Description

Technical Field

[0001] The utility model relates to the technical field of brick presses, in particular to a device for removing burrs of clay bricks. Background Art

[0002] Refractory clay bricks have excellent fire resistance, corrosion resistance and mechanical strength, and are widely used in various high-temperature environments such as industrial equipment, furnaces and buildings.

[0003] The existing production process of refractory clay bricks generally requires ingredient mixing, die-casting, air drying and sintering, among which the burrs of clay bricks generally appear in the die-casting process. In actual production, if the burrs generated in the die-casting process are not removed in time, the edges and corners of the clay bricks may be missing in the subsequent processes, affecting the quality of the clay bricks.

[0004] like Figure 1 The brick press commonly used in the die-casting process of refractory clay bricks shown in the figure and its cross-sectional view include a die-casting component 1, a filling frame 2 and a clamping arm 3. The die-casting component 1 includes an upper pressure head 11, a middle mold 12 and a bottom plate 13. The filling frame 2 is movable. During the movement of the filling frame 2, the raw materials are filled into the cavity between the middle mold 12 and the bottom plate 13, and the upper pressure head 11 is pressed into the middle mold 12 to die-cast the clay brick. The lifting device connected to the bottom plate 13 lifts the clay brick so that it can be clamped by the clamping arm 3, and is further driven by the movement of the filling frame 2 to clamp the clay brick and put it into the conveyor belt.

[0005] In the above-mentioned die-casting process, since the upper ram 11 and the bottom plate 13 can slide up and down compared with the middle mold 12, it is inevitable that there will be gaps between the upper ram 11 and the middle mold 12, and between the bottom plate 13 and the middle mold 12. Therefore, the burrs of the clay bricks appear in the gaps between the upper ram 11 and the middle mold 12, and between the bottom plate 13 and the middle mold 12; and at this time, the brick blanks are fragile and easy to deform, and are not suitable for grinding the burrs using a grinding device; and, if the brick blanks are transferred, the burrs will break and there is a certain probability that the corners will be missing material, which will affect the quality of the clay bricks. Therefore, a device that can accurately remove the burrs of clay bricks during the die-casting process is needed. Utility Model Content

[0025] The utility model will be described in detail below with reference to the drawings and in conjunction with the embodiments. It should be noted that, without conflict, the embodiments in the utility model and the features in the embodiments can be combined with each other.

[0026] As Figures 1 to 6 shown in the embodiment of the clay brick burr removing device of the utility model, the clay brick burr removing device includes a fixing frame 4, a driving assembly 5 and a scraper bar assembly 6. The fixing frame 4 is fixedly arranged on the side wall of the filling frame 2 facing the die-casting assembly 1. The clamping arms 3 are fixedly arranged on the side wall of the fixing frame 4 facing the die-casting assembly 1. The filling frame 2 can move in the direction facing the die-casting assembly 1. The die-casting assembly 1 can move in the direction perpendicular to the horizontal plane to complete the die-casting and jacking up of the brick blank. The driving assembly 5 and the scraper bar assembly 6 are arranged on the fixing frame 4.

[0027] For the convenience of understanding and expression, in this embodiment, the moving direction of the filling frame 2 is set as the x-axis, the moving direction of the die-casting assembly 1 is set as the z-axis, and the direction perpendicular to both the x-axis and the z-axis is the y-axis.

[0028] The driving component 5 can drive the scraping rod component 6 to slide along the length direction (y-axis) of the fixing frame 4. The length direction of the fixing frame 4 is perpendicular to the moving direction (x-axis) of the stuffing box 2 and perpendicular to the moving direction (z-axis) of the die-casting component 1. Specifically, the scraping rod component 6 includes a lower scraping rod 61, a connecting rod 62, and an upper scraping rod 63. The lower scraping rod 61 and the connecting rod 62 are fixedly connected to the driving component 5. The upper scraping rod 63 is slidably arranged on the connecting rod 62. The lower scraping rod 61 and the upper scraping rod 63 are parallel to the moving direction of the stuffing box 2. Scraping knives 64 are fixedly arranged on the end faces of the lower scraping rod 61 and the upper scraping rod 63 facing each other. When sliding along the length direction of the fixing frame 4, the scraping knives 64 can remove the burrs of the clay bricks. Since the brick blanks are fragile and not suitable for using a grinding device to grind the burrs, using scraping knives 64 with a suitable height can effectively remove the burrs.

[0029] The die-casting component 1 includes an upper punch 11, a middle mold 12, and a bottom plate 13. After the bottom plate 13 sends the die-cast brick blank upward to a specific position, the clamping arms 3 (along the y-axis) act on both side faces of the brick blank to clamp the brick blank, and the bottom plate 13 returns to its original position. At this time, the detailed position of the brick blank is the most determinable. During the subsequent movement of the clamping arms 3 under the action of the stuffing box 2 (along the x-axis) to place the brick blank on the conveyor belt, the position of the brick blank will change slightly due to various factors. Moreover, when the brick blank is placed on the conveyor belt, there is a possibility that the burrs will break and there is a certain probability that the corners will be missing due to the burrs.

