[0030] 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.
[0031] The specific implementation of the present invention is described in detail below in conjunction with specific embodiments.
[0032] Punch 2 is installed as follows:
[0033] like Figure 2 , Figure 7As shown, the lifting assembly 4 includes a cam 42, which is rotatably arranged on the upper part of the C-shaped table 1, and a motor 41 is installed on the side of the C-shaped table 1. The output shaft of the motor 41 is connected to the cam 42, and a carrier plate 43 is arranged below the cam 42. Four guide columns 44 vertically slide through the carrier plate 43 and are fixedly connected to the C-shaped table 1. Springs are sleeved on the outside of the guide columns 44 to elastically connect the carrier plate 43 to the C-shaped table 1. The cam 42 presses downward against the carrier plate 43, and the punch 2 is fixed at the bottom center of the carrier plate 43.
[0034] The bearing member 5 is installed as follows:
[0035] like Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the lower part of the C-shaped table 1 has a planar bearing part, and a lifting groove 51 is provided inside the bearing part. The bearing member 5 slides vertically elastically in the lifting groove 51 through a spring. The top surface of the bearing member 5 is spherical. A material hole 52 is provided through the center of the surface of the bearing member 5. The material hole 52 is vertically aligned with the punching knife 2. Fan-shaped plates 53 are symmetrically arranged at the lower part of both sides of the bearing member 5. The fan-shaped plates 53 are rotatably installed in the lifting groove 51 through a torsion spring. The upper part of the fan-shaped plate 53 has an arc-shaped edge that contacts the bearing member 5, and the radial size of the upper arc-shaped edge of the fan-shaped plate 53 changes gradually.
[0036] The linear transmission element connects the lifting assembly 4 and the bearing element 5 as follows:
[0037] like Figure 3 , Fig.11 As shown, the linear conductive member includes a first rope body 6 and a second rope body 61. A sliding cavity 11 is opened at the vertical part of the side of the C-shaped table 1. The connecting component 7 is slidably arranged in the sliding cavity 11. The two ends of the first rope body 6 connect the bottom of the connecting component 7 and the lower part of the fan-shaped plate 53. The two ends of the second rope body 61 connect the top of the connecting component 7 and the carrier 43.
[0038] When punching holes in the mesh plate, the plate is positioned by a manipulator or other matching moving parts and placed on the bearing part of the C-shaped table 1. In the initial state of punching, the bearing part 5 is retracted into the lifting groove 51 by the elastic force. The motor 41 is turned on to drive the cam 42 to rotate. The cam 42 squeezes the carrier plate 43 to overcome the elasticity and push the punching knife 2 down. At this time, the descending carrier plate 43 pulls the second rope body 61, the connecting assembly 7, and the first rope body 6 to move as a whole. The first rope body 6 pulls the fan-shaped plate 53 to overcome the elastic force and deflect. The fan-shaped plate 53 pushes the bearing part 5 to move upward. When the punching knife 2 punches a hole on the surface of the plate, the spherical surface of the bearing part 5 protrudes from the bearing part to lift the plate upward, so that the punching part of the plate has a certain upward deformation amplitude, which is used to offset the downward stress caused by the punching knife 2, so that the mesh plate after punching will not be deformed due to stress concentration and the edge will not be warped.
[0039] like Figure 6 As shown, a guide cylinder 54 that passes through the bottom of the C-shaped table 1 is fixed inside the lifting groove 51, and an insertion cavity 55 is opened at the bottom of the supporting member 5. The guide cylinder 54 and the insertion cavity 55 are vertically slidably plugged in. The material hole 52 is vertically aligned with the guide cylinder 54. The inner diameter of the guide cylinder 54 is larger than the diameter of the material hole 52. The falling material generated by the punching knife 2 enters the guide cylinder 54 through the material hole 52 and is then discharged downward.
