Description

Technical Field

[0001] The present invention relates to the technical field of multi-wire cutting, and particularly to a material plate locking device for a large multi-wire cutting machine. Background Art

[0002] A multi-wire cutting machine is a slicing processing equipment that grinds abrasive into the processing area of the material to be cut through the high-speed reciprocating motion of a metal wire (cutting wire), and simultaneously cuts the workpiece into hundreds or thousands of thin slices. It has the advantages of high working efficiency and less raw material loss. Before the multi-wire cutting machine equipment performs cutting operations, it is necessary to first complete the material sticking operation, that is, stick the workpiece on the material plate, and then install the workpiece on the workbench through the material plate. With the wide application of multi-wire cutting technology, the size specifications of the cut workpieces show a trend of large-scale development, and the workbench swing type multi-wire cutting equipment has emerged as the times require. As shown in the attached Figure 1 For a large cutting workpiece 1 shown in the figure, a workbench swing type multi-wire cutting machine is used to cut it. The workpiece 1 and the material plate 2 are pushed into the cutting chamber by the horizontal propulsion mechanism of the loading and unloading system, and are hoisted above the cutting wire mesh under the cooperation of the material plate clamping track 3 on the swing workbench. The front position of the material plate 2 is limited by the limiting element arranged on the workbench. To ensure the stability of the material plate 2 and the workpiece 1 during the cutting process and improve the cutting quality, it is also necessary to use a wedge locking mechanism to lock and fix the material plate locking surface 2-1 at the rear end (free end) of the material plate 2.

[0003] Currently, for ordinary swing type multi-wire cutting machine equipment, generally, a manual method is used to directly lock and fix the material plate with a wedge. However, for a large workbench swing type multi-wire cutting machine, since a material plate horizontal propulsion mechanism is configured in its loading and unloading system, not only is the operation space limited, but also according to the operating procedures requirements of the equipment, it is prohibited for operators to work under the material plate horizontal propulsion mechanism. Therefore, it is imperative to innovatively design a material plate locking device for large multi-wire cutting machine equipment. Summary of the Invention

[0004] The present invention provides a material plate locking device for a large multi-wire cutting machine, aiming to lock and fix the free end of the material plate through the cooperation of a lifting seat, a locking execution mechanism and a special tool, so as to ensure the personal safety of the operator and the stability of the workpiece cutting process, and improve the product quality.

[0005] To achieve the above object, the present invention adopts the following technical solutions: A material plate locking device for a large multi-wire cutting machine is provided with a fixed frame, a lifting seat, a locking execution mechanism and a special tool; The fixed frame is installed on the lifting body of the multi-wire cutting machine equipment, a lifting seat is assembled on the fixed frame, and a locking execution mechanism is arranged on the lifting seat; The locking actuator includes a locking wedge, a locking pressure plate, a locking bolt, a wedge bracket, and a bracket push plate; the wedge bracket is placed on the lifting seat and fixedly connected to the bracket push plate, and the wedge bracket can be pushed and pulled back and forth by the bracket push plate; the locking wedge is placed on the wedge bracket, and the front end face of the locking wedge is an inclined surface that fits with the locking surface of the material plate. An insertion groove for the material plate clamping track is provided on the locking wedge; the locking pressure plate is arranged between the wedge bracket and the locking wedge, and the central axis thereof coincides with the central axis of the insertion groove of the material plate clamping track on the locking wedge. The locking pressure plate is fixedly connected to the material plate clamping track through the locking bolt; The special tool includes a long-handled wrench and a wedge push-pull bolt. The long-handled wrench is used to screw the locking bolt, and the wedge push-pull bolt can pass through the wedge bracket and be connected to the locking wedge.

[0006] In the above-mentioned large multi-wire cutting machine material plate locking device, in the locking actuator, the wedge bracket is an L-shaped bracket, the outer side surface of its vertical wall is fixedly assembled with the bracket push plate, and a pressure plate assembly groove is provided on the inner side surface of its vertical wall. The locking pressure plate is placed in the pressure plate assembly groove of the wedge bracket.

[0007] In the above-mentioned large multi-wire cutting machine material plate locking device, a limit groove and a limit hole that cooperate with the locking actuator are provided on the bottom surface of the lifting seat; the limit groove is a rectangular groove, and the front and rear movement limit positions of the wedge bracket are defined by the front and rear edges of the rectangular groove.

[0008] In the above-mentioned large multi-wire cutting machine material plate locking device, in the locking actuator, the bracket push plate is an L-shaped push plate, which is arranged under the lifting seat, and its vertical wall passes through the limit groove on the bottom surface of the lifting seat and is fixedly assembled with the wedge bracket. Positioning holes are provided on the horizontal wall of the L-shaped push plate. Two groups of positioning holes are arranged front and rear, and the two groups of positioning holes are respectively matched with the limit holes on the bottom surface of the lifting seat through positioning pins to fix the front and rear positions of the wedge bracket.

[0012] The present invention provides a locking device for the material plate of a large multi-wire cutting machine. It can cooperate with a lifting seat and a fixed frame to realize the switching between the operating position and the non-operating position of the material plate locking operation. When the material plate and the workpiece enter the cutting chamber through the horizontal pushing mechanism of the loading and unloading system of the multi-wire cutting machine, the lifting seat drives the locking actuator to rise to a set height to avoid the passage of the material plate and the workpiece. After the material plate and the workpiece are pushed in place, the lifting seat drives the locking actuator to descend to the material plate locking operation position. First, the inclined iron bracket is pushed to a set position through the bracket push plate, and then the locking inclined iron is pushed to the position where it fits the material plate locking surface through the inclined iron push-pull bolt. Then, a long-handled wrench is used to screw the locking bolt, and the locking inclined iron inclined surface and the material plate locking surface are pressed and fixed through the locking pressing plate. Thus, the free end of the material plate is locked and fixed by operating remotely outside the cutting chamber of the multi-wire cutting machine, achieving the purpose of ensuring the personal safety of the operator and the stability of the workpiece cutting process and improving the product quality.
