[0015] A method for using a milling device for manufacturing a mold steel blank, using the milling device for manufacturing a mold steel blank, includes the following steps:

[0016] S1 First, fix the fixture on the workbench, and then place the steel blank on the fixture and fix it;

[0017] S2 Then, control the milling cutter to mill on the surface of the steel blank, and at the same time control the coolant in the cooling pipe to spray and cool the milling cutter and the steel blank. While the milling cutter is milling, the chips generated by the milling, under the blocking of the chip guard and the flushing of the coolant, automatically fall into the recovery tank through the gap between the support plates. At the same time, under the flushing of the water flow, it automatically enters the recovery box through the return hose, and then the metal chips pass through the filter screen, realizing the separation from the coolant, enabling the coolant to be recycled;

[0018] S3 When the milling is completed, control the separation of the support plate from the fixture, and then control the support plate to move downward automatically in the recovery tank. When the support plate moves above the spray pipe, control the support plate to rotate so that the spray liquid in the spray holes sprays out, which can automatically spray and flush the surface of the support plate, enabling the metal chips on the surface of the support plate to automatically fall into the recovery tank, realizing the automatic cleaning of the support plate. While the spray holes are flushing, the support plate can also be controlled to swing back and forth, making the flushing of the spray holes on the surface of the support plate more thorough. And after the flushing is completed, through the swinging of the support plate, the liquid and metal chips on the surface of the support plate can be separated more thoroughly.

[0019] Compared with the prior art, the present invention has the following technical effects:

[0020] The design of the chip guard can effectively prevent the metal chips from splashing everywhere when the milling cutter is milling, enabling the metal chips to be better concentrated on the workbench and fall into the recovery tank better, realizing the automatic recovery of the metal chips. The addition of the cooling pipe can better cool the milling area while the milling cutter is milling. At the same time, the spray volume of the cooling pipe can be controlled to increase, so that the sprayed coolant can not only cool down, but also the sprayed water column can effectively suppress the flying of the metal chips. The addition of the recovery box and the circulation pump can enable the coolant to be recycled, reducing costs.

[0021] The design of the support plate that can move up and down and rotate enables, after milling, through the downward movement of the support plate and in cooperation with rotation, the metal debris on the surface of the support plate to automatically fall into the recovery tank after rotation. At the same time, controlling the support plate to move downward above the spray pipe, in cooperation with the spraying of the spray holes and the rotation of the support plate, can make the impurities on the surface of the support plate be separated more thoroughly. And after the rinsing is completed, stopping the spraying of the spray holes, and through the rotational swing of the support plate, the coolant and metal debris on the surface of the support plate can be better separated, realizing the automatic cleaning of the metal debris on the surface of the support plate, thus making the overall cleaning work simpler after processing is completed.

A cooling pipe for spraying and cooling the milling cutter is provided inside the chip guard 11. A workbench 13 with adjustable position is provided below the milling cutter. A recovery groove 134 is provided on the workbench 13. A plurality of support plates 131 that can move up and down and rotate are provided in the recovery groove 134. A fixture 12 for clamping and fixing the steel blank is also provided on the workbench 13. The fixture 12 is detachably connected to the support plate 131. A plurality of spray pipes 133 are provided at the bottom of the recovery groove 134. Spray holes for flushing the surface of the support plate 131 are provided on the spray pipes 133. A recovery box 15 is provided below the workbench 13. A filter screen 151 is provided in the recovery box 15. A circulation pump 152 is provided in the recovery box 15 below the filter screen 151. The output end of the circulation pump 152 is respectively communicated with the cooling pipe and the spray pipe 133. The bottom of the recovery groove 134 is inclined, and a recovery hose is provided at the lowest point of the bottom of the recovery groove 134. The extended end of the recovery hose is communicated with the recovery box 15.

[0038] The design of the chip guard 11 can effectively prevent metal chips from splashing everywhere during milling, enabling the metal chips to be better concentrated on the workbench 13 and fall into the recovery groove 134 better, realizing the automatic recovery of metal chips. The addition of the cooling pipe enables the milling cutter to better cool the milling area while milling. At the same time, the spray volume of the cooling pipe can be controlled to increase, so that the sprayed coolant can not only cool down but also the sprayed water column can effectively suppress the flying of metal chips. The addition of the recovery box 15 and the circulation pump 152 enables the coolant to be recycled, reducing costs. The design of the support plate 131 that can move up and down and rotate enables, after milling is completed, through the downward movement and rotation of the support plate 131 in cooperation, the metal debris on the surface of the support plate 131 to automatically fall into the recovery groove 134 after rotation. At the same time, control the support plate 131 to move downward to above the spray pipe 133. With the spraying of the spray holes and the rotation of the support plate 131, the impurities on the surface of the support plate 131 can be separated more thoroughly. And after the flushing is completed, stop the spraying of the spray holes. Through the rotational swing of the support plate 131, the coolant and metal debris on the surface of the support plate 131 can be better separated, realizing the automatic cleaning of the metal debris on the surface of the support plate 131.

[0039] In this embodiment, please refer to Figure 2 、 Figure 3 and Figure 4, side wall grooves are provided on both side walls of the recovery tank 134, first adjusting plates 135 capable of moving up and down are provided in the side wall grooves, a plurality of adjusting grooves 1353 corresponding to the support plates 131 in number are provided on the first adjusting plates 135, the adjusting grooves 1353 are arc-shaped, the width of the inlet of the adjusting groove 1353 is the same as the width of the support plate 131, and positioning plates 1351 which are matched and rotatably connected are provided in the adjusting grooves 1353. Positioning grooves 1354 are provided on the positioning plates 1351. Both ends of the support plate 131 are fixedly connected to the corresponding positioning grooves 1354 respectively, and the upper surface of the support plate 131 is flush with the first adjusting plate 135. A first gear is fixedly connected to one side of each first adjusting plate 135. A plurality of first plates 136 are fixedly connected in the side wall grooves. First racks 1361 meshing with the corresponding first gears are provided on one side of each first plate 136.

[0040] The designs of the first adjusting plate 135, the positioning plate 1351 and the positioning groove 1354 can, through the fixed connection between the positioning plate 1351 and the support plate 131 and the rotational connection between the positioning plate 1351 and the adjusting groove 1353, realize the rotational design of the support plate 131 in the adjusting groove 1353. At the same time, the design that the surface of the support plate 131 is flush with the surface of the first adjusting plate 135 can, after the adjusting plate contacts the inner wall of the upper part of the side wall groove, better extrude and fix the support plate 131, ensuring the stability of the support plate 131 during fixation. The designs of the first gear and the first rack 1361 can, when the first adjusting plate 135 moves downward to the position of the first rack 1361, through the meshing transmission between the first gear and the first rack 1361, realize the automatic rotation of the support plate 131. By controlling the length of the first rack 1361, after the first gear passes through the first rack 1361, it can automatically rotate 180 degrees, realizing the automatic flipping of the support plate 131. At the same time, by controlling the friction coefficient between the adjusting groove 1353 and the positioning plate 1351, after the support plate 131 rotates, it no longer shakes, ensuring the stability during overall use.

[0041] In this embodiment, please refer to Figure 2 , Figure 3 , second adjusting plates 137 capable of reciprocating back and forth are provided in the side wall grooves. The end parts of the support plates 131 are located outside the first adjusting plates 135, and limiting grooves 1311 are provided at the end parts of the upper surfaces of the support plates 131. The limiting grooves 1311 are in a shape of an inverted V. Limiting plates 1371 which can be bent and are used for inserting into the limiting grooves 1311 are provided on the second adjusting plates 137.

[0042] The design of the second adjusting plate 137, the limiting plate 1371 and the limiting groove 1311 enables the support plate 131 to continue to move downward after flipping, so that the limiting plate 1371 is inserted into the limiting groove 1311. Since the limiting plate 1371 is a bendable plate, with the reciprocating movement of the second adjusting plate 137, by selecting a limiting plate 1371 with appropriate elasticity, during the movement of the second adjusting plate 137, the limiting plate 1371 can be used to squeeze the support plate 131 to deflect. And the reciprocating movement of the second adjusting plate 137 can realize the reciprocating swing of the support plate 131. In this way, the spray holes can wash the support plate 131 more thoroughly, improving the washing efficiency.

