Description

Technical Field

[0001] The utility model relates to the technical field of production of water valve sealing gaskets, in particular to a tooling for punching cutters with movable blades and self-positioning, which is suitable for water valve sealing gaskets. Background Art

[0002] Water valve gaskets are used in multi-port valves in the thermal management systems of new energy vehicles. These gaskets control the opening and closing seals of the water valves. Failure of these gaskets can directly lead to valve failure, causing fluid leakage and unstable operation, impacting the stable operation of the thermal management system. While these gaskets offer promising development prospects and significant future production capacity, they require precise deburring of each valve during production, resulting in low production efficiency.

[0003] When producing water valve gaskets, for example, in the patent document with application number 202223516448.8, a gasket processing device is disclosed, and it is specifically disclosed that by installing a punching head and a grinding sleeve and other mechanisms on the punching rod, the grinding work can be performed immediately after the punching work is completed, thereby achieving precise processing of the gasket.

[0004] The water valve gasket is made of rubber and soft skeleton, which is very easy to deform. The traditional punching knife cannot automatically align the tool, and it is difficult to ensure the punching effect of the inner hole. The product qualification rate is low. In addition, when the water valve gasket is stamped, it is easy to produce flash on the side of the product, affecting the quality of the product. Utility Model Content

[0005] The utility model aims to provide a self-positioning punching tool with a movable blade suitable for a water valve sealing gasket.

[0006] The technical problem solved by the utility model is to solve the problem in the prior art that the traditional punching cutter cannot automatically align the cutter, resulting in a low inner hole punching effect.

[0007] The utility model can be realized through the following technical scheme: a blade movable self-positioning punching tool suitable for water valve sealing gasket, including a pad and a pressure plate, an upper plate is fixedly installed on the pad, a plurality of inner hole punching knives are installed in the upper plate in a limited position, and a reserved gap is set between the upper plate and the inner hole punching knife.

[0008] A further technical improvement of the utility model is that a guide groove is provided on the pressing plate, and a guide column for sliding connection with the guide groove is fixed on the backing plate.

[0009] A further technical improvement of the utility model is that an outer edge punching knife for cutting the flash of the side edge of the sealing gasket is fixed on the upper plate.

[0010] A further technical improvement of the present invention is that a limiting sliding groove is provided on the pressing plate, and an adsorption plate for adsorbing and limiting the sealing gasket is slidably provided inside the limiting sliding groove.

[0011] A further technical improvement of the present utility model is that a first sliding groove is opened inside the limiting sliding groove, and the size of the first sliding groove is smaller than that of the limiting sliding groove, an internal cylinder is fixed inside the first sliding groove, an adsorption plate is provided at the output end of the internal cylinder, and the adsorption plate and the first sliding groove are slidably connected.

[0012] The further technical improvement of the present invention is that a rolling cylinder is fixed inside the limiting slide groove, a rolling base is provided at the output end of the rolling cylinder, the rolling base is frame-shaped, and the rolling base is located outside the adsorption plate, and a rotating pressure roller is movably provided on the rolling base.

[0013] A further technical improvement of the present invention is that the rotating pressure roller is rotatably mounted on the mounting base, the mounting base is mounted on the moving conveyor belt, and the moving conveyor belt is driven by the driving roller driven by the power equipment.

[0014] A further technical improvement of the utility model is that a buffer groove is provided on the adsorption plate, a sliding pressure plate is provided on the buffer groove through spring sliding, and the sliding pressure plate is used to cooperate with the inner hole punch.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present application sets a pad and a pressure plate, installs an upper plate on the pad, and installs an inner hole punch on the upper plate, so that several inner hole punches can be used to work separately. That is, when in use, the inner hole punch contacts the limiting groove of the pad, and the position of the inner hole punch is adaptively adjusted through the limiting groove, so that the inner hole punch slides adaptively in the reserved gap, so that several sealing gaskets can be positioned and cut separately, ensuring that the tool can be automatically aligned, thereby ensuring the inner hole punching effect and ensuring a high product qualification rate.

[0017] 2. The present application uses an outer edge punch so that when the inner hole punch is in use, the outer edge punch also acts on the sealing gasket, and the outer edge punch is used to cut the edge position of the sealing gasket, and the burrs of the sealing gasket are fully cut, thereby improving the quality of the product, and through the automated burr cutting operation, saving manpower and ensuring the production efficiency of the product.

[0018] 3. The present application arranges an adsorption plate on the pressure plate so that when the sealing gasket is placed on the adsorption plate, the vacuum adsorption holes on the adsorption plate can be used to maintain the position of the sealing gasket, thereby avoiding the problem of folding, bending or other deformation of the sealing gasket due to its own material under the action of gravity, thereby ensuring the cutting accuracy.

