Description

Technical Field

[0001] The utility model belongs to the technical field of equipment used for straightening, and particularly relates to a leveling mechanism for a silencer sheet. Background Art

[0002] Silencer pads are widely used in the brake systems of small cars and small and medium-sized trucks. Most of these products are made of a composite of high-polymer materials with silencer functions and metal sheets. They are installed on the back of the brake pads on the wheel calipers to reduce the noise generated by the friction between the brake pads and the wheel hub during braking.

[0003] In the Chinese patent with publication number CN219769085U, it is mentioned that the lower top wire can play a padding effect on the silencer sheet, and the upper top wire can play a pressing effect on the silencer sheet, so as to cooperate in leveling the silencer sheet when the upper and lower molds are closed; however, when producing semi-finished silencer sheets, the strip material will be cut into sheets, and then the molds are closed and punched. However, the cut sheet material will be warped at the edge of the cutting position due to the punching of the blade, affecting the subsequent semi-finished silencer sheet to smoothly pass through the gap between the upper and lower molds to complete leveling and positioning, which will cause the feeding of the semi-finished silencer sheet to be stuck, affecting the molding efficiency.

DETAILED DESCRIPTION

[0020] 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.

[0021] Reference Figure 1-Figure 4 As shown, the utility model provides a leveling mechanism for silencer sheets, including a frame 1, a guide mechanism 3 and a slitting mechanism 4. The frame 1 is a frame structure, which provides an overhead installation space. During manufacturing, the guide mechanism 3 is fixed in the middle of the frame 1, and the slitting mechanism 4 is arranged directly above the guide mechanism 3. When in use, the strip-shaped silencer sheet material is horizontally extended into the guide mechanism 3. At this time, the slitting mechanism 4 includes a cutter 42 that moves up and down. The cutter 42 can cooperate with the slitting mechanism 4 to cut the strip-shaped silencer sheet material into sheet-shaped silencer sheet material, so that the subsequent further punching and shaping can obtain silencer sheets of preset sizes. Among them, the blade position of the sheet-shaped silencer sheet material cut directly by the cutter 42 will undergo disordered deformation due to stamping, such as warping up and down. This warping will easily affect the subsequent positioning and punching in the mold. Therefore, after the slitting is completed, the frame 1 is provided with a flattening mechanism on one side of the cutter 42. The flattening mechanism 5 comprises a pressing plate 52 which moves up and down. At this time, the cut sheet of silencer sheet raw material will be pushed under the pressing plate 52. As the pressing plate 52 moves downward, the guide mechanism 3 and the pressing plate 52 will squeeze and straighten the sheet of silencer sheet raw material to obtain a semi-finished silencer sheet raw material with higher straightness and meeting the processing standards. In addition, the pressing plate 52 serving as a straightening part is provided with an inclined block 54 near one end of the cutter 42. When the cutter 42 moves downward for cutting, the pressing plate 52 will drive the inclined block 54 to move downward synchronously. In addition, the side wall of the bottom end of the inclined block 54 is set upward near one end of the cutter 42. The inclined block 54 can press the silencer sheet raw material just cut out to prevent the silencer sheet from bouncing out of the guide mechanism 3 at the moment of being cut, thereby ensuring that the silencer sheet raw material in the guide mechanism 3 is in a single-layer horizontal arrangement, and preventing the silencer sheets from being pressed down by the pressing plate 52 when they are stacked on each other, thereby avoiding affecting the thickness of the silencer sheet.

[0022] In a further embodiment, referring to Figure 2 The slitting mechanism 4 also includes a mounting base 41, which drives a vertically arranged hydraulic cylinder. The mounting base 41 drives the cutter 42 to move up and down. In addition, the mounting base 41 is assembled and connected to the frame 1 through the hydraulic cylinder, and is equipped with a graphite guide rod to ensure the vertical stability of the cutter 42 when moving up and down, thereby ensuring the accuracy of slitting.

