Description

Technical Field

[0001] This invention relates to the field of brake shoe manufacturing technology, and particularly to a brake shoe manufacturing equipment. Background Technology

[0002] High-friction brake shoes are an important component of railway freight car braking systems. In related technologies, high-friction brake shoes are mostly produced through powder pressure molding. The production process involves placing the pre-formed shoe backing into a molding cavity and adding powder into the cavity. The powder is then extruded to form friction elements, which are then tightly bonded to the shoe backing to form the brake shoe.

[0003] However, the working environment during the production of brake shoes is extremely harsh, generating significant noise and undergoing cold and hot pressing processes during molding, further exacerbating the production environment. This reduces worker efficiency and can easily impact their health. Summary of the Invention

[0004] This invention provides a brake shoe production equipment to reduce the workload of workers and improve the production efficiency of brake shoes.

[0005] This invention provides a brake shoe production equipment, comprising: a forming press having a mold assembly, the mold assembly being used to press the back of the brake shoe and powder to form a brake shoe; A visual inspection device is installed at the inspection station to inspect the quality of the brake shoes; A first robot, used to grip the nose of the tile back, for placing the tile back onto the lower mold of the mold assembly, and for transferring the pressed brake shoe from the forming cavity to the inspection station; and A powder addition system includes a second robot that adds powder to the molding cavity containing the tile back after the first robot places the tile back in the molding cavity.

[0006] In one embodiment, the forming press further includes a press body, a movable base, and a drive frame, wherein the movable base and the drive frame are both mounted on the press body, and the drive frame is located above the movable base; The mold assembly includes a lower mold, a middle mold, and an upper mold, wherein the middle mold is connected to the lower mold to form the molding cavity, the lower mold is mounted on the movable base, and the upper mold is mounted below the drive frame; The movable seat is used to drive the middle mold and the lower mold to move, and the movable seat can move between the filling station and the molding station. When the movable seat moves to the filling station, the first robot and the second robot can add the back of the tile and the powder to the molding cavity respectively. When the movable seat moves to the molding station, the drive frame can drive the upper mold to move downward so that the back of the tile and the powder in the molding cavity form a brake shoe.

[0007] In one embodiment, the powder adding system further includes a pouring mechanism disposed on one side of the molding press. The pouring mechanism includes a funnel, and the second robot is used to add powder to the funnel. When the pouring mechanism pours powder, the moving seat moves to the filling station, and the outlet of the funnel faces downward toward the top of the molding cavity. A valve is provided at the outlet of the funnel.

[0008] In one embodiment, the material pouring mechanism further includes a guide rail on which a driving unit is movably mounted. The driving unit is capable of moving along the guide rail and is connected to the funnel to move the funnel above or below the filling station. The driving unit is also capable of driving the funnel to rotate and sway. In one embodiment, the second robot includes a first gripper for gripping a material box located at a first storage station, wherein the amount of powder contained in the material box is equal to the amount of powder required for one brake shoe.

[0009] In one embodiment, the first robot is provided with a second gripper, the second gripper including a positioning part and a clamping part. The positioning part is used to be positioned by inserting into the tile nose positioning hole of the tile back, and the clamping part is used to be inserted into the tile nose insertion hole of the tile back after positioning to clamp the tile back. The tile nose has at least two tile nose insertion holes.

[0010] In one embodiment, the second robot is further provided with a cleaning mechanism, which is used to clean the molding cavity before the first robot places the tile back into the molding cavity. In one embodiment, the mold assembly is connected to a temperature control device for controlling the temperature inside the molding cavity at the molding temperature during extrusion molding by the molding press.

[0011] In one embodiment, a finished product storage station is also provided on one side of the forming press, and the first robot is also used to grab the qualified brake shoes to the finished product storage station after the brake shoes are qualified in the inspection station.

[0012] In one embodiment, both the first robot and the second robot are six-axis robots.

[0013] Compared with existing technologies, the advantages of this invention are that the first robot can be used to feed the brake shoe back, while the second robot of the powder adding system can be used to add powder, eliminating the need for manual material addition. After the material in the forming cavity is extruded and shaped using the forming press, the first robot can remove the produced brake shoe and place it at the inspection station. The brake shoe is then inspected by a vision inspection device, thus reducing the workload of the inspection process. This improves the production efficiency of brake shoes while reducing the missed inspection rate, and also reduces the workload of workers, eliminating the need for them to handle the high-risk forming press and improving their working environment.

