Description

Technical Field

[0001] The present invention relates to the technical field of metal surface treatment, and particularly to a movable tool rest. Background Art

[0002] Titanium alloy has excellent properties such as high strength, good corrosion resistance, and high heat resistance, and is currently used in the manufacture of mobile phone frames. The titanium alloy base material for mobile phone frame manufacturing is generally stored or transported in the form of coil bars, and the cross-section of the titanium alloy coil bar is generally rectangular. The titanium alloy coil bar is prone to oxidation to form oxide scale in the air. Before processing, a peeling device is required to strip and remove the oxide scale on the surface of the titanium alloy coil bar, which is also called peeling operation.

[0003] Please refer to Figure 15 , Figure 15 which is a schematic structural diagram of a tool for removing oxide scale in the prior art. A tool hole 31 is machined in the middle of the existing tool 30, and the inner wall of the tool hole 31 forms a cutting edge 32. When in use, the coil bar is passed through the tool hole 31, and during the process of pulling the coil bar, the oxide scale on the surface of the coil bar is stripped off by using the cutting edge 32. However, the following problems exist in the use of this tool: 1. Before the peeling operation, the cross-sectional area of the rear section of the tool hole is smaller than the cross-sectional area of the coil bar. It is necessary to first grind the end of the coil bar to a size adapted to the tool hole before the end of the coil bar can be passed through the tool hole to facilitate the pulling of the coil bar, which increases the grinding process and reduces the production efficiency; 2. After the tool is worn after long-term use, the peeling effect is affected. It is necessary to remove the whole tool for replacement, with high replacement cost and low replacement efficiency; 3. If the tool is worn or has a notch during the peeling process of the coil bar, it is necessary to pull out the peeled coil bar from the tool hole in the reverse direction and then replace the tool, which is extremely inconvenient to operate and greatly reduces the production efficiency.

[0004] Therefore, it is necessary to improve the tool for removing oxide scale. Summary of the Invention

[0044] Please refer to Figures 1 to 5 , Figure 1 , which is a schematic structural diagram of the movable tool rest according to Embodiment 1 of the present invention, Figure 2 , which is an exploded view of the movable tool rest according to Embodiment 1 of the present invention,Figure 3 This is a sectional view of the movable tool rest according to Embodiment 1 of the present invention. Figure 4 This is another sectional view of the movable tool rest according to Embodiment 1 of the present invention. Figure 5 This is a sectional view of the movable tool rest during the peeling operation according to Embodiment 1 of the present invention.

[0045] The present invention provides a movable tool rest, which includes a first tool rest 10. The first tool rest 10 includes a first tool holder 11, a first tool 12, a second tool 13, a first auxiliary positioning block 14, a first fastener 15 and a second fastener 16.

[0046] The first tool holder 11 has a first top surface 1101, a first bottom surface 1102, a first side surface 1103, a second side surface 1104, a third side surface 1105 and a fourth side surface 1106. The first top surface 1101 is parallel to the first bottom surface 1102, the first side surface 1103 is parallel to the third side surface 1105, and the second side surface 1104 is parallel to the fourth side surface 1106.

[0047] The first tool holder 11 is provided with a first installation channel 1107, a second installation channel 1108, a first auxiliary positioning channel 1109, a first fastening hole 1110, a second fastening hole 1111 and a first feed channel 1112. The first installation channel 1107, the second installation channel 1108 and the first auxiliary positioning channel 1109 respectively extend from the first side surface 1103 to the third side surface 1105 along the first direction X. The first installation channel 1107 and the second installation channel 1108 are oppositely arranged. The first auxiliary positioning channel 1109 is communicated with the second installation channel 1108, and the first auxiliary positioning channel 1109 is located between the fourth side surface 1106 and the second installation channel 1108. The first fastening hole 1110 is arranged along the second direction Y between the second side surface 1104 and the first installation channel 1107; the second fastening hole 1111 is arranged along the second direction Y between the fourth side surface 1106 and the first auxiliary positioning channel 1109. The first feed channel 1112 is arranged along the third direction Z between the first top surface 1101 and the first bottom surface 1102, and the first feed channel 1112 is respectively communicated with the first installation channel 1107 and the second installation channel 1108; wherein, the first direction X, the second direction Y and the third direction Z are perpendicular to each other pairwise.

