Description

Hair clipper tool and method of manufacturing same

The invention relates to a hair clipper cutter and a manufacturing method thereof, in particular to a process for processing a thick metal sheet into a cutter, and the cutter structure produced by the utility model can improve the shearing efficiency and make the trimmed hair relatively flat. .

The blade of the hair clipper is usually composed of a stationary fixed blade and a movable blade superposed on the fixed blade, and the movable blade moves back and forth to be staggered with the fixed blade to cut the hair.

In order to achieve good shearing effect of the hair clipper blade and maintain durable and stable performance, the current technique is to use a thick metal plate material, and then cut the tooth shape with a grinding wheel to make the tooth shape have an acute angle and maintain the thickness and For the structural strength, as shown in Fig. 1A, it is a schematic view of the cutting of the cutting wheel 111a to form the cutting edge 111a, and the upper and lower cross-sectional views of the cutting edge portion 111 produced after the cutting process are as follows. 1B and 1C; and the above-mentioned complete tool for cutting the thick metal plate material with the grinding wheel 7 is shown in Fig. 2A, but the thick metal plate material is machined by the grinding wheel. The following disadvantages occur: (a) As shown in Fig. 2A, the tooth 11 and the tooth 11 have a V-shaped tooth groove 12, so as shown in Figs. 2B and 3A, when the movable blade 1 and the fixed blade are When the two-phase stack is mounted on a hair clipper 3, it can be found in FIG. 3A that since the bottom end of the V-shaped gullet 12 is narrowed, the hair entering the bottom of the V-shaped gullet 12 at the time of hair cutting is obtained. 5 will be pushed back because of the squeeze, because The trimmed hair 6 may have a lengthy phenomenon; (b) In addition, as shown in Fig. 3B, since the bottom end of the V-shaped gullet 12 is narrowed, the V-shaped cogging is entered as described above. The hair 5 at the bottom of the 12 will be squeezed, so the hair bundle will be tightly concentrated, and when shearing, the tightly concentrated hair bundle will make the shearing more laborious, so there will be a reduction in shear efficiency; c) Due to the large friction area at the bottom end, the blade is easy to heat up and burn when used; (d) The large friction area causes high power consumption; (e) The above processing method will increase the processing volume of the grinding wheel, making The life of the grinding wheel is reduced and the problem of increased processing costs occurs.

It can be seen from the above that such a tool for cutting a thick metal plate material by a grinding wheel has the above disadvantages. In order to overcome the above problems, the present invention performs a stamping process on a thick metal plate material before cutting. In order to bend the bottom end of any two teeth to form a slot, in addition to the shearing function, the slot can make the trimmed hair more flat, improve the cutting efficiency, and reduce the blade. This should be a better solution for reducing the area of the wiper, reducing the heat of the blade, reducing the power consumption and reducing the amount of grinding wheel processing.

The invention relates to a hair clipper cutter and a manufacturing method thereof, which are capable of performing a stamping process on a thick metal sheet material before cutting, thereby reducing the working hours and workload of the grinding wheel and the consumption of the grinding wheel tool. In addition to making the trimmed hair smoother, the resulting cutter can improve the cutting efficiency and reduce the problem of blade scalding.

The above-mentioned hair clipper cutter has a plurality of cutter units, and both sides of the front end of any one of the cutter unit are a blade portion, and the bottom end of either side of the cutter unit is adjacent to the adjacent one. The bottom end of the cutter unit is curved inward to form a slot.

More specifically, the blade portion has an acute angle.

More specifically, the slot is more tapered such that the bottom of the slot has an acute angle of shear function.

More specifically, the slot is a circular slot.

A method for manufacturing a tool for a hair clipper, the method comprising: (1) first stamping a stamping device to form a semi-finished blade having a plurality of circular through holes; and (2) applying a grinding wheel device to the half process Cutting the front end of the circular penetrating hole of the blade toward the circular through hole to form two corresponding blade portions, and forming a groove in the inner arc between any two corresponding blade portions hole.

More specifically, the blade portion has an acute angle.

More specifically, the slot is more tapered such that the bottom of the slot has an acute angle of shear function.

More specifically, the slot is a circular slot.

