Description

Technical Field

[0001] This utility model relates to the field of tee manufacturing, and in particular to a punching device for producing extended tee fittings. Background Technology

[0002] Tee production is a process of manufacturing pipe fittings, which are usually "T" or "Y" shaped and have three openings (ports) to connect three pipes, enabling the diversion or merging of fluids (liquids or gases).

[0003] Existing technologies, such as the utility model patent with publication number CN211191613U, disclose a novel three-way punching machine. This patent employs a machine housing and a feeding device, a conveying device, and a punching device fixedly installed on top of the machine housing. The feeding device includes a cylindrical material placement ramp, a feeding ramp, a feeding motor, and a cylindrical material fixing position. The feeding motor drives a feeding rotating shaft connected to it. Multiple cylindrical materials are placed and installed above the cylindrical material placement ramp, and the multiple cylindrical materials are fed one by one to the top of the cylindrical material fixing position through the feeding rotating shaft. The punching device includes a punching die and two punching high-pressure cylinders. The punching die includes an upper die and a lower die. A horizontally arranged cylindrical material positioning through hole is formed in the middle of the lower die for the cylindrical material to be inserted with a gap fit. Two separate and downward-facing first punches are fixedly installed below the upper die, and a second punch is provided on the front side of the lower die. One punching high-pressure cylinder drives the upper die to move up and down, and the other punching high-pressure cylinder drives the second punches to move back and forth. The conveying device drives the cylindrical material to enter and exit the punching die.

[0004] The inventors discovered the following problems in the use of the tee punching equipment during their daily work: the positions of the mandrel and baffle in the existing tee punching equipment are fixed, and punching can only be performed at the positions near the two ends of the tube. It is not suitable for tubes of various lengths, cannot meet various punching needs, and has low adjustment flexibility. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies where the positions of the baffle and mandrel are fixed, making them unsuitable for punching operations of tubes of various lengths.

[0006] To solve the above-mentioned technical problems, this utility model provides a punching device for producing extended tees, comprising: a machine body, an adjusting structure, and an auxiliary structure. A punching device is mounted on the surface of the machine body, and a mold is fixedly connected to the inner wall of the machine body. A mandrel is mounted on the surface of the machine body via the auxiliary structure, and a tube is slidably connected to the surface of the mandrel. An adjusting structure is provided on the surface of the machine body corresponding to the position of the mandrel. The adjusting structure includes a support frame, which is fixedly connected to the machine body. An adjusting rod is rotatably connected to the inner wall of the support frame. The side of the machine body away from the tube is fixedly connected to... The device includes a servo motor, the output end of which is fixedly connected to an adjusting rod. A movable frame is threadedly connected to the arc surface of the adjusting rod. A fixed frame is slidably connected to the side of the movable frame away from the adjusting rod. The fixed frame is fixedly connected to the machine body. A limit rod is threadedly connected to the side of the movable frame away from the tube body. A clamping plate is rotatably connected to the end of the limit rod near the movable frame. Two sliding rods are fixedly connected to the side of the clamping plate near the limit rod. The arc surface of the sliding rod is slidably connected to the movable frame. A baffle is slidably connected to the inner wall of the movable frame. The baffle is slidably connected to the arc surface of the mandrel.

[0007] The aforementioned components achieve the following effect: providing an adjustment mechanism for precisely positioning the punching position of a tube body. The adjustment rod is driven to rotate by a servo motor, which in turn moves the moving frame and baffle along the mandrel axis to set the distance between the baffle and the punching position. This mechanism is suitable for processing tube bodies of various lengths and punching positions.

[0008] Preferably, the surface of the support frame is provided with a scale.

[0009] The effect achieved by the above components is that the scale provides an intuitive positioning reference, making it easier for the operator to accurately set the position of the baffle and improve positioning accuracy.

[0010] Preferably, a protective cover is fixedly connected to one side of the machine body at the position corresponding to the servo motor, and the surface of the protective cover has a number of heat dissipation holes.

[0011] The above components achieve the following effects: the protective cover protects the servo motor from external impacts and dust contamination, and the heat dissipation holes ensure effective heat dissipation of the motor, thereby improving its service life.

[0012] Preferably, the inner wall of the movable frame is slidably connected to a base plate, and the base plate is slidably connected to the surface of the mandrel.

[0013] The effect achieved by the above components is to provide further support for the mandrel using the base plate. The base plate that is compatible with the mandrel needs to be placed in the moving frame before the mandrel installation operation.

