Embodiment Construction

[0018] The present invention will be described in further detail below in conjunction with the accompanying drawings and examples.

[0019] see image 3 , Figure 4 , the present embodiment is a prestressed press machine with a double winding structure, which is composed of a front frame 2, a rear frame 3, a left beam 4 and a right beam, the front frame 2 and the rear frame 3 are arranged side by side, and the front frame The frame 2 and the rear frame 3 are welded and connected by the horizontal left beam 4 and the right beam (not shown in the figure). The front frame 2 and the rear frame 3 have the same structure. The rear ear seat 3-2, the rear lower semicircular beam 3-3, the rear left column 3-4, the rear upper semicircular beam 3-5, the rear oil cylinder platform 3-6 and the rear right column (not shown in the figure), the front The frame 2 and the rear frame 3 constitute a hollow box-shaped structure.

[0020] Front frame 2 is made of front base 2-1, front lower semi...

Abstract

The invention relates to a prestress press, in particular to a prestress press with double winding structures. The device comprises main racks, each main rack comprises a base and a lower semicircularbeam arranged on the base, stand columns are arranged on the upper portions of the two ends of each lower semicircular beam, upper semicircular beams are arranged on the stand columns, the two main racks are the front rack and the rear rack respectively, the front rack and the rear rack are arranged in parallel in an aligned mode, and the stand columns of the front rack and the stand columns of the rear rack are fixedly connected through beams. A front and rear main rack assembling structure is adopted, and each main rack is provided with one steel wire winding structure, so that main rack bodies have excellent anti-fatigue performance; and when the prestress press is particularly used for a large-tonnage rack, the manufacturing, machining, transporting and mounting difficulty of a mechanical body can be effectively reduced, and the problems that an existing single-main-rack winding type press is large in size, heavy in weight, difficult to manufacture, machine and transport and highin requirement for a winding device are solved.

Description

technical field [0001] The invention relates to a prestressed press, in particular to a prestressed press with a double winding structure. Background technique: [0002] At present, the steel wire winding prestressing press ( figure 1 , figure 2 ), its main frame is an overall structure composed of upper and lower semicircular beams and left and right columns. By pre-tightening the frame by using steel wire winding, compared with the welded frame, the steel wire winding frame transfers the tensile stress generated during work to the steel wire, so that the frame is always in a state of compressive stress, thereby reducing the fatigue strength of the press frame. However, when the overall frame composed of upper and lower semicircular beams and left and right columns is used in a process with a large table, the column of the press is super wide and heavy, which brings troubles to processing and transportation, and the production cost is also high. Huge improvements. When...
