Description

Technical Field

[0001] The utility model relates to the technical field of titanium alloy cylindrical parts processing, in particular to a hot spinning forming tool for titanium alloy cylindrical parts. Background Art

[0002] Spinning is to fix a flat plate or hollow blank on the die of a spinning machine, and while the blank rotates with the spindle of the machine tool, a spinning wheel or steel rod is used to pressurize the blank to produce local plastic deformation. Spinning is a special forming method. The spinning method can be used to complete processes such as drawing, flanging, shrinking, bulging and curling of rotating bodies of various shapes. Since titanium alloy is a special metal material with light weight, high strength and good corrosion resistance, it is often used in aviation, aerospace, medical and other fields. Among them, the hardness of titanium alloy is also very high, usually between HB195 and HB300. In order to process the metal into a cylindrical part by spinning, the initial titanium alloy blank needs to be heated at high temperature first, and then repeatedly forged to make the blank cylindrical, and then cut into thinner flat plates with cutting equipment before subsequent spinning processing can be carried out.

[0003] When forging titanium alloy at high temperature, a pad with suitable curvature size is needed to place the blank. However, when processing cylindrical blanks of different diameters, the pad must be replaced with one with suitable curvature, otherwise the blank will be difficult to shape during forging. Generally, the pad is fixed on the base or directly integrated with the base, which makes it inconvenient to quickly replace the pad.

[0004] To this end, the utility model provides a hot spinning forming tool for a titanium alloy cylindrical part to solve the above-mentioned problem. Utility Model Content

[0005] 1. Technical issues to be solved

[0006] In view of the problems existing in the above-mentioned prior art, the utility model provides a hot spinning forming tool for titanium alloy cylindrical parts, which solves the above-mentioned problems.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0032] Example 1

[0033] Reference Figures 1 to 5 , is the first embodiment of the utility model, which provides a hot spinning forming tool for titanium alloy cylindrical parts, including a base 1, a quick-change component 2 is arranged inside the base 1; a locking component 3 is arranged on one side of the base 1; a forging forming component 4 is also arranged on one side of the base 1; the quick-change component 2 includes an arc pad 21, a protruding block 22 is fixedly connected to the bottom of the arc pad 21, a limiting block 23 is inserted inside the protruding block 22, the limiting block 23 is slidably connected to the inside of the base 1, a reset spring 25 is fixedly connected to one side of the limit block 23, one end of the reset spring 25 is fixedly connected to one side of the inner wall of the base 1, and a pull rod 24 is also fixedly connected to one side of the limit block 23, and the pull rod 24 passes through one side of the base 1 and is movably connected.

[0034] Specifically, the locking assembly 3 includes a mounting frame 31, which is fixedly connected to one side of the base 1. A ring reinforcement block 32 is fixedly connected to the top of the mounting frame 31. A remote-controlled electric push rod 33 is fixedly installed inside the ring reinforcement block 32. The movable end of the remote-controlled electric push rod 33 can be inserted into one end of the pull rod 24.

[0035] Furthermore, when the arc pad 21 needs to be replaced, the movable end of the remote control electric push rod 33 is first controlled to retract through the remote control to release the restriction on the pull rod 24 (using the remote control to control the remote control electric push rod 33 can improve the confidentiality and security of the operation of the equipment, and irrelevant personnel without the remote control cannot replace it), and then the pull rod 24 is pulled to drive the limit block 23 to move backward and compress the reset spring 25 to release the restriction on the protruding block 22. The arc pad 21 can then be pulled out of the base 1 and replaced with an arc pad 21 of a suitable size and reinserted (arc pads 21 of various sizes are integrated with the protruding block 22 during production, and the size of the protruding block 22 remains unchanged). When the protruding block 22 is fully inserted, the pull rod 24 can be released to release the elastic force of the reset spring 25. The limit block 23 is rebounded and inserted into the protruding block 22 so that it can completely restrict the arc pad 21, thereby completing the replacement operation and the process is simple and convenient (the limit block 23 and the pull rod 24 can be made of engineering plastics, which can be used as engineering materials and plastics to replace metals to manufacture machine parts, etc. Engineering plastics have excellent comprehensive properties, high rigidity, low creep, high mechanical strength, good heat resistance, and good electrical insulation.

