Abstract

An ox horn comb is mechanically made up through sterilization, removing dirt, drying, blanking, hot pressing in a mould, punching teeth and polishing. By sequential control of temp, pressure and time during hot pressing, the OX horn comb with health-care function is flat and non-deformable.

Description

A kind of preparation method of horn comb

The present invention relates to a kind of preparation method of horn comb, this horn comb is that machining forms specifically, comprises operations such as sterilization, decontamination, blanking, shaping, punching press.

Existing horn comb shaping is many, and efficient is lower based on craft, and cost is higher, and difficult quality guarantee.

The object of the present invention is to provide a kind of preparation method of the horn comb based on machining, improved efficient, guaranteed quality, reduced cost and can produce in enormous quantities.

The preparation method of horn comb of the present invention comprises following operation successively:

1. sterilization, decontamination, drying;

Existing decontamination, sterilization method all can adopt, and just make ox horn purify, go in raw meat, the disinfecting process, avoid the distortion of ox horn raw material;

2. as required ox horn is cut into certain blank;

According to comb type to be processed, planar dimension, make model, material is got in setting-out on the ox horn raw material, certainly to consider the allowance of following operation, go out blank with machine cuts, avoid when cutting, making ox horn organize coking, thereby influence the quality of horn comb because of temperature is too high.

3. hot pressing, typing

This is a committed step, because ox horn is shown off bending, the plane is irregularity also, and warpage is arranged, in order to produce qualified horn comb, necessary shaping;

Aforementioned blank is placed in the counterdie of a special mould, during pressurization, patrix is pressed to counterdie, after closing up, the ox horn blank bears the pressure from patrix, because pressurization destroys the interior tissue of ox horn blank easily under cold state, and after shaping, stay internal stress, admittedly take to carry out shaping after the heating, be hot pressing, based on the above object, hot pressing process of the present invention, take slow intensification, reach 280-380 ℃ of constant temperature until temperature, constant voltage a period of time is according to the specification of ox horn comb, time, parameters such as temperature change to some extent, then slowly cooling, step-down, until arriving normal temperature, normal pressure, slab does not have under the state of gap at two intermodes and stays for some time, the flatness that makes it slab reaches best, and it is minimum for the each several part temperature is more reached unanimity that internal stress reduces to, and the smooth typing of hot pressing is better, also in the die cavity of putting slab, inject hot-melt object, for example high melting point paraffin.

Said process and each parameter control are carried out by computer operation all by custom-designed regulatory process.

4. above-mentioned slab is sent in the special mould, stamped out broach, be shaped.

5. with the comb deburring that is shaped, polish, wax, pack.

Explain the present invention in conjunction with the accompanying drawings.

Fig. 1 is common made in accordance with the present invention stockless horn comb.

Fig. 2 is the common made in accordance with the present invention handle horn comb that has.

Embodiment 1

The common stockless horn comb of preparation Fig. 1, long 17 centimeters of this comb, 4 centimeters of Breadth Maximums, thick 0.5 centimeter,

Get the ox horn raw material, heating decontamination, sterilization, heat medium are water, boil, go raw meat, stop 40 minutes, are cooled to normal temperature, and 40-50 ℃ of dryings of baking oven low temperature are standby; Grinding levelling to 0.5 is centimeter thick to prevent coking, cuts into the blank of 18 centimeters * 4.5 centimeters sizes, sends in the hot pressing die, places counterdie, fixing, pressurization, pressure is 10Kg/cm, slowly heats up, put into paraffin in the die cavity,, stop hour to 300 ℃, slowly cooling, step-down, to normal temperature, normal pressure, stop half an hour, slab is taken out in the demoulding, stamp out broach, deburring, is waxed, is packed at mirror finish.Embodiment 2

The common of preparation Fig. 2 has a handle horn comb, and long (handle) 13 centimeters of comb is maximum wide 3 centimeters, thick 0.3 centimeter.

Get the ox horn raw material, heating decontamination, sterilization, heat medium are water and detergent, and water accounts for 95%, and liquid detergents 5% boils, and stops 30 minutes, removes raw meat, is cooled to normal temperature, 40-50 ℃ of dryings of baking oven low temperature; Grinding levelling to 0.3 is centimeter thick slightly, prevents coking, cuts into the blank of 14 centimeters * 4 centimeters sizes, sends in the hot pressing die, place counterdie, fixing, pressurization, pressure 10Kg/cm, put into paraffin in the die cavity, slowly be warming up to 280 ℃, stopped 1 hour, slowly cooling, step-down, to normal temperature, normal pressure, stop half an hour, slab is taken out in the demoulding, stamp out broach, the unhairing tooth, is waxed, is packed at mirror finish.

Horn comb made in accordance with the present invention, owing to adopted advanced heat pressing process, make horn comb smooth smooth by controlling parameters such as temperature, pressure, time in an orderly manner, never distortion, durable in use and with health role, owing to take machining, be able to mass production, reduce cost, guaranteed the quality of horn comb.

Claims

1, a kind of preparation method of horn comb is characterized in that this horn comb forms through machining, comprises following operation successively:
