Abstract

The utility model relates to the technology of liner bushing (sliding bearing) manufacture, in particular to a liner bushing manufacturing device which comprises positioning plates; punch holes are formed on die seats of the positioning plates; female dies are arranged on the positioning plates; die holes with kentanium hole walls are formed in the female dies, and are positioned on the punch holes of the positioning plates; the inside diameter of the punch hole of at least one positioning plate is smaller than the inside diameter of the die hole; the inside diameter of the punch hole of at least one positioning plate is larger than the inside diameter of the die hole; the lower end of a pressing machine is respectively connected with a male die and a post rod; the outside diameters of the male die and the post rod are respectively smaller than the inner diameter of the die hole; and the liner bushing manufacturing device is also provided with a male extrusion die, and the outer diameter of the male extrusion die is smaller than that of the die hole. The utility model mainly solves the technical problem that the production efficiency is low because of the use of machine work (such as grinding, internal boring and broaching) in the existing processing method. When the liner bushing manufacturing device is used, the inner diameter is processed before the liner bushing is pressed into product components; the production efficiency of the pressing machine is high; and the work cost is low.

Description

A kind of device and lining of making lining

Technical field

The utility model relates to makes lining (sliding bearing) technology, especially a kind of device of making lining.

Background technology

Lining is product common parts such as automobile, internal combustion engine, engineering machinery.The material of lining is a composite, and commonly used have steel backing-bronze, steel backing-acieral, a steel backing-copper alloy-polytetrafluoroethylene (PTFE) (or polyformaldehyde).Lining pattern in the longitudinal direction has the branch of opening and hasp.The external diameter of lining is pressed in the hole of product component, adopts interference fit, and the axle of internal diameter and parts is a matched in clearance.

Traditional processing method is: the extrusion process of stamping technology is adopted in the fine finishining of broached bushing external diameter, and the hasp lining adopts method for grinding behind the Sheet Metal Forming Technology polishing.No matter be opening, the lining that hasp is arranged, its internal diameter all leaves the allowance of 0.3-0.4mm, is pressed in the product component hole by main engine plants, carries out machining technologies such as (mill, boring) drawing and sees Fig. 1.The method of inspection of regulation is the external diameter that will process, be pressed in the given entity hole of pattern, with feeler gauge end, the go side checks.Main engine plants are pressed into lining in the member apertures of product like this, not in processing, both directly use, and see Fig. 2.

In the above-mentioned existing processing method, all adopt machining (as grinding, bore hole, broaching) productivity ratio low.Parts are generally housing class, gear class, and volume, weight are bigger, transportation, trouble are installed, and also exclusive clamping apparatus will be arranged.And because the positioning accuracy request height of product, therefore, this processing method is consuming time many, and expense is higher.

The utility model content

The purpose of this utility model is to provide a kind of device of making lining, mainly solve in the existing processing method, all adopt machining (as grinding, bore hole, the broaching) technical problem that productivity ratio is low, adopt this device, before lining is pressed into product component with the internal diameter completion of processing, forcing press production efficiency height, the frock expense is lower.

For addressing the above problem, the utility model is achieved in that

A kind of device of making lining is characterized in that: it comprises the location-plate that has perforation on the die holder, on this location-plate die is set, and has the nib of carbide alloy hole wall in the die, and this nib is positioned on the perforation of location-plate; Wherein, the punch inside diameter of at least one location-plate is less than the internal diameter of nib, and the punch inside diameter of at least one location-plate is greater than the internal diameter of nib; One forcing press lower end is connected with punch and push rod respectively, and the external diameter of punch and push rod is all less than the nib internal diameter; Also have the extruding punch of an external diameter in addition less than nib.

The device of described manufacturing lining is characterized in that: the nib upper end of described die has fillet.

Adopt the utility model device, before lining is pressed into product component,, overcome above-mentioned shortcoming the internal diameter completion of processing, forcing press production efficiency height, the frock expense is lower, so its economic benefit is considerable.

Fig. 4 is structure of the present utility model and user mode schematic diagram two.

The specific embodiment

The utility model provides a kind of device of making lining, shown in Fig. 3,4: it comprises the location-plate 5 that has perforation 51 on the die holder 6, on this location-plate 5 die 4 is set, has the nib 41 of carbide alloy hole wall in the die 4, this nib 41 is positioned on the perforation 51 of location-plate 5; Wherein, the punch inside diameter of at least one location-plate is less than the internal diameter of nib 41, and the punch inside diameter of at least one location-plate is greater than the internal diameter of nib 41; One forcing press, 7 lower ends are connected with punch 1 and push rod 2 respectively, and the external diameter of punch 1 and push rod 2 is all less than nib 41 internal diameters; Also have the extruding punch 3 of an external diameter in addition less than nib 41.Nib 41 upper ends of described die 4 have fillet.

When processing is used:

The right is an initial point state on the forcing press among Fig. 3, the initial mould closed height of adjusting, this lining upper end is inserted on the punch 1, the lower end is on the fillet of the nib 41 of die 4, forcing press 7 is to following initial point, and lining is advanced in the nib 41 of die 4 by punch 1, and extruding lining external diameter, internal diameter packs tightly on punch 1, finishes the right that Fig. 4 is seen in external diameter processing.

When forcing press 7 up strokes, die 4 (comprising the lining that external diameter pushes) is moved in the location-plate 5 on the left side among Fig. 3, and put into and push punch 3, forcing press 7 promotes extruding punch 3 to following initial point by push rod 2 and carries out the extruding of lining internal diameter, see Fig. 4 left side, finish lining internal diameter processing (extruding punch 3 falls).This moment, the interior external diameter of lining machined.

After initial manufacture is finished, promptly enter the ordinary production state, promptly the die 4 in Fig. 4 left side moves back in the location-plate on Fig. 3 the right, repeats the aforesaid operations program.(part in die 4 newly put into part eject).

Being preferred embodiment of the present utility model only in sum, is not to be used for limiting practical range of the present utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all should be technology category of the present utility model.
