Description

Technical Field

[0001] The utility model relates to the technical field of steel back punching, in particular to a brake steel back edge pressing device. Background Art

[0002] The brake steel back refers to the supporting part of the brake pad, which is usually made of steel or iron. The function of the steel back is to support the brake pad to help the brake pad maintain a stable position. It can also improve the durability and performance of the brake pad. When the existing device performs edge pressing on the brake steel back, the steel back material is generally placed in the mold, and then it is stamped and formed by the stamping equipment. The formed steel back material is then manually removed. This process is relatively slow. In an industrial production environment, the speed of each operation link directly affects the overall production efficiency. Especially when the frequency of stamping is high, frequent manual material removal makes it difficult for operators to keep up with the rhythm of the stamping equipment, causing the equipment to have to wait intermittently for material removal, thereby reducing the output of steel back per unit time and affecting the production progress. To this end, we propose a brake steel back edge pressing device to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0023] Example: Figures 1-6As shown, the utility model provides a brake steel back pressing device, including a mold base 1, a mold groove 101 is opened on the top of the mold base 1, and a receiving frame 102 for placing multiple steel backs is fixedly connected to the mold base 1 around it. An assembly chamber 103 is opened at the bottom of the mold base 1, and a control component 2 for popping out the steel back is provided at the bottom of the inner cavity of the mold groove 101. The control component 2 includes two probe windows 201, and the two probe windows 201 are opened on both sides of the bottom of the inner cavity of the mold groove 101. The probe windows 201 on both sides are symmetrically distributed along the axis of the mold base 1, and a spring seat 202 is built in the probe window 201. The spring seat 202 does not contact the inner wall of the probe window 201 around it, and a connecting seat 203 is fixedly connected to the bottom of the spring seat 202. The end of the connecting seat 203 away from the spring seat 202 is fixedly connected to a rotating roller 204. The rotating roller 204 is placed in the assembly chamber 103, and the two ends of the rotating roller 204 are sleeved There is a fixed cylinder 205, which has a built-in torsion spring 206. The torsion spring 206 is sleeved on both ends of the rotating roller 204, and the torsion springs 206 at both ends are symmetrically distributed along the axis of the rotating roller 204. One end of the torsion spring 206 is fixedly connected to the inner wall of the fixed cylinder 205, and the other end of the torsion spring 206 is fixedly connected to the surface of the rotating roller 204. A connecting plate 207 is fixedly connected to the outer surface of the fixed cylinder 205, and the end of the connecting plate 207 away from the fixed cylinder 205 is fixedly connected to the inner wall of the assembly chamber 103. After the stamping process is completed, the computer system sends an instruction to control the extension of the telescopic cylinder 210, and the output end of the telescopic cylinder 210 pushes the push-pull plate 208 away from the connecting seat 203. At this time, the restrictive effect of the push-pull plate 208 on the connecting seat 203 disappears. After losing the restriction of the push-pull plate 208, the rotating roller 204 on the connecting seat 203 at the bottom of the spring seat 202 begins to rotate under the elastic force of the torsion spring 206. Because one end of torsion spring 206 is fixedly connected to the inner wall of fixed cylinder 205 and the other end is fixedly connected to the surface of rotating roller 204, and fixed cylinder 205 is fixed to the inner wall of assembly chamber 103 via connecting plate 207, the elastic force of torsion spring 206 is converted into rotational force for rotating roller 204. Rotating roller 204 drives connecting base 203 and spring base 202 upward, and spring base 202 suddenly pops out from protruding window 201. After spring base 202 pops out, it ejects the steel backing in mold cavity 101 into receiving frame 102. Receiving frame 102 is fixedly connected to mold base 1 on all sides and is used to hold multiple steel backings, facilitating their centralized collection.

