[0003] The existing upstroke adjustment method generally adjusts the upstroke stroke on the basis of using the existing driving mechanism. The error of this adjustment method is relatively large, and this method cannot meet the processing requirements for some products that require high processing accuracy; Or now adjust the upstroke stroke by setting gaskets in the mold, etc. This method has a better effect, but it is more complicated, time-consuming and laborious, and affects the processing efficiency

Embodiment Construction
[0015] The invention includes a main driving mechanism for moving the upper punch up and down and an auxiliary driving mechanism for adjusting the depth of the upper punch entering the mold cavity, and the auxiliary driving mechanism is placed outside the upper punch.
[0016] The auxiliary driving mechanism includes a motor 1, which is connected to a telescopic mechanism through a transmission mechanism, and the telescopic mechanism drives the upper punch adjustment ball screw 11 to move up and down through the worm 6 and the worm wheel 10, and then drives the upper punch to move through the upper sliding column 12, so The motor 1 is provided with an encoder 2.
[0017] The transmission mechanism includes a bevel gear pair 3 and a transmission shaft 4 , and the transmission shaft 4 transmits power to a worm 6 through a telescopic universal joint 5 .
[0018] The main driving mechanism: includes a connecting rod 9 connected with the upper punch adjustment ball screw 11 , the i...

The invention relates to an upper punch adjustment mechanism of a molding machine. It includes a main driving mechanism for moving the upper punch up and down and an auxiliary driving mechanism for adjusting the depth of the upper punch entering the mold cavity, and the auxiliary driving mechanism is set outside the upper punch. The advantages of the present invention are: 1) The present invention includes a main drive mechanism and an auxiliary drive mechanism, the main drive mechanism roughly adjusts the position of the upper punch to make the upper punch reach a certain position; then it is finely adjusted by the auxiliary drive mechanism, Make the upper punch move to a certain position, this way can realize the accurate adjustment of the upper punch stroke; 2) The present invention detects the displacement of the upper punch through the encoder, and the operator can accurately adjust the upper punch only through the encoder The adjustment is in place, and the adjustment method is simple and accurate; 3) The present invention adopts the telescopic mechanism and the worm gear mechanism, and through the ingenious cooperation of each mechanism, the fine adjustment of the upward stroke of the present invention can achieve the effect of precise and fast adjustment.
Description
technical field [0001] The invention relates to an upper punch adjustment mechanism of a forming machine, which is applied in the technical field of powder metallurgy product parts pressing and forming. Background technique [0002] When the powder metallurgy forming machine is processing powder products of different types and thicknesses, the upstroke stroke needs to be adjusted according to the difference of the processed products. [0003] The existing upstroke adjustment method generally adjusts the upstroke stroke on the basis of using the existing driving mechanism. The error of this adjustment method is relatively large, and this method cannot meet the processing requirements for some products that require high processing accuracy; Or now adjust the upstroke stroke by setting gaskets in the mold, etc. This method has a better effect, but it is more complicated, time-consuming and laborious, and affects the processing efficiency. Contents of the invention [0004] T...
