[0004] The present invention aims at the technical problems existing in the prior art and provides a method for grooving bars for building material processing to solve the problem that the existing method for grooving bars for building material processing is not convenient for centering and clamping bars of different diameters and for loosening them when in use. At the same time, it is not convenient to control the clamping force, which affects the efficiency and quality of grooving. Moreover, when grooving, it is necessary to spray coolant through a cooling pipe for cooling and lubrication. However, this method is not convenient for concentrated spraying on the processing parts, which easily leads to waste of coolant. Moreover, it is not convenient to spray into the groove, which affects the cooling and lubrication effects and further affects the quality of grooving.

[0005] The technical solution of the present invention to solve the above technical problems is as follows: A method for cutting grooves in bars for building material processing, comprising the following steps: S1: Preset, prepare the double-head slot milling equipment; S2: Loading, placing the bars for building material processing on the double-headed slot milling equipment for clamping and fixing; S3: Grooving. After step S2, the double-headed milling equipment performs double-sided milling of the bars for building material processing to achieve the grooving operation. The double-head milling groove equipment includes a workbench and two movable seats, and the two movable seats are rotatably connected with milling cutters. The top of the workbench is connected with a U-shaped plate through a movable module, and two opposite side walls of the U-shaped plate are fixedly connected with a plurality of groups of symmetrically arranged telescopic sleeves, and the opposite ends of the telescopic sleeves are fixedly connected with two symmetrically arranged movable plates, and the opposite side walls of the two movable plates are connected with two symmetrically arranged V-shaped blocks through a first telescopic mechanism. The movement of the V-shaped blocks is driven by a first pushing mechanism, and the movement of the movable plates is driven by a second pushing mechanism. The side walls of each of the movable seats are provided with a spray mechanism for cooling and lubricating the grooving parts.

[0006] The beneficial effects of the present invention are: , by setting a first pushing mechanism and a second pushing mechanism, when it is necessary to cut a groove on the bar, first energize the electromagnet, and after energizing the electromagnet, the iron block is attracted, so that the upper V-shaped block moves upward, and at the same time, the first spring is compressed, and then the bar is placed on a V-shaped block below, and then the electromagnet is powered off. At this time, under the action of the first spring, the two V-shaped blocks can clamp the bar in the center, and then the two moving seats drive the two milling cutters to move closer to each other. At the same time, when the moving seat moves, the two mounting blocks are driven to move synchronously through the fixed plate and the connecting plate, and the pushing block is driven to move through the constant pressure mechanism. At the same time, the third spring is compressed. At this time, the pushing rod can slide upward in the inclined groove, thereby pushing the two moving plates to move closer to each other, so that the first spring continues to be compressed, and then the squeezing force of the two V-shaped blocks on the bar gradually increases. When the required extrusion pressure is reached, when the moving seat and the milling cutter continue to move, the moving rod can be pushed to move into the fixed tube. At the same time, under the action of the hydraulic oil, the counterweight plate is pushed to move upward along the working tube. When the milling cutter contacts the bar, the U-shaped plate is driven to move by the moving module, and then the bar is driven to move, so that the grooving operation of the bar can be realized, thereby ensuring that the clamping force of the V-shaped block on the bar is constant, and the clamping effect is ensured. After the grooving is completed, the two moving seats drive the two milling cutters to move away from each other, the pushing block can move and reset under the action of the third spring, and the moving plate can move and reset under the action of the first spring, and then, the electromagnet is energized to attract the iron block again, so that the upper V-shaped block moves upward, and the grooved bar can be released, thereby facilitating the automatic clamping and automatic release of bars of different diameters, which can improve the efficiency of grooving.

[0007] , by setting up a spray mechanism, etc., when grooving, when the ball abuts against the side wall of the rod, when the movable seat and the milling cutter continue to move, the second spring can be compressed, so that when grooving rods of different directions, the distance between the annular cover and the rod can be kept the same. Then, coolant is supplied into the annular cover through the oil supply hose and sprayed out through the spray hole, so that it is convenient to spray the grooving part and can be sprayed into the interior of the groove. At the same time, it can be ensured that the spraying part is always in the processing part, which can improve the cooling and lubrication effect while avoiding the waste of coolant. After the grooving is completed, when the movable seat and the milling cutter move to reset, the bristles can clean the debris on the surface of the milling cutter to ensure the quality of subsequent grooving.

When it is necessary to cut grooves on the rod, the electromagnet 602 is energized first. After the electromagnet 602 is energized, it attracts the iron block 601, so that the upper V-block 15 moves upward. At the same time, the first spring 503 is compressed, and then the rod is placed on a V-block 15 at the bottom.

When the movable seat 102 moves, the two mounting blocks 703 are driven to move synchronously through the fixed plate 701 and the connecting plate 702, and the pushing block 704 is driven to move through the constant pressure mechanism. At this time, the pushing rod 706 can slide upward in the inclined groove 705, thereby pushing the two movable plates 14 to move closer to each other, so that the first spring 503 continues to be compressed, and then the squeezing force of the two V-shaped blocks 15 on the rod is gradually increased.

