The powder and cutting bits separating and collecting device of the additive and subtractive composite processing system in combination with the illustrated exemplary embodiment includes a processing platform, a base plate, a switchable channel, a switching assembly for switching the channel, a powder collecting barrel, and a cutting bits collecting barrel. Which basically forms the basis of additive manufacturing, i.e. shaping a workpiece on a substrate by means of a laser additive manufacturing process.

In the course of working, under additive manufacturing operating condition, changeable passageway is set up at the powder collecting channel, and the lower part and the powder collecting vessel intercommunication of powder collecting channel, and unnecessary powder on the processing platform 100 falls in the powder collecting vessel through the collection portion of processing platform bottom, in the powder collecting vessel is fallen in the nature via the powder collecting channel, realizes retrieving additive manufacturing's powder.

When the material-reducing composite processing system is switched to the material-reducing working mode, the switchable channel is switched to the cutting scrap collecting channel through the switching assembly, the lower part of the cutting scrap collecting channel is communicated with the cutting scrap collecting barrel, therefore, the cutting remnants machined by the material-reducing on the processing platform 100 fall through the collecting part at the bottom of the processing platform and naturally fall into the cutting scrap collecting barrel through the cutting scrap collecting channel, and the collection of the cutting remnants in the material-reducing process is realized.

Therefore, the separation and collection device of the whole material increase and decrease composite processing system shares a processing platform and the collection part at the bottom, and the outlet end of the collection part is connected to the powder collection channel or the cutting scrap collection channel through the switchable channel at the bottom, so that separation and collection are realized. That is, during additive manufacturing processing, powder is collected by a separate powder collection channel; in the material reducing manufacturing process, cutting scraps are collected through an independent cutting scrap collecting channel, so that the situation that powder and the cutting scraps are mixed and fall onto a processing platform to cause a processing plane to be dirty and messy is avoided, meanwhile, the situation that redundant powder and oblique cutting scraps are mixed together to be collected is avoided, and the powder cannot be recycled.

The powder and cutting chips separating and collecting device for the additive/subtractive composite machining system, which is shown in fig. 1, is designed to collect powder in the additive machining mode and separate and collect excess powder and cutting chips in the subtractive machining mode in the additive composite machining system.

The additive and subtractive composite processing system of the present invention is particularly a composite processing system combining at least one additive manufacturing device and at least one subtractive manufacturing device, wherein a part is processed by layer-by-layer deposition based on the additive manufacturing system, the material of the part may be, for example, metal powder or alloy powder such as stainless steel, titanium alloy, aluminum alloy, and nickel-based alloy, and the additive manufacturing system may be a powder feeding (coaxial powder feeding or paraxial powder feeding) laser additive manufacturing system or a powder spreading additive manufacturing printing system; on the basis of the part of additive machining, direct cutting machining is carried out through a cutting tool of a material reduction manufacturing system. The additive and subtractive composite machining system of the present invention is generally a laser additive manufacturing system and a feeding (powder) mechanism integrated in a CNC machining center.

The powder and cutting chips separating and collecting apparatus for the additive and subtractive composite machining system as illustrated in fig. 1 and 2 includes a machining platform 100 and a base plate 200. The substrate 200 may be mounted to the processing platform 100, such as clamped with a clamping mechanism, as a substrate required for additive manufacturing. For example, based on a powder fed additive manufacturing deposition process, a part is machined by layer-by-layer deposition on the substrate 200.

In the embodiment of the present invention, with reference to the adjustment schematic diagrams of the fast clamping tool assemblies shown in fig. 3A and 3B, a set of fast clamping tool assemblies is respectively disposed on two sides of the processing platform 100, and the fast clamping tool assemblies on the two sides are used to rapidly clamp substrates with different sizes/shapes.

For example, the fast clamping tool assembly as an alternative embodiment is designed to be a design capable of adjusting the size of the web, and each group of fast clamping tool assemblies with variable web comprises a fixed stop 20 arranged at the end of the processing platform 100 and a movable stop 10 arranged in parallel with the fixed stop, wherein the fixed stop 20 is configured to be fixed to the end position of the edge of the processing platform in a manner of keeping the position of the processing platform fixed, for example, by welding, bolt fastening, and the like. Referring to fig. 1, the space between the movable stoppers 10 corresponding to the two sets of quick clamping tool assemblies forms a clamping space of the substrate 200.

As shown in fig. 1 and 2, the movable stopper 10 and the fixed stopper 20 may be selected from a regular square shape, which is beneficial for stable and reliable clamping of the substrate 200.

Preferably, two sets of quick clamp tooling assemblies are provided at two opposite ends of the upper surface of the tooling platform 100 and are split to the same structural design. Two sets of quick clamp tool assemblies are symmetrically arranged about a central axis of the machining platform.

