Description

Technical Field

[0001] The invention relates to the field of steel-plastic composite plate processing equipment, in particular to a steel-plastic composite plate edge pressing forming equipment. Background Art

[0002] In recent years, aluminum alloys used in vans have been gradually replaced by steel-plastic composite panels, which offer significant advantages over the original aluminum alloy. First, the combined thickness of the outer skin and inner lining is reduced. This thinner body allows for more space inside the van, allowing for greater flexibility when transporting on pallets. Second, steel-plastic composite panels are stronger than aluminum alloys. Aluminum alloys are lightweight but easily damaged, and any collision can damage an aluminum alloy body. Using steel-plastic composite panels significantly reduces this damage rate.

[0003] Adjacent steel-plastic composite panels are typically joined together using connecting plates and rivets, which are then joined one by one to form a box or other structure. To ensure a generally flat surface at the joint and prevent the connecting plates and rivets from protruding from the composite panel surface, the edges of the joints must be pressed during processing, creating a pressure edge approximately 28mm wide and 1mm deep. This pressure edge requires slightly different widths and depths for different composite panel sizes and customer needs, requiring replacement or adjustment, requiring a high level of operational experience. Furthermore, conventional straight-up and straight-down stamping methods can significantly affect the internal texture of these steel-plastic composite panels, especially at the pressure edge interface. This issue urgently needs to be addressed. Summary of the Invention

[0004] In view of this, the purpose of the present invention is to provide a forming equipment for edge pressing of steel-plastic composite panels, by which the edge pressing of steel-plastic composite panels can be performed, which facilitates the replacement and adjustment operations to a certain extent, so as to adapt to the edge pressing of steel-plastic composite panels and improve product production efficiency and quality.

[0005] To achieve the above objectives, the technical solutions adopted by the present invention are as follows:

[0006] The present invention provides a forming device for edge pressing of a steel-plastic composite plate, comprising:

[0007] a main body, on which a lifting frame driven by a hydraulic cylinder is provided, and a workbench is provided directly below the lifting frame; and

[0008] The edge pressing assembly includes: a mounting plate and a pressure plate; the mounting plate is detachably mounted on the bottom of the lifting frame, a stamping plate is provided at the bottom of the mounting plate, and the bottom surface of the stamping plate has a stamping surface; the pressure plate can also be detachably mounted on the workbench, and the upper end surface of the pressure plate has a pressure surface. When the bottom surface of one side of the steel-plastic composite plate moves to the pressure surface, the stamping plate moves downward to perform edge pressing on the upper end surface of the side of the steel-plastic composite plate through the stamping surface.

[0009] In some embodiments, the stamping plate is arranged on the mounting plate for horizontal movement, and one side of the stamping surface has a stamping slope; correspondingly, one side of the pressure-bearing surface has a pressure-bearing slope. When the stamping surface performs edge pressing on the upper end surface of the steel-plastic composite plate, the stamping slope and the pressure-bearing slope cooperate to make the stamping plate move toward the side end surface of the edge pressing.

[0010] In some embodiments, a step is provided at the intersection of the pressure-bearing surface and the pressure-bearing inclined surface for limiting the side end surface of the steel-plastic composite panel at the edge pressing portion.

[0011] In some embodiments, it further includes: a pad, the upper end surface of the pad is detachably mounted on the bottom of the lifting frame, and the stamping plate is mounted on the lower end surface of the pad.

[0012] In some embodiments, it further includes: a support block, the upper end of the support block is detachably mounted on the mounting plate, and the lower end of the support block is connected to the stamping plate.

[0013] In some embodiments, it further includes clamping plates arranged on both sides of the pressure plate, and the clamping plates are detachably mounted on the workbench.

[0014] In some embodiments, a dovetail groove is provided at the bottom of the lifting frame.

[0015] In some embodiments, vertical guide rails for guiding the lifting frame are provided on opposite sides of the main body.

[0016] In some embodiments, the hydraulic cylinder includes a master cylinder and two side cylinders.

[0017] In some embodiments, a protective layer is provided on the stamping surface.

[0018] Compared with the existing technology, the beneficial effect of the steel-plastic composite board edge pressing forming equipment provided by the present invention is: the steel-plastic composite board is pressed by the equipment, which is convenient for replacement and adjustment operations to adapt to the edge pressing processing of the steel-plastic composite board and improve product production efficiency and quality.

[0019] Compared with the ordinary straight up and down stamping, the present invention applies force to the side end face of the plate while pressing downward. On the one hand, it avoids the cliff-like tearing inside the compression boundary of the steel-plastic plate and affects the strength of the plate. On the other hand, it allows the compression boundary of the steel-plastic plate to have a smooth transition with an inclined trend, greatly reducing stress concentration, thereby greatly improving the strength of the compression boundary surface.

[0020] The invention has a simple structural design and is easy to use, which brings great convenience to the operator, improves the quality and economic benefits of the product, and is worthy of widespread promotion and use. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below with reference to the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the scope of protection of the present invention.

