Description

Technical Field

[0001] The utility model relates to the technical field of cold drawing machines, in particular to a hydraulic cold drawing machine for special-shaped steel pipes. Background Art

[0002] Special-shaped steel pipes, also known as special-shaped pipes, refer to steel pipes with irregular cross-sectional shapes or special cross-sectional shapes. They not only have good mechanical properties, but also can meet specific use environments and functional requirements. They are widely used in construction, machinery, automobiles and other fields. When processing special-shaped steel pipes, hydraulic cold drawing machines are required. The hydraulic cold drawing machine can be used to adjust the structure and performance of special-shaped steel pipes through cold drawing.

[0003] A Chinese patent discloses a hydraulic cold drawing machine for special-shaped steel pipes (authorization announcement number CN220970396U). This patented technology drives the threaded rod to rotate by controlling the driving motor, and drives the sliding blocks on both sides of the threaded rod to move inward through the rotation of the threaded rod. At the same time, the cleaning motors on both sides are turned on, and the cleaning motors drive the turntable to rotate. The water in the water tank is pumped out through the water pipe by turning on the water pump, and the water is sprayed toward the steel pipe through the flushing head at the end of the serpentine pipe for cleaning. At the same time, the rotation of the turntable drives the cleaning brush inside to brush the surface of the steel pipe, thereby removing the mud and dirt on the surface of the steel pipe, thereby preventing it from following the steel pipe into the mold and affecting the mold.

[0004] However, most existing cold drawing methods for special-shaped steel pipes involve pulling the special-shaped steel pipe, which results in poor positioning during cold drawing and affects the cold drawing process. For example, the aforementioned reference document employs a method of pulling the special-shaped steel pipe. However, in actual use, if the special-shaped steel pipe is not firmly fixed during cold drawing, it is prone to falling off, affecting the cold drawing process. Therefore, those skilled in the art have provided a hydraulic cold drawing machine for special-shaped steel pipes to address the problems raised in the above-mentioned background art. Utility Model Content

[0005] The purpose of the utility model is to provide a hydraulic cold drawing machine for special-shaped steel pipes to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A hydraulic cold drawing machine for special-shaped steel pipes includes a base plate, a fixed plate is provided at the end surface of the upper surface of the base plate, and a cold drawing plate is also slidably installed on the upper surface of the base plate, one side of the cold drawing plate and the fixed plate are provided with an installation groove, a positioning frame is embedded and installed inside the installation groove, a telescopic cylinder is symmetrically provided on the upper surface of the positioning frame, a positioning groove is provided on one side of the positioning frame, and a clamping plate is provided inside the positioning groove inside the positioning frame, the front and rear surfaces of the cold drawing plate and the fixed plate are provided with fixing rods, and a limiting rod is provided through one end of the fixing rod.

[0010] As a further solution of the present invention: two groups of moving blocks are provided on the lower surface of the cold-drawn plate, and the moving blocks are arranged in a "T" shape.

[0011] As a further solution of the present invention: a connecting sleeve is symmetrically provided on the upper surface of the pressing plate, the telescopic end of the telescopic cylinder is embedded in the connecting sleeve and connected by screws, and an anti-slip layer is provided on the lower surface of the pressing plate.

[0012] As a further solution of the present invention: the front surface and the rear surface of the positioning frame are both provided with limiting holes, and one end of the limiting rod is embedded in the limiting hole.

[0013] As a further solution of the present invention: an electric telescopic rod is provided inside the fixed rod, and the telescopic end of the electric telescopic rod is connected to one end of the limiting rod.

[0014] Compared with the prior art, the beneficial effects of the present invention are:
