DETAILED DESCRIPTION

[0024] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0025] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.

[0026] In one embodiment, see Figure 1 , Figure 2 and Figure 3 A stainless steel pipe continuous stamping machine comprises a stamping platform 2, a support frame 1 is fixed on the top of the stamping platform 2, a hydraulic cylinder 5 is fixed on the top of the support frame 1, a lifting plate 6 is installed on the output end of the hydraulic cylinder 5, the lifting plate 6 is located between the support frame 1 and the stamping platform 2, wherein a punch 10 for stamping the stainless steel pipe is fixed at the bottom of the lifting plate 6, a fixed frame 9 is fixed on the top of the stamping platform 2, the fixed frame 9 is fixedly connected to a limiting column 8, a supporting mechanism 3 is provided on the outside of the limiting column 8, the supporting mechanism 3 is used to support the stainless steel pipe from the inside of the stainless steel pipe, a supporting seat 7 for supporting the stainless steel pipe is slidably connected to the surface of the stamping platform 2, the supporting seat 7 is slidably connected to the stamping platform 2, wherein the supporting seat 7 is connected to a driving mechanism 4, and the driving mechanism 4 is used to drive the supporting seat 7 to move continuously.

[0027] In this embodiment, when the punching machine continuously punches the stainless steel pipe, the stainless steel pipe is placed on the surface of the support seat 7, and the stainless steel pipe is supported by the support seat 7, wherein the surface of the support seat 7 can be provided with an arc groove adapted to the stainless steel pipe. After the stainless steel pipe is placed, the hydraulic cylinder 5 is started, and the hydraulic cylinder 5 drives the lifting plate 6 to move downward. While the lifting plate 6 moves downward, it first drives the support seat 7 forward a certain distance through the driving mechanism 4, and then drives the stainless steel pipe forward a certain distance. During the advancement of the stainless steel pipe, the limit column 8 will be inserted into the interior of the stainless steel pipe from the end of the stainless steel pipe. When the stainless steel pipe moves a certain distance, the driving mechanism 4 stops driving the support seat 7 to move. Then, the lifting plate 6 continues to descend while supporting the stainless steel pipe from the inside of the stainless steel pipe through the supporting mechanism 3. After the supporting mechanism 3 has supported the stainless steel pipe, the lifting plate 6 can punch the stainless steel pipe through the punch 10 while moving downward. The setting of the supporting mechanism 3 can, on the one hand, play a fixing role for the stainless steel pipe, thereby ensuring the stability of the stainless steel pipe during the punching process; on the other hand, it can play a supporting role for the top of the stainless steel pipe, so that the force inside and outside the stainless steel pipe is uniform, effectively avoiding the local deformation of the stainless steel pipe due to the external force when the punch 10 punches the stainless steel pipe, thereby ensuring the quality of the finished product of the stainless steel pipe.

[0028] See also Figure 3 and Figure 6The supporting mechanism 3 includes arc-shaped supporting plates 31 arranged on the upper and lower sides of the limiting column 8 and symmetrically distributed. The arc-shaped supporting plates 31 are fixedly connected with supporting rods 33. One end of the supporting rod 33 away from the arc-shaped supporting plate 31 extends into the limiting column 8 and is rotatably connected with a connecting rod 38. The other end of the connecting rod 38 is rotatably connected with a sliding rod 37. The sliding rod 37 is connected with an extrusion component, which is used to extrude the sliding rod 37, so that the arc-shaped supporting plates 31 are away from each other.

[0029] When stamping the stainless steel pipe, the hydraulic cylinder 5 drives the lifting plate 6 to move downward. While the lifting plate 6 moves downward, the sliding rod 37 is squeezed through the extrusion assembly. The sliding rod 37 is squeezed and drives the two support rods 33 away from each other through the connecting rod 38, thereby driving the arc support plates 31 away from each other until the two arc support plates 31 fit against the inner wall of the stainless steel pipe, so that the arc support plates 31 can support the stainless steel pipe from the inside of the stainless steel pipe, effectively improving the stability of the stainless steel pipe during the stamping process, and also avoiding the deformation of the stainless steel pipe during the stamping process.