[0019] 4. The present application sets a rotating pressure roller and uses the rotating pressure roller to act on the sealing gasket, so that the sealing gasket can be flattened and then fixed on the adsorption plate through the vacuum adsorption hole, thereby further ensuring the stability of the sealing gasket and ensuring that the sealing gasket is fixed relatively flatly on the adsorption plate, thereby further ensuring the cutting accuracy.

[0020] 5. When the upper plate is squeezed on the sealing gasket to fix it, the upper plate continues to move upward, and the sealing gasket is very easy to deform. Therefore, in this application, there is no need to align the sealing gasket with the upper plate for squeezing. At this time, after the inner hole punch cuts the rubber pad, the cut and removed material is pressed tightly on the sliding pressure plate and is stored in the buffer groove by the action of the spring. Later, when cutting the material, the spring can push the removed material out to avoid deformation of the sealing gasket. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] In order to further illustrate the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the following is a detailed description of the specific implementation method, structure, characteristics and effects of the present invention in combination with the accompanying drawings and preferred embodiments.

[0030] See also Figure 1-6 As shown, a blade movable self-positioning punching tool suitable for water valve sealing gaskets includes a pad 5 for bottom support and a pressure plate 1 for cooperating with the pad 5. A cutter mechanism is provided on the pad 5. When in use, the sealing gasket 7 is placed on the cutter mechanism, and the pressure plate 1 is placed on the pad 5. Pressure is applied to the pressure plate 1 so that the pressure plate 1 presses the sealing gasket 7 downward, causing the cutter mechanism to work and punch and form the sealing gasket 7.

[0031] In order to achieve the positioning of the pressure plate 1 and the pad 5, a guide groove is opened on the side of the pressure plate 1, and a guide column 2 is fixed on the pad 5. The guide column 2 and the guide groove are slidably connected. In this application, multiple groups of guide grooves and guide columns 2 are provided, and the positioning of the guide columns 2 and the pad 5 is achieved through multi-point positioning to ensure the relative stability of the positions of the guide columns 2 and the pad 5.

[0032] In the present application, the cutting mechanism includes an internal cutting component and a flash cutting component. First, the internal cutting component includes an inner hole punch 6, which is installed on the upper plate 4, and a reserved gap 8 is left between the inner hole punch 6 and the upper plate 4, so that the inner hole punch 6 can still move in a small range after assembly to achieve fine-tuning of the horizontal position. When the end of the inner hole punch 6 contacts the limiting ring on the sealing gasket 7, the range of the inner hole punch 6 will be adaptively adjusted so that the inner hole punch 6 can enter the inside of the limiting ring. Even if there is a deviation between the position of the sealing gasket 7 and the position of the inner hole punch 6, it can be accurately punched.

[0033] The flash cutting mechanism includes an outer edge punch 3, wherein the outer edge punch 3 is fixedly mounted on the upper plate 4. The outer edge punch 3 is used to directly cut the edge of the sealing gasket 7, and the flash of the sealing gasket 7 can be directly cut off, thereby ensuring the efficiency of the edge processing of the sealing gasket 7. When working, it is only necessary to place the sealing gasket 7 with the flash on the tooling, and use the sealing gasket 7 to punch the outer edge punch 3 to the correct position. The inner hole punch 6 has a self-positioning function, and can automatically position itself to the correct inner hole position on the sealing gasket 7 within a certain range, and is sent into the press for pressurization. Under the extrusion of the pressing plate 1 and the punch, the inner hole and the external flash of the sealing gasket 7 are cut off at the same time, and the punching of products with different hole spacings can be achieved through cooperation.

[0034] In the present application, when the sealing gasket 7 is placed on the pad 5, due to the different support heights of the inner hole punch 6, the outer edge punch 3 and the upper plate 4, the sealing gasket 7 will produce a change in curvature under the action of gravity, which will cause the sealing gasket 7 and the pad 5 to be not level, resulting in the cutting accuracy of the sealing gasket 7 being affected. Therefore, the present application provides a limiting slide groove on the pressure plate 1, and a limiting component is slidingly set inside the limiting slide groove. The sealing gasket 7 is flatly placed using the limiting component, so that the sealing gasket 7 can be kept level with the pad 5. Then, when the pressure plate 1 is placed above the pad 5, the sealing gasket 7 can be cut directly to ensure the cutting stability of the sealing gasket 7.

[0035] Therefore, the limiting component includes an adsorption plate 11, and a first sliding groove 9 is also opened above the limiting slide groove. The size of the first sliding groove 9 is smaller than the limiting slide groove, and an adsorption plate 11 is slidingly arranged inside the first sliding groove 9, wherein the adsorption plate 11 is installed at the output end of the internal cylinder 10, wherein the internal cylinder 10 is installed inside the first sliding groove 9. When in use, the internal cylinder 10 is started to make the adsorption plate 11 move inside the first sliding groove 9, and the end of the adsorption plate 11 away from the internal cylinder 10 is used to realize the adsorption and placement of the sealing gasket 7. When in use, the pressure plate 1 is first turned over and placed, and then the sealing gasket 7 is placed on the adsorption plate 11, and the vacuum adsorption port 23 on the adsorption plate 11 is used to adsorb and fix the sealing gasket 7, so that the placement and fixation of the sealing gasket 7 can be realized, ensuring that the sealing gasket 7 is not affected by gravity.

