Description

Technical Field

[0001] The present invention relates to the technical field of building prefabricated component production, and more specifically, to a cutting device for producing green building prefabricated components. Background Art

[0002] Existing green buildings are completed by assembly. At present, in addition to the on-site pouring of the main load-bearing structure, reinforced concrete prefabricated parts also include prefabricated floor slabs, prefabricated stairs, prefabricated walls, etc. Prefabricated components refer to various components manufactured by pre-forming methods. Unlike on-site manufacturing, pre-formed components are usually completed in professional factories, then transported to the site for use, and then hoisted and assembled according to the drawings. This method has incomparable advantages in terms of energy saving, water saving, reducing construction waste and saving labor costs. In single-story, multi-story and high-rise buildings, double T-boards can be directly placed on frames, beams or load-bearing walls as floors or roof structures. In single-story industrial plants, double T-boards are used as roof panels and can be placed horizontally on joists or load-bearing walls, or longitudinally on roof beams. Because double T-boards are suitable for larger spans, plants can choose larger spans or column grids to achieve better technical and economic effects.

[0003] However, during production and assembly, the prefabricated parts need to be cut due to the influence of the on-site construction environment. For example, when assembling double T-plate prefabricated panels, the formed double T-plate needs to be cut due to the limitation of the mold size. The double T-plate is mainly composed of reinforced concrete. During the cutting process, it should be considered that the double T-plate is a stress structural member, and the prestressed tendons in the double T-plate cannot be heated. It should also be considered whether the position of the support embedded plate has an impact. When cutting the double T-plate, it was found that due to the built-in steel bars and stones in the double T-shaped plate, and vibration occurred during the cutting process, the side and upper surface of the double T-plate had notches and missing corners at the contact position with the cutting blade during cutting. Although the water flow can cool the cutting tool and take away the cut debris during cutting, the debris on the upper part of the double T-plate is mixed in the cutting seam and on both sides of the cutting tool, causing the cutting tool to swing during cutting. After completion, the cutting surface is uneven, and there are problems of missed cutting and overcutting, resulting in excessive gaps in the later assembly.

[0004] For example, Chinese patent application number 202310306595.2 discloses a cutting device for precast concrete parts, comprising L-shaped plates symmetrically arranged along a horizontal straight line direction, a connecting plate fixedly installed on the top of the vertical sections of the two L-shaped plates, a detachable holding mechanism arranged between the horizontal sections of the two L-shaped plates, displacement grooves symmetrically arranged front and back on the opposite surfaces of the vertical sections of the two L-shaped plates, a limiting mechanism located above the holding mechanism symmetrically arranged front and back between the vertical sections of the two L-shaped plates, a sliding groove for placing a cutting mechanism arranged between the two front and rear displacement grooves on the opposite surfaces of the vertical sections of the two L-shaped plates, and the invention cooperates with a fixed component and a movable component, and the fixed component symmetrically arranged front and back can limit and fix the cutting position to prevent local collapse in the middle of the precast concrete parts during the cutting process, thereby affecting the cutting effect. However, the invention still has the problem that when the rotary cutting knife contacts the surface of the double T-plate to be cut, the double T-plates on both sides of the rotary cutting knife cannot be compacted, and it is impossible to determine whether the rotary cutting knife is deformed, resulting in a gap at the contact position between the upper surface of the double T-plate and the cutting blade, and after the cutting is completed, the cutting plane may be missed or overcut, resulting in an uneven cutting surface.

[0005] To this end, the present invention proposes a cutting device for producing green building prefabricated parts to solve the above problems. Summary of the invention

[0020] Technical effects and advantages of the present invention:

[0021] 1. In the present invention, the gas between the bottom of the buffer and the fourth piston is compressed, so that the product is further buffered when it is placed on the placement table, so that the product is in a stable state before being placed on the placement table. At the same time, negative pressure is formed by the air between the top of the buffer and the fourth piston. When the product is placed on the placement table in accordance with the reference block, the reference block provides limited support for the product, so as to prevent the product from deflecting due to unstable center of gravity during the cutting process, resulting in uneven cutting surface and jamming of the cutting tool.

[0022] 2. The present invention controls the rotation speed of the cutting tool through a third motor, and cools the cutting tool through a cooling unit while cutting the product. At the same time, the debris of the product ground by the cutting tool is washed into the guide groove by cooling water on the placement table, around the cutting tool, and between the product. The mixture of debris and cooling water flows into the collection tray through the guide groove for subsequent cleaning.

