Abstract

The utility model relates to a non-swing type roller compaction machine, which comprises a roller compaction head structure and a working table structure. The utility model is characterized in that the lower part of the roller compaction head is connected with a cone-shaped upper mould, and a large thrust bearing is arranged at both sides of an upper roller compaction head shaft and below a lower beam; an arc component is arranged below an upper beam, and a locking device is arranged at both sides; the roller compaction head shaft forms a gamma angle with a main shaft, and the gamma angle is 0 DEG-15 DEG; the working table is supported by a large size bearing and is connected with a lower cross beam; a spline coupling sleeve on a transmission shaft of the working table is connected with a hydraulic driving device. The operation of the utility model is easy to be realized, the roller compaction head just rotates about the shaft line of itself without fluctuation or alternating eccentric load to a machine frame so that the machine frame has the advantages of stable stress and high rigidity. The utility model has the advantages of little energy consumption and low cost.

Description

Non-swing type rivet bucker

The utility model relates to the non-swing type rivet bucker in a kind of press.

Conventional Forging Technology often disposable integral is shaped, and promptly the forging hammer vertical direction on workpiece, to the processing of large-scale forging part, must adopt large-scale or ultra-large type forging equipment with whole plane effect, thereby apparatus expensive, and the product precision is low, and work situation is abominable.

China utility model CN2072015U title: " hydraulic press rotation spreading head " discloses a kind of by the spreading head, rotating mechanism, hydraulic drive, pedestal four parts constitute, it is characterized in that: whole rotating mechanism and four pairs of bearings join together, be contained on the hydraulic press, pressure oil makes the rotation of spreading head by hydraulic drive, and the workpiece feeding of hydraulic press self makes its moulded head on workpiece, finishes the pressure processing to workpiece in screwfeed.

This type of hydraulic press rotation spreading head is α/2 angles because its rotating spindle and supporting base and vertical shaft incline respectively.Need two cover fixing and locking devices, complex structure, it is inconvenient to adjust maintenance, because the swing of spreading head has reduced housing rigidity, has shortened bearing life.Owing to adopt the slip bulb, power consumption is big, serious wear in addition.

The utility model purpose provides a kind of non-swing type rivet bucker, does not have swing during the work of spreading head, no alternate load effect, thereby frame is stressed good, and the rigidity height, intensity is big.

A kind of non-swing type rivet bucker, comprise the spreading header structure, Working table structure is characterized in that: connect the taper patrix under the spreading head, the ram shaft both sides are rolled in the top, there is large-scale thrust bearing the underbeam below, arc component is arranged below putting the beams in place, there is locking device on both sides, roll over ram shaft and become the γ angle with main shaft, and the γ angle is 0 °～15 °, have large size bearing to support also under the workbench and link to each other with sill, the splined cover on the power transmission shaft of workbench links to each other with fluid pressure drive device.Arc component has scale on (4).

Adopt such scheme, because the spreading head tilt is fixed, only rotate around himself axis, or according to the friction driven rotary of the metal works in the counterdie, so do not swing, therefore frame there is not the alternation eccentric load, improve the rivet bucker housing rigidity greatly, increased the service life of rolling bearing, consumed power is little, easily processing and manufacturing, easy to maintenance.

The non-swing type rivet bucker of Fig. 3 working motion form schematic diagram.

Below in conjunction with description of drawings embodiment.

A kind of as described in Figure 1 non-swing type rivet bucker, comprise the spreading header structure, Working table structure, it is characterized in that: spreading connects taper patrix 76 time, ram shaft 2 both sides are rolled in the top, there is large-scale thrust bearing 5 underbeam 8 belows, and there is arc component 41 below of putting the beams in place, and there is locking device 3 on both sides, roll over ram shaft and become the γ angle with main shaft, the γ angle is 0 °～15 °.On the arc component 4 scale is arranged.

The spreading header structure adopts rolling bearing type spreading head as shown in Figure 1, oil motor is done hydraulic drive in its structure, drive and roll over the ram shaft rotation, promptly drive spreading 6 rotation, the spreading head links to each other with underbeam by large-scale thrust bearing 5, roll over ram shaft and become a fixed angle r with machine shaft, the r angle is adjusted between 0 °～15 °, when adjusting angle, unclamp the retaining mechanism 3 of arc component 4 both sides earlier, on arc component 4, slide then, arc component 4 also can have scale, deflection angle is described, adjust to the anticipation angle after, be locked with locking device 3 and promptly finish adjustment process.

Workbench has for 8 times large size bearing 9 to support and links to each other with sill 10 as described in Figure 2, and the splined on the power transmission shaft 11 of workbench 8 is overlapped 13 and linked to each other with fluid pressure drive device 14.

As shown in Figure 3, because axially-movable has two kinds, a kind of is the feeding downward vertically of spreading head, and workbench does not axially move.Another kind is the workbench rectilinear motion that makes progress, and the spreading head does not axially move.

Three kinds of forms have rotatablely moved: the one, and spreading head and circular table rotate in the same way, and the two is the active rotation motion.The 2nd, the rotation of spreading head, workbench relies on the friction driven rotary of patrix and metal works.The 3rd, the workbench rotation, the spreading head relies on the driven rotation of frictional force.Thereby make metal works finishing the continuous local plastic distortion in the mould up and down, reach the monolithic molding purpose.

Above-mentioned drive unit also can adopt machine driving except driving with fluid power.
