Abstract
Description
Technical Field
[0001] This utility model relates to the field of auxiliary components for cement board manufacturing, specifically to an auxiliary device for wet cutting and forming of cement boards. Background Technology
[0002] Cement board is a type of building slab made primarily from cement. It is a building product that falls between gypsum board and stone, and can be freely cut, drilled, and carved. It has become a widely used building material in the construction industry due to its superior fire resistance, water resistance, corrosion resistance, insect resistance, and sound insulation properties compared to gypsum board and wood panels, as well as its significantly lower price compared to stone. Cement boards are divided into precast and cast-in-place types. Specifically, in the production of foamed cement boards, wet cutting is performed when the foamed cement board has low strength, which reduces the amount of dust generated during the cutting process, improves cutting efficiency, and significantly improves product quality.
[0003] However, when wet cutting foamed cement boards in a low-strength state, the lack of protection on both sides of the cutting position during the cutting process can easily lead to material damage and deformation on both sides of the cut seam due to excessive cutting impact, as well as seam expansion, resulting in generally poor quality of the cut seam. Utility Model Content
[0004] The purpose of this utility model is to provide an auxiliary device for wet cutting and forming of cement boards in order to solve the above problems, as detailed below.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] The auxiliary device for wet cutting and forming of cement board provided by this utility model includes a cement board body, which is placed flat and the cutting direction is horizontal. At the same time, multiple horizontal cutting marks are provided on the top surface of the cement board body.
[0007] A shaping pressure plate is placed horizontally on the top surface of the cement board body. A slit is opened horizontally on the top surface of the shaping pressure plate. The slit is a through slit in the vertical direction, and the slit is aligned vertically with one of the cutting marks.
[0008] Both sides of the shaping pressure plate are equipped with side pressing components that can slide laterally to adjust the distance between the two sides. The side pressing components are used to limit and press the corresponding outer side of the cement board body from the side to achieve the stability and prevent movement of the shaping pressure plate during the placement of the cement board body on the top surface of the cement board body.
[0009] Both sides of the side pressing assembly are equipped with an adjustment locking assembly, which is used to lock and unlock the lateral position of the side pressing assembly.
[0010] Preferably, the multiple cutting lines are pre-made lines, and the multiple cutting lines are evenly distributed in the longitudinal direction.
[0011] Preferably, the lateral width of the cut is greater than the lateral width of the cement board body.
[0012] Preferably, each of the side pressing components includes a fixing plate, an adjusting stud, and an L-shaped pressing plate. The fixing plate is vertically fixed at the front and rear positions on both sides of the top surface of the shaping plate. Each fixing plate has a guide hole opened in the transverse direction, and the adjusting stud is coaxially inserted into the guide hole in a transverse sliding fit. The end faces of the adjusting studs on both sides that are close to each other are fixedly connected to the L-shaped pressing plate. The L-shaped pressing plate is inverted and the vertical part is located on the outer side of the corresponding side of the cement board body. The adjusting locking component is assembled on the outer side of each fixing plate, and the adjusting locking component is coaxially arranged around the adjusting stud.
[0013] Preferably, the inner corners of the L-shaped top pressure plate are in contact with the corresponding edges of the shaping pressure plate, and the lowest position of the L-shaped top pressure plate is higher than the bottom surface of the cement board body.
[0014] Preferably, the method of connecting the adjusting stud and the L-shaped top pressure plate is as follows: a connecting sleeve is welded to the outer surface of the L-shaped top pressure plate, and the connecting sleeve is coaxially interference-fitted with the corresponding adjusting stud.
[0015] Preferably, each of the adjusting studs on the same side is fixedly connected to a connecting end plate, and a handle for easy gripping is assembled on the outer side of each connecting end plate.
[0016] Preferably, the axial length of each adjusting stud is at least one-quarter of the transverse dimension of the cut.
[0017] Preferably, each of the adjusting locking components includes a guide sleeve and a clamping stud. The guide sleeve is fixedly connected to the outer side of each fixing plate, and the adjusting stud passes through the corresponding guide sleeve in a lateral sliding fit. The upper outer periphery of each guide sleeve is provided with a vertical mounting hole. The mounting holes are all through holes, and the clamping stud is coaxially inserted into each mounting hole in a threaded fit.
[0018] Preferably, the bottom end of each clamping stud is coaxially fixed with an elastic pressure block whose outer diameter is smaller than that of the mounting hole, and the top end of each clamping stud is coaxially fixed with an end for easy gripping.