[0017] The invention will now be further described with reference to the accompanying drawings.

[0018] Combination Figures 1-6 As shown, the present invention provides a brake shoe production equipment, which includes a forming press 100, a vision inspection device 501, a first robot 200, and a powder addition system.

[0019] The forming press 100 has a mold assembly 110. After adding the back of the brake shoe 910 and related manufacturing powder to the forming cavity of the mold assembly 110, the forming press 100 can perform cold pressing and hot pressing of the powder in the forming cavity, thereby making the powder into a friction body 920 connected to the back of the brake shoe 910.

[0020] When the brake shoe production equipment is working, the controller of the equipment first controls the first robot 200 to grab the back of the brake shoe 910 and place it on the upper mold 113 of the mold assembly 110. Then, the second robot 300 of the powder adding system adds powder to the forming cavity where the back of the brake shoe 910 is placed. After the back of the brake shoe 910 and the powder have been added, the controller controls the forming press 100 to control the template assembly to perform cold pressing and hot pressing processes to form the brake shoe. After the brake shoe is formed, the first robot 200 can remove the produced brake shoe from the mold assembly 110 and move it to the inspection station. The vision inspection device 501 at the inspection station performs visual inspection on the produced brake shoe to determine its production quality.

[0021] In other words, the brake shoe production equipment provided in this application can essentially automate the entire brake shoe production process, thereby greatly reducing the labor intensity of workers, avoiding accidental bumps during handling, and eliminating the need for workers to contact the forming press 100, thus reducing the risk of injury to workers during the operation of the forming press 100. Simultaneously, it can also prevent a decrease in production efficiency due to worker discomfort, allowing for sustained high production efficiency during brake shoe production.

[0022] In this application, the first robot 200 moves the tile back 910 and the brake shoe by gripping the tile nose of the tile back 910. See also Figure 5 as well as Figure 6As shown, the center of the brake shoe back 910 protrudes outward to form a brake shoe nose structure. When placing the brake shoe in the molding cavity of the mold assembly 110, the first robot 200 often clamps the brake shoe back 910 from the concave side of the brake shoe nose, so that when the brake shoe back 910 is placed in the molding cavity of the mold assembly 110, the concave structure of the brake shoe back 910 faces upward, while the convex structure of the brake shoe nose faces downward. This allows the powder to fall onto the inner surface of the brake shoe back 910 when the powder adding system adds powder to the molding cavity, thereby causing the molded friction body 920 to adhere to the inner surface of the brake shoe back 910.

[0023] In some implementations, the design of the mold assembly 110 can prevent the powder from contacting the inner surface of the brake shoe nose during the extrusion process. This ensures that after the brake shoe is formed, the inner surface of the brake shoe nose is not obstructed by the friction body 920, facilitating gripping by the first robot 200.

[0024] It is understandable that, compared to brake shoes where the entire inner side of the back 910 is covered with friction body 920, this application makes the inner side of the nose of the brake shoe not have friction body 920 attached during molding, so the brake shoe can be removed by the original method of clamping the nose of the brake shoe.

[0025] See Figure 1 as well as Figure 2 As shown, in some implementations, the molding press 100 includes a press body, a movable seat 120 and a drive frame 130. The movable seat 120 and the drive frame 130 are both mounted on the press body, and the drive frame 130 is located above the movable seat 120.

[0026] The mold assembly 110 includes a lower mold 111, a middle mold 112 and an upper mold 113, wherein the middle mold 112 is connected to the lower mold 111 to form a molding cavity, and the lower mold 111 is mounted on the movable seat 120, and the upper mold 113 is mounted below the drive frame 130.

[0027] The movable seat 120 is used to drive the middle mold 112 and the lower mold 111 to move, and the movable seat 120 can move between the filling station and the molding station. When the movable seat 120 moves to the filling station, the first robot 200 and the second robot 300 can add the tile back 910 and powder to the molding cavity respectively. When the movable seat 120 moves to the molding station, the drive frame 130 can drive the upper mold 113 to move downward so that the tile back 910 and powder in the molding cavity form a brake shoe.

[0028] See Figure 1 as well as Figure 2 As shown, a guide groove is provided on the press body, and the movable seat 120 is slidably installed on the guide groove. The movable seat 120 has an integrated drive mechanism inside. The movable seat 120 can slide along the guide groove by the drive mechanism, thereby moving between the filling station and the molding station.

