Description

Ventilation structure for laser cutting machine tool body

Technical Field

The utility model relates to a laser cutting equipment technical field specifically is a ventilation structure for laser cutting machine lathe bed.

Background

With the development of industries such as sports equipment, mechanical hardware, steel structure construction and the like, various plate processing becomes more and more common. The traditional plate cutting method is gradually replaced by a laser cutting technology due to the defects of low efficiency, low precision, high energy consumption, easy deformation of workpieces and the like. The laser cutting technology is widely applied to various fields due to the characteristics of high quality, high precision, high efficiency and low energy consumption. Generally, laser cutting apparatuses are constructed in a table type, i.e., a table type laser cutting machine, and smoke generated during cutting is discharged through an air duct. In the ventilation structure of the existing laser cutting machine, the areas of the ventilation openings at any positions of the upper end of the hopper are the same, so that one side far away from the air draft equipment is caused, the air draft effect is not ideal, and the air draft is not uniform; the vent still is the entry of hot sediment simultaneously, causes very easily that hot sediment gets into the vent and forms the jam, needs frequent clearance, not only influences the convulsions effect, and the maintenance is also inconvenient.

SUMMERY OF THE UTILITY MODEL

In view of the not enough and defect that exists among the prior art, the utility model provides a ventilation structure for laser cutting machine lathe bed, simple structure, and can solve the problem that convulsions smoke abatement effect is not good among the background art.

In order to solve the technical problem, the utility model discloses a following technical scheme: the utility model provides a ventilation structure for laser cutting machine lathe bed, includes air pipe, air pipe and cutting machine lathe bed fixed connection, the air pipe level is arranged the workstation below of lathe bed to run through all cutting machine unloading funnels, at every the inside air pipe's of unloading funnel intermediate position department is provided with the vent, air pipe right-hand member opening is connected with outside air drafting equipment, and the left end is sealed, the vent includes a plurality of rectangle rectangular holes, every the area inequality of the vent that sets up in the unloading funnel, every promptly the quantity in the rectangle rectangular hole that sets up is different in the unloading funnel.

As a further improvement of the utility model, air pipe is square pipe, the vent sets up on the face of both ends around square pipe, the orientation place plane of vent is parallel with workstation place plane.

As a further improvement, the right side in the unloading funnel the quantity in rectangle rectangular hole is less than the quantity in rectangle rectangular hole in the unloading funnel in left side, keeps away from promptly one side of air extraction equipment, the quantity in rectangle rectangular hole is more.

As a further improvement, the utility model is two adjacent in the unloading funnel the quantity in rectangle rectangular hole is compared, and the quantity on left side more than the right side is two.

Compared with the prior art, the utility model discloses the beneficial effect who has does: the utility model discloses a set up air pipe in the lathe bed to set up the vent at air pipe, the open area of vent keeps away from the bigger mode of air extraction equipment more, and dust removal smoke exhaust effect is best, remains air pipe's noncongestion throughout. Air pipe one end is connected with external air extraction equipment, and the other end seals, forms the negative pressure through convulsions, discharges smoke and dust and heat through air pipe, and the orientation place plane of vent is parallel with workstation place plane, and the produced hot sediment of cutting is vertical under the action of gravity like this drops, just so can avoid with hot sediment inspiration rectangular pipe.

Detailed Description

In order to make the technical solution and the advantages of the present invention more clear and more obvious, the present invention is further described in detail with reference to the accompanying drawings and the specific embodiments, it should be understood that the specific embodiments described herein are only used for understanding the present invention, and are not used for limiting the present invention, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention.

As shown in figures 1-3, the utility model provides a ventilation structure for laser cutting machine bed, including air pipe 3, air pipe 3 and cutting machine bed 1 fixed connection, air pipe 3 level is arranged in the workstation below of bed 1, and run through all cutting machine unloading funnels 2, the intermediate position department of air pipe 3 inside each unloading funnel 2 is provided with vent 4, air pipe 3 right-hand member opening is connected with outside air extraction equipment, the left end is sealed, vent 4 includes a plurality of rectangle rectangular holes 401, the area of vent 4 that sets up in each unloading funnel 2 is all inequality, namely every the quantity of rectangle rectangular hole 401 that sets up in unloading funnel 2 is different, smoke and dust and hot-air enter air pipe through the vent, be dispatched at last, reach the effect of dust removal and cooling, the lower extreme communicates with the external world, when the air draft equipment works, negative pressure is formed in the space below the bed body, and cold air is automatically sucked from the underground, so that the aim of further cooling is fulfilled.

Preferably, air pipe 3 is square pipe, and vent 4 sets up on the front and back both ends face of square pipe, and the orientation place plane of vent 4 is parallel with workstation place plane, and the produced hot sediment of cutting just so can avoid inhaling the hot sediment in the rectangular pipe under the action of gravity vertical drop.

Preferably, the number of the rectangular strip holes 401 in the right discharging funnel is less than that of the rectangular strip holes 401 in the left discharging funnel, namely, the farther away from one side of the air draft equipment, the more the number of the rectangular strip holes 401 is, the more the number of the rectangular strip holes in two adjacent discharging funnels is compared, and the number of the left side is two more than that of the right side.

According to the laser instrument power difference, to 3000W as an example, adopt 7 rectangle rectangular holes near the air extraction equipment direction, keep away from the air extraction equipment direction and increase 2 rectangle rectangular holes in proper order, because it is big more to be close to air extraction equipment department wind-force more, it is little more to keep away from air extraction equipment department wind-force more, in order to reach the same dust absorption, the area that the less department of wind-force need increase the vent, just such setting can reach the vent of keeping away from air extraction equipment and have fine dust absorption effect equally.
