Problems solved by technology

Often not only the frictional force suffered by the blank when it rotates on the support plate is very large, but also when the punch is about to complete a circular processing cycle, especially in the final processing of several punching grooves, due to the centrifugal force and the rigidity of the blank Smaller, it is easy to make the radial flakes of the material, so that the spacing between the punched slots becomes uneven
This kind of operation results in a lot of waste and defective products, and the precision of the products cannot meet the requirements
Labor and time-consuming also have a great impact on output

Embodiment 1

[0016] Example 1, such as Figures 1 to 3 As shown, a supporting plate mechanism of a CNC servo high-speed notching machine includes a supporting plate 1, and an actuating cylinder 7 is provided at the lower part of the supporting plate 1. Also be provided with the limiting mechanism that prevents the sheet from being thrown away concentrically with the carrier plate 1, the described limiting mechanism includes a bracket 2, a positioning disc 3 arranged on the bracket 2, and the positioning disc 3 is provided with A group of circumferentially distributed radially movable positioning blocks 4; the ends of the positioning blocks 4 are provided with rollers. The idler wheel is preferably a single row radial ball bearing. The bracket 2 is a fork bracket with an opening, and the cylinder 7 is a thin cylinder.

[0017] In order to adapt to the processing of various sizes of blanks, a group of circumferentially distributed radially adjustable positioning blocks 4 are arranged on th...

Embodiment 2

[0018] Embodiment 2 In order to reduce friction, a group of rolling devices are provided on the positioning plate to make the material rotate smoothly. Specifically, the rolling device is a group of bearings 10 or balls that are radially arranged and circumferentially distributed on the positioning disc. All the other are with embodiment 1.

Embodiment 3

[0019] Embodiment 3, the positioning block 4 is concentrically and uniformly arranged on the positioning plate 3, and there are 6 symmetrical circles, and a group of rollers 11 are arranged at one end of the positioning block 4, and the T set on the positioning block Type bolt 5 adapts to the groove on the positioning disc, and the spacing between the positioning disc and the positioning block is adapted to the size specification of the blank according to the specification adjustment bolt of different blanks. The rolling device is a group of balls that are uniformly distributed on the surface of the positioning plate in the radial direction, thereby reducing friction.

Abstract

The invention discloses a support sheet mechanism of a numerical control servo high-speed puncher, which comprises a support sheet board. The lower part of the support sheet board is provided with an actuating cylinder; and a limit mechanism which is concentric with the support sheet board and avoids sheet fling when processing a material sheet, the limit mechanism comprises a support frame, a positioning plate which is arranged on the support frame, and the positioning plate is provided with a group of positioning blocks in circumference distribution which can be movably adjusted in radial direction; and the end part of the positioning blocks is provided with an idler wheel. The movably adjusting structure is as follows: the positioning blocks or the positioning plate are / is provided with a chute in radial direction, and a bolt passes through the chute and connects the positioning blocks and the positioning plate firmly. The positioning plate is also provided with a group of rolling devices which enable the material sheet to rotate smoothly. By adopting the adjustable limit structure and the rolling devices, when the puncher punches the last punching grooves, sheet fling of the material sheet is avoided, and the rotary friction of the material sheet is reduced. The material sheet can be punched more accurately, thus improving the accuracy quality of the punching material sheet. And moreover, radial adjustment can be carried out according to the size of the processed material sheet.

Description

technical field [0001] The invention relates to a supporting plate mechanism of a numerically controlled servo high-speed notching machine, in particular to a supporting plate mechanism of a numerically controlled servo high-speed notching machine for processing silicon steel sheets of electric motors. Background technique [0002] At present, only a simple supporting plate is used in the supporting plate mechanism of the punching machine for processing silicon steel sheets of electric motors, and only a cylinder is used to lift the blanking sheet to complete the notching process when completing a circular processing cycle of the blanking sheet. Often not only the frictional force suffered by the blank when it rotates on the support plate is very large, but also when the punch is about to complete a circular processing cycle, especially in the final processing of several punching grooves, due to the centrifugal force and the rigidity of the blank If the size becomes smaller,...
