Abstract
The present invention provides a means to enhance the efficacy of material straightening operations for the automotive collision repair industry. In particular, the present invention provides a means to straighten material with reduced stress provided and sustained by in-line push or pull devices while providing gradual removal of dents, kinks, and other distortions in metals used in automotive construction. Through the use of rapid short travel bursts of push or pull force as required, the present invention reduces secondary damage of the material under work and repair hardware that is generally attributable to the excessive application of force in the prior art. Further, a controlled means of straightening is provided such that the operator may correct alignment and force application during the course of repair and as required while enhancing the safety and efficacy of repair.
Description
COLLISION REPAIR PUSH AND PULL ENHANCEMENT METHOD AND
APPARATUS
BACKGROUND OF THE INVENTION
1. Field of the Invention The present invention generally relates to automotive collision repair technologies and methods providing damaged material straightening means. Specifically, the present invention relates to the methods and apparatus employed to straighten steel that has been damaged under the stress of collision where dents, kinks, and other distortions are exhibited. The application of the present invention during material straightening is appropriate where reduced secondary damage, increased efficiency, and enhanced safety are desired.
APPARATUS
BACKGROUND OF THE INVENTION
1. Field of the Invention The present invention generally relates to automotive collision repair technologies and methods providing damaged material straightening means. Specifically, the present invention relates to the methods and apparatus employed to straighten steel that has been damaged under the stress of collision where dents, kinks, and other distortions are exhibited. The application of the present invention during material straightening is appropriate where reduced secondary damage, increased efficiency, and enhanced safety are desired.
2. Description of the Prior Art Prior art embodiments which require the operator to apply pushing or pulling forces at the site of the work in order to straighten kinked, bent, misaligned, or distorted steel automotive body and frame components often rely on single vector forces up to and occasionally in excess of 60KN provided by a powered pushing or pulling device connected by chain. In addition to the extreme forces applied in certain applications, such hard pushes or pulls often result in secondary damage arising from over-stressing of thinner gauge steel common to the construction of modem automobiles. Secondary damage in such scenarios can further be characterized as metal thinning, metal tearing, bending along undesired vectors, and distortion of component geometry. The application of excessive pushing or pulling forces in such collision repair environments can jeopardize operator safety in the event of catastrophic failure of either components under work or powered components. Efficiency is compromised in the high incidence of secondary damage and the inability to sufficiently control the overall impact of applied forces.
SUMMARY OF THE INVENTION
The present invention allows the operator to place a push and pull enhancement apparatus in line with pushing or pulling forces for the purposes of straightening dented, kinked, or otherwise distorted steel in the course of collision repair. The operation of the push and pull enhancement apparatus provides rapid short travel bursts of increased pushing or pulling force in order to reduce in-line push or pull force requirements to well below device limits and to provide a more gradual and controlled straightening of material under work. The gradual and controlled straightening of material by these means reduces the likelihood of secondary damage and increases the efficiency and safety of the straightening process. The push and pull enhancement allows the operator to use a conventional air hammer and bit attachment to provide stroke means to achieve the rapid short travel bursts of increased pulling force thereby providing ease of application and a method generally free of the deficiencies of the prior art.