[0043] In this embodiment, please refer to Figure 3 , Figure 5 and Figure 6 , a driving mechanism for driving the second adjusting plate 137 to reciprocate is provided in the side wall groove below the first adjusting plate 135. The driving mechanism includes a fixing plate 138, a driving disk 1388 and a driving rod 1383. The fixing plate 138 is fixedly installed in the side wall groove. The driving disk 1388 is rotatably arranged on one side of the fixing plate 138. A limiting frame 1386 is fixedly connected to the same side of the fixing plate 138. The driving rod 1383 is slidably connected in the limiting frame 1386. One end of the driving rod 1383 is connected to the second adjusting plate 137, and a linkage rod 1387 is rotatably connected to the other end of the driving rod 1383. The extending end of the linkage rod 1387 is rotatably connected to one side of the driving disk 1388.

[0044] The design of the driving disk 1388, the driving rod 1383 and the linkage rod 1387 can realize the reciprocating movement of the driving rod 1383 by the rotation of the driving disk 1388, so that the second adjusting plate 137 can realize the reciprocating movement.

[0045] In this embodiment, please refer to Figure 3 , Figure 5 and Figure 6 , a driving shaft is rotatably connected to the fixing plate 138. The driving shaft is connected to the driving disk 1388. A second gear 1385 fixedly connected to the driving shaft is provided on the other side of the fixing plate 138. A top plate is fixedly connected to the fixing plate 138. A second plate 1381 is slidably connected to one side of the top plate. A second rack 1382 meshing with the second gear 1385 is provided on the second plate 1381. A first spring 1384 for driving the second plate 1381 to automatically return to the initial position is provided in the side wall groove.

[0046] The design of the second gear 1385, the second rack 1382, and the first spring 1384 enables the first adjusting plate 135, when moving downward to the second rack 1382, to press the second rack 1382 downward and compress the first spring 1384 to store energy. At the same time, the second rack 1382 drives the driving disk 1388 to rotate through meshing, so that the second adjusting plate 137 can reciprocate, control the length of the limiting plate 1371, and insert it into the limiting groove 1311 before the first adjusting plate 135 contacts the second plate 1381. In this way, when the second adjusting plate 137 reciprocates, the limiting plate 1371 can drive the support plate 131 to swing back and forth. In this way, during the downward movement of the support plate 131, it can swing back and forth. When the first adjusting plate 135 moves upward, the first spring 1384 can drive the second rack 1382 to move upward. At this time, the second gear 1385 can drive the driving disk 1388 to rotate synchronously, so that the second adjusting plate 137 reciprocates. In this way, no matter whether the support plate 131 moves upward or downward, the support plate 131 can automatically swing back and forth.

[0047] In this embodiment, please refer to Figure 5 , a plurality of reset grooves 1372 are provided on the second adjusting plate 137, the limiting plate 1371 is slidably connected in the reset grooves 1372, and a second spring 1373 for driving the limiting plate 1371 to automatically pop outwards is provided in the reset grooves 1372.

[0048] Since the support plate 131 needs to swing a certain number of times, if the second plate 1381 and the second rack 1382 are too short, the number of swings of the support plate 131 will be too small. If the number of swings of the support plate 131 is to be increased, the lengths of the second plate 1381 and the second rack 1382 need to be increased, which results in an excessive length of the limiting plate 1371. However, the length of the limiting groove 1311 is limited. Therefore, the second spring 1373 and the reset grooves 1372 can enable the limiting groove 1311 to automatically squeeze and recover the limiting plate 1371 into the reset grooves 1372 during the downward pressing process. When the limiting groove 1311 moves upward, the second spring 1373 can drive the limiting plate 1371 to move upward automatically, thereby ensuring that the limiting plate 1371 is always located in the limiting groove 1311 before complete separation, ensuring the stability of the swing of the support plate 131.

[0049] In this embodiment, refer to Figure 3 , a plurality of hydraulic rods 1352 are provided in the side wall groove, and the extending ends of the hydraulic rods 1352 are fixedly connected to the first adjusting plate 135.