[0014] Preferably, the surface of the machine body is provided with an auxiliary structure, the auxiliary structure including two auxiliary frames, the two auxiliary frames being fixedly connected to the machine body, a bidirectional screw being rotatably connected to the inner wall of the auxiliary frame, two auxiliary plates being threadedly connected to the arc surface of the bidirectional screw, the two auxiliary plates being slidably connected to the inner wall of the auxiliary frame, and a round rod being fixedly connected to the inner wall of the auxiliary frame, the arc surface of the round rod being slidably connected to the auxiliary plates.

[0015] The above components achieve the following effects: by operating the bidirectional screw, the mandrel is clamped and fixed using the auxiliary plate, and the auxiliary structure allows for easy assembly and disassembly of the mandrel from the machine body. This makes it convenient for users to replace the mandrel with a suitable one according to the inner diameter of the tube to be processed, thereby improving the efficiency of subsequent maintenance work.

[0016] Preferably, anti-slip pads are fixedly connected to the sides of the two auxiliary plates that are close to each other, and the anti-slip pads are rubber pads.

[0017] The effect achieved by the above components is to increase friction through the anti-slip pad, ensuring that the mandrel is firmly clamped and preventing it from loosening during processing.

[0018] Preferably, one end of the bidirectional screw is fixedly connected to a disc, and a handle is slidably connected to the inner wall of the disc.

[0019] The effect achieved by the above components is that the lever can be inserted into the disc, and the double-acting screw can be easily rotated using the lever principle to achieve the clamping or loosening operation of the mandrel, saving time and effort.

[0020] Compared with related technologies, the punching equipment for producing extended tees provided by this utility model has the following beneficial effects:

[0021] By setting an adjustment structure, an adjustment mechanism is provided for precisely positioning the punching position of the tube body. The adjustment rod is driven to rotate by a servo motor, which drives the moving frame and baffle to move along the mandrel axis to set the distance between the baffle and the punching position of the mold. This allows users to accurately punch the tube body at a specified position. It is suitable for tube processing operations of various lengths and punching positions. The replaceable baffle can adapt to different tube diameters. The clamping plate driven by the limit rod can quickly clamp or release the baffle. The sliding rod ensures stable movement of the clamping plate, making it highly practical.

[0022] By setting up an auxiliary structure and operating a bidirectional screw, the mandrel is clamped and fixed using an auxiliary plate. The auxiliary structure allows for easy assembly and disassembly of the mandrel from the machine body, making it convenient for users to replace the mandrel with a suitable one according to the inner diameter of the tube to be processed, thus improving the efficiency of subsequent maintenance work.

It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0031] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0032] Please see Figures 1 to 6 The present invention provides a punching device for producing extended tees, comprising: a body 1, an adjustment structure 6 and an auxiliary structure 7. A punching device 2 is installed on the surface of the body 1, a mold 3 is fixedly connected to the inner wall of the body 1, a mandrel 4 is installed on the surface of the body 1 with the aid of the auxiliary structure 7, a tube 5 is slidably connected to the surface of the mandrel 4, an adjustment structure 6 is provided on the surface of the body 1 corresponding to the position of the mandrel 4, and an auxiliary structure 7 is provided on the surface of the body 1.

[0033] In the embodiments of this utility model, please refer to Figures 1 to 5The adjustment structure 6 includes a support frame 601, which is fixedly connected to the body 1. An adjustment rod 602 is rotatably connected to the inner wall of the support frame 601. A servo motor 603 is fixedly connected to the side of the body 1 away from the tube 5. The output end of the servo motor 603 is fixedly connected to the adjustment rod 602. A movable frame 606 is threadedly connected to the arc surface of the adjustment rod 602. A fixed frame 607 is slidably connected to the side of the movable frame 606 away from the adjustment rod 602. The fixed frame 607 is fixedly connected to the body 1. A limiting rod 608 is threadedly connected to the side of the movable frame 606 away from the tube body 5. A clamping plate 609 is rotatably connected to the end of the limiting rod 608 near the movable frame 606. Two sliding rods 610 are fixedly connected to the side of the clamping plate 609 near the limiting rod 608. The arc surface of the sliding rod 610 is slidably connected to the movable frame 606. A baffle 611 is slidably connected to the inner wall of the movable frame 606. The baffle 611 is slidably connected to the arc surface of the mandrel 4. This provides an adjustment mechanism for accurately positioning the punching position of the tube body 5. The servo motor 603 drives the adjusting rod 602 to rotate, which in turn moves the moving frame 606 and the baffle 611 along the axis of the mandrel 4 to set the distance between the baffle 611 and the punching position. This is suitable for processing tubes 5 of various lengths and punching positions. The support frame 601 has a scale 604 on its surface, which provides an intuitive positioning reference, making it easy for the operator to accurately set the position of the baffle 611 and improve positioning accuracy. A protective cover 605 is fixedly connected to one side of the machine body 1 at the position corresponding to the servo motor 603. The surface of the protective cover 605 has several heat dissipation holes. The protective cover 605 protects the servo motor 603 from external impacts and dust contamination. The heat dissipation holes ensure effective heat dissipation of the motor and improve its service life. A base plate 612 is slidably connected to the inner wall of the moving frame 606. The base plate 612 is slidably connected to the surface of the mandrel 4 and is used to further support the mandrel 4. The base plate 612 that is compatible with the mandrel 4 needs to be placed in the moving frame 606 before the mandrel 4 is installed.

