Description

Technical Field

[0001] This application relates to the technical field of metal processing, and in particular to a drilling apparatus for processing metal products. Background Technology

[0002] Drilling equipment is frequently used in the production and processing of metal products. The purpose is to alter the shape, size, properties, or surface characteristics of metal products to meet specific requirements.

[0003] For example, Chinese utility model patent CN221065543U discloses a drilling device for metal processing, including a processing table. A U-shaped frame is fixedly connected to the upper part of the processing table, and multiple electric push rods are fixedly installed on the U-shaped frame. The bottom ends of two electric push rods are fixedly connected to the same mounting plate. A motor is fixedly installed on the upper part of the mounting plate, and a drill bit is rotatably connected to the bottom end of the mounting plate. The output shaft of the motor is connected to the top end of the drill bit. A connecting sleeve is provided at the bottom end of the mounting plate, and the drill bit is located inside the connecting sleeve. A groove is opened inside the connecting sleeve, and a protective mechanism is provided in the groove. L-shaped plates are fixedly connected to the upper left and right sides of the processing table. When this utility model is used, it can not only effectively prevent the flying of chips generated during drilling when drilling metal products, but also does not reduce the drilling efficiency of metal products, while greatly improving the protection of the drill bit.

[0004] Regarding the aforementioned technologies, the inventors believe that when using this device, the threaded rod drives the fixing block to move down to clamp and fix the metal product. Then, the drill bit can be used to drill holes in the metal product. However, when drilling holes in other positions of the metal product is required, the metal product needs to be removed, then the position changed, and then it needs to be fixed again. The operation is relatively cumbersome and has certain limitations in use. Utility Model Content

[0021] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0022] This application discloses a drilling apparatus for processing metal products. (Refer to...) Figure 1-3 A drilling device for processing metal products, comprising a base 1;

[0023] The upper surface of the base 1 is symmetrically provided with movable grooves 10 along the Y-axis. Multiple lower rotating shafts 16 are rotatably installed at equal intervals inside the movable grooves 10. Lower support rollers 11 are fixedly fitted on the side walls of the multiple lower rotating shafts 16 for supporting metal products.

[0024] A fixed frame 2 along the X-axis is symmetrically fixedly installed on the upper surface of the base 1. A synchronous electric actuator 3 is symmetrically fixedly installed on the upper surface of the two fixed frames 2. The output ends of the corresponding two synchronous electric actuators 3 are jointly fixedly installed with a transmission box 6 located above the base 1.

[0025] Both transmission boxes 6 have open lower surfaces. Multiple upper rotating shafts 18 are rotatably mounted at equal intervals on the inner sidewall of the transmission box 6. Upper pressure rollers 17 that cooperate with the lower support rollers 11 are fixedly fitted on the sidewalls of the multiple upper rotating shafts 18. The transmission box 6 is provided with a drive mechanism for driving the multiple upper pressure rollers 17 to rotate synchronously. The drive mechanism includes a synchronous motor 7, a connecting shaft 15, multiple worm gears 12 and multiple worms 14. Mounting plates 8 are symmetrically fixedly mounted on opposite sides of the two transmission boxes 6. A connecting shaft 15 is rotatably mounted between the corresponding two mounting plates 8. Multiple worms 14 are fixedly fitted at equal intervals on the sidewall of the connecting shaft 15. The synchronous motor 7 is fixedly connected to one side of one of the mounting plates 8. The output end of the synchronous motor 7 is fixedly connected to one end of the connecting shaft 15. One end of each of the multiple upper rotating shafts 18 movably passes through the sidewall of the transmission box 6 and is fixedly fitted with a worm gear 12 that meshes with the worm 14.

[0026] A bracket 4 is fixedly installed in the middle of the upper surface of the base 1. A drilling mechanism 5 is provided on the bracket 4 for drilling metal products.

