the telescopic rod; the curvature shape of the upper surface of the placing table 2 is consistent with the lower surface of the bulletproof plugboard 100, and the curvature shape of the lower surface of the downward pressing block 3 is consistent with the upper surface of the bulletproof plugboard 100.

[0033] AsFigure 1 As shown, the single-curved-surface bulletproof insert plate 100 is placed on each placing table 2 from bottom to top in turn, and when the bulletproof insert plate 100 of each group reaches the highest limit height, the telescopic rod of the downward pressing cylinder 4 is extended downward, the telescopic rod drives the downward pressing block 3 to press downward and press against the uppermost bulletproof insert plate 100, and a proper downward pressing force is maintained, so that the PE plate and the ceramic of the large number of bulletproof insert plates are pressed and connected, which can not only improve the bonding strength of the ceramic and thus improve the bulletproof performance, but also ensure the uniformity of the pressure and realize the stability of the bonding strength of the product.

[0034] In order to facilitate the prevention of the bulletproof insert plate 100 from being inclined and collapsed during the stacking process, improve the safety and stability, and also be applicable to the operation of different models of bulletproof insert plates 100 with the same arc but a certain deviation in length, and enhance the applicability of the tooling, the utility model also matches each placing table 2 with a set of self-adaptive constraint unit 5.

[0035] As shown in the figure, Figure 3 Each set of self-adaptive constraint unit 5 includes side support plates 51 vertically fixed on the left and right sides of the placing table 2, and a rear support plate 52 located on the rear side of the placing table 2 and fixed on both sides with the side support plates 51. Specifically, the bottom of the side support plates 51 on both sides is fixed with a reinforcing rib plate 57 through fastening bolts between the layer panel 121 of the middle layer frame body 12, so as to vertically fix the side support plates 51 on the layer panel 121 on the left and right sides of the placing table 2, and facilitate installation and disassembly. At the same time, the rear support plate 52 is fixed with the side support plates 51 on both sides, which enhances the firmness and stability of the vertical fixation of the side support plates 51 on the layer panel. Further, the bottom of the rear support plate 52 is also fixed with a reinforcing rib plate through fastening bolts between the layer panel 121 of the middle layer frame body 12, so as to further enhance the firmness and stability of the vertical fixation of the side support plates 51 on the layer panel.

[0036] In addition, the rear support plate 52 can also be used as a mounting base for nozzles and other components (not shown in the figure) to facilitate blowing and other operations towards the bulletproof insert plate during the pressing process, so as to accelerate the bonding and solidification.

[0037] Each side support plate 51 is matched with a side constraint plate 53 on the inner side direction (i.e. the direction towards the opposite side support plate 51). At least four guide columns 54 are matched between the side constraint plate 53 and the corresponding side support plate 51. One end of each guide column 54 is vertically fixed with the side constraint plate 53, the other end of the guide column 54 slides through the sliding sleeve on the side support plate 51, and the end is fixed with an anti-extrusion disc 51 to prevent the guide column from extruding. A spring 55 is sleeved on the guide column 54, and the two ends of the spring 55 abut against the side constraint plate 53 and the side support plate 51 respectively.

[0038] In the process of stacking the bulletproof insert plate 100 on the placing table 2 in turn, the two side constraint plates 53 are responsible for abutting and constraining the elastic force provided by the springs 55 on the two sides of the stacked bulletproof insert plate 100, so as to prevent the stacked bulletproof insert plate 100 from being skewed or even collapsed, and under the cooperation of the guide column 54 and the guide sleeve, it can be ensured that the side constraint plates 53 always remain vertical, that is, the side constraint plates 53 on the two sides always remain parallel, and the spacing between the upper and lower sides remains consistent; and under the combined action of the spring 55 and the guide column, the distance between the two side constraint plates 53 can be self-adaptively adjusted according to the length of the bulletproof insert plate 100, and a sufficient constraint force can be maintained; further, the existence of the anti-extraction disc 51 can prevent the guide column from being extracted, and can also limit the minimum distance between the two side constraint plates 53, that is, determine the minimum length of the bulletproof insert plate 100 that can be constrained during processing.

[0039] Of course, the elastic force of the spring 55 should not be too large to avoid unnecessary extrusion deformation of the bulletproof insert plate 100 clamped therein.

[0040] Further, in order to facilitate the insertion of the bulletproof insert plate 100 between the two side constraint plates 53, the front sides of the two side constraint plates 53 are respectively fixed with guide plates 56, and the two guide plates 56 form a horn-shaped opening with gradually increasing spacing from back to front, thereby facilitating the guidance of the bulletproof insert plate 100, so that it can be smoothly inserted between the two side constraint plates 53 and stacked on the placing table 2 in turn.

[0041] Further, in order to make the lower pressing block 3 automatically level when pressing the bulletproof insert plate, so that the lower surface of the lower pressing block 3 is tightly attached to the upper surface of the uppermost bulletproof insert plate, improving the stability of the pressing, the universal joint 41 is connected between the extension rod of the lower pressing cylinder 4 and the lower pressing block 3.

[0042] The cylinder assembly of the utility model is provided with a gas collecting block, a cylinder main switch, a digital gas pressure valve, a gas pipe and an air compressor (not shown in the figure) in addition to the lower pressing cylinder 4, the gas collecting block and the cylinder main switch are communicated with the air compressor through the gas pipe, the air compressor provides air power, the gas collecting block, the cylinder main switch and the lower pressing cylinder 4 are communicated through the gas pipe, the overall pressure of the single-curved-surface bulletproof insert plate 100 gluing tool is controlled, each lower pressing cylinder 4 is provided with a separate digital gas pressure valve, the digital gas pressure valve has the functions of air pressure display and air pressure adjustment, and the pressure can be effectively controlled.

[0043] The above only describes the preferred embodiment of the utility model, and does not limit the utility model, and any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
