Abstract

The present invention relates to a kind of manufacture method of drawer sliding rail, it is asymmetric that it mainly solves the left and right sides slide rail that in the past used in pairs, even the problem of generation torsional deformation, this method is to go out the plane template of symmetry in twos on a steel disc earlier, relend by the bending forming machine, its punching press is bent into symmetrical a pair of left and right sides slide rail disjunctor, again through central cutting, can obtain paired drawer sliding rail, the STRESS VARIATION that this method utilization is relative, prevented the torsional deformation of product effectively, simplified manufacturing and hypervisor, can improve the quality of products and production efficiency.

Description

The manufacture method of drawer sliding rail

The present invention relates to a kind of manufacture method of drawer sliding rail.

General drawer sliding rail is arranged on the bottom of drawer, cooperates another slide rail of drawer side, and the action of the roller on two slide rails, so that drawer slides smoothly when drawing back and closing.Because the manufacture method of present drawer sliding rail, all are manufacture methods with one chip, promptly earlier the material cutting is become single-chip template, compression moulding one by one again, but because slide rail is to use in pairs, must use two impact molding machines by manufacture method in the past, two groups of left and right sides slide rails are made respectively, process time that it need double and higher cost be the more important thing is, the slide rail of this independent compacting, because of under different condition, processing, it is subjected to the force direction difference, is easy to produce the torsional deformation phenomenon, causes defect ware, when using relatively in twos, normal produce the involutory tight or phenomenon that makes drawer draw the pass to have some setbacks because of asymmetric mutually, even shortened its service life greatly, this is the shortcoming place of drawer sliding rail manufacture method in the past just also.

At the problems referred to above, the object of the present invention is to provide a kind of improving production efficiency and product quality, eliminate the slide rail torsional deformation and be convenient to the slide rail manufacture method of job management.

Drawer sliding rail manufacture method of the present invention is mainly taked following step, chooses steel earlier, and punching again becomes plane template with its cutting then, and bending forming is the relative disjunctor of left and right sides slide rail again, is cut into two independently left and right sides slide rails at last.

Slide rail manufacture method of the present invention with relatively had following beneficial effect with class methods in the past:

1, simplify working process, it, just can be finished as long as one time punching molded for two kinds of symmetrical left and right sides slide rails.

2, improve the quality of products, owing to the stress symmetric on two slide rails about plane template is when punch forming is repealed by implication, so product can not produce distortion or distortion, when the counterpart application of the left and right sides, can be accurately involutory, overcoming in the past fully, processing method causes the asymmetric shortcoming in the left and right sides.

3, can improve working (machining) efficiency, it must not make left and right sides slide rail respectively, just can obtain a pair of product with the time processing program.

4, because of the present invention can make more products, and need only want an impact molding machine with less man-hour, can effectively reduce cost, improve product competitiveness.

5, be convenient to management,, be convenient to automated production, overcome and to produce a left side or the inconsistent shortcoming of right slide rail quantity in the past when making separately by paired manufacturing.

Existing conjunction with figs. is described as follows manufacture method of the present invention.

Description of drawings:

Fig. 1 is the manufacture method flow chart of drawer sliding rail of the present invention;

Fig. 2 is the plane template schematic diagram in the inventive method;

Fig. 3 is stamping forming paired sliding rail structure figure in the method for the present invention;

The left and right sides slide rail finished product stereogram of Fig. 4 for cutting into method of the present invention.

As shown in Figure 1, the flow chart of the manufacture method of drawer sliding rail of the present invention, its process step is: choose steel disc 1 → punching 2 → cut 3 → punching press bending forming 4 → central authorities' cutting 5; Promptly at first choose a plane steel disc 11 of appropriate size, with steel disc 11 deliver to perforating press in the precalculated position by the required hole 12 of designing requirement punching out, as shown in Figure 2, directly cutting is symmetrical in twos plane template 13 again, then plane template 13 is struck out the left and right sides slide rail disjunctor 14 of symmetry through the bending forming machine, as shown in Figure 3, the middle position from slide rail disjunctor 14 cuts into separate left slide rail 15 and right slide rail 16 at last, as shown in Figure 4.

Claims (1)

1, a kind of manufacture method of drawer sliding rail is characterized in that, its manufacturing step is:

A. choose steel disc: the steel disc of choosing appropriate size;

B. punching: press the designing requirement of slide rail, at the required hole of the precalculated position of steel disc punching out;

C. cutting: with the steel disc cutting after the punching is the plane template of symmetry in twos;

D. punching press bending forming: the plane template punching press is bent to form is the relative disjunctor of left and right sides slide rail;

E. central authorities' cutting: the slide rail disjunctor is cut into left slide rail and right slide rail from its middle position.
