Description
Technical Field
The invention relates to the technical field of heavy machinery, in particular to an extrusion needle loading and unloading system.
Background
When a heavy extruder with a weight of more than 5000 tons is used for producing the pipe by adopting an extrusion needle method, the shape and the size of an inner cavity of the pipe need to be determined by utilizing a needle point, and the needle point is fixed on a perforation supporting system consisting of an extrusion needle, a needle seat connecting rod and the like. The components of the support system are fastened by threaded connection. In order to ensure that the needle point plays a stable shaping role in the whole extrusion process, the needle point is not allowed to rotate along the extrusion axis, so that the extrusion needle, the needle seat and the needle seat connecting rod are required to be tightly screwed, and loosening cannot occur in the extrusion process, so that deflection of the needle point is avoided, and the tubular product cavity cannot meet the technical requirements.
In general, in order to effectively assemble the extrusion needle with the needle holder, a wire rope winding method is used in the production operation to mount and dismount the extrusion needle, namely: the small diameter end of the extrusion needle is wound with a steel wire rope for a plurality of circles, one end of the steel wire rope is pulled upwards by crane and other lifting equipment, and the other end of the steel wire rope is pulled manually to keep enough friction between the steel wire rope and the surface of the needle seat. Under the action of friction force, the extrusion needle rotates around the central shaft, rotates forward, tightens the needle seat, rotates reversely, and unscrews the extrusion needle.
The defects of the steel wire rope winding method for assembling and disassembling the extrusion needle are as follows: the steel wire rope clings to the outer diameter surface of the needle seat, the force arm generated by lifting is short, when the steel wire rope is pulled upwards, the extruding needle is easy to be lifted upwards, the concentricity of the external thread of the extruding needle and the internal thread of the needle seat is seriously deteriorated, the situation of 'seizure' is formed, and the extruding needle is not easy to screw up. Secondly, when needing powerful fastening, the other end is through the frictional force of manpower pulling reinforcing wire rope and extrusion needle, and operating personnel intensity of labour is big, and is difficult for producing sufficient frictional force and the phenomenon of skidding appears. Meanwhile, accidental breakage of the steel wire rope also easily causes personal injury to operators.

The opening degree of the bayonet at the head end of the open spanner 2 is selectable to ensure that the open spanner 2 can be fed from the side of the small diameter section 11 of the extrusion needle 1 so that the axes of the top surfaces of the jaws 22 are concentric with the axis of the extrusion needle 1. The opening degree is preferably 5-15mm larger than the diameter of the small diameter section 11 of the extrusion needle 1, and the tip opening degree in this embodiment is set to 320mm.
When the extrusion needle loading and unloading system is used, firstly, the open spanner 2 is moved to enable the small-diameter section 11 of the extrusion needle 1 to enter the bayonet, and the axis of the top surface of the claw 22 and the axis of the extrusion needle 1 are coaxial as much as possible; then, in the circumferential direction of the extrusion needle 1, the angle of the open spanner 2 is adjusted to enable the clamping claws 22 of the bayonet to be aligned with the clamping grooves 121 of the extrusion needle 1 one by one, and then the open spanner 2 is moved towards the clamping grooves 121 of the extrusion needle 1, and the clamping claws 22 are placed into the clamping grooves 121; finally, the open spanner 2 is lifted upwards from the tail end of the open spanner 2 by using the lifting rope, and the open spanner 2 and the extrusion needle 1 rotate around the axis of the extrusion needle 1, so that the aim of firmly or unscrewing the extrusion needle 1 is fulfilled.
The extrusion needle loading and unloading system solves the problems that the extrusion needle is not easy to screw up in the existing loading and unloading method and is easy to loose in the extrusion process; in addition, the setting of open spanner can reduce operating personnel intensity of labour by a wide margin to eliminate the security risk that current wire rope winding method was brought when operating.

Further, the bottom of the clamping groove 121 and the root of the claw 22 can be preferably arc surfaces, and all the arc surfaces are coaxial.
Typically, the width of the clamping groove 121 in the circumferential direction of the large diameter section 12 is slightly larger than the width of the claw 22, such as 2-5mm; the diameter of the circular arc surface at the bottom of the clamping groove 121 is slightly smaller than that of the circular arc surface at the top surface of the clamping jaw 22, for example, 3-8mm; the diameter of the arc surface between the roots of the clamping jaws 22 is optional, and is preferably 3-8mm larger than the diameter of the large diameter end 12 of the extrusion needle 1.
The number of the clamping jaws 22 in the clamping opening can be four, and the clamping jaws are symmetrically distributed in the clamping opening. Specifically, 1 can be arranged above and below the center of the arc, 1 can be arranged above and below the side of the bottom of the arc, and the corresponding claws 22 in the up-down direction are symmetrical to the center line of the open spanner 2 in the height direction; the angles between the side upper and side lower jaws 22 and the other adjacent jaws are 60 degrees, respectively.
In a specific embodiment, the open spanner 2 may be further provided with:
a tail catch hook 23 is arranged at the tail end of the force arm 21, a groove 24 is formed between the tail catch hook 23 and the upper side surface and the lower side surface of the force arm 22, and the groove 24 is used for limiting the lifting rope. The width and height of the grooves 24 may also be specifically set.
On the basis of the arrangement of the tail catch hook 23, a front catch hook 25 can be further arranged at the tail end of the arm 22, and a groove 24 is arranged between the front catch hook 25 and the tail catch hook 23. The front catch hook 25 and the rear catch hook 23 can be symmetrically arranged along the up-down direction of the arm 22 to prevent the lifting rope from sliding off the groove 24 after the stress direction of the lifting rope and the open spanner 2 is changed when the open spanner 2 is inclined. The height of the front catch 25 and the rear catch 23 is selectable, preferably 250-350mm.
As an improvement, a handle 28 may be further provided on the trailing end side of the arm 22 for manually balancing the open-ended wrench 2 during feeding operations of the open-ended wrench 2. When the wrench is used, the wrench is lifted from the lifting hole of the wrench by using the lifting rope, and the wrench is held by hand to keep stable.
A hanging hole 26 for hanging the open spanner 2 can also be arranged in the middle of the arm 22, and the hanging hole 26 is a through hole, preferably an oval through hole. The center of the hanging hole 26 coincides with the center of gravity of the open spanner 2, so that the balance of the spanner is easier to control when the open spanner 2 is lifted and fed through the hanging hole 26. The hanging hole 26 also has a weight reduction function.
In addition, a lifting lug 27 capable of threading a rope can be arranged on the head of the open-ended wrench 2.
