Abstract
Description
Technical Field
[0001] This utility model relates to the field of multi-wire cutting technology, specifically to a material-adhesive tooling for multi-wire cutting of large workpieces. 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 multi-wire EDM machines can perform cutting operations, a material bonding process must be completed. In existing technology, this typically involves placing the workpiece flat on a platform and directly attaching it to the workpiece. However, with the widespread application of multi-wire EDM technology, the size of the workpieces being cut is trending towards larger dimensions, as shown in the attached image. Figure 1 The large workpiece 1 shown is typically transported from the bonding station to the multi-wire cutting loading station using a crane in the workshop due to its weight. It is then cut using a swaying multi-wire cutting machine. During the cutting operation, the workpiece is suspended on the swaying worktable, so its bonding surface is located on the upper end of the workpiece. A marble slab 3 is placed between the workpiece 1 and the material plate 2. According to the bonding process specifications, the marble slab 3 must first be bonded to the upper end of the workpiece 1, and then the marble slab 3 is bonded to the material plate 2. To ensure the stability of the workpiece, the accuracy of the material plate bonding position, and improve work efficiency during the above operation, an innovative design of the bonding fixture is required. Utility Model Content
[0004] This utility model provides a material bonding fixture for multi-wire cutting of large workpieces. It aims to achieve accurate positioning of large workpieces and material plates by using a material bonding platform, side positioning column assembly, and limit bolts, thereby ensuring the bonding quality of the workpieces and improving work efficiency.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A material-adhesive fixture for multi-wire cutting of large workpieces includes a material-adhesive platform, a side positioning column assembly, and limiting bolts. The material-adhesive platform is horizontally arranged, and the side positioning column assembly is fixedly assembled on the platform. The side positioning column assembly comprises two parts arranged front and rear, with several sets of side positioning columns arranged in parallel in each part. Several threaded holes are provided on the side positioning columns along the vertical direction. The limiting bolts are fitted with the threaded holes on the side positioning columns, and the positioning of the workpiece and the side of the material plate is achieved through the several limiting bolts arranged vertically.
[0007] The aforementioned adhesive tooling for multi-wire cutting of large workpieces includes an adhesive platform with longitudinal beams and transverse beams. There are three sets of longitudinal beams, and the transverse beams are mounted on top of the longitudinal beams. The transverse beams are fixedly assembled with the longitudinal beams, and a gap L is reserved between two adjacent sets of transverse beams.
[0008] The aforementioned adhesive tooling for multi-wire cutting of large workpieces has protective lining plates installed on the middle part of the upper end face of the crossbeam and on the inner side wall of the side positioning column. The protective lining plates are fixed to the crossbeam or the side positioning column by adhesive bonding.
[0009] The aforementioned adhesive tooling for multi-wire cutting of large workpieces includes a side positioning column with a base. The side positioning column is fixedly connected to both ends of the crossbeam via the base. An inclined brace is provided on the outside of the side positioning column. The inclined brace has two right-angled sides, which are fixedly connected to the vertical surface of the side positioning column and the base, respectively.
[0010] The aforementioned adhesive tooling for multi-wire cutting of large workpieces has movable casters at both ends of the longitudinal beam of the adhesive platform, and the movable casters are rollers with a braking structure.
[0011] This invention provides a material-adhesive fixture for multi-wire cutting of large workpieces. It supports the workpiece via a material-adhesive platform, and then the workpiece and the sides of the material plate are tightened and fixed by limiting bolts mounted on the side positioning columns. Because several threaded holes are provided vertically on the side positioning columns, the installation position of the limiting bolts can be flexibly adjusted according to the size of the workpiece to match different sizes and specifications of workpieces to be cut. In this invention, the material-adhesive platform adopts a longitudinal beam and transverse beam connection structure, with the transverse beams mounted on top of the longitudinal beams. A pre-reserved interval L is provided between adjacent sets of transverse beams. This not only reduces the weight of the material-adhesive platform but also allows for the passage of safety ropes for workpiece hoisting through the pre-reserved interval L between adjacent sets of transverse beams, ensuring the safety of the workpiece during hoisting. This invention also provides protective lining plates on the middle part of the upper end face of the transverse beams and on the inner wall of the side positioning columns to prevent damage caused by collisions between the workpiece and the material-adhesive fixture during workpiece hoisting. This invention features movable casters at both ends of the longitudinal beam of the material-adhesive platform. These casters allow it to be used in conjunction with multi-wire cutting equipment placed in different areas, thereby reducing equipment investment costs. Attached Figure Description

During the cutting operation, the workpiece 1 is suspended on the swing workbench, so the bonding surface between it and the material plate 2 is located on the upper end of the workpiece 1. A marble plate 3 is placed between the workpiece 1 and the material plate 2. According to the bonding operation process specifications, the marble plate 3 must first be bonded to the upper end of the workpiece 1, and then the marble plate 3 is bonded to the material plate 2.
