When a component is considered to be "connected to" another component, it may be directly connected to the other component or there may also be a component centered. When a component is considered to be "set on" another component, it may be directly set on the other component or there may also be a component centered. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only.

[0020] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0021] The present invention will be further described below in conjunction with the accompanying drawings and embodiments:

[0022] like Figures 1 to 3 As shown, a sealing component special-shaped end punching device includes a base 1, a guide rail 2, a guide base 3, a stopper 4, a first bolt 5, a cutter fixing slide 6, a power source 7, a cutter 8, a second bolt 9, a cutter pressing block 10, a third bolt 11, an inclined wedge 12, a supporting and positioning die assembly 13, a clamping die 14 and a handle 15.

[0023] Two parallel guide rails 2 are provided on the base 1 , and guide bases 3 are slidably mounted on the two guide rails 2 . The guide bases 3 and the two guide rails 2 are arranged obliquely.

[0024] Since the guide base 3 moves in an inclined direction on the two guide rails 2, the two guide rails 2 cannot be arranged in an aligned manner. Specifically:

[0025] The two guide rails 2 are divided into a first guide rail 201 and a second guide rail 202 arranged in parallel. Figure 2 As shown, the first guide rail 201 and the second guide rail 202 are staggered in the length direction. The front end of the first guide rail 201 is closer to the front end of the base 1, and the rear end of the second guide rail 202 is closer to the rear end of the base 1.

[0026] A stopper 4 is fixed to the end of the first guide rail 201 on the base 1 , and the side wall of the guide base 3 is fixed to the stopper 4 by a first bolt 5 . A handle 15 is provided on the top of the guide base 3 .

[0027] When the guide base 3 moves to the position of the stopper 4, it is in the working position, and needs to be fixed to the stopper 4 by the first bolt 5 at the working position to avoid movement during the working process.

[0028] The handle 15 facilitates the movement of the guide base 3 on the two guide rails 2 .

[0029] The form of the handle 15 is not fixed, for example, an n-shaped structure may be adopted.

[0030] The front and rear side walls of the guide base 3 are penetrated by product channels, and a supporting and positioning die assembly 13 is installed at the product channel on the side of the guide base 3 facing the stopper 4. A vertically movable clamping die 14 is installed above the supporting and positioning die assembly 13 in the guide base 3, and a through hole is provided on the clamping die 14.

[0031] The supporting and positioning die assembly 13 is used to support and position the product 16 , and the supporting and positioning die assembly 13 includes a first die 1301 , a second die 1302 , and a third die 1303 fixed on the guide base 3 .

[0032] The pressing die 14 is used to press the product 16 downward to form a compaction.

[0033] A cutter fixing slider 6 is installed in the guide base 3 for sliding left and right. One end of the cutter fixing slider 6 is connected to a power source 7 and the other end is installed with a cutter 8. A cutter pressing block 10 is installed at the end of the cutter fixing slider 6 corresponding to the installation position of the cutter 8 through a second bolt 9. The cutter pressing block 10 is used to block the cutter 8. When disassembling and replacing, the cutter pressing block 10 is removed first, and then the cutter 8 is replaced.

[0034] The form of the power source 7 is not fixed, and it can be in the form of a cylinder assembly or an oil cylinder assembly, or in other alternative forms.

[0035] In this embodiment, the power source 7 includes a cylinder fixing plate 701 fixed to the end of the guide base 3, a cylinder 702 is fixed to the outer end of the cylinder fixing plate 701, and a telescopic rod 703 of the cylinder 702 is fixedly connected to the cutter fixing slider 6 through a cylinder joint 704.

[0036] The cutter fixing slider 6 is installed with an inclined wedge 12 above the cutter 8 through a third bolt 11. The bottom of the inclined wedge 12 is provided with a first plane 1201 and a second plane 1202. The first plane 1201 is higher than the second plane 1202. An inclined wedge inclined surface 1203 is provided between the first plane 1201 and the second plane 1202. The end corresponding to the first plane 1201 of the inclined wedge 12 is inserted into the through hole of the clamping die 14.

[0037] The inclined wedge 12 is used to control the vertical movement of the pressing die 14 so that it can press the product 16 .

[0038] The working principle of the present invention is as follows:

[0039] 1. Punching process:

[0040] When the equipment servo system drives the mold to feed, the product 16 is introduced into the supporting and positioning die assembly 13 of the punching device to the theoretical position through the feed port die; the equipment supplies air, and the retracting rod 703 of the cylinder 702 contracts to drive the cutter fixed slider 6 to move in the direction of the cylinder 702. During this process, the inclined wedge 12 fixed to the cutter fixed slider 6 presses down the clamping die 14 through the inclined wedge surface 1203, so that the clamping die 14 moves vertically downward in the guide base 3 to clamp the key parts of the product 16; then the cutter 8 starts to punch the end of the product 16 from the side driven by the cutter fixed slider 6; after the punching is completed, the waste material is introduced into the blanking area, and the cylinder 702 drives the cutter fixed slider 6 to reset, completing a punching process.

[0041] 2. Replace the tool:

[0042] Since there may be two punching devices installed in the system, and the distance between them at the working position is short, if the cutter 8 needs to be replaced, the two will interfere with each other, making it inconvenient to replace the cutter 8. At this time, it is necessary to remove the first bolt 5 connecting the stopper 4 and the guide base 3, pull the handle 15 to pull the guide base 3 to a position where it will not be affected, remove the knife pressing block 10 first, and then replace the cutter 8.

[0043] Compared with the existing technology, the technical advantages and beneficial effects of this product are:

[0044] 1. The present invention can punch the end cut and the upper and lower side frames at the same time, saving equipment stations, thereby saving the use cost of the equipment; the work that originally required three molds to complete is concentrated in one mold punching, saving mold costs; and the cut is punched as a whole, and there is no need to repeatedly debug the size of each cut, saving debugging costs.

[0045] 2. Before the punching process, a movable pressing die 14 is added to press the surface of the product 16 to ensure the quality of the cut.

[0046] 3. The mold structure is compact and space-saving, which would otherwise make it inconvenient to replace the tool. However, the present invention pulls the single-sided punching unit back and forth on the guide rail 2 to displace the two components, creating space for replacing the tool, which saves space and facilitates tool replacement.

[0047] The present invention is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