[0019] Using the aforementioned cement board wet cutting and forming auxiliary device, specifically in the process of cutting the cement board body in a low-strength state, after marking the cutting lines at intervals on the top surface of the cement board body, the shaping pressure plate is pressed onto the top surface of the cement board body, and the cut is aligned with the cutting lines. This method utilizes the shaping pressure plate to provide material positioning and protection for the cement board body on both sides of the cutting lines, preventing damage, deformation, and gap expansion of the material on both sides of the cutting lines during the cutting process. This improves the cutting and forming quality of the cement board body. Furthermore, since the side pressing components are combined on both sides of the shaping pressure plate, and the L-shaped pressing plates of the side pressing components limit and press the corresponding outer side of the cement board body from the side, the shaping pressure plate can be stably prevented from moving during placement on the top surface of the cement board body. This prevents the shaping pressure plate from shifting during the cutting process, thus avoiding changes in the cut position and further improving the cutting and forming quality of the cement board body. Moreover, because... The adjusting stud of the side pressing assembly slides laterally along the guide hole and is locked by the adjusting locking assembly, allowing adjustment of the distance between the L-shaped pressing plates on both sides. This facilitates smooth pressing of the L-shaped pressing plates against the sides of the cement slab body. It also allows for adaptive adjustment of the distance between the L-shaped pressing plates based on the lateral width of the cement slab body, improving the usability of the shaping plate and the side pressing assembly. Furthermore, tightening the adjusting locking assembly... The aforementioned clamping stud method can lock the adjusting stud from sliding along the guide sleeve, thereby locking the positions of the adjusting stud and the L-shaped top pressure plate. At the same time, the locking state of the adjusting stud being unable to slide along the guide sleeve can be released simply by loosening the clamping stud. The locking and unlocking method of the adjusting stud sliding along the guide sleeve is simple and easy to implement. It is convenient to lock in time when the adjusting stud is adjusted to the position by sliding along the guide sleeve, and it is also convenient to allow the adjusting stud to smoothly drive the L-shaped top pressure plate to adjust its position after unlocking.
[0020] The beneficial effects are as follows: 1. After marking the cutting lines at intervals on the top surface of the cement board body, this utility model uses a shaping plate to press the top surface of the cement board body and make the cut align with the cutting lines. This method can use the shaping plate to help position and protect the cement board body on both sides of the cutting lines, avoiding damage, deformation and gap expansion of the material on both sides of the cutting lines during the cutting process, which is conducive to improving the cutting and forming quality of the cement board body.
[0021] 2. Side pressing components are combined on both sides of the shaping plate. The L-shaped pressing plate of the side pressing component presses down on the corresponding outer side of the cement board body from the side, which can realize the stability of the shaping plate during the placement of the shaping plate on the top surface of the cement board body. This avoids the situation where the shaping plate shifts during the cutting process, which would cause the cutting position to change. This is conducive to further improving the cutting and forming quality of the cement board body.
[0022] 3. By adjusting the studs of the side pressing assembly and sliding them laterally along the guide hole and locking them with the adjusting locking assembly, the distance between the L-shaped pressing plates on both sides can be adjusted. This allows the L-shaped pressing plates on both sides to press smoothly against the side of the cement board body. It also allows for adaptive adjustment of the distance between the L-shaped pressing plates on both sides according to the lateral width of the cement board body, thus improving the applicability of the shaping pressing plate and the side pressing assembly.
[0023] 4. By tightening the clamping stud of the adjusting locking assembly, the adjusting stud can be locked from sliding along the guide sleeve. This locks the position of the adjusting stud and the L-shaped top pressure plate. Loosening the clamping stud releases the lock that prevents the adjusting stud from sliding along the guide sleeve. The locking and unlocking method for the adjusting stud sliding along the guide sleeve is simple and easy to implement. It is convenient to lock the adjusting stud in time when it is adjusted to the correct position by sliding along the guide sleeve, and it is also convenient to allow the adjusting stud to smoothly drive the L-shaped top pressure plate to adjust its position after unlocking.

