The base 1 and the clamping assembly 2 are connected by a spring assembly 6, and a noise reduction lifting device 4 is installed outside the base 1, the clamping assembly 2 and the fixing assembly 3. The mounting plate 5 and the noise reduction lifting device 4 are connected by a temporary storage device 7.

[0023] Specifically, the noise reduction lifting device 4 includes a connection box 41, a moving shell 42, sound-absorbing cotton 43, a moving plate 44 and a moving assembly 45. A connection box 41 is installed on one side of the base 1 close to the mounting plate 5. A moving plate 44 is arranged on one side of the connection box 41. A moving shell 42 is installed above the moving plate 44 and at a position outside the base 1, the clamping assembly 2 and the fixing assembly 3.

[0024] By adopting the above technical solutions, the die can perform a certain noise reduction treatment on the noise generated during processing through the cooperation of structures such as the moving shell 42 and the sound-absorbing cotton 43, thereby reducing the possibility of adverse effects on surrounding personnel.

[0025] Specifically, the noise reduction lifting device 4 further includes an electric lifting rod 46, and an electric lifting rod 46 is installed on one side of the connection box 41 close to the mounting plate 5.

[0026] By adopting the above technical solution, the staff can adjust the height of structures such as the base 1 through the electric lifting rod 46 when needed, so as to better meet the working needs in different situations.

[0027] Specifically, the moving component 45 includes a moving block 451, a lead screw 452 and a knob 453. A knob 453 is arranged on one side of the connection box 41. A lead screw 452 is installed on the side of the knob 453 close to the connection box 41. A moving block 451 is installed on the moving plate 44 at a position outside the lead screw 452 and inside the connection box 41.

[0028] By adopting the above technical solution, the staff can adjust the position of structures such as the moving shell 42 through the cooperation of structures such as the lead screw 452 and the moving block 451 when needed, so as to select whether to carry out noise reduction work.

[0029] When this embodiment is in use, when the staff needs to use the mold, the mounting plate 5 is installed at the working position through screws, and then the electric lifting rod 46 in the noise reduction lifting device 4 is started to adjust the height of structures such as the connection box 41 and the base 1. Then, the fixing component 3 is adjusted, and the knob 453 in the moving component 45 is rotated, so as to drive the lead screw 452 to rotate. The lead screw 452 is in threaded connection with the moving block 451, and the outside of the moving block 451 is closely attached to the inside of the connection box 41. Therefore, the lead screw 452 drives the moving block 451 to move, and then drives the moving shell 42 to move to the outside of the clamping component 2 and the fixing component 3 through the moving plate 44. Then, the galvanized pipe is inserted into the clamping component 2, and the punch component 8 on the base 1 is operated to cooperate with the clamping component 2 and the fixing component 3 to carry out upsetting processing on the galvanized pipe. During the processing, the sound-absorbing cotton 43 can carry out noise reduction treatment on the noise, and the spring component 6 plays a role of buffering and resetting.

[0030] Embodiment 2

[0031] The difference between this embodiment and Embodiment 1 is that the temporary storage device 7 includes a storage box 71, a pressing plate 72, a rotating plate 73 and a screw rod 74. A storage box 71 is installed between the mounting plate 5 and the electric lifting rod 46. A screw rod 74 is installed at the top of the storage box 71 at a position far from the connection box 41 of the knob 453 through threads. A rotating plate 73 is installed above the screw rod 74. A pressing plate 72 is installed below the screw rod 74 and inside the storage box 71 through a bearing.

[0032] By adopting the above technical solution, the mold can temporarily store the galvanized pipe through the storage box 71 when needed, and the mold can fix the galvanized pipe in the storage box 71 through the cooperation of structures such as the screw rod 74 and the pressing plate 72 when needed, so as to better meet the working needs in different situations.

[0033] Specifically, the temporary storage device 7 further includes a rubber layer 75, and the rubber layer 75 is installed below the pressing plate 72.

[0034] By adopting the above technical solution, the mold can prevent the pressing plate 72 and the galvanized pipe from colliding and damaging each other through the rubber layer 75, thus better meeting the needs of the staff and ensuring the normal progress of the work.

[0035] When in use in this embodiment, when it is necessary to temporarily store the galvanized pipe, the galvanized pipe is placed in the storage box 71 in the temporary storage device 7, and the rotating plate 73 is rotated, thereby driving the screw rod 74 to rotate. The screw rod 74 is threadedly connected to the storage box 71, and the screw rod 74 is connected to the pressing plate 72 through a bearing, and the pressing plate 72 is close to the storage box 71. Therefore, the screw rod 74 drives the pressing plate 72 and the rubber layer 75 below it to descend, and then presses the galvanized pipe, and the temporary storage is completed.

[0036] In the present utility model, the structures and principles of the base 1, the clamping assembly 2 composed of a clamping plate, a groove and a placement hole, the fixing assembly 3 composed of a fixing plate, a baffle, a wedge-shaped ejector rod, a positioning groove, a top block, a through hole, a buffer rod, an arc-shaped pressing plate, a buffer groove, a buffer spring and a screw rod, the spring assembly 6 composed of a sliding groove, a slider, a sliding rod and a return spring, and the punch assembly 8 composed of a fixing seat, a mounting plate, a punch and a cylinder have been disclosed in the molds of various pier products disclosed in Chinese Patent Application No. 202222843949.0. Its working principle is that during work, the pipe fitting is placed in the placement hole. When stamping, the cylinder switch is started, and the piston of the cylinder drives the punch to move through the mounting plate, thereby pushing the pipe fitting. The pipe fitting drives the clamping plate to move leftward, and the moving clamping plate drives the top block to move. The top block can drive the top block to move through the mutual cooperation of the wedge-shaped ejector rod and the through hole. The top block drives the arc-shaped pressing plate to press and fix the pipe fitting through the buffer rod. At the same time, the punch punches the pipe fitting to form a pier. When the cylinder drives the punch to return, the return spring can drive the clamping plate to buffer and reset through the slider, so that the wedge-shaped ejector rod moves out of the through hole.

[0037] Working principle and usage process of the utility model: When a worker needs to use the mold, the mounting plate 5 is installed at the working position through screws, and then the electric lifting rod 46 in the noise reduction lifting device 4 is started, so as to adjust the heights of structures such as the connection box 41 and the base 1. Then, the fixing component 3 is adjusted, and the knob 453 in the moving component 45 is rotated, thereby driving the screw rod 452 to rotate. The screw rod 452 is in threaded connection with the moving block 451, and the outer side of the moving block 451 is closely attached to the inner side of the connection box 41. Therefore, the screw rod 452 drives the moving block 451 to move, and then drives the moving shell 42 to move to the outside of the clamping component 2 and the fixing component 3 through the moving plate 44. Then, the galvanized pipe is inserted into the clamping component 2, and the punch component 8 on the base 1 is operated to cooperate with the clamping component 2 and the fixing component 3 to perform upsetting processing on the galvanized pipe. During the processing, the sound-absorbing cotton 43 can reduce the noise, and the spring component 6 plays a role of buffering and resetting; When the galvanized pipe needs to be temporarily stored, the galvanized pipe is placed in the storage box 71 in the temporary storage device 7, and the rotating plate 73 is rotated, thereby driving the screw rod 74 to rotate. The screw rod 74 is in threaded connection with the storage box 71, the screw rod 74 is in bearing connection with the pressing plate 72, and the pressing plate 72 is closely attached to the storage box 71. Therefore, the screw rod 74 drives the pressing plate 72 and the rubber layer 75 below it to descend, and then presses the galvanized pipe, and the temporary storage is completed.
