Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy forging processing technology, and more specifically, it relates to an aluminum alloy forging fixed-length cutting and positioning component. Background Technology

[0002] Aluminum alloy forgings are parts obtained by plastically deforming aluminum alloy materials through forging processes. The manufacturing process utilizes external force to induce plastic flow in the metal billet, thereby obtaining the desired shape and properties. Aluminum alloy forgings have advantages such as high strength, corrosion resistance, light weight, and good thermal conductivity, and occupy an important position in the industrial field. Ring-cylindrical aluminum alloy forgings are a common type of aluminum alloy forging. Ring-cylindrical aluminum alloy forgings usually need to be cut to a fixed length. By precisely controlling the cutting length, waste of scrap material is reduced and material utilization is improved.

[0003] When cutting existing ring-shaped aluminum alloy forgings to a fixed length, the distance from the end face of the aluminum alloy forging to the saw blade must be manually measured each time, and the position of the aluminum alloy forging needs to be frequently adjusted to ensure that the length of the cut aluminum alloy forging meets the requirements, resulting in very low cutting efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the defects in the existing technology and provide an aluminum alloy forging length cutting and positioning component that facilitates rapid positioning of aluminum alloy forgings.

[0005] To achieve the above objectives, the present invention provides a fixed-length cutting and positioning assembly for aluminum alloy forgings, comprising: a cutting table, on which a positioning unit and a clamping unit are mounted, the cutting table having a cutting groove, the positioning unit and the clamping unit being arranged opposite each other along the length direction of the cutting groove, the positioning unit including an abutment portion, and a reference surface being formed at one end of the abutment portion near the cutting groove.

[0006] By using the aluminum alloy forging length cutting and positioning component described in this utility model, when adjusting the position of the aluminum alloy forging, the end face of the aluminum alloy forging is made to fit with the reference surface of the abutment part, thus quickly completing the positioning of the aluminum alloy forging and greatly improving the cutting efficiency of the aluminum alloy forging.

[0007] Preferably, the positioning unit further includes an L-shaped mounting plate, which is detachably mounted on the cutting table, and the abutment portion is mounted on the mounting plate. This design facilitates the maintenance or replacement of the positioning unit.

[0008] Preferably, the abutment portion is provided in three sets, arranged in a triangle. The end face of each abutment portion near the cutting groove is a spherical convex surface, and the vertex of the spherical convex surface forms point contact with the end face of the aluminum alloy forging. The plane defined by the vertices of the three spherical convex surfaces is the reference plane. This design can reduce the requirements for the production precision of the abutment portion, which is beneficial to reducing production costs.

[0009] Preferably, the mounting plate has three through slots that mate with the three sets of abutment portions. Each set of abutment portions includes a bolt, a first nut, and a second nut. The bolt passes through the through slot, and both the first nut and the second nut are threaded onto the bolt. The first nut and the second nut are respectively fastened to the two side surfaces of the mounting plate, and the spherical convex surface is the end face of the bolt near the cutting groove. This design allows adjustment of the distance between the reference surface and the saw blade by adjusting the bolt, the first nut, and the second nut, adapting to different length requirements for slitting.

[0010] Preferably, all three through slots are elongated, comprising a first through slot, a second through slot, and a third through slot. The first through slot is located at the bottom of the mounting plate and extends horizontally. The second and third through slots are symmetrically arranged about the mounting plate, with both located above the first through slot and inclined upwards along a direction away from the plane of symmetry of the mounting plate. This design allows the bolts to be moved and adjusted along the length of the through slots, thus accommodating annular aluminum alloy forgings with different radial dimensions.

[0011] Preferably, the extensions of the second and third through slots intersect at the midpoint of the first through slot, the included angle between the second and third through slots is 60°, and the three bolts are arranged in an equilateral triangle. This design avoids stress concentration, prevents the mounting plate from bending or being damaged, and improves the durability of the mounting plate.

[0012] Preferably, the mounting plate has reinforcing ribs at its corners. This design increases the rigidity of the mounting plate, which in turn improves its durability.

