Description

Technical Field

[0001] This utility model relates to the field of multi-wire cutting technology, specifically a loading and unloading vehicle that is compatible with a multi-wire cutting machine. Background Technology

[0002] Multi-wire cutting machines use the high-speed reciprocating motion of metal wires (cutting wires) to bring abrasive into the processing area of ​​the material to be cut for grinding, and simultaneously cut the workpiece into hundreds or thousands of thin slices. They have the advantages of high working efficiency and low material loss.

[0003] Before a multi-wire cutting machine can perform cutting operations, it must first complete the material bonding process, that is, attach the workpiece to the material plate. With the widespread application of multi-wire cutting technology, the size of the workpiece being cut is trending towards larger dimensions, leading to the development of oscillating multi-wire cutting machines, as shown in the attached image. Figure 1 The large workpiece 1 shown is cut using a table-swinging multi-wire cutting machine. During the cutting operation, workpiece 1 is suspended on the workpiece clamping seat of the swaying worktable via a material plate 2, and is fed downwards along with the swaying worktable. Before cutting, workpiece 1 and material plate 2 must first be transported from the ground to a height level with the material plate slide of the multi-wire cutting machine, and then enter the workpiece clamping position of the swaying worktable of the multi-wire cutting machine along the material plate slide. After the cutting process is completed, the workpiece must be lifted to a height level with the material plate slide by a lifting system, and then moved horizontally out of the multi-wire cutting machine along the material plate slide. Finally, the workpiece is transported to the ground for post-processing. Due to the large weight and volume of workpiece 1, it is difficult to achieve accurate and stable transport of the workpiece using existing hoisting tools (such as overhead cranes, existing loading and unloading vehicles, etc.). In addition, for table-swinging multi-wire cutting machines for large workpieces, the transfer of the wire pulleys and grooved pulleys during assembly and replacement also becomes a bottleneck restricting the improvement of work efficiency. Therefore, it is essential to design a specialized conveyor tool that matches the worktable swing-type multi-wire cutting equipment. Utility Model Content

[0004] This utility model provides a loading and unloading vehicle for a multi-wire cutting machine. It aims to improve work efficiency and ensure stable and accurate workpiece transportation by adding roller assemblies to the lifting frame of the loading and unloading vehicle and installing grooved wheel support plates or wire wheel lifting devices on the insertion frame, in conjunction with the loading and unloading system of the multi-wire cutting machine. At the same time, it solves the transfer problem during the assembly and replacement of wire wheels and grooved wheels.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A loading and unloading vehicle for a multi-wire cutting machine includes a frame, a lifting frame, and a mounting bracket. A lifting drive mechanism is provided on the frame, and the movement of the lifting frame can be controlled by the lifting drive mechanism. The lifting frame is assembled with the frame, and the mounting bracket is installed on the lifting frame. The special feature is that roller assemblies are provided on the left and right sides of the lifting frame.

[0007] The roller assembly includes several vertical rollers and at least two sets of horizontal rollers. The two sets of vertical rollers are arranged vertically and vertically. The vertical rollers are matched with the lifting rail and the horizontal rail of the multi-wire cutting machine loading and unloading system. The horizontal rollers are matched with the horizontal rail of the multi-wire cutting machine loading and unloading system.

[0008] The loading and unloading vehicle for the aforementioned multi-wire cutting machine includes two symmetrically arranged parts, and the structure and size of the insert are matched with the material plate slots provided on the material plate.

[0009] The loading and unloading vehicle for the aforementioned multi-wire cutting machine is equipped with a grooved wheel support plate on the insert frame. The grooved wheel support plate is detachably installed at the front end of the insert frame, and a positioning groove matching the outer circular surface of both ends of the grooved wheel is provided on the grooved wheel support plate.

[0010] The loading and unloading vehicle for the aforementioned multi-wire cutting machine is equipped with a wire wheel lifter on the insert frame. The wire wheel lifter includes a wire wheel slide and a wire wheel lifting plate. The wire wheel slide is fitted with the insert frame and can slide back and forth along the insert frame. A lifting hook is set under the wire wheel slide. The wire wheel lifting plate is connected to the lifting hook of the wire wheel slide through a lifting ring.

