Specific implementation mode:
The utility model is described in further detail below in conjunction with attached drawing.
Embodiment 1, a kind of hand bending machine for sheet materials, referring to Fig.1, including rack 1, be fixed on the rack driving device 2, The bearing plate 6 on the output end of driving device 2 and the lower die on bearing plate 65 are fixed on, between 1 both side plate of rack It is fixedly connected with the fixed plate 3 for being parallel to lower die 5, is mounted in fixed plate 3 between fixed plate 3 and lower die 5 and under coordinating The upper mold 4 that mould 5 uses.Thin plate to be processed is placed between upper mold 4 and lower die 5, bearing plate is allowed by starting driving device 2 6 drive lower dies 5 move up, and the bending of thin plate can be completed work until thin plate is bonded with upper mold 4.
Referring to Fig.1, driving device 2 includes two hand-hydraulic cylinders 20 being installed in parallel in rack, is plugged on two respectively Drive rod 21 that two of a 20 input terminal of hand-hydraulic cylinder are placed in parallel, both ends are respectively and fixedly connected to two drive rods 21 far from hand The synchronizing bar 22 of 20 one end of hydrodynamic cylinder pressure and the driving handle 23 for being fixed among synchronizing bar 22 and being parallel to drive rod 21.It is logical Crossing pressing driving handle 23 drives two hand-hydraulic cylinders 20 to work asynchronously, and the output end of two hand-hydraulic cylinders 20 is made to synchronize It rises, and then complete the pressing thin plate of lower die 5 to make light sheet bending.
Production cost is greatly reduced since embodiment 1 is simple in structure, and utilizes means of transport after being split Take outdoor use to, construction site is in use, ground and out-of-flatness outdoors.With reference to Fig. 2, in rack 1 bottom surface four apex Height-adjustable height adjustment device 8 is set, and height adjustment device 8 includes the screwed pipe 80 for being fixed on 1 bottom surface of rack, cooperation The threaded rod 81 of the connection of screwed pipe 80 and the threaded base 82 for being threaded in 80 lower end of screwed pipe, screwed pipe 80 and screw thread bottom 82 internal threads of seat are reversed each other.The regulation handle 83 perpendicular to adjusting screw rod 81 is plugged among adjusting screw rod 81, along level side It is drawn close or separate trend to that screwed pipe 80 can be allowed to have with threaded base 82 to direction rotation regulation handle 83.Four Height adjustment device 8 is used cooperatively the height that can adjust 1 different location of rack and then makes 1 holding of rack horizontal.Under rack Square both sides are provided with spirit level 7(Referring to Fig.1), the horizontality of rack can be monitored.
In embodiment 1, if gap influences, to the precision of light sheet bending, simultaneously to increase compared with conference between upper mold 4 and lower die 5 The displacement for having added 20 output end of hand-hydraulic cylinder to move up and down, in order to preferably control the distance between upper mold 4 and lower die 5, Multiple limit holes 10 being inserted into for fixed plate 3 are offered on 1 two side of rack.Fixed plate 3 is inserted in different limit holes In 10, the elemental height that can control upper mold 4 adapts to the thin plate of different-thickness.Shorten the distance between upper mold 4 and lower die 5, drop Acting needed for low driving handle 23.
Specific implementation process, rotation regulation handle 83 adjust the height at 1 four angles of rack, and range estimation spirit level 7 allows rack 1 to protect Water holding is flat, and thin plate is attached to 4 lower section of upper mold, reciprocal to press driving handle 23, allows lower die 5 to rise, until thin plate is bonded with upper mold 4 Reach bending effect.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability Field technique personnel can as needed make the present embodiment the modification of not creative contribution after reading this specification, but As long as all being protected by Patent Law in the right of the utility model.
