Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1 to 5, an SLM forming platform with leveling function includes a forming base 1 provided with a groove 11, a plurality of elastic members, a forming base 3 and a plurality of fixing members 4; one end of the elastic piece is arranged in the groove 11, the other end of the elastic piece is connected with the forming base material 3, one end of the fixing piece 4 is movably connected to the forming base body 1, and the other end of the fixing piece is flatly pressed on the forming base material 3.

In the prior art, the flatness of the forming base material 3 is required to be about 60 micrometers, but the flatness of part of the forming base material 3 cannot meet the use requirement due to uneven levels of processing plants in various areas. The forming platform of the design relaxes the requirement on the flatness of the forming base material 3, so that more forming base materials 3 can meet the use requirement. And through the higher spill shaping base member 1 of surface smoothness, combine the degree of freedom of spring 2, when shaping substrate 3 surface smoothness is relatively poor, inside spring 2 can play the effect of adjustment, uses mounting 4 flattening shaping substrate 3 simultaneously to leveling efficiency has been improved greatly. In a specific embodiment, as shown in fig. 1 to 5, the dimensions of the forming base 1 and the forming base 3 are determined, the forming base 1 is produced to have a dimension of 120mm long, 120mm wide and 60mm thick, the groove 11 is formed with rounded edges, the groove 11 has a dimension of 112mm long, 112mm wide and 50mm thick, the array of springs 2 is arranged in the groove 11, the forming base 1 is produced to have a dimension of 110mm long, 110mm wide and 35mm thick, the forming base 1 is placed on the array of springs 2, and the forming base 3 is fixed on the forming base 1 by using the fixing member 4, so as to form a forming platform with a surface flatness meeting the standard. If the forming platform of the present application is not used, the utilization rate of the forming substrate 3 will be greatly reduced based on the selection criteria for the forming substrate 3.

Further, the elastic array uses an elastic member, which is a spring 2. The spring 2 is an elastic object that stores mechanical energy. The spring 2 is typically made of spring steel. The elasticity of the device can be used for controlling the movement of the machine parts, relieving impact or vibration, storing energy, measuring the force and the like; the method is widely applied to machines and instruments. The spring array is used for adjusting flatness, so that the spring 2 with high degree of freedom is selected as the elastic member, and the spring 2 is fixed at the bottom of the groove 11 by welding.

Further, as shown in FIG. 2, the molded base 1 had a length of 120mm, a width of 120mm and a thickness of 60 mm. The size of the forming base body 1 is determined to be matched according to the size of the forming base material 3, the size of the spring 2 and the size of the groove 11, and the size of the conventionally used forming base material 3 is mostly about 100mm in length, 100mm in width and 35mm in thickness, the spring 2 is about 15mm in thickness, and the groove 11 is about 50mm in thickness; the thickness of the groove 11 is designed to weld the spring 2 at the bottom of the groove 11. Therefore, the molded substrate 1 is designed to have a length of 120mm, a width of 120mm and a thickness of 60 mm.

Further, as shown in fig. 2, a groove 11 is designed in the molding base 1, edges of the groove 11 are designed to be rounded, and edges of the groove 11 are designed to be rounded, so that the matching degree of the groove 11 and the molding base 3 is higher.

In one embodiment, the elastomeric array is a 5 x 6 lattice, as shown in fig. 3. The number of the springs 2 is determined based on the size of the molding base 3 and the molding base 1, and when the molding base 1 has a length of 120mm, a width of 120mm and a thickness of 60mm, as shown in fig. 4, the molding base 3 has a length of 110mm, a width of 110mm and a thickness of 35mm, and the groove 11 is designed to be slightly larger than the molding base 3 in size to serve as a support since the groove is designed to accommodate the molding base 3. The groove 11 has the size of 112mm in length, 112mm in width and 50mm in thickness; based on the data size, in order to solve the problem of flatness of the forming platform, the bearing force and the bearing area of each spring 2 are reasonably distributed, and the elastic array is designed to be a 5 x 6 lattice. Because the sizes of the molding base 1 and the molding base 3 are not fixed, the number of the lattices of the elastic array needs to be determined according to actual production and use.

In a specific embodiment, as shown in fig. 5, there are 4 fixing members 4. The fixing member 4 is formed by flattening the formed base material 3 with low flatness to meet the use standard. The fixing piece 4 is provided with a hole and is connected with the forming base body 1 through a screw, one end of the fixing block is attached to the forming base body 1, and the other end of the fixing block is attached to the forming base material 3. Because the flatness of the forming base material 3 is high, in order to achieve a balanced and flat state of the fixing member 4, the other end of the fixing member 4 applies pressure on the forming base material 3 with low flatness, and the internal spring 2 is deformed by the pressure to balance the whole system. Therefore, the flatness of the forming platform meets the actual working requirement.

In summary, an SLM forming platform with leveling function is specifically to place an indefinite number of springs 2 in a high-flatness forming base body 1 provided with a groove 11, place a forming base material 3 on the springs 2 and fix with a fixing member 4, and adjust the flatness of the forming platform through the springs 2 and the fixing member 4; the application universality is strong, the workload of workers is greatly reduced, the utilization rate and the leveling efficiency of the forming platform are improved to a certain extent, the waste behavior caused by the fact that the manufacturing quality of the forming base material 3 is not too high is avoided, and the working cost is also saved.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
