Abstract
The utility model discloses a kind of flattening mold tooling, comprise dip mold, core, top die and top board, upper and lower pressing mold has corresponding semi-circular recesses structure, and there is in the groove of top die the through hole of through top die, core is that side has the cylinder of planar structure and is arranged in described groove structure, described top board comprises inner panel and outside plate, outside plate is enclosed within outside inner panel, described top die is fixedly connected with outside plate, depression bar is provided with bottom described inner panel, described depression bar is installed in the through hole of top die, and the lower end of depression bar arranges pressure head.First shock absorber outer tube is fixed or pre-pressing by upper dip mold and core, on outer tube, flattening operation is carried out again by pressure head, effectively can avoid the generation of the situations such as outer tube slip skew, ensure the stability raising flattening quality and operating efficiency of flattening operation.
Description
Technical field
The utility model relates to shock absorber production and processing device technique field, particularly relates to a kind of frock being applicable to shock absorber outer tube flattening operation.
Background technology
At present, for the production of cylinder shock absorber, usually need in process, to carry out flattening operation to a certain position of the outer tube of shock absorber, due to the circular configuration feature of outer tube, and pressure head is generally planar structure, in pressing process, easily cause outer tube to slide, pressure action direction offsets, cause flattening the situations such as position inclination to occur, have a strong impact on the quality of production of shock absorber, percent defective is increased, and production efficiency is low.
Utility model content
For the deficiency that prior art exists, it is simple, easy and simple to handle that the utility model object is to provide a kind of structure, effectively can avoid the flattening mold tooling that in pressing process, shock absorber outer tube slip drift condition occurs.
To achieve these goals, the utility model realizes by the following technical solutions: a kind of flattening mold tooling, comprise dip mold, core, top die and top board, upper and lower pressing mold has corresponding semi-circular recesses structure, and there is in the groove of top die the through hole of through top die, core is the cylinder that side has planar structure, and be arranged in described groove structure, described top board comprises inner panel and outside plate, outside plate is enclosed within outside inner panel, described top die is fixedly connected with outside plate, depression bar is provided with bottom described inner panel, described depression bar is installed in the through hole of top die, the lower end of depression bar arranges pressure head.
Described dip mold is provided with the guide post running through top die and inner panel.
Guide post between described inner panel and top die is arranged with spring.
The end face of described top die is provided with spacing magnet.
First flattening mold tooling of the present utility model is fixed or pre-pressing shock absorber outer tube by upper dip mold and core, on outer tube, flattening operation is carried out again by pressure head, effectively can avoid the generation of the situations such as outer tube slip skew, ensure the stability raising flattening quality and operating efficiency of flattening operation.Preferably, dip mold is provided with the guide post running through top die and inner panel, the stability of upper dip mold, inner panel and pressure head is ensured by guide post, the outer tube of shock absorber and pressure head are kept on one wire up and down, can further improve the stability and flattening quality of flattening operation, product percent of pass can reach more than 99%.Further, the volume under pressure required for workpiece is flattened according to waiting, top die and spacing magnet is set between top board, can the volume under pressure of effective guarantee pressure head, avoid the situations such as the volume under pressure that causes because travel switch is malfunctioning is excessive, workpiece is yielding, simultaneously, effectively can reduce that mould is impaired, the extension device life-span, change a mould by about 20,000 before, and after flattening, workpiece is easily out of shape, and changes about 80,000 after use into and changes a mould and dimensionally stable.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the generalized section of top die.
Detailed description of the invention
Below in conjunction with detailed description of the invention, set forth the utility model further.
As Fig. 1, shown in Fig. 2: a kind of flattening mold tooling, comprise dip mold 1, core 11, top die 3 and top board, upper and lower pressing mold has corresponding semi-circular recesses structure 10, and there is in the groove of top die 3 through hole 12 of through top die 3, core 11 has the cylinder of planar structure for side, and be arranged in the groove structure 10 of dip mold 1, described top board comprises inner panel 5 and outside plate 4, outside plate 4 is enclosed within outside inner panel 5, inner panel 5 can slide up and down in outside plate 4, outside plate 4 is all connected with compression cylinder with inner panel 5, described top die 3 is fixedly connected with by connecting rod with outside plate 4, depression bar 6 is provided with bottom described inner panel 5, described depression bar 6 is installed in the through hole 12 of top die 3, the lower end of depression bar 6 arranges pressure head 9.Described dip mold 1 arranges guide post 2, top die 3 and inner panel 5 are provided with corresponding pilot hole 13, guide post 2 passes the pilot hole 13 of top die 3 and inner panel 5 successively, guide post 2 between described inner panel 5 and top die 3 is arranged with spring 8, and the end face of top die 3 arranges spacing magnet 7, and spacing magnet 7 is positioned at the below of inner panel 5.
During operation, first shock absorber outer tube sleeve is placed in the groove of dip mold 1 on core 11, the side that core has planar structure remains upwards, then descend coping, outside plate 4 and inner panel 5 can be pressed down simultaneously, make top die 3 by shock absorber outer tube pre-pressing, shock absorber outer tube is made to keep stable, avoid the situation such as rotation to occur, and then press down separately inner panel 5, make pressure head 9 that shock absorber outer tube waited that flattening position is depressed into appropriate level.After having pressed down, promote top board, top die 3 and pressure head 9 are restPosed, presses down next time.In process, top die 3, top board, depression bar 6, pressure head 9 are all guiding with guide post, keep stablizing, avoiding skew; When spacing magnet makes inner panel 5 press to suitable distance, keep stable, and make pressure head 9 keep certain hour to the pressure of work, pressure head 9 is avoided to withdraw rear workpiece deformation, avoid the time delay etc. only adopting travel switch to cause to make to press down excessively simultaneously, cause workpiece to scrap, the situation such as burn failure, spring failure.