[0050] In this embodiment, please refer to Figure 1, a longitudinally moving table 14 is fixedly connected to the device main body 1, a laterally moving table capable of reciprocating motion is provided on the longitudinally moving table 14, and the workbench 13 is arranged on the laterally moving table so as to be able to move back and forth laterally. Both the longitudinally moving table 14 and the laterally moving table are prior arts in the field of existing milling machines. Therefore, how the laterally moving table moves on the longitudinally moving table 14 and how the workbench 13 moves on the laterally moving table will not be elaborated too much in this application.

[0051] A method for using a milling device for manufacturing die steel blanks, using the milling device for manufacturing die steel blanks, includes the following steps:

[0052] S1 First, fix the fixture 12 on the workbench 13, and then place the steel blank on the fixture 12 and fix it;

[0053] S2 Then control the milling cutter to mill on the surface of the steel blank, and at the same time control the coolant in the cooling pipe to spray and cool the milling cutter and the steel blank. While the milling cutter is milling, the chips generated by the milling, under the blocking of the chip guard 11 and the flushing of the coolant, automatically fall into the recovery tank 134 through the gaps between the support plates 131, and at the same time, under the flushing of the water flow, automatically enter the recovery box 15 through the return hose 132, and then the metal chips pass through the filter screen 151 to realize the separation from the coolant, enabling the coolant to be recycled;

[0054] S3 After the milling is completed, control the support plate 131 to separate from the fixture 12, and then control the support plate 131 to move downward automatically in the recovery groove 134. When the support plate 131 moves above the spray pipe 133, control the hydraulic rod 1352 to retract, so that the first adjustment plate 135 moves downward automatically. When the first gear moves to the first rack 1361, through the meshing transmission of the gears, drive the support plate 131 to automatically flip 180 degrees, realizing the rotation of the support plate 131. At this time, make the spray liquid in the spray holes spray out. The spray liquid can automatically spray and wash the surface of the support plate 131, so that the metal chips on the surface of the support plate 131 can automatically fall into the recovery groove 134, realizing the automatic cleaning of the support plate 131. Then continue to control the hydraulic rod 1352 to contract. Before the bottom of the first adjustment plate 135 contacts the second plate 1381, the limit plate 1371 automatically inserts into the corresponding limit groove 1311. As the first adjustment plate 135 squeezes the second plate 1381, through the meshing transmission of the gears, drive the drive disk 1388 to rotate, making the second adjustment plate 137 reciprocate. In this way, while the spray holes are flushing, the support plate 131 can also be controlled to swing back and forth, making the spray holes flush the surface of the support plate 131 more thoroughly. When the first adjustment plate 135 moves to the bottommost position, control the hydraulic rod 1352 to drive the first adjustment plate 135 to rise, and at the same time control the spray liquid to stop spraying. At this time, the second plate 1381 moves upward automatically under the action of the first spring 1384, and control the rising speed, thereby driving the second adjustment plate 137 to reciprocate again, and the swinging speed is increased. In this way, the support plate 131 can separate the residual spray liquid and metal debris on the surface of the support plate 131 by swinging. After the flushing is completed, through the swinging of the support plate 131, the liquid and metal chips on the surface of the support plate 131 can also be separated more thoroughly;

[0055] After the first adjustment plate 135 separates from the second plate 1381, the second adjustment plate 137 stops moving. By controlling the number of teeth of the second gear 1385 and the second rack 1382, when the second adjustment plate 137 stops, the limit plate 1371 is located at the position in the initial state, so that the limit groove 1311 can be inserted more easily next time;

[0056] When the first adjusting plate 135 continues to move upward, the limiting plate 1371 is separated from the limiting groove 1311. When the first adjusting plate 135 moves to the first rack 1361, the first rack 1361 can automatically drive the support plate 131 to flip 180 degrees automatically, making the limiting groove 1311 face upward automatically. When the first adjusting plate 135 contacts the inner wall of the side wall groove, it can squeeze and fix the support plate 131 and the side wall groove. At the same time, a plurality of clamping rods can also be arranged on the inner wall of the side wall groove. In this way, when the support plate 131 contacts the side wall groove, the clamping rods are engaged with the limiting groove 1311. By this means, the support plate 131 can be more stable when fixed.