[0011] The loading and unloading vehicle for the aforementioned multi-wire cutting machine is equipped with casters and front rollers on its frame. The casters are installed at the bottom rear of the frame, and the front rollers are installed at the front end of the frame base. The front rollers are matched with the horizontal ground track of the multi-wire cutting machine's loading and unloading system.

[0012] The loading and unloading vehicle that is matched with the multi-wire cutting machine is also equipped with a push-pull handle on the frame, which is installed on the left and right uprights of the frame.

[0013] This invention provides a loading and unloading vehicle for a multi-wire cutting machine. By adding roller assemblies to the lifting frame of the vehicle and optionally installing grooved wheel support plates or wire wheel lifting devices on the mounting bracket, it works in conjunction with the loading and unloading system of the multi-wire cutting machine to transport large workpieces between the ground and the material tray slide of the machine. This invention also allows for the optional installation of grooved wheel support plates or wire wheel lifting devices on the mounting bracket, enabling the transfer of wire wheels and grooved wheels during assembly and replacement, respectively. In summary, this invention, in conjunction with the loading and unloading system of a multi-wire cutting machine, enables the transport of large workpieces between the ground and the material tray slide of the machine, while simultaneously solving the transfer problems during the assembly and replacement of wire wheels and grooved wheels, thereby improving work efficiency and ensuring stable and accurate workpiece transport.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0030] Referring to Figure 1, a large workpiece 1 is cut using a table-mounted multi-wire cutting machine. During the cutting operation, the workpiece 1 is suspended on the table via a material plate 2, so the bonding surface between the workpiece 1 and the material plate 2 is located on the upper surface of the workpiece 1. To facilitate the loading and unloading of the workpiece, a material plate slot 2-1 is provided in the material plate 2. During the cutting operation of the table-mounted multi-wire cutting machine, the workpiece 1 is suspended on the workpiece clamping seat of the table via the material plate 2, and the workpiece is fed by moving from top to bottom along with the table. Before the cutting operation, the workpiece 1 and the material plate 2 need to be transported from the ground to a height level with the material plate slide of the multi-wire cutting machine, and then enter the workpiece clamping position of the table-mounted multi-wire cutting machine along the material plate slide. After the cutting process is completed, the workpiece needs to be lifted to a height level with the material plate slide by a lifting system, and then moved horizontally out of the multi-wire cutting machine along the material plate slide. Finally, the workpiece is transported to the ground for post-processing. Due to the large weight and volume of workpiece 1, it is difficult to achieve accurate and stable transport of the workpiece using existing hoisting tools (such as overhead cranes and existing loading and unloading vehicles). In addition, for table-mounted multi-wire cutting equipment for large workpieces, the transfer of wire wheels and grooved wheels during assembly and replacement has become a bottleneck restricting the improvement of work efficiency.

[0031] See Figure 1 , Figure 2 , Figure 3 To solve the above problems, this utility model provides a loading and unloading vehicle 3 that matches a multi-wire cutting machine. The loading and unloading vehicle 3 includes a frame 3-1, a lifting frame 3-2, and a mounting bracket 3-4. A lifting drive mechanism is provided on the frame 3-1, which can control the movement of the lifting frame. The lifting frame 3-2 is assembled with the frame 3-1, and the mounting bracket 3-4 is installed on the lifting frame 3-2. The special feature is that roller assemblies 3-3 are provided on the left and right sides of the lifting frame 3-2.

[0032] See Figure 2 , Figure 3 , Figure 4 , Figure 6 , Figure 7 , Figure 8 , Figure 9 , Figure 10The roller assembly 3-3 of this utility model includes several vertical rollers 3-3-1 and at least two sets of horizontal rollers 3-3-2. The vertical rollers 3-3-1 are arranged in two sets, one vertically and one vertically. The vertical rollers 3-3-1 are matched with the lifting rail 4-2 and the horizontal rail 4-3 of the multi-wire cutting machine loading and unloading system. The horizontal rollers 3-3-2 are matched with the horizontal rail 4-3 of the multi-wire cutting machine loading and unloading system.

