Abstract
The invention relates to an upper punch adjusting mechanism for a forming machine. The upper punch adjusting mechanism comprises a main driving mechanism allowing an upper punch to move up and down, and an auxiliary driving mechanism for adjusting the upper punch to enter a mold cavity in depth, wherein the auxiliary driving mechanism is externally arranged at an upper punch part. The upper punch adjusting mechanism provided by the invention has the advantages that: (1) the upper punch adjusting mechanism comprises the main driving mechanism and the auxiliary driving mechanism, the main driving mechanism coarsely adjusts the upper punch position, so that the upper punch reaches to a certain position; the auxiliary driving mechanism finely adjusts the upper punch position, so that the upper punch moves to a certain position, and such mode can achieve the accurate adjustment of upper punch strokes; (2) the displacement of up and down movement of the upper punch can be detected by an encoder, the upper punch can be accurately adjusted in place by the encoder, and the adjustment mode is simple and accurate; (3) through skillful combination of a telescopic mechanism, a worm and worm wheel mechanism and the like, the upper punch strokes can be accurately and quickly adjusted.
Description
Technical field
The present invention relates to a kind of forming machine upper punch guiding mechanism, it is applied in the compressing technical field of sintered metal product part.
Background technology
Powder metallurgic forming machines, when the pulverulent product of dissimilar, the different-thickness of processing, according to the difference of institute's fabricated product, need to be adjusted upper punch stroke.
Existing upper punch stroke is adjusted mode and generally upper punch stroke is adjusted utilizing on the basis of existing driving mechanism, and it is larger that this kind adjusted mode error, and goods this kind mode higher for some requirement on machining accuracy can not meet processing request; Or now carry out the adjustment of upper punch stroke by the modes such as pad are set in mould, this kind of mode effect is better, but comparatively complicated, waste time and energy, affect working (machining) efficiency.
Summary of the invention
The present invention is directed to above-mentioned defect, object is to provide a kind of forming machine upper punch guiding mechanism of accurately upper punch stroke being adjusted simple in structure, convenient.
The technical solution used in the present invention is for this reason: the present invention includes and make the main driving mechanism that upper punch moves up and down and adjust the secondary driving mechanism that upper punch enters cavity depth, described secondary driving mechanism is placed on upper punch setting.
Described secondary driving mechanism comprises motor (1), motor (1) connects a telescoping mechanism by transmission mechanism, telescoping mechanism drives upper punch to adjust ball screw (11) by worm screw (6), worm gear (10) and moves up and down, then by upper traveller (12), drive upper punch motion, described motor (1) arranges encoder (2).
Described transmission mechanism comprises bevel gear pair (3) and power transmission shaft (4), power transmission shaft (4) by universal slip joint (5) by transmission of power to worm screw (6).
Described main driving mechanism: comprise with described upper punch and adjust the connecting rod (9) that ball screw (11) is connected, it is upper that connecting rod (9) input is connected to a bent axle (8), and bent axle (8) drives rotation by gear (7).
Advantage of the present invention is: 1) the present invention includes a main driving mechanism and a secondary driving mechanism, main driving mechanism carries out coarse adjustment to upper punch position, makes to be flushed to certain position; Then by secondary driving mechanism, it is carried out to accurate adjustment, make upper punch move to definite position, this kind of mode can realize the accurate adjustment of upper punch stroke;
2) the present invention detects by encoder the displacement that upper punch moves up and down, and operator only need just can adjust upper punch to the right place accurately by encoder, and adjustment mode is simply accurate;
3) the present invention is by adopting telescoping mechanism, worm-and-wheel gear, by the ingenious cooperation of each mechanism, the accurate adjustment of the present invention to upper punch stroke, can reach adjustment accurately, effect efficiently.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is the side view of Fig. 1.
In figure, 1 is that for encoder, 3, for bevel gear pair, 4, for power transmission shaft, 5, for universal slip joint, 6, for worm screw, 7, for gear, 8, for bent axle, 9, for connecting rod, 10, for turbine, 11, for upper punch, to adjust ball screw, 12 be upper traveller to motor, 2.
The specific embodiment
The present invention includes and make the main driving mechanism that upper punch moves up and down and adjust the secondary driving mechanism that upper punch enters cavity depth, described secondary driving mechanism is placed on upper punch setting.
Described secondary driving mechanism comprises motor 1, motor 1 connects a telescoping mechanism by transmission mechanism, telescoping mechanism drives upper punch to adjust ball screw 11 by worm screw 6, worm gear 10 and moves up and down, and then by upper traveller 12, drives upper punch to move, and described motor 1 arranges encoder 2.
Described transmission mechanism comprises bevel gear pair 3 and power transmission shaft 4, power transmission shaft 4 by universal slip joint 5 by transmission of power to worm screw 6.
Described main driving mechanism: comprise with described upper punch and adjust the connecting rod 9 that ball screw 11 is connected, connecting rod 9 inputs are connected on a bent axle 8, bent axle 8 drives rotation by gear 7.
The course of work of the present invention is: the present invention is first by actuating unit driven gear 7, gear 7 driving crank 8 rotations, and then drive the connecting rod 9 being installed on bent axle 8 to move up and down, and then drive upper punch adjustment ball screw 11, upper traveller 12 to move up and down, above-mentioned steps realizes the coarse adjustment of upper punch.
After above-mentioned coarse adjustment, upper punch is carried out to accurate adjustment, the steps include: that motor 1 passes motion to worm screw 6, turbine 10 by bevel gear pair 3, power transmission shaft 4, universal slip joint 5, the screw thread pair that turbine 10 and upper punch are adjusted 11 of ball screws changes rotatablely moving of turbine 10 into upper punch adjustment ball screw 11 move up and down, thereby realize the accurate adjustment to upper punch, realize the adjusting that upper punch enters cavity depth.And the control of this regulated quantity and metering are by the feedback of this fine-tuning mechanism, by encoder 2 collection signals, send into programming Control system, realize setting, the control of upper punch adjustment amount and adjust and data demonstration; Thereby by this mechanism, reach the object of flexible adjustment upper punch stroke.
