Description

Technical Field

[0001] This utility model relates to the technical field of cutting elliptical parts off a strip of material, and in particular to a strip cutting device with a receiving function. Background Technology

[0002] The structure with material attached produced in a certain workshop is as follows Figures 1-2 As shown, it includes a strip-shaped outer frame 1, on which multiple carriers 2 are formed at intervals along their length. Each carrier 2 has an elliptical part 3 fixedly connected to its right end. The thickness of the elliptical part 3 is 0.6~1mm. The process requires cutting the connection between the elliptical part 3 and the carrier 2 using a cutting die. After cutting, the elliptical part 3 falls onto the workbench surface, as... Figure 3 The diagram shows the structure of the cut-out oval part 3. The oval part 3 that fell onto the worktable is then sucked away by the suction head of the gripping mechanism.

[0003] The method for cutting off the various elliptical parts 3 from the strip material using the cutting die and the pulling mechanism is as follows: First, the pulling mechanism pulls the first end of the strip material directly below the cutting die. At this time, the connection between the carrier 2 and the elliptical part 3 is located directly below the cutter of the cutting die. Then, the cutting die cuts off the connection between the elliptical part 3 and the carrier 2. The cut elliptical part 3 falls onto the workbench and is finally sucked away by the suction head of the gripping mechanism.

[0004] However, while the existing cutting die and feeding mechanism can cut the elliptical part 3 from the strip, it still exhibits the following technical shortcomings:

[0005] The oval parts 3 cut from the strip fall haphazardly onto the worktable, some even stacked together. This results in the gripping mechanism's suction head picking up 2-3 oval parts 3 at a time, while the process requires the suction head to pick up only one oval part at a time. To solve this problem, workers have to separate the stacked oval parts 3, which undoubtedly increases the gripping process and makes it take a long time to cut all the oval parts off the strip, thus reducing the strip cutting efficiency.

[0006] Therefore, there is an urgent need for a material cutting device with receiving function that eliminates the need for workers to sort out stacked oval parts and greatly improves the efficiency of material cutting. Utility Model Content

[0009] A cutting cylinder is fixedly mounted on the top wall of the bracket. The piston rod of the cutting cylinder passes downward through the top wall of the bracket, and a longitudinally arranged knife holder is fixedly mounted on the extended end.

[0034] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description:

[0035] like Figures 3-8 As shown, a strip cutting device with a receiving function includes a base plate 4, on which a bracket 5 and a receiving mechanism for receiving elliptical parts 3 cut from the strip are provided. The receiving mechanism includes a lifting cylinder 6 fixed on the base plate 4 and a strip seat 7 fixed on the piston rod end of the lifting cylinder 6 and arranged longitudinally. Multiple positioning components are provided on the top surface of the strip seat 7 along its length direction. The positioning components include two pads A8 and two pads B9. The two pads B9 are respectively arranged opposite to the two pads A8 on the left and right sides. A stop 10 is opened on the inner end face of each of the four pads. The cavity formed by the four stop 10 matches the outer contour of the elliptical part.

[0036] A cutting cylinder 11 is fixedly mounted on the top wall of the bracket 5. The piston rod of the cutting cylinder 11 passes through the top wall of the bracket 5 downwards, and a longitudinally arranged knife holder 12 is fixedly mounted on the extended end. Multiple cutting blades 13 are fixedly mounted on the bottom surface of the knife holder 12. A horizontal cylinder 14 is fixedly mounted on the side wall of the bracket 5. The piston rod of the horizontal cylinder 14 passes through the bracket 5 to the right, and a movable plate 15 is fixedly mounted on the extended end. Multiple support blocks 16 corresponding to the positioning components are fixedly mounted on the right end face of the movable plate 15 along its length direction.

