Detailed Description
The following description of the embodiments according to the present invention is made with reference to the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, however, the present invention may be practiced in other ways than those specifically described herein, and the present invention is not limited to the specific embodiments disclosed below.
Additive manufacturing is a technique that uses various materials to print a component layer by layer based on a digital model file. It is often used in the fields of mold manufacturing, industrial design, and the like. Compared with a casting process, the material increase manufacturing technology is adopted to process the runner with the characteristics of small size, thin wall thickness, bent structure and the like, so that the rejection rate of runner parts can be reduced, and the size precision of the runner parts can be improved.
At present, the flow passage part can be processed at one time by adopting an additive manufacturing technology. However, the number of the runner parts to be processed at one time is only one, so that the three-dimensional model of the runner part needs to be introduced again before each processing, and operations such as slicing and layering are performed, so that the production efficiency of the runner part is low. In order to solve the problem of low production efficiency of the runner parts, a plurality of runner parts can be processed and formed at one time. Different from a runner part processed at one time, when a plurality of runner parts are processed at one time, a cutting reserved part with certain specification is formed between two adjacent runner parts, so that after the plurality of runner parts are formed, cutting needs to be carried out at the cutting reserved part, and the plurality of runner parts are separated.
However, the strength of the cutting reserved part formed between two adjacent runner parts is high, so that the cutting resistance is high, the cutting difficulty is high when the adjacent runner parts are cut and separated, and the runner parts are easy to damage.
The technical problems that when a plurality of runner parts are machined at one time by the aid of an additive manufacturing technology, the machined runner parts need to be cut and separated, cutting difficulty is high, the runner parts are prone to damage, and rejection rate is increased are solved.
As shown in fig. 1 and 2, an embodiment of the present invention provides a flow channel assembly. The runner assembly includes: at least two flow channel structures 1, a cutting structure 2 and a pressure reducing structure 3 are reserved. The reserved cutting structure 2 is arranged between two adjacent flow passage structures 1. The pressure relief structure 3 is formed on the preliminary cutting structure 2. It is to be understood that the pressure relief structure 3 may be formed inside the reserved cutting structure 2, or may be formed at the outer circumference of the reserved cutting structure 2.
The following describes an actual cutting process of the flow channel assembly provided by the embodiment of the present invention, taking the flow channel assembly including two flow channel structures 1 as an example. It should be understood that the flow channel assembly includes, from bottom to top, a first flow channel structure, a reserved cutting structure 2, a second flow channel structure, and a pressure relief structure 3 formed on the reserved cutting structure 2. The reserved cutting structures 2 are respectively connected with the first flow channel structure and the second flow channel structure.
In order to obtain the first flow channel structure and the second flow channel structure which are separated from each other and have high forming precision, under the action of the pressure reducing structure 3 formed by the reserved cutting structure 2, the cutting tool cuts the reserved cutting structure 2 under small resistance, so that the first flow channel structure and the second flow channel structure are completely separated.
According to the structure and the actual cutting process of the flow channel assembly provided by the embodiment, the reserved cutting structure 2 is arranged between the two adjacent flow channel structures 1, and the pressure reducing structure 3 formed on the reserved cutting structure 2 can reduce the structural strength of the reserved cutting structure 2. After a plurality of runner structures 1 are processed at one time, linear cutting can be carried out at the reserved cutting structure 2, the cutting resistance of a cutting tool can be reduced under the action of the pressure reducing structure 3, the cutting difficulty is reduced, and the runner structures 1 which are separated from each other and have complete structures are easy to obtain.
As a possible realization, the reserved cutting structure 2 has a neutral plane. The pressure reducing structure 3 is arranged on the neutral surface of the reserved cutting structure 2. It should be understood that the neutral plane of the reserved cutting structure 2 is a plane where the balance point is located, and when the cutting tool performs linear cutting on the neutral plane of the reserved cutting structure 2, the cutting force applied to the flow channel assembly is relatively balanced, so that the structural integrity of the flow channel structure 1 in the linear cutting process can be further ensured. When the decompression structure 3 is arranged on the neutral surface of the reserved cutting structure 2, the cutting tool cuts the neutral surface of the reserved cutting structure 2, so that the molding precision of the flow channel structure 1 can be further improved, the cutting resistance is reduced, and the flow channel structures 1 separated from each other are easily obtained.
As a possible realization, the pressure reducing structure 3 is a hollow structure provided on the reserved cutting structure 2. When the material increase manufacturing technology is adopted and the hollow part of the decompression structure 3 is manufactured, the hollow part is not required to be molded and manufactured, the waste of material powder is avoided, and the production cost is saved. Meanwhile, the whole weight of the flow channel assembly can be reduced, and the flow channel assembly is convenient to carry when the cutting and separating operation is carried out subsequently.
In an alternative way, as shown in fig. 3, when the pressure reducing structure 3 is a hollow structure, the hollow structure is at least one set of through holes 31 opened on the reserved cutting structure 2. The through hole 31 is a through hole in a broad sense, and the cross-sectional shape in the radial direction thereof may be a circle, a semicircle, a rectangle, an ellipse, or the like, which is not listed here.
