[0029] See also Figures 1 to 7 The present invention provides a technical solution: a thin-walled stainless steel corrugated pipe compression wave forming device, comprising a corrugator body 1, a hydraulic telescopic rod 2 is fixed to the top wall of the corrugator body 1, an upper template 3 is fixed to the bottom end of the transmission end of the hydraulic telescopic rod 2, and a driving component 4 is fixed to the side wall of the upper template 3;

[0030] The hydraulic telescopic rod 2 is connected to the external hydraulic pump through a hydraulic pipe, and an operating component 6 is horizontally arranged below the upper template 3;

[0031] A transmission belt 7 is horizontally provided at one end of the corrugator body 1, and a plurality of push blocks 8 are fixed on the surface of the transmission belt 7, and the push blocks 8 are horizontally distributed at equal intervals. When the device is started, the transmission belt 7 is driven by an external motor, and the plurality of push blocks 8 on the transmission belt 7 are used to push the metal rod to the movable seat 611 in the operating component 6 for loading, so that the upper membrane plate can be conveniently pressed and formed by the metal rod through the hydraulic telescopic rod 2, and the tooth plate 42 and the rotating gear in the driving component 4 are used to adjust the position of the adsorption plate 432 to adsorb metal debris and waste.

[0032] In this embodiment, Figure 2 and Figure 3 As shown, the driving assembly 4 includes a connecting rod 41 and a transmission gear 43. One end of the connecting rod 41 is fixedly connected to the side wall of the upper template 3. A toothed plate 42 is fixed to the bottom end of the connecting rod 41.

A through groove 44 is provided on the side wall of the wave pressing machine body 1, and the through groove 44 is slidably matched with the connecting rod 41.

[0033] A cleaning assembly 5 is fixed inside the corrugator body 1. As the upper template 3 moves downward, the upper template 3 drives the tooth plate 42 through the through slot 44 via the connecting rod 41 on the side wall to move downward, thereby using the tooth plate 42 to drive the transmission gear 43 to rotate, thereby driving the cleaning assembly 5 to operate;

[0034] In this embodiment, Figure 2 、 Figure 3 and Figure 4As shown, the transmission gear 43 includes a screw slide 431, the screw shaft end of the screw slide 431 is fixedly connected to the shaft end of the transmission gear 43, and an adsorption plate 432 is fixed to the bottom of the slider end of the screw slide 431.

As the transmission gear 43 rotates, the transmission gear 43 drives the screw on the screw slide 431 to rotate, pushing the slider to drive the adsorption plate 432 to move forward, causing the adsorption plate 432 to be moved out of the wave pressing machine body 1, so that when the metal waste is blown off, the metal waste can be adsorbed and processed, and the adsorption plate 432 is set as a magnet;

[0035] In this embodiment, Figure 3 、 Figure 4 and Figure 6 As shown, the cleaning assembly 5 includes an air outlet pipe 51, the side wall of which is fixedly connected to the inner wall of the wave compressor body 1, an air outlet hole 52 is opened inside the air outlet pipe 51, the rear end of the air outlet pipe 51 is connected to an air supply pipe 53, and the end of the air supply pipe 53 is connected to an air pump 54;

[0036] A rectangular protrusion is fixed on the side wall of the tooth plate 42. As the air pump 54 continuously outputs gas, the gas is sent into the outlet pipe 51 through the output pipe. The outlet holes 52 in the outlet pipe 51 are used to blow away the metal scraps on the metal pipe on the surface of the lower template 62 and are adsorbed and recovered by the adsorption plate 432.

[0037] In this embodiment, Figure 3 and Figure 6 As shown, the gas pipe 53 includes a control panel 531. The inner wall of the control panel 531 is sleeved with the gas pipe 53. A fixing column 532 is inserted into the control panel 531. An adjusting rod 533 is sleeved inside the fixing column 532. A thin rod 534 is fixed to the front end of the adjusting rod 533. A blocking block 535 is fixed to the front end of the thin rod 534. The outer contour of the blocking block 535 matches the inner contour of the fixing column 532.