[0023] 3. When the product of the present invention falls, the support plate slides in the third guide groove. When the support plate moves, it drives the first piston rod to move. At the same time, the first elastic member is compressed by the support plate. When the first piston rod moves, it drives the first piston to slide in the air collecting member. At the same time, the air at the bottom of the air collecting member is compressed, providing compressed air for the first air cylinder and the second air cylinder. The compressed air is used as the power for the subsequent first clamping block and the second clamping block to clamp the inner and outer sides of the bottom of the product, thereby preventing the product from being deformed due to vibration and torsion, affecting the cutting quality.

[0024] 4. The present invention extrude the third elastic member together with the first wedge block through the fixed plate. The third elastic member is deformed under pressure and extrude the second wedge block at the same time. At the same time, the first wedge block extrude the second wedge block, and the second wedge block moves close to the first wedge block, so that the second wedge blocks located on both sides of the guide groove and the extrusion blocks are close to each other, and pre-pressure is applied to the side of the product to be cut. When the cutting tool cuts the side of the product, a part of the greater impact force at the moment of contact is absorbed by the third elastic member and the second elastic member on both sides of the cutting tool, so that when the cutting tool contacts the side of the product, the vibration generated by the cutting tool is weakened, thereby preventing the side of the product from having notches and uneven cutting surfaces under the action of the cutting tool.

[0025] 5. In the present invention, the fixed column follows the movement of the fixed rod. When the fixed column moves, the resistance value detected by the sliding resistor changes abruptly. The controller reduces the rotation speed of the third motor to cut the product, thereby preventing the cutting tool from generating large vibrations when cutting the steel bars in the product, causing uneven cutting surfaces, overheating of the cutting tool, and excessive wear.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention. Embodiment 1

[0038] In the actual production process, it is found that when the double T-plate is placed on the cutting table by the lifting device, it needs to be repeatedly adjusted to make the cutting tool parallel to the surface to be cut, and when the cutting tool is cutting the double T-plate, the cutting tool grinds and cuts the double T-plate. When the double T-plate is placed on the cutting table, the center of gravity is unstable. Due to the large vibration during the cutting process, the double T-plate is deflected when the cutting tool is cutting the double T-plate, resulting in an uneven cutting surface. In severe cases, the cutting tool is stuck or the motor driving the cutting tool is overloaded, and a lot of working time is wasted in the process of correcting and adjusting the double T-plate. This embodiment is specially invented to solve the above problems.

[0042] When in use, the product 101 is placed on the placement table 31 by a lifting device and cut. In the process of lifting and placing the product 101, one end of the product 101 is moved toward the reference block 32. When the product 101 contacts the reference block 32, the product 101 squeezes the reference block 32 under the action of inertia. The reference block 32 is squeezed by the product 101 and tilts in the notch 315. At the same time, the reference block 32 supports and blocks the product 101, so that the product 101 is not easy to shake in the air, so that the product 101 can be quickly placed on the placement table 31 later. When the reference block 32 tilts, the reference block 32 squeezes the fourth piston rod 36, and the fourth piston rod 36 moves in the buffer 34. When the fourth piston rod 36 moves, it drives the fourth piston 35 to move in the buffer The fourth piston 35 slides inside the buffer 34, and at the same time, the gas between the bottom of the buffer 34 and the fourth piston 35 is compressed, and at the same time, the air between the top of the buffer 34 and the fourth piston 35 forms a negative pressure, and the gas between the bottom of the buffer 34 and the fourth piston 35 is compressed, so that the product 101 is further buffered when it is placed on the placement table 31, so that the product 101 is in a stable state before being placed on the placement table 31, and at the same time, the air between the top of the buffer 34 and the fourth piston 35 forms a negative pressure. When the product 101 is placed on the placement table 31 in accordance with the reference block 32, the reference block 32 limits the support of the product 101 to prevent the product 101 from deflecting due to unstable center of gravity during the cutting process, resulting in an uneven cutting surface and the cutting tool 21 being stuck.

[0043] After the product 101 is adjusted to a good position, the third motor 109 is started to rotate the cutting tool 21 through the transmission mechanism, and the first motor 105 drives the walking block 104 to move on the beam 103. When the walking block 104 moves, the moving plate 106 and the connecting plate 107 are driven to move simultaneously. When the moving plate 106 moves, the cutting part 2 and the cutting tool 21 are driven to move synchronously. The second motor 108 controls the moving plate 106 to move up and down in the walking block 104, and drives the cutting part 2 and the cutting tool 21 to move synchronously. In summary, the cutting tool 2 is controlled by the first motor 105. 1 controls the cutting distance of the product 101, controls the cutting depth of the cutting tool 21 on the product 101 by the second motor 108, controls the rotation speed of the cutting tool 21 by the third motor 109, and cools the cutting tool 21 by the cooling unit 4 while cutting the product 101. At the same time, the debris of the product 101 ground by the cutting tool 21 is washed into the guide groove 311 by cooling water on the placement table 31 and around the cutting tool 21 and between the product 101, and the mixture of the debris and the cooling water flows into the collection tray 38 through the guide groove 311 for subsequent cleaning. Embodiment 2

