Hydraulic continuous drawing machine

Abstract

The invention discloses a hydraulic continuous drawing machine. The hydraulic continuous drawing machine comprises a framework, a left trolley, a right trolley, two left drawing hydraulic cylinders and two right drawing hydraulic cylinders, wherein the framework is of a vertical structure and is provided with a feeding channel and a discharging channel; the feeding channel is provided with a product drawing mould; each left drawing hydraulic cylinder body is mounted on the left part of the framework; each right drawing hydraulic cylinder body is mounted on the right part of the framework; the left trolley is internally provided with a left clamp; each of the upper part and the lower part of the left clamp is in a wedged shape and is in sliding fit with the left trolley; the left trolley is provided with a left pressing hydraulic cylinder; the right trolley is internally provided with a right clamp; each of the upper part and the lower part of the right clamp is in a wedged shape and is in the sliding fit with the right trolley; the right trolley is provided with a right pressing hydraulic cylinder; the framework is internally provided with public guide rails. According to the hydraulic continuous drawing machine, the framework is of a vertical structure, so that a product is vertically clamped by the left clamp and the right clamp and the machining quality is guaranteed.

Description

technical field [0001] The invention relates to a drawing machine, in particular to a hydraulic continuous drawing machine. Background technique [0002] The structure of the traditional hydraulic continuous drawing machine is complicated, and its frame is a horizontal structure, such as Figure 9 As shown, the traditional hydraulic continuous drawing machine consists of a head seat 26, a mold base 27, a No. 1 drawing cylinder 28, a No. 1 drawing trolley 29, a middle seat 30, a No. 2 drawing cylinder 31, a No. 2 drawing trolley 32, a tail seat 34, etc., between the head seat 26 and the middle seat 30, the No. 1 drawing cylinder 28 of the No. 1 drawing trolley 29 is provided, and the No. 2 drawing cylinder 28 of the No. 2 drawing trolley 32 is provided between the middle seat 30 and the tailstock 34. Extract oil cylinder 31, clamp 34 horizontal direction clamping products, its framework is made up of headstock 26, middle seat 30, tailstock 34 and crossbeam, and its length is ...

AI Technical Summary

Problems solved by technology

[0004] 1. If Figure 10 As shown, the clamp 34 clamps the product 12 in the horizontal direction, and the geometric center of the product 12 moves down when clamped due to the influence of gravity, and the center of the product and the center of the mold are not concentric during drawing, that is, the product 12 is offset downward by δ (δ—the width of the product The distance between the direction centerline and the drawing centerline), making the product prone to defects

[0005] 2. Continuously extruded strip products need to be converted from the horizontal direction to the vertical direction in order to be continuously drawn. Every link will cause the center of the product to not coincide with the center of the drawing due to the influence of gravity, and the product will have serious quality problems. Therefore, it cannot be processed. Rows of parts for continuous drawing

[0006] 3. The frame has a middle seat, the frame length is large, the weight is heavy, the equipment cost is high, and the floor area is relatively large
