Description

Technical Field

[0001] This utility model relates to the field of rolling mill manufacturing technology, and more specifically, to a cold mold static pressure demolding device for large-tonnage casting rolling mill rolls. Background Technology

[0002] Rolls are essential tools in metal rolling, primarily composed of the roll body, roll neck, and shaft end. They are typically rolled using the pressure generated by the rolling of a pair or set of rolls to achieve the desired metal shape. As a core component of the rolling mill, rolls directly affect the quality of the rolled product. Currently, traditional large casting rolls are primarily demolded using an impact method. This involves using a crane to lift a heavy object and impact the roll to be demolded on the ground, thus separating the roll from the mold. This demolding method requires adjusting the impact force of the heavy object for rolls of different sizes and specifications. Excessive impact force can damage the roll and may also be transmitted back to the crane, causing damage. Insufficient impact force will not achieve the desired demolding effect. This method is time-consuming and labor-intensive, and the swing direction and speed of the heavy object are difficult to control. This demolding method is difficult to adjust and not suitable for demolding rolls of different specifications. Furthermore, the impact of the heavy object generates significant noise and poses safety hazards. Utility Model Content

[0026] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] The present invention will now describe a static pressure demolding device for cold molds used in large-tonnage casting rolls, according to an embodiment of the present invention. Please refer to [link to relevant documentation]. Figure 1 As shown, the large-tonnage casting roll cold mold static pressure demolding device of this utility model is used to eject the roll 20 in the mold 10. Example 1

[0028] Please see Figures 1 to 4 As shown, the large-tonnage casting roll cold mold static pressure demolding device includes a first support platform 30, a telescopic pusher device 40, a height adjustment component 50, a limiting baffle 60, and a length compensation roller 70. The first support platform 30 is used to horizontally place the mold 10, that is, the mold 10 is placed horizontally, and its axis extends in the horizontal direction. The first support platform 30 is provided with a mold groove 301 for placing the mold 10. The mold groove 301 is preferably a V-shaped groove with the opening facing upwards, which is suitable for molds 10 of different diameters and can prevent the mold 10 from shaking during demolding. The telescopic pusher device 40 is located on one side of the first support platform 30 and is used to push the roll 20 out of the mold 10 in the horizontal direction. The telescopic pusher device 40 drives the roll 20 to disengage from the mold 10 by outputting linear motion. The telescopic pusher device 40 includes a hydraulic cylinder or a pneumatic cylinder. In this embodiment, as shown... Figure 1 As shown, the telescopic push-die device 40 uses a hydraulic cylinder to apply pressure to one side of the roll 20. The pressure acts on one end of the roll 20, thereby separating the roll 20 from the die 10, avoiding impact from heavy objects, ensuring safety and reliability. Furthermore, the pressure is easily adjustable, and the demolding process uses static pressure, effectively reducing noise during demolding. In this embodiment, as... Figures 1 to 4As shown, the demolding device also includes a base 80, which is spaced apart on the side of the first support platform 30 away from the limiting baffle 60. The cylinder body of the hydraulic cylinder of the telescopic pushing device 40 is mounted on the base 80 to bear the reaction force when the hydraulic cylinder is pushed out. The base 80 is made of multiple steel plates spliced ​​together in a grid structure. The hydraulic cylinder of the telescopic pushing device 40 is fixed on the side of the steel plate facing the first support platform 30. Multiple corner bracing plates 801 are provided on the other side of the steel plate to reinforce the base 80 and ensure the stability of the base 80. The height adjustment component 50 is located below the first support platform 30 and is used to adjust the height of the first support platform 30. The height adjustment component 50 can raise and lower the first support platform 30, thereby changing the placement height of the mold 10. It can accommodate rolls 20 of different diameters and is coaxially arranged with the telescopic rod of the hydraulic cylinder of the telescopic push mold device 40. The large-tonnage casting roll cold mold static pressure demolding device also includes a moving drive component, which is drivenly connected to the height adjustment component 50, so that the height adjustment component 50 can move along the length extension direction of the first support platform 30. The length extension direction of the first support platform 30 is consistent with the length direction of the mold groove 301, and the axial extension direction of the mold 10 is consistent with the length direction of the mold groove 301. In this embodiment, as Figure 4 As shown, the moving drive assembly also includes a telescopic drive component 51, which has a telescopic end. The telescopic end of the telescopic drive component 51 is connected to the height adjustment component 50. The telescopic end of the telescopic drive component 51 drives the height adjustment component 50 to move by making linear motion, thereby adjusting the position of the height adjustment component 50 to ensure the stability of the load on the mold 10. For example, the telescopic drive component 51 includes a hydraulic cylinder, a pneumatic cylinder, or an electric push rod. Figure 5 As shown, in this embodiment, the height adjustment component includes a base 501 and a pad 502. The base 501 has a multi-step structure, and the pad 502 is detachably disposed between the base 501 and the first support platform 30. It can be understood that by setting a multi-step structure, the base 501 forms a stepped structure that rises or falls gradually. The pad 502 is placed on different steps of the base 501 according to the diameter of the mold 10, so that the rollers 20 of different diameters are coaxially arranged with the telescopic rod of the hydraulic cylinder of the telescopic push-die device 40, such as... Figure 5 As shown, the pad 502 can be a cuboid structure. For example... Figure 1 and Figure 4 As shown, the limiting baffle 60 is used to prevent the mold 10 from detaching from the first support platform 30. It is arranged opposite to the telescopic push mold device 40 and is located on the side of the first support platform 30 away from the telescopic push mold device 40. It can be understood that the limiting baffle 60 and the telescopic push mold device 40 are located at opposite ends of the length of the first support platform 30. By cooperating with the height adjustment component 50 and the limiting baffle 60, the weight of the mold 10 and the roll 20, as well as the pressure generated during push molding, can be borne, thus preventing the mold 10 from detaching from the mold groove 301 on the first support platform 30. In this embodiment, as... Figure 4 and Figure 6 As shown, the limiting baffle 60 is provided with a U-shaped opening 601, and one end of the roller 20 passes through the U-shaped opening 601 so that one end of the mold 10 abuts against the limiting baffle 60. Specifically, as Figures 1 to 4 As shown, the two necks of the roll 20 extend from both ends of the mold 10, which is placed in the mold groove 301. The limiting baffle 60 is made of steel plates and has a U-shaped opening 601 for the neck of the roll 20 to pass through. Multiple corner braces 602 are provided on the side of the limiting baffle 60 away from the first support platform 30 to distribute the pressure of the mold 10 on the limiting baffle 60 during demolding. The neck of the roll 20 near the limiting baffle 60 passes through the U-shaped opening 601, and the end of the mold 10 near the limiting baffle 60 abuts against it. When the telescopic rod of the hydraulic cylinder of the telescopic pusher device 40 is extended, pressure is applied to the neck of the roll 20 away from the limiting baffle 60, thereby separating the roll 20 from the mold 10. A length compensation roller 70 is detachably disposed between the first support platform 30 and the telescopic pusher device 40 to transmit pressure to the roll 20 in the horizontal direction. When the length of the roll 20 is insufficient and the telescopic pusher device 40 cannot act on the roll 20, one end of the length compensation roller 70 abuts against the neck of one end of the roll 20, and the other end of the length compensation roller 70 abuts against the telescopic rod of the hydraulic cylinder of the telescopic pusher device 40, thus providing intermediate force transmission. When demolding is required, the telescopic pusher device 40 is activated, and the length compensation roller 70 applies a pushing force to the roll 20. At the same time, the mold 10 is held in place by the limiting baffle 60, thereby pushing the roll 20 out of the mold 10. Preferably, as shown in the figure... Figure 7 and Figure 8 As shown, the length compensating roller 70 has spherical grooves 701 at both ends. By setting the spherical grooves 701, the hydraulic cylinder of the telescopic push-die device 40 can improve the direction of the force when applying force to the length compensating roller 70, so that the center of the length compensating roller 70 coincides with the center of the telescopic rod of the hydraulic cylinder. This utility model, through the coordinated use of the telescopic push-die device 40, the height adjustment component 50, the limiting baffle 60, and the length compensating roller 70, can be applied to the demolding work of large-tonnage casting rolls of different diameters and lengths, thereby realizing the demolding of rolls 20 of different specifications. Example 2

