Abstract
The utility model relates to a looseness-proof structure for a buffering cylinder of a frame single-action stretching press, which comprises the buffering cylinder, a buffering cylinder fixing sleeve and a locking nut. A cylinder body of the buffering cylinder is embedded in an upper beam from the upper end surface of the upper beam, the lower end surface of the cylinder body of the buffering cylinder is connected with the buffering cylinder fixing sleeve, the fixed lower portion of the buffering cylinder extends out of the lower end surface of the upper beam, and a portion, which extends out of the upper beam, of the buffering cylinder fixing sleeve is connected with the locking nut clinging to the lower end surface of the upper beam in a threaded manner. The looseness-proof structure has the advantages that a limiting groove is milled on a side wall of the lower end of the buffering cylinder fixing sleeve, the lower end surface of the upper beam on one side of the locking nut is welded with a fixing plate, the fixing plate is connected with a limiting plate via a bolt, and an end of the limiting plate is embedded in the limiting groove. As the end of the limiting plate is embedded in the limiting groove of the buffering cylinder fixing sleeve, rotation of the buffering cylinder fixing sleeve is avoided. When the buffering cylinder needs to be detached, the limiting plate is detached from the fixing plate, and the buffering cylinder can be detached and maintained conveniently.
Description
Technical field
The utility model relates to a kind of framework single action stretching press, particularly a kind of framework single action stretching press cushion dashpot anti-loose structure.
Background technology
Framework single action stretching press frame single action stretching press is widely used in processing such as the reverse-drawing, bending, moulding, stamping and blanking, flange of workpiece, and there is impulsive force in its slide block when quick descending stamping-out, be prone to cause noise and vibrations.The impulsive force that framework single action stretching press cushion dashpot is used to slow down slide block; It is installed in the last time of putting the beams in place; The cushion dashpot cylinder body embeds in the upper beam from the upper beam upper surface; Cushion dashpot cylinder body lower surface connects stretches out the cushion dashpot fixed cover of upper beam lower surface, is threaded on the cushion dashpot fixed cover and is close to the locknut of upper beam lower surface.The shortcoming of this kind structure is: cushion dashpot is when work, and there is the tendency of rotating in the cushion dashpot cylinder body, and is prone to drive the cushion dashpot fixed cover and rotates, and causes the loosening of cushion dashpot.Directly, then be unfavorable for dismounting, the maintenance of cushion dashpot with the fixed cover and the welding of putting the beams in place.
Summary of the invention
The technical problem that the utility model will solve provides a kind of framework single action stretching press cushion dashpot anti-loose structure, can avoid cushion dashpot loosening, and demolition and maintenance is convenient.
For solving the problems of the technologies described above; The technical scheme of the utility model is: a kind of framework single action stretching press cushion dashpot anti-loose structure; Comprise cushion dashpot, cushion dashpot fixed cover and locknut; Said cushion dashpot cylinder body embeds in the upper beam from the upper beam upper surface, and cushion dashpot cylinder body lower surface connects the cushion dashpot fixed cover, and the upper beam lower surface is stretched out in the fixing bottom of said cushion dashpot; The part that said cushion dashpot fixed cover stretches out upper beam is threaded and is close to the locknut of upper beam lower surface, and its innovative point is: the lower end sidewall of said cushion dashpot fixed cover is milled with stopper slot; Be welded with fixed head on the upper beam lower surface of said locknut one side, be connected with a limiting plate through bolt on the said fixed head, the end of said limiting plate embeds in the stopper slot.
The advantage of the utility model is: the stopper slot that utilizes the end embedding cushion dashpot fixed cover of limiting plate; Avoid the rotation of cushion dashpot fixed cover; And when needing the dismounting cushion dashpot, get final product from fixed head dismounting lower limiting board, be convenient to cushion dashpot is dismantled, safeguarded.
Description of drawings
Fig. 1 is the utility model middle frame single action stretching press cushion dashpot anti-loose structure sketch map.
The specific embodiment
As shown in Figure 1, comprise cushion dashpot 1, cushion dashpot fixed cover 2, locknut 3, fixed head 4, limiting plate 5.
Above-mentioned cushion dashpot 1 cylinder body embeds in the upper beam 6 from 6 upper surfaces of putting the beams in place; Cushion dashpot 1 cylinder body lower surface connects cushion dashpot fixed cover 2; 6 lower surfaces of putting the beams in place are stretched out in the bottom of this cushion dashpot fixed cover 2; The part that cushion dashpot fixed cover 2 stretches out upper beam is threaded and is close to the locknut 3 of 6 lower surfaces of putting the beams in place, thereby realizes the fixing of cushion dashpot 1 cylinder body.
Sidewall is milled with stopper slot in the lower end of cushion dashpot fixed cover 2; On upper beam 6 lower surfaces of locknut 3 one sides, be welded with fixed head 4; Auger shell pit on this fixed head 4 is connected with a limiting plate 5 through bolt on the fixed head 4, and the end of this limiting plate 5 embeds in the stopper slot of cushion dashpot fixed cover 2.Thereby avoid the rotation of cushion dashpot fixed cover 2, and when needing dismounting cushion dashpot 1, get final product, be convenient to cushion dashpot 1 is dismantled, safeguarded from fixed head 4 dismounting lower limiting boards 5.
Claims (1)