[0036] The pressing roller 14 is driven by the cylinder 12 to press the sealing gasket 7 on the adsorption plate 11.

[0037] The moving component includes a driving roller 15, wherein the driving roller 15 is rotatably mounted on the rolling base 13, and the driving roller 15 is controlled to rotate by a driving motor and a transmission chassis. A moving conveyor belt 16 is arranged between adjacent driving rollers 15, and a mounting block 18 is fixedly mounted at a fixed position of the moving conveyor belt 16. The mounting block 18 is slidingly connected to the rolling base 13, and a mounting base 17 is fixed on the mounting block 18. A rotating pressure roller 14 is rotatably arranged on the mounting base 17. At startup, the driving motor and the transmission chassis cooperate to drive the driving roller 15 to rotate, drive the moving conveyor belt 16, and then drive the mounting block 18 to be slidingly connected to the rolling base 13, thereby controlling the rotating pressure roller 14 to flatten the sealing gasket 7 on the adsorption plate 11.

[0038] Since the sealing gasket 7 has a certain thickness, when the inner hole punch 6 punches and cuts the sealing gasket 7, the sealing gasket 7 is tightly attached to the lower surface of the adsorption plate 11. When the inner hole punch 6 contacts the sealing gasket 7 and cuts the sealing gasket 7, the sealing gasket 7 is squeezed, causing the cutting part of the sealing gasket 7 to deform, resulting in uneven size of the cut edge.

[0039] Based on the above technical problems, the adsorption plate 11 includes an adsorption substrate 19, a buffer groove is opened on the adsorption substrate 19, a buffer pressure plate 20 is fixed at the bottom of the buffer groove, a spring pressure groove 21 for evenly installing the spring is opened on the side of the buffer pressure plate 20, and a sliding pressure plate 22 is fixed at the other end of the spring, wherein the sliding pressure plate 22 is slidably connected to the buffer groove, and the end of the sliding pressure plate 22 is limited by the adsorption substrate 19. During use, when the edge position of the inner hole punch 6 cuts the sealing gasket 7, the cut position of the sealing gasket 7 is squeezed on the sliding pressure plate 22. At this time, the spring is squeezed and the sliding pressure plate 22 slides inside the buffer groove. At this time, the cut part of the sealing gasket 7 remains on the sliding pressure plate 22 until the cutting is completed. When the pressure plate 1 is away from the pad 5, the cut sealing gasket 7 is ejected and dropped under the action of the spring, which can reduce the deformation caused by the cutting edge position of the sealing gasket 7.

[0040] When the present invention is in use, the pressing plate 1 is first turned over and placed, and then the sealing gasket 7 is placed on the adsorption plate 11. At this time, the vacuum adsorption port 23 does not produce any action, so that the sealing gasket 7 can be initially placed and fixed. Subsequently, the rolling cylinder 12 is started to control the height of the rolling base 13, and then the rotating pressure roller 14 is driven to move above the sealing gasket 7 by starting the moving component. The rolling cylinder 12 is used to drive the rotating pressure roller 14 to press tightly on the sealing gasket 7. Subsequently, the moving component is started to drive the rotating pressure roller 14 to move, and the sealing gasket 7 on the adsorption plate 11 is rotated and flattened. At this time, the vacuum adsorption port 23 adsorbs and fixes the sealing gasket 7 to ensure that the sealing gasket 7 is not affected by gravity, and then the pressure plate 1 is placed on the pad 5, and the guide column 2 is used to enter the guide groove to limit the position of the pad 5 and the pressure plate 1, and then it is placed inside the press for pressurization; during the pressurization process, the end of the inner hole punch 6 contacts the limiting ring on the sealing gasket 7, and the range of the inner hole punch 6 will be adaptively adjusted so that the inner hole punch 6 can enter the inside of the limiting ring. Even if there is a deviation between the position of the sealing gasket 7 and the position of the inner hole punch 6, it can be accurately punched; at the same time, the sealing gasket 7 is used to make the outer edge punch 3 punch to the correct position, and the external burr of the sealing gasket 7 is cut off at the same time, and the punching of products with different hole spacings can be achieved through cooperation.

Although the present invention has been disclosed as a preferred embodiment, it is not intended to limit the present invention. Any person skilled in the art can make some changes or modifications to equivalent embodiments using the technical contents disclosed above without departing from the scope of the technical solution of the present invention.
