Technical Field

[0001] The utility model relates to the field of automobile brake pad processing, in particular to an automatic positioning stamping die for a steel back plate used in the production of brake pads. Background Art

[0002] Brake pad steel backing plate, also known as steel backing, is an important part of brake pads. Its main function is to fix the friction material and facilitate the installation of brake pads on the braking system. The steel backing plate is usually made of high-strength, wear-resistant materials, such as Q235B carbon structural steel, to ensure that it can withstand the huge pressure and friction during braking.

[0003] In order to increase the bonding strength with the adhesive layer, the surface of the steel back plate of the current brake pad is usually punched and punctured, thereby increasing the bonding strength between the steel back plate and the adhesive layer. In order to facilitate the stamping of the steel back plate, an automatic positioning stamping die for the steel back plate of the brake pad production is required.

[0004] Currently, the steel back plate is generally punched and burred by placing a mold that matches the shape and size of the steel back plate on it, and then punching and burring the steel back plate. However, in actual use, the inclination angles on both sides of different types of steel back plates are different, which results in a set of steel back plate molds being suitable for only one type of steel back plate. When you want to change the processing model, you need to replace the steel back plate mold, and the equipment cost is relatively high. Therefore, an automatic positioning stamping mold for steel back plates for brake pad production is proposed to solve the above problems. Utility Model Content

[0032] Reference Figure 1-Figure 3 The top of the placement plate 4 is fixedly connected with a rotating bracket 7, and a threaded rod 8 is rotatably connected inside the rotating bracket 7. A round handle with a notch is provided at the right end of the threaded rod 8 to facilitate the rotation of the threaded rod 8. A threaded block 9 is threadedly connected to the outer periphery of the threaded rod 8. The rotation of the threaded rod 8 can drive the threaded block 9 to move left and right along the surface of the threaded rod 8. The top of the threaded block 9 is hinged with a support assembly, and the support assembly includes an articulated arm 10. The bottom end of the articulated arm 10 is hinged at the top of the threaded block 9. The articulated arm 10 is provided with two groups, which are symmetrically arranged on the front and rear sides of the articulated arm 10. The articulated arm 10 A sliding cylinder 11 is fixedly connected inside, a clamping arm 12 is hinged on the top of the placement plate 4, a rounded slide groove 13 is provided on the top of the clamping arm 12, the outer periphery of the sliding cylinder 11 is slidably connected inside the rounded slide groove 13, the rounded slide groove 13 limits the sliding cylinder 11 to slide left and right only along the inner wall of the rounded slide groove 13, a fixed bracket 14 is fixedly connected to the top of the base plate 1, a stop block 15 is fixedly connected to the top of the fixed bracket 14, two groups of stop blocks 15 are arranged, which are symmetrically arranged on the front and rear sides of the fixed bracket 14, the stop blocks 15 will press against the steel back plate to prevent the steel back plate from moving.

[0033] Reference Figure 1-Figure 3The top of the substrate 1 is fixedly connected to a stamping bracket 16, and the bottom of the stamping bracket 16 is provided with a stamping assembly for stamping and stabbing. The stamping assembly includes a stamping cylinder 17 that provides stamping power. The top of the stamping cylinder 17 is arranged on the inner wall of the top of the stamping bracket 16, and the telescopic end of the bottom of the stamping cylinder 17 is fixedly connected to a stamping upper die 18. When the stamping cylinder 17 is turned on, it will drive the stamping upper die 18 to move downward quickly to stamp the steel back plate. A plurality of groups of grooves are arranged at the bottom of the stamping upper die 18, and the top surface of the steel back plate can be stamped and stabbed. The front and rear sides of the stamping assembly are fixedly connected to connecting arms 19, and the connecting arms 19 are provided with two groups. The inner sides of the two groups of connecting arms 19 are respectively fixedly connected to the front and rear sides of the stamping upper die 18, and the outer sides of the connecting arms 19 are fixedly connected to the front and rear sides of the stamping upper die 18. A sliding seat 20 is fixedly connected, and the inner wall at the top end of the sliding seat 20 is elastically connected to a connecting rod 22 through a limit spring 21. When the connecting rod 22 is not subjected to force, the limit spring 21 will push the connecting rod 22 to move downward. One end of the limit spring 21 is fixedly connected to the inner wall at the top end of the sliding seat 20, and the other end of the limit spring 21 is fixedly connected to the top end of the connecting rod 22. The outer periphery of the connecting rod 22 is slidably connected to the inside of the sliding seat 20.

A pressure block 23 is fixedly connected to the bottom end of the connecting rod 22, and a rubber strip 24 is fixedly connected to the bottom end of the pressure block 23. The rubber strip 24 has a certain deformation ability, which reduces the impact force when the pressure block 23 contacts the steel back plate.

[0034] Working principle: when you want to conveniently adjust the mold to adapt to various types of steel back plates, rotate the threaded rod 8. The rotation of the threaded rod 8 drives the threaded block 9 to move to the right, and the threaded block 9 drives the right end of the articulated arm 10 to move to the right, and the left end of the articulated arm 10 drives the sliding cylinder 11 to move to the right, and at the same time drives the clamping arm 12 to rotate, so that the inclination of the clamping arms 12 on the front and rear sides changes. When the inclination is the same as the inclination of the steel back plate, turn on the electric push rod 2, and the output shaft at the left end of the electric push rod 2 drives the push plate 3 to move to the left, and the push plate 3 drives the placement plate 4 to move to the left, and at the same time drives the steel back plate to move to the left. When the steel back plate contacts the stop block 15, the steel back plate does not move, and at the same time the front and rear sides contact the clamping arm 12, tighten along the inclined surface, and complete the positioning of the steel back plate, which is below the stamping upper die 18, so that the mold can be easily adapted to various models. When stamping is in progress, the telescopic end at the bottom of the stamping cylinder 17 drives the stamping upper die 18 to move downward, and the stamping upper die 18 drives the pressing block 23 to move downward through the connecting arm 19. When the rubber strip 24 contacts the steel back plate, the connecting rod 22 moves upward to squeeze the limit spring 21. At the same time, the limit spring 21 will give the pressing block 23 a downward force, so that the steel back plate remains stable during stamping and will not vibrate.
