The soft materials of the present invention include, but are not limited to, soft rubber, foam board, sponge, soft polyurethane, silica gel, soft glass, etc., which can be processed by common machine tools using common various machine tools 1, and also can be processed by thermal cutting.

In the present invention, for convenience of explanation, a sponge material is described as a specific soft material.

The sponge has wide application range, such as an earphone sponge sheath used on a walkman, a sponge pillow and a sponge cushion used in home, offices and vehicles, a sound insulation sponge used on an automobile and the like, and has different requirements on the appearance of the sponge in different application occasions.

Example 1

Referring to fig. 1 (a) and 1 (b), the sponge HM1 as a raw material or before processing is annular, and the turning portion of the sponge of the annular raw material as a whole is smoothly transitioned. The sponge body as the raw material has a rectangular cross section.

Referring to fig. 2 (a) and 2 (b), the sponge HM2 after the processing is expected to be also annular, and the turning of the sponge is smoothly transited. The peripheral surface of the cross section of the processed sponge HM2 includes an upper portion HM2-1, a side portion HM2-2 and a lower portion HM2-3. Wherein, the upper part HM2-1 takes an arc shape; the side HM-2 comprises an outer side 2-21 positioned outside the cross section and an inner side 2-22 positioned inside the cross section, and the outer side 2-21 and the inner side 2-22 are arc-shaped; the lower portion HM2-3 is planar, stepped, and includes two lower planes, the first lower plane 2-31 being located in connection with the outer side portion 2-21 higher than the second lower plane 2-32 being connected with the inner side portion 2-22. The first lower plane 2-31 and the outer side 2-21 are smoothly transited through the cambered surface.

Referring to fig. 3 (a) and 3 (b), in the present embodiment, the cutter 1 for processing the sponge is made of a heat conductive material, preferably, the cutter 1 is made of an electrothermal resistance alloy, such as Cr20Ni80. Before machining the sponge, the tool 1 needs to be preheated to the machining temperature of the sponge. The cutter 1 is provided with an edge 11, and the edge 11 has a shape (content to be processed of a soft material) preset according to a desired cross section of the processed sponge. In addition, to facilitate the fixing of the tool 1, the tool 1 further comprises at least one tool mounting portion 12.

The blade 11 of the tool 1a of the present embodiment is in an open loop shape, and includes a first blade 11a at an upper portion, the first blade 11a being in an arc shape, a second blade 11b at a middle portion, the second blade 11b being in an arc shape, a third blade 11c at a lower portion, and the third blade 11c being in a planar shape. The first, second and third blade portions 11a, 11b, 11c smoothly transition.

Referring to fig. 3 (d), the blade 11 is open-loop, mainly to reduce the resistance during machining, namely: when the sponge is machined by using the tool 1a, only the outer portion 2-21, the portion of the upper portion HM2-1, and the first lower plane 2-31 of the cross section of the sponge HM2 may be machined. In addition, in order to ensure that the blade 11 can process the desired processing content of the sponge (soft material), the blade 11 preferably includes a processing area larger than the desired processing content, for example, the blade 11 may further include a spare blade 11d extending slightly above and outside the sponge upper portion HM2-1 along the front end of the upper first blade 11a, and the spare blade 11 may prevent that some of the desired processing content is not processed due to the track deviation of the processing of the cutter 1, and may also be used to remove burrs generated during the processing.

The blade 11 is set to be preset according to the desired cross section of the processed sponge, but it does not mean that the shape of the blade 11 is exactly the same as the desired cross section of the processed sponge. With continued reference to fig. 3 (d), in fact, as shown in this embodiment, the blade 11 may only match a partial cross-section of the sponge HM2 (e.g., the outer portion 2-21 of the cross-section of the sponge, a portion of the upper portion HM2-1, and the first lower plane 2-31). Namely: the desired processed sponge HM2 can be completed by processing together a plurality of cutters 1 having a shape preset according to the peripheral surface of the sponge HM 2.

Example 2

Referring to fig. 3 (c) and 3 (d), the inner portion 2-22 of the cross section of the sponge HM2 and the other portion of the upper portion HM2-1 can be processed by another cutter 1b which is formed by slightly changing the shape of the cutter 1 a. The blade 11-1 of the cutter 1b of the present embodiment is also in an open loop shape, and is preset in shape according to the inner side 2-22 of the cross section of the sponge and the other part of the upper portion HM 2-1. The blade includes an upper first blade 11-1a, the first blade 11a is arc-shaped, a middle second blade 11-1b, and the second blade 11-1b is arc-shaped and extends toward the lower portion of the blade 11-1. The first blade 11a and the second blade 11b smoothly transition with each other.

