Description

Technical Field

[0001] This utility model belongs to the field of multi-wire cutting, specifically relating to a support arm fork assembly and a loading trolley for a multi-wire cutting machine. Background Technology

[0002] Multi-wire cutting machines typically use high-speed reciprocating metal wires to drive abrasive particles for grinding and cutting when cutting hard materials, capable of cutting materials into hundreds or even thousands of thin slices in a single pass. In a multi-wire cutting machine, the grooved rollers are key components that support and guide the movement of the metal wires, usually installed on both sides of the cutting area. Their function is to maintain the spacing and tension of the metal wires through orderly arranged grooves, ensuring stable operation of the metal wires during the cutting process. Due to the significant weight of the material and the grooved rollers, loading and unloading operations are usually performed using a loading trolley when cutting materials or installing the grooved rollers.

[0003] However, the existing loading trolleys have some drawbacks: Firstly, the fixed arm spacing of the loading trolleys means that each trolley can only accommodate a single type of material. When the production line is equipped with multi-wire cutting machines of different specifications, multiple loading trolleys need to be configured, which not only increases equipment costs but also affects operating efficiency. Secondly, since the length of the grooved wheel is usually much greater than the width of the material, the spacing between the grooved wheel arms is much greater than the spacing between the material arms. The loading trolley needs to be equipped with both material arms and grooved wheel arms. When switching between loading and unloading objects, different arms need to be repeatedly replaced, making the operation process cumbersome and affecting production efficiency.

[0004] The present invention aims to provide a support arm fork assembly and a multi-wire cutting machine loading trolley to solve the above-mentioned technical problems.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: to provide a support arm fork assembly, comprising:

[0006] The mounting panel is equipped with a hinge.

[0007] A support bracket, mounted on the mounting panel and located below the rotating shaft, includes a connecting portion and a horizontal positioning portion, wherein the connecting portion is connected to both the mounting panel and the horizontal positioning portion, and a plurality of positioning slots are spaced apart on the upper end surface of the horizontal positioning portion; and

[0008] A pair of support arms are slidably mounted on the rotating shaft, wherein at least one of the support arms is capable of flipping up and down around the rotating shaft and is capable of translating along the rotating shaft to adapt to materials or grooved wheels of different widths, and the support arm is adapted to be confined within the positioning slot;

[0009] During feeding, one of the support arms adjusts its position on the rotating shaft based on the width of the material or groove wheel and engages in the positioning slot, with the corresponding material or groove wheel fixed on the support arm.

[0010] In this embodiment, when it is necessary to feed materials of different sizes, simply lift one side of the support arm and move it to a suitable distance, then place it into the corresponding positioning slot for fixing. This allows for quick adjustment of the support arm spacing to adapt to the feeding requirements of materials of different specifications. Furthermore, by adopting the solution of this application, only a pair of support arms need to be set on the feeding trolley to simultaneously meet the feeding operation of the material box groove wheel. There is no need to replace or add additional support arms, which improves the versatility of the device, simplifies the device structure, reduces production costs, and is simple and convenient to use.

[0011] In one embodiment, the connecting part includes a pair of vertical beams mounted on the mounting panel and a horizontal beam connected to the vertical beams, and the horizontal positioning part includes a positioning plate fixed on the horizontal beam, and the positioning slot is formed on the positioning plate;

[0018] In one embodiment, a pair of limiting blocks are provided on the upper end face of each of the support arms;

[0019] When feeding the grooved wheel, the grooved wheel is fixed between the limit blocks.

[0020] On the other hand, this utility model provides a feeding trolley for a multi-wire cutting machine, comprising:

[0021] The frame includes a base and a vertical support frame, the base being fitted with casters;

[0022] The lifting frame is slidably mounted on the support frame and has a degree of freedom to move up and down along the support frame; and

[0048] 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.

[0049] 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.

[0050] It should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. 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.

[0051] 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.

[0052] Multi-wire cutting machines are widely used in the processing of hard and brittle materials, achieving precision cutting through high-speed reciprocating metal wires. For large multi-wire cutting equipment, due to the large weight of the materials to be cut and the guide rollers, a dedicated loading trolley is usually required for loading and unloading operations. Currently, traditional loading trolleys mainly adopt a fixed-spacing support arm design, which has the following limitations: First, each loading trolley can only accommodate a single material size. When the production line needs to process materials of different sizes, multiple dedicated loading trolleys must be configured, which not only increases equipment investment costs but also occupies production space. Second, due to the significant size difference between the rollers and the materials (the length of the rollers is usually much greater than the width of the materials), existing loading trolleys need to be equipped with two sets of support systems: material support arms and roller support arms. Frequent replacement of support arms is required when switching between loading and unloading objects, resulting in cumbersome operation procedures and affecting production efficiency.

