A kind of drawer sliding rail and manufacture method thereof
Technical field
The present invention relates to a kind of drawer sliding rail and manufacture method thereof.
Background technology
Traditional drawer sliding rail generally includes a pair of slide rail that is arranged at the drawer bottom both sides respectively.As shown in Figure 1, slide rail is made up of riser and arm-tie 1, and wherein riser is installed in the table inboard; Have installing hole 2 on the installed surface of arm-tie 1, and be socketed in the riser, can slide along riser.The installed surface of arm-tie 1 then is fastenedly connected with the outer surface of drawer, comes and goes along the riser inwall by arm-tie 1 and slides, and reaches the purpose that drawer opens and closes.
In traditional drawer sliding rail processing method, arm-tie 1 all is to process in pairs usually.On raw material, cut out shape, the corresponding blank of size, then blank is put on the perforating press, on the installed surface of blank, go out installing hole 2 by the precalculated position, again blank is processed as E type flap through operations such as the compacting of bender, bendings, at last E type flap is cut into two L type arm-ties 1 of symmetry.The general arm-tie of making according to this method 1, the outer of its installed surface is straight flange.On the structure of arm-tie 1, installing hole 2 has certain distance to the outer of arm-tie 1 installed surface, and the position of installing hole 2 and the big or small width that also has influence on arm-tie 1.Though this structure has guaranteed the requirement of slide rail working strength, the width of arm-tie 1 is as the criterion to arm-tie 1 installed surface outer with installing hole 2.Because when slide rail is installed, installed surface and drawer surface be for being fastenedly connected, slide rail in round sliding process installed surface stressed not quite, the processing method of traditional slide rail has obviously been wasted the material of non-fixed portions on installed surface.So in the drawer sliding rail that prior art is produced, arm-tie 1 exists the bigger defective of on-fixed position width, particularly in large batch of punch process, the arm-tie 1 of existing method manufacturing can cause material requested more in process, and production cost is higher.Therefore, traditional drawer sliding rail has not been suitable for the requirement of existing manufacturing cost.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, provide a kind of simple in structure, easy to manufacture, can save material, the drawer sliding rail that reduces production costs and manufacture method thereof.
The object of the present invention is achieved like this: a kind of drawer sliding rail, this drawer sliding rail comprises riser and two arm-ties, arm-tie is socketed in the riser, and can slide along riser, it is characterized in that: wherein an arm-tie is provided with the lug that is used for fixing, have installing hole on the lug, have the recess that coincide mutually with lug on another root arm-tie.
At least be provided with two groups of lugs and recess on any one in two arm-ties.
Described lug and recess are located at the two ends of arm-tie.
The middle part of two arm-ties is equipped with one group of lug and recess of coincideing mutually.
Two arm-ties are with the method punch forming of " cutting out a piece of cloth in a way with the minimum material to make two or more articles of clothing ".
The step of the method for described " cutting out a piece of cloth in a way with the minimum material to make two or more articles of clothing " is:
A. cut blank: as requested shape, size cuts out corresponding blank on raw material;
B. punching press bending forming: the siamese part that the blank punching press is bent into left and right sides arm-tie;
C. punching: on the installed surface of blank, go out installing hole as requested;
D. separate: left and right sides arm-tie is cut according to the shape of lug and recess.
The present invention compares with existing drawer sliding rail device and manufacture method thereof, has the following advantages:
1: the present invention goes out to have the identical mutually lug and the paired arm-tie of groove by the method stamping-out with " cutting out a piece of cloth in a way with the minimum material to make two or more articles of clothing " on blank, and installing hole all is arranged on the lug of arm-tie.Because the arm-tie upper lug packs in the recess on another arm-tie, therefore reduced installing hole and be subjected to position of mounting hole, big or small influence to the distance of arm-tie installed surface outer, promptly can realize fixed installation with less arm-tie width, therefore the width of arm-tie reduces, reduced the loss of material in the processing, improve the sheet material comprehensive utilization ratio, saved production cost.
2: the present invention by on blank with method moulding installing hole, lug and recess with " cutting out a piece of cloth in a way with the minimum material to make two or more articles of clothing ", this method has reduced the operation quantity of process, has reduced the mismachining tolerance of arm-tie simultaneously.Lug is not yielding in process, and the glacing flatness of effective installation accuracy that has guaranteed lug and recess and arm-tie, lug has improved crudy.

Fig. 1 is the structural representation of drawer sliding rail in the prior art.
Fig. 2 is the structural representation of most preferred embodiment of the present invention.
Fig. 3 is the principle schematic that the present invention can save material.
The specific embodiment
Below in conjunction with accompanying drawing embodiments of the invention are described.
According to Fig. 2 and shown in Figure 3, drawer sliding rail of the present invention comprises riser and two arm-ties 1, and it is inboard that riser is installed in table, and arm-tie 1 is socketed in the riser, and can slide along riser, and the other end then is fixed on the drawer by screw, nail or rivet.Wherein an arm-tie 1 is provided with the lug 3 that is used for fixing, the installation of lug 3 for convenience, and fillet all is with at the edge of lug 3.Have installing hole 2 on the lug 3, then have the recess 4 that coincide mutually with lug 3 on another root arm-tie 1.Steadiness in order to ensure arm-tie 1 is installed all has two groups of lugs 3 and recess 4 at least on any arm-tie 1, and lug 3 and recess 4 are located at the two ends of arm-tie 1.In addition, one group of lug 3 and recess 4 that coincide mutually can also be set at the middle part of two arm-ties 1.
Two arm-ties 1 are with method punch forming on blank of " cutting out a piece of cloth in a way with the minimum material to make two or more articles of clothing ", and its procedure of processing is:
A. cut blank: as requested shape, size cuts out corresponding blank on raw material;
B. punching press bending forming: the siamese part that the blank punching press is bent into left and right sides arm-tie 1;
C. punching: on the installed surface of blank, go out installing hole 2 as requested;
D. separate: left and right sides arm-tie 1 is cut according to the shape of lug 3 and recess 4.
For the glacing flatness of the installation accuracy that guarantees lug 3 and recess 4 and arm-tie 1, lug 3, installing hole 2, lug 3 and recess 4 all on arm-tie 1 stamping-out form.According to shown in Figure 3, utilize the forming method of " cutting out a piece of cloth in a way with the minimum material to make two or more articles of clothing ", determine the paired arm-tie 1 of coincide mutually lug 3 and groove 5 in the blank upper punch, installing hole 2 all is arranged on the lug 3 of arm-tie 1 simultaneously, compares with prior art, has saved the material between two lugs 3.Under the prerequisite that guarantees installing hole 2 positions and drawer sliding rail bulk strength, the width requirement of two arm-ties 1 is reduced, therefore in the processing of arm-tie 1, particularly in the occasion of producing in enormous quantities, the effect that drawer sliding rail of the present invention and manufacture method thereof save material, cut down finished cost is fairly obvious.
