Description

Technical Field

[0001] This application relates to the field of sheet metal processing, and in particular to a heat-pressing buffer structure for preventing sheet metal deformation. Background Technology

[0002] A sheet metal hot press is a device based on the principle of high temperature and high pressure, specifically used for pressing sheet metal. First, the sheet metal is placed on the hot press plate, and then pressure is applied through the hydraulic system to make the sheet metal be pressed under uniform pressure. The electric heating system heats the hot press plate to the required high temperature to ensure that the sheet metal is fully fused under high temperature and high pressure. During the hot pressing of the sheet metal, a buffer structure is required to cushion the sheet metal to prevent damage due to excessive pressure.

[0003] However, during the implementation of the relevant technical solutions, at least the following technical problems were found: Springs are generally used to buffer the hot pressing plate when it presses down on the plate during the hot pressing process. However, the size and thickness of the plates are not the same during processing, and the height of the hot pressing plate also changes accordingly. The position of the buffer structure is generally fixed, which means that the buffer springs and the hot pressing plate may be damaged and deformed due to the excessive instantaneous pressure during pressing, affecting the completion rate of the hot pressing process. Utility Model Content

[0004] This application solves the problem in the prior art that springs and plates may deform due to downward pressure by providing a hot-pressing buffer structure to prevent deformation of the sheet metal, and achieves the effect of limiting the deformation of springs and sheet metal.

[0005] This application provides a hot-pressing buffer structure to prevent deformation of sheet metal, including movable seats on both sides of the top of a base, a hot-pressing assembly on the top of the base, a placement seat in the middle of the base, a buffer assembly for buffering hot press on the top of the movable seats, and a moving assembly at the bottom of the movable seats. The moving assembly includes: two lead screws rotatably connected to both sides of the base, with the movable seats sleeved and threadedly connected to the top of the lead screws; two insert rods on both sides of the bottom of the movable seats, each insert rod being inserted into and connected to the base; and a driving component inside the base, which drives the two lead screws to rotate synchronously.

[0006] Furthermore, the base has an internal cavity, and the driving component includes: two sprockets, which are respectively fixedly disposed at the bottom ends of the two lead screws that extend into the cavity, and the two sprockets are rotatably connected to the inside of the cavity; a chain, which is meshed with the outside of the two sprockets; and a reduction motor, which is fixedly installed at the bottom of the cavity, and the output shaft of the reduction motor is fixedly connected to one of the sprockets.

[0007] Furthermore, a scale plate is provided on the insertion rod.

[0008] Furthermore, the top of the movable seat is provided with a sliding groove, the bottom of the sliding groove is stepped, and the buffer assembly includes: a buffer seat, which is slidably connected to the inside of the sliding groove; a damper, which is disposed inside the sliding groove, and the top of the damper is fixedly connected to the buffer seat; and a spring, which is sleeved on the outside of the damper, and the two ends of the spring are fixedly connected to the buffer seat and the bottom of the sliding groove, respectively.

[0009] Furthermore, a positioning component is provided at the bottom of the movable seat. The positioning component includes: a threaded rod, which is threadedly connected to the bottom of the movable seat; and a positioning plate, which is slidably connected to the side of the movable seat near the placement seat.

[0011] The technical solution provided in this application has at least the following technical effects or advantages:

[0012] The spring and damper at the bottom of the buffer seat buffer the downward pressure of the hot press plate in the hot pressing assembly.

Detailed Implementation

[0018] This application discloses a hot-press buffer structure to prevent deformation of the sheet metal. The spring force of the spring 53 buffers the downward pressure of the hot-press plate. The rotation of the two lead screws 61 drives the two movable seats 40 to move up and down to a designated position, so that the downward pressure of the hot-press plate on the hot-press assembly 20 will not exceed the limit position of the buffer seat 51, thus preventing the sheet metal and spring 53 from being deformed and damaged due to excessive pressure.

[0019] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0020] Please refer to Figure 1 , Figure 2 and Figure 3 This embodiment provides a hot-pressing buffer structure to prevent deformation of sheet metal, including movable seats 40 on both sides of the top of a base 10, a hot-pressing assembly 20 on the top of the base 10, a placement seat 30 in the middle of the base 10, and a buffer assembly 50 for buffering hot pressing on the top of the movable seats 40. A groove 41 is formed on the top of the movable seats 40, and the bottom of the groove 41 is stepped. The buffer assembly 50 includes a buffer seat 51, a damper 52, and a spring 53. The buffer seat 51 is slidably connected to the inside of the groove 41. The cross-section of the groove 41 is stepped with a smaller bottom diameter and a larger top diameter. The buffer seat 51 is slidably connected to the position with the larger top diameter of the groove 41. The damper 52 is disposed inside the groove 41, and the top of the damper 52 is flush with the top of the groove 41. The buffer seat 51 is fixedly connected, and the spring 53 is sleeved on the outside of the damper 52. The two ends of the spring 53 are fixedly connected to the bottom of the buffer seat 51 and the slide groove 41, respectively. The hot press plate is driven to move down to the plate position for hot pressing by the hydraulic rod on the hot press assembly 20. The hot press plate first moves down to the position of contact with the top buffer seat 51 of the movable seat 40. The hot press plate drives the buffer seat 51 to move down, causing the damper 52 and the spring 53 to contract accordingly. The elastic force of the spring 53 buffers the downward movement of the hot press plate, preventing the plate from deforming due to excessive pressure when the hot press plate is pressed down. The stepped slide groove 41 prevents the buffer seat 51 from moving down to the stepped position and thus ensures that the spring 53 does not exceed the elastic limit and prevents the spring 53 from being damaged due to excessive pressure.

