Description

Technical Field

[0001] The invention relates to the field of spinning fixture equipment, in particular to a spinning die fan-shaped fixture. Background Art

[0002] As an important processing and production method, spinning is widely used in product forming processing, mainly in the production of large-scale heavy industrial products, including the production of thin-walled tubular products and ring-shaped products such as tuyere products and aerospace products. During the spinning process, the workpiece needs to be clamped by a fixture and the spinning is carried out under the rotation drive of the spinning spindle.

[0003] When the existing spinning process is aimed at a specific fan-shaped mold, due to the fixed shape of the mold, the commonly used spinning fixture cannot achieve precise positioning and clamping, and usually the mold is required for auxiliary positioning. Especially when processing the blank, the blank needs to be transferred to the production line. If a general fixture is used, the production cost of the transfer line will increase, the utilization rate of the fixture is low, and the equipment cost of the fixture and the mold will increase. Moreover, due to the large size and weight of the spinning equipment, the fixture change is complicated and time-consuming, which reduces the spinning production efficiency and increases the difficulty of changing the production. Therefore, there is a need for a spinning mold fan-shaped fixture. Summary of the invention

The rotating upper mold plate 10 and the spinning mold lower mold 24 serve to limit the overall position of the first rotating mold fan-shaped clamp 13 and the second rotating mold fan-shaped clamp 14, ensuring that the first rotating mold fan-shaped clamp 13 and the second rotating mold fan-shaped clamp 14 can be stably docked and closed, increasing the stability of the clamping and line turning operations of the fan-shaped mold blank, so that the device can complete the operation more efficiently and stably.

[0035] Preferably, positioning grooves 4 are equidistantly provided on the upper surface of the positioning butt plate 3, and a pressure plate is provided at the end of the pressure rod 5, which is movably clamped and installed in the positioning groove 4. A locking nut 6 is movably bolted on the outer surface of the pressure rod 5, and the lower surface of the locking nut 6 is pressed against the upper surface of the positioning butt plate 3. The position of the pressure plate is fixed by the positioning groove 4 provided on the upper surface of the positioning butt plate 3, so that the use position of the pressure rod 5 is fixed, and the use of the pressure rod 5 is more stable by tightening the locking nut 6. At the same time, the positioning grooves 4 are equidistantly provided at the center point of the positioning butt plate 3 to ensure that the overall force on the rotating upper template 10 is the same after the pressure rod 5 is subjected to the force of the same booster component, so that the overall force on the rotating upper template 10 is more balanced, and the use angle of the single group of first rotating mold fan-shaped clamps 13 and second rotating mold fan-shaped clamps 14 will not be tilted, resulting in instability in the clamping line.

[0036] Furthermore, a slot 7 is provided downwardly at the center of the positioning plate 3, and a mold pressing plate 8 is movably installed inside the slot 7. The outer surface of the mold pressing plate 8 is tightly installed in the inner wall of the slot 7, and an inner bin 9 is provided inside the mold pressing plate 8. The slot 7 can ensure the stability of the mold pressing plate 8 to the greatest extent, so that the mold pressing plate 8 can be stably pressed and stably connected to the positioning plate 3, and the inner bin 9 provided on the top of the mold pressing plate 8 can be fixedly connected to the output end of the rotating component, and provide a rotating force for the rotating upper mold plate 10 when the rotating component is working, so as to ensure that the first rotating mold fan-shaped clamp 13 and the second rotating mold fan-shaped clamp 14 play a stable turning line role during the clamping process, such as Figure 2 shown.

