Description

Technical Field

[0001] This utility model relates to a multi-station stamping device for steel back processing, belonging to the technical field of stamping devices. Background Technology

[0002] Brake pads, also known as brake discs, are the most critical safety component in a car's braking system. The effectiveness of braking depends entirely on the brake pads. Brake pads use a steel backing, which is manufactured using a stamping device.

[0003] Chinese Patent Publication No. CN 216501768 U discloses a stamping device for processing the steel backing of automotive brake pads, including a base, a positioning device, and a stamping device. The positioning device includes a base frame, a protective frame, a motor, a large gear, a small gear, a movable groove, a double-acting screw, a guide rod, movable blocks, guide holes, a support plate, a mounting base, and a bottom mold. The top of the base is fixedly connected to the base frame, and one end of the base frame is fixedly connected to the protective frame. The top of the base frame has a movable groove, and the movable blocks are slidably connected inside the movable groove. This application starts the motor, which drives the large gear to rotate. The large gear drives the meshing small gear to rotate, and the small gear drives the double-acting screw to rotate. The double-acting screw is threadedly connected to two movable blocks, which slide along the movable groove under the action of the double-acting screw. Both movable blocks slide along the guide rod through the guide holes. The movable blocks drive the support plate to clamp and fix the mounting base, thereby facilitating the quick installation of the bottom mold and making it convenient for stamping.

[0004] The above-mentioned device does not have the function of unloading the stamped steel backing. After the steel backing is stamped, it may be stuck in the mold and difficult to remove. If the steel backing cannot be easily removed, it may affect the continuity of the stamping process of the steel backing, and thus affect the efficiency and speed of the overall stamping process of the steel backing, making it inconvenient for operators to use.

[0005] To address this, a multi-station stamping device for steel back processing is proposed. Utility Model Content

[0006] In view of this, the present invention provides a multi-station stamping device for steel back processing to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0007] The technical solution of this utility model is achieved as follows: A multi-station stamping device for steel back processing, comprising:

[0008] A stamping assembly includes a worktable, a support frame fixedly mounted on the top of the worktable, a hydraulic cylinder fixedly mounted on the top of the support frame, a lower pressure plate fixedly mounted on the bottom of the hydraulic cylinder, top dies fixedly mounted on the left and right sides of the bottom of the lower pressure plate, bottom dies fixedly mounted on the left and right sides of the top of the worktable, an mounting frame fixedly mounted on the bottom of the worktable, and a partition fixedly mounted on the inner side of the mounting frame.

[0009] The material feeding assembly includes a servo motor and bidirectional screws. The servo motor is fixedly mounted on the bottom of the mounting frame. Both bidirectional screws are movably connected to the inner side of the mounting frame. Screw blocks are threaded onto the left and right sides of the surfaces of the two bidirectional screws. Fixing rods are fixedly mounted on the tops of the four screw blocks. First trapezoidal blocks are fixedly mounted on the tops of the four fixing rods. Hard springs are fixedly connected to the left and right sides of the bottom of the worktable. Second trapezoidal blocks are fixedly connected to the other ends of the two hard springs. The bottoms of the two second trapezoidal blocks are attached to the tops of the four first trapezoidal blocks. Push rods are fixedly mounted on the tops of the two second trapezoidal blocks.

[0010] More preferably, the output end of the servo motor is fixedly connected to an active bevel gear, and the inner sides of the two bidirectional screws are fixedly connected to driven bevel gears, with the surfaces of the two driven bevel gears meshing with the surface of the active bevel gear.

[0011] More preferably, slots are provided on both the left and right sides of the top of the workbench, and the two push rods pass through the inner cavities of the two slots and extend into the inner cavities of the two bottom molds.

[0029] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0030] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0031] Example 1

[0032] like Figure 1-6 As shown, this utility model embodiment provides a multi-station stamping device for steel backing processing, comprising:

[0033] The stamping assembly 1 includes a worktable 101. A support frame 102 is fixedly installed on the top of the worktable 101. A hydraulic cylinder 103 is fixedly installed on the top of the support frame 102. A lower pressure plate 104 is fixedly installed on the bottom of the hydraulic cylinder 103. Top molds 105 are fixedly installed on the left and right sides of the bottom of the lower pressure plate 104. Bottom molds 106 are fixedly installed on the left and right sides of the top of the worktable 101. An mounting frame 107 is fixedly installed on the bottom of the worktable 101. A partition 108 is fixedly installed on the inner side of the mounting frame 107.

