Description

Technical Field

[0001] This invention relates to the field of stainless steel pipe fittings technology, specifically to a forming equipment for stainless steel pipe fittings. Background Technology

[0002] Stainless steel pipe fittings are a type of pipe fitting made of stainless steel, widely used in fields such as oil transmission, chemical transportation, and urban construction. They are an extremely widely used device. During the production of stainless steel pipe fittings, there are certain requirements for the shape of the pipe fittings, so the pipe fittings need to be formed. The existing technology generally uses liquid high-pressure forming technology, which has the characteristics of high precision and easy operation.

[0003] An existing patent (publication number: CN112935062A) discloses an internal high-pressure forming device for stainless steel pipe fittings, including a base, guide pillars, support plate, hydraulic cylinder, fixing plate, moving mold for pipe fittings, fixed mold for pipe fittings, support seat, feeding head, water supply system, and recycling system. In the process of implementing this solution, the inventors discovered the following problems in the existing technology that have not been adequately addressed: 1. During operation, the existing device requires combining the moving mold and the fixed mold to position the pipe fitting and using liquid injection for internal high-pressure forming. However, after processing, due to the internal expansion and deformation of the pipe fitting, it is easy for the pipe fitting to stick to the mold, making disassembly difficult; 2. Because internal high-pressure forming is used, liquid splashing is prone to occur during processing. A single collection pipe is insufficient for effective liquid recovery, and the splashed liquid can easily splash onto equipment surfaces or electronic components, causing unnecessary trouble and hindering liquid recovery. Summary of the Invention

[0004] The purpose of this invention is to provide a forming device for stainless steel pipe fittings to solve the problems mentioned in the background art: 1. inconvenience in removing finished products; 2. inconvenience in liquid recovery. To achieve the above objective, this invention provides the following technical solution: a forming device for stainless steel pipe fittings, comprising a forming machine body, a fixed mold fixed at the top of the forming machine body, a hydraulic lifting plate horizontally arranged above the fixed mold, guide rods for stabilizing the vertical movement of the hydraulic lifting plate fixed at the top of both sides of the forming machine body, and through holes opened inside the two sets of guide rods; a moving mold fixed at the bottom of the hydraulic lifting plate.

[0005] The outer wall of the moving mold is fitted with a removal assembly for moving stainless steel pipe fittings, and the inner wall of the forming machine body is provided with a collection assembly.

[0006] Preferably, the removal assembly includes a positioning plate and a placement plate. The inner wall of the positioning plate is sleeved with the outer wall of the moving mold. Positioning sleeves are fixedly connected to both side walls of the positioning plate. The inner wall of the placement plate is sleeved with the outer wall of the fixed mold. Placement sleeves are fixed to both ends of the placement plate, and the shape and specifications of the placement sleeves are the same as those of the positioning sleeves. A telescopic spring rod is fixedly connected to the bottom end of the placement plate.

[0007] Preferably, the inner side of the guide rod is provided with a sliding groove, and the sliding groove is slidably engaged with both ends of the positioning plate.

[0008] Preferably, the positioning plate includes a fixing block and a plug-in rod. The side wall of the fixing block is fixedly connected to the outer wall of the storage sleeve. The fixing block has a plug-in groove inside, and a turntable is rotatably connected inside the plug-in groove. A slot is opened on one side of the turntable, and the side wall of the slot of the turntable has a bevel formed by machining. The outer wall of the plug-in rod is fixedly connected to the outer wall of the positioning sleeve. A limiting block is fixed on the side wall of the plug-in rod, and the outer wall of the limiting block has an arc-shaped edge formed by machining.

[0009] Preferably, the interior of the turntable is hollow, the shaft end of the turntable extends to the outside of the fixed block and is fixedly connected to a knob, and a torsion spring is sleeved on the shaft end of the turntable.

[0010] Preferably, the hydraulic lifting plate includes a transmission rod and a protective plate. One side of the transmission rod is hinged to the side wall of the hydraulic lifting plate. Two sets of transmission rods are symmetrically arranged about the axis of the hydraulic lifting plate. The bottom end of the transmission rod is hinged to the protective plate. The protective plate is made of acrylic material. The axial end of the protective plate is hinged to the molding machine body. Two sets of protective plates are symmetrically arranged about the axis of the molding machine body.

[0011] Preferably, the collection component includes a collection chamber and a permeation screen. The outer wall of the collection chamber is fixedly connected to the inner wall of the molding machine body. The permeation screen is opened in the top wall of the molding machine body.

The bottom end of the collection funnel is connected to a conveying pipe.

