Description

Technical Field

[0001] This utility model relates to a punching tool for rubber products, belonging to the field of rubber product manufacturing technology. Background Technology

[0002] Rubber products have extremely wide applications in industrial production. During the processing of rubber products, to meet specific usage requirements, it is often necessary to form holes of various shapes and sizes on the product, among which side through-holes are a common structure. However, for some rubber products, due to their complex structure or size limitations, side through-holes are difficult to form directly through molding technology, thus requiring subsequent punching processing.

[0003] Punching is an important step in the processing of rubber products, and it has a crucial impact on the final quality and performance of the products.

[0004] Traditional rubber product punching fixtures are complex to operate, requiring a high level of technical skill and extensive experience to ensure accurate punching position and standardized hole shape. Furthermore, due to inaccurate positioning and other issues, traditional fixtures are prone to defects such as punching position misalignment and hole deformation, further impacting the yield and quality stability of rubber products.

[0007] The upper surface of the base is provided with a square hole, and the lower end of the bracket is provided with a square protrusion. The square protrusion is inserted into the square hole and then tightened by a screw screwed into the threaded through hole on the side wall of the square hole.

[0008] The upper end of the bracket is provided with a horizontal boss, the middle part of the horizontal boss is provided with a U-shaped groove, and three screws are provided in the U-shaped groove.

[0009] Both sides of the horizontal boss are provided with installation clearance.

[0010] The die has placement grooves and mounting screw holes on both the front and back sides. The pressure plate is connected to the die by screw two screws screwed into the mounting screw holes. The pressure plate and placement grooves are matched. The lower end face of the die has a fixing screw hole. The upper end of screw three screws is screwed into the fixing screw hole. The upper end face of the die has a punch through hole. A punch slides in the punch through hole.

[0011] Each of the placement slots has a limiting through hole on its inner sidewall.

[0012] The front end of the punch is a blind hole with a cutting edge, and the front end of the side wall of the punch is provided with a notch.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This invention features a simple structure and convenient operation, enabling punching at different locations on the same product while reducing operational difficulty and labor intensity. Precise positioning via the product's raised cylinders ensures stability during the punching process and improves punching accuracy. Furthermore, it is suitable for small-batch production, enhancing the portability and stability of rubber product punching operations, reducing production costs, and demonstrating significant economic benefits and practicality.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0025] A punching fixture for rubber products includes a base 1, a bracket 2, a punch 4, a pressure plate 5, and a punch 8. The upper end of the base 1 is detachably and fixedly connected to the lower end of the vertically arranged bracket 2. The upper end of the bracket 2 is detachably and fixedly connected to the punch 4. The front and back sides of the punch 4 are respectively detachably and fixedly connected to the corresponding pressure plates 5. The punch 8 slides inside the punch 4.

[0026] One end of the upper surface of the base 1 is provided with a square hole 1-1, and the lower end of the bracket 2 is provided with a square protrusion 2-1. The square protrusion 2-1 is inserted into the square hole 1-1 and then tightened by a screw 3 screwed into the threaded through hole 1-2 on the side wall of the square hole 1-1, thereby realizing the installation and positioning of the bracket 2.

[0027] The upper end of the bracket 2 is provided with an integrally formed horizontal boss 2-2 for placing the punch 4; the middle part of the horizontal boss 2-2 is provided with a U-shaped groove 2-3, and a screw 7 is provided in the U-shaped groove 2-3 for fixing the punch 4.

[0028] The horizontal boss 2-2 has installation clearance 2-4 on both sides for product installation clearance.

[0029] The die 4 has placement grooves 4-1 and mounting screw holes 4-2 on both its front and back sides. The pressure plate 5 is connected to the die 4 by screws 6 screwed into the mounting screw holes 4-2. The pressure plate 5 and placement grooves 4-1 are fitted together to achieve product clamping. The lower end face of the die 4 has a fixing screw hole 4-8. The upper end of screw 7 is screwed into the fixing screw hole 4-8 to fix the die 4. The width of the rectangular groove 4-1 is matched with the size clearance of the product for coarse positioning. The depth of the rectangular groove 4-1 is 0.1mm smaller than the height of the product to ensure the clamping amount of the pressure plate 5. The upper end face of the die 4 has a punch through hole 4-4 that extends through its thickness direction. A punch 8 slides in the punch through hole 4-4 to ensure the vertical movement of the punch 8. The punch 8 punches the product through the punch through hole 4-4.

[0030] Each of the placement slots 4-1 has a limiting through hole 4-3 on its inner sidewall. The size of the limiting through hole 4-3 is matched with the clearance of the protruding cylinder of the product. The three protruding cylinders of the product are inserted into the corresponding limiting through holes 4-3 respectively to accurately position the product.

[0031] The front end of the punch 8 is a blind hole with a cutting edge, and the front end of the side wall of the punch 8 is provided with a notch for cleaning up the residual material after punching.

[0032] When using this invention, first install the product in the placement groove 4-1 on the front of the die 4 and press it firmly with the corresponding pressure plate 5. Then, fix the die 4 to the horizontal boss 2-2 of the bracket 2 with screws 7. Use the punch 8 to punch holes in the product. After punching one side, remove the product from the die 4, loosen screws 7, rotate the die 4 180 degrees, and then fix the die 4 again with screws 7. Fix the product in the placement groove 4-1 on the back of the die 4 and press it firmly with the corresponding pressure plate 5. Use the punch 8 to punch holes on the other side of the product. Clean the excess material in the punch 8 after punching from the notch on the side of the blind hole of the punch.

[0033] The punch die 4 comes in various models, differing in the distance between the punch through holes 4-4 and the diameter of the punch through holes 4-4. The distance between the punch through holes 4-4 is between 8-130mm, and the diameter of the punch through holes 4-4 is between 4-8mm. The punching range of the selectable punch 8 is between 2-5mm.
