Double-station hot press

Abstract

The invention discloses a double-station hot press which consists of a main body frame, a control system, a mechanical device, a heating device, a hydraulic device, an electrical executive device and a safety device, wherein the main body frame consists of a rack, upright columns, cross beams, stations and a protective cover; a bottom plate is arranged below the rack; a table plate is arranged on the top surface of the rack; the protective cover is arranged above the rack; the cross beams are internally provided with the independent stations; two electric cabinets assembled side by side are arranged at the front surface of the protective cover; the control system comprises the electric cabinets and a console; the mechanical device comprises hydraulic cylinders, pistons, upper beating plates, lower beating plates and guide rods; the number of the hydraulic cylinders is two; and the heating device comprises heating rods, heating plates, heat insulating plates and heatproof covers. With the adoption of the double-station hot pressing design, the operation is simplified, the floor space is small, the pressure is stabile; the temperatures and movements of the upper heating plates and the lower heating plates are controlled separately, and alternate no-break operation is facilitated. Compared with a single-station machine, the productive capacity of the double-station hot press is increased by more than a half.

Description

technical field [0001] The invention relates to the technical equipment field of a hydraulic press, in particular to a double-station hot press. Background technique [0002] With the development of the society, the technology is constantly improving. There are many types of hydraulic presses, which are usually used in various PC, PVC, PET and other membrane switches to form concave and convex surfaces, replacing traditional cold punching machines, one-time forming without scrapping, and received by domestic and foreign customers. Unanimous praise; it can also be used for other metal (non-metal) thermoforming, such as: flexible circuit board pressing, computer heat dissipation copper pipe, various non-metal welding, etc., and the hot pressing part can be closed for other assembly and stamping purposes. [0003] In the currently known technology, the hydraulic press usually uses a single-station mobile worktable or a multi-station mobile workbench to replace the mold. When a ...

AI Technical Summary

Problems solved by technology

[0003] In the currently known technology, the hydraulic press usually uses a single-station mobile worktable or a multi-station mobile workbench to replace the mold. When a single-station mobile workbench is used, since it has only one station for placing the mold, the The replacement operation can only be done after the previous pressure processing process is completed, and the operator is in a waiting state. After the processing is completed, the worktable can be moved out of the hydraulic press to replace the mold, and it can only be performed by manual assistance. Therefore, the mold change time is long, and multiple mobile worktables are used. At the same time, although the mold change time is reduced, the floor area is large. At the same time, because the above two forms of mobile workbench are used as the mold change mechanism of the hydraulic press and as the workbench, it is not only necessary to install the drive required for the movement device, but also increase the rigidity of the structure to withstand huge pressure, resulting in a complex and cumbersome structure of the mobile work table

[0004] Most of the hydraulic presses in the prior art are equipped with a single processing station, which cannot meet the needs of forming processing. The mold replacement speed is slow, the operation is complicated, the hot pressing processing efficiency is low, the equipment utilization rate is low, and the labor cost is high.
