Abstract
The utility model relates to a punch assembly with an injection-rod cooling inner pipe. The punch assembly comprises a punch and the cooling inner pipe. One end of the cooling inner pipe enters into the punch from the tail portion of the punch. The top end of the portion of the cooling inner pipe in the punch is provided with a cooling water outlet, which is at a distance of 5-15 mm from the front end of the punch. Compared with the prior art, the punch of the utility model is more sufficiently cooled by cooling liquids via the cooling water outlet in the front end of the cooling inner pipe, thereby effectively enhancing the punch cooling effect and prolonging the service lifetime of the punch.
Description
Technical field
The utility model relates to a kind of punch-head assembly, especially relates to a kind of punch-head assembly of penetrating pipe in the bar cooling that has.
Background technology
All need use the ejaculation drift at present a lot of processing technologys, penetrate drift and generally be connected ejaculation bar front end, can produce heat because it moves back and forth, inside relies on water quench.Pipe is not ideal on cooling effect in the tradition cooling, can't make drift maintain lower temperature, thereby causes drift to reduce service life.
The utility model content
The purpose of the utility model is exactly for the defective that overcomes above-mentioned prior art existence the punch-head assembly of penetrating pipe in the bar cooling having of a kind of good cooling results to be provided.
The purpose of the utility model can realize through following technical scheme: a kind of punch-head assembly of penetrating pipe in the bar cooling that has; It is characterized in that; Comprise the interior pipe of drift and cooling; An end of pipe is stretched in the drift by the afterbody of drift in this cooling, manages the top of stretching into part in the drift in the cooling and is provided with the cooling delivery port, and this cooling delivery port is apart from punch 5-15mm.
Described cooling delivery port is apart from punch 15mm, and this cooling delivery port pipe face evenly has six rectangular channels vertically, forms the divisional plane of 6 five equilibriums, and 3 divisional planes at interval bend inwards and gather, and all the other 3 divisional planes outwards bend diffusion.
Described rectangular channel length is 6mm, and width is 1mm.
Described cooling delivery port is apart from punch 5mm, and the apopore that it is 3mm that this cooling delivery port front end face has a diameter evenly has 4 groups of apopores on the pipe face near front end face.
The apopore that it is 3mm that described 4 groups of apopores are provided with 3 diameters for every group is arranged hole interbody spacer 3-10mm vertically.
Described cooling delivery port is apart from punch 15mm, and this cooling delivery port front end face has diameter and the identical apopore of cooling inner tube diameter.
Compared with prior art, the utility model makes cooling fluid cool off drift more fully through the cooling delivery port of pipe front end in cooling off, and effectively improves the cooling effect of drift, prolongs the service life of drift.
Description of drawings
Fig. 1 is the structural representation of the utility model.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is elaborated.
Embodiment 1
As shown in Figure 1, a kind of punch-head assembly of penetrating pipe in the bar cooling that has, pipe 2 one ends stretch into from drift 1 tail end and stretch into drift 1 inside in the cooling; The tops that the interior pipe 2 of cooling stretches into part in the drift 2 are provided with cooling delivery port 21, cool off delivery port 21 apart from drift 1 front end face 15mm, even vertically six the long 6mm of its pipe face; The rectangular channel of wide 1mm; Form the divisional plane of 6 five equilibriums, 3 divisional planes at interval bend inwards and gather, and all the other 3 divisional planes outwards bend diffusion; Make the cooling fluid of ejection be umbrella, reach better cooling effect.
A kind of punch-head assembly of penetrating pipe in the bar cooling that has; Cooling delivery port 21 is apart from punch face 5mm, and the apopore that it is 3mm that its front end face has a diameter evenly has 4 groups of apopores on the pipe face near front end face; The apopore that every group is equipped with 3 diameters is 3mm; Arrange vertically, hole interbody spacer 3-10mm, all the other are with embodiment 1.
Embodiment 3
A kind of punch-head assembly of penetrating pipe in the bar cooling that has, the identical apopore of pipe 2 internal diameters in cooling delivery port 21 front end faces have diameter and cool off, all the other are with embodiment 1.
Embodiment 1-3 is carried out the cooling effect test respectively, drift is connected with connecting rod, connect cooling water, use the temperature of coal gas burning front end punch face of measurement in per 2 minutes and side, as shown in the table.
