Abstract

The utility model relates to a positioning device for a punching machine, comprising a feeding platform with a lower die, and a lifting handpiece that is arranged on the platform and used for driving an upper die to conduct punching. The positioning device is characterized in that a plurality of axial elastic telescopic rods used for blocking the punching workpiece to be machined from advancing are arranged on the feeding platform at the front side and at the rear side of the lower die in longitudinal direction; pressing rods arranged in the extension lines of the axial elastic telescopic rods are arranged correspondingly on the handpiece; and each pressing rod is a rod or a fine rod with the forwards inclined surface arranged at the lower end so as to lead the forwards moving punching workpiece to be machined to press the axial elastic telescopic rods during the reciprocating process along with the handpiece before or after punching. The positioning not only plays the roles in initially blocking and positioning automatically and automatically blocking and positioning during subsequently punching process, but also has simple structure, can be used convenient (only needing to push forwards the punching workpiece to be machined), does not waste material, can position precisely, and can realize automatic production without special feeding equipments.

Description

The positioner that stamping machine is used

Technical field

The utility model relates to the positioner that a kind of stamping machine is used, and is applicable to that machine-building (punching, diel) needs to locate, the field of backgauge.

Background technology

In the existing punch process, material in mould the location or backgauge except that adopting special-purpose feeder equipment, the side edge spacing structure is arranged, though the convenient waste material of punching; Initial backgauge nail is arranged, need manual operations; The backgauge nail that is located at counterdie is arranged, need raw material is lifted and could follow closely by backgauge behind each stamping-out; The deficiency of these structures causes cost of stamping height, work efficiency low.

Summary of the invention

The positioner that provides a kind of stamping machine to use is provided the purpose of this utility model, not only can play the continuous punching production that automatic initial backgauge location and follow-up punching press automatic catch are anticipated the position effect, are convenient to manual feeding or motor-driven feeding simultaneously, and simple in structure, easy to use, not waste material, location accurately, need not special-purpose feeder equipment and also can realize automatic production.

Its solution is: the positioner that a kind of stamping machine is used, comprise the feeding board that counterdie is installed and be located at being used on the board drive the lifting head that patrix carries out press work, it is characterized in that: on the feeding board that is positioned at side before and after the counterdie, be used to block the axial elasticity expansion link that the punching press workpiece to be machined moves ahead along vertically several being installed; The corresponding depression bar that is positioned on the axial elasticity expansion link extension line that is provided with on the described head; Described depression bar is that lower end is provided with the bar on the inclined-plane that leans forward or for thin bar so that depression bar before or after punching press with in the reciprocal process of head, allow the punching press workpiece to be machined that shifts forward push down the axial elasticity expansion link.

Compared with prior art, advantage of the present utility model is: the one, adopt the work that matches between depression bar and the axial elasticity expansion link, can play automatic positioning action to initial backgauge and follow-up backgauge simultaneously, also be suitable for the location of semi-finished product or single-piece and the interval and other location, the indexing mechanism etc. that go out part, semi-finished product or single-piece feeding automatically simultaneously; The 2nd, adopt depression bar and axial elasticity expansion link (spring and match with spring rod member) on the structure, simple in structure, easy to use, waste material, location are accurately.

The specific embodiment

The positioner that stamping machine of the present utility model is used, comprise the feeding board 2 that counterdie 1 is installed and be located at being used on the board 2 drive the lifting head 4 that patrix 3 carries out press work, it is characterized in that: several longitudinally are installed on the feeding board 2 that is positioned at counterdie 1 front and back side are used to block the axial elasticity expansion link 6 that punching press workpiece to be machined 5 moves ahead; The corresponding depression bar 7 that is positioned on axial elasticity expansion link 6 extension lines that is provided with on the described head 4; Lean forward for lower end the is provided with bar on inclined-plane 8 or for thin bar of described depression bar 7 so that depression bar 7 before or after punching press with in the head 4 reciprocal processes, allow the punching press workpiece to be machined 5 that shifts forward push down axial elasticity expansion link 6.

With reference to figure 1～Fig. 7, head is provided with the stripper 9 that moves with head, can be provided with back-moving spring 10 in movable vertically axial elasticity expansion link 6 lower ends, plays earlier the backgauge effect before the punching press; At (or punching press workpiece to be machined 5 pushed down before) depression bar 7 before the punching press process of moment axial elasticity expansion link 6 is pushed away the section of punching press workpiece to be machined 5 along pressing direction, depression bar 7 or play the backgauge positioning action simultaneously by stripper 9.

The backgauge face 11 of axial elasticity expansion link 6 and the inclined-plane 8 of depression bar 7 produce a dislocation value 12 contacting the end (see figure 4) that misplaces each other, and in face of the punching press workpiece to be machined 5 of feeding, the backgauge face 11 of axial elasticity expansion link 6 is preceding, the inclined-plane 8 of depression bar 7 after.There is the dislocation value 12 of 0.2mm also enough during practical application.

In (or punching press workpiece to be machined 5 pushed down before) before the punching press transients by stripper 9, and after the punching press transients is finished and before axial elasticity expansion link 6 do not run into punching press workpiece to be machined 5, allow punching press workpiece to be machined 5 sections near the inclined-plane 8 of depression bar 7, make these punching press workpiece to be machined 5 sections cross the backgauge face 11 of axial elasticity expansion link 6, realize bearing down on one of punching press 5 pairs of axial elasticity expansion links 6 of workpiece to be machined, produce a mistake top value 13(and see Fig. 4), make punching press workpiece to be machined 5 on axial elasticity expansion link 6 end faces, slip over (see figure 7).When adopting other fine positionings, depression bar 7 lower ends can be made as faces 14 directly, or depression bar 7 be thin bar (see figure 5), and at this moment, dislocation value 12 equates with mistake top value 13.In the actual production, push away from start to finish or draw punching press workpiece to be machined 5 to get final product, when adopting other fine positionings or depression bar 7 lower ends to be made as inclined-plane 8, this pushing away is flexible (or intermittently), to guarantee to move after punching press workpiece to be machined 5 can omit (have 0.02mm to dislocation value 12 or to cross top value 13 also enough).

Backgauge face 11 shapes of axial elasticity expansion link 6 and the section configuration at punching press workpiece to be machined 5 backgauge places match, and can increase contact area.Axial elasticity expansion link 6 end faces can be made into and are beneficial to inclined-plane 15 or the knuckle that punching press workpiece to be machined 5 slides.

The utility model embodiment 1 is used for automatic initial backgauge location and follow-up punching press automatic catch and anticipates the position effect with reference to figure 8, its machining shape 16, and the installation site 17 of axial elasticity expansion link 6 and depression bar 7, its lateral register is 18,19; Embodiment 2 is with reference to figure 9, its machining shape 20 when being used for single-piece backgauge and location, the installation site 21 of axial elasticity expansion link 6 and depression bar 7.

The utility model is novel, and is reasonable in design, has bigger promotional value.