Referring to fig. 3 (a) -3 (c), in order to facilitate processing of the sponge body, and to prevent the sponge body from being difficult to process due to excessive resistance, the cutter 1 (1 a, 1 b) is in a sheet shape, and the thickness t thereof is set to about 0.8mm, such as 0.6mm to 0.9mm. Of course, the thickness of the tool 1 (1 a, 1 b) may also be suitably thickened or thinned depending on the level of precision of the soft material to be processed, but basically, it is required that the thickness of the tool 1 (1 a, 1 b) should be less than 1.5mm. Similarly, in order to reduce friction between the tool 1 (1 a, 1 b) and the sponge body and reduce resistance, the width w of the tool 1 (1 a, 1 b) is preferably about 2mm, for example, 0.5mm to 3mm. Similarly, the width W of the tool 1 (1 a, 1 b) can be widened appropriately according to the strength of the soft material to be processed, and breakage of the tool 1 due to excessive strength of the soft material can be prevented, but basically, the width of the tool 1 is required to be smaller than 5mm.

Further, in order to enhance sharpness of the tool 1 (1 a, 1 b), thereby further facilitating processing of the sponge by the tool 1 (1 a, 1 b), at least one end of the blade portion 11 (11-1) in the width direction is provided with a chamfer 13. Of course, the blade 11 (11-1) may be provided with chamfers 13 (13-1) at both ends in the width direction thereof, and the chamfers 13 provided at both sides may facilitate the reciprocating movement of the tool 1 when processing the sponge HM2, thereby removing burrs and the like on the peripheral surface of the sponge.

Further, in order to enhance sharpness of the cutter 1, the blade portion 11 may be further provided with chamfers 13 (13-1) on both sides in the thickness direction so that the end portion of the blade portion 11 has a triangular shape in cross section in the thickness direction.

With continued reference to fig. 3 (a), 3 (c), the tool mounting portion 12 may include two places, and the blade portion 11 may be disposed between the two places of the tool mounting portion 12. The two cutter mounting portions 12 are respectively clamped in the clamping of the cutter 1, so that the blade portion 11 can be prevented from being in a cantilever state.

Example 3

Referring to fig. 4 (a) and 4 (b), in the present embodiment, the blade 11-2 of the tool 1c is the same as the blade 11 of the tool 1 of embodiment 1, except that the tool 1c includes one tool mounting portion 12a. The tool mounting portion 12a may be provided on the outer side near the middle of the blade portion 11-2 so that the blade portion 11-2 is uniformly stressed in processing the sponge. Since the tool 1c may be biased during machining when there is only one tool mounting portion 12a, the tool mounting portion 12a may be further provided with a mounting through hole 12b for mounting a screw in order to solve the problem.

Further, the tool mounting portion 12 may further include three portions (not shown, but may be obtained by combining the tool mounting portions 12 of fig. 3 (a), 3 (c), and 4 (a)) located outside the upper portion, the lower portion, and the middle portion of the blade portion 11, and the tool 1 is clamped by clamping the three tool mounting portions 12, respectively, so that the blade portion 11 is further prevented from being in a cantilever state.

Example 4

Referring to fig. 5 (a) -5 (c), in the present embodiment, the processed sponge HM3 is substantially the same as the sponge HM2, except that the outer side portion 2-21a is further provided with a concave portion 2-21b, and the concave portion 2-21b has a V-shape.

The concave portions 2-21b can be formed by the cutter 1d having the following shape.

The blade 11-3 has a V-shape and includes a first blade 11-3a extending obliquely upward from the tip of the blade 11-3 toward the tool attachment 12c, and a second blade 11-3b extending obliquely downward from the tip of the blade 11 toward the tool attachment 12, the first and second blades 11-3a and 11-3b being connected at the tip of the blade 11-3. The first blade portion 11a and the second blade portion 11b are respectively connected to the tool mounting portion 12c, and a cavity 12d is formed in the tool 1d, which mainly serves to facilitate removal of the cut sponge when the tool 1 processes the concave portions 2 to 21b of the sponge.

Similarly, in order to enhance the sharpness of the cutter 1 and further facilitate the processing of the sponge by the cutter 1, at least one end of the first blade portion 11-3a and the second blade portion 11-3b in the plate thickness direction of the cutter 1 is provided with a chamfer 13. Of course, the blade 11 may be provided with chamfers 13-1d at both ends in the plate thickness direction, and the chamfers 13 may be provided at both sides so that the tool 1 can travel back and forth during processing of the sponge, thereby removing burrs and the like on the peripheral surface of the sponge.

The cutter can be obtained by adopting different processing methods (such as CNC, sheet metal stamping, wire cutting and other processing modes) according to the precision grade of the soft material to be processed, and has low processing cost and easy processing.

The cutter almost does not need maintenance, and the maintenance cost is low.

