[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 adjusting mechanism for a forming machine. The upper punch adjusting mechanism comprises a main driving mechanism allowing an upper punch to move up and down, and an auxiliary driving mechanism for adjusting the upper punch to enter a mold cavity in depth, wherein the auxiliary driving mechanism is externally arranged at an upper punch part. The upper punch adjusting mechanism provided by the invention has the advantages that: (1) the upper punch adjusting mechanism comprises the main driving mechanism and the auxiliary driving mechanism, the main driving mechanism coarsely adjusts the upper punch position, so that the upper punch reaches to a certain position; the auxiliary driving mechanism finely adjusts the upper punch position, so that the upper punch moves to a certain position, and such mode can achieve the accurate adjustment of upper punch strokes; (2) the displacement of up and down movement of the upper punch can be detected by an encoder, the upper punch can be accurately adjusted in place by the encoder, and the adjustment mode is simple and accurate; (3) through skillful combination of a telescopic mechanism, a worm and worm wheel mechanism and the like, the upper punch strokes can be accurately and quickly adjusted.
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...
