Description

Technical Field

[0001] The invention relates to the technical field of embossing and lettering, in particular to an embossing and lettering system. Background Art

[0002] At present, embossing is a process for forming text or patterns on the surface of materials. It mainly uses a certain pressure to make the text, pattern and other shapes on the mold or tool be embossed onto the target material. This pressure can change the shape of the material surface. For example, on metal materials, pressure can cause the metal to produce plastic deformation, thereby leaving the pattern or text permanently on the surface. On some softer materials such as leather and paper, embossing can also produce concave or convex marks on the surface through extrusion to show the required text or pattern; In the existing embossing process, since there is an angle between the engraving surface of the plate and the engraving mold before they come into contact, the plate bends due to pressure at the moment of contact between the plate and the mold, and the bent plate affects the contact with the mold, making it impossible to engrave. Summary of the invention

In the process of pressing down the pressing rod, the bottom end of the pressing rod is lower than the letter plate, so that it first contacts the plate, so that the pressing rod positions the plate, and at the same time, under the downward lettering pressure, the force between the pressing rod and the plate is transmitted to the spring, so that the spring contracts, and the pressing rod slides upward, so that the letter plate gradually contacts the plate. , embossing and engraving, using a pressure rod to press the plate to avoid deformation and bulges around the plate under pressure, causing damage to the plate. At the same time, the pressure rod restricts the plate before embossing and engraving, so that the plate is parallel to the letter plate, improving the embossing and engraving effect and avoiding lettering misalignment. The pressure rod is symmetrically installed along the center position of the axis of the top pad, and a threaded through hole is opened on the top of the top plate, and the threaded through holes of the top plate correspond to the pressure rods one by one. The threaded through holes of the top plate are all threadedly connected with screw blocks, and a spring is installed between the screw block and the pressure rod. The bottom end of the pressure rod is flush, and the bottom end of the pressure rod is lower than the bottom surface of the letter plate.

[0004] Preferably, a fixing frame is installed on the outer side of the top pad, the top of the fixing frame is fixedly connected to the bottom of the fixing plate, and the outer side of the fixing frame is tightly fitted with the outer side of the top pad, and a connecting plate is fixedly installed on the outer side of the fixing frame, and both ends of the outer side of the connecting plate are fixedly installed with an inclined surface block, and the inclined surface block cooperates with the inclined surface plate and the positioning plate. During the downward movement of the inclined surface block, the positioning plate and the inclined surface plate are driven to move inward through the inclined surface of the inclined surface block, and the plate is driven to adjust the position so that the center position of the plate corresponds to the center position of the letter plate, avoiding misalignment of the letter plate and the plate part, the bottom end of the opposite surface of the inclined surface block is an inclined surface, and it tilts outward from top to bottom, and the bottom of the fixing plate is fixedly connected with a limiting block, the limiting block is symmetrically installed along the center position of the axis of the connecting plate, and the limiting block is located at the corner of the outer side of the fixing frame.

[0005] Preferably, the supporting mechanism includes a supporting plate, which is fixedly installed at the center position of the top of the mold base, and a bottom pad is fixedly installed at the center position of the top of the supporting plate, and a top groove plate is fixedly installed on the top of the supporting plate, a plate groove is opened at the center position of the top of the top groove plate, and the edge of the plate groove is an inclined surface inclined inward from top to bottom, and a ejecting plate is slidably installed at the plate groove of the top groove plate, and the ejecting plate cooperates with the elastic pad to provide support for the insertion of the plate. When the center of the plate deviates excessively from the center position of the ejecting plate, the plate cannot be inserted, thereby avoiding excessive tilting of the inserted plate, which causes the positioning mechanism to be unable to adjust the plate and damages the plate when pressure is applied, and the outer side of the ejecting plate is an inclined surface inclined inward from top to bottom, and the inclined surface of the ejecting plate is adapted to the plate groove of the top groove plate.

[0006] Preferably, a sliding column is fixedly installed at the bottom of the top material plate, and the top material plate cooperates with the top groove plate. During the process of pressure engraving, the distance between the top material plate and the top groove plate before pressure is applied is used to cooperate with the positioning mechanism and the pressure plate mechanism to provide a buffer space for adjusting the position of the plate. At the same time, after the top material plate and the top groove plate are in contact, the top is flush to provide support for the bottom of the plate to ensure uniform force during engraving. The sliding column is symmetrically installed along the center position of the axis of the top material plate, and the bottom end of the sliding column passes through the top groove plate and extends to the inside of the support plate.

