Abstract

The utility model provides a material guiding structure of an extension mould, and the structure comprises an upper mould seat, an extension punch, material unloading plates, an extension female mould, a lower mould seat, a mandril and two upper material guiding and lifting blocks; the extension punch is arranged below the upper mould seat and passes through the material unloading plates; the upper material guiding and lifting plates are arranged below the material unloading plates which are in equal distance with the extension punch; the extension female mould is arranged above the lower mould seat and at the position corresponding to that of the extension punch; the mandril is arranged between the material unloading plates and the lower mould seat, and passes through the material unloading plates; a spring is sleeved on the mandril; and two openings with the sizes and the positions corresponding to those of the mandril are arranged on the upper mould seat. According to the material guiding structure of the extension mould, the problems in the prior art that a material lifting height is restricted by the height of the mould and the structure is quite complicated are solved, the impact of the height of the mould and the amount of compression of the spring on material guiding and lifting is eliminated, a material guiding and lifting height can be improved to the largest extent, simultaneously the processing to a lower mould is totally cancelled, so that the on-line quick installation and detachment of a tension groove are convenient.

Description

Drawing die guide structure
Technical field
The utility model has related to a kind of mould structure, and especially a kind of drawing die guide structure belongs to the material extending technical field.
Background technology
Drawing die is that modern product is made a kind of mould that extensively adopt in the field, is made up of the concavo-convex mould that matees up and down usually.Traditional drawing die is as shown in Figure 2; Drawing die in process of production; Guide material lift pin 7 ' be fixedly mounted on stripper 5 ' on, guide by guide material lift pin 7 ' on groove realize that material lift provides active force upwards to realize by guide material lift pin 7 ' following spring 15; But because spring is compressed with certain limit, raising material lift height that can not be unlimited under the certain situation of mould height.And guide material lift pin 7 ' need pass die block 9 ' with backing plate 10 '; Spring 15 need pass backing plate 10 ' with die shoe 11 '; Make near the die shoe 11 of stretching die 8 ' on about stand in great numbers, the structure more complicated has been occupied many die spaces; The 8 online quick mounting or dismounting of stretching die have been had a strong impact on, inefficiency in the process of material extending.
The utility model content
The utility model technical problem to be solved provides a kind of drawing die guide structure; Eliminated the influence that the guide material lift receives mold height and amount of spring compression; Realize improving to greatest extent guide material lift height; Cancel counterdie processing, saved many processing charges, made things convenient for the online quick mounting or dismounting of stretching die.
To achieve these goals; The technical scheme that the utility model adopted is: a kind of drawing die guide structure; Comprise upper bolster, stretching drift, stripper, stretching die, die shoe and push rod, it is characterized in that: also comprise two overhead guide material lift pieces, said stretching drift is installed in the upper bolster below; And passing stripper, overhead guide material lift piece is installed in from the equidistant stripper of stretching drift below; Said stretching die is installed in and corresponding die shoe top, the drift position that stretches; Said push rod is installed between stripper and the die shoe, and passes stripper, is arranged with a spring on the push rod, and said upper bolster is provided with two corresponding openings of the size positions with push rod.
Aforesaid a kind of drawing die guide structure is characterized in that: said overhead guide material lift piece is the L type.
Aforesaid a kind of drawing die guide structure; It is characterized in that: between said upper bolster and the stretching drift fixed head backing plate and fixed head are installed also; The stretching drift is fixed on the below of fixed head backing plate through fixed head, said fixed head backing plate and fixed head be provided with two with the corresponding opening of push rod size positions.
Aforesaid a kind of drawing die guide structure, it is characterized in that: between said stretching die and the die shoe die block and backing plate are installed also, the stretching die is fixed in the die block; Push rod passes die block and backing plate, and said spring passes die block, between stripper and backing plate.
Aforesaid a kind of drawing die guide structure is characterized in that: said die shoe below is equipped with a plurality of mould pin.
The beneficial effect of the utility model is: through overhead guide material lift piece being directly installed on the movable stripper; Realize guide and material lift by its profile " L "; Cancelled counterdie processing; Eliminate the influence that the guide material lift receives mold height and amount of spring compression, realized improving to greatest extent guide material lift height, made things convenient for the online quick mounting or dismounting of stretching die.
Description of drawings
Fig. 1 is the sectional view of drawing die guide structure;
Fig. 2 is the sectional view of existing drawing die guide structure.
The specific embodiment
To combine Figure of description below, the utility model will be further described.
As shown in Figure 1; The utility model provides a kind of drawing die guide structure, comprises upper bolster 1, fixed head backing plate 2, fixed head 3, stretching drift 4, stripper 5, overhead guide material lift piece 7, stretching die 8, die block 9, backing plate 10, lower bolster 11, mould pin 12, push rod 13 and spring 14.
Stretching drift 4 is installed in upper bolster 1 below; And pass stripper 5; Fixed head backing plate 2 and fixed head 3 also are installed between upper bolster 1 and the stretching drift 4; Stretching drift 4 is fixed on the below of fixed head backing plate 2 through fixed head 3, and overhead guide material lift piece 7 is installed in from stretching drift 4 equidistant strippers 5 belows, and said overhead guide material lift piece 7 is the L type; Stretching die 8 corresponding die shoe 11 tops, drift 4 positions that are installed in and stretch also are equipped with die block 9 and backing plate 10 between stretching die 8 and the die shoe 11, stretching die 8 is fixed in the die block 9; Push rod 13 is installed between stripper 5 and the die shoe 11, passes stripper 5 above, passes die block 9 and backing plate 10 below, is arranged with a spring 14 on the push rod 13, and said spring 14 passes die block 9, between stripper 5 and backing plate 10; Be respectively equipped with two corresponding openings of the size positions with push rod 13 on said upper bolster 1, fixed head backing plate 2 and the fixed head 3.
When utilizing this mould to stretch; Material to be stretched 6 is fixedly mounted on the L type overhead guide material lift piece 7; Make 4 pairs of materials of stretching drift 6 carry out punching press after upper bolster 1 applied downward active force, utilize stretching groove 8 to make material 6 be drawn as the shape identical with the groove 8 of stretching.In the process of punching press,, be that stripper 5 downward wedging rings are located at the spring 14 on the push rod 13 because 3 pairs of strippers 5 of fixed head provide a downward power.Punching press is mentioned upper bolster 1 after accomplishing, and utilizes the elastic force of spring 14 that stripper 5 is upwards lifted, and is convenient to take off the material 6 that compression is accomplished, and the quick mounting or dismounting of the die 8 that can stretch simultaneously are convenient to next material is carried out punching press.