Other details, features, and advantages of the present invention will be apparent from the following description of the preferred embodiments.

Please refer to FIGS. 4, 5 and 6 , which are schematic diagrams showing the structure of the unprocessed blade of the hair clipper and the manufacturing method thereof, the schematic diagram of the blade structure of the partial processing and the schematic structure of the processed blade, which are movable in the present invention. The blade is used as an example, but the tool structure and manufacturing method disclosed in the present invention can also be used for fixing the blade. In this embodiment, the punching device (not shown) is first punched out with several circular penetrations. The movable blade 4 of the hole 411, wherein the circular through hole 411 is located on the flat surface 41 at the front end of the movable blade 4, at which time the stamped movable blade 4 is a half processing blade.

It can be seen from Fig. 5 and Fig. 6 that a grinding wheel device (not shown) is then applied to the front end portion 42 of the movable blade 4 behind the semi-processed blade toward the circular through hole 411. Cutting to form a plurality of aligned cutter units 44, the blade portion 441 on the side of the cutter unit 44 is formed by cutting the grinding wheel device, and since the grinding wheel device is cut toward the circular through hole 411, A slot 45 is formed between any two corresponding blade portions 441.

In addition, since the movable blade 4 of the semi-processing blade has a front end portion 42 at the front end and a flat surface 43 at the front end portion, the cutter unit 44 after cutting through the grinding wheel device during reworking is The top surface of the front end is also a slope 442, and the bottom surface of the front end is also a plane 443. Therefore, when the cutting is completed, the blade portion 441 naturally has an acute angle 4411. Therefore, the process of the present invention only needs to use the stamping and the grinding wheel to cut two. In addition, the slot 45 also has a taper (not shown), whether it is the acute angle 4411 of the blade portion 441 or the taper of the slot 45, when the movable blade 4 and a fixed blade are used. The clip is used to be able to cut the hair, and the taper of the slot 45 will enable the bottom of the slot 45 to be an acute angle with a shearing function.

The method for manufacturing the movable blade of the present invention, as shown in FIG. 7, is organized as follows: (1) forming a semi-processed blade 801 having a plurality of circular through holes by a punching device; and (2) Cutting at a front end of the circular penetration hole of the semi-processing blade with a grinding wheel device toward the circular penetration hole to form two corresponding blade portions, and at any two corresponding blade portions The inner arc is formed with a slot 802.

It can be seen from the above process that the manufacturing process is different from the conventional V-shaped cogging. The present invention pre-disposes the slot 45 in the bottom of the cutter unit 44, so that the cutting forming process required for forming the cutter unit 44 is produced during processing. The path is shortened, which will reduce the amount of machining for cutting and increase the machining efficiency and reduce the consumption of the grinding wheel tool.

As shown in Figs. 8A, 8B, 9A and 9B, when the movable blade 4 and the fixed blade 2 are stacked and mounted on a hair clipper 3, as shown in the figure, when the hair is cut, the following characteristics are obtained: (1) Since the slot 45 can effectively reduce the mutual squeezing state of the stuffed hair 5, the hair 5 entering the gullet at the time of hair cutting is not pushed back by the squeezing; therefore, the trimmed hair 6 is relatively flat. There will be no unevenness. (2) The hair 5 entering the slot 45 can be maintained in the original loose state, and the tight hair bundle is narrowed compared to the bottom end of the conventional V-shaped groove, so that the shearing is labor-saving, so that the shearing efficiency can be improved. (3) Comparing Fig. 8B of the present invention with Fig. 2C of the prior art, it is understood that the contact surface 444 of the present invention overlaps with the stationary blade 2, and the sawtooth tooth 11 and the fixed blade 2 of the prior art. The superposed contact faces 113 are in contrast to the conventionally shaped serrated teeth 11 being V-shaped slots 12, and the tooth unit 44 of the present invention has the slot 45 due to the slot 45. The bottom of the groove has an arc-shaped recess, so that the slot 45 of the present invention can make the contact area of the blade smaller than that of the conventional V-shaped slot 12, so that the friction resistance can be effectively reduced and the power consumption can be reduced during operation; At the same time, the temperature generated by the friction is lowered, thereby reducing the problem of blade scalding.
