Description

Technical Field

[0001] The utility model relates to the technical field of pipe punching devices, in particular to a precision punching machine for aluminum alloy pipes from inside to outside. Background Art

[0002] Radiator is a general term for a series of devices used to conduct and release heat. Commonly used radiators are terminal devices for home heating. The heat sources are generally urban centralized heating, community self-built boiler rooms, household wall-mounted boilers, etc. The heat is dissipated through heat conduction, radiation, and convection to increase the temperature of the room. The heating radiators currently sold on the market are basically divided into aluminum tube and aluminum fin convection radiators, steel radiators, aluminum radiators, stainless steel radiators, aluminum-aluminum composite radiators, etc. The pipes in the radiator need to be punched to connect adjacent heat dissipation modules.

[0003] The punching tool commonly used in the punching mechanism of the pipe punching device is generally provided with a vertical through hole in the center of the tool. When using this punching tool to punch the pipe, the waste chips generated during the pipe punching can easily enter the tool through the through hole, move with the punching tool, and adhere to the surface of the punching tool, affecting the punching quality. Moreover, after long-term use, these waste chips will accumulate in the through hole and are difficult to clean, affecting the normal use of the punching tool.

[0004] The prior art discloses a patent with publication number CN205588402U. This solution includes a punching tool and a tool fixing chuck. The punching tool is fixedly mounted on the tool fixing chuck. The punching tool has a vertical through-hole extending vertically in the center. The punching tool is characterized by also including a chip removal mechanism. The chip removal mechanism includes a waste chip ejection needle. The lower portion of the waste chip ejection needle extends from top to bottom into the through-hole and can move up and down within the through-hole. The waste chip ejection needle is provided with an ejection mechanism for driving the waste chip ejection needle to move up and down. The ejection mechanism is provided above the punching tool. In the initial state, the bottom end surface of the waste chip ejection needle is located above the bottom end surface of the punching tool. The advantage is that the chip removal mechanism is provided on the punching mechanism. The chip removal mechanism includes a waste chip ejection needle extending into the through-hole. The ejection mechanism drives the waste chip ejection needle to move up and down within the through-hole of the punching tool, thereby promptly and effectively disposing of waste chips that enter the punching tool. The structure is simple and the operation is convenient.

[0005] As the existing devices are used, the shortcomings of this technology are gradually exposed, mainly in the following aspects:

[0006] First, the existing punching devices punch from the outside to the inside during use, which causes the pipe to be easily deformed during the punching process, affecting the punching quality.

It is convenient and fast, and the moving distance of the feed table can be controlled by the screw to punch holes of different spacings. After the position is in place, the stamping upper support seat and the stamping upper support seat are used to press and position the pipe, and the upper clamping seat and the lower clamping seat release the clamping of the pipe and reset under the action of the feed table to prepare for feeding the next punching position.

A stamping guide hole 15 is opened on the lower surface of the support mold tube 17, and the stamping head 12 is constrained in the stamping guide hole 15 along the vertical sliding.

[0032] The areas on both sides of the stamping lower support seat 2 on the support platform 1 are respectively provided with clamping and feeding components, and the two clamping and feeding components are synchronously slidably arranged in the horizontal direction.

[0033] A blanking channel 16 that is aligned with the punching guide hole 15 is provided on the punching lower support seat 2 .

[0034] A T-shaped chute 14 is provided on the driving inclined surface 11 , and a slider 13 matching the chute 14 is fixedly connected to the upper end of the punch head 12 .

[0035] The lower surface of the punch head 12 is provided with an upward concave punching surface.

[0036] The clamping and feeding assembly includes a lower clamping seat 4 and an upper clamping seat 5 located at the upper and lower sides of the pipe 18, and the upper clamping seat 5 is arranged to rise and fall in the vertical direction.

[0037] A feed table is provided on the support platform 1 for horizontal sliding. The lower clamping seat 4 is fixed to the upper surface of the feed table. Each corresponding upper clamping seat 5 of the feed table is fixed with a side frame 6. The upper end of the side frame 6 is vertically fixed with a clamping cylinder 7. The upper clamping seat 5 is fixed to the telescopic end of the clamping cylinder 7.

[0038] Two guide rails 22 are fixedly connected in parallel on the support platform 1 , and a guide seat 23 matching the guide rails 22 is fixedly connected to the lower surface of the feed table.

[0039] A screw 24 is provided on the support platform 1 for horizontal rotation, and the screw 24 is threadedly connected to one of the guide seats 23 .

[0040] End seats supporting the lead screw 24 are fixedly connected in parallel on the support platform 1 , and a driving machine 25 for driving the lead screw 24 to rotate is fixedly connected to one of the end seats.

[0041] A side plate 20 is vertically fixed to the support platform 1, one end of the support mold tube 17 is fixed to the side plate 20, and a drive rod 19 is provided in the support mold tube 17 for horizontal reciprocating sliding.