[0021] Please refer to Figures 1-4The movable base 40 has a moving component 60 at its bottom. The moving component 60 includes lead screws 61, a drive component, and insert rods 65. The two lead screws 61 are rotatably connected to both sides of the base 10, and the movable base 40 is sleeved and threadedly connected to the top of the lead screws 61. The two insert rods 65 are located on both sides of the bottom of the movable base 40 and are inserted into the base 10. The insert rods 65 are equipped with scale plates. The drive component is located inside the base 10 and drives the two lead screws 61 to rotate synchronously. The base 10 has a cavity inside. The drive component includes sprockets 62, a chain 63, and a geared motor 64. The two sprockets 62 are fixedly located at the bottom ends of the two lead screws 61 that extend into the cavity, and are rotatably connected inside the cavity. The chain 63 is meshed with the outside of the two sprockets 62. The geared motor 64 is fixedly installed at the bottom of the cavity. The output shaft of the geared motor 64 is fixedly connected to one of the sprockets 62. The geared motor 64 slowly drives the sprocket 62 to rotate, causing the sprocket 62 to drive the chain 63 meshing with it to rotate in the cavity. The chain 63 drives the other sprocket 62 to rotate synchronously, so that the two sprockets 62 can drive the lead screw 61 to rotate synchronously. The rotation of the lead screw 61 causes the movable seat 40 threaded to it to move up and down. The two sprockets 62 limit the movement of the movable seat 40 to prevent the movable seat 40 from rotating with the lead screw 61. The movement of the movable seat 40 causes the limit height of the buffer seat 51 to change accordingly, so as to adapt to the pressing height of the hot press plate on the plate of different thicknesses. This allows the hot press buffer structure to adapt to the processing of plates of different thicknesses. The scale on the scale plate on the two inserts 65 can show the thickness of the corresponding plate, so that the movement of the movable seat 40 can be more accurate.

[0022] Please refer to Figures 1-4 The bottom of the movable seat 40 is provided with a positioning component 70, which includes a threaded rod 71, a positioning plate 72, and limiting rods 73. The threaded rod 71 is threadedly connected to the bottom of the movable seat 40. The positioning plate 72 is slidably connected to the side of the movable seat 40 near the placement seat 30, and one end of the threaded rod 71 is rotatably connected to the positioning plate 72. The positioning plate 72 is in contact with the side of the plate. Two limiting rods 73 are respectively provided on both sides of the positioning plate 72. The two limiting rods 73 are inserted into the bottom of the movable seat 40, and the threaded rod 71 is positioned in contact with the bottom of the plate. The staggered position of the lead screw 61 does not obstruct the up-and-down movement of the movable seat 40 driven by the lead screw 61. The rotation of the threaded rod 71 drives the positioning plate 72, which rotates with it, to move inside the movable seat 40. The two limit rods 73 limit the movement of the positioning plate 72, allowing the positioning plate 72 to move to the side of the plate and limit the plate to prevent it from moving arbitrarily during the hot pressing process. The top height of the positioning plate 72 is lower than the maximum downward height of the buffer seat 51, so that the positioning plate 72 will not affect the hot pressing process when it is placed on the side of the plate.

[0023] The functional principle of this application can be explained through the following methods:

[0024] In use, the sheet material is placed on the placement seat 30 on top of the base 10. The height of the movable seat 40 is adjusted according to the required thickness after hot pressing. The reduction motor 64 inside the cavity is started, causing its output shaft to drive a sprocket 62 to rotate. The sprocket 62 drives the chain 63 meshing with it on the outside to rotate. The rotation of the chain 63 in the cavity causes the two inner sprockets 62 to rotate simultaneously. The synchronous rotation of the two sprockets 62 drives the two lead screws 61 to rotate synchronously, causing the movable seat 40, which is threaded to it on the outside, to move up and down, changing the height of the buffer seat 51 on top of the movable seat 40. When the movable seat 40 moves up and down, the insertion rod 65 passes through the base 10, limiting the movement of the movable seat 40. Observe the scale on the insertion rod 65 corresponding to the scale on the surface of the base 10. Stop the movement of the movable seat 40 near the position before reaching the required thickness after hot pressing, ensuring that the downward movement of the hot pressing plate does not exceed the downward limit of the buffer seat 51. When the threaded rod 71 is rotated, the threaded rod 71, which is threaded to the bottom of the movable seat 40, moves the positioning plate 72 toward the plate. The two limiting rods 73 limit the movement of the positioning plate 72, so that the two positioning plates 72 can contact the two sides of the plate and fix the plate on the placement seat 30 to prevent the plate from moving randomly during hot pressing. The hot pressing assembly 20 is started, and the hot pressing plate of the hot pressing assembly 20 moves down to the position of contact with the two buffer seats 51, so that the buffer seats 51 can move down in the slide groove 41 with the hot pressing plate. The downward movement of the buffer seats 51 causes the damper 52 and the spring 53 to contract accordingly. The elastic force of the spring 53 buffers the downward movement of the hot pressing plate and prevents the plate from deforming due to excessive pressure. When the buffer seats 51 move down to the stepped position in the slide groove 41, the buffer seats 51 stop moving down to prevent the spring 53 from exceeding the elastic limit. At this time, the hot pressing plate also processes the plate to the required thickness, so that the plate is fully pressed by the pressure and high temperature of the hot pressing plate, and the hot pressing work is completed.
