[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0015] The forklift processing crossbeam punching device provided by this utility model includes a base 1. The base 1 is fixedly mounted with a slide rail 2, a translation motor 3, and symmetrically arranged translation cylinders 4. The slide rail 2 is movably mounted with a main moving platform 5 and symmetrically arranged auxiliary moving platforms 6. The translation motor 3 is driven and connected to the main moving platform 5 via a lead screw 7, and the translation cylinders 4 are driven and connected to the auxiliary moving platforms 6. The main moving platform 5 is fixedly mounted with a punching assembly 8. The auxiliary moving platform 6 is fixedly mounted with a rotary motor 9 and a support plate 10. The support plate 10 is movably mounted with a rotating disk 11, and a gear ring 12 is fixedly mounted on the rotating disk 11. The rotary motor 9 is connected to the gear ring 12 via a gear 13. The rotating disk 11 has a placement opening 14, and four clamping cylinders 15 are fixedly mounted on the rotating disk 11 around the placement opening 14. A collection box 16 is fixedly mounted on the main moving platform 5. Protective shells 17 are provided on the outer sides of both the translation motor 3 and the rotary motor 9. The rotating disk 11 is made of iron.

[0016] Through the above technical solution, the base 1 of this utility model is movably mounted with a main moving stage 5 and symmetrically arranged auxiliary moving stages 6 via a slide rail 2. The translation motor 3 drives the main moving stage 5 through a lead screw 7, which facilitates the adjustment of the position of the punching assembly 8 and precisely controls the punching position of the crossbeam. The translation cylinder 4 drives the auxiliary moving stage 6 to start, and together with the clamping cylinder 15 set around the placement opening 14 on the rotating disk 11, the two ends of the crossbeam are fixed. During punching, the two ends of the crossbeam to be processed are aligned with the height of the placement opening 14. The translation cylinder 4 drives the auxiliary moving stage 6 to move, so that the two ends of the crossbeam to be processed enter the placement opening 14. The position of the crossbeam is adjusted, and the clamping cylinder 15 is activated to clamp and fix the two ends of the crossbeam to be processed. The translation motor 3 drives the main moving stage 5 through the lead screw 7 to control the punching assembly 8 to move to the punching position of the crossbeam and quickly complete the punching. When it is necessary to switch the processing surface of the crossbeam to be processed, the rotary motor 9 drives the rotating disk 11 to rotate, quickly so that the processing surface of the crossbeam to be processed is aligned with the punching assembly 8, thereby improving processing efficiency. Example

[0017] This implementation mainly consists of a base 1, a slide rail system 2, a moving stage assembly, and a punching actuator. The base 1 serves as the supporting foundation for the entire device, with a linear slide rail 2 fixedly mounted on its upper part. This slide rail 2 employs a high-precision ball bearing guide structure to ensure smooth operation of the moving parts. Translation cylinders 4 are symmetrically arranged on both sides of the base 1, and the cylinder piston rods are rigidly connected to the auxiliary moving stage 6 via connecting parts. A precision ball screw 7 driven by a servo motor is installed in the middle of the base 1, and the nut of the screw 7 is fixedly connected to the main moving stage 5, achieving precise position control of the main moving stage 5.

[0018] The main moving table 5 is equipped with a punching assembly 8, which includes a hydraulically driven punch and a matching die. The punch is replaceable, allowing for the selection of punches with different hole diameters according to processing requirements. A slider that mates with the slide rail 2 is located at the bottom of the main moving table 5, ensuring stability and accuracy during movement. The translation motor 3 is connected to the lead screw 7 via a coupling; when the motor rotates, it drives the main moving table 5 to move linearly along the slide rail 2, achieving precise adjustment of the punching position.

[0019] Two auxiliary moving platforms 6 are symmetrically arranged on both sides of the main moving platform 5, and each auxiliary moving platform 6 is equipped with a rotary drive mechanism. The rotary motor 9 meshes with the gear ring 12 on the outer edge of the rotating disk 11 through the pinion 13 mounted on the reducer output shaft, forming a complete rotary transmission system. The rotating disk 11 has a square placement opening 14 in the center for accommodating the end of the crossbeam. Four clamping cylinders 15 are evenly distributed around the placement opening 14. The piston rod end of the cylinder is equipped with a rubber clamping block, which can firmly clamp crossbeams of different sizes.