[0007] Preferably, the positioning mechanism includes a connecting block, which cooperates with the limiting block. During the downward movement of the pressing plate mechanism, the contact between the connecting block and the limiting block limits the downward movement of the pressing plate mechanism after the contact, so as to avoid that the downward movement range of the pressing plate mechanism is not limited, resulting in excessive pressure distance between the lettering plate and the plate, causing the plate to be subjected to greater pressure, and indentations appearing in areas outside the lettering area, resulting in a large number of indentations on the embossed lettering product, affecting the lettering quality.

[0008] The present invention provides an embossing and lettering system, which has the following beneficial effects: 1. The embossing and engraving system cooperates with the letter plate through the pressure rod. When the pressure rod is pressed down, the bottom end of the pressure rod is lower than the letter plate, so that it first contacts the plate, and the pressure rod positions the plate. At the same time, under the downward lettering pressure, the force between the pressure rod and the plate is transmitted to the spring, so that the spring contracts and the pressure rod slides upward, so that the letter plate gradually contacts the plate, and the lettering is embossed. The pressure rod is used to press the plate to avoid deformation and bulge around the plate under pressure, which causes damage to the plate. At the same time, the pressure rod restricts the plate before embossing and engraving, so that the plate is parallel to the letter plate, thereby improving the embossing and engraving effect and avoiding lettering dislocation.

[0009] 2. The embossing and lettering system cooperates with the inclined plate and the positioning plate through the inclined surface of the inclined surface block. When the inclined surface block moves downward, the inclined surface of the inclined surface block drives the positioning plate and the inclined plate to move inward, and drives the plate to adjust its position, so that the center position of the plate corresponds to the center position of the letter plate, thereby avoiding misalignment between the letter plate and the plate.

[0010] 3. The embossing and engraving system cooperates with the ejector plate and the elastic pad so that the ejector plate provides support for the placement of the plate. When the center of the plate deviates excessively from the center position of the ejector plate, the plate cannot be placed in, thereby preventing the placed plate from tilting excessively, causing the positioning mechanism to be unable to adjust the plate and damaging the plate when pressure is applied.

[0011] Fourth, the embossing and engraving system, through the cooperation of the top material plate and the top groove plate, uses the distance between the top material plate and the top groove plate before pressure is applied, cooperates with the positioning mechanism and the pressure plate mechanism, to provide a buffer space for the position adjustment of the plate. At the same time, after the top material plate and the top groove plate are fitted together, the top is flush to provide support for the bottom of the plate, ensuring uniform force during engraving.

[0012] 5. The embossing and engraving system cooperates with the connecting block and the limit block. During the downward movement of the pressure plate mechanism, the contact between the connecting block and the limit block limits the downward movement of the pressure plate mechanism after the contact, thereby avoiding that the downward movement range of the pressure plate mechanism is not restricted, resulting in excessive engraving pressure distance between the character plate and the plate, causing the plate to be subjected to greater pressure, and indentations in areas outside the engraving area, resulting in a large number of indentations in the finished embossed and engraved product, affecting the engraving quality.

A threaded through hole is opened on the top of the top plate 6, and the threaded through hole of the top plate 6 corresponds to the pressure rod 44 one by one. The bottom end of the pressure rod 44 is lower than the letter plate 7, and before the letter plate 7 contacts the plate, it first contacts the plate, and after the pressure rod 44 contacts the plate, the pressure rod 44 The bottom end is flush. When the plate is tilted, the raised end contacts the plate first, so that the pressure rod 44 contacts the raised end when the plate is tilted, and presses the tilted plate downward. In cooperation with the positioning mechanism 3, the spring 47 is gradually compressed during the downward pressing process, so that the pressure rod 44 slides upward, and the letter plate 7 gradually approaches the plate. The spring 47 is synchronously compressed to make the engraved surface of the plate parallel to the letter plate 7 before the letter plate 7 applies pressure to the plate. The threaded through holes of the top plate 6 are all threadedly connected with screw blocks 46, and a spring 47 is installed between the screw block 46 and the pressure rod 44. The bottom end of the pressure rod 44 is flush, and the bottom end of the pressure rod 44 is lower than the bottom surface of the letter plate 7.

