Description

A kind of clamping resetting means

Technical field

This utility model relates to clamping resetting structure design field, espespecially a kind of clamping resetting means.

Background technology

At present level type binding clasp is resetted and is realized by back-moving spring and steel ball, its detailed structure view as it is shown in figure 1, Clamping reseting procedure explanation: in the clamping hydraulic fluid port on body 1 after injection pressure oil, first piston bar 4 is ejected, and then promotes Lever 2 rotates around bearing pin 3, and lever is tilted to the right and clamp module A, completes pinching action.As in figure 2 it is shown, answering in body 1 In the hydraulic fluid port of position after injection pressure oil, first piston bar 4 is return in situ, back-moving spring 10 and steel ball 9 jack-up lever 2, completes to reset Action.

Above-mentioned level type binding clasp is traditional Die clamps, and general work frequency is clamping and release number of times every day 25 times Hereinafter, traditional spring reset type binding clasp can meet the use requirement of this operating mode, and its service life is more than 5 years.But Being at special operation condition, this binding clasp is then difficult to meet requirement, and such as, the fluted disc binding clasp of injection machine needs every day and work 16 little Time, work and operating frequency are to work more than 5 times for one minute continuously per hour, and this spring reset binding clasp can be in real work During following two problem defect occurs:

(1) spring life is limited.Altofrequency, use binding clasp for a long time, may result in spring in the short period of time Lost efficacy.In the case of spring failure, lever can not complete reset, will with mould in FIG shown in contact point B at the moment It is in contact shape.Under actual working state, some mould is interim action, and ratio is if desired for rotation.In such situation Under, it is impossible to the lever of reset will rub with the mould rotated, and even more serious result is the interference that collides, the most logical Cross replacing spring and be just avoided that this situation occurs.

(2) body distortion is impaired.Altofrequency, binding clasp, the bearing pin 3 that hardness is higher is used to cause body 1 for a long time Raw plastic deformation, as it is shown on figure 3, body deforms at contact surface C, it addition, contacting between bearing pin with body also can be led Causing the pin shaft hole D serious wear shown in Fig. 3, the body 1 that lever 2 is deformed extrudes, and makes the restoring force of spring be not enough to gram The frictional force that clothes extruding therebetween causes, thus cause lever 2 can not normally complete homing action, when the interference that collides Time, only relying on replacing spring and can not meet production and application requirement, staff must change binding clasp again, and this is eventually Affecting client's manufacturing schedule, the maintenance cost that also can increase manufacturing facilities causes economic loss.

Therefore, the applicant is devoted to provide a kind of clamping resetting means, and it is when altofrequency, long-time use Service life is longer.
