Description

Technical Field

[0001] This utility model relates to the field of stamping deburring technology, and in particular to a three-way punching deburring mechanism with protective measures. Background Technology

[0002] An aluminum alloy tee is a pipe fitting used for branch connections in pipelines. Made of aluminum alloy, it is primarily used to change the direction of fluid flow. During the manufacturing process of aluminum alloy tees, the mounting holes need to be deburred to allow for connection and installation on other pipelines. Currently, deburring of aluminum alloy tees is typically done manually using files or sandpaper. Some semi-automated equipment uses pneumatic devices for deburring, such as Chinese patent CN201821419454.2, which discloses a multi-directional deburring fixture. This fixture includes a first lateral punching mechanism, a second lateral punching mechanism, and a forward punching mechanism. The first and second lateral punching mechanisms are symmetrically arranged and connected by the forward punching mechanism. Both the first and second lateral punching mechanisms include a return spring mounting post, through which a cylinder push plate is connected. The right side of the cylinder push plate is provided with a first fixing plate and a second fixing plate, respectively. The tooling only requires manual placement of the product into the positioning device for punching, but the semi-automatic coordination between manual labor and the punching equipment still poses safety hazards. Operator fatigue or violations of operating procedures in an attempt to increase production efficiency could lead to manual product positioning. Alternatively, operator error could cause the cylinder to activate during the workpiece positioning process, resulting in a safety accident. Therefore, the safety performance of this tooling needs improvement. Utility Model Content

[0003] In view of this, the present invention provides a three-way punching and deburring mechanism with protective measures to solve the above problems.

[0004] A three-way punching and deburring mechanism with protective measures includes a base plate, a positioning assembly mounted on the base plate, two punching assemblies respectively mounted on both sides of the positioning assembly, and a protective assembly mounted on one side of the punching assemblies. The two punching assemblies are arranged opposite each other and include a punching cylinder, a punching plate mounted on the output end of the punching cylinder, and at least four punches mounted on the punching plate. The protective assembly includes a frame, two manual valves mounted inside the frame, a double-pressure valve mounted on one side of the manual valves, a pneumatically controlled valve mounted on one side of the double-pressure valves, a first three-way connector mounted inside the frame, a second three-way connector mounted inside the frame, a third three-way connector mounted inside the frame, and a fourth three-way connector mounted inside the frame. The punching cylinder has two gas chambers, a working chamber and a reset chamber, respectively. The pneumatic control valve has six ports: a main air inlet, a secondary air inlet, a working port, a reset port, and two exhaust ports. The two outputs of the first three-way connector are connected via air pipes to the inputs of the second three-way connector and the secondary air inlet of the pneumatic control valve, respectively. The two outputs of the second three-way connector are connected via air pipes to the inputs of the two manual valves, and the outputs of the two manual valves are connected via air pipes to the two inputs of the dual-pressure valve. The output of the dual-pressure valve is connected via air pipes to the main air inlet of the pneumatic control valve. The working port of the pneumatic control valve is connected via air pipes to the input of the third three-way connector. The two outputs of the third three-way connector are connected via air pipes to the working chambers of the two punching cylinders, respectively. The reset port of the pneumatic control valve is connected via air pipes to the input of the fourth three-way connector, and the two outputs of the fourth three-way connector are connected via air pipes to the reset chambers of the two punching cylinders, respectively.

[0005] Furthermore, the positioning component includes a limiting plate fixedly disposed on the base plate, and two positioning blocks spaced apart on one side of the limiting plate.

[0006] Furthermore, the limiting plate has at least four punched holes.

[0007] Furthermore, the positioning block is U-shaped and fixedly mounted on the base plate, with the U-shaped opening of the positioning block facing away from the base plate, and one of the two positioning blocks is fixedly mounted on the side wall of the limiting plate.

[0010] Furthermore, the exhaust port is equipped with an exhaust venting muffler.

[0011] Compared with the prior art, the T-joint punching and deburring mechanism provided by this utility model uses two punching cylinders to drive two punching plates closer to or further away from the aluminum alloy T-joint on the positioning block, thereby using the punch to perform deburring operations on the through hole. Furthermore, due to the protective components, the two punching cylinders only start working when the operator presses both buttons simultaneously, ensuring that the operator's hands are always away from the punching area, preventing accidents and improving safety performance.

[0017] The specific embodiments of this utility model are described in further detail below. It should be understood that the description of the embodiments of this utility model herein is not intended to limit the scope of protection of this utility model.

[0018] like Figure 1 The diagram shows a structural schematic of the tee punching and deburring mechanism with protective measures provided by this utility model. The tee punching and deburring mechanism with protective measures includes a base plate 10, a positioning component 20 disposed on the base plate 10, two punching components 30 respectively disposed on both sides of the positioning component 20, and a protective component 40 disposed on one side of the punching component 30. It is conceivable that the tee punching and deburring mechanism with protective measures also includes other functional modules, such as a power module, an air pipe module, an air supply module, etc., which are technologies known to those skilled in the art and will not be described in detail here.

