Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments, wherein the dimensional ratios in the drawings do not represent actual dimensional ratios, and are only used for representing relative positional relationships and connection relationships between components, and the components with the same names or the same reference numbers represent similar or identical structures and are only used for illustrative purposes.

The valve guide blanking transition device is indicated by reference numeral 1 in the attached drawings, and is abbreviated as the transition device 1 in the following description, the valve guide blanking transition device is actually used for conveying and collecting pressed blanks of valve guides for powder metallurgy, and the pressed blanks of the valve guides are abbreviated as valve guides W in the following description.

As shown in the schematic diagram of fig. 1, in the conventional production method, a feeding chute 7 is provided on a press of a valve guide W, and a receiving rail 9 driven by power is connected to a feeding opening 71 of the feeding chute 7 to convey the valve guide W from the forming press to an alignment machine. The blanking slideway 7 is arranged in a vertical plane in an inclined way, the angle between the blanking slideway 7 and the horizontal plane is usually 40-60 degrees, the valve guide pipe W is driven by the dead weight to fall to the blanking port 71, the blanking port 71 or the whole blanking slideway 7 generally moves back and forth along the direction shown by D in figure 1 according to the action time sequence regularity of the press, and the valve guide pipe W falls into the material receiving track 9 when the blanking port 71 moves to be relatively close to the inlet of the material receiving track 9. The receiving track 9 is generally horizontally arranged, a route is arranged according to layout requirements, the receiving track 9 drives the conveying valve guide pipe W through power, and the conveying device is common in production. However, in the actual production process, it is found that the valve guide W enters the alignment machine to detect more breakage and damage, which causes the alarm and even shutdown of the equipment, thereby affecting the starting rate of the equipment, and the yield of the produced products is also reduced, which increases the production cost. Through analysis and inspection, the damage of the valve guide pipe W is mainly determined to occur at the transition position of the blanking slide 7 and the material receiving track 9. Because the angle difference between the feeding slideway 7 and the material receiving track 9 reaches 40-60 degrees, the valve guide pipe W has large impact in the process of falling to the feeding port 71 and then entering the material receiving track 9, and the valve guide pipe W is formed by pressing powder, has poor structural adhesive force and is broken when encountering impact. To solve this problem, it is conceivable to reduce the inclination angle of the discharge chute 7, but this increases the falling distance, occupies a larger production area, and the discharge opening 71 is linked with the operation of the press, increases the inclination angle of the discharge chute 7, increases its own length, is not favorable to the stable operation in the linkage process, and may cause problems of increased vibration and delayed operation. Consequently, this application has designed the transition device 1 that sets up between unloading slide 7 and receipts material track 9 under the unchangeable prerequisite of the angle of maintaining unloading slide 7 to reduce the impact to valve guide W in the transition process, avoid because the fracture damage of the valve guide W that the impact force caused greatly.

Fig. 2 is a schematic installation diagram of the transition device 1 of the present application, the transition device 1 is installed below the feeding chute 7, the front surface of the transition device 1 is attached to the bottom surface of the feeding opening 71, the back surface of the transition device 1 is attached to the upper surface of the receiving track 9, and the position of the transition device 1 is fixed, and the additional required fasteners for fixing the transition device are not shown in the figure. The feed opening 71 is still arranged to move back and forth as shown in fig. 1, i.e. the feed opening 71 may remain in engagement with the upper surface of the support surface 11 of the transition device 1 when the transition device 1 is mounted and the feed opening 71 is moved. The transition slide ways 13 are arranged on the side surfaces, parallel to the supporting surface 11, of the outlet of the discharging opening 71, the number of the transition slide ways 13 can be set as required, and more specifically, the number of the transition slide ways can be increased or decreased according to the number of the slide ways of the discharging slide ways 7 and the receiving tracks 9. When the valve guide pipe W falls from the discharging slideway 7, the valve guide pipe W firstly slides onto the transition slideway 13 through the discharging opening 71, appropriately changes the falling direction and the falling speed, and then slides into the material receiving rail 9 through the transition device 1. The original one-time falling process is divided into two segmented falling processes, and the falling tail end of the valve guide pipe W is buffered.

Fig. 3 is a schematic view of embodiment 1 of the transition device 1, and the angle β between the transition chute 13 and the plane of the supporting surface 11 is 30 degrees, and is generally controlled within the range of 145 to 165 degrees. When preventing the angle and being too little, the inclination is too big, and the buffering effect is not enough, in order to avoid the angle too big simultaneously, and the buffering section is not only mild but also long for the example, leads to power not enough, takes place the putty. Because the transition slideway 13 actually extends into the inside of the receiving track 9, the flanges 131 arranged at the two sides of the transition slideway 13 are not necessary, but from the angle of forming and manufacturing, the cost for increasing the flanges is almost negligible, the flanges can be turned over by the excess material between the transition slideway 13 during punch forming, and simultaneously, the strength of the transition slideway 13 can be improved, so the flanges 131 can be optionally arranged.

Fig. 4 is a schematic view of an embodiment 2 of the transition device 1, wherein the transition chute 13 is arranged in a curve, the upper end of the transition chute is approximately tangent to the feed opening 71, the lower end of the transition chute is approximately tangent to the receiving track 9, the transition chute is approximately tangent here, and only two tracks at the joint are considered to have a basically consistent trend, so that the impact of track mutation on the valve guide W is reduced, but the transition chute is not completely tangent in actual production installation, and even if the tolerance is not considered, the angular distance between the two tracks is acceptable within 10 degrees of the tangent state.

The above description is only for the preferred embodiment of the present invention and is not intended to limit the scope of the present invention, and various modifications and improvements made to the technical solution of the present invention by those skilled in the art without departing from the spirit of the present invention should fall within the protection scope defined by the claims of the present invention.
