Abstract
Description
Technical Field
[0001] This application relates to the field of brake technology, and specifically discloses a damage-resistant brake body. Background Technology
[0002] This invention is a structure for reinforcing and repairing the complex large-sized damage to the cast iron parts of the 250T scissor machine brake body. It mainly uses metal materials to reinforce and strengthen the cast iron shell.
[0003] Due to its long service life, the 50T shearing machine's brake spring seat has been subjected to heavy loads and strong impacts for an extended period, resulting in severe damage to the brake body, with two punctures and multiple cracks. The equipment can no longer operate normally, rendering the shearing machine unusable.
[0004] The 250T scissor machine is a key piece of equipment in leaf spring production. This equipment has high repair and reuse value. Its brake body housing is made of gray cast iron. If the brake housing spring seat cracks, brake failure and spindle jamming will occur. A cracked brake housing also affects the sealing effect of the piston cylinder, directly impacting production. Damaged housings are generally scrapped, while purchasing new ones is expensive and has a long production cycle, requiring mold making, sand casting, gear hobbing, and precision machining. Welding repair is currently not feasible due to the lack of suitable cast iron welding technology, and even if welding is used, the welding cycle is lengthy and impact resistance cannot be guaranteed. Existing technologies cannot meet production and repair needs, and other repair methods are not effective enough to achieve truly rapid repair.
[0005] Therefore, it is imperative to study the damage resistance of the cast iron parts of the brake body. Thus, the inventors proposed a damage-resistant brake body. Utility Model Content
[0006] The purpose of this invention is to solve the problem that the traditional brake body is severely damaged due to long-term exposure to heavy loads and strong impacts.
[0007] To achieve the above objectives, this utility model provides the following basic solution.
[0008] A damage-resistant brake body includes a brake body, a brake pressure plate mounted on one side of the brake body, a friction plate connected to the brake pressure plate, a spring seat on the brake body, a compression spring bolt disposed in the spring seat, and a piston mounted on the brake body.
[0009] A pad is provided at the connection between the piston and the spring seat to reduce damage to the end face of the spring seat. The pad is circular. The piston has an annular protrusion for fixing the pad. After the spring seat and the piston are installed, the compression bolt passes through the piston, the pad and the spring seat respectively.
[0010] The principle and effect of this basic scheme are as follows:
[0011] 1. Compared with existing technologies, this device has a simple structure and ingenious design. This device is designed to improve the damage resistance of the cast iron parts of the 250T scissor machine brake body. The core is: adding a pad to the end of the spring seat in the vulnerable position, so that the piston no longer directly contacts the end of the spring seat. This setting makes the end of the spring seat more resistant to damage in the vulnerable position. Since the addition of the pad increases the overall thickness, the thickness of the piston needs to be changed. For this reason, the pad is set as a ring, and the piston has an annular protrusion for fixing the pad. Using the annular protrusion to fix the pad not only increases the thickness of the piston, but also helps to fix the pad and ensure the sealing effect.
[0012] 2. Compared with existing technologies, this device addresses the vulnerable point. This device is a 250T scissor brake, and the vulnerable point is the end of the spring seat. The cause of damage is that the spring seat and the piston housing are in long-term contact and wear occurs during device operation. Therefore, a pad is installed starting from the end of the spring seat. The pad isolates the end of the spring seat from the piston, and the piston thickness is increased by using the pad to ensure effective sealing. This device solves the problem that traditional brake bodies are subjected to heavy loads and strong impacts for a long time, resulting in severe damage to the brake body.
[0013] Furthermore, the piston has protrusions at both ends, and the protrusions have connecting holes that communicate with the spring seat. The compression spring bolt passes through the connecting holes and is installed in the spring seat.
[0014] Furthermore, one end of the compression spring bolt is placed outside the piston and threadedly connected to the piston, while the other end of the compression spring bolt passes through the spring seat and is placed in the brake pressure plate. Attached Figure Description

Obviously, the accompanying drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.
[0016] Figure 1 A schematic diagram of the structure of a damage-resistant brake body according to an embodiment of this application is shown;
[0017] Figure 2 A side view of a piston in a damage-resistant brake body according to an embodiment of this application is shown. Detailed Implementation
[0018] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.
[0019] The reference numerals in the accompanying drawings include: brake body 1, brake pressure plate 101, brake main body 102, piston 103, pad 104, spring bolt 105, friction disc 106, spring seat 107, and annular protrusion 108.
[0020] Implementation, for example Figure 1 and Figure 2 As shown:
[0021] A damage-resistant brake body 1 includes a brake body 102, a brake pressure plate 101 mounted on the right side of the brake body 102, a friction plate 106 connected to the brake pressure plate 101, a spring seat 107 opened on the brake body 102, a compression spring bolt 105 disposed in the spring seat 107, and a piston 103 mounted on the brake body 102.
[0022] Specifically: Generally speaking, the brake pressure plate 101 is fixed using fasteners, and then the brake body 102 is installed on the brake pressure plate 101. Since the brake body 102 is installed on the brake pressure plate 101, the position of the spring seat 107 is indicated. For example... Figure 1 As shown, a piston 103 is installed on the right side of the brake body 102.
[0023] A pad 104 is provided at the connection between the piston 103 and the spring seat 107 to reduce damage to the end face of the spring seat 107. The pad 104 is annular. An annular protrusion 108 is provided on the piston 103 to fix the pad 104. After the spring seat 107 and the piston 103 are installed, the compression bolt 105 passes through the piston 103, the pad 104 and the spring seat 107 respectively. The piston 103 has protrusions at both ends, and the protrusions have connecting holes that communicate with the spring seat 107. The compression bolt 105 passes through the connecting holes and is installed in the spring seat 107. One end of the compression bolt 105 is placed outside the piston 103 and threadedly connected to the piston 103. The other end of the compression bolt 105 passes through the spring seat 107 and is placed in the brake pressure plate 101.
[0024] Specifically: This device is a 250T scissor brake, and the vulnerable point is the end of the spring seat 107. The cause of damage is that the spring seat 107 is in long-term contact with the piston 103 housing and wears down as the device is started. Therefore, a pad 104 is installed at the end of the spring seat 107 to isolate the end of the spring seat 107 from the piston 103, thus quickly reducing the vulnerability of the end of the spring seat 107. Then, due to the addition of the pad 104, the overall thickness increases. Therefore, an annular protrusion 108 is installed on the piston 103. The thickness of the annular protrusion 108 is equal to the thickness of the pad 104. Since the pad 104 is annular, it is fitted onto the annular protrusion 108 to achieve normal installation of the piston 103.
[0025] Specific implementation process:
[0026] According to such Figure 1 As shown, during normal installation, after the piston 103 is fitted, the spring bolt 105 is inserted through the connection hole. After the spring bolt 105 is fully inserted, the spring bolt 105 located outside the piston 103 can be secured with a nut.
[0027] The core of this case is that a pad 104 is added to the end of the spring seat 107 at a vulnerable location, so that the piston 103 no longer directly contacts the end of the spring seat 107, thereby improving the damage resistance of the device.
[0028] This device solves the problem that the traditional brake body 1 is subjected to heavy loads and strong impacts for a long time, which causes serious damage to the brake body 1.
[0029] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
