[0010] Preferably, the fastening mechanism includes a fixing plate, two fixing plates are fixedly installed on the outer wall of the sliding plate along the axial direction, and a drive motor is embedded in the outer wall of one fixing plate. The power output end of the drive motor is connected to a bidirectional threaded rod, and a connecting rod is connected in the middle of the two bidirectional threaded rods. Two clamping plates are slidably connected to the outer wall of each bidirectional threaded rod, and mounting blocks are detachably installed at corresponding positions on the outer walls of the two clamping plates by bolts.

[0011] Preferably, the fastening mechanism further includes a collar, which is fixedly installed on the top of the outer wall of the sliding plate in the lower axial direction, and a support block is fixedly installed on the outer wall of the sliding plate at the position where the reserved groove is opened, and the top of the support block is evenly provided with limit grooves.

[0012] Preferably, the clamping plate is threadedly connected to the bidirectional threaded rod, and the clamping plate forms a sliding structure with the bidirectional threaded rod through the drive motor.

[0013] Preferably, the conveying mechanism includes a water tank, which is fixedly installed at the bottom of the assembly shell, and a pump is fixedly installed on one side inside the water tank. The output and input ends of the pump are both connected to conveying pipes, and the axial end of the conveying pipe extending out of the water tank is connected to a conveying head. A filter plate is slidably connected inside the water tank at a position corresponding to the bottom of the assembly shell.

[0014] Preferably, the water tank is connected to the conveying head of the conveying pipe, and the water tank is connected to the assembly shell.

[0016] Preferably, the connecting rod forms a rotating structure with the water tank and the loading shell through rotating sleeves at the top and bottom ends, respectively, and the rotating sleeve at the top end is threadedly connected to the sleeve block.

[0017] As can be seen from the above description, the technical solution described in this application can certainly solve the technical problem that this application aims to address.

[0018] Meanwhile, through the above technical solutions, the present invention has at least the following beneficial effects:

[0019] This invention utilizes a winding device to retract and extend a cable, allowing the electromagnet, threadedly connected to the connector, to pass through the rod. When the hydraulic rod drives the tilting block to bend the rod, the electromagnet's support enhances the load-bearing capacity, preventing excessive bending that could deform the rod and affect product quality. The threaded connection between the electromagnet and the connector facilitates disassembly and assembly, allowing for the replacement of electromagnets with diameters compatible with the rod, thus improving applicability. The cable energizes the electromagnet, facilitating the attraction of the rod and preventing slippage that could affect bending quality. When the electromagnet is not in operation, the winding device tightens the connector within the connection hole, facilitating the placement of the rod and its alignment with the electromagnet.

[0020] This invention uses a drive motor to rotate a bidirectional threaded rod, which in turn drives another set of bidirectional threaded rods to rotate via a connecting rod. This causes each set of bidirectional threaded rods to slide relative to its corresponding clamping plate, allowing the clamping plate to clamp and fix the rod with the mounting block. The invention features two sets of drive motors and bidirectional threaded rods to prevent rotation of the clamping plate caused by a single drive. The two sets of power also improve the stability and uniformity of the clamping, preventing wobbling or displacement during bending or grinding, which could lead to damage or deformation. The clamping plate is detachably mounted with bolts, and the mounting block, with its diameter adapted to the rod, enhances flexibility. The collar and electromagnet positions are vertically aligned, facilitating the determination and initial positioning of the rod. A limiting groove in the support block further limits the bending of one end of the rod, preventing wobbling during bending and further avoiding deformation.

[0021] After the punch body of the present invention is placed into the rotating sleeve, the cover and threaded connection sleeve block are closed and driven by the pressing block to press the punch body for fixation, so as to avoid the displacement during grinding and punching, which would cause uneven wall thickness and affect bending and deformation. It is fixed between the two sets of rotating sleeves by the connecting rod. Under the drive of the rotating motor, the worm gear drives the worm wheel, which in turn drives the connecting rod to rotate, so that the two sets of rotating sleeves can maintain stable rotation under the limit of the water tank and the loading shell. The delivery pipe passes through the connecting rod and the rotating sleeve without being fixed, and passes into the interior of the punch body. The punch body has a through hole to facilitate the flow of coolant from the grinding end to avoid overheating and damage. A sealing shell is provided at the grinding point of the punch body and the rod to prevent debris or coolant from splashing, and at the same time facilitates the return flow to the water tank, and prevents debris from adhering to the outer wall of the rod and causing texture during bending.

