В полости ползуна 1 размещен пуансонодержатель 3» связанный с ним пружиной растяжения 4 и фиксируемый от поворота пальцем 5. Пуансонодержатель 3 опирается буртом 6 в торец 7 ползуна 1. На пуансонодержателе 3 соосно установлена поворотная гильза 8 со спиральным пазом Я, в котором раэме- ю щен палец 10, закрепленный в пуансонодержателе 3. На наружной боковой поверхности гильзы 8 выполнены зубцы, находящиеся в зацеплении с шестерней 11 зубчатого перебора с руч- 15 ным приводом от маховичка 12. Длина зуба на гильзе 8 такова, что обеспещивается возможность возвратно-поступа'· тельного движения ползуна 1 с пуёнсо(нодержателем 3 относительно шестерни 20 11.’ На пуансонодержателе 3 установлен пуансон 13.927423 4 binded scissors slider 1 connected to the crank drive 2. In the cavity of the slider 1 there is a punch holder 3 ”connected with a tension spring 4 and fixed from turning by a finger 5. Punch holder 3 rests with a shoulder 6 in the end 7 of the slider 1. On the punch holder 3 a rotary sleeve 8 with a spiral groove I is coaxially mounted, in which a finger 10 is fixed in the punch holder 3. On the outer side surface of the sleeve 8, teeth are engaged that are engaged with the gear wheel 11 of the manual gearbox with a 15 drive handwheel 12. The length of the tooth to the sleeve 8 such that the possibility of reciprocating obespeschivaetsya By proceeding '· relative motion of the slider 1 with puonso (noderzhatelem 3 relative to the pinion 20, 11.' 3 is mounted on the punch holder 13 of the punch.

Эффект использования предлагаемого пресса заключается в снижении трудоемкости наладки (совмещения пуансона с центром кернения) и улучшении условий ее осуществления.The effect of using the proposed press is to reduce the complexity of the setup (combining the punch with the center of punching) and improve the conditions for its implementation.

Claims

The invention relates to pressure treatment and can be used in the processing of long and flat products. . The known hole of the fixed press of the combined shears for cutting rolled products contains a slider, a punch holder associated with it and a punch axis alignment unit with a center of core, containing a pivot element connected with a manual part of a press that is kinematically connected with a manual drive; axial movement and rotation by means of a finger and a spiral groove 1 The lack of a press is associated with the need to disconnect the slider from the press drive and move it when the punch axis is aligned with the center of the ke The aim of the invention is to reduce the labor intensity of setting up. The goal is achieved by producing a punched press of combined shears for cutting rolled products containing a slider, a punch holder associated with it and a core center containing kinematically a pivot element connected to a hand drive connected to a press part associated with it with the possibility of relative axial movement and rotation by means of a pallet tsa and the helical groove, the spring is provided with a punch holder, linking it to the slide, with the independent reciprocating movement along the stamping axis, and the rotary member is a sleeve and is movably mounted on. the punch holder is coaxial with it. FIG. 1 shows a punching press, a general view; in fig. 2 is a section A-A in FIG. 1. The punching press contains a slider 1 installed in the guide frames of the combined shears and connected to the crank-knee drive 2. In the cavity of the slider 1 there is a punch holder 3i associated with it spring tension k and fixed by rotation with a finger 5. Punch holder 3 is supported by the shoulder 6 in the end 7 of the crawl on 1. On the punch holder 3 there is a coaxially mounted rotary sleeve 8 with a helical groove H in which the finger 10 is mounted, fixed in the punch holder 3. On the outer side surface of the sleeve 8 there are teeth in engagement with the gear 11 of the gear train with a manual drive from the handwheel 12. The length of the tooth on the sleeve 8 is such that it provides the possibility of reciprocating movement of the slide 1 with puynso; the holder 3 relative to the gear 11, On the plug holder 3, there is a punch 13. The press works as follows. When the handwheel 12 rotates, the sleeve 8 rotates, due to the interaction of the spiral groove 9 with the finger 10, moves the punch holder 3 with the punch 13 down to align the latter with the center of core on the workpiece (not shown). Then the handwheel 12 is released and under the action of the extended spring k of the punch holder 3 returns to the original half pack (see Fig. 2), and the bushing of the punch holder 6 rests against the end 7 of the slider 1. When the power drive of the press is subsequently turned on, the punching force is transmitted from the slider 1 through the punch holder 3 to the punch 13, to mine all the details of the node combining the axis of the punch with the center of the core. The effect of using the proposed press is to reduce the labor-intensiveness of setting up (combining the punch with the center of numericness) and improving its implementation conditions. Invention Punching machine of combined shears for cutting rolled products containing a slider, associated with it Punch holder and the node combining the punch axis with the center of the stern containing kinematically a pivot element connected to a manual drive associated with a press part mated to it. with a possibility of relative axial movement and rotation by means of a finger and a spiral groove, characterized in that, in order to reduce the labor intensity of set-up, the punch holder is provided with a spring connecting it with the slide with the possibility of independent reciprocating movement along the punching axis, and the rotating element is designed as a sleeve and is movably mounted on the punch holder coaxially with it .
