Abstract
The utility model relates to a transfer container for valve transportation, in particular to a reloading device for valve straightening. The reloading device comprises a blanking frame, a valve switching mechanism and a pushing cylinder, wherein the valve switching mechanism comprises a first stop lever and a second stop lever which are inserted in the blanking frame horizontally, the distance between the first stop lever and the second stop lever is smaller than the diameter of a valve retainer by 1-5 mm, the two stop levers are connected through return wheels fixed in the center, a push rod of the pushing cylinder is fixedly connected with a U-shaped push rod, an upper push rod of the U-shaped push rod is oppositely arranged with the first stop lever at an interval, a lower push rod of the U-shaped push rod is oppositely arranged with a valve rod which is in correction, and a direction changing section is arranged at the bottommost end of the blanking frame. The transfer container has the benefits as follows: valves can be straightened one by one sequentially by means of the reloading device for valve straightening in a valve straightening process.
Description
Technical field
The utility model relates to the auxiliary body that produces valve, particularly the material-changing device of valve alignment.
Background technology
Valve is the important spare part of engine interior, and therefore present each enterprise is very high to the quality requirement of valve.The valve of internal combustion engine is that lower work in the particular surroundings such as high corrosion and high-frequent reciprocating motion, has determined that valve must have higher red hardness, geometric accuracy and some special characteristics in high-air-tightness, high temperature, high pressure, high friction because of it.This just requires what precision of valve blank high, and internal stress is little.Blank alignment process after forging forming and heat treatment seems particularly important.The upper work of existing valve blank machine is: with conical surface location, bar portion completes the alignment of part in the thread rolling mode of rubbing between two washboards.In the time of alignment time, valve blank is subject to bar footpath to change impact greatly, straightener by roller now, by separate type pair of rollers valve stem and valve retainer alignment simultaneously, improve the qualification rate of valve alignment, roller once can only carry out alignment to a valve, now need the valve of controlling stock shelf to fall successively, if well do not controlled, must affect the alignment efficiency of valve.
Utility model content
The purpose of this utility model is will solve valve in the process of alignment valve, to be not easy to control the valve problem of alignment successively.
In order to address the above problem, the material-changing device of the valve alignment that the utility model provides, comprise blanking rack, valve switching mechanism and pusher cylinder, described valve switching mechanism comprises the first and second levers, described first, the second lever is laterally inserted in blanking rack inner side, first, distance between the second lever is than the little 1～5mm of valve retainer diameter, two levers connect by the fixing reply wheel in center, the push rod of described pusher cylinder is fixedly connected with U-shaped push rod, the upper push-rod of U-shaped push rod and the first lever relative gap arrange, the lower push-rod of U-shaped push rod is oppositely arranged with the valve stem of proofreading and correct, described blanking rack is provided with break-in section bottom.
Use the utility model has the advantage of: in the time that a collection of valve that need to proofread and correct is put into blanking rack, valve is supported and is formed gap by valve retainer in blanking rack, the first lever initial position is the valve that does not block the second correction, the second lever initial position is to block the valve that will proofread and correct, in the time that valve needs continuous correction, promote U-shaped push rod by pusher cylinder, U-shaped push rod promotes the first lever simultaneously and releases the valve of having proofreaied and correct, in the time promoting the first lever, due to first, movable toward each other by the fixing reply wheel in center between the second lever, make the first lever block the valve of the second correction, unclamp the first lever, making the valve of below enter between roller along slide rail proofreaies and correct, U-shaped push rod high-ranking officers' valve release just in time fast simultaneously, after pusher cylinder is replied, stop gauge returns to initial position.
Preferably, rock in order to prevent that first, second pin pushing course from existing, described first, second lever is slidably fitted in a pair of fixing sliding sleeve, by fixing sliding sleeve, lever vertical direction is retrained, and makes lever there will not be and rock at motion process.
Preferably, in order to there is the changing of the relative positions in anti-air-stop gate on valve frame, cause valve to be slipped to the situation that roller place occurs that blanking is not in place, in described blanking rack, be provided with the backgauge slide rail that blocks valve retainer, by backgauge slide rail, when valve level enters roller, can effectively stop valve to skid off blanking rack.
Brief description of the drawings
Fig. 1 is the structural representation of the material-changing device of the valve alignment of the utility model embodiment.
Detailed description of the invention
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
The material-changing device of valve alignment as shown in Figure 1, comprise blanking rack 9, valve switching mechanism and pusher cylinder 1, valve switching mechanism comprises the first and second levers 4, 5, first, the second lever 4, 5 are laterally inserted in blanking rack 9 inner sides, first, the second lever 4, distance between 5 is coiled the little 2mm of diameter than valve 8, two levers connect by the fixing reply wheel 6 in center, the push rod of pusher cylinder 1 is fixedly connected with U-shaped push rod 2, the upper push-rod of U-shaped push rod 2 and the first lever 4 relative gap settings, the lower push-rod of U-shaped push rod 2 is oppositely arranged with the valve stem of proofreading and correct, blanking rack 9 is provided with break-in section bottom.
In the time that a collection of valve that needs to proofread and correct is put into blanking rack 9, valve is supported and is formed gap by valve retainer in blanking rack 9, the first lever 4 initial positions are the valves 8 that do not block the second correction, the second lever 5 initial positions are to block the valve that will proofread and correct, in the time that valve 8 needs continuous correction, promote U-shaped push rod 2 by pusher cylinder 1, the valve 8 that U-shaped push rod 2 promotes the first lever 4 simultaneously and proofreaied and correct, in the time promoting the first lever 4, due to first, the second lever 4, movable toward each other by the fixing reply wheel 6 in center between 5, make the first lever 4 block the valve of the second correction, unclamp the first lever 4, making the valve of below enter between roller 10 along slide rail proofreaies and correct, U-shaped push rod 2 of while fast high-ranking officers' valve 8 is just in time released.
First, second lever 4,5 is slidably fitted in a pair of fixing sliding sleeve 3, by fixing sliding sleeve 3, lever vertical direction is retrained, and makes lever there will not be and rock at motion process.In blanking rack 9, be provided with the backgauge slide rail 7 that blocks valve retainer, when entering roller 10 by backgauge slide rail 7 valve levels, can effectively stop valve to skid off blanking rack 9.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
