Description

Technical Field

[0001] The present invention relates to the technical field of copper tube forming, and specifically relates to a copper tube red punching and hot forging forming die. Background Art

[0002] Forging can be divided into cold forging and hot forging according to the temperature of the blank during processing. Cold forging is generally processed at room temperature, and hot forging is processed at a temperature higher than the recrystallization temperature of the blank metal. Sometimes, forging carried out while the blank is in a heated state but the temperature does not exceed the recrystallization temperature is called warm forging. However, this division is not completely unified in production.

[0003] In order to reduce safety hazards in the factory area and improve the production efficiency of copper tubes, a manipulator is added to the hot forging equipment of copper tubes to complete the handling of the heated copper tubes. The manipulator transports the copper tubes one by one into the die. Although this method is orderly, there is still a large room for improvement in production efficiency. Summary of the Invention

[0004] The present invention aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] For this reason, the technical solution adopted by the present invention is as follows:

The feeding module includes two discharging pipes arranged on the top of the turntable, two spring steels installed inside the discharging pipes, a connecting frame connected between the two discharging pipes, a guiding plate installed outside the discharging pipes, a plate body slidably sleeved outside the guiding plate, a second motor installed outside the discharging pipes, a threaded rod connected to the output shaft of the second motor, a first cylinder embedded in the top of the plate body, an L-shaped pressing rod connected to the movable end of the first cylinder, and a plug plate slidably penetrating through the discharging pipe and connected to the plate body. A round opening is formed on the plug plate, and an opening suitable for the lifting of the L-shaped pressing rod is formed on the discharging pipe. The threaded rod horizontally threadedly penetrates the plate body. The forming module includes an L-shaped support plate installed on the top of the workbench, a second cylinder penetrating through the L-shaped support plate, a pushing and pulling plate connected to the movable end of the second cylinder, a U-shaped push rod connected to the pushing and pulling plate, a cross plate connected to the U-shaped push rod, and a plurality of hydraulic cylinders connected to the cross plate. The plurality of hydraulic cylinders are connected in series. The discharging module includes a plurality of arc-shaped openings formed at the bottom of the workbench and a roller conveyor sleeved on the bottom of the workbench.

[0007] By adopting the above technical solution, the external PLC starts two second motors simultaneously, and then the second motors make the plate body translate along the guide plate through the threaded rods. The L-shaped pressing rod and the inserting plate follow the translation. Since the length of the inserting plate is greater than that of the L-shaped pressing rod, the round opening is first connected to the inside of the discharge pipe, and then the copper tube drops downward and is limited by the clamping channel. After that, the L-shaped pressing rod enters the inside of the discharge pipe, and then the first cylinder and the third cylinder are started. With their cooperation, the L-shaped pressing rod presses the copper tube out of the discharge pipe. Then two copper tubes are inserted into the molds. Then the first motor is started, and the turntable makes multiple molds change positions. Then in the same way, copper tubes are inserted into the other two molds, realizing efficient feeding and providing conditions for efficient production.

[0008] In a preferred example of the present invention, it can be further configured that: a clamping channel is formed between two spring steels, and the clamping channel is located at the bottom of the L-shaped pressing rod.

[0009] In a preferred example of the present invention, it can be further configured that: the second motor is located between the L-shaped pressing rod and the inserting plate, the inserting plate is located at the top of the second motor, and the inner end of the inserting plate is set to be a sharp angle.

[0010] In a preferred example of the present invention, it can be further configured that: the push-pull plate and the U-shaped push-pull rod are both made of alloy materials, and the bottom of the push-pull plate fits against the top of the L-shaped support plate.

[0011] In a preferred example of the present invention, it can be further configured that: a plurality of arc-shaped openings are respectively located at the bottoms of a plurality of molds, and the plurality of arc-shaped openings are arranged at equal intervals and in a circular pattern.

[0012] In a preferred example of the present invention, it can be further configured that: a plurality of ball seats are installed inside the workbench, the plurality of ball seats are arranged at equal intervals and in a circular pattern, and the ball seats and the arc-shaped openings are arranged in a staggered manner.

[0013] In a preferred example of the present invention, it can be further configured that: a stability enhancing component is provided at the bottom of the guide plate, and the stability enhancing component includes an L-shaped plate installed on one side of the guide plate and a third cylinder connected between the L-shaped pressing rod and the L-shaped plate, and the third cylinder is connected in series with the first cylinder.

[0014] In a preferred example of the present invention, it can be further configured that: the first motor, the second motor, the second cylinder, the hydraulic cylinder, the roller conveyor and the third cylinder are all electrically connected to an external PLC.

