Problems solved by technology

From the current process analysis, the surface carburizing and quenching process is poor, and it is not easy to meet the process requirements. There are often problems such as early wear-through or brittle cracks due to too high hardness of the contact surface. An alternative process is urgently needed to improve the wear resistance of this part. , in order to obtain a high wear-resistant skateboard seat

Embodiment 1

[0020] Embodiment 1: A high wear-resistant skateboard seat, the sliding surface of the high wear-resistant skateboard seat is provided with 4 grooves keeping a certain distance from each other along the arc direction of the sliding surface, and the 4 grooves are The grooves are evenly distributed, and the arrangement direction of the grooves is consistent with the direction of the center line of the arc surface of the sliding surface. The grooves are filled with hard steel fillers. The cross-section of the grooves is semicircular, and the diameter of the semicircle is φ10.

Embodiment 2

[0021] Embodiment 2: A high wear-resistant skateboard seat, the sliding surface of the high wear-resistant skateboard seat is provided with 6 grooves keeping a certain distance from each other along the arc direction of the sliding surface, and the 6 grooves are Evenly distributed, the arrangement direction of the groove is consistent with the direction of the center line of the arc surface of the sliding surface, the groove is filled with hard steel filler, the cross section of the groove is semicircular, and the diameter of the semicircle is φ12.

[0022] As a transformation of the first and second embodiments above, the number of grooves can be determined according to needs, generally 4-12; The diameter is generally between φ10~φ12; the shape of the cross section of the groove can also be other shapes, such as arc or inverted trapezoid or inverted triangle, etc. The depth and width of the groove are generally controlled within the semicircle of the groove with a semicircular...

Embodiment 3

[0023] Embodiment 3: A method for manufacturing a highly wear-resistant skateboard seat, the method includes the following steps:

[0024] A. Pre-casting groove: when casting the skateboard seat, grooves are pre-cast on the sliding surface of the skateboard seat and along the arc direction of the sliding surface according to the required number and shape;

[0025] B. Groove surface treatment: Shot peening the groove surface to eliminate casting stress and clean impurities on the groove surface at the same time;

[0026] C. Preheating of the welding substrate: preheat the welding substrate of the sliding seat to 130°C;

[0027] D. Overlay welding groove: use EDPCrMo-A4-03 electrode that meets the requirements of GB / T 984-1985, use manual arc welding machine welding to apply hard steel electrode surfacing welding to the groove, welding voltage is 70V, electrode surfacing current Take 200A to fill the groove with hard steel filler, and the hardness of the surfacing layer meets t...

Abstract

The invention discloses a high-abrasive resistance slide plate chair. The slide surface of the high-abrasive resistance slide plate chair is provided with N numbered grooves along with the arc direction of the slide surface, wherein the N numbered grooves have a certain distance from one another; the grooves are filled with rigid steel materials; and the cross sections of the grooves are in a semi circular shape, an arc shape, an inverted trapezoid shape or an inverted triangular shape. The production method of the high-abrasive resistance slide plate chair comprises: the grooves are precast on the slide surface along with the arc direction of the slide surface, the grooves are subject to surface treatment, a welding substrate is preheated, rigid steel welding strips are overlaid on the grooves, the welding substrate is cooled gradually, the grooves are subject to welding face treatment, and the like. The method is simple, is convenient to operate and is easy to popularize, the welding parameters can be adjusted and controlled, suitable rigid steel welding strips can be selected according to practical conditions, the slide surface reached the rigid degree for use, and the high-abrasive resistance slide plate chair is manufactured on the premise of not changing the appearance structure of the original sliding chair, and has the advantages of high abrasive resistance performance, low cost, economical efficiency and practicability.

Description

【Technical field】 [0001] The invention relates to an automobile component and a manufacturing method thereof, in particular to a highly wear-resistant skateboard seat and a method for manufacturing the high-wear-resistant skateboard seat. 【Background technique】 [0002] The door-type skateboard seat on the double axle of the automobile is generally a steel casting. Since the automobile leaf spring sheet slides heavily on the contact surface (sliding surface) with the skateboard seat, the contact surface must be carburized and quenched to make it A certain hardness, thereby improving wear resistance. From the current process analysis, the surface carburizing and quenching process is poor, and it is not easy to meet the process requirements. There are often problems such as early wear-through or brittle cracks due to too high hardness of the contact surface. An alternative process is urgently needed to improve the wear resistance of this part. , in order to obtain a high wear...
