A steel pipe end protector discharge guide device

Abstract

The invention discloses an improved discharging guide device for a steel pipe end protector. The guide device is divided into three parts. One part is a 120° large inclined surface designed upward on the cutting plane according to the motion trajectory of the discharging workpiece. The vertical surface is inclined by 30° to ensure that the material can automatically fall according to the gravity direction. Another part is a triangular plane rooted and welded at the lower end of the large inclined surface. The triangular plane forms an angle of 20° with the large inclined surface. The purpose is to guide the workpiece to be staggered with the blade when the workpiece is cut and leaves the inertia of the upper blade upward, and fall obliquely. Another part is a circular arc material drop trough arranged below the triangular plane. The workpiece is guided by the large inclined surface and the triangular plane in turn to fall into the circular arc material drop trough.

Description

Technical Field

[0001] The invention relates to a discharging guide device for a steel pipe end protector, which belongs to a modified discharging device for a steel pipe end protector. Background Art

[0002] The pipe end protector is a steel ring installed at both ends of the steel pipe. It is used to protect the steel pipe groove surface during lifting and hoisting to avoid hanging the groove surface. It is a commonly used pipe end protection tool for oil and gas steel pipes. The equipment for making pipe end protectors has developed rapidly in recent years, and the degree of automation is getting higher and higher. At present, multi-roll forming is adopted. The raw materials are placed in the material tray, and the circumference is input in the control interface to automatically roll the pipe. After the length is reached, the pipe is automatically cut. The bolts and nuts are assembled manually, welded on the pipe end protector ring, and the middle nut is adjusted and installed on the inside of the steel pipe. The degree of automation of the pipe end protector manufacturing equipment has been improved, but the equipment safety is poor and cannot meet the safety requirements. Further improvement is needed. The main problem is that after automatic cutting, the material cannot be dropped safely, and the operator needs to hold the hook to pick up the materials one by one, otherwise each material will fall together and be cut to cause waste. Summary of the invention

[0003] The purpose of the present invention is to provide a material discharging guide device for a steel pipe end protector. After cutting the material, an inclined material dropping guide device and a temporary material storage area are designed to achieve the purpose of automatically dropping the material into a basket. Personnel no longer come into contact with moving objects, ensuring safety.

[0004] The technical solution adopted by the present invention is a discharge guide device for a steel pipe end protector, which is divided into three parts. One part is a 120° large inclined surface designed upward on the cutting plane according to the motion trajectory of the discharged workpiece, and the vertical surface is inclined at 30° to ensure that the material can automatically fall according to the direction of gravity. One part is a triangular plane rooted and welded at the lower end of the large inclined surface. The triangular plane and the large inclined surface form an angle of 20°. The purpose is to guide the workpiece to be staggered with the blade when the workpiece is cut and leaves the inertia of the upper blade upward, and fall obliquely. One part is an arc drop trough arranged below the triangular plane, and the workpiece is guided by the large inclined surface and the triangular plane in turn to fall into the arc drop trough.

[0005] Through observation, it was found that the movement trajectory of the pipe end protector after rolling has no guide, and people can only use hooks to guide the falling of materials. By utilizing the principle that materials can fall by themselves in the direction of gravity when tilted more than 30°, the design of a guide device can solve the problem of automatic falling of materials into the basket. The present invention avoids contact with the material coming up from below. After the second pipe end protector is rolled out and cut off, the first pipe end protector is automatically pushed out and falls into the ground basket. The shape of the falling trough is semicircular arc, with a maximum depth of 300mm. Two to three materials can be temporarily stored, realizing unattended and automatic production. After the improvement, the operator no longer uses a hook to hook the workpiece when the workpiece rotates, and the safety red line prohibition of not touching any part of the person's body and not contacting moving objects ensures the safety of personnel. At the same time, automatic falling of materials is realized, one operator is reduced, and cost reduction and efficiency improvement are achieved. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] A steel pipe end protector discharge guide device, such as Figure 1-5 As shown, the guide device is divided into three parts. One part is a 120° large inclined plane 1 designed upward on the cutting plane according to the motion trajectory of the discharged workpiece, and the vertical plane is inclined at 30° to ensure that the material can automatically fall according to the direction of gravity. One part is a triangular plane 2 rooted and welded at the lower end of the large inclined plane 1. The triangular plane 2 forms an angle of 20° or 160° with the large inclined plane 1. The purpose is to guide the workpiece to be staggered with the blade when the workpiece is cut and leaves the upper blade 4 upward by inertia, and fall obliquely. One part is a circular arc drop trough 3 set below the triangular plane 2. After the workpiece comes out from the cutting edge of the upper and lower blades 4 and 5, it is guided by the large inclined plane 1 and the triangular plane 2 in turn and falls into the circular arc drop trough 3. When working, the pipe end protector rolls out from the bottom through the inclined surface guide of the large inclined plane 1 and the triangular plane 2, enters the circular arc drop trough 3, and is pushed out of the drop trough 3 and enters the material basket after one or two.

[0013] The present invention avoids the contact between the processed workpiece and the material coming up from below. After the second pipe end protector is rolled out and cut off, the first pipe end protector is automatically pushed out and falls into the ground drop basket. The drop trough 3 is in the shape of a semicircular arc, with a maximum depth of 300mm, and can temporarily store two to three materials, realizing unattended and automatic production. After the improvement, the operator no longer uses a hook to hook the workpiece when the workpiece rotates, and the safety red line prohibition of not touching any part of the human body and not contacting the moving object is guaranteed, which ensures the safety of the personnel.