[0013] Preferably, the clamping unit includes two telescopic drive members symmetrically distributed about the mounting plate. The telescopic drive members are fixedly mounted on the cutting table, and clamping plates are fixedly connected to the telescopic ends of the two telescopic drive members that are close to each other. This design facilitates adjusting the end face of the aluminum alloy forging to fit against the reference surface and helps ensure the stability and accuracy of the aluminum alloy forging cutting.

[0014] The beneficial effects of this utility model are as follows:

[0015] By using the aluminum alloy forging length cutting and positioning component described in this utility model, when adjusting the position of the aluminum alloy forging, the end face of the aluminum alloy forging is made to fit with the reference surface of the abutment part, thus quickly completing the positioning of the aluminum alloy forging and greatly improving the cutting efficiency of the aluminum alloy forging.

[0027] The subject matter described herein will now be discussed with reference to exemplary embodiments. It should be understood that these embodiments are discussed to enable those skilled in the art to better understand and implement the subject matter described herein. Changes may be made to the function and arrangement of the elements discussed without departing from the scope of this specification. Various processes or components may be omitted, substituted, or added as needed in the examples. Furthermore, features described in some examples may be combined in other examples.

[0028] To better understand this utility model, the following is in conjunction with... Figures 1-6 This invention provides a detailed description of a fixed-length cutting and positioning component for aluminum alloy forgings.

[0029] Example 1:

[0030] like Figures 1-3 As shown, an aluminum alloy forging fixed-length cutting and positioning assembly includes: a cutting table 100, on which a positioning unit 200 and a clamping unit 300 are mounted, the cutting table 100 is provided with a cutting groove 110, the positioning unit 200 and the clamping unit 300 are arranged opposite to each other along the length direction of the cutting groove 110, the positioning unit 200 includes an abutment portion 210, and a reference surface is formed at one end of the abutment portion 210 near the cutting groove 110.

[0031] It should be noted that the cutting table 100 is used to provide support for the annular aluminum alloy forging 500. The cutting table 100 is also equipped with a cutting device 400. The cutting device 400 cuts the aluminum alloy forging 500 through a saw blade 410. The cutting device 400 is existing technology equipment, and its specific structure will not be described in detail here.

[0032] The positioning unit 200 and the clamping unit 300 are arranged on both sides of the longitudinal extension plane of the cutting groove 110. The distance between the reference surface and the saw blade 410 is the preset cutting length of the aluminum alloy forging 500. Before cutting, the aluminum alloy forging 500 can be lifted by the lifting tool to adjust the position of the aluminum alloy forging 500 so that the end face of the aluminum alloy forging 500 is in contact with the reference surface, thereby ensuring that the length of the aluminum alloy forging 500 after cutting meets the requirements.

[0033] The clamping unit 300 clamps and positions the aluminum alloy forging 500 after positioning, which can prevent the aluminum alloy forging 500 from rolling on the cutting table 100 during the cutting process and affecting the cutting accuracy.

[0034] In this embodiment, the saw blade 410 is arranged in the vertical direction along its length, and the saw blade 410 of the cutting device 400 moves along the length direction of the cutting groove 110 to cut the aluminum alloy forging 500.

[0035] By using the aluminum alloy forging length cutting and positioning component of this utility model, when adjusting the position of the aluminum alloy forging 500, the end face of the aluminum alloy forging 500 is made to fit with the reference surface of the abutment part 210, and the positioning of the aluminum alloy forging 500 can be completed quickly, which greatly improves the cutting efficiency of the aluminum alloy forging 500.

[0036] Example 2:

[0037] As an optimization of Example 1, such as Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, the positioning unit 200 also includes an L-shaped mounting plate 220, which is detachably mounted on the cutting table 100, and the abutment part 210 is mounted on the mounting plate 220.

[0038] It should be noted that the L-shaped mounting plate 220 includes a vertical plate and a horizontal plate, and the included angle between the vertical plate and the horizontal plate is 90°.

[0039] In this embodiment, the mounting plate 220 is detachably mounted on the cutting table 100 by screws, thereby ensuring the stability of the mounting plate 220. The mounting plate 220 can be removed by unscrewing the screws, which facilitates the maintenance or replacement of the positioning unit 200.

