Detailed Description

The present invention will be further explained with reference to the accompanying drawings:

with reference to the accompanying drawings: the heat treatment device for quenching the electrical contact forming die comprises an electric cabinet 1, an oil liquid barrel 2 and a feeding track 3, wherein the electric cabinet 1 is provided with an electric heating wire 11, the electric heating wire 11 is positioned above the oil liquid barrel 2 and is provided with a placing sleeve 12, the length of the placing sleeve 12 is the same as that of the electrical contact forming die, the feeding track 3 is positioned at the feeding end of the placing sleeve 12, the feeding part of the feeding track is linearly arranged, the discharging part is obliquely arranged and is provided with a first channel 31, the first channel 31 is semicircular, a feeding hole 31-a and a discharging hole 31-b are formed in the feeding track 3, a material pushing part 4 is arranged at the feeding hole 31-a and used for pushing the electric contact forming die, and a buffering part 5 is arranged at the discharging hole 31-b and used for reducing the moving speed of the electric contact forming die before the electric contact forming die enters the placing sleeve 12. The feeding part of the feeding track is arranged linearly, the discharging part is arranged obliquely, and downward inertia force can be brought to the electrical contact forming die by utilizing the oblique gradient.

In order to ensure that the electrical contact forming die pushed each time can accurately fall into the placing sleeve 12, the transverse center of the first channel 31 and the transverse center of the placing sleeve 12 are the same center, and the whole volume of the placing sleeve 12 is larger than that of the electrical contact forming die, so that when the centers of the two are aligned, any part of the electrical contact forming die cannot be in contact with the placing sleeve 12, namely, the electrical contact forming die cannot enter into interference, and the electrical contact forming die has a falling action after entering, thereby ensuring that the electrical contact forming die can succeed in entering at each time.

For the pushing member 4, the pushing member 4 is mainly used for pushing the electrical contact forming mold to the placing sleeve 12, so that the electrical contact forming mold does not need to be manually placed, the probability that the hands of workers are in contact with the electrical heating wires can be effectively avoided, the pushing member 4 is provided with an executing part 41 and a pushing part 42, the executing part 41 is installed on the outer end face of the feeding track 3 at the position of the feeding hole 31-a, the pushing part 42 is placed in the first channel 31 and connected with the executing part 41, the executing part 41 provides power, namely the pushing part 42 moves along the track of the first channel 31, the pushing part 42 can prolong the pushing length, the pushing length can meet the condition that the electrical contact forming mold is separated from the first channel 31 and enters the placing sleeve 12, meanwhile, in order to avoid the situation that the pushing part 42 shakes due to a long-axis structure, the pushing part 42 is made into a cylindrical structure, and the radius of the pushing part is matched with the radius of the first channel 31, the outer wall of the pushing portion 42 can be attached to the inner wall of the first channel 31, so that the pushing portion 42 does not shake during pushing, and pushing quality can be improved.

Further perfection, the execution part 41 is a cylinder, the cylinder moves linearly, the execution force is strong, and the pushing mechanism is applicable to pushing structures, simple in structure and convenient to operate.

In order to ensure the success rate of pushing, a centrally arranged pin 42-a is fixed at the end of the pushing portion 42 not connected with the executing portion 41, because a cavity for forming the electrical contact is formed at the center of the electrical contact forming mold, the control of the electrical contact forming mold is more in place by virtue of the cavity, and the shake of the electrical contact forming mold in the pushing process can be reduced.

For the buffer member 5, considering that the working efficiency of the air cylinder is high, namely the pushing speed is high, and the middle part of the placing sleeve 12 is a through cavity, the arrangement is such that the feeding and the discharging can be realized, when the next electrical contact forming mold enters, the electrical contact forming mold which is heated can be ejected, so in order to prevent the electrical contact forming mold from being separated from the placing sleeve 12 due to the strong pushing force caused by the air cylinder because the inertia is too large in the placing sleeve 12, the buffer member 5 is added to slow down the moving speed of the electrical contact forming mold before entering the placing sleeve 12, thereby avoiding the separation of the electrical contact forming mold when entering the placing sleeve 12, the buffer member 5 is provided with a sliding part 51 and two dragging parts 52, the sliding part 51 is connected to the upper end of the feeding rail 3 in a sliding manner, the two dragging parts 52 are symmetrically distributed at the front end and the rear end of the sliding part 51 to reduce the pushing speed of the pushing part 42 and simultaneously realize the automatic resetting of the sliding part 51, when the pushing part 42 pushes the electrical contact forming die to a position close to the discharge port 31-b, the pushing part can be in contact with the sliding part 51, the sliding part 51 is limited in advancing stroke under the action of the two dragging parts 52, and the advancing speed of the pushing part 42 can be reduced under the influence of dragging force, so that the moving speed of the electrical contact forming die is reduced, and the automatic resetting characteristic can help the sliding part 51 to realize automatic resetting after sliding out, so that manual adjustment is not needed.

Further perfection, the upper end of the pushing part 42 is also fixed with a protrusion 42-b, and the protrusion 42-b is arranged to enable the pushing part 42 to drive the sliding part 51 to move.

In order to avoid the tilting of the electrical contact forming die due to the slope during discharging, the second channel 51-a is formed in the middle of the lower end of the sliding portion 51, the second channel 51-a is semi-circular and forms a complete circle after being spliced with the first channel 31, the electrical contact forming die generates sliding inertia during sliding, the electrical contact forming die generates upward tilting action after being separated from the pushing portion 42 under the action of the inertia, the action may cause that the electrical contact forming die cannot smoothly enter the placing sleeve 12, and therefore the upper limit of the electrical contact forming die is realized by forming the second channel 51-a at the lower end of the sliding portion 51.

In order to provide the automatic return effect to the pulling part 52, the pulling part 52 comprises a hydraulic rod 52-a and a return spring 52-b, the hydraulic rod 52-a is hinged at one end to the feeding track 3 and at the other end to the sliding part 51, the return spring 52-b is connected at one end to the connecting arm 52-a and at the other end to the feeding track 3, the two ends are hinged so that the hydraulic rod 52-a can adapt to the advance of the sliding part 51, i.e., without interfering with the movement of the slider 51, and the hydraulic rod 52-a, having a telescopic structure, can also accommodate the sliding of the slider 51, but also to stably confine the slide 51 in the feed rail 3, and the return spring 52-b is provided to return the slide 51 to the original position after the thrust of the slide is lost, the retraction of slide 51, i.e. the return of hydraulic rod 52-a to the initial state, is achieved with a self-resetting property of its own.

While the invention has been shown and described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the scope of the appended claims.
