Abstract

A steel tube blank tail cushion conveyer between a heating furnace and an extrusion container comprises a tail cushion heating furnace and an active V-shaped extrusion cushion conveying chute. A U-shaped chute with the width matching with the thickness of the tail cushion is arranged below the discharge door of the tail cushion heating furnace; a discharge shedding plate is arranged between the lower edge of the discharge door of the heating furnace and the upper end of the U-shaped chute, which is close to the upper edge of a side plate; a downward elbow bend and a tube sinking which matches with the radially vertical tail cushion are arranged at the lower end of the U-shaped chute; the tube sinking faces the active V-shaped extrusion cushion conveying chute below; a spring hinge baffle is installed at the front external side face of the tube sinking to prevent the tail cushion from overturning when the tail cushion falls down. The steel tube blank tail cushion conveyer is simple in structure and the connection transition is smooth and reliable; The steel tube blank tail cushion conveyer effectively solves the problems in turning the horizontal tail cushion of the heating furnace to be vertical in the radial direction and smoothly conveying the radially vertical tail cushion to the active V-shaped extrusion cushion conveying chute, and no external motive power is needed during the conveying process; therefore the steel tube blank tail cushion conveyer is low in energy consumption and low in cost.

Description

Heating furnace is to the steel tube blank tail pad conveyer between the recipient

Technical field

The utility model relates to a kind of material transport device in the steel pipe hot extrusion production technique process.

Background technology

Being hot extruded into shape steel tube is one of ripe at present steel pipe's production mode, and particularly high value stainless steel, the alloy pipe that high-quality, high request, special industry are used all adopts this method to produce basically.The process unit that is hot extruded into shape steel tube generally is by recipient, be installed on the extrusion die of recipient leading section, pack into successively the glass lubricating pad, steel tube blank, the dummy block that offer centre bore in the recipient are pressed on the dummy block rear end face, the pressure ram that the plug that can pass dummy block, steel tube blank, glass lubricating pad and extrusion die centre bore is housed of wherein feeling at ease forms.Be hot extruded into shape steel tube with this process unit, its steel tube blank always has a bit of remaining in can not be extruded in the recipient and become " pressing surplus waste material " at last, and this presses surplus waste material generally to account for 5～8% of steel tube blank, thereby causes the very big waste of expensive raw materials.For this reason, the applicant has invented a kind of " hot extrusion steel tube blank tail pad " (patent applied for), promptly adopt inexpensive common iron make a joint consistent with the interior external diameter of alloy pipe blank and length is equivalent to the tail pad of " pressing surplus waste material ", be connected end in extrusion billet, thereby make expensive alloy pipe blank be squeezed into steel pipe fully, the tail pad finally becomes " pressing surplus waste material ".In order to implement this technology, obviously, also must design the conveying corollary apparatus that blank tail pad after blank tail pad machine-shaping → be delivered to heating furnace → heating is sent to the recipient process.

Summary of the invention

The purpose of this utility model provides the conveyer that a kind of steel tube blank tail pad with heating furnace output is sent to recipient.

Because steel tube blank tail pad finally will be sent to V-shaped dummy block activity and pick on the device, and place the dummy block front, there is the recipient feeder of the steel tube blank of axial horizontal positioned to connect with acceptance then, dummy block is pushed in the recipient feeder with the tail pad is connected mutually with steel tube blank, so that push in the recipient together, therefore the pipe nipple tubular tail pad that requires former radial level to be placed in to heat in the heating furnace converts to after coming out of the stove radially to be erect shape and transmits, with convenient matched with dummy block and steel tube blank, for this reason, art designs scheme of the present utility model is: device comprises that tail pad heating furnace and V-shaped dummy block activity pick groove, its tail pad heating furnace discharging fire door below is equipped with groove width and the suitable U-shaped chute of tail mat thickness, be connected with blanking between bead and the limit, neighbour's side plate upper edge, U-shaped chute upper end under the heating furnace discharge door and drop down plate, U-shaped chute bottom is provided with downward elbow bend, the elbow bend outlet is made and the radially suitable reducing of tail pad of upright state, this reducing is picked groove at the V-shaped dummy block activity of its below, and the laterally perpendicular of groove picked in the vertical and V-shaped dummy block activity of reducing, and the Spring hinge baffle plate of toppling over when anti-tail pad falls is installed on the reducing anterolateral surface.

The utility model apparatus structure is simple, it is steadily reliable to connect transition, having solved the tail pad that the radial level state is gone out heating furnace effectively is converted to upright state radially and keeps upright state to be sent to the dummy block activity reposefully and pick a difficult problem in the groove, and do not need additionaling power in this device transport process, energy consumption and production cost are low.

Description of drawings

Accompanying drawing is the utility model perspective view.

The specific embodiment

The utility model is described in further detail with embodiment below in conjunction with accompanying drawing.

U-shaped chute 5 is installed on the below of tail pad heating furnace 1, the thickness of its groove width and tail pad 2 is suitable, be connected with blanking between bead and the limit, neighbour's side plate upper edge, U-shaped chute 5 upper end under the discharge door of heating furnace 1 and drop down plate 4, U-shaped chute 5 bottoms are provided with downward elbow bend 6, elbow bend 6 outlet is made and the suitable reducing 9 of the tail pad 2 of upright state radially, this reducing 9 is picked V-shaped groove 10 at the dummy block activity that pushes oil cylinder 7 that has of its below, and the laterally perpendicular of V-shaped groove 10 picked in the vertical and dummy block activity of reducing 9, and the Spring hinge baffle plate 11 of toppling over when anti-tail pad 2 falls is installed on reducing 9 anterolateral surfaces.

This device course of work is, radial level places the tail pad 2 of heating on the heating furnace burner hearth guide rail 3, be pushed out the discharge door of heating furnace 1 after the heating, drop down plate 4 landings to U-shaped chute 5 along discharging, be that nature is radially upright state and rolls along chute, meanwhile, thereafter V-shaped groove 10 is picked in the end dummy block activity that undertakes dummy block 8 the sixth of the twelve Earthly Branches, under the effect of its trailing arm 12 and hoist cylinder 15 thereof, rise near chute elbow reducing 9 places, when tail pad 2 is rolled into the chute elbow through reducing 9 vertical drops, just in time dropping on the dummy block activity picks on the V-shaped groove 10, and its upper lateral part is blocked by the Spring hinge baffle plate 11 of reducing 9 sides and keeps radially upright state, the recipient feeder 14 that undertaken steel tube blank 13 this moment also under the effect of its transmission arm 17 and transmission oil cylinder 16 thereof elevate a turnable ladder pick V-shaped groove 10 with the dummy block activity and dock, pick in the dummy block activity under the promotion of V-shaped groove 10 rear portion oil cylinders 7, dummy block 8 is transferred on the recipient feeder 14 with tail pad 2 and is engaged togather with steel tube blank 13.
