Abstract
The utility model discloses a kingpin crushing test mould mainly includes moulding-die, kingpin and sleeve in first interior moulding-die, the second, the sleeve in be equipped with the cross recess, be equipped with first interior moulding-die in the cross recess, be equipped with many kingpins on the first interior moulding-die, be equipped with moulding-die in the second on the kingpin, wherein many kingpins intercrossing stacks, moulding-die and cross recess are clearance fit in first interior moulding-die, the second, after crushing test accomplishes, can take out the kingpin of moulding-die and crushing in first interior moulding-die, the second smoothly in proper order from the sleeve. The utility model has the advantages that: the sleeve with the cross groove is adopted, so that the problem that the roller pins which are stacked in a crossed mode rotate and slide in the sleeve is solved; the utility model discloses a to the structural design of bearing pin crushing test mould, the simplified operation strengthens the practicality.
Description
Technical Field
The utility model belongs to the technical field of the pressure test mould is used, especially, relate to kingpin crushing test mould.
Background
The mould matched with the existing compression testing machine is not suitable for the roller pin, and a special roller pin crushing test mould is rarely sold in the market, so that the operation of the roller pin crushing test is limited.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the not enough of prior art existence, and provide a kingpin crushing test mould, through the structural design to kingpin crushing test mould, the simplified operation strengthens the practicality.
The purpose of the utility model is accomplished through following technical scheme. The needle roller crushing test die mainly comprises a first inner pressing die, a second inner pressing die, needle rollers and a sleeve, wherein a cross groove is formed in the sleeve, the first inner pressing die is arranged in the cross groove, a plurality of needle rollers are arranged on the first inner pressing die, the second inner pressing die is arranged on the needle rollers, the needle rollers are mutually overlapped in a crossed mode, the first inner pressing die, the second inner pressing die and the cross groove are in clearance fit, and after a crushing test is completed, the first inner pressing die, the second inner pressing die and the crushed needle rollers can be sequentially and smoothly taken out of the sleeve.
Furthermore, the first inner pressing die and the second inner pressing die are made of GCr15 material and need to be heat treated, and the sleeve is made of 45# steel material.
Furthermore, the cross-shaped groove is composed of a through round hole and two mutually perpendicular rectangular through grooves taking the round hole as the center.
The utility model has the advantages that:
1. the sleeve with the cross groove is adopted, so that the problems that the roller pins which are stacked in a crossed mode rotate and slide in the sleeve are solved.
Drawings
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a two-dimensional plan view of the sleeve.
Description of reference numerals: the device comprises a first inner pressing die 1, a second inner pressing die 2, a needle roller 3, a sleeve 4 and a cross groove 4-1.
Detailed Description
The present invention will be described in detail with reference to the accompanying drawings:
example 1: the needle roller crushing test die mainly comprises a first inner pressing die 1, a second inner pressing die 2, needle rollers 3 and a sleeve 4, wherein a cross groove 4-1 is formed in the sleeve 4, the first inner pressing die 1 is arranged in the cross groove 4-1, the first inner pressing die 1 is provided with the three needle rollers 3, the needle rollers 3 are provided with the second inner pressing die 2, the three needle rollers 3 are mutually overlapped in a crossed mode, the first inner pressing die 1 and the second inner pressing die 2 are in clearance fit with the cross groove 4-1, and after a crushing test is completed, the first inner pressing die 1, the second inner pressing die 2 and the crushed needle rollers 3 can be sequentially and smoothly taken out of the sleeve. Due to the adoption of the sleeve with the cross groove, the problems that the roller pins which are overlapped in a crossed mode rotate and slide in the sleeve are solved.
Example 2: on the basis of the embodiment 1, as shown in fig. 1, the first inner pressing die 1 and the second inner pressing die 2 both adopt GCr15 material and need heat treatment, and the sleeve 4 adopts 45# steel material. The hardness of the first inner pressing die and the second inner pressing die is more than 61HRC due to heat treatment.
Example 3: in addition to the embodiment 2, as shown in fig. 2, the cross-shaped slot 4-1 is composed of a through circular hole and two mutually perpendicular rectangular through slots with the circular hole as the center.
It should be understood that equivalent substitutions or changes to the technical solution and the inventive concept of the present invention should be considered to fall within the scope of the appended claims for the skilled person.
