Abstract
The utility model discloses a hydraulic material returning mechanism, relating to the punch machine structure technique. The utility model comprises a support base, a punch die, a guide pole and a main oil cylinder, wherein, a support spring is provided with a swaging oil cylinder; the lower end of the swaging oil cylinder body is fixedly connected with a stripper plate provided with a central hole; inner steps are arranged in the swaging oil cylinder body and support a piston die holder with clearance; the upper end of the piston die holder is provided with a locknut which is in seal connection with the swaging oil cylinder body; the punch die and the guide pole are arranged in the piston die holder; an oil passage communicated with the steps is arranged on the swaging oil cylinder body; and the outer end of the oil passage is provided with a pressure oil source. The hydraulic material returning mechanism can increase drawing force of the punch die, adjust the drawing force as required so as to adapt to different punching tonnages, eliminate the material taking phenomenon, and has good working stability and quick punch die response, can reduce the time of the whole punching process and improve the work efficiency of punch machines.
Description
Technical field
The utility model relates to a kind of structure technology of machining equipment technical field, particularly press machine.
Background technology
Be fixed with supporting seat on the lathe bed of existing press machine, interior step is set in supporting seat, at interior step is to arrange support spring, guide pin bushing is set on support spring, interior step also is set in guide pin bushing, on interior step, supports Upper Die-sleeve, in Upper Die-sleeve, arrange punch die and guide pillar by spring, and, guide pillar is arranged in the punch die top, and the master cylinder action by the guide pillar top reaches punch die by guide pillar with stamping press, make punch die to the workpiece punching press, form punching, remove the master cylinder oil pressure, under the effect of spring, Upper Die-sleeve upwards resets, and it is up to drive punch die.When manufacturing and designing automobile longitudinal girder numerical control flat board flexible unit, when finding the large-tonnage punching press, the withdrawing pattern power of mould is very big, is difficult to solve by spring, can not reset, and influences next punching press action.
The utility model content
The utility model purpose is to design a kind of hydraulic pressure unloading mechanism with big patrix withdrawing pattern power.
The utility model comprises supporting seat, punch die, guide pillar, master cylinder, interior step is set in supporting seat, on interior step, support spring is set, described guide pillar is arranged in the top of punch die, the upper end of guide pillar is arranged in the mesopore top of locking nut, arranging master cylinder above the guide pillar, on frame, the expansion link of described master cylinder is arranged on the top of guide pillar; The binder oil cylinder is set on support spring, the fixedly connected stripper that is provided with mesopore in the lower end of described cylinder body of material press oil cylinder, interior step is set in the cylinder body of binder oil cylinder, gap support piston die holder on interior step, the upper end of piston die holder is provided with locking nut, be sealedly and fixedly connected between the cylinder body of described locking nut and binder oil cylinder, described punch die and guide pillar are arranged in the piston die holder; The oil duct that is communicated with its step is set on the cylinder body of binder oil cylinder, pressure oil-source is set in the outer end of oil duct.
Pass through pressure oil-source, make the cylinder body of piston die holder, binder oil cylinder form one, when master cylinder refuels, it is descending that the descending guide pillar that stresses on of piston rod, the cylinder body that drives the binder oil cylinder by guide pillar overcome the elastic force of support spring, makes the stripper suppressing action in workpiece, at this moment, master cylinder continue to refuel, and it is descending with respect to cylinder body of material press oil cylinder to make guide pillar and punch die drive the piston die holder, and the mesopore of punch die by stripper acts on realizes punching press on the workpiece.Continue to give the pressurization of binder oil cylinder oil sources, the piston die holder is up, on pull out guide pillar and punch die, this moment, stripper still acted on the workpiece, last master cylinder oil pressure off-load, and piston rod is up, under the effect of support spring, whole binder oil cylinder is up, drives the up workpiece that leaves of stripper, waits for punching press next time.
The utility model can strengthen the withdrawing pattern power of punch die by oil sources, also can adjust withdrawing pattern power size as required, to adapt to different punching press tonnages, has stopped the generation of band material phenomenon.The utility model good operating stability, punch die is replied fast, can reduce the omnidistance time spent of punching press, improves the stamping machine operating efficiency.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, counterdie 14 is arranged in the below of workpiece 7, fixedly connected supporting seat 4 on frame, interior step is set in supporting seat 4, support spring 13 is set on interior step, the binder oil cylinder is set on support spring 13, the lower end of cylinder body of material press oil cylinder 2 is bolted to connection the stripper 6 that is provided with mesopore, interior step also is set in cylinder body of material press oil cylinder 2, gap support piston die holder 11 on interior step, the upper end of piston die holder 11 is provided with locking nut 10, and locking nut 11 is fixedlyed connected by screw thread with cylinder body 2 upper ends of binder oil cylinder, also is provided with sealing ring between the two.
Punch die 12 and guide pillar 1 are set in piston die holder 11; Guide pillar 1 is arranged in the top of punch die 12, and the upper end of guide pillar 1 is arranged in the mesopore top of locking nut 10, arranges master cylinder 9 above guide pillar 1, on frame, and the expansion link of master cylinder 9 is arranged on the top of guide pillar 1.
The oil duct that is communicated with its step is set on the cylinder body 2 of binder oil cylinder, pressure oil-source 8 is set in the outer end of oil duct.
In addition, between cylinder body of material press oil cylinder 2 and supporting seat 4, also be provided with guide pin bushing 3,5.