The sets of through holes 31 are distributed along the height direction of the reserved cutting structure 2. The axis of each set of through holes 31 is parallel to the neutral plane of the reserved cutting structure 2. Each set of through holes 31 is distributed along the circumference of the reserved cutting structure 2. At this moment, cutting tool cuts in a plurality of planes department on reserving cutting structure 2, all can reduce the cutting resistance under decompression structure 3's effect, reduces the cutting degree of difficulty.
When the pressure reducing structure 3 is formed on the neutral surface of the reserved cutting structure 2, the plane of the neutral surface of the reserved cutting structure 2 penetrates through the group of through holes 31. At this time, when the reserved cutting structure 2 is cut, the through hole 31 does not need to be partially cut, and the cutting resistance is reduced. And, the granule slagging scorification that drops to cutting structure 2 is reserved can be discharged through-hole 31, can further reduce the cutting degree of difficulty.
In one example, as shown in fig. 2, when the cross section of the at least one set of through holes 31 in the radial direction is approximately semicircular, the inner side wall of the at least one set of through holes 31 includes a flat surface portion 311 and a curved surface portion 312 surrounding the through holes 31 in the circumferential direction of the through holes 31. The neutral plane of the reserved cutting structure 2 is in the same plane with the plane portion 311 included in the inner side wall of the at least one set of through holes 31. At this time, the cutting tool cuts along the plane where the plane portion 311 of the through hole 31 is located, the area of the reserved cutting structure 2 that needs to be cut by the cutting tool is minimized, and the cutting resistance can be further reduced.
Exemplarily, on the premise of saving material powder, in order to further ensure that the flow channel structure 1 is not damaged by the cutting and separating operation, the height of the reserved cutting structure 2 is set to be 3mm to 4 mm. The height of the reserved cutting structure 2 is the same as the height direction of the flow channel structure 1. And, the height of the at least one through hole 31 provided in the reserved cutting structure 2 is 2mm to 3mm, and the width of the plane portion 311 of the at least one through hole 31 is 2.5mm to 4 mm. The height direction of the at least one through hole 31 is the same as the height direction of the flow channel structure 1. The width direction of the at least one through hole 31 is perpendicular to the height direction of the flow channel structure 1.
In one example, as shown in fig. 1, the axes of the same set of through holes 31 intersect the axis of the reserved cutting structure 2 at a point. At this time, the axes of the set of through holes 31 are located in the same plane, and their intersection points intersect with the axis of the preliminary cutting structure 2, so that the flow channel assembly has high symmetry. Based on this, when utilizing the cutting stage property to reserve cutting structure 2 and cutting, can guarantee that the cutting force that the runner subassembly received is comparatively balanced, avoid runner structure 1 to damage.
When the neutral plane of the reserved cutting structure 2 is in the same plane as the plane portion 311 included in the inner side wall of at least one set of through holes 31, if the axis of the same set of through holes 31 intersects the axis of the reserved cutting structure 2 at a point. At this time, the cutting tool does not need to cut the hollow portion of the through hole in the neutral plane range, and cutting resistance can be reduced. And, the cutting tool cuts at the neutral plane of the reserved cutting structure 2, so that the stress of the runner assembly is balanced during the cutting operation.
Illustratively, as shown in fig. 1, the pressure relief structure 3 includes a set of through holes 31, and the set of through holes 31 includes 12 through holes 31, and axes of the 12 through holes 31 are located on the neutral plane of the reserved cutting structure 2 and intersect with the axis of the reserved cutting structure 2 at a point, that is, the 12 through holes 31 are uniformly distributed on the neutral plane of the reserved cutting structure 2 in a radial manner.
To further reduce the cutting resistance, the at least one set of through holes 31 comprises a plurality of through holes 31 communicating with each other. At this moment, the cutting tool cuts the reserved cutting structure 2 and the dropped particle slag can be discharged out of the reserved cutting structure 2 through the through holes 31 which are communicated with each other, so that the cutting difficulty can be further reduced.
In one example, the pressure relief structure 3 further comprises at least one set of communication grooves 32 opening in the reserved cutting structure 2.

The communication grooves 32 in the same group and the communication grooves 32 in the two groups are communicated through the through holes 31.
As shown in fig. 1 and 4, when the communication grooves 32 are U-shaped grooves, the height of the communication grooves 32 in the extending direction of at least two flow channel structures 1 is 2mm to 3mm, the width of the communication grooves 32 in the direction perpendicular to the extending direction of at least two flow channel structures 1 is 2.5mm to 4mm, at least one set of the communication grooves 32 includes at least two communication grooves 32, and the distance between two adjacent communication grooves 32 is 4mm to 6 mm. Of course, the specification, number and arrangement of the communication grooves 32 can be set according to actual conditions.

It is understood that the volume occupied by the pressure-reducing structure 3 within the reserved cutting structure 2 can be increased regardless of whether the pressure-reducing structure 3 includes the communication groove 32 or the communication hole 33. Based on this, the volume that cutting tool cut reserved cutting structure 2 is littleer, has further reduced the cutting degree of difficulty.
