Description

Technical Field

[0001] This utility model relates to the field of hot press technology, specifically a hot press for processing sheet metal with a shock-absorbing structure. Background Technology

[0002] In the process of processing boards, hot pressing is a key step in the production process. By using the hot pressing plate on the hot press machine to process the boards, the environmentally friendly glue applied to the surface of the boards can be fully penetrated and the strength of the boards can be enhanced. Alternatively, a film can be laid on the boards to stably attach the film to the boards.

[0003] In existing hot presses, the sheet material is placed on the lower hot press plate, and the upper hot press plate is lowered to fix the sheet material between the lower and upper hot press plates. However, during the descent of the upper hot press plate, it will directly and rigidly contact the sheet material on the lower hot press plate, which will generate a large impact and produce a certain amount of vibration. At the same time, when the sheet material is placed on the lower hot press plate, it is impossible to control the sheet material to be centered between the lower and upper hot press plates, which may cause the sheet material to shift. The position of the sheet material needs to be manually adjusted, which is a rather cumbersome operation. Utility Model Content

[0004] The purpose of this invention is to provide a hot press for processing sheet metal with a shock-absorbing structure, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a hot press for processing sheet metal with a shock-absorbing structure, comprising a hot press body, a lower hot press plate fixedly installed on the upper surface of the bottom end of the hot press body, hydraulic rods symmetrically fixedly installed on the top of the hot press body, mounting plates fixedly installed on the moving ends of several hydraulic rods, an upper hot press plate movably installed below the mounting plates, and positioning blocks symmetrically installed on both sides of the hot press body corresponding to the hydraulic rods in the middle, the two positioning blocks being able to clamp and center the sheet metal.

[0006] As a further preferred embodiment of this technical solution, the mounting plate has symmetrically provided limit holes in the middle, and the top of the upper hot press plate is fixedly installed with a limit rod at the position corresponding to the limit hole. The limit hole and the limit rod are slidably connected, and a buffer spring is sleeved on the outer side of the top of the limit rod. One end of the buffer spring is fixedly connected to the top of the limit rod, and the other end of the buffer spring is fixedly connected to the upper surface of the mounting plate.

[0007] As a further preferred embodiment of this technical solution, positioning rods are symmetrically fixedly installed at the middle of the hot press body corresponding to the two sides of the lower hot press plate. The positioning block is slidably installed between the two positioning rods. A first inclined surface is opened on one side of the top of the positioning block. Extrusion blocks are fixedly installed at the middle of both sides of the upper hot press plate. A second inclined surface is opened on one side of the bottom of the extrusion block. The second inclined surface is in extrusion contact with the first inclined surface.

[0008] As a further preferred embodiment of this technical solution, a first return spring is sleeved on the outer side of one end of the positioning rod, one end of the first return spring is fixedly connected to one side of the positioning block, and the other end of the first return spring is fixedly connected to the hot press body.

[0009] As a further preferred embodiment of this technical solution, the side of the two positioning blocks that are close to each other is lower than the thickness of the plate.

[0012] This utility model provides a hot press for processing sheet metal with a shock-absorbing structure, which has the following beneficial effects:

[0013] (1) This utility model places the plate on the lower hot press plate and drives the mounting plate to descend through the hydraulic rod, which in turn drives the upper hot press plate to descend synchronously. When the upper hot press plate descends, the second inclined surface on the extrusion block on both sides of the upper hot press plate will extrude the first inclined surface on the top side of the positioning block. As the upper hot press plate descends, the positioning block will slide along the trajectory of the positioning rod. The side of the two positioning blocks that are close to each other will extrude the plate, which is used to control the plate to be placed in the center.

