Description

Technical Field

[0001] The invention relates to the technical field of brake pad processing, in particular to a steel back automatic stamping die for processing automobile brake pads. Background Art

[0002] Automobile brake pads refer to the friction materials fixed on the brake drum or brake disc that rotates with the wheel. Automobile brake pads are mainly composed of brake pad steel back and friction materials through heat bonding technology. They are used in the braking system of the car. During the production process of brake pads, holes and grooves need to be opened on the steel back for the installation of screws and bolts.

[0003] In the steel back stamping device in the prior art, the positioning and fixing of the steel back is mostly done manually. The person relies on the naked eye to check the position between the steel back and the stamping part and align the steel back with the stamping part. This operation method reduces the accuracy of the steel back stamping, and the steel back also shifts during the stamping process.

[0004] In order to solve the problems existing in the prior art, people have conducted long-term exploration and proposed various solutions. For example, the Chinese patent document discloses a stamping device for the production of automobile brake pad steel backs with a publication number of CN218517524U, which includes a support table, a first spring is fixedly connected to the left and right sides of the support table, and a movable block is fixedly connected to the other side of the first spring. The middle of the two movable blocks is movably connected to the lower template, and the bottom of the left and right sides of the lower template are fixedly connected with a bellows. The present invention has a good stamping effect of the device through the coordination of the movable block, the lower template, the bellows, the collecting tank, the limit column and the movable plate. The extension of the hydraulic telescopic rod can drive the upper template to move downward, and the upper template drives the pressure block to move downward. Through the contact between the pressure block and the plate, the upper template pushes the plate to move downward, and the lower template pushes the movable block to move toward the inside of the support table. The stamping effect of the device is good through the coordination of the movable block, the lower template, the bellows, the collecting tank, the limit column and the movable plate.

[0005] The above solution has solved the problems of the prior art to a certain extent, but there are still the following shortcomings: the above patent completes the loading and unloading of the plate by manual operation, which requires loading first, then stamping processing, and after processing, the finished product is taken out. The whole process is manually operated. Such an operation method takes a long time as a whole, and it is difficult to achieve continuous stamping and punching work, which will reduce the efficiency of the stamping device in drilling holes on the steel back.

[0035] like Figure 1-Figure 3 As shown, the stamping assembly includes a guide rod 102, a lower press frame 103, a clamping plate 105, a stamping column 106 and a buffer spring 107. Four guide rods 102 are evenly connected in the middle of the top of the workbench 1. The lower press frame 103 is slidably connected between the upper sides of the guide rods 102. The external power equipment is on the lower press frame 103 and is electrically connected to the controller 101. It can drive the lower press frame 103 to move upward and downward. The clamping plate 105 is slidably connected to the bottom of the lower press frame 103. The stamping columns 106 are symmetrically connected to the front and back of the lower press frame 103.

[0036] like Figure 1 , Figure 4 and Figure 5 As shown, the auxiliary components include a connecting plate 104, a slider 201, a limiting rod 202, a rotating rod 205 and a fixed rod 206. The right side of the top of the workbench 1 is connected to the connecting plate 104 by bolts. The right side of the connecting plate 104 is symmetrically slidably connected to the slider 201 front and back. The right side of the placement plate 1041 is also symmetrically slidably connected to the slider 201 front and back. The limiting rod 202 is connected between the two sliders 201 on the front side and between the two sliders 201 on the rear side. A fixed rod 206 is symmetrically welded to the left side of the bottom of the connecting plate 104 front and back. The fixing rod 206 and the limiting rod 202 are both used to limit the steel back 108 stacked on the placement plate 1041. The rotating rod 205 is rotatably connected to the side walls of the lower pressure frame 103 that are far away from each other. The lower end of the rotating rod 205 is rotatably connected to the pushing frame 203, and the rotating rod 205 is inclined.

[0037] like Figure 1 and Figure 6-Figure 9As shown, the connecting assembly includes a rotating frame 301, a torsion spring 302, an inclined rod 304, an inclined block 305, a blocking rod 306 and a return spring 307. The rotating frame 301 is rotatably connected to the middle part of the workbench 1. The torsion spring 302 is connected between the front and rear sides of the rotating frame 301 and the workbench 1. The left end of the rotating frame 301 is slidably connected to the front and rear ends of the positioning frame 303. The left side of the pushing frame 203 is symmetrically slidably connected to the inclined rod 304 front and back. The right wall of the inclined rod 304 is an inclined surface. The return spring 307 is connected between the inclined rod 304 and the inside of the pushing frame 203. The front and rear sides of the top of the rotating frame 301 are connected to the inclined blocks 305. The top surface of the inclined block 305 is an inclined surface. The inclined block 305 is in contact with the inclined rod 304. The position on the workbench 1 near the front and rear sides of the rotating frame 301 is connected to the blocking rod 306, and the blocking rod 306 resists the rotating frame 301.

