Description
Technical Field
The utility model relates to a metal powder's isolated plant technical field.
Background
The flexible scraper has elasticity, makes its deformability better, and the cooperation manual adjustment is higher to the printing success rate of non-high accuracy part. At present, one side of the bottom of the section of a flexible scraper used by most printers is a right angle, and the other side of the bottom of the section of the flexible scraper is an inclined plane; and now mainly with the right-angled side of the flexible scraper in contact with the powder pile.
Due to the limitation of the SLM forming process, when a metal part is printed, a part which is suspended or has an insufficient self-growth angle needs to be additionally supported to play a role in heat conduction and fixation so as to assist the part forming; among them, the block support is one of the most commonly used support types. The block-shaped support is formed by combining two sheets in the mutually vertical direction, the sheets are obtained by laser single-pass scanning, the thickness is generally only about 0.2-0.3 mm, and the wall thickness is too thin, so that the block-shaped support is easy to warp after being scanned by a large-area block-shaped support, namely, a bulge is formed on the surface of the block-shaped support; consequently, current flexible scraper is during on cubic support upper berth powder, and when flexible scraper rectangular one side met the arch, flexible scraper took place the bending and hold power, and flexible scraper continues to remove, and flexible scraper resets fast under the elastic action of self after holding power and reaching a value, plays the powder promptly through flexible scraper, and then causes the interruption of shop's powder route, influences shop's powder effect.
SUMMERY OF THE UTILITY MODEL

1. in the scheme, when the scraper body meets a bulge in the process of spreading powder along the block support by the scraper body, the scraper body moves obliquely upwards under the action of the bulge through the second inclined plane due to the elasticity of the scraper body, namely the scraper body deforms and gives way; after the scraper body is enabled to bulge, the scraper body can stably reset under the elastic action of the scraper body, large-area powder cannot be bounced, normal powder laying is not affected, continuity of powder laying is guaranteed, and powder laying effect is guaranteed.
2. The both sides of this scheme scraper body are provided with first inclined plane and second inclined plane respectively, can strengthen the pliability of scraper body, and then avoid the damage of scraper body.
Further, the included angle between the second inclined plane and the horizontal plane is 45-65 degrees. Through the arrangement, the deformation and yielding of the scraper body are guaranteed, and the flexibility of the scraper body is also guaranteed.
Further, the included angle between the first inclined plane and the horizontal plane is 45-65 degrees. Through the arrangement, the flexibility of the scraper body is enhanced.
Further, the first inclined plane and the second inclined plane are symmetrically arranged along the center line of the scraper body. Through the arrangement, the whole structure of the scraper body is more stable, and the stress is more uniform.
Further, the included angle between the second inclined plane and the horizontal plane is 60 degrees. Through the arrangement, the flexibility of the scraper body is optimal.
Further, the middle part of the scraper body is transversely provided with a reinforcing plate. Through the arrangement, when the scraper body is deformed and retreats due to the protrusion, the damage caused by excessive deformation of the scraper body can be avoided through the reinforcing plate.
Further, the bottom both sides of reinforcing plate all are equipped with the block rubber, and the block rubber offsets with the scraper body. Through the setting, because the rubber block is flexible material, when the scraper body warp, can produce flexible reaction force to the scraper body through the rubber block, and then avoid the scraper body to warp excessively and cause the damage.
Further, a cavity is arranged in the scraper body, and the reinforcing plate penetrates through the cavity; and a supporting block is arranged between the side wall of the cavity and the reinforcing plate.
Through the arrangement, the positioning effect on the reinforcing plate can be enhanced through the supporting block, so that the stability of preventing the scraper body from being excessively bent is improved; and, reinforcing plate, supporting shoe and cavity lateral wall form the triangle-shaped structure, according to triangle-shaped stability, can improve the stability to the reinforcing plate location.
Furthermore, the supporting block is V-shaped, one end of the supporting block is fixedly connected with the supporting block, the other end of the supporting block is fixedly connected with the top in the cavity, and the turning part of the supporting block is fixedly connected with the side wall in the cavity.
Through the arrangement, the supporting blocks form two triangular structures in the cavity, and the stability of positioning the reinforcing plate can be improved according to the stability of the triangle.
Furthermore, the turning part of the supporting block extends out of the cavity, and a spring is arranged between the supporting block and the reinforcing plate.
Through the setting, the spring can play absorbing effect on the one hand, and on the other hand spring constitutes the triangle-shaped structure with reinforcing plate, scraper body, can improve the stability to the reinforcing plate location.
Drawings
FIG. 1 is a front view of a first embodiment of a scraper according to the present invention, which is suitable for forming a non-precision metal part;
fig. 2 is a cross-sectional view of the second main view direction of the embodiment of the scraper suitable for forming the non-precise metal piece of the present invention.
Detailed Description
The following is further detailed by way of specific embodiments:
reference numerals in the drawings of the specification include: the scraper comprises a scraper body 1, a first inclined surface 2, a second inclined surface 3, a reinforcing plate 4, a rubber block 5, a cavity 6, a supporting block 7 and a spring 8.
Example one
Substantially as shown in figure 1: the utility model provides a scraper suitable for molding of non-precision metalwork, includes flexible scraper body 1, and the bottom right side of scraper body 1 is provided with first inclined plane 2, and the bottom left side of scraper body 1 is provided with the second inclined plane 3 that is used for spreading the powder. The first inclined plane 2 and the second inclined plane 3 are symmetrically arranged along the center line of the scraper body 1, the included angle between the first inclined plane 2 and the horizontal plane is 60 degrees, and the included angle between the second inclined plane 3 and the horizontal plane is also 60 degrees.
The specific implementation process is as follows:
in the process of laying powder along the block-shaped support of the scraper body 1, when the scraper body 1 encounters a bulge, the scraper body 1 has certain stretching performance because the scraper body 1 is flexible and elastic; the scraper body 1 moves obliquely upwards under the action of the protrusion through the second inclined surface 3, namely the scraper body 1 deforms and retreats; after the scraper body 1 is protruded, the scraper body 1 can be stably reset under the elastic action of the scraper body 1, the powder material with large area can not be bounced, only the powder material with small parts on the surface can be bounced, the normal powder spreading is not influenced, the continuity of the powder spreading is ensured, and the powder spreading effect is ensured.