[0048] The first tool 12 and the second tool 13 are in a strip-shaped structure. The first tool 12 is arranged in the first installation channel 1107, the second tool 13 is arranged in the second installation channel 1108, and the first auxiliary positioning block 14 is arranged in the first auxiliary positioning channel 1109. The first tool 12 and the second tool 13 respectively have cutting edges. The cutting edges of the first tool 12 and the second tool 13 are respectively exposed at the top feed openings of the first feed channel 1112. The cutting edges of the first tool 12 and the second tool 13 are opposite to each other, and a gap for the passing of the wire rod is left between them.

[0049] The first fastener 15 is disposed at the first fastening hole 1110 for fixing the first tool 12; the second fastener 16 is disposed at the second fastening hole 1111 for fixing the first auxiliary positioning block 14 and the second tool 13.

[0050] The structure of the first installation channel 1107 matches the structure of the first tool 12, so that the first tool 12 can move along the first direction X in the first installation channel 1107 in a non-fixed state. At the same time, along the second direction Y, the width of the second installation channel 1108 is slightly larger than the width of the second tool 13, and the width of the first auxiliary positioning channel 1109 is slightly larger than the width of the first auxiliary positioning block, so that the second tool 13 and the first auxiliary positioning block 14 can not only move along the first direction X in a non-fixed state, but also advance and retreat a certain distance along the second direction Y, so as to facilitate the retreat of the second tool 13 for the insertion of the wire rod 40 before the peeling operation, and fix the second tool 13 and the first auxiliary positioning block 14 with the second fastener 16 after the wire rod 40 is inserted. After fixing, the second fixing member 16 abuts against the first auxiliary positioning block 14, the first auxiliary positioning block 14 abuts against the second tool 13, the second tool 13 moves rightward to the XZ-direction side wall of the second installation channel 1108 at most, and the cutting edge portion of the second tool 13 is exposed at the top feed port of the first feed channel 1112 to peel the wire rod.

[0051] The movable tool rest structure of the present invention is ingeniously designed and convenient to operate: before the peeling operation, loosen the second fastener 16 to make the second tool 13 retreat a certain distance along the Y direction, the wire rod can be inserted through the first feed channel 1112, and then after tightening the second fastener 16, the second tool 13 and the first auxiliary positioning block 14 can be fixed, and after fixing, the cutting edge portion of the second tool 13 faces the top feed port of the first feed channel 1112, and the cutting edge portion of the first tool 12 is symmetrical with the cutting edge portion of the second tool 13. Then, by pulling the wire rod under the first tool holder 11, the oxide skin on both sides of the wire rod can be peeled off by using the cutting edge portions of the first tool 12 and the second tool 13, omitting the process of grinding the end of the wire rod, and the production efficiency can be improved. The tool in the movable tool rest is designed as a long strip structure, and the cutting edge portion extends along the length direction of the tool. When the cutting edge portion corresponding to the feed port is worn, the tool can be moved along the length direction of the tool to move the unused portion of the cutting edge portion to the feed port, that is, the tool can be used multiple times, thus greatly improving the utilization rate of the tool, prolonging the service life of the tool, and reducing the production cost. In addition, when the tool is worn or has a notch during the peeling process, the fastener can be loosened to withdraw part of the wire rod, move the tool to make the unused portion of the cutting edge portion reach the feed port and then continue to peel the wire rod, that is, rework and tool replacement operations can also be carried out during the peeling operation, which can improve the production efficiency and save operation time.

[0052] In some preferred embodiments of the present invention, the cross-sections of the first cutting tool 12 and the second cutting tool 13 are respectively polygons, including but not limited to shapes such as triangles, parallelograms, rectangles, isosceles trapezoids, etc., and at least one angle of the polygon is set as a cutting edge portion.

[0053] In a preferred embodiment of the present invention, the angles of the cutting edge portions of the first cutting tool 12 and the second cutting tool 13 are 70° to 90°. In some embodiments, the angle of the cutting edge portion can be 70° to 80°, which can achieve a better cutting effect.

