Description

Technical Field

[0001] The present invention relates to the technical field of auxiliary forming of prefabricated building components, and specifically relates to an auxiliary forming device for prefabricated building components. Background Technique

[0002] In the field of prefabricated buildings, hexagonal bricks are widely used in road surfaces and decorative components. As a kind of concrete precast member, the production quality and efficiency of hexagonal bricks directly affect the project cost and construction progress. In the traditional forming process of hexagonal bricks, the demolding link has long relied on the method of manually hitting a rubber tire. The specific process is as follows: Workers pour concrete into a hexagonal mold, then let it stand for curing until the initial setting, then manually lift the mold, and finally smash it forcefully onto the surface of the rubber tire to separate the brick body from the mold through impact vibration. Although this method has been used in small and medium-sized building material factories for decades, with the increasing demand for the upgrading of building industrialization, its technical pain points have become increasingly prominent, and the specific defects are as follows: 1. Low operation efficiency: Multiple workers need to cooperate in a single demolding operation, and workers repeat the hitting action for a long time, which is easy to cause fatigue, with low production capacity, unable to match the rhythm of the automated production line. At the same time, the hitting action has a certain degree of danger.

[0003] 2. Unstable demolding success rate: It depends on the worker's experience to judge the hitting force and angle, and the breakage rate of the brick body is relatively high. The hardness of the rubber tire is affected by temperature (the difference between summer and winter reaches 15% Shore hardness), resulting in fluctuations in the demolding force.

[0004] 3. Material loss: The hitting impact causes the edges of the concrete to break off, resulting in material loss. Summary of the Invention

Detailed implementation manners

[0026] To make the above objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention in conjunction with the accompanying drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described below, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific implementation manners disclosed below.

[0027] Refer to Figure 1 , Figure 2 and Figure 6 , an auxiliary forming device for precast building components, including a mounting plate 1 fixedly connected to the execution end of a robotic arm. A fixed limiting rod 2 is fixedly connected to the bottom end of the mounting plate 1. The bottom end of the fixed limiting rod 2 is fixedly connected to an inner connecting part 21 through a first fixing ring. The inner connecting part 21 is used for adsorbing and fixing the inner side wall of the forming die; an outer connecting part 22 is arranged on the fixed limiting rod 2 through an auxiliary connecting part, and the outer connecting part 22 is used for adsorbing and fixing the outer side wall of the forming die.

[0028] Refer to Figure 2 , Figure 4 and Figure 5The inner connecting part 21 includes three mounting seats 211 that are evenly fixedly connected along the circumference of an outer wall of a fixing ring, and each mounting seat 211 is connected with a negative pressure suction cup 212 through a telescopic component 3; the outer connecting part 22 has the same structure as the inner connecting part 21, and the negative pressure suction cup 212 on the inner connecting part 21 and the negative pressure suction cup on the outer connecting part 22 are arranged alternately; a synchronous pushing group 4 is connected to the mounting plate 1 through a buffer part, and the synchronous pushing group 4 is used to synchronously push the negative pressure suction cups 212 on the inner connecting part 21 and the outer connecting part 22 to respectively press against the inner wall and outer wall of the forming mold.

[0029] It should be noted that the robot arm is an existing structure, which can drive the mounting plate 1 to move in the up, down, left and right directions, so as to facilitate the grabbing of the forming mold equipped with hexagonal bricks to the existing vibration table (not shown in the figure) for vibration demolding. The robot arm drives the mounting plate 1 and the structure under the mounting plate 1 to move to the forming mold where the hexagonal bricks have been formed. The inner connecting part 21 and the outer connecting part 22 are respectively on the inner and outer side walls of the forming mold, and the synchronous pushing group 4 is started to push the negative pressure suction cups 212 on the inner connecting part 21 and the outer connecting part 22 to negatively adsorb and fix the inner and outer side walls of the forming mold. The three negative pressure suction cups 212 on the inner connecting part 21 are on the forming mold. On the three sides of the inner wall interval of the mold, the three negative pressure suction cups 212 on the external connection part 22 are on the three sides of the outer wall interval of the molding mold, and the negative pressure suction cups 212 on the inner connection part 21 and the outer connection part 22 are staggered. The reasons for this arrangement are as follows: the line connecting the adsorption center points of the three negative pressure suction cups 212 on the inner wall forms an equilateral triangle, and the line connecting the adsorption center points of the three negative pressure suction cups 212 on the outer wall also forms an equilateral triangle. The principle of stability of the triangle is used to make the inside and outside of the molding mold stably connected, and the adsorption points of the inner and outer walls are staggered to optimize the stress distribution, so that the adsorption points are subjected to balanced force, and its stability performance is further increased.

