Description

Technical Field

[0001] The invention relates to a three-axis linkage skateboard brick pressing system and a pressing process thereof, belonging to the technical field of skateboard brick production. Background Art

[0002] As the refractory market becomes increasingly severe, there is a shortage of non-renewable raw materials worldwide, and high-quality, high-performance raw materials are in short supply and expensive. The whole skateboard brick uses uniform high-grade raw materials, and the cost pressure is getting greater and greater, making it difficult to maintain the good benefits and sustainable development of the enterprise.

[0003] At the same time, as a functional refractory material for steelmaking, skateboard bricks have relatively harsh use conditions. Therefore, the service life and safety of skateboard bricks are important evaluation indicators. The molding process is a key process in the production and manufacturing of skateboard bricks. The density and uniformity of each part of the skateboard bricks during the molding process have an important impact on the performance and use effect of the skateboard bricks. In traditional brick pressing molds, especially when producing skateboard bricks with lower bosses (this type of skateboard brick is mainly used in sliding nozzles with a sub-mouth matching method), it is necessary to pile more materials on the lower boss part, but currently it is only based on manual control, and most of them are manual pressing and stacking operations. First, the stacking requires manual control and is difficult to obtain precise control. Second, the stacking of materials on the lower boss part is added in batches, and the stress conditions of the added materials are different, which will cause the problem of inconsistent density.

[0053] According to the above description, the composite skateboard brick pressing mold includes a floating upper mold 1, a mold box 2, a lifting mechanism 3 and a floating lower mold 4; an upper mold plate 11 and an upper mold cover 12 are arranged on the floating upper mold 1, and the upper mold cover 12 is mainly used to provide pressure from the top to press the skateboard brick body 7; the mold box 2 includes a floating mold frame 21, a support plate 22, a core rod 23 and a support rod 24, the floating mold frame 21 limits the outer periphery of the skateboard brick body 7, and the core rod 23 is used to limit the inner diameter of the flow steel hole neck tube 74 of the skateboard brick body 7; a top mold ... support seat 32, and the top mold 11 and the upper mold cover 12 are mainly used to provide pressure from the top to press the skateboard brick body 7; the top mold 11 and the upper mold cover 12 are mainly used to provide pressure from the top to press the skateboard brick body 7; the top mold 11 and the upper mold cover 12 are mainly used to provide pressure from the top to press the skateboard brick body 7; the top mold 11 and the upper mold cover 12 are mainly used to provide pressure from the top to press the skateboard brick body 7; the top mold 11 and the upper mold cover 12 are mainly used to provide pressure from the top to press the skateboard brick body Tube 31, a horizontally penetrating slide groove is opened in the middle of the top tube 31, and the support plate 22 of the mold box 2 is slidably sleeved in the slide groove, so that the mold box 2 can move up and down; the floating lower mold 4 includes a lower mold plate 41, a lower mold seat 42 and a lower mold core 43, and the lower mold core 43 is mainly used to provide pressure at the bottom to press the slide brick body 7. At the same time, the upper end of the lower mold core 43 is located at the outer periphery of the top tube 31 and is provided with a guide cone 44 (that is, corresponding to the interface cone 77 of the slide brick body 7); the driving mechanism and provide power to drive the floating lower mold 4 to move up and down.

[0054] Furthermore, it also includes a ring 25; the ring 25 includes an inner sleeve and an outer sleeve coaxially spaced and at the same height; the inner sleeve and the outer sleeve are fixed by a plurality of evenly spaced horizontal connecting rods; the lower end of the ring 25 abuts against the upper end of the top pipe 31, and its upper end is flush with the upper end of the core rod 23; the inner sleeve is movably sleeved on the outer periphery of the core rod 23, and the outer diameter of the outer sleeve is smaller than the inner diameter of the top pipe 31.

[0055] According to the above description, as an important part of the process of the present invention, the sleeve 25 includes an inner sleeve and an outer sleeve. When distributing the materials, a high-temperature material 81 is filled between the inner sleeve and the outer sleeve of the sleeve 25, and a common peripheral material 82 is filled outside the outer sleeve of the sleeve 25. Then, the sleeve 25 is taken out before the pre-pressing process. After the pre-pressing process, the high-temperature resistant material is used at the flow steel hole neck tube 74 of the slide brick body 7, and only the common peripheral material 82 is used at other positions, so as to meet the cost requirements. At the same time, due to the compensation section L reserved before the pre-pressing, after the entire pressing process of the slide brick body 7 is completed, the common brick body 72 composed of the common peripheral material 82 and the flow steel hole neck tube 74 composed of the high-temperature resistant material can reach their respective pre-set compression ratios.

