[0030] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention. The present invention will be described in detail below with reference to the accompanying drawings.

[0031] A crimping die adaptable to composite insulation posts of various sizes, such as Figures 1 to 6 As shown, it includes an upper mold component and a lower mold component. The lower mold component includes a lower mold pressure plate 1, a fixing component, and an adjusting component. The fixing component is installed on one end of the lower mold pressure plate 1, and the adjusting component is movably disposed on the other end of the lower mold pressure plate 1. The fixing component and the adjusting component are arranged opposite each other. The composite insulating support column 100 is positioned between the fixing component and the adjusting component. The adjusting component is used to adjust the distance between the fixing component and the adjusting component. A row of spaced limiting grooves 2 are provided on the lower mold pressure plate 1, and a locking component for positioning the adjusting component is detachably installed on one of the limiting grooves 2. The upper mold component includes an upper mold pressure plate 3, which cooperates with the lower mold pressure plate 1 to press the two ends of the composite insulating support column 100.

[0032] Specifically, in use, the upper mold plate 3 and the lower mold plate 1 are opened, and the distance between the adjusting component and the fixed component is adjusted by the movable adjusting component. After adjustment, the adjusting component is aligned with its corresponding limiting groove 2. The position of the adjusting component is locked by installing a locking component on the limiting groove 2. Then, the composite insulating support is placed between the fixed component and the adjusting component. One end of the composite insulating support is fixed by the fixing component, and the other end of the composite insulating support 100 is fixed by the adjusting component. The upper mold plate 3 and the lower mold plate 1 are locked to achieve the positioning and pressing of the composite insulating support. Then, the pressing mold of this embodiment is placed in an external pressing device for pressing. The present invention has a novel structure. By adjusting the distance between the adjusting component and the fixed component, it can adapt to composite insulating supports of different lengths and sizes, improve the flexibility and versatility of use, solve the technical problem of needing multiple sizes of pressing molds for composite insulating supports of different sizes, reduce the cost pressure of enterprises that previously needed to process multiple sizes of pressing molds, and at the same time, reduce mold change time, which is conducive to improving production efficiency and thus reducing production costs.

[0033] In this embodiment, prior to the improvement, the applicant needed seven sets of crimping dies to crimp seven different lengths of semi-finished pillars. For each pillar length produced, the corresponding crimping die needed to be found, and then a forklift and other auxiliary equipment were used to install and replace the die on the crimping machine. The total cost of the crimping dies was high, at 20,000 yuan per set, for a total price of 140,000 yuan. Die-changing time was also long, approximately 40 minutes per change, with a total time of approximately 280 minutes for changing seven sets of dies, including disassembly and replacement. The lengths of the seven products were: 191, 254, 279, 356, 457, 559, and 762 mm.

[0034] In this embodiment, the improved pressing mold can press seven different lengths of column semi-finished products. Simply fixing the adjusting component to different limiting grooves 2 with the locking component allows for the pressing of column semi-finished products of varying lengths. The price of this flat pressing mold capable of pressing seven different lengths of column semi-finished products is 30,000 yuan, a 78.5% reduction compared to the total cost of 140,000 yuan for seven sets of pressing molds before the improvement. The module switching time for the seven products is reduced by approximately 56 minutes, an 80% reduction compared to the previous method.

[0035] In this embodiment, the fixing component includes a fixing base 4, a positioning drive 5, and a positioning block 6. The fixing base 4 and the positioning drive 5 are respectively mounted on one end of the lower molding plate 1. The positioning drive 5 is used to drive the positioning block 6 to move closer to or away from the fixing base 4, and the positioning block 6 is used to position the fitting 200 at one end of the composite insulating support 100. Specifically, the front end face of the positioning block 6 is provided with first positioning pins 7 on both sides for positioning the fitting 200 at one end of the composite insulating support 100. The adjustment assembly includes an adjustment seat 8, an adjustment drive 9, and an adjustment block 10. The adjustment drive 9 and the adjustment seat 8 are respectively mounted on the other end of the lower molding plate 1. The adjustment seat 8 is slidably disposed on the lower molding plate 1 and is used to position the hardware at the other end of the composite insulation post. The adjustment drive 9 is used to drive the adjustment block 10 to move back and forth. When it is necessary to adjust and reduce the distance between the fixing assembly and the adjustment assembly, the adjustment drive 9 drives the adjustment block 10 to push the adjustment seat 8 to move. The front end face of the adjustment block 10 is provided with second positioning pins 11 on both sides for positioning the hardware at the other end of the composite insulation post. Both the fixing drive and the adjustment drive 9 are cylinders.

