Description

A kind of lucite stretching clamp of self-tightening type
Technical field
The utility model relates to the lucite stretching clamp of a kind of stretching clamp, particularly a kind of self-tightening type.
Background technology
Macromolecule transparent material polymethyl methacrylate, is commonly called as lucite (methyl methacrylate) and is abbreviated as PMMA, and it needs to realize stretching aborning.The success or failure that stretching clamp stretches to lucite play critical effect.The effect of fixture is in the cooling procedure in drawing process and after stretching, all the time clamp the edge of lucite, this just requires fixture to have larger intensity, and lucite is had to enough clamping forces, and fixture will have the ability of cooling clamping part lucite simultaneously.
At present, the normal plunger type Cooling fixture being formed by cooling rod 1, connecting bolt 2, pull bar 3, clamp nut 4 and brace 5 adopting in lucite drawing process is processed, as shown in Figure 1, use this fixture, must on lucite 6, hole, because contacting of cooling rod 1 and hole on lucite is not tight, film-cooled heat is little, and only, lucite low by nut compressing, cooling effectiveness to be drawn into power lower.In order to improve cooling effectiveness, need to before water flowing is cooling, tighten for the second time fixture; Due to cooling, in drawing process, often make the hole lengthening deformation on lucite not, more difficult during dismounting fixture.Therefore, we are necessary existing lucite stretching clamp to make technological improvement.
Utility model content
The purpose of this utility model is in order to solve the deficiency of above-mentioned technology, to provide a kind of dismounting to change, the lucite stretching clamp to a kind of self-tightening type of clamping lucite good cooling results.
In order to achieve the above object, the lucite stretching clamp of a kind of self-tightening type that the utility model is designed, it is characterized in that it comprises a supporting fork, a pair of short swing arm, a connecting rod, an elastomeric element, a pair of long swing arm and two cooling blocks, wherein above-mentioned a pair of long swing arm is bell mouth shape and arranges, a short swing arm is fixed respectively in two ends of its enlarging, a cooling block is fixed respectively in two ends of its slot, the other end of two above-mentioned short swing arms is hinged together, and this hinged place fixed connecting rod, the both ends of above-mentioned supporting fork have been hinged on respectively the above-mentioned waist location that is two long swing arms that horn mouth arranges, elastomeric element in above-mentioned has been connected between the middle section and the bottom of connecting rod of above-mentioned supporting fork, and elastomeric element is all the time in tightening up shape, the upper end of above-mentioned connecting rod is connected with connecting bolt.
As further preferably, the elastomeric element in above-mentioned is the dish spring of one group of parallel arrangement.The advantages such as the dish spring adopting in this preferred version has long service life, and elastic restoring force is strong, can effectively promote service life of above-mentioned self-tightening type stretching clamp.
As further technological improvement, facilitate installing/dismounting between connecting bolt and connecting rod, the connecting rod in above-mentioned is Y-shaped, and a pair of yoke of its upper end is common connects a connecting bolt.
The lucite stretching clamp of a kind of self-tightening type provided by the utility model, screen resilience by elastomeric element in concrete use produces pre-beginning thrust, in drawing process, the power of connecting rod passes to short swing arm, utilizing lever principle take and supporting fork is fulcrum, by long swing arm, power is delivered to cooling block and compresses lucite, adopt this fixture not need again in punching on glass, do not need to carry out secondary clamping, easy accessibility, thereby improved working condition, shortened service working time, promoted operating efficiency.
