Abstract
The utility model relates to an extruding die for double-headed studs, which is characterized in that a body includes a first alloy block and a second alloy block. A first thread machining toothed groove and a second thread machining toothed groove are arranged on the inner upper side and the inner lower side of each of the first alloy block and the second alloy block respectively, a groove which is 4mm-6mm in depth is arranged between each first thread machining toothed groove and the corresponding second thread machining toothed groove, the first alloy block and the second alloy block are rectangular. When the extruding die is applied to automatic equipment, threads at two ends can be formed once, interference of a thick middle shank of a double-headed stud on one-step forming is avoided, and production efficiency is improved. Moreover, the rectangular external form of the stud is beneficial to mounting, and the stud can be mounted rapidly and conveniently.
Description
Technical field
The utility model relates to a kind of frock clamp, especially relates to a kind of studs extrusion die that the extruding of studs intermediolateral column is interfered that do not influence.
Background technology
Studs is a kind of securing member commonly used in the pair that is threaded; Screw thread is normally processed with rolling the tooth machine separately in batch process; Rolling the tooth machine is semiautomatic equipment; Relying on artificially will need the product at machining screw position to put between two rollers that roll the tooth machine, through hydraulic drive two roller centre-to-centre spacing dwindled product pushed forming screw thread again; Extrusion process screw thread like this, human factor exists many, and one of skilled worker's work output hourly is processed as finished product and has only about 300 about 600, and such efficient is too low, is unfavorable for the development of an enterprise.
Summary of the invention
The utility model technical problem to be solved provides a kind of high efficiency, the indeformable studs extrusion die of intermediolateral column is pushed in assurance simultaneously.
The technical scheme that its technical problem of the utility model solution is taked is: a kind of studs extrusion die; Main body is first alloy block and second alloy block; Offer first screw thread processing teeth groove and second screw thread processing teeth groove in the inboard of first alloy block and second alloy block up and down respectively, offer a groove between said first screw thread processing teeth groove and second screw thread processing teeth groove.
In order to guarantee that extrusion die can not cause extruding to interfere the intermediolateral column of studs in extruding, help the installation of entire die on automation equipment simultaneously, said first alloy block and second alloy block are cuboid, the degree of depth of said groove is 4mm～6mm.
After adopting said structure, be characterized in: select the screw thread extrusion die for use by the studs specification, the screw thread processing teeth groove that alloy block is inboard is made amendment; Select the height of alloy block according to the length of studs, confirm the position that screw thread processing teeth groove need be revised by studs two head threads and the length of thick bar part again, respectively two screw threads processing teeth groove are carried out grinding or line cutting by fixed position; Process a groove; The degree of depth of groove and width decide according to the diameter and the length of the thick bar part of studs, and this structural design is applied on the automation equipment, two head thread one-shot formings; Interference is arranged when having avoided the middle thick bar position of studs to one-shot forming; Improved production efficiency simultaneously, the profile of cuboid is of value to installation, makes convenience quick for installation.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the sketch map of the utility model;
Fig. 2 is the sketch map of studs.
Among the figure: 1, first alloy block 2, second alloy block 3, first screw thread processing teeth groove 4, groove 5, second screw thread processing teeth groove 6, studs.
The specific embodiment
A kind of studs extrusion die shown in Figure 1; Main body is first alloy block 1 and second alloy block 2; Offer first screw thread processing teeth groove 3 and second screw thread processing teeth groove 5 in the inboard of first alloy block 1 and second alloy block 2 up and down respectively, offer a groove 4 between said first screw thread processing teeth groove 3 and second screw thread processing teeth groove 5; Said first alloy block 1 and second alloy block 2 are cuboid, and the degree of depth of groove 4 is 4mm～6mm.
Select the screw thread extrusion die for use by studs 6 specifications; First alloy block 1 and second alloy block, 2 inboard first screw thread processing teeth groove 3 and second screw thread processing teeth groove 5 are made amendment; Select the height of first screw thread processing teeth groove 3 and second screw thread processing teeth groove 5 according to the length of studs 6, confirm the position that screw thread processing teeth groove need be revised by the 6 liang of head threads of studs and the length of thick bar part again, respectively two teeth groove are carried out grinding by fixed position or line cuts; Process a groove 4; The degree of depth of groove 4 and width decide according to the diameter and the length of the thick bar part of studs, and this structural design is applied on the automation equipment, two head thread one-shot formings; Interference is arranged when having avoided studs 6 middle thick bar positions to one-shot forming; Improved production efficiency simultaneously, the profile of cuboid is of value to installation, makes convenience quick for installation.