[0030] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0031] As attached Figures 1-5 As shown, the present invention provides a technical solution: a deep drilling device for a bent rod, comprising an assembly shell 1, a hydraulic cylinder 2 embedded at the top of the assembly shell 1, a pressing mechanism 3 connected to the power output end of the hydraulic cylinder 2, a sliding groove 5 formed on the mating surface of the assembly shell 1 and the pressing mechanism 3, a reserved groove 4 formed on the axial surface of the pressing mechanism 3 corresponding to the sliding groove 5, a fastening mechanism 6 axially installed below the pressing mechanism 3, a conveying mechanism 7 provided below the assembly shell 1, a sealing shell 8 provided at the front end of the assembly shell 1 at the bottom end of the pressing mechanism 3, and a sealing shell 8 on one side above the conveying mechanism 7. A grinding mechanism 9 is installed at the position corresponding to the pressing mechanism 3. Baffles 11 are fixed on both sides of the outer wall of the assembly shell 1. A structural frame 10 is fixed on the side of the two baffles 11 at the front end of the sealing shell 8. The pressing mechanism 3 is pushed by the hydraulic cylinder 2 to slide along the slide groove 5 on the assembly shell 1, thereby driving the rod held by the fastening mechanism 6 to move towards the grinding mechanism 9 and be ground by the grinding mechanism 9. Coolant is delivered through the conveying mechanism 7 to avoid damage caused by overheating during grinding. After grinding is completed, the pressing mechanism 3 is reset, and the rod is bent by the operation of the internal components of the pressing mechanism 3.

[0032] The pressing mechanism 3 includes a sliding plate 301, which is slidably connected to the inside of the slide groove 5. An mounting shell 302 is fixed axially to the outside of the sliding plate 301. The main body 303 of the winding device is embedded inside the mounting shell 302. A connecting hole 304 is provided at the bottom of the mounting shell 302, through which a connector 305 extends. An electromagnet 306 is fitted onto one end of the connector 305 extending through the connecting hole 304. A hydraulic rod 307 is embedded at the top of the sliding plate 301, and an inclined block 308 is connected to the power output end of the hydraulic rod 307. The inside of the slide groove 5 is slidably connected to the lower telescopic plate 309 of the sliding plate 301. The sliding plate 301 has a U-shaped structure, and the sliding plate 301 forms a sliding structure with the mounting shell 1 via the slide groove 5. The main body 303 of the winding equipment winds up and unwinds the cable, allowing the electromagnet 306, threadedly connected to the connector 305, to pass into the rod. When the hydraulic rod 307 drives the tilting block 308 to bend the rod, the electromagnet 306 provides support to increase the load-bearing capacity, thus preventing excessive bending that could deform the rod and affect the product quality. The threaded connection between the electromagnet 306 and the connector 305 facilitates disassembly and assembly, allowing for the replacement of electromagnets 306 with diameters compatible with the rod, improving applicability. When the electromagnet 306 is energized via the cable, it attracts the rod, preventing slippage that could affect the bending quality. When the electromagnet 306 is not in operation, the main body 303 of the winding equipment tightens the connector 305 into the connection hole 304, facilitating the placement of the rod and its alignment with the electromagnet 306.

