Abstract
Description
Technical Field
[0001] The utility model relates to the field of casting, in particular to a riser cutting tool and a riser cutting device comprising the same. Background Art
[0002] During the casting process, risers are used to eliminate internal shrinkage defects. They compensate for shrinkage during the casting's transition from liquid to solid phase, compensating for shrinkage caused by solidification. Risers are typically located in thicker areas of the casting. For differential shell parts, they are located at the top of the casting.
[0003] However, the riser remaining on the top of the casting affects the normal use of the part, so the riser on the top of the part needs to be removed. However, when operators remove the riser manually, there will often be residual riser on the top of the part, and consistency is difficult to ensure. Utility Model Content
[0004] The utility model aims to provide a riser cutting tool, which can effectively limit the position of parts, ensure the reliability of the riser cutting position and the consistency of the state of the parts after cutting.
[0005] In order to achieve the above-mentioned object, the present invention provides a riser cutting tool, which includes a second supporting surface of a tool body, a first limit block second supporting surface, a second limit block second supporting surface, and a supporting second supporting surface arranged between the first limit block second supporting surface and the second limit block second supporting surface, wherein the first limit block second supporting surface and the second limit are respectively located at two ends of the part second supporting surface, and the supporting second supporting surface is located below the part second supporting surface to support the part second supporting surface;
[0006] The second supporting surface of the tool body is provided with a second supporting surface with a positioning hole for positioning the riser cutting tool.
[0007] Preferably, the supporting second supporting surface is provided with a first supporting surface and a second supporting surface, and the first supporting surface and the second supporting surface are in contact with the outer surface of the second supporting surface of the part.
[0008] Preferably, the surface of the second supporting surface of the second limit block facing the second supporting surface of the first limit block abuts against the bottom of the second supporting surface of the part.
[0009] Preferably, a second supporting surface is provided on the second supporting surface of the first limit block, and the second supporting surface is in contact with the outer surface of the second supporting surface of the part.
[0010] Preferably, a step is provided on the top of the second supporting surface of the part, and the second supporting surface of the first limit block cooperates with the step and together with the second supporting surface of the second limit block to limit the second supporting surface of the part.
[0011] Preferably, a second groove capable of accommodating iron filings is provided at the bottom of the second supporting surface.
[0012] Preferably, a first groove and a second supporting surface capable of accommodating iron filings are provided at the bottom of the first supporting surface and the second supporting surface.
[0013] Preferably, the upper end surface of the second supporting surface of the first limit stop is connected to the second supporting surface through an arc filter.
[0014] Preferably, the second supporting surface is connected to the first supporting surface and the second supporting surface through an arc transition.
[0015] The utility model also provides a riser cutting device, which includes a cutting tool and the riser cutting tool. The riser cutting tool is connected to the working surface of the cutting tool through the second supporting surface of the positioning hole. The connection position between the second supporting surface of the riser and the top of the second supporting surface of the part is located directly below the cutting blade.
[0016] According to the above technical solution, the present invention can place the part to be processed between the first and second limit stops. The first and second limit stops can restrict the position of the part, so that the part has only the degree of freedom of rotation.

Therefore, a support is provided to support the part, thereby achieving the function of the riser cutting tool to limit the position of the part.
[0017] The fixture is secured to the cutting tool's working surface via the positioning holes, with the cutting blade aligned with the boundary between the part and the heat-generating riser. This ensures that the riser is reliably removed from the top of the part as the blade descends. Because the riser cutting fixture can control the position of the part, each part secured with the fixture maintains a consistent finish after riser cutting.

[0033] The following is a detailed description of the specific embodiments of the present invention in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention and are not intended to limit the present invention.
[0034] In the present utility model, unless otherwise stated, the directional words contained in the terms "two ends, below, outer surface, bottom, upper end face" only represent the orientation of the term in normal use, or are common names understood by those skilled in the art, and should not be regarded as limitations on the term.
