Background

At present, the requirement of customers on the smoothness and the groove shape of a guide wheel product is higher and higher, the detection means of the appearance of the guide wheel is gradually mature, for example, the groove shape is detected by projection type detection equipment, and once impurities exist in the groove shape, the accuracy of a detection result is influenced even by very fine dust. In addition, from the use condition of an end customer, the groove shape and the smoothness greatly influence the position stability of the cutting steel wire in the groove, and further influence the yield of the product of the customer. Once the guide wheel cutting yield is not good, the customer can change the corresponding guide wheel, and the smooth finish in the groove can influence the life-span of the guide wheel.

The analysis is carried out on the grooving process, the degree of finish in the guide wheel groove is determined by the quality of the cutter to a great extent, the existing grooving cutter is basically made of PCD (artificial polycrystalline diamond), the diamond cutter has good abrasive resistance, but when soft polyurethane is cut, the problem of wire winding is easy to occur, once the wire winding problem occurs, the cutter point can generate the friction overheating problem due to the fact that a cooling water path is blocked, the diamond tip is easy to damage, and the problem of cutter point falling even occurs in serious conditions, which is the main problem of influencing the grooving shape and the degree of finish.

Therefore, how to avoid the problem of wire winding of the tool nose is the key point of improving the smoothness in the groove, the traditional method is to reduce the feeding speed of the groove, so that the wire can be changed into powder, but the efficiency is low, in addition, the powder is remained in the groove, and the cutting problem can be caused if the cleaning is not clean.

Detailed Description

The present invention will now be further described with reference to the accompanying drawings.

As shown in fig. 1 to 6, a slotting cutter comprises a cutter handle 1, wherein one end of the cutter handle 1 is provided with a fixing groove 15, the bottom of the fixing groove 15 is provided with a water spraying hole 14, the other end of the cutter handle 1 is provided with a water inlet 12, the water inlet 12 is communicated with the water spraying hole 14, one side of the cutter handle 1 is provided with a water inlet 11, and the water inlet 11 is communicated with the water inlet 12; the tool bit 2 is fixed in the fixing groove 15 and is positioned below the water spraying hole 14, and the water spraying hole 14 is used for spraying cooling liquid to the tool bit 2 and/or the tool tip.

Set up the cooling water route on handle of a knife 1, thereby directly spray cooling to tool bit 2 and knife tip and make tool bit 2 and knife tip obtain lasting, reliable cooling, effectively solved the overheated impaired condition that leads to the diamond point end of friction to guarantee the smooth finish in the product groove, improved the quality of product, and the cutting that can be stable for a long time, improved machining efficiency greatly, reduced the processing cost.

The end of the water inlet 12 is provided with a sealing screw hole 13, and the plug is arranged on the sealing screw hole 13.

In at least one embodiment, the water spray holes 14 are arranged in parallel with the tool bit 2 and spray a cooling liquid along the surface of the tool bit 2. The water spraying holes 14 spray cooling liquid along the surface of the tool bit 2, so that the tool bit 2 and the tool nose are both covered by the cooling liquid to be sprayed, and the cooling effect is effectively improved.

In at least one embodiment, the bottom of the fixing groove 15 is provided with a countersunk hole 16, and the tool bit 2 is provided with a threaded hole 21; and also includes a screw which is mounted in the countersunk hole 16 and is connected with the threaded hole 21. The screw-fixed tool bit 2 is simple in structure, the tool bit 2 is convenient to replace, and the tool shank 1 does not need to be replaced.

In at least one embodiment, the angle of the front angle A of the cutter head 2 is 10-45 degrees. The larger the rake angle, the sharper it. Because the soft polyurethane is cut and the forming cutter is used for processing, and the processed groove is a V-shaped groove, both sides of the cutter point are main cutting edges. The cutter handle 1 is horizontally arranged, the front angle of the cutter head 2 is 10-45 degrees, the front angle enables a cutting edge to be sharp, cutting chips are reduced, cutting force is small, cutting is light and fast, cutting quality can be guaranteed, cutting efficiency is improved simultaneously, and wire winding can be effectively avoided.

The water spraying holes 14 are small holes, so that the lift of water spraying can be ensured, and the tool bit 2 and the tool tip are both covered by cooling liquid.

For solving the problem of wire winding, a corresponding solution is found from the spray mode of the cutter point cooling liquid through analysis: the cutter used in the prior art is an integrated cutter, and cooling liquid is sprayed to a cutter point by spraying an original nozzle of equipment; the distance between the nozzle and the tool nose is long, the spraying effect is dispersed, and the spraying direction needs to be repeatedly adjusted by workers; no matter which factor goes wrong, the spraying effect is poor, and the grooving quality is affected.

In order to solve the three problems, the structure of the handle 1 of the slotting cutter is redesigned, the handle 1 is hollow, one end of the handle is made into 1/4 pipe threads, the position, close to the cutter point, of the handle 1 is provided with a water spraying hole 14, the water spraying hole 14 is a small hole, the water spraying hole 14 is connected with the position of an original nozzle through a hose in use, and when the cutter is used by equipment, cooling liquid can be automatically guided to the cutter point position through a cutter tower, the hose and the handle 1 to cool the cutter point.

The cutter is convenient to install, the water spraying distance is shortened, the manual adjustment of the spraying direction by workers is not needed, the strength of water spraying is controlled by the size of the hole at the cutter tip, the problem of water spraying dispersion is thoroughly solved, and the defects of the conventional cutter are perfectly overcome.

Through verification, after the guide wheel is grooved, no debris is left in the groove, the groove shape performance is better, and the smoothness is greatly improved.

The technical principle of the present invention is described above with reference to specific embodiments. The description is made for the purpose of illustrating the principles of the invention and should not be construed in any way as limiting the scope of the invention. Based on the explanations herein, those skilled in the art will be able to conceive of other embodiments of the present invention without any inventive effort, which would fall within the scope of the claims of the present invention.
