Description

Technical Field

[0001] The utility model relates to the technical field of steel pipe processing equipment, in particular to a lined stainless steel connector stamping device. Background Art

[0002] Lined stainless steel pipe is a composite pipe material, which is made of carbon steel pipe as the base pipe and is compounded with thin-walled stainless steel pipe inside. This structure combines the corrosion resistance of stainless steel material and the mechanical strength of carbon steel pipe, and is suitable for a variety of fluid transportation systems, such as water supply, drainage, gas, heat, etc. When using, the lined stainless steel pipe needs to be connected through a connecting joint. When the connecting joint is processed, its end needs to be radially enlarged to make the connection between the steel pipe and the joint more tightly fixed. In the existing technology, when the connecting joint is stamped and expanded, a clamp or other fixing device is usually used to fix the connecting joint to ensure that it does not move during the expansion process. Then the connecting joint is placed in the expansion machine, and the machine is started to expand. The expanding machine will expand the connecting joint through the expanding die to increase its outer diameter.

[0003] However, some existing stamping and expanding equipment can only perform stamping and expanding processing on one end of the connecting joint at a time. The connecting joint needs to be clamped multiple times, which is a cumbersome process. In addition, the adaptability to connecting joints of different sizes is relatively poor, and it cannot meet the stamping and expanding processing requirements of connecting joints of different sizes. Moreover, the existing stamping and expanding equipment is not stable enough during operation, which makes the processing accuracy of the connecting joint low, affecting the working efficiency of the equipment. Utility Model Content

[0004] In view of the above-mentioned technical problems, the utility model provides a lined stainless steel connector stamping device.

[0009] Description: The power motor drives the rotating gear to rotate, and the meshing action of the rotating gear and the rack is used to make the punch rod drive the punch to move along the guide hole to expand the inner stainless steel connector.

[0010] Furthermore, an operating hole is provided on the limit seat, and each clamping block is equidistantly distributed on the inner side wall of the operating hole. A pushing block is provided at both ends of each clamping block.

[0011] Description: When in use, the pneumatic push rod is used to push the inner gear ring to rotate inside the limit seat. Since the connecting gear is engaged with the inner gear ring, each driving rod drives the corresponding arc-shaped pressure block to rotate. The arc-shaped pressure block squeezes the push block on the clamping block, so that the clamping blocks are close to each other, thereby clamping and fixing the inner stainless steel connector.

[0012] Furthermore, a protective sleeve is provided on the side of the mounting seat away from the limiting assembly and is sleeved on the outside of the punching rod, and a guide rod movably connected to the punching rod is provided inside the protective sleeve;

[0013] Description: By providing a protective sleeve and a guide rod, it is helpful to improve the stability of the punching rod when it moves inside the guide hole, thereby improving the accuracy of the punching of the lined stainless steel connector.

[0014] Furthermore, the punch is movably sleeved at the end of the punching rod, the punch end is provided with a baffle plate abutting against the punching rod, the baffle plate is provided with a positioning sleeve movably plugged into the punching rod, and a positioning groove is provided on the inner wall of the positioning sleeve; a fixed ball rod capable of being engaged with the positioning groove is slidably engaged inside the punching rod, and a compression spring abutting against the fixed ball rod is provided inside the punching rod;

[0015] Description: By arranging the movable sleeve of the punch at the end of the punch rod, when the positioning sleeve is inserted into the punch rod, the fixed ball rod is engaged with the positioning groove on the positioning sleeve under the action of the compression spring, so that the utility model can be used to facilitate the replacement of punches of different sizes during use, thereby realizing the stamping processing of lined stainless steel connectors of different sizes.

[0016] Furthermore, the clamping block is slidably engaged with the inner side wall of the operating hole through a clamping block, and a return spring abutting against the clamping block is provided inside the operating hole;

[0017] Note: The reset spring is provided to facilitate the quick separation of the clamping block and the lined stainless steel connector.

[0018] Furthermore, the limit seat is rotatably connected to the workbench through the rotating disk, and the end surface of the workbench is threadedly connected with a locking screw that can be connected to the rotating disk;

[0019] Description: After the stamping and flaring of one end of the lined stainless steel connector is completed, the other end of the lined stainless steel connector can be stamped and flared by rotating the limit seat, so that when the utility model is used, only one clamping operation needs to be performed on the lined stainless steel connector, thereby improving work efficiency.

[0020] The working principle of this utility model is:

[0021] When in use, the stainless steel lining connector to be expanded is placed inside the operating hole, and the position of the stainless steel lining connector is adjusted, and then the pneumatic push rod is used to push the inner gear ring to rotate inside the limit seat. Since the connecting gear is meshed with the inner gear ring, each driving rod drives the corresponding arc pressure block to rotate, and the arc pressure block squeezes the pushing block on the clamping block, so that each clamping block approaches each other, clamps and fixes the stainless steel lining connector, and locks the rotating disk with the locking screw; then, the mounting seat is moved on the workbench by rotating the positioning screw, and the punch is abutted against the stainless steel lining connector, at this time, the rotating gear is driven to rotate by the power motor, and the meshing action of the rotating gear and the rack is used to make the punch rod drive the punch to move along the guide hole, and one end of the stainless steel lining connector is punched and expanded; finally, the limit seat is rotated, and the locking screw is used to lock the rotating disk again, and the other end of the stainless steel lining connector is punched and expanded.

[0022] Compared with the prior art, the beneficial effects of the present invention are embodied in the following aspects:

[0023] First, the utility model has a reasonable structural design and is easy to operate. The limiting assembly is used to clamp and fix the lining stainless steel connector, and the punch is driven to move by the punch rod to perform punching and expanding processing on the end of the lining stainless steel connector. Under the joint action of the guide hole and the guide rod, the punch rod always keeps moving smoothly, thereby improving the processing accuracy of the lining stainless steel connector during punching and expanding.

[0024] Secondly, the utility model rotates and clamps the limit seat on the workbench, so that when the utility model is used, only one clamping operation is required for the lining stainless steel connector to complete the stamping and expanding processing of both ends, which not only improves the work efficiency but also avoids the error problem caused by multiple clamping of the lining stainless steel connector;

[0025] Third, the punch of the present invention is movably connected to the end of the punching rod, which is convenient for replacing punches of different sizes, so that the present invention can perform punching and expanding processing on lined stainless steel connectors of different sizes, thereby improving the scope of application.
