Description

Technical Field

[0001] This application belongs to the field of sheet metal production equipment, and more specifically, it relates to a clutch-type hot press sheet metal thickness adjustment device. Background Technology

[0002] Existing hot presses mostly use hydraulic systems to adjust the thickness of plates, but this has significant limitations in adjusting the product thickness. See Chinese Patent Publication No. CN118775377A, which discloses an automatic leveling synchronous large plate hot press hydraulic system based on deviation detection, specifically disclosing the following technical solution: a synchronization control module to ensure the upper pressure plate is synchronized in the width direction during lifting, improving processing accuracy; and an adjustable pressure range module to adjust the pressure range to adapt to the processing needs of plates of different lengths and protect the equipment. This application, through the synchronization control module, can ensure the upper pressure plate is synchronized in the width direction during lifting, thereby effectively avoiding deformation of the plate due to uneven force during processing and significantly improving processing accuracy. This is particularly important for plates requiring high-precision processing, improving the overall product quality. The adjustable pressure range module allows adjustment of the pressure range according to plates of different lengths and thicknesses, enabling the equipment to flexibly cope with diverse processing needs.

[0003] Similarly, existing technologies also include patent documents such as Chinese Patent Publication No. CN117246026A, which discloses a composite board production line with surface roughening and pressing treatment, and specifically discloses the following technical solution: including a processing production line table, a support frame, a moving component, a processing component, a press base, a pressing component, and a height setting component. The support frame includes two mounting plates, with four first support columns vertically and symmetrically arranged between the two mounting plates. A board roughening and leveling mechanism and a hot pressing mechanism are respectively arranged on both sides of the processing production line table. When the board is reprocessed, it is quickly leveled and roughened in conjunction with the moving component and the processing component. After the processing is completed, it is quickly pressed with precise thickness in conjunction with the pressing component and the height setting component. During the pressing operation, the edges of the board are pressed with high quality under the relative action of several second pressure cylinders. The processing operation is simple, convenient to use, and the product quality and efficiency are high.

[0004] In other words, in the existing structure of hot presses, the adjustment of the thickness of sheet products is mostly achieved through mechanical structures including hydraulic systems or height setting components. However, the adjustment range is limited, and it is impossible to press sheet thicknesses outside the adjustment range, which has significant limitations. Summary of the Invention

[0005] The purpose of this application is to provide a slab thickness adjustment device for a clutch-type hot press, which can achieve the pressing of slabs of various thicknesses by replacing pads of different weight specifications in the clutch-type hot press under the condition that the closing time, pressurization time and hydraulic oil volume are the same.

[0006] To achieve the above objectives, this application employs the following technical solution:

[0007] The clutch-type hot press slab thickness adjustment device described in this application includes a pad support, which is a frame structure. Support guide plates are provided on both sides of the inlet of the pad support. An upper pad and a lower pad are connected to the pad support through the support guide plates. The lower pad is located below the upper pad. Both the upper and lower pads are provided with positioning plates.

[0010] As one of the preferred technical solutions of this application, the lower pad block is provided with pulley placement grooves on both sides of the slot, and pulley groups are provided in the pulley placement grooves.

[0011] As one of the preferred technical solutions of this application, the pulley group includes a long strip-shaped U-shaped plate, a supporting pulley is rotatably arranged inside the U-shaped plate along its length direction, a connecting plate for connecting the U-shaped plate is arranged inside the lower pad, and a compression spring is arranged between the connecting plate and the U-shaped plate.

[0012] As one of the preferred technical solutions of this application, the upper pad and the lower pad are provided with connecting plates on the end faces of the pad support near the inlet of the pad support, and the connecting plates are connected to the pull rod.

[0013] As one of the preferred technical solutions of this application, the bottom of the pad support is connected to a support triangular rib by a bolt assembly, and the support triangular rib is located on the frame at the installation position.

