Description

Technical Field

[0001] This utility model relates to the field of stainless steel pipe fitting flanging technology, and in particular to a flanging device for the production of stainless steel press-fit pipe fittings. Background Technology

[0002] A search revealed that application number 202220249165.2 discloses a flange-flanging device for producing stainless steel press-fit pipe fittings, comprising a base, a support frame provided on one side of the top of the base, a protective shell provided on the top of the base, a first mounting plate provided at the middle position of the top of the protective shell, a fixing block fixedly connected to the top of the first mounting plate, a pipe fitting body provided outside the fixing block, a hydraulic cylinder mounted on the top of the support frame, and a connecting plate fixedly connected to the bottom of the hydraulic cylinder.

[0003] The stainless steel press-fit pipe fitting production flanging device in this patent application uses a first fixing pin inserted into a first mounting hole to install a fixing block, which facilitates the replacement of the fixing block to perform flanging processing on pipe fittings of different diameters. However, in this process, since the device needs to replace the fixing block of the corresponding specification when flanging pipe fittings of different diameters, the operation is relatively cumbersome, and the large number of fixing blocks of different specifications is also inconvenient for storage and retrieval, which brings inconvenience to the use of the device. Therefore, we propose a stainless steel press-fit pipe fitting production flanging device. Utility Model Content

[0004] The present invention mainly addresses the technical problems existing in the prior art and provides a flange-flanging device for the production of stainless steel press-fit pipe fittings.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a flanged device for producing stainless steel press-fit pipe fittings, comprising an equipment base and a support frame disposed on one side of the top of the equipment base. The support frame is equipped with a height-adjustable flanged assembly. The equipment base is equipped with a limiting clamp assembly for clamping and fixing the pipe fittings. An mounting plate is fixedly installed at the center of the top wall of the equipment base. A positioning mechanism is provided at the top of the mounting plate. The positioning mechanism includes four horizontally adjustable fixing blocks disposed at the center of the top wall of the mounting plate. A longitudinal adjustment groove is provided at the center of the top wall of the mounting plate. The left side of the top wall of the mounting plate... Symmetrical transverse adjustment grooves are provided on both sides. An adjustment mechanism that drives four fixed blocks to move horizontally is provided inside the longitudinal adjustment groove and the two transverse adjustment grooves. The adjustment mechanism includes a bidirectional threaded rod rotatably connected inside the longitudinal adjustment groove, two adjusting threaded rods rotatably connected inside the two transverse adjustment grooves, and four adjusting nut blocks slidably connected inside the longitudinal adjustment groove and the two transverse adjustment grooves. The four adjusting nut blocks are respectively threaded to the outer walls of the front ends of the bidirectional threaded rod and the outer walls of the two adjusting threaded rods. The bottom ends of the four fixed blocks are respectively fixedly installed to the top ends of the four adjusting nut blocks.

[0006] Furthermore, the outer walls at both ends of the bidirectional threaded rod are respectively provided with threads in opposite directions.

[0007] Furthermore, the outer walls of the two adjusting threaded rods are respectively provided with threads in opposite directions.

[0008] Furthermore, a drive steering gear is fixedly installed at the middle position of the outer wall surface of the adjusting threaded rod.

[0009] Furthermore, one end of each of the two adjusting threaded rods extends through the sidewalls of the two transverse adjusting slides to the inner side of the longitudinal adjusting slide, and the two ends of the two adjusting threaded rods located inside the longitudinal adjusting slide are fixedly installed with two passive steering gears that mesh with the active steering gear.

[0010] Furthermore, the front end of the bidirectional threaded rod extends through the front wall of the longitudinal adjusting groove to the outside and is fixedly fitted with an adjusting knob.

[0011] Furthermore, the four fixed blocks are distributed in a ring with equal spacing.

[0012] Furthermore, four guide ramps are provided at the top of the side wall surfaces of the four fixing blocks.

[0013] This utility model provides a flange-flanging device for the production of stainless steel press-fit pipe fittings. It has the following advantages:

[0014] 1. This stainless steel press-fit pipe fitting production flanging device, through the setting of adjustment mechanism and positioning mechanism, in use, the pipe fitting to be processed is placed on the outer wall of four fixed blocks, and then the outer wall of the pipe fitting is clamped and fixed by the limiting clamp assembly. Finally, the pipe fitting is flanged by the flanging assembly. When it is necessary to process pipe fittings of different diameters, the adjustment knob can be turned to drive the bidirectional threaded rod to rotate. The bidirectional threaded rod drives two adjusting threaded rods to rotate synchronously through the active steering gear and the passive steering gear, forcing the four fixed blocks that are threaded to both ends of the bidirectional threaded rod and the outer walls of the two adjusting threaded rods to move closer or further apart, so that the outer wall surface of the four fixed blocks can abut against the inner wall of the pipe fittings of different diameters to form a positioning effect. The above operation is simple and practical, and the structure is reasonable and compact. This allows the equipment to form a positioning effect for pipe fittings of different diameters without replacing the fixed blocks, improving the convenience of the equipment.