[0023] In a further embodiment, referring to Figure 3An elastic pressure frame 43 is installed at the bottom of the mounting seat 41. The elastic pressure frame 43 includes a spring at the top and a flat plate at the bottom. When the mounting seat 41 moves downward, the spring can be extended and retracted up and down, and the flat plate contacts the strip-shaped silencer sheet material before the cutter 42. At this time, as the cutter 42 moves downward, the spring will be compressed and stored, so that when the strip-shaped silencer sheet material is cut by the cutter 42, the strip-shaped silencer sheet material is in a compressed state as a whole, and will not bounce up and down or move left and right significantly, ensuring that the position is stable during cutting. The cutter 42 is located between the elastic pressure frame 43 and the inclined block 54, which can prevent the elastic pressure frame 43 and the inclined block 54 from affecting each other, thereby ensuring the smooth implementation of the function.

[0024] In a further embodiment, referring to Figure 2 and Figure 3 The guide mechanism 3 includes a guide rail 32, which forms a concave material transfer channel. The guide rail 32 is provided with a cutting block 33 directly below the cutter 42. The cutting channel corresponds to the cutter 42 for carrying out the cutting. The top surface of the cutting block 33 is provided with a knife groove 35. When the cutter 42 is inserted into the knife groove 35 downward, the V-shaped knife groove 35 will support the sound-absorbing sheet material, so that the lower end of the cutter 42 can move downward smoothly, and the sound-absorbing sheet material can be completely cut off. The V-shaped knife groove 35 will not directly squeeze the cutting edge position at the bottom end of the cutter 42, thereby ensuring the long-term and stable use of the cutter 42.

[0025] In a further embodiment, referring to Figure 2 The guide mechanism 3 also includes a stand 31, which is installed at the right end of the guide rail 32 and belongs to the guide structure of the loading end. The stand 31 is provided with an opening at the concave part of the guide rail 32 corresponding to the guide rail 32. The strip-shaped silencer sheet raw material is passed through the opening to limit the raw material, ensuring that when a new silencer sheet is replaced, it can be smoothly inserted into the guide rail 32. The guide rail 32 is away from the stand 31. A lower hopper 34 is provided at the end, and a conveyor 2 is installed at the right end of the guide rail 32. The conveyor 2 transports the strip-shaped silencer sheet raw material to the left, and while performing continuous slitting, the cut sheet-shaped silencer sheet raw material is pushed to the left for stamping and straightening, and finally falls downward from the lower hopper 34 and separates from the guide rail 32 to obtain a flat sheet-shaped silencer sheet raw material.

[0026] In a further embodiment, referring to Figure 4The flattening mechanism 5 also includes a second mounting seat 51. A hydraulic cylinder is installed on the top of the second mounting seat 51 to provide up and down driving force. The second mounting seat 51 is assembled and connected to the pressure plate 52 by a threaded rod 57. The pressure plate 52 and the second mounting seat 51 are detachably fixed. While ensuring the downward pressure is stable, the pressure plate 52 can be replaced and the stamping stroke can be adjusted, so that it can adapt to silencers of different front and rear widths and thicknesses. It is practical to use. In addition, a slide groove 53 is provided on the end of the pressure plate 52 close to the cutter 42. The inclined block 54 is horizontally slidably installed in the slide groove 53. The inclined block 54 can slide left and right to adjust the distance between it and the cutter 42 to avoid direct contact with the cutter 42, and can adapt to the left and right widths of different silencers cut out. In addition, a lower inserting frame 58 is installed on the end of the pressure plate 52 away from the cutter 42. As the pressure plate 52 descends, the sheet-like silencer raw material located on the leftmost side is pressed down into the lower hopper 34 to ensure continuous slitting and straightening.

[0027] In a further embodiment, referring to Figure 4 The front and rear side walls of the inclined plane block 54 are installed with horizontal bars 55, and a flat groove is opened in the middle of the slide groove 53 to slide horizontally with the horizontal bar 55, which can ensure that the horizontal adjustment will not affect the horizontal position of the inclined plane block 54. At the same time, a top plate 56 is installed on the top of the inclined plane block 54, and a bolt is installed vertically through the edge of the top plate 56. The bottom end of the bolt is squeezed on the top surface of the pressure plate 52 to quickly fix the position of the inclined plane block 54. By loosening the bolt, the inclined plane block 54 can be freely slid left and right or the inclined plane block 54 can be removed and replaced, which is more flexible to use.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
