Description

Technical Field

[0001] This utility model relates to the field of forging technology for inclined pipes, and in particular to a fixture for forging inclined pipes. Background Technology

[0002] Inclined pipe forgings are important pipe connection components, widely used in industries such as petroleum, chemical, and power. They are used to connect pipes of different diameters or angles. Their centerline is not perpendicular to the surface of the cylinder and has a certain inclination angle in the circumferential or longitudinal direction. Inclined pipe forgings require multiple processing steps during production. In order to facilitate the processing of inclined pipe forgings, clamps are used to fix them.

[0003] When machining oblique pipe forgings, since the two ends are not on the same axis, the positions of both ends must be precisely fixed. However, the bending angles of different oblique pipe forgings are different, which exposes the obvious limitations of common fixtures when dealing with oblique pipe forgings with different degrees of bending. They cannot reliably and effectively fix the two ends of the oblique pipe forgings. Therefore, this application proposes a fixture for machining oblique pipe forgings. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fixture for processing oblique pipe forgings, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a fixture for processing oblique tube forgings includes a base, which is divided into a rectangular plate and a semi-circular ring. The ring is fixedly installed on one side of the plate. A semi-circular arc-shaped groove is formed on the ring, and sliding grooves are formed on both sides of the inner wall of the arc-shaped groove. A cross slider is slidably installed between the two sliding grooves on the inner wall of the arc-shaped groove. A first clamping mechanism is fixedly installed on the top of the cross slider and located at the top of the ring. A second clamping mechanism is fixedly installed on the left end of the top of the plate. A toothed groove is formed on the outer wall of the ring. A positioning component that can be engaged in the toothed groove is fixedly installed on the first clamping mechanism.

[0006] Optionally, the second clamping mechanism includes a storage seat, a support frame, a clamping block, and a first bolt. The storage seat is fixedly installed on the top of the plate. The support frame is configured as an inverted L-shape, and the vertical end of the support frame is fixedly installed on one side of the top of the storage seat. The clamping block is located below the horizontal part of the support frame. A groove is provided on the top of the clamping block, and a bearing is fixedly installed in the groove. The first bolt is inserted through the center of the horizontal part of the support frame, and the bottom end of the first bolt is fixedly connected between the inner ring wall of the bearing. V-shaped clamping grooves are provided on the bottom of the clamping block and the top of the storage seat. Two first ball grooves are provided on the side of the clamping block near the vertical part of the support frame. Rotatable first balls are provided in both first ball grooves. The two first balls extend out of the side wall of the first ball groove and fit against the inner side of the vertical part of the support frame.

[0007] Optionally, the first clamping mechanism and the second clamping mechanism have the same structure, and the storage seat in the first clamping mechanism is fixedly installed on the top of the cross slider.

[0008] Optionally, the positioning assembly includes a connecting plate, a limiting plate, and a second bolt. The connecting plate is fitted to the outer wall of the ring, and the top of the connecting plate is connected to the first clamping mechanism. A groove is provided on the inner side of the connecting plate, and the limiting plate is movably disposed in the groove. One side of the limiting plate is provided with teeth, and the teeth on one side of the limiting plate can extend into the tooth groove on the outer wall of the ring and engage with it. A threaded hole communicating with the groove is provided on the outer side of the connecting plate, and the second bolt is threaded into the threaded hole, with one end of the second bolt abutting against the side of the limiting plate away from the tooth groove.

[0009] Optionally, positioning rods are fixedly connected to both ends of the limiting plate on the side away from the tooth groove. Both positioning rods pass through the connecting plate and extend to its outer side. Springs are sleeved on both positioning rods, and the two ends of the springs are fixedly connected to the outer side of the connecting plate and the end of the positioning rod, respectively.

[0010] Optionally, scale markings are evenly distributed at the bottom of the outer wall of the ring, and a pointer pointing to the scale markings is fixedly installed at the bottom of the connecting plate.

[0011] Optionally, a second ball groove is provided at both ends of the horizontal section of the cross slider, and a second ball is provided in each second ball groove. The side wall of each second ball extending out of the second ball groove contacts the inner wall of the sliding groove.

[0012] The beneficial effects of this utility model are:

[0013] Before clamping the inclined tube forging to be processed, the position of the first clamping mechanism on the ring body needs to be adjusted according to the bending angle of the inclined tube forging. Specifically, the first clamping mechanism is moved to drive the cross slider to move in the slot and sliding groove. During the operation, the scale marks on the outer wall of the ring body can be used as a reference to make precise adjustments to the first clamping mechanism so that the included angle between the first clamping mechanism and the second clamping mechanism is completely consistent with the bending angle of the inclined tube forging to be processed. In this way, the two ends of the inclined tube forging with different degrees of bending can be firmly and effectively clamped and fixed, ensuring the smooth progress of the processing.

[0014] After adjustment, the oblique tube forging to be processed is placed on the placement seat of the first clamping mechanism and the second clamping mechanism. Then, the first bolt on the support frame is turned. As the first bolt rotates, it pushes the clamping block to move downward. The bottom of the clamping block and the clamping groove at the top of the placement seat cooperate with each other, gradually clamping the two ends of the oblique tube forging tightly. This completes the fixed clamping work on the two ends of the oblique tube forging, ensuring that the oblique tube forging will not shift during subsequent processing, thus guaranteeing the accuracy and quality of processing.