[0030] The negative pressure suction cup 212 is an existing suction cup hanger, and a plurality of negative pressure suction cups 212 are connected to the same mechanical pump for operation (the corresponding air pipe and mechanical pump structure are not shown in the figure).

[0031] See also Figure 1 and Figure 2 The auxiliary connecting part includes a fixing ring 2 fixedly connected to the fixed limiting rod 2, and the fixing ring 2 is located above the fixing ring 1, and a connecting frame 23 is evenly fixedly connected along the circumference of the fixing ring 2. The connecting frame 23 is an inverted L-shaped structure, and the bottom ends of multiple connecting frames 23 are commonly fixedly connected with an auxiliary mounting ring 24. The three mounting seats on the external connecting part 22 are evenly fixedly connected along the circumference of the inner wall of the auxiliary mounting ring 24.

[0032] The height of the inner connecting part 21 and the outer connecting part 22 is fixed relative to the fixed limiting rod 2 through the fixing ring 1 and the auxiliary connecting part, and the horizontal heights of the inner connecting part 21 and the outer connecting part 22 are the same. The robotic arm drives the inner connecting part 21 and the outer connecting part 22 to move to the position of the molding die. When the negative pressure suction cup 212 on the inner connecting part 21 approaches the inner side wall of the molding die, correspondingly, the negative pressure suction cup of the outer connecting part 22 will approach the position of the outer side wall of the molding die. Since there is no external positioning structure, the central axis of the fixed limiting rod 2 cannot be directly aligned with the center line of the molding die, and one or both of the negative pressure suction cups 212 on the inner and outer sides will be close to the inner and outer side walls of the molding die. In the natural state of the telescopic assembly 3, the relative distance between the negative pressure suction cup 212 on the inner connecting part 21 and the negative pressure suction cup on the outer connecting part 22 on the same horizontal plane is greater than the thickness of the molding die, so as to facilitate the initial placement operation of the inner connecting part 21 and the outer connecting part 22.

[0033] Refer to Figure 4 and Figure 5 , the telescopic assembly 3 includes a limiting rod 31 fixedly connected to the mounting seat 211, a sliding block 32 slidably connected to the limiting rod 31, and a spring telescopic rod 33 fixedly connected to the other side of the sliding block 32. An inclined surface is provided at the upper end of the side of the sliding block 32 close to the limiting rod 31, and a sliding groove is provided on the side of the sliding block 32 close to the limiting rod 31. A tension spring is fixedly connected between the limiting rod 31 and the sliding groove.

[0034] It should be noted that the elastic coefficient of the spring telescopic rod 33 is much greater than that of the tension spring. When the tension spring is in the natural state, the distance between the sliding block 32 and the mounting seat 211 is the smallest. The function of the spring telescopic rod 33 is to slow down the vibration inertia force during the demolding on the vibrating table subsequently, so that the negative pressure suction cup 212 can adsorb on the molding die more stably.

[0035] Refer to Figure 1 and Figure 3 , the buffer part is used to slow down the vibration inertia force generated by the synchronous pushing group 4 during vibration. The buffer part includes an annular circular plate 51 movably penetrating through the fixed limiting rod 2, and a thickened spring 52 is fixedly connected between the mounting plate 1 and the annular circular plate 51. The thickened springs 52 are evenly distributed along the circumferential direction of the fixed limiting rod 2.

[0036] Refer to Figure 2 and Figure 3, the synchronous driving group 4 includes at least two electric telescopic rods 41 fixedly connected to the bottom end of the annular circular plate 51. The telescopic ends of multiple electric telescopic rods 41 are commonly fixedly connected with an auxiliary connection ring 42. Two pressing plates 43 are symmetrically and fixedly connected to the bottom end of the auxiliary connection ring 42. At both ends of the bottom of the pressing plate 43, a push rod 44 is fixedly connected. The bottom ends of two push rods 44 close to the fixed limiting rod 2 are commonly connected with an inner pressing part 45, and the bottom ends of two push rods 44 on the side away from the fixed limiting rod 2 are commonly connected with an outer pressing part 46.

[0037] During operation, two electric telescopic rods 41 are started simultaneously. The electric telescopic rods 41 simultaneously push the two pressing plates 43 to move downward through the auxiliary connection ring 42. The pressing plates 43 drive the inner pressing part 45 and the outer pressing part 46 to move downward through the push rods 44.