[0040] In this embodiment, Figure 7 As shown, the constant pressure mechanism includes a fixed tube 801 fixedly connected to the side wall of the pushing block 704, and a moving rod 804 is inserted in the fixed tube 801, the other end of the moving rod 804 is connected to the side wall of the mounting block 703 through a sliding mechanism, and a working tube 802 is fixedly connected to the top of the fixed tube 801, the working tube 802 and the fixed tube 801 are filled with hydraulic oil, and a counterweight plate 803 is slidably connected in the working tube 802. After the required extrusion pressure is reached, when the moving seat 102 and the milling cutter 103 continue to move, the moving rod 804 can be pushed to move into the fixed tube 801. At the same time, under the action of the hydraulic oil, the counterweight plate 803 is pushed to move upward along the working tube 802. When the milling cutter 103 contacts the rod, the U-shaped plate 12 is driven to move by the moving module 11, and then the rod is driven to move, so that the grooving operation of the rod can be realized, thereby ensuring that the clamping force of the V-block 15 on the rod is constant, thereby ensuring the clamping effect.

[0041] In this embodiment, Figure 7As shown, the sliding mechanism includes a guide rail 1001 fixedly connected to the side wall of the mounting block 703, a slider 1002 is slidably connected to the guide rail 1001, and the slider 1002 is fixed to the other end of the moving rod 804.

[0042] The specific method of use of the present invention is as follows: When in use, first, when it is necessary to cut a groove on the bar, the electromagnet 602 is energized, and the electromagnet 602 attracts the iron block 601 after being energized, so that the upper V-shaped block 15 moves upward, and at the same time, the first spring 503 is compressed, and then the bar is placed on a V-shaped block 15 below, and then the electromagnet 602 is powered off. At this time, under the action of the first spring 503, the two V-shaped blocks 15 can clamp the bar in the middle, and then the two moving seats 102 drive the two milling cutters 1 03 move closer to each other. At the same time, when the moving seat 102 moves, the two mounting blocks 703 are driven to move synchronously through the fixed plate 701 and the connecting plate 702, and the push block 704 is driven to move through the constant pressure mechanism. At the same time, the third spring 904 is compressed. At this time, the push rod 706 can slide upward in the inclined groove 705, thereby pushing the two moving plates 14 to move closer to each other, so that the first spring 503 continues to be compressed, and then the extrusion force of the two V-shaped blocks 15 on the rod is gradually increased; After the required extrusion pressure is reached, when the moving seat 102 and the milling cutter 103 continue to move, the moving rod 804 can be pushed to move into the fixed tube 801. At the same time, under the action of the hydraulic oil, the counterweight plate 803 is pushed to move upward along the working tube 802. When the milling cutter 103 contacts the bar, the U-shaped plate 12 is driven to move by the moving module 11, and then the bar is driven to move, so that the grooving operation of the bar can be realized, thereby ensuring that the clamping force of the V-block 15 on the bar is constant, ensuring the clamping effect. After the grooving is completed, the two moving seats 102 drive the two milling cutters 103 to move away from each other, the push block 704 can be moved and reset under the action of the third spring 904, and the moving plate 14 can be moved and reset under the action of the first spring 503. Then, the electromagnet 602 is energized to attract the iron block 601 again, so that the upper V-shaped block 15 moves upward, and the grooved bar can be released, so that the bars with different diameters can be automatically clamped and released, which can improve the efficiency of grooving. When grooving, when the ball 402 abuts against the side wall of the rod, when the movable seat 102 and the milling cutter 103 continue to move, the second spring 304 can be compressed, so that when grooving rods of different directions, the distance between the annular cover 201 and the rod can be kept the same. Then, coolant is supplied into the annular cover 201 through the oil supply hose 204 and sprayed out through the spray hole 203, so as to facilitate the spraying of the grooving part and the spraying into the interior of the groove. At the same time, it can be ensured that the spraying part is always in the processing part, which can improve the cooling and lubrication effect while avoiding the waste of coolant. After the grooving is completed, when the movable seat 102 and the milling cutter 103 move to reset, the bristles 202 can clean the debris on the surface of the milling cutter 103 to ensure the quality of subsequent grooving.

[0043] In summary: the beneficial effects of the present invention are specifically embodied in that it is convenient to automatically clamp and loosen rods of different diameters; it can ensure that the clamping force of the V-block 15 on the rod is constant; it can ensure that the distance between the annular cover 201 and the rod is the same, and spray out through the spray hole 203, so as to facilitate the spraying of the grooving part and the spraying into the interior of the groove. At the same time, it can ensure that the spraying part is always in the processing part, which can improve the cooling and lubrication effect while avoiding the waste of coolant, thereby improving the efficiency and quality of grooving.
