Abstract

A structure of dust boot of rolling element is mainly characterized in a spring as a main design; elastic plastic material is covered on the surface of an outer layer of the spring and then pressed into a suitable size to form a set body which is provided for a rolling element to sleeve in, thereby preventing scraps interfering and keeping a normal movement of the rolling element. The utility model can prevent fallen steel beads into a diehead holder if the steel beads in the rolling element fall down because of abrasion wear, thereby preventing the steel beads from damaging the diehead holder and maintaining integrality of the diehead holder. The utility model has compact structure, convenient assembly, low manufacturing cost, strong market competition and industrial productive value.

Description

The structure of rolling element dirt-proof boot

＜one〉technical field:

The utility model system is relevant with the structure of dirt-proof boot device; person's use drawback will generally commonly not used by main system; do an improvement and make it more perfect, more detailed it, refer to a kind of die holder normal operation of whole group and start structure of rolling element dirt-proof boot smoothly of protecting especially.

＜two〉background technique:

The structure that occurs on the market in the past, there is not dirt-proof boot on the rolling element, cause rolling element to expose in the die holder, make some waste material bits enter the steel ball that comes off in rolling element and the rolling element and enter in the die holder, influence the normal operation of rolling element, cause start to have some setbacks, cause manufacturing efficiency not high, the market competitiveness reduces, and is not inconsistent industrial production and is worth, and economic profit reduces relatively.

＜three〉summary of the invention:

Main purpose of the present utility model is to utilize the design of dirt-proof boot apparatus structure of the present utility model, reaches protection die holder and start purpose smoothly, and the person's of commonly using drawback is improved, and the value that provides industrial circle to utilize makes it to have economic benefit.

The structure of a kind of rolling element dirt-proof boot of the utility model, be primarily characterized in that: it is to be body design with the spring, at the spring superficies flexible plastic material of coating tool then, and it is compressed into a suitable size, form a body, for being nested with rolling element.Can prevent behind this dirt-proof boot of rolling element overcoat that material from disturbing, the proper motion that keeps rolling element, and the steel ball in this rolling element is as coming off because of abrasion cause, and then this dirt-proof boot can prevent that the steel ball that comes off from entering die holder, thereby stop steel ball that mould is damaged, to safeguard the integrity of mould.

The structure of a kind of rolling element dirt-proof boot of the utility model, its advantage is:

1, can protect rolling element, make the die holder start smooth and easy, and can increase the attractive in appearance of whole group die holder.

2, one-body molded, it is convenient to make, and can produce in a large number, and economic profit is improved relatively.

3, simple for structure, assembling processing is all convenient.

4, meet economic benefit, have industrial production and be worth.

5, low cost of manufacture improves productive profit, market competitiveness height.

＜four〉description of drawings:

Fig. 1 is the perspective exploded view of the utility model.

Fig. 2 is the combination cross-sectional schematic of the utility model.

Fig. 3 is the combination cross-sectional schematic of the utility model.

Fig. 4 is the enforcement view of the utility model.

Number in the figure is as follows:

10 springs, 20 plastic materials, 30 guide pillars

40 guide pin bushings, 50 steel ball sleeves

＜five〉embodiment:

At first, see also Fig. 1 to shown in Figure 4, the structure of a kind of rolling element dirt-proof boot of the utility model, be primarily characterized in that: it is to be body design with spring 10, at the flexible plastic material 20 of its superficies coating tool, by this, it is compressed into a suitable size, form a body, for being nested with rolling element: this rolling element contains a guide pillar 30 and a guide pin bushing 40, and has steel ball sleeve 50 in guide pin bushing 40, in view of the above, can prevent that waste material from disturbing, and keeps the proper motion of rolling element.

When assembling is implemented, please continue to consult Fig. 1 to shown in Figure 4, be to make up by said elements, its group is upright very convenient and rapid, makes because of the dirt-proof boot of the utility model is formed in one, and is not only very quick on processing procedure, and cooperate this rolling element combination, be able to the very convenient entire combination of finishing.

During enforcement, the dirt-proof boot of the utility model can be nested with this rolling element, and the dirt-proof boot of the utility model can be compressed to suitable size, reaches the effect of expection; And the waste material that the rolling element of the utility model in preventing to operate produced in the die stamping process disturbs, thereby the normal start that can keep rolling element, and the steel ball in this rolling element is as coming off because of abrasion cause, then the utility model can prevent that the steel ball that comes off from entering die holder and stoping steel ball that mould is damaged, to safeguard the integrity of mould; The person after this rolling element installs the utility model additional, not only can increase the aesthetic property of whole group die holder in addition, more can increase the surcharge of product, promotes the market competitiveness, has the industry productive value.

Claims

1, a kind of structure of rolling element dirt-proof boot is characterized in that: it is to be body design with the spring, at this flexible plastic material of spring superficies coating tool and be compressed into pre-sizing and form one for being nested with the body of rolling element.
