Description
Technical field
The present invention is relevant with the employed facility of plastics plate combination processing, knows clearly it, refers to a kind of door board multi-point synchronous hot riveting machine especially, and it can carry out rivet hot cooperation industry synchronously to a plurality of riveted points of door-plate, for improving rivet hot cooperation industry efficient.
Background technology
Most automobile door leaf, part is provided with the door-plate that utilizes plastic shaping more in car, these Plastic door planks often need to carry out the rivet hot cooperation already when the processing assembling so that this door-plate must with plane materiel such as cladding, cloth or other parts as: Door Armrest combines.
See also Fig. 1, Fig. 2, if plastic plate rivet hot cooperation owner is when plastic plate 1 moulding, promptly put moulding tubulose ailhead 2 in advance in predetermined riveted, and the nail hole 4 that cooperates with it of the part 3 that makes this ailhead 2 be set in desire installing combination, then, utilize mechanical arm that electric heating die head 5 is shifted to this ailhead 2, and energising makes this die head 5 intensification heatings, utilize 2 heating of 5 pairs of these ailheads of electric heating die head, make this ailhead 2 fusions, and utilize the shape of this electric heating die head 5, make this ailhead 2 extend out distortion, these die head 5 outage coolings make this ailhead 2 typings at last, and this die head 5 can be removed and finish rivet hot cooperation industry.
See also Fig. 3, known electric heating die head 5 mainly is made of a heating head 501, an electric heating piece 502, a shell 503, an insulating barrier 504 and two conductive plates 505, wherein, these heating head 501 1 ends form riveting die 5012, its other end axle is gone in this shell 503, this electric heating piece 502 is located on this heating head 501 peripheries, and one end axle is gone in this shell 503, and join with this conductive plate 505, to pass through this electric heating piece 502 by these conductive plate 505 guiding electric currents, according to making this electric heating piece 502 produce heat energy, impel this heating head 501 to heat up and generate heat the heat supply riveting job; These shell 503 inner filling resin materials constitute this insulating barrier 504, improve security according to this.
If the rivet hot cooperation owner of known automobile-used door panel utilizes mechanical arm to carry out, it is that the electric heating die head is installed in mechanical arm, utilize program setting to make the mechanical arm band draw the electric heating die head and move to the location, automobile-used door panel is carried out the hot riveting operation, though these rivet hot cooperation industries can critically be controlled mechanical arm by microcomputer program, a but because rivet hot cooperation of the every execution of mechanical arm industry, only can finish a riveted point, and automobile-used door panel is when making assembling, often need to finish tens, even the riveting job of dozens of riveted point nearly, known utilize mechanical arm to carry out the rivet hot cooperation already institute's time-consuming is long, be difficult to satisfy the demand of volume production operation.
Moreover, known electric heating die head 5 utilizes these electric heating piece 502 generation heat energy to impel this heating head 501 intensification heatings, close plastics part by metapyretic these heating head 501 rivet hots again, thermal energy transfer process between this electric heating piece 502 and this heating head 501, be difficult to avoid taking place the dissipation of heat energy consume, the utilization rate that is unfavorable for electric energy, and at these 502 energising initial stages of electric heating piece, can't impel this heating head 501 to be warming up to operating temperature at once, after rivet hot is closed, this heating head 501 is difficult to the cooling of lowering the temperature apace again, influences follow-up demould time, so influence operating efficiency.