[0036] Specifically, when the adjustment component is in operation, the position of the adjustment seat 8 can be manually slid. When it is necessary to adjust and reduce the distance between the fixing component and the adjustment component, the adjustment block 10 can be moved forward by the adjustment drive component 9 to push against the hardware at the other end of the composite insulation support, thereby moving the adjustment seat 8. A locking groove 12 is provided on one side of the adjustment seat 8, which corresponds to the limiting groove 2. The locking component includes a locking screw 13 and a locking block 14. The two ends of the locking block 14 are respectively engaged in the locking groove 12 and the limiting groove 2. When the adjustment is adjusted... After the section seat 8 and the lower mold plate 1 are positioned, the locking screw 13 is used to lock the locking block 14 to position the adjusting seat 8. Then, the two ends of the composite insulating column are placed on the fixed seat 4 and the adjusting seat 8 respectively. The positioning drive 5 drives the positioning block 6 to approach the hardware at one end of the composite insulating column, and the hardware at one end of the composite insulating column is inserted and positioned by the first positioning pin 7. The adjusting drive 9 drives the adjusting block 10 to approach the hardware at the other end of the composite insulating column, and the hardware at the other end of the composite insulating column is inserted and positioned by the two second positioning pins 11 of the adjusting block 10.

[0037] In this embodiment, a first pressing block assembly is provided on the fixing base 4, and the hardware at one end of the composite insulating post is placed on the first pressing block assembly; a second pressing block assembly is provided at one end of the lower end face of the upper mold plate 3, and the first pressing block assembly and the second pressing block assembly are arranged facing each other. The first pressing block assembly includes two parallel first pressing block bodies 15, and the upper end face of the two first pressing block bodies 15 on the side closest to each other is provided with a first arc-shaped concave surface 16, forming a first semi-circular positioning groove 17; the second pressing block assembly includes two parallel second pressing block bodies 18, and the upper end face of the two second pressing block bodies 18 on the side closest to each other is provided with a second arc-shaped concave surface 19, forming a second semi-circular positioning groove; the first semi-circular positioning groove 17 and the second semi-circular positioning groove are arranged facing each other and are used to accommodate the hardware at one end of the composite insulating post.

[0038] In this embodiment, a third pressure block assembly is provided on the adjusting seat 8, and the fitting at the other end of the composite insulating support is placed on the third pressure block assembly; a fourth pressure block assembly is detachably installed on the other end of the lower end face of the upper mold plate 3, and the third pressure block assembly and the fourth pressure block assembly are arranged facing each other, with the position of the fourth pressure block assembly adjusted according to the position of the third pressure block assembly. The third pressure block assembly includes two parallel third pressure block bodies 20, with a third arc-shaped concave surface 21 on the upper end face of the side of the two third pressure block bodies 20 that are close to each other, forming a third semi-circular positioning groove; the fourth pressure block assembly includes two parallel fourth pressure block bodies 22, with a fourth arc-shaped concave surface 23 on the upper end face of the side of the two fourth pressure block bodies 22 that are close to each other, forming a fourth semi-circular positioning groove; the third semi-circular positioning groove and the fourth semi-circular positioning groove are arranged facing each other and cooperate to accommodate and clamp the fitting at the other end of the composite insulating support.

