Description

The upper block 11 is fastened to traverse 9 through the intermediate support 10. The lower block 12 is fixed to the cross bar 7 through the intermediate rack 13, the upper 14 and lower 15 stamps are fixed to the corresponding blocks 11 and 12. The plungers 16 of the cylinders 2 and the plungers of the forcing cylinders (not Psiazans) are connected to the grass 9 by means of spherical supports 9. Fastening is carried out with staples 18. Filling tanks 19 are located above the zip-ups 2 and filling valves 2O are located inside the hollow. The differential cylinder 21 is located in the center of the cross beam 6. The upper plunger 22 of this cylinder is attached to the central part of the return cross bar 23, the ends of which are connected to the two B5 plungers of the linear cylinders entering the cross beam 6 (not shown). The return cylinders are located in a plane perpendicular to the front of the press. The lower plunger 24 of the cylinder 21 has a flange 25, which, with the upper position of the plunger 24 relative to the crosshead 9, abuts the lower end of the adjusting sleeve 26 screwed into the flange 27 fastening in the crossmember 9. The upper piston holder 28 is attached to the plunger 24. Inside the crosshead is 9 and the stand 10 an upper ejection mechanism 29 is placed. In the lower traverse 7, a ZO cylinder is installed under the VZ cylinder, the piston rod 31 of which is attached to the supporting traverse 32. The latter is rigidly connected with the traverse 7. With the help of two columns A adjusting nut 33, against which the pins 34 are screwed into the cylinder 30. Inside the crosshead 7 and the post 13 is placed the lower ejection mechanism 35. The horizontal frame 3 sets on the lower crossbar 7. The left and right fixed crosshead 36 are connected by two columns 37 the lower one is located in the front, in front of the block of fastening of the strain, and the upper one - in the back, behind the block. Mobile columns are mounted on the columns on a sliding fit, to which horizontal punch holders 39 are attached. Rods 4O of pistons of cylinders 5 and pistons 41 of cylinder 4 are attached to the outer side of each crosshead 38, and the upper and lower blocks for fastening the straps and also, the upper and lower ejection mechanisms are similar, therefore, only nuke elements are described below. The bottom punch 15 of crepe pc on the bottom blzhe 12 using avuk pairs of wedges 42 moved along the axis by screws 43. Between the control of one side and end of the punch and block 12, steel gaskets 44 are installed. A heating induction plate 45 is placed between the punch and bottom unit 12. Through the central hole in the stamp passes the lower Bej) THKanbHbu. punch 46, covered by ejector sleeve 47. The punch is screwed into the spacer 48, which is attached to the lower punch holder with two half-rings 49 and 50. The sleeve 47 with its lower, thickened end is attached to the glass 51 using a ring 52 and 53 screws. 51 enters the central hole in the ejector beam 54 and is fastened to the last nuts with nuts 55. The ends of the cross member 54 are connected to the piston rods 56 of the hydraulic cylinders 57. Adjusting nuts 58 are screwed onto the rods 56, fixed by lock nuts 59. The work of the press follows yu way. After installation of the workpiece in the lower die 15, the presser bar 9 is lowered. High-pressure liquid is fed into the boost cylinders and simultaneously into the return cylinders, i.e. the lowering of the traverse 9 occurs with back pressure from the return cylinder. In accordance with this, the plunger 24 of the cylinder 21 occupies the upper position relative to the crosspiece 9 when it is lowered. After the dies 14 and 15 are closed, liquid is supplied to the pressing cylinders 2 and the dies are pressed. Then the working stroke of the punches begins. Sequence of movement. Anson is determined by the selected mode of operation. At the beginning of the movement of the mobile traverse 38 (at the first step of the force), the liquid is supplied only to the side cylinders 5, a rapid movement of both horizontal punches occurs. At the end of the stroke (at the second stage of the effort), the fluid is simultaneously supplied to the side 5 and central 4 cylinders. The stamping by the vertical punches 46 is carried out when the liquid is supplied to the respective cylinders 21 or 30 or to both cylinders simultaneously. After punching is complete, the punches complete the return stroke. Then, the traverse presser rises and the workpiece is pushed out of the upper and lower tampons (both ejection mechanisms 29 and 35 work). Formula Neither Hydraulic Press containing horizontal piercing system, including

two piercing cylinders with a plunger and attached to them tusans moving towards each other in the plane of the punch connector; and a vertical opposing system, including two piercing cylinders with punches moving towards each friend of the zougou, characterized by the TTTO, in order to expand technological capabilities and increase productivity qpecca, the upper and lower punches of the pulpless piercing system are equipped with eject; LI mi, made in the form of established

with the ability to move on the punches of the sleeves n attached to them, cross-sections, associated with two knitted hand glasses.
