Description

Technical Field

[0001] The utility model relates to the technical field of stainless steel pipe forming and processing, in particular to a stainless steel pipe stamping and forming machine. Background Art

[0002] Stainless steel pipe stamping is a manufacturing process that processes stainless steel pipes into specific shapes, such as punching steel pipes into squares using a mold on a stamping machine. However, in actual processing work, we found that the steel pipe forming mold is fastened to the machine with bolts, and it is fastened with multiple bolts. Moreover, due to the limitations of the small space inside the machine, the disassembly and assembly work will be subject to many obstacles. For example, on a machine with upper and lower molds, the installation of the upper mold requires the user to lift the mold all the time until the bolts are inserted and positioned before it can be released. During this process, the lifting action is prone to trembling, resulting in the screw holes on the mold being difficult to accurately align with the screw holes on the machine, making it difficult to insert the bolts quickly. The user's lifting hands will also become tired, making it difficult to maintain the lifting action, wasting a lot of time and reducing the installation speed and efficiency of the mold.

The output end of the electric push rod 18 is fixed on the slider 14. When working, the electric push rod 18 will push the slider 14 to slide on the guide rail formed by the combination of the two slide rails 13, and then the lower mold 17 will move along. The user places the workpiece into the notch on the lower mold 17, and then the electric push rod 18 controls the workpiece to be pulled back into the machine. After that, the electric push rod 2 19 drives the upper mold 6 to move down and close the mold with the lower mold 17 to stamp the steel pipe. In this way, automatic feeding can be realized and the steel pipe stamping can be improved. The speed and efficiency of molding also improves work safety and provides convenience for users. Among them, the installation method of the lower mold 17 and the upper mold 6 is roughly the same. First, the block 2 16 is inserted into the slot 2 15, and then the slider 14 is inserted from one side into the guide rail composed of two slide rails 13. At the same time, the protruding parts on both sides of the block 2 16 and the protruding parts on both sides of the slider 14 will be stuck on the inner side of the slide rail 13.

In this way, the assembly work of the lower mold 17 is completed quickly, which provides convenience for the user's installation work.

[0033] A housing 20 is fixedly mounted on the top of the base 1, and the clamping female component 2 and the upper mold 6 are both located inside the housing 20. An electric push rod 2 19 is fixedly mounted on the top of the housing 20, and the output end of the electric push rod 2 19 passes through the interior of the housing 20 and is fixedly mounted on the clamping female component 2.

[0034] Specifically, the setting of the electric push rod 2 19 and the casing 20, the casing 20 is the outer shell of the machine, which can cover the upper mold 6 and the movable cavity 7 and other components, and play a protective role to prevent external foreign objects from damaging the internal components of the machine, ensure the normal operation of the machine, and extend the service life of the machine. The output end of the electric push rod 2 19 is connected to the clamping mother part 2, so that the electric push rod 2 19 can control and drive the clamping mother part 2 and the upper mold 6 to move downward, and the upper mold 6 and the lower mold 17 are combined to complete the forming process of the steel pipe.

[0035] A door panel 21 is movably mounted on one side of the housing 20 , and a notch is formed on one side of the door panel 21 to match the lower mold 17 .

[0036] Specifically, the door panel 21 is provided as a door stop, which can block the side of the casing 20 facing the user without affecting the processing and forming of the workpiece, preventing foreign objects from entering the machine and causing damage to the workpiece and the machine, and also preventing foreign objects in the machine from popping out and injuring the staff, thereby improving the user's work safety.

