Description

Technical Field

[0001] The present application relates to the technical field of steel pipe processing, and specifically discloses a steel pipe blanking device. Background Art

[0002] In the production and processing of steel pipes as well as the recycling of steel pipes, steel pipe cutting is one of the essential processes. For example, steel pipes are prone to rust after being placed for a long time. In order to ensure the normal use of steel pipes, the surface of the steel pipes needs to be derusted and cleaned in time to facilitate subsequent processing.

[0003] At present, the grinding of steel pipes is mostly done by grinding machines. During grinding, the staff needs to place the steel pipe in the grinder. When one steel pipe is finished, the next steel pipe is taken out and put into the grinder to continue. Rust removal of steel pipes is generally done in multiple batches. The number of steel pipes in each batch is hundreds or even thousands. The staff has to carry the steel pipes to the grinder non-stop. The staff carries a large number of steel pipes every day, which is labor-intensive and easy to cause lumbar muscle strain. It is difficult to grasp the feeding interval of the steel pipes when feeding the steel pipes manually, and it is impossible to achieve intermittent and uniform feeding of the steel pipes. It is very inconvenient to use and is not conducive to automated production.

[0004] In view of this, the utility model provides a steel pipe feeding device to solve the above problems. Utility Model Content

[0005] The utility model aims to solve the problem that the traditional steel pipe rust removal requires the staff to put the steel pipe into the grinder, which is not convenient for automated production.

[0006] In order to achieve the above-mentioned purpose, the basic scheme of the utility model provides a steel pipe feeding device, comprising:

[0007] The storage bin is used to place steel pipes that need to be processed in batches. The bottom of the storage bin is provided with a discharge hopper that matches the diameter of the steel pipe;

[0008] An intermittent material discharge assembly comprises a sliding frame slidably connected to the discharge hopper, a first connecting rod and a second connecting rod respectively arranged on both sides of the sliding frame in an upper and lower staggered manner, the first connecting rod is provided with a plurality of top columns which can be extended into the discharge hopper, and the second connecting rod is provided with a plurality of bottom columns which can be extended into the discharge hopper;

[0009] The power member drives the sliding frame to slide back and forth.

[0010] The principles and effects of this basic solution are:

[0011] Compared with the prior art, the utility model drives the sliding frame to slide back and forth through a power part, so that the first connecting rod and the second connecting rod slide back and forth along the discharge hopper, so that the steel pipe in the storage bin falls from above the top column to between the top column and the bottom column, and then falls to below the bottom column, so that the steel pipe can be intermittently discharged in a stable cycle, solving the problem that traditional steel pipe rust removal requires workers to put the steel pipe into a grinder, which is not convenient for automated production.

[0012] Furthermore, the output end of the power member is connected to a fan gear, and the sliding frame is symmetrically provided with racks symmetrically located on both sides of the fan gear. The power member drives the fan gear to rotate, and the fan gear is engaged with the racks on both sides, thereby driving the sliding frame to slide back and forth. The structure is compact as a whole, and the control process of driving the sliding frame to slide is more convenient and quick.

[0013] Furthermore, the sliding frames are two and symmetrically arranged at both ends of the discharge hopper, and the first connecting rod and the second connecting rod are respectively arranged between the two sliding frames. The two sliding frames are symmetrically arranged, which can improve the stability of the first connecting rod and the second connecting rod structure and prevent the first connecting rod and the second connecting rod from being offset during operation.

[0014] Furthermore, the sliding frame includes sliding rods for mounting the racks and connecting rods for connecting the ends of the two sliding rods, and the side walls of the discharge hopper are symmetrically provided with limit rails for accommodating the sliding rods to slide. The arrangement of the sliding rods and the connecting rods not only improves the structural strength of the sliding frame as a whole, but also makes the sliding frame as a whole more compact, avoiding positional displacement of the sliding frame during use, and the limit rails play a role of limiting and guiding in this process, while also ensuring stable meshing between the rack and the fan gear.

[0015] Furthermore, the vertical height difference between the first connecting rod and the second connecting rod is adapted to the diameter of the steel pipe, so that only one steel pipe can be accommodated between the top column and the bottom column, preventing multiple steel pipes from falling from the discharge hopper at the same time, thereby improving the stability of material discharge.

[0016] Furthermore, the bottom of the discharge bin is provided with an inclined surface to facilitate the steel pipes to slide into the discharge hopper. The inclined surface prevents the steel pipes from accumulating in the corners of the discharge bin and affecting the normal loading process.

[0017] Furthermore, the sliding frame is hinged with an adjustment shaft on one side away from the first connecting rod, and a push rod is provided on the adjustment shaft, which can pass through the inclined surface and extend into the discharge bin. The adjustment shaft and the push rod are arranged so that when the sliding frame moves, the push rod reciprocates to push the steel pipe in the discharge hopper, preventing the steel pipes from being squeezed against each other and unable to fall into the discharge hopper, thereby further improving the stability of the steel pipe feeding process.