[0044] When using the above embodiment, it is found that it is far from enough to limit and support the product 101 by the reference block 32 alone. When the product 101 is cut on the workbench by its own gravity, the product 101 generates a large vibration when it contacts the cutting tool 21, especially when the cutting tool 21 cuts the steel bars in the product 101, the vibration is more serious, causing the cutting tool 21 to be skewed during the cutting process. There is also a situation where the cutting tool 21 is stuck in the product 101, causing the cutting tool 21 to rotate at high speed and be heated. When the product 101 vibrates and twists, the cutting tool 21 is deformed, affecting the cutting quality. This embodiment is specially invented to solve the above problems.

One end of each first piston 52 is fixedly connected to a first piston rod 53, and one end of each first piston rod 53 extending out of the air collecting piece 51 is fixedly connected to a support plate 54. Each first piston rod 53 extending out of the outer wall of the air collecting piece 51 is sleeved with a first elastic piece 55, and both ends of each first elastic piece 55 are respectively connected to one end of the air collecting piece 51 and the bottom of the support plate 54, wherein the first elastic piece 55 is a spring.

[0046] See also Figure 3 and Figure 5 As shown, the clamping portion 6 includes a plurality of first clamping blocks 61 and second clamping blocks 62 rotatably connected to the support portion 3, combined with Figure 8 A first guide groove 612 is provided at one end of the bottom of each first clamping block 61, and a first moving member 613 is slidably connected in the first guide groove 612. A second guide groove 622 is provided at one end of the bottom of the second clamping block 62, and a second moving member 623 is slidably connected in the second guide groove 622. The clamping portion 6 also includes a plurality of first gas cylinders 68 and second gas cylinders 69 fixedly connected to the support portion 3. Fig.10 A vent hole is provided at the bottom of each first air cylinder 68, and a second piston 681 is sealed and slidably connected inside each first air cylinder 68. One end of each second piston 681 is fixedly connected to a second piston rod 682, and each second piston rod 682 extends from one end of the corresponding first air cylinder 68 and is fixedly connected to the bottom of the first movable member 613.

[0047] See also Figure 6 and Fig. 9As shown, a vent hole is provided at the bottom of each second air cylinder 69, and a third piston 691 is sealed and slidably connected inside each second air cylinder 69. One end of each third piston 691 is fixedly connected to a third piston rod 692. One end of each third piston rod 692 extends out of the corresponding second air cylinder 69 and is fixedly connected to the bottom of the second movable member 623. The vent holes of the multiple air collecting members 51 are respectively connected to the vent holes of the multiple first air cylinders 68 and the second air cylinders 69 through pipelines, and an exhaust valve is provided in the vent connection pipeline.

[0048] See also Figure 4 As shown, a plurality of third guide grooves 312 for placing the gas collecting member 51 are provided on both sides of the guide groove 311 on the placement table 31, and the third guide grooves 312 are also used for sliding guides of the support plate 54. A plurality of first placement grooves 313 symmetrically distributed along the guide groove 311 are provided in the placement table 31, and the first placement grooves 313 are used for placing the first gas cylinder 68. Second placement grooves 314 corresponding to the first placement grooves 313 are provided on both sides of the placement table 31, and the second placement grooves 314 are used for placing the second gas cylinder 69.

[0049] When used on the basis of the above embodiment, the product 101 is smoothly dropped on the placement table 31 under the guidance of the reference block 32. As the product 101 falls, the bottom structure of the product 101 contacts and presses the support plate 54. As the product 101 falls, the support plate 54 slides in the third guide groove 312. The movement of the support plate 54 drives the first piston rod 53 to move. At the same time, the first elastic member 55 is compressed by the support plate 54. The movement of the first piston rod 53 drives the first piston 52 to slide in the air collecting member 51. At the same time, the air at the bottom of the air collecting member 51 is compressed. The compressed gas at the bottom of the air collecting member 51 is discharged through the pipeline at the same time. When the compressed gas enters the inner bottom of the first gas cylinder 68 and the second gas cylinder 69, the compressed gas at the inner bottom of the first gas cylinder 68 squeezes the second piston 681 to move upward. The second piston 681 moves while driving the second piston rod 682 to move. The second piston rod 682 moves while driving the first movable member 613 to slide in the first guide groove 612. The first movable member 613 slides in the first guide groove 612 while continuously rising, and at the same time, the first clamping block 61 is deflected, so that the first clamping block 61 continuously approaches the bottom inner side of the product 101 and limits the product 101, thereby preventing the product 101 from loosening during cutting.