[0040] Example 3:

[0041] As an optimization of Example 2, such as Figure 1 , Figure 3 and Figure 4 As shown, the abutment part 210 is provided in three sets, and the three sets of abutment parts 210 are distributed in a triangle. The end face of the abutment part 210 near the cutting groove 110 is a spherical convex surface 2111. The vertex of the spherical convex surface 2111 forms a point contact with the end face of the aluminum alloy forging 500. The plane determined by the vertices of the three spherical convex surfaces 2111 is the reference plane.

[0042] It should be noted that the vertex of the spherical convex surface 2111 refers to the point on the spherical convex surface 2111 that is closest to the vertical distance from the surface of the saw blade 410 after the abutment part 210 is installed. When adjusting and positioning the aluminum alloy forging 500, the end face of the aluminum alloy forging 500 abuts against the three sets of abutment parts 210. At this time, the end face of the aluminum alloy forging 500 contacts the vertices of the three spherical convex surfaces 2111, and the end face of the aluminum alloy forging 500 fits against the reference surface. Through this design, the production accuracy requirements of the abutment part 210 can be reduced, which is conducive to reducing production costs.

[0043] If the end face of the abutment part 210 near the cutting groove 110 is a plane, this plane is the reference plane. During the production process, this plane must be large enough and the flatness of the plane must be high. In addition, the installation accuracy of the abutment part 210 must also be high to ensure that the end face of the aluminum alloy forging 500 can be completely fitted with the reference plane. The production cost of the abutment part 210 is high.

[0044] Example 4:

[0045] As an optimization of Example 3, such as Figures 3-6 As shown, the mounting plate 220 is provided with three through slots 221 that are respectively installed in conjunction with the three sets of abutment parts 210. Each set of abutment parts 210 includes a bolt 211, a first nut 212 and a second nut 213. The bolt 211 passes through the through slot 221. The first nut 212 and the second nut 213 are threaded to the bolt 211. The first nut 212 and the second nut 213 are respectively fastened to the two side surfaces of the mounting plate 220. The spherical convex surface 2111 is the end face of the bolt 211 near the cutting groove 110.

[0046] It should be noted that the first nut 212 is located on the side of the mounting plate 220 near the cutting groove 110, and the second nut 213 is located on the side of the mounting plate 220 away from the cutting groove 110. During initial use, the distance between the end face of the aluminum alloy forging 500 and the saw blade 410 needs to be measured manually, and the position of the aluminum alloy forging 500 needs to be adjusted so that the distance between the end face of the aluminum alloy forging 500 and the saw blade 410 is the preset length (the fixed length required for the aluminum alloy forging 500 to be cut). Then, the clamping unit 300 is controlled to clamp the aluminum alloy forging 500, and then the mounting plate 220 is fixed on the cutting table 100 with screws.

[0047] Next, the threaded section of one of the bolts 211, which is threaded with the first nut 212, is inserted into the through groove 221, so that the first nut 212 fits against the surface of the mounting plate 220 near the cutting groove 110. The bolt 211 is rotated until the spherical convex surface 2111 of the bolt 211 abuts against the end face of the aluminum alloy forging 500. Then, the second nut 213 is screwed into the threaded section of the bolt 211 until the second nut 213 abuts against the surface of the mounting plate 220 away from the cutting groove 110. The relative position of the mounting plate 220 and the bolt 211 is fixed by the locking force. The above steps are repeated to complete the installation of the three sets of abutment parts 210, ensuring that the reference surface fits against the end face of the aluminum alloy forging 500 and ensuring the installation accuracy of the three sets of abutment parts 210.

[0048] By adjusting bolt 211, first nut 212 and second nut 213, the distance between the reference surface and the saw blade 410 can be adjusted, which can adapt to different length requirements for cutting. When one of the components of the abutment part 210 is damaged, only the corresponding component needs to be replaced, which helps to reduce the maintenance cost of the abutment part 210.

[0049] Example 5:

[0050] As an optimization of Example 4, such as Figure 4 and Figure 6 As shown, all three through slots 221 are elongated. The three through slots 221 include a first through slot 2211, a second through slot 2212, and a third through slot 2213. The first through slot 2211 is located at the bottom of the mounting plate 220 and extends horizontally. The second through slot 2212 and the third through slot 2213 are symmetrically arranged about the mounting plate 220. The second through slot 2212 and the third through slot 2213 are both located above the first through slot 2211 and are inclined upwards along the direction away from the symmetrical plane of the mounting plate 220.