[0037] Example 2

[0038] It is worth noting that three groups of limit rods 11 are equidistantly installed on the lower surface of the rotating upper template 10 with the center position of the rotating upper template 10 as the axis, the limit rods 11 include main limit rods and auxiliary limit rods, the auxiliary limit rods are located on both sides of the main limit rods, and separation rods 12 are installed at intervals between the limit rods 11 on the lower surface of the rotating upper template 10. The limit rods 11 are equidistantly installed with the center of the rotating upper template 10 as the axis, so that the installation and use positions of the first rotating mold fan-shaped clamp 13 and the second rotating mold fan-shaped clamp 14 are relatively stable, and the maximum extent is guaranteed that each group of the first rotating mold fan-shaped clamp 13 and the second rotating mold fan-shaped clamp 14 The rotating mold fan-shaped clamp 14 has a consistent working state, which increases the stability of clamping and turning lines. The limiting rod 11 includes a main limiting rod and auxiliary limiting rods on both sides, which can effectively limit the movement of the first rotating mold fan-shaped clamp 13 and the second rotating mold fan-shaped clamp 14, so that the first rotating mold fan-shaped clamp 13 and the second rotating mold fan-shaped clamp 14 can only move up and down separately, and will not cause closing instability. The installed separating rod 12 plays a limiting role to prevent the first rotating mold fan-shaped clamp 13 and the second rotating mold fan-shaped clamp 14 from colliding with the fan-shaped mold blank when clamping the fan-shaped mold blank, causing damage.

[0039] In addition, a clamping plate 15 is installed on the corresponding sides of the first rotary mold fan-shaped clamp 13 and the second rotary mold fan-shaped clamp 14, and a limiting groove 16 is provided through the position of the first rotary mold fan-shaped clamp 13 and the second rotary mold fan-shaped clamp 14 corresponding to the limiting rod 11. Three groups of the first rotary mold fan-shaped clamp 13 and the second rotary mold fan-shaped clamp 14 corresponding to the limiting rod 11 are provided. After a group of the first rotary mold fan-shaped clamp 13 and the second rotary mold fan-shaped clamp 14 completes the clamping and fixing operation, they rotate to clamp the next group of the first rotary mold fan-shaped clamp 13 and the first rotary mold fan-shaped clamp 13. The material holding operation, at the same time, the previous group of clamping operations completes the line transfer operation after rotation, so that the first rotary mold fan-shaped clamp 13 and the second rotary mold fan-shaped clamp 14 work in a cycle, and the line transfer operation is completed while clamping to improve production efficiency. The clamping plate 15 is set to limit and clamp the mold blank, so that the first rotary mold fan-shaped clamp 13 and the second rotary mold fan-shaped clamp 14 can limit the fan-shaped mold blank more stably after closing. The stability of the first rotary mold fan-shaped clamp 13 and the second rotary mold fan-shaped clamp 14 is increased by setting a limiting groove 16 in conjunction with the limiting rod 11, such as Figure 3 , 4 and 5.

[0040] Example 3

[0041] Furthermore, the spinning demoulding ejector rod 18 is fitted on the upper surface of the spinning demoulding device 17, and the lower surface of the spinning demoulding device 17 is equidistantly bolted with a macro base upper mast 25 with the center of the spinning demoulding device 17 as the axis. A limited placement inner groove 19 is provided downwardly from the center of the upper surface of the spinning demoulding ejector rod 18, and a limited bottom groove 20 is provided upwardly from the center of the lower surface of the spinning demoulding ejector rod 18. The spinning demoulding device 17 has installation grooves extending upwardly and downwardly corresponding to the limited bottom groove 20. The use position of the spinning demoulding ejector rod 18 is ensured by arranging the spinning demoulding device 17, and the macro base upper mast 25 installed at the bottom of the spinning demoulding device 17 increases the connectivity of the spinning demoulding device 17, so that the device as a whole can be fixed more stably, and the spinning demoulding The mounting groove provided through the center of the device 17 allows the output end of the height-increasing component to extend into and connect with the bottom end of the center positioning rod 22. The rotation component drives the center positioning rod 22 to move inside the positioning sleeve rod 21, so that the positioning sleeve rod 21 can be stably raised and lowered, thereby controlling the height adjustment of the lower mold 24 of the spinning mold, so that the limiting groove 16 is raised, thereby releasing or clamping the mold blank. The limiting bottom groove 20 allows the positioning sleeve rod 21 and the center positioning rod 22 to have better moving space, and at the same time provides a stable position for the connection between the center positioning rod 22 and the height-increasing component. The spinning demoulding ejector rod 18 serves the purpose of limiting the lower mold 24 of the spinning mold, thereby limiting the position of clamping the mold blank and making the device more stable and efficient to use.

