Description

Technical Field

[0001] This utility model belongs to the field of multi-wire cutting, specifically relating to a rotary feeding mechanism and a feeding trolley for a multi-wire cutting machine. Background Technology

[0002] A multi-wire cutting machine is a device used for cutting hard materials. It cuts the material into hundreds or thousands of thin slices using a high-speed reciprocating metal wire. In a multi-wire cutting machine, grooved rollers are used to support and guide the movement of the metal wire, and are usually installed on both sides of the cutting area. The grooved rollers have multiple grooves to guide the metal wire, maintaining spacing and tension. Due to the large weight of the material to be cut or the grooved rollers, a loading trolley is usually required for loading and unloading. For some inverted cutting models, the material needs to be rotated 180° before loading. Currently, the common loading method is to first adhere the material to be cut to the loading plate, then invert it manually or with auxiliary equipment, and finally load it using a loading trolley.

[0003] Manual or auxiliary equipment loading operations are cumbersome and inefficient. In addition, there is a risk of material falling off or shifting during the inversion process. Furthermore, handling and flipping materials increases the labor intensity of workers and affects overall production efficiency. Utility Model Content

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a rotary feeding mechanism, comprising:

[0006] The mounting bracket includes a first mounting part and a second mounting part disposed opposite to each other by means of a connector, wherein the first mounting part has an assembly part for cooperating with a loading trolley on the side away from the second mounting part;

[0007] A vertical shaft gearbox is mounted on the side of the second mounting portion facing the first mounting portion, wherein the vertical shaft gearbox is mounted by means of a mounting base fixedly connected to the second mounting portion, the drive shaft of the vertical shaft gearbox passes through the mounting base, and an input shaft is provided on the end face of the vertical shaft gearbox adjacent to the drive shaft, the input shaft being perpendicular to the drive shaft and extending to the outside of the second mounting portion; and

[0008] The support arm assembly includes an end plate fixedly connected to the drive shaft of the vertical shaft gearbox, and a pair of support arms connected to the end plate. The support arm assembly is capable of flipping under the rotational drive of the vertical shaft gearbox.

[0009] During feeding, the material or groove wheel is fixed on the support arm. When it is necessary to cut the material, the support arm is rotated downwards by 180°.

[0010] The embodiments of this application realize rapid material flipping and feeding, simplify the feeding operation steps, improve production efficiency, effectively avoid the risk of material falling off due to manual flipping, ensure the accuracy of feeding positioning, and greatly reduce the labor intensity of workers.

[0016] In this embodiment, a multi-stage helical gear reducer drives the support arm assembly to achieve material flipping. Utilizing the torque-increasing characteristics of multi-stage gear transmission, only a small driving force needs to be applied at the input end of the reducer to obtain a significantly amplified output torque at the output end, easily completing the material flipping action. Furthermore, the gear transmission structure or worm gear transmission structure of the reducer has high meshing precision, preventing jamming or even failure to rotate when driving the support arm assembly to flip, ensuring the reliability of the device.

[0017] In one embodiment, the support arm assembly further includes a feed plate for securing materials or a wheel;

[0018] Each support arm is fixedly provided with a support plate, and a pair of limiting blocks are fixedly provided on the upper surface of each of the two support plates.

[0019] When the material is fed, it adheres to the feeding plate. The tray is inserted into the grooves on both sides of the feeding plate to fix the material. The support arm can drive the material to flip.

[0020] When the grooved wheel is loaded, the grooved wheel is fixed between the limit blocks.

[0021] The embodiments of this application can adapt to both material feeding operations and the feeding requirements of Geneva wheels, realizing the function of one machine for multiple purposes. This avoids the trouble of configuring different feeding devices in traditional equipment, simplifies the equipment structure, and reduces the cost of use. At the same time, this universal design improves the adaptability and ease of operation of the equipment.

[0060] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model 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 of the present utility model and are not intended to limit the present utility model.

[0061] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly on or indirectly on that other component. When a component is referred to as being "connected to" another component, it can be directly connected to or indirectly connected to that other component.

They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0063] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0064] When processing hard materials, multi-wire EDM machines often require a feeding mechanism to clamp and position the material. For applications requiring inverted cutting, the material must be rotated 180 degrees before cutting. Currently, the common method is to first adhere the material to the feeding plate, then manually or with auxiliary equipment invert and secure it to a feeding trolley, which then transports it to the processing position. This method requires multiple people or additional auxiliary equipment to invert the material, making the process cumbersome and complex. Furthermore, there is a risk of material falling off during inversion, affecting processing efficiency and quality. The entire feeding process is time-consuming and labor-intensive.