[0035] See also Figure 1-6 The riser cutting tool comprises a tool body 1, a first limit stop 2, a second limit stop 3 and a support 4 provided between the first limit stop 2 and the second limit stop 3, wherein the first limit stop 2 and the second limit stop are respectively located at both ends of the part 10, and the support 4 is located below the part 10 to support the part 10;
[0036] The tool body 1 is provided with a positioning hole 11 for positioning the riser cutting tool.
[0037] Through the implementation of the above technical solution, part 10 is placed between first limit stop 2 and second limit stop 3. First limit stop 2 and second limit stop 3 can restrict the position of part 10, so that part 10 has only rotational freedom. Because part 10 is cylindrical, it will roll if placed on a flat surface, resulting in unstable position of part 10. Therefore, support 4 is provided to support part 10, thereby achieving the position restriction function of part 10 by the riser cutting tool.
[0038] The tool body 1 is fixed to the working surface of the cutting tool through the positioning hole 11, and the cutting blade is aligned with the boundary between the part 10 and the heat riser. This ensures that the riser can be reliably cut from the top of the part 10 during the descending process of the cutting blade. Because the riser cutting tool can limit the position of the part 10, each part 10 fixed by the riser cutting tool can maintain a good consistency after the riser cutting work is completed.
[0039] In this embodiment, preferably, the support 4 is provided with a first support surface 41 , and the first support surface 41 is in contact with the outer surface of the part 10 .
[0040] In order to better support the part 10, a first supporting surface 41 is provided on the support 4. The first supporting surface 41 is set to an arc shape with the same curvature as the outer surface of the part 10, and supports the part 10 by fitting with the outer surface of the part 10.
[0041] In one embodiment, the first supporting surface 41 is a continuous surface, and the support function for the part 10 is achieved by cooperating with the outer surface of the part 10 .
[0042] In another embodiment, the first support surface 41 is set as a discontinuous surface, or is set as multiple support points that can fit with the outer surface of the part 10, and the support effect on the part 10 is achieved by the cooperation between the multiple support points and the outer surface of the part 10.
[0043] Of course, the first support surface 41 can also be configured as multiple continuous surfaces, or a combination of continuous surfaces and support points to support the part 10. Regardless of whether the continuous surface, support points, or a combination of continuous surfaces and support points are used to support the part 10, these support surfaces that are in contact with the outer surface of the zero point 10 are all located on a curved surface with the same curvature as the outer surface of the part 10.
[0044] In this embodiment, preferably, the surface of the second limit stop 3 facing the first limit stop 2 abuts against the bottom of the component 10 .
[0045] The bottom of the part 10 is pressed against the second limit stop 3 so that the position of the part 10 can be limited by the second limit stop 3, thereby determining the relative position of the part 10 in the riser cutting tool. Moreover, when the cutting blade starts to cut the riser, limiting the bottom of the part 10 by the second limit stop 3 can prevent the part 10 from moving during the cutting process, thereby effectively ensuring the accuracy of the cutting position and the consistency of the state of the part after cutting.
[0046] In this embodiment, preferably, a second supporting surface 21 is provided on the first limit stop 2 , and the second supporting surface 21 is in contact with the outer surface of the part 10 .
[0047] The cutting blade cuts the riser on the outside of the first limit stop 2, and a lot of iron chips are generated during the cutting process. These iron chips move at high speed and fly everywhere, and may fly to the position of the support 4. If iron chips fly onto the first support surface 41, since these iron chips on the first support surface 41 can move freely on the surface of the first support surface 41, they will affect the stability of the part 10 during the cutting process, thereby affecting the surface quality of the cut surface. Moreover, these iron chips will gradually slide to the bottom of the first support surface 41 as they vibrate, and these iron chips will raise the position of the part 10 at the bottom of the first support surface 41, causing the position of the part 10 to tilt, etc., affecting the cut surface after cutting.
