Description

Technical Field

[0001] The utility model relates to the technical field of pipe welding equipment, in particular to a programmable control pipe welding equipment. Background Art

[0002] Welded steel pipe, also known as welded pipe, is a steel pipe made by welding steel plates or strips after curling and forming, and is generally fixed in length of 6 meters. The production process of welded steel pipe is simple, the production efficiency is high, there are many varieties and specifications, and the equipment investment is small, but the general strength is lower than that of seamless steel pipe. When the welded pipe is used in the fields of transporting gas and liquid, it is required to have good sealing performance. After the welding of stainless steel welded pipe is completed, the weld surface needs to be polished and ground. The stainless steel welded pipe needs to be fixed during the grinding. After the current fixing device fixes the stainless steel welded pipe, the staff polishes and grinds its surface with a handheld grinder. After grinding, the stainless steel welded pipe needs to be rotated continuously to fully grind its surface.

[0003] After searching, the Chinese patent announcement number is CN219444059U, which discloses a stainless steel welded pipe fixing device. In this patent, the distance between the first fixing plate and the second fixing plate can be changed by setting a connecting rod, a sliding block and a second fixing plate on the base, thereby increasing the fixing range of the stainless steel welded pipe, and then the second fixing plate is fixed to the base by the locking bolts on the fixing frame, and the stainless steel welded pipe is inserted into the first fixing ring and the second fixing ring, and the bidirectional screw rod is rotated to drive the first extrusion plate and the second extrusion plate to approach each other, so as to clamp and fix the stainless steel welded pipe, so that the stainless steel welded pipe is located in the middle of the first fixing ring, and at the same time, the waste collection device such as the feed hopper is moved to the right below the steel pipe welding part by moving the mounting block, so as to collect the waste generated by the surface grinding of the steel pipe welding part;

[0004] However, because the left and right lengths of the weld on the steel pipe surface are not necessarily equal, and one side of the fixed plate in the above device cannot move, the waste collection device may not be able to effectively collect the waste generated by grinding the weld, and the bidirectional screw rod and the first extrusion plate and the second extrusion plate have poor fixing effect on the steel pipe. Utility Model Content

[0005] The utility model provides a programmable control pipe welding device, which has the advantages of quickly fixing steel pipes of unequal lengths on the left and right sides of a welding point, and is convenient for collecting waste generated by grinding at the welding point. It solves the problem in the related art that steel pipes of different lengths on the left and right sides of a welding point cannot be effectively fixed and waste generated by grinding at the welding point is difficult to effectively collect.

[0006] The technical scheme of the utility model is as follows: a programmable control welding pipe equipment comprises a workbench, wherein slide grooves are provided on the left and right sides of the workbench, a front rotating rod is rotatably installed on the front side of the inner cavity of the left slide groove, a rear rotating rod is rotatably installed on the rear side of the left slide groove, a limiting hole is provided on the front side of the rear rotating rod, a round frame is fixedly installed on the rear side of the rear rotating rod and the front side of the front rotating rod, a round rod is movably installed on the middle part of the front rotating rod, a rotating plate is fixedly installed on the front side of the round rod, a limiting rod is fixedly installed on the rear side of the round rod, and sliders are movably installed on the outer surfaces of the front rotating rod and the rear rotating rod.

[0008] Preferably, the cross-section of the inner cavity of the limiting hole is of polygonal design, and the shape and length of the inner cavity of the limiting hole match the shape and length of the outer surface of the limiting rod. Therefore, when in use, after the front rotating rod extends the limiting rod into the inner cavity of the limiting hole on the front side of the rear rotating rod through the round rod, the front rotating rod and the rear rotating rod are integrated into one, and then when the front or rear round frame is rotated, the front rotating rod and the rear rotating rod can be driven to rotate synchronously.

[0009] Preferably, the outer surface of the front rotating rod is provided with a thread matching the inner wall of the connection with the front slider, and the outer surface of the rear rotating rod is provided with a thread matching the inner wall of the connection with the rear slider. The outer surfaces of the front rotating rod and the rear rotating rod are provided with threads in opposite directions, so that when in use, the front rotating rod and the rear rotating rod rotate synchronously, which can simultaneously drive the front or rear slider to move closer to or away from the center of the workbench synchronously.

[0010] Preferably, the diameter of the arc block matches the diameter of the inner cavity of the annular groove, and the ring is movably mounted on the top of the vertical rod through the annular groove and the arc block, so that the ring can rotate on the top of the vertical rod when in use.

[0011] Preferably, the shape and distribution position of the rack match the shape of the outer surface of the gear, and the gear is detachably mounted on the output shaft at the front side of the motor.

[0012] Preferably, the switch is electrically connected to the control block and the electromagnet through a wire. After power is turned on, the electromagnet and the arc plate on the top of the upper rubber block for connection have the same magnetic pole. When in use, the switch is pressed and the electromagnet is powered on, causing the upper rubber block to move downward and cooperate with the lower rubber block to fix welded steel pipes of different shapes.

[0013] Preferably, the discharge trough is located in the middle of the workbench, and the discharge trough is located in the middle of the left and right sliders. The length of the top of the inner cavity of the discharge trough is greater than the diameter of the circular ring. Therefore, when in use, the position and shape of the discharge trough can be utilized to effectively collect the debris generated by grinding when grinding the welding point of the welded pipe.

[0014] The working principle and beneficial effects of the utility model are:

[0015] The programmable control pipe welding equipment is used in conjunction with a round rod structure and a limit rod structure. When in use, the limit rod is extended into the inner cavity of the limit hole, so that the front rotating rod and the rear rotating rod are connected as one body, and then the rotation of one side of the round frame can drive the front and rear sliders to move forward or backward synchronously. When it is necessary to clamp steel pipes with different front and rear lengths at the welding point, the round rod is moved forward through the rotating plate to separate the limit rod from the limit hole. At this time, the front rotating rod and the rear rotating rod can only adjust the position of the front or rear slider separately, which is convenient for fixing steel pipes with different front and rear lengths at the welding point.

[0016] The programmable control pipe welding equipment is used in conjunction with an upper rubber block structure and a control block structure. When in use, a switch starts the electromagnet to energize, causing the upper rubber block to move downward, and cooperate with the lower rubber block to fix the front and rear ends of the steel pipe. At the same time, the welding point is located directly above the discharge chute, and the motor is started after the steel pipe is fixed, so that the front and rear rings rotate during operation, thereby continuously and comprehensively grinding the welding point of the steel pipe and utilizing the position of the welding point to facilitate the collection of waste generated by grinding.