[0030] In this embodiment, the height (z-axis) of the scraping knife 64 on the lower scraping rod 61 of the scraping rod component 6 is fixedly set, and this height is flush with the upper surface of the bottom plate 13 when it rises to the highest position. Specifically, it can be adjusted by adjusting the rising height of the bottom plate 13. The scraping knife 64 on the upper scraping rod 63 adjusts its height by sliding the upper scraping rod 63 up and down on the connecting rod 62. Specifically, it can be adjusted according to the thickness of different types of brick blanks. In this way, the scraping rod component 6 can adapt to brick blanks of different thicknesses and effectively remove the burrs of the brick blanks.

[0031] Based on the above situation, therefore, when the clamping arms 3 (along the y-axis) act on both side faces of the brick blank to clamp the brick blank, using the driving component 5 to drive the lower scraping rod 61 and the upper scraping rod 63 of the scraping rod component 6 can accurately remove the burrs generated on the upper and lower end faces of the clay brick blanks due to die-casting, and can effectively improve the quality of the clay bricks.

[0032] In an embodiment of the present application, preferably, the driving assembly 5 includes a motor 51, a lead screw 52, and a slider 53. The motor 51 drives the lead screw 52 to rotate. The lead screw 52 is disposed through the fixing frame 4 along the length direction of the fixing frame 4. The slider 53 is sleeved on the lead screw 52 and slides in the sliding cavity 4a of the fixing frame 4 when the lead screw 52 rotates. The lower scraping rod 61 and the connecting rod 62 are fixedly connected to the slider 53. Bearings 41 are provided at both ends of the lead screw 52, and the bearings 41 are fixedly disposed at both ends of the fixing frame 4 in the sliding cavity 4a. Thus, the driving assembly 5 can drive the scraping rod assembly 6 to slide along the length direction (y-axis) of the fixing frame 4.

[0033] In an embodiment of the present application, preferably, an upper sliding groove 4b and a lower sliding groove 4c communicating with the sliding cavity 4a are further provided in the fixing frame 4. The connecting rod 62 slides in the upper sliding groove 4b, and the lower scraping rod 61 slides in the lower sliding groove 4c. The upper sliding groove 4b extends out of the upper surface of the fixing frame 4, and the lower sliding groove 4c extends out of the side surface of the fixing frame 4. Thus, effective support is provided for the sliding of the lower scraping rod 61 and the connecting rod 62.

[0034] In an embodiment of the present application, preferably, the lengths of the lower scraping rod 61 and the upper scraping rod 63 extending towards the stuffing box 2 are greater than those of the clamping arms 3. The lower scraping rod 61 is lower than the clamping arms 3, and the upper scraping rod 63 is higher than the clamping arms 3, that is, the scraping rod assembly 5 surrounds the clamping arms 3 to prevent interference between the scraping rod assembly 5 and the clamping arms 3 when the scraping rod assembly 5 slides.

[0035] In an embodiment of the present application, preferably, a reinforcing rod 611 is provided at one end of the lower scraping rod 61 away from the fixing frame 4. The reinforcing rod 611 extends vertically upward, and the upper scraping rod 63 can slide up and down along the reinforcing rod 611. Thus, support can be provided for the upper scraping rod 63 to improve the accuracy when removing burrs.

[0036] In an embodiment of the present application, preferably, adjusting blocks 631 are provided at both ends of the upper scraping rod 63. The adjusting blocks 631 are respectively sleeved on the connecting rod 62 and the reinforcing rod 611. Fixing measures such as rotating rods fixedly connected to the connecting rod 62 or the reinforcing rod 611 can be provided on the adjusting blocks 631 to effectively support the upper scraping rod 63.

[0037] In an embodiment of the present application, preferably, a slide rail 7 is further included. The slide rail 7 is fixedly disposed at the top end of the fixing frame 4. The length direction of the slide rail 7 is parallel to the length direction of the fixing frame 4. A convex block 632 that can be embedded in the slide rail 7 is provided at the lower end of the upper scraping rod 63. The slide rail 7 can provide support for the upper scraping rod 63 and ensure that the upper scraping rod 63 remains straight in the sliding direction during sliding, improving the accuracy when removing burrs.

[0038] In an embodiment of the present application, preferably, a backing plate 71 is fixedly provided between the slide rail 7 and the fixing bracket 4. The backing plate 71 is used to adjust the height of the slide rail 7. When it is necessary to adjust the height of the upper scraping rod 63, in addition to sliding the upper scraping rod 63 up and down on the connecting rod 62 and the reinforcing rod 611, backing plates 71 with different heights can also be replaced to enable the slide rail 7 to provide effective support for the upper scraping rod 63.

[0039] In an embodiment of the present application, preferably, as Figure 5 shown, there is a gap between the scraping blade 64 and the lower scraping rod 61 or the upper scraping rod 63 where it is located. The scraping blade 64 is fixedly connected to the lower scraping rod 61 or the upper scraping rod 63 through a plurality of fixing rods 641. In this way, when the scraping blade 64 removes burrs, the impurities removed will not accumulate at the scraping blade 64.

[0040] In an embodiment of the present application, preferably, the scraping blade 64 is inclined, and the cutting edge of the scraping blade 64 is farther away from the lower scraping rod 61 or the upper scraping rod 63 where it is located than its back. In this way, the cutting edge can directly act on the burrs, improving the accuracy of burr removal.