[0030] See also Figure 2 , Figure 3 and Figure 6 The extrusion assembly includes a slide groove 36 arranged on the surface of the limit column 8, and a trapezoidal block 35 is slidably connected inside the slide groove 36. The trapezoidal block 35 is connected to the inner wall of the slide groove 36 through a first elastic component 34, wherein an extrusion plate 311 for extruding the inclined surface of the trapezoidal block 35 is fixed at the bottom of the lifting plate 6, and one end of the slide rod 37 away from the connecting rod 38 extends into the slide groove 36 and is fixedly connected to the trapezoidal block 35;

[0031] When punching the stainless steel pipe, the hydraulic cylinder 5 is used to drive the lifting plate 6 to move downward. The lifting plate 6 moves downward and drives the extrusion plate 311 to move downward. When the extrusion plate 311 drops to a certain position, the extrusion plate 311 squeezes the inclined surface of the trapezoidal block 35, so that the trapezoidal block 35 drives the slide bar 37 to move horizontally, thereby making the two arc-shaped support plates 31 move away from each other. When the side wall of the extrusion plate 311 fits with the side wall of the trapezoidal block 35, the arc-shaped support plate 31 fits tightly with the inner wall of the stainless steel pipe. Then, the lifting plate 6 continues to move downward and the punch 10 can be used to punch the stainless steel pipe. The stainless steel pipe is stamped, and as the lifting plate 6 continues to move, the degree of squeezing of the trapezoidal block 35 by the squeezing plate 311 does not change. When the stainless steel pipe is stamped, the lifting plate 6 drives the squeezing plate 311 to move upward, and the squeezing plate 311 no longer squeezes the trapezoidal block 35. The trapezoidal block 35 automatically resets under the action of the first elastic component 34. The first elastic component 34 can be a spring, which in turn drives the two arc-shaped support plates 31 to approach each other, thereby releasing the supporting effect of the arc-shaped support plate 31 on the stainless steel pipe, so that the support seat 7 can smoothly drive the stainless steel pipe to move.

[0032] See also Figure 7 The arc-shaped support plate 31 and the support rod 33 are both provided with a punching groove 310, and a baffle 32 is provided inside the punching groove 310. The baffle 32 is connected to the bottom of the punching groove 310 through a second elastic component 39;

[0033] By setting the groove 310, the punch 10 can enter the groove 310 while punching the stainless steel pipe, thereby ensuring the stamping effect, and the punch 10 will squeeze the punched stainless steel pipe sheet into the groove 310. At this time, the first elastic component 34 is in a compressed state. After the stamping is completed, the punch 10 moves to the outside of the groove 310, and the second elastic component 39 releases the elastic potential energy, thereby ejecting the punched stainless steel pipe sheet to the outside of the groove 310 through the baffle 32, which can effectively prevent the punched stainless steel pipe sheet from accumulating inside the groove 310, wherein the second elastic component 39 can be a spring.

[0034] See also Figure 4 and Figure 5 The driving mechanism 4 includes tooth plates 42 fixed on both sides of the support seat 7 and symmetrically distributed, the tooth plates 42 are meshed with gears 41, and the gears 41 are fixedly connected with rotating rods 45, and the top of the stamping platform 2 is fixed with symmetrically distributed limiting plates 46, and the rotating rod 45 passes through the limiting plates 46 and is connected with a rotating assembly, and the rotating assembly is used to drive the rotating rod 45 to rotate in one direction;

[0035] When stamping the stainless steel pipe, the hydraulic cylinder 5 is used to drive the lifting plate 6 to move downward. While the lifting plate 6 moves downward, it first drives the rotating rod 45 to rotate a certain angle through the rotating assembly. The rotating rod 45 drives the gear 41 to rotate a certain angle. While the gear 41 rotates, it engages with the tooth plate 42 to drive the support seat 7 forward a certain distance, and then drives the stainless steel pipe forward a certain distance, so that the punch 10 can connect and stamp the stainless steel pipe, effectively improving the stamping efficiency of the stainless steel pipe.

