Abstract
The utility model discloses a bearing bush machining structure which comprises an air cylinder mounted on a die shank of a punch press. Upper positioning columns are mounted on the two sides of the lower end face of the air cylinder, a punch is mounted at the end of a piston rod of the air cylinder, the end face of the punch is an arc face, and a concave die which is fixed on a lower die of the punch press is arranged under the punch. An arc-shaped groove matched with the outer wall of a bearing bush is formed in the middle of the concave die, and the upper end face of the concave die is provided with lower positioning columns which are placed on the two sides of the arc-shaped groove and correspond to the upper positioning columns. A limiting sensor contact is mounted on the right side wall and the left side wall of the air cylinder, and a first limiting sensor and a second limiting sensor are distributed on the outer side of the limiting sensor contact in the up-down direction in a spaced mode. The bearing bush matching structure is novel in structural design, the bearing bush with the large-dimension radius is machined to be in the dimension of finished products at one time in the punching, bending and forming process, the subsequent single process of pulling counter planes is avoided, high radius broaching allowance does not need to be reserved, raw materials are saved, and production efficiency is improved.
Description
technical field:
The utility model relates to bearing shell processing, relates in particular to a kind of bearing shell processing structure.
background technology:
At present, in well-known bearing shell work flow, in the time rushing curved molding procedure, bearing bush radius projection high (semi-circumference grow tall out-degree) all needs reserved certain broaching remainder, in following process, draw this requisite operation of counterpart, process comparatively accurately bearing bush radius projection is high to reach.Because bearing shell manufacturing procedure increases, and rush curved operation need to be for drawing counterpart operation to reserve allowance below, thereby cause its processing charges and material cost to increase, efficiency is low, process flow is long, and radius height is the critical size of bearing shell, and its required precision is high, draw counterpart operation to adjust complicated, production capacity is low.
utility model content:
In order to make up prior art problem, the purpose of this utility model is to provide a kind of bearing shell processing structure, in bearing shell process, bearing bush radius projection height does not need through this independent operation of broaching processing, need not reserve the waste of material that allowance causes because of broaching processing, can ensure again radius high accuracy, significantly enhance productivity and save product cost simultaneously.
The technical solution of the utility model is as follows:
Bearing shell processing structure, it is characterized in that: comprise the cylinder being installed on punch press die shank, the both sides, lower surface of cylinder are provided with locating dowel, the piston rod end of cylinder is provided with drift, the end face of drift is cambered surface, under drift, be provided with the die being fixed on punching machine lower mold, the middle part of die is provided with the deep-slotted chip breaker matching with bearing shell outer wall, the upper surface of die is positioned at the deep-slotted chip breaker both sides lower locating dowel corresponding with upper locating dowel, the right side wall left side wall of described cylinder is provided with limit induction device contact, outside, limit induction device contact is provided with along upper and lower the first limit induction device spaced apart, the second limit induction device.
Described bearing shell processing structure, is characterized in that: the end face of described cylinder is provided with the guide cylinder passing for cylinder piston rod, and the lower surface of guide cylinder is provided with cushion pad.
The utility model has the advantages that:
The utility model structural design novelty curves type in punching, to the disposable finished size that is worked into of the high size of bearing bush radius projection, has exempted and has drawn this independent operation of counterpart plane below, does not need the reserved high broaching remainder of radius simultaneously, has saved raw material, enhances productivity.
brief description of the drawings:
Fig. 1 is structural representation of the present utility model.
detailed description of the invention:
Referring to accompanying drawing:
Bearing shell processing structure, comprise the cylinder 2 being installed on punch press die shank 1, the both sides, lower surface of cylinder 2 are provided with locating dowel 3, the piston rod end of cylinder 2 is provided with drift 4, the end face of drift 4 is cambered surface, under drift 4, be provided with the die 5 being fixed on punching machine lower mold, the middle part of die 5 is provided with the deep-slotted chip breaker 6 matching with bearing shell outer wall, the upper surface of die 5 is positioned at the deep-slotted chip breaker 6 both sides lower locating dowel 7 corresponding with upper locating dowel, the right side wall left side wall of cylinder 2 is provided with limit induction device contact 8, 8 outsides, limit induction device contact are provided with along upper and lower the first limit induction device 9 spaced apart, the second limit induction device 10.
The end face of cylinder 2 is provided with the guide cylinder 11 passing for cylinder piston rod, and the lower surface of guide cylinder 11 is provided with cushion pad 12.
The bearing shell sheet stock of needs processing is placed on die 5, in the time of cylinder 2 operation downwards, first limit induction device contact 8 on cylinder 2 approaches the first limit induction device 9 that is arranged on left side, now trigger induction installation, making cylinder 2 promote piston rod moves downwards, thereby make to be connected to drift 4 on piston rod the bearing shell sheet stock of needs processing is pressed to the inner circle of die 5, bearing shell sheet stock is carried out to pre-bending and make it to become a semicircular;
In the time that cylinder 2 continues to come downwards to the second limit induction device 10 that limit induction device contact 8 reaches left side, again trigger induction installation, now the downstream rate of cylinder 2 is because the control being cushioned slows down, and cylinder 2 is with slowly operation downwards of guide cylinder 11;
After the guide cylinder 4 of installing on cylinder 2 contacts with the bearing shell that is pre-bent in advance semicircular by drift 5, form a squeezing action in bearing shell counterpart plane, after the contacting of upper locating dowel 3 and lower locating dowel 7, the descending position of guide cylinder 11 is fixed, now the radial height of bearing shell also forms a fixing numerical value, thereby realize when punching curves type, to the high disposable needed accurate dimension of finished product that is worked into of bearing bush radius projection, subsequent handling without independent draw counterpart plane operation pair radius be high again carry out fine finishining.