[0020] During operation, the operator places both ends of the crossbeam to be processed into the placement openings 14 of the two rotating disks 11. The translation cylinder 4 pushes the auxiliary moving table 6 towards the center, positioning the crossbeam in the processing position. Simultaneously, the clamping cylinder 15 actuates, firmly securing both ends of the crossbeam. According to a preset program, the control system directs the translation motor 3 to drive the main moving table 5 to the first punching position, where the punching assembly 8 completes the punching operation. When the other side of the crossbeam needs to be processed, the rotary motor 9 rotates the rotating disk 11 180 degrees, aligning the surface to be processed with the punching assembly 8. The entire process requires no manual flipping of the crossbeam.

[0021] This device coordinates the sequence and timing of actions of each actuator through an electrical control system. The control system uses PLC programming control, enabling automatic positioning, automatic punching, and automatic flipping functions. Operators only need to input processing parameters on the touchscreen, and the device can automatically complete the entire processing, significantly improving processing efficiency and accuracy. The device is also equipped with safety protection devices, including an emergency stop button and light curtain protection, to ensure operational safety. Example

[0022] In this embodiment, the main moving platform 5 is fixedly equipped with a collection box 16, which is located directly below the punching assembly 8. This collection box 16 is used to collect metal debris generated during the punching process. The collection box 16 features an inclined design with a guide channel at its bottom, allowing debris to automatically slide into the box. An openable and closable baffle is located at the front of the box; when debris accumulates to a certain amount, the baffle can be opened for cleaning. The collection box 16 is bolted to the main moving platform 5 to ensure stability during movement.

[0023] The collection box 16 is equipped with a filter layer inside to separate larger metal shavings from fine dust. The filter is removable for easy regular cleaning and maintenance. An observation window is located on the side of the box, allowing operators to visually monitor the accumulation of debris. An exhaust duct is connected to the rear of the collection box 16. External ventilation equipment generates negative pressure to draw in and centrally process the dust generated during punching, improving the working environment.

[0024] The working principle of this collection device is as follows: when the punching assembly 8 punches the crossbeam, the resulting metal debris falls naturally under gravity. Since the collection box 16 is located directly below the punch and moves synchronously with the main moving table 5, it can accurately collect punching debris from all locations. The inclined design of the box allows the debris to automatically slide towards the collection area, preventing accumulation at the inlet. The airflow generated by the exhaust system sucks in fine dust for processing, preventing dust dispersion.

[0025] The linkage design between the collection box 16 and the punching assembly 8 ensures that the collection box 16 can reach the punching point in a timely manner no matter where the main moving table 5 moves. This synchronous movement collection method solves the problem of missed connections in traditional fixed collection devices. At the same time, since the collection box 16 moves as an integral part of the main moving table 5, no additional drive mechanism is required, simplifying the device structure.

[0026] In practice, the installation position of the collection box 16 is precisely calculated to ensure that its opening edge maintains an appropriate distance from the punch of the punching assembly 8, thus not affecting the punching operation while effectively collecting debris. The box body is made of wear-resistant material to extend its service life. The entire collection system works in coordination with other components of the punching device to improve processing efficiency and the quality of the working environment.

[0027] The collection box 16 in this embodiment is designed with actual production needs in mind. Through a reasonable structural layout and functional configuration, it achieves automatic collection and processing of punching debris. Compared with the prior art, this design not only solves the debris collection problem, but also avoids the occupation of additional space through an integrated solution, maintaining the integrity of the device and ease of operation. Example

[0028] The protective shell 17 on the outside of the translation motor 3 and the rotary motor 9 in this embodiment adopts a split structure design. The protective shell 17 consists of upper and lower parts connected by bolts, which facilitates disassembly and maintenance. The inner wall of the protective shell 17 is provided with a buffer layer made of elastic material, which can effectively absorb external impact. The opening of the protective shell 17 is provided with a labyrinth-type sealing structure to prevent metal debris generated during processing from entering the motor. The top of the protective shell 17 is designed with an array of heat dissipation holes, and the holes are arranged at an angle to ensure heat dissipation and block vertically falling debris.

[0029] The protective housing 17 and the motor mounting base are connected by a floating connection, using rubber shock-absorbing pads to achieve a flexible connection and prevent motor vibration from being directly transmitted to the protective housing 17. A transparent observation window made of impact-resistant polycarbonate material is located at the front of the protective housing 17, facilitating observation of the motor's operating status. A chip collection groove is designed at the bottom of the protective housing 17 to collect small amounts of debris seeping into the labyrinth seal; the groove is a detachable structure. A temperature sensor is installed on the side of the protective housing 17 to monitor the motor's operating temperature in real time.

