Description

Technical Field

[0001] This application belongs to the technical field of automotive sealing strip production, and particularly relates to a punching and cutting assembly for sealing strips that can extend the service life of cutting knives. Background Art

[0002] A notch needs to be cut at one or both ends of the automotive sealing strip, and finally cut into a shape that matches the installation groove of the automotive sealing strip and installed at the corresponding position of the vehicle. The existing cutting assembly basically drives a cutting knife along the cutting trajectory by a moving module to cut a notch from the automotive sealing strip. However, for this kind of cutting, the cutting knife needs to turn to cut, and the cutting knife is prone to deformation at the turning point, resulting in wear of the cutting edge of the cutting knife, and thus reducing the service life of the cutting knife.

[0028] The technical solutions of the present application will be described in detail below with reference to the drawings and in combination with the embodiments Embodiment

[0029] This embodiment provides a sealing strip punching assembly for extending the service life of a cutting tool, including the following components located on a workbench:

[0030] A feeding and positioning section 10, which includes a positioning seat 101. A positioning groove 102 for accommodating and fixing the product is provided on the positioning seat 101. A guiding rod 103 for guiding the product is arranged on the upper surface of the positioning seat 101. The positioning seat 101 is used to support the tail end of the automotive sealing strip, and the guiding rod 103 is used to support the middle section of the automotive sealing strip. Below the guiding rod 103 is for mating and inserting with the automotive sealing strip;

[0031] A punching mechanism 20, which punches the head end of the automotive sealing strip. The punching mechanism 20 includes a machine frame 201, a supporting assembly 202, and a knife assembly 203. The supporting assembly 202 is used to support and fix the product to be punched. The supporting assembly 202 is installed on one side below the machine frame 201 and corresponds to the position of the feeding and positioning section, with one supporting the tail end and the other supporting the head end. The knife assembly 203 is installed below the machine frame 201 and can punch the product located on the supporting assembly 202;

[0032] Specifically, the knife assembly 203 includes a cylinder 203.1, a connecting seat 203.2, a punching block 203.3, a punching knife 203.4, and a knife fixing profile 203.5. The cylinder 203.1 is installed on the machine frame 201, the punching block 203.3 is installed at the lower end of the cylinder 203.1, the punching knife 203.4 is located in the direction of the knife fixing profile 203.5 close to the punching block 203.3. A knife groove cavity 203.5 allowing the punching action of the punching knife 203.4 is provided on the knife fixing profile 203.5. A lower conical surface 203.6 for changing the position of the punching knife during up and down movement is provided on the side surface of the punching block 203.3. An upper conical surface 203.7 parallel to the lower conical surface 203.6 is provided on the handle of the punching knife 203.4. When the cylinder 203.1 drives the punching block 203.3 to move downward, the punching knife 203.5 can be extruded through the lower conical surface 203.6, so that the punching knife 203.5 approaches the automotive sealing strip for punching.

[0033] To improve the service life of the punching knife, the punching knife 203.5 is integrally in an inverted U shape and can punch an inverted U-shaped notch or an L-shaped notch. A V-shaped cutting edge 203.8 is provided in the punching direction of the punching knife 203.5. The center of the V-shaped cutting edge of the punching knife 203.5 coincides with the center line of the punching knife 203.5. With such a design of the punching knife 203.5, firstly, a notch can be directly cut out from the automotive sealing strip in one go, without the need for two cutting knives to be combined, nor for a single cutting knife to cut in a curved manner. Secondly, the punching knife 203.5 designed in this way has a longer service life and is durable.

[0034] As an embodiment of the present utility model, in addition to the above structure, an installation groove 203.9 is provided on the handle of the punching cutter 203.5. A guiding member 211 is arranged in the installation groove 203.9. The guiding member 211 abuts against the installation groove 203.9. The guiding member 211 cooperates with the punching cutter 203.5 to guide the punching cutter 203.5 to move in a set direction. The other end of the guiding member 211 is fixed on the punching block 203.3 to strengthen the connection of the punching cutter 203.5 while not hindering the movement of the punching cutter 203.5. A connection groove 212 is provided on the outer side surface of the punching block 203.5. The guiding member 211 is L-shaped, and one end of its L-shaped end is fixed in the connection groove 212 to enhance the connection stability.

[0035] As an embodiment of the present utility model, in addition to the above structure, the support assembly 202 includes a vertical rod 202.1, a tool holder 202.2, and a sealing strip support seat 202.3. The vertical rod 202.1 is connected to the connection seat 203.2. The air cylinder 203.1 drives the connection seat 203.2 to move up and down, which is convenient for cooperating with the punching action of the punching cutter 203.5. The connection seat 203.2 and the vertical rod 202.1 can be connected by adjusting bolts to conveniently adjust the position of the connection seat 203.2. The tool holder 202.2 is installed on the vertical rod 202.1 to provide a working surface for the punching cutter 203.5. The sealing strip support seat 202.3 is installed on the side surface of the tool holder 202.2 close to the punching cutter 203.5.

[0036] When the product of this application is working:

[0037] Insert the automotive sealing strip line into the positioning groove of the feeding and positioning section, and then insert it onto the sealing strip support seat through the guiding rod. The air cylinder is started to drive the punching part downward. At this time, the punching cutter will be extruded to move towards the sealing strip support seat direction. The punching cutter moves linearly along the tool groove cavity, and finally cuts the automotive sealing strip located on the sealing strip support seat. After the cutting is completed, the air cylinder drives the punching part to move upward, and the punching cutter resets, and the automotive sealing strip can be taken out.

[0038] Taking the above ideal embodiment based on this application as an inspiration, through the above description, relevant staff can completely make various changes and modifications without departing from the technical idea of this application. The technical scope of this application is not limited to the content in the specification, and its technical scope must be determined according to the scope of the claims.
