Abstract

A manufacturing method and structure of hidden slide's slide unit, which the slide unit sets between upper and lower rail bars. The slide unit is made by long-plate-shaped substrate, which has the following steps: preliminary forming, pressure bending and rolling forming. First, preliminary forming and pressure bending can make substrate a prototype, then rolling forming can make substrate become a slide unit and the slide unit can be squeezed and concentrated. Therefore, the density of the slide unit structure is increased to enhance the strength of structure, which can avoid the slide be deformed, insure the operation quality of hidden slide can slide out smoothly, increase service life, decrease manufacturing cost, and have better economic benefit.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the invention will be further described, so that those skilled in the art can be better understood from the present invention and can be practiced, but illustrated embodiment is not as a limitation of the invention。

First, first refer to Fig. 1, shown in Fig. 2, the present invention provides sliding unit manufacture method and the structure thereof of a kind of hidden type slide, this sliding unit 20 utilizes the base material 201 of a long plate shape by first one-step forming, made by the steps such as pressurization bending and rolling and forming, wherein, first one-step forming by base material 201 in upper, bottom forms kink 202, central sections then forms support bar portion 203, again through processing machine pressurization bending, by upper, the kink 202 of bottom is bent to form the shape of falling S in the opposite direction, and winding is posted by support bar portion 203 side with end and forms closing circular arc, finally by rolling and forming, base material 201 is extruded the compactness increasing kink 202 and support bar portion 203, strengthen sliding unit 20 bulk strength, separately make between kink 202 and support bar portion 203, to form smooth shape, so as to two kinks 202 being extruded formation two sliding parts 21, and support bar portion 203 is compressed formation support portion 22, two sliding part 21 outer ends are also formed disymmetrical outside chute 211 by another, another in two sliding parts 21 inner formation inner slide 212, by above-mentioned manufacture method, this sliding unit is formed in one, and in correspondence, lower rail bar 11, 12 two sliding parts 21 in both ends with big head, separately between two sliding parts 21, form a support portion 22, and this two sliding part 21 is all arranged with chute 211 outside two in outer end symmetry, extend limit again from the inner side of two sliding parts 21 toward support portion 22 and have inner side chute 212, housing for ball 23, and between inner side chute 212 and support portion 22, form a smooth shape。

The composition of its structure and actually used state, then refer to Fig. 3, Fig. 4, shown in Fig. 5, this sliding unit 20 coordinates the upper rail bar 11 being mounted on hidden type slide 10, between lower rail bar 12, wherein this sliding unit 20 provides some balls 23 to be located in outside chute 211 and inner side chute 212 respectively at two sliding parts 21, then is entered the upper rail bar 11 of hidden type slide 10 by two sliding part 21 groups respectively, in lower rail bar 12, wherein rail bar 11 on this, lower rail bar 12 is respectively provided with a conduit 111, 121, and in conduit 111, 121 sides are bent to form limiting section 112 inside, 122, whereby sliding unit 20 groups is entered upper rail bar 11, the chute 111 of lower rail bar 12, when 121, in order to the ball 23 of outside chute 211 being limited to conduit 111 simultaneously, forming rolling slip state in 121, the ball on inner side chute 212 is then subject to conduit 111, the limiting section 112 of 121, 122 cladding restrictions, and have rolling slip effect equally, utilize sliding unit 20 and ball 23 in upper rail bar 11, in lower rail bar 12, sliding rolls, and reaches slide rail pull comparatively smoothly and uses state, in sum, so that completing a kind of hiding is rail structure。

Structure by means of above-mentioned specific embodiment, following advantage can be obtained: sliding unit 20 of the present invention with a base material 201 through first one-step forming, the steps such as pressurization bending and rolling and forming are constituted, first passing through just one-step forming and pressurization bending allows base material 201 form a blank, again through rolling and forming, base material 201 is shaped as a sliding unit 20, and make sliding unit 20 have an extruding by rolling and forming, the effect concentrated, increase the density of texture of sliding unit 20 entirety whereby, and then reach the reinforcement of structural strength, sliding unit 20 doubt of deformation in time using can not only be avoided, guarantee smooth degree and operation quality that hidden type slide 10 pull uses, there is preferably service life simultaneously, can also effectively reduce manufacturing cost on the other hand, tool economic benefit。