[0038] The top of the adjusting rod 533 is a machined arc-shaped edge, and the adjusting rod 533 and the rectangular protrusion on the tooth plate 42 are arranged horizontally. As the tooth plate 42 moves downward, the rectangular protrusion on the tooth plate 42 contacts the adjusting rod 533, causing the adjusting rod 533 to move forward. The adjusting rod 533 pushes the blocking block 535 toward the inside of the fixed column 532 through the thin rod 534, thereby unblocking the air outlet 52, allowing high-speed gas to be sent into the air outlet pipe 51 through the air supply pipe 53 and discharged through the air outlet 52, blowing out the metal scraps on the metal pipe on the surface of the lower template 62, and the material is adsorbed and recovered by the adsorption plate 432;

[0039] In this embodiment, Figure 1 and Figure 2 As shown, the operating table 61 includes a movable seat 611, the outer wall of the movable seat 611 is slidably arranged with the side wall of the wave pressing machine body 1, and two movable seats 611 are symmetrically arranged about the axis of the operating table 61. The side wall of the wave pressing machine body 1 is provided with a sliding groove that is slidably matched with the movable seat 611, and a through hole 612 is provided inside the movable seat 611. A strong spring is fixed in the inner wall of the through hole 612, and a limit block 613 is fixed at the bottom end of the strong spring. The bottom end of the movable seat 611 is fixedly connected with a reset spring 614, and the bottom end of the reset spring 614 is aligned with the bottom of the operating table 61 The upper template 3 is fixedly connected to the wall. When the operation is completed, the hydraulic telescopic rod 2 drives the upper template 3 to move upward, and the moving seat 611 drives the metal rod away from the lower template 62 through the return spring 614. At this time, the transmission belt 7 is started, and the push plate on the transmission belt 7 continues to push the new metal rod. At this time, the new metal rod enters through the through hole 612 of the moving seat 611, squeezing the processed metal rod, causing the processed metal rod to be pushed toward the left end, and squeezing the limit block 613, and the processed metal rod is moved out through the through hole 612 in the moving seat 611 at the left end for unloading, which is convenient for the use of the device.

[0040] The use method and advantages of the present invention: The working process of the wave forming equipment for thin-walled stainless steel corrugated pipe is as follows:

[0041] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 and Figure 7 As shown, when the device is in use, the transmission belt 7 pushes the metal rod into the through-hole 612 in the movable seat 611 through the push block 8. As the metal rod continues to move, the limit block 613 is squeezed, so that the limit block 613 moves inward through the telescopic spring to clamp the metal rod. Then, as the push block 8 continues to push, the metal rod is pushed between the two movable seats 611. At this time, as the hydraulic telescopic rod 2 is activated, the upper template 3 is pushed downward, pushing the metal rod downward and squeezing it with the lower template 62 to form the pressing plate. At the same time, as the metal rod moves downward, the movable seat 611 is displaced and the return spring 614 is squeezed.

[0042] Then, as the upper template 3 moves downward, the rear end of the upper template 3 drives the tooth plate 42 to move downward, pushing the transmission gear 43 to rotate, and the transmission gear 43 drives the screw on the screw slide 431 to rotate, pushing the slider to drive the adsorption plate 432 to move forward, so that the adsorption plate 432 is moved out of the wave pressing machine body 1. Figure 3As shown, as the tooth plate 42 moves downward, the rectangular protrusion on the tooth plate 42 contacts the adjustment rod 533, causing the adjustment rod 533 to move forward. The adjustment rod 533 pushes the blocking block 535 toward the inside of the fixed column 532 through the thin rod 534, thereby unblocking the air outlet 52. The high-speed gas is sent into the air outlet pipe 51 through the air supply pipe 53 and discharged through the air outlet 52, blowing out the metal waste on the metal pipe on the surface of the lower template 62, and the material is adsorbed and recovered by the adsorption plate 432.

[0043] Finally, when the operation is completed, the upper template 3 is driven to move upward by the hydraulic telescopic rod 2, and the moving seat 611 drives the metal rod away from the lower template 62 through the return spring 614. At this time, the transmission belt 7 is started, and the push plate on the transmission belt 7 continues to push the new metal rod. At this time, as described above, the new metal rod enters through the through hole 612 of the moving seat 611, squeezes the processed metal rod, causing the processed metal rod to be pushed toward the left end, and squeezes the limit block 613, and moves the processed metal rod out through the through hole 612 in the moving seat 611 at the left end for unloading, which is convenient for the use of the device.
