DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figures 1 to 7 In the embodiment of the present invention, a tool for turning a special-shaped welded pipe mold includes a tool body 100, and the tool body 100 includes a tool rod 110. The end of the tool rod 110 is provided with a base 130, and the top surface of the base 130 is provided with a support 120. The top surface of the support 120 is symmetrically provided with a plug-in slot 121, and a blade 300 is slidably inserted into the plug-in slot 121. Two side walls of the support 120 are symmetrically inserted with two locking modules 140. The end side of the tool rod 110 is rotatably connected to a clamping unit. Element 200, the clamping unit 200 includes a bidirectional screw rod 210, the two ends of the bidirectional screw rod 210 are respectively rotatably connected to the two inner side walls of the tool rod 110, the middle section of the outer wall of the bidirectional screw rod 210 is sleeved and fixed with a limit ring 211, the left and right ends of the bidirectional screw rod 210 have opposite thread rotation directions, the outer wall of the bidirectional screw rod 210 is symmetrically screwed with a clamping block 1 220 and a clamping block 2 221, the side wall of the tool rod 110 is rotatably connected to a handle 212, and the end of the handle 212 is fixedly connected to one end of the bidirectional screw rod 210.

[0025] Specifically, when installing the blade 300, the selected blade 300 is placed on the top surface of the support 120. Since the left and right threads of the bidirectional screw rod 210 are rotated in opposite directions, and the clamping block 1 220 and the clamping block 2 221 are respectively screwed together with the left and right outer walls of the bidirectional screw rod 210, when the handle 212 is turned clockwise, the clamping block 1 220 and the clamping block 2 221 will approach each other until the blade 300 is clamped. When removing the blade 300, the handle 212 is turned counterclockwise. At this time, the clamping block 1 220 and the clamping block 2 221 will move away from each other and no longer clamp the blade 300. This clamping method makes replacement and disassembly more convenient and quick, and does not require the use of tools. Example

[0026] like Figure 2-4 As shown, in this embodiment, the inner side walls of clamp block 1 220 and clamp block 2 221 are slidably connected with a number of bosses 222 at equal distances, the tail ends of the several bosses 222 are fixedly connected with return springs 2 223, the other ends of the several return springs 223 are respectively fixedly connected to the interior of clamp block 1 220 and clamp block 2 221, the inner top surface and inner bottom surface of clamp block 1 220 and clamp block 2 221 are slidably connected with a number of arc blocks 224 at equal distances, the tail ends of the several arc blocks 224 are fixedly connected with return springs 3 225, and the other ends of the several return springs 3 225 are respectively fixedly connected to the interior of clamp block 1 220 and clamp block 2 221.

[0027] In this embodiment, by providing a plurality of bosses 222 and return springs 223, when the clamping block 1 220 and the clamping block 2 221 gradually move closer to clamp the blade 300, the boss 222 will change automatically according to the shape of the blade 300, so that the clamping unit 200 can adapt to blades 300 of various shapes, solving the problem that when replacing blades 300 of different shapes, the tool body 100 also needs to be replaced, reducing the loss of turning tools in production and saving production resources. When the clamping block 1 220 and the clamping block 2 221 gradually move and clamp the blade 300, the arc block 224 can reduce the friction with the top surface of the blade 300, and under the elastic force of the return spring 3 225 and the return spring 2 223, the clamping force of the clamping block 1 220 and the clamping block 2 221 on the blade 300 is increased.

[0028] like Figure 5-6 As shown, in this embodiment, the bottom surface of the blade 300 is symmetrically fixedly connected with a plug-in block 310, and the opposite side walls of the two plug-in blocks 310 are provided with a polygonal groove 311. The two plug-in blocks 310 are respectively slidably plugged into the two plug-in grooves 121. The shape of the blade 300 includes but is not limited to a rectangle, a diamond, an ellipse, and a hexagon. The shank 110, the support 120 and the bottom of the table 130 are internally connected with a cooling channel, and the top surface of the bottom of the table 130 is provided with two cooling liquid nozzles 131.

[0029] During specific implementation, blades 300 of different shapes can adapt to different processing requirements, so that when the processing needs change, only different blades 300 need to be replaced, saving replacement time. The tool rod 110, the support table 120 and the bottom of the table 130 are internally connected with a cooling channel, and coolant flows through the cooling channel. The coolant can effectively absorb and take away the heat generated during the cutting process, significantly reducing the temperature of the blade 300 and the workpiece, preventing the blade 300 from being worn and the workpiece from being deformed due to overheating, thereby extending the service life of the blade 300, and two coolant nozzles 131 are provided on the top surface of the bottom of the table 130. The coolant can be sprayed from the coolant nozzle 131 to cool the tip of the blade 300. The coolant has a flushing effect, which can help clean the chips generated during the cutting process and keep the cutting area clean. Example

[0030] On the basis of the first embodiment, in order to fix the blade 300 more firmly and avoid deviation during processing.

[0031] like Figure 5-7 As shown, in this embodiment, the two locking modules 140 each include a round rod 141, and the two locking modules 140 are respectively slidably plugged into the left and right side walls of the support platform 120, and the facing ends of the two round rods 141 are fixedly connected with polygonal blocks 142, and the opposite ends of the two round rods 141 are fixedly connected with pull rings 143, and the outer walls of the two round rods 141 are rotatably sleeved with reset springs 144, and the two polygonal blocks 142 are respectively plugged into the two polygonal grooves 311.

[0032] During specific implementation, the polygonal block 142 usually extends into the interior of the insertion slot 121. When the blade 300 is installed, the two insertion blocks 310 are aligned and inserted into the two insertion slots 121. The side walls of the insertion block 310 will squeeze the polygonal block 142, causing the two polygonal blocks 142 to shrink back. When the insertion block 310 continues to descend until the polygonal slot 311 corresponds to the polygonal block 142, the return spring 144 that has lost pressure will push the polygonal block 142 into the polygonal slot 311, so that the two are clamped, increasing the tightness of the connection between the blade 300 and the support 120; when the blade 300 needs to be replaced, the handle 212 is turned counterclockwise so that the clamping block 1 220 and the clamping block 2 221 no longer clamp the blade 300, and the two pull rings 143 are pulled to make the two polygonal blocks 142 retract and no longer clamped with the polygonal slot 311. At this time, the blade 300 can be directly taken out for replacement.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention. Any reference sign in a claim should not be construed as limiting the claim to which it relates.

[0034] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