[0033] like Figure 1 , Figure 5 and Figure 7As shown, further, the fastening mechanism 6 includes a fixing plate 601. Two fixing plates 601 are fixedly installed on the outer wall of the sliding plate 301 along the axial direction. A drive motor 602 is embedded in the outer wall of one fixing plate 601. The power output end of the drive motor 602 is connected to a bidirectional threaded rod 603. A connecting rod 604 is connected between the two bidirectional threaded rods 603. Two clamping plates 605 are slidably connected to the outer wall of each bidirectional threaded rod 603. Mounting blocks 606 are detachably installed at corresponding positions on the outer walls of the two clamping plates 605 by bolts. The fastening mechanism 6 also includes a collar 607. The collar 607 is fixedly installed on the top of the outer wall of the sliding plate 301 along the lower axial direction. A support block 608 is fixedly installed on the outer wall of the sliding plate 301 at the position where the reserved groove 4 is opened. Limiting grooves 609 are evenly spaced at the top of the support block 608. The clamping plate 605 is threadedly connected to the bidirectional threaded rod 603. The clamping plate 605 forms a sliding structure with the bidirectional threaded rod 603 through the drive motor 602. Motor 602 drives bidirectional threaded rod 603 to rotate. The bidirectional threaded rod 603 drives another set of bidirectional threaded rods 603 to rotate through connecting rod 604. This causes each set of bidirectional threaded rods 603 to drive the corresponding clamping plate 605 to slide relative to each other. The clamping plate 605 drives the mounting block 606 to clamp and fix the rod. There are two sets of drive motors 602 and bidirectional threaded rods 603 to avoid the clamping plate 605 from rotating due to a single drive. At the same time, the two sets of power improve the stability and uniformity of clamping, and prevent shaking or displacement during bending or grinding, which could lead to damage or deformation. The clamping plate 605 is detachably installed with bolts and the mounting block 606 with a diameter adapted to the rod improves flexibility. The position of the collar 607 and the position of the electromagnet 306 are in a vertically corresponding position, which facilitates the determination and initial limitation of the rod position. The limiting groove 609 opened in the support block 608 facilitates the limitation of one end of the bent rod, preventing shaking during the bending process and further preventing deformation.

[0034] like Figure 1 , Figure 5 and Figure 7As shown, in a preferred embodiment, based on the above method, the conveying mechanism 7 further includes a water tank 701, which is fixedly installed at the bottom of the assembly shell 1. A pump 702 is fixedly installed on one side inside the water tank 701. Both the output and input ends of the pump 702 are connected to a conveying pipe 703. The axial end of the conveying pipe 703 extending out of the water tank 701 is connected to a conveying head 704. A filter plate 705 is slidably connected inside the water tank 701 at a position corresponding to the bottom of the assembly shell 1. The water tank 701 communicates with the assembly shell 1 through the conveying pipe 703 and the conveying head 704. The grinding mechanism 9 includes a loading... The housing 908 is fixed to the inner wall of the water tank 701 and located above the pump 702. A rotating motor 909 is embedded inside one side of the housing 908. A worm gear 907 is connected to the power output end of the rotating motor 909. A worm wheel 906 is connected to one side of the outer wall of the worm gear 907. A connecting rod 904 extends through the inside of the worm wheel 906. Rotating sleeves 905 are fixedly installed at both the top and bottom of the connecting rod 904. A punch body 901 extends through the rotating sleeve 905 at the top of the connecting rod 904. A fitting block 902 is fitted onto the outside of the rotating sleeve 905 at the top of the connecting rod 904. The inner wall of the fitting block 902 is flush with the punch. A pressing block 903 is fixedly installed at the axial fitting point of the main body 901. The connecting rod 904 forms a rotating structure with the water tank 701 and the loading shell 908 respectively through the rotating sleeves 905 at the top and bottom ends. The top rotating sleeve 905 is threadedly connected to the sleeve block 902. After the punch body 901 is inserted into the rotating sleeve 905, the cover is closed and the threaded connection sleeve block 902 is engaged, which drives the pressing block 903 to press the punch body 901 for fixation. This prevents displacement during grinding and punching, which could lead to uneven wall thickness and affect bending, causing deformation. It is fixed between the two sets of rotating sleeves 905 by the connecting rod 904. Driven by the rotating motor 909 The worm gear 907 drives the worm wheel 906, which in turn drives the connecting rod 904 to rotate. This allows the two sets of rotating sleeves 905 to maintain stable rotation under the constraints of the water tank 701 and the loading shell 908. The conveying pipe 703 passes through the connecting rod 904 and the rotating sleeve 905 without being fixed, and also penetrates into the interior of the punch body 901. The punch body 901 has a through hole inside to facilitate the flow of coolant from the grinding end to avoid overheating and damage. A sealing shell 8 is provided at the grinding point of the punch body 901 and the rod to prevent debris or coolant from splashing, and at the same time to facilitate the return flow to the water tank 701, preventing debris from adhering to the outer wall of the rod and causing texture when bending.

