Abstract
The utility model relates to a mechanism of the functions of buffering, vibration reduction, and safety for a press, which aims at overcoming the problem of large vibration in the press existing in the prior art. The utility model is characterized in that a safety block 6 is arranged in a slide block 7 of a press instead of the collapsing block in the prior art, and the upper part of a ball-head press plate 4 of a press is provided with an elastic ring 3 which is exerted with pretightening force and a press plate 2. When the press is operated normally, a rubber block 10 in the safety block is compressed in a sealed containing frame 11, and makes buffering and dissipating effects on the vibration of the press with the elastic ring 3. When overload exists in the press, the side wall of the containing frame is cracked, displacement is generated between a connecting rod 1 and the slide block 7, so that the working stroke of the press is staggered, playing a function of safety. The utility model has the advantages that the structure is compact; the original structure of the appliance is not changed; the utility model has good buffering and noise lowering effects on vibration and noise generated under the normally operated state of the press; at the same time, the utility model has a safety function under the abnormally operated state of the press with overload.
Description
(1) technical field under:
The utility model relates to the press field, is a kind of buffer shock-absorbing and insurance institution of forcing press.
(2) background technology:
Forcing press is widely used a kind of press in the Metal Forming industry, the vibration and noise problem that forcing press produces is puzzlement engineers and technicians technical barriers for many years, it not only influences normal use, the reduction product quality of equipment, but also the physical and mental health that jeopardizes the site operation personnel.In order to address this problem, more is to adopt the fluid pressure type buffer unit and use shock absorber, and they can both play certain mitigation to the vibration of forcing press, but these oscillation damping methods, the vibration root of fundamentally not touching forcing press.The hydraulic bjuffer complex structure, debugging inconvenience also need increase many optional equipments such as oil pump, pipeline, invests very big.Hydraulic bjuffer is placed between workbench and the slide block, has not only increased the extra load of forcing press, also occupies operator's the useful space.The shock absorber that is installed under the press frame only has the better damping effect to the vibration of certain several frequency, its installation and change inconveniently, and entire machine is elevated, and easily causes rocking of machine top, and is unfavorable to producing.
(3) summary of the invention:
For overcoming the problem that exists in the existing forcing press noise reduction technology, the utility model provides a kind of buffer shock-absorbing and insurance institution of forcing press.
To achieve these goals, the utility model will be formed safety block after will being enclosed in the appearance frame by briquetting, block rubber, place press ram, to replace original breaker in the press ram; Install elastic ring and pressing plate additional on press ball pressing plate top, fastening back also applies pretightning force, makes bulb pressing plate and ball cup tightly hold the pressure bulb from upper and lower surface, alleviates the vibration that produces in the slide block movement process by elastic ring and safety block.
The utility model does not influence forcing press nominal operational forces and operating efficiency, and during less than overloading load, block rubber is compressed in the appearance frame of sealing in the suffered load of forcing press, and with elastic ring, buffering and dissipation effect is played in the vibration of forcing press; When forcing press transships, hold the frame sidewall by the block rubber spalling under the pressured state, the block rubber that holds in the frame overflows in the space that holds the frame sidewall, thus the impulse stroke of the forcing press that staggers, and between connecting rod and slide block, produce displacement, thus play safety effect.
The utility model compact conformation does not change the original structure of equipment, and the vibration and noise that produces under the forcing press normal operating conditions is had good buffering noise reduction effect, has insurance function again simultaneously under forcing press overload abnormal operating state.
(4) description of drawings:
Accompanying drawing 1 is a forcing press buffering insurance institution structural representation.
Accompanying drawing 2 is safety block structural representations.
(5) specific embodiment:
The forcing press buffering insurance institution of present embodiment is an example with J23-63 type forcing press, comprises that pressing plate 2, elastic ring 3 and safety block 6 constitute.
Briquetting 9, polyurethane rubber piece 10 are enclosed in composition safety blocks 6 in the appearance frame 11, and safety block 6 is placed press ram 7, replace breaker of the prior art.Wherein: briquetting 9 circular slab for making with No. 45 steel, its external diameter equals to hold the internal diameter of frame 11; Hold frame 11 for the thin wall circular shape foundry goods of base plate is arranged, the base plate external diameter is greater than the external diameter of annulus; Block rubber 10 usefulness polyurethane rubbers are made, and also are circular cylinder, and its external diameter equals to hold the internal diameter of frame 11, and height is less than the height that holds frame 11.
According to the physical dimension of forcing press, pressing plate 2 and elastic ring 3 are designed to annular, and its internal diameter is advisable can be inserted in connecting rod 1; Pressing plate 2 materials are No. 45 steel, and elastic ring 3 materials are the polyurethane rubber of hardness HS80A.
During assembling:
1. assemble safety block 6: polyurethane rubber piece 10 is contained in holds in the frame 11, then briquetting 9 placed in the appearance frame 11, on the polyurethane rubber piece 10, make polyurethane rubber piece 10 bear the effect of triaxial pressure in working order down.Briquetting 9 and holding between the frame 11 for movingly.
2. safety block 6 is placed under the slide block 7 pressure bulbs;
3. pressing plate 2, elastic ring 3 are sleeved on the pressure ball head connecting rod 1, elastic ring 3 is contained under the pressing plate 2, on the bulb pressing plate 4, by screw 8 fastening after, and apply pretightning force, tightly hold the pressure bulb of connecting rod 1 by upper and lower faces to guarantee bulb pressing plate 4 and ball cup 5.
The utility model is after having taked above technology, and vibration downward in the slide block movement is mainly by elastic ring 3 bufferings, and the vibration that slide block makes progress by safety block 6 bufferings, makes whole buffer gear when transmitting operating pressure, has the buffering insurance function.Simultaneously, according to design strength, when forcing press transships, hold frame 11 sidewalls by polyurethane rubber piece 10 spallings under the pressured state, the polyurethane rubber piece 10 that holds in the frame 11 overflows in the space that holds frame 11 sidewalls, thereby the impulse stroke of the forcing press that staggers, and in connecting rod 1 and 7 generations of slide block displacement, thereby play safety effect.And when forcing press bore proper working load, polyurethane rubber piece 10 was compressed in the appearance frame 11 of sealing, and with elastic ring 3, buffering and dissipation effect was played in the vibration of forcing press.