[0019] Please refer to the following: Figures 2 to 5 The deburring mechanism with protective measures is used to perform deburring operations on an aluminum alloy tee 50. The aluminum alloy tee 50 has at least four through holes 51 on each of its two corresponding end faces, which are used to fix the aluminum alloy tee 50 to other workpieces by screws. The deburring mechanism with protective measures is used to perform deburring operations on eight of the through holes 51.

[0020] The base plate 10 is used to support the various components so that they can cooperate in various ways to complete the deburring and punching operation on the through hole 51 on the aluminum alloy tee 50.

[0021] The positioning component 20 includes a limiting plate 21 fixedly mounted on the base plate 10, and two positioning blocks 22 spaced apart on one side of the limiting plate 21.

[0022] The limiting plate 21 has at least four punch holes 23, which correspond to the four through holes 51 on one side of the aluminum alloy tee 50, so as to cooperate with the punching assembly 30 to perform burr punching operation on the aluminum alloy tee 50. The specific cooperation will be described below.

[0023] The positioning block 22 is U-shaped and fixedly mounted on the base plate 10. The U-shaped opening of the positioning block 22 faces away from the base plate 10. One of the two positioning blocks 22 is fixedly mounted on the side wall of the limiting plate 21.

[0024] The two positioning blocks 22 are arranged at intervals, with the spacing matching the length of the aluminum alloy tee 50. The U-shaped opening of the positioning block 22 matches the width of the aluminum alloy tee 50. In this way, the aluminum alloy tee 50 can be placed on the two positioning blocks 22, and one side of the aluminum alloy tee 50 abuts against the side wall of the limiting plate 21, thereby completing the positioning function of the aluminum alloy tee 50.

[0025] The two punching assemblies 30 are arranged opposite to each other, each including a punching cylinder 31, a punching plate 32 disposed at the output end of the punching cylinder 31, and at least four punches 33 disposed on the punching plate 32.

[0026] The punching cylinder 31 has two gas chambers, a working chamber and a reset chamber, which are respectively connected to the protection component 40. The working chamber is located on the side away from the positioning component 20.

[0027] When high-pressure gas is filled into the working chamber, the punching plate 32, under the action of the high-pressure gas, drives the punch 33 to approach the positioning component 20, thereby performing a burr punching operation on the aluminum alloy tee 50 placed on the positioning component 20.

[0028] When high-pressure gas is filled into the reset chamber, the punching plate 32, under the action of the high-pressure gas, drives the punch 33 away from the positioning component 20, thereby removing the punch 33 from the through hole 51 in preparation for the next punching operation.

[0029] The two ends of the two punching plates 32 are respectively movably sleeved on the two guide posts to serve as guides during the punching operation.

[0030] The eight punches 33 correspond to the eight through holes 51 on the aluminum alloy tee 50 placed on the positioning assembly 20.

[0031] One of the two punching components 30 is located on the side of the limiting plate 21 away from the positioning block 22. The four punches 33 on it are driven by the punching cylinder 31 to pass through the four punch holes 23 respectively, so as to continue to move and pass through the four through holes 51, thereby completing the burr punching operation.

[0032] Another punching assembly 30 of the two punching assemblies 30 is located on the side of the two positioning blocks 22 away from the limiting plate 21. A rubber block 34 is fixedly mounted on the side of the punching plate 32 facing the positioning block 22 in this punching assembly 30. The cross-sectional area of ​​the rubber block 34 is larger than the cross-sectional area of ​​the U-shaped opening of the positioning block 22. One end of each of the four punches 33 passes through the rubber block 34. During the punching operation, the punching cylinder 31 drives and moves the punching plate 32 toward the aluminum alloy tee 50 placed on the positioning block 22. When the punches 33 are performing the punching operation, the outer periphery of the rubber block 34 abuts against the positioning block 22, and its inner periphery abuts against and compresses the aluminum alloy tee 50. This stabilizes the aluminum alloy tee 50 while preventing damage to it.

[0033] The protection component 40 includes a frame 41, two manual valves 42 disposed inside the frame 41, a dual-pressure valve 43 disposed on one side of the manual valves 42, a pneumatic valve 44 disposed on one side of the dual-pressure valve 43, a first tee connector 45 disposed inside the frame 41, a second tee connector 46 disposed inside the frame 41, a third tee connector 47 disposed inside the frame 41, and a fourth tee connector 48 disposed inside the frame 41.

[0034] The frame 41 has a cover plate, which is used to accommodate various valves and air pipe joints, thereby protecting them and preventing dust and debris from falling into the frame 41 and interfering with the valves.

[0035] The manual valve 42 has two push-button switches 49 protruding from the frame 41. The manual valve 42 has an input terminal and an output terminal, and the input terminal and output terminal of the manual valve 42 will only be connected when the push-button switch 49 is pressed.

[0036] The dual-pressure valve 43 is a component in a pneumatic pipeline. It has two input terminals and one output terminal. The two input terminals will only be connected to the output terminal when there is a pneumatic pressure signal at both input terminals at the same time.

[0037] The pneumatic control valve 44 has six ports: a main air inlet 441, a secondary air inlet 442, a working port 443, a reset port 444, and two exhaust ports 445. Four connector ports are connected to the aforementioned valve or tee connector to provide power to the cylinder for its punching operation.

[0038] When the main air intake 441 receives a pressure signal, it connects to the working port 443, the auxiliary air intake 442 disconnects from the reset port 444, and the reset port 444 connects to one of the exhaust ports 445. When the main air intake 441 does not receive a pressure signal, it disconnects from the working port 443, the working port 443 connects to the other exhaust port 445, and the auxiliary air intake 442 connects to the reset port 444.

[0039] The exhaust port 445 is equipped with an exhaust venting muffler, which can reduce exhaust noise.

[0040] The manual valve 42, the dual-pressure valve 43, and the pneumatic control valve 44 are existing technologies, and their internal structures and working principles will not be described in detail here.

[0041] The first, second, third, and fourth tee connectors 45, 46, 47, and 48 are all standard tee connectors, each with one input terminal and two output terminals.

[0042] The following describes the air circuit connection and working principle within the protection component 40: An external air supply module is connected to the input end of the first three-way connector 45 via an air pipe. The two output ends of the first three-way connector 45 are connected to the input end of the second three-way connector 46 and the auxiliary air inlet 442 of the pneumatic control valve 44 via air pipes, respectively. The two output ends of the second three-way connector 46 are connected to the input ends of the two manual valves 42 via air pipes, respectively. The output ends of the two manual valves 42 are connected to the two input ends of the dual-pressure valve 43 via air pipes, respectively. The output end of the dual-pressure valve 43 is connected to the main air inlet 441 of the pneumatic control valve 44 via an air pipe. The working port 443 of the pneumatic control valve 44 is connected to the input end of the third three-way connector 47 via an air pipe. The two output ends of the third three-way connector 47 are connected to the working chambers of the two punching cylinders 31 via air pipes, respectively. The reset port 444 on the pneumatic control valve 44 is connected to the input end of the fourth three-way connector 48 via an air pipe, and the two output ends on the fourth three-way connector 48 are connected to the reset chambers of the two punching cylinders 31 via air pipes.

[0043] Through the aforementioned gas connection, an external gas supply module continuously supplies gas to the first three-way connector 45. The gas is then delivered through the first three-way connector 45 to the second three-way connector 46 and the auxiliary air inlet 442 on the pneumatic control valve 44, and then through the second three-way connector 46 to the two manual valves 42.

[0044] In the initial state, the main air inlet 441 does not receive a pressure signal, the auxiliary air inlet 442 is connected to the reset port 444, and the gas enters the fourth three-way connector 48 through the reset port 444, and enters the reset chambers of the two punching cylinders 31 through the two output terminals of the fourth three-way connector 48, thereby causing the two punching cylinders 31 to drive the two punching plates 32 away from the positioning component 20.

[0045] After the operator places the aluminum alloy tee 50 on the two positioning blocks 22, the operator presses both hands on the two push-button switches 49 to activate the two manual valves 42. The input and output terminals of the two manual valves 42 are interconnected, and gas enters the two input terminals of the dual-pressure valve 43, thereby connecting the two input and output terminals of the dual-pressure valve 43. Then, the gas enters the main air inlet 441 of the pneumatic control valve 44.

[0046] The main air inlet 441 receives a pressure signal and is connected to the working port 443. The auxiliary air inlet 442 is disconnected from the reset port 444, and the reset port 444 is connected to an exhaust port 445. Gas enters the third three-way connector 47 through the working port 443 and then enters the working chambers of the two punching cylinders 31 through the two output terminals of the third three-way connector 47, thereby causing the two punching cylinders 31 to drive the two punching plates 32 closer to the positioning assembly 20 for punching operations. At this time, the gas in the reset chamber of the punching cylinder 31 is discharged from the exhaust port 445 under pressure through the reset port 444.

[0047] Compared with the prior art, the T-joint punching and deburring mechanism with protective measures provided by this utility model uses two punching cylinders 31 to drive two punching plates 32 to move closer to or further away from the aluminum alloy T-joint 50 on the positioning block 22, thereby using the punch 33 to perform deburring operations on the through hole 51. Furthermore, due to the protective component 40, the two punching cylinders 31 will only start working when the operator presses both buttons 44 simultaneously, thus ensuring that the operator's hands are always away from the punching area, avoiding safety accidents and improving safety performance.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Any modifications, equivalent substitutions or improvements within the spirit of the present utility model are covered within the scope of the claims of the present utility model.
