Abstract
The utility model belongs to the field of copper material processing, and particularly relates to a deep-trench extrusion wheel. An annular trench for feeding a rod into an extrusion wheel is formed in the circumference of the extrusion wheel, and is 22.5mm+/-5dmm deep and wide. The deep-trench extrusion wheel has the beneficial effects that hanging copper is arranged at the trench of the extrusion wheel, and the trench of the extrusion wheel is deepened and widened by 50+/-5dmm, so that the thickness of the hanging copper is increased, the firmness of the hanging copper is improved, safety for the reduction of a gap between a die cavity and the extrusion wheel is ensured, extrusion overflow is controlled between 40 to 50dmm, the overflow rate after improvement is reduced from original 10 percent to 6 percent, stable passing operation is ensured, 200 tons of overflow can be annually reduced based on the yield of 5,000 tons of copper bars to form a price difference of 3,000 yuan per ton, and 600,000 yuan can be reduced in the whole year.
Description
(1) technical field
The utility model belongs to copper material manufacture field, particularly a kind of quirk squeegee roller.
(2) background technology
The continuous extrusion production of copper material is the new technology occurring in the world nineteen nineties, and its adopts copper wire rod that up-drawing method produces as blank (hereinafter referred to as bar material), under the driving of squeegee roller, by the continuously extruded product that goes out all size of mould.Due to adopt continuously extruded technology produce copper material have energy-conservation, production efficiency is high, any surface finish is low without burr, resistivity, be easy to guarantee the plurality of advantages such as resistance balance, mechanical strength height, therefore obtained development very soon, but the situation that very easily occurs flash, cause very large waste, need to improve.
(3) summary of the invention
The utility model is in order to make up the deficiencies in the prior art, and a kind of flash, quirk squeegee roller easy to use of reducing is provided.
The utility model is achieved by the following technical solution:
A squeegee roller, is provided for the ring-shaped groove that bar material feeds squeegee roller inside on the circumference of squeegee roller, its special character is: gash depth, width are 22.5 millimeters ± 5.
Quirk squeegee roller of the present utility model, squeegee roller is communicated with die cavity, and the mould of bar material being made to copper strap wire is set in die cavity, the pad of installation in die cavity, the gap of die cavity and squeegee roller is 40 to 50.
The beneficial effects of the utility model are: there is coppering at the groove place of squeegee roller, the utility model is by widening 50 ± 5 to squeegee roller groove, coppering thickness and firmness thereof have been increased, this is for reducing die cavity and squeegee roller gap provides safety guarantee, and guarantee that extruding flash is controlled between 40 ~ 50, after transformation, flash rate is down to 6% by original 10%, very stable by operation, annual by producing 5000 tons of copper bars calculating, can lack 200 tons of flashes, 3000 yuan of price differences per ton, can save 600,000 yuan of funds the whole year.
(4) accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further described.
Accompanying drawing 1 is structural representation of the present utility model;
In figure, 1 squeegee roller, 2 bar material, 3 grooves, 4 die cavitys, 5 copper strap wires, 6 moulds.
(5) specific embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises squeegee roller 1, squeegee roller 1 is communicated with die cavity 4 and is used in conjunction with guide plate, the interior mould 6 of bar material 2 being made to copper strap wire 5 that arranges of die cavity 4, on the circumference of squeegee roller 1, there is a ring-shaped groove 3, bar material 2 ring-shaped groove 3 feedings thus, the boots seat that feeding guide-plate and die cavity 4 are housed closes and compresses, groove 3 degree of depth are 22.5 millimeters ± 5, the degree of depth of former groove 3, width is 22 millimeters, often there is copper layer obscission, the effective means addressing this problem is: by being placed in coppering between the two, reduce die cavity 4 and squeegee roller 1 gap, and the coppering of original device is thinner, fastness is inadequate, easily come off, gap between die cavity 4 and squeegee roller 1 is 60 to 70, the utility model is widened 50 ± 5 by the groove 3 to squeegee roller 1, make like this copper layer thickness in the groove 3 of squeegee roller 1 increase by 50, increased the firmness of copper layer, simultaneously, there are 13 to change 1 on the pad of cavity, gross thickness is constant, this provides safety guarantee to make its gap become 40 to 50 for reducing die cavity 4 with squeegee roller 1 gap, and guarantee that extruding flash is controlled between 40 ~ 50, after transformation, flash rate is down to 6% by original 10%, very stable by operation, annual by producing 5000 tons of copper bars calculating, can lack 200 tons of flashes, 3000 yuan of price differences per ton, can save 600,000 yuan of funds the whole year.
Claims (2)
1. a quirk squeegee roller, comprises squeegee roller (1), is provided for the inner ring-shaped groove (3) of bar material (2) feeding squeegee roller (1) on the circumference of squeegee roller (1), it is characterized in that: groove (3) degree of depth, width are 22.5 millimeters ± 5.
2. quirk squeegee roller according to claim 1, it is characterized in that: squeegee roller (1) is communicated with die cavity (4), the mould (6) of bar material (2) being made to copper strap wire (5) is set in die cavity (4), the pad of installation in die cavity, the gap of die cavity and squeegee roller is 40 to 50.
