The invention discloses an automobile side wall outer plate drawing die provided with an auxiliary drawing male die. The automobile side wall outer plate drawing die provided with the auxiliary drawing male die comprises an upper die holder, a lower die holder and a blank holder. The upper die holder is provided with a drawing female die. The lower die holder is correspondingly provided with a drawing male die matched with the drawing female die. The drawing male die is arranged inside the blank holder and connected with the blank holder in a sliding manner. The auxiliary drawing male die is arranged on the lower die holder. The auxiliary drawing male die is located between the drawing male die and the blank holder and connected with the blank holder in a sliding manner. The auxiliary drawing male die is opposite to the connection site of the automatic side wall outer plate, a back cover and a back air window. According to the automobile side wall outer plate drawing die provided with the auxiliary drawing male die, because the auxiliary drawing male die is arranged between the drawing male die and the blank holder, in the early period of drawing forming, the auxiliary drawing male die can allow plate materials to flow in, and the situation that the plate materials are drawn broken because the plate materials are excessively thin is avoided; and in the later period of drawing forming, the auxiliary drawing male die can prevent outside plate materials from flowing in and can also have the function of drawing the plate materials from the inner side to the outer side, and therefore deformation of the plate materials opposite to the connection site is more sufficient.

The invention discloses an oil paint coating method for an external identifier of a metro vehicle, which comprises the steps of blending oil paint and a curing agent according to a certain volume ratio; manufacturing a silk-screen template according to the content of the identifier, and fixing the silk-screen template at an external corresponding region of the vehicle; coating the blended oil paint on the silk-screen template, and performing the blade coating by a scratch board; and removing the silk-screen template, and drying the identifier under a room temperature. Due to the oil paint coating method, the external identifier of the metro vehicle is good in weather resistance, ultraviolet ray resistance, aging resistance and the like, so that the use durability of the external identifier of the metro vehicle can be guaranteed, the aging, the fading and the falling of the external identifier of the metro vehicle through wind blowing, raining and solarizing and the cleaning of vehiclecleaning liquid caused by lamination can be completely eradicated, the passenger safety can be guaranteed, and the metro vehicle can be conveniently overhauled. Meanwhile, due to the oil paint coating method of the external identifier of the metro vehicle, the quality of the metro vehicle is greatly improved.

The invention relates to a quantitative tissue mass incision and implantation device, comprising a rectangular outer thimble, a rectangular inner thimble, a rectangular locating core and a swivel knife; the rectangular locating core with sealed front face is movably and internally sleeved in the inner thimble, and the rectangular locating core and the inner thimble are movably and internally sleeved in the outer thimble together; the swivel knife is arranged in the thimble wall at the front end of the rectangular inner thimble; the swivel knife comprises a swivel knife head and a swivel knifehandle; the swivel knife head is fixedly connected on the swivel knife handle; the swivel knife handle is arranged in the side wall of the rectangular inner thimble in the axial direction and extendsbackward out of the side wall; the swivel knife head is arranged in the side wall of the rectangular inner thimble in the direction of end face; when the swivel knife rotates, the swivel knife head transversely incises a lumen end face of the rectangular inner thimble. By adopting the above technical proposal, a set of standard tumor mass incision and implantation devices is designed and manufactured, and in combination with the stipulated use method, serious defects in the process of manufacturing current models can be effectively evaded and standardization degrees of animal tumor formation models can be improved.

The present invention discloses detection method and detecting sensor for vehicle tire. The detecting sensor includes lining, detection circuit board on the lining with electrodes, electrically isolating layer on the detection circuit board and with hole in the position corresponding to the electrodes, elastic conducting layer on the electrically isolating layer, and elastic casing on the elastic conducting layer and fixed on the lining. When no vehicle passes, the electrodes are in off state, and during vehicle passing, the conducting layer is pressed to turn on the electrodes and some signal is output. The present invention has simple structure, and can detect tire number by means of several detection circuits. The present invention may operate in harsh condition and is accurate and durable.
