Description

Forcing press
Technical field
The utility model relates to a kind of forcing press, belongs to general press technologies field.
Background technology
At present, some medium-sized and small enterprises in order to save raw material, so that reduce production costs, adopt the method for pressure forming to make when producing bicycle middle shaft mostly, promptly through the bar of preliminary working through large pressing machine by means of the mould extrusion modling.Forcing press is selected between 300~400 tons normal pressure machine mostly, as closed type single point press commonly used.Its weak point is that the acquisition expenses of these equipment is higher, and the use of equipment, maintenance cost are also higher, and this brings inconvenience for user's use.
Summary of the invention
Technical problem to be solved in the utility model provide a kind of simple in structure, cost is low and the forcing press of reliable operation.
It is as follows to address the above problem the technical scheme that is adopted:
The utility model comprises motor, frame and transmission device, it is characterized in that said transmission device is made of the crankshaft connecting rod system that band transmission, gear drive and pair of parallel symmetry are loaded on the frame both sides, wherein, gear-driven driving gear and power transmission shaft are fixed, be the band transmission between power transmission shaft and motor, and be loaded between driven pulley on the power transmission shaft and power transmission shaft and be provided with clutch, driving gear and an identical with it idler gear are meshing with each other successively between two crankshaft toothed wheels.
The center upper portion place of said frame is equipped with a hydraulic cylinder that piston rod is downward.
Be connected with the mould mount pad on the said frame.
Forcing press provided by the utility model, adopted the double crankshaft connecting rod mechanism of parallel symmetric arrangement in its transmission device, so that be used for processing rod member or the axle part product that two ends are symmetry shape, particularly can make the special equipment of the pressure processing moulding of bicycle middle shaft.This machine tool structure is simple, cost is low, and reliable operation is low with the product cost of its pressure processing, effect height, good product quality.
Description of drawings
Fig. 1 is that the master of a kind of embodiment of the utility model looks the sectional structure schematic diagram;
Fig. 2 is the A-A cutaway view of Fig. 1;
Fig. 3 is that the dynamic model interblock of piston rod and mould adopts the hinged partial structurtes schematic diagram of spherical linkage.
In the accompanying drawings: 1 crankshaft toothed wheel, 2 bent axles, 3 bearings, 4 frames, 5 hydraulic cylinders, 6 piston rods, 7 patrixes, 8 die box, 9 dynamic models, 10 connecting rods, 11 mould mount pads, 12 driving gears, 13 power transmission shafts, 14 driven pulleys, 15 clutches, 16 motors, 17 idler gears, 18 clubs.
The specific embodiment
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing:
Referring to accompanying drawing 1,2, comprise motor 16, frame 4 and transmission device in the formation of the present utility model, it is characterized in that said transmission device is made of the crankshaft connecting rod system that band transmission, gear drive and pair of parallel symmetry are loaded on frame 4 both sides, wherein, gear-driven driving gear 12 is fixing with power transmission shaft 13,16 in power transmission shaft 13 and motor are the band transmission, and the driven pulley 14 and 13 of the power transmission shafts that are loaded on the power transmission shaft 13 are provided with clutch 15, and driving gear 12 and an identical with it idler gear 17 are meshing with each other successively between two crankshaft toothed wheels 1.
When using as the special pressure process equipment of bicycle middle shaft with this forcing press, because of constituting by die box 8, patrix 7 and left and right sides dynamic model 9 that counterdie is installed with the matching used bicycle middle shaft mould of this machine, at this moment, two connecting rods 10 in a pair of crankshaft connecting rod system respectively with the dynamic model 9 of mould homonymy hinged, also need dispose the device of control patrix 7 foldings and locking.In the present embodiment, employing be the downward hydraulic cylinder of a piston rod 5, the cylinder body of hydraulic cylinder 5 is fixed on frame 4 center upper portion places, the lower end of piston rod 6 and the patrix of mould 7 is fixing.
For the ease of installing and the matching used mould of this machine, can on frame 4, connect a mould mount pad 11.When this lathe was used as special purpose machine tool, mould mount pad 11 can be fixedlyed connected with frame 4.When this lathe was used as Do-All, mould mount pad 11 can adopt adjustable connected mode to be connected with 4 of frames.
Referring to accompanying drawing 1,2,3, forcing press provided by the utility model, its two connecting rods 10 are hinged with the left and right dynamic model 9 of mould respectively.Articulated manner can adopt the version of cylindrical hinge, as shown in Figure 1, 2.Also can adopt the version of spherical linkage as shown in Figure 3.In Fig. 3, the club 18 of spherical linkage adopts screw connection structure, the length of being convenient to regulate connecting rod 10 like this with connecting rod 10 ends.This screw connection structure is equally applicable to the connecting rod of cylindrical hinge in hinged.
Light in order to ensure machine tool running, long service life is preferably in 2 on frame 4 and bent axle and establishes bearing 3, and bearing 3 can be a rolling bearing, but preferably adopts sliding bearing.