[0056] In particular, if the outer diameter of the outer jacket is smaller than the inner diameter of the top tube 31 , part of the common peripheral material 82 will fall on the outer periphery of the outer jacket on the compensation section L during the second distribution.

[0057] Furthermore, the lower end of the upper mold cover 12, the inner periphery of the floating mold frame 21, the upper end of the lower mold core 43, the inner side of the guide cone 44, the upper end of the top tube 31 and the outer periphery of the core rod 23 are surrounded to form a cavity for pressing the slide brick body 7; the slide brick body 7 includes a high-temperature resistant brick body 71 made of high-temperature resistant material and an ordinary brick body 72 made of ordinary peripheral material 82; the high-temperature resistant brick body 71 includes a horizontal working plate 73 and a fixed on the working plate 7 3; the ordinary brick body 72 includes a horizontal bottom plate 75 and an interface cone 77 vertically fixed to the lower end of the bottom plate 75 and gradually shrinking downward; the outer periphery of the interface cone 77 is fitted to the inner periphery of the guide cone 44; a vertical hollow center hole 76 is opened in the middle of the ordinary brick body 72; the center hole 76 is fixed to the outer periphery of the flow steel hole neck tube 74; the lower end of the flow steel hole neck tube 74 is flush with the lower end of the interface cone 77.

[0058] According to the above description, the pressed skateboard brick body 7 includes a high temperature resistant brick body 71 made of high temperature resistant material and a common brick body 72 made of common peripheral material 82. In particular, since only the upper surface and the inner ring of the brick blank will contact the high temperature molten iron during use, the rest of the brick does not need to be resistant to high temperature. Therefore, in order to save costs, only the part contacting the molten iron can be made of high temperature resistant material, and the rest of the part can be made of common peripheral material 82.

[0059] Furthermore, it also includes a pre-pressing mechanism 5; a contoured upper mold core 51 is disposed at the lower end of the pre-pressing mechanism 5; the contoured upper mold core 51 is disposed horizontally; the outer periphery of the contoured upper mold core 51 is movably sleeved on the inner periphery of the floating mold frame 21, and the inner periphery is movably sleeved on the outer periphery of the core rod 23. The pre-pressing mechanism 5 and the contoured upper mold core 51 are mainly used to pre-press the ordinary peripheral material 82 and the primary high-temperature material 81 at the flow steel hole neck tube 74 after the second material distribution (i.e., the ordinary peripheral material 82) is completed, so that the two have almost the same compression ratio.

[0060] Furthermore, the upper end of the core rod 23 is flush with the upper end of the floating mold frame 21. The upper end of the core rod 23 is flush with the upper end of the floating mold frame 21, mainly to ensure that during the material laying process, the ordinary peripheral material 82 and the primary high-temperature material 81 are both outside the core rod 23, ensuring that the hole in the middle of the skateboard brick body 7 is reserved.

[0061] Furthermore, the upper end of the core rod 23 penetrates into the lower end surface of the upper mold cover 12, mainly to further ensure that a hole position in the middle of the skateboard brick body 7 is reserved.

[0062] Furthermore, the driving mechanism is an oil cylinder 6 ; the oil cylinder 6 is vertically arranged on the ground, and a piston rod at the upper end thereof is fixed to the lower end of the lower template 41 .

[0063] A pressing process of a three-axis linkage skateboard brick pressing system, the specific steps are as follows:

[0064] Step 1: Preparation stage:

[0065] The driving mechanism drives the floating lower mold 4 to move upward, and reserves a compensation section L between the upper end surface of the top tube 31 and the lower end surface of the guide cone 44; then, the floating mold frame 21 is lifted up, and the height required for laying the ordinary peripheral material 82 is reserved between the upper end surface of the floating mold frame 21 and the upper end surface of the lower mold core 43, ensuring space for the first and second laying; finally, the inner sleeve of the ring 25 is set on the outside of the core rod 23, the lower end of the ring 25 abuts against the upper end of the top tube 31, and the ring 25 is kept flush with the upper end of the core rod 23.