[0036] Example 2

[0037] Reference Figures 1 to 5 , which is the second embodiment of the utility model, is based on the previous embodiment, and the forging forming assembly 4 includes an auxiliary block 41, a hydraulic rod 42 is fixedly installed inside the auxiliary block 41, and a docking block 43 is fixedly connected to the movable end of the hydraulic rod 42. A concave frame 44 is fixedly connected to one side of the docking block 43, and a transverse plate 412 is fixedly connected between the inner walls of the concave frame 44. The forging forming component 4 includes an assembling block 45, the top of which is fixedly connected to an upper slide bar 46, which passes through a side wall of the concave frame 44 and is movably connected, the outer wall of the upper slide bar 46 is fixedly connected to a rib 413, the top of the assembling block 45 is fixedly connected to a first spring 48, one end of the first spring 48 is fixedly connected to a side of the inner wall of the concave frame 44, the bottom of the assembling block 45 is fixedly connected to a lower slide bar 47, the lower slide bar 47 passes through a horizontal plate 412 and is movably connected, the bottom of the assembling block 45 is fixedly connected to a second spring 49, one end of the second spring 49 is fixedly connected to the top of the horizontal plate 412, and one end of the lower slide bar 47 is fixedly connected to a forging hammer 410.

[0038] Specifically, the assembly block 45 has a built-in dual-axis motor, and eccentric wheels 411 are fixedly connected to the output shafts at both ends of the dual-axis motor.

[0039] Furthermore, after the titanium alloy billet is placed on the arc pad 21, the dual-axis motor inside the assembly block 45 is started to drive the eccentric wheels 411 on both sides to rotate. After the eccentric wheels 411 rotate, the upper slide bar 46 and the lower slide bar 47 can move back and forth up and down under the cooperation of the two opposite elastic forces of the first spring 48 and the second spring 49, and then the lower slide bar 47 can drive the forging hammer 410 to hammer the billet back and forth to shape it. When the shaping is completed, the hydraulic rod 42 can be started to push the docking block 43 upward, thereby driving the concave frame 44 to move upward together, so that the forging hammer 410 is away from the billet, to prevent the dual-axis motor in the assembly block 45 from being turned off. The upper slide bar 46 and the lower slide bar 47 will continue to move for a period of time due to inertia, causing the forging hammer 410 to continue to move and cause deformation of the billet. The rib 413 can ensure that the upper slide bar 46 can only move up and down to prevent rotation during the up and down movement.

[0040] Working principle: when the arc pad 21 needs to be replaced, first use the remote control to control the movable end of the remote control electric push rod 33 to retract and release the restriction on the pull rod 24 (using the remote control to control the remote control electric push rod 33 can improve the confidentiality and security of the equipment operation, and irrelevant personnel without the remote control cannot replace it), and then pull the pull rod 24 to drive the limit block 23 to move backward and compress the reset spring 25 to release the restriction on the protruding block 22. The arc pad 21 can be pulled out of the base 1 and then replaced with a suitable size of arc pad 21 and reinserted. When the protruding block 22 is fully inserted, the pull rod 24 can be released to allow the reset spring 25 to release the elastic force to bounce the limit block 23 back and insert it into the protruding block 22 so that it completely restricts the arc pad 21, thereby completing the replacement operation and the process is simple and convenient. When the titanium alloy After the blank is placed on the arc pad 21, the double-axis motor inside the assembly block 45 is started to drive the eccentric wheels 411 on both sides to rotate. After the eccentric wheels 411 rotate, the upper slide bar 46 and the lower slide bar 47 can move back and forth up and down under the cooperation of the two opposite elastic forces of the first spring 48 and the second spring 49, and then the lower slide bar 47 can drive the forging hammer 410 to hammer the blank back and forth to shape it. When the shaping is completed, the hydraulic rod 42 can be started to push the docking block 43 upward, thereby driving the concave frame 44 to move upward together, so that the forging hammer 410 is away from the blank, to prevent the double-axis motor in the assembly block 45 from being turned off. The upper slide bar 46 and the lower slide bar 47 will move for a period of time due to inertia, causing the forging hammer 410 to continue to move and cause deformation of the blank. The rib 413 can ensure that the upper slide bar 46 can only move up and down to prevent rotation during the up and down movement.
