Description

Punch press automatic material connection manipulator

Technical field

The utility model relates to a kind of manipulator, relates in particular to a kind of punch press automatic material connection manipulator.

Background technology

Gantry punch press is the larger equipment of a kind of build, and the motor production unit is commonly used it and come punching stator or rotor steel disc.Generally need two workmans to operate, a workman carries out the material loading operation, another workman operation that connects material, the operation of punch press is to be controlled by the material loading workman with stopping, therefore the material loading workman comparatively initiatively, the operator that connects material is in more passive position, therefore needs the work of two people's close fit, otherwise the workman that connects material easily rushes hand, causes security incident.

The utility model content

The utility model purpose: the purpose of this utility model provides a kind of punching machine mechanical arm that can automatic material connection.

Technical scheme: a kind of punch press automatic material connection manipulator described in the utility model, comprise lathe bed and place the interior drift of lathe bed, upper trimming die and lower punch die are set below drift, lathe bed in punch die one side is established turning cylinder, be mounted with at the electromagnetism receiver between the punch die up and down at this turning cylinder, and establish return spring at turning cylinder, simultaneously at this turning cylinder projection is set, at drift the push rod that is used in conjunction with projection is set, push rod, projection, turning cylinder and electromagnetism receiver form link gear in the process that drift moves up and down; The discharging electromagnet that can adsorb workpiece on the electromagnetism receiver is installed at lathe bed; On lathe bed, a side adjacent with drift establish up and down two switches; When drift is moving up and down when touching switch in the process, upper switch connection, lower switch disconnects, and this moment, the electromagnetism receiver was in "on" position; When drift touched lower switch, lower switch connection was gone up switch simultaneously and is disconnected, and discharging this moment electromagnet is in "on" position.

Wherein, described lathe bed is provided with discharging electromagnet gripper shoe.The two ends of described turning cylinder connect respectively top chock and step.

Operation principle: plugged, punch press is started working, at first drift moves down the punching workpiece, when drift touches upper switch, upper switch connection, lower switch disconnects, electromagnetism receiver energising this moment and absorption workpiece, along with moving down of drift, the push rod on the drift is stirred projection, is made projection rotate moving axis to inner rotary, the electromagnetism receiver under the drive of turning cylinder from up and down between the punch die to inner rotary to the discharging electromagnet; When drift touches lower switch, lower switch connection, upper switch disconnects, electromagnetism receiver outage this moment, the discharging electromagnet gets electric and the absorption workpiece, and drift moves up simultaneously, and electromagnetic disc is being returned under the effect of return spring up and down between the punch die; When drift touches upper switch, repeat said process.

Beneficial effect: the utility model compared with prior art, its remarkable advantage for this manipulator by electromagnetism receiver, discharging electromagnet and being used in conjunction with of switch up and down, realize that automatic material connection replaces manually connecting material, not only the saving of labor, save time, efficient, easy to operate, can avoid simultaneously the generation of security incident.

The specific embodiment

Shown in Fig. 1-5, the utility model comprises lathe bed 1 and places the interior drift 2 of lathe bed, upper trimming die 3 and lower punch die 4 are set below drift 2, lathe bed in punch die one side is established turning cylinder 5, the two ends of turning cylinder 5 connect respectively top chock 11 and step 12, and the metal (upper seat is installed on the lathe bed 1.Be mounted with at the electromagnetism receiver 6 between the punch die up and down at this turning cylinder 5, and establish return spring at turning cylinder 5, simultaneously at this turning cylinder projection 6 is set, arrange and protruding 6 push rods that are used in conjunction with 8 at drift 2, push rod 8, projection 6, turning cylinder 5 and electromagnetism receiver 7 form link gear in the process that drift 2 moves up and down.At lathe bed 1 discharging electromagnet gripper shoe 10 is installed, in gripper shoe 10 the fixing discharging electromagnet 9 that can adsorb workpiece on the electromagnetism receiver 7 is installed; On lathe bed 1, a side adjacent with drift 2 establish up and down two switches; When drift 2 is moving up and down when touching switch 13 in the process, upper switch 13 is connected, and lower switch 14 disconnects, and this moment, the electromagnetism receiver 7 was in "on" position; When drift 2 touched lower switch 14, lower switch 14 was connected, and went up switch 13 simultaneously and disconnected, and discharging this moment electromagnet 9 is in "on" position.

Shown in Fig. 6-7, the 220V AC power is depressurized to 12V～and 6.3V～low-voltage alternating current power supply through transformer T, and wherein, 6.3V～low-voltage alternating current power supply is for indicator lamp; 12V～low-voltage alternating current power supply produces strong magnetic attraction for electromagnetism receiver 7 and discharging electromagnet 9 after bridge full-wave rectifier and filtering.Close behind the miniature circuit breaker QF, indicator lamp is bright, and indication circuit begins normal operation.When the drift 2 of punch press upwards moves, when touching upper switch 13, namely touches power switch Q1, the normally open contact of power switch Q1 (moving together contact) closure, normally closed interlock disconnects simultaneously, makes A.C. contactor KM1 energising, A.C. contactor KM2 outage.After the A.C. contactor KM1 energising work, electromagnetism receiver 7 produces magnetic attractions, the steel disc that punching is good firmly hold and with turning cylinder 5 to inner rotary.When drift 2 operation downwards, although power switch Q1 has recovered nature, often open, normally closed interlock is connected and the conversion of closure, because the auto-lock function of A.C. contactor C1, electromagnetism receiver 7 has electricity eventually at whole feeding running, has guaranteed that steel disc can not fall down at running.Until switch 14 under drift 2 strikings, namely touch power switch Q2, this moment A.C. contactor KM1 dead electricity, electromagnetism receiver 7 is dead electricity thereupon also, magnetic attraction is eliminated, A.C. contactor KM2 energising work this moment, and discharging electromagnet 9 is subjected to electricity work to produce magnetic attraction, the steel disc of electromagnetism receiver 7 is picked up, and electromagnetism receiver 7 returns up and down between the punch die simultaneously.Until in drift 2 strikings behind the switch 13, discharging electromagnet 9 just quits work, steel disc falls in the steel disc storing unit that pre-sets.Finish the automatic material connection, discharging of what a bout, the overall process of putting.
