Abstract

The utility model is a kind of composite material bat, be have with give birth to the silica gel bat as in the composite hollow barred body that is molded as, the hollow barred body comprises a lever, in lever wherein an end be made as round end, the other end then is provided with the driving part of one section external diameter greater than lever, seal with a plastic sheath in the driving part end, because the utility model is giving birth to the silica gel bat as the internal mold in the middle of being placed through, thus after the moulding hollow barred body peripheral wall structure of gained in a down-to-earth manner, even and can improve shock-resistant, knock intensity.

Description

Composite material bat

Technical field

The utility model is the technical field that belongs to bat, refers to a kind of composite material bat with homogeneous material especially.

Background technology

General baseball, the employed bat of softball has wood, perhaps aluminium is made, and along with the progress of material industry, also have with carbon fiber, the bat that composites such as glass fibre are made, make with composite, be earlier fiber to be dipped in advance in the resin solution and to form a preimpregnation lamination material, preimpregnation lamination material is reduced and is wound in outside the hollow nylon pipe according to reservation shape, nylon tube and preimpregnation lamination material are placed in the middle of the die cavity of a metal die again, during moulding blown in nylon tube inside, being exerted pressure in preimpregnation lamination material inside, cooperate the pressurization of mould simultaneously, heating and be solidified into bat.Yet the thickness at each position of nylon tube might not be identical, so ductility is also different, to such an extent as to inflation speed differs, causes the perisporium became uneven of the composite material bat made, and square stance is very easily because intensity inequality and flexural deformation.

The utility model content

In order to improve above-mentioned disappearance, main purpose of the present utility model is to provide a kind of anti-composite material bat that knocks intensity, improves speed of production that can improve bat that has.

Based on above-mentioned purpose, major technique means of the present utility model are to have the hollow barred body made from composite, the hollow barred body is to comprise a lever, in lever wherein an end be made as round end, the lever other end then is provided with the driving part of one section external diameter greater than lever, seal with a plastic sheath in the driving part end, this hollow barred body perisporium is the resin bed that comprises a composite fiber layer, is positioned at composite fiber layer both sides.

Implement after the above-mentioned technological means, the obtainable concrete benefit of the utility model is: because the utility model is giving birth to the silica gel bat as the internal mold in the middle of being placed through, so after the moulding hollow barred body peripheral wall structure of gained in a down-to-earth manner, even and can improve shock-resistant, knock intensity.

The specific embodiment

See also shown in Figure 1, composite material bat provided by the utility model is to have the hollow barred body made from composite 10, hollow barred body 10 is to comprise a lever 11, in lever 11 wherein an end be made as round end 12, lever 11 other ends then are provided with the driving part 13 of one section external diameter greater than lever 11, seal with a plastic sheath 20 in driving part 13 ends.Described hollow barred body 10 perisporiums are the resin beds 101 that comprise a composite fiber layer 100, are positioned at composite fiber layer 100 both sides.

See also the utility model shown in Fig. 2,3 and make the step of aforementioned hollow barred body 10:

Make silica gel bat 50 in all one's life: the profile of giving birth to silica gel bat 50 is identical with the hollow inside of the hollow barred body 10 desiring to make, its two ends and be longer than hollow barred body 10 two ends;

Coat the composite layer 51 that has flooded in giving birth to silica gel bat 50 surfaces, promptly give birth to the internal mold that silica gel bat 50 forms in the middle of being placed through;

Put into mould: the living silica gel bat 50 that the surface is coated with composite layer 51 is inserted in the middle of the die cavity 61 of a mould 60 wherein, and is involutory with the another mould again;

Heating, pressurization:, give birth to be heated Shi Yihui expansion and composite layer 51 internal perisporiums are exerted pressure of silica gel to the mould operation of heating, pressurize;

Moulding: after heating, pressurization, can be so that composite layer 51 hardened formings;

Extract living silica gel bat: will give birth to silica gel bat 50 and extract out, and promptly form hollow barred body 10 shown in Figure 1, and can reduce after giving birth to the silica gel cooling, to reuse;

Finished product.

Because the perisporium of employed living silica gel is the hollow barred body 10 inner life size desiring to make in the utility model manufacture process, can stablize fifty-fifty after it is heated and expand, and can on average apply pressure to composite layer 51 internal perisporiums, so hollow barred body 10 structures after the moulding are comparatively sturdy, can improve shock-resistant, knock intensity, and, can improve speed of production because it does not need to pass through aeration step again.

For another shown in Figure 4, the utility model can further be established one section groove 131 in driving part 13A surface, on this groove 131, be wound in a composite fiber bundle layer 135 with the composite fiber synnema, a resin bed 136 is established on these composite fiber bundle layer 135 surfaces again, has the characteristic of no breakpoint by twining with the composite fiber synnema, when its winding is coated in the driving part 13A surface of bat, can be because of contactless characteristic, and the intensity of raising driving part 13A, break through tradition and produce the abutment, and cause bonding station to be impacted or the problem of splintery absciss layer when hitting with laminating type.