[0035] In summary:

[0036] This invention addresses the technical problem of drilling holes at the bottom of bent rods using a vertical lathe from bottom to top in existing technologies. However, this causes deformation of the outer wall of the bent rod during the bending process, affecting the quality of the finished product. The invention employs the technical solutions described in the above embodiments. Furthermore, the implementation process of the above technical solutions is as follows:

[0037] The fixed plate 601 of the fastening mechanism 6 is axially fixed by the sliding plate 301. The drive motor 602 embedded in the outer wall of the fixed plate 601 works to drive the bidirectional threaded rod 603 to rotate. The bidirectional threaded rod 603 passes through a set of two clamping plates 605 and is connected to another bidirectional threaded rod 603 via the connecting rod 604. At the same time, it passes through a set of two clamping plates 605. The end away from the drive motor 602 is fitted with a bearing and bolted to another set of fixed plates 601. This allows the drive motor 602 to work and make the two sets of clamping plates 605 move relative to each other. This makes it easier to drive the mounting block 606 to clamp the rod that passes through the collar 607. The clamping plate 605 is bolted to the mounting block 606 that is adapted to the diameter of the rod, thereby clamping and fixing the rod and preventing it from shaking and deforming during bending.

[0038] After the installation shell 302 is installed in the main body 303 of the winding equipment, the cable is wound up and unwound. The cable passes through the connecting hole 304 and connects to the connector 305. The connector 305 is threadedly connected to the electromagnet 306. The diameter of the electromagnet 306 is changed according to the diameter of the rod. Electrode points are provided at the connection point to facilitate the electromagnetic attraction of the electromagnet 306 after it is inserted into the rod, preventing the electromagnet 306 from slipping and misaligning, which would affect the bending. At the same time, the hydraulic rod 307 works to push the tilting block 308 down and to straighten the rod. The bending process, along with the winding equipment body 303, controls the winding and unwinding of the cable. The insertion point of the electromagnet 306 is controlled at the bending point of the rod, and it bends along with the bending end of the rod. The electromagnet 306 provides internal support to prevent internal deformation of the rod. The sliding plate 301 has a reserved groove 4 to prevent mutual restriction between the sliding plate 301 and the bending process. At the bending point of the rod, a support block 608 is fixed on one side of the reserved groove 4, and a limit groove 609 is embedded to limit the rod during the bending process and prevent it from shaking and deforming.

[0039] The sliding plate 301 of the pressing mechanism 3 is pushed by the hydraulic cylinder 2 and slides along the slide groove 5 on the assembly shell 1, thereby causing the sliding plate 301 to drive the clamped rod to slide down. At the same time, the connector 305 passes through the connecting hole 304, and the electromagnet 306 passes through the rod. The top of the rod resists the bottom of the mounting shell 302, and the bottom of the rod is located on the punch body 901 of the grinding mechanism 9. The pump 702 in the water tank 701 of the conveying mechanism 7 works to facilitate the delivery of coolant to the conveying head 704 through the conveying pipe 703, so as to achieve a cooling effect during grinding. The loading shell 908 is fixed inside the water tank 701. The top and bottom of the connecting rod 904 are fixed with rotating sleeves 905, which are rotatably connected to the water tank 701 and the loading shell 908 respectively. At the same time, the punch body 905... 1. The bottom end of the rotating sleeve 905 is inserted into the water tank 701 and sleeved on the outside of the conveying head 704 that protrudes from the rotating sleeve 905. At the same time, the upper rotating sleeve 905 is threadedly connected to the sleeve block 902. Simultaneously, the pressing block 903 presses the punch body 901 to ensure stable installation of the punch body 901 and prevents shaking during the grinding process, which would cause uneven wall thickness of the grinding rod and uneven stress and deformation during bending. At the same time, the rotating motor 909 embedded in the loading shell 908 works to drive the worm 907 to rotate, which in turn drives the worm wheel 906 to rotate. The worm wheel 906 drives the connecting rod 904 to rotate. The connecting rod 904, supported by the two sets of rotating sleeves 905, drives the punch body 901 to rotate, thereby punching the rod.

