Description

Technical Field

[0001] The utility model relates to the technical field of nitrogen spring charging, in particular to multi-station nitrogen spring charging equipment. Background Art

[0002] Nitrogen spring is a new type of elastic component with high-pressure nitrogen as the working medium. It is small in size, large in elasticity, long in stroke, stable in operation, precise in manufacturing, long in service life, with a gentle elasticity curve, and no need for pre-tightening, etc. It can perform tasks that are difficult to accomplish with conventional elastic components such as metal springs, rubber and air cushions, simplify mold design and manufacturing, facilitate mold installation and adjustment, extend mold service life, and ensure stable product quality. It can also be designed into a nitrogen spring system and work as part of the mold. It can easily achieve constant pressure and delayed action in the system. It is a new generation of the most ideal elastic component with flexible performance.

[0003] The existing nitrogen spring charging equipment generally connects the air inlet of a single nitrogen spring with a high-pressure nitrogen cylinder by twisting the teeth to increase pressure, so as to achieve the charging of a single nitrogen spring. However, there are some problems. For example, when charging a large number of nitrogen springs, the charging method of a single twisting tooth is relatively cumbersome. Therefore, we propose a multi-station nitrogen spring charging equipment. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide a multi-station nitrogen spring inflation device, which changes the traditional inflation method of a single torque thread. The multi-station inflation device can be freely replaced between them, and the previous sealing method of torque thread pressurization is abandoned and replaced with cylinder thrust pressurization for easy disassembly, which can effectively solve the problems in the background technology.

The previous sealing method of torque tooth pressurization is abandoned and replaced by cylinder thrust pressurization for easy disassembly. The multi-station parallel connection method can ensure that the pressure of the gas spring on each station is the same, which greatly reduces the risk of pressure imbalance. The parallel connection of multiple nitrogen springs increases the charging space and can effectively avoid the phenomenon of excessive pressure increase during the charging process of a small single nitrogen spring.

The rear end surfaces of the positioning blocks are fixedly connected to the telescopic end surfaces of the cylinders adjacent to the rear side. The upper end surfaces of the sliders on the front side are installed with inflation blocks by bolts, as well as the guiding and clamping mechanisms of the inflation mechanism.

[0010] Furthermore, the inflation mechanism also includes a three-way pipe joint and a spiral pipe. The three-way pipe joint is respectively arranged on the upper end surface of each inflation block, and an inflation circuit of the spiral pipe inflation mechanism is arranged between the three-way pipe joints adjacent to each other on the left and right.

[0013] Furthermore, the reset mechanism also includes a spring, which is respectively arranged between the front end surface of the two front side supports and the rear end surface of the reset plate. The springs are fixedly sleeved on the outer side surface of the sliding column, which is the reset element of the reset mechanism.

[0014] Furthermore, it also includes a relief valve, which is arranged on the lower left side of the upper end surface of the worktable, and the upper end of the relief valve is connected in series with a pressure gauge to prevent excessive pressure during the inflation process of the nitrogen spring.

[0015] Compared with the prior art, the beneficial effects of the utility model are: the multi-station nitrogen spring charging equipment has the following advantages:

[0016] 1. The traditional inflation method of a single twisting tooth has been changed. The multi-station inflation equipment can be switched freely between 2 and 8 positions.

[0025] Inflating mechanism 5: It is evenly arranged on the front side of the upper end face of the work surface 1, and the rear end face of the inflating mechanism 5 is fixedly connected to the telescopic end face of the cylinder 8 adjacent to the rear side. The inflating mechanism 5 includes a slide rail 51, a slider 52, a positioning block 53 and an inflating block 54. The slide rail 51 is installed on the upper end face of the work surface 1 equidistantly on the left and right by bolts. Two sliders 52 are slidably connected to the outer side faces of the upper ends of each slide rail 51. The upper end faces of the sliders 52 on the rear side are installed with positioning blocks 53 by bolts. The rear end faces of the positioning blocks 53 are fixedly connected to the telescopic end faces of the cylinder 8 adjacent to the rear side. The upper end faces of the sliders 52 on the front side are installed with inflating blocks 54 by bolts. The inflating mechanism 5 also includes a three-way pipe joint 55 and a spiral pipe 56. The three-way pipe joints 55 are respectively arranged on the upper end faces of each inflating block 54, and the three-way pipe joints adjacent to the left and right are installed with the three-way pipe joints 55. A spiral pipe 56 is arranged between 55, and the inflation mechanism 5 also includes an air inlet nozzle 57, which is respectively arranged on the lower middle side of the front and rear end surfaces of the inflation block 54, and a flat seal is installed on the outer end surface of each air inlet nozzle 57. The telescopic end of the cylinder 8 extends out through the slide rail 51 and the slider 52 to drive the positioning block 53 to push the inflation block 54 forward, so that the air inlet of the nitrogen spring fits with the air inlet nozzle 57, and the nitrogen spring is supported by the V-shaped surface on the positioning plate 3 and the positioning block 53 and the air inlet nozzle 57. At the same time, the cylinder presses the air inlet of the nitrogen spring with the air inlet nozzle 57 at a constant pressure, and the sealing is achieved by the seal. Then the staff opens the control valve of the external high-pressure nitrogen bottle, and the high-pressure nitrogen enters the inflation block 54 through the external pipeline, the three-way pipe joint 55 and the spiral pipe 56, and then the nitrogen spring is inflated;