[0042] Furthermore, through holes are opened through the centers of the limiting bottom groove 20 and the limiting placement inner groove 19, and a lower die seat 23 is arranged at the bottom of the lower die 24 of the spinning mold. The outer surface of the lower die seat 23 is movably installed in contact with the inner wall of the limiting placement inner groove 19. The through hole makes the use and movement of the positioning sleeve 21 more stable, and the through hole effectively limits the positioning sleeve 21. The limiting placement inner groove 19 is opened so that the lower die seat 23 can be completely received in the limiting placement inner groove 19, thereby increasing the overall stability of the device, so that the lower surface of the lower die 24 of the spinning mold can be completely in contact with the upper surface of the spinning demolding ejector pin 18, and the lower die 24 of the spinning mold is limited.

[0043] Preferably, a positioning sleeve rod 21 is provided at the bottom of the lower die seat 23, and the positioning sleeve rod 21 is movably installed through the through hole. A center positioning rod 22 is provided inside the positioning sleeve rod 21, and the center positioning rod 22 can move inside the positioning sleeve rod 21, thereby controlling the lifting and lowering of the positioning sleeve rod 21 to rotate the upper mold plate 10 and the lower mold 24 of the spinning mold to press against the limit groove 16 to lift and lower, complete the clamping operation, and realize the purpose of clamping and taking materials, rotating and turning lines. Figure 6 , 7 and 8.

[0044] In addition, the limiting rod 11 includes two parts: a fixed rod 26 and a movable rod 31, wherein the bottom of the fixed rod 26 is provided with an inner groove 27, a connecting spring 28 is installed inside the inner groove 27, the bottom end of the connecting spring 28 is fixedly connected to a connecting block 29, the connecting block 29 is slidably installed inside the inner groove 27, and a threaded rod 30 is fixedly installed on the top of the movable rod 31, the threaded rod 30 is movably bolted inside the connecting block 29, and the threaded rod 30 is rotated into the connecting block 29 by rotating the movable rod 31 to perform a movable connection, and the ductility of the upper and lower separation of the first rotating mold fan-shaped clamp 13 and the second rotating mold fan-shaped clamp 14 is increased by the connecting spring 28, so as to better adapt to different fan-shaped materials, and the inner groove 27 limits the use of the connecting spring 28 and the connecting block 29, such as Fig. 9 and 10 shown.

[0045] An inner rotating rod 101 is rotatably installed at the center position of the rotating upper template 10, one end of the inner rotating rod 101 is protruding outward and is provided with an outer convex cavity 102, the outer wall of the outer convex cavity 102 is evenly installed with rotating blades 104, the inner wall of the rotating blade 104 is integrally installed with a flexible capsule 103, one end of the flexible capsule 103 is provided with a telescopic portion 1031, the interior of the upper template 10 has a partition, and one side of the partition is penetrated by the inner rotating rod 101, a rotating rod 107 is installed at one end of the inner rotating rod 101, one side of the rotating rod 107 is fixed with an elastic portion 108 by welding, one end of the elastic portion 108 is connected with a contact ball 109, the inner wall of the upper template 10 is provided with a flexible membrane 110, the flexible membrane 110 is in contact with the contact ball 109, the inner wall of the upper template 10 is interspersed with a liquid guide tube 106, and a one-way valve 105 is provided on the liquid guide tube 106 The inner rotating rod 101 is connected to an external torque, and by driving the inner rotating rod 101 to rotate, the rotating blade 104 will be driven to rotate, and the internal space can be cooled. Due to the setting of the flexible bag 103, the contact area between the rotating blade 104 and the air can be increased. When the rotation speed is fast, the air circulation speed can be increased. When the rotation speed is slow, the rotation speed of the rotating rod 107 is reduced. Due to the effect of inertia, the contact ball 109 can be contracted inward, so that less liquid is squeezed into the telescopic part 1031, so that the volume of the flexible bag 103 is reduced, the contact area with the air is reduced, and the cooling effect is reduced, so that the heat dissipation efficiency is changed according to the speed of transporting the gas. The cooling liquid is restricted in its flow direction by the one-way valve 105, so that it can only flow in a specified direction to avoid flow turbulence.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
