Description
Technical field
The utility model relates to solid guide rail processing technique field, particularly a kind of mine solid guide rail shape extrusion device.
Background technology
Mine solid guide rail is that end face entirety is U-shaped, and corner is leg-of-mutton guide rail.Solid guide rail comprises the base wall that two studs and two ends are connected with two studs respectively, and its insole binding wall is solid part.Wherein solid guide rail shape extrusion device is used for the shaping of solid guide rail.
Traditional solid guide rail shape extrusion device comprises upper die and lower die and work strip, and work strip is arranged on the import department of patrix, and work strip is provided with the inlet opening for matching with diffluence pass edge on patrix.But, because the thickness at solid guide rail section bar stud two ends leg and wall place, base is more than 42mm, and wall thickness stud connecting the middle part of two ends leg only has 10mm, the overall wall thickness of solid guide rail differs greatly, when solid guide rail is extruded, in inlet opening with stud in the middle part of the flow rate of metal of just right the first tap hole in position very fast, and it is slower with the flow rate of metal of the leg of stud and just right the second tap hole of base wall in inlet opening, in extruded process, flow rate of metal difference is excessive, turn round after causing solid guide rail to go out nib and twist or bend, make the Forming Quality of solid guide rail poor.
Therefore, how reducing because in extrusion process, flow rate of metal difference is excessive, cause the situation that the Forming Quality of solid guide rail is poor, is those skilled in the art's technical problems urgently to be resolved hurrily.
Utility model content
The purpose of this utility model is to provide a kind of mine solid guide rail shape extrusion device, to reduce because in extrusion process, flow rate of metal difference is excessive, causes the situation that the Forming Quality of solid guide rail is poor.
For achieving the above object, the utility model provides a kind of mine solid guide rail shape extrusion device, comprise upper die and lower die and work strip, described work strip is arranged on the import department of described patrix, described work strip is provided with the inlet opening with the inlet communication of described patrix, on described inlet opening with stud in the middle part of just right the first tap hole in position be outer reaming.
Preferably, described inlet opening is provided with obstruction block with the exit of the leg of stud and just right the second tap hole of base wall.
Preferably, described obstruction block welding is in described work strip.
Preferably, the alignment pin for locating described patrix and described counterdie is also comprised.
Preferably, described patrix and described counterdie are equipped with the blind hole of accommodating described alignment pin.
Preferably, described patrix is connected by dormant bolt with described counterdie.
Preferably, the head of described dormant bolt is positioned on described counterdie.
In technique scheme, the mine solid guide rail shape extrusion device that the utility model provides comprises upper die and lower die and work strip, work strip is arranged on the import department of patrix, work strip is provided with the inlet opening with the inlet communication of patrix, on inlet opening with stud in the middle part of just right the first tap hole in position be outer reaming.
Known by foregoing description, in the mine solid guide rail shape extrusion device that the utility model provides, because the first tap hole that position in the middle part of inlet opening and stud is just right is outer reaming, expand this place's liquid chamber circulation area, and then the feed liquor speed reduced in the middle part of solid guide rail stud, avoid flow rate of metal difference in extrusion process excessive, cause the situation that the Forming Quality of solid guide rail is poor.
Accompanying drawing explanation
The structural representation of the work strip of the solid guide rail shape extrusion device that Fig. 1 provides for the utility model embodiment.
Wherein in Fig. 1: 1-work strip, 2-inlet opening, 3-second tap hole, 4-first tap hole.
Detailed description of the invention
Core of the present utility model is to provide a kind of mine solid guide rail shape extrusion device, to reduce because in extrusion process, flow rate of metal difference is excessive, causes the situation that the Forming Quality of solid guide rail is poor.
In order to make those skilled in the art understand the technical solution of the utility model better, below in conjunction with drawings and embodiments, the utility model is described in further detail.
Please refer to Fig. 1, in a kind of detailed description of the invention, the mine solid guide rail shape extrusion device that the utility model provides comprises upper die and lower die and work strip 1, during solid guide rail shape extrusion device busy, upper die and lower die are fixed by snap, work strip 1 is arranged on the import department of patrix, work strip 1 is provided with the inlet opening 2 with the inlet communication of patrix, on inlet opening 2 with stud in the middle part of just right the first tap hole 4 in position be outer reaming, namely the first tap hole 4 increases gradually along the liquid direction of motion.
Known by foregoing description, in the mine solid guide rail shape extrusion device that the utility model specific embodiment provides, first tap hole 4 just right due to position in the middle part of inlet opening 2 and stud is outer reaming, expand this place's liquid chamber circulation area, and then the feed liquor speed reduced in the middle part of solid guide rail stud, avoid flow rate of metal difference in extrusion process excessive, cause the situation that the Forming Quality of solid guide rail is poor.
Further, inlet opening 2 is provided with obstruction block with the exit of the leg of stud and just right the second tap hole 3 of base wall, concrete, hinder block can be bonded in work strip 1, in order to improve the bonding strength hindering block and work strip 1, preferably, block is hindered to weld with work strip 1.By arranging obstruction block, reduction metal enters the speed in patrix by the second tap hole 3, reduce flow rate of metal in extrusion process further poor, effectively improve the crudy of solid guide rail.