[0029] Because this application has a movable seat 120 that can be moved to the filling station, the lower mold 111 and the middle mold 112 can be moved out of direct view of the upper mold 113, thereby avoiding difficulties in adding materials due to obstruction by the upper mold 113. This reduces the difficulty of adding the backing tile 910 and powder.

[0030] As shown in the figure, the guide groove on the press body is set along the horizontal direction. In some implementations, the guide groove can also be set to extend obliquely downward, so that when the moving seat 120 is moved to the filling station, the moving seat 120 moves downward while moving horizontally, so that the upper operating space of the lower die 111 is larger.

[0031] It is understandable that the drive mechanism integrated inside the movable seat 120 can be a linear motor, a screw, or a cylinder, as long as it can drive the reciprocating linear motion of the movable seat 120.

[0032] See Figures 1 to 3 As shown, in some implementations, the powder adding system also includes a pouring mechanism 400, which is located on one side of the molding press 100. The pouring mechanism 400 includes a funnel 420, and the second robot 300 is used to add powder to the funnel 420. When the pouring mechanism 400 pours powder, the moving seat 120 moves to the filling station, and the outlet of the funnel 420 faces downward toward the top of the molding cavity. A valve 421 is also provided at the outlet of the funnel 420.

[0033] In other words, the funnel 420 in the dispensing mechanism 400 can guide the powder, ensuring it falls accurately into the corresponding area of ​​the molding cavity, thus preventing molding failure due to inaccurate powder dispensing when adding powder to the molding cavity. Because a valve 421 is installed at the outlet of the funnel 420, the powder can be temporarily stored in the funnel 420 before dispensing, preventing leakage. Furthermore, by controlling the continuous opening and closing of the valve 421 during the powder addition process, the powder in the hopper forms streams during the feeding process, creating a vibration-like effect and reducing the risk of powder residue remaining in the funnel 420.

[0034] See Figure 3 As shown, in some implementations, the material pouring mechanism 400 also includes a guide rail, on which a drive unit 430 is mounted. The drive unit 430 can move along the guide rail and is connected to the funnel 420 to move the funnel 420 to or above the filling station or out of the filling station. The drive unit 430 can also drive the funnel 420 to rotate and sway.

[0035] The position of the funnel 420 can be adjusted by moving the drive unit 430 on the guide rail, facilitating the addition of powder to the funnel 420 by the second robot 300. Specifically, the dispensing mechanism 400 includes a horizontal guide rail 411 and a vertical guide rail 412. The drive unit 430 is mounted on the horizontal guide rail 411 and can move horizontally along it. The horizontal guide rail 411 is mounted on the vertical guide rail 412, and the drive unit on the horizontal guide rail 411 can drive the horizontal guide rail 411 to move vertically on the vertical guide rail 412, thereby realizing the vertical movement of the funnel 420. In other words, the movement of the funnel 420 can be achieved using the horizontal guide rail 411 and the vertical guide rail 412, expanding the working space of the funnel 420.

[0036] Because the drive unit 430 can also drive the funnel 420 to rotate and shake, when adding to the molding cavity through the guide rail, the drive unit 430 can drive the funnel 420 to rotate, so that the powder remaining on the inner side of the funnel 420 can slide down out of the funnel 420, reducing the amount of powder remaining on the funnel 420.

[0037] The drive unit 430 can be a slider mounted on the transverse guide rail 411, and a rotary motor is provided on the drive unit 430. The rotary motor is connected to the funnel 420 through the rotating shaft, so that the drive unit 430 drives the funnel 420 to rotate and sway.

[0038] In some implementations, a dustproof bag is also installed below the funnel 420. By covering the outlet of the funnel 420 with a dustproof bag, dust can be reduced during the descent of the powder in the funnel 420, thus reducing powder contamination during the falling process.

[0039] See Figure 1 as well as Figure 4 As shown, in some implementations, the second robot 300 includes a first gripper 310 for gripping a material box 507 located at a first storage position, wherein the amount of powder in the material box 507 is equal to the amount of powder required for one brake shoe.

[0040] In other words, the amount of powder added to the material box 507 can be controlled to be the amount of powder required for the brake shoe, so as to achieve accurate control of the powder amount.

