Description

Technical Field

[0001] This utility model belongs to the field of composite material preform processing technology, and specifically relates to a positioning mold for a rectangular multi-ribbed preform. Background Technology

[0002] Three-dimensional textile reinforcement materials (three-dimensional textile preforms) are manufactured using a novel three-dimensional textile process technology. Continuous fiber bundles are interwoven in three-dimensional space according to certain rules to form an integral fiber network structure that runs through all directions of space. It serves as the structural reinforcement skeleton of high-performance composite materials, possessing high strength, high temperature resistance, and high damage tolerance. In particular, it allows for flexible structural design and integral molding capabilities, and is currently widely used in aerospace and other fields.

[0003] like Figure 1 As shown, after the precast material is woven and formed by textile technology, it will form a rectangular multi-ribbed precast body 10. The spacing between the various ribs 20 on the precast body 10 is different. This rectangular multi-ribbed precast body 10 usually needs to be manually trimmed to achieve the required dimensions. That is, the width of each rib 20 of the rectangular multi-ribbed precast body 10 needs to be trimmed, while ensuring that the spacing between each rib 20 meets the requirements of the design drawings. The conventional trimming method is to start from the starting position, manually use measuring tools to find the positioning points, and trim the ribs 20 one by one to meet the required size and spacing. However, this process is time-consuming, and the accuracy of manual point taking is not high, which easily produces defective products.

[0004] In view of this, the applicant conducted in-depth research on the above-mentioned issues, which led to the occurrence of this case. Summary of the Invention

[0005] The purpose of this utility model is to provide a positioning mold with a simple structure that can accurately position the ribs on the precast body to facilitate subsequent trimming.

[0006] To achieve the above objectives, this utility model adopts the following technical solution:

[0007] A positioning mold for a rectangular multi-ribbed precast structure includes a rectangular base. The upper surface of the base has a placement groove for placing the precast structure, extending along the length of the base. The base is detachably provided with several fixing blocks for securing the precast structure and several positioning plates for positioning the ribs on the precast structure. Each fixing block and each positioning plate is arranged along the length of the base. The shape of each positioning plate corresponds to the shape of the ribs of the precast structure, and the width of the positioning plate is smaller than the width of the ribs. The two ends of the positioning plate along its length are located on both sides of the base along its width. Both ends of the positioning plate along its length are detachably mounted on the base using fasteners. Scale strips are provided on the outer walls of both sides of the base along its width, arranged horizontally and extending from one end of the base along its length to the other.

[0008] Furthermore, the fastener includes a bolt and a nut that helically engages with the bolt. The base has grooves on both sides in the width direction for placing the bolt. The grooves are arranged along the length direction of the base and extend through both ends of the base in the length direction.

[0009] Furthermore, the longitudinal section of the groove is inverted T-shaped.

[0010] Furthermore, the bottom of the fixing block has a pressing part protruding towards the placement groove, and the pressing part is integrally formed with the fixing block.

[0011] Furthermore, the length of the pressing part is the same as the width of the placement groove.

[0012] Furthermore, after the fixing block is fixed on the base, there is a gap between the bottom of the fixing block and the bottom of the placement groove.

[0013] Furthermore, the fixing block is rectangular, and both ends of the fixing block in the length direction are provided with through countersunk holes. The top of the base has threaded holes on both sides in the width direction corresponding to the countersunk holes. The threaded holes are offset from the position of the sliding groove.

[0014] By adopting the aforementioned design scheme, the beneficial effects of this utility model are:

[0015] This utility model discloses a positioning mold for a rectangular multi-ribbed precast structure. The mold has a simple structure. Before use, the dimensions of multiple positioning plates are preset to match the design requirements. During use, the precast structure is fixed in the placement groove using fixing blocks. Then, the corresponding positioning plates are placed at the positions of the corresponding ribs. By observing the dimensions of the scale strips on the base, the positioning plates and bolts are accurately moved to the desired trimming position and then fixed with fasteners. This fixes the positioning plates to the base, placing them directly above the ribs. The portions of the ribs extending beyond the positioning plates in the width direction are the excess portions to be trimmed. The positioning plates are used sequentially to position the dimensions of each rib on the precast structure, facilitating subsequent trimming of the excess portions. This ensures that the trimmed ribs meet the design requirements for size and spacing, improving the pass rate of the trimmed precast structure.

[0016] Furthermore, a groove is provided for placing bolts, allowing the bolts to move within the groove, thus making it easier and faster to fix the positioning plate and effectively improving efficiency.

