Description

Technical Field

[0001] The invention relates to the technical field of cutting machine tools, in particular to a gantry type wire cutting machine tool. Background Art

[0002] Wire cutting machine tools belong to the category of electrical processing. Its basic physical principle is that free positive ions and electrons accumulate in the field and quickly form an ionized conductive channel. The Chinese invention patent with publication number CN117900577B discloses a gantry-type wire cutting machine tool. By providing a lifting mechanism, the lifting mechanism can automatically support the waste blocks generated after the workpiece is cut, without the need for the staff to manually operate through tools, effectively preventing the waste blocks from falling and causing damage to the cutting wire, which not only improves the cutting efficiency of the machine tool, but also provides safety protection for the staff; by designing a gantry mechanism, a wire storage mechanism, a threading mechanism, a fixture assembly, a pulse power supply assembly and a cooling and flushing mechanism, the machine tool can perform high-precision cutting processing on the workpiece in any direction. At the same time, when installing the workpiece, the fixture assembly can be adjusted according to the size of the workpiece to increase the clamping range. When cutting the workpiece, it can be quickly cooled and flushed through the cooling and flushing mechanism, which can not only improve the service life of the cutting wire, but also improve the cutting accuracy of the workpiece.

[0003] In the related technology, the existing wire cutting machine tools have certain defects when performing wire cutting processing on workpieces. For example, the cutting height is fixed and cannot be adjusted, and usually only wire cutting can be performed on workpieces within a specified range of sizes; when the workpiece is larger, wire cutting cannot be performed, such as tubular workpieces; and when the cutting height changes, the tension of the cutting wire will become stretched or loose, requiring the staff to re-position the cutting wire, and lacks the function of automatic adjustment, which increases the complexity of operation.

[0047] The driving member 11 is provided to cause the sliding frame 8 to move horizontally to the left and right, and the workpiece 2 can be driven horizontally through the fastener 10. A reciprocating member for longitudinally reciprocatingly driving the U-shaped frame 9 is provided inside the sliding frame 8, so that the workpiece 2 can be driven longitudinally through the fastener 10 through the driving of the reciprocating member, thereby facilitating the cutting of different trajectory lines of the workpiece 2 through the cutting mechanism.

[0048] See attached Figure 6 The wire storage member 5 includes a connecting plate 52 fixed to one side of the fixing frame 4, a U-shaped frame 53 is fixedly connected to one side of the connecting plate 52, and a winding roller 54 is rotatably connected to the inside of the U-shaped frame 53, and a motor 55 for rotating and driving the winding roller 54 is fixedly connected to the back of the U-shaped frame 53;

[0062] The workpiece 2 can be fastened by the movement of the two L-shaped clamping blocks 101 in relative directions. The bottom of the workpiece 2 can be partially supported by the setting of the telescopic frame 102. The two telescopic plates 103 are slidably connected to the inside of the telescopic frame 102, so that the two L-shaped clamping blocks 101 can be expanded or retracted for clamping.

[0063] The two telescopic plates 103 are connected to the two L-shaped clamping blocks 101 in a sliding manner, so that when the wire is cut, the driving column 107 on the lower template 73 can push the telescopic frame 102, thereby preventing the existence of the telescopic frame 102 from affecting the trajectory of the wire cutting. In addition, the inner sides of the two L-shaped clamping blocks 101 are provided with second springs 104 for elastically squeezing the telescopic plates 103, so that when the wire cutting is reset, the telescopic frame 102 can simultaneously support the cut hollowed-out waste to prevent the waste from falling and causing the wire to break, and has a good protective function.

The relative movement of the two L-shaped clamping blocks 101 can clamp the workpiece 2 between them to ensure the stability and accuracy of its wire cutting, and it has the function of centering clamping, which solves the problem that the fastening mechanism in the prior art usually uses multiple sets of clamping parts to drive when fastening the workpiece 2, which is not only too cumbersome to operate, but also unable to synchronously center the workpiece 2, affecting the processing accuracy of the workpiece 2.

[0068] The electric cylinder 111 is provided to drive one end of the driving rod 112 up and down, and the other end of the driving rod 112 is hinged to one side of the sliding frame 8, so that when one end of the driving rod 112 moves up and down, the sliding frame 8 can be synchronously driven to move left and right, and then the workpiece 2 can be driven laterally through the fastener 10. A reciprocating member for longitudinally reciprocatingly driving the U-shaped frame 9 is provided inside the sliding frame 8, so that the workpiece 2 can be driven longitudinally through the fastener 10 through the drive of the reciprocating member, thereby facilitating the electric spark cutting of different trajectories of the workpiece 2 through the cutting mechanism.