[0038] When the brake pad steel back 108 is being stamped, an external power device is required on the top of the lower pressing frame 103. The power device is electrically connected to the controller 101, and the lower pressing frame 103 is driven by the power device to move downward and upward. First, the limiting rod 202 is pushed outward to drive the slider 201 to move outward, and the steel back 108 is stacked on the placement plate 1041. The steel back 108 will be supported by the supporting rod 204, and then the limiting rod 202 is moved inward to reset, driving the slider 201 to move and reset. The fixed rod 206 limits the left side of the steel back 108, and the limiting rod 202 limits the right side of the steel back 108. Then, a piece of steel back 108 is placed separately in the middle of the workbench 1, and the positioning frame 303 limits the steel back 108 so that the steel back 108 is located on the lower pressing frame 1 03, and then the controller 101 can be operated to start the power equipment, which controls the power equipment to drive the lower pressure frame 103 to move downward along the guide rod 102, and the lower pressure frame 103 will drive the pressing plate 105 and the punching column 106 to move downward. The downward movement of the lower pressure frame 103 will drive the rotating rod 205 to rotate, so that the rotating rod 205 pushes the pusher frame 203 and the supporting rod 204 to move to the right. The steel back 108 on the supporting rod 204 is limited by the fixing rod 206 and the limiting rod 202, and will not move. The movement of the pusher frame 203 to the right will drive the inclined rod 304 to move to the right. When the inclined surface of the inclined rod 304 contacts the inclined block 305, the inclined block 305 will squeeze the inclined rod 304 to move inward, and the reset spring 307 is compressed. After that, the inclined rod 304 will move outward and reset under the reset action of the reset spring 307. After the support rod 204 moves to the right and no longer supports the stacked steel back 108, the steel back 108 will fall downward on the placement plate 1041 due to gravity. When the pressing plate 105 moves down to contact the steel back 108 on the workbench 1, the pressing plate 105 stops moving, and the lower pressing frame 103 continues to move down with the punching column 106. The buffer spring 107 is compressed, and the punching column 106 punches and drills the steel back 108. The waste generated will fall onto the discharge chute 109 and slide down through the discharge chute 109. A collection frame can be placed under the discharge chute 109 to collect the waste. When the lower pressing frame 103 moves down to the limit and the steel back 108 is also punched, the power equipment will automatically The lower pressure frame 103 is driven to move up and reset along the guide rod 102, thereby driving the stamping column 106 to move up, the buffer spring 107 is reset, and the pressing plate 105 is driven to move up and reset. After the reset, the power equipment will automatically pause. When the lower pressure frame 103 moves up and resets, it will drive the rotating rod 205 to reverse, so that the rotating rod 205 drives the pushing frame 203 and the supporting rod 204 to move to the left. The pushing frame 203 will push the bottom steel back 108 on the placement plate 1041 to move to the left, and the supporting rod 204 supports the other steel backs 108. The movement of the pushing frame 203 to the left also drives the inclined rod 304 to move to the left. When the inclined rod 304 contacts the inclined surface of the inclined block 305, the inclined rod 304 will push the inclined block 305 and the rotating frame 301 to rotate downward, and the torsion spring 302 will deform.The rotating frame 301 pulls the positioning frame 303 to move downward, so that the positioning frame 303 no longer limits the punched steel back 108 on the workbench 1, and the punched steel back 108 will be pushed out by the unpunched steel back 108. After the punched steel back 108 is pushed out, the inclined rod 304 is also separated from the inclined surface of the inclined block 305, and the rotating frame 301 is reversed and reset due to the reset of the torsion spring 302, thereby driving the inclined block 305 to reverse, and the rotating frame 301 will push the positioning frame 303 to move upward, so that the positioning frame 303 limits the unpunched steel back 108. The steel back 108 is prevented from moving too much due to the inertia of the pusher 203, and the accuracy of the loading position of the steel back 108 is ensured. The stopper 306 can limit the rotating frame 301 to prevent the rotating frame 301 from rotating too much. In this way, when the steel back 108 is automatically loaded, the accuracy of the loading position of the steel back 108 is ensured, and the stability of the steel back 108 during stamping is ensured. Repeat the above operation to continue the stamping work of the steel back 108. Finally, turn off the power after the work is finished.