[0038] Refer to Figure 1 , Figure 3 and Figure 4 , the inner pressing part 45 includes three limiting grooves evenly opened along the outer wall circumference of the fixed limiting rod 2. The bottom ends of two push rods 44 close to the fixed limiting rod 2 are commonly fixedly connected with an inner ring plate 451. Along the inner wall circumference of the inner ring plate 451, a first raised block 452 is evenly fixedly connected. The positions of the first raised block 452 correspond to those of the limiting grooves one by one, and the first raised block 452 slides up and down in the limiting grooves. Along the outer wall circumference of the inner ring plate 451, an inner pushing rod 453 is evenly fixedly connected. The end of the inner pushing rod 453 away from the inner ring plate 451 is arc-shaped.

[0039] Refer to Figure 2 and Figure 3 , the outer pressing part 46 includes three auxiliary mounting blocks evenly fixedly connected along the upper end circumference of the auxiliary mounting ring 24. A sliding groove is opened on the side of the auxiliary mounting block close to the fixed limiting rod 2. The bottom ends of two push rods 44 on the side away from the fixed limiting rod 2 are commonly fixedly connected with an outer ring plate 461. Along the outer wall circumference of the outer ring plate 461, a second raised block 462 is evenly fixedly connected. The positions of the second raised block 462 correspond to those of the sliding grooves one by one, and the second raised block 462 slides up and down in the sliding grooves. Along the inner wall circumference of the outer ring plate 461, an outer pushing rod 463 is evenly fixedly connected. The end of the outer pushing rod 463 away from the outer ring plate 461 is arc-shaped.

[0040] The functions of the inner pressing part 45 and the outer pressing part 46 are the same. The inner ring plate 451 is limited in the limiting groove through the first raised block 452 to ensure the stability of the inner ring plate 451 during the up and down movement. Correspondingly, the outer ring plate 461 is limited in the sliding groove of the auxiliary installation block through the second raised block 462, further increasing the stability of the outer ring plate 461 during the up and down movement. The inner pushing rod 453 and the outer pushing rod 463 simultaneously press the inclined surfaces at the upper ends of the corresponding sliding blocks 32, pushing the sliding blocks 32 to drive the negative pressure suction cups 212 to move towards the corresponding side walls of the forming die. When the inner pushing rod 453 and the outer pushing rod 463 move to half of the inclined surfaces of the sliding blocks 32, when the tension spring is stretched to nearly the longest state, the spring telescopic rod 33 does not undergo elastic deformation, ensuring that the negative pressure suction cups 212 are tightly attached to the side walls of the forming die, and multiple negative pressure suction cups 212 adsorb the forming die simultaneously. The inner pushing rod 453 and the outer pushing rod 463 continue to move downward. At this time, since the distances between the multiple negative pressure suction cups 212 and the forming die are different, the spring telescopic rod 33 can also play an adaptive adjustment role here, making the center line of the forming die close to the central axis of the fixed limiting rod 2, and the stresses received by the spring telescopic rods 33 connected to the multiple negative pressure suction cups 212 are basically the same.

[0041] The forming die is adsorbed and clamped through the inner connecting part 21 and the outer connecting part 22. The robotic arm moves to the existing vibrating table for vibration demolding operation. Since the inner connecting part 21 adsorbs the inner side wall of the forming die inward and the outer connecting part 22 adsorbs the outer side wall of the forming die outward, the spring telescopic rod 33 will absorb most of the vibration force's influence on the inner connecting part 21 and the outer connecting part 22. Part of the acting force is transmitted to the synchronous pushing group 4, and the vibration force will also be effectively reduced through the energy absorption and frequency adjustment of the thickened spring 52. Correspondingly, damping rubber pads (not shown in the figure) are respectively arranged at the joints of the thickened spring 52 and the spring telescopic rod 33 with the corresponding structures to enhance the reduction of the influence caused by the vibration force. After the vibration ends, the robotic arm drives the inner connecting part 21 and the outer connecting part 22 to move the forming die up and down to facilitate better demolding of the formed hexagonal bricks. The robotic arm clamps and unlocks the formed die after demolding. The specific operation is as follows: Start the synchronous pushing group 4 to move upward and release the negative pressure adsorption of the negative pressure suction cups 212. Then move the robotic arm again to re-clamp the forming die containing the hexagonal bricks for demolding operation.

[0042] In an embodiment of the present invention, unless otherwise clearly specified or limited, the first feature being "on" or "under" the second feature may be that the first and second features are in direct contact, or the first and second features are indirectly in contact through an intermediate medium. Moreover, the first feature being "above", "over" and "on top of" the second feature may be that the first feature is directly above or obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "under", "beneath" and "underneath" the second feature may be that the first feature is directly below or obliquely below the second feature, or merely indicates that the horizontal height of the first feature is less than that of the second feature.
