Description

Technical Field

[0001] This invention relates to the field of building construction technology, specifically to a high-strength aerated concrete block cutting and forming device. Background Technology

[0002] In the process of building construction and decoration, concrete blocks are often used for building. Aerated concrete blocks are a lightweight, porous silicate building material made by introducing countless tiny, independent air bubbles into concrete. They are relatively brittle when placed on the ground and are widely used in non-load-bearing walls.

[0003] However, in actual production, prefabricated aerated concrete blocks are long and narrow, making transportation inconvenient and unsuitable for later construction environments. Therefore, they need to be cut to standard sizes. However, due to different construction requirements, the required cutting dimensions vary, necessitating adjustments to the cutting length. Common methods include fixing the aerated concrete block and adjusting the cutting tool, or fixing the cutting tool and adjusting the aerated concrete block. This can cause positional conflicts between the aerated concrete block support and the cutting tool. When the cutting position happens to be located at the support of the aerated concrete block, reinstallation and adjustment are required, thus limiting its adaptability and affecting processing efficiency. Summary of the Invention

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Please see Figures 1 to 8 The present invention provides a technical solution:

[0030] A high-strength aerated concrete block cutting and forming device includes a cutting frame 1, a push frame 2 connected and driven by a telescopic push rod 6 on the cutting frame 1, a longitudinally and transversely distributed slide groove assembly on the upper surface of the base of the cutting frame 1, multiple sets of fixed modules 3 spaced apart installed at the lower end of the push frame 2, a laterally adjustable cutting module 4 slidably installed on the upper end of the cutting frame 1, and a slider 25 adapted to the slide groove assembly at the lower end of the fixed module 3. The slide groove assembly includes longitudinal slide grooves 14 and transverse slide grooves 15 that are crisscrossed. The longitudinal slide grooves 14 and transverse slide grooves 15 are staggered to form a switching groove 16. There are two sets of transverse slide grooves 15, which correspond to a pair of sliders 25 at the lower end of the fixed module 3, respectively. The sliders 25 can rotate circumferentially within the switching groove 16. There are multiple sets of longitudinal slide grooves 14, and the multiple sets of longitudinal slide grooves 14 correspond one-to-one with multiple sets of right-angle frames 7 on the push frame 2.

[0031] When installing the fixed module 3, the fixed module 3 is inserted into the cutting frame 1 by using the cooperation of the slider 25 and the transverse slide 15. The appropriate interval and position are selected to avoid the cutting range and push it to the position corresponding to the right angle frame 7 on the push frame 2. At this time, the slider 25 is located at the position of the switching slot 16.

[0032] The upper end of the slider 25 is provided with a rotating shaft 23 that is rotatably inserted into the inner cavity of the lower end of the fixed module 3. A second gear 24 is fixedly sleeved on the rotating shaft 23. A toothed plate 26 parallel to the rotating rod 21 is elastically inserted into the inner cavity of the lower end of the fixed module 3. The toothed plate 26 is provided with teeth that mesh with the second gear 24.

[0033] The toothed plate 26 drives the second gear 24 to mesh and rotate, which in turn drives the rotating shaft 23 to rotate. This causes the slider 25 to rotate in the switching groove 16 with an adjusted angle, so that it faces the longitudinal groove 14. The slider 25 and the longitudinal groove 14 cooperate to adapt to the pushing and cutting of the concrete brick 5.

[0034] A main shaft 20 driven by a second motor 18 is mounted on the fixed module 3. A support roller 10 for supporting concrete bricks 5 is mounted on the main shaft 20. A clamping ring 12 for clamping one end face of the concrete brick 5 is elastically sleeved at the end of the main shaft 20. An externally threaded tube 11 is provided on the inner wall of the fixed module 3 away from the push frame 2. The main shaft 20 is rotatably inserted into the externally threaded tube 11. An adjusting screw ring 13 is rotatably installed on the outer thread of the externally threaded tube 11. One end of the adjusting screw ring 13 abuts against the clamping ring 12. On one side, a clamping plate 38 is provided at the upper end of the clamping ring 12 and pressed against the end face of the concrete brick 5. The clamping ring 12 is slidably sleeved on the main shaft 20. The support roller 10 is fixedly sleeved on the main shaft 20. A third spring 43 is pressed between the end of the support roller 10 and the clamping ring 12. A toothed ring 36 is fixedly installed on the outer arc of the adjusting screw ring 13. A rotating rod 21 is rotatably installed in the inner cavity of the lower end of the fixed module 3. A first gear 22 that meshes with the toothed ring 36 is fixedly sleeved on the rotating rod 21.