[0027] Support legs 9 are fixedly installed at all four corners of the lower surface of the base 1;

[0028] A controller 13 is fixedly installed on one side of the bracket 4, which is electrically connected to the synchronous electric push rod 3, the synchronous motor 7 and the drilling mechanism 5 respectively, so as to realize intelligent control of the equipment.

[0029] The implementation principle of a drilling device for metal product processing according to an embodiment of this application is as follows: All electrical components in this application are externally connected to a power supply and control switch during use. During use, the base 1 provides stable support for the entire device, the support legs 9 on its lower surface ensure the device is placed flat, and the movable groove 10 on its upper surface provides installation space for the lower support rollers 11, forming the basic carrier for workpiece transport. Before processing, parameters are set according to the thickness of the metal product to be drilled via the controller 13 on one side of the bracket 4: the extension stroke of the synchronous electric push rod 3 and the rotational speed of the synchronous motor 7. After starting the device, the metal product (such as a steel plate or aluminum alloy profile) is placed between the lower support rollers 11 on the upper surface of the base 1. The lower support rollers 11 provide initial support and guidance for the workpiece through their own rotation. The controller 13 synchronously starts the synchronous electric push rods 3 on both sides. The output end of the synchronous electric push rods 3 drives the transmission box 6 to move vertically downwards until the upper pressure roller 17 inside the transmission box 6 contacts the upper surface of the workpiece. The upper pressure roller 17 and the lower support roller 11 form a coordinated constraint, fixing the workpiece with flexible clamping force. This prevents the workpiece from shifting during conveying and drilling, and also prevents workpiece deformation due to excessive tightness. Subsequently, the drive mechanism drives the upper pressure roller 17 to rotate synchronously: the output end of the synchronous motor 7 drives the connecting shaft 15 to rotate, and multiple worm gears 14 on the side wall of the connecting shaft 15 rotate synchronously. The worm gears 14 mesh with the worm wheel 12 at the end of the upper rotating shaft 18, transmitting the rotational power to the upper rotating shaft 18, which in turn drives the upper pressure roller 17 to rotate. The rotation of the upper pressure roller 17 generates a horizontal traction force, which, together with the driven rotation of the lower support roller 11, drives the metal product to be smoothly conveyed along the Y-axis, providing a continuous and stable processing reference for the drilling mechanism 5. When the metal product is conveyed to the support 4 in the middle of the base 1, the drilling mechanism 5 on the support 4 starts (the drilling mechanism 5 can be set with parameters such as drilling depth and speed according to requirements), and drills holes at designated positions on the workpiece. If multiple holes need to be processed, the device can automatically complete continuous drilling by simply presetting the hole spacing through the controller 13. After drilling is completed, the workpiece continues to be conveyed to the output end of the device along with the upper pressure roller 17 and the lower support roller 11, realizing the full automation of the "feeding-clamping-conveying-drilling-discharging" process.

[0030] During this process, the coordinated conveying design of the upper pressure roller 17 and the lower support roller 11 enables continuous automated conveying of metal products, significantly improving processing efficiency and adapting to large-scale production. The flexible clamping controlled by the synchronous electric push rod 3 can automatically adjust the height of the upper pressure roller 17 according to the workpiece thickness. The clamping and conveying work together to ensure processing accuracy. The controller 13 realizes the linkage control of the synchronous electric push rod 3, the synchronous motor 7 and the drilling mechanism 5, making operation convenient and intelligent. At the same time, the overall structure is relatively simple and easy to use, improving the practicality of the device.

[0031] Here, when the lead angle (λ) of the worm 14 is less than the friction angle (φ) of the contact surface between the worm wheel 12 and the worm 14, the transmission system of the worm wheel 12 and the worm 14 can achieve self-locking. Through an external power device, the worm 14 can be driven to rotate clockwise and counterclockwise, thereby realizing the clockwise and counterclockwise rotation of the worm wheel 12. The models of the electrical components and the drilling mechanism 5 involved in this application can be optimized according to actual conditions. These are existing technologies and widely used in society, so further details are omitted.