[0012] Preferably, the top wall of the molding machine body and the permeation mesh are arranged in a concave structure, and the permeation mesh and the filter mesh are arranged horizontally.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] In this invention, the positioning sleeve and the storage sleeve can clamp and restrict the stainless steel pipe as the hydraulic lifting plate moves downward. After processing, they move together with the hydraulic lifting plate to remove the stainless steel pipe from the fixed mold. By releasing the fixing structure of the positioning sleeve and the storage sleeve, the material can be unloaded, thereby avoiding the tight fit between the stainless steel pipe and the mold, which would cause inconvenience to the operator.

[0015] In this invention, the combination of a hydraulic lifting plate and a transmission rod causes the two sets of protective plates to close when the hydraulic lifting plate moves down, shielding the end face where the user operates and preventing liquid from splashing everywhere. At the same time, the liquid, being blocked, flows downward and is sent through the permeation mesh into the recovery chamber for collection and output. Attached Figure Description

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Please see Figures 1 to 6 The present invention provides a technical solution: a forming equipment for stainless steel pipe fittings, including a forming machine body 1, a fixed mold 2 fixed at the top of the forming machine body 1, a hydraulic lifting plate 3 horizontally arranged above the fixed mold 2, guide rods 4 for stabilizing the vertical movement of the hydraulic lifting plate 3 fixed at the top of both sides of the forming machine body 1, and through holes opened inside the two sets of guide rods 4, and a moving mold 5 fixed at the bottom of the hydraulic lifting plate 3.

[0025] The outer wall of the moving mold 5 is fitted with a removal component 6 for moving stainless steel pipe fittings. The inner wall of the forming machine body 1 is provided with a collection component 7. By setting the placement sleeve and positioning sleeve 62 in the removal component 6, the two can be locked when closed to clamp the stainless steel pipe fittings. This allows the stainless steel pipe fittings to be pulled out of the fixed mold 2 by setting the hydraulic lifting plate 3, making it convenient for the staff to operate.

[0026] In this embodiment, as Figure 1 , Figure 2 and Figure 4 As shown, the removal component 6 includes a positioning plate 61 and a placement plate 63. The inner wall of the positioning plate 61 is sleeved with the outer wall of the moving mold 5. Positioning sleeves 62 are fixedly connected to both side walls of the positioning plate 61. The inner wall of the placement plate 63 is sleeved with the outer wall of the fixed mold 2. Placement sleeves are fixed to both ends of the placement plate 63, and the shape and specifications of the placement sleeves are the same as those of the positioning sleeves 62. A telescopic spring rod 64 is fixedly connected to the bottom end of the placement plate 63. The operator can manually place the stainless steel pipe on the placement sleeve. As the hydraulic lifting plate 3 moves down, the hydraulic lifting plate 3 drives the positioning plate 61 to move down together, causing the positioning sleeves 62 and the placement sleeves to clamp the two ends of the stainless steel pipe. As the hydraulic lifting plate 3 continues to move down, the positioning sleeves 62 move down through the telescopic spring rod 64 until the fixed mold 2 and the moving mold 5 clamp and fix the stainless steel pipe. Through the through holes on the two sets of guide rods 4, external hydraulic pipes can be inserted into the stainless steel pipe for internal high-pressure forming.

[0027] In this embodiment, as Figure 2 As shown, a sliding groove is provided on the inner side of the guide rod 4, and the sliding groove is slidably engaged with both ends of the positioning plate 61. As the hydraulic lifting plate 3 moves up and down, the positioning plate 61 is driven to move synchronously through the moving mold 5, so as to facilitate the movement of the positioning sleeve 62 to the surface of the storage sleeve for fixed connection, which is convenient for restricting the stainless steel pipe fittings.

[0028] In this embodiment, as Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the positioning plate 61 includes a fixing block 631 and a connecting rod 633. The side wall of the fixing block 631 is fixedly connected to the outer wall of the storage sleeve. The fixing block 631 has a connecting groove inside, and a turntable 632 is rotatably connected inside the connecting groove. A slot is opened on one side of the turntable 632, and the side wall of the slot of the turntable 632 has a bevel formed by machining. The outer wall of the connecting rod 633 is fixedly connected to the outer wall of the positioning sleeve 62. A limiting block 634 is fixed on the side wall of the connecting rod 633 to limit... The outer wall of block 634 has a curved edge formed by machining. Along with the connection of positioning sleeve 62 and storage sleeve, the insertion rod 633 on moving mold 5 is inserted into the interior of fixed block 631, causing the limiting block 634 on insertion rod 633 to press turntable 632, causing turntable 632 to rotate clockwise. The limiting block 634 can be moved into the interior of turntable 632. At the same time, through the setting of torsion spring, turntable 632 is reset and limited, fixing positioning sleeve 62 and storage sleeve together.

