Description

Technical Field

[0001] This utility model relates to the field of oblique pipe forging technology, and in particular to a positioning and fixing mechanism for oblique pipe forging. 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 tilt angle in the circumferential or longitudinal direction. The positioning and fixing mechanism is a device for fixing and clamping the inclined pipe forgings. This device can be used to position the inclined pipe forgings to be processed.

[0003] Existing common positioning and fixing mechanisms for inclined pipe forgings have significant limitations in practical applications. Due to the bent shape of the inclined pipe forgings and the different bending angles of different products, traditional fixing mechanisms are difficult to adapt to the diverse forging shapes, resulting in insufficient positioning accuracy and stability when clamping inclined pipe forgings with different bending angles. In addition, these mechanisms usually cannot effectively fix both ends of the inclined pipe at the same time, which further affects the stability and positioning reliability of the forging during the processing. To address the above problems, this application proposes a positioning and fixing mechanism for inclined 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 positioning and fixing mechanism for inclined pipe forgings 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 positioning and fixing mechanism for a slanted pipe forging, comprising a base, a support column fixedly installed at the top left end of the base, a lifting tube movably sleeved on the support column, a storage frame with an open front side fixedly installed at the top end of the lifting tube, a storage groove opened at the top of the inner wall of the storage frame, a clamping block movably installed in the storage groove, a V-shaped clamping groove opened at the bottom of the clamping block and at the top of the inner wall of the storage frame, a through-hole opened on the side of the clamping block, an adjustable limiting component inserted into the through-hole, a moving groove opened on the right half of the top of the base, and a moving mechanism located at the top of the base is provided in the moving groove.

The rod shaft is inserted through the slot, and annular grooves are opened at both ends of the rod shaft. The width of the movable plate is greater than the width of the base. The two third hydraulic rods are fixedly installed at the middle position of the bottom of both ends of the movable plate. The telescopic ends of the two third hydraulic rods penetrate the movable plate, and collars are fixedly installed at the telescopic ends of the two third hydraulic rods. The two collars are rotatably sleeved on the annular grooves at both ends of the rod shaft.

[0008] Optionally, the limiting assembly includes an adjusting plate, a pressing plate, and an adjusting bolt. The adjusting plate is configured as an L-shape with a tilting shape. The horizontal part of the adjusting plate is inserted through a hole on the side of the clamping block. Multiple equally spaced grooves are provided on the top of the adjusting plate.

[0011] The beneficial effects of this utility model are:

[0012] This positioning and fixing mechanism enables stable clamping and flexible adaptation of inclined pipe forgings.

Then, the position is adjusted by the moving mechanism, and the flipping component is flexibly adjusted according to the degree of bending and the position of the inclined end of the forging, so that the flipping plate fits tightly against the inclined end of the forging. Finally, the position of the adjusting plate in the positioning component is adjusted, and the adjusting bolt is turned to push the extrusion plate to firmly press against the horizontal end of the forging. This mechanism significantly improves the clamping stability of the forging through the dual fixing method of horizontal end clamping and two-end extrusion. At the same time, the adjustable characteristics of the flipping component in the moving mechanism allow it to adapt to inclined pipe forgings with different degrees of bending, effectively overcoming the limitations of traditional devices.

[0021] 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.

