Abstract
The invention relates to a copper pen head with full needle tube and the processing technique thereof, solving the disadvantage in the prior art that stainless steel is used to make pen head, which increases the material cost and leads to difficult processing. The processing steps is as follows: 1.1 selecting a copper cylinder and cutting the cylinder into a length of the pen head; 1.2 clamping the cut copper cylinder firmly on a lathe and drilling hole on the cylinder by a drill needle with appropriate diameter and profile. 1.3 processing an internal treatment at one end of the copper cylinder and producing a hole concave cavity for placing a rolling ball; 1.4 putting the rolling ball into the processed hole concave cavity and fixing the rolling ball by closing the hole . Adopting the copper cylinder as the pen head can save material cost, the cost can be saved by 30% comparing with the stainless steel pen head; the hardness of copper is lower than that of stainless steel, and can suffice the writing requirements; the processing of copper is easier than processing of stainless steel; and the processing cost is reduced and the processing efficiency is increased.
Description
Technical field
The present invention relates to a kind of nib and processing technology thereof, especially a kind of copper full needle-tube pen-point and processing technology thereof.
Background technology
The advantage of fountain pen and ball pen because gel ink pen is held concurrently, therefore fluent writing quite is subjected to liking of people.The pen core of gel ink pen adopts stainless steel nib, ball and the plastics shaft of a writing brush more on the market now, and the size of stainless steel nib is divided multiple model, and particularly written size is less, and the diameter of ball generally adopts the needle tube type nib when the 0.5mm left and right sides.The notification number of bulletin was a the patent that is called the neutral nib of full needle tubing of CN2799263Y such as on July 26th, 2006, this patent is the needle tube type nib, ball seat on its nib body, the nib body and outlet pipe are stainless steel and make, and adopt stainless steel, and material cost and processing cost are all than higher.
Summary of the invention
The invention solves the available technology adopting stainless steel and do nib, make material cost increase the shortcoming of processing difficulties, a kind of full pin type nib that adopts copper cylinder material to make various pens such as oil pen, gel ink pen and free ink pen is provided, lower material cost and cost of manufacture, simplified a kind of copper full needle-tube pen-point processing technology of processing.
The technical solution adopted for the present invention to solve the technical problems is: a kind of copper full needle-tube pen-point processing technology comprises the steps:
1.1 choose copper cylinder it is cut off, be cut into written length;
1.2 the copper cylinder that will cut off is clamped on the lathe, holes at copper cylinder with the perforating of the suitable band section of diameter;
1.3 the wherein end to copper cylinder carries out interior processing, makes the circular hole cavity of putting ball;
1.4 put into ball in the circular hole cavity that processes and do to close up and fix ball.
Adopt copper cylinder to do full pin type nib and can reduce material cost, can also simplify the process of nib, reduce written cost of processing; The perforating pin that adopts the band section can be realized the boring of the full pin type nib of reduced size as drill bit, and this copper full pin type can be used as the nib of kinds such as oil pen, gel ink pen and free ink pen.
Described perforating pin is a kind of special drill bit that uses at full needle-tube pen-point, and the processing of perforating pin comprises the steps:
2.1 choose high-intensity spring steel, diameter is controlled at 0.3mm-0.7mm;
2.3 spring steel is carried out integral quenching;
2.4 the spring steel after quenching is polished, the end of spring steel keeps 3/5 of original diameter, grinds off remainingly 2/5, makes the periphery of spring steel end form a section.Generally choose and the corresponding spring steel in the aperture of written internal ink water pipe, the strength ratio of spring steel is higher, again through spring is quenched, reach suitable hardness, satisfy the requirement of processing, the hardness of quenching will be chosen rationally, hardness is too low, boring is inconvenient, and too high, the increase of perforating pin fragility is easy to generate crackle; The face of cylinder of perforating needle end part is ground off 2/5, forms a section, and in rotary course, cutting material is discharged from the position of section, grinds a pointed cone at 3/5 place that keeps, and the tip is in the center of spring steel cylinder.
Its diameter of copper cylinder of choosing is 0.7mm-1.0mm, and length is controlled at 5mm-10mm, copper cylinder is fixed and is rotated in when boring, and the perforating pin maintains static.The size of perforating pin is less than the size of needle-tube pen-point, therefore the perforating pin maintains static when boring, copper cylinder rotation can improve whole stability, reason such as prevent to beat in the rotary course makes the fracture of perforating pin, the diameter of copper cylinder and length are generally set according to the needs of pen, comprise the diameter of nib ball.
The mode that can adopt an end directly to drill through during boring, as the two-way boring in preferred employing two ends and get through, then the lateral location of an end is stamped the uniform concave point of three indents therein.One end directly drills through needs high control precision, there is deviation to make the fracture of perforating pin easily slightly, adopt two-way boring to get through, as long as guarantee the axiality in the hole at two ends, thereby the degree of depth that just can reduce each boring is simplified process, make that the discharge cutting material is more smooth, also guaranteed the service life of perforating pin.
The position of concave point is 2/3 of a ball diameter from the distance of copper cylindrical end, and the bottom of circular hole cavity is the concave wall of three concave points, and the concave wall that adds three concave points in man-hour forms round bottom.The depth capacity of circular hole cavity is 2/3 of a ball diameter, after ball is put in the hole, inwall by concave point supports, in writing process, the wall of circular hole cavity plays the maintenance effect to ball, prevent from that for ball rolls smoothly, the sphere that matches with ball will be processed in circular hole cavity bottom.
Another kind of scheme: adopt an end boring during boring, an end is bored thoroughly, the other end does not bore and is enclosed construction.
During processing circular hole cavity, its round bottom is the closure in the middle of the copper cylinder, behind the processing circular hole cavity, processes the aperture that communicates with another side opening of closure at the round bottom place, and the base channel of circular hole cavity is gone out the groove that some roads are connected with aperture.The closure of not boring is as the bottom of circular hole cavity, be used for supporting ball, for ball is rolled smoothly, the sphere that matches with ball is processed in the bottom, process the groove that some with middle aperture communicates in the bottom of circular hole cavity, make the ink in the pen core can be seeped on the ball face, guarantee to write uninterruptedly that the quantity of groove will guarantee that flowing of ink is uninterrupted.
The invention has the beneficial effects as follows: adopt copper cylinder as nib, can reduce the cost of material, make nib with stainless steel and can reduce cost 30%; The stainless hardness of the hardness ratio of copper is low, but can satisfy the requirement of writing, worked copper is more prone to convenient than processing stainless steel, also reduce processing cost, can improve the efficient of processing, adopted the perforating pin of band section when nib is holed, keep perforating pin integral intensity, the convenient cutting material of discharging of section, perforating pin adopt spring steel also can improve the intensity of perforating pin through the polishing of quenching, and are not easy to rupture when boring; The mode that adopts two-way boring to get through when adopting concave point to support the structure of ball is processed, and can simplify process.