[0034] In the embodiments of this utility model, please refer to Figure 6The auxiliary structure 7 includes two auxiliary frames 71, which are fixedly connected to the body 1. A bidirectional screw 72 is rotatably connected to the inner wall of each auxiliary frame 71. Two auxiliary plates 73 are threadedly connected to the arc surface of the bidirectional screw 72. The two auxiliary plates 73 are slidably connected to the inner wall of the auxiliary frames 71. A round rod 74 is fixedly connected to the inner wall of the auxiliary frames 71, and the arc surface of the round rod 74 is slidably connected to the auxiliary plates 73. Operating the bidirectional screw 72 and using the auxiliary plates 73 clamps and fixes the mandrel 4. The auxiliary structure 7 facilitates easy assembly and disassembly of the mandrel 4 from the body 1. The user can replace the appropriate mandrel 4 according to the inner diameter of the tube 5 to be processed, thereby improving the efficiency of subsequent maintenance operations. Anti-slip pads 75 are fixedly connected to the side of the two auxiliary plates 73 that are close to each other. The anti-slip pads 75 are rubber pads. The anti-slip pads 75 increase the friction to ensure that the mandrel 4 is firmly clamped and prevents it from loosening during processing. One end of the bidirectional screw 72 is fixedly connected to a disc 76. A handle 77 is slidably connected to the inner wall of the disc 76. The handle 77 can be inserted into the disc 76. The bidirectional screw 72 can be easily rotated using the lever principle to realize the clamping or loosening operation of the mandrel 4, saving time and effort.

[0035] The working principle of the punching equipment for producing extended tees provided by this utility model is as follows: By setting the adjustment structure 6, first take the baffle 611 that matches the diameter of the mandrel 4, align the baffle 611 with the moving frame 606, and put the baffle 611 on the mandrel 4 and inside the moving frame 606 from top to bottom. Then rotate the limiting rod 608, and the limiting rod 608 moves towards the moving frame 606 by means of the thread. The limiting rod 608 drives the clamping plate 609 to move. The clamping plate 609 cooperates with the moving frame 606 to clamp and position the baffle 611. During this process, the clamping plate 609 drives the sliding rod 610 to slide along the moving frame 606. Then start the servo motor 603. The output end of the servo motor 603 drives the adjusting rod 602 to rotate along the support frame 601. The moving frame 606 moves along the fixed frame 607 via the thread, and the moving frame 606 in turn moves the baffle 611 along the surface of the mandrel 4. The distance between the baffle 611 and the mold 3 is adjusted according to the position where the tube body 5 needs to be punched, which helps the user to position the tube body 5. It is suitable for punching tee holes in tube bodies 5 with a certain length. The scale 604 provides an intuitive positioning reference, which makes it easy for the operator to accurately set the position of the baffle 611 and improve the positioning accuracy. The protective cover 605 protects the servo motor 603 from external impact and dust contamination. The heat dissipation holes ensure that the motor can effectively dissipate heat and improve its service life. The base plate 612 is used to further support the mandrel 4. The base plate 612 that is compatible with the mandrel 4 needs to be placed in the moving frame 606 before the mandrel 4 is installed.

[0036] By setting up the auxiliary structure 7, the mandrel 4 is first passed through the two auxiliary frames 71, so that the mandrel 4 is located between the two auxiliary plates 73 in the same auxiliary frame 71. Then, the bidirectional screw 72 is rotated. The bidirectional screw 72 drives the two auxiliary plates 73 to move towards each other simultaneously through the thread. During this process, the auxiliary plates 73 always move along the round rod 74. Continue to rotate the bidirectional screw 72, and the two auxiliary plates 73 clamp and position the surface of the mandrel 4, so that the position of the mandrel 4 is fixed. The anti-slip pad 75 increases the friction to ensure that the mandrel 4 is firmly clamped and prevents it from loosening during processing. The lever 77 can be inserted into the disc 76, and the bidirectional screw 72 can be easily rotated using the lever principle to realize the clamping or loosening operation of the mandrel 4, saving time and effort.