[0040] like Fig.12 As shown, the connection assembly 7 includes a slide bar 71, which is vertically slidably arranged in the slide cavity 11, a slide groove 72 is horizontally provided on the surface of the slide bar 71, two slide seats 73 are symmetrically slidably arranged in the slide groove 72, a bidirectional threaded rod 74 is rotatably arranged in the slide groove 72, and the bidirectional threaded rod 74 threads through the two slide seats 73, and rotating arms 75 are rotatably arranged on the surfaces of the two slide seats 73, and the tops of the two rotating arms 75 are rotatably connected, and the two first rope bodies 6 are respectively connected to the two ends of the slide bar 71, and the second rope body 61 is connected to the top of the rotating arm 75;
[0041] The upward movement height of the supporting member 5 is determined by the length of the first rope body 6, the connecting assembly 7, and the second rope body 61. The two slides 73 are driven closer or farther away by rotating the bidirectional threaded rod 74, so that the height of the top connection point of the two rotating arms 75 changes, thereby changing the overall length of the first rope body 6, the connecting assembly 7, and the second rope body 61, which is used to adjust the upward movement amplitude of the supporting member 5 according to the specific production conditions.
[0042] like Figure 8 , Fig. 9 , Fig.10 As shown, the pressing assembly 3 includes a box body 31, a knife hole 37 is set through the middle of the box body 31, the box body 31 has a cavity inside, and an inlet is set through the cavity at the top of the box body 31, and cutting oil is added to the cavity of the box body 31 through the inlet. The punching knife 2 slides through the knife hole 37, and a spring is connected between the box body 31 and the punching knife 2. The bottom of the box body 31 is horizontally slidably installed with a pressing plate 32, and a through hole 33 is opened on the surface of the pressing plate 32. The diameter of the through hole 33 is larger than the diameter of the knife hole 37, and the two sides of the box body 31 are symmetrically vertically slidable. There is a tripod 34, the bottom of the tripod 34 is bent at a right angle to a horizontal state, both sides of the box body 31 are coaxially elastically rotatably installed with a small gear 35 and a large gear 36 through a torsion spring, the pressure plate 32 is meshed and connected with the large gear 36 through a horizontal rack, the tripod 34 is meshed and connected with the small gear 35 through a vertical rack, a leakage hole 38 is opened at the bottom of the box body 31, the pressure plate 32 slides to block the leakage hole 38, the inside of the box body 31 and the inside of the leakage hole 38 are filled with a sponge 39, and the sponge 39 absorbs the cutting oil in the cavity of the box body 31;
[0043] Before punching, the bottom end of the punching knife 2 is retracted into the knife hole 37, and the pressing plate 32 is offset to one side of the box body 31, so that the through hole 33 and the knife hole 37 are misaligned. The bottom end of the punching knife 2 contacts the upper surface of the pressing plate 32, and the bottom of the tripod 34 is lower than the pressing plate 32. When punching, the tripod 34 first contacts the surface of the plate, and then the box body 31 continues to descend to cause vertical sliding between the tripod 34 and the box body 31. The tripod 34 drives the small gear 35 to rotate, and the large gear 36 synchronously drives the pressing plate 32 to slide horizontally. When the tripod 34 and the pressing plate 32 are at the same height, the pressing plate 32 moves to the through hole 33 and The knife hole 37 is aligned with the position, at this time, the pressure plate 32, the tripod 34, and the box body 31 remain integrated, the pressure plate 32 and the tripod 34 are pressed together on the opening part of the plate, and then the punching knife 2 continues to descend to pass through the through hole 33 to make a hole on the surface of the plate. At this time, the position of the pressure plate 32 aligned with the leakage hole 38 is smeared with cutting oil, and the punching knife 2 rises after punching is completed, and the small gear 35 and the large gear 36 are rotated by elastic force, the tripod 34 descends and resets, and the pressure plate 32 moves sideways and resets. The cutting oil smeared on the surface of the pressure plate 32 is rubbed on the bottom end of the punching knife 2, so that the punching knife 2 has a sharper effect for the next punching.
