Description

Technical Field

[0001] This utility model relates to the technical field of automotive brake component processing equipment, specifically to a high-density barbed steel backing mechanism and a barbed steel backing device, and more particularly to a high-density barbed steel backing mechanism and a barbed steel backing device for surface treatment of brake disc steel backing, which is particularly suitable for scenarios where high-density barbs are processed on the surface of steel backing to enhance adhesion with friction materials. Background Technology

[0002] In automotive braking systems, the adhesion between the steel backing and the friction material directly affects braking performance and service life. Traditional steel backing burr forming processes have two major technical bottlenecks: 1. Low burr density: Using fixed molds for stamping results in large burr spacing, leading to insufficient adhesion; 2. Low changeover efficiency: Processing different models of steel backing requires changing the entire set of molds, with each changeover taking more than 30 minutes. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this application proposes to provide a high-density barbed bar mechanism and steel back barbed bar equipment, which can achieve ultra-high density barbed barbing on the back surface, quick replacement of different types of steel backs without tools, and precise control of the start and stop position of individual barbed points.

[0004] This application discloses a high-density barbed wire mechanism, comprising:

[0005] Cylinder seat;

[0006] A tool holder, which is connected to the cylinder seat, and the tool holder is provided with a tool holder shaft;

[0007] At least 5 tool holders, the tool holders being arranged along the tool holder axis and rotatably engaged with the tool holder axis;

[0008] A cutting tool, wherein the cutting tool is disposed in each tool holder;

[0009] A cylinder (corresponding to each of the tool sleeves) is disposed on the cylinder seat;

[0010] A spring that connects the tool holder and the tool sleeve.

[0011] Furthermore, the tool holder is provided with a through hole, and a small copper sleeve is provided in the through hole. The cylinder push rod passes through the small copper sleeve and contacts the tool holder.

[0012] Furthermore, the cylinder's push rod pushes the tool holder to rotate around the tool holder shaft through the through hole, causing the tool to disengage from or contact the steel back machining surface.

[0013] Furthermore, the number of the blade sheaths is 5, 7, 11, 13, or 15.

[0014] A steel-backed barbed wire device includes the aforementioned high-density steel-backed barbed wire mechanism.

[0015] Compared with the prior art, this application has at least the following beneficial effects:

[0016] 1. The number of tool holders in this application can be selected as 5, 7, 11, 13 or 15 according to actual processing needs, which can achieve high-density or even ultra-high-density processing and achieve a puncture density of 5-7 points / cm².

[0017] 2. This application uses a PLC program to control the cylinder's movement, reducing the changeover time from 30 minutes to 10 seconds;

[0018] 3. Each tool holder in this application can be independently controlled to achieve adaptive machining and generate arbitrary burr patterns, such as array / interlaced / gradient distribution, etc.; a single damaged tool holder can be replaced independently, reducing maintenance costs by 70%.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] A high-density piercing mechanism includes: a cylinder seat 24; a blade holder 25 connected to the cylinder seat 24, the blade holder 25 having a blade holder shaft 29, a through hole, and a small copper sleeve 26 disposed within the through hole, the cylinder 34 push rod passing through the small copper sleeve 26 and contacting the blade sleeve 27; at least five blade sleeves 27, the number of which is 5, 7, 11, 13, or 15. This embodiment shows five blade sleeves 27. Arranged along the tool holder axis 29 and rotatably engaged with the tool holder axis 29; cylinder 34, the cylinder 34 being disposed on the cylinder seat 24 corresponding to each of the tool sleeves 27; cutting tool 28, the cutting tool 28 being disposed in each tool sleeve 27; the push rod of the cylinder 34 pushes the tool sleeve 27 to rotate around the tool holder axis 29 through the through hole, so that the cutting tool 28 disengages from or contacts the steel back machining surface; spring 50, the spring 50 connecting the tool holder 25 and the tool sleeve 27.

[0024] When the cylinder 34 push rod extends, it pushes the tool sleeve 27 to rotate around the tool holder shaft 29, causing the tool 28 to disengage from the steel back machining plane (disabled state); Spring 50 reset mechanism: When the cylinder 34 push rod retracts, the spring 50 pulls the tool sleeve 27 back to the initial position, and the tool 28 contacts the machining plane (activated state).

[0025] A steel-backed barbed wire device includes the aforementioned high-density steel-backed barbed wire mechanism.

[0026] Work process:

[0027] During processing, the PLC sends commands to retract the push rods of cylinders 1, 3, and 5, which in turn reset the corresponding tool holders under spring action, allowing the tool to contact the steel back surface. Meanwhile, the push rods of cylinders 2 and 4 extend, pushing the tool holders to rotate 25°, lifting the tool to avoid the processing area. This achieves selective piercing. Example

[0028] The difference from Example 1 is that the number of blade sheaths is 13, achieving a puncture density of 5-7 points / cm².

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
