Description

Technical Field

[0001] The utility model relates to the technical field of hot pressing molding, in particular to a rotary hot pressing device. Background Art

[0002] Rotary hot pressing equipment is an advanced processing equipment. Its main working principle is to place the pre-heated material in the mold, and then form the desired part shape by rotating the mold and applying pressure. Rotation ensures that the material is evenly distributed in the mold, while pressure ensures that the material is fully cured or formed under high temperature conditions.

[0003] During the rotary hot pressing process, the semi-finished product needs to be placed on a cylindrical mold and extruded multiple times at different angles until the semi-finished product is formed. After the thermosetting is completed, the formed product is tightly connected to the cylindrical mold after multiple extrusions, making it difficult to disassemble. The formed product cannot be unloaded in time, and the semi-finished product cannot be loaded in time, resulting in low working efficiency of the rotary hot pressing equipment. Utility Model Content

[0031] Please refer to Figure 1 、 Figure 2 and Figure 3 , to solve the problem of low working efficiency of the rotary hot pressing device 1000, the present utility model proposes a rotary hot pressing device 1000, including:

[0032] A frame 1, a fixing mechanism and a clamping mechanism, wherein the fixing mechanism comprises a telescopic core shaft 21, a telescopic rod 22, a cable nozzle 23 and a nozzle sleeve 24, the telescopic core shaft 21 is rotatably arranged on the frame 1, the telescopic rod 22 is movably connected to the telescopic core shaft 21, the cable nozzle 23 is arranged at the end of the telescopic rod 22 away from the telescopic core shaft 21, and the nozzle sleeve 24 is arranged on the telescopic core shaft 21; the cable nozzle 23 comprises a plurality of nozzle arms 231, the nozzle sleeve 24 is connected to one end of the telescopic core shaft 21, and is sleeved on the outer periphery of each nozzle arm 231; the inner cavity of the nozzle sleeve 24 gradually shrinks from the end away from the telescopic core shaft 21 to the end close to the telescopic core shaft 21; the clamping mechanism comprises a clamping drive 31 and a plurality of clamping claws, the clamping drive 31 is arranged on the frame 1, each clamping claw is transmission-connected to the output end of the clamping drive 31, and the clamping drive 31 drives each clamping claw to simultaneously approach or move away from a straight line extending along the axis of the telescopic core shaft 21.

[0033] In the technical solution of the present utility model, the telescopic rod 22 is extended away from the telescopic core shaft 21. At this time, the cable nozzle 23 is located at a position where the inner diameter of the inner cavity of the nozzle sleeve 24 is smaller. Due to the limitation of the inner cavity of the nozzle sleeve 24, the nozzle arms 231 of the cable nozzle 23 are closed, which is convenient for the semi-finished product to be sleeved on the cable nozzle 23; after the semi-finished product is sleeved on the cable nozzle 23, the telescopic rod 22 is retracted to a position close to the telescopic core shaft 21. At this time, the cable nozzle 23 moves to a position where the inner diameter of the inner cavity of the nozzle sleeve 24 is larger, and each nozzle arm 231 returns to the open state due to its own elastic force, so that each nozzle arm 231 is separated from each other, so that the outer periphery of each nozzle arm 231 can The semi-finished product is supported; at this time, the clamping drive 31 drives the jaws to approach each other to extrude the semi-finished product, and the jaws move away from each other after each extrusion is completed, and the telescopic core shaft 21 rotates to adjust the semi-finished product to another angle, and then the next extrusion is carried out, and this is repeated many times to extrude the semi-finished product into shape; after molding, the telescopic rod 22 extends away from the telescopic core shaft 21, so that the nozzle arms 231 of the cable nozzle 23 are closed, so that the connection between the extruded product and the cable nozzle 23 is relatively loose, and the user can easily remove the molded product from the cable nozzle 23, so that the finished product can be unloaded in time, thereby improving the working efficiency of the rotary hot pressing equipment 1000.

[0034] It is understandable that the cable nozzle 23 includes at least two nozzle arms 231. In one embodiment, the cable nozzle 23 includes three nozzle arms 231. When supporting the semi-finished product, the support structure formed by the three nozzle arms 231 is more stable than that of two nozzle arms 231, and the production cost of the three nozzle arms 231 is lower. Considering comprehensively, it is preferred that the cable nozzle 23 includes three nozzle arms 231.

[0035] Similarly, the clamping mechanism includes at least two jaws. In one embodiment, the clamping mechanism includes three jaws, and the three jaws are evenly spaced around the outer periphery of the semi-finished product. The odd number of jaws can prevent the semi-finished product from being simultaneously subjected to two opposite forces, which may cause excessive extrusion of the semi-finished product. Similarly, when the clamping mechanism includes three jaws, the production cost is lower. Therefore, it is preferred that the clamping mechanism includes three jaws.

[0036] The movement of each jaw closer to or farther from the straight line extending along the axis of the telescopic mandrel 21 can be achieved by rotation or sliding. In one embodiment, the jaw includes a slider 321 and a clamping block 322. The slider 321 is drivingly connected to the output end of the clamping driving member 31, and the clamping block 322 is provided at one end of the slider 321 away from the clamping driving member 31. The clamping mechanism further includes a guiding device corresponding to each jaw. The guiding device includes a guiding slide rail 331, and the guiding slide rail 331 is provided on the frame 1. Each slider 321 is slidably connected to a guiding slide rail 331. Each jaw slides closer to or farther from the straight line extending along the axis of the telescopic mandrel 21. In this way, the degree of extrusion of the clamping block 322 on the semi-finished product can be controlled by controlling the sliding distance of the slider 321, making the process of forming the semi-finished product more controllable, thereby improving the qualification rate of the formed product. Therefore, it is preferred to use the sliding method to move each jaw closer to the straight line extending along the axis of the telescopic mandrel 21.