[0037] The specific working principle is as follows: First, the lower mold and the upper mold adopt a similar installation structure, and both use mother-and-child parts for early positioning of the installation work, so that the bolts can be quickly inserted and installed to improve the installation speed of the mold. The difference is that the mother-and-child parts on the lower mold can be used as sliders and slide rails, that is, the child parts are slidably installed in the mother parts as sliders, that is, in the slide rails, so as to meet the actual work needs. The following article describes the disassembly and assembly process of the above molds. When disassembling, loosen and remove the fastening bolts 11. It needs to be explained The upper mold 6 is also fastened to the clamping mother part 2 with only one fastening bolt 11, and the clamping mother part 2 is installed on the electric push rod 2 19, so that the electric push rod 2 19 can drive the upper mold 6 to move up and down during operation. After removing the fastening bolt 11, the upper mold 6 is held together with the clamping sub-part 3 and slides out from the clamping mother part 2 to one side. In this way, without the restriction of the clamping mother part 2, the clamping block 1 5 can be moved out of the clamping slot 1 4 by removing the upper mold 6 downward, and finally the upper mold 6 can be removed. Figure 4-5As shown, the card block 15 is the same as the card connection sub-component 3, and a part of both sides is stuck in the card connection mother component 2, so that the card connection sub-component 3 and the card block 15 will not fall vertically. Before removing the card block 15 from the card slot 14, press the card pins 8 on both sides, and then the card pins 8 will turn on the shaft 9 and twist the torsion spring 10 at the same time. The card pin 8 rotates in the movable cavity 7. After that, the end of the card pin 8 that was originally stuck on the inner side of the card block 15 will be separated from the card block 15, and then the card block 15 can be It can be moved out of the card slot 4, so as to remove the upper mold 6. During installation, the upper mold 6 is controlled to insert the card block 5 into the card slot 4. Among them, the card block 5 will first squeeze the end corresponding to the card pin 8 to move out of the card slot 4 and enter the active cavity 7 until the groove on the card block 5 is aligned with the end corresponding to the card pin 8. At this time, the card pin 8 is driven to reset under the reset action of the torsion spring 10, so that the end of the card pin 8 will be stuck in the card block 5, that is, in the groove on the card block 5. Figure 4-5After that, the clamping sub-component 3 is inserted into the clamping mother component 2 from one side, wherein the protruding parts on both sides of the clamping sub-component 3 will overlap the inner wall of the clamping mother component 2, and similarly, the protruding parts on both sides of the clamping block 5 will also overlap the inner wall of the clamping mother component 2, so that the upper mold 6 and the clamping sub-component 3 will not fall vertically. Then the user adjusts the bolt holes on the clamping sub-component 3 to align with the bolt holes on the clamping mother component 2, and finally inserts the fastening bolts 11 and tightens it to complete the installation of the upper mold 6. The entire disassembly and assembly process takes extremely short time and is fast. The disassembly and assembly of the upper mold 6 can be completed in a short time, thereby improving the efficiency of the disassembly and assembly of the upper mold 6. In this way, the user can quickly complete the replacement of different types of molds, thereby meeting Different processing requirements provide convenience for the user's work. The disassembly and assembly of the lower mold, that is, the lower mold 17 is similar to the upper mold 6. When disassembling, directly control the lower mold 17 to drive the slider 14 to move out of the guide rail formed by the two slide rails 13. When installing, control the lower mold 17 to drive the slider 14 to insert into the guide rail formed by the two slide rails 13, and then adjust the lower mold 17 to a suitable working position. Then, install and fix the slider 14 on the electric push rod 18, and use the electric push rod 18 to drive the slider 14 and the lower mold 17 to work and move. When the machine is working, put the pipe fittings to be stamped into the groove on the lower mold 17. At this time, the lower mold 17 is located outside the machine. This method can be conveniently used. The user can discharge the material and realize automatic feeding, and then start the electric push rod 18 to pull the slider 14 into the base 1, that is, the casing 20, until the lower mold 17 is located directly below the upper mold 6 and stops. At this time, the upper mold 6 will move down under the drive of the electric push rod 2 19, and then the upper mold 6 and the lower mold 17 are molded together to punch the pipe into a square or other shape by extrusion. It should be noted that this requires the use of different types of molds. After the pipe is formed, the upper mold 6 moves up and separates under the drive of the electric push rod 2 19, and then the electric push rod 18 sends the lower mold 17 out of the machine. The user removes the finished workpiece and puts the unprocessed pipe on the lower mold 17, and then repeats the above steps. It can realize automatic stamping work, provide assistance and convenience for the user's work, so by setting up a parent-child structure that can be plugged into each other, the child part is first inserted into the mother part during the installation work, which can realize the positioning of the mold, eliminating the user's action of lifting the mold, speeding up the speed of bolt plugging and tightening, and improving the speed and efficiency of mold installation, providing assistance and convenience for the user's mold disassembly and assembly work, so by setting up a parent-child structure that can be plugged into each other, the child part is first inserted into the mother part during the installation work, which can realize the positioning of the mold, eliminating the user's action of lifting the mold, speeding up the speed of bolt plugging and tightening, and improving the speed and efficiency of mold installation, providing assistance and convenience for the user's mold disassembly and assembly work.