In the example shown in fig. 1 and 2, a connecting rod 12 is disposed between each set of the movable stoppers 10 and the fixed stopper 20, one end of the connecting rod is fixedly connected to the movable stopper 10, and the other end of the connecting rod passes through the fixed stopper 20 and extends out and is connected to a clamping operation portion 18. The connecting rod 12 is sleeved with an elastic restoring mechanism 14, and the elastic restoring mechanism 14 is located between the fixed stopper 20 and the movable stopper 10 and has a tendency to make the movable stopper 10 move toward the other side of the processing platform 100.

As an alternative example, the elastic return means 14 comprise a spring assembly with a certain pre-tension for having the movable stop 10 a tendency to move towards the other end of the processing platform.

For example, in the example shown in fig. 1 and 2, the spring assembly has at least one spring sleeved on the connecting rod 12, and when the substrate 200 is clamped between the movable stoppers 10 of the two sets of quick clamping tool assemblies, the two movable stoppers 10 are caused to clamp the substrate 200 at least partially by means of the elastic force provided by the spring.

In other embodiments, the spring assembly may be disposed between the movable block 10 and the fixed block 20 in other manners, such as a plurality of spring nesting structures with different diameters, a plurality of springs in series and/or parallel, and a plurality of springs disposed between the movable block 10 and the fixed block 20, so as to clamp the substrate 200 between the movable blocks 10 by applying a pre-load to the movable blocks 10.

As shown, the clamping operation portion includes a handle for an operator to operate, such as a holding portion, and particularly, an ergonomic holding portion designed to facilitate finger holding. During clamping of the substrate 200, an operator can operate the clamping operation portion to pull the clamping operation portion outward in a direction away from the processing platform 100, overcome the pre-tightening force provided by the spring assembly, so that the movable stoppers 10 move toward the two ends of the processing platform, place the substrate 200 in the empty space between the two movable stoppers 10, release the clamping operation portion to clamp the substrate 200, and keep the substrate 200 in a centered position with respect to the processing platform 100, thereby achieving centering alignment and clamping of the substrate 200.

With reference to fig. 3A and 3B, based on the design of the quick clamping tool assembly of the foregoing embodiment, quick clamping of substrates with different widths can be achieved, for example, clamping of the substrate 200 with a width D as described in fig. 2A and a width D as shown in fig. 3B.

As shown in fig. 1, 2 and 3A and 3B, the maximum clampable size D of the quick clamping tool assembly depends on the customized maximum size of the web, and the minimum clampable size D depends on the ultimate tension size of the spring assembly, wherein D < D.

The powder and cutting debris separating and collecting apparatus of the example shown in fig. 1 further includes collecting portions provided at the bottom of the processing platform 100 at positions on both sides of the substrate. Wherein the collecting part is arranged in the vicinity of the fixed stop 20 of the processing platform and in a direction closer to the center of the processing platform than the fixed stop.

As shown in fig. 1, the collecting portion includes a first collecting portion 31 and a second collecting portion 32, which are used for collecting excess powder generated by the additive machining and cutting chips generated by the subtractive machining.

The first collecting part 31 and the second collecting part 32 are of the same structural design and are arranged symmetrically with respect to the central axis of the processing platform. The inlets of the collecting ends of the first collecting portion 31 and the second collecting portion 32 are connected to the bottom of the processing platform 100.

It should be understood that a penetration portion, such as a powder overflow port, is provided at a position on the processing platform 100 corresponding to the inlets of the collecting ends of the first collecting portion 31 and the second collecting portion 32, and communicates with the inlets of the collecting ends of the first collecting portion 31 and the second collecting portion 32. In an alternative embodiment, the chips fall down to the collecting portion via the through portion.

As shown in fig. 1, the first collecting portion 31 and the second collecting portion 32 are disposed at an angle to the bottom of the processing platform, facilitating the falling of the powder and the chips. Alternatively, the included angle between each of the first collecting part 31 and the second collecting part 32 and the bottom of the processing platform 100 is controlled within a range of 15 ° to 170 °, that is, the first collecting part 31 and the second collecting part 32 are installed at the bottom of the processing platform 100 in an inclined manner as far as possible.

In order to save space, the first collecting part 31 and the second collecting part 32 are both located below the processing platform and are constrained within the range of the processing platform, and the included angle between the first collecting part 31 and the bottom of the processing platform 100 and the included angle between the second collecting part 32 and the bottom of the processing platform are controlled within the range of 20-90 °. In the example of the present invention, the angle a is controlled to be in the range of 30 ° to 45 °, which is advantageous for the following channel switching.

As shown in fig. 1 and 2, the powder and chips separating and collecting apparatus further includes a switchable passage disposed below the processing platform 100 and in operable switching communication with the outlet end of the collecting portion.