[0014] (2) When the mounting plate descends, the upper hot plate will first squeeze the plate. The impact force of the upper hot plate squeezing the plate will be buffered by the buffer spring to reduce the vibration. Then the mounting plate will continue to descend, which will drive the limit rod to slide inside the limit hole until the mounting plate and the upper hot plate are squeezed and contacted. The pressure of the hydraulic rod descending will be transmitted to the upper hot plate through the mounting plate to ensure the high pressure environment between the upper and lower hot plates. The heat transfer between the upper and lower hot plates is used for the hot pressing operation of the plate. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figures 1 to 5 As shown in this embodiment, a hot press for processing sheet metal with a shock-absorbing structure includes a hot press body 1. A lower hot press plate 20 is fixedly installed on the upper surface of the bottom end of the hot press body 1. Hydraulic rods 2 are symmetrically fixedly installed on the top of the hot press body 1. Mounting plates 3 are fixedly installed on the moving ends of several hydraulic rods 2. An upper hot press plate 4 is movably installed below the mounting plates 3. Positioning blocks 5 are symmetrically installed in the middle of the hot press body 1 at the positions on both sides of the hydraulic rods 2. The two positioning blocks 5 can clamp and center the sheet metal, placing it on the lower hot press plate 20, and then pressing it with hydraulic pressure. The rod 2 drives the mounting plate 3 to descend, which in turn drives the upper hot press plate 4 to descend synchronously. As the upper hot press plate 4 descends, it controls the two positioning blocks 5 to move towards each other. The side of the two positioning blocks 5 that is close to each other will squeeze the plate, which is used to control the plate to be placed in the center. Then, the mounting plate 3 continues to descend, which will drive the limit rod 7 to slide inside the limit hole 6 until the mounting plate 3 and the upper hot press plate 4 are pressed into contact. The pressure of the hydraulic rod 2 descending will be transmitted to the upper hot press plate 4 through the mounting plate 3 to ensure a high-pressure environment between the upper hot press plate 4 and the lower hot press plate 20. The heat transfer between the upper hot press plate 4 and the lower hot press plate 20 is used for the hot pressing operation of the plate.

[0023] like Figures 1 to 5 As shown, the mounting plate 3 has symmetrically opened limit holes 6 in the middle. The upper hot press plate 4 is fixedly installed with a limit rod 7 at the position corresponding to the limit hole 6. The limit hole 6 and the limit rod 7 are slidably connected. A buffer spring 8 is sleeved on the outer side of the top of the limit rod 7. One end of the buffer spring 8 is fixedly connected to the top of the limit rod 7, and the other end of the buffer spring 8 is fixedly connected to the upper surface of the mounting plate 3.

[0024] When the mounting plate 3 descends, the upper hot plate 4 will first squeeze the plate. The impact force of the upper hot plate 4 squeezing the plate is buffered by the buffer spring 8, reducing the impact of vibration.

[0025] like Figures 1 to 5 As shown, positioning rods 9 are symmetrically fixedly installed on both sides of the lower hot press plate 20 at the middle of the hot press body 1. The positioning block 5 is slidably installed between the two positioning rods 9. A first inclined surface 10 is opened on one side of the top of the positioning block 5. Extrusion blocks 11 are fixedly installed on the middle of both sides of the upper hot press plate 4. A second inclined surface 12 is opened on one side of the bottom end of the extrusion block 11. The second inclined surface 12 is in extrusion contact with the first inclined surface 10. A first return spring 13 is sleeved on the outer side of one end of the positioning rod 9. One end of the first return spring 13 is fixedly connected to one side of the positioning block 5, and the other end of the first return spring 13 is fixedly connected to the hot press body 1.

[0026] As the upper hot press plate 4 descends, the second inclined surface 12 on the extrusion blocks 11 on both sides of the upper hot press plate 4 will extrude the first inclined surface 10 on one side of the top of the positioning block 5. As the upper hot press plate 4 descends, it will drive the positioning block 5 to slide along the trajectory of the positioning rod 9. The side of the two positioning blocks 5 that are close to each other will extrude the plate material to control the plate material to be placed in the center. At this time, the first return spring 13 will be in the stretched state. After the hot pressing is completed, the upper hot press plate 4 is controlled to rise. The first return spring 13 pulls on the positioning block 5, which will drive the positioning block 5 to slide in the opposite direction along the trajectory of the positioning rod 9 to cancel the extrusion and positioning of the plate material by the two positioning blocks 5.

[0027] like Figures 1 to 5 As shown, the side of the two positioning blocks 5 that are close to each other is lower than the thickness of the plate.