[0053] The support arm fork assembly and multi-wire cutting machine loading trolley provided in this application, through the adjustable spacing of the support arms, allow operators to quickly adapt to materials of different sizes simply by lifting and moving one side of the support arm to the appropriate position and fixing it. This significantly improves the convenience and efficiency of the loading operation and enhances the trolley's adaptability to different material types. Furthermore, using the above concept, only one pair of support arms can simultaneously meet the loading needs of both materials and rollers, eliminating the need to replace or add dedicated support arms for different loading objects, further improving the versatility of the loading trolley.

[0054] Please refer to the attached document as well. Figure 1 To be continued Figure 4The present invention provides a description of the support arm fork assembly and the multi-wire cutting machine loading trolley. The support arm fork assembly includes a mounting panel 04, a support frame, and a pair of support arms 02. The support arms 02 can move horizontally along the support frame to adapt to the width of different materials. Alternatively, when the loading trolley is used for loading with grooved wheels, the spacing between the support arms 02 can be directly changed to adapt to the grooved wheels without the need for additional replacement of the support arms 02. Specifically, a rotating shaft 041 is mounted on the mounting panel 04. The support frame is mounted on the mounting panel 04 and located below the rotating shaft 041. The support frame includes a connecting part 03 and a horizontal positioning part. The connecting part 03 is connected to the mounting panel 04 and the horizontal positioning part respectively. Multiple positioning slots 0311 are spaced apart on the upper surface of the horizontal positioning part. A pair of support arms 02 are slidably mounted on a rotating shaft 041. At least one support arm 02 is capable of rotating up and down around the rotating shaft 041 and can translate along the rotating shaft 041 to adapt to materials or grooved wheels of different widths. The support arm 02 is adapted to be positioned within a positioning slot 0311. During loading, one of the support arms 02 adjusts its position on the rotating shaft 041 based on the width of the material or grooved wheel and engages in the positioning slot 0311, thus fixing the corresponding material or grooved wheel onto the support arm 02.

[0055] In one embodiment, only one support arm 02 is movable. A positioning slot 0311 is provided on one side of the horizontal positioning part, and the corresponding support arm 02 is rotatably assembled with the rotating shaft 041 and always fixed in the positioning slot 0311. Multiple positioning slots 0311 are provided on the other side of the horizontal positioning part, and the corresponding support arm 02 can move horizontally along the rotating shaft 041 and is limited in different positioning slots 0311 based on the different widths of the material or the wheel. In use, the position of the single-sided support arm 02 is adjusted to accommodate materials or wheels of different sizes.

[0056] In another embodiment, both support arms 02 are adjustable. Multiple positioning slots 0311 are symmetrically provided on both sides of the horizontal positioning part. Both support arms 02 can move horizontally along the rotating shaft 041. In use, the position of the two support arms 02 can be arbitrarily adjusted according to the width of the material or the groove wheel to obtain a suitable spacing, and the support arms 02 are limited in the corresponding positioning slots 0311.

[0057] In this embodiment, the adjustable design of the support arm 02 enables rapid adaptation to various material specifications, ensuring the reliability of material feeding and positioning, expanding the applicability of the feeding trolley, and allowing the same equipment to meet the feeding requirements of both materials and groove wheels without the need to replace the support arm 02, thus simplifying the production process and improving work efficiency.

[0058] Furthermore, the support frame is equipped with handles 05 on the back to facilitate transportation by staff.

[0059] In one specific embodiment, please refer to the appendix. Figure 4The connecting part 03 includes a pair of vertical beams 033 mounted on the mounting panel 04 and a horizontal beam 032 connected to the vertical beams 033. The horizontal positioning part includes a positioning plate 031 fixed on the horizontal beam 032, and a positioning slot 0311 is formed on the positioning plate 031. The bottom end of the positioning slot 0311 is fitted with a leveling bolt 0312 that can abut against the bottom of the support arm 02. When fixing the support arm 02, the leveling bolt 0312 supports the support arm 02 from the bottom. By rotating the leveling bolt 0312, the support arm 02 is lifted up to accurately adjust the horizontal position of the support arm 02, ensuring that the contact surface between the support arm 02 and the material remains flat. This not only enhances the load-bearing stability of the support arm 02, but also effectively compensates for minor deformations caused by processing errors or long-term use, making the loading and positioning more accurate and reliable.