[0037] In one embodiment, a clamping arc surface 3221 is formed on one side of each clamping block 322 facing the nozzle 23. Since the products formed by rotary hot pressing are generally tubular, forming the clamping arc surface 3221 on each clamping block 322 can make the clamping arc surface 3221 closely fit the outer peripheral surface of the semi-finished product, ensuring that the force on the outer periphery of the semi-finished product is more uniform during extrusion, thereby improving the qualification rate of the formed product.

[0038] Please refer to Figure 4 , in one embodiment, the clamping mechanism further includes a rotating cam plate 34. The rotating cam plate 34 has a plurality of guiding grooves 341, and the rotating cam plate 34 is drivingly connected to the clamping driving member 31. The guiding grooves 341 extend along the outer periphery of the rotating cam plate 34 towards the center of the rotating cam plate 34. The guiding device further includes a connecting arm 333, and the connecting arm 333 is rotatably connected to the slider 321. One end of the connecting arm 333 away from the slider 321 is slidably limited to the groove wall of the guiding groove 341. Thus, when the rotating cam plate 34 rotates, the connecting arm 333 slides in the guiding groove 341, driving the slider 321 to slide on the guiding slide rail 331, so that each clamping block 322 moves closer to or farther from the straight line extending along the axis of the telescopic mandrel 21.

[0039] In one embodiment, the guide device further includes a guide wheel 332, which is rotatably connected to one end of the connecting arm 333 away from the slider 321, and the guide wheel 332 is slidably limited to the groove wall of the guide groove 341. The friction between the guide wheel 332 and the guide groove 341 is rolling friction, and compared with the sliding friction of the connecting arm 333 directly sliding in the guide groove 341, the friction resistance between the guide wheel 332 and the guide groove 341 is smaller, so the use of the guide wheel 332 to assist the movement of the connecting arm 333 can make the movement of the clamping jaw smoother.

[0040] In one embodiment, the rotary hot pressing device 1000 further includes a rotary mechanism, which includes a rotary drive member 42 and a spinning hollow core shaft 41. The rotary drive member 42 is disposed on the frame 1, and the telescopic core shaft 21 is transmission-connected to the output end of the rotary drive member 42. By rotating the spinning hollow core shaft 41 with the rotary drive member 42, the spinning hollow core shaft 41 can be controlled to rotate at the same angle each time, so that the semi-finished product is extruded uniformly at various angles, which can effectively improve the qualified rate of the formed product.

[0041] In one embodiment, the fixing mechanism further includes a telescopic driving member 25, and the rotating mechanism further includes a spinning hollow shaft 41. The telescopic driving member 25 is disposed on the frame 1, and the telescopic rod 22 is transmission-connected to the output end of the telescopic driving member 25, so that the telescopic rod 22 can be telescopic relative to the telescopic core shaft 21; the spinning hollow shaft 41 is transmission-connected to the output end of the rotating driving member 42, and the telescopic core shaft 21 is connected to the spinning hollow shaft 41. The rotating driving member 42 rotates the spinning hollow shaft 41 to drive the telescopic core shaft 21 to rotate, so that the telescopic core shaft 21 will not affect the telescopic extension of the telescopic core shaft 21 when rotating.

[0042] Since the telescopic drive member 25 needs to be arranged on the axis of the telescopic core shaft 21, and since the spinning hollow core shaft 41 is arranged concentrically with the telescopic core shaft 21, the telescopic drive member 25 is also located on the axis of the telescopic core shaft 21, which will affect the installation of the rotating drive member 42. To solve this problem, please refer to Figure 5 In one embodiment, the rotating mechanism further includes a transmission belt 43 and a transmission wheel, the transmission belt 43 is transmission-connected to the output end of the rotating driving member 42, the transmission wheel is transmission-connected to the transmission belt 43, and the transmission wheel is sleeved on the spinning hollow core shaft 41. The spinning hollow core shaft 41 is transmission-connected to the output end of the rotating driving member 42 by the transmission belt 43 and the transmission wheel, so that the output end of the rotating driving member 42 can deviate from the axis of the telescopic core shaft 21, so that the rotating driving member 42 and the telescopic driving member 25 are staggered, so that the installation positions of the rotating driving member 42 and the telescopic driving member 25 do not interfere with each other, which is convenient for installation.

[0043] In one embodiment, the rotating mechanism further includes a rotating bearing and a supporting bearing, wherein the rotating bearing is provided on the frame 1 and sleeved on the spinning hollow shaft 41; the spinning hollow shaft 41 is sleeved on the supporting bearing, and the supporting bearing is sleeved on the telescopic mandrel 21. The rotating bearing is provided on the frame 1 so that the spinning hollow shaft 41 can rotate relative to the frame 1; the supporting bearing is sleeved between the spinning hollow shaft 41 and the telescopic mandrel 21 so that the telescopic mandrel 21 can rotate with the spinning hollow shaft 41 and can telescopically move relative to the spinning hollow shaft 41.

[0044] In one embodiment, the clamping mechanism further includes a transmission gear 35 and a connecting gear 36. The transmission gear 35 is disposed on the rotating cam plate 34. The connecting gear 36 is transmission-connected to the output end of the clamping driver 31. The connecting gear 36 is transmission-connected to the transmission gear 35. The clamping driver 31 is connected to the rotating cam plate 34 through gear transmission, so that the telescopic mandrel 21 can be avoided to avoid interfering with the telescopic movement of the telescopic rod 22. At the same time, the transmission gear 35 and the connecting gear 36 are installed in the interlayer space between the frame 1 and the rotating cam plate 34, so that the structure of the rotary hot pressing device 1000 is more compact.

[0045] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
