Referring to fig. 5 and 6, a second embodiment of the present application provides another programmable free-forging electro-hydraulic hammer based on the programmable free-forging electro-hydraulic hammer provided in the first embodiment of the present application. The second embodiment is only the preferred mode of the first embodiment, and the implementation of the second embodiment does not affect the implementation of the first embodiment alone.

Specifically, the difference of programme-controlled free forging electrohydraulic hammer that the second embodiment of this application provided lies in, programme-controlled free forging electrohydraulic hammer, the bottom of hammer body 1 is provided with protection component 7, protection component 7 includes protection casing 71, fixedly connected with observation window 72 on the protection casing 71 to fixedly connected with backup pad 73 on the protection casing 71, fixedly connected with slide bar 74 on the backup pad 73, reset spring 75 has been cup jointed on the surface of slide bar 74 to sliding connection has driving plate 76 on the slide bar 74, the lift groove 77 has been seted up on the protection casing 71, the inside sliding connection of lift groove 77 has guard flap 78, fixed mounting has trigger plate 79 on the tup 2.

Both sides of the protective cover 71 can be provided with a rotary type opening and closing state, so that the protective cover 71 can be opened from both sides, and a workpiece during machining can be conveniently turned over or moved.

Protection casing 71 fixed mounting be in the bottom of tup 2, lift groove 77 is provided with two altogether, two lift groove 77 symmetric distribution is in the both sides of observation window 72, reset spring 75 is located the bottom of driving plate 76, backup pad 73 is located the outside of protection casing 71, driving plate 76 with the surface sliding connection of protection casing 71.

The lifting groove 77 limits the protective baffle 78, so that the protective baffle 78 can only move up and down, the reset spring 75 supports the transmission plate 76, the transmission plate 76 is driven to move when the protective baffle 78 moves down, the reset spring 75 contracts, and when the protective baffle 78 is not pushed any more, the reset spring 75 can push the protective baffle 78 to reset.

The one end of driving plate 76 with guard flap 78's fixed surface is connected, trigger plate 79 is located directly over guard flap 78, the structure of observation window 72 both sides is the same, one side fixed mounting of observation window 72 has safety guard 8, safety guard 8 adopts transparent material, the curb plate and the protection casing 71 main part of protection casing 71 fixed support plate 73 one side are rotated and are connected to be provided with the setting element that is used for the rotatory back of curb plate on the curb plate.

The curb plate is rotatable, can add man-hour or the work piece processing back of accomplishing at the work piece, and rotatory curb plate takes out the work piece, and protection casing 71 cooperation blast wall can reach sealed effect to protection casing 71 for reduce the volume that the inside dust of protection casing 71 flowed out, make the environmental quality that can effectual promotion production environment.

The upper portion of protection casing 71 is provided with sealed shell 9, fixedly connected with a plurality of blowing pipes 10 on the sealed shell 9, it is a plurality of blowing pipe 10 evenly distributed is in on the sealed shell 9, fixedly mounted has the air exhauster that is used for providing the wind to sealed shell 9 on the protection casing 71.

The control switch controls the operation of the exhaust fan, so that the exhaust fan box sealing shell 9 provides air, the air is exhausted from one end of the blowing pipe 10, and the exhausted air forms an air wall at the top of the protection cover 71, thereby reducing the amount of dust flowing out from the interior of the protection cover 71 when the hammer 2 processes a workpiece.