In the example of fig. 1, the switchable passages include a powder collecting passage 81 for collecting powder and a chip collecting passage 82 for collecting chips. The powder collecting channel 81 and the cutting chip collecting channel 82 are arranged independently of each other, i.e., the inlet and outlet of the two channels and the path defined by the channels are arranged independently of each other.

In an alternative embodiment, both the powder collecting channel 81 and the cutting chip collecting channel 82 are configured to be formed via separate housings. It should be understood that the housing may be made of a strong, corrosion-resistant housing, such as stainless steel, ceramic, etc.

As shown in fig. 1, a powder collecting tub 91 and a cutting chip collecting tub 92 are further provided at the bottom of the collecting device.

And a powder collection barrel 91 communicating with the powder collection passage 81.

The cutting chip collection bucket 92 communicates with the cutting chip collection passage 82.

In an alternative embodiment, the powder collection bucket 91 is removably disposed below the powder collection channel 81. A cutting chip collection bucket 92 is removably disposed below the cutting chip collection passage 82.

In the embodiment of fig. 1, a switching assembly for switching the channels is provided in association with the switchable channels, which has at least one switching portion, such as a pivotable flap 50 as shown in fig. 1, the flap 50 being arranged to be switchably connected to the first collecting portion 31 or the second collecting portion 32. Thereby, the shutter 50 is operated to be switchably connected to the collecting portion, as shown in fig. 4A and 4B, to switch between the powder collecting passage 81 and the cutting chip collecting passage 82.

As shown in connection with fig. 4A and 4B, by switching operation of the baffle 50, for example, in the additive manufacturing mode, the baffle 50 may be operated to at least one second position as shown in fig. 4B, in connection with fig. 1, i.e., in abutment with the second collecting portion 32 located on the right side, in particular, in abutment with the outlet end of the second collecting portion 32, the baffle 50 closes the cutting chip collecting channel 82, thereby establishing a powder recovery path from the collecting portion to the powder collecting channel 81.

It should be understood that, in connection with the position switching schematic of the baffle 50 shown in fig. 4B, the baffle 50 is separated from the first collecting portion 31, thereby realizing that a complete powder collecting path is formed from the first collecting portion 31, the second collecting portion 32 to the powder collecting channel 81 and the powder collecting barrel 91.

As shown in fig. 1 and 4B, the first collecting portion 31 and the second collecting portion 32 disposed from the two ends of the processing platform 100 can both collect the excessive powder in the additive manufacturing process, and fall into the powder collecting channel 81 through the first collecting portion 31 and the second collecting portion 32, and further fall into the powder collecting barrel 91, so as to recover and collect the powder.

As shown in fig. 1 and 4B, when the additive/subtractive composite machining system is switched to the additive/subtractive manufacturing mode, the baffle 50 is operated to be switched to at least one first position, for example, to be abutted against the left first collecting portion 31, particularly against the outlet end of the first collecting portion 31, and the baffle 50 closes the powder collecting passage 81, thereby establishing a cutting chip collecting path from the collecting portion cutting chip collecting passage 82.

It will be appreciated that in connection with the position switching illustration of the baffle 50 shown in fig. 4B, the baffle 50 is separated from the second collection portion 32, as shown by the position of switchable manipulation indicated by the dashed lines, thereby achieving that a complete chip collection path is formed from the first collection portion 31, the second collection portion 32 to the chip collection channel 82 and the chip collection bucket 92.

As shown in fig. 1 and 4B, the first collecting portion 31 and the second collecting portion 32 disposed at both ends of the machining platform 100 can collect the cutting chips generated in the manufacturing process of the material reducing device, and the cutting chips fall into the cutting chip collecting channel 82 through the first collecting portion 31 and the second collecting portion 32, and further fall into the cutting chip collecting bucket 92, so as to collect the cutting chips.

As shown in fig. 1, in the switching process, the first collecting portion 31 is located on the same side as the powder collecting passage 81 and the powder collecting barrel 91, and the second collecting portion 32 is located on the same side as the cutting chip collecting passage 82 and the cutting chip collecting barrel 92.

In other embodiments, the positions of the powder collecting channel and the powder collecting barrel, the positions of the cutting chip collecting channel and the positions of the cutting chip collecting barrel can be set to be other positions, and the switching assembly is correspondingly controlled to realize the construction and switching of the corresponding collecting path under different working modes.

As shown in fig. 1, the powder collecting channel 81 and the cutting chip collecting channel 82 are respectively located at both sides of the switching assembly and symmetrically distributed for easy assembly and space saving and for switching of the channels.

In an alternative embodiment, the switching member may be provided with an operating portion for operating the position switching of the baffle 50 so as to be connected to the first collecting portion 31 or the second collecting portion 32.

In the example shown in fig. 1, the manipulation portion may be a knob 40 that is manually operable to effect switching of the position of the shutter 50. Thus, in the additive manufacturing processing mode or the subtractive manufacturing processing mode, the switching operation can be manually performed by the operator.