[0041] See Figure 1 , Figure 5 as well as Figure 6As shown, the second robot 300 has two first grippers 310, enabling it to simultaneously grasp two material boxes 507. Pairs of mold assemblies 110 are also provided on the forming press 100. The first grippers 310 grasp the material boxes 507 by gripping their side walls. A positioning hole structure is provided on the side of the material box 507 so that when the first grippers 310 grasp the material box 507, the positioning pin of the first gripper 310 first inserts into the hole structure on the side of the material box 507 to achieve clamping and positioning. This improves clamping accuracy and prevents the material box 507 from deviating from the first gripper 310, thus improving stability during the clamping process. The first grippers 310 employ a pneumatic gripper structure, and the cylinder stroke of the first gripper 310 should be greater than the maximum error in the width of the material box 507 to ensure that the first gripper 310 can effectively grasp the material box 507. Preferably, the cylinder stroke of the first gripper 310 is 50mm, which can accommodate the gripping of the material box 507 with a width variation within 50mm.

[0042] In some implementations, a material box 507 has two spaced-apart storage cavities, and the amount of powder in the two storage cavities is equal. Each material box 507 corresponds to two funnels 420. When the second robot 300 guides the powder from the material box 507 to the funnels 420, each storage cavity corresponds to one funnel 420. The two funnels 420 allow powder to be added to both sides of the nose of the valve during the process of adding powder to the molding cavity, preventing excessive powder from falling onto the nose. This ensures that after the valve is molded, the inner surface of the nose remains free of powder, facilitating the first robot 200 to pass through the inner surface of the nose and clamp it.

[0043] In other words, for the second robot 300 with two first grippers 310, the amount of powder it can grab at one time can simultaneously meet the production of two brake shoes. It requires two pairs, i.e., four funnels 420, to guide the powder in the four storage cavities of the two material boxes 507. Correspondingly, two sets of mold components 110 need to be set on the forming press 100 to realize the production of two brake shoes.

[0044] See Figure 5 as well as Figure 6 As shown, in some implementations, the first robot 200 is provided with a second gripper 210. The second gripper 210 includes a positioning part 211 and a clamping part 212. The positioning part 211 is used to insert into the tile nose positioning hole 911 of the tile back 910 for positioning. The clamping part 212 is used to insert into the tile nose insertion hole 912 of the tile back 910 after positioning to clamp the tile nose. The tile nose has at least two tile nose insertion holes 912.

[0045] In other words, by first inserting the positioning part 211 of the second gripper 210 into the positioning hole 911 of the nose of the formed brake shoe 900, and then extending the clamping part 212 into the nose insertion hole 912, and finally by moving the clamping part 212 relatively away from each other, the clamping part 212 is made to fit tightly against the hole wall of the nose insertion hole 912, thereby completing the external support clamping of the back of the shoe 910.

[0046] As mentioned above, in this application, by designing the material box 507 (with two non-connected storage cavities to store powder respectively) and setting two funnels 420 corresponding to one material box 507, the powder of a brake shoe is guided to different areas of the back 910, so that the nose of the back 910 is basically free of powder, avoiding the friction body 920 from adhering to the inner wall of the nose of the brake shoe after the brake shoe is formed, which would make it difficult for the second gripper 210 of the first robot 200 to grip the nose of the brake shoe.

[0047] In this application, a quick-connect connector 508 is provided on the first robot 200 to connect to the second gripper 210, thereby reducing the installation difficulty of the second gripper 210. Similarly, a quick-connect connector 508 is also provided on the second robot 300, and the second gripper 210 is connected through the quick-connect connector 508 provided on the second robot 300, thereby reducing the installation difficulty of the second gripper 210.

[0048] See Figure 1 As shown, in some implementations, the second robot 300 is also equipped with a cleaning mechanism 502. The cleaning mechanism 502 is used to clean the molding cavity before the first robot 200 places the tile back 910 into the molding cavity. The cleaning by the cleaning mechanism 502 prevents the outer surface of the tile back 910 (which is the side facing downwards into the molding cavity when the tile back 910 is placed) from adhering to the powder in the molding cavity, thus avoiding affecting the molding quality of the brake shoe. It is understood that the cleaning mechanism 502 can also be connected to the first robot 200, as long as its cleaning function is satisfied.

