Abstract

The present invention provides a method for producing rectangular fibre pen core, and its key lies in that when the rectangular pen core core-bar is primarily formed, its appearance size is slightly larger than generally-defined size, then before said core bar is cut into single pen core a procedure is added, i.e. four sides of core bar of rectangular pen core are ground by using abrasive wheels of four working positions respectively so as to obtain higher appearance accuracy and surface finishment, and can greatly reduce assembling error of rectangular pen core, and can improve its use performance.

Description

A kind of processing method of rectangular fiber lead

The present invention relates to the processing method of particularly a kind of rectangular fiber lead core bar of a kind of fiber pen core.

Now the preparation method of viscose fibre type pen core generally is with multiply (by specification, vary in size) chemical fibre silk adhesive on behind the high-temperature shaping, is cut into the stock of 0.6--1m again after the drying tunnel oven dry.Can divide circular and rectangle two big classes according to the difference of core bar cross section.After typing, generally all grinding is carried out on its surface for circular pen core, to reach the assembly precision requirement with centerless grinder.And the rectangle pen core be because the restriction of profile can not adopt general-purpose grinder to process, thereby current technology generally no longer carries out grinding to it, directly cuts off by the length of single pen core and enters down road bistrique operation.The required precision when assembling penholder after yet the once setting that only depends on fiber is difficult to satisfy.Because of its profile error is bigger, pine phenomenon when tight when assembling occurs during penholder easily, slightly one firmly, nib is just gone in the retraction penholder, causes the phenomenon that can't continue to use when writing.

The objective of the invention is to improve the form accuracy and the surfacing fineness of rectangular fiber lead, improve the credit rating and the serviceability of pen core.

The present invention is achieved in that when rectangle pen core core bar is tentatively finalized the design, it is slightly bigger than what stipulate usually to make its appearance and size, then before core bar is cut into single pen core, increase by a procedure again, grinding is carried out with the emery wheel of four stations respectively in four sides to rectangle pen core core bar, to reach corresponding form accuracy and surface smoothness.The rigging error of rectangle pen core is reduced greatly, thereby improve the serviceability of fibre-tip pen.

The present invention is described in further detail below in conjunction with accompanying drawing.

Fig. 1. be the manufacture craft flow chart of rectangular fiber lead.

Fig. 2. carry out the schematic diagram of four sides grinding for the rectangle pen core.

Fig. 3. be the vertical view of Fig. 2.

Fig. 4. be the left view of Fig. 2.

In conjunction with Fig. 1, Fig. 2, Fig. 3, the chemical fibre silk is through doubling, typing (its appearance and size is bigger slightly than usually), gluing, oven dry, cut into the rectangle stock (6) about 0.6-1m, then this stock is sent into about having, about four station emery wheels (1), (2), (3), (4) and send bar pinch roller (5) and grinding when carrying out four planes of grinding machine that positioning baffle (7) constitutes.Certain this process also can be divided into two or more steps carries out, as coming four flat surface grindings of rectangle pen core with two double face abrading machines or many single face grinding machines.Surface smoothness through the rectangle core bar after the grinding of four sides is higher, and its appearance and size precision has reached the requirement of regulation.Again this stock is cut into single pen core as required, after bistrique, cleaning, oven dry, be the finished product pen core.The rectangular fiber lead that adopts described processing method of the present invention to produce has the advantages that outer form error is little, surface smoothness is high, has improved the credit rating of product greatly.

Claims

1, a kind of processing method of rectangular fiber lead, be the multiply chemical fibre to be carried out steps such as doubling, typing, gluing, oven dry, cut-out, bistrique, cleaning, oven dry to constitute, it is characterized in that: it is slightly bigger than what stipulate usually to make its appearance and size when rectangle pen core core bar is tentatively finalized the design, then before core bar is cut off into single pen core, increase by a procedure again, use emery wheel (1), (2), (3), (4) of four stations to carry out grinding respectively four sides of rectangle pen core core bar (6).

2, the processing method of a kind of rectangular fiber lead according to claim 1 is characterized in that said increase is that the step that is divided into more than 2 times or 2 times is finished to the operation that pen core core bar (6) carries out the four sides grinding.