[0054] Please refer to Figure 3 , in Embodiment 1 of the present invention, the cross-sections of the first cutting tool 12 and the second cutting tool 13 are both isosceles trapezoids, and both acute angles of the isosceles trapezoid are set as cutting edge portions. In this way, each cutting edge portion can move its position and be used multiple times, and after each cutting edge portion is worn out after being used multiple times, it can be replaced with another cutting edge portion to work, thereby greatly improving the utilization rate of the cutting tool, extending the service life of the cutting tool, and reducing the production cost. The angles α of the two cutting edge portions 1 can be 70° to 80° to ensure the cutting effect.

[0055] Please refer to Figure 6 , Figure 6 is a sectional view of the first cutting tool in the movable tool rest of Embodiment 2 of the present invention. In Embodiment 2 of the present invention, the cross-sections of the first cutting tool 12 and the second cutting tool 13 are both rectangles, and all four corners of the rectangle can be set as cutting edge portions 121. The angle α of each cutting edge portion 2 is 90°, so as to further improve the utilization rate of the cutting tool.

[0056] Please refer to Figure 7 , Figure 7 is a sectional view of the first cutting tool in the movable tool rest of Embodiment 3 of the present invention. In Embodiment 3 of the present invention, the first cutting tool 12 and the second cutting tool 13 can be Figure 6 a hexagonal structure that is narrow in the middle and wide on both sides as shown, and the corresponding four acute angles can be set as cutting edge portions 121. The angle α of the cutting edge portion 3 can be 70° to 80°, which can not only improve the utilization rate of the cutting tool, extend the service life of the cutting tool, and reduce the production cost, but also achieve a better cutting effect.

[0057] However, the present invention is not limited thereto. In other embodiments, the structure of the cutting tool, the angle of the cutting edge portion, etc. can also be reasonably set according to requirements.

The central axes of the first avoidance holes 1113 are parallel to the first direction X. In this way, during the installation and movement of the cutting tools, the tips of the cutting edges can pass through the corresponding first avoidance holes 1113, which can avoid the problem of damage to the cutting edges caused by collision and extend the service life of the cutting tools.

[0059] In application, along the first direction X, the lengths of the first cutting tool 12 and the second cutting tool 13 are at least twice the width of the first feeding channel 1112, ensuring that the same cutting tool can be used at least twice. When the cutting edge at the feeding port is worn or has a notch, the cutting tool can be moved so that the unused part of the cutting edge moves to the feeding port to improve the utilization rate of the cutting tool and reduce the production cost.

[0060] In some preferred embodiments of the present invention, a guiding inclined surface 1114 is provided at the top feeding port of the first feeding channel 1112.

At the same time, along the first direction X, the width of the fourth installation channel 2109 is slightly larger than the width of the fourth cutter 23, and the width of the second auxiliary positioning channel 2110 is slightly larger than the width of the second auxiliary positioning block 24, so that the fourth cutter 23 and the second auxiliary positioning block 24 can not only move along the second direction Y in a non-fixed state, but also move forward and backward a certain distance along the first direction X, thereby facilitating the fourth cutter 23 to retreat before the peeling operation to allow the wire rod 40 to be inserted, and the fourth cutter 23 and the second auxiliary positioning block 24 can be fixed by the fourth fastener 26 after the wire rod 40 is inserted. After fixation, the fourth fastener 26 is tightly against the second auxiliary positioning block 24, and the second auxiliary positioning block 24 is tightly against the fourth tool 23. The fourth tool 23 moves to the YZ direction side wall of the fourth mounting channel 2109 at most, and the blade of the fourth tool 23 is exposed at the opening groove 2107 to peel the wire rod.

[0067] See also Figure 9 The first cutter 12, the second cutter 13, the third cutter 22, and the fourth cutter 23 can form a rectangular channel of the required size. Before the peeling operation, loosen the second fastener 16 and the fourth fastener 26, and the wire rod can be passed through the first feed channel 1112 and the second feed channel 2113 in sequence. After tightening the second fastener 16 and the fourth fastener 26, the second cutter 13 and the first auxiliary positioning block 14, the fourth cutter 23 and the second auxiliary positioning block 24 can be fixed. After that, the wire rod is pulled under the second cutter seat 21, and the blades of the first cutter 12 and the second cutter 13 can be used to peel off the oxide scale on both sides of the wire rod, and the blades of the third cutter 22 and the fourth cutter 23 can be used to peel off the oxide scale on the other two sides of the wire rod. The peeled oxide scale waste can be screwed out from the guide slope 1114 and the opening groove 2107 respectively. The cooperation between the first tool holder 10 and the second tool holder 20 can greatly improve production efficiency and reduce production costs. At the same time, when the tool is worn or notched during the peeling process, the fasteners can be loosened to partially withdraw the wire rod, and the tool can be moved so that the unused part of the blade reaches the feed channel before continuing to peel the wire rod. That is, rework and tool replacement operations can also be performed during the peeling operation, which can improve production efficiency and save operation time.

