Abstract
The utility model discloses a side limit structure of long rod stamping mould, comprising an upper mould and a lower mould. The upper mould is provided with a punch head. The both sides of the punch head are vertically fixed with a pair of sidewise spacer pins at least, and each sidewise spacer pin is provided with a straight flange. The two-two sidewise spacer pins are relatively arranged on the both sides of the punch head. The distance between the relative straight flanges is the width of the long rod. The front of the straight flange is also provided with a conical shape point. The lower mould is opened with a plurality of offset holes corresponding to the location of the sidewise spacer pin. The utility model guarantees the width and the size of the long bar to be not changed through the lateral force provided by the sidewise spacer pin. The side guiding function is simultaneously played. The utility model has the advantages of simple structure, long service life, low manufacturing cost, high production efficiency, etc.
Description
Technical field
The utility model relates to a kind of diel, relates in particular to a kind of mould structure that the counterbore on the long pole is carried out plastic working with the side direction limit method.
Background technology
Stock class part width, thickness are little, and length is but very long, is applied to building materials, automobile, electric utility more.For fixing and the needs that are connected, on the stock class part counterbore to be arranged.According to the rule and the practice of Metal Forming, when counterbore was shaped, part metals can be to the counterbore flows outside.And the metal flow resistance of long rod part width is less than the metal flow resistance of length direction, and is therefore bigger in the flow of metal of width, needs side direction spacing.The method of processing counterbore has following several at present:
Method one: directly process with cutting working method;
Method two: the manually single operation substep of feeding drawing;
Method three: with behind the progressive die pre-punched hole, at next work step with drift with the counterbore drawing.
Facts have proved that the stock utilization of method one and production efficiency are all very low, only adopt when trial production.The precision of method two is relatively poor, and production efficiency is very low.Method three is a kind of new manufacturing process, and with the parts size precision height that it is shaped, stock utilization height, die life, height was highly efficient in productivity.But it is spacing that a kind of special mould structure of its needs carries out side direction.
The utility model content
The technical problems to be solved in the utility model provides a kind of side direction position limiting structure of long pole diel, can limit the variation of its width dimensions when the long rod part counterbore, and simple in structure, cost is lower.
In order to solve the problems of the technologies described above, the utility model provides a kind of side direction position limiting structure of long pole diel, comprise upper die and lower die, described patrix is equipped with drift, it is characterized in that described patrix vertical fixing has at least one pair of side direction spacer pin, each side direction spacer pin all has a straight flange, be installed in the both sides of described drift in twos relatively, the spacing that two relative straight flanges are asked is the width of described long pole.
In the above-mentioned mould, described patrix can comprise upper bolster, punch retainer, blank holder, and described side direction spacer pin is fixed on the described punch retainer and stretches out described blank holder.
In the above-mentioned mould, described counterdie has a plurality of resigning holes corresponding to the position of described side direction spacer pin.
In order to play the effect of side direction correcting simultaneously, in the above-mentioned mould, also has one section before the straight flange of described side direction spacer pin to the tip of extending away from the drift direction.
As from the foregoing, the utility model provides side force by the side direction spacer pin that is installed in the upper mould fixed plate for counterbore is shaped, guarantee long rod part width dimensions no change, also can play the effect of side direction correcting simultaneously, and have simple in structure, life-span height, low cost of manufacture, the production efficiency height, advantage such as the counterbore pattern that processes is attractive in appearance.

Fig. 2 is the vertical view of the utility model embodiment long pole diel counterdie;
The local enlarged diagram of position limiting structure when Fig. 3 is the utility model embodiment punching press.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
The side direction position limiting structure of present embodiment long pole diel is made up of counterdie and patrix, as depicted in figs. 1 and 2: lower bolster 2 and concave template 3 are fixed on the die shoe 1 successively by screw and pin, two pairs of material lift nails 4 are separately fixed on the concave template 3, long pole 13 is lifted, and concave template 3 offers resigning hole 14 on the position corresponding to side direction spacer pin 11.
Punch retainer 6 and convex mould pad 7 are fixed on the upper bolster 8 successively by screw and pin, and blank holder 5 links with upper bolster 8 by discharging screw 9 and discharging spring 10, and counterbore drift 12 is contained in the punch retainer 6.Spacing in order to realize side direction, the utility model also vertically is provided with two pairs of side direction spacer pins 11 that stretch out blank holder 5 in the both sides of punch retainer 6 upper punch 12.
Please refer to Fig. 3, the side direction spacer pin 11 of present embodiment is to form after the cylinder that will have tapered end longitudinally cuts sub-fraction, remain with a bit of to the cone point that extends away from drift 12 directions in the end, play the effect of correcting long pole 13, and the straight flange after its cutting is a plane.The straight flange that makes a pair of side direction spacer pin 11 is relative thirty years of age on the position of long pole 13 both sides correspondences, and spacing is the width of long pole, just can play spacing effect.
During work, upper bolster 8 moves down, and side direction spacer pin 11 moves down thereupon, relies on its cone point with long pole 13 correctings, and stretches into gradually in the resigning hole 14.Along with upper bolster 8 continues to move down, blank holder 5 is pressed into concave template 3 with material lift nail 4,10 compressions of discharging spring, and long pole is pressed on the concave template 3 by blank holder 5.The straight portion of side direction spacer pin 11 arrives long pole 13 both sides, and counterbore drift 12 begins towards counterbore.The existence of side direction spacer pin 11 straight flanges makes the metal flow of long pole 13 widths obtain restriction, thereby reaches the physical dimension requirement of formation of parts.Punching press finishes back upper bolster 8 backhauls, and blank holder 5 lifts, and material lift pin 4 lifts long pole.The partial enlarged drawing of position limiting structure as shown in Figure 3 during its punching press.
In sum, the utility model provides side force by the side direction spacer pin that is installed in the upper mould fixed plate for counterbore is shaped, when patrix moves downward, the side direction spacer pin can play the effect of side direction correcting, patrix continues to move down, and the straight flange retaining of side direction spacer pin is on the width of stock, during towards counterbore, long rod part is owing to be subjected to the active force of side direction spacer pin, width dimensions no change.
On the basis of the foregoing description, can also do the various conversion that are equal to, be not limited to adopt shape among the embodiment as the side direction spacer pin, in addition, the upper die and lower die structure of the foregoing description is a kind of knockdown design, but the utility model is not limited thereto, and also can adopt other structures such as integral module.It is highly relevant with material lift with punching stroke etc. whether resigning hole is set.
