Abstract

The utility model discloses a knife die setting mechanism of a blanking machine with a rocker arm. The setting mechanism comprises a fixed frame, a swinging rod, a connecting rod, a guide rod, a collision block, a hand wheel, a locknut, a tension spring, a sliding block, a support frame, a micro switch or a sensor, etc. One end of the fixed frame is fixed at the rear side of a machine body, and the other end extends to the top end of a main shaft of the rocker arm; the end part of the fixed frame is provided with a pin hole connected with the swinging rod; the other end of the swinging rod is provided with the guide rod in a fixed way; the connecting rod is connected with the swinging rod and the rocker arm; the sliding block slides on the guide rod; the hand wheel is connected with the sliding block in a threaded way, and the end part of the hand wheel leans against the guide rod; the collision block and the sliding block are connected with each other in a threaded way and are locked by the locknut; the tension spring is arranged in the guide rod, one end of the tension spring is fixed at the top part of the guide rod, and the other end of the tension spring is fixed on the support frame; the support frame is fixed at the front end of the rocker arm; and the micro switch or the sensor is fixed on the support frame. The positions of cutting-off points can be easily adjusted after the hand wheel is loosened; cutting dies with the same height can be universal after one-step setting no matter what cutting area (within the tonnage range of the blanking machine with the rocker arm) of the cutting dies is; therefore, the production is greatly convenient and the production efficiency is improved.

Description

The cutting die sets mechanism of rocking arm blanking machine

Technical field

The utility model relates to the rocking arm blanking machine that light industry generally uses, especially the cutting die sets mechanism of rocking arm blanking machine.

Background technology

The rocking arm blanking machine has flexible operation; take up an area of little; characteristics such as equipment investment is few; past often is the equipment of small business's first-selection; upgrade fast because of product now; some large enterprises also use the small lot batch manufacture of rocking arm blanking machine as new product in a large number; the course of work of conventional rocker blanking machine is: rocking arm descends fast; arrive secondary pressurization of severing point back and time-delay; rise to the setting-up time rear arm; end-of-job; for different cutting dies; material and material thickness; need to adjust the setting-up time of rocking arm blanking machine; to reach the required pressure of severing and the degree of depth; it is not outstanding to set work problem during single-piece production; but when a large amount of rocking arm blanking machines are produced in batches; it is very heavy that setting work just becomes; in actual production process; it is more frequent changing cutting die or material; consider that the cutting die that present enterprise uses is standardized designs; with the employed cutting die height of the product of a series of or close series is consistent; therefore change the course of work of conventional rocker blanking machine; adopt novel set mechanism, it is feasible simplifying or saving original setting work, also is badly in need of and will solves.

The utility model content

The utility model purpose is the deficiency that overcomes existing rocking arm blanking machine, and a kind of novel cutting die sets mechanism is provided.

The technical solution of the utility model: contain fixed mount, fork, connecting rod, guide post, collision block, handwheel, locking nut, extension spring, slide block, bracing frame, microswitch or sensor etc., fixed mount one end is fixed on the fuselage rear side, the other end extends to rocking arm main shaft top, the end has pin-and-hole to connect fork, the fork other end is fixed with guide post, connecting rod connects fork and rocking arm, slide block slides on guide post, handwheel and slide block thread connection, the end is against on the guide post, collision block and slide block thread connection also have locking nut locking, extension spring is in guide post, and an end is fixed on the guide post top, and the other end is fixed on the bracing frame, bracing frame is fixed on the rocking arm front end, and microswitch or sensor are fixed on the bracing frame.

For bearing pin connects, also can be sliding bearing or rolling bearing and connect between fixed mount and the fork, its axis and rocking arm main shaft are on same straight line.

Two of microswitch or sensor operated by rotary motion, one is secondary pressure position, and one is severing point position, and secondary presses the position if necessary, also can increase the bound position above the position is put in severing.

Operation program is designed to: rocking arm descends fast, pressurizes behind the arrival secondary pressure position and cuts slowly, rises to severing point position rocking arm, finishes a course of work.

The beneficial effects of the utility model are: do not re-use timer and set the severing degree of depth and pressure, but unclamp handwheel easy adjustment severing point position, cutting die for equal height, no matter its severing area size (in the tonnage scope of rocking arm blanking machine), can be general after once setting, greatly facilitate production, improved production efficiency.

Description of drawings

Accompanying drawing 1 is the complete machine structure layout drawing of the utility model embodiment.

Accompanying drawing 2 is the cutaway view of the utility model embodiment.

Among Fig. 1: the 1---fixed mount; The 2---rocking arm; The 3---connecting rod; The 4---fork; The 5---handwheel; The 6---case; The 7---guide post; The 8---bracing frame; The 9---fuselage.

Among Fig. 2: the 5---handwheel; The 7---guide post; The 8---bracing frame; The 10---pin; The 11---extension spring; The 12---slide block; The 13---locking nut; The 14---collision block; The 15---bolt.

The specific embodiment:

Below in conjunction with drawings and Examples the utility model is further specified.

As Fig. 1 and Fig. 2, fixed mount 1 is fixed on the fuselage 9, upper end to rocking arm 2 main shaft places connect fork 4, connecting rod 3 is located fork 4 and rocking arm 2 at horizontal plane, rotate rocking arm 2, fork 4 will rotate around rocking arm 2 main shafts thereupon, guide post 7 one ends are fixed on the fork 4, the other end and bracing frame 8 are slidingly matched, extension spring 11 is arranged in the guide post 7, and the one end is fixed on the pin 10 of guide post 7 upper ends, and the other end is fixed on the bolt 15 in the bracing frame 8, slide block 12 is on guide post 7, the outside is covered with case 6, but unclamps handwheel 5 positions of adjusting slider 12 on guide post 7, collision block 14 and slide block 12 thread connection, rotation collision block 14 can be regulated its position by trace, screws locking nut 13 and can make collision block 14 lockings.

When rocking arm 2 descended or rises, collision block 14 moved up and down with guide post 7, triggered microswitch or sensor and carried out corresponding action, assignment procedure is: cutting die is placed on the workbench of fuselage 9, carry out setting program, rocking arm 2 is slowly descended and touch cutting die, unclamp handwheel 5, sliding slider 12, make collision block 14 touch the microswitch or the sensor of severing point, lock handwheel 5, end setup program; rocking arm 2 will rise, setting work is finished.In the work, if find the severing degree of depth inadequately or dark excessively, also rotatable collision block 14 carries out the trace adjusting, for the cutting die of equal height, setting work only need be carried out once, uses different cutting dies instead, the severing degree of depth can not change, and in the tonnage scope of rocking arm blanking machine, its severing effect is the same.