[0050] At the same time, the compressed gas entering the bottom of the second gas cylinder 69 squeezes the third piston 691 to move upward. The movement of the third piston 691 drives the third piston rod 692 to move. The movement of the third piston rod 692 drives the second movable member 623 to slide in the second guide groove 622. The second movable member 623 continuously rises while sliding in the second guide groove 622, and at the same time causes the second clamping block 62 to deflect, so that the second clamping block 62 continuously approaches the bottom outer side of the product 101 and limits the product 101.

[0051] To summarize, under the guidance of the reference block 32, the product 101 is smoothly placed on the placement table 31, so that when the product 101 falls, the bottom structure of the product 101 contacts and presses the support plate 54, and when the product 101 falls, the support plate 54 slides in the third guide groove 312, and the movement of the support plate 54 drives the first piston rod 53 to move, and the first elastic member 55 is compressed by the support plate 54, and the movement of the first piston rod 53 drives the first piston 52 to slide in the air collecting member 51, and the air at the bottom of the air collecting member 51 is compressed, providing compressed air for the first air cylinder 68 and the second air cylinder 69, and the compressed air is used as the subsequent first clamp The holding block 61 and the second clamping block 62 clamp the inner and outer sides of the bottom of the product 101, thereby preventing the product 101 from being deformed by the cutting tool 21 due to vibration and torsion, which affects the cutting quality; the compressed gas is allowed to enter the inner bottom of the first gas cylinder 68 and the second gas cylinder 69 at the same time through the pipeline, so that the first clamping block 61 and the second clamping block 62 clamp the two sides of the bottom of the product 101 at the same time, further ensuring the stability of the product 101 during the cutting process, and further preventing the cutting tool 21 from cutting the steel bars in the product 101 due to vibration, resulting in the cutting tool 21 being cut deviated during the cutting process and the cutting tool 21 being stuck in the product 101. Embodiment 3

[0052] In actual use, it is found that when the product 101 is fixed and then cut, due to the large radial dimension of the cutting tool 21, when the cutting tool 21 contacts the side of the product 101, due to the large radial dimension of the cutting blade, the cutting tool 21 has a large impact force at the moment of contact with the product 101, resulting in the cutting tool 21 to produce a large vibration when contacting the side of the product 101, resulting in notches on the side cutting surface of the product 101 and uneven cutting plane, resulting in the need for subsequent repair of the assembly surface during later assembly. When the cutting tool 21 cuts the steel bars in the product 101, it will produce a large vibration, which will affect the uneven cutting surface and the overheating and excessive wear of the cutting tool 21. Further improvements are made on the basis of the above embodiments.

[0053] See also Figure 5 and Figure 6As shown, the top of each first clamping block 61 is fixedly connected to a first fastener 611, and the top of each second clamping block 62 is fixedly connected to a second fastener 621. Figure 8 The top of each second fastener 621 is fixedly connected to a fixing plate 63 and a first wedge block 64, each fixing plate 63 is fixedly connected to the corresponding first wedge block 64, the top of each second clamping block 62 is slidably connected to a second wedge block 65 that matches the first wedge block 64, and each second wedge block 65 is fixedly connected to an extrusion block 66 at one end away from the fixing plate 63, and each fixing plate 63 is provided with a plurality of long guide holes 631 at one end away from the first wedge block 64. Fig. 9 , each second wedge block 65 is fixedly connected to a plurality of fixing rods 651 at one end close to the fixing plate 63, and each fixing rod 651 is fixedly connected to a fixing column 652 at one end extending out of the corresponding guide slot 631, wherein the fixing column 652 is connected to a sliding resistor, and the sliding resistor is used to monitor the moving distance of the fixing column 652, and the sliding resistor is connected to the controller. The sliding resistor is a prior art and will not be described in detail here. The outer wall of each fixing rod 651 is sleeved with a second elastic member 67, wherein the second elastic member 67 is a spring, and the two ends of each second elastic member 67 are connected to the fixing column 652. The ends are respectively connected to one end of the corresponding second wedge block 65 and one end of the fixed plate 63, and one end of each first wedge block 64 close to the extrusion block 66 is fixedly connected to the third elastic member 641, wherein the third elastic member 641 is elastic rubber, and the other end of each third elastic member 641 is connected to the extrusion block 66, wherein the second clamping block 62, the second fastener 621 and the contact surface with the product 101 are provided with rubber pads, and the fixed plate 63, the first wedge block 64 and the second wedge block 65 located on both sides of the guide groove 311 are symmetrically arranged.

