Description

Technical Field

[0001] The utility model relates to the technical field of pipe crimping machines, in particular to a novel pipe crimping machine. Background Art

[0002] A pipe crimping machine is a device that applies a contraction force to the pipe by cooperating with a mold, thereby assembling the metal joint and the pipe. It is widely used in the pipe processing process. In actual use, the existing pipe crimping machine mainly uses an oil pump in conjunction with a single oil pipe to achieve oil delivery and oil return. In actual use, in order to avoid the pipe crimping machine from pressing the pipe too fast, the oil pipe diameter is generally small, resulting in a slow oil return rate after the pipe is pressed. To this end, in response to the above problems, a new type of pipe crimping machine is now designed to better meet actual use needs. Utility Model Content

[0003] The purpose of the present invention is to provide a new type of pipe crimping machine to solve the problems raised in the above background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a new type of pipe crimping machine, comprising a base, a main control machine and a pipe crimping machine body, wherein the main control machine is fixed to the right side of the upper end face of the base, and the pipe crimping machine body fixed to the upper end face of the base is provided on the left side of the main control machine, an oil tank is installed on the base, and the oil tank is connected to the oil delivery port through an oil pump and a conduit, and a universal valve is also installed symmetrically on the oil delivery port, and the oil delivery port is connected to the pipe crimping machine body through an oil inlet pipe, and an electromagnetic valve is installed on the oil delivery port, and the electromagnetic valve is connected to the pipe crimping machine body through an oil return pipe, and the electromagnetic valve is connected to the oil tank through the oil return pipe.

[0005] Preferably, a detachable handle is connected to the base by bolts, and the handle is symmetrically distributed about the center line of the base. The handle can be used to facilitate the transportation of the device, thereby improving the convenience of the device. The handle is a detachable structure, which facilitates the disassembly and storage of the device when in use.

[0006] Preferably, a tray is provided in the base, and the size of the tray is smaller than the size of the opening at the lower end of the base. By limiting the size of the tray, it can be ensured that the tray can be completely accommodated in the base.

[0007] Preferably, a groove is provided on the tray, and the tray is connected to the base via a telescopic slide rail. The telescopic slide rail can provide basic protection for the unfolding and storage of the tray.

[0008] Preferably, the grooves are distributed at equal intervals on the base, and the grooves are nested with the tube pressing mold. Through the nesting effect between the grooves and the tube pressing mold, multiple tube pressing molds can be stored, which facilitates the subsequent replacement of the tube pressing molds.

[0009] Preferably, the sum of the heights of the tube pressing mold and the tray is less than the height of the lower opening of the base. By limiting the sum of the heights of the tube pressing mold and the tray, the tube pressing mold is prevented from contacting the base and hindering the normal storage of the tray.

[0010] Compared with the existing technology, the beneficial effects of the present invention are: the new pipe crimping machine adopts a hand-pull mold storage mechanism, which can realize the storage function of the mold, and it is convenient to replace the mold during later use. By adding an oil return valve circuit, the hydraulic oil can be quickly returned, thereby improving work efficiency. The entire device has a high degree of integration and a small size. The detachable handle can facilitate the transportation of the device, greatly improving the convenience of using the device. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] See also Figure 1-Figure 3 The utility model provides a technical solution: a new type of pipe crimping machine, including a base 1, a main control machine 4 and a pipe crimping machine body 5. The main control machine 4 is fixed on the right side of the upper end surface of the base 1, and the pipe crimping machine body 5 fixed on the upper end surface of the base 1 is provided on the left side of the main control machine 4.

[0017] A detachable handle 101 is bolted to the base 1, and the handle 101 is symmetrically distributed about the center line of the base 1. A tray 2 is provided inside the base 1, and the size of the tray 2 is smaller than the size of the lower opening of the base 1. A groove 201 is provided on the tray 2, and the tray 2 is connected to the base 1 via a telescopic slide rail 202. The grooves 201 are evenly spaced on the base 1, and the grooves 201 are nested with the tube pressing mold 3. The sum of the heights of the tube pressing mold 3 and the tray 2 is less than the height of the lower opening of the base 1.

[0018] When using this new type of pipe pressing machine, Figure 1-Figure 3 As shown, the entire device can be carried by first holding the handle 101. After the device is placed in a suitable position, the handle 101 is disassembled to prevent the handle 101 from affecting the use of the device. During the use of the device, the nesting effect between the tube pressing mold 3 and the groove 201 can be used to store and accommodate multiple tube pressing molds 3, so that the tube pressing molds 3 can be replaced later, thereby improving the convenience of operation. The telescopic slide rail 202 can be used to expand and store the tray 2, which is convenient and simple to operate.

[0019] An oil tank 6 is mounted on the base 1 and is connected to an oil delivery port 7 via an oil pump and a conduit. A universal valve 8 is symmetrically mounted on the oil delivery port 7. The oil delivery port 7 is connected to the tube crimping machine body 5 via an oil inlet pipe 9. A solenoid valve 10 is mounted on the oil delivery port 7 and is connected to the tube crimping machine body 5 via an oil return pipe 11. The solenoid valve 10 is also connected to the oil tank 6 via the oil return pipe 11.

[0020] During use of the device, if Figure 1-Figure 3 As shown, a suitable pipe pressing mold 3 is selected according to the needs of pipe processing and installed on the pipe pressing machine body 5. During the processing, the hydraulic oil in the oil tank 6 can be transported into the pipe pressing machine body 5 through the action of the oil pump and the oil inlet pipe 9 to ensure the normal operation of the pipe pressing machine body 5. At this time, the solenoid valve 10 is in a closed state. After the pipe pressing machine body 5 completes the pipe processing, the solenoid valve 10 is opened, so that the hydraulic oil in the pipe pressing machine body 5 can quickly return through the large-sized return oil pipe 11 and return into the oil tank 6 through the conduit for next use. According to the above principle, by adding a large-diameter return oil pipe 11, the rapid return of the hydraulic oil in the pipe pressing machine body 5 can be achieved, thereby achieving rapid resetting of the pipe pressing machine body 5, and thus improving the processing efficiency. This is the working principle of the new pipe pressing machine.

[0021] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
