In order to achieve the above purpose, the utility model provides a following technical scheme: a hole expanding machine comprises a frame, a workbench is arranged on the frame, the workbench and a support frame are arranged on the frame, the support frame is provided with an oil pressure punch head positioned above the workbench, the oil pressure punch head is connected with a fixing plate, the lower part of the fixed plate is connected with a mounting plate, a plurality of ejector rods are fixedly arranged on the mounting plate, a module is arranged on the workbench, a cushion block is arranged below the module, through holes which are arranged corresponding to the ejector rods are arranged on the module in a penetrating way, the top of the through hole is provided with a placing groove for placing pipe parts and steel balls, the diameter of the through hole is the same as that of the ejector rod, a material discharging groove communicated with the through hole and used for discharging the steel balls is arranged on the cushion block, a metal collecting box is arranged on the workbench, the metal collecting box comprises a box body, wherein a plurality of blocking pieces which extend into the discharging groove and can seal the through holes are arranged on the box body.

Preferably, a through groove communicated with the through hole is formed in the workbench below the cushion block.

Preferably, the support frame is provided with a guide rod, and the guide rod is fixedly connected with the fixing plate.

Preferably, the width of the discharge chute is larger than the diameter of the through hole.

Preferably, the contact end of the ejector rod and the steel ball is an inwards concave spherical cambered surface.

The utility model discloses have following advantage for prior art, its characteristics lie in can once only carrying out the reaming with the hole on a plurality of prefabricated pipe class parts, improve production efficiency. Placing the parts to be processed in the placing grooves, placing steel balls on the parts, pushing the steel balls by the punch to pass through the inner sides of the parts, and falling into the collecting box through the through holes and the discharging grooves. The steel ball is used for quantitatively processing the inner diameter of the part according to the diameter of the steel ball. There is a reasonable error in the inner diameter machining process, which is usually negative, i.e., the actual inner diameter is slightly smaller than the machining standard. The steel ball passes through the pipe parts through the oil pressure action, so that the inner diameter is expanded. The popular explanation is that when steel balls pass through a part, the steel balls rub against the inner wall of the part to scrape the wall thickness, so that the purpose of enlarging the inner diameter is achieved, and the product precision is improved. The advantage is that adopt the hydro-cylinder as guide arm power, and the hydro-cylinder is small, reduces equipment volume, lightens equipment weight. The working principle is simple, the method is suitable for processing small workpieces, and the cost is low. Batch processing, saving labor and improving processing efficiency.

Detailed Description

The present invention will be further explained with reference to the accompanying drawings.

As shown in fig. 1, a hole expanding machine comprises a frame 1, wherein a workbench 2 is arranged on the frame 1, the frame 1 is provided with the workbench 2 and a support frame 3, the support frame 3 is provided with an oil pressure punch 4 positioned above the workbench 2, the oil pressure punch 4 is connected with a fixed plate 5, the lower part of the fixed plate 5 is connected with a mounting plate 6, the mounting plate 6 is fixedly provided with a plurality of ejector rods 7, the workbench 2 is provided with a module 8, a cushion block 9 is arranged below the module 8, the module 8 is provided with a through hole 10 corresponding to the plurality of ejector rods 7 in a penetrating manner, the top of the through hole 10 is provided with a placing groove for placing pipe parts and steel balls 12, the diameter of the through hole 10 is the same as that of the ejector rods 7, the cushion block 9 is provided with a discharging groove 13 communicated with the through hole 10 and used for discharging the steel balls 12, be provided with metal collection box 14 on workstation 2, metal collection box 14 includes box body 15, be provided with the separation blade 16 that a plurality of stretched into in row material groove 13 and can seal through-hole 10 on the box body 15.