[0033] See Figure 1 , Figure 2 , Figure 5 The insert 3-4 of this utility model includes two parts arranged symmetrically on the left and right. The structure and size of the insert 3-4 match the material plate slot 2-1 provided on the material plate 2. The insert 3-4 passes through the material plate slot 2-1 provided on the material plate 2, thereby realizing the bearing function of the workpiece 1.

[0034] See Figure 2 , Figure 3 To solve the problem of transfer during the assembly and replacement of grooved wheels and wire wheels in the workbench oscillating multi-wire cutting machine 4, a grooved wheel support plate 3-5 or a wire wheel hanger 3-6 is optionally installed on the insert 3-4 of this utility model; the grooved wheel support plate 3-5 is detachably installed at the front end of the insert 3-4, and a positioning groove 3-5-1 matching the outer circular surface of both ends of the grooved wheel of the multi-wire cutting machine is provided on the grooved wheel support plate 3-5. The grooved wheel of the workbench oscillating multi-wire cutting machine 4 can be supported by the grooved wheel support plate 3-5, and the transfer of the grooved wheel is realized by the loading and unloading system of the multi-wire cutting machine; The wire wheel lifter 3-6 includes a wire wheel slide 3-6-1 and a wire wheel lifting plate 3-6-2. The wire wheel slide 3-6-1 is fitted outside the insert frame 3-4 and can slide back and forth along the insert frame 3-4. A hook is set under the wire wheel slide 3-6-1. The wire wheel lifting plate 3-6-2 is connected to the hook of the wire wheel slide 3-6-1 through a lifting ring. The wire wheel can be assembled with the wire wheel of the worktable swing-type multi-wire cutting machine through the wire wheel lifting plate 3-6-2, and the wire wheel is lifted by the wire wheel slide 3-6-1. The transfer of the wire wheel is realized by the loading and unloading system of the multi-wire cutting machine.

[0035] See Figures 5 to 10When using this utility model in conjunction with the multi-wire cutting machine loading and unloading system for loading and unloading operations of the worktable swing-type multi-wire cutting machine 4, the lifting frame 3-2 can be adjusted to a suitable position under the control of the lifting drive mechanism of the loading and unloading vehicle 3, so that the insert 3-4 passes into the material plate slot 2-1 of the top material plate 2 of the workpiece 1. Then, the lifting frame 3-2 is adjusted to a set height to complete the loading operation of the workpiece 1 on the loading and unloading vehicle 3. The loading and unloading vehicle 3 and the workpiece 1 are pushed onto the ground horizontal track 4-1 of the multi-wire cutting machine loading and unloading system, and their front and rear positions are adjusted so that the vertical roller 3-3-1 in the roller assembly 3-3 is adapted to the lifting track 4-2 of the multi-wire cutting machine loading and unloading system. Under the command of the control system, the loading and unloading vehicle 3, carrying workpiece 1, moves upward along the lifting track 4-2 of the multi-wire cutting machine's loading and unloading system. After reaching the set height, the vertical roller 3-3-1 and horizontal roller 3-3-2 in the roller assembly 3-3 are respectively adapted to the horizontal track 4-3 of the multi-wire cutting machine's loading and unloading system. Under the command of the multi-wire cutting machine's control system, the loading and unloading vehicle 3, carrying workpiece 1, runs along the horizontal track 4-3 of the multi-wire cutting machine's loading and unloading system to the material plate slide of the multi-wire cutting machine, and then enters the workpiece clamping position of the multi-wire cutting machine's swing worktable along the material plate slide, completing the workpiece loading operation. The unloading operation of workpiece 1 after cutting can be achieved by reversing the above steps. During the assembly and replacement of grooved wheels and wire wheels in the worktable swing type multi-wire cutting machine 4, the transfer problem during the assembly and replacement of wire wheels and grooved wheels can be solved by using the optional grooved wheel support plate 3-5 or wire wheel lifting device 3-6, and by cooperating with the loading and unloading vehicle 3 and the multi-wire cutting machine's loading and unloading system.
