Description
Technical Field
[0001] This utility model relates to the field of pipe processing technology, and in particular to a U-shaped tee pipe opening device. Background Technology
[0002] In refrigeration systems, U-shaped tees (such as U-shaped manifolds and U-shaped bypass pipes) are widely used for fluid diversion, merging, or reversal. These pipe components not only need to ensure efficient and smooth fluid flow but also need to meet the system's requirements for sealing, durability, and ease of installation. The design of U-shaped tees makes them play a key role in complex piping layouts, especially when it is necessary to change the flow direction or connect pipes of different diameters.
[0003] Traditionally, the openings of U-shaped tee copper pipes are usually made by manual cutting or stamping. This method, due to its reliance on manual operation, is prone to large dimensional errors, leading to problems such as misalignment and poor sealing during actual installation. These problems directly affect the efficiency of fluid transportation and the overall performance of the system. In addition, the uncertainty brought about by human factors increases the workload of subsequent adjustments and corrections, reduces construction efficiency, and may cause safety hazards. Therefore, we propose a U-shaped tee copper pipe opening device to solve the above problems. Utility Model Content
[0004] To overcome the shortcomings of the prior art, a U-shaped tee pipe opening device is provided.
[0005] The technical implementation scheme of this utility model is as follows: A U-shaped tee pipe opening device includes a frame and a support plate. The frame is the assembly carrier of this device. A support plate is fixedly installed on the top of the frame. The support plate is an "L"-shaped plate. The protruding plate of the support plate has a limiting groove for adapting to and limiting the material of the tee pipe. An opening for the tee pipe material to pass through the limiting groove is provided. It also includes a fixed plate, an electric push rod one, a push plate, an electric push rod two, a knife holder, a cutter, a material rack, a mounting plate, a hydraulic cylinder, and a top rod. A fixed plate is fixedly connected to the top of the support plate. An electric push rod one is horizontally fixedly installed on the top of the frame. The electric push rod one is fixedly connected to the push plate through a connecting plate. The push plate is located between the support plate and the fixed plate. The push plate is slidably limited on the support plate. A bracket is vertically fixedly installed on the top side of the machine frame away from the push plate. An electric push rod two is fixedly installed on the top of the bracket. The piston rod of the electric push rod two faces downward and is fixedly connected to a cutter holder. A cutter is assembled at the bottom of the cutter holder through a slot. The cutter slides against the protruding plate surface where the opening is located on the support plate. A material rack for placing the material to be opened into the tee pipe is provided on the fixed plate. The bottom outlet of the material rack passes through the fixed plate and leads to the top surface of the support plate. An mounting plate is fixedly connected to the side of the machine frame away from the fixed plate. A hydraulic cylinder is fixedly installed on the mounting plate. The piston rod of the hydraulic cylinder faces the support plate and is fixedly connected to a push rod. The push rod is aligned with and adapted to the opening on the support plate. A discharge device is provided on the top of the machine frame. The discharge device is used to discharge the material of the tee pipe that has been opened on the support plate.
[0006] In one embodiment, the material rack is an arc-shaped hollow frame, which is composed of multiple hollow frames adapted to the shape of T-shaped pipe materials. The material rack is used to stack and place T-shaped pipe materials, and to sequentially guide the stacked T-shaped pipe materials onto the support plate.
[0007] In one embodiment, a brush plate is fixedly installed on one side of the support plate. The brush plate is located above the support plate and there is a certain gap between the brush plate and the support plate. The bottom surface of the brush plate is provided with bristles, which contact the surface of the support plate. The bristles on the brush plate are used to clean the dust on the surface of the material passing through the T-shaped pipe, so as to avoid the dust affecting the flatness of the subsequent cutting opening of the T-shaped pipe material.
[0008] In one embodiment, the discharge component includes an electric push rod three and a pusher plate. The electric push rod three is fixedly installed longitudinally on the frame, and the pusher plate is fixedly installed on the piston rod of the electric push rod three. The pusher plate faces the front side of the frame and is used to push the open tee tube material.