[0037] Three positioning components are provided on the strip-shaped base 7, with two pads A8 of the positioning components symmetrically arranged on the left and right sides with two pads B9 respectively. Three support blocks 16 are fixed on the right end face of the movable plate 15, with the top surface of the support blocks 16 flush with the top surface of the movable plate 15. The lifting cylinder 6 is vertically arranged, and its cylinder body is fixed on the top surface of the base plate 4. The cutting cylinder 11 is vertically arranged, and its cylinder body is fixed on the top surface of the bracket 5.

[0038] The cutting device also includes a controller, which is electrically connected to the lifting cylinder 6, the cutting cylinder 11 and the horizontal cylinder 14 via a signal line. The worker can control the extension or retraction of the piston rods of the lifting cylinder 6, the cutting cylinder 11 and the horizontal cylinder 14 through the controller, thereby facilitating the worker's operation.

[0039] The method of cutting off the various elliptical parts 3 from the strip material using the material pulling mechanism of this utility model is as follows:

[0040] S1, The material is fed by the feeding mechanism as follows Figures 1-2 The first end of the strip shown is pulled directly above the strip seat 7. At this time, the three oval parts 3 located on the first end of the strip are directly above the three positioning components.

[0041] S2. The piston rod of the lifting cylinder 6 controlling the receiving mechanism extends upward, driving the strip seat 7 to move upward. The strip seat 7 drives the three positioning components to move upward synchronously. When the piston rod of the lifting cylinder 6 is fully extended, the elliptical part 3 on the material is just accommodated in the cavity formed by the four stops 10 of the positioning components. Figures 9-10 As shown, the connection between the elliptical part 3 and the carrier 2 is exactly below the cutter 13, and the cavity of the positioning component is exactly opposite to the support block 16 on the left and right.

[0042] S3. The piston rod of the horizontal cylinder 14 extends to the right, causing the movable plate 15 to move to the right. The movable plate 15 then causes the three support blocks 16 to move to the right synchronously. The three support blocks 16 move towards the cavities of the three positioning components respectively. When the piston rod of the horizontal cylinder 14 is fully extended, the support blocks 16 are just supported on the bottom surface of the carrier 2. Figures 11-12 As shown;

[0043] S4. The piston rod of the control cutting cylinder 11 extends downward, driving the cutter 13 to move downward. The cutter 13 cuts off the connection between the elliptical part 3 and the carrier 2. Figure 13 As shown, at this time, each of the three positioning components contains an elliptical part 3;

[0044] S5. Control the piston rod of the cutting cylinder 11 to retract upwards, the piston rod drives the cutter 13 to move upwards, and then control the piston rod of the horizontal cylinder 14 to retract to the left, the piston rod drives the movable plate 15 to move to the left, and the movable plate 15 drives the three support blocks 16 to reset.

[0045] S6. The piston rod of the lifting cylinder 6 retracts downward, causing the strip seat 7 to move downward. The strip seat 7 then causes the three positioning components to move downward, and the positioning components cause the elliptical part 3 to move downward. Figure 14 As shown, after the piston rod of the lifting cylinder 6 is fully retracted, the suction head of the gripping mechanism sequentially picks up the elliptical parts 3 from the three positioning components, in the following direction: Figure 14 As indicated by the middle arrow;

[0046] S7. Repeat steps S1 to S6 multiple times to cut out all the oval parts 3 from the strip.

[0047] In step S2, when the piston rod of the lifting cylinder 6 is fully extended, the elliptical part 3 on the strip is perfectly accommodated within the cavity formed by the four stops 10 of the positioning assembly. In step S4, when the piston rod of the cutting cylinder 11 extends downward, the cut elliptical part 3 remains in the cavity. Since the three positioning assemblies are spaced apart, the cut elliptical parts 3 are also spaced apart and do not stack, thus ensuring that the suction head can only pick up one elliptical part at a time. Therefore, compared to the original cutting mold, this cutting device effectively avoids the stacking of cut elliptical parts, eliminating the need for workers to separate the stacked elliptical parts 3, thereby reducing the gripping process and enabling the cutting of all elliptical parts on the strip in a short time, thus greatly improving the cutting efficiency of the strip.

Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