[0049] In other implementations, the cleaning mechanism 502 includes a reciprocating air blower and a reciprocating brush. The reciprocating air blower can blow away residual powder from the molding cavity, while the reciprocating brush can brush the powder away from the molding cavity. The powder carried by the brush can be shaken into the material box 507 for recycling.

[0050] Understandably, in some implementations, after adding powder to the inner side of the tile back 910, the powder that has fallen onto the tile nose can be pushed to the two sides of the tile back 910 of the tile nose by the cleaning mechanism 502 or the sorting barrier, so as to clean the powder on the tile nose and avoid the tile nose positioning hole 911 or tile nose insertion hole 912 being blocked due to too much powder adhering to the tile nose, making it difficult to use the second gripper 210 of the first robot 200 to hold the tile nose.

[0051] In some implementations, the mold assembly 110 is connected to a temperature control device, which is used to control the temperature inside the molding cavity at the molding temperature during extrusion molding by the molding press 100. That is, the molding temperature during the molding process can be adjusted by the temperature control device connected to the mold assembly 110 to ensure optimal molding results.

[0052] Specifically, heating pipes can be installed in the intermediate mold 112, and a temperature sensing device can be installed on the inner wall of the mold assembly 110. The temperature sensing device measures the temperature in the molding cavity and, referring to the optimal molding temperature at the current stage, adjusts the heating power of the heating pipes to ensure the best molding effect. The temperature control device can also include heat dissipation pipes installed in the intermediate mold 112. By controlling the temperature, flow rate, and velocity of the liquid in the heat dissipation pipes, a large amount of low-temperature liquid can be introduced into the heat dissipation pipes when a rapid reduction in the temperature inside the molding cavity is needed, increasing the cooling rate. When cooling is not required, the liquid in the heat dissipation pipes can be pumped out using a pump structure to prevent the heat dissipation liquid from lowering the temperature inside the molding cavity.

[0053] In some implementations, to facilitate the installation and connection of the upper, middle, and lower molds 111, corresponding guide structures can be provided on the top of the upper mold 113, the upper and lower ends of the middle mold 112, and the top of the upper mold 113. This reduces the installation difficulty between the upper, middle, and lower molds 111 and improves the positioning accuracy among them. The positioning structure can be a guide cone and a corresponding tapered guide hole. It can also be a wedge-shaped positioning structure or other shaped positioning structures.

[0054] See Figure 1 As shown, in some implementations, a finished product storage station is also provided on one side of the forming press 100, and the first robot 200 is also used to grab the qualified brake shoes to the finished product storage station after the brake shoes are qualified in the inspection station.

[0055] In the diagram, the finished product storage station is located on top of the AGV trolley 506, so that after the finished product storage station is full of brake shoes, the AGV trolley 506 can use its automatic transport function to transport the qualified brake shoes to the next production assembly station.

[0056] It is understandable that a waste storage station is also set up on the other side of the forming press 100. When the vision inspection device 501 detects that the brake shoe at the inspection station has a production defect, the first robot 200 can be used to transfer the brake shoe with the production defect to the waste storage station.

[0057] In some implementations, both the first robot 200 and the second robot 300 are six-axis robots. Compared to other robots, six-axis robots are more flexible and more mature. They can accurately add and transport materials.

[0058] See Figure 1 As shown, a gantry frame 503 is provided on one side of the forming press 100. Both the first robot 200 and the second robot 300 are mounted on the gantry frame 503, and are located on opposite sides of the forming press 100. The vision inspection device 501 is a vision inspection camera mounted on the inspection platform. It identifies whether the brake shoes have corresponding production defects by capturing images of the brake shoes at the inspection station. The inspection platform is located on the side closer to the first robot 200. Near the inspection platform, a brake shoe back 910 tray 504 is provided, on which brake shoe backs 910 without the friction body 920 attached are placed. On the side of the brake shoe back 910 tray 504 closest to the first robot 200 is the AGV trolley 506 at the finished product storage station, which is equipped with a tray 504 to store the inspected and qualified brake shoes. On the side of the 910 tray 504 near the second robot 300, there is a material box 507 storage station. An AGV trolley 506 is also set up at the material box 507 storage station, on which material boxes 507 filled with powder are placed. The second robot 300 completes the powder addition by sequentially picking up and placing each material box 507 at the material box 507 storage station.

[0059] Although the invention has been described with reference to preferred embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the invention.
