Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1 and 2, a separator cutting device with a reinforcing rib and a flanging structure is used for cutting a separator into a specified length; in the embodiment, the cut partition plate is obtained by processing a coiled metal plate in a continuous cold roll forming mode; the formed shelf partition comprises an integrally formed partition main body 100, three reinforcing ribs 200 positioned below the partition main body 100, and flanges 300 positioned at two sides of the partition main body 100. The reinforcing rib 200 is specifically a triangular groove body and a closed connecting section which are processed by cold roll forming of partial areas of the plate. Because the shelf partition plate is obtained by continuously forming coiled plates, the shelf partition plate needs to be cut according to a specified length; the reinforcing ribs and the flanging structure improve the cutting difficulty of the plate, so that the existing blade type cutting equipment is easy to cause the serious deformation of the partition plate in the cutting process.

As shown in fig. 2, the partition plate cutting device comprises a frame 1, a hydraulic cylinder 2, a partition plate positioning block 3, a cutter mounting plate 4, a cutting knife 5 and a guide positioning assembly 6. The hydraulic cylinder 2 is fixed on the top of the frame 1, and the piston rod is arranged downwards. The cutter mounting plate 4 is fixedly or rotatably connected with the end part of the piston rod through a connecting piece. The guide positioning assembly 6 comprises a guide rail 6-1, a sliding block, an intermediate rod 6-2, a first connecting rod 6-3 and a second connecting rod 6-4. Two guide rails 6-1 which are vertically arranged are respectively fixed on two sides of the frame 1. The two sliding blocks are respectively connected on the two guide rails 6-1 in a sliding manner. The two ends of the cutter mounting plate 4 are respectively fixed with the two sliding blocks. One ends of the two first connecting rods 6-3 are respectively and rotatably connected with different positions of a cross beam at the top of the frame 1; the other ends of the two first connecting rods 6-3 are respectively and rotatably connected with the two ends of the middle rod 6-2 which is horizontally arranged to form a first parallelogram mechanism. One end of each of the two second connecting rods 6-4 is rotatably connected with the two ends of the middle rod 6-2 respectively; the other ends of the two second connecting rods 6-4 are respectively and rotatably connected with different positions of the cutter mounting plate 4 to form a second parallelogram mechanism. A vertically arranged cutting knife 5 is fixed at the bottom of the knife mounting plate 4.

The guide rail 6-1 in the guiding and positioning assembly 6 is used for providing vertical guide for the cutter mounting plate 4, and each connecting rod is used for utilizing the characteristics of a parallelogram mechanism to ensure that the cutter mounting plate 4 is kept parallel to a cross beam at the top of the rack, so that the cutter mounting plate 4 is prevented from turning over in the cutting process, the condition that the cutter mounting plate 4 is clamped on the guide rail 6-1 is avoided, and the stress of different positions of the partition plate is ensured to be uniform.

As shown in fig. 3, the partition positioning block 3 is fixed to the frame 1 and located right below the cutter mounting plate 4. The partition positioning block 3 is provided with a guiding positioning groove. The guide positioning groove comprises a horizontal groove section 3-1, three reinforcing rib accommodating grooves 3-2 positioned below the middle part of the horizontal groove section 3-1 and two flanging accommodating grooves 3-3 positioned below two ends of the horizontal groove section 3-1. In the working process, the cut partition plate passes through the guide positioning groove; the guide positioning groove is used for supporting and limiting different positions of the partition plate when the partition plate is cut, and overall deformation of the partition plate in the cutting process is reduced. The top of the clapboard positioning block 3 is provided with a cutting abdicating seam; the cutting abdication slot divides the guide positioning slot into two parts from top to bottom. The cutting abdication seam is aligned with the cutting off knife 5 and is used for providing space for the cutting off knife 5 to cut off the partition board in the guide positioning groove.

As shown in fig. 4, the bottom edge of the cutting blade 5 is provided with a cutting edge. The shape of the cutting edge comprises five sawtooth cutting sections 5-1 and four concave sections 5-2 which are alternately arranged in sequence. The five sawtooth cutting sections 5-1 are respectively aligned with the three reinforcing rib accommodating grooves 3-2 and the two flanging accommodating grooves 3-3 in the guide positioning groove. The inward concave section 5-2 is composed of two symmetrical straight line sections. The vertical distance from the most concave point of the concave section 5-2 to the sawtooth cutting section 5-1 is equal to the thickness of the cut separator (i.e. the distance between the top surface of the separator main body and the bottom surface of the reinforcing rib).

In the cutting process, the five sawtooth cutting sections 5-1 firstly contact the three reinforcing ribs 200 and the two flanging positions of the cut partition plate, and cut the three reinforcing ribs 200 and the two flanging with larger thickness; the sawtooth structure on the sawtooth cutting section 5-1 improves the cutting effect on the reinforcing ribs 200 and the flanges 300 with the space structures; thereafter, as the cutoff knife 5 is lowered, the horizontal portion of the partition is gradually cut by the inclined concave section until the cut partition is completely cut. The step-by-step cutting mode realizes the key cutting of the reinforcing ribs and the flanges which are difficult to cut, avoids the situation that all areas of the partition plate simultaneously contact the cutting-off knife and disperse the cutting pressure, and reduces the deformation of the cut partition plate.

Due to the characteristics of cutting processing, the cut-in side of the cut metal piece is very flat, and burrs often appear on the cut-out side; in the embodiment, since the cutting blade 5 cuts the rib 200 of the partition plate from the top plane to the bottom plane, the upper edge of the cut section (i.e. the edge close to the top plane) is very flat; all burrs are formed at the lower edge of the cross section. The two ends of the goods shelf partition plate need to be provided with the edge protection strips, and the edge protection strips can be propped against the lower surface of the goods shelf partition plate, so that the sharp ends of burrs are propped against the edge protection strips, and people cannot be injured; therefore, in the embodiment, the two ends of the shelf partition plate obtained by cutting the partition plate from the top surface to the bottom surface do not need to be subjected to deburring treatment such as grinding, so that the process is further simplified, and the cost of the shelf partition plate is reduced.

Two ends of the bottom of the cutting-off knife 5 are provided with limit blocks 5-3. The bottom surface of the limiting block 5-3 is lower than the lowest position of the cutting edge of the cutting-off knife 5. The baffle positioning block 3 is provided with a blocking part corresponding to the two limiting blocks 5-3 respectively. The two blocking parts are respectively positioned at two ends of the guide positioning groove. When the cutting-off knife 5 moves to the lower limit position, the limiting block 5-3 on the cutting-off knife 5 abuts against the corresponding blocking part; a gap is reserved between the cutting edge of the cutting-off knife 5 and the bottom of the cutting abdication seam. The limiting blocks 5-3 can prevent the cutting edge of the cutting-off knife 5 from directly impacting the partition plate positioning block 3, so that the service life of the cutting-off knife 5 is prolonged.

The working principle of the utility model is as follows:

penetrating the cut partition board through a guide positioning groove on a partition board positioning block 3, and enabling the distance between the end surface of the partition board and the cutting abdicating seam to be consistent with the target length; pushing out by the hydraulic cylinder to enable the cutting-off knife to extend into the cutting abdicating seam to cut off the partition plate; when the cutting-off knife moves to the lower limit position, the limiting block is contacted with the upper blocking part of the partition positioning block, so that the cutting edge of the cutting-off knife is prevented from being damaged; and finally, the hydraulic cylinder drives the cutting-off tool to reset upwards.
