Description

Technical Field

[0001] The present application relates to the technical field of pipe processing, and in particular to a hydraulic automatic pipe shrinking machine. Background Art

[0002] During the processing of pipe fittings, it is often necessary to connect them to each other. The hydraulic automatic pipe shrinking machine is mainly used to shrink or expand the pipe fittings, so that pipe fittings with the same diameter can be connected to each other after shrinking.

[0003] The existing hydraulic automatic tube shrinking machine includes a chuck mechanism for clamping tube fittings, a tube shrinking mechanism for shrinking the tube fittings, and a driving mechanism for driving the tube shrinking mechanism close to the chuck mechanism. Generally, two tube shrinking grinding heads are provided on the tube shrinking mechanism to shrink the tube fittings in stages to reduce the possibility of damage to the tube fittings. Before shrinking the tube, the tube fitting is first fixed on the chuck mechanism, one end of the tube fitting extends out of the chuck mechanism, and then lubricating oil is applied to the side wall of the tube fitting, and then the tube shrinking mechanism is driven close to the tube fitting to shrink the tube fitting.

[0004] Regarding the above-mentioned related technologies, when applying lubricating oil to the pipe fittings, the operator is required to hold a brush to apply oil to the end of the pipe fitting, which is not only labor-intensive, but also when the tube shrinking mold is close to the chuck, it may be added to the operator, posing a safety hazard. Utility Model Content

[0005] In order to improve the oiling efficiency of pipe fittings and reduce potential safety hazards, the present application provides a hydraulic automatic pipe shrinking machine.

The oil collecting mechanism comprises an oil collecting frame for collecting excess lubricating oil. The oil collecting frame is arranged between the chuck mechanism and the tube shrinking mechanism and is located below the end of the tube fitting.

[0008] By adopting the above technical solution, the oil spray head sprays oil on the side wall of the pipe fitting, and the belt body is manually oiled, which can improve the oiling efficiency and reduce safety hazards; at the same time, the excess lubricating oil during spraying is collected by the oil collecting frame, which can reduce the possibility of lubricating oil contaminating the machine.

[0009] Optionally, two oil spray heads are provided, and the two oil spray heads are respectively located on the upper and lower sides of the pipe fitting, and the automatic tube shrinking machine also includes a clamping mechanism for clamping the oil spray heads.

[0012] By adopting the above technical solution, the fuel injection head can be fixed, and by adjusting the positioning rod up and down, the fuel injection head can be adjusted up and down, that is, the distance between the fuel injection head and the pipe can be adjusted to improve the fuel injection effect.

[0013] Optionally, a guide groove for the positioning rod to pass through is formed on the support rod, the guide groove extends along a vertical direction, and both of the positioning rods pass through the guide groove.

[0014] By adopting the above technical solution, the guide groove can guide the sliding direction of the positioning rod, thereby limiting the movement of the positioning rod in the horizontal direction.

[0016] By adopting the above technical solution, rotating the bidirectional screw can drive the two positioning rods on the bidirectional screw to move closer to or away from each other at the same time, that is, it can drive the two oil injection heads on the positioning rod to move closer to or away from the pipe fitting at the same time.

[0017] Optionally, the driving member further includes a handle rotatably disposed on the support rod, and the bidirectional screw rod extends upward to be connected to the handle.

[0018] By adopting the above technical solution, the bidirectional screw can be rotated by rotating the handle.

[0019] Optionally, the positioning member includes two hoops arranged on the positioning rod, and fixing bolts and positioning nuts passing through the hoops, and positioning holes for the positioning bolts to pass through are formed at one end of the two hoops away from the positioning rod.

[0020] By adopting the above technical solution, the fuel injection head is first passed through the clamp, and then the positioning bolt is passed through the positioning hole, and is locked by the positioning nut, so that the two clamps can be driven to press against the fuel injection head, thereby fixing the fuel injection head.

[0021] Optionally, the oil collecting mechanism further comprises a filter plate arranged on the oil collecting frame, and the oil collecting frame is provided with a slot for clamping the filter plate.

[0022] By adopting the above technical solution, larger impurities that may exist in the used lubricating oil can be filtered, so that the lubricating oil collected in the oil collecting frame is relatively clean and convenient for reuse.

[0023] Optionally, the oil collecting mechanism further includes an adsorption filter layer disposed on the oil collecting frame.

[0024] By adopting the above technical solution, the adsorption filter layer can filter smaller impurities that may exist in the lubricating oil, thereby improving the filtering effect.

[0025] In summary, the present application includes at least one of the following beneficial effects:

[0026] 1. Spraying lubricating oil on the side wall of the pipe fittings through two oil spray heads can lubricate the pipe fittings conveniently and quickly. Compared with manual oiling, it is more efficient and can reduce safety hazards;

[0027] 2. The oil collecting frame can reduce the possibility of lubricating oil falling on the machine. At the same time, the collected lubricating oil can be filtered through the filter plate and the adsorption filter tank to facilitate the recycling of the lubricating oil.

[0035] Reference Figure 1 and Figure 2 In the present embodiment, the oiling mechanism 4 includes an oil spray head 41 capable of spraying lubricating oil, an oil tank 43 for storing lubricating oil, and a pump body 42 connected between the oil spray head 41 and the oil tank 43. The oil tank 43, the pump body 42 and the oil spray head 41 are connected by a hose. There is no restriction on the pump body 42 as long as the lubricating oil can be sprayed from the oil spray head 41 at a certain pressure. The oil spray head 41 is preferably an atomizing nozzle, so that the lubricating oil sprayed onto the side wall of the pipe 101 is more uniform and the spray coverage is wider.

[0036] Reference Figure 1 and Figure 2 In the present embodiment, two oil spray heads 41 are provided and are respectively located at the upper and lower sides of the end of the pipe fitting 101, thereby improving the effect of spraying lubricating oil on the surface of the pipe fitting 101. When the tube shrinking grinding head on the tube shrinking mechanism 3 is close to the chuck mechanism 2, the end of the pipe fitting 101 is inserted into the tube shrinking grinding head. At this time, the oil spray head 41 will not interfere with the tube shrinking grinding head.

A guide groove 611 for the positioning rod 62 to pass through is opened on the support rod 61, and the guide groove 611 penetrates the two side walls of the support rod 61 and extends along the vertical direction. The two positioning rods 62 are both passed through the guide groove 611, thereby being restricted from moving and rotating in the horizontal direction; the driving member 63 includes a bidirectional screw 631 and a handle 632 rotatably arranged on the support rod 61, the upper and lower ends of the bidirectional screw 631 are inserted into the upper and lower side walls of the guide groove 611 and are rotatably connected to the support rod 61 through bearings and the like, and the upper end of the bidirectional screw 631 extends upward and is rotatably connected to the handle 632.

[0040] In other embodiments, a motor may be provided on the support rod 61, and the output end of the motor is connected to the end of the bidirectional screw 631, so that the handle 632 can be replaced to drive the motor to rotate, thereby sliding the positioning rod 62 up and down.
