Abstract
The utility model discloses a composite conducting block, which is characterized by comprising an inner cylinder and an outer cylinder with upper and lower ends being leveled to and connected with each other, wherein the inner wall of the inner cylinder is provided with an installation thread, the projection of the outer edge of the outer cylinder in the axial direction presents in a shape with a plurality of plum blossoms; as the further improvement of the utility mode, the inner cylinder is made of copper, and the outer cylinder is made of hard alloy. The composite conducting block has the advantages of long service life and good conductivity.
Description
Technical field
The utility model relates to a kind of conducting block that is used for to-and-fro wire-travelling type electric spark linear cutting machine.
Background technology
To-and-fro wire-travelling type electric spark linear cutting machine is the original creation technology of China, and in the use, high frequency pulse power supply inserts conducting block by lead, and reciprocating wire electrode contacts with conducting block, realizes giving wire electrode; At present in the electric spark linear cutting machine of each manufacturers produce, conducting block uses the hard alloy blocks of a die casting sinter molding mostly, shape has square or oval, and shortcoming is: 1.. because wire electrode friction back and forth can have been ground groove on the conducting block, and easy pinch off wire electrode, the user runs into this situation and only changes an intact end face use, one conducting block can change face at most 2 times, and service life is short, has improved processing cost; For 2.. just solve wear-resisting problem thereby select Hardmetal materials, with respect to copper material, its electric conductivity is relatively poor.
The utility model content
The purpose of this utility model is the above-mentioned deficiency at prior art, and a kind of composite conducting piece is provided, and it has long service life, better conductivity advantage.
For achieving the above object, composite conducting piece of the present utility model is characterized in that it comprises that both ends of the surface flush and continuous inside and outside tube up and down, and the inwall of inner core is provided with the installation screw thread, and the outer rim of urceolus is the plum blossom shape of several lobe symmetries in its axial projection;
During use, the installation screw thread by inner core is loaded on conducting block on the mandrel, in the groove between the adjacent two plum blossom lobes of conducting block sidewall an anti-rotation push rod is set, and wire electrode contacts and be positioned at the top of one group of symmetry plum blossom lobe with the upper surface of conducting block; When using a period of time at the upper surface of conducting block formation groove, can unclamp the anti-rotation push rod rotates to an angle conducting block, wire electrode is contacted with the upper surface of conducting block and be positioned at the top that another organizes symmetrical plum blossom lobe, so the upper surface of conducting block can be used repeatedly, significant prolongation service life, reduced processing cost;
As further improvement of the utility model, described inner core is copper, and urceolus is a carbide alloy; Can improve the electric conductivity of conducting block;
In sum, the utlity model has long service life, better conductivity advantage.
Description of drawings
Fig. 1 is the front view of the utility model user mode.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing to further detailed explanation of the utility model.
By illustrated in figures 1 and 2, this composite conducting piece comprises that both ends of the surface flush and continuous inner core 1, urceolus 2 up and down, and described inner core 1 is copper, and urceolus 2 is a carbide alloy, the inwall of inner core 1 is provided with the installation screw thread, and the outer rim of urceolus 2 is the plum blossom shape of 12 lobe symmetries in its axial projection;
During use, the installation screw thread by inner core 1 is loaded on conducting block on the mandrel, in the groove between the adjacent two plum blossom lobes of conducting block sidewall an anti-rotation push rod 3 is set, and wire electrode 4 contacts and be positioned at the top of one group of symmetry plum blossom lobe with the upper surface of conducting block; When using after a period of time when forming groove in the upper surface of conducting block, can unclamp anti-rotation push rod 3 rotates to an angle conducting block, wire electrode 4 is contacted with the upper surface of conducting block and be positioned at the top that another organizes symmetrical plum blossom lobe, so the upper surface of conducting block can be used six times, prolong five times service life, reduced processing cost.
Claims (2)