[0015] By adopting the above technical solution, the beneficial effects achieved by the present invention are:

[0016] 1. In the present invention, an external PLC starts two second motors simultaneously. Then, the second motors drive a threaded rod to make a plate body translate along a guide plate. The L-shaped pressure rod and the insertion plate follow the translation. Since the length of the insertion plate is greater than that of the L-shaped pressure rod, the round opening first communicates with the inside of the discharge pipe. Then, the copper tubes fall downward and are limited by the clamping channels. After that, the L-shaped pressure rod enters the inside of the discharge pipe. Then, the first cylinder and the third cylinder are started. Under their cooperation, the L-shaped pressure rod presses the copper tubes out of the discharge pipe. Then, two copper tubes are inserted into the molds. Then, the first motor is started, and the turntable makes multiple molds change positions. Then, in the same way, copper tubes are inserted into the other two molds, achieving efficient feeding and providing conditions for efficient production.

[0017] 2. In the present invention, the second cylinder is started. The second cylinder makes a cross plate hang above the turntable through a push-pull plate and a U-shaped push-pull rod. Then, multiple hydraulic cylinders are started. The hydraulic cylinders press the copper tubes out of the molds. Each mold is equipped with a hydraulic cylinder, and multiple hydraulic cylinders can be started simultaneously, effectively improving the forming efficiency of the copper tubes.

[0018] 3. In the present invention, after the copper tubes are formed, they fall from the arc-shaped opening. Then, a roller conveyor uniformly conveys these formed copper tubes, improving the comfort of use. Description of the Drawings

The feeding module 100 includes a workbench 110, a first motor 120 embedded inside the workbench 110, a turntable 130 connected to the output shaft of the first motor 120, and a plurality of molds 140 connected to the top of the turntable 130. The turntable 130 is movably embedded on the top of the workbench 110

[0039] The feeding module 200 includes two discharging pipes 210 arranged on the top of the turntable 130, two spring steels 220 installed inside the discharging pipes 210, a connecting frame 230 connected between the two discharging pipes 210, a guiding plate 240 installed outside the discharging pipes 210, a plate body 250 slidably sleeved outside the guiding plate 240, a second motor 260 installed outside the discharging pipes 210, a threaded rod 270 connected to the output shaft of the second motor 260, a first cylinder 280 embedded in the top of the plate body 250, an L-shaped pressing rod 290 connected to the movable end of the first cylinder 280, and an inserting plate 291 slidably penetrating through the discharging pipe 210 and connected to the plate body 250.

The ball seats 500 are provided to support the turntable 130 and also provide smoothness for the rotation of the turntable 130. Embodiment

[0048] Combined with Figure 1 、 2 、3、5 and Figure 9 As shown, in the above embodiment, a stability-enhancing component 600 is provided at the bottom of the guide plate 240. The stability-enhancing component 600 includes an L-shaped plate 610 installed on one side of the guide plate 240 and a third cylinder 620 connected between the L-shaped pressure bar 290 and the L-shaped plate 610. The third cylinder 620 is connected in series with the first cylinder 280. The stability-enhancing component 600 is provided to ensure that the L-shaped pressure bar 290 can press the copper tubes on the clamping channel out of the discharge pipe 210.

[0049] Working principle and usage process of the present invention: In the initial state, the heated copper tubes are neatly arranged in both discharge pipes 210. Then, the movable end of the second cylinder 280 is in a contracted state, and the cross plate 350 indirectly connected to the second cylinder 280 leaves the top of the turntable 130. Then, when the device is put into actual use, an external PLC simultaneously starts two second motors 260. Then, the second motors 260 drive the plate body 250 to translate along the guide plate 240 through the threaded rods 270. Then, the plate body 250 drives the L-shaped pressing rod 290 and the insertion plate 291 to translate. Since the length of the insertion plate 291 is greater than that of the L-shaped pressing rod 290, the round through hole on the insertion plate 291 is the first to communicate with the inner diameter of the discharge pipe 210. Then, the copper tubes in the discharge pipe 210 fall downward, and the copper tubes are limited by the clamping channel. After that, the L-shaped pressing rod 290 enters the interior of the discharge pipe 210. At this time, the insertion plate 291 has closed the discharge pipe 210 above it. Then, the external PLC simultaneously starts the first cylinder 280 and the third cylinder 620. Under their cooperation, the L-shaped pressing rod 290 presses the copper tubes out of the discharge pipe 210. When two copper tubes are inserted into the mold 140, the first motor 120 is started. The first motor 120 drives the turntable 130 to replace the positions of multiple molds 140. Then, in the same way, the other two molds 140 are inserted with copper tubes for efficient feeding and efficient production. Then, the second cylinder 320 is started. The second cylinder 320 makes the cross plate 350 hang above the turntable 130 through the push-pull plate 330 and the U-shaped push-pull rod 340. Then, multiple hydraulic cylinders 360 are started. The hydraulic cylinders 360 press the copper tubes out of the mold 140. Then, the copper tubes are formed and then fall from the arc-shaped opening 410. Then, the roller conveyor 420 uniformly conveys these formed copper tubes to improve the usage comfort.

[0050] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