[0017] A fixing frame 48 is installed on the outer side of the top pad 49, the top of the fixing frame 48 is fixedly connected to the bottom of the fixing plate 41, and the outer side of the fixing frame 48 is tightly fitted with the outer side of the top pad 49, and a connecting plate 42 is fixedly installed on the outer side of the fixing frame 48, and both ends of the outer side of the connecting plate 42 are fixedly installed with inclined blocks 45, the bottom end of the opposite surface of the inclined block 45 is an inclined surface, and it is inclined from top to bottom to the outside, and is fixedly connected to the top plate 6 through the fixing plate 41. Before assembly, the character plate 7 required for stamping is installed at the center position of the bottom of the top pad 49. During the stamping process, the inclined block 45 first contacts with the positioning mechanism 3. During the contact process, through the inclined surface at the bottom of the opposite surface of the inclined block 45, after the contact, the positioning mechanism 3 clamps the plate inwardly, and at the same time adjusts and positions the position of the plate. The bottom of the fixing plate 41 is fixedly connected to the limit block 43, and the limit block 43 is symmetrically installed along the center position of the axis of the connecting plate 42, and the limit block 43 is located at the corner of the outer side of the fixing frame 48.

[0018] The second embodiment is based on the first embodiment. Figures 7 and 8As shown, the support mechanism 2 includes a support plate 21, which is fixedly installed at the center position of the top of the mold base 1, and a bottom pad 22 is fixedly installed at the center position of the top of the support plate 21, and a top groove plate 23 is fixedly installed on the top of the support plate 21. A plate groove is opened at the center position of the top of the top groove plate 23, and the edge of the plate groove is an inclined surface inclined inward from top to bottom, and a top material plate 24 is slidably installed at the plate groove of the top groove plate 23. When the plate is placed, the plate is placed on the top of the top material plate 24, and the bottom of the plate is supported by the top material plate 24. At the same time, during the placement process, when the panel is excessively deviated from the center position of the ejector plate 24, the panel will not be able to be placed on the top of the ejector plate 24. When the pressure plate mechanism 4 and the positioning mechanism 3 adjust the panel, the pressure is transmitted to the slide column 25 through the ejector plate 24, so that the slide column 25 presses down the elastic pad 27, causing the elastic pad 27 to deform, and the ejector plate 24 can slide downward to provide a buffer space for the adjustment of the panel. The outer side of the ejector plate 24 is an inclined surface inclined inward from top to bottom, and the inclined surface of the ejector plate 24 is adapted to the plate groove of the top groove plate 23.

[0019] A slide column 25 is fixedly installed at the bottom of the ejector plate 24. The slide column 25 is symmetrically installed along the center position of the axis of the ejector plate 24, and the bottom end of the slide column 25 passes through the top groove plate 23 and extends to the inside of the support plate 21. A through groove is symmetrically opened at the bottom of the support plate 21. An elastic pad 27 is installed in the through groove of the support plate 21. The bottom of the elastic pad 27 is in contact with the top of the mold base 1. When the ejector plate 24 is completely in contact with the plate groove of the top groove plate 23, the ejector plate 24 is flush with the top of the top groove plate 23 to provide support for the plate. During the process of embossing the plate, the bottom is subjected to supporting force and is better embossed. The top of the elastic pad 27 is in contact with the bottom end of the slide column 25, and a positioning ring 26 is fixedly installed on the inner wall of the bottom pad 22. The inner wall of the positioning ring 26 fits tightly with the outer side of the slide column 25.

[0020] The third embodiment is based on the first and second embodiments. Figures 5 and 6As shown, the positioning mechanism 3 includes a connecting block 31, the bottom of which is fixedly connected to the top of the support plate 21, and the connecting block 31 is symmetrically installed along the center position of the axis of the support plate 21. The connecting block 31 is located directly below the limit block 43 and corresponds to the limit block 43 one by one. The outer side of the connecting block 31 is symmetrically provided with sliding holes. When the inclined surface block 45 moves downward, the inclined surface contacts the inclined surfaces of the positioning plate 33 and the inclined surface of the inclined plate 32. During the downward pressing process, the inclined surface block 45 contacts the inclined surfaces of the positioning plate 33 and the inclined surface of the inclined surface 32, and the positioning plate 33 and the inclined surface 32 drive the slider 34, so that the slider 34 compresses the elastic cushion sleeve 35, and the slider 34 slides on the inner wall of the connecting block 31 to move the inclined surface 32 and the positioning plate 33 inwardly, and the sliding holes of the connecting block 31 are slidably installed with the slider 34. 4, one end of one slider 34 close to the bottom pad 22 is fixedly connected to the inclined plate 32, and the other end of the slider 34 close to the bottom pad 22 is fixedly connected to the positioning plate 33, and an elastic cushion sleeve 35 is fixedly installed between the slider 34 and the connecting block 31. In the process of the inclined plate 32 and the positioning plate 33 moving inward, the position of the plate is adjusted. In the process of the inclined plates 32 and the positioning plates 33 approaching inward synchronously on all sides, the center position of the plate corresponds to the center position of the support mechanism 2. At the same time, through the one-to-one correspondence between the connecting block 31 and the limit block 43, the pressing distance is limited in the process of pressing down. The top of the outer side of the inclined plate 32 and the positioning plate 33 are both inclined surfaces inclined from top to bottom to the outside, and the top of the opposite surface of the positioning plate 33 is an inclined surface inclined from top to bottom to the outside.

