Abstract
The utility model discloses a material-pulling pin mechanism which comprises a base. The material-pulling pin mechanism is characterized in that a pushing spring is arranged at one side portion of the base, a material-pulling pin fixing block is arranged at the upper portion of the base and a spindle is arranged in the middle portion of the base. The material-pulling pin mechanism is further characterized in that a material-pulling pin is arranged on the material-pulling pin fixing block which is provided with an inclined block, a mandrill is arranged in the material-pulling pin fixing block and two ends of the mandrill are installed on the base. A square block is arranged at one side of the inclined block and the other end of the square block is connected with the material-pulling pin. A jack-up spring is arranged at the lower end of the material-pulling pin and the other end of the jack-up spring is connected with the base. According to the material-pulling pin mechanism, the material-pulling pin is installed on the base in a floating installation mode, so that the material-pulling pin can be steadily inserted into a circler hole on the material strap, at the same time the whole base can be pushed to move along the pushing of the spring and material feeding movement is carried out. The material-pulling pin mechanism has the advantages of simple processing method of the material-pulling pin which is easy to broke, few manufacture procedures, low processing cost and convenient replacement.
Description
Technical field
The utility model belongs to punch process mould field, specifically, relates to a kind of material pin mechanism of drawing.
Background technology
In the existing technique, usually use diel stamping forming mode on sheet metal strip to make the hardware part.Existing diel comprises upper die and lower die, and patrix is provided with tiltedly to carve and rushes sub-﹐ counterdie and be provided with and draw material machine assembly. during work, counterdie maintains static, and patrix lifts first, falls again, utilizes the effect of tiltedly carving punching pin and drawing the material machine, finishes feeding action in the mould.Draw material pin mechanism in whole equipment, have very consequence, its guarantee of work entering smoothly of strip draw material machine assembly, guaranteed the smooth and easy of punch process.Present to draw material mechanism all be all-in-one-piece, and draw the most advanced and sophisticated position of material needle section to be easy to damage, and it is many, long in time limit newly to do the manufacturing procedure that part needs after drawing the most advanced and sophisticated bit loss of material needle section bad, and maintenance cost is high.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provide a kind of simple in structure, change convenient and maintenance cost is low draws material pin mechanism.
For addressing the above problem, the technical scheme that the utility model adopts is:
A kind of material pin mechanism of drawing comprises base, and it is characterized in that: a sidepiece of base is equipped with the promotion spring; The top of described base is equipped with draws the material pin; The middle part of described base is provided with mandrel.
Say further:
Describedly draw the material pin to be installed in to draw on the material pin fixed block, draw on the material pin fixed block and be provided with the symmetrical skewback of installing; Described drawing in the material pin fixed block is provided with mandrel, and the two ends of mandrel are installed on the base.
Further say:
One side of described skewback is provided with square, and the material pin is drawn in the other end connection of square.
The described lower end of material pin fixed block of drawing is provided with the jack-up spring, and the other end of jack-up spring connects base.
Owing to adopted technique scheme, compared with prior art, the utility model will draw the bottom of material pin fixed block to be connected by spring with base, skewback and draw material pin sidepiece to be fixed on by square and draw material pin fixed block Shang ﹐ to draw to expect that the pin fixed block is hinged on the base by mandrel.Such design, it is simple to hold the flimsy material pin processing method of drawing, and manufacturing procedure is few, and processing cost is low, and it is convenient to change.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments simultaneously.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is the side structure schematic diagram of Fig. 1.
Among the figure: the 1-base; 2-promotes spring; 3-jack-up spring; 4-draws material pin fixed block; The 5-mandrel; The 6-skewback; The 7-square; 8-draws the material pin; The 9-axle sleeve; The 10-mandrel.
The specific embodiment
Embodiment:
As shown in Figure 1 and Figure 2, a kind of material pin mechanism of drawing comprises base 1, and a sidepiece of base 1 is equipped with and promotes spring 2.The top of described base 1 is equipped with draws material pin 8, and the middle part of base 1 is provided with mandrel 10.Axle sleeve 9 is installed together by mandrel 10 and base 1.
In the present embodiment, describedly draw material pin 8 to be installed in to draw on the material pin fixed block 4, draw on the material pin fixed block 4 and be provided with the symmetrical skewback 6 of installing, described drawing in the material pin fixed block 4 is provided with mandrel 5, and the two ends of mandrel 5 are installed on the base 1.One side of described skewback 6 is provided with square 7, and the other end of square 7 connects to draw expects pin 8.
In the present embodiment, draw the lower end of material pin fixed block 4 to be provided with jack-up spring 3, the other end of jack-up spring 3 connects base 1.
In the present embodiment, draw the bottom of material pin fixed block to be connected by spring with base, skewback and draw material pin sidepiece to be fixed on by square and draw material pin fixed block Shang ﹐ to draw to expect that the pin fixed block is hinged on the base by mandrel.Such design. will draw the material pin to be installed on the base by floating type mounting means, the drop-down material pin of the effect of jack-up spring can be stable be inserted in the circular hole on the strip, promote simultaneously spring and can promote whole base motion, implement the feeding action.Such design, it is simple to hold the flimsy material pin processing method of drawing, and manufacturing procedure is few, and processing cost is low, and it is convenient to change.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or akin technical scheme, all belong to protection domain of the present utility model.
