Abstract
The utility model discloses a mould for producing long lathes, comprising two clamping plates, a side plate, an upper punch and a lower punch arranged between the two clamping plates and characterized in that the two ends of the clamping plates are both provided with a bar shaped channel section used for clamping the side plate; the two ends of the side plate are provided with trapezoid clamping ends for matching with the bar shaped channel sections; the bar shaped channel sections and the trapezoid clamping ends form clamping structures through which the clamping plates are in fixed connection with the side plate. According to the utility model, the clamping structures are arranged instead of pins for fixedly connecting the clamping plates with the side plate; the characteristics of the clamping plate and the side plate are utilized to fix the punches and to minimize stress concentration. When the sides are under side compression, according to a traditional mould, the side compression is concentrated on small side plates on two ends and the caused stress concentration leads to the fracture of the side plate; while according to the mould of the utility model, the side compression lies on punch surfaces to reduce fracture; the operation for producing the long lathes is simple, the mould is convenient for manufacture, the manufacture cost is low and the production efficiency is high.
Description
Technical field
The utility model relates to a kind of mould of producing the carbide alloy long lath, belongs to the machinery knives manufacture technology field.
Background technology
As shown in Figure 1, the production carbide alloy long lath mould that tradition is used, it comprises the clamping plate 1 of both sides, upper punch 3 and low punch that two clamping plate, 1 centre is set and the side plate 2 that is arranged on clamping plate 1 two ends, the mould of this structure, its two ends are fixing with side plate 2 and two clamping plate 1 by latch 4, this kind Mold Making complexity, and when the side is subjected to side pressure, the side plate 2 two-end part stress that latch 4 is installed are concentrated, cause the fracture of clamping plate 1 easily, and because every production a slice long lath will be adorned latch one time, produce complicated and trouble, production efficiency is low.
The utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of production efficiency height, and die life is long, production long lath mould simple to operate.
The utility model is achieved through the following technical solutions: a kind of production long lath mould, comprise clamping plate, side plate and be arranged on upper punch and low punch between the clamping plate, it is characterized in that, be equipped with the strip-shaped clamp groove that is used to engage side plate at described clamping plate two ends, described side plate two ends are provided with the trapezoidal card end suitable with strip-shaped clamp groove, this strip-shaped clamp groove and trapezoidal card end constitute snap-in structure, and described clamping plate connect firmly with side plate mutually by snap-in structure.
As preferred version, be trapezoidal mouthful in the groove of described strip-shaped clamp groove, it is suitable with trapezoidal card end. when being subjected to side pressure in the side, all lateral pressures have avoided stress concentrated on whole punch face, have reduced the fracture of clamping plate.
The utility model connects firmly clamping plate and side plate by snap-in structure is set, and has cancelled and has used the fixing of pin, uses the characteristics of clamping plate and side plate self, and fixedly drift reduces stress and concentrates; When the side is subjected to side pressure, avoided traditional lateral pressure to be concentrated on the little side plate at two ends, cause the concentrated side plate fracture that causes of stress, and all lateral pressure of this kind mould reduces fracture on whole punch face, and is simple to operate when producing long lath, Mold Making is convenient, long service life, cost of manufacture is low, the production efficiency height.

The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with the specific embodiment, further set forth the utility model.
Referring to Fig. 6, a kind of production long lath mould of the present utility model, it comprises clamping plate 11, be installed in the side plate 12 of clamping plate 11 ends and install between two clamping plate 11 upper punch 13 and low punch 14.
Referring to Fig. 2 to Fig. 5, all be processed with the strip-shaped clamp groove 110 that is used to engage side plate 12 at clamping plate 11 two ends, these side plate 12 two ends are processed with the trapezoidal card end 120 suitable with strip-shaped clamp groove 110, strip-shaped clamp groove 110 constitutes snap-in structure with trapezoidal card end 120, described clamping plate 11 connect firmly with side plate 12 mutually by snap-in structure, have avoided traditional lateral pressure to be concentrated on the little side plate 12 at two ends and side plate 12 fractures that cause.
In the present embodiment, be trapezoidal mouthful in the groove of strip-shaped clamp groove 110, it is 120 suitable that itself and trapezoidal card are held, and is convenient to fix.Two clamping plate 11 fasten with the trapezoidal card end 120 of the strip-shaped clamp groove 110 of holding with side plate 12 two ends, place low punch 14 and upper punch 13 at two clamping plate, 11 middle parts.Because clamping plate 11 and side plate 12 are connected by snap-in structure, when being subjected to side pressure in the side, all lateral pressures have avoided stress concentrated on whole punch face, have reduced the fracture of clamping plate 11.
Referring to Fig. 7, when clamping plate 11, side plate 12, upper punch 13, low punch 14 are assembled together the pressure long lath, can find out side institute stressed " F " by force analysis, by force resolution, F1=0, F=F2*COS α, power reduces greatly, thereby has guaranteed service life.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof
