Description

Technical Field

[0001] This utility model relates to the field of automotive air conditioning pipe processing technology, and in particular to a safe and stable special punching device for automotive air conditioning pipes. Background Technology

[0002] When processing automotive air conditioning pipes, it is often necessary to punch various holes in the pipes. Existing punching devices can only punch one pipe at a time, resulting in low work efficiency. Therefore, in view of the above situation, there is an urgent need to develop a safe and stable dedicated punching device for automotive air conditioning pipes that can fix and punch multiple air conditioning pipes at once, with higher work efficiency, in order to overcome the shortcomings of current practical applications and meet current needs. Utility Model Content

[0003] The purpose of this invention is to provide a safe and stable punching device for automotive air conditioning pipes to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A safe and stable punching device for automotive air conditioning pipes includes a worktable, columns, support rods, a punching mechanism, and a clamping and fixing mechanism. The columns are fixed to the worktable. Multiple support rods are evenly distributed and fixed to the columns, supporting the air conditioning pipes. The punching mechanism includes hydraulic cylinders, a disc, and punching dies. Multiple hydraulic cylinders are fixed to the upper end of the worktable, with their telescopic ends fixed to the disc. Multiple punching dies are fixed to the lower side of the disc. Each support rod has a through hole for the punching die to pass through. The clamping and fixing mechanism is mounted on the worktable and clamps the air conditioning pipes. The clamping and fixing mechanism includes a high-pressure bidirectional air pump, an annular pipe, a connecting pipe, a solenoid valve, and an expansion clamping mechanism. The high-pressure bidirectional air pump is fixed to the worktable and connected to the annular pipe via the connecting pipe. A solenoid valve is installed on the connecting pipe. Each support rod has an expansion clamping mechanism at both ends, and each expansion clamping mechanism is connected to the annular pipe.

[0005] Preferably, the expansion clamping mechanism includes: a rigid support ring and an expansion airbag. There are two rigid support rings, which are fixed on the worktable. An expansion airbag is fixed inside each rigid support ring. The two expansion airbags surround the support rod inside. The expansion airbags are fixed and connected to the annular tube through air pipes.

[0006] Preferably, the rear end of the support rod is fixed with a positioning baffle.

[0007] Preferably, the workbench is provided with multiple waste discharge troughs, the waste discharge troughs are located below the through holes, and a waste box is placed on the ground below the waste discharge troughs.

[0008] The beneficial effects of this utility model are as follows: This safe and stable automotive air conditioning pipe punching device allows for the following steps: Multiple air conditioning pipes are inserted onto multiple support rods. Then, the solenoid valve is opened, activating the high-pressure bidirectional air pump to inflate the annular pipe and the expansion airbag. This causes the expansion airbag to inflate and clamp the air conditioning pipes onto the support rods from the outside. The solenoid valve is then closed to stabilize the air pressure inside the expansion airbag, and the high-pressure bidirectional air pump is shut off. Next, a hydraulic cylinder drives the disc and punching die to move downwards, allowing multiple punching dies to simultaneously punch multiple air conditioning pipes. The waste material generated during punching falls from the waste discharge trough into the waste box. After punching is complete, the air conditioning pipes are released using the clamping and fixing mechanism, and then the air conditioning pipes can be removed from the support rods. In summary, this utility model can fix and punch multiple air conditioning pipes at once, resulting in higher work efficiency. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0017] Specific implementation examples are given below.

[0018] See Figures 1-6 In this embodiment of the utility model, a safe and stable punching device for automotive air conditioning pipes includes a workbench 1, a column 2, support rods 3, a punching mechanism 4, and a clamping and fixing mechanism 5. The column 2 is fixed on the workbench 1. Multiple support rods 3 are evenly distributed and fixed on the column 2. The support rods 3 support the air conditioning pipes, and their outer diameter matches the inner diameter of the air conditioning pipes. The punching mechanism 4 includes a hydraulic cylinder 401, a disc 402, and a punching die 403. The hydraulic cylinder 401... Multiple hydraulic cylinders 401 are fixed to the upper end of the workbench 1. The telescopic end of the hydraulic cylinder 401 is fixed to the disc 402. Multiple punching dies 403 are fixed to the lower side of the disc 402. Each support rod 3 is provided with a through hole 301 for the punching die 403 to pass through. The clamping and fixing mechanism 5 is installed on the workbench 1 and is used to clamp the air conditioning pipe. The clamping and fixing mechanism 5 includes: a high-pressure bidirectional air pump 501, an annular pipe 502, a connecting pipe 503, a solenoid valve 504, and an expansion clamping mechanism 505. A high-pressure bidirectional air pump 501 is fixed on the workbench 1. The high-pressure bidirectional air pump 501 can both inflate and deflate. The high-pressure bidirectional air pump 501 is fixed to an annular pipe 502 via a connecting pipe 503. A solenoid valve 504 is installed on the connecting pipe 503. Each support rod 3 has an expansion clamping mechanism 505 at both ends, and each expansion clamping mechanism 505 is connected to the annular pipe 502. Each expansion clamping mechanism 505 includes a rigid support ring 5051 and an expansion air bladder 5052. Two rigid support rings 5051 are fixed on the workbench 1. Each rigid support ring 5051 has an inflatable airbag 5052 fixed inside. The two inflatable airbags 5052 surround the support rod 3 inside. The inflatable airbags 5052 are fixed and connected to the annular tube 502 through air pipes. When in use, the solenoid valve 504 is opened and the high-pressure bidirectional air pump 501 is started to inflate the annular tube 502 and the inflatable airbags 5052, so that the inflatable airbags 5052 expand and clamp the air conditioning pipe to the support rod 3 from the outside.

[0019] The rear end of the support rod 3 is fixed with a positioning baffle 302, which limits the position of the air conditioning pipe after it is inserted into the support rod 3.

[0020] The workbench 1 is equipped with a hydraulic station 7, and the hydraulic cylinder 401 is connected to the hydraulic station 7 through an oil supply pipe. The hydraulic station 7 is used to supply hydraulic oil to the hydraulic cylinder 401 to drive its operation.

[0021] The workbench 1 is provided with a plurality of waste discharge troughs 101, which are located below the through hole 301. Waste generated during punching falls from the waste discharge troughs 101. A waste box 6 is placed on the ground below the waste discharge troughs 101 to catch the waste.

[0022] A PLC controller 8 is installed on the side of the workbench 1. The high-pressure bidirectional air pump 501, solenoid valve 504 and hydraulic station 7 are all controlled by the PLC controller 8.

[0023] Working principle: This safe and stable automotive air conditioning pipe punching device works by inserting multiple air conditioning pipes onto multiple support rods 3, opening the solenoid valve 504, and starting the high-pressure bidirectional air pump 501 to inflate the annular pipe 502 and the expansion airbag 5052. This causes the expansion airbag 5052 to inflate and clamp the air conditioning pipes onto the support rods 3 from the outside. Then, the solenoid valve 504 is closed to maintain stable air pressure in the expansion airbag 5052, and the high-pressure bidirectional air pump 501 is turned off. Next, the hydraulic cylinder 401 drives the disc 402 and the punching die 403 to move down, allowing multiple punching dies 403 to punch multiple air conditioning pipes simultaneously. The waste generated from punching falls from the waste discharge trough 101 into the waste box 6. After punching is completed, the air conditioning pipes are released by the clamping and fixing mechanism 5, and then the air conditioning pipes on the support rods 3 can be removed.

[0024] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
