Abstract

The utility model discloses a semi-automatic stepwise riveting machine, which comprises a machine body and a stamping die, wherein a rotating disc and a device for driving the rotating disc to stepwise rotate are arranged above the machine body and below the stamping die; a great number of stamping die holes are processed at the circumference edge of the rotating disc; the stepwise rotation device is a ratchet mechanism; a ratchet is fixedly socketed on the main shaft of the rotating disc; pallets are arranged beside the circumference of the ratchet; and a mechanism for driving the pallets to move is arranged on the machine body. By adopting the semi-automatic stepwise riveting machine, feeding and discharging operations are not required to be performed by the operating personnel below the die; and the material is fed to the stamping die holes from one end of the rotating disc, the rotating disc is rotated, the workpiece to be riveted is conveyed to lower side of the stamping die for stamping and riveting, after riveting, the rotating disc continues rotating to convey the finished product to the control region of the operating personnel so as to discharge the finished product, thus the hands of the operating personnel are not required to be placed below the stamping die during the whole production process, the safe production is guaranteed and the accident is completely avoided.

Description

Semi-automatic step-by-step movement lock seaming machine

Technical field:

The utility model belongs to field of machine tool equipment, refers in particular to a kind of semi-automatic step-by-step movement lock seaming machine.

Background technology:

General lock seaming machine commonly used is that motor drags flywheel through switch, bent axle, connecting rod promotion slide block, carries out work by the mould that is fixed on the slide block below.Traditional lock seaming machine is all by formpiston and former cooperating; Formpiston is located at the top; Formpiston is located on the working face; The course of work all requires operating personnel directly below mould, to carry out operation of feeding and discharging with hand, and lock seaming machine does not all dispose safety guard, and operating personnel are in case carelessness just can cause industrial accident.This also is the insoluble for a long time difficult problem of factory and enterprise.

Summary of the invention:

The purpose of the utility model is in order to overcome the shortcoming of above-mentioned prior art, to provide a kind of safe and reliable, can avoid the semi-automatic step-by-step movement lock seaming machine of accident generation fully, can improving operating personnel's operating efficiency.

For realizing above-mentioned purpose; The technical scheme that the utility model provides is: semi-automatic step-by-step movement lock seaming machine; Include body and diel; Below diel on the body, be provided with rolling disc, also be provided with and drive the device that rolling disc is done the stepping rotation, on the circumferential edge of rolling disc, be processed with a large amount of punching press nibs.

Described stepping tumbler is a ratchet mechanism, and ratchet is fixedly sleeved on the main shaft of rolling disc, is provided with ratchet on ratchet circumference next door, and body is provided with the mechanism that drives the ratchet motion.

The mechanism that drives the ratchet motion is made up of swing arm, gangbar group and dwang, and the swing arm movable axis is connected on the rolling disc main shaft, and ratchet is installed on the swing arm; Dwang is socketed on the body; One end of gangbar group is connected with swing arm, and the other end is connected with dwang, is extended with first drive link on the dwang; On the flywheel wheel card of lock seaming machine, be connected with to second drive link that extends below with eccentric ways of connecting, first dwang is connected with second drive link.

After said structure improves, utilize the effect of rolling disc, can make operating personnel directly below mould, carry out operation of feeding and discharging; As long as operating personnel are at the past punching press nib material loading of an end of rolling disc; Turn disc is delivered to diel below with the workpiece of treating riveted and is carried out punch riveting, and rolling disc is rotated further the operating area place that finished product is delivered to operating personnel and carries out blanking behind the riveted; Thereby make whole process of production; Operating personnel's hand need not place the below of diel, guarantees safety in production, has avoided the generation of accident fully.

Description of drawings:

Fig. 1 is the last TV structure figure of the semi-automatic step-by-step movement lock seaming machine of the utility model;

Fig. 2 is the structure chart of facing at the semi-automatic step-by-step movement lock seaming machine of the utility model flywheel place.

The specific embodiment:

Combine accompanying drawing to set forth the utility model in detail at present:

As attaching illustrated in figures 1 and 2ly, the semi-automatic step-by-step movement lock seaming machine of present embodiment includes body 1 and diel 2, below body 1 the place ahead, diel 2, is provided with rolling disc 3; On the circumferential edge of rolling disc 3, be processed with a large amount of punching press nibs 4, the center of all punching press nibs is on the same circumference, and the top of rolling disc 3 is provided with activity technology steady pin 14 and alignment pin governor motion 15; The effect of activity technology steady pin 14 is to make accurately location, the moving once back of rolling disc 3 revolutions; Fixed cover is connected to ratchet 5 on the main shaft of rolling disc 3, makes rolling disc 3 and ratchet 5 realize rotating synchronously, is provided with ratchet 6 on ratchet 5 circumference next door; Movable sleeve is connected to swing arm 7 on the main shaft of rolling disc 3; Ratchet 6 is installed on the swing arm 7, also is connected with back-moving spring 8 between ratchet 6 and the swing arm 7, and back-moving spring 8 is in tension; Guarantee that ratchet 6 cooperates with ratchet 5 all the time; Be provided with dwang 9 at the rear of body 1, be connected with gangbar group 10 between swing arm 7 and the dwang 9, be extended with first drive link 11 on the dwang 9; Take turns on the card to be connected with to second drive link, 13, the first dwangs 11 that extend below at the flywheel 12 of lock seaming machine and be connected with second drive link 13 with eccentric ways of connecting.

Operation principle: the flywheel 12 of lock seaming machine rotates, and except drive diel 2 moves up and down, also drives second drive link 13 and moves up and down; The power that moves up and down of second drive link 13 changes the torsion that comes back rotation into through first drive link 11; This torsion drives dwang 9 and comes back rotation, and the rotation of dwang 9 drives gangbar group 10 and moves around, thereby orders about the action that swing arm 7 works swing back and forth; Ratchet 6 on the swing arm 7 is under the acting in conjunction of the swing back and forth action and the back-moving spring 8 of swing arm 7; Every swing once, all can driving pawl 5 and rolling disc 3 change and move a step, finally make rolling disc 3 realize that steppings rotate; Material loading and blanking need not carried out in the punch riveting district, realize avoiding fully the generation of accident.

The above only is the preferred embodiment of the utility model, is not the utility model is done any pro forma restriction.Any those of ordinary skill in the art; Do not breaking away under the utility model technical scheme scope situation; All the method for above-mentioned announcement capable of using and technology contents are made many possible changes and modification to the utility model technical scheme, or are revised as the equivalent embodiment of equivalent variations.So every content that does not break away from the utility model technical scheme, the equivalence of doing according to shape, structure and the principle of the utility model changes, and all should be covered by in the protection domain of the utility model.
