Description

Technical Field

[0001] The invention relates to the technical field of tube shrinking machines, and in particular to a full-automatic double-head tube shrinking machine for heat pipes used for machining motor shafts. Background Art

[0002] A heat pipe is a heat transfer element that utilizes the principle of heat conduction and the rapid heat transfer properties of phase change media. When in use, the heat from the heat source is transferred to one end of the heat pipe, and the working fluid in the pipe absorbs heat and vaporizes. The vaporized fluid flows to the other end of the heat pipe under the action of the pressure difference, and dissipates heat and condenses into liquid after encountering a cold source. The liquid fluid returns from the cold source to the heat source under the action of capillary action, and the cycle continues to achieve the purpose of rapid heat conduction.

[0003] During the manufacturing process of heat pipes, the heat pipe needs to be placed between two shrinking dies, and then the shrinking dies are driven to move by a pneumatic cylinder or a hydraulic cylinder to achieve shrinkage of the heat pipe; however, current shrinking machines are mostly manually loaded and unloaded. As the working hours increase, the staff becomes more tired, which leads to reduced loading and unloading efficiency, and after manual loading, the start button needs to be pressed to shrink the pipe, which leads to reduced production efficiency; for this reason, the present application proposes a fully automatic double-head shrinking machine for heat pipes for motor shaft processing. Summary of the invention

[0004] The purpose of the present invention is to solve the above technical problems and to propose a fully automatic double-head heat pipe shrinking machine for motor shaft processing.

[0007] A tube reduction assembly; the tube reduction assembly comprises two tube reduction die heads mounted on a processing table;

[0008] The feeding assembly can transport the heat pipes in the feeding frame one by one to between the two shrinking dies, and can drive the two shrinking dies to move relative to each other to shrink the two ends of the heat pipe. During the resetting process of the feeding assembly, the heat pipes that have been shrunk can be unloaded.

[0021] In summary, the present invention has significant beneficial effects in terms of automated production, precise tube shrinkage control, intelligent unloading mechanism and stable and reliable operation, and provides an efficient and reliable solution for the motor shaft processing industry.

DETAILED DESCRIPTION

[0028] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0029] Reference Figure 1-Figure 5 A fully automatic double-head shrinking machine for heat pipes for motor shaft processing includes a processing table 1. In order to stably support the processing table 1, four support legs 2 are fixedly connected to the bottom of the processing table 1.

A notch 10 is provided on the loading frame 8. The notch 10 is provided to place the heat pipe in the upper loading frame 8.

[0030] The tube reduction assembly; the tube reduction assembly includes two tube reduction dies 7 installed on the processing table 1, the tube reduction die heads 7 are tube reduction molds, the tube reduction assembly includes two mounting blocks 6 fixed on the processing table 1, a first piston cylinder 31 fixedly connected thereto is penetrated through the mounting block 6, a first movable piston 33 is slidably connected in the first piston cylinder 31, a driving rod 32 is fixedly connected to the first movable piston 33, the tube reduction die head 7 is fixed on the driving rod 32, the first movable piston 33 moves to drive the driving rod 32 to move, and the tube reduction die head 7 can be driven to move, the feeding assembly includes a support plate 3 fixed on the processing table 1, a hydraulic cylinder 4 is installed on the support plate 3, a moving rod 20 is fixedly connected to the output end of the hydraulic cylinder 4, a push plate 11 is slidably connected to the processing table 1, a limiting block 13 is fixedly connected to the push plate 11, the upper end of the limiting block 13 is higher than the inner bottom of the feeding frame 8, so that when the limiting block 13 abuts against the feeding frame 8, the push plate 11 can be limited.

[0031] A discharge groove 12 is provided through the front and rear ends of the upper end of the push plate 11, so that the heat pipe can be stably placed in the discharge groove 12 and is not easy to move; the width of the discharge groove 12 is smaller than the length of the heat pipe.

[0032] The moving rod 20 is connected to the push plate 11 through a pressure supply mechanism connected to the first piston cylinder 31. The pressure supply mechanism includes a second piston cylinder 14 fixed on the push plate 11. A second moving piston 19 is slidably connected in the second piston cylinder 14. A spring 17 is fixed on the second moving piston 19. The other end of the spring 17 is fixedly connected to the inner wall of the second piston cylinder 14. The moving rod 20 is fixedly connected to the second moving piston 19. The second piston cylinder 14 is connected to the first piston cylinder 31 through a delivery pipe 18.

[0033] The feeding assembly can transport the heat pipes in the feeding frame 8 one by one to between the two shrinking dies 7, and can drive the two shrinking dies 7 to move relative to each other to shrink the two ends of the heat pipe. During the resetting process of the feeding assembly, the heat pipes that have been shrunk can be unloaded.

