Description

Technical Field

[0001] This utility model relates to the technical field of hardware processing, specifically to a punching device for hardware pipe fittings. Background Technology

[0002] Hardware: Traditional hardware products, also known as "small hardware." It refers to the five metals—gold, silver, copper, iron, and tin—that, through artificial processing, can be made into works of art such as knives and swords, or metal components. In modern society, hardware is much broader, including hardware tools, hardware parts, daily-use hardware, building hardware, and security products. Small hardware products are mostly not final consumer goods. Hardware is usually initially processed into sheet or cylindrical shapes, so it needs to be cut.

[0003] The existing punching and cutting equipment for metal pipe fittings has the following problem when used:

[0004] When performing punching operations at different positions, it is necessary to loosen the clamped and positioned pipe fittings and then adjust the clamping position of the pipe fittings to ensure that their punching position is consistent with the punching mechanism. The punching mechanism itself cannot be adjusted independently, which greatly affects the convenience of punching operations for hardware pipe fittings and reduces processing efficiency. Secondly, during the punching process of pipe fittings, the existing positioning and clamping mechanism is prone to displacement and shaking due to the punching force on the pipe fittings, and its clamping stability and support need to be improved.

[0005] Therefore, this utility model proposes a punching device for metal pipe fittings. Utility Model Content

[0014] Furthermore, the limiting seat is arranged in a stepped shape, with an opening in its vertical section. The top of the opening is rectangular and the bottom is circular. The mounting cavity is located on the surface of the horizontal section of the limiting seat.

[0015] Furthermore, the toothed roller, drive shaft, and drive mechanism are adjusted to be horizontally aligned, with the drive shaft and drive mechanism both located within the limit seat.

[0016] Furthermore, the protective layer, guide ring frame, and limiting ring frame are stacked from the inside out at the opening positions on the vertical section surface of the limiting seat.

[0017] Furthermore, the protective layer, guide ring frame, and limit ring frame are all open, with a rectangular vertical opening at the top and a circular opening at the bottom, and the protective layer is set as a damping pad layer.

[0018] Furthermore, the outer surface of the limiting ring frame is provided with a toothed rack corresponding to the adjusting toothed roller, and the limiting ring frame and the guide ring frame are movably connected by an arc-shaped track.

Each set includes a guide rail fixedly connected to the surface of the limiting ring frame and an arm body inside the guide rail. The guide rail and the arm body are connected by a telescopic rod.

A drive mechanism 8 is provided at the outer end of the drive shaft 9. The adjusting toothed roller 11 is also fitted with the limiting ring frame 16.

[0034] In this embodiment of the utility model, the track platform 2 is set as a rectangular track platform, which is laterally protruding along the outer edge of the base 1. The surface of the track platform 2 is provided with a guide rail corresponding to the punching mounting frame 3. The punching mounting frame 3 is vertically arranged in an "L" shape, and its bottom end is slidably sleeved with the surface of the track platform 2. At the same time, the punching mounting frame 3 and the track platform 2 are driven by a linear motor. The track platform 2 facilitates the sliding adjustment of the punching mounting frame 3 along its surface at the outer position of the base 1. The sliding punching mounting frame 3 facilitates the horizontal movement and adjustment of the punching mechanism 4.

[0035] When punching the pipe fittings, the punching mounting frame 3 moves horizontally along the track platform 2 to adjust to the position of the pipe to be punched, realizing real-time position adjustment punching operation, which greatly improves the operation convenience of the overall device and ensures processing efficiency.

[0036] Two sets of support components 5 are provided, located at both ends of the base 1 and on both sides of the limiting component 6. The support base 12 is trapezoidal, the support platform 13 is rectangular and protruding, and the middle section of its surface is concave in an arc shape. The limiting rollers 14 are longitudinally arranged, with two sets distributed adjacently, located on both sides of the concave position in the middle section of the surface of the support platform 13. The limiting rollers 14 are movably set through the support base. The support base 12 and the movably set limiting rollers 14 achieve the effect of supporting the external pipe fittings, and at the same time, it is convenient for the pipe fittings to be rotated and adjusted according to the punching requirements.

[0037] The limiting seat 7 is stepped, with an opening in its vertical section. The top of the opening is rectangular and the bottom is circular. The mounting cavity 10 is located on the horizontal section surface of the limiting seat 7. The adjusting toothed roller 11, drive shaft 9, and drive mechanism 8 are horizontally arranged. The drive shaft 9 and drive mechanism 8 are both located inside the limiting seat 7. The protective layer 18, guide ring frame 15, and limiting ring frame 16 are stacked from the inside out at the opening positions on the vertical section surface of the limiting seat 7. The surfaces of the protective layer 18, guide ring frame 15, and limiting ring frame 16 are all open. It is rectangular and vertically opened, with a circular opening at the bottom. The protective layer 18 is set as a damping pad layer. The outer surface of the limiting ring frame 16 is provided with a toothed rack corresponding to the adjusting toothed roller 11. The limiting ring frame 16 and the guide ring frame 15 are movably connected by an arc-shaped track. The limiting seat 7 achieves the effect of supporting the external pipe.

The guide ring frame 15 and the limiting ring frame 16 achieve the effect of limiting and supporting the external pipe. The protective layer 18 achieves the effect of reducing the vibration of the pipe.

[0038] Three sets of limiting arms 17 are distributed in a ring along the surface of the limiting ring frame 16. Each set includes a guide rail fixedly connected to the surface of the limiting ring frame 16 and an arm body inside the guide rail. The guide rail and the arm body are connected by a telescopic rod. The inner end of the limiting arm 17 is arc-shaped. The limiting arm 17 achieves the effect of clamping and limiting the external pipes that pass through the protective layer 18, the guide ring frame 15 and the limiting ring frame 16.

[0039] When clamping and positioning the pipe fitting, it is made to pass horizontally through the protective layer 18, the guide ring frame 15 and the limiting ring frame 16. The two ends of the external pipe fitting are supported on the two sets of support components 5. Then the limiting arm 17 is activated to clamp and fix the external pipe fitting. During punching, the adjusting toothed roller 11 rotates under the control of the drive mechanism 8 and forms an engagement with the limiting ring frame 16 from the bottom position. This drives the limiting ring frame 16 to rotate and adjust on the surface of the guide ring frame 15, and then drives the external pipe fitting to rotate and adjust at the same time. Then the punching position is adjusted. The protective layer 18 can effectively reduce the vibration generated during the punching process of the pipe fitting.
