Description

Technical Field

[0001] The present application relates to the technical field of hot pressing machines, and in particular to a friction plate hot pressing molding machine. Background Art

[0002] Friction pads are also called brake pads. They are steel backing plates with friction materials. By pressing the brake disc that rotates with the wheel, the brake pads can generate friction to slow down or stop the vehicle. In the braking system of a car, brake pads are very important safety parts and play a critical role. Brake pads determine the effectiveness of braking and are closely related to the safety of the car.

[0003] In the prior art, the existing isotropic hot press puts the friction material into the die, drives the punch through the hydraulic cylinder to extrude the friction material in the die, and heats the friction material and the steel back at the same time, so that the two are pressed together at a certain temperature and time. However, the current hot press usually heats the friction material and the steel back through the upper die heating plate and the lower die heating plate, and the heating uniformity is poor. When the connection between the friction material and the steel back reaches the pressing temperature, the temperature on the outside will be higher than the pressing temperature, so that the friction material, especially the external friction material, has a certain viscosity after heating. The existing friction plate isotropic hot press usually uses manual feeding of the steel back and material removal of the hot-pressed friction plate. The outer part of the friction material is tightly attached to the inner wall of the die under the dual effects of extrusion and heating, which causes certain obstacles to material removal. At the same time, the friction material on the surface may partially adhere to the inner wall of the die and fall off, affecting the subsequent hot pressing of the friction plate and causing adverse effects on the quality of the friction plate.

[0049] In the present application, the column 2 is fixedly arranged on the top of the machine base 1, and the first driving member 6 drives the workbench 3 to move up and down along the axial length direction of the column 2, driving the punch assembly installed on the workbench 3 to approach the die bracket 4, so that the output end of the punch assembly is fed inside the die body 10 to extrude the friction material in the die body 10. The die bracket 4 is slidably connected with the die body bracket 11, so that the staff can collect the finished product after the die pressing operation. A heating member 12 is arranged between the die body bracket 11 and the die body 10, which can preheat the inside of the die body 10 to avoid cracks in the friction material due to instantaneous thermal stress on the friction material. The second driving member 7 can drive the die bracket 4 to slide on the column 2, so that the punch assembly can extrude the friction material and other auxiliary parts in the die body 10 again after one die pressing, thereby ensuring the structural strength of the finished product.

[0050] like Figure 4As shown, it is feasible that the die body bracket 11 in the present application slides back and forth along the length direction of the die bracket 4. Preferably, the die body bracket 11 in the present application is two, wherein when the first die body bracket 11 is in die pressing, the second die body bracket 11 is in a preparatory state; when the first die body 10 is die pressing, it slides along the length direction of the die bracket 4 to the side away from the second die body bracket 11, at which time, the second die body bracket 11 starts die pressing, and the first die body bracket 11 is in a preparatory state. The preparatory state mentioned above includes loading and unloading.

[0051] The number of the columns 2 is at least three. The columns 2 are evenly arranged around the machine base 1 , and the lower parts of the columns 2 are fixedly connected to the peripheral side surface of the machine base 1 .

[0052] The pillars 2 in the present application not only provide installation positions for the workbench 3, the die bracket 4 and the top plate 5, but also constrain the first driving member 6 and the second driving member 7 to drive the workbench 3 and the die assembly to move in the vertical direction. Preferably, there are four pillars 2 in the present application. The purpose of such a setting is that when the male die assembly and the die body 10 and the top plate 5 in the present application perform a material pressing operation, the die bracket 4, the workbench 3 and the top plate 5 can be prevented from twisting, thereby ensuring a stable pressing operation of the friction plate.

[0053] Implementable, such as Figure 8 As shown, the connection between the column 2 and the top plate 5 can be set as a threaded section, and the staff can install an external drive motor to drive the column 2 to rotate, so that the top plate 5 can move from top to bottom spontaneously. During this process, the template base 9 located at the bottom of the top plate 5 moves downward together and squeezes with the top of the die body 10. The friction material is squeezed together by the upward driving force of the first driving member 6 and the second driving member 7 and the downward force of the top plate 5, so that the pressed part is subjected to stable pressure, thereby ensuring the quality of the pressed part.

[0054] A first die cavity 101 having the same size as the finished product is provided inside the die body 10 . In horizontal projection, the cross-sectional profile of the first die cavity 101 is consistent with the cross-sectional profile of the punch 25 . Hanging holes 102 are provided through the periphery of the die body 10 . Positioning holes 103 are symmetrically provided on both sides of the hanging holes 102 along the width direction of the die body 10 .

[0055] In the above scheme, the first die cavity 101 is used to store the friction material, providing a sealed space when the male die assembly and the die body are squeezed against each other, ensuring that the friction material is subjected to a stable squeezing force. In addition, the cross-sectional profile of the first die cavity 101 is consistent with the cross-sectional profile of the punch 25 to avoid leakage of the friction material when the punch 25 is displaced along the height direction of the first die cavity 101, while ensuring good contact between the punch 25 and the first die cavity 101. The hoisting hole 102 is provided for the staff to take the die body 10. If feasible, the hoisting hole 102 can be a threaded hole. The positioning hole 103 is provided to ensure that when the die body 10 is displaced toward the top plate 5, the template can be in good contact with the upper end surface of the die body 10. If feasible, a positioning pin is fixedly provided on the lower end surface of the template corresponding to the positioning hole 103.

