Description

Technical Field

[0001] The present application relates to the technical field of smelting ingots, and in particular to a device for marking the center hole position of the end face of a smelting ingot. Background Art

[0002] Ingot smelting is the process of pressing metal raw materials such as sponge titanium into electrode blocks, welding multiple pressed electrode blocks into an integral electrode, and then placing them in a smelting furnace for smelting. After smelting, ingots can be formed in the smelting furnace, and then the ingots can be machined to form various metal products. It is widely used in the process of forming products from metal raw materials.

[0003] After the ingot is smelted and formed, its surface is usually rough and uneven, and its surface and end faces need to be machined (such as turning). However, due to the long single smelting cycle and high energy consumption, the overall size of the single smelted ingot is usually large. In addition, since the smelting is usually metal smelting, the overall weight of the ingot is large, usually measured in tons. Therefore, when turning it, the chuck on one side of the lathe is difficult to clamp and rotate it firmly. Except for the end, the other parts of the ingot are in a suspended state, which will cause deflection of the chuck's positioning point, including the deflection during the later rotation (see the attached manual). Figure 2 Therefore, for heavy ingot processing, center holes are usually opened on both end faces. The machine tool chuck and the rear tailstock bracket are embedded in the center holes of the ingot end faces to support the ingot from both ends, thus solving the problem of unstable clamping on one side.

[0004] Currently, the center hole of smelted ingots is difficult to locate due to their rough surface and generally circular cross-section. This often requires manual determination of the approximate location of the center hole on the end face and subsequent drilling. This deviation between the manually determined center hole location and the actual hole location can cause rotational runout during the clamping and rotation process of the ingot. This leads to inconsistent tool cutting depths, resulting in increased cutting waste. Furthermore, inconsistent cutting thickness can accelerate tool damage, increasing processing costs. Summary of the Invention

[0005] In response to the above-mentioned problems, the present application aims to provide a device for depicting the center hole position of the end face of a smelting ingot, which can find a relatively accurate center point on the end face of the ingot, solve the problem of deviation in the center point currently found manually, and the problem of rotational deflection during the later ingot clamping processing, as well as solve the problem of increased waste caused by deflection.

[0006] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is as follows: a device for engraving the center hole position of the end face of a smelting ingot, characterized in that: the engraving device has a contact support point in contact with the circumferential surface of the ingot, and a engraving point in contact with the non-circular area of ​​the end face of the ingot, and a limiting body for limiting the contact support point can also be movably arranged on the circumferential surface of the ingot.

[0007] Preferably, the carving device is a carving rod with a V-shaped structure, with the two ends of the carving rod being contact support points and carving points respectively, and the contact support points are perpendicular to the circumferential surface of the ingot.

[0008] Preferably, the limiting body is a limiting block with an arc shape flat on the circumferential surface of the ingot, and a limiting conical groove movably embedded in the contact support point is provided on the outer surface of the limiting block.

[0009] Preferably, a positioning groove is provided on the limiting block on one side of the limiting conical groove, and a fastening rope looped around the circumferential surface of the ingot is sleeved in the positioning groove.

[0010] The beneficial effect of the present application is that the carving device can be used to find a more accurate center point on the end face of the ingot, thereby solving the problem of deviation in the center point currently found manually and the problem of rotational deflection during the later ingot clamping processing, as well as solving the problem of increased waste caused by deflection.

[0011] The limiting body can limit the sliding deviation of the engraving device on the circumferential surface when in use, thereby ensuring the accuracy of finding the center point. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] In order to enable ordinary technicians in this field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0025] Refer to the attached Figures 1 to 11 The depicted device is a device for marking the center hole of the end face of a smelting ingot. The device has a contact support point a1 that contacts the circumferential surface of the ingot, and a marking point a2 that contacts the non-circular area of ​​the end face of the ingot. When the marking device is used to find the center point of the end face of the ingot, as shown in FIG. Figure 4 As shown, the contact support point a1 of the carving device is placed against any position on the circumferential surface of the ingot and the contact point is kept stable; then the carving point a2 is brought into contact with the end surface of the ingot and Figure 5 As shown, the contact support point a1 is used as the rotation fulcrum to drive the engraving point a2 to rotate left and right, and an arc is engraved on the end face of the ingot ( Figure 5 Then, the contact position of the contact support point a1 is changed on the circumferential surface of the ingot ( Figure 5 In the same way, draw the second arc, and then draw the area enclosed by multiple arcs in the same way ( Figure 6 Then connect the intersection points of each arc to form a Figure 6 Illustration of the center hole location shown on the right.

[0026] In the above process of single arc drawing on the end face of the ingot, since the drawing point a2 needs to deflect along the arc, the contact support point a1 on the circumferential surface of the ingot also deflects left and right, which will cause the contact support point a1 to slide on the circumferential surface ( Figure 7(as shown by the middle arrow), which will affect the accuracy of arc engraving and the deviation after the final center hole position is determined, resulting in deviation after the center hole is drilled in the later stage, affecting the problem of rotational deflection when the ingot is clamped on the machine tool for processing. Therefore, to solve this problem, a limiter is also movably provided on the circumferential surface of the ingot to limit the contact support point a1. This limiter can limit the sliding deviation of the contact support point a1 on the circumferential surface when the engraving device is in use, thereby ensuring the accuracy of the center point search. The movable limiter is used for engraving operations on different circumferential surfaces.