[0017] Furthermore, the inverted T-shaped groove can be fitted to the bolt, making it less prone to wobbling when moving within the groove, thus improving stability. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figures 1 to 5As shown, a positioning mold for a rectangular multi-ribbed precast structure is characterized by comprising a rectangular base 1, the upper surface of which is provided with a placement groove 11 for placing the precast body 10. Specifically, the placement groove 11 is located in the middle of the base 1 and extends along the length direction of the base 1. The base 1 is detachably provided with a plurality of fixing blocks 2 for fixing the precast body 10 and a plurality of positioning plates 3 for positioning the ribs 20 on the precast body 10. Each fixing block 2 and each positioning plate 3 is arranged along the length direction of the base 1. The precast body 10 is placed in the placement groove 11. When the preform 10 is placed in the groove 11, it needs to be fixed in the groove 11 to prevent it from moving. Preferably, the bottom of the fixing block 2 has a pressing part 21 protruding towards the groove 11. The pressing part 21 is integrally formed with the fixing block 2. When the thickness of the preform 10 is less than the height of the groove 11, the pressing part 21 is used to contact the preform 10, thereby pressing the preform 10 into the groove 11. Preferably, in this utility model, at least three fixing blocks 2 need to be provided. The three fixing blocks 2 are respectively provided at both ends of the preform 10 in the length direction and at the preform 10. The middle part of the body 10 can achieve a good fixing effect. In actual use, the number of fixing blocks 2 can be increased or decreased according to the length of the prefabricated body 10. Preferably, the fixing block 2 of this utility model is rectangular. The two ends of the length direction of the fixing block 2 are respectively located on both sides of the width direction of the base 1. Both ends of the length direction of the fixing block 2 are provided with through countersunk holes 22. The two sides of the top of the base 1 in the width direction are provided with threaded holes 13 corresponding to the countersunk holes 22. Preferably, the length of the pressing part 21 is the same as the width direction of the placement groove 11, which can completely hold the prefabricated body. The precast body 10 is pressed against the base. During installation, the precast body 10 is first placed in the placement groove 11, and then three fixing blocks 2 are respectively set at both ends of the length direction of the precast body 10 and the middle of the precast body 10. The fixing blocks 2 are fixed on the base 1 by passing screws through the countersunk holes 22 and locking them on the threaded holes 13 of the base 1. Thus, the precast body 10 is fixed in the placement groove 11 of the base 1. It should be noted that after the fixing blocks 2 are fixed on the base 1, there is a gap between the bottom of the pressing part 21 and the bottom of the placement groove 11. This gap is used to reserve space for placing the precast body 10.

[0033] The shape of the positioning plate 3 corresponds to the shape of the rib 20 of the precast body 10, and the width of the positioning plate 3 is smaller than the width of the rib 20. Specifically, in this utility model, the positioning plate 3 is a rectangular body, and the two ends of the positioning plate 3 in the length direction are respectively located on both sides of the width direction of the base 1. Both ends of the positioning plate 3 in the length direction are detachably mounted on the base 1 by fasteners; preferably, the fasteners include bolts 41 and nuts 42 that are screwed into the bolts 41. Correspondingly, both ends of the positioning plate 3 in the length direction are provided with through holes for the bolts 41 to pass through. Both sides of the base 1 are provided with grooves 12 for placing bolts 41. The grooves 12 are offset from the threaded holes 13. The grooves 12 are arranged along the length of the base 1 and pass through both ends of the length of the base 1. The outer walls of both sides of the base 1 in the width direction are provided with scale strips 5. The scale strips 5 are arranged horizontally and extend from one end of the length of the base 1 to the other end. The grooves 12 for placing bolts 41 are provided so that the bolts 41 can move in the grooves 12, thereby making it more convenient and faster to fix the positioning plate 3, which can effectively improve efficiency.

[0034] Preferably, the longitudinal section of the slide groove 12 is inverted T-shaped. The inverted T-shaped slide groove 12 can be adapted to the bolt 41, so that the bolt 41 is not easy to shake when it moves in the slide groove, thus improving stability.

[0035] This utility model discloses a positioning mold for a rectangular multi-ribbed precast body. The mold has a simple structure. Before use, the dimensions of multiple positioning plates 3 are preset to match the design requirements. During use, the precast body 10 is fixed in the placement groove 11 using fixing blocks 2. Then, the positions of the ribs 20 on the precast body 10 are observed. Bolts 41 are then inserted into the sliding groove 12 from any end of the base 1 along its length (with the bolt shank facing upwards). Bolts 41 are placed at the two ends of the ribs 20 to be trimmed along their length. Positioning plates 3 of the corresponding size are then placed at the corresponding positions of the ribs 20, allowing the bolts 41 to pass through the through holes in the positioning plates 3. By observing the position of the scale strip 5 on the base 1, the positioning plates 3 and bolts 41 are accurately moved to the desired trimming position. Finally, bolts 41 are tightened using nuts 42, thus fixing the positioning plates 3 to the base 1 and placing them directly above the ribs 20. The portions of the ribs 20 extending beyond the positioning plates 3 along their width are the excess portions to be trimmed (e.g., the portion extending beyond the positioning plates 3 along their width). Figure 5 As shown, the positioning plate 3 is used sequentially to position the dimensions of each rib 20 on the precast body 10 in the manner described above. This facilitates the operator to trim the excess parts of the rib 20, so that the trimmed rib 20 meets the size and spacing requirements of the design and improves the pass rate of the trimmed precast body 10.

[0036] Although embodiments of the present 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 present invention, the scope of which is defined by the appended claims and their equivalents.
