The working principle of this utility model is that by raising at least one roller to a certain angle, the deflection force exerted on the roller when the steel belt is tightened is decomposed horizontally, causing the roller assembly to generate a force component perpendicular to the direction of the steel belt, thereby automatically tightening the sealing steel belt while simultaneously tightening it, keeping it close to the forming cylinder wall. For example, the sealing steel belt 2 is wound around the first and second rollers in an S-shape.

[0032] For example, the Z-axis lifting mechanism used in the present invention can be a single-side drive structure or a double-side drive structure. When it is a single-side drive structure, and Figure 2 、 Figure 3 、 Figure 5 as well as Figure 7 The structure is the same as that of the Z-axis lifting mechanism, and the working method is also as described above, which will not be described in detail here; when the Z-axis lifting mechanism is a double-sided drive structure, there are two longitudinal openings, and the two longitudinal openings are symmetrically arranged on the side wall of the forming cylinder 1; the Z-axis lifting mechanism extends into the interior of the forming cylinder 1 from the two longitudinal openings and lifts and lowers along the axial direction of the longitudinal opening; the number of sealing steel belts 2 corresponds to the number of longitudinal openings and each is independently tightened and sealed on different longitudinal openings. For example, the Z-axis lifting mechanism of the double-sided drive structure can refer to the structure in the authorization announcement number CN 111054919B, which will not be described in detail here. Regardless of whether it is a single-sided drive structure or a double-sided drive structure, the additive manufacturing forming equipment provided by the utility model, especially the sealing steel belt tightening mechanism, can seal the sealing steel belt 2 on the longitudinal opening along the axial direction of the longitudinal opening to achieve the blocking or sealing of the longitudinal opening.

[0033] The Z-axis lifting mechanism used in the utility model is not different from the Z-axis lifting device used in the prior art, and exemplarily, the Z-axis lifting mechanism comprises an external cantilever lead screw structure 14 and a cantilever 13 connected with the external cantilever lead screw structure 14; the cantilever 13 extends into the inside of the forming cylinder 1 from the longitudinal opening and lifts along the axial direction of the longitudinal opening; the forming platform 6 is arranged on the cantilever 13 and moves synchronously with the Z-axis lifting mechanism.

[0034] The steel belt tensioning device 12 is arranged on the inner wall of the forming cylinder 1 or on the bottom of the forming cylinder 1; when the steel belt tensioning device 12 is arranged on the bottom of the forming cylinder 1, the additive manufacturing forming equipment further comprises a guide wheel 15 arranged in the inside of the forming cylinder 1; the sealing steel belt 2 is wound on the sealing steel belt tensioning mechanism and connected to the steel belt tensioning device 12 after being guided by the guide wheel 15.

[0035] The additive manufacturing forming equipment further comprises a pressing block 17 and a dustproof felt 3; the sealing steel belt 2 is fixedly arranged on the inner wall of the forming cylinder 1 through the pressing block 17; the dustproof felt 3 is arranged between the forming platform 6 and the sealing steel belt 2.

[0036] Exemplarily, referring to Figure 2 and Figure 3 , when the additive manufacturing forming equipment works, the forming platform 6 can lift under the action of the cantilever 13; the roller 5 device is installed in the forming platform 6, the roller 5 is fixed in the forming platform 6 through the guide rail 8, one side of the guide rail 8 is installed on the inclined pad 11, the roller mounting seat 10 is fixed on the sliding block 7, the two rollers 5 are connected through the roller connecting plate 4, the upper end of the sealing steel belt 2 is fixed above the wall of the forming cylinder 1, the sealing steel belt 2 is used for sealing the gap (longitudinal opening) left by the stroke of the cantilever 13 on the forming cylinder 1, the sealing steel belt 2 passes through the roller 5 in the forming platform 6 and is guided, and the sealing steel belt 2 is tensioned through the steel belt tensioning device 12 below the forming platform 6. When the steel belt is tensioned, the steel belt tension acts on the roller 5, so that the roller 5 generates a deflection force, the direction of the component force of the deflection force generated by the roller 5 is changed under the action of the inclined pad 11, the two rollers 5 will generate a horizontal component force under the action of the steel belt tension, and the component force is used for tightly pressing the steel belt to the wall of the forming cylinder 1, so that a better sealing effect is realized.

[0037] The technical scheme provided by the utility model will be described in detail below with reference to the drawings:

[0038] Referring to Figure 3, is a schematic diagram of the sealing steel belt tightening mechanism provided by the present invention when in use, that is, to achieve the internal sealing of the forming cylinder 1 of the SLM equipment. The internal lifting platform of the forming cylinder 1 is lifted and lowered by the external cantilever screw structure 14. The upper end of the sealing steel belt 2 is fixed by the pressure block 17. After that, the steel belt passes through the roller 5 of the forming platform 6 and is finally fixed to the steel belt tensioning device 12 under the action of the guide wheel 15. By adjusting the tension of the steel belt, the roller 5 on the slope presses the steel belt against the inner wall of the forming cylinder 1, thereby achieving the sealing of the metal powder 16 in the forming cylinder 1. By adding an inclined pad 11 with an angle of γ° under the roller 5 on one side, the horizontal component of the deflection force on the two rollers 5 is changed. The force analysis diagram of the deflection force is shown in the figure below. Figure 4 As shown:

[0046] See also Figure 5 The roller 5 in the roller connecting plate 4 can also adjust the slope position and the object of action so that the deflection force component of the roller 5 acts on the sealing steel belt 2 to achieve tightening. By placing the inclined pad 11 under the roller 5 near one end of the cantilever 13, a component force different from the structure shown in the scheme 1 can be generated. Under the same slope pad and other parameters, it can be calculated that Figure 5 The horizontal force that the solution can provide to the roller connecting plate 4 is greater than Figure 3 The horizontal force component that can be provided by the structure shown can be selected according to the tensioning capacity of the steel belt in actual use, so that the horizontal force component that can be obtained by the roller connecting plate 4 is within a suitable adjustment range.

[0047] By adding the angle of γ° inclined pad 11 under one side of the roller 5, the deflection force of the two rollers 5 in the horizontal direction is changed, and the force analysis diagram of the deflection force is shown as follows: Figure 6

[0055] Referring to Figure 7 , respectively, the bottom of the double roller 5 is added to the opposite position of the inclined pad, compared with the structure shown in Figure 3 and the structure shown in Figure 5 , under the same parameter condition, Figure 7 The structure shown in will provide greater horizontal component force to the roller connecting plate 4, and can provide greater range of tensioning force for the actual needs of the steel strip.