[0030] The installation position of the protective housing 17 is precisely calculated to ensure a sufficient safe distance from the rotating parts of the motor. The inner surface of the protective housing 17 is polished to reduce frictional resistance with the motor housing. The protective housing 17 is designed to open from the side to avoid affecting the operating space of the upper equipment during maintenance. The locking mechanism of the protective housing 17 adopts an anti-loosening design to ensure that it will not be accidentally opened under equipment vibration.

[0031] The protective shell 17 is made of high-strength aluminum alloy, which reduces overall weight while ensuring protective performance. The edges of the protective shell 17 are flanged to improve structural strength and prevent injury from sharp edges. An internal baffle is installed in the protective shell 17 to optimize airflow for heat dissipation. A rubber sealing strip is used at the interface between the protective shell 17 and the equipment frame to prevent debris from entering through gaps.

[0032] The maintenance door of the protective housing 17 is designed with a safety interlock device, which automatically cuts off the motor power when the door is opened. The surface of the protective housing 17 is anodized to improve its corrosion resistance. The fixing bolts of the protective housing 17 are made of stainless steel to prevent rust from affecting disassembly. The protective housing 17 has a reserved wiring channel inside for convenient and standardized arrangement of motor cables.

[0033] The overall structure of the protective housing 17 has been optimized through finite element analysis, achieving a lightweight design while ensuring protective performance. The mounting bracket of the protective housing 17 features an adjustable design for easy alignment with the motor mounting position. A ring-shaped lighting strip is installed around the observation window of the protective housing 17 to improve internal observation conditions. Dust filters are installed at the ventilation holes of the protective housing 17, which can be cleaned and replaced periodically.

[0034] The design of the protective enclosure 17 fully considers ease of maintenance, with sufficient operating space on all major maintenance surfaces. The protective enclosure 17 has a complete labeling system, including warning signs, operating instructions, and equipment parameters. The protective enclosure 17 has robust grounding measures to ensure safe discharge of static electricity. The opening angle of the protective enclosure 17 is ergonomically optimized for easy maintenance by operators. Example

[0035] The rotary disk 11 in this embodiment is made of iron and is movably mounted on the auxiliary moving table 6 via a support plate 10. A placement opening 14 for placing the crossbeam is located at the center of the rotary disk 11, and four clamping cylinders 15 are evenly distributed around the periphery of the placement opening 14 to fix both ends of the crossbeam. A gear ring 12 is fixedly mounted on the outer edge of the rotary disk 11, meshing with a gear 13 on the output shaft of the rotary motor 9 to form a transmission connection. When it is necessary to adjust the machining surface of the crossbeam, the rotary motor 9 drives the gear ring 12 through the gear 13, causing the entire rotary disk 11 to rotate, thereby changing the machining angle of the crossbeam.

[0036] The iron rotating disk 11 has high hardness and strength, enabling it to withstand the impact and torque generated during punching. During punching operations, the crossbeam is fixed to the rotating disk 11 by the clamping cylinder 15. The iron rotating disk 11 effectively resists the vibrations generated during punching, maintaining processing stability. Simultaneously, the iron material has good wear resistance, extending the service life of the rotating disk 11 and reducing maintenance frequency.

[0037] When the device is in operation, the two ends of the crossbeam to be processed are first aligned with the placement openings 14 of the rotating disk 11. The translation cylinder 4 drives the auxiliary moving table 6 to move along the slide rail 2, so that the two ends of the crossbeam enter the placement openings 14. The clamping cylinder 15 is activated to firmly clamp the crossbeam onto the rotating disk 11. The translation motor 3 drives the main moving table 5 through the lead screw 7, which moves the punching assembly 8 to the predetermined punching position. After punching one side is completed, if other sides need to be processed, the rotary motor 9 drives the rotating disk 11 to rotate by a specified angle so that the new processing surface is facing the punching assembly 8.

[0038] The iron rotating disk 11 has excellent thermal conductivity, enabling it to quickly dissipate heat generated during processing and preventing dimensional deformation due to temperature rise. Furthermore, iron has excellent machinability, facilitating the manufacture of a high-precision rotating disk 11 to ensure the accuracy of beam clamping and rotation. Compared to other metal materials, iron is less expensive, which helps reduce the overall manufacturing cost of the device.

[0039] During long-term use, the surface of the iron rotating disk 11 can be heat-treated or coated to further improve its surface hardness and corrosion resistance. The rotating disk 11 is connected to the support plate 10 using bearings to ensure smooth rotation. The gear ring 12 is fixed to the rotating disk 11 with high-strength bolts to ensure reliable transmission. The entire rotating mechanism has a compact design, occupies little space, and facilitates multi-angle punching within a limited working area.