[0065] This invention utilizes a vertical shaft gearbox to drive the support arm to rotate, eliminating the need for significant manpower or auxiliary equipment to invert materials. This simplifies the operation and improves work efficiency. Furthermore, the stability of the gearbox transmission ensures the reliability of the rotation action, preventing material spillage that can occur during manual inversion. It also reduces the workload of workers; the loading action, which previously required multiple people, can now be easily completed by just one person, providing a strong guarantee for the continuous and efficient operation of the production line.

[0066] To solve the above-mentioned technical problems, this utility model provides a rotary feeding mechanism and a feeding trolley for a multi-wire cutting machine. Please refer to the appendix for details. Figure 1 To be continued Figure 4 The rotary feeding mechanism provided by this utility model is described below. The rotary feeding mechanism includes a mounting frame 03, a vertical shaft gearbox 07, and a support arm assembly. The vertical shaft gearbox 07 is mounted on the feeding trolley via the mounting frame 03. The support arm assembly rotates under the drive of the vertical shaft gearbox 07, thereby causing the material 10 to rotate. Specifically, the mounting frame 03 includes a first mounting part 031 and a second mounting part 033 arranged opposite each other via a connecting member 032. The side of the first mounting part 031 away from the second mounting part 033 has an assembly part for cooperating with the feeding trolley. Specifically, the first mounting part 031, the second mounting part 033, and the connecting member 032 are all plate-shaped structures. The first mounting part 031 has multiple assembly holes and is bolted to the feeding trolley. The connecting member 032 is assembled on the upper and lower sides of the second mounting part 033 and fixed to the second mounting part 033 by bolts. A vertical shaft gearbox 07 is mounted on the side of the second mounting portion 033 facing the first mounting portion 031. The vertical shaft gearbox 07 is mounted via a mounting base fixedly connected to the second mounting portion 033. The drive shaft of the vertical shaft gearbox 07 passes through the mounting base. An input shaft is located on the end face of the vertical shaft gearbox 07 adjacent to the drive shaft. The input shaft is perpendicular to the drive shaft and extends to the outside of the second mounting portion 033. The input shaft on the side of the vertical shaft gearbox serves as the power input end. Torque applied to the input shaft is converted into vertical output power via the transmission structure inside the gearbox, driving the support arm assembly to perform a tilting action. The support arm assembly includes an end plate 041 fixedly connected to the drive shaft of the vertical shaft gearbox 07, and a pair of support arms 09 connected to the end plate 041. The support arm assembly can tilt under the rotational drive of the vertical shaft gearbox 07. During loading, the material 10 or the pulley 16 is fixed on the support arm 09. When it is necessary to cut the material 10, the support arm 09 tilts downwards by 180°.

[0067] In this embodiment of the application, by setting a vertical shaft gearbox 07, the automatic flipping function of the material 10 is realized, which effectively solves the problems of low efficiency and high labor intensity of traditional manual flipping operation. It not only improves the feeding efficiency, but also avoids the safety hazards that may be caused by manual operation.

[0068] In one embodiment, a pair of support arms 09 are positioned at opposite ends of the lower part of the end plate 041. The support arms, located at the bottom of the end plate, lower the center of gravity of the material, bringing it closer to the rotation axis of the support arm assembly. This prevents material displacement during rotation and improves the stability of the flipping action. A reinforcing plate 042 is fixed between the end plate 041 and the support arms 09, reducing stress concentration at the connection point and ensuring the support arms 09 are securely installed, thus enhancing their load-bearing capacity. Furthermore, a crossbeam 08 is fixed between the two support arms 09, forming a more robust rigid frame structure. This prevents deformation of the support arms 09 when carrying heavy materials 10, enhances the smoothness of the flipping action, and better maintains the precise positioning of the material 10, ensuring positional accuracy during the cutting process.

[0069] In one embodiment, the operator can manually adjust the flipping action. A handwheel is mounted on the input shaft of the vertical axis gearbox 07, allowing the operator to easily rotate the input shaft of the vertical axis gearbox 07.

[0070] Furthermore, a support plate 18 is fixedly mounted on one side of the second mounting part 033. The input shaft of the vertical shaft gearbox 07 passes through the support plate 18 and can rotate relative to the support plate 18. A bearing is assembled between the input shaft and the support plate 18. During installation, the input shaft of the vertical shaft gearbox 07 can be positioned through the support plate 18 to ensure installation accuracy.

[0071] In one specific embodiment, the vertical shaft gearbox preferably adopts a multi-stage helical gear reducer. Through the torque amplification effect of the multi-stage gear pair, the material can be flipped without applying a large torque at the input end of the reducer, thus saving manpower.

[0072] It should be noted that multi-stage gear transmission has a large reduction ratio, and the torque required for reverse drive is also large. Therefore, multi-stage helical gear reducers have a certain degree of self-locking characteristics, ensuring that even if the output end is subjected to force during feeding, it is difficult to reverse drive the input end, thereby ensuring that the material can be stably maintained at a specific flipping angle without rotating on its own.