The cutter can be arranged on a common milling machine, and the sponge body is horizontally adhered to the table top of the milling machine through the gummed paper during processing, so that the processing of the sponge body can be completed. Alternatively, a mating tool machining device 2 may be provided specifically for clamping the tool, as will be described in more detail below with respect to the machining device 2.

The processing device 2 can be used for processing soft materials, and for convenience of explanation, a sponge as a soft material will be described below as an example.

As described above, the tool 1 may include one tool mounting portion 12 or two tool mounting portions 12 or a plurality of tool mounting portions 12, and in correspondence therewith, the tool holding portion 22 may also include one, two or more. In the present embodiment, the tool holding portion 22 and the tool mounting portion 12 each include two places.

The tool mounting portion 12 is formed in a sheet shape, and the tool holding portion 22 includes two portions, and the two portions of the tool holding portion 22 are provided with groove portions 221, respectively, and the tool mounting portion 12 is accommodated in the groove portions 221 and is screwed. Of course, in other embodiments (e.g., embodiment 3), the tool mounting portion 12 may further include a through hole 12b, and in correspondence therewith, the tool holding portion 22 may be provided with a screw hole that is cooperatively locked with the through hole 12b.

In the present embodiment, the cutter 1 is driven by the driving section 24 to travel to process the sponge HM1. A sponge holding portion (soft material holding portion) 23 for holding the soft material is provided in a region which can be covered when the driving portion 24 drives the cutter 1 to travel.

Since the sponge HM1 to be processed is annular, the driving section 24 follows a predetermined trajectory in accordance with the processing content of the sponge HM1, that is: can be driven in at least the X-axis direction and the Y-axis direction. The driving unit 24 may select one or more robots to directly drive the tool 1 to travel in the X/Y axis direction.

Of course, the tool 1 and the tool holding portion 22 may be fixed, and the driving portion 24 may directly drive the soft material holding portion 23 to travel in the X/Y axis direction according to a predetermined trajectory in accordance with the processing content of the sponge HM1.

Alternatively, the driving unit 24 may be realized by driving the cutter 1 to travel by using a single-axis robot in the X-axis direction and driving the soft material holding unit 23 to travel by using a single-axis robot in the Y-axis direction.

One function of the Z-axis driving portion 241b is to prevent the tool 1 from interfering with the sponge HM1 due to a debugging error when the tool 1 is positioned at the upper portion of the sponge HM1 to be processed in the initial state. Another function of the Z-axis driving part 241b is to facilitate accurate adjustment of the Z-axis direction position of the tool 1, which may result in an inaccurate matching of the tool 1 with the position to be processed of the sponge due to a processing error, an assembly error, etc., and thus, the Z-axis direction position of the tool 1 may be accurately adjusted by adjusting the extension stroke of the first cylinder 241 b.

A sponge holding portion (soft material holding portion) 23 is provided at a lower portion of the processing device 2. In this embodiment, the sponge holding portion 23 is matched with the lower portion of the annular sponge HM1 (HM 2), and includes a holding surface 231 for holding the sponge HM1 (HM 2), and in this embodiment, when the sponge HM1 is fed, the lower portion may be attached with adhesive paper, and when the sponge HM1 is placed on the sponge holding portion 23, the sponge is directly adhered to the holding surface 231 via the adhesive paper, thereby holding the sponge. Of course, adhesive paper or other adhesive material may be adhered to the holding surface 231 in the same manner, so that the sponge HM1 is held by adhesion.

Since the sponge HM1 is annular in this embodiment, it is necessary to change the angle of the tool 1 at the time of machining the transition surface, thereby realizing smooth machining of the sponge HM1. In the present embodiment, an angle changing portion 242 for changing the angle of the cutter 1 is provided. The angle conversion portion 242 is provided on the driving portion 24, specifically, on the output end of the first cylinder 241b (Z-axis driving portion).

The output end of the angle conversion unit 242 is connected to the tool holding unit 22 to drive the tool 1 to change the angle. In the present embodiment, the angle conversion portion includes the first motor 242a, and an output shaft of the first motor 242a is connected to the tool holding portion 22, and the tool 1 is rotatable about the axial center of the output shaft.

The angle conversion unit 242 further includes a control unit 242b, and the control unit 242b controls the output of the first motor 242a to change the angle of the tool 1 according to the processing of the soft material. The control part 242b may be an encoder provided on the first motor 242a, and corrects the output of the first motor 242a through closed loop control, thereby accurately determining the angle of the tool 1. Of course, the control part may also include an angle sensor, a CCD detection, etc., to correct the output of the first motor 242a by monitoring the shape of the sponge in real time.

In order to further precisely adjust the position of the tool 1, an adjusting portion 244 is further provided on the Z-axis driving portion 241b, and the tool holding portion 22 is provided on the adjusting portion 244.
