In order to provide a larger upper limit of pressure, the lever type pressure mechanism comprises four vertical mounting upright posts 8 arranged on the top surface of the top frame 3 in a matrix shape, and a plurality of layers of lever type pressure components uniformly sleeved on the mounting upright posts 8 along the vertical direction. Each layer of lever type pressure component has a pressure amplification effect, and the pressure total upper limit is lifted by assembling the plurality of layers of lever type pressure components.
The lever type pressure component comprises a square base plate 12, wherein four corners of the base plate 12 are respectively provided with a vertical sleeve 9 matched with the mounting upright posts 8, and the four vertical sleeves 9 are sleeved on the four mounting upright posts 8 through the sleeves 9.

On the basis, in order to further improve the stability, a rubber gasket 26 is arranged between the sleeves 9 of two adjacent layers of the lever type pressure components, and the increase of the rubber gasket 26 can also prevent the sleeves 9 from being mutually worn. The multiple sleeves 9 position the substrate 12 together, so that the substrate 12 is ensured not to shake, and the stability is good.
The lever type pressure component further comprises a transmission cross rod 10 and a transmission vertical rod 11, a cross beam 13 is arranged between the front side edge and the rear side edge of the base plate 12, and the transmission vertical rod 11 is installed on the cross beam 13 and can move in the up-and-down direction. The power is transmitted through the cooperation of the transmission cross rod 10 and the transmission vertical rod 11. As shown in fig. 2, a first hinge seat 14 is further disposed on one of the left and right sides of the base plate 12, one end of the transmission cross bar 10 is hinged to the first hinge seat 14, and the middle section of the transmission cross bar 10 is in transmission connection with the upper end of the transmission upright 11. Of course, a torsion spring for driving the transmission cross bar 10 to return upward may be further provided in the first hinge seat 14 in consideration of the return of the transmission cross bar 10.
As shown in fig. 1, for the convenience of operation, the free end of the transmission cross bar 10 of the lever type pressure assembly located at the uppermost layer is provided with a section of a handle section 15 in an extension. The lower end of a transmission upright rod 11 of the lever type pressure component positioned at the lowermost layer is in transmission connection with the punch 5. The hinged positions of the transmission cross bars 10 of the adjacent two layers of lever type pressure components on the base plate 12 are opposite, and the lower ends of the transmission upright bars 11 of the lever type pressure components on the upper layer are in transmission connection with the free ends of the transmission cross bars 10 of the lever type pressure components on the lower layer.

In the using process of the invention, a workpiece is placed on the lower die 7, the handle section 15 is pulled down by hands, the transmission cross rod 10 and the transmission upright rod 11 sequentially transmit power downwards, and the overall pressure can be greatly improved due to repeated pressurization of a plurality of lever-type structures in the power transmission process, and finally the punch 5 and the upper die 6 on the punch are driven to move downwards to be matched with the lower die 7, so that the processing of the workpiece is realized. Compared with the traditional mode, the invention can match different numbers of lever type pressure components according to the actual situation, theoretically, the more the number of the lever type pressure components is, the larger the upper limit of the pressure which can be output by the lever type pressure components is, and the invention is very suitable for high-strength stamping. Meanwhile, the traditional mode that the length of the handle section 15 is increased and the length of the sleeve is increased on the handle section 15 is eliminated, so that the whole structure of the equipment is more compact and reasonable.
In practical design, the most conventional transmission upright rod 11 is a vertical rod, two ends of the vertical rod are directly contacted with the transmission cross rod 10 to realize transmission, grooves can be arranged at the upper end and the lower end of the vertical rod to facilitate the contact of the vertical rod and the transmission cross rod 10, and in this case, the transmission connection of the vertical rod and the punch 5 can be realized by directly contacting the lower end of the vertical rod with the upper end of the punch 5.
