Description

A kind of miniature pneumatic forcing press

Technical field

The utility model relates to the metal-working plant of a kind of compacting, riveted joint, and it is short to relate in particular to impulse stroke, is used to rivet assembly process, and a kind of miniature pneumatic forcing press of ability instead of manual hammer.Belong to pressure forming machine.

Background technology

Existing a kind of pneumatic press, like Chinese patent open (bulletin) number: 101301796, open (bulletin) day: on November 12nd, 2008, denomination of invention: " a kind of pneumatic press ", its body comprise the support of base, cantilever and connection base and cantilever; Said base is used for fixing workpiece, and said cantilever is used for guider is fixed on the top of workpiece; Being provided with in this guider can be along its reciprocating slide block; Said slide block is by air cylinder driven; It is characterized in that said cylinder is arranged on the said support, the piston rod of said cylinder is connected through the first connecting rod that is hinged on the said body with said slide block at least.

This pneumatic press of prior art is not only broken away from the form of traditional mechanical formula forcing press, and promotes first connecting rod, second connecting rod internal structure from its cylinder; Connection to its each moving component is said good-bye, and until the labile state of cylinder in work, these are for the riveted joint assembly process of accomplishing miniature parts; Just seem that mechanism is numerous and diverse; The inconvenience maintenance, unstable working condition, the high deficiency of manufacturing cost.

Summary of the invention

The purpose of the utility model is that to overcome the mechanism of existing pneumatic press numerous and diverse, the inconvenience maintenance, and unstable working condition, the high deficiency of manufacturing cost provides a kind of simple in structure, just maintenance, stable working, and the lower miniature pneumatic forcing press of cost of manufacture.Its parts are few, and versatility is good, and standardization level is high, and Installation and Debugging are convenient, and are with short production cycle, can satisfy requirements of large-scale production.

For realizing above-mentioned purpose; The technical scheme that the utility model adopts is: a kind of miniature pneumatic forcing press, comprise base, positioning fixture, drift, cope match-plate pattern, return spring, drift fixed head, support, pivot pin, lever, cylinder, and positioning fixture, support, cylinder are installed on the described base from front to back; Cope match-plate pattern and lever are installed on the described support; Described drift is fixed in the drift fixed head, reinstalls in the bore of the punch on the cope match-plate pattern, return spring 7 described balance pivots is housed at pivot pin between drift fixed head and cope match-plate pattern; Its power arm end contacts with the piston of cylinder, and its resistance arm end contacts with the drift fixed head.

On the described support sensor is installed.

Be slidingly matched in the bore of the punch of described drift on cope match-plate pattern.

Compared with prior art, the beneficial effect of the utility model is: 1. cylinder promotes lever, and lever directly just acts on the drift, and part is few, and is simple in structure, and the standard degree is high.2. cylinder is fixed on the bottom, and cylinder baffle can not swung during work, so stable working, and Installation and Debugging are convenient.3. because part is few, simple in structure, cost is low.

Description of drawings

Fig. 1 is the structural representation (the symmetrical front portion of cope match-plate pattern 6 is removed) of the utility model;

Fig. 2 is the basic circuit sketch map of the utility model.

Among the figure: base 1, sensor 2, positioning fixture 3, workpiece 4, drift 5, cope match-plate pattern 6, return spring 7, drift fixed head 8, support 9, pivot pin 10, lever 11, cylinder 12, time relay first 13, time relay second 14, two-position four-way valve 15, air accumulator 16, switch S B.

The specific embodiment

Below in conjunction with the description of drawings and the specific embodiment the utility model is done further description, but be not restriction its protection domain.

Referring to Fig. 1, Fig. 2; A kind of miniature pneumatic forcing press of the utility model; Comprise base 1, positioning fixture 3, drift 5, cope match-plate pattern 6, return spring 7, drift fixed head 8, support 9, pivot pin 10, lever 11, cylinder 12, positioning fixture 3, support 9, cylinder 12 are installed on the described base 1 from front to back, cope match-plate pattern 6 and lever 11 are installed on the described support 9; Described drift 5 is fixed in drift fixed head 8; Reinstall in the bore of the punch on the cope match-plate pattern 6, between drift fixed head 8 and cope match-plate pattern 6, return spring 7 is housed, described lever 11 fulcrums are at pivot pin 10; Its power arm end contacts with the piston of cylinder 12, and its resistance arm end contacts with drift fixed head 8.

On the described support 9 sensor 2 is installed.

Be slidingly matched in the bore of the punch of described drift 5 on cope match-plate pattern 6.

When switch S B is closed, get into "on" position, after workpiece 4 is in place; Sensor 2 is connected time relay first 13 closures, time relay second 14 closures (time is set as required); Two-position four-way valve 15 is connected, and the gas of air accumulator 16 gets into cylinder 12, and the power arm that the piston of cylinder 12 promotes lever 11 rises; And under the effect of pivot pin 10, the resistance arm of lever 11 presses down drift fixed head 8, and it is descending that drift fixed head 8 promotes drift 5; Accomplish the processing of workpiece 4, the time relay 13 and the time relay 14 open circuit after setting-up time is accomplished, drift fixed head 8 is automatic homing under return spring 7 effects.According to difference processing needs and the running time of the setting-up time relay 13 and the time relay 14.

The connected mode of other elements in the circuit diagram such as the time relay etc. is identical with prior art, and this paper does not give unnecessary details.
