Description

Technical Field

[0001] The utility model relates to the technical field of roller mold box opening, in particular to a pneumatic hammer box opening device. Background Art

[0002] A roller die is a special mold or tool, usually used in the forming process of metal processing, plastic processing or other materials. In the metal processing industry, the roller die rolling mill is an important equipment, which plastically deforms and processes metal materials through the extrusion force between two or more rollers. During the use of roller dies and end covers, performance degradation or failure may occur due to long-term operation, wear, corrosion or other factors. In order to carry out necessary maintenance and care, such as replacing worn parts, cleaning internal impurities, checking sealing, etc., it is necessary to unpack the roller dies and end covers for detailed inspection and repair of the interior.

[0003] After searching, a Chinese patent with publication number CN219233907U discloses a centrifugal roller ring casting demoulding device. When demoulding, especially the lower end cover, it is necessary to manually use a steel chisel to pry open the centrifugal roller ring and the lower end cover to separate the centrifugal roller ring from the lower end cover, which is time-consuming and labor-intensive and cannot meet the requirements of rapid demoulding and transportation of the centrifugal roller ring blank. Therefore, the high-temperature centrifugal roller ring can be quickly separated from the lower end cover to achieve rapid unpacking and demoulding of the high-temperature centrifugal roller ring blank, avoiding the centrifugal roller ring in a high-temperature state from being exposed to the air for a long time to cool, which affects the product quality of the centrifugal roller ring; at the same time, it solves the problem of time-consuming and labor-intensive use of a steel chisel to pry open the roller ring and the end cover, and effectively improves work efficiency.

[0004] The existing unpacking device usually adopts the method of lifting the mold by a crane and manually unpacking, but this method still has its shortcomings. The operation is complicated, which can easily lead to a slow unpacking speed, low efficiency, and low safety of the unpacking operation. In the unpacking process, the blank is easily broken, which affects the processing progress and increases the processing cost. Utility Model Content

The rollers 13 are embedded in the ground through screws 4, which is conducive to fixing the mounting plate 1 on the ground. The anti-slip strips 2 are conducive to increasing friction and reducing displacement during the use of the mounting plate 1. The mutual cooperation between the adjusting column 6 and the mounting box 5 facilitates the adjustment of the height of the pneumatic hammer 12 to adapt to the height of different molds. The cooperation between the limit block 10 and the square groove 7 facilitates the fixing of the height of the moving adjusting column 6, thereby fixing the position of the pneumatic hammer 12.

[0034] Example 2

[0035] The right end of the mounting plate 1 is rotatably connected with a bidirectional screw rod 16, a motor 17 is fixedly installed on the front side of the right end of the mounting plate 1, a large gear 18 is fixedly connected to the output end of the motor 17, the other end of the bidirectional screw rod 16 is fixedly connected with a small gear 19, the small gear 19 and the large gear 18 are meshed, the front and rear ends of the bidirectional screw rod 16 are both threadedly connected with a moving rod 20, the other end of the moving rod 20 is fixedly connected with a clamping plate 21, the upper and lower ends of the inner part of the clamping plate 21 are rotatably connected with a plurality of rotating plates 22, and the outer part of the rotating plate 22 is provided with an anti- The sliding pad 23 and the clamping plate 21 are fixedly connected with a plurality of conical shells 24 in the middle of the inner side, the conical shell 24 is fixedly connected with a push spring 25 inside, the other end of the push spring 25 is fixedly connected with a push block 26, and the other ends of the two pull rods 9 are fixedly connected with a connecting rod 27. The two-way screw 16 is used to facilitate the movement of the rods 20 to move closer to or farther from each other, and the clamping plate 21 is set to be arc-shaped, which is conducive to fitting the clamped surface of the roller mold 13, and the anti-slip pad 23 is used to increase the anti-slip property and increase the friction, thereby reducing the loosening phenomenon.

[0036] Working principle: When the roller mold 13 needs to be unpacked, first place the mounting plate 1 on a relatively flat area, use the screws 4 on both sides to embed into the ground to fix the mounting plate 1, and then fix the roller mold 13 on the mounting plate 1. When the height of the pneumatic hammer 12 needs to be adjusted according to the position of the roller head 15, pull the connecting rod 27, and the connecting rod 27 drives the pull rods 9 on both sides to be pulled out of the fixed shell 8, so that the limit block 10 is separated from the corresponding square groove 7, squeezed to the fastening spring 11, and then the adjusting column 6 is released from the installation The pneumatic hammer 12 is pulled up to lift the two adjusting columns 6 and slide inside the corresponding mounting box 5, so that the pneumatic hammer 12 can be adjusted according to the height of the roller head 15. After the adjustment, the connecting rod 27 is loosened, and the limit block 10 is pushed into the corresponding square groove 7 by the rebound of the fastening spring 11. This makes it easier to fix the position of the adjusting column 6 and the pneumatic hammer 12, and then the pneumatic hammer 12 is turned on, and the roller head 15 is adjusted by the pneumatic hammer 12. The roller mold 13 is then turned around and the pneumatic hammer 12 is used to knock the end cover 14 off, which is convenient for demoulding. When the position of the roller mold 13 needs to be fixed, the motor 17 is started, and the output end of the motor 17 drives the large gear 18 to rotate. Due to the meshing of the large gear 18 and the small gear 19, it is convenient for the large gear 18 to rotate and drive the small gear 19 to rotate, so that the small gear 19 drives the two-way screw rod 16 to rotate, which is convenient for the small gear 19 to drive the two-way screw rod 16 to rotate. When the bidirectional screw rod 16 rotates, it drives the moving rods 20 on both sides to approach each other, so that the moving rods 20 drive the corresponding clamping plates 21 to approach each other to clamp the roller mold 13. During the clamping process, the rotating plate 22 contacts the clamped surface, causing the rotating plate 22 to rotate and press against the clamped surface. Then, with the assistance of the anti-slip pad 23, it is convenient to improve the tightness during clamping. During the clamping process, the pushing block 26 contacts the clamped surface, causing the pushing block 26 to be pushed by the pushing spring 25, which is beneficial to enhance the tightness of the clamping.

[0037] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
