Description
Technical field
The utility model belongs to Cold Forging technical field, is specifically related to single many connecting rods of two point cold extruding mechanism that drives.
Background technology
Cold forging is the general designation of the plastic workings such as cold die forging, cold extrusion, cold-heading, to the processing and forming below material recrystallization temperature, be the forging of carrying out below recovery temperature, many connecting rods of the two point cold extruding mechanism relating in the utility model belongs to cold extrusion category.Cold extrusion, with respect to punching press, has the advantages such as forging mechanical performance is high, surface quality good, pollution is few, and cold extrusion is at present widely used at a lot of engineering fields.But in view of the stretching attribute of material, so the slide block operating rate of cold extrusion inevitable requirement cold extrusion press is very little, this has just caused the efficiency of cold extrusion press not high in essence.Horizontal double cold extruding mechanism (the patent publication No.: CN 101050809A that the Zhao Sheng Dun He Wang Jun of Xi'an Communications University two people propose at present, as shown in Figure 3), also be single two point cold extruding mechanism that drives in essence, but the structure that he takes is that traditional cold pressing mechanism is carried out to symmetrical distribution from crank section, because this mechanism has increased the mechanism of nearly a times compared with former cold extrusion press, so this has just caused this horizontal double cold extruding mechanism space requirement larger, two work slide blocks are difficult to synchronous, because multi-bar linkage is many, the power of cold extrusion press consumption must increase.
Summary of the invention
For the fundamental contradiction of cold-stamped job requirement and operating efficiency, in order to realize mechanism's compactness, taking into account of operating efficiency and energy resource consumption, the utility model proposes single many connecting rods of two point cold extruding mechanism that drives, and can effectively solve this contradiction.
A kind of single many connecting rods of two point cold extruding mechanism that drives, comprise drive motors, crank, fork, supercharging triangle mechanism and roll adjustment connecting rod, described drive motors is fixed on the first basic point, described crank one end is connected on the output shaft of described drive motors, one end of described fork is hinged on the second basic point, the other end of described crank, the other end of fork is hinged on respectively on two angles of described supercharging triangle mechanism, hinged described roll adjustment connecting rod on the another one angle of supercharging triangle mechanism, it is characterized by: in the lower end of described adjusting screw, be connected with a component slide block vertically moving, in the lower end of described component slide block, be connected with a component triangle mechanism, this component triangle mechanism is for take and the described component slide block isosceles triangle that is drift angle, on two base angles of isosceles triangle, by a work connecting rod, connect a work slide block respectively, and described work slide block the direction of motion vertical with the base of described isosceles triangle.
Described supercharging triangle mechanism is triangular supports or three-link mechanism; Described component triangle mechanism is triangular supports or three bar linkage structures.
The utility model passes through to connect the mode of component triangle mechanism in the lower end of component slide block, solved the special technique problem under the specific (special) requirements of this area, that is exactly the contradiction between jogging speed and large extruding force, for traditional single cold pressing mechanism or punch die that drives single output, there is not the problem of component in single mechanism of colding pressing of single output that drives, so also just not there is not the problem of support stiffness and the resistance to deformation of minute force mechanisms, what punch die leaned on is that the lower momentum producing makes workpiece deformation at a high speed, so the support stiffness of minute force mechanisms is required to be starkly lower than the mechanism of colding pressing of the present utility model, the utility model triangle mechanism has solved the non-deformability of cold pressing work stability inferior and continuous action power.
The utility model has the advantage of:
(1) by utilizing component slide block and component triangle mechanism etc. cold extrusion to be become to the two point operating mechanism of left work slide block and right work slide block, effectively solved the not high problem of the ubiquitous efficiency of cold extrusion.
(2) by utilizing the mechanisms such as component connecting rod by the left work slide block of being distributed in of the stroke of component slide block, speed and acceleration equivalence and right work slide block, this has guaranteed that left work slide block, right work slide block are identical with the motion of component slide block, so can be directly by regulating roll adjustment connecting rod to complete for the pressure stroke that need to change cold extrusion press, for two point list, drive cold extruding mechanism, roll adjustment is simple, be easy to get.
(3) what component connecting rod adopted is that isosceles triangle symmetry is hinged on component slide block, and two work slide blocks are along the center line symmetric configuration of the isosceles triangle of component connecting rod, so can guarantee, in the Cold Extrusion Process of two work slide blocks, effectively to realize dynamic balancing.
