Description

Punching structure profile shaft bearing

Technical field

The utility model relates to the bearing support technical field, is specifically related to a kind of punching structure profile shaft bearing.

Background technique

Bearing block is widely used in the various machinery, the equipment of Da Piliangshengchaning especially, and bearing support has formed the approved product of standardization, seriation.The existing bearing seat mostly is integral type, is that the material casting forms with grey cast iron (HT150 or HT200), divides upper and lower two-part on the structure, and top has been divided into the hull shape body that placed axis is made usefulness, in the middle of shell one side space that holds bearing is arranged; The bottom is divided into the grounding base that play fixed supporting role.This type of bearing support is a material because of adopting cast iron, and heavy, volume is big, outward appearance is clumsy; Aspect manufacturing process, to pass through ageing treatment behind the casting, also need car, mill, machining prefaces such as right boring, boring, coarse because of casting surface, also to handle usually, so how and complexity manufacturing procedure through beating outward appearances such as greasy japanning; Because of machining allowance is big, utilization rate of raw materials is low, produces in enormous quantities the raw material of total consumption and waste are increased; It is high that current domestic and international raw material market price continues, more than each factor determined that the cost of its manufacturing is higher.

Summary of the invention

The purpose of this utility model provides a kind of punching structure profile shaft bearing, to overcome above shortcomings in the existing background technique.

The technical solution of the utility model is:

Comprised that placed axis makes the upper body of usefulness and the lower body that play fixed supporting role, lower body is made up of base, wall and flange plate retaining wall, and base one side is connected with wall, and opposite side is connected with the flange plate retaining wall, and connects basic fixed hole in addition, and mounting hole is arranged on the wall; The caulking part position that tube and flanging are inserted by flange plate, bearing cartridge, location end wall, connection in the upper body is formed, bearing cartridge one end of placing bearing is connected with flange plate, the location end wall of the other end by playing interconnect function with is connected slotting and is connected, the fixed hole that connects end cap is arranged on the flange plate, connect and insert tube in mounting hole, its outer end is connected with by the flange riveting process and makes it abut against the riveted joint position of the flanging on the wall outer surface.

Flange plate leans against on the flange plate retaining wall.

Flange plate is circular, and the fixed hole of company's end cap of requirement is arranged above it, and above-mentioned each hole is to be the long arc-shaped holes that is evenly distributed on the circumference in the center of circle with the bearing cartridge endoporus.

Good effect of the present utility model is:

1, material is used carbon constructional quality steel (08F, 10 etc. low carbon steel plate) instead by original grey cast iron (HT150 or HT200), the available A3 steel plate low to bearing load, under the prerequisite of proof strength, product weight (only for former weight 1/4th) and volume had both been reduced, be convenient to accumulating, improved the outward appearance and the quality of product again, made on the product class;

2, processing technology by casting, ageing treatment, car, mill, right boring, boring, play greasy, japanning etc., be reduced to and have only impact briquetting and riveted joint, the machining accuracy of bearing cartridge endoporus can be guaranteed by mould, does not need other any machining preface (finish turning or boring);

3, because of adopting the punch forming process technology to be used for producing in enormous quantities, stock utilization significantly improves so machining allowance reduces;

4, simplified manufacturing process because of the optimization of product structure, reduced materials consumption, continued under the high situation in current domestic and international raw material market price, manufacture cost significantly reduces.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples.

Bearing support with 205 bearings is an example, and it is that raw material is produced in batches that upper body 1 and lower body 2 all adopt the thick 08F low carbon steel plate of 3mm, forms the structure shape (comprising that the institute above it is porose) shown in Fig. 3～6 after die stamping is shaped.

See Fig. 3 and Fig. 1, the riveted joint position 13 ' (punching press flange assembling back forms the riveted joint position 13 of flanging) that upper body 1 is inserted before tube 12 and the flange by flange plate 8, bearing cartridge 10, location end wall 11, connection is formed; Bearing cartridge 10 1 ends link to each other with flange plate 8, both have common bearing cartridge endoporus 10a, its machining accuracy is guaranteed by mould, do not need other any machining preface (finish turning or boring), the location end wall 11 that the other end has passed through interconnect function is inserted tube 12 and is linked to each other with being connected, and its outer end is connected with it with the riveted joint position 13 ' before the flange of shape; Flange plate 8 is circular, and 3 fixed holes 9 that are used for company's end cap of being connected with bearing (ball) cover are arranged above it, and above-mentioned hole is 3 long arc-shaped holes that are evenly distributed on the circumference in the center of circle being with bearing cartridge endoporus 10a.During practical application, the bearing (ball) cover (axle of connection bearing can be passed in the hole in the middle of it) that is ring is installed also on flange plate 8, has above it and fixed hole 9 corresponding 3 the end cap fixed holes that connect end cap.
