Abstract

The utility model relates to equipment mainly used for connecting hoses, which is characterized in that a sliding base (2) is arranged on a large vertical plate (1); a mold base (4) is arranged on the sliding base (2); a half mold base (5) and a half mold base (6) can slide respectively in a T-shaped groove of a cushion block (12); four mold bases (3) are lapped respectively between the mold base (4) and the half mold base (5) and between the half mold base (6) and a mold (7) under the action of spring tension; and the large vertical plate (1) is connected to two columns (9) and connected with a piston of a cylinder. When the piston of the cylinder (8) moves down, the two columns (9) drive the large vertical plate (1) to simultaneously move so as to drive the sliding base (2) to slide down, i.e., the half mold base (5) and the half mold base (6) are overlapped into a whole mold base. With the piston of the cylinder (8) continuing to move down and under the action of the large vertical plate (1) and the V-shaped inclined plane of the sliding base (2), the mold base (4), the half mold base (5) and the half mold base (6) are pushed to contract radially, the mold bases (3) are driven to concentrically contract simultaneously, and the mold base (4) drives the crimping mold (7) on the mold base (4) to contract radially, thereby realizing the crimping of hoses. Due to the adoption of the new mold-dividing technique, for the crimping of multi-bending air conditioning hoses, the precision of hose crimping is enhanced, the problem of deformation of side opening crimping is absolutely solved, the operation is convenient, safe and reliable, the production efficiency is high, and the labor intensity is reduced.

Description

A kind of pair of column merotype withheld machine

Technical field:

The utility model relates to and is used for the equipment that flexible pipe connects, and especially contains hydraulic tube, air-conditioning pipes such as big flange, many bend pipes.

Background technology:

At present, general sebific duct is withheld machine and is adopted single annular cylinder structure or four oil cylinders, promotion monocline face or double inclined plane structures, and to realize the withholding connection sebific duct, its advantage is a compact conformation, and volume is little, buckle press is big; But its oil cylinder stroke is big, and its opening degree is restricted, and is unfavorable for being connected of union elbow and flange-type joint;

It is the framework of a sealing that another kind is withheld its frame of machine, and its advantage is that to withhold the machine opening degree big, and cavity length is little, therefore, is fit to withholding of flexible pipe such as big caliber sebific duct, bend pipe and dirt orchid and is connected; But because frame has adopted frame structure, thus processing difficulties, cost is higher, and frame structure has also limited the size of oil cylinder simultaneously, and buckle press further raising is restricted;

Also have a kind of side opening formula to withhold withholding of the flexible pipe that machine can be withheld various terminal, particularly union elbow, but owing to adopted relatively poor " bow " shape frame structure of rigidity, therefore, its buckle press is little, generally only is used for the connection of withholding of automotive air conditioning hose.

Summary of the invention:

The purpose of the utility model: overcome existing weak point of withholding machine; Provide the low hose assembly of a kind of processing cost simple in structure to withhold machine; Be beneficial to being connected of union elbow and flange-type joint; Satisfy needs, particularly oil, chemical industry, naval vessel that the hydralic hose assembly produces, withhold the requirement that is connected with the large-scale sebific duct of other heavy duty industrial; It adopts the new technology of branch mould, and the location is convenient, the restriction that is not bent, and easy to operate, labour intensity is little, and production efficiency is high, has thoroughly overcome the problem of pressure distortion.

The utility model is mainly formed by withholding part and hydraulic system; It is as shown in Figure 1 wherein to withhold part, mainly is made up of big riser (1), sliding seat (2), the first half module seat (5), the second half module seat (6), two column (9), block (11) and cushion block (12) etc.It is characterized in that: sliding seat (2) is installed on the big riser (1); Die holder (4) is installed on the sliding seat (2); Half module seat (5) and half module seat (6) can slide in the T type groove of cushion block (12) respectively; Other has four die holders (3) under the tension force effect of spring, to connect respectively at die holder (4) and half module seat (5), and between die holder (6) and the half module seat (7), big riser (1) is connected in two columns (9) and upward and with oil cylinder piston links to each other.When the piston of oil cylinder 8 moved downward, two columns 9 drove big riser 1 and move simultaneously, thereby it is downward to drive sliding seat 2; Being about to that half module seat 5 overlaps with half module seat 6 is a complete die holder, along with the piston of oil cylinder 8 continues to move downward, under the effect on big riser 1 and the V-type inclined-plane of sliding seat 2; Promoting die holder 4 radially shrinks with half module seat 5, half module seat 6; Drive die holder 3 again and shrink with one heart, die holder 4 drives again withholds mould 7 radial contraction on it, realizes withholding of sebific duct.

Advantage of the utility model and beneficial effect: owing to adopt to divide a mould new technology,, improved the precision that sebific duct is withheld for withholding of many bendings air-conditioning pipe etc.; Thoroughly change side opening and withheld the problem of distortion, easy and simple to handle, safe and reliable; Production efficiency is high, has alleviated labour intensity.

Description of drawings:

Fig. 1 is the structural representation when withholding machine and opening, and the implication of label symbol is:

Big riser 1 sliding seat 2 die holders 3

Die holder 4 half module seats 5 half module seats 6

8 pairs of columns 9 of mould 7 oil cylinders

Micro-adjusting mechanism 10 blocks 11 cushion blocks 12

Fig. 2 is in and withholds view for withholding machine

The specific embodiment:

Fig. 1, Fig. 2 showed the utility model merotype withhold machine from open state to the course of work of withholding state.

When giving oil cylinder 8 oil-feeds, fluid promotes oil cylinder piston under pressure and moves downward, and two columns 9 drive big riser 1 and moves simultaneously, and then drive sliding seat 2 moves downward, and when half module seat 5 overlaps with half module seat 6, gets into and is about to withhold state; The piston of oil cylinder 8 continues to move downward; Under the V-type ramp effect of big riser 1 and sliding seat 2; Promoting die holder 4 radially shrinks with half module seat 5, half module seat 6; Drive die holder 3 simultaneously and shrink with one heart, die holder 3, die holder 4 and half module seat 5, half module seat 6 drove and withheld the mould radial contraction on it this moment, accomplished withholding of sebific duct thus.

When withholding end, the solenoid directional control valve switching-over, oil cylinder 8 rollback hydraulic fluid port oil-feeds, piston is upwards done the rollback motion; Die holder 3, die holder 4 and half module seat 5, half module seat 6 are done centrifugal motion under the tension force effect of compression spring; Drive mould 7 simultaneously and make synchronous centrifugal motion.The piston of oil cylinder 8 continues to move upward fast, because the barrier effect of block 11, die holder 3, die holder 4 and half module seat 5, half module seat 6 no longer open, and take off hose assembly, accomplishes the process of withholding.

The machine of withholding is furnished with the mould of withholding of different size, can realize withholding of different tube diameters sebific duct and joint.