[0027] Specifically, such as Figure 3-4 As shown, the carving device is a V-shaped carving rod 1, with contact support point a1 and carving point a2 at both ends of the carving rod 1, and the contact support point a1 is perpendicular to the circumferential surface of the ingot. Figure 4 As shown, the characterization process is as follows Figure 5-6 As shown, the contact support point a1 is pressed against the circumferential surface of the ingot, the engraving point a2 segment is deflected in an arc, and at the same time, it is in contact with the end face of the ingot, so that a single arc can be engraved on the end face. Then, the contact position of the contact support point a1 on the circumferential surface is changed. In the same way, multiple arcs with a closed structure can be engraved. Then, the intersecting arcs are connected by straight lines, so that they intersect and converge at the center point. A hole is drilled at this point to obtain the center hole of the end face of the ingot, which is used for end face rotation support in subsequent processing.

[0028] Specifically, such as Figure 8-10 As shown, the limiting body is a limiting block 2 that is flatly attached to the circumferential surface of the ingot in an arc shape, and a limiting conical groove 2a is provided on the outer surface of the limiting block 2 to be movably embedded in the contact support point a1. Since the surface of the smelted ingot is relatively rough, the inner surface of the limiting block 2 is set to a rough surface structure, and then after it contacts the circumferential surface of the ingot, the contact friction force can effectively limit the sliding of the limiting block 2 on the circumferential surface, thereby improving the stability of the support for the engraving rod 1. After the limiting block 2 contacts the circumferential surface of the ingot, the contact support point a1 is then embedded in the limiting conical groove 2a, which is a conical opening to facilitate the left and right deflection of the contact support point a1 (such as Figure 10 As shown), the arc of a certain length depicting point a2 is completed.

[0029] After a single arc is completed, the carving rod 1 and the limit block 2 are slid as a whole on the circumferential surface to carry out the carving operation of the next arc.

[0030] In order to further improve the stability of the stop block 2 and the carving rod 1 against each other on the circumferential surface of the ingot, Figure 11As shown, a positioning groove 2b is provided on the limiting block 2 on one side of the limiting conical groove 2a, and a fastening rope 3 is provided in the positioning groove 2b, which is looped around the circumferential surface of the ingot. The fastening rope 3 is preferably an elastic rope. By utilizing its elasticity and through the positioning groove 2b, the limiting block 2 can be locked to the circumferential surface of the ingot. At the same time, when operating the carving rod 1, there is no need to support the limiting block 2, which facilitates the smooth deflection operation of the carving rod 1. After the single arc is carved, the limiting block 2 is slightly lifted to overcome the locking effect of the fastening rope 3. After the limiting block 2 is separated from the circumferential surface, the position of the limiting block 2 is adjusted along the circumferential direction. Then, the limiting block 2 is pressed against the circumferential surface again by the locking effect of the fastening rope 3 to carve the next arc. The carving operation of multiple arcs is completed in the same way.

[0031] In order to make the carving rod 1 suitable for the center hole finding operation of the end faces of ingots with different outer diameters, the carving rod 1 is set as a hinged structure in half, and the hinge is preferably passed through a hinge screw (not shown in the figure). After adjusting the distance between the contact support point a1 and the carving point a2 (the distance is usually slightly larger than the end face radius), it can be locked by the hinge screw, which avoids the problem that the distance between the contact support point a1 and the carving point a2 is less than the radius of the end face, so that the multiple carved arcs cannot intersect.

[0032] The principle of this application is: when searching for the center hole point of the end face of the smelting ingot, first make the limit block 2 contact with any position on the circumferential surface of the ingot (near the end face), then embed the fastening rope 3 into the positioning groove 2b, and put the fastening rope 3 as a whole around the circumferential surface of the ingot to tighten the limit block 2, and then embed the contact support point a1 of the engraving rod 1 into the limiting cone groove 2a, and then the engraving operation can be carried out.

[0033] When carving, with the contact support point a1 as the rotation fulcrum, the carving rod 1 is driven to deflect left and right while contacting the end face of the ingot, and a single arc can be carved on the end face. Then, the limit block 2 is slightly lifted to overcome the locking effect of the fastening rope 3. After the limit block 2 is separated from the circumferential surface, the position of the limit block 2 is adjusted along the circumferential direction. Then, the limit block 2 is pressed against the circumferential surface again through the locking effect of the fastening rope 3 to carve the next arc. The carving operation of multiple arcs is completed in the same way. The intersection points of the multiple arcs are then connected with straight lines to form the center hole site. The drilling operation is performed at this point, that is, the accurate center hole is formed.

[0034] The above shows and describes the basic principles, main features and advantages of this application. Without departing from the spirit and scope of this application, this application will also have various changes and improvements, which fall within the scope of this application.