[0021] When in use, the worker places the plate to be embossed and engraved into the center position of the top of the supporting mechanism 2, and at the same time makes the plate be on the inner side of the positioning mechanism 3. Then the worker inserts the top plate 6 through the positioning pin 5, so that the pressure plate mechanism 4 is at the top of the supporting mechanism 2 and the positioning mechanism 3, and at the same time makes the character plate 7 just above the plate to be embossed and engraved, completing the assembly of the embossing and engraving system. Then, the hydraulic equipment applies downward pressure on the top of the top plate 6, and the pressure plate mechanism 4 and the character plate 7 are driven downward by the top plate 6. During the movement, the pressure plate mechanism 4 cooperates with the positioning mechanism 3, and before the character plate 7 applies pressure to the plate, the plate is positioned and adjusted. At the same time, the pressure plate mechanism 4 cooperates with the supporting mechanism 2 to restrict the plate. Then, the pressure is transmitted to the plate through the character plate 7, and the plate is embossed and engraved.

[0022] In the pressing plate mechanism 4, the fixing plate 41 is fixedly connected with the top plate 6. Before assembly, the character plate 7 required for stamping is installed at the center position of the bottom of the top pad 49. During the stamping process, the inclined surface block 45 first contacts the positioning mechanism 3. During the contact process, the inclined surface of the bottom of the opposite surface of the inclined surface block 45 is used. After the contact, the positioning mechanism 3 clamps the plate inwards and adjusts the position of the plate at the same time. The pressing rod 44 cooperates with the bottom end of the pressing rod 44 to be lower than the character plate 7. Before the character plate 7 contacts the plate, , first contacts the plate, after the pressure rod 44 contacts the plate, due to the characteristic that the bottom end of the pressure rod 44 is flush, when the plate is tilted, the tilted end contacts the plate first, so that when the plate is tilted, the pressure rod 44 first contacts the tilted end, and presses the tilted plate downward, cooperates with the positioning mechanism 3, and gradually compresses the spring 47 during the downward pressing process, so that the pressure rod 44 slides upward, and the letter plate 7 gradually approaches the plate, and is synchronously compressed by the spring 47, so that the engraved surface of the plate is parallel to the letter plate 7 before the letter plate 7 presses the plate.

[0023] In the positioning mechanism 3, when the inclined surface block 45 moves downward, the inclined surface contacts the inclined surfaces of the positioning plate 33 and the inclined surface of the inclined panel 32. During the pressing process, the inclined surface block 45 contacts the inclined surfaces of the positioning plate 33 and the inclined surface of the inclined panel 32, and the slider 34 is driven by the positioning plate 33 and the inclined surface of the inclined panel 32, so that the slider 34 compresses the elastic cushion sleeve 35, and the slider 34 slides on the inner wall of the connecting block 31, so that the inclined surface of the inclined panel 32 and the positioning plate 33 move inward. During the inward movement of the inclined surface of the inclined panel 32 and the positioning plate 33, the position of the plate is adjusted. During the synchronous inward approach of the inclined surfaces 32 and the positioning plates 33 around the plate, the center position of the plate is made to correspond to the center position of the supporting mechanism 2. At the same time, through the one-to-one correspondence between the connecting block 31 and the limit block 43, the pressing distance is limited during the pressing process.

[0024] In the supporting mechanism 2, when the plate is put in, the plate is placed on the top of the ejector plate 24, and the bottom of the plate is supported by the ejector plate 24. At the same time, during the process of putting in, when the plate is excessively deviated from the center position of the ejector plate 24, the plate will not be able to be put on the top of the ejector plate 24. When the pressing plate mechanism 4 and the positioning mechanism 3 adjust the plate, the pressure is transmitted to the slide column 25 through the ejector plate 24, so that the slide column 25 presses down the elastic pad 27, causing the elastic pad 27 to deform, and the ejector plate 24 can slide downward to provide a buffer space for the adjustment of the plate. When the ejector plate 24 is completely in contact with the plate groove of the top groove plate 23, the ejector plate 24 is flush with the top of the top groove plate 23, providing support for the plate, so that during the process of embossing and engraving the plate, the bottom is supported and the embossing and engraving are better performed.