[0040] A sealing shell 8 is provided at the contact point between the bottom rod of the sliding plate 301 and the punch body 901. The sealing shell 8 is connected to the assembly shell 1 and its bottom is inclined, so that the coolant and debris can be flushed into the sealing shell 8 and flow back to the water tank 701. After being filtered by the filter plate 705 slidably connected to the water tank 701, the debris is recycled. The bottom of the sealing shell 8 is fixed with a telescopic plate 309. When the sliding plate 301 slides along the slide groove 5 on the assembly shell 1, multiple telescopic plates 309 are stacked and stretched to maintain the semi-enclosed nature of the assembly shell 1 and prevent the coolant from splashing out. The baffles 11 are fixed on both sides of the assembly shell 1 and the structural frame 10 is fixed in front of the grinding mechanism 9. The structural frame 10 is fitted with a tempered glass plate. While the sealing shell 8 seals to prevent debris from splashing during grinding, the structural frame 10 and the glass plate provide further protection to prevent the splashed debris from being difficult to clean or injuring others.

[0041] With the above-mentioned settings, this application will certainly solve the above-mentioned technical problems, and at the same time achieve the following technical effects:

[0042] This invention uses a drive motor 602 to rotate a bidirectional threaded rod 603. The bidirectional threaded rod 603, via a connecting rod 604, drives another set of bidirectional threaded rods 603 to rotate. This causes each set of bidirectional threaded rods 603 to slide relative to its corresponding clamping plate 605, allowing the clamping plate 605 to clamp and fix the rod to the mounting block 606. The invention provides two sets of drive motors 602 and bidirectional threaded rods 603 to prevent rotation of the clamping plate 605 caused by a single drive, and the dual power sources improve clamping stability and... Uniformity is ensured to prevent shaking or displacement during bending or grinding, which could lead to damage or deformation. The clamping plate 605 is detachably installed with bolts, and the mounting block 606 with a diameter adapted to the rod improves flexibility. The position of the collar 607 and the position of the electromagnet 306 are vertically aligned, which facilitates the determination and initial positioning of the rod. The limiting groove 609 opened in the support block 608 facilitates the limiting of one end of the bent rod, preventing shaking during the bending process and further preventing deformation.

[0043] After the punch body 901 of the present invention is inserted into the rotating sleeve 905, the cover and threaded connection sleeve block 902 are closed and driven by the pressing block 903 to press the punch body 901 for fixation, so as to avoid displacement during grinding and punching, which would cause uneven wall thickness and affect bending and deformation. It is fixed between the two sets of rotating sleeves 905 by the connecting rod 904. Under the drive of the rotating motor 909, the worm 907 drives the worm wheel 906, which in turn drives the connecting rod 904 to rotate, so that the two sets of rotating sleeves 905 are in the water tank. The 701 and the loading shell 908 maintain stable rotation under the limiting position. The conveying pipe 703 passes through the connecting rod 904 and the rotating sleeve 905 and is not fixed. It also passes into the interior of the punch body 901. The punch body 901 has a through hole to facilitate the flow of coolant from the grinding end to avoid overheating and damage. A sealing shell 8 is provided at the grinding point of the punch body 901 and the rod to prevent debris or coolant from splashing. At the same time, it facilitates the return flow to the water tank 701 and prevents debris from adhering to the outer wall of the rod, which would cause texture when bending.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
