Abstract
The utility model relates to an automatic unloading device of a punching machine. The automatic unloading device comprises a cutter, a lower mold block and a movable loading strip, wherein the cutter is installed in a lower mold base, the lower mold block is arranged in the cutter, and the loading strip is arranged at the tops of the lower mold block and the cutter. The automatic unloading device is characterized in that an oil cylinder and a connecting bolt sleeved with a spring are arranged in the lower mold block, an ejector rod of an air cylinder is connected with the bottom face of the loading strip in an abutting-against mode, the loading strip is connected to the upper end of the connecting bolt, and the top face of the loading strip is a slope face. The loading strip can be ejected out of an upper opening of the cutter through ejection of the air cylinder, products after rib cutting slide down to be unloaded depending on the dead loads, the production efficiency is high, the safety performance is good, and the operation labor intensity is low.
Description
Technical field
The present invention relates to a kind of automatic discharge device for punching machine, belong to punch press and cut muscle technical field of mold.
Background technology
In slim plate type small-power full wave bridge rectifier part production process, adopt punch press to shear the rear band of encapsulation lead frame semi-finished product, to isolate individual particle product.Muscle mould shearing is manually cut in the common employing of prior art, during operation, workman will being placed on the material containing bar in the middle of mould with lead frame semi-finished product muscle to be cut, then the matched moulds of starting shooting is cut muscle, cut product proper alignment after muscle on material containing bar, after die sinking, with hand, the material containing bar that product is housed is taken out and poured in Material collecting box for harvesting, thereby complete, once cut muscle operation.
But because each operation all will reach hand in the middle of mould, careless slightly, hand will come to harm, potential safety hazard is serious; Manually feeding needs certain hour simultaneously, has reduced production efficiency, and charging, feeding, batch turning operate and will repeat nearly ten thousand subjobs for one day, requires energy to concentrate, and does not make mistakes, and labor strength is large.
Summary of the invention
The object of this invention is to provide a kind of automatic discharge device for punching machine, make that its production efficiency is high, security good, operation labour intensity is low.
For achieving the above object, the utility model provides a kind of automatic discharge device for punching machine, it comprises the lower module being provided with in the cutter that is arranged in die shoe, cutter and is located at lower module and the upper mobilizable material containing bar in cutter top, it is characterized in that: in described lower module, be provided with the connecting bolt that oil cylinder and cover have spring, ejecting rod of cylinder apical grafting material containing bar bottom surface, two connecting bolt upper ends connect respectively material containing bar, and material containing bar end face is inclined-plane.
Further, the oblique interior angle a of described material containing bar end face is 60 °-70 °.
Further, in described lower module, be provided with three cylinders and two connecting bolts with spring.
Useful technique effect of the present utility model is: during its work, by cylinder, push that material containing bar can be ejected to cutter suitable for reading, make to cut product after muscle and rely on deadweight to slide to unload, have that production efficiency is high, security good, operation labour intensity is low.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Fig. 2 is A-A sectional structure schematic diagram in Fig. 1.
Fig. 3 is the structural representation of material containing bar and lower module in Fig. 1.
The specific embodiment
Accompanying drawing marking explanation: 1-material containing bar, 2-lower module, 3-cylinder, 4-connecting bolt, 5-product, 6-cutter, 7-die shoe, 8-spring, the oblique interior angle of a-material containing bar end face.
Below in conjunction with embodiment, be further described in detail.
As depicted in figs. 1 and 2, a kind of automatic discharge device for punching machine, comprise the lower module 2 being provided with in the cutter 6 that is arranged in die shoe 7, cutter 6 and be located at lower module 2 and the cutter 6 upper mobilizable material containing bars 1 in top, in described lower module 2, being provided with cylinder 3 and cover has the connecting bolt 4 of spring 8, ejecting rod of cylinder apical grafting material containing bar 1 bottom surface, two connecting bolt 4 upper ends connect respectively material containing bar 1, and material containing bar 1 end face is inclined-plane.During its work, cylinder 3 after ventilating ejects material containing bar 1 to cutter 6 suitable for reading, and the product 5 of cutting after muscle slides and unloads with regard to dependence deadweight, ventilates and finishes the reset under spring 8 acts on of rear material containing bar 1.
In the utility model, described material containing bar end face oblique angle a is 60 °-70 °.In described lower module 2, be provided with three cylinders 3 and two connecting bolts 4 with spring 8, and two connecting bolts 4 with spring 8 are located at respectively between two cylinders 3, two connecting bolt 4 upper ends all connect material containing bar 1, the movable apical grafting material containing of ejecting rod of cylinder bar 1 bottom surface.The up and down stability of material containing bar 1 is better like this.
During the utility model work, can push material containing bar 1 is ejected to cutter suitable for reading by cylinder 3, make to cut product after muscle 5 and rely on deadweight to slide to unload, good operation safety like this, production efficiency can promote nearly 50%, reduced workman's operating time and step, operation labour intensity reduces greatly.
During operation, material containing bar 1 is placed between lower module 2 and cutter 6, then the band lead frame semi-finished product product 5 of muscle to be cut is placed on material containing bar 1.Press punch press shift knob, upper and lower mould matched moulds completes semi-finished product and cuts muscle, and when die sinking, cylinder 3 ventilation under PLC controls, will raise out the suitable for reading of cutter 6 on material containing bar 1; Several seconds exhaust hood 3 ventilation finishes, and under back-moving spring 8 effects, material containing bar 1 is got back to home position, the product after cutting muscle and completing just on cylinder 3, push away with reseting procedure in from inclined-plane, skid off and fall Material collecting box for harvesting, thereby realize semi-finished product to be cut, cut automatic discharging after muscle.
Should be understood that: above-described embodiment is just to explanation of the present utility model, and any innovation and creation that do not exceed within the scope of the utility model connotation, within all falling into protection domain of the present utility model.
