The present invention relates to a V-groove machine for bending a metal plate for processing a V-groove at a bending part so that the material is easily bent when bending at right angles to a material such as a thick steel sheet or steel sheet.

When bending thick steel plates or steel sheets, they cause cracks on the outer circumferential surface of the bent portion due to the elongation and displacement of the material depending on the thickness of the steel sheet, as well as not bending at right angles due to the elastic force of the material. By doing this, you must machine the V-groove on the bent part and perform the bending work.

Due to the above reasons, when bending a material such as a metal plate, a variety of machines for processing the V-grooves on the bent portion have been developed and used, but the V-groove machine developed so far is shown in FIG. The chain 4a is formed by the chain 4a so that the tool post 3 having the bed 2 formed on the upper surface and the cutting tool 3a set on the bed 2 is movable in the left and right y directions. It is installed so as to move in the x-axis direction (processing direction) so that the cutting tool 3a set on the tool stand 3 can process the V groove on the workpiece set on the upper surface of the bed 2 while the feed stand 4 moves. In the above-described configuration, not only accurate positioning was difficult because it was a manual type that operated the left and right y-axis feed and the up-and-down z-axis feed of the tool post 3 installed on the feed table 4 as the handle 4b. , With clamper 5 for fixing the workpiece to the bed 2 As shown in FIG. 2, the press plate 7 supported by the spring 6 is configured to press the workpiece by directly receiving the press pressure of the cylinder 8, and then operate the manual air valve to supply the oil pressure supplied to the cylinder 8. When the workability decreases and the abnormality occurs in the hydraulic pneumatic line during the clamping operation, the clamping force is released and not only the work defect is generated, but also the wire wiring necessary for the conveying operation of the tool bar is exposed to the outside, resulting in poor appearance. Since the cutting tool 3a set on the base 3 is operated by friction on the machining surface when it feeds back to the workpiece after the V groove is machined, the groove is cut in the machining part or the ratio of the cutting tool 3a is high. There were many problems with.

The present invention, in consideration of the above-mentioned conventional defects, so that the x-axis feed of the tool bar is made by the rack and pinion, and the feed motion in the y-axis direction is also coupled to the lead screw driven by the motor with a ball bearing for accurate operation. The clamper, which moves in the y-axis direction together with the tool post, clamps the end of the workpiece so that there is no flow of the workpiece during the machining operation, and there is no friction of the tool during the feedback movement of the feeder. Its purpose is to improve work efficiency and precision and to extend the service life of the machine.

It consists of a known conveyance table 50 equipped with a tool post 40 which is conveyed in the x-axis direction of the machining direction by the means and moved in the left and right y-direction, wherein the side clamper 20 is shown in FIG. As described above, when the end of the piston rod 26 of the hydraulic pneumatic cylinder 25 mounted on the lower end of the support jaw 12 of the bed 11 pushes the rear end of the side clamper 20, the bent portion 20a of the front end is processed. ) And the processing direction feed means are also shown in FIGS. 4 and 5 Drive shaft 52, timing belt 53, and drive force of the single motor 51 installed in the center of the transfer table 50 by combining the rack gear 15 at the lower sides of the bed 11 are installed. A pair of pinions 55 which are rotated by the gear 54 and the like are engaged with the rack gears 15 formed on both lower sides of the bed 11 so that the transfer table 50 moves.

In addition, the front clamper 30, as shown in Figure 6 to 8 of the accompanying drawings, a pair of clamp arms 32 coupled to the hinge 31 at regular intervals is coupled to the upper surface of the body 10 LM When the wedge 34, which is moved forward and backward along the guide 36 and moved forward and backward by the cylinder 33, raises the rear end of the clamp arm 32, the front end is the workpiece 100. Clamp

In addition, the tool post 40 is installed in the feed table 50, as shown in Figure 9 attached to the ball screw 42 is rotated by the drive of the motor 41, the left and right move and set As shown in FIG. 10, the displacement amount of the cutting tool 60 is configured to be represented by the dial gauge 43, and at the same time, the tool holder 44 is coupled to the hinge 45 so that the cylinder shown in FIG. The cutting tool 60 set at a lower end by being rotated at an angle by the operation of 46 is configured to short-circuit the processing surface of the workpiece, and the tool holder 44 forms an inclined surface 65a in the fixing recess 44a. The fixing block 65 is coupled to the fixing bolt 66, and the inclined surface 65a of the fixing block 65 is coupled to the inclined surface 60a formed on the bag of the cutting tool 60, thereby cutting the cutting tool 60. Configure to set.

Referring to the operation and effect of the present invention having the above configuration is as follows.

First, the material to be bent, such as iron plate or steel sheet is seated on the bed 11 of the present invention, one side of the processing direction to be in close contact with the support jaw (12).

As described above, the side clamper which is operated by pushing the workpiece 100 placed in the bed 11 so that one side of the machining direction is in close contact with the support jaw 12 at the end of the piston rod 26 by the operation of the cylinder 25 ( 20) The tip is clamped in place.

In this way, when the fixing of the workpiece 100 is completed, the servo motor 41 is driven to transfer the tool post 40 to the V groove machining position. In this case, the servo motor 41 is moved to the left and right y-axis directions along the LM guide 36. The pair of tip clampers 30 move together with the tool post 40 inserted therebetween, and the tool holder 44 of the tool post 40 hinges by moving the piston 47 by the operation of the cylinder 46. The cutting tool 60, which is rotated about the 45, is set at the lower end to maintain the state away from the workpiece 100 surface.

When the tool post 40 reaches the V groove machining position of the workpiece 100 in the above-described operation, the wedge 34 is advanced by the operation of the cylinder 33 and coupled to the rear end of the clamp arm 32, thereby leading to the front clamper 30. When the piston rod 47 is retracted by the operation of the cylinder 46 while simultaneously clamping both ends of the V groove machining position of the workpiece 100, the tool holder 44 is moved by the spring 48 to hold the tool holder 44. Cutting tool 60 is set at the bottom of the) is in close contact with the upper surface of the workpiece 100 is ready to process the V groove.

At this time, by rotating the handle 49 to set the height of the cutting tool 60 to determine the depth of the V groove to be processed, the vertical displacement of the cutting tool 60 is displayed on the dial gauge 43.

When the depth of machining is adjusted in the above manner, the V groove is ready for machining.