[0073] Alternatively, in another specific embodiment, the vertical shaft gearbox can also be a worm gear reducer, whose self-locking function can ensure stable material feeding.

[0074] In the above embodiments, because the gear pairs or worm gears in the reducer have high meshing precision, the flipping action can be completed smoothly, and it is not easy for jamming or failure to rotate to occur.

[0075] In one embodiment, the support arm assembly further includes a feeding plate 17 for fixing the material 10 or the grooved wheel 16. Each support arm 09 is fixedly provided with a support plate 05, and a pair of limiting blocks 06 are fixedly provided on the upper end face of each support plate 05. When the material 10 is fed, the material 10 adheres to the feeding plate 17, and the support plate 05 is engaged in the grooves on both sides of the feeding plate 17 to fix the material 10. The support arm 09 can drive the material 10 to rotate. When the grooved wheel 16 is fed, the grooved wheel 16 is fixed between the limiting blocks 06. Specifically, the groove extends along the length of the feeding plate 17, and during assembly, the support plate 05 is inserted into the groove in a horizontal direction.

[0076] In this embodiment, the feeding mechanism can be used for feeding materials 10 and for feeding the groove wheel 16, which solves the problem of needing to change special equipment for different feeding objects in traditional equipment, realizes multi-purpose use of one machine, eliminates the need to change the support arm 09, simplifies the feeding operation process, and makes the production operation more continuous and efficient.

[0077] Furthermore, to facilitate the insertion of the pallet 05 into the groove of the feeding plate 17, the end of the pallet 05 is chamfered.

[0078] On the other hand, this utility model provides a multi-wire cutting machine loading trolley, which includes a frame and the rotary loading mechanism provided in the aforementioned embodiment. The frame includes a base 12 and a vertical support frame 01, and the base 12 is equipped with wheels 13. The first mounting part 031 of the rotary loading mechanism is movably mounted on the support frame 01 and can slide along the horizontal direction of the lifting frame 14.

[0079] During loading, material 10 is assembled on the support arm assembly and transported to the multi-wire cutting machine by the loading trolley. The support arm 09 is controlled to move horizontally and move material 10 to the predetermined position. The vertical shaft gearbox 07 drives the support arm 09 to rotate 180°, thereby inverting material 10 for easy cutting.

[0080] In one embodiment, a pair of mounting plates 141 are fixedly mounted on the side of the first mounting portion 031 away from the second mounting portion 033, and the mounting plates 141 are slidably mounted on the support frame 01. A vertically arranged lifting drive component 11 is mounted on the support frame 01, and the driving end of the lifting drive component 11 is connected to the first mounting portion 031 and is adapted to drive the mounting frame 03 to rise or fall. Specifically, the lifting drive component 11 is a cylinder or an electric push rod.

[0081] In one embodiment, the first mounting part 031 slides horizontally along the lifting frame 14 via a horizontal drive mechanism 15, wherein the horizontal drive mechanism 15 includes a lead screw 151 and a lead screw nut 152 assembly and a guide rod 155. The lead screw 151 and lead screw nut 152 assembly is mounted on the lifting frame 14. The guide rod 155 is mounted on the lifting frame 14 parallel to the lead screw 151. A first mounting member 153 and a second mounting member 154 are respectively mounted on the back of the first mounting part 031, which are fitted with the lead screw nut 152 and the guide rod 155 of the lead screw 151 and lead screw nut 152 assembly. During loading, rotating the lead screw 151 controls the horizontal movement of the lead screw nut 152, thereby driving the loading mechanism to move horizontally. Specifically, the second mounting component 154 is a slider that is fixed to the first mounting part 031 by bolts. The slider slides through the guide rod 155, and a linear bearing is installed between the slider and the guide rod 155 to limit the first mounting part 031, prevent the operator from accidentally lifting the feeding mechanism, and thus avoid damaging the lead screw 151.

[0082] In one embodiment, a limiting groove is formed on the first mounting member 153. A nut 152 is fitted into the limiting groove, and a limiting plate is formed at the end of the nut 152 to abut against the first mounting member 153. A certain gap is provided between the upper and lower end faces of the nut 152 and the limiting groove, allowing the nut 152 to retain adequate movement space within the first mounting member 153. This ensures that the nut 152 can automatically fine-tune its position to adapt to parallelism deviations and avoid jamming caused by assembly errors.

[0083] In one embodiment, the operator can manually adjust the horizontal displacement of the feeding mechanism. A handwheel is fixed at the end of the lead screw 151 for easy operation.

[0084] In one embodiment, the feeding mechanism is moved horizontally by a motor. The motor is mounted on the side of the mounting bracket 03, and the end of the lead screw 151 is connected to the output shaft of the motor.

[0085] In one embodiment, the support frame 01 is equipped with a handle 02 on its back, which facilitates the staff to push the loading trolley when transporting materials 10.

[0086] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
