Description
Technical Field
The invention relates to the technical field of elevator accessory production processes, in particular to a rope head taper sleeve and a stamping production process thereof.
Background
The rope end taper sleeve is a fixing piece of a steel wire rope or a steel belt and is used for fixing the rope end of the steel belt or the steel wire rope and enabling the other end of the rope end taper sleeve to be connected with a lift car of the elevator. And the other end of the rope end taper sleeve is connected to the counterweight or the hoisting device through a rope end rod. When the existing rope head taper sleeve is installed, the complete vertical installation of a rope head rod must be guaranteed firstly, the vertical downward state cannot be guaranteed by the rope head taper sleeve on the side, the steel wire rope is subjected to acting force in other directions, the installation requirement is high, the difficulty is high, the installation task cannot be completed well, and the installation efficiency is low.
The existing rope end taper sleeve is generally processed by two methods of multi-component welding or integral molding casting. The welding process is adopted, and the formed rope end taper sleeve has a welding seam, so that the firmness is poor; and the process of integral molding casting is adopted, so that the cost of the casting process is high due to the fact that the process flow is more, and auxiliary raw materials are needed in the production process. Patent application No. CN201610075160.1 discloses a rope end taper sleeve and its production process, in which a stamping process of cold extrusion processing is adopted. Because the rope end taper sleeve is of a hollow structure and is processed by adopting a cold extrusion stamping process, if the stamping deformation of the rope end taper sleeve is large, raw materials are easy to crack, and the stamping failure is caused.
Disclosure of Invention
The invention provides the rope end taper sleeve and the stamping production process thereof, aiming at overcoming the problem that raw materials are easy to crack in the existing stamping processing process of the rope end taper sleeve in the prior art, so that the raw materials can be prevented from cracking in the stamping production process, and the yield is improved.
In order to solve the technical problems, the invention adopts the technical scheme that: a rope end taper sleeve comprises a square part, a conical part and a bearing part, wherein the conical part is provided with a cavity, and the bearing part is used for connecting the square part and the conical part; the bearing part is provided with a notch extending to the cavity, the square part is provided with a through hole used for being rotationally connected with the rope end rod, and the conical part is provided with a fixing hole used for fixing the baffle; an extension line of the inner wall of the conical part, which is far away from one side of the notch, penetrates through the through hole, and the linear distance between the extension line and the center of the through hole is 1-3 mm.
Rope end pole has some skew in the installation, does not keep completely in vertical state, because the through hole of rope end taper sleeve is connected with rope end pole is rotated, and rope end taper sleeve can rotate for rope end pole under the effect of gravity or the pulling force of steel band, makes self keep a vertical state, and the export of toper portion keeps vertical downwards, makes the steel band of dress in rope end taper sleeve can keep vertical decurrent state. The rope end conical head is adopted for connection and installation, even if a rope end rod deviates to some extent during installation and is not completely kept in a vertical state, the rope end conical head can also make the rope end conical head self keep a vertical state, the outlet of the conical part is kept downwards, and a steel belt arranged in a rope end conical sleeve can keep a vertical and downward state. The stable motion of the car connected with the steel belt is ensured, the installation difficulty of the rope head rod is reduced, and the installation efficiency is improved.
A punching production process of a rope end taper sleeve comprises the following specific steps:
the method comprises the following steps: blanking, namely adopting a seamless metal pipe;
step two: stamping the outer surface of one end of the metal pipe into a cone to form a cone part;
step three: stamping and shaping one end of the conical part of the metal pipe;
step four: punching a notch on the metal pipe;
step five: heating the metal pipe, and applying a stamping force to one side of the conical part, which is far away from the notch, so that the conical part deviates towards the direction close to the notch;
step six: after flattening and shaping the metal pipe, stamping and shaping one end of the metal pipe, which is far away from the conical part;
step seven: and machining a through hole on the metal pipe.
The tapered portion corresponds to the tapered portion, and the square portion corresponds to the square portion. Because the conical part of the rope end taper sleeve deviates to one side relative to the square part and the deviation amount is large, in the fifth step, before the conical part deviates due to the fact that one side of the conical part is punched, the metal pipe is heated, plasticity of the metal pipe is increased, and the metal pipe is prevented from cracking in the punching process.
Preferably, in the fifth step, the heating temperature is 520-580 ℃, and at this temperature, the plasticity of the metal tube is strong, and cracking does not occur during punching.
Preferably, in the third step, the press shaping includes two steps of outer shaping and inner shaping; and finishing the shaping of the surface of the conical part by a stamping die core wrapping the outer surface of the conical part, and finishing the shaping of the inner surface of the conical part by a stamping die core extending into the inner cavity of the metal pipe. The outer shaping is to shape the outer surface of the tapered part of the rope head taper sleeve, the inner shaping is to shape the inner wall of the tapered part of the rope head taper sleeve, and the inner surface and the outer surface of the tapered part can be formed into a smooth tapered surface by shaping the inner surface and the outer surface.
Preferably, in the third step, after the outer shaping step is completed, the metal pipe is subjected to stress relief annealing treatment. After the stress relief annealing, when the inner shaping step is performed, the cracking of the tapered portion can be avoided.
Preferably, the stress relief annealing is cooling in air after heating the metal tube to 500-600 degrees.
Preferably, the shot blasting treatment is performed on the metal pipe before the step four. The shot blasting treatment can remove the oxide skin of the metal pipe and the stress of the metal pipe.
Preferably, in the second step, the press working of the tapered portion is performed in two steps. Because the taper of the conical part is less and the length is larger, the quality of the formed product can be improved more favorably by separating the two times of stamping and stretching forming.
Preferably, in the sixth step, the entire metal pipe is flattened to a predetermined width, and then one end of the metal pipe away from the tapered portion is pressed to a square shape to form a square portion. After the overall shape of the metal pipe is kept at a certain width, one side of the metal pipe, which is far away from the conical part, is processed into a square part in a stamping and flattening mode, and the shape processing of the main body of the rope end conical head is completed.
Preferably, through holes are respectively machined in the tapered portion and the square portion. The through holes on the square part are through holes, and the through holes on the conical part are fixing holes. The through hole on the square part is processed by punching, and the through hole on the conical part is processed by drilling.
Compared with the prior art, the invention has the beneficial effects that: when the rope end taper sleeve to be produced has larger offset, the processing method in the scheme is adopted to heat the raw materials before stamping, so that the plasticity is increased, cracking is avoided in the process of metal pipe offset, and the yield of the rope end taper sleeve is improved.
