Description
Technical Field
The utility model relates to a mould processing field especially relates to a wire cutting device is used in mould processing.
Background
The wire cutting, also called wire electrical discharge machining, the working principle of the wire cutting is to use the wire electrode as the tool electrode, under the action of the pulse power supply, namely one pole of the pulse power supply is connected with the workpiece, the other pole of the pulse power supply is connected with the wire electrode, through the discharge of the pulse power supply, the spark discharge is formed between the tool electrode and the workpiece, and the emitted spark generates a large amount of heat instantly, so that the surface of the workpiece is melted or vaporized, and the cutting of the workpiece is completed.
The parts of the notebook computer need to be formed in a mold, for example, the housing of the notebook computer needs to be formed by stamping in the mold, so that the housing of the notebook computer has a convex edge. Be adapted to and be equipped with four vertical fixed slots that set up on the mould of notebook computer shell usually to be convenient for fix the mould to the punching press bench. The fixed slot on the mould is mostly formed through the processing of wire-electrode cutting mode, when carrying out the wire-electrode cutting to the mould, needs fix a position the mould, avoids the mould to remove to make more accurate among the wire-electrode cutting process. However, when the mold is positioned, the four clamping blocks are required to clamp four sides of the mold respectively, and when the clamping blocks are used for clamping the mold at each time, different clamping blocks are required to be operated manually in sequence, so that each clamping block is loosened or clamped in sequence, the operation is troublesome, and the positioning speed of the mold is slow.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a wire cutting device is used in mould processing to the realization is tight to the quick location clamp of mould.
In order to achieve the above purpose, the technical scheme of the utility model is that: a linear cutting device for die machining comprises a clamping table, wherein four clamping mechanisms are arranged on the clamping table, each clamping mechanism comprises a fixed block fixedly connected to the clamping table and a clamping block slidably connected to the clamping table, and an elastic part is connected between each clamping block and the corresponding fixed block; the vertical removal in below of centre gripping platform has the step board, is connected with the piece that resets on the step board, is connected with link gear between step board and the grip block.
The working principle of the scheme is as follows: the clamping mechanism is used for clamping a wire cutting die. The linkage mechanism is used for driving the clamping block to slide on the clamping table. Before the mould is put on fixture, through acting on the pedal with the foot, vertical displacement takes place for the pedal, and the pedal makes the piece that resets produce deformation and hold power. The pedal drives the clamping blocks on the four clamping mechanisms to move towards the fixed block on the clamping table through the linkage mechanism, so that the four clamping blocks are opened, the mold is conveniently placed between the clamping blocks, and meanwhile, the clamping blocks also enable the elastic piece to deform to store force. After the mold is placed between the clamping blocks, the pedal is released, the pedal resets under the action of the resetting piece, meanwhile, the action of the pedal on the linkage mechanism disappears, and the clamping blocks reset under the action of the elastic piece to be close to the mold, so that the mold is automatically clamped. After the grip block cliied the mould, the elastic component can provide certain pressure for the grip block to the centre gripping of mould, so the elastic component in this scheme not only can make the grip block reset and be close to the mould to still can provide certain clamping-force, make the mould centre gripping more stable.
When the technical scheme is adopted, the pedal is trampled, so that four clamping mechanisms can be controlled simultaneously, clamping blocks on the four clamping mechanisms are automatically opened simultaneously, the clamping blocks on the four clamping mechanisms are not required to be manually opened one by one, the operation is simple and convenient, and the opening speed of the clamping blocks is improved. When the pedal is not trampled, the clamping blocks on the four clamping mechanisms automatically reset to clamp the die, manual operation is not needed to reset the clamping blocks one by one, and resetting is rapid.