[0015] 2. This stainless steel press-fit pipe fitting production flange device, by setting guide slopes, the tops of the four fixed blocks can form a guiding effect on the inner wall of the pipe fitting, making it convenient for the pipe fitting to be fitted onto the outer wall of the four fixed blocks, thus improving the practicality of the equipment.

Detailed Implementation

[0023] A flange-flanging device for producing stainless steel press-fit pipe fittings, such as Figure 1-4 As shown, the device includes a base 10 and a support frame 12 disposed on one side of the top of the base 10. The support frame 12 is equipped with a height-adjustable flange assembly 13. The base 10 is equipped with a limiting clamp assembly 14 for clamping and fixing pipe fittings. Both the flange assembly 13 and the limiting clamp assembly 14 are prior art and will not be described in detail. A mounting plate 15 is fixedly installed at the center of the top wall of the base 10. A positioning mechanism is provided at the top of the mounting plate 15. The positioning mechanism includes four horizontally adjustable retaining elements disposed at the center of the top wall of the mounting plate 15. The top wall of the fixed block 21 and the mounting plate 15 has a longitudinal adjustment groove 16 at the center and two transverse adjustment grooves 17 symmetrically on the left and right sides of the top wall of the mounting plate 15. The longitudinal adjustment groove 16 and the two transverse adjustment grooves 17 are equipped with an adjustment mechanism that drives the four fixed blocks 21 to move horizontally. The adjustment mechanism includes a bidirectional threaded rod 18 rotatably connected to the longitudinal adjustment groove 16 and two adjusting threaded rods 19 rotatably connected to the two transverse adjustment grooves 17. Four adjusting nut blocks 20 are slidably connected inside the groove 17. These four adjusting nut blocks 20 are threaded to the outer walls of both ends of the front end of the bidirectional threaded rod 18 and the outer walls of the two adjusting threaded rods 19. The outer walls of both ends of the front end of the bidirectional threaded rod 18 have threads in opposite directions, and the outer walls of the two adjusting threaded rods 19 also have threads in opposite directions. A drive steering gear 22 is fixedly installed at the middle of the outer wall surface of the adjusting threaded rod 19. The ends of the two adjusting threaded rods 19 that are close to each other penetrate the side walls of the two transverse adjusting grooves 17. Extending into the inner side of the longitudinal adjustment slide 16, two adjusting threaded rods 19 are fixedly installed at one end of the inner side of the longitudinal adjustment slide 16 with two passive steering gears 23 that mesh with the active steering gear 22. The front end of the bidirectional threaded rod 18 extends through the front wall of the longitudinal adjustment slide 16 to the outside and is fixedly installed with an adjusting knob 24. The bottom ends of the four fixing blocks 21 are fixedly installed with the top ends of the four adjusting nut blocks 20 respectively. The four fixing blocks 21 are distributed in a ring with equal spacing. The top of the side wall of the four fixing blocks 21 is provided with four guide slopes 25.

[0024] The working principle of this utility model is as follows: In use, the pipe fitting to be processed is placed on the outer wall of the four fixing blocks 21, and then the outer wall of the pipe fitting is clamped and fixed by the limiting clamp assembly 14. Finally, the pipe fitting is flanged by the flanging assembly 13. When processing pipe fittings of different diameters is required, the adjusting knob 24 can be rotated to drive the bidirectional threaded rod 18 to rotate. The bidirectional threaded rod 18 drives the two adjusting threaded rods 19 to rotate synchronously through the active steering gear 22 and the passive steering gear 23, forcing the two ends of the bidirectional threaded rod 18 and the two adjusting threaded rods 19 to rotate. The four fixing blocks 21 with external thread connection move closer or further apart, so that the outer wall surface of the four fixing blocks 21 can abut against the inner wall of pipe fittings of different diameters to form a positioning effect. The above operation is simple and practical, and the structure is reasonable and compact. This allows the equipment to form a positioning effect for pipe fittings of different diameters without replacing the fixing blocks 21, improving the convenience of the equipment. The top of the four fixing blocks 21 can form a guiding effect on the inner wall of the pipe fitting through the guide slope 25, making it convenient for the pipe fitting to be fitted onto the outer wall surface of the four fixing blocks 21, improving the practicality of the equipment.