[0014] Compared with the prior art, the beneficial effects of this application are:

[0015] This application improves the convenience, stability, and reliability of the connection between the pads and the pad supports by setting up multiple pad supports that can be arbitrarily combined, and by redesigning the connection structure and assembly method between the pads and the pad supports. This allows for the replacement of pads of different weights and specifications on a single hot press machine, thereby enabling the pressing of different sheet thicknesses and thus improving the pressing function of the hot press machine.

[0028] The structure and connection relationships of the remaining parts are the same as those described in the foregoing embodiments.

[0029] Based on the above embodiments, the following paragraphs will continue to describe in detail the technical features involved and the functions and roles of these technical features in this technical solution, so as to help those skilled in the art to fully understand the technical solution and reproduce it.

[0030] In this application, the pad support 1 is a frame structure with a U-shaped cross-section, which forms an entrance at one end. Multiple support guide plates 6 are provided on both sides of the entrance. The pad support 1 is connected and placed with the upper pad 2 and the lower pad 3 through the support guide plates 6.

[0031] In this application, the upper pad 2 and lower pad 3 can be configured as a box structure, with a counterweight inside the box structure to adjust the weight of the pads. Alternatively, in this application, the upper pad 2 and lower pad 3 can be blocks of constant weight.

[0032] In this application, the top end face of the upper pad 2 and the lower pad 3 is provided with a slot 9 at the middle position. The slot 9 can slide and cooperate with the guide block 10 on the adjacent upper pad 2 or lower pad 3 to limit the guide block 10.

[0033] In this application, the lower pad 3 has pulley placement grooves at the top end faces on both sides of the slot 9. A pulley assembly 11 is installed inside the pulley placement grooves. The pulley assembly 11 includes a U-shaped plate 15 and a supporting pulley 16 located within the U-shaped plate 15. The supporting pulley 16 can achieve sliding contact and support with the bottom surface of the corresponding upper pad 2 or lower pad 3. A connecting plate for connecting the U-shaped plate 15 is installed inside the lower pad 3. A compression spring is installed between the U-shaped plate 15 and the connecting plate. The compression spring ensures stable contact between the pulley assembly 11 and the bottom surface of the corresponding upper pad 2 or lower pad 3. A guide rod connected to the U-shaped plate 15 is also provided at the location of the compression spring, with the guide rod at the bottom of the U-shaped plate 15 passing through a guide hole at the connecting plate.

[0034] In this application, the upper pad 2 and the lower pad 3 are connected to the pull rod 13 through the connecting plate 12 on the end face, and the upper pad 2 or the lower pad 3 can be pulled out from the pad support 1 through the pull rod 13.

[0035] In this application, the upper pad 2 and the lower pad 3 can be positioned and connected to the guide plate positioning hole 7 through the positioning plate 5, and then detachably connected to the pad bracket 1 through the guide plate positioning hole 7, so as to fix the upper pad 2 and the lower pad 3 in the pad bracket 1.

[0036] In this application, auxiliary plates 4 extending toward the inlet of the pad block bracket 1 are provided on both sides of the upper pad block 2 and the lower pad block 3. The auxiliary plates 4 are provided with auxiliary wheels 8. With the cooperation of the auxiliary wheels 8 and the bracket guide plate 6, the difficulty of pushing the upper pad block 2 and the lower pad block 3 into the pad block bracket 1 can be effectively reduced.

[0037] See Figure 3The pad support 1, upper pad 2, and lower pad 3 are distributed on the pad base support 17. By adjusting the number of upper pad 2 and lower pad 3, different counterweights can be achieved, thereby enabling the same configuration of hot press to adjust the pads and meet the requirements of hot pressing different sheet thicknesses, reducing the limitation of the hot press on sheet thickness requirements. By adding or removing upper pad 2 and lower pad 3 in the pad support 1, the closing time, pressurization time, and hydraulic oil volume of the hot press required for producing sheets of different thicknesses can be kept basically constant, which helps to save processing time and energy.

[0038] Finally, although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
