Abstract

The utility model relates to a frame-type double-direction positive-negative extension hydraulic machine which comprises a fixed workbench, a movable workbench, a cross beam, a stand column and a sliding block. The movable workbench is arranged on the fixed workbench, the cross beam is arranged right above the fixed workbench, the cross beam is connected with the fixed workbench through the stand column with four corners, the sliding block is connected on the stand column in sliding mode, and the sliding block is driven by main cylinders arranged on the cross beam. An upper hydraulic cushion is arranged inside the sliding block, the upper hydraulic cushion is driven by an upper hydraulic cushion cylinder arranged inside the sliding block, a plurality of upper ejector rods are arranged on the lower end face of the upper hydraulic cushion, and through holes enabling the upper ejector rods to stretch out are arranged in the lower end face of the sliding block. A lower hydraulic cushion is arranged inside the fixed workbench, the lower cushion is driven by a lower hydraulic cushion cylinder arranged inside the fixed workbench, a plurality of lower ejector rods are arranged on the upper end face of the lower hydraulic cushion, and through holes enabling the lower ejector rods to stretch out are arranged in the movable workbench. When the frame-type double-direction positive-negative extension hydraulic machine works, double-direction positive-negative extension is achieved, and the frame-type double-direction positive-negative extension hydraulic machine is flexible to use. When an automobile metal product with a step is compressed, the automobile metal product can be formed simply in one step, and the frame-type double-direction positive-negative extension hydraulic machine is high in working efficiency.

Description

The two-way positive and negative drawing hydraulic press of a kind of frame-type

Technical field

The utility model relates to the two-way positive and negative drawing hydraulic press of a kind of frame-type, particularly a kind of efficient height that stretches, the two-way positive and negative drawing hydraulic press of frame-type that precision is high.

Background technology

Frame type hydraulic press only deposits hydraulic die cushion usually in workbench when being used for the compacting of various thin plate class auto parts and components, this kind structure is when compacting step parts, owing to can only adopt the mode of simple tension.Need post forming during compacting, compacting efficient is low, and precision is difficult to control.

Summary of the invention

The technical problems to be solved in the utility model provides a kind of efficient height that stretches, the two-way positive and negative drawing hydraulic press of frame-type that precision is high.

For solving the problems of the technologies described above, the technical solution of the utility model is: the two-way positive and negative drawing hydraulic press of a kind of frame-type, comprise stationary work-table, travelling table, crossbeam, column and slide block, travelling table is set on the stationary work-table, crossbeam is set directly over the stationary work-table, crossbeam is connected with stationary work-table by four jiaos column, the slide block that is slidingly connected on the column, and slide block is driven by the master cylinder that is installed on the crossbeam; Its innovative point is: be provided with hydraulic die cushion in the described slide block, upper hydraulic die cushion is driven by the upper hydraulic cushion cylinder that is installed in the slide block, and some upper ejector pins are installed in the lower surface, and the lower surface of slide block has and holds the through hole that upper ejector pin stretches out; Be provided with lower hydraulic die cushion in the described stationary work-table, lower hydraulic die cushion is driven by the lower hydraulic cushion cylinder that is installed in the stationary work-table, and some lower push rods are installed in the upper surface of lower hydraulic die cushion, have on the movable table to hold the through hole that push rod stretches out.

The utility model has the advantage of: upper and lower hydraulic die cushion is set respectively in slide block and stationary work-table, thereby realizes two-way positive and negative drawing in when compacting, use flexibly, when press belt step automobile metal product, can one-shot forming, high efficiency.

Description of drawings

Fig. 1 is the two-way positive and negative drawing hydraulic press of the utility model frame-type structural representation.

The specific embodiment

As shown in Figure 1, comprise stationary work-table 1, travelling table 2, crossbeam 3, column 4, slide block 5, master cylinder 6.

On the above-mentioned stationary work-table 1 travelling table 2 is set, crossbeam 3 is set directly over the stationary work-table 1, crossbeam 3 is connected with stationary work-table 1 by four jiaos column 4, the slide block 5 that is slidingly connected on the column 4, and slide block 5 is driven by the master cylinder 6 that is installed on the crossbeam 3.In this enforcement, master cylinder 6 is three.

Be provided with hydraulic die cushion 7 in the slide block 5, upper hydraulic die cushion 7 is driven by the upper hydraulic cushion cylinder 8 that is installed in the slide block 5, and some upper ejector pins 9 are installed in upper hydraulic die cushion 7 lower surfaces, and the lower surface of slide block 5 has and holds the through hole that upper ejector pin 9 stretches out.

Be provided with lower hydraulic die cushion 10 in the stationary work-table 1, lower hydraulic die cushion 10 is driven by the lower hydraulic cushion cylinder 11 that is installed in the stationary work-table 1.Some lower push rods are installed in the upper surface of lower hydraulic die cushion 10, have on the movable table 2 to hold the through hole that push rod stretches out.
