DETAILED DESCRIPTION
[0027] like Figure 1-Figure 8 As shown, the utility model provides a technical solution: a steel pipe punching machine for door and window production, comprising a main body 1, a punching assembly 2 is provided on the top of the main body 1, an anti-pinching structure 4 is provided on the top surface of the main body 1, and a reset structure 5 is provided on the top of the main body 1.
[0028] The anti-pinching structure 4 includes: a placement plate 41, a slide groove 42, a slider 43, a clamping plate 44, a telescopic rod 45, a handle 46, a fixing shell 47, a return spring 48, an auxiliary spring 49, a clamping block 410, a clamping groove 411, a limiting rod 412, and a limiting groove 413. A placement plate 41 is fixedly connected to the top surface of the main body 1, and the main body 1 plays a fixing role on the placement plate 41. A slide groove 42 is opened on the top of the placement plate 41. Two groups of slide grooves 42 are provided on the top of the placement plate 41. A slider 43 is slidably connected to the inner wall of the slide groove 42. The slide groove 42 plays a fixing role on the moving trajectory of the slider 43. There are two groups of sliders 43, which are respectively located on the inner walls of different groups of slide grooves 42. A clamping plate 44 is fixedly connected to the top of the slider 43. There are two groups of clamping plates 44, which are respectively located on the tops of different groups of sliders 43, and the clamping plates 44 will move with the movement of the slider 43. A reset spring 48 is fixedly connected to the inner wall of the clamping plate 44. The inner wall of each group of clamping plates 44 A group of return springs 48 are provided on the wall, and the clamping plate 44 fixes the return spring 48. The inner wall of the clamping plate 44 is slidably connected with a fixed shell 47. The inner wall of each group of clamping plates 44 is provided with a group of fixed shells 47. The end of the return spring 48 away from the clamping plate 44 is fixedly connected to the fixed shell 47. The return spring 48 will push the fixed shell 47 to move away from the return spring 48 through its own elastic force. The inner wall of the fixed shell 47 is fixedly connected with an auxiliary spring 49. The inner wall of each group of fixed shells 47 is provided with a group of auxiliary springs 49, and the fixed shell 47 fixes the auxiliary spring 49. The end of the auxiliary spring 49 away from the fixed shell 47 is fixedly connected with a block 410. A group of blocks 410 are provided inside the fixed shell 47, and the auxiliary spring 49 will push the block 410 to move away from the auxiliary spring 49 through its own elastic force. A card slot 411 is provided on the top surface of the placement plate 41. There are multiple groups of card slots 411, and they are all set on the moving tracks of the two groups of card blocks 410, and the size of the card slot 411 is adapted to the size of the card block 410. A handle 46 runs through the outer wall of the main body 1, and the main body 1 supports the handle 46. The outer wall of the handle 46 is rotatably connected to the main body 1, and the outer wall of the handle 46 is fixedly connected to the telescopic rod 45. There are two groups of telescopic rods 45, which are respectively located on both sides of the handle 46. The telescopic rod 45 will move with the handle 46. The rotation performs circular motion with the handle 46 as the center, the end of the telescopic rod 45 away from the handle 46 is hinged to the slider 43, and the two groups of telescopic rods 45 are respectively hinged to different groups of sliders 43, so that the two groups of sliders 43 will move in opposite directions with the circular motion of the two groups of telescopic rods 45, and the outer wall of the handle 46 is slidably connected to the limit rod 412, and the limit rod 412 can slide along the outer wall of the handle 46. The outer wall of the placement plate 41 is provided with a limit groove 413, and the limit groove 413 is provided with a plurality of groups, and the plurality of groups of limit grooves 413 are distributed in a circle with the handle 46 as the center, and the inner wall of the limit groove 413 fits the limit rod 412, and the size of the limit rod 412 is adapted to that of the limit groove 413.
[0029] The reset structure 5 includes a fixing rod 51 and a torsion spring 52. The inner wall of the placement plate 41 is fixedly connected with the fixing rod 51. The placement plate 41 fixes the fixing rod 51. The outer wall of the fixing rod 51 passes through the handle 46. The outer wall of the fixing rod 51 is fixedly connected with the torsion spring 52. The fixing rod 51 fixes the torsion spring 52. One end of the torsion spring 52 away from the fixing rod 51 is fixedly connected with the handle 46. The torsion spring 52 drives the handle 46 to reset through its own torque.
[0030] Working principle: by moving the limit rod 412, the limit rod 412 is disengaged from the limit groove 413, thereby releasing the fixed limit of the handle 46. At this time, by rotating the handle 46, the telescopic rod 45 will perform a circular motion with the handle 46 as the center of the circle as the handle 46 rotates. At this time, the slider 43 will slide along the inner wall of the slide groove 42 with the circular motion of the telescopic rod 45. At this time, the clamping plate 44 will move with the movement of the slider 43, and then the steel pipe on the placement plate 41 is fixedly clamped by the two groups of clamping plates 44. When the clamping plate 44 moves in the direction of the steel pipe, the fixed shell 47 will move with the clamping plate The plate 44 moves, and the fixed shell 47 will first contact the outer wall of the steel pipe, and then the fixed shell 47 will retract into the clamping plate 44. At this time, the fixed shell 47 will drive the clamping block 410 to move, and then the clamping block 410 will be separated from the clamping plate 44. At this time, the clamping block 410 will move downward through the elastic force of the auxiliary spring 49, and then the clamping block 410 will be inserted into the clamping groove 411. At this time, the inclined surface of the clamping block 410 will fit the side of the clamping groove 411 close to the steel pipe, so that the clamping plate 44 cannot move in the direction of the steel pipe, thereby avoiding excessive clamping force of the clamping plate 44 on the steel pipe to cause damage to the outer wall of the steel pipe.
[0031] At the same time, when the processing is completed, the limit rod 412 can be moved out of the limit groove 413. At this time, the torsion spring 52 will drive the handle 46 to reset through its own torque, and then the telescopic rod 45 will rotate with the handle 46 to perform a circular motion in the opposite direction with the handle 46 as the center, thereby driving the slider 43 to move away from the steel pipe, and then driving the clamping plate 44 to move away from the steel pipe. At this time, the inclined surface of the block 410 will contact the inner wall of the clamping groove 411, thereby causing the block 410 to move upward and retract into the fixed shell 47, so that the clamping plate 44 can move smoothly in the direction away from the steel pipe, so that the clamping plate 44 no longer fixes the steel pipe, thereby facilitating the removal of the steel pipe.
[0032] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