[0029] In this embodiment, as Figure 4 As shown, the interior of the turntable 632 is hollow. The shaft end of the turntable 632 extends to the outside of the fixing block 631 and is fixedly connected to a knob. A torsion spring is sleeved on the shaft end of the turntable 632. The turntable 632 can be rotated by manually turning the knob. Using the weight of the stainless steel pipe, the stainless steel pipe and the shelf 63 move down together and separate, making it convenient for the user to take out the stainless steel pipe and avoiding the stainless steel pipe from getting stuck in the mold, which would cause inconvenience.

[0030] In this embodiment, as Figure 1 As shown, the hydraulic lifting plate 3 includes a transmission rod 31 and a protective plate 32. One side of the transmission rod 31 is hinged to the side wall of the hydraulic lifting plate 3. Two sets of transmission rods 31 are symmetrically arranged about the axis of the hydraulic lifting plate 3. The bottom end of the transmission rod 31 is hinged to the protective plate 32, which is made of acrylic material. The shaft end of the protective plate 32 is hinged to the molding machine body. Two sets of protective plates 32 are symmetrically arranged about the axis of the molding machine body 1. When the hydraulic lifting plate 3 rises, the transmission rod 31 pulls the protective plate 32 to rotate clockwise, closing the protective plate 32 and isolating the end face of the user's operation to prevent liquid from splashing everywhere.

[0031] In this embodiment, as Figure 1As shown, the collection component 7 includes a collection chamber 71 and a permeation mesh 72. The outer wall of the collection chamber 71 is fixedly connected to the inner wall of the molding machine body 1. The permeation mesh 72 is opened in the top wall of the molding machine body 1. A filter mesh 73 is fixed in the inner wall of the collection chamber 71. The bottom end of the filter mesh 73 is connected to a collection funnel 74. The bottom end of the collection funnel 74 is connected to a conveying pipe 75. When liquid seeps out, it will be sent into the collection chamber 71 through the permeation mesh 72 on the top wall of the molding machine body 1. After being filtered once by the filter mesh 73, it is finally collected through the collection funnel 74 and discharged through the conveying pipe 75.

[0032] In this embodiment, as Figure 1 As shown, the top wall of the molding machine body 1 and the permeation mesh 72 are arranged in a concave structure. The permeation mesh 72 and the filter mesh 73 are arranged horizontally. As the splashed liquid is blocked by the protective plate 32, the liquid flows downward to the top of the molding machine body 1 due to its own gravity. Through the concave arrangement, the liquid automatically flows through the internal concave inclined surface to the permeation mesh 72 for liquid guidance, which facilitates liquid recovery.

[0033] The method of use and advantages of this invention: The stainless steel pipe fitting is formed using the following equipment, and the working process is as follows:

[0034] like Figures 1 to 6 As shown, the staff can manually place the stainless steel pipe fittings on the storage sleeve. As the hydraulic lifting plate 3 moves down, the hydraulic lifting plate 3 drives the positioning plate 61 to move down as well, causing the positioning sleeve 62 and the storage sleeve to clamp the two ends of the stainless steel pipe fittings. At this time, the plug rod 633 on the moving mold 5 is inserted into the interior of the fixing block 631, causing the limiting block 634 on the plug rod 633 to press the turntable 632, causing the turntable 632 to rotate clockwise. This can move the limiting block 634 into the interior of the turntable 632. At the same time, through the setting of the torsion spring, the turntable 632 is reset and limited, fixing the positioning sleeve 62 and the storage sleeve together.

[0035] Then, as the hydraulic lifting plate 3 continues to move downward, the positioning sleeve 62 moves downward through the telescopic spring rod 64 until the fixed mold 2 and the moving mold 5 clamp and fix the stainless steel pipe. Through the through holes on the two sets of guide rods 4, the external hydraulic pipe can be inserted into the stainless steel pipe for internal high-pressure forming.

[0036] After the operation is completed, the external hydraulic pipeline is removed. As the hydraulic lifting plate 3 moves upward, the stainless steel pipe is moved out of the fixed mold 2 by the fixed positioning sleeve 62 and the storage sleeve. At this time, the knob can be turned manually to drive the turntable 632 to rotate. Using the weight of the stainless steel pipe itself, the stainless steel pipe and the storage plate 63 move down together to separate, making it convenient for the user to take out the stainless steel pipe and avoiding the stainless steel pipe from getting stuck in the mold, which would cause inconvenience.

[0037] Secondly, with the hydraulic lifting plate 3 in place, when the hydraulic lifting plate 3 rises, the transmission rod 31 pulls the protective plate 32 to rotate clockwise, closing the protective plate 32 and isolating the end face of the user's operation to prevent liquid from splashing everywhere. Then, when the liquid seeps out, it will be sent into the collection chamber 71 through the permeation mesh 72 on the top wall of the molding machine body 1, filtered once through the filter screen 73, and finally collected through the collection funnel 74 and discharged through the conveying pipe 75.

[0038] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of the present invention is defined by the appended claims and their equivalents.
