Description

Technical Field

[0001] The invention relates to the technical field of round ingot processing, and in particular to an adjustable round ingot base and a use method thereof. Background Art

[0002] Electron beam cold hearth melting furnaces are now widely used in metal smelting. With the development of technology, the size of the round ingots after smelting is getting larger and larger. For example, for round ingots with a diameter of φ850mm and a length of 500mm-1000mm, how to fix the large-size round ingots during the processing after smelting becomes a problem.

[0003] The existing fixture scheme uses V-shaped support blocks to position and fix cylindrical workpieces. One is a special type, where the distance between the left and right support blocks of the V-shaped block is fixed, and the size of the fixed cylinder is also fixed. The other is that the left and right support blocks are connected to the screw through internal threads, and the internal and external threads of the left and right support blocks have opposite spiral directions. The screw is driven by external force to drive the movement of the two support blocks and change the distance between the two support blocks to meet the support of different cylindrical workpieces. However, both of these have the following disadvantages:

[0004] 1. The cylindrical workpiece to be positioned needs to be a relatively regular circle, and the weight of the cylindrical workpiece cannot be too heavy. However, there are still problems in clamping and fixing round ingots with irregular cross-sections. Especially for round ingots weighing 500-1000kg, although the requirements can be met, the overall space occupied by the fixture is relatively large and the fixture is also relatively bulky;

[0005] 2. It is unable to meet the requirements of clamping and fixing round ingots of different lengths.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present invention and does not constitute any limitation to the present invention. Summary of the invention

[0007] In view of the shortcomings of the prior art mentioned above, the present invention provides an adjustable ingot base support and a method for using the same, in which the ingot is supported by a fixed block and an adjustable block installed on a fixing plate of the base support, so that the base support is detachable, and the spacing between the blocks is adjustable. The blocks can be flexibly adjusted for ingots of different lengths, and the adjustable blocks can be adjusted in their positions individually according to the contour of the ingot, so as to solve the problems of bulky base support clamps and unstable clamping of ingots with irregular contours.

[0010] In one embodiment of the present invention, each set of adjustable blocks can be moved along the second direction so as to adjust the interval between each set of adjustable blocks.

[0011] In one embodiment of the present invention, the adjustable mold block includes a mold block body, a supporting mechanism and a driving mechanism, the supporting mechanism includes a lower bracket installed above a fixed plate and an upper bracket installed below the mold block body, as well as a first supporting block installed below the upper bracket and a second supporting block installed above the lower bracket, and the first supporting block and the second supporting block are slidably connected along a second direction; the driving mechanism is installed on the second supporting block and is transmission-connected to the mold block body; so as to drive the relative sliding between the first supporting block and the second supporting block.

[0012] In one embodiment of the present invention, a limit block is further installed on one end of the second support block away from the driving mechanism. The limit block allows the first support block to pass through it and is used to limit the stroke of the first support block.

[0013] In one embodiment of the present invention, the driving mechanism includes a bearing seat, a fixed support and a screw, the bearing seat is mounted on the second support block; the fixed support is mounted on the block body; the screw is mounted on the bearing seat, and a driving member is installed at one end away from the block body, and is transmission-connected to the fixed support on the side close to the block body.

[0014] In one embodiment of the present invention, the adjustable block further comprises a protective cover, which is mounted on the bearing seat and the fixed support and covers the lead screw.

[0015] In one embodiment of the present invention, the angle between the fixed block and the adjustable block and the horizontal plane of the fixed plate is less than 45°.

[0016] In one embodiment of the present invention, pads are installed on the surfaces of the fixed block and the adjustable block.

[0017] The present invention also provides a method for using an adjustable round ingot support, comprising:

[0018] Positioning step: the round ingot is placed on the bottom bracket by the lifting device and is in contact with the fixed block of the bottom bracket only. At this time, the adjustable block of the bottom bracket is in the initial position and does not contact the round ingot;

[0019] Fixing step: by operating the driving member of the adjustable mold block, the supporting block of the adjustable mold block is driven to move close to the ingot to fine-tune the position of the ingot, and after the adjustable mold block contacts the ingot, the driving member is stopped and self-locked to complete the fixation of the ingot.

[0030] See also Figure 1 The present invention provides an adjustable ingot base, including a fixed plate 1, a fixed mold block 2 and an adjustable mold block 3. The fixed plate 1 includes a first direction and a second direction perpendicular to each other on its horizontal plane. The fixed mold block 2 is arranged at both ends of the fixed plate 1 along the first direction, and the adjustable mold block 3 is movably arranged between the fixed mold blocks 2 along the first direction.

