Description
Technical Field
The utility model belongs to the technical field of machining, specifically speaking especially relates to a carbide thin wall nozzle anchor clamps for pressed compact.
Background
The processing technology of the existing hard alloy thin-wall nozzle pressed compact during processing mainly comprises the following steps: the excircle processing method comprises the steps of turning a blank pressing body into a cylindrical blank → drilling a prefabricated hole → turning a straight hole → turning a plane and turning the shape of the excircle of the inner hole of the other end of the product, wherein one end of the product is clamped on a lathe, and the shape of the excircle of the inner hole of the other end of the product is turned on the plane (the main purpose of turning the excircle is to reduce the weight of the pressed blank and prevent the pressed blank from being too heavy and difficult to jack up in the next procedure or prevent the pressed blank from being clamped by too large clamping force. At present, manufacturers lack an effective clamp when applying the processing technology to process hard alloy thin-wall nozzle pressed compacts so as to cause the following defects when adopting the processing mode, firstly, in order to ensure the quality of the pressed compacts, the processing allowance is large enough, secondly, products are easy to be damaged by clamping, once the products are damaged by clamping, the appearance of the pressed compacts is difficult to reflect, and the quality problems of product cracks, block falling and the like can be presented after sintering.
Disclosure of Invention
The utility model aims at providing a carbide thin wall nozzle is anchor clamps for pressed compact to overcome among the prior art carbide thin wall nozzle pressed compact and add the defect that lacks an effectual anchor clamps.
The utility model discloses an adopt following technical scheme to realize: the utility model provides a carbide thin wall nozzle anchor clamps for pressed compact, includes the anchor clamps body, the anchor clamps body includes the base, and base top surface installation fixed axle, fixed axle include conical surface and vertical face, and fixed axle top installation top cap, the diameter of top cap are greater than the diameter of fixed axle top surface, and the diameter of base top surface is greater than the diameter of fixed axle bottom surface.
Furthermore, a bolt hole is formed in the top of the fixed shaft, a through hole is formed in the top cover, the fixed shaft and the top cover are fixedly connected through a bolt, and the bolt penetrates through the through hole and is matched with the bolt hole.
Furthermore, an annular slag discharge groove is formed in the position, close to the fixed shaft, of the top surface of the base.
Furthermore, rubber pads are arranged on the bottom surface of the top cover and the top surface of the base.
Compared with the prior art, the beneficial effects of the utility model are that: the utility model discloses can realize the high quality processing of carbide thin wall nozzle pressed compact, greatly reduce blank machining allowance simultaneously, the blank is difficult to be hindered by the clamp, realizes low-cost, the high efficiency production of carbide nozzle product.

Detailed Description
The present invention will be further explained with reference to the accompanying drawings.
The utility model provides a carbide thin wall nozzle anchor clamps for pressed compact, includes the anchor clamps body, the anchor clamps body includes base 1, 1 top surface installation fixed axle of base, and the fixed axle includes conical surface 2 and vertical face 3, and fixed axle top installation top cap 4, the diameter of top cap 4 are greater than the diameter of fixed axle top surface, and the diameter of 1 top surface of base is greater than the diameter of fixed axle bottom surface.
The utility model discloses at first overlap the carbide thin wall nozzle pressed compact on the fixed axle at the during operation, make the bottom surface of pressed compact and base 1's top surface contact, then install top cap 4 at the fixed axle top, make the pressed compact fix between base 1 and top cap 4, the shape of fixed axle is the same with the shape of the hole of pressed compact, the pressed compact only needs to process can sheathe anchor clamps in after hole die cavity and the flush end face, the pressed compact clamping is on anchor clamps, can directly process the pressed compact excircle and greatly reduce the machining allowance of excircle part after pressing from both sides tightly, no matter its inner hole die cavity part or two terminal surfaces all receive the force simultaneously, thereby can avoid the problem of local stress concentration.
The top of the fixed shaft is provided with a bolt 5 hole, the top cover 4 is provided with a through hole, the fixed shaft and the top cover 4 are fixedly connected through the bolt 5, and the bolt 5 penetrates through the through hole and is matched with the bolt 5 hole.
The utility model discloses a bolt 5 makes top cap 4 and pressed compact in close contact with.
An annular slag discharging groove 6 is formed in the position, close to the fixed shaft, of the top surface of the base 1.
The slag discharge groove 6 mainly aims at preventing the situation that the turning material has no place to discharge chips during the processing of the pressed compact and causes the inner hole clamping material to drop the edge even to influence the product quality.
Rubber pads are arranged on the bottom surface of the top cover 4 and the top surface of the base 1.
Equal rubber pad of bottom surface and the 1 top surface of base of top cap 4, the cushioning effect of rubber pad has reduced because the too big risk that leads to the pressed compact to press from both sides the injury of clamp force.
The utility model relates to a high density graphite anchor clamps, because the pressed compact surface finish is not high when the assembly, fixed axle and pressed compact hole die cavity should leave certain clearance and make things convenient for both assemblies.