[0039] Specifically, under the above configuration, the fittings at both ends of the composite insulating post are pressed and positioned by the cooperation of the first pressing block assembly and the second pressing block assembly, as well as the cooperation of the third pressing block assembly and the fourth pressing block assembly. That is, the outer periphery of the fittings at both ends of the composite insulating post is pressed by four pressing blocks. In other words, when the pressing mold of this application embodiment is in the pressing equipment, the pressing equipment drives the upper mold component and the lower mold component to close the mold to press the composite insulating post and the fittings at both ends.

[0040] Furthermore, in this embodiment of the application, heat dissipation grooves 24 are provided in the first arc-shaped concave surface 16, the second arc-shaped concave surface 19, the third arc-shaped concave surface 21 and the fourth arc-shaped concave surface 23. The heat dissipation grooves 24 facilitate the improvement of heat dissipation space during pressing and can reduce the impact of thermal effects.

[0041] Furthermore, the first semi-circular positioning groove 17 and the second semi-circular positioning groove form a first positioning groove. The upper ends of the inner walls of the first semi-circular positioning groove 17 are respectively provided with a first oblique cutting surface, and the lower ends of the inner walls of the second semi-circular positioning groove are respectively provided with a second oblique cutting surface. The first oblique cutting surface and the second oblique cutting surface are respectively tangent to the first positioning groove.

[0042] The third semicircular positioning groove and the fourth semicircular positioning groove form a second positioning groove. The upper ends of the inner walls of the third semicircular positioning groove are respectively provided with third oblique surfaces, and the lower ends of the inner walls of the fourth semicircular positioning groove are respectively provided with fourth oblique surfaces. The third oblique surfaces and the second oblique surfaces are tangent to the fourth positioning groove. This ensures a smooth transition between the oblique surfaces and the outer circumference of the fitting, ensuring that the contact between the fitting and the pressure block assembly is a cylindrical surface contact, reducing single-point pressure. The oblique surface design makes the contact between the composite insulating support and the fitting more uniform, achieving uniform force during pressing, while reducing the direct pressure of the mold on the composite insulating support and the fitting, reducing damage.

[0043] Of course, the upper ends of the inner walls of the first semicircular positioning groove 17 are respectively provided with a first rounded corner 25, the lower ends of the inner walls of the second semicircular positioning groove are respectively provided with a second rounded corner, the lower ends of the inner walls of the third semicircular positioning groove are respectively provided with a third rounded corner, and the lower ends of the inner walls of the fourth semicircular positioning groove are respectively provided with a fourth rounded corner.

[0044] In this embodiment, the lower die plate 1 has multiple mounting and positioning slots 26 spaced apart in a row on both sides. Specifically, the crimping die in this embodiment is used to crimp composite insulating supports and fittings in a crimping device. Since the crimping device's die slot is fixed, by moving the crimping die and selecting different mounting and positioning slots 26, the midpoint of the semi-finished composite insulating support is positioned at the center of the crimping device. The different mounting and positioning slots 26 on the crimping die ensure that the midpoint of the semi-finished composite insulating supports of different lengths is positioned at the center of the crimping device, thus balancing the force on the crimping die during crimping.

[0045] In this embodiment, the spacing between the adjusting component and the fixing component is adjusted to accommodate composite insulating posts of different lengths, thereby achieving length tolerance control and angle tolerance control, improving the stability and reliability of positioning the composite insulating posts, solving the technical problem of needing multiple sizes of crimping molds for composite insulating posts of different sizes, and improving the accuracy and stability of crimping.

[0046] In this embodiment, the lower mold plate 1 and the upper mold plate 3 are detachably connected. When not in use, the lower mold plate 1 and the upper mold plate 3 are assembled and connected by connecting rod 27 and bolt 28 to avoid scattering and facilitate storage and future use. When in use, simply remove connecting rod 27 and bolt 28 to place the pressing mold of this embodiment in the pressing equipment for use, making it flexible in use.

[0047] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some changes or modifications to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