[0031] Specifically, with the development of production technology, the size of the ingot 100 after smelting becomes larger and larger, and the contour formed after molding is generally an irregular circle. Therefore, directly placing it on the corresponding base and fixing it will cause the problem of unreliable and unstable contact support. In addition, the size of the ingot 100 under different processing parameters also requires a base of corresponding size to meet the support requirements for different ingot 100 workpieces.

[0032] In an embodiment of the present invention, a plurality of groups of mounting holes 10 can be provided on the fixed plate 1, and each group of mounting holes 10 is symmetrically distributed on both sides of the fixed plate 1; and at least two groups of fixed blocks 2 and two groups of adjustable blocks 3 are respectively installed on each group of mounting holes 10 on both sides of the fixed plate 1, each group of adjustable blocks 3 and each group of fixed blocks 2 include a pair of symmetrically arranged adjustable blocks 3 and a pair of fixed blocks 2, and the pair of adjustable blocks 3 and the pair of fixed blocks 2 are tilted to form a V-shaped structure. The first direction and the second direction perpendicular to each other on the fixed plate 1 correspond to the axial and radial directions of the ingot 100. In this way, each group of mounting holes 10 and each group of blocks are arranged axially along the ingot 100 in the first direction, and a pair of mounting holes 10 and a pair of blocks are arranged radially along the ingot 100 in the second direction. It should be noted that in the embodiment, the radial direction of the ingot 100 specifically refers to the radial direction parallel to the horizontal plane, so as to correspond to the second direction of the fixed plate 1 in the base. Please refer to the attached Figure 1 As shown, by installing the fixing plate 1 on the machine tool worktable 101 and making its first direction and second direction correspond to the X-axis and Y-axis of the machine tool processing horizontal plane, the ingot 100 with irregular circular contour can be subsequently processed.

[0033] It should be noted that, in the embodiment of the present invention, for the description of the fixed block 2 and the adjustable block 3, each group or one group represents the fixed block 2 and the adjustable block 3 in the first direction, and each pair or one pair represents the fixed block 2 and the adjustable block 3 in the second direction.

[0034] For more details, please see the attached Figure 1 The adjustable round ingot base includes a fixed plate 1, on which two groups of fixed blocks 2 are fixed by bolts, two groups of adjustable blocks 3 and two groups of fixed blocks 2 are located on the front and rear sides of the base (that is, the fixed plate 1), and the adjustable block 3 is located in the middle of the base. The fixed plate 1 is provided with multiple groups of mounting holes 10, and the spacing between the fixed blocks 2 and the adjustable blocks 3 can be flexibly adjusted according to round ingots 100 of different lengths to meet the placement and processing of round ingots 100 of various lengths.

[0035] In the embodiment of the present invention, the fixed mold block 2 and the adjustable mold block 3 arranged on the bottom bracket fixing plate 1 are used as the support of the round ingot 100. When in use, the distance between the fixed mold block 2 and the adjustable mold block 3 installed on the corresponding bottom bracket is first determined according to the parameter size of the round ingot 100, and the mounting holes 10 with corresponding size distances on the fixing plate 1 are selected to install each group of mold blocks (the mold blocks include the fixed mold blocks 2 and the adjustable mold blocks 3, the same below), so that the distance between each group of mold blocks and between a pair of mold blocks respectively corresponds to the length dimension and diameter dimension of the round ingot 100, and after the round ingot 100 is placed between the V-shaped structure formed by a pair of mold blocks, it first contacts with the fixed mold block 2 therein, and then adjusts the adjustable mold block 3 to make it contact with the corresponding position of the round ingot 100, so as to compensate for the situation that the multiple fixed mold blocks 2 cannot support the round ingot 100 with irregular circular contour.

[0036] See also Figures 1 to 4 In one embodiment, there are several groups of fixed blocks 2 and adjustable blocks 3, and each group of fixed blocks 2 or each group of adjustable blocks 3 includes a pair of fixed blocks 2 or adjustable blocks 3 arranged symmetrically along the second direction and with a spacing. That is to say, in the embodiment of the present invention, each group of mounting holes 10, each group of fixed blocks 2 and each group of adjustable blocks 3 are distributed along the first direction, and a pair of mounting holes 10, a pair of fixed blocks 2 and a pair of adjustable blocks 3 in each group are arranged parallel to the second direction.

[0037] Furthermore, each group of adjustable blocks 3 can be moved along the second direction to adjust the spacing of each group of adjustable blocks 3. That is, on the fixed plate 1, the distance between each group of mounting holes 10 is greater than the width of a pair of adjustable blocks 3 or a pair of fixed blocks 2 (that is, in the second direction).

