Abstract
The invention provides an upper hydraulic cushion of a single action hydraulic press slider, which is characterized in that on the front and rear sides of the hydraulic press slider, a row of grooves parallel to the lower surface of the slider is made. The insides of all grooves are all provided with the knockout plates with top-down movement, which are also made and distributed with a row of mandril holes leading to the lower surface of the slider. On the front and rear sides of the slider, the front pressure boards linked with the front end of each knockout plate and the rear pressure boards linked with the rear end of each knockout plate are respectively installed, and eight upper hydraulic cushion fuel tank driving the top-down movement of the front and rear pressure boards are also arranged. Through the knockout plates driven through the upper hydraulic cushion fuel tank and the mandril movement arranged inside the mandril holes, the front stretching movement of the work-piece is achieved, and the application range of the single-action hydraulic press is expanded. In addition, the invention also has the advantages of simple structure, easy manufacturing and low costs.
Description
Technical field
The present invention relates to a kind of single action hydraulic press that is used for the thin plate tensioning member, especially a kind of last hydraulic die cushion device of single action hydraulic press slide block.
Background technology
Single action hydraulic press is widely used in processing such as the reverse-drawing, bending, moulding, blanking blanking, flange of workpiece, no matter single action hydraulic press is at applying working condition, still comparing in the energy resource consumption with on the equal parameter of large-scale double action hydraulic press, all have great advantage, the structure of known single action hydraulic press mainly is: entablature and sill, be installed in two lateral braces between entablature and the sill, be installed in the slide block that moves up and down between two lateral braces, travelling table is installed on the plane on the sill, the sliding block that is moved up and down by hydraulic oil cylinder driving is installed in the sill.The single action hydraulic press of this structure can only rely on sliding block to finish reverse-drawing processing, but just can't finish for the workpiece of forward and reverse stretching.
Summary of the invention
But the present invention provides a kind of last hydraulic die cushion device of single action hydraulic press slide block of forward stretching for solving the technical problem that exists in the known technology.
The technical scheme that the present invention takes for the technical problem that exists in the solution known technology is:
A kind of last hydraulic die cushion device of single action hydraulic press slide block, be included in the slide block that moves up and down in the hydraulic machine column, the row that the slide block lower plane vertically is shaped on is used for the T-slot of installation mold, drive the master cylinder and the side cylinder of slide block movement, vertically be shaped on the row groove parallel on the front-back of described slide block with the slide block lower plane, in groove, vertically be shaped on the row's jogger hole that leads to the slide block lower plane, a knockout plate that moves up and down all is installed in each groove, be horizontally installed with a front pressuring plate that is connected with each knockout plate front end and a rear fender that is connected with each knockout plate rear end on the front-back of slide block respectively, hydraulic die cushion oil cylinder on being vertically installed with respectively on the front-back of slide block that several drive that front pressuring plates and rear fender move up and down.
The advantage that the present invention has with good effect is: because a row knockout plate parallel with the slide block lower plane vertically is installed in slide block, on the slide block lower plane, be shaped on the several rows of jogger hole of corresponding dnockout, on the front-back of slide block, be separately installed with front pressuring plate that is connected with each knockout plate front end and the rear fender that is connected with each knockout plate rear end, be separately installed with on the slide block front-back several drive front pressuring plates and rear fender motion on the hydraulic die cushion oil cylinder, by last hydraulic die cushion hydraulic oil cylinder driving knockout plate and be installed in push rod in the jogger hole, the forward of finishing workpiece stretches and moves, thereby has enlarged the scope of application of single action hydraulic press; In addition the present invention also have simple in structure, be easy to make, advantage that cost is low.
Description of drawings
Fig. 1 is a structural representation of the present invention;
Fig. 2 is the left view of Fig. 1;
Fig. 3 is the A enlarged drawing of Fig. 1;
Fig. 4 is the B enlarged drawing of Fig. 2.
Among the figure: 1, slide block; 2, go up the hydraulic die cushion oil cylinder; 3, front pressuring plate; 4, fixed head; 5, L shaped connecting plate; 6, knockout plate; 7, square key; 8, groove; 9, T-slot; 10, rear fender; 11, jogger hole.
The specific embodiment
For further understanding summary of the invention of the present invention, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, the lower plane of slide block 1 vertically is shaped on row's T-slot 9, on the front and back sides of slide block, vertically be shaped on the row groove 8 parallel with the slide block lower plane, the knockout plate 6 that moves up and down all is installed in each groove, the interior uniform jogger hole 11 that a row is led to the slide block lower plane that is shaped on of each groove, as shown in Figure 2.On the front side of slide block and trailing flank, be separately installed with front pressuring plate 3 that is connected with each knockout plate front end and the rear fender 10 that is connected with each knockout plate rear end, also be equipped with on the leading flank of slide block and the trailing flank eight drive that front pressuring plates and rear fender move up and down on hydraulic die cushion oil cylinder 2.Hydraulic die cushion oil cylinder upper end is installed on the front and back sides of slide block by square key 7 and fixed head 4 on each, and hydraulic die cushion oil cylinder lower end connects front pressuring plate and rear fender by L shaped connecting plate 5 on each, as shown in Figure 3 and Figure 4.In the corresponding push rod of the upper mould hole site that slide block is installed push rod is installed like this, is moved up and down, finish the positive stretch process of product product thereby the driving push rod moves up and down by last hydraulic die cushion hydraulic oil cylinder driving knockout plate.
