Description

Technical Field

[0001] The utility model belongs to the technical field related to electro-hydraulic hammers, and in particular relates to a protective device for an electro-hydraulic hammer. Background Art

[0002] When forging a workpiece, an electro-hydraulic hammer is often used, which uses hydraulic pressure to control the hammer head to strike the workpiece. However, when hammering some metal parts with electro-hydraulic hammers in the prior art, the metal itself will be oxidized, resulting in a layer of oxidized shavings on the surface of many workpieces. When struck, the metal shavings on the surface are shaken out, causing the shavings to splash everywhere, posing a safety hazard to the workers. A protective device for an electro-hydraulic hammer proposed in patent CN202322153620.6, through the cooperation between the protective shell and the first fixed rod, allows the protective shell to move downward along the outer surface of the first fixed rod. At this time, the second clamping block will squeeze the inclined surface of the first clamping block, causing the first clamping block to move outward along the outer surface of the second fixed rod. At this time, because the second spring is in a compressed state, it will exert an elastic force on the first clamping block, so that the cooperation between the first and second clamping blocks can limit the protective shell, and then the protective shell can protect the workpiece and prevent metal shavings from splashing. Although this design meets the needs of use to a certain extent, it is found in actual use that this design is more practical for processing small-sized parts and can enclose the parts in the processing station. However, for some large-sized parts, their size is much larger than the processing station and often requires two operators to perform clamping operations.

[0025] like Figures 1 to 5 As shown, a protective device for an electro-hydraulic hammer comprises a cabinet 1 and a support frame 10. A dead guard plate 6 is fixedly connected to one side of the cabinet 1 through a fixing frame 5. A movable guard plate 7 is provided on one side of the dead guard plate 6. Both the dead guard plate 6 and the movable guard plate 7 are hollow-out designs. A guide column 8 and a screw 12 are embedded in the cabinet 1. One end of the guide column 8 and the screw 12 is provided with a support frame 10. The support frame 10 is U-shaped. An adjustment bracket 18 is connected to one side of the cabinet 1 through a locking bolt 20. The adjustment bracket 18 is provided with an adjustment slot 1 9. The locking bolt 20 is embedded in the adjustment slot 19. One end of the adjustment bracket 18 is integrally formed with a motor frame 21. One side of the motor frame 21 is fixedly connected to the drive motor 24. The fixed guard plate 6 and the movable guard plate 7 serve to block splashes. The guide column 8 serves as a guide. The guide column 8 and the cabinet 1 are fitted with a gap. The adjustment bracket 18 and the motor frame 21 serve as stable supports. The drive motor 24 provides driving force for the device. The drive motor 24 uses a servo motor system and adopts a self-locking design.

[0026] Among them, the bottom of the cabinet body 1 is fixedly connected to the support plate 4, and a reinforcing rib 17 is provided between the cabinet body 1 and the support plate 4. A control box 16 is provided on one side of the cabinet body 1. The control box 16 is fixedly connected to the support plate 4. The support plate 4 plays a role of stable support, and the reinforcing rib 17 plays a role of strengthening support. The control box 16 facilitates automatic control.

[0027] A control panel 2 is embedded in the cabinet 1 and connected to the control box 16 via a wire. A storage box 3 is provided on the cabinet 1 to facilitate human-computer interaction and to facilitate storage of items.

[0028] An adjusting nut seat 13 is provided on the screw 12, and a positioning sensor 11 is embedded in the support frame 10. The positioning sensor 11 adopts a laser sensor design. The positioning sensor 11 is connected to the adjusting nut seat 13 with a control box 16 through a wire to facilitate adjustment of the screw 12. The adjusting nut seat 13 adopts an anti-loosening design, and the positioning sensor 11 plays the role of monitoring the clamping frame.

[0029] A frame body 9 is sleeved on the movable guard plate 7, a magnetic block 15 is embedded in one frame body 9, and an armature 14 is fixedly connected to the other frame body 9. The magnetic block 15 and the armature 14 are designed to correspond to the frame body 9 to play a role in strengthening the support, and the armature 14 and the magnetic block 15 play a role in adsorption and fixed connection.

[0030] Two support seats 22 are fixedly connected to the motor frame 21, and a rotating shaft 25 is set between the support seats 22. Two skeleton bodies 9 are sleeved on the rotating shaft 25. The support seats 22 and the rotating shaft 25 play a role of stable support. The skeleton body 9 and the rotating shaft 25 are connected by bearings.

[0031] A driving gear 23 is sleeved on the skeleton body 9, and a driving gear 26 is sleeved on the output end of the driving motor 24. The driving gear 26 is meshed with the driving gear 23. Both the driving gear 26 and the driving gear 23 are designed with bevel gears, and the driving gear 26 and the driving gear 23 play the role of power transmission.

[0032] The working principle of the present invention is as follows: before use, the device is set at the appropriate positions on both sides of the electro-hydraulic hammer workbench, and the nut seat 13 is rotated and adjusted as needed. After the height of the support frame 10 is adjusted to the appropriate position, the nut seat 13 is locked and adjusted, and the locking bolt 20 is loosened. After the movable guard plate 7 is adjusted to the appropriate height, the locking bolt 20 is tightened. After the relevant circuits are connected through the control box 16, it can be used. When in use, the positioning sensor 11 works. When no signal source is found, the driving motor 24 drives the driving gear 23 to rotate. Because the two driving gears 23 rotate in opposite directions, the two skeleton bodies 9 drive the movable guard plate 7 to expand ninety degrees. When the staff is working, they clamp the workpiece and place the supporting frame on the support frame 10. The positioning sensor 11 detects the signal source, and the driving motor 24 works in reverse, driving the movable guard plate 7 to rotate ninety degrees in the opposite direction. At this time, the movable guard plate 7 is opened. When the guard plate 7 is just closed, the coil in the magnetic block 15 is energized, and the magnetic force generated only attracts the fixed armature 14 to ensure the stability of the movable guard plate 7. At this time, the supporting frame is just in the circular hole formed by the two frame bodies 9, and the workpiece can be flipped during the clamping process. The structural design of the utility model is reasonable and easy to install and use. Through the design of the fixed guard plate 6, the movable guard plate 7 and the drive motor 24, it can not only effectively block the splashing objects to avoid personal injury, but also automatically open and close the movable guard plate 7, reducing the impact on the operator, and having strong practicality and safety. Through the design of the support frame 10 and the adjustment bracket 18, not only the height of the movable guard plate 7 can be adjusted according to needs, and the scope of application is wide, but also the clamping frame can be supported, effectively reducing the labor intensity of the operator, and further improving the practicality and economy of the device.