[0026] Reset mechanism 6: It is symmetrically arranged on the front side of the upper end face of the work table 1. The reset mechanism 6 includes a support 61, a sleeve 62, a slide column 63, a reset plate 64 and a second mounting bolt 65. The support 61 is symmetrically arranged on the left and right sides of the upper end face of the work table 1, respectively. A sleeve 62 is arranged between the front and rear adjacent supports 61. The middle part of the sleeve 62 is slidably connected with a slide column 63. A reset plate 64 is installed between the front end faces of the two slide columns 63 through a second mounting bolt 65. The reset mechanism 6 also includes a spring 66. The spring 66 is respectively arranged between the front end faces of the two front side supports 61 and the rear end face of the reset plate 64. The spring 66 is fixedly sleeved on the outer side face of the slide column 63. The forward movement of the inflatable block 54 drives the reset plate 64 to move forward. The forward movement of the reset plate 64 drives the slide column 63 to move forward and the spring 66 to stretch. After inflation, the staff closes the The control valve of the high-pressure nitrogen tank, and then the staff controls the retraction of the telescopic end of the cylinder 8 by controlling the external cylinder control circuit. The retraction of the telescopic end of the cylinder 8 drives the positioning block 53 to move back and reset. While the positioning block 53 moves back and resets, the reset plate 64 drives the inflation block 54 to reset through the reset of the spring 66 and the guiding effect of the sleeve 62 and the sliding column 63. The multi-station nitrogen spring inflation equipment has changed the traditional inflation method of a single twisting tooth. The multi-station inflation equipment can be freely switched between 2 and 8. The previous sealing method of twisting tooth pressurization is abandoned and replaced by cylinder thrust pressurization for easy disassembly. The multi-station parallel connection method can ensure that the pressure of the gas spring on each station is the same, which greatly reduces the risk of pressure imbalance. The parallel connection of multiple nitrogen springs increases the inflation space and can effectively avoid the phenomenon of excessive pressure increase during the inflation process of a small single nitrogen spring.

[0027] The working principle of a multi-station nitrogen spring inflation device provided by the utility model is as follows: the staff connects the external cylinder control circuit to the cylinder 8, and then connects the two end heads of the three-way pipe joints 55 on the left and right sides to the high-pressure nitrogen cylinder, and then connects the air release valve 4 in series to the inflation circuit, and then the staff places one or more groups of nitrogen springs to be inflated in pairs on the positioning plate 3 and the positioning block 53 in front and back correspondence, aligns the air inlet of each nitrogen spring with the air inlet nozzle 57, and then the staff controls the telescopic end of the cylinder 8 by controlling the external cylinder control circuit. The telescopic end of the cylinder 8 extends out, drives the positioning block 53 to push the inflation block 54 forward through the slide rail 51 and the slider 52, so that the air inlet of the nitrogen spring fits with the air inlet nozzle 57, and the nitrogen spring is supported by the V-shaped surface on the positioning plate 3 and the positioning block 53 and the air inlet nozzle 57. At the same time, the cylinder presses the air inlet of the nitrogen spring and the air inlet nozzle 57 with a constant pressure, and the sealing is achieved by the sealing member. Then the staff opens the control valve of the external high-pressure nitrogen bottle, and the high-pressure nitrogen enters the inflation block 54 through the external pipeline, the three-way pipe joint 55 and the spiral pipeline 56, and then To realize the inflation of the nitrogen spring, when the inflation block 54 moves forward, the inflation block 54 moves forward to drive the reset plate 64 to move forward, and the reset plate 64 moves forward to drive the sliding column 63 to move forward and the spring 66 to stretch. After the inflation is completed, the staff closes the control valve of the high-pressure nitrogen tank, and then the staff controls the telescopic end of the cylinder 8 to retract by controlling the external cylinder control circuit. The retraction of the telescopic end of the cylinder 8 drives the positioning block 53 to move backward and reset. When the positioning block 53 moves backward and resets, the reset plate 64 drives the inflation block 54 to reset through the reset of the spring 66 and the guiding effect of the sleeve 62 and the sliding column 63. , and then the staff can take out the inflated nitrogen spring. This multi-station nitrogen spring charging equipment has changed the traditional single-torsion tooth charging method. The multi-station charging equipment can switch freely between 2 and 8. The previous sealing method of torque pressurization is abandoned and replaced by cylinder thrust pressurization for easy disassembly. The multi-station parallel connection method can ensure that the pressure of the gas spring at each station is the same, which greatly reduces the risk of pressure imbalance. Connecting multiple nitrogen springs in parallel to increase the charging space can effectively avoid the phenomenon of excessive pressure increase during the charging process of a small single nitrogen spring.