[0054] On the basis of the above embodiment, when in use, the first clamping block 61 and the second clamping block 62 simultaneously clamp the two sides of the bottom of the product 101, and the first clamping block 61 drives the first fastener 611 to move to further clamp the inner side of the bottom of the product 101, and at the same time, the second clamping block 62 drives the second fastener 621 to move to further clamp the outer side of the bottom of the product 101, so that the product 101 is placed on the placement table 31 more firmly.

[0055] When the second fastener 621 moves, it drives the fixed plate 63 and the first wedge block 64 to move. When the first wedge block 64 moves, it drives the third elastic member 641 to move. When the fixed plate 63 moves, it drives the second wedge block 65 to move through the second elastic member 67, the fixed rod 651 and the fixed column 652. At the same time, the second wedge block 65 drives the extrusion block 66 to move synchronously. When the second fastener 621 is in close contact with the product 101, the extrusion block 66 contacts and presses the upper surface of the product 101. At the same time, the second wedge block 65 and the third elastic member 641 are in close contact with and press the upper side wall of the product 101, thereby ensuring that the position to be cut in the product 101 is in a fastened state before the product 101 contacts the cutting tool 21, thereby preventing the cutting tool 21 from partially absorbing the impact force of the moment of contact with the product 101 by the second fastener 621, thereby preventing the cutting tool 21 from generating large vibrations when it contacts the side of the product 101.

[0056] When the second clamping block 62 continues to clamp the product 101, the rubber pad between the second clamping block 62, the second fastener 621 and the product 101 is further compressed. At the same time, the fixing plate 63 and the first wedge block 64 on both sides of the guide groove 311 squeeze the third elastic member 641, and at the same time squeeze the second wedge block 65 through the first wedge block 64, so that the second wedge blocks 65 and the squeezing blocks 66 on both sides of the guide groove 311 are close to each other. At the same time, the second elastic member 67 is compressed and deformed, and the fixing rod 651 slides in the guide long hole 631, and the fixing column 652 moves with the fixing rod 651, so that the position to be cut in the product 101 is always in a tightened state before the product 101 contacts the cutting tool 21, further preventing the cutting tool 21 from vibrating greatly when it contacts the side of the product 101, resulting in the problem of margin and uneven cutting surface on the side cutting surface of the product 101.

[0057] To sum up, when the cutting tool 21 cuts the side of the product 101, the third elastic member 641 is squeezed by the fixing plate 63 together with the first wedge block 64. The third elastic member 641 is deformed under pressure and squeezes the second wedge block 65 at the same time. At the same time, the first wedge block 64 squeezes the second wedge block 65, and the second wedge block 65 moves along the first wedge block 64, so that the second wedge blocks 65 and the squeezing blocks 66 located on both sides of the guide groove 311 are close to each other, and pre-pressure is applied to the side of the product 101 to be cut. When the cutting tool 21 cuts the side of the product 101, a part of the greater impact force at the moment of contact is absorbed by the third elastic member 641 and the second elastic member 67 on both sides of the cutting tool 21, so that when the cutting tool 21 contacts the side of the product 101, the vibration generated by the cutting tool 21 is weakened, thereby preventing the side of the product 101 from having a notch and an uneven cutting surface under the action of the cutting tool 21.

[0058] When the cutting tool 21 is cutting the product 101, the cutting tool 21 will generate a large vibration when cutting the steel bars in the product 101. At the same time, the third elastic member 641 is further squeezed by the fixing plate 63 together with the first wedge block 64. At the same time, the first wedge block 64 squeezes the second wedge block 65. The third elastic member 641 is compressed and deformed, and further squeezes the second wedge block 65, so that the second wedge blocks 65 on both sides of the guide groove 311 and the squeezing blocks 66 are further close to each other, and the side of the product 101 is continuously clamped. When the second wedge block 65 moves, the second elastic member 67 is compressed and deformed, and the fixed rod 651 slides in the guide long hole 631 and moves along with the fixed rod 651 through the fixed column 652. When the fixed column 652 moves, the resistance value detected by the sliding resistor changes abruptly. The controller reduces the speed of the third motor 109 to cut the product 101, thereby preventing the cutting tool 21 from generating large vibrations when cutting the steel bars in the product 101, causing the cutting surface to be uneven, and the cutting tool 21 to overheat and wear too quickly.
