Embodiment 1

[0022] Such as figure 1 , figure 2 , image 3 and Figure 4 As shown, a closed-type gantry high-speed punching machine frame includes an upper body 1 as the main working part, a lubricating oil passage 2, an oil tank 8, a crankshaft seat 3, bolts 4 and a hard thickened flat washer 5. The bottom of the crankshaft seat 3 is a plane, positioned on the corresponding plane in the platform body 1, and fixed by the bolt 4 and the hard thickened flat washer 5. The lubricating oil channel 2 is distributed on the inner wall around the punch frame, and the upper part is connected to the inner wall of the punch frame. The top tank 9 communicates, and the bottom communicates with the fuel tank 8 .

[0023] Bore channels 10 are provided on both sides of the bottom of the top box 9 , connecting the top box 9 and the lubricating oil passage 2 .

[0024] The lubricating oil from each lubricating point of the crankshaft flows to the top box, flows to the lubricating oil passage 2 through t...

Abstract

The invention relates to a closed type portal high-speed punch press stand which comprises a table body (1) used as a main working part on the upper part, a lubricating oil channel (2), an oil tank (8), a crankshaft tilting fillet (3), a bolt (4) and a hard thickening flat washer (5), wherein the bottom of the crankshaft tilting fillet (3) is a plane and is positioned on a corresponding plane in the table body (1) and fixed through the bolt (4) and the hard thickening flat washer (5); the lubricating oil channel (2) is distributed on the inner wall on the periphery of the punch press stand, and the upper part of the lubricating oil channel (2) is communicated with a top box (9), while the lower part is communicated with the oil tank (8); both sides at the bottom of the top box (9) are provided with a hole channel (10) communicated with the top box (9) and the lubricating oil channel (2); the bolt (4) is a grade-12.9 high-strength bolt; and the hard thickening flat washer (5) is flat washer chamfered grade A with a hardness grade of HV300. The invention can solve the problems of large mounting difficulty of the crankshaft tilting fillet, high processing expense and device lubricating oil return in the prior art.

Description

technical field [0001] The invention belongs to the field of closed gantry presses, in particular to a closed gantry high-speed punch machine frame. Background technique [0002] In the closed gantry press, the mating surface of the crankshaft seat and the table body is generally a shaft-hole fit. This kind of fit has special requirements for the mounting holes of the two crankshaft seats during processing, such as concentricity, roundness, etc. The larger the model, the longer the distance between the two crankshaft mounting holes on the platform body, and the larger the diameter of the hole, so the processing difficulty is higher and the processing cost is more expensive. Especially for high-speed punching machines, due to the relatively high number of strokes per minute, the requirements for the installation hole of the crankshaft seat are higher, because the accuracy of this hole directly affects the accuracy and heat generation of high-speed punching machines. And the ...
