Abstract

A double-roller aluminium alloy roller machine is disclosed, for performing pressing and side-rolling processing on the automobile parts of a damper cover and a damper seat to obtain an integer, wherein a rolling device is formed as follows: one end of a link is connected to the piston rod of a rolling cylinder, the link is movably connected to a cylinder seat, the other end of the link is fixed on a slide body, and the slide body is connected with a clamping die shaft which is connected with a bearing and a bearing cover to be an integer; a side-rolling device is formed as follows: a side-rolling cylinder is fixed on an outer barrel, a body with rollers is connected to the piston head of the side-rolling cylinder, the body is sleeved outside the slide body, and the outer barrel and a spray gun are fixed on the cylinder seat. The two devices are sleeved coaxially and operated in the same direction, which reduces the relative movement between the body and the slide body; the side-rolling processing is performed after the clamping die shaft tightly presses the damper cover and a liquid wax is sprayed instantaneously to reduce a friction force; the double-roller aluminium alloy roller machine has a high processing precision, eliminates the phenomena of breakage, crack and burr in rolling, efficiently enhances the product quality, has a product pass rate up to 99.9%, and greatly decreases the production cost. The rollers are directly installed on the body without a roller seat, so that the structure is simple and compact, and the volume is small.

Description

Twin roller type aluminium alloy roller press

Technical field

The utility model relates to a kind of roller press, particularly a kind of auto parts damper cap and shock absorber bearing are suppressed, and rolling is processed into the whole twin roller type aluminium alloy roller press that uses.

Background technology

Auto parts can be used the technology of a lot of chipless moulding in production and processing.

But existing roller press is especially in to aluminum alloy part crimping process; Can cause the burr and the phenomenon of rupture of part edge because of the extension of its moment, pulling force, pressure, frictional force that high-speed friction produced; Particularly require higher to safety resistibility requirement higher automobile absorber and space product; Therefore the fraction defective in manufacture process is high reaches 40%, thereby causes the high drawback of production cost.

Chinese patent number 200920209874.2 " passenger car steel wheel rim edge knurling machines "; Chinese patent number 200820088746.2 " a kind of novel crimping machines "; What provided all only is the roller press that a kind of part is carried out rolling, crimping processing use, and its function is more single.

One Chinese patent application number 200710018614.2 " a kind of electric capacitor porcelain bushing shell and cap connecting rolling press "; Can two or more part roll extrusion be connected into whole roller press though also provide a kind of; But its structure is complicated, part is many, volume is big, and is the special-purpose roller press that is used for power industry electric capacity lead-in wire porcelain bushing shell and cap connection.

Summary of the invention

The utility model technical problem to be solved is: a kind of twin roller type aluminium alloy roller press is provided; Can a plurality of parts be suppressed, be coated and fixed whole; This roller press is simple in structure, compact, volume is little, and machining accuracy is high, can thoroughly eradicate phenomenons such as fracture that aluminum alloy part occurs in the roll extrusion process, crackle, burr; Effectively promote product quality, greatly reduce production cost.

The utility model addresses the above problem the technical scheme that is adopted: twin roller type aluminium alloy roller press; Comprise that rack-mounted motor is connected with main shaft through belt pulley, belt; The power set that main shaft and rotating seat connect and compose; And the button that is installed on rolling device, binding device and the frame on the cylinder seat of frame forms, and is connected with an end of connecting rod on the piston rod of described rolling device by the roll extrusion cylinder, and said connecting rod is movably connected on the cylinder seat; The other end of connecting rod is fixed on the slide body, and said slide body connects into integral body with the clamping axle that is connected with bearing and bearing cap; Said binding device is by the rolling cylinder that is fixed on the urceolus, and is connected with the body of band roller on the piston head of rolling cylinder, and body is enclosed within outside the slide body, and urceolus is fixed on the cylinder seat to be formed, and also is fixed with on the said cylinder seat and stores up the spray gun that the wax bucket is connected.

Compared with prior art; The advantage of the utility model is: twin roller type aluminium alloy roller press, though the roll extrusion on it, binding device are driven by independently two driving cylinder roll extrusion cylinders, the control of rolling cylinder, stream oriented device connects with connecting rod and coaxial being linked in together can be along equidirectional operation; Relative motion and frictional dissipation between body and slide body have been reduced; And coaxial again rolling is processed after can guaranteeing the tight damper cap of roll extrusion clamping axial compression, thereby has guaranteed the rolling quality, because of coaxial rapid processing; Improved machining accuracy greatly, made properties of product stable simultaneously.Other two self-contained units cover integrator; The floor space minor structure is compact, and the roller roller-less seat that rolling is used is directly installed on the body good processing stability; And roll extrusion, rolling two cylinders all be installed on the same cylinder seat, and be therefore simple and compact for structure, part is few, volume is little.In addition in moment that crimping begins; By the instantaneous injection liquid wax of spray gun; Provide lubricated, reduce frictional force, thoroughly eliminate the unfavorable factor that burr after the roll extrusion, peeling, fracture, crackle etc. influence product function, make the qualification rate of product bring up to 99.9% from 40%; Not only promoted product quality greatly, also significantly reduced production costs.
