Abstract
The invention discloses a safety protection device of a rigid punching machine. The punching machine comprises a manipulator and a pedal switch, wherein the pedal switch is connected with the manipulator by a connecting rod, the safety protection device comprises a safety door which is provided with a drive part, while the manipulator is provided with an ejector pin which is connected with the connecting rod, an oscillating bar which can oscillate leftwards and rightwards is arranged below the ejector pin, the drive part is located at one end of the oscillating bar and drives the oscillating bar to rotate when the safety door is closed.Compared with the prior art, as the punching machine of the invention is provided with a safety protection device, no body part of the operator can enter the mould punching area in punch progression and meanwhile when the safety is not closed, the oscillating bar prevents the ejector pin from going downward, so that the operator can not step down the pedal switch in case of misoperation, thus effectively protecting the operation from danger.
Description
Technical field
The relevant a kind of punching apparatus of the present invention relates to a kind of safety protection device of rigid punching machine specifically.
Background technology
Rigid punching machine security protection in the market is poor; particularly adopt pedal not possess security basically, and the protected mode of existing punch press mainly adopt the mode of photoelectric protector and both hands button to carry out safeguard protection as the operating mechanism rigid punching machine.Because these devices all adopt electic protection, its security reliability has certain limitation, particularly to not being suitable for the rigid punching machine of foot-driven lever as operating mechanism.
Summary of the invention
The objective of the invention is at the problems referred to above, provide a kind of simple in structure, can be to the foot-driven lever being the safety protection device of rigid punching machine that the rigid punching machine of operating mechanism carries out the effective and safe protection.
For achieving the above object, the present invention adopts following technical scheme:
A kind of safety protection device of rigid punching machine; this rigid punching machine comprises an executor and a pedal; this pedal connects this executor by a connecting rod; this protective device comprises a safety door; this safety door is provided with actuator; and described punch press executor is provided with a push rod that is connected with described connecting rod, and a fork that can swing is installed below this push rod, and described actuator is positioned at an end of this fork and turns this fork when described safety door is closed.
Described actuator is one to be fixed in the fixed head of described safety door, is provided with slanting baffle in the lower end of this fixed head.
Bearing is equipped with in corresponding end at described fork, makes that the resistance of described slanting baffle driving fork is littler.
This protective device also comprises safety door locking device; this locking device is one to be installed on the curved bar of punch press; the keyed end of this curved bar clip when described safety door is closed and is removed locking to described fixed head at described fixed head top when punch press finishes punching stroke.
On the punch press flywheel clutch, be provided with job key, the end of the described curved bar of butt when this job key finishes punching stroke at punch press.
On described safety door, be provided with extension spring.
Compared with prior art; because rigid punching machine of the present invention is provided with safety guard; make the operator in punching course; the any position of health can't enter the mould Stamping Area; simultaneously when not having drop-down closure at safety door; stop push rod descending by fork, make the operator when maloperation, can't step on pedal, thereby can effectively protect operator's safety.
Description of drawings
Fig. 1 be safety guard of the present invention on rigid punching machine whole front schematic view.
Fig. 2 is the whole side schematic view of Fig. 1.
Among the figure
The 1-safety door, the 2-guide pillar, the 3-curved bar, the 4-clutch, the 5-job key, the 6-executor,
7-executor cam, the 8-push rod, the 9-fork, the 10-bearing, the 11-fixed head,
The 12-slanting baffle, 13-pedal, 14-connecting rod, 15-slide block, 16-back-moving spring
The specific embodiment
The invention will be further described below in conjunction with the drawings and specific embodiments.
As depicted in figs. 1 and 2; rigid punching machine of the present invention; comprise an executor 6 and a pedal 13; this pedal 13 connects this executor 6 by a connecting rod 14; the protective device of this rigid punching machine comprises a safety door 1, and this safety door 1 is provided with actuator, and described executor 6 is provided with a push rod 8 that is connected with described connecting rod 14; be provided with a fork that can swing 9 below this push rod 8, described actuator is positioned at an end of this fork 9 and turns this fork 9 when described safety door 1 is closed.
Described actuator is one to be fixed in the fixed head 11 of described safety door 1, is provided with slanting baffle 12 in the lower end of this fixed head 11.And bearing 10 is housed in the corresponding end of described fork 9, it is littler to make slanting baffle 12 turn the resistance of fork 9.
This protective device also comprises safety door locking device; this locking device is one to be installed on the curved bar 3 of punch press; the keyed end of this curved bar 3 clip when described safety door 1 is closed and is removed locking to described fixed head 11 at described fixed head 11 tops when punch press finishes punching stroke.
On punch press flywheel clutch 4, be provided with job key 5, the end of the described curved bar 3 of butt when this job key 5 finishes punching stroke at punch press, thus turn the locking that curved bar 3 is removed fixed head 11.On described safety door 1, be provided with extension spring 16, be used for safety door 1 automatically reseting after unlocking.
Its course of work is as follows: the operator puts into safety door 1 under the mould post-tensioning to workpiece, safety door 1 descends along guide pillar 2, fixed head slanting baffle 12 promotion forks 9 end bearings 10 that are installed on the safety door 1 make its other end leave push rod 8 belows, safety door fixed head 11 tops are blocked in curved bar 3 ends simultaneously, and safety door 1 can't upwards be slided.Operating personnel step on pedal 13, executor cam 7 leaves clutch job key 5, clutch 4 is connected, slider of punch 15 moves down stamped workpieces, clutch job key 5 promotes curved bar 3 ends when rotated simultaneously, the keyed end of curved bar 3 leaves fixed head 11, safety door 1 is risen under the pulling force of extension spring 16 automatically reset.When safety door 1 is not left behind fork 9 be stuck in push rod 8 below, when pedal 13 was stepped in operating personnel error, push rod 8 can't descend, punch press can't be worked, and can reach the safeguard protection purpose like this.
Above the present invention is described in detail, has used specific case herein principle of the present invention and embodiment are set forth, the explanation of above embodiment just is used for helping to understand method of the present invention and core concept thereof; Simultaneously, for one of ordinary skill in the art, according to thought of the present invention, the part that all can change in specific embodiments and applications, in sum, this description should not be construed as limitation of the present invention.