It should be understood that in various embodiments of the present invention, the shutter 50 and its rotating shaft 51 and operating portion may be mounted on a bracket below the processing platform or on a separate supporting frame (not shown) to realize the switching control of the shutter.

In an alternative embodiment, the support bracket may be centrally located between the two channels.

In other embodiments, the operation portion for operating the position switch of the baffle 50 may be an actuator driven by a driving source, and the driving source may be one of an air source, a hydraulic cylinder, or a motor. Thus, the actuator drives the shutter 50 to rotate, thereby switching the positions.

The actuator is particularly a component which can be driven by a driving source to act so as to drive the baffle 50 to rotate to realize position switching.

For example, in an example using a motor as a driving source, the actuator may be a speed change and/or direction change mechanism connected to the motor, connected to the rotary shaft of the flapper, so as to achieve rotational driving of the rotary shaft.

In another embodiment, for example, in an example in which a hydraulic cylinder is used as the drive source, the actuator may be a direction changing mechanism connected to a hydraulic piston rod of the hydraulic cylinder, connected to the rotary shaft of the flapper, and converting a linear motion of the hydraulic piston rod in the axial direction thereof into a rotary motion, thereby achieving rotary drive of the rotary shaft.

In the example of the present invention, the air supply driving is taken as an example, and as shown in fig. 2, the manipulating portion for operating the shutter is pneumatically operated by the air supply. As shown in fig. 1, the operating unit includes a cylinder block 61 and a cylinder rod 62, and the cylinder rod 62 is located in the cylinder block 61. Thus, the air pump 70 provided at the lower portion can drive the cylinder piston rod 62 to move up and down.

One end of the cylinder piston rod 62 is connected with a direction changing mechanism (not shown) and is connected with the rotating shaft 51 of the baffle 50, so that the linear motion of the cylinder piston rod 62 along the axial direction is converted into the rotating motion, thereby realizing the rotating drive of the rotating shaft, and meanwhile, the baffle 50 can be butted to the first collecting part 31 or the second collecting part 32 at a certain angle when being butted to the first collecting part 31 or the second collecting part 32 through the downward pulling of the cylinder piston rod, namely, the baffle 50 is butted to the first collecting part 31 or the second collecting part 32 at an inclined angle, thereby being beneficial to the falling of the cutting chips or the powder.

It should be understood that the air pump 70 is a dual-purpose air pump and is configured with a controller, and is used for controlling the working state of the air pump, i.e. the air pumping or air blowing state, according to the working state of the material-increasing and material-decreasing combined machining system, so as to drive the piston rod of the air cylinder, and further realize the switching control of the state of the baffle plate.

In various alternative embodiments, when the baffle 50 is switched to be connected to the first collecting portion 31 or the second collecting portion 32, the included angle formed by the baffle 50 and the first collecting portion 31 and the included angle formed by the baffle 50 and the second collecting portion 32 are both greater than or equal to 180 °, so that the butt joint of the inclined angles is facilitated, and the natural falling of the powder or the cutting scraps is facilitated.

In the example shown in fig. 1, the switching member is designed as a single baffle plate, and the powder collecting passage and the cutting chip collecting passage are switched. In a further embodiment, the switching member can also be designed with two pivotable flaps, wherein a first flap is provided to be switchably connected to the first collecting section and a second flap is provided to be switchably connected to the second collecting section.

The first collecting part, the first baffle, the powder collecting channel and the powder collecting barrel are positioned on the same side, and the second collecting part, the second baffle, the cutting chip collecting channel and the cutting chip collecting barrel are positioned on the same side.

Thereby, the separating and collecting device of the powder and the cutting chips is set to be operable in a separating and collecting state or a closed state, wherein:

in the first separated collection state, the first baffle is operatively connected to the first collection portion, the second baffle is separated from the second collection portion, and a cutting chip collection path is established from the collection portion to the cutting chip collection passage and the cutting chip collection barrel, corresponding to a subtractive manufacturing process mode;

in a second separated collection state, the second baffle is operatively connected to the second collection portion, the first baffle is separated from the first collection portion, a powder collection path is established from the collection portion to the powder collection channel and the powder collection bin, corresponding to an additive manufacturing process mode,

in the closed state, the first baffle is operatively connected to the first collecting portion, and the second baffle is operatively connected to the second collecting portion, closing the cutting chip collecting channel and the powder collecting channel, thereby facilitating transfer and replacement of the collecting bucket.

In the embodiment shown in fig. 1, the switching member has a manipulating portion for manipulating the positions of the first shutter and the second shutter, for example, a manual manipulation knob for switching the shutter positions, and is disposed corresponding to the first shutter and the second shutter, respectively.

Although the invention has been described with reference to preferred embodiments, it is not intended to be limited thereto.