[0066] In order to save costs, two materials are used, resulting in different materials of high temperature resistant material and ordinary peripheral material 82, so the compression ratio of the two is also different. If the lower end surface of the primary high temperature material 81 is directly flush with the lower end surface of the ordinary peripheral material 82 during the material distribution, then after pressing, either the lower end surface of the primary high temperature material 81 is flush with the lower end surface of the ordinary peripheral material 82, but the flow steel hole neck tube 74 will not reach the predetermined density and cannot meet the use requirements; or the flow steel hole neck tube 74 reaches the specified density, but due to the "shrinkage" during the pressing process, the lower end of the flow steel hole neck tube 74 is short of material, which also cannot meet the use requirements. For this reason, in order to keep the lower end surface of the primary high temperature material 81 flush with the lower end surface of the ordinary peripheral material 82 after the final pressing work, it is necessary to set a compensation section L for the "shrinkage" of the primary high temperature material 81 before the first and second distribution, so as to prevent the density from not meeting the standard or the lack of material after pressing.

[0067] In particular, the sum of the compensation section L and the compression stroke of the common peripheral material 82 (i.e., the total compression stroke of the steel hole neck tube 74 in the corresponding primary high-temperature material 81) should be able to meet the compression ratio requirement of the steel hole neck tube 74. In actual production, the compensation section L can be preliminarily calculated based on the compression ratio and compression stroke of the common peripheral material 82 and the primary high-temperature material 81 at the steel hole neck tube 74; then, after several trial molds and fine adjustments, the appropriate compensation section L is finally determined.

[0068] Step 2: First fabric cutting:

[0069] The primary high-temperature material 81 is evenly filled between the inner sleeve and the outer sleeve of the collar 25 through the material cart, and the height of the primary high-temperature material 81 is kept flush with the upper end of the collar 25, completing the first distribution.

[0070] Step 3: Second fabric:

[0071] The common peripheral material 82 is evenly filled between the outer periphery of the sleeve 25 and the inner periphery of the floating mold frame 21 by a material cart, and the height of the common peripheral material 82 is kept flush with the upper end of the floating mold frame 21 to complete the second feeding; finally, the sleeve 25 is taken out.

[0072] Step 4: pre-pressing;

[0073] The pre-pressing mechanism 5 is driven to move the contoured upper mold core 51 to above the common peripheral material 82, and then the pre-pressing mechanism 5 is driven downward to drive the contoured upper mold core 51 downward, thereby pre-pressing the common peripheral material 82 and the primary high-temperature material 81 at the same time, thus completing the pre-pressing work; finally, the pre-pressing mechanism 5 is driven to reset.

[0074] Step 5: The third fabric;

[0075] The floating mold frame 21 is lifted up again to leave the required height for the secondary high-temperature material 83 to be laid; then, the secondary high-temperature material 83 is evenly filled into the space formed by the outer periphery of the core rod 23 and the inner periphery of the floating mold frame 21 through the material cart, and the height of the secondary high-temperature material 83 is kept flush with the upper end of the floating mold frame 21, completing the third laying.

[0076] Step 6: Pressing of skateboard bricks;

[0077] The floating upper mold 1 is driven to move the upper mold cover 12 to above the secondary high-temperature material 83, and then the floating upper mold 1 is driven downward, and the upper mold cover 12 presses down the secondary high-temperature material 83; then, the floating lower mold 4 gradually descends under the pressure of the floating upper mold 1 until the floating lower mold 4 is pressed on the support seat 32, and the compensation section L is eliminated; finally, the floating upper mold 1 is applied to the maximum pressure until the skateboard brick body 7 is pressed into shape.

[0078] Step 7: demoulding;

[0079] The floating upper mold 1 is driven to move upward and reset; then, the floating mold frame 21 is moved downward or the driving mechanism drives the floating lower mold 4 to move upward, and the skateboard brick body 7 is pushed out of the floating mold frame 21, and the skateboard brick body 7 that has been pressed can be taken out; finally, the floating mold frame 21 and the floating lower mold 4 are driven to reset, waiting for the next pressing work.
