Description

Technical Field

[0001] The utility model relates to the technical field of hole expansion molds, in particular to a coil shell sheet hole expansion mold. Background Art

[0002] Hole expansion is a forging process that enlarges the bottom of the drilled hole or the bottom of certain types of foundation piers in order to increase the load-bearing area, reduce the wall thickness of the hollow blank and increase its inner and outer diameters.

[0003] Chinese patent CN220838041U discloses a hole reaming device for precision mold processing, including a processing table, a hole reaming mechanism, a material collection mechanism and an installation mechanism, wherein the hole reaming mechanism is located above the processing table, the material collection mechanism is located inside the processing table, and the installation mechanism is located below the processing table. The utility model drives the protective cover shell to move up and down through an electric cylinder, and the servo motor drives the hole reaming drill to rotate, and falls on the hole reaming table to reame the workpiece, the fixed groove places the workpiece, and the electric push rod drives the clamping block to extend and retract to clamp the workpiece, which can prevent the workpiece from slipping and affecting the hole reaming quality. The hole reaming debris is received through the drop hole, and the debris falls into the collection drawer through the collection groove. The storage situation is checked through transparent glass, and the drawer handle pulls out the collection drawer for waste cleaning. The processing table is supported by a support block, and the support seat improves the stability of the support. The fixing bolt passes through the fixed screw groove to facilitate the threaded connection of the support seat, which is convenient for installation and fixation.

[0039] Example

[0040] like Figure 1-5 As shown, the present embodiment provides a coil shell sheet reaming die, comprising: an upper die 1 and a lower die 2, the upper die 1 comprising: a connecting seat 11 for connecting to a processing machine tool and a reaming drill bit 12 arranged on the connecting seat 11, the lower die 2 comprising: a base 21, a support seat 22 arranged on the base 21, a lateral positioning assembly 23 arranged on one side of the support seat 22, a plurality of longitudinal clamping assemblies 24 for fixing the workpiece arranged on the adjacent side of the support seat 22, and a chip removal assembly 25 arranged on the other side of the support seat 22, the lateral positioning assembly 23 and the longitudinal clamping assembly 24 respectively limit and fix the sheet in the horizontal and vertical directions, so that the sheet is more stable and firm, and will not move easily, which can effectively avoid the sheet from breaking during processing, and the chip removal assembly 25 makes the surface of the sheet cleaner and tidier, and waste chips will not fall everywhere, and can be better recycled and reused.

[0041] Among them, the lateral positioning assembly 23 includes: a bracket 231 arranged close to the support seat 22, a power member 232 arranged on the bracket 231, and a clamping member 233 arranged at the output end of the power member 232. The power member 232 provides power to drive the clamping member 233 to move back and forth left and right, that is, to limit and fix the material sheet in the horizontal direction. It is simple to operate, easy to use, and has high work efficiency.

[0042] At the same time, the longitudinal clamping assembly 24 includes: a pillar 241 vertically arranged on the base 21, a cross bar 242 horizontally arranged at the top of the pillar 241, and a pressure plate 243 arranged below the cross bar 242. The pressure plate 243 is used to clamp the sheet and fix the sheet in the vertical direction, thereby further increasing the stability of the sheet. The structure is simple, the disassembly and assembly are convenient, and the use cost is low.

[0043] In this embodiment, the chip removal assembly 25 includes: a receiving platform 251 fixedly connected to the upper surface of the base 21, a driving member 252 arranged on the receiving platform 251, and a cleaning member 253 arranged at the output end of the driving member 252. The cleaning member 253 is arranged opposite to the support seat 22, that is, the cleaning member 253 is arranged above the workpiece, and the height of the receiving platform 251 is adjustable to adjust the position of the cleaning member 253 so that it can be in the best cleaning state to adapt to the cleaning of sheets of different thicknesses. The driving member 252 provides power to drive the cleaning member 253 to move horizontally back and forth, so as to clean the waste chips on the surface of the sheet. It is simple to operate and easy to use.

[0044] In this embodiment, the pillar 241 includes: a first straight rod 2411 fixedly connected to the base 21, a second straight rod 2412 slidably connected to the first straight rod 2411, and a locking member 2413 arranged on the second straight rod 2412. The position of the second straight rod 2412 is controlled by the locking member 2413, and then the overall height of the pillar 241 is adjusted to adapt to the material sheets of different thicknesses. It has a simple structure and is easy to operate.

[0045] In this embodiment, a collecting groove 26 is arranged on the opposite side of the chip removal assembly 25, and the collecting groove 26 is arranged close to the edge of the support seat 22. The collecting groove 26 is used to collect waste chips generated after processing by the reaming drill bit 12 to avoid messy splashing of waste chips. Centralized processing can make it more convenient and quick to recycle and reuse them.

[0046] In this embodiment, the shape of the clamping member 233 is adapted to the workpiece to be processed. The workpiece is preferably circular, and the shape of the clamping member 233 is arc-shaped, so that the clamping member 233 can quickly clamp the workpiece and is easy to use.

[0047] Of course, a groove 221 is provided in the middle of the support seat 22, and the reaming drill bit 12 is provided directly above the groove 221, and the size of the groove 221 should be larger than the maximum diameter of the reaming drill bit 12, that is, the groove 221 is used to accommodate the reaming drill bit 12 that moves downward during work to avoid the reaming drill bit 12 from being damaged by collision, thereby protecting the reaming drill bit 12 and extending the service life of the reaming drill bit 12.

[0048] In addition, the diameter of the drill body of the reaming drill bit 12 increases successively along its axial direction, that is, there are multiple reaming sizes on one reaming drill bit 12, which can process multiple pieces that need holes of different sizes respectively, reducing the number of times the reaming drill bit 12 is replaced and improving work efficiency.

[0049] The working process of this embodiment is: first, the material sheet is placed on the support seat 22, and then the clamping member 233 starts to move in the horizontal direction and clamps the material under the action of the power member 232. After clamping, the pressure plate 243 moves down to press the material, and then the connecting seat 11 starts to move down, and the reaming drill bit 12 starts to work. After the reaming is completed, the connecting seat 11 is reset. At this time, the cleaning member 253 starts to work and transfers the waste chips to the collection tank 26. After cleaning is completed, the pressure plate 243 and the clamping member 233 are reset in turn, and the material can be taken out at this time.

[0050] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