[0027] Example 1

[0028] In a specific embodiment, see Figures 1 to 3 The embodiment of the present invention provides a forming device for edge pressing of a steel-plastic composite panel, comprising:

[0029] A main body 40 is provided with a lifting frame 401 driven by a hydraulic cylinder 400, i.e., the hydraulic cylinder 400 is vertically arranged with its telescopic end facing downward and fixedly connected to the lifting frame 401, and a workbench 402 is provided directly below the lifting frame 401; and

[0030] The edge pressing assembly includes: a mounting plate 41 and a pressure plate 42; the mounting plate 41 is detachably mounted on the bottom of the lifting frame 401 and can be fixed by bolts, and a stamping plate 411 is provided at the bottom of the mounting plate 41, and the bottom surface of the stamping plate 411 has a stamping surface, and the length and width of the stamping surface can be adapted to the plate surface to be stamped; the pressure plate 42 can also be detachably mounted on the workbench 402, and the upper end surface of the pressure plate 42 has a pressure surface, which is used to support the bottom surface of the steel-plastic composite board. When the bottom surface of one side of the steel-plastic composite board moves to the pressure surface, the stamping plate 411 moves down and performs edge pressing on the upper end surface of the side of the steel-plastic composite board through the stamping surface.

[0031] During specific use, one side of the steel-plastic composite board is moved and sent onto the pressure surface of the pressure plate 42, and then the lifting frame 401 is driven downward by the hydraulic cylinder 400, so that the stamping surface of the bottom of the stamping plate 411 performs edge pressing on the steel-plastic composite board. However, the stamping plate 411 and the pressure plate 42 can be made into different specifications. For example, the width of the bottom of the stamping plate 411 determines the edge pressing width, and the height of the stamping plate 411 and the pressure plate 42 can determine the edge pressing depth. In this way, without changing the equipment program parameters, components with different required edge pressing sizes can be quickly replaced, thereby achieving the purpose of facilitating replacement and adjustment operations, so as to adapt to the edge pressing processing of the steel-plastic composite board, reduce the operating experience requirements, and thus ensure product production efficiency and product quality.

[0032] Example 2

[0033] Based on the first embodiment, in order to obtain a better texture for the compressed interior of the steel-plastic plate, optionally, the stamping plate 411 is arranged on the mounting plate 41 along the lateral movement, that is, a slide groove is provided at the bottom of the mounting plate 41 along the width direction, and a sliding tooth cooperating with the slide groove is provided on the top of the stamping plate 411, and one side of the stamping surface has a stamping inclined surface 410; correspondingly, one side of the pressure-bearing surface has a pressure-bearing inclined surface 420. When the stamping surface performs a pressing process on the upper end surface of the steel-plastic composite plate, the stamping inclined surface 410 cooperates with the pressure-bearing inclined surface 420 to make the stamping plate 411 move toward the side end surface of the pressing edge, that is, move away from the center of the composite plate surface. In order to allow the stamping plate 411 to reset when the inclined surfaces are separated, a plurality of tightening springs for elastically tightening the stamping plate 411 in opposite directions are provided at the bottom of the mounting plate 41, such as Figure 3As shown, the distances of the lateral movement and the vertical movement of the stamping plate 411 can be adjusted to be basically the same; in this way, compared with the ordinary straight up and down stamping, the stamping surface presses down while applying force to the side end surface of the plate, on the one hand, it avoids the cliff-like tearing inside the compression boundary of the steel-plastic plate and affects the strength of the plate, on the other hand, it allows the compression boundary of the steel-plastic plate to have a smooth transition with an inclined trend, greatly reducing stress concentration.

[0034] Furthermore, the intersection of the pressure-bearing surface and the pressure-bearing inclined surface 420 has a step for limiting the side end surface of the steel-plastic composite board at the edge pressure. The height of the step is lower than the thickness of the composite board to prevent the board from being horizontally shifted when under pressure, and it can also prevent the side end surface of the board from bulging outward and deforming when under pressure, thereby avoiding affecting splicing and use.

[0035] Example 3

[0036] The above embodiment also includes: a pad 412, the upper end surface of the pad 412 is detachably mounted on the bottom of the lifting frame 401, and can be fixedly installed by bolts, and the lower end surface of the pad 412 is installed with the stamping plate 411. The height of the pad 412 can be made into different specifications to adapt to the installation when stamping different products without adjusting other parameters of the equipment.

[0037] The above embodiment further includes: a support block 413 , the upper end of the support block 413 is detachably mounted on the mounting plate 41 , and the lower end of the support block 413 is connected to the stamping plate 411 to increase the stamping strength of the stamping plate 411 .

[0038] The above embodiment also includes clamping plates 421 relatively arranged on both sides of the pressure plate 42, which can adjust the lateral distance of the pressure plate 42. The clamping plates 421 can be detachably installed on the workbench 402, that is, they can be installed by bolts, and the height and width of the pressure plate 42 can be made into different specifications to adapt to the stamping processing of different products without the need to adjust the stamping parameters separately.

[0039] In the above embodiment, a dovetail groove is provided at the bottom of the lifting frame 401, and the length of the dovetail groove is opened in the direction close to or away from the pressure plate. The mounting plate 41 can be installed in the dovetail groove by bolts and dovetail nuts to facilitate coarse lateral adjustment of the position.

[0040] In the above embodiment, vertical guide rails 43 for guiding the lifting frame 401 are provided on opposite sides of the main body 40 .

[0041] In the above embodiment, the hydraulic cylinder 400 includes a main cylinder and two side cylinders. The main cylinder is arranged in the middle position, and the side cylinders are arranged at both sides to increase pressure stability.

[0042] In the above embodiment, a protective layer is provided on the stamping surface, which may be made of high-strength plastic to prevent surface damage of the product during stamping.