[0060] In one specific embodiment, please refer to the appendix. Figure 2 The support arm fork assembly also includes a feeding plate for securing materials. A fork 021 is mounted on the inner side of the support arm 02. Specifically, the fork 021 includes a vertically formed connecting plate and a limiting plate, with the limiting plate fixedly mounted to the support arm 02 via the connecting plate. Grooves matching the limiting plates are formed on both sides of the feeding plate along its length. When feeding materials, the materials adhere to the upper surface of the feeding plate, and the limiting plates of the fork 021 are adapted to engage with the grooves on both sides of the feeding plate to secure the materials.

[0061] Furthermore, the end of the feed fork 021 is chamfered to facilitate insertion into the groove of the feed plate.

[0062] In one specific embodiment, each support arm 02 has a pair of limiting blocks 022 on its upper surface. When feeding the grooved wheel, the grooved wheel is fixed between the limiting blocks 022. Specifically, the limiting blocks 022 are block-shaped structures, and the opposite ends of the two limiting blocks 022 are provided with limiting inclined surfaces suitable for matching the circumferential surface of the grooved wheel.

[0063] On the other hand, please see the appendix Figure 1 This utility model also provides a loading trolley for a multi-wire cutting machine, which includes a frame 01, a lifting frame 06, and a support arm fork assembly. The lifting frame 06 is movably mounted on the frame 01 and is used to drive the support arm fork assembly to lift and lower. Specifically, the frame 01 includes a base 09 and a vertical support frame, and the base 09 is equipped with pulleys 08. The lifting frame 06 is slidably mounted on the support frame and has a degree of freedom of lifting and lowering along the support frame. The mounting panel 04 of the support arm fork assembly is movably mounted on the lifting frame 06 and can slide along the horizontal direction of the lifting frame 06.

[0064] In one specific embodiment, a pair of mounting plates 061 are fixed to the back of the lifting frame 06, and the mounting plates 061 are slidably mounted on the support frame. A vertically arranged lifting drive component is mounted on the support frame, and the driving end of the lifting drive component is connected to the lifting frame 06 and is adapted to drive the lifting frame 06 to rise and fall.

[0065] In one specific embodiment, the mounting panel 04 slides horizontally along the lifting frame 06 via a horizontal drive mechanism 07, wherein the horizontal drive mechanism 07 includes a lead screw 072 and a lead screw nut 071 assembly and a guide rod 073. The lead screw 072 and lead screw nut 071 assembly are mounted on the lifting frame 06. The guide rod 073 is mounted on the lifting frame 06 parallel to the lead screw 072. A first mounting member 042 and a second mounting member 074 are respectively mounted on the back of the mounting panel 04, which are fitted with the lead screw nut 071 and the guide rod 073 of the lead screw 072 and lead screw nut 071 assembly.

[0066] Furthermore, the second mounting component 074 is a slider that is fixed to the mounting panel 04 by bolts. The slider slides through the guide rod 073 and is used to guide and limit the mounting panel 04. A linear bearing is assembled between the slider and the guide rod 073.

[0067] In one specific embodiment, the first mounting member 042 has a limiting groove 0421 on the side facing the lead screw 071. The lead screw 071 is nested in the limiting groove 0421, and there is a certain gap between the upper and lower end faces of the lead screw 071 and the limiting groove 0421. By setting the structure of the lead screw 071 and the first mounting member 042 with clearance fit, when there is a parallelism deviation between the first mounting member 042 and the lead screw 072, the lead screw 071 can adaptively adjust its position within the gap range, avoiding jamming problems caused by assembly errors or deformation. While ensuring transmission accuracy, it increases the fault tolerance of the mechanism, allowing the lead screw 072 to rotate smoothly and ensuring stable execution of translational movements. Compared with the traditional rigid connection method, this structure reduces the requirements for processing and assembly accuracy, improves the reliability and service life of the equipment, and reduces maintenance needs caused by misalignment.

[0068] 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.
