Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0018] Example Please see Figures 1-6 This utility model provides a tube stranding mold locking clamp, including a support transverse adjustment mechanism 10 and a mold locking assembly 20.

[0019] The support transverse adjustment mechanism 10 is used to support and transversely adjust the mold locking assembly 20, which is capable of quickly assembling and disassembling different molds.

[0020] The mold locking assembly 20 is installed on top of the support transverse adjustment mechanism 10. The mold locking assembly 20 includes a lower support 210, a top cover plate 220, a hinge part 240, and a pin part 250. One side of the lower support 210 is hinged to the top cover plate 220 via the hinge part 240. The other side of the lower support 210 is provided with an ear plate 270. The other side of the top cover plate 220 is provided with an inner edge plate 230 that, when closed, is located below the ear plate 270. The top cover plate 220, the inner edge plate 230, and the ear plate 270 are all provided with coaxial mounting holes of the same size. The pin part 250 can be detachably inserted into the mounting hole. The top of the lower support 210 and the bottom of the top cover plate 220 are both provided with positioning grooves 260 that cooperate with the mold.

[0021] The mold is placed between the lower support 210 and the top cover plate 220. The positioning groove 260 between the lower support 210 and the top cover plate 220 engages with the existing positioning block of the mold for positioning. When the top cover plate 220 covers the lower support 210 around the hinge 240, it rotates and flips inward along the plate 230 to below the ear plate 270. Then, the pin 250 is inserted into the mounting hole to complete the fixation, achieving quick mold installation. When it is necessary to replace the mold between the lower support 210 and the top cover plate 220, the pin 250 is pulled out from the mounting hole, the top cover plate 220 is flipped over to remove the internal mold, and another set of molds is replaced for fixing. Compared with the traditional method of disassembling and fixing with multiple sets of bolts, this pipe stranding mold locking fixture can achieve quick mold disassembly and replacement.

[0022] In the above specific embodiment, the pin part 250 includes a tube 251, a pin 253, a pull ring 254, and a limiting ring 255. The limiting ring 255 is located at the top of the tube 251, a groove 252 is provided on the side of the lower section of the tube 251, and the interior of the lower section of the tube 251 is provided with a frustum-shaped limiting groove 256 structure. The pull ring 254 is fixed to the top of the pin 253, and the pin 253 is inserted into the interior of the tube 251.

[0023] The tube 251 below the limiting ring 255 is pre-inserted into the mounting hole. The pin 253 is inserted into the tube 251 through the pull ring 254. The area at the lower groove 252 of the tube 251 expands outward and presses against the inner wall of the mounting hole through the cooperation of the limiting groove 256, so that the pin part 250 can be stably fixedly connected to the lower support 210 and the top cover plate 220 after being inserted into the mounting hole. Pulling the pull ring 254 upward will pull out the pull ring 254 and the pin 253 together. Then, the tube 251, which is integrated with the limiting ring 255, can be removed, which will open the top cover plate 220 above the lower support 210.

[0024] Specifically, the upper section of the inner tube 251 is provided with a groove, and a magnet 257 that magnetically engages with the pin 253 is installed inside the groove. The magnet 257 can magnetically attract the pin 253 inserted into the inner tube 251 and apply a certain force to the pin 253 radially. When the clamp as a whole is vibrated, the pin 253 is not easy to fall out of the tube 251.

[0025] Furthermore, the outer surface of the tube 251 is provided with anti-slip texture. The anti-slip texture is provided to increase the friction between the outer surface of the tube 251 and the inner wall of the mounting hole, so that the tube 251 is not easily dislodged from the mounting hole due to vibration.

[0026] In its specific configuration, the support transverse adjustment mechanism 10 includes a bracket 110, a base 120, a lead screw 130, and a handwheel 140. The base 120 is slidably mounted on top of the bracket 110, and the lead screw 130 is rotatably mounted inside the bracket 110 and screwed through to the base 120. The handwheel 140 is mounted on one end of the lead screw 130. Both sides of the base 120 have blocks that slidably engage with the bracket 110. Rotating the handwheel 140 causes the lead screw 130 to rotate, thereby moving the base 120 and the lead screw 130, which in turn causes the mold locking assembly 20 above the base 120 to shift, adjusting the distance between the mold and the equipment.

[0027] In a specific configuration, the hinge portion 240 includes a shaft 241, a first connecting seat 242, and a second connecting seat 243. The first connecting seat 242 is fixedly connected to the lower support 210, and the second connecting seat 243 is fixedly connected to the top cover plate 220. The shaft 241 rotatably passes through the first connecting seat 242 and the second connecting seat 243. The mounting holes include a first through hole 221 on the top cover plate 220, a third through hole 271 on the ear plate 270, and a second through hole 231 on the inner edge plate 230. The tube 251 in the pin portion 250 is inserted through the first through hole 221, the second through hole 231, and the third through hole 271.

[0028] The working principle of this pipe stranding mold locking fixture is as follows: During use, the mold is placed between the lower support 210 and the top cover plate 220. The positioning groove 260 between the lower support 210 and the top cover plate 220 engages with the existing positioning block of the mold for positioning. When the top cover plate 220 covers the lower support 210 around the hinge 240, it rotates and flips inward along the plate 230 to below the ear plate 270. Then, the pin 250 is inserted into the mounting hole to complete the fixation, achieving rapid mold installation. When it is necessary to replace the mold between the lower support 210 and the top cover plate 220, the pin 250 is pulled out from the mounting hole, the top cover plate 220 is flipped over to remove the internal mold, and another set of molds is then replaced for fixing. Compared to the traditional method of disassembling and fixing with multiple sets of bolts, this pipe stranding mold locking fixture enables rapid mold disassembly and replacement.

[0029] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