[0056] The punch assembly includes a punch bracket 20, an isobaric pressure balancer 21, a punch seat 22, a second heat insulation board 23, a die handle 24, a punch 25, a heating tube 26 and a thermocouple 27; the punch bracket 20 is slidably arranged on the table surface of the workbench 3, and the sliding path of the punch bracket 20 is consistent with the sliding path of the die body 10, and the body of the punch bracket 20 is arranged in a missing part for installing the punch assembly, and the missing part is penetrated by a through hole 201 from top to bottom; the punch seat 22 is placed inside the punch bracket 20, and the bottom area of ​​the punch seat 22 is larger than the aperture of the through hole 201; the isobaric pressure balancer 21 is arranged at the lower part of the punch bracket 20, and its working The working end passes through the through hole 201 and abuts against the bottom of the punch seat 22; the second heat insulation plate 23 is fixedly arranged in the middle of the punch seat 22; the punch seat 22 is fixedly provided with a die handle 24, which is arranged vertically and extends to one side of the die body 10; the punch 25 is fixedly arranged on the top of the die handle 24, and the cross-sectional profile of the punch 25 in horizontal projection is consistent with the cross-sectional profile of the die handle 24; the heating tube 26 is vertically arranged inside the die handle 24, and its working end extends to the inside of the punch 25; the thermocouple 27 is vertically spaced on both sides of the heating tube 26, and its working end extends to the inside of the punch 25, and the heating tube 26 is electrically connected to the thermocouple 27.

[0057] In the above scheme, the punch bracket 20 is used to install the punch seat 22, and the through hole 201 is set so that the output end of the isobaric pressure balancer 21 abuts against the punch seat 22. When the workbench 3 is vertically displaced, the punch 25 on the punch seat 22 is driven to pass through the first die cavity 101 and squeeze the friction material and the steel back plate. In this process, the isobaric pressure balancer 21 balances the pressure of the punch 25 on the friction material and the steel back plate in each first die cavity 101 in real time. The heating tube 26 and the thermocouple 27 arranged inside the die handle 24 can continuously heat the punch 25. The punch 25 and the heating plate 12 on the inner side of the die body bracket 11 heat the friction material together to ensure that the friction material is heated evenly, so as to reduce the thermal stress on the friction material, thereby ensuring its stable friction performance.

[0058] Implementable, such as Figure 7 As shown, in the present application, the end of the sliding path of the punch bracket 20 on the workbench 3 is gently tilted upward from the horizontal. When the first driving member 6 drives the workbench 3 to slide upward and completes the die pressing, the workbench 3 and the die bracket 4 are reset downward together, and then the punch bracket 20 and the die body bracket 11 that has completed the die pressing operation slide toward the preparation station. During this process, the punch part on the punch bracket 20 can lift the pressed part to separate the pressed part from the die body 10, so that the staff can collect the pressed part.

[0059] In the present application, the transmission method of the die body bracket 11 and the punch bracket 20 on the die body bracket 11 and the workbench 3 can be one or more of gear transmission, chain transmission, and belt transmission (crawler, V-belt).

[0060] A fourth driving member 30 is disposed at the bottom of the second driving member 7 . The output end of the fourth driving member 30 abuts against the bottom of the second driving member 7 , and can drive the second driving member 7 to move up and down along the axial length direction of the column 2 .

[0061] In the above scheme, the fourth driving member 30 plays a secondary role in driving the second driving member 7 to prevent the extrusion force on the friction material in the die body 10 from failing to meet the molding requirements when the second driving member 7 drives the die bracket 4. In addition, the setting of the fourth driving member 30 also reduces the operating pressure of the second driving member 7 and extends the service life of the second driving member 7.

[0062] The two side frames of the die body bracket 11 along the width direction thereof are provided with clamping cylinders 40, the clamping cylinders 40 are arranged at intervals from the fourth driving member 30, and the output end faces of the clamping cylinders 40 abut against the two side faces of the die body 10 along the length direction thereof. The purpose of such arrangement is that when the die body bracket 11 is displaced on the die bracket 4, the clamping cylinders 40 can stably support the die body bracket 11, thereby improving the stable connection between the die body bracket 11 and the die bracket 4.

[0063] In order to facilitate the horizontal sliding of the die body bracket 11 on the frame of the die bracket 4, a slide rail 41 is arranged on the inner side of the die bracket 4 along its width direction, and a slide groove 111 is opened on both sides of the frame along its length direction, and the groove wall of the slide groove 111 is slidably connected to the surface of the slide rail 41.

[0064] Implementable, such as Figure 4 As shown, the extension path of the third driving member 8 is consistent with the length direction of the die bracket 4. The third driving member 8 drives the die body bracket 11 to move toward the outside of the die bracket 4, which is convenient for the staff to collect the finished products and convenient for the external feeding device to add materials to the die body 10 again, thereby realizing the pressing cycle of the friction plate.

[0065] It is feasible that the cross-sectional profile of the slide rail 41 is consistent with the cross-sectional profile of the slide slot 111 to ensure the stability of the relative displacement between the die body bracket 11 and the die bracket 4. Preferably, the cross-sectional profile of the slide rail 41 is a trapezoidal structure with a diameter gradually increasing from the outside to the inside.

[0066] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other. Each embodiment focuses on the differences from other embodiments.

[0067] The above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit the present application. Although the present application has been described in detail with reference to the aforementioned embodiments, a person of ordinary skill in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some or all of the technical features thereof may be replaced by equivalents.