[0034] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0035] See Figures 1-7 As shown, this utility model provides a cement board wet cutting and forming auxiliary device, including a cement board body 1, which is placed horizontally with the cutting direction along the transverse direction. Multiple transverse cutting marks 101 are provided on the top surface of the cement board body 1. A shaping pressure plate 2 is placed horizontally on the top surface of the cement board body 1, and a slit 201 is opened horizontally on the top surface of the shaping pressure plate 2. The slit 201 is a through slit in the vertical direction, and the slit 201 is aligned vertically with one of the cutting marks 101. The purpose of this arrangement is that after the cutting marks 101 are marked at intervals on the top surface of the cement board body 1, by pressing the shaping pressure plate 2 onto the top surface of the cement board body 1 and aligning the slit 201 with the cutting marks 101, the shaping pressure plate 2 can be used to provide material auxiliary positioning and protection for the cement board body 1 at both sides of the cutting marks 101.
[0036] See Figures 1-4As shown, the shaping pressure plate 2 is equipped with side pressing components 3 on both sides, which can be laterally slidably adjusted to prevent movement during placement on the top surface of the cement board body 1. Specifically, each side pressing component 3 includes a fixing plate 304, an adjusting stud 303, and an L-shaped pressing plate 305. The front and rear positions on both sides of the top surface of the shaping pressure plate 2 are vertically fixed with fixing plates 304. Each fixing plate 304 has a guide hole 307 laterally, and the adjusting stud 303 is coaxially inserted into the guide hole 307 in a laterally sliding manner. The adjustment of the side positions... L-shaped top pressure plates 305 are fixedly connected to the end faces of the studs 303 that are close to each other. The L-shaped top pressure plates 305 are all inverted and the vertical parts are all located on the outer side of the corresponding side of the cement board body 1. Adjustment locking components 4 are all assembled on the outer side of the fixing plate 304. The adjustment locking components 4 are coaxially arranged around the adjusting studs 303. The purpose of this arrangement is to ensure that the shaping pressure plate 2 is stable and prevented from moving during the placement of the shaping pressure plate 2 on the top surface of the cement board body 1 by limiting and pressing the corresponding outer side of the cement board body 1 from the side by the L-shaped top pressure plate 305 of the side top pressure component 3. This avoids the situation where the position of the cut slit 201 changes due to the displacement of the shaping pressure plate 2 during the cutting process.
[0037] See Figures 1-7 As shown, the side pressing components 3 on both sides are equipped with adjusting locking components 4, which are used to lock and unlock the lateral position of the side pressing components 3 by adjusting the locking components 4. Specifically, each adjusting locking component 4 includes a guide sleeve 404 and a clamping stud 402. The guide sleeve 404 is fixedly connected to the outside of the fixing plate 304, and the adjusting stud 303 passes through the corresponding guide sleeve 404 coaxially in a lateral sliding fit. The upper part of the outer periphery of each guide sleeve 404 is vertically provided with a mounting hole 403. The mounting holes 403 are all through holes, and the clamping stud 402 is coaxially inserted into each mounting hole 403 in a threaded fit. The reason for this arrangement is that the through holes 403 are through holes. By sliding the adjusting stud 303 of the side pressing assembly 3 laterally along the guide hole 307 and locking it through the adjusting locking assembly 4, the distance between the L-shaped pressing plates 305 on both sides can be adjusted. More specifically, by tightening the clamping stud 402 of the adjusting locking assembly 4, the adjusting stud 303 can be prevented from sliding along the guide sleeve 404, thereby locking the position of the adjusting stud 303 and the L-shaped pressing plate 305. At the same time, the locking state of the adjusting stud 303 being unable to slide along the guide sleeve 404 can be released simply by loosening the clamping stud 402. The method of locking and unlocking the sliding of the adjusting stud 303 along the guide sleeve 404 is simple and easy to implement.
[0038] See Figures 1-7As shown, the following more detailed optimizations have been made to this scheme. Specifically, the multiple cutting marks 101 are pre-made marks, and the multiple cutting marks 101 are evenly distributed in the longitudinal direction to facilitate the cutting of the cement board body 1 into multiple pieces by referring to the multiple cutting marks 101. Optionally, the transverse width of the slit 201 is larger than the transverse width of the cement board body 1, so that the slit 201 has a suitable transverse length to ensure that it can meet the needs of cutting the cement board body 1. Further optionally, the inner corners of the L-shaped top pressure plate 305 are in contact with the corresponding corners of the shaping pressure plate 2, and the lowest position of the L-shaped top pressure plate 305 is higher than the bottom surface of the cement board body 1. This setting facilitates the L-shaped top pressure plate 305 to be guided and corrected by moving along the corresponding corners of the cement board body 1 through the inner corners, and also prevents the bottom edge of the L-shaped top pressure plate 305 from interfering with the smooth sliding adjustment position.
