Description

Technical Field

[0001] The invention relates to the technical field of auxiliary molding of prefabricated building components, in particular to an auxiliary molding device for prefabricated building components. Background Art

[0002] In the field of prefabricated buildings, hexagonal bricks are widely used in pavements and decorative components. As a kind of concrete prefabricated parts, the production quality and efficiency of hexagonal bricks directly affect the project cost and construction progress. In the traditional hexagonal brick forming process, the demoulding process has long relied on the manual rubber tire method. The specific process is: workers inject concrete into the hexagonal mold, then let it stand and cure until it is initially set, then manually lift the mold, and finally smash it hard on 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 materials factories for decades, with the demand for upgrading the construction industrialization, its technical pain points have become increasingly prominent. The specific defects are as follows: 1. Low operating efficiency: A single demoulding requires the coordinated operation of multiple workers, and workers repeat the beating action for a long time, which is easy to cause fatigue, low production capacity, and cannot match the rhythm of the automated production line. At the same time, the beating action is dangerous.

[0003] 2. Unstable demoulding success rate: relying on workers’ experience to judge the strength and angle of the impact, the brick breakage rate is high, and the hardness of the rubber tire is affected by temperature (the difference between summer and winter is as high as 15% Shore hardness), which leads to fluctuations in demoulding force.

[0004] 3. Material loss: The impact of falling causes the edges of concrete to collapse, resulting in material loss. Summary of the invention

[0011] In one possible implementation, the buffer portion is used to mitigate the vibration inertia force generated by the vibration of the synchronous push group, and the buffer portion includes: an annular circular plate that movably passes through the fixed limit rod and a thickened spring fixedly connected between the mounting plate and the annular circular plate, and the thickened spring is evenly distributed along the circumference of the fixed limit rod.

DETAILED DESCRIPTION

[0026] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of 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 violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

[0027] See also Figure 1 , Figure 2 and Figure 6 A prefabricated building component auxiliary forming device includes a mounting plate 1 fixedly connected to the execution end of a robot arm, a fixed limiting rod 2 is fixedly connected to the bottom end of the mounting plate 1, an inner connecting portion 21 is fixedly connected to the bottom end of the fixed limiting rod 2 through a fixing ring, and the inner connecting portion 21 is used to adsorb and fix the inner side wall of the forming mold; an outer connecting portion 22 is provided on the fixed limiting rod 2 through an auxiliary connecting portion, and the outer connecting portion 22 is used to adsorb and fix the outer side wall of the forming mold.

[0028] See also 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 relative to the fixed limiting rod 2 is fixed by 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 consistent. The mechanical arm drives the inner connecting part 21 and the outer connecting part 22 to move to the position of the molding mold. When the negative pressure suction cup 212 on the inner connecting part 21 is close to the inner wall of the molding mold, the negative pressure suction cup of the outer connecting part 22 will be close to the outer wall of the molding mold accordingly. 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 mold. One or two of the inner and outer negative pressure suction cups 212 will be close to the inner and outer walls of the molding mold. In the natural state of the telescopic component 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 mold, so as to facilitate the initial placement of the inner and outer connecting parts 21 and 22.

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

[0034] It should be noted that the elastic coefficient of the spring telescopic rod 33 is much larger than the elastic coefficient of the tension spring. When the tension spring is in a 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 subsequent demolding on a vibration table, so that the negative pressure suction cup 212 can be more stably adsorbed on the molding mold.

[0035] See also Figure 1 and Figure 3 The buffer part is used to reduce the vibration inertia force generated by the vibration of the synchronous push group 4. The buffer part includes an annular circular plate 51 that is movable through the fixed limit rod 2. A thickened spring 52 is fixedly connected between the mounting plate 1 and the annular circular plate 51. The thickened spring 52 is evenly distributed along the circumference of the fixed limit rod 2.