[0034] The unloading part is explained in detail: a sleeve 23 rotatably connected to the processing table 1 is penetrated by the processing table 1, and the inside of the sleeve 23 is a rectangular groove 28, and a rectangular block 24 is slidably connected in the rectangular groove 28, and a reciprocating screw 25 is fixedly connected to the rectangular block 24, and a fixing ring 26 is fixedly connected to the processing table 1. The reciprocating screw 25 penetrates the fixing ring 26 and is connected with it, and the upper end of the reciprocating screw 25 is rotatably connected to a push rod 21, which is arranged close to the rear side of the processing table 1, and can push one end of the heat pipe upward.

[0035] The bottom of the push rod 21 is fixedly connected to two guide rods 22, which penetrate the processing table 1 and are slidably connected thereto. The bottom of the sleeve 23 is fixedly connected to a short rod 27, on which a one-way bearing 29 is mounted, on which a gear 30 is mounted. An L-shaped rod 16 is fixed to the bottom of the second piston cylinder 14, on which a rack plate 15 is fixed, which meshes with the gear 30. A through groove 5 is penetrated on the processing table 1, and the L-shaped rod 16 is arranged to penetrate the through groove 5.

[0036] When the present invention is used, the staff places the heat pipe in the loading frame 8, and the initial state of the push plate 11 is that the discharge trough 12 is directly opposite to the loading frame 8, and the heat pipe falls into the discharge trough 12 due to gravity, and the bottom of the second heat pipe on the lower side is flush with the upper end of the push plate 11, so that when the push plate 11 moves, it will not be interfered;

[0037] The hydraulic cylinder 4 drives the push plate 11 to move. Due to the setting of the spring 17, the moving rod 20 and the second piston cylinder 14 are a whole. The movement of the push plate 11 drives the heat pipe to move. When the limit block 13 abuts against the feeding frame 8, the heat pipe is opposite to the two shrinking die heads 7, so that the feeding of the heat pipe is realized;

[0038] Since the limit block 13 cannot move, the push plate 11 will not move, and the output end of the hydraulic cylinder 4 drives the moving rod 20 to move, which can drive the second moving piston 19 to move. At this time, the spring 17 is compressed, and the hydraulic oil in the second piston cylinder 14 can be delivered to the first piston cylinder 31 through the delivery pipe 18. The hydraulic oil in the first piston cylinder 31 increases and drives the first moving piston 33 to move. The movement of the first moving piston 33 drives the driving rod 32 and the tube shrinking die head 7 to move. The two tube shrinking dies 7 squeeze the two ends of the heat pipe to compress the tube.

[0039] The movement of the second piston cylinder 14 drives the L-shaped rod 16 and the rack plate 15 to move, and the rack plate 15 drives the gear 30 to rotate, and the rotation of the gear 30 drives the one-way bearing 29 to rotate. At this time, the one-way bearing 29 rotates relatively inside, that is, the gear 30 and the short rod 27 rotate relatively.

[0040] The output end of the hydraulic cylinder 4 is reset, and the second movable piston 19 is reset under the action of the spring 17, so that the hydraulic oil in the first piston cylinder 31 can be sucked into the second piston cylinder 14, so that the two shrinking die heads 7 can be separated from the heat pipe, and an electric push rod can be installed on the mounting block 6. An extrusion block is fixed to the output end of the electric push rod. The extrusion block and the heat pipe are matched with the discharge groove 12 to position the heat pipe, so as to prevent the shrinking die head 7 from separating from the heat pipe and driving the heat pipe to move. The electric push rod and the extrusion block are not shown in the figure;

[0041] Next, the hydraulic cylinder 4 drives the push plate 11 to reset. At this time, the heat pipe after shrinking is still in the discharge trough 12. The second piston cylinder 14 moves to drive the L-shaped rod 16 and the rack plate 15 to move. The rack plate 15 drives the gear 30 to rotate. The rotation of the gear 30 drives the one-way bearing 29 to rotate. At this time, the one-way bearing 29 drives the short rod 27 to rotate. The rotation of the short rod 27 drives the sleeve 23 to rotate. The rotation of the sleeve 23 drives the rectangular block 24 and the reciprocating screw 25 to rotate. Since the push rod 21 is guided by the guide rod 22, the reciprocating screw 25 can be coordinated with the fixing ring 26 when it rotates. The upward movement of the reciprocating screw 25 drives the push rod 21 to move upward, which can push one end of the heat pipe to make it tilt, and finally it is separated from the discharge trough 12 due to gravity, so as to realize the automatic unloading of the heat pipe.

[0042] Explanation of the reciprocating screw 25, that is, when the heat pipe moves to above the push rod 21, the reciprocating screw 25 is driven to rotate, the reciprocating screw 25 rotates upward and then resets, so it will not interfere with subsequent loading and other work;

[0043] Then the reciprocating screw rod 25 moves downward and resets, at which time the output end of the hydraulic cylinder 4 resets, and the discharge trough 12 is opposite to the heat pipe again, and the heat pipe falls into the discharge trough 12 due to gravity;

[0044] The hydraulic cylinder 4 works and repeats the above work, so that the heat pipe can be continuously loaded and shrunk, which reduces the involvement of manual labor and thus reduces the workload of the staff. Long-term processing can improve work efficiency and is safer during the processing.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept 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.
