Abstract
The utility model discloses a lift apparatus of diameter enlarging machine, comprising a lower die, a worktable and a roller, which is characterized in that the lift apparatus is composed of two parts of a feed mechanism and a discharge mechanism, four feed mechanisms and four discharge mechanisms are distributed on the worktable in full-length direction, the feed and the discharge are arranged in interval, the feed mechanism is composed of a hydraulic cylinder and a lift sleeve, the discharge mechanism is composed of a hydraulic cylinder, a roller and a discharge guide frame. The feed mechanism and the discharge mechanism are acting alternately according to the electrical instructions, when feeding, the cylinder of the feed part is acting, and the lift head is lifted to lift the workpiece to depart from the lower die, so that the feed is completed by other apparatus. When process of the workpiece is completed, the cylinder of the discharge part is acting, the discharge roller lifts the workpiece to depart from the lower die, and the workpiece is transmitted out of the machine tool by a chain apparatus, so that the discharge function is completed. The utility model has the advantages that the guide part is arranged at the bottom part of the lower die to act synchronously with the cylinder, so that the cylinder influenced by the bending moment, and the service life is increased, and the friction of the lower die template is avoided to reduce the abrasion of the workpiece.
Description
Technical field
Go out the expanding machine jacking mechanism of work stone after the feeding of steel plate and steel pipe machined when the utility model belonged to the hole enlargement steel tube forming.
Background technology
Adopt the cross connection type jacking system in the past, be installed in the external position of counterdie width, stride across counterdie, supporting material roller must be divided into counterdie and cuts many segments, and the counterdie difficulty of processing increases like this, the fixing difficulty of counterdie, the gap of counterdie produces damage to workpiece, forms defective easily.
Summary of the invention
It is easily fixing that the purpose of this utility model provides a kind of counterdie, and workpiece is produced the little expanding machine jacking mechanism of damage.
For achieving the above object, solution of the present utility model is: a kind of expanding machine jacking mechanism, by counterdie, workbench, rolling roller forms, described this jacking mechanism is made up of feeding mechanism and discharging mechanism two parts, four feeding mechanisms of described workbench total length direction distribution, four discharging mechanisms, charging and discharge room are every layout, described this jacking mechanism above-below direction passes counterdie 6, feeding mechanism is by hydraulic cylinder 3, jack-up sleeve 1 is formed, jack-up sleeve 1 is contained in the top of hydraulic cylinder 3 pistons, hydraulic cylinder 3 is fixed on the workbench 7, described discharging mechanism is by hydraulic cylinder 3, roll roller 5, discharging leading truck 2 is formed, described rolling on the crossbeam that roller 5 is contained in hydraulic cylinder 3 tops, and described discharging leading truck 2 is contained in the both sides of oil cylinder by the axis of guide 4, described hydraulic cylinder 3 is fixed on the workbench 7, and described workbench 7 tops also are equipped with counterdie 6.
Feeding mechanism and discharging mechanism are by electric instruction alternating movement, and when feeding, feeding part cylinder action ejects head and rises, and workpiece is held up leave counterdie, finishes feeding by other mechanism.After workpiece machined, output section cylinder action, discharging running roller held up workpiece and leave counterdie, by link chain mechanism workpiece are sent lathe, finish discharging functions.Targeting part is contained in the counterdie bottom, with the oil cylinder synchronization action, makes oil cylinder not be subjected to moment of flexure, increases the service life.Avoid friction, alleviate abrasion workpiece to the counterdie template.Double round piece realized feeding.Because no longer segmentation of counterdie makes component shaping desirable more, avoids occurring the impression defective.

The specific embodiment
As shown in Figure 1 to Figure 3, this expanding machine jacking mechanism, by counterdie, workbench, rolling roller forms, described this jacking mechanism is made up of feeding mechanism and discharging mechanism two parts, four feeding mechanisms of described workbench total length direction distribution, four discharging mechanisms, charging and discharge room are every layout, described this jacking mechanism above-below direction passes counterdie and compensation mechanism, feeding mechanism is by hydraulic cylinder 3, jack-up sleeve 1 is formed, jack-up sleeve 1 is contained in the top of hydraulic cylinder 3 pistons, hydraulic cylinder 3 is fixed on the workbench 7, described discharging mechanism is by hydraulic cylinder 3, roll roller 5, discharging leading truck 2 is formed, described rolling on the crossbeam that roller 5 is contained in hydraulic cylinder 3 tops, and described discharging leading truck 2 is contained in the both sides of oil cylinder by the axis of guide 4, described hydraulic cylinder 3 is fixed on the workbench 7, and described workbench 7 tops also are equipped with counterdie 6.When steel plate entered, the jack-up cylinder action with steel plate jack-up, left the counterdie template, when especially in the end several roads of steel pipe fold, steel pipe must be held up, and just can finish the feeding action.During discharging, the charging oil cylinder falls, and the discharging oil cylinder rises, and makes steel pipe be supported on the U type and rolls on the roller, and link chain mechanism is pulled out steel pipe.Hydraulic cylinder is upward through workbench compensation mechanism and grooved counterdie at upper and lower, and the part that install the inside is many, and the space is little.Make oil cylinder cause many difficulties aspect fixing, oil-feed, fuel-displaced, the push rod guiding like this.