[0038] Specifically, in the embodiment of the present invention, the round ingot 100 is placed in the bottom support. To maintain the stability of the support, the center of gravity height can be lowered. In this way, in the radial direction of the round ingot 100, that is, in the second direction, there is a spacing between the pair of fixed blocks 2 and the pair of adjustable blocks 3 in each group of blocks. Figure 2 and Figure 3 , the bottom of the fixed mold block 2 and the adjustable mold block 3 are respectively mounted on the fixed plate 1 through the fixed bracket 21, so that the bottom of the mold block is higher than the surface of the fixed plate 1 to form a sunken space, thereby making the bottom of the placed round ingot 100 drop below the bottom end of the mold block. At the same time, the spacing between the fixed mold blocks 2 can be used to adapt to round ingots 100 of different diameters by making the bottom of the placed round ingot 100 drop a corresponding size between the bottoms of the mold blocks, adjusting the spacing of the V-blocks in the second direction, or adjusting the angle between the V-blocks.

[0039] See also Figure 3 and Figure 4In one embodiment, the adjustable mold block 3 includes a mold block body 30, a supporting mechanism and a driving mechanism, the supporting mechanism includes a lower bracket 301 installed above the fixed plate 1 and an upper bracket 302 installed below the mold block body 30, as well as a first supporting block 311 installed below the upper bracket 302 and a second supporting block 312 installed above the lower bracket 301, and the first supporting block 311 and the second supporting block 312 are slidably connected along the second direction; the driving mechanism is installed on the lower bracket 301 or the second supporting block 312 and is transmission-connected to the mold block body 30 to drive the first supporting block 311 and the second supporting block 312 to slide relative to each other.

[0040] Furthermore, a limiting block 33 is installed on one end of the second supporting block 312 away from the driving mechanism. The limiting block 33 allows the first supporting block 311 to pass through it and is used to limit the stroke of the first supporting block 311 .

[0041] Furthermore, the driving mechanism includes a bearing seat 321, a fixed support 322 and a lead screw 323, the bearing seat 321 is mounted on the second support block 312; the fixed support 322 is mounted on the block body 30; the lead screw 323 is mounted on the bearing seat 321, and a driving member 324 is installed at the end away from the block body 30, and is transmission-connected to the fixed support 322 at the side close to the block body 30.

[0042] Specifically, in the embodiment of the present invention, the adjustable mold block 3 realizes the movement of the mold block body 30 supporting the round ingot 100 through the support mechanism and the driving mechanism, and the first support block 311 and the second support block 312 in the support mechanism are slidably connected to each other, and the first support block 311 is connected to the mold block body 30 through the upper bracket 302, and the second support block 312 is connected to the driving mechanism. In this way, the first support block 311 and the second support block 312 are pulled by the driving mechanism to move relative to each other, thereby driving the mold block body 30, that is, the adjustable mold block 3, to realize adjustable movement in the second direction, so as to adapt to different diameter sizes of the round ingot 100.

[0043] Furthermore, the driving mechanism uses a lead screw 323 to control the movement of the adjustable mold block 3. The lead screw is installed on the bearing seat 321 to realize rotation, and is connected to the mold block body 30 through a fixed support 322. The fixed support 322 is fixedly connected to the mold block body 30 on one hand, and is installed on the lead screw 323 through a nut installed on the other hand. In this way, a pair of lead screws 323 driving the mold block body 30 is formed.

[0044] The lead screw 323 is connected to the fixed support 322 by a thread, the lead screw 323 is equipped with a bearing, the lead screw 323 fixed support 322 is fixed to the upper support block of the adjustable mold block 3 by bolts, and the lead screw 323 is connected to the hand wheel by a key. The lead screw 323 is driven to rotate by turning the hand wheel, thereby driving the adjustable mold block 3 to move left and right; the distance between the two adjustable mold blocks 3 is changed by adjusting the hand wheel, so as to achieve the positioning control of the round ingot 100.

[0045] For more details, please see the attached Figure 3 The adjustable mold block 3 is assembled to the mounting hole 10 of the fixed plate 1 through the bracket 31 at the bottom thereof, and the mold block body 30 is also installed in an inclined posture through the corresponding bracket 31, and the height of the bracket 31 is used to form a space between a pair of adjustable mold blocks 3 to accommodate the bottom of the round ingot 100. At the same time, a supporting mechanism and a driving mechanism are installed on the bottom bracket 31, and a limit block 33 is installed on the second supporting block 312 at the end close to each other in the pair of adjustable mold blocks 3 to limit the moving range of the adjustable mold block 3 and prevent it from being separated from the traction stroke of the driving mechanism.