[0036] See also Figure 5 The rotating assembly includes a rotating disk 47 fixedly connected to the end of the rotating rod 45, and the surface of the rotating disk 47 is provided with symmetrically distributed grooves 48, and the inside of the grooves 48 is rotatably connected with a stopper 49, and the end of the stopper 49 extends to the outside of the groove 48, wherein one side of the stopper 49 is connected to the inner wall of the groove 48 through a third elastic component 410, and the other side of the stopper 49 is connected to the inner wall of the groove 48. The bottom of the lifting plate 6 is fixed with a rack 43 that is symmetrically distributed and can drive the rotating disk 47 to rotate through the stopper 49;

[0037] When stamping the stainless steel pipe, the hydraulic cylinder 5 is used to drive the lifting plate 6 to move downward, and the lifting plate 6 drives the rack 43 to move downward while the lifting plate 6 moves downward. The rack 43 squeezes the stopper 49 through the teeth while the rack 43 moves downward, so that the stopper 49 drives the turntable 47 to rotate, and the turntable 47 drives the gear 41 to rotate through the rotating rod 45, so that the support seat 7 drives the stainless steel pipe to move forward a certain distance. When all the teeth on the rack 43 move to the bottom of the stopper 49, even if the lifting plate 6 continues to move downward, the turntable 47 cannot rotate. This ensures the stability of the support seat 7. When the stainless steel tube is stamped, the lifting plate 6 drives the rack 43 to move upward. Since the block 49 is connected to the inner wall of the groove 48 through the third elastic component 410, the teeth of the rack 43 will only cause the block 49 to rotate while the rack 43 moves upward, and will not drive the turntable 47 to rotate, thereby ensuring the stability of the support seat 7. This cycle is repeated, so that the support seat 7 always drives the stainless steel tube to move in one direction, thereby realizing continuous stamping of the stainless steel tube, wherein the third elastic component 410 can be a spring.

[0038] See also Figure 4 The punching platform 2 is provided with symmetrically distributed clearance grooves 44 for the rack 43 to pass through;

[0039] The setting of the clearance groove 44 can avoid the interference of the stamping platform 2 with the downward movement of the rack 43, so that after the rack 43 drives the turntable 47 to rotate, the lifting plate 6 can support the stainless steel through the supporting mechanism 3 and punch the stainless steel pipe through the punch 10.

[0040] See also Figure 4 A slider 11 is fixed at the bottom of the support seat 7, and a slideway 12 adapted to the slider 11 is provided at the top of the stamping platform 2. The lower end of the slider 11 is located inside the slideway 12 and is slidably connected to the slideway 12;

[0041] The slideway 12 can limit the support seat 7 through the slider 11, thereby effectively improving the stability of the support seat 7 during movement.

[0042] Working principle: When the punching machine continuously punches the stainless steel pipe, the stainless steel pipe is placed on the surface of the support seat 7, and then the hydraulic cylinder 5 is used to drive the lifting plate 6 to move downward. The lifting plate 6 moves downward while driving the rack 43, the punch 10 and the extrusion plate 311 to move downward. First, the rack 43 squeezes the block 49 through the teeth, and then the block 49 drives the turntable 47 to rotate. The turntable 47 drives the gear 41 to rotate through the rotating rod 45, so that the support seat 7 drives the stainless steel pipe to move forward a certain distance. When all the teeth move to the bottom of the block 49, even if the lifting plate 6 continues to move downward , the turntable 47 is also unable to rotate, thereby ensuring the stability of the support seat 7. Subsequently, the extrusion plate 311 squeezes the inclined surface of the trapezoidal block 35, so that the trapezoidal block 35 drives the slide bar 37 to move horizontally, thereby making the two arc-shaped support plates 31 move away from each other. When the side wall of the extrusion plate 311 fits with the plane of the trapezoidal block 35, the arc-shaped support plate 31 fits tightly with the inner wall of the stainless steel pipe, so that the arc-shaped support plate 31 can support the stainless steel pipe from the inside of the stainless steel pipe, effectively improving the stability of the stainless steel pipe during the stamping process, and also avoiding the deformation of the stainless steel pipe during the stamping process.
