Abstract
The invention discloses an antiskid nail core which is of a two-section structure. The antiskid nail core comprises an antiskid nail core body and an antiskid nail core cap and the antiskid nail core body is of a cone structure. The antiskid nail core is characterized in that the antiskid nail core body is of a two-section structure; one section of the antiskid nail core body is a cone and the other section of the antiskid nail core body is a polygon cone; and the cone and the polygon cone have different tapers. The polygon cone of the antiskid nail core body is connected to the upper surface of the cone and the taper of the polygon cone is greater than that of the cone. According to the invention, by changing the cone of the antiskid nail core into the polygon cone, an antiskid nail can be effectively prevented from slipping in an antiskid nail core seat and antiskid performance of the antiskid nail is improved; and the antiskid nail with the polygon cone is particularly beneficial for preventing skidding on a pavement covered with ice and snow and the pavement covered with ice and snow can be effectively grasped by corner angles of the polygon cone so as to prevent a wheel from slipping.
Description
technical field
The present invention relates to a kind of parts for automobile tyre antiskid and preparation method thereof, particularly a kind of anti-sliding nail core in motor tire surface and preparation method thereof that is embedded in, is mainly used in making automobile antiskid tire.
Background technology
On the road surface in the world of ice and snow, due to icy on road, often cause motor tire to occur skidding in the winter time; In order to prevent that motor tire from skidding on ice and snow road, present many tires have all adopted the form that is embedded in anti-skid stud at tire to stop tire to skid on ice and snow road.Anti-skid stud in this embedding motor tire is all generally that the anti-sliding nail core that adopts hard alloy to make packs in anti-skidding nail seat, more anti-skidding nail seat is arranged in motor tire surface; Hard alloy anti-skid stud is mainly used in the motor tire, climbing boot boots, ski pole in cold wet area etc. and locates, and according to different use, with to inlay grooved different, its specification has different requirements, but material is mainly with features such as wear-resisting, low temperature resistant, high hardnesss.Anti-skid stud product has been widely used in the ground such as East Asia, North America, Eastern Europe, Northern Europe.In order to improve antiskid capability, also there are many people to think hard in the improvement of anti-skid stud, by patent retrieval, find that there is following patents related to the present invention:
1, application number is CN92237186.5, the Chinese invention patent that patent name is " tire stud " discloses a kind of tire stud, there is a recess at the middle part that it is characterized in that the circular head of a nail, one end of nail bar is integrated at head of a nail recess place and head of a nail vertical welding, anti-skid stud in tire to the saturating tire of thorn, nail tip appears from the decorative pattern boss of tire, and the head of a nail is placed in tire inboard.The feature that the present invention has is simple in structure, cost is low, easy for installation, travel in the smooth road of snow and ice cover owing to having adopted such scheme can make bicycle safe, guaranteed safety by bike in people winter.
2, application number is CN00120326.6, the Chinese invention patent application that patent name is " studded tire, its manufacture method and tire stud and its mfg. moulding die " discloses a kind of method of manufacturing the tire of automotive wheel, comprise a tread surface with outside face, mass part is housed from the outstanding metal tire stud of described outside face on it, the method step is: manufacture a green tire; Described tire stud is inserted and remained on the predetermined base in a sulfurizing mould; Described green tire is filled in mould; Matched moulds; Described green tire is added to sulphur, open described mould and take out curing tire; Described base has clearence degree at the latter's opening part, can not interfere with described sector and described tire stud like this, and keep the outside face of their relative tread surfaces substantially vertically arranged.
3, application number is CN200410007143.1, the Chinese invention patent application that patent name is " automobile tyre antiskid nail and manufacture method " discloses a kind of automobile tyre antiskid nail, its entire body is made by hard alloy, hard alloy formula following (percentage by weight): cobalt powder 7.6-9.4%, carbonized tungsten 75.0-92.0%, tungsten titanium solid solution 0-15.6%.Its manufacture method is: the cobalt powder, carbonized tungsten, the tungsten titanium solid solution that take specified amount, carry out mixed grinding take in the wet milk that alcohol is medium, drying, mix glue, granulation, obtain uniform powder mixing pellet, it is compressing that powder mixing pellet packs mould into, pressed compact, through vacuum-sintering, passivation, cleaning, dehydration, oven dry, obtains the shinny automobile tyre antiskid nail of any surface finish.Anti-skid stud physical and mechanical properties index is as follows: density (g/cm3) 12.5-14.9, hardness (HRA) >=89.5, bending strength (N/mm2) >=1470, adapts with the physical and mechanical properties of anti-slip automobile tire, effectively improves tire anti-slip performance and used life.