[0068] Correspondingly, the cross-sections of the third tool 22 and the fourth tool 23 can be polygonal, including but not limited to triangle, parallelogram, rectangle, isosceles trapezoid, etc., and at least one corner of the polygon is set as a blade portion.

[0069] Furthermore, the angles of the blades of the third tool 22 and the fourth tool 23 can be set to 70° to 80° to achieve a better cutting effect.

[0070] Furthermore, along the second direction Y, the length of the third tool 22 and the fourth tool 24 is at least twice the width of the second feed channel 2113, ensuring that the same tool can be used at least twice. When the blade portion at the second feed channel 2113 is worn or has a notch, the tool can be moved so that the unused portion of the blade portion is moved to the second feed channel 2113, thereby improving the tool utilization rate and reducing production costs.

[0071] In some other embodiments of the present invention, the second tool holder 20 further includes a connecting plate 271, a first adjusting rod 272 and a second adjusting rod 273. The connecting plate 271 is fixed to the sixth side surface 2104 of the second tool holder 21 by a fixing pin. The first adjusting rod 272 and the second adjusting rod 273 are respectively arranged on the connecting plate 271. The central axes of the first adjusting rod 272 and the second adjusting rod 273 are parallel to the second direction Y. The first adjusting rod 272 extends into the third installation channel 2108 and abuts against the third tool 22. The second adjusting rod 273 extends into the fourth installation channel 2109 and abuts against the fourth tool 23. When the third tool 22 or the fourth tool 24 is worn, the third fastener 25 or the fourth fastener 26 can be loosened, and the position of the third tool 22 can be adjusted by using the first adjusting rod 272, or the position of the fourth tool 23 can be adjusted by using the second adjusting rod 273, so that the unused portion of the blade of the tool moves to the second feed channel 2113.

[0072] See also Figure 13 In a preferred embodiment of the present invention, the third installation channel 2108 is provided with a second avoidance hole 2114 at the blade portion of the third tool 22, and the fourth installation channel 2109 is provided with a second avoidance hole 2114 at the blade portion of the fourth tool 23, and the central axis of the second avoidance hole 2114 is parallel to the second direction Y. In this way, during the installation and movement of the tool, the tip of the blade portion can pass through the corresponding second avoidance hole 2114, which can avoid the problem of blade portion damage caused by collision and extend the service life of the tool.

[0073] In application, the first fastener 15, the second fastener 16, the third fastener 17, the fourth fastener 18, the first adjustment rod 272, and the second adjustment rod 273 can be made of parts such as screws and nuts, and can be reasonably selected according to actual needs.

[0074] In summary, the present invention provides a movable tool rest, which can be applied to the surface treatment of metal wire rods. The structure of the movable tool rest is ingeniously designed, eliminating the process of grinding the wire rods, and improving production efficiency. The tool is designed as a long strip structure, and the cutting edge extends along the length direction of the tool. When the cutting edge corresponding to the feeding port is worn, the tool can be moved along the length direction of the tool, so that the unused part of the cutting edge moves to the feeding port, thus greatly improving the utilization rate of the tool, prolonging the service life of the tool, and reducing production costs. When the tool is worn or has a notch during the peeling process, only by loosening the fastener can the wire rod part be retracted, and after moving the tool to make the unused part of the cutting edge reach the feeding port, the wire rod can be peeled continuously, which can improve production efficiency and save operation time.

It must be pointed out that the disclosed embodiments do not limit the scope of the present invention. On the contrary, modifications and refinements made without departing from the spirit and scope of the present invention fall within the scope of the patent protection of the present invention.