[0034] The material discharge assembly 2 includes a servo motor 201 and two bidirectional screws 204. The servo motor 201 is fixedly mounted on the bottom of the mounting bracket 107. Both bidirectional screws 204 are movably connected to the inner side of the mounting bracket 107. Screw blocks 205 are threaded onto the left and right sides of the surfaces of the two bidirectional screws 204. Fixing rods 206 are fixedly mounted on the tops of the four screw blocks 205. First trapezoidal blocks 207 are fixedly mounted on the tops of the four fixing rods 206. Hard springs 208 are fixedly connected to the left and right sides of the bottom of the worktable 101. Second trapezoidal blocks 209 are fixedly connected to the other ends of the two hard springs 208. The bottoms of the two second trapezoidal blocks 209 are attached to the tops of the four first trapezoidal blocks 207. Pushers are fixedly mounted on the tops of the two second trapezoidal blocks 209. The output end of the rod 210 and the servo motor 201 is fixedly connected to the active bevel gear 202. The inner sides of the two bidirectional screws 204 are fixedly connected to the driven bevel gears 203. The surfaces of the two driven bevel gears 203 mesh with the surfaces of the active bevel gears 202. The top left and right sides of the worktable 101 are provided with slots 211. The two push rods 210 pass through the inner cavities of the two slots 211 and extend into the inner cavities of the two bottom molds 106. The left and right sides of the surface of the partition 108 are provided with sliding grooves 212. The four fixed rods 206 pass through the inner cavities of the two sliding grooves 212 and extend into the top of the partition 108. The left and right sides of the surface of the mounting bracket 107 are provided with limit grooves 213. The bottoms of the four screw blocks 205 are slidably connected to the inner cavities of the two limit grooves 213.

[0035] By setting up the material discharge component 2, the output of the servo motor 201 causes the screw block 205 to drive the first trapezoidal block 207 to move inward. At this time, the first trapezoidal block 207 pushes the push rod 210 upward, which can push out the steel back stuck in the inner cavity of the bottom mold 106. This saves the step of the operator manually removing the material when the steel back is stuck in the inner cavity of the bottom mold 106, ensuring the continuity of the steel back stamping process, improving the efficiency of the steel back stamping, and facilitating the operator. In use, by setting slot 211, the movement of push rod 210 can be limited to prevent it from deviating during movement, thus affecting the discharge and ejection of steel backing. By setting slide groove 212, the movement of fixed rod 206 can be limited to prevent it from deviating during movement, thus affecting the discharge of steel backing. By setting limit groove 213, the movement of screw block 205 can be limited to prevent screw block 205 from rotating synchronously with active bevel gear 202.

[0036] Example 2

[0037] like Figure 1-2As shown, in one embodiment, guide rods 109 are fixedly installed on the left and right sides of the top of the workbench 101, and the left and right sides of the lower pressure plate 104 are slidably connected to the surfaces of the two guide rods 109. The left and right sides of the surfaces of the two bottom molds 106 are threaded with mounting bolts 110, and the bottom of the mounting bolts 110 is threaded to the inner surface of the workbench 101. The front and rear sides of the bottom of the workbench 101 are fixedly installed with base plates 111, and the surfaces of the two base plates 111 are threaded with anchor bolts 112.

[0038] By setting guide rod 109, the lower pressure plate 104 can be guided to avoid deviation in direction when it moves the top mold 105. By setting mounting bolt 110, the bottom mold 106 can be disassembled and assembled, preventing the bottom mold 106 from changing position when it moves the top mold 105 to press the steel back inside the bottom mold 106. By setting anchor bolt 112, the overall equipment can be stabilized to prevent the equipment from shaking due to accidental collisions caused by external factors.

[0039] In operation, this invention works as follows: First, the raw material for the steel backing is placed in the inner cavity of the bottom mold 106. Then, through the extension of the hydraulic cylinder 103, the lower pressure plate 104 drives the top mold 105 to move downward. Through the cooperation of the top mold 105 and the bottom mold 106, the stamping of the steel backing is completed. After stamping, the hydraulic cylinder 103 drives the lower pressure plate 104 and the top mold 105 to move upward. Then, the output end of the servo motor 201 drives the active bevel gear 202 to rotate. At this time, the driven bevel gear 203 cooperates with the active bevel gear 202, driving the driven bevel gear 203 to rotate. The driven bevel gear 203 drives the bidirectional screw 204 to rotate synchronously, thereby causing the screw block 205 to move inward. The screw block 205 drives the fixed rod 206 and the first trapezoidal block 20 7. Moving inward, as the first trapezoidal block 207 moves, it cooperates with the second trapezoidal block 209, causing the second trapezoidal block 209 to push the push rod 210 upward. At this time, the hard spring 208 is compressed and deformed. The push rod 210 pushes the steel back out of the inner cavity of the bottom mold 106, thus completing the material removal work. After the material removal is completed, the servo motor 201 outputs in the reverse direction, causing the bidirectional screw 204 to rotate in the reverse direction, driving the screw block 205, the fixing rod 206 and the first trapezoidal block 207 to move outward. At this time, the hard spring 208 loses the force and deforms. The hard spring 208 pushes the second trapezoidal block 209 downward, causing the push rod 210 to move downward synchronously. Then, the above steps are repeated to complete the continuous stamping and material discharge of the steel back.

[0040] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