[0046] Please see attached Figure 3 and Figure 4 In the embodiment of the present invention, the adjustable mold block 3 mainly includes a mold block body 30 and a pad 4 thereon, a first support block 311 and a second support block 312, a lead screw 323, a fixed support 322, a limit block 33, a protective cover 34, a driving member 324 such as a hand wheel, and a bearing seat 321. A slideway groove is provided at the upper end of the first support block 311 of the adjustable mold block 3, and a slideway convex groove is provided at the lower end of the second support block 312 of the adjustable mold block 3. The two are connected and contacted by the slideway. The limit block 33 installed thereon is connected and fixed to the second support block 312 of the adjustable mold block 3 by bolts. Under the action of the limit block 33 and the slideway, the moving range of the first support block 311 of the adjustable mold block 3 is limited to prevent the fixed support 322 from being separated from the lead screw 323. The adjustable block can adjust the block position by turning the hand wheel, and the lead screw 323 is self-locked after being adjusted to the predetermined position. The two blocks of a pair of adjustable blocks 3 can be adjusted separately by the hand wheel, which can better support and fix the round ingot 100. Among them, the components of the bottom support can be made of steel, plate, etc., with a simple structure, and simple and convenient later maintenance. It can be used in conjunction with the matching round ingot 100 hanger and wire cutting equipment.

[0047] See also Figure 3 and Figure 4 In one embodiment, the adjustable block 3 further includes a protective cover 34 , which is mounted on the bearing seat 321 and the fixed support 322 and covers the lead screw 323 .

[0048] Furthermore, the angle between the fixed mold block 2 and the adjustable mold block 3 and the horizontal plane of the fixed plate 1 is less than 45°.

[0049] Furthermore, pads 4 are installed on the surfaces of the fixed mold block 2 and the adjustable mold block 3 .

[0050] Specifically, for the transmission components in the driving mechanism, such as the lead screw 323 and the bearing seat 321 and the fixed support 322 engaged therewith, a protective cover 34 is installed outside the lead screw 323 to avoid pollution in the processing process and the environment of the round ingot 100. The protective cover 34 shell is fixed to the first support block 311 of the adjustable block 3 by bolt connection, and a telescopic protective cover of the lead screw 323 is also installed between the bearing seat 321 and the first support block 311 of the adjustable block 3, and is respectively connected and fixed to the bearing seat 321 and the first support block 311 of the adjustable block 3 by bolts. The telescopic protective cover of the lead screw 323 and the protective cover 34 of the adjustable block 3 can protect the internal lead screw 323 and other components, and can also prevent water and dust pollution.

[0051] In the embodiment of the present invention, the upper ends of the adjustable mold block 3 and the fixed mold block 2 are both provided with a polyurethane pad 4, which can play a buffering role when the transfer sling places the round ingot 100 on the mold block, and at the same time separate the round ingot 100 from the mold block to avoid the mold block surface directly contacting the silicon ingot surface and polluting the silicon ingot surface. The mold block in the embodiment of the present invention has an angle of 35° with the horizontal plane, which requires less space and has a more compact layout. At the same time, it also reserves more space for the transfer sling of the round ingot 100, and the contact area with the surface of the round ingot 100 is larger, making the sling safer and more reliable when transporting.

[0052] For more details, please see the attached Figure 2 and Figure 3 The inclination angles of the fixed mold block 2 and the adjustable mold block 3 are set to 35°, which can reduce their height parameters compared to the general 45° inclination setting. On the one hand, the center of gravity height of the ingot 100 after placement can be further reduced, and on the other hand, the space occupied in the height direction can be released, which is convenient for hoisting operations. Similarly, for the irregular circular contour of the ingot 100, the inclination angles of the mold blocks can also be set to different angles, for example, the inclination angle of the fixed mold block 2 is set to 30°, and the inclination angle of the adjustable mold block 3 is set to 40°, so that the inclination angle of the adjustable mold block 3 is greater than the inclination angle of the fixed mold block 2, so that the fixed mold block 2 can bear more weight of the ingot 100, and the force of the adjustable mold block 3 on the ingot 100 is more used for clamping and fixing. Similarly, the inclination angle of the adjustable mold block 3 can also be made smaller than the inclination angle of the fixed mold block 2, so as to increase the supporting effect of the adjustable mold block 3 on the ingot 100.

