Description

Improved extrusion

The present invention relates to a cutting tool in the field of cutting, and more particularly to a pressing member for use in a turning tool.

In the field of cutting, a turning tool (frame) is commonly used for cutting an inner circumferential surface, an outer circumferential surface or an end surface of a workpiece.

The turning tool (frame) disclosed in Taiwan Patent No. 301261, presses a blade with a plate that is locked to the turning tool (frame), and allows the blade to be placed in the turning tool (frame) to prevent the blade from being shocked and leaving the car. Knife (frame).

The pad is long and narrow, one end of which is in contact with the blade, and the other end is passed by a screw that is locked to the turning tool (frame). Since there is no cooling passage inside the turning tool (frame), the pressing plate has no room for the flow path arrangement. Therefore, during the cutting of the workpiece, the cooling pipe is sprayed from the outside to the cutting portion of the blade to the workpiece to lower the cutting temperature. The cooling tube is flexed and can be manually pulled up to the blade and adjusted in angle to determine the spray position of the coolant.

During the cutting, the cooling tube changes the nozzle angle due to vibration, so that the coolant cannot be sprayed to the correct position. Therefore, the angle of the cooling pipe must be manually adjusted from time to time, and there is no need to use it.

In order to enable the cutting operation to be carried out smoothly, the inventor of the present invention proposed a gripper, and the invention patent application No. 106133481 was filed by the bureau.

The inventor of the present case is not complacent, and continues to research and develop in related fields. One of the main purposes of improving the aforementioned invention patent application is to use a new pressing member to be more stably assembled on the turning tool.

One of the main purposes of the improved pressing member of the present invention is to change the flow path outlet of the pressing member by means of adjustment, and can adapt to different blades to obtain the correct injection angle and position of the cooling liquid.

For the above object, the pressing member of the present invention comprises: a body having a first end and a bottom surface; an extending portion, a pad and a pressing portion, the three protruding from the bottom surface of the body; Straight from the extension to the first end of the body; and a coupling hole extending through the bottom surface of the body, the coupling hole being between the extension, the spacer and the pressing portion.

When the pressing member is assembled in a turning tool, the coupling hole is passed by a fastener fastened to the turning tool, and the sliding block and the bottom surface of the pressing portion supporting body are separated from the turning surface, and the extending portion is connected to a cooling formed inside the turning tool aisle.

The body also has a second end, and a protrusion is formed from the second end to a single side of the body. The pressing portion is adjacent to the first end of the body, the extending portion and the spacer being adjacent to the second end of the body, the spacer being adjacent to the convex portion and the bottom surface. Wherein, the pressing portion is at the center of the large diameter portion, and the large diameter portion protrudes from the bottom surface of the body, which is on the same horizontal line as the spacer, and the horizontal line is separated from the bottom surface of the body by a distance.

Additionally, the flow passage is considered to be an inlet through one end of the extension, the flow passage having a plurality of outlets at the first end of the body. When the press member is assembled to the turning tool, the flow path alone leaves a single outlet and blocks the remaining outlets, directing the coolant to a blade tip disposed at the turning tool, or a metal scrap generated by the cutting of the workpiece by the blade.

Thus, the pressing member of the present invention adopts an extending portion, a spacer and a pressing portion to form a triangular effective pressing space, so that the pressing member can be more stably assembled on the turning tool. At the same time, one of the multiple outlets is the existing design of the flow channel, and the other outlets are made by means of adjustment (for example, according to the set value, the automatic design orientation, depth or angle of the computer lathe, the milling machine), and the outlet of the flow channel is changed. The pressing piece can be adapted to different blades to obtain the correct spray angle and position of the coolant.

The above described objects, features, features and advantages of the present invention will become more apparent and understood.

5 and 6 are schematic views of a second embodiment of the press member of the present invention, which is mounted on a turning tool for different blades.

In Figs. 1 to 4, the specific structure of the first embodiment of the press member is drawn, and the press member is mounted in a use state of the turning tool 40.

From a structural point of view, the pressing member has a body 10, and the first end 11, a second end 12 and a bottom surface 14 of the body 10 form a convex shape from the second end 12 to the single side 13 of the body 10. Department 20. Extending an extension 15, a spacer 24 and a pressing portion 26 on the bottom surface 14 of the body 10 allows the first runner 30 to pass straight from the extension 15 to the first end 11 of the body 10. In addition, the body 10 further has a coupling hole 22 between the extending portion 15, the spacer 24 and the pressing portion 26, which runs through from top to bottom. Body 10 to bottom surface 14.

In the figure, the pressing portion 26 is adjacent to the first end 11 of the body 10, and the extension portion 15 and the spacer 24 are adjacent to the second end 12 of the body 10. Wherein, the spacer 24 is adjacent to the protrusion 20 and the bottom surface 14.

In further detail, the pressing portion 26 is at the center of the large diameter portion 261 which protrudes from the bottom surface 14 of the body 10 on the same virtual horizontal line 262 as the spacer 24, the horizontal line 262 to the bottom surface 14 of the body 10. A distance of 263. In other words, the large diameter portion 261 is substantially equal to the height of the spacer 24.

Next, the flow path 30 is regarded as the inlet 31 through the end of the extension portion 15. In the present embodiment, there are two outlets 32, 321 of the flow passage 30, and the outlets 32, 321 are all at the first end 11 of the body 10. Wherein, the outlet 32 is a design of the flow channel 30, and the other outlets 321 are produced by adjusting the calibration means, such as automatically setting the orientation, depth or angle on the computer lathe and the milling machine according to the set value.

When the press member is assembled to the turning tool 40, the engaging hole 22 is passed by a fastener 28 that is secured to the turning tool 40. At this point, the spacer 24 and the pressing portion 26 support the bottom surface 14 of the body 10 away from the surface of the turning tool 40. Since the extending portion 15, the spacer 24 and the pressing portion 26 constitute a triangular effective pressing space 21, and the coupling hole 22 is dropped in the range of the effective pressing space 21, the pressing member is more stable on the turning tool 40. Further, the extension portion 15 is connected to a cooling passage 42 formed inside the turning tool 40. The extension portion 15 defines a dimple 16 that allows one or more of the water stop gaskets 17 to be tightened in the corresponding grooves 16 to achieve an anti-overflow or leak-stop effect.

Of course, the flow channel 30 alone leaves a single outlet 321 and blocks the remaining outlets 32, so that the coolant 48 can be directed to a blade tip 46 disposed at the blade 40 of the turning tool 40, or a workpiece can be tipped by the blade 44. 46 cutting metal chips (not shown). Because the position of the outlets 32, 321 of the flow passage 30 changes, the pressed member can be adapted to different blades 441 or 442 (see Figures 5 and 6). The correct injection angle and position of the coolant 48 is obtained.

Figures 5 and 6 depict a second embodiment of the extrusion which is substantially identical in construction to the first embodiment, with the difference that the projections 20 change position. Briefly, the projection 20 moves from the left side to the right side of the body 100.