[0029] Please see Figures 1 to 4As shown in the figure, the static pressure demolding device for cold molds of large-tonnage casting rolls provided in this embodiment of the present invention also includes a base plate 90, a telescopic pushing mold device 40, a height adjustment component 50, and a limiting baffle 60 respectively disposed above the base plate 90. The base 80 and the limiting baffle 60 are welded and fixed to the base plate 90. A sliding groove 901 is provided on the base plate 90, and the height adjustment component 50 is slidably connected to the sliding groove 901. Specifically, the height adjustment component 50 is connected within the sliding groove 901 and can move along the sliding groove 901, thereby preventing the movement direction of the height adjustment component 50 from deviating. Preferably, there are multiple sets of height adjustment components 50, and the multiple sets of height adjustment components 50 are spaced apart from each other along the length extension direction of the first bearing platform 30. It can be understood that by setting multiple sets of height adjustment components 50 to support the first bearing platform 30 to support the mold 10, different specifications of rolls 20 can be demolded, achieving the stability of the bearing. Specifically, as Figure 4 As shown, the slide groove 901 is arranged along the length of the first support platform 30, and two bases 501 are arranged alternately within the slide groove 901. The telescopic end of the telescopic drive member 51 is connected to one of the bases 501. The telescopic drive member 51 is a double-acting piston hydraulic cylinder. This arrangement ensures that the base 501 follows the slide groove 901, thus preventing the base 501 from shifting. In this embodiment, as... Figure 4 As shown, a second support platform 100 is provided between the first support platform 30 and the telescopic push mold device 40. The second support platform 100 is provided with a support rod groove 101 for horizontally placing the length compensation rod 70. Preferably, the support rod groove 101 is a V-shaped groove with the opening facing upward. The length compensation rod 70 is coaxially arranged with the telescopic rod of the hydraulic cylinder of the telescopic push mold device 40.

[0030] The working principle of the above scheme is as follows:

[0031] Above the base plate 90, there are sequentially arranged a limiting baffle 60, a first bearing platform 30, a second bearing platform 100, a telescopic push mold device 40, and a base 80. Two sets of height adjustment components 50 are provided between the first bearing platform 30 and the base plate 90. The main body of the hydraulic cylinder in the telescopic push mold device 40 is fixed on the base 80. Before demolding, adjust the distance between the two bases 501 and the height of the two pads 502 in the two sets of height adjustment components 50. Place the mold 10 to be demolded in the mold groove 301. One end of the roller neck of the roll 20 passes through the U-shaped opening 601. The end of the mold 10 near the limiting baffle 60 abuts against the limiting baffle 60. One end of the length compensation roller 70 abuts against the other end of the roller neck of the roll 20. The other end of the length compensation roller 70 abuts against the telescopic rod of the hydraulic cylinder in the telescopic pushing device 40. When demolding, start the telescopic pushing device 40 and apply the pushing force to the roll 20 through the length compensation roller 70. At the same time, the mold 10 is stuck by the limiting baffle 60, so that the roll 20 is pushed out of the mold 10.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
