Abstract
The invention relates to a punching machine with adjustable punching stroke, which includes machine stand, flywheel, clutch, crankshaft, connecting rod, slide block. The slide block is located in the chute of the machine stand, upper of which is connected with bulb tee through connecting rod. The slide block is consisted of upper block and down block. Underpart of the upper block is equipped with a pull-rod, and the down block is provided with a pull-hole. The pull-rod is passed through the pull-hole of the down block, and there remains a cavity under the pull-rod end in the pull-hole. The pull-rod is connected with the upper block by screw. When punching, the pull-rod retracts into the down block, and the upper block drives the down block for punching operation. When restoring position, the upper block goes upside, the pull-rod is pulled out, and the slide block is pulled at the end of the stroke. Thus, the stroke of the down block is short, and hands of operators can not enter the mould for opening angle of the mould is small, then safety of using is guaranteed.
Description
Technical field
The present invention relates to press, particularly to the improvement of punch press.
Background technology
Punch press is to utilize flywheel rotation store kinetic energy, drives bent axle, connecting rod by arrangement of clutch, drives slide block at last, is converted into pumping of slide block, and kinetic energy is discharged, and carries out stamping press.Because the stroke size of slide block equals the tactical diameter of bent axle, is fixed value, the opening and closing range size of mould equals the stroke size.At present, the stroke of slider of punch is bigger, and operator's hand can enter in the mould, causes industrial accident easily.
Summary of the invention
The object of the invention is the punch press that provides a kind of stroke little and adjustable operator's hand to be entered in the mould, with the safety that guarantees to use.
The solution of the present invention is: the punch press of adjustable punching stroke, comprise support, flywheel, clutch, bent axle, connecting rod, slide block, slide block is installed in the chute of support, its top is connected by the bulb ball socket structure with connecting rod, slide block is made up of top shoe and sliding block, the bottom of top shoe is provided with pull bar, and sliding block is provided with pulling eye, and pull bar is buckled in the pulling eye of sliding block.
In the pulling eye of sliding block, leave cavity in the bottom of pull bar termination.
Between pull bar and top shoe by being threaded.
Advantage of the present invention is: owing to the slide down interblock connects with pull bar, during punching press, in the pull bar indentation sliding block, top shoe promotes sliding block, carry out stamping press, when resetting, top shoe is up, pull bar is pulled out, at the end pulling sliding block of its stroke, thereby the stroke of sliding block is little, and promptly the aperture of mould is little, operator's hand can not enter in the mould, has guaranteed the safety of using.In addition,, can pass through the threaded adjusting pull bar, regulate the stroke size of sliding block according to different needs.
Description of drawings
The invention will be further described with embodiment with reference to the accompanying drawings below.
Fig. 1 is the structural representation of Slipper of the present invention.
Fig. 2 is a generalized section.
1 connecting rod among the figure, 2 ball seats lid, 3 top shoes, 4 pull bars, 5 sliding blocks, 6 mould fixed screws.
The specific embodiment
The punch press of the adjustable punching stroke of embodiment comprises support, flywheel, clutch, bent axle, connecting rod, slide block, and slide block is installed in the chute of support, and its top is connected by the bulb ball socket structure with connecting rod 1, and this is identical with existing structure.
The structure of Slipper as depicted in figs. 1 and 2, slide block is made up of top shoe 3 and sliding block 5, the bottom of top shoe 3 is provided with pull bar 4, sliding block 5 is provided with pulling eye, pull bar 4 is buckled in the pulling eye of sliding block 5.
In the pulling eye of sliding block 5, leave cavity in the bottom of pull bar 4 terminations, like this, when top shoe moves down, but in the pull bar 4 indentation sliding blocks 5.
3 of pull bar 4 and top shoes can be used for regulating the distance of slide down interblock by being threaded.
When punching press, the bent axle of punch press promotes top shoe 3 through connecting rod 1 and moves down, and in the pulling eye of pull bar 4 indentation sliding blocks 5, top shoe 3 promotes sliding block 5, carries out stamping press.
When resetting, the bent axle of punch press moves on connecting rod 1 pulling top shoe 3, because gravity, slide block separates up and down, and pull bar 4 is pulled out.
Because the patrix of mould is contained on the sliding block 5, counterdie is contained on the workbench of support, and the stroke of sliding block 5 is the aperture of mould.
The stroke of top shoe 3 deducts the stroke of pull bar 4, i.e. the stroke ratio of the stroke of sliding block 5, thereby sliding block 5 has the little of punch press now, by regulating, can prevent that operator's hand from entering mould, has guaranteed the safety of using.