[0022] Please see Figures 1-6This utility model provides a technical solution: a positioning and fixing mechanism for a slanted pipe forging, including a base 1, a support column 2 fixedly installed at the top left end of the base 1, a lifting tube 3 movably sleeved on the support column 2, a storage frame 5 with an open front side fixedly installed at the top end of the lifting tube 3, a storage groove 6 opened at the top of the inner wall of the storage frame 5, a clamping block 8 movably installed in the storage groove 6, V-shaped clamping grooves opened at the bottom of the clamping block 8 and the top of the inner wall of the storage frame 5, and a through-hole 96 opened on the side of the clamping block 8, into which an adjustable limiting device is inserted. Component 9, the right half of the top of the base 1 has a moving groove 10, and a moving mechanism 12 located on the top of the base 1 is set in the moving groove 10. Through the coordinated operation of the storage frame 5 and the clamping block 8, the horizontal and vertical parts of the forging are precisely clamped. Then the position of the moving mechanism 12 is adjusted, and the flipping component 123 is flexibly adjusted according to the bending degree of the forging and the position of the inclined end, so that the flipping plate 1230 is tightly attached to the inclined end of the forging. Finally, the position of the adjusting plate 91 in the positioning component is adjusted, and the adjusting bolt 95 is turned to push the pressing plate 92 to firmly press against the horizontal end of the forging.

[0023] like Figure 1 , Figure 5 and Figure 6 As shown, the right end of the base 1 is rotatably connected to a screw 11 extending into the moving groove 10. The moving mechanism 12 includes a moving plate 121, a moving block 122, and a flipping assembly 123. The moving block 122 is located in the moving groove 10 and threaded onto the screw 11. The moving plate 121 is fixedly installed on the moving block 122 and located on the top of the base 1. The flipping assembly 123 is hinged to the top of the moving plate 121. By turning the screw 11, it rotates threadedly with the moving block 122 in the moving mechanism 12, thereby driving the moving block 122 to move within the moving groove 10, thus realizing the adjustment of the position of the moving mechanism 12.

[0024] like Figure 1 , Figure 5 and Figure 6As shown, the flipping assembly 123 includes a flipping plate 1230, a fixed shaft 1231, a rod shaft 1233, and two third hydraulic rods 1234. The fixed shaft 1231 is fixedly installed on the left end of the top of the movable plate 121. The left end of the flipping plate 1230 is rotatably sleeved on the fixed shaft 1231, and a through slot 1232 is provided on the side of the flipping plate 1230. The rod shaft 1233 is inserted through the slot 1232, and annular grooves are provided at both ends of the rod shaft 1233. The width of the movable plate 121 is greater than the width of the base 1. The two third hydraulic rods 1234 are respectively fixedly installed at the middle position of the bottom of both ends of the movable plate 121. The telescopic ends of the two third hydraulic rods 1234 penetrate the movable plate 121, and the two... The telescopic ends of the third hydraulic rod 1234 are all fixedly equipped with collars 1235. The two collars 1235 are respectively rotatably sleeved on the annular grooves at both ends of the rod shaft 1233. By controlling the extension of the two third hydraulic rods 1234, the collars 1235 at their telescopic ends drive the rod shaft 1233 to move in the groove 1232 on the side of the flip plate 1230. As the horizontal height of the rod shaft 1233 gradually increases, the left end of the flip plate 1230 can be rotated around the fixed shaft 1231. The position of the moving mechanism 12 and the tilt angle of the flip plate 1230 can be released and adjusted by the degree of bending of the inclined pipe forging and the position of the tilt end, so that the flip plate 1230 can be stably pressed against the tilt end of the inclined pipe forging.

[0025] like Figures 1-4As shown, the limiting assembly 9 includes an adjusting plate 91, a pressing plate 92, and an adjusting bolt 95.

The adjusting plate 91 is adjusted appropriately according to the position of the horizontal end of the inclined tube forging. The position of the adjusting plate 91 can be fixed by using the positioning bolt 99 to pass through the fixing block 98 and insert it into the groove 97 at an appropriate position on the adjusting plate 91. Then, the position of the extrusion plate 92 is finely adjusted by turning the adjusting bolt 95 to push the extrusion plate 92 closer to the inclined tube forging. Finally, the extrusion plate 92 abuts against the horizontal end of the inclined tube forging. Under the action of the two positioning rods 93, the extrusion plate 92 can be placed on the right side of the vertical part of the adjusting plate 91, and the extrusion plate 92 can be made more stable when moving.