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

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

[0038] See also Figure 1 , Figure 3 and Figure 4 The inner pressing portion 45 includes three limiting grooves evenly opened along the circumference of the outer wall of the fixed limiting rod 2, and the bottom ends of the two pushing rods 44 close to the fixed limiting rod 2 are fixedly connected with an inner ring plate 451, and a protruding block 452 is evenly fixedly connected along the circumference of the inner wall of the inner ring plate 451. The protruding block 452 corresponds to the position of the limiting groove one by one, and the protruding block 452 is slidably connected to the limiting groove up and down, and an inner pushing rod 453 is evenly fixedly connected along the circumference of the outer wall of the inner ring plate 451, and the end of the inner pushing rod 453 away from the inner ring plate 451 is arc-shaped.

[0039] See also Figure 2 and Figure 3 The outer pressing portion 46 includes three auxiliary mounting blocks which are evenly fixedly connected along the circumference of the upper end of the auxiliary mounting ring 24. A sliding groove is provided on the side of the auxiliary mounting block close to the fixed limiting rod 2. The bottom ends of the two pushing rods 44 away from the fixed limiting rod 2 are commonly fixedly connected with an outer ring plate 461. A second protruding block 462 is evenly fixedly connected along the circumference of the outer wall of the outer ring plate 461. The second protruding block 462 corresponds to the position of the sliding groove one by one, and the second protruding block 462 is slidably connected to the sliding groove up and down. An outer pushing rod 463 is evenly fixedly connected along the circumference of the inner wall of the outer ring plate 461, and the end of the outer pushing rod 463 away from the outer ring plate 461 is arc-shaped.

[0040] The inner pressing portion 45 and the outer pressing portion 46 have the same function. The inner ring plate 451 is limited in the limiting groove by the protruding block 1 452 to ensure the stability of the inner ring plate 451 during the up and down movement. The corresponding outer ring plate 461 is limited in the sliding groove of the auxiliary mounting block by the protruding block 2 462 to further increase the stability of the outer ring plate 461 when it moves up and down. The inner pushing rod 453 and the outer pushing rod 463 synchronously press the inclined surface of the upper end of the corresponding sliding block 32, pushing the sliding block 32 to drive the negative pressure suction cup 212 to move toward the corresponding side wall of the forming mold, and the inner pushing rod 453 and the outer pushing rod 463 move to the sliding block 32 At the half position of the inclined surface, when the tension spring is stretched to a state close to the longest state, the spring telescopic rod 33 does not undergo elastic deformation, ensuring that the negative pressure suction cup 212 is close to the side wall of the molding mold, and multiple negative pressure suction cups 212 simultaneously adsorb the molding mold, and the inner pushing rod 453 and the outer pushing rod 463 continue to move downward. At this time, due to the different distances between the multiple negative pressure suction cups 212 and the molding mold, the spring telescopic rod 33 can also play an adaptive adjustment here, so that the center line of the molding mold and the center axis of the fixed limiting rod 2 are close to the same line, and the stresses on the spring telescopic rods 33 connected to the multiple negative pressure suction cups 212 are basically the same.

[0041] The forming mold is adsorbed and clamped by the inner connecting part 21 and the outer connecting part 22, and the mechanical arm moves to the existing vibration table for vibration demoulding. Since the inner connecting part 21 adsorbs the inner wall of the forming mold inwardly, and the outer connecting part 22 adsorbs the outer wall of the forming mold outwardly, the spring telescopic rod 33 will absorb most of the impact of the vibration force on the inner connecting part 21 and the outer connecting part 22, and part of the force is transmitted to the synchronous push group 4, and the vibration force will be effectively mitigated by the energy absorption and frequency adjustment of the thickened spring 52. Correspondingly, damping rubber pads (not shown in the figure) are respectively provided at the connection between the thickened spring 52 and the spring telescopic rod 33 and the corresponding structure to enhance the impact of mitigating the vibration force. After the vibration is over, the mechanical arm drives the inner connecting part 21 and the outer connecting part 22 to move the forming mold up and down, so as to facilitate the better demoulding of the formed hexagonal bricks. The mechanical arm clamps and unlocks the demoulding forming mold. The specific operation is: start the synchronous push group 4 to move upward, and release the negative pressure adsorption of the negative pressure suction cup 212. The robot arm is moved again to re-clamp the forming mold containing the hexagonal bricks for demoulding operation.
