Non-woven needle body cold heading and reducing equipment and process

Abstract

The invention belongs to the technical field of non-woven needle machining, and particularly relates to non-woven needle body cold heading and reducing equipment. The non-woven needle body cold heading and reducing equipment comprises a machine base and a workbench fixed to the upper portion of the machine base in a threaded connection mode, wherein a supporting frame is fixedly arranged on the workbench, a cold heading device is fixedly arranged in the middle position of the inner side of the top end of the supporting frame, and the top of the workbench is in sliding connection with a transverse moving mechanism. Transverse and longitudinal movement is conducted according to the screw rod transmission principle, a clamping mechanism for clamping a workpiece is driven to horizontally moveon the workbench in the X-axis direction and the Y-axis direction till the clamping mechanism is located under the cold heading device, adjustability is high, the cold heading device can meet the clamping and positioning requirements of workpieces of different sizes, when the workpiece is clamped and fixed, the clamping mechanism can be moved to any position in the stroke of the transverse movingmechanism and a longitudinal moving mechanism in the effective area of the workbench, the workpiece can be conveniently clamped and fixed, and the moving limitation is reduced.

Description

technical field [0001] The invention belongs to the technical field of non-woven lancet processing, and in particular relates to a non-woven lancet needle body cold heading diameter reduction equipment and a process. Background technique [0002] The cold heading process is a forging method that uses a mold to upset a metal bar at room temperature, and is usually used to manufacture the heads of screws, bolts, rivets, etc. Cutting can be reduced or replaced. The forging material can be copper, aluminum, carbon steel, alloy steel, stainless steel and titanium alloy. Cold heading is mostly carried out on a special cold heading machine, on which the cutting, heading, accumulation, forming, chamfering, thread rolling, diameter reduction and edge trimming can be completed in sequence. [0003] Non-woven needles are one of the important workpieces used to produce needle-punched non-woven fabrics. During the production and processing of non-woven needles, cold pier equipment is n...

Problems solved by technology

[0004] China Patent Network has proposed a stamping cold heading equipment (publication number is CN111113158A). This patented technology solves the problem of frequent removal and re-clamping of workpieces and low processing efficiency. However, in the cold heading equipment proposed by the patented technology The structure of the workpiece clamping and positioning device is relatively simple, and it can only clamp and position some large workpieces with a relatively neat shape and structure. When clamping small workpieces such as non-woven needles, there is a problem of clamping instability. , and the workpiece clamping device in this patent can only realize lateral movement, but cannot move longitudinally, which has limitations in use