[0028] The positioning block 5 is used to prevent the position of the plate from affecting the hot pressing process of the lower hot press plate 20 and the upper hot press plate 4 on the plate.

[0029] like Figures 1 to 5As shown, the upper hot press plate 4 has symmetrical sliding holes 14 in the middle. An extrusion rod 15 is slidably installed inside the sliding hole 14. A second return spring 16 is sleeved on the outer side of the top of the extrusion rod 15. One end of the second return spring 16 is fixedly connected to the top of the extrusion rod 15, and the other end of the second return spring 16 is fixedly connected to the upper surface of the upper hot press plate 4. A through hole 17 is opened on the mounting plate 3 at the position corresponding to the extrusion rod 15.

[0030] When the upper hot press plate 4 presses the plate, the reverse force of the plate on the pressing rod 15 will cause the pressing rod 15 to slide inside the sliding hole 14. At this time, the second return spring 16 is in the stretched state. After the hot pressing is completed, the mounting plate 3 is controlled to rise. The second return spring 16 pulls the top of the pressing rod 15, which will cause the pressing rod 15 to slide down inside the sliding hole 14. The bottom of the pressing rod 15 will press the plate, so that the plate is stuck to the upper hot press plate 4 due to the adhesive on the surface.

[0031] like Figures 1 to 5 As shown, the bottom of the upper hot press plate 4 is provided with an installation groove 18, and a rubber pad 19 is installed inside the installation groove 18.

[0032] When the upper hot press plate 4 is pressing the sheet material, the friction contact between the rubber pad 19 and the upper hot press plate 4 can be used to prevent the sheet material from sliding on the upper hot press plate 4 when the upper hot press plate 4 is pressing the sheet material.

[0033] This utility model provides a hot press for processing sheet metal with a shock-absorbing structure. The specific working principle is as follows:

[0034] When the device is in use, the plate is placed on the lower hot press plate 20. The mounting plate 3 is lowered by the hydraulic rod 2, which in turn lowers the upper hot press plate 4. When the upper hot press plate 4 is lowered, the second inclined surface 12 on the extrusion blocks 11 on both sides of the upper hot press plate 4 will extrude the first inclined surface 10 on one side of the top of the positioning block 5. As the upper hot press plate 4 is lowered, the positioning block 5 will slide along the trajectory of the positioning rod 9. The side of the two positioning blocks 5 that are close to each other will extrude the plate to control the plate to be placed in the center. At this time, the first return spring 13 will be in the extended state. After the hot pressing is completed, the upper hot press plate 4 is raised. The first return spring 13 pulls the positioning block 5 to cause the positioning block 5 to slide in the opposite direction along the trajectory of the positioning rod 9, which is used to cancel the extrusion and positioning of the plate by the two positioning blocks 5.

[0035] When the mounting plate 3 descends, the upper hot press plate 4 will first squeeze the plate. The impact force of the upper hot press plate 4 squeezing the plate is buffered by the buffer spring 8. Then, the mounting plate 3 is controlled to continue to descend, which will drive the limit rod 7 to slide inside the limit hole 6 until the mounting plate 3 and the upper hot press plate 4 are squeezed and contacted. The pressure of the hydraulic rod 2 descending will be transmitted to the upper hot press plate 4 through the mounting plate 3 to ensure the high pressure environment between the upper hot press plate 4 and the lower hot press plate 20. The heat transfer between the upper hot press plate 4 and the lower hot press plate 20 is used for the hot pressing operation of the plate.

[0036] When the upper hot press plate 4 presses the plate, the reverse force of the plate on the pressing rod 15 will cause the pressing rod 15 to slide inside the sliding hole 14. At this time, the second return spring 16 is in the stretched state. After the hot pressing is completed, the mounting plate 3 is controlled to rise. The second return spring 16 pulls the top of the pressing rod 15, which will cause the pressing rod 15 to slide down inside the sliding hole 14. The bottom of the pressing rod 15 will press the plate, so that the plate is stuck to the upper hot press plate 4 due to the adhesive on the surface.

[0037] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