[0048] Therefore, the second supporting surface 21 is arranged to fit the outer surface of the part 10 , which can not only support the part 10 but also block the iron chips generated during the cutting process to prevent the iron chips from affecting the first supporting surface 41 .
[0049] In this embodiment, preferably, a step is provided on the top of the part 10 , and the first limit stop 2 cooperates with the step and together with the second limit stop 3 to limit the part 10 .
[0050] The first limit stop 2 cooperates with the step on the part, so that the part 10 cannot continue to move toward the first limit stop 2, and on the other side, the bottom of the part 10 abuts against the second limit stop 3, so that the part 10 cannot continue to move toward the second limit stop 3. As a result, the position of the part 10 is limited between the second limit stop 3 and the first limit stop 2. Therefore, the riser cutting tool realizes reliable limitation of the part 10, thereby reliably ensuring the relative position state of the part 10 and the riser cutting tool.
[0051] In this embodiment, preferably, a second groove 22 capable of accommodating iron filings is provided at the bottom of the second supporting surface 21 .
[0052] Since iron chips flying during the cutting process are inevitable and there is inevitably a gap between the second supporting surface 21 and the part, the operator needs to clean the surface of the second supporting surface 21 after each cutting to prevent these iron chips from affecting the position state of the next part 10.
[0053] The second groove 22 is provided at the bottom of the second supporting surface 21 to collect the iron chips that are overcut during cutting. The iron chips in the cutting process slide along the surface of the second supporting surface 21 under the action of gravity until they fall into the second groove 22. On the one hand, the second groove 22 can accommodate the iron chips. On the other hand, since the second groove 22 has a certain volume, it can also store the iron chips, so that the operator does not have to clean the iron chips frequently, but can wait until the amount of iron chips in the second groove 22 reaches a certain level before cleaning the iron chips.
[0054] In this embodiment, preferably, a first groove 42 capable of accommodating iron filings is provided at the bottom of the first supporting surface 41 .
[0055] The purpose of providing the first groove 42 is the same as that of providing the second groove 22 , which is to store iron chips generated during the cutting process.
[0056] In this embodiment, preferably, the upper end surface of the first limit stop 2 and the second support surface 21 are connected via an arc filter.
[0057] The arc filtering connection between the upper end surface of the first limit stop 2 and the second support surface 21 can more conveniently place the part 10 . The filtering section of the arc can play a guiding role, guiding the part 10 to the second support surface 21 .
[0058] In this embodiment, preferably, the support 4 and the first support surface 41 are connected via an arc transition.
[0059] Providing an arc filtering connection between the upper end surface of the first limit stop 2 and the first supporting surface 41 can make it more convenient to place the part 10. The filtering section of the arc can play a guiding role, guiding the part 10 to the first supporting surface 41.
[0060] A riser cutting device includes a cutting tool and a riser cutting tool. The riser cutting tool is connected to the working surface of the cutting tool through a positioning hole 11. The connection position between the riser 101 and the top of the part 10 is located directly below the cutting blade.
[0061] The tool body 1 is fixed to the working surface of the cutting tool through the positioning hole 11, and the lowering position of the cutting blade is aligned with the boundary between the part 10 and the heat riser, so that the riser can be reliably cut off from the top of the part 10 during the lowering process of the cutting blade. Because the riser cutting tool can limit the position of the part 10, the part 10 fixed by the riser cutting tool can maintain the consistency of the cut state after the riser cutting work is completed.
[0062] The preferred embodiments of the present invention are described in detail above in conjunction with the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the scope of protection of the present invention.
[0063] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any appropriate manner without contradiction. In order to avoid unnecessary repetition, the present invention will not further describe various possible combinations.
[0064] In addition, the various embodiments of the present invention may be arbitrarily combined, and as long as they do not violate the concept of the present invention, they should also be regarded as the contents disclosed by the present invention.
