Abstract
The present invention discloses a technique for forging an electric upsetting steel tie rod cap, wherein the technique for forging the electric upsetting steel tie rod cap comprises the following steps: placing one end of the steel tie rod to be upset on an electric upsetting machine; clamping a forging ball type electrode on the end to be upset, orienting the forging ball type electrode for facing the cap of the end to be upset; exerting current to the electrode for heating one end of the end to be upset; exerting an axial upsetting force in the axial direction of the steel tie rod to the end to be upset for upsetting the workpiece, and adjusting each parameter so that the rod body of the steel tie rod obtains the required shape and the required dimension. The technique for forging electric upsetting steel tie rod cap according to the invention has the advantages of few working procedures, little used heat and little expense for using the mold.
Description
Technical field
The present invention relates to a kind of metal working process, relate in particular to a kind of termination Forging Technology.
Background technology
Existing reinforcing pull rod termination Forging Technology, an end of reinforcing pull rod has one section long screw thread, and the pyriform earrings is bigger than the diameter of its required matrix size reinforcing pull rod body.This just requires this section blank diameter thicker than body.Production method is reinforcing pull rod body one end suitable length to be put into heating furnace be heated to malleable temperature routinely, from stove, take out to put it in jumping-up or the upsetting barrel die chamber, with horizontal forging and upsetting machine with its jumping-up to the size that requires.There is the spheroid of an approximate ball at the other end initial stage of manufacturing of reinforcing pull rod body.The process manufactured of method is routinely: an end suitable length of reinforcing pull rod body is put into be heated to malleable temperature in the stove earlier, taking-up is put it in jumping-up die cavity into, take out again to put into after with horizontal forging and upsetting machine and reheat malleable temperature in the stove its jumping-up, take out again, put into the upsetting barrel die chamber again and it is upset " ball " with another horizontal forging and upsetting machine again.This conventional method production need be on four stations, and jumping-up is carried out one time in heating respectively on two horizontal forging and upsetting machines at twice, and the ball of once upsetting just can be finished the work., required time of mobile station is many, and workpiece shift causes more thermal loss.Use mould will adopt expensive mold materials and processing maintenance cost height.Equipment uses also many.
Summary of the invention
For solve in the Forging Technology of existing reinforcing pull rod termination operation many, use that heat is many, the many technical deficiencies of mould cost, the purpose of this invention is to provide that a kind of operation is few, the use heat is few, do not use the technique for forging electric upsetting steel tie rod cap of mould or use simple mould.
As follows in order to realize the technical scheme that goal of the invention of the present invention adopts:
A kind of technique for forging electric upsetting steel tie rod cap is characterized in that: the step that described reinforcing pull rod termination Forging Technology comprises is:
1, the desire of the reinforcing pull rod end of upsetting is placed on the electric upsetter;
2, rammer ball-type electrode on described desire is upset end folder, rammer ball-type electrode is towards the upset termination of an end of desire;
3, electrode is passed to the described desire of the current flow heats end of upsetting;
4, impose axial upset force in order to jumping-up workpiece towards the described desire end of upsetting at reinforcing pull rod on axially, adjust parameters and make the body of rod of reinforcing pull rod reach desired shape and size.
The step that described reinforcing pull rod termination Forging Technology comprises is:
1, the desire of the reinforcing pull rod end of upsetting is placed on the electric upsetter, the middle part folder of reinforcing pull rod is established clamp, and the other end section folder of reinforcing pull rod is established expansion bearing;
2, at the described desire end folder top electrode of upsetting, one of them electrode is set as the rammer ball-type, be half arc ball-type groove, be connected and fixed with electric upsetter, be located at the upset outside of termination of an end of described desire, groove is towards the upset termination of an end of desire, and another electrode holder is in the upset inboard of position, an end of desire, and another electrode moves with reinforcing pull rod;
3, electrode being passed to low-voltage and high-current utilizes electrocaloric effect to heat the described desire end of upsetting;
4, in heating time, impose axial upset force in order to jumping-up described desire a upset end towards the described desire end of upsetting at reinforcing pull rod on axially, adjusts parameters and make the body of rod of reinforcing pull rod reach desired shape and size.
Described rammer ball-type electrode is fixedlyed connected with the hammering block oil cylinder of electric upsetter.
Described in step 3 heating-up temperature be the 800-1200 degree; Described low-voltage and high-current is alternating voltage 7-10 volt, and electric current is more than or equal to 1000 amperes.
Beneficial effect of the present invention:
1, conventional method production need be on four stations, and jumping-up is carried out one time in heating respectively on two horizontal forging and upsetting machines at twice, and the ball of once upsetting just can be finished the work.And adopt electric rammer method to produce as long as on same station, just can finish the work, and saved the required time in the workpiece transmittance process widely, and the loss of workpiece heat in the transmittance process, the occupancy volume of also having saved equipment.
2, electric rammer method is produced and is not used mould to save expensive mould metal material and processing maintenance cost thereof in the upsetting process.
3, method production homogeneous heating, speed is fast, and oxide skin is few, the forging quality height.
4, electric rammer method production use equipment obviously is less than conventional method production.