[0051] It should be noted that the bolt 211 can be moved and adjusted along the length of the through groove 221 and fixed by the first nut 212 and the second nut 213, thereby adapting to annular aluminum alloy forgings 500 with different radial dimensions. It can position annular aluminum alloy forgings 500 with different radial dimensions, improving the applicability of the aluminum alloy forging fixed length cutting and positioning assembly. The symmetry plane of the mounting plate 220 is a vertical plane, and the length direction of the first through groove 2211 is perpendicular to the symmetry plane of the mounting plate 220. The first through groove 2211, the second through groove 2212 and the third through groove 2213 are all set on the vertical plate of the mounting plate 220.

[0052] Example 6:

[0053] As an optimization of Example 5, such as Figure 4 and Figure 6 As shown, the extensions of the second through groove 2212 and the third through groove 2213 intersect at the midpoint of the first through groove 2211. The included angle between the second through groove 2212 and the third through groove 2213 is 60°. The three bolts 211 are distributed in an equilateral triangle.

[0054] It should be noted that when the three sets of abutment parts 210 are installed, the bolts 211 passing through the first through groove 2211 are located at the midpoint of the first through groove 2211, and the bolts 211 passing through the second through groove 2212 and the third through groove 2213 are symmetrically distributed about the mounting plate 220. This makes the three bolts 211 located at the three vertices of the same equilateral triangle. With this design, when the position of the aluminum alloy forging 500 is adjusted so that the end face of the aluminum alloy forging 500 abuts against the three bolts 211, the force exerted by the aluminum alloy forging 500 on the bolts 211 is transferred to the mounting plate 220, and the force distribution is more uniform. This can avoid stress concentration, and the mounting plate 220 is less likely to bend or be damaged, which helps to improve the durability of the mounting plate 220.

[0055] Example 7:

[0056] As an optimization of Example 6, such as Figure 6 As shown, a reinforcing rib 222 is provided at the corner of the mounting plate 220.

[0057] It should be noted that by setting triangular reinforcing ribs 222 at the corners of the L-shaped mounting plate 220, the rigidity of the mounting plate 220 can be improved, ensuring that the vertical plate of the mounting plate 220 is not easily bent, thereby further improving the durability of the mounting plate 220.

[0058] Example 8:

[0059] As an optimization of Example 7, such as Figure 1 As shown, the clamping unit 300 includes two telescopic drive members 310 that are symmetrically distributed about the mounting plate 220. The telescopic drive members 310 are fixedly mounted on the cutting table 100, and the telescopic ends of the two telescopic drive members 310 that are close to each other are fixedly connected to the clamping plate 320.

[0060] It should be noted that before adjusting the position of the aluminum alloy forging 500, the two telescopic drive components 310 drive the two clamping plates 320 to move, so that the distance between the end faces of the two clamping plates 320 approaching each other is slightly larger than the radial dimension of the annular aluminum alloy forging 500. During the adjustment of the position of the aluminum alloy forging 500, the two clamping plates 320 can play a certain guiding role, so that the length direction of the aluminum alloy forging 500 is perpendicular to the reference plane. That is to say, the end face of the aluminum alloy forging 500 is parallel to the reference plane, which is conducive to adjusting the end face of the aluminum alloy forging 500 to fit with the reference plane. After the position of the aluminum alloy forging 500 is adjusted, the two telescopic drive components 310 drive the two clamping plates 320 to move towards each other, thereby clamping the aluminum alloy forging 500 and ensuring the stability and accuracy of the cutting of the aluminum alloy forging 500.

[0061] In this embodiment, the telescopic drive 310 is configured as a dual-rod servo electric cylinder, thereby driving the clamping plate 320 to stably clamp the aluminum alloy forging 500.

[0062] The embodiments of the utility model have been described above with reference to the accompanying drawings. However, the embodiments are not limited to the specific implementation methods described above. The specific implementation methods described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of the embodiments without departing from the spirit of the embodiments and the scope of protection of the claims, and all of these forms are within the protection scope of the embodiments.