[0039] See Figures 1-7 As shown, the fixed connection method between the adjusting stud 303 and the L-shaped top pressure plate 305 is as follows: a connecting sleeve 306 is welded to the outer surface of the L-shaped top pressure plate 305, and the connecting sleeve 306 is coaxially interference-fitted with the corresponding adjusting stud 303. This setting facilitates the quick combination of the L-shaped top pressure plate 305 and the adjusting stud 303 using the connecting sleeve 306. Optionally, a connecting end plate 301 is fixedly connected to the outer end of each adjusting stud 303 on the same side, and a handle 302 for easy gripping is installed on the outer side of each connecting end plate 301. This setting facilitates the connection of the adjusting studs 303 on the same side into one unit using the connecting end plate 301, preventing the adjusting studs 303 from rotating around the guide hole 307 and allowing the entire device to be lifted and moved by applying force by gripping the handle 302 when changing the cutting position. Optionally, the axial length of the adjusting stud 303 is at least one-quarter of the transverse dimension of the slit 201, so that the adjusting stud 303 can drive the L-shaped top pressure plate 305 to have a larger sliding adjustment space. Furthermore, the bottom end of the clamping stud 402 is coaxially fixed with an elastic pressure block 405 with an outer diameter smaller than the diameter of the mounting hole 403, and the top end of the clamping stud 402 is coaxially fixed with an end head 401 for easy gripping. With this arrangement, it is easy to improve the locking stability of the adjusting stud 303 by elastically pressing it against the outer periphery of the adjusting stud 303 with the elastic pressure block 405, and it is easy to tighten the clamping stud 402 by applying force by gripping the end head 401.
[0040] Using the above structure, specifically in the process of cutting a cement board body 1 in a low-strength state, after marking the cutting lines 101 at intervals on the top surface of the cement board body 1, by pressing the shaping pressure plate 2 on the top surface of the cement board body 1 and aligning the cut slit 201 with the cutting lines 101, the shaping pressure plate 2 can provide material auxiliary positioning and protection for the cement board body 1 on both sides of the cutting lines 101. This avoids damage, deformation, and gap expansion of the material on both sides of the cutting lines 101 during the cutting process, which is beneficial to improving the protection of the cement board body. The cutting and forming quality of the cement board body 1 is improved. Since the shaping pressure plate 2 is equipped with side pressing components 3 on both sides, and the L-shaped pressing plates 305 of the side pressing components 3 limit and press the corresponding outer side of the cement board body 1 from the side, the shaping pressure plate 2 can be stably prevented from moving during the placement of the shaping pressure plate 2 on the top surface of the cement board body 1. This avoids displacement of the shaping pressure plate 2 during the cutting process, which would cause changes in the position of the cut slit 201. This further improves the cutting and forming quality of the cement board body 1. Furthermore, the adjusting studs 303 of the side pressing components 3 are used to adjust the cutting quality of the cement board body 1. The guide hole 307 slides laterally and is locked by the adjusting locking assembly 4, which allows the distance between the L-shaped top pressure plates 305 on both sides to be adjusted. This facilitates the smooth pressing of the L-shaped top pressure plates 305 against the sides of the cement board body 1. It also allows for adaptive adjustment of the distance between the L-shaped top pressure plates 305 according to the lateral width of the cement board body 1, improving the usability of the shaping pressure plate 2 and the side pressing assembly 3. Furthermore, the adjusting locking assembly 4 locks the distance between the L-shaped top pressure plates 305 by tightening the clamping stud 402. The adjusting stud 303 cannot slide along the guide sleeve 404, thus locking the position of the adjusting stud 303 and the L-shaped top pressure plate 305. At the same time, the locking state of the adjusting stud 303 not being able to slide along the guide sleeve 404 can be released simply by loosening the clamping stud 402. The locking and unlocking method of the adjusting stud 303 sliding along the guide sleeve 404 is simple and easy to implement. It is convenient to lock the adjusting stud 303 in time when it slides along the guide sleeve 404 to adjust to the correct position, and it is also convenient to allow the adjusting stud 303 to smoothly drive the L-shaped top pressure plate 305 to adjust its position after unlocking.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