[0053] It should be noted that the pad 4 installed on the surface of each mold block (including the fixed mold block 2 and the adjustable mold block 3 in this embodiment) is a polyurethane pad 4, which can play a buffering role when the ingot 100 is placed on the mold block using a hanger, and separate the ingot 100 from the mold block to avoid direct contact between the ingot 100 and the mold block and contamination of the ingot 100.

[0054] The present invention also provides a method for using an adjustable round ingot support, comprising:

[0055] Positioning step: placing the round ingot 100 on the bottom bracket by means of a sling and only contacting the fixed block 2 of the bottom bracket, while the adjustable block 3 of the bottom bracket is at the initial position and does not contact the round ingot 100;

[0056] Fixing step: by operating the driving member 324 of the adjustable mold block 3, the supporting block of the adjustable mold block 3 is driven to move closer to the ingot 100 to fine-tune the position of the ingot 100, and after the adjustable mold block 3 contacts the ingot 100, the driving member 324 is stopped and self-locked to complete the fixation of the ingot 100.

[0057] See also Figures 1 to 4 As shown, in the embodiment of the present invention, the adjustable round ingot 100 block bottom support includes a fixed block 2, an adjustable block 3, and a block fixing plate 1. The block fixing plate 1 is reserved with multiple groups of block mounting holes 10. The distance between the blocks can be adjusted according to the length of the round ingot 100. The block can be fixed to the machine tool worktable 101 by bolt connection, or other methods can be used for connection and fixing. The round ingot 100 can be placed on the bottom support block. Among them, the adjustment of the left and right upper support blocks (the upper support block is the block body 30 in the above embodiment) of the adjustable block 3 is independent of each other and does not interfere with each other. The screw 323 can be driven by rotating the hand wheel. The fixed support 322 of the screw 323 is connected to the upper support block (left and right symmetric) of the adjustable block 3 by bolts. The screw 323 rotates while driving the upper support block (left and right symmetric) of the adjustable block 3 to move.

[0058] Specifically, the upper end of the lower support block of the adjustable block 3 (the lower support block is the first support block 311 and the second support block 312 in the above embodiment) is provided with a slide groove, and the lower end of the lower support block of the adjustable block 3 is provided with a slide convex groove, and the two are connected and contacted through the slide, and the inner limit block 33 is connected and fixed to the lower support block of the adjustable block 3 by bolts. Under the action of the limit block 33 and the slide, the left and right movement range of the upper support block of the adjustable block 3 is limited within a certain range.

[0059] Furthermore, the protective cover 34 of the adjustable block 3 is fixed at the front and rear of the second support block 312 in the adjustable block 3 by bolt connection. A telescopic protective cover of the lead screw 323 is provided between the bearing seat 321 and the upper bracket 302 in the adjustable block 3, and is respectively connected and fixed to the bearing seat 321 and the upper bracket 302 in the adjustable block 3 by bolts. The telescopic protective cover of the lead screw 323 and the protective cover 34 of the adjustable block 3 can protect the internal lead screw 323 and other components, and can also block water and dust.

[0060] More specifically, when in use, the ingot 100 is first placed on the bottom support by a lifting device such as a bridge crane. At this time, the ingot 100 of polycrystalline silicon material is only in contact with the fixed block 2 in the bottom support, and the support block (i.e., the first support block 311 in the above embodiment) installed on the adjustable block 3 is at the initial position, and the adjustable block 3 and the pad 4 thereon are not in contact with the silicon material ingot 100. Then, by operating the driving member 324 of one of the adjustable blocks 3, for example, manually adjusting and rotating the hand wheel, the hand wheel drives the lead screw 323 of the driving member 324, and then drives the support block on the adjustable block 3 to move close to the ingot 100, so as to achieve fine adjustment of the position of the ingot 100. When the pad 4 of the adjustable block 3 contacts the ingot 100, the hand wheel stops rotating, and the lead screw 323 of the driving member 324 is self-locked. Similarly, the positions of the support blocks on the remaining three adjustable mold blocks 3 are adjusted until the pads 4 of the adjustable mold blocks 3 contact the surface of the polysilicon ingot 100 , and the hand wheel is stopped to complete the fixation of the polysilicon ingot 100 .

[0061] In summary, the adjustable round ingot base and its use method provided by the present invention support the round ingot by means of fixed blocks and adjustable blocks installed on the base fixing plate, so that the base can be detached, the spacing between the blocks is adjustable, the blocks can be flexibly adjusted for round ingots of different lengths, and the processing and placement of round ingots of various lengths can be satisfied. Moreover, the inclined surface of the block and the horizontal plane are set at a smaller angle, so that the overall layout is more compact, more space is reserved for the sling, the contact area with the round ingot surface is larger, and the sling is safer and more reliable when transporting.
