Abstract
The invention relates to a clamping device of a steel pipe grip maker, belonging to a steel pipe grip maker, particularly a clamping device of a grip maker. The clamping device comprises a clamping die box body which is internally provided with at least one group of clamping modules; each group of clamping modules comprise two clamp dies; one sides of two clamping dies are connected with clamping oil cylinders respectively through spacer boards; and the two clamping oil cylinders are oppositely arranged. When the clamping device is used, a bidirectional clamping oil cylinder is started up; the head parts of the oil cylinders are connected with the spacer boards which push the clamping dies for bidirectional clamping; and the clamp force is adjustable by adjusting the working pressure of a hydraulic system. The invention has simple, reasonable and compact structure as well as high grip making precision. As hydraulic bidirectional clamp is set, the core can be oriented accurately when the grip is made and the steel pipe avoids eccentricity during cold drawing. The invention improves the grip-making precision and efficiency of the cold-drawing steel pipe, can be widely applied to making grips of the cold-drawing seamless pipes with middle and large apertures, is particularly suitable for a large-tonnage hydraulic drawbench to produce the seamless steel pipe and has good popularization value.
Description
Technical field
The present invention relates to a kind of steel pipe system machine, relate in particular to the clamping device of a system machine.
Background technology
A steel pipe system machine is applicable to the solid drawn tube industry, especially for middle heavy caliber solid drawn tube industry, is mainly used in the steel pipe head system head of steel pipe before cold-drawn, belongs to seamless steel pipe manufacturing equipment technical field.Existing cold drawn steel control head apparatus is mainly used pneumatic hammer, board drop hammer, rotary forging machine, and its complex structure, a system precision is low, and made steel pipe head pricked extremely, make troubles for the processing of road, back, and made head is longer, and metal loss is big.For middle large diameter steel pipe, existing system head apparatus is powerless.
Summary of the invention
The clamping device of a steel pipe system machine accurately of feeling relieved when purpose of the present invention mainly provides a kind of system.
The object of the present invention is achieved like this: the clamping device of a kind of steel pipe system machine, comprise the clamping die casing, be provided with at least one group in the clamping die casing and clamp module, each group clamps module and comprises two clamping dies, one side of two clamping dies connects clamping cylinder by space bar respectively, and two clamping cylinders are provided with in opposite directions.
During use, start two-way clamping cylinder, the oil cylinder head is joining space bar, and space bar is pushing away that clamping die is two-way to be compressed, and can realize that by the operating pressure of adjusting hydraulic system clamping force is adjustable.The simple and reasonable compactness of the present invention, a system precision height.Because being provided with hydraulic bidirectional clamps, a system time centering accurately, the unlikely off-centre of steel pipe when guaranteeing cold-drawn, the precision and the efficient of cold drawn steel control head have been improved, the system head of heavy caliber cold-drawing seamless pipe in can being widely used in, particularly suitable large-tonnage hydraulic pressure cold drawing machine is produced seamless steel pipe, has excellent popularization to be worth.
Description of drawings
Fig. 1 is a kind of structural representation of the present invention.
Fig. 2 is for clamping the structural representation of module.
The specific embodiment
As shown in Figure 1, be the clamping device of a steel pipe system machine, comprise clamping die casing 18, be provided with two groups in the clamping die casing 18 and clamp module 19, each group clamps module 19 and comprises two clamping die 19-1, as shown in Figure 2.The side of two clamping die 19-1 connects 21, two clamping cylinders 21 of clamping cylinder by space bar 20 respectively and is provided with in opposite directions.Treat that a system steel pipe 1 is clipped between two clamping die 19-1, two clamping cylinders 21 are parallel with the radial direction of waiting to make a steel pipe 1.
Clamping die 19-1 four sides all can be used and suitable different size, and clamping die casing 18 can move forward and backward by bottom and lathe bed mating surface.
Claims (1)
