Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic presses, in particular to a hydraulic press for squaring steel pipes. Background Art

[0002] A hydraulic press (also known as an oil press) is a machine that uses liquid static pressure and liquid as the working medium, and is made according to Pascal's principle to transfer energy to process metal, plastic, rubber, wood, powder and other products. A hydraulic press is generally composed of three parts: the machine (host), the power system and the hydraulic control system. Hydraulic presses are classified into valve hydraulic presses, liquid hydraulic presses and engineering hydraulic presses.

[0003] When the steel pipe is squared, a hydraulic press is required to operate. However, the hydraulic press used in the existing steel pipe square production often only drives the pressing bottom plate through one hydraulic press when pushing the bottom plate to square the steel pipe. This can easily cause the pressing bottom plate to shift when in contact with the steel pipe, and the pressing bottom plate cannot be kept in a horizontal state to resist and press the steel pipe, resulting in reduced quality of the steel pipe square processing and inconvenience for users. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a hydraulic press for squaring steel pipes, which solves the problem that when the hydraulic press used in the existing steel pipe squaring production pushes the bottom plate to square the steel pipe, the pressing bottom plate is often driven by only one hydraulic press, which can easily cause the pressing bottom plate to shift when in contact with the steel pipe, and the pressing bottom plate cannot be kept in a horizontal state to resist and press the steel pipe, resulting in reduced quality of steel pipe squaring and inconvenience for users.

[0005] The utility model provides the following technical solution: a hydraulic press for squaring steel pipes, comprising a processing base, two start buttons are symmetrically arranged at the top of the side of the processing base, side support columns are arranged around the processing base, the bottom ends of the side support columns are arranged with base connecting plates, and a steel pipe square processing bin is arranged on the top of the processing base;

[0024] See also Figure 1-4

[0025] Embodiment 1: A hydraulic press for squaring steel pipes comprises a processing base 1, two start buttons 2 are symmetrically arranged at the top of the side of the processing base 1, side support columns 3 are arranged around the processing base 1, base connecting plates 4 are arranged at the bottom ends of the side support columns 3, and a steel pipe square processing bin 5 is arranged on the top of the processing base 1.

[0026] Two safety gratings 6 are symmetrically and slidingly arranged on both sides of the steel pipe square processing warehouse 5, a steel pipe support plate 7 is arranged at the bottom of the steel pipe square processing warehouse 5, two movable slide grooves 8 are symmetrically opened at the top of the steel pipe support plate 7, a limiting block 9 is arranged at the top of the steel pipe support plate 7, a processing resistance plate 10 is arranged above the steel pipe support plate 7, and limiting connecting columns 11 are inserted through the four sides of the steel pipe support plate 7.

[0027] The top of the limiting connecting column 11 passes through the four sides of the processing resistance plate 10, and both ends of the limiting connecting column 11 are connected to the inner wall of the steel pipe square processing warehouse 5. A main hydraulic cylinder 12 is installed in the middle of the top of the steel pipe square processing warehouse 5, and the driving end at the bottom of the main hydraulic cylinder 12 passes through the top of the steel pipe square processing warehouse 5 and is connected to the top surface of the processing resistance plate 10.

[0028] Two auxiliary hydraulic cylinders 13 are symmetrically arranged on both sides of the main hydraulic cylinder 12. The driving shaft at the bottom end of the auxiliary hydraulic cylinder 13 passes through the top of the steel pipe square processing warehouse 5 and is connected to both sides of the top of the processing contact plate 10. An auxiliary oil tank 14 is arranged on the side of the main hydraulic cylinder 12. An electric control box 15 is installed on the top of the steel pipe square processing warehouse 5. A three-color light 16 is arranged on the side of the electric control box 15. Two closed switch doors 17 are symmetrically rotated on the rear side of the steel pipe square processing warehouse 5.

[0029] Embodiment 2: The difference between this embodiment and embodiment 1 is that the bottom end of the safety grating 6 is slidably inserted into a slide rail arranged outside the steel pipe square processing bin 5 through an arranged slider.

[0030] This allows the user to pull the safety gratings 6 arranged on both sides of the steel pipe square processing bin 5 more smoothly.

[0031] Embodiment 3: The difference between this embodiment and embodiment 1 is that, the driving end at the bottom of the main hydraulic cylinder 12 is connected to the middle part of the top end of the processing resistance plate 10 through a provided connecting block.

[0032] This makes the machining resistance plate 10 driven by the main hydraulic cylinder 12 more stable.

[0033] Embodiment 4: The difference between this embodiment and embodiment 1 is that a latch for closing is provided on the closing switch door 17 .

[0034] The rear side of the steel pipe square processing chamber 5 can be opened, so that a relatively long steel pipe can be conveniently inserted into the steel pipe square processing chamber 5 for square processing.

[0035] In this embodiment, due to the hydraulic press used in the existing steel pipe squaring production, when pushing the base plate to square the steel pipe, the pressing base plate is often driven by only one hydraulic press, which can easily cause the pressing base plate to shift when contacting the steel pipe, and the pressing base plate cannot be kept in a horizontal state to resist and press the steel pipe, resulting in a reduction in the quality of the steel pipe squaring processing and inconvenience for users.

[0036] In summary, in specific operations, when the user needs to square the steel pipe into a square steel pipe, the user first needs to open the closed switch door 17 on the rear side of the steel pipe square processing bin 5, so that the steel pipe to be processed can pass through the steel pipe square processing bin 5, or when the processed steel pipe is small in volume, it can also be directly placed in the steel pipe square processing bin 5 for processing, and the steel pipe is placed on the top of the steel pipe support plate 7, and the limit block 9 set on the steel pipe support plate 7 can play a certain role in limiting the side of the steel pipe.

[0037] Next, the user activates the start button 2 and the electric control box 15 with both hands, and the main hydraulic cylinder 12 and the auxiliary hydraulic cylinder 13 are activated, so that the driving ends of the main hydraulic cylinder 12 and the auxiliary hydraulic cylinder 13 push downward the processing resistance plate 10 arranged above the steel pipe support plate 7, and because the middle part of the processing resistance plate 10 is pushed by the main hydraulic cylinder 12, the two sides of the top of the processing resistance plate 10 are pushed by the auxiliary hydraulic cylinder 13.

[0038] At the same time, the four sides of the processing resistance plate 10 are also penetrated and limited by the limiting connecting columns 11, so that after being limited in multiple directions, the processing resistance plate 10 can only move in the up and down directions, and the bottom end surface of the processing resistance plate 10 is always kept in a horizontal state during the movement, so that the steel pipe to be processed placed on the steel pipe support plate 7 can be pressed and resisted more accurately.

[0039] The steel pipe can be processed into a square shape to meet the processing requirements of the user. There will be no tilting or deviation problem when the resistance plate 10 presses the steel pipe. Each time the steel pipe is pressed, it is in a horizontal state, so that a higher quality square steel pipe can be processed, which is convenient for users.