[0035] Driven by the rotating rod 21, the first gear 22 rotates, which in turn drives the gear ring 36 to rotate circumferentially. The traction adjusting screw ring 13 is pushed into the external threaded tube 11 with a small amplitude, thereby squeezing the clamping ring 12 and making the clamping plate 38 tightly pressed against one end face of the concrete brick 5, forming a clamp that cooperates with the push frame 2.

[0036] The cutting module 4 includes a turntable 28 located at the upper end of the cutting frame 1 and a mounting base 35 located at the lower end of the cutting frame 1. A cutting blade 32 is vertically and elastically mounted between the turntable 28 and the mounting base 35. The cutting blade 32 faces the concrete brick 5. The turntable 28 is provided with a rotating interval pressing protrusion 31 on the upper end of the cutting blade 32. Both the upper and lower ends of the cutting blade 32 are provided with end plates 29. A first spring 30 is pressed on both the upper and lower end plates 29 of the cutting blade 32. A pressing groove 41 is provided on the end plate 29 of the cutting blade 32 near the turntable 28. The turntable 28 is driven by a first motor 17. The protrusion 31 at the lower end of the turntable 28 is intermittently pressed on the pressing groove 41 by circumferential rotation.

[0037] The first motor 17 drives the turntable 28 to rotate, so that the protrusion 31 intermittently squeezes the end plate 29 at the end of the cutting blade 32 as it rotates in a circle. During the squeezing, the cutting blade 32 descends and squeezes the first spring 30. When the protrusion 31 moves away, the cutting blade 32 rises under the restoring force of the first spring 30, thus forming a reciprocating motion. In the reciprocating motion of the cutting blade 32, the longitudinally advancing concrete brick 5 is cut.

[0038] The push frame 2 is provided with a T-shaped slot 40, and the fixed module 3 is provided with a plug block 37 that mates with the slot 40. A pin 27 is slidably provided on the side of the push frame 2 near the telescopic push rod 6. A pin hole 42 is provided through the end face of the slot 40 and the plug block 37 facing the pin 27. The pin 27 can be inserted into the pin hole 42. The fixing part 9 includes a stud and a nut. The stud is fixed on the outer end face of the right angle frame 7. A handle is provided on the linkage frame 8. The linkage frame 8 and the handle are sleeved through the stud and locked by rotating the nut installed on the stud.

[0039] The fixed module 3 is installed by the cooperation of the slot 40 and the plug 37, and the position is locked by the cooperation of the pin 27 and the pin hole 42.

[0040] The push frame 2 is provided with multiple sets of spaced right-angle frames 7 on the side near the telescopic push rod 6. The right-angle frame 7 is provided with a linkage frame 8 that can be detached and installed by a fastener 9. The pin 27 is fixed to the linkage frame 8. The end of the rotating rod 21 is provided with a hexagonal prism-shaped rotating head 19. The linkage frame 8 is rotatably mounted with a rotating handle 34 that can be sleeved on the rotating head 19. The toothed plate 26 extends to the outside of the fixed module 3 at the end near the push frame 2, and the end of the toothed plate 26 is sleeved with a second spring 39. The linkage frame 8 is provided with a push rod 33 facing the end of the toothed plate 26.

[0041] By setting up the linkage frame 8, the fixing of the fixed module 3, the clamping of the concrete brick 5, and the angle switching of the slider 25 are integrated in a unified manner, which greatly simplifies the operation.

[0042] Working principle: First, by using the cooperation of slider 25 and transverse slide 15, the fixed module 3 is inserted into the cutting frame 1. A suitable interval and position are selected to avoid the range corresponding to the cutting size. It is pushed to the position corresponding to the right angle frame 7 on the push frame 2. At this time, slider 25 is located at the position of switching slot 16. At this time, the drive linkage frame 8 is inserted and fixed by the fixing part 9. During the insertion process, the pin 27 is inserted into the pin hole 42. The push rod 33 presses the end of the toothed plate 26, drives the toothed plate 26 to slide, drives the second gear 24 to rotate, so that slider 25 completes the angle adjustment, thereby making the position of slider 25 fit the longitudinal slide 14. At the same time, the rotating handle 34 is sleeved on the rotating head 19. Then, concrete brick 5 is put in. By rotating the rotating handle 34, the clamping ring 12 is pushed forward to achieve clamping of concrete brick 5.

[0043] After clamping, the position of the cutting module 4 is adjusted according to the cutting size. During the cutting process, the first motor 17 drives the turntable 28 to rotate, so that the protrusion 31 intermittently squeezes the cutting blade 32, realizing the up-and-down reciprocating motion of the cutting blade 32. With the advancement of the telescopic push rod 6, the push frame 2 and the fixed module 3 slide synchronously along the longitudinal slide groove 14, driving the concrete brick 5 to move towards the cutting blade 32 to achieve cutting.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