[0039] Embodiment 2: Based on embodiment 1, Figure 6 and Figure 10-12 As shown, the stamping die also includes a limit plate 401, a compression spring 402, a pressure rod 403, a hinge rod 404 and a stop block 405. The middle part of the workbench 1 is symmetrically connected to the limit plate 401 for limiting the steel back 108 in a sliding manner. The left and right sides of the bottom of the limit plate 401 are connected to the inside of the workbench 1 with compression springs 402. The front and back sides of the bottom of the lower press frame 103 are symmetrically welded with pressure rods 403. The downward movement of the pressure rods 403 will move with the same The limit plate 401 on the side contacts and pushes the limit plate 401 to move downward. A stop block 405 is slidably connected to the position of the middle part of the workbench 1 near the push plate. A hinged rod 404 is symmetrically rotated front and back in the middle part of the workbench 1. The outer ends of the two hinged rods 404 are slidably connected to the limit plate 401 on the same side respectively, and the inner ends of the two hinged rods 404 are slidably connected to the stop block 405. The top surface of the stop block 405 is an inclined surface, which is used to correct the position of the steel back 108.

[0040] When the lower pressing frame 103 drives the punching column 106 to move downward to punch the steel back 108, the pressing rod 403 moves downward with the lower pressing frame 103. When the pressing rod 403 contacts the limit plate 401, it will push the limit plate 401 to move downward, the compression spring 402 is compressed, and the limit plate 401 will push the hinge rod 404 to rotate, so that the hinge rod 404 pushes the stop block 405 to move upward. The top surface of the stop block 405 is an inclined surface, and the stop block 405 can correct the position of the steel back 108 on the workbench 1. The stop block 405 moves upward and contacts the right side wall of the steel back 108. After the steel back 108 is loaded, the lower pressing frame 103 moves downward to cause the push rack 203 to move and reset. When the push rack 203 moves and resets and is out of contact with the steel back 108, the steel back 108 may Due to the slight offset caused by inertia, the stop block 405 can correct the position of the steel back 108. At the same time, the positioning frame 303 presses against the left side of the steel back 108, and the stop block 405 blocks the right side of the steel back 108. This can ensure the stability of the steel back 108 during the stamping process. After the stamping is completed, the lower pressing frame 103 drives the stamping column 106 to move up and reset, and then drives the pressure rod 403 to move up. The pressure rod 403 no longer contacts the limit plate 401. The limit plate 401 will move upward and reset under the reset action of the compression spring 402, and then drive the hinge rod 404 to reverse and reset. The hinge rod 404 drives the stop block 405 to move downward and reset. After the limit plate 401 moves up and resets, it can limit and guide the steel back 108 loaded onto the workbench 1.

[0041] like Figure 1 and Fig.13 As shown, the stamping die also includes a dual-axis motor 501 and a screw 502. The dual-axis motor 501 is installed on the right side of the connecting plate 104 by bolts. The two output shafts of the dual-axis motor 501 are connected to the screw 502. The screw 502 is rotatably connected to the connecting plate 104, and the two screws 502 are respectively threadedly connected to the two sliders 201 on the upper side.

[0042] When placing the steel back 108 on the placement plate 1041, the controller 101 can be operated to start the dual-axis motor 501. The output shaft of the dual-axis motor 501 rotates to drive the screw 502 to rotate. The screw 502 drives the upper slider 201 to move outward, and then drives the limit rod 202 and the lower slider 201 to move outward, so that the steel back 108 can be placed. After placement, the dual-axis motor 501 is controlled to operate in the reverse direction, which can drive the screw 502 to reverse, drive the slider 201 and the limit rod 202 to move inward and reset, and the limit rod 202 limits the steel back 108.

[0043] like Figure 1 and Figure 2As shown, the stamping die also includes a conveying component 6, which is installed on the left side of the top of the workbench 1. The conveying component 6 is electrically connected to the controller 101. The conveying component 6 is a prior art. After the conveying component 6 is started, the stamped steel back 108 is pushed to the left by the pushing rack 203 and moved to the belt on the conveying component 6, and will be transported and collected through the belt.