[0023] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] Please see Figures 1-6 This utility model provides a technical solution: a fixture for processing oblique pipe forgings, including a base, which is divided into a rectangular plate 1 and a semi-circular ring 2. The ring 2 is fixedly installed on one side of the plate 1. A semi-circular arc-shaped groove 3 is formed on the ring 2, and sliding grooves 4 are formed on both sides of the inner wall of the arc-shaped groove 3. A cross slider 5 is slidably installed between the two sliding grooves 4 on the inner wall of the arc-shaped groove 3. A first clamping mechanism 6 is fixedly installed on the top of the cross slider 5, located at the top of the ring 2. A second clamping mechanism 7 is fixedly installed on the left end of the top of the plate 1. A toothed groove 8 is formed on the outer wall of the ring 2. A positioning component 9 that can engage in the toothed groove 8 is fixedly installed on the first clamping mechanism 6. By adjusting the position and angle of the first clamping mechanism 6 and using the positioning component 9 to fix the adjusted position of the first clamping mechanism 6, the first clamping mechanism 6, in conjunction with the second clamping mechanism 7, can clamp and fix oblique pipe forgings with different degrees of bending.

[0025] like Figure 2 and Figure 4As shown, the second clamping mechanism 7 includes a storage base 71, a support frame 72, a clamping block 73, and a first bolt 75. The storage base 71 is fixedly installed on the top of the plate 1. The support frame 72 is configured as an inverted L-shape, and the vertical end of the support frame 72 is fixedly installed on one side of the top of the storage base 71. The clamping block 73 is located below the horizontal part of the support frame 72. A groove is formed on the top of the clamping block 73, and a bearing 74 is fixedly installed in the groove. The first bolt 75 is inserted through the center of the horizontal part of the support frame 72, and the bottom end of the first bolt 75 is fixedly connected between the inner ring wall of the bearing 74. V-shaped clamping grooves are formed on the bottom of the clamping block 73 and the top of the storage base 71. Two first ball grooves are provided on the side of the clamping block 73 near the vertical part of the support frame 72. A rotatable first ball 76 is provided in each of the two first ball grooves. The side walls of the two first balls 76 protrude from the first ball grooves and fit against the inner side of the vertical part of the support frame 72. By turning the first bolt 75 on the support frame 72, the clamping block 73 will be pushed to move downward as the first bolt 75 rotates. The bottom of the clamping block 73 cooperates with the clamping groove at the top of the placement seat 71, thereby completing the fixed clamping of the end of the inclined tube forging. The two first balls 76 can prevent the clamping block 73 from contacting the support frame 72, which can effectively reduce the resistance encountered by the clamping block 73 when moving up and down.

[0026] like Figure 1 and Figure 2 As shown, the first clamping mechanism 6 and the second clamping mechanism 7 have the same structure, and the placement seat 71 in the first clamping mechanism 6 is fixedly installed on the top of the cross slider 5. The two ends of the inclined tube forging to be processed can be effectively clamped and fixed through the first clamping mechanism 6 and the second clamping mechanism 7.

[0027] like Figure 2 and Figure 5 As shown, the positioning component 9 includes a connecting plate 91, a limiting plate 93, and a second bolt 94. The connecting plate 91 is attached to the outer wall of the ring 2, and the top of the connecting plate 91 is connected to the first clamping mechanism 6. A groove 92 is provided on the inner side of the connecting plate 91. The limiting plate 93 is movably disposed in the groove 92. One side of the limiting plate 93 is provided with teeth, and the teeth on one side of the limiting plate 93 can extend into the tooth groove 8 on the outer wall of the ring 2 and engage with it. A screw hole communicating with the groove 92 is provided on the outer side of the connecting plate 91. The second bolt 94 is threaded into the screw hole, and one end of the second bolt 94 abuts against the side of the limiting plate 93 away from the tooth groove 8. After adjusting the position of the first clamping mechanism 6, the second bolt 94 is turned to push the limiting plate 93 out of the groove 92, so that the teeth on one side of the limiting plate 93 extend into the tooth groove 8 and engage, thereby fixing the position of the first clamping mechanism 6.

[0028] like Figure 2 and Figure 5As shown, both ends of the limiting plate 93 away from the tooth groove 8 are fixedly connected to positioning rods 95. Both positioning rods 95 pass through the connecting plate 91 and extend to its outer side. Springs 96 are sleeved on both positioning rods 95. The two ends of the springs 96 are fixedly connected to the outer side of the connecting plate 91 and the end of the positioning rods 95, respectively. The positioning rods 95 make the movement of the limiting plate 93 by the second bolt 94 more stable, while the springs 96 can play the role of resetting the limiting plate 93.

[0029] like Figure 2 and Figure 5 As shown, scale marks 10 are evenly arranged at the bottom of the outer wall of the ring 2. A pointer 97 pointing to the scale marks 10 is fixedly installed at the bottom of the connecting plate 91. Through the cooperation of the pointer 97 and the scale marks 10, the position of the first clamping mechanism 6 that needs to be adjusted can be precisely adjusted so that the included angle between the first clamping mechanism 6 and the second clamping mechanism 7 is consistent with the bending angle of the inclined tube forging to be processed.

[0030] like Figure 3 and Figure 6 As shown, the ends of both sides of the horizontal section of the cross slider 5 are provided with second ball grooves, and a second ball 51 is provided in each second ball groove. The side wall of each second ball 51 protruding from the second ball groove contacts the inner wall of the sliding groove 4. The second ball 51 can reduce the contact area between the cross slider 5 and the inner wall of the sliding groove 4, thereby reducing the friction between the two and making the cross slider 5 move more effortlessly.

[0031] Although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
