Wherein: 1 gantry type frame, 2 hydraulic cylinders, 3 jumper bars, 4 drifts, 5 perforating dies, 6 punching bases, 7 longitudinal delivery mechanisms, 8 spacing decks, 9 terminal pads, 10 punching vertical slots, 11 lifting hitching posts, 12 notches, 13 secondary pin-and-holes, 14 kingpin bores.
Detailed description of the invention
Below in conjunction with accompanying drawing, further detailed description is done to the utility model:
As shown in Figure 1, a kind of machine tool for punching of the present invention, comprises gantry type frame 1, is provided with punching actuating unit above gantry type frame 1, and punching actuating unit can adopt hydraulic cylinder 2, arranges plunger rod in hydraulic cylinder 2, and jumper bar 3 is vertically connected to below plunger rod.Vertically stretching up and down of jumper bar 3 is realized under the driving of hydraulic cylinder 2.Jumper bar 3 top is provided with the terminal pad 9 with bolt hole, convenient installation.Be provided with perforating die 5 below jumper bar 3, bottom perforating die 5, be provided with punching base 6, below punching base 6, be provided with the connecting gear that can drive punching base 6 longitudinal translation.
As shown in Figure 2, perforating die 5 is cylindrical, perforating die 5 center have up/down perforation and upper end open can be just right with jumper bar about 3 punching vertical slot 10, punching vertical slot 10 is taper shape wide at the top and narrow at the bottom, and punching vertical slot 10 base diameter is greater than jumper bar 3 or drift 4 diameter.Perforating die 5 side-wall outer side is provided with lifting hitching post 11, convenient lifting perforating die 5.
Punching base 6 is provided with some spacing decks 8, perforating die 5 is placed between the spacing deck 8 on punching base 6, and spacing deck 8 counter-punching die 5 plays positioning action.Spacing deck 8 is right angled triangle, and a right-angle side of spacing deck 8 is fixed on punching base 6, and another right-angle side is close to perforating die 5 lateral wall, and is provided with the cambered surface seamlessly transitted between spacing deck 8 top apex and right-angle side.
As Fig. 3, shown in 4, jumper bar 3 is in downward punching course, the stamping press that the bottom of jumper bar 3 is subject to is maximum, the most easily damage, therefore the independently drift 4 of different size is devised, as required the drift 4 of suitable specification is arranged on jumper bar 3 bottom, jumper bar 3 and drift 4 adopt and removably connect, particularly, jumper bar 3 bottom is provided with horizontal kingpin bore 14, drift 4 is cylindrical, drift 4 top center has draw-in groove, the sidewall of drift 4 has two back to notch 12, on notch 12, lateral direction penetrating has the secondary pin-and-hole 13 through draw-in groove, in the draw-in groove that jumper bar 3 bottom penetrates drift 4 and kingpin bore 14 is installed with bearing pin after aliging with secondary pin-and-hole 13 jointly.
Its operation principle is: be bolted on plunger rod by the terminal pad 9 of jumper bar 3, is lifted between the spacing deck 8 be placed on punching base 6 by perforating die 5, thus completes the assembling of equipment.Punching base 6 and perforating die 5 move to outside gantry type frame 1 by longitudinal delivery mechanism 7, then the round steel burning heat is vertically put into the punching vertical slot 10 of perforating die 5, punching base 6 and perforating die 5 move to below gantry type frame 1 by connecting gear again, make the center of jumper bar 3 just to the center of punching vertical slot 10, then hydraulic cylinder 2 promotes jumper bar 3 downwards, jumper bar 3 stretches into downwards in punching vertical slot 10 and also continues along the downward punching press in round steel center, stop when jumper bar 3 is stamped down to certain depth, due to shutoff bottom punching vertical slot 10, held bottom round steel, and be unlikely to penetrate, thus complete the punching press of blind hole.Because punching vertical slot 10 is taper shape wide at the top and narrow at the bottom, in the punching course of blind hole, round steel is when being subject to the stamping press of jumper bar 3, can from bottom along punching vertical slot 10 inwall to overflow, because punching vertical slot 10 inwall smoother is smooth, after final punching press completes, also smoother is smooth for the outer surface of round steel.
The present invention can improve on the basis of quick forging machine, utilizes the original gantry type frame 1 of quick forging machine, hydraulic cylinder 2, longitudinal delivery mechanism 7 etc.The diel of quick forging machine pulled down, replace with the jumper bar 3 of this patent, perforating die 5, punching base 6, dismounting is more convenient, also achieves a tractor serves several purposes, has saved cost.
The above is only the preferred embodiment of this patent; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the art of this patent principle; can also make some improvement and replacement, these improve and replace the protection domain that also should be considered as this patent.
