DETAILED DESCRIPTION

[0020] Embodiment:

[0021] As Figure 1 and Figure 2 , the embodiment provides an automatic zinc removal device for a galvanized steel pipe end, which comprises an electromagnetic induction heater 1, a fixed feeding mechanism 2 and a movable feeding mechanism 3. The fixed feeding mechanism 2 comprises a roller driving motor 2a and a first claw lifting motor 2b. The roller driving motor 2a drives a set of driving rollers 2c. The first claw lifting motor 2b drives a set of first claws 2e through a first rotary rocker arm 2d. The movable feeding mechanism 3 comprises a second claw lifting motor 3a and a set of driven rollers 3b. The second claw lifting motor 3a drives a set of second claws 3d through a second rotary rocker arm 3c.

[0022] The electromagnetic induction heater 1 is provided with two zinc burning heating coils 4, which are in an arc structure.

[0023] The first claws 2e and the second claws 3d are positionally matched with the zinc burning heating coils 4.

[0024] The electromagnetic induction heater 1 is arranged on a bracket track 5 at the bottom and is driven by a gas cylinder.

[0025] The movable feeding mechanism 3 is provided with rollers 6 at the bottom and a guide rail 7 at the bottom, which is used for controlling the distance between the movable feeding mechanism and the fixed feeding mechanism 2.

[0026] The fixed feeding mechanism 2 comprises a mounting seat 2f. The driving rollers 2c are horizontally arranged and mounted above the mounting seat 2f. The mounting seat 2f is provided with a gear set 2g at the side. The driving rollers 2c are driven by the gear set 2g through a rack transmission. The roller driving motor 2a drives the gear set 2g through a rack transmission.

[0027] The mounting seat 2f is further provided with a set of rocker gear 2h at the side. The first rotary rocker arm 2d is driven by the rocker gear 2h through a rack transmission. The first claw lifting motor 2b is connected to the rocker gear 2h through a rack transmission.

[0028] The rocker gear 2h has two, each of which is connected to a first rotary rocker arm 2d. Each first rotary rocker arm 2d is connected to a first claw 2e. Each first claw 2e is provided with two grooves 2i at the top for supporting the steel pipe.

[0029] The second claws 3d are positionally matched with the first claws 2e.

[0030] The fixed feeding mechanism of the embodiment is provided with one more roller driving motor than the movable feeding mechanism. The rest of the structure is the same. The electromagnetic induction heater 1 and the movable feeding mechanism 3 are arranged on the two sides of the fixed feeding mechanism 2. The zinc burning heating coil 4 is located above the gap between the two rollers on the right side of the discharging side. This position is a work station.

[0031] As Figure 3 , in use, before feeding, the electromagnetic induction heater 1 with the zinc burning heating coil 4 is driven by the air cylinder to move to the far end away from the fixed feeding mechanism to prevent the zinc burning heating coil 4 from colliding and interfering with the feeding and discharging steel pipes.

[0032] The first material claw lifting motor 2b and the second material claw lifting motor 3a are synchronously operated to keep the first material claw 2e and the first material claw 3d synchronously moving with the upper end surfaces parallel.

[0033] The first rotating rocker arm 2d and the second rotating rocker 3c support the first material claw 2e and the first material claw 3d respectively.

[0034] After feeding, the electromagnetic induction heater 1 with the zinc burning heating coil 4 moves to the fixed feeding mechanism 2, the zinc burning heating coil 4 is close to the pipe end of the steel pipe to be processed, the heater and the roller driving motor 2a are started to heat the pipe end of the steel pipe in rotation.

[0035] The zinc burning heating coil 4 is in a semicircular shape, which can avoid the zinc melting and falling on the heating coil after the temperature rises, causing burning loss.

[0036] The device uses electromagnetic induction heating technology to heat the pipe end to the zinc layer melting and burning temperature, and reacts in the air to produce zinc oxide. After the removal is completed, the electromagnetic induction heater retreats along the axial direction to avoid the interference of the feeding and discharging of the steel pipe. The feeding and discharging mechanism lifts the feeding and discharging of the steel pipe. During the rotation of the discharging mechanism rocker arm, the processed material is lifted, and the material to be processed is also lifted, and the feeding and discharging are completed synchronously, saving process time.
