Description

Technical Field

[0001] This utility model belongs to the field of steel pipe drilling, and in particular relates to an automatic loading and unloading steel pipe drilling device at both ends. Background Technology

[0002] In the steel pipe processing industry, drilling holes at both ends is a common process, widely used in construction, machinery manufacturing, pipeline engineering, and other industries. Currently, drilling at both ends of steel pipes mostly relies on traditional equipment, but existing equipment has limitations in terms of automated operation and synchronous processing.

[0003] Most equipment struggles to achieve integrated continuous feeding, positioning, drilling, and unloading of steel pipes, requiring multi-step operations that disrupt the processing flow and impact overall efficiency. Furthermore, when processing multiple steel pipes in batches, the positioning mechanisms of existing equipment often suffer from structural design limitations, making it difficult to ensure simultaneous and accurate drilling at multiple stations. This can lead to hole position deviations, affecting subsequent assembly quality. Utility Model Content

[0004] In view of the above problems, the purpose of this utility model is to provide an automatic steel pipe punching device at both ends, which aims to solve the problems of low processing efficiency of existing steel pipe punching devices and the easy occurrence of hole position deviation in order to ensure synchronous and accurate punching at multiple stations, which affects the subsequent assembly quality.

[0005] The present invention adopts the following technical solution:

[0019] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0020] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0021] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0022] Combination Figure 1-4As shown, the automatic loading and unloading steel pipe end punching device includes a machine base 1. The machine base 1 is sequentially provided with a pair of placement racks 2 and a pair of punching mechanisms. A pair of loading and unloading racks 3 are provided between the punching mechanisms. The loading and unloading racks 3 have three grooves 4 in the middle. A transfer component is provided on the machine base 1 opposite to the loading and unloading racks 3. The punching mechanism includes a fixed frame 5 slidably mounted on the machine base 1. A punching frame 6 is provided inside the fixed frame 5. A top plate 7 is provided on the punching frame 6 for sliding limit. A punching seat 8 is provided inside the punching frame 6. Three punching rods 9 are provided downward on the top plate 7. A punching cylinder 10 is provided on the top of the fixed frame 5. The drive shaft of the punching cylinder 10 is connected to the top plate 7. A push column 11 is provided on each of the grooves opposite to the punching seat 8. A cylinder seat 12 is provided on the back of the fixed frame 5. A sliding cylinder 13 is provided on the cylinder seat 12. The drive shaft of the sliding cylinder 13 is connected to the punching seat 8.

[0023] In this device, a pair of loading and unloading racks are provided between the drilling mechanisms. The loading and unloading racks are used to support and position the steel pipes during the drilling process. Three grooves are opened in the middle of the loading and unloading racks. The shape of the grooves is adapted to the shape of the steel pipes, which can stably place the steel pipes. The three grooves can hold three steel pipes at the same time, and three steel pipes can be processed at the same time, which greatly improves production efficiency.

[0024] In actual operation, the steel pipes to be processed are first placed on the placement rack. When the loading operation is required, the left and right sets of transfer components can transfer three steel pipes to the loading and unloading racks at one time, and the two ends of the steel pipes fall into the grooves of the loading and unloading racks on the same side to complete the loading.

[0025] After the steel pipes are placed in the grooves of the loading and unloading racks, the push columns are aligned with the ends of the pipes, and the drilling mechanism begins to operate. The sliding cylinder drives the drilling seat to move closer to the steel pipe until the push columns on both sides extend and press against both ends of the pipe, thus positioning it. Subsequently, the drilling cylinder drives the top plate to slide downwards, and the three drilling rods on the top plate move downwards synchronously, drilling holes in the ends of the three steel pipes.

[0026] Because a pair of guide rods 14 are slidably mounted on the punch holder 8, and the tail of the guide rod is fixedly mounted on the cylinder seat 12. During the movement of the punch holder, the punch holder slides on the guide rods, and the guide rods play a stabilizing and guiding role, ensuring the accuracy of the punch holder's movement.

[0027] After drilling is completed, the sliding cylinder drives the drilling seat to reset, and the drilling cylinder drives the top plate to reset. Then, the transfer assembly operates again, moving the three drilled steel pipes forward to the unloading area to complete the unloading. Simultaneously, the three steel pipes on the placement rack are transferred back into the three grooves.

[0028] As a preferred structure, Figure 4The transfer assembly includes a lifting cylinder 15 mounted on the machine base 1. The drive shaft of the lifting cylinder is provided with a lifting plate 16. A transfer frame 17 is slidably mounted on the lifting plate. The transfer frame has a pair of front and rear limiting slots 18. The lifting plate 16 is also provided with a sliding cylinder 19. The drive shaft of the sliding cylinder is connected to the transfer frame 17.

[0029] When using the transfer assembly for loading and unloading, firstly, the sliding cylinder drives the transfer frame to move towards the placement frame, aligning the rear limit slot on the transfer frame with the three steel pipes below the placement frame. The front limit slot on the transfer frame aligns with the three steel pipes in the grooves on both sides. The lifting cylinder drives the lifting plate to rise, raising the transfer frame to a height suitable for the placement frame. The processed steel pipes in the grooves on both sides are guided into the front limit slot, and the three steel pipes on the placement frame are guided into the rear limit slot. Subsequently, the lifting plate moves up a further distance, then the sliding cylinder drives the transfer frame to reset, and the lifting cylinder drives the lifting plate to descend, causing the steel pipes on the transfer frame to fall into the grooves of the loading and unloading frame. The processed steel pipes move along the loading and unloading frame to the unloading area, thus completing the loading and unloading operation of the steel pipes.

[0030] There are three shallow grooves 22 on the left and right sides below the placement rack, which ensures that the transfer rack can transfer three steel pipes from the placement rack to the groove of the loading and unloading rack each time.

[0031] The transfer frame 17 is high in the middle and low at both ends. This structural design allows the steel pipe to slide along the transfer frame by its own weight during the transfer process, which facilitates the transfer and positioning of the steel pipe.

[0032] In addition, such as Figure 2 A baffle 20 is formed on the outer side of the placement rack 2, and a stop block 21 is formed at the front end. The baffle and the stop block work together to limit the steel pipe on the placement rack and prevent the steel pipe from slipping off the side or front end of the placement rack during placement.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
