Description
Technical Field
The utility model belongs to the technical field of the electric tube expander and specifically relates to a horizontal electric tube expander limit structure is related to.
Background
In the technical field of heat exchanger and radiator processing, a tube expander is required to expand tubes, so that the assembled fins and copper tubes are combined and fixed together, and finally a heat exchanger or radiator product is formed. The tube expander can be divided into a horizontal tube expander and a vertical tube expander according to different structures. In the existing horizontal tube expander, the product comprises a movable upper door plate and a fixed lower door plate, the product is placed on the lower door plate, and then the upper door plate moves downwards to compress the assembled fin and copper tube product. In order to ensure the position of a product on the lower door plate, two fixed limiting blocks are arranged on the lower door plate, and the product is placed between the two fixed limiting blocks. In the operation process, because the existence of fixed stopper, need remove the product from the top down to the accuracy falls between two fixed stoppers, this structural feeding precision requires highly, and the material loading degree of difficulty is big, and when the material loading deviation appears, the fin can collide with and touch fixed stopper, causes the deformation of fin, leads to the product unqualified. Therefore, the limiting structure of the product needs to be adjusted, so that the feeding is convenient, and the damage of the product caused by the feeding is reduced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a horizontal electric tube expander limit structure solves the current product material loading degree of difficulty big, the problem of vulnerable damage.
The utility model provides a technical scheme that its technical problem adopted is: a limit structure of a horizontal pipe expander comprises a fixed lower door plate and an upper door plate capable of moving up and down, wherein a fixed limit block used for blocking one side of a product is arranged on the lower door plate, and a movable limit block capable of moving back and forth relative to the fixed limit block and acting on the other side of the product is arranged on the upper door plate; the movable limiting block is fixedly installed on the telescopic rod, and one end of the telescopic rod is connected with a driving cylinder which drives the telescopic rod to move back and forth.
Furthermore, the movable limiting block is positioned at the product feeding end of the lower door plate.
In order to ensure the pressing force of the movable limiting block and prevent deformation caused by uneven stress, the upper door plate is provided with two telescopic rods, the movable limiting block is fixed on the two telescopic rods, and a connecting plate is arranged between the telescopic end of the driving cylinder and the telescopic rods.
In order to avoid the stress deformation of the telescopic rod, a group of telescopic rod supporting blocks are arranged on the upper door plate at intervals, and limiting supporting holes for the telescopic rod to pass through are formed in the telescopic rod supporting blocks.
The utility model has the advantages that: the utility model discloses an adjustment to the product stopper sets up the position that fixed stopper is used for restricting heat exchanger or radiator product one side on the door plant down, then presss from both sides tight product to removing through the activity stopper on the last door plant, guarantees that the product location is pressed from both sides tightly when the expand tube. The structure ensures that the product can not contact with the fixed limiting block when being placed on the lower door plate, and then the product is pushed to enable one side of the product to abut against the fixed limiting block on the lower door plate, so that the positioning and conveying are completed. Fixed stopper and activity stopper complex structure can avoid the product to need the accuracy to fall into between two stoppers when the material loading, and the operation degree of difficulty is big, the problem of the damage of colliding with easily, and simultaneously, the product can adopt direct level to push or down put into from last before and push the mode that targets in place again, and material loading is simple and convenient more. The movable limiting block is arranged at the product feeding end, so that the product feeding is facilitated. The movable limiting block is driven by the two telescopic rods, so that the structural stability is better, the acting force of the movable limiting block is more balanced, and the movable limiting block is stressed more evenly and is not easy to deform and damage when a product is clamped tightly, and therefore the service life of the movable limiting block can be prolonged. The telescopic link supporting shoe can avoid the telescopic link atress in long-term use to warp, causes the activity stopper position deviation to appear.
The present invention will be described in more detail with reference to the accompanying drawings and examples.

Detailed Description
Embodiment, as shown in fig. 1 to 3, a limit structure of a horizontal tube expander is used for positioning and clamping a product 100 formed by assembling a fin and a copper tube, and comprises a fixed lower door plate 1 and an upper door plate 2 capable of moving up and down, wherein the product is placed on the lower door plate 1 and is pressed and clamped through the upper door plate 2. In order to determine the position of a product on the lower door plate 1, a fixed limiting block 3 used for blocking one side of the product is fixedly arranged on the lower door plate 1, a movable limiting block 4 which can move back and forth relative to the fixed limiting block 3 and acts on the other side of the product is arranged on the upper door plate 2, and the movable limiting block 4 is positioned at the product feeding end of the lower door plate 1. During the material loading, go up door plant 2 and go upward to open, the product passes through horizontal migration equipment or other equipment and gets into door plant 1 down and impels forward from near-end one side, supports on fixed stopper 3 until one side of product, then goes up door plant 2 and targets in place down, presses at the product upper surface, and movable stopper 4 removes at last, presses at the product opposite side, and the location of product is fixed when realizing the expand tube. After the expand tube is accomplished, the product is loosened in the removal earlier of activity stopper 4, then goes upward door plant 2 and separates with the product, and rethread equipment takes out the product, and this structure can not damage the product at the in-process of last unloading, and goes up unloading convenient operation, can improve the efficiency of going up the unloading.
For guaranteeing the contained angle dynamics of activity stopper 4, activity stopper 4 fixed mounting is on telescopic link 5, and the one end of telescopic link 5 is connected and is provided with the actuating cylinder 6 that drives telescopic link 5 round trip movement. In order to ensure the stress balance of the movable limiting block 4, the upper door plate 2 is provided with two telescopic rods 5, the movable limiting block 4 is fixed on the two telescopic rods 5, namely, the movable limiting block 4 is provided with two fixed points which are respectively fixedly connected with one of the telescopic rods 5. A connecting plate 7 is arranged between the telescopic end of the driving cylinder 6 and the telescopic rods 5, so that the two telescopic rods 5 can be driven to move synchronously through the driving cylinder 6. In order to prevent the telescopic rod from deforming under stress, a group of telescopic rod supporting blocks 8 are arranged on the upper door plate 2 at intervals, and limiting supporting holes for the telescopic rod 5 to penetrate through are formed in the telescopic rod supporting blocks 8.