[0024] Furthermore, a push-pull plate 208 is provided on one side of the two connecting seats 203. An elliptical surface 209 is provided on the side of the connecting seat 203 close to the push-pull plate 208 to facilitate contact with the transmission. One side of the push-pull plate 208 is slidably connected to the connecting seat 203. A telescopic cylinder 210 is provided on the side of the push-pull plate 208 close to the connecting seat 203. The output end of the telescopic cylinder 210 is fixedly connected to the push-pull plate 208. A fixed plate 211 is sleeved on the surface of the telescopic cylinder 210. The fixed plate 211 is fixedly connected to the telescopic cylinder 210. The end of the fixed plate 211 away from the telescopic cylinder 210 is connected to the assembly chamber. 103 inner wall. In the initial state of the device, the telescopic cylinder 210 is in a retracted state. Driven by the telescopic cylinder 210, the push-pull plate 208 is in close contact with the connecting seat 203. The connecting seat 203 is provided with an elliptical surface 209 on the side close to the push-pull plate 208 to facilitate contact transmission. The push-pull plate 208 is slidably connected to the elliptical surface 209, allowing the push-pull plate 208 to apply a stable force to the connecting seat 203. At this time, the spring seat 202 is located in the protruding window 201, and the connecting seat 203 at its bottom is connected to the structure in the assembly chamber 103 via the rotating roller 204. The rotating roller 204 has fixed cylinders 205 at both ends, and the torsion spring 206 in the fixed cylinder 205 is in a power storage state.

[0025] Working Principle: When the device is in use, in its initial state, the telescopic cylinder 210 is retracted. Driven by the telescopic cylinder 210, the push-pull plate 208 is in close contact with the connecting seat 203. An elliptical surface 209 is provided on the side of the connecting seat 203 near the push-pull plate 208 to facilitate contact transmission. The push-pull plate 208 is slidably connected to this elliptical surface 209, enabling the push-pull plate 208 to apply a stable force to the connecting seat 203. At this point, the spring seat 202 is located within the protrusion window 201, and the connecting seat 203 at its bottom is connected to the structure within the assembly chamber 103 via a rotating roller 204. The rotating roller 204 is sheathed with a fixed cylinder 205 at both ends, and the torsion spring 206 within the fixed cylinder 205 is in a charged state. Because of the restriction of the push-pull plate 208, the spring seat 202, while not in contact with the inner wall of the protrusion window 201, cannot be ejected. After the stamping process is complete, the computer system issues a command to extend the telescopic cylinder 210. The output end of the telescopic cylinder 210 pushes the push-pull plate 208 away from the connecting seat 203. At this point, the push-pull plate 208's restraining effect on the connecting seat 203 disappears. Without the restraint of the push-pull plate 208, the rotating roller 204 on the connecting seat 203 at the bottom of the spring seat 202 begins to rotate under the elastic force of the torsion spring 206. Because one end of the torsion spring 206 is fixedly connected to the inner wall of the fixed cylinder 205 and the other end is fixedly connected to the surface of the rotating roller 204, and the fixed cylinder 205 is fixed to the inner wall of the assembly chamber 103 via the connecting plate 207, the elastic force of the torsion spring 206 is converted into rotational force for the rotating roller 204. The rotating roller 204 drives the connecting seat 203 and the spring seat 202 upward, causing the spring seat 202 to suddenly eject from the projection window 201. Once ejected, the steel backing located in the die cavity 101 is ejected into the receiving frame 102. The receiving frame 102 is fixedly connected to the mold base 1 on all sides and is used to place multiple steel backs to facilitate the centralized collection of the steel backs.

[0026] The entire device's operation, from the activation of the telescopic cylinder 210 after stamping to the ejection of the steel backing from the ejector base 202, is computer-controlled. This automated control method reduces manual intervention and improves production accuracy and efficiency. Operators only need to perform simple setup and commissioning before starting the device, after which the device automatically operates according to the pre-set program. During the stamping process, there's no need for operators to constantly monitor the ejection of the steel backing, significantly reducing workload.

[0027] The coordination between the rotating roller 204 and the fixed cylinder 205 enables the torsion spring 206 to stably store and release energy, providing reliable power for the ejection of the cartridge 202. At the same time, the fixed cylinder 205 is fixed to the inner wall of the assembly chamber 103 via the connecting plate 207, ensuring the stability of the entire structure. The combination of the push-pull plate 208 and the telescopic cylinder 210 can effectively restrict the ejection of the cartridge 202 during the stamping process, ensuring the normal progress of the stamping process. After the stamping is completed, the restriction can be quickly released, allowing the cartridge 202 to eject smoothly. This design improves the reliability and safety of the device. Multiple steel backs can be stamped at one time and collected in the receiving frame 102, reducing the number of handling times and the number of times the equipment is started and stopped, further improving production efficiency.

[0028] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
