Detailed Description
The present invention will now be further described with reference to the accompanying drawings and detailed description.
As shown in fig. 1-5, a picnic table leg tube V-port die-cutting device may include an upper die 1, a lower die 2 and a punch 3. The upper die 1 and the lower die 2 are both of cuboid structures. The upper and lower molds 1 and 2 have the same length and width, and the same or different heights. The lower part of the upper die 1 is provided with an upper rectangular groove 11 with an opening facing downwards and extending along the length direction, and a V-shaped (isosceles triangle-shaped) groove 12 transverse to the upper rectangular groove 11. The upper part of the lower die 2 is provided with a lower rectangular groove 21 with an upward opening extending along the length direction and an isosceles trapezoid groove 22 transverse to the lower rectangular groove 21. The upper rectangular groove 11 and the lower rectangular groove 21 form a longitudinal channel a through which a foot tube (not shown) passes. The longitudinal channel a is the same shape as the foot tube and is slightly larger than the table foot tube. The depths of the upper rectangular groove 11 and the lower rectangular groove 21 may be the same or different. The V-shaped groove 12 and the isosceles trapezoidal groove 22 form a transverse passage through which the punch 3 passes. The transverse channel has a shape and size substantially corresponding to the size of the V-port to be machined. The punch 3 may comprise a lower punch portion 31 and an upper punch portion 32. The upper punch portion 31 has an isosceles triangle-shaped cross section, and the lower punch portion 32 has an isosceles trapezoid-shaped cross section. The blanking end face of the upper punch portion 31 is retracted a distance into the blanking end face of the lower punch portion 32 and the lower punch portion 32 is in driving connection with the blanking cylinder. When punching, the lower punch part 32 firstly punches an isosceles trapezoid notch on the leg tube, and then the upper punch part 31 punches an isosceles triangle notch on the leg tube, and the isosceles trapezoid notch and the isosceles triangle notch form the required V-shaped opening. That is, the V-shaped opening is formed by punching in two portions with a staggered arrangement. Therefore, the required punching force is small; and the punch 3 is not easy to damage and long in service life, so that the processing cost is greatly reduced, meanwhile, the product is not easy to deform, and the reject ratio of the product is reduced.
In order to facilitate the assembly of the upper die 1 and the lower die 2, the upper die 1 and the lower die 2 are positioned in a matched mode through a concave-convex structure. In the illustrated embodiment, the lower end surfaces of the upper mold 1 on both sides of the upper rectangular groove 11 are respectively provided with a groove 13 extending in the length direction, and the upper end surfaces of the lower mold 2 on both sides of the lower rectangular groove 21 are respectively provided with a protrusion 23 extending in the length direction. When the die is installed, the upper die 1 and the lower die 2 are engaged in the convex strips 23 through the grooves 13 to realize positioning fit. Preferably, the corners of the grooves 13 and the ribs 23 are rounded.
The upper die 1 and the lower die 2 are fixedly mounted on corresponding brackets (not shown) by being screwed in the screw holes 14 and 24 by screws (not shown). The support can be driven by a corresponding air cylinder to lift. Corresponding guide posts (not shown) are inserted between the upper die 1 and the lower die 2. Therefore, the upper die 1 and the lower die 2 can be automatically opened and closed by controlling the corresponding cylinders.
In the embodiment shown, the longitudinal channel and the transverse channel are both centrally located. That is, the upper rectangular groove 11 and the lower rectangular groove 21 are located in the middle of the width of the upper die 1 and the lower die 2, respectively, and the V-shaped groove 12 and the isosceles trapezoid groove 22 are located in the middle of the length of the upper die 1 and the lower die 2, respectively.
As shown in fig. 4 and 5, the length L2 of the lower punch portion 32 is 5 times or more the length L1 of the upper punch portion 31 in the punching direction X, i.e., L1 is much larger than L2. Preferably, L2 ═ 10L 1. The upper punch portion 31 may be located in the middle of the lower punch portion 32 or offset towards the blanking end face of the lower punch portion 32. In the present embodiment, the distance L3 between the die-cut end surface of the upper punch portion 31 and the die-cut end surface of the lower punch portion 32 is greater than the thickness of the leg tube, which ensures that the lower punch portion 32 and the upper punch portion 31 are not die-cut simultaneously, reducing the required die-cutting force.
In the present embodiment, the length of the upper punch portion 31 is tapered from bottom to top. In one embodiment, the length of the lower end of the upper punch portion 31 is about 8mm greater than the length of the upper end. The height h1 of the upper punch portion 31 is greater than the height h2 of the lower punch portion 32. For example, h1 is 1-2 h 2.
In addition, in the present embodiment, the fixed end of the lower punch part 32 is provided with a fixed hole 33, and the upper and lower surfaces of the fixed end are lower than the other parts of the lower punch part 32, that is, the upper and lower surfaces of the fixed end and the other parts of the lower punch part 32 form an upper step and a lower step, so as to facilitate the fixed installation of the lower punch part 32.
Preferably, the upper die, the lower die and the punch may be all made of Cr12MoV steel to prolong the service life thereof.
While the invention has been particularly shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