[0009] In one embodiment, the frame is provided with a discharge trough in the opposite direction from the pusher plate. The discharge trough of the frame is inclined downward and is used to slide out the T-tube material pushed out by the pusher plate, so that the user can collect the T-tube material after the opening with a container at the bottom of the discharge trough.
[0010] In one embodiment, the frame has a downwardly inclined guide trough near the cutter, and a waste box is installed on the lower part of the frame near the mounting plate. The bottom outlet of the guide trough leads to the waste box, which is used to collect waste and debris cut from the T-shaped pipe.

Detailed Implementation
[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] A U-shaped tee pipe opening device, such as Figures 1-4 As shown, the device includes a frame 1 and a support plate 2. The frame 1 serves as the assembly carrier for this device. The support plate 2 is fixedly installed on the top of the frame 1. The support plate 2 is an "L"-shaped plate. The protruding plate of the support plate 2 contains a limiting groove 21 that adapts to and limits the T-shaped pipe material 100. An opening is provided at the limiting groove 21 of the support plate 2 for the T-shaped pipe material 100 to pass through when cutting the pipe body. The device also includes a fixed plate 3, an electric push rod 4, a push plate 5, an electric push rod 6, a knife holder 7, a cutter 8, a material rack 9, a mounting plate 14, a hydraulic cylinder 15, and a push rod 151. The fixed plate 3 is fixedly connected to the top of the support plate 2. An electric push rod 4 is horizontally fixedly installed on the top of the frame 1. The electric push rod 4 is fixedly connected to the push plate 5 through a connecting plate 41. The push plate 5 is located between the support plate 2 and the fixed plate 3. The push plate 5 is slidably limited on the support plate 2. The top of the frame 1 is away from the push plate. A bracket 61 is vertically fixed on one side of the frame 5. An electric push rod 6 is fixedly installed on the top of the bracket 61. The piston rod of the electric push rod 6 faces downward and is fixedly connected to a knife holder 7. A cutter 8 is assembled at the bottom of the knife holder 7 through a slot. The cutter 8 slides against the protruding plate surface where the opening is located on the support plate 2. A material rack 9 is provided on the fixed plate 3 for placing the material 100 of the three-way pipe to be opened. The bottom outlet of the material rack 9 passes through the fixed plate 3 and leads to the top surface of the support plate 2. An installation plate 14 is fixedly connected on the side of the frame 1 away from the fixed plate 3. A hydraulic cylinder 15 is fixedly installed on the installation plate 14. The piston rod of the hydraulic cylinder 15 faces the support plate 2 and is fixedly connected to a push rod 151. The push rod 151 is aligned with and adapted to the opening on the support plate 2. A discharge part is provided on the top of the frame 1. The discharge part is used to discharge the material 100 of the three-way pipe that has been opened on the support plate 2.
[0022] The material 100 of the T-shaped pipe to be opened is guided onto the support plate 2 by the material rack 9. First, the electric push rod 4 is activated to drive the connecting plate 41 and the push plate 5 to move, so that the push plate 5 pushes the T-shaped pipe material 100 onto the support plate 2 and slides into the limiting groove 21. The pipe body of the T-shaped pipe material 100 to be opened will be exposed from the opening of the support plate 2. Then, the electric push rod 4 drives the push plate 5 to reset and prepare to push the next T-shaped pipe material 100. Then, the electric push rod 6 is activated to activate the cutter 8 on the cutter holder 7. The cutting opening of the T-tube material 100 is quickly completed downwards. After the electric push rod 26 drives the cutter 8 to reset upwards, the hydraulic cylinder 15 is immediately activated. The hydraulic cylinder 15 drives the push rod 151 to push out towards the opening of the support plate 2, pushing the T-tube material 100 with the opening on the support plate 2 out of the limiting groove 21 to the discharge part. Finally, the discharge part pushes the open T-tube material 100 out of the support plate 2 and completes the discharge operation, thus completing the opening processing of a T-tube material 100.
[0023] like Figure 1 and Figure 3 As shown, the material rack 9 is an arc-shaped hollow frame. The material rack 9 is composed of multiple hollow frames that are adapted to the shape of the three-way pipe material 100. The material rack 9 is used to push and place the three-way pipe material 100, and to guide the multiple pushed three-way pipe materials 100 onto the support plate 2 in sequence.
[0024] like Figure 1 and Figure 2 As shown, a brush plate 10 is fixedly installed on one side of the support plate 2. The brush plate 10 is located above the support plate 2, and there is a certain gap between the brush plate 10 and the support plate 2. The bottom surface of the brush plate 10 is provided with bristles 11, which contact the plate surface of the support plate 2. The bristles 11 on the brush plate 10 are used to clean the dust on the surface of the T-shaped pipe material 100, so as to avoid the dust affecting the flatness of the subsequent cutting opening of the T-shaped pipe material 100, and to obtain a more accurate and smooth cutting edge of the T-shaped pipe material 100.
[0025] like Figure 2 As shown, the discharge component includes an electric push rod 12 and a pusher plate 13. The electric push rod 12 is fixedly installed longitudinally on the frame 1. The pusher plate 13 is fixedly installed on the piston rod of the electric push rod 12. The pusher plate 13 faces the front side of the frame 1 and is used to push the three-way pipe material 100 with the opening.
[0026] like Figure 3 As shown, a discharge trough 16 is provided on the frame 1 in the opposite direction from the pusher plate 13. The discharge trough 16 of the frame 1 is inclined downward and is used to slide out the three-way pipe material 100 pushed out by the pusher plate 13, so that the user can collect the three-way pipe material 100 after the opening with a container at the bottom of the discharge trough 16.
[0027] like Figure 3As shown, the frame 1 has an inclined downward guide trough 17 near the cutter 8, and a waste box 18 is installed on the lower part of the frame 1 near the mounting plate 14. The bottom outlet of the guide trough 17 leads to the waste box 18, which is used to collect the waste and debris cut off by the three-way pipe material 100.
[0028] When using this opening device to open the T-shaped pipe material 100, before operation, the T-shaped pipe material 100 to be processed is stacked in the arc-shaped hollow frame of the material rack 9. The T-shaped pipe material 100 automatically falls into the top surface of the support plate 2 through the bottom outlet. When the device is started to open the T-shaped pipe material 100, the electric push rod 4 drives the push plate 5 to move laterally, pushing the T-shaped pipe material 100 along the support plate 2 into the limiting groove 21. During the process, the bristles 11 on the bottom surface of the brush plate 10 simultaneously clean the dust on the surface of the T-shaped pipe material 100 to ensure the subsequent cutting accuracy. When the T-shaped pipe material 100 reaches the end of the limiting groove 21, the pipe body of the T-shaped pipe material 100 to be opened extends out from the opening of the support plate 2. Then, the electric push rod 4 resets, the push plate 5 returns to the initial position to prepare to push the next material, and at the same time, the electric push rod 6 starts. The three-way pipe material 100 drives the knife holder 7 and drives the cutter 8 to cut vertically downwards. The cutter 8 quickly cuts the pipe body along the edge of the support plate 2 opening. The cut waste slides into the waste box 18 through the guide groove 17 for centralized collection. After the cutting is completed, the electric push rod 6 activates the cutter 8 on the knife holder 7 to reset upwards. Then, the hydraulic cylinder 15 immediately pushes the push rod 151 through the support plate 2 opening, pushing the three-way pipe after opening out from the limiting groove 21 to the discharge position. Finally, the electric push rod 12 drives the pusher plate 13 to longitudinally push the finished three-way pipe material 100 with opening, so that the finished three-way pipe material 100 slides down the inclined discharge groove 16 into the external collection container. The whole process realizes cyclic operation through timing control. The continuous feeding of the material rack 9 and the intermittent pushing of the pusher plate 5 cooperate to ensure efficient opening processing of the three-way pipe material 100.
[0029] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. All equivalent substitutions made within the principles of this utility model should be included within the protection scope of this utility model. Contents not described in detail in this utility model are existing technologies known to those skilled in the art.
