Detailed Description

In order to better understand the technical solutions of the present invention for those skilled in the art, the following preferred embodiments of the present invention are described in conjunction with the specific examples, but it should be understood that these descriptions are only for the purpose of further explaining the features and advantages of the present invention, and are not intended to limit the patent requirements of the present invention. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The invention will be further described with reference to the accompanying drawings and preferred embodiments.

Example 1

Referring to fig. 1 and 2, the automobile fender hot stamping tool that this embodiment relates to has the frock fixing base 2 of profile modeling mounting face 1 including the top, set up the main negative pressure air flue 3 that extends about being the level in the frock fixing base 2, main negative pressure air flue 3's one end is equipped with piston cavity 4, the other end that is linked together rather than inside and is equipped with the balanced air flue 5 that is linked together rather than inside, and balanced air flue 5 also is the level and controls the extension, balanced air flue 5 is linked together dorsad main negative pressure air flue 3's one end and the external world, sliding connection has piston 6 in piston cavity 4, is equipped with on piston 6 and stretches out piston cavity 4's piston rod 7, it has concatenated the valve cavity 8 of seting up in frock fixing base 2 to balance air flue 5, and sliding connection has the valve plate 9 who makes perpendicular up-and-down motion in valve cavity 8, and the bottom of valve plate 9 is equipped with elastomer 10, and the one end of elastomer 10 supports valve cavity 8, the other end support valve plate 11, the top of valve plate 11 is equipped with connecting rod 12 of sliding connection on frock fixing base 2, and connecting rod 12 the one end is connected valve plate 9, the other end stretch out frock fixing base 2 and is equipped with press ball 13, set up on the one end of matching, set up the perpendicular negative pressure air flue 3 and is equipped with the negative pressure air flue 15 that the perpendicular mounting face is linked together about the frock mounting face that extends.

Further, a linear reciprocating mechanism (not shown in the figure) for controlling the piston rod 7 to move close to or far away from the main negative pressure air passage is arranged on the piston rod; the linear reciprocating mechanism is a push rod cylinder.

Further, the elastic body 10 is a compression spring.

In this embodiment, first, the elastic body 10 (i.e., the compression spring) is in the expanded state, the valve plate 9 is lifted, the air release hole 14 is misaligned with the balance air duct 5, and the balance air duct 5 is blocked and is not communicated with the outside. At this moment, the back of the automobile fender is firstly attached to the profiling attachment surface 1 of the tool fixing seat 2, so that the back of the automobile fender shields and blocks all the branch negative pressure air passages 15, and then the linear reciprocating motion mechanism (namely the push rod cylinder) is operated to enable the piston rod 7 and the upper piston 6 to move away from the main negative pressure air passage 3, so that a negative pressure source is formed inside the main negative pressure air passage 3, and the branch negative pressure air passage 15 communicated with the main negative pressure air passage 3 also forms a negative pressure source through air flow conduction, so that the automobile fender is adsorbed and clamped on the profiling attachment surface 1 of the tool fixing seat 2, and clamping is completed.

When the automobile fender subjected to the hot stamping process needs to be taken down from the profiling attachment surface 1 of the tool fixing seat 2, the pressing ball 13 can be pressed down, so that the connecting rod 12 and the valve plate 11 move downwards in the valve cavity 8, the elastic body 10 (namely a compression spring) is compressed until the air leakage hole 14 is communicated with the balance air passage 5, the balance air passage 5 is communicated with the outside, the negative pressure in the branch negative pressure air passage 15 and the main negative pressure air passage 3 is reduced to 0, and the automobile fender subjected to the hot stamping process can be easily taken down from the profiling attachment surface 1 of the tool fixing seat 2; and then resetting the linear reciprocating mechanism.

When the automobile fender subjected to the hot stamping process needs to be taken down from the profiling attachment surface 1 of the tool fixing seat 2, the linear reciprocating mechanism can be directly reset, so that the linear reciprocating mechanism drives the piston rod 7 and the upper piston 6 to move in the direction close to the main negative pressure air passage 3, a positive pressure source is formed inside the main negative pressure air passage 3, and a positive pressure source is formed inside the branch negative pressure air passage 15 communicated with the main negative pressure air passage 3 through air flow conduction, so that the automobile fender subjected to the hot stamping process can be easily taken down from the profiling attachment surface 1 of the tool fixing seat 2.

Example 2

Referring to fig. 1 to 4, in the automobile fender panel hot stamping tool according to the embodiment, on the basis of embodiment 1, an installation counter bore 16 formed in the profiling attachment surface 1 is further formed in the sub-negative pressure air passage 15, and a non-standard seal ring 17 with a top protruding out of the profiling attachment surface 1 is embedded in the installation counter bore 16.

Further, the non-standard sealing ring 17 is composed of a circular sealing base 171 and a sealing pipe 172 arranged on the sealing base 171, the outer diameter of the sealing pipe 172 is smaller than that of the sealing base 171, and a telescopic pipe 173 is connected to the sealing pipe 172 in series.

In this embodiment, the opening of the sealing tube 172 of the non-standard sealing ring 17 is pressed by the fender to move the opening downward, and the telescopic tube 173 deforms, so that a close fitting effect is formed between the non-standard sealing ring 17 and the fender, and a better adsorption clamping effect is achieved.

Wherein the deformation amount of the extension tube 173 can be placed in the mounting counterbore 16 by setting the outer diameter of the sealing tube 172 to be smaller than the outer diameter of the sealing base 171.

The utility model relates to a fender hot stamping frock installs on rather than identical profile modeling installation face through the fender cooperation to the negative pressure by the formation in the air flue makes fender adsorbed the clamping on the frock fixing base, avoids the edge centre gripping and makes and expose outside smooth surface impaired, has played quick clamping's effect, and overall function is perfect, and the practicality is strong.
