Description

TECHNICAL FIELD

[0001] The utility model relates to welding equipment field, specifically be a kind of wound protector fixing ring's welding device. BACKGROUND

[0002] In the wound protector production and processing process, the two ends of the wound protector connection need to be welded into a ring by heating fusion.

[0003] In the existing support ring (tpu material) welding process of wound protector, workers need to manually put the two ends of the unwelded product into the equipment clamping jaw slot. The unwelded product itself has strong elasticity, and the two end faces that need to be welded are not absolutely flat. Therefore, it requires workers to have high proficiency to bend the unwelded product into a ring and align the two end faces in the clamping jaw slot.

[0004] If the length of the product placed during processing is too short, it may cause the welded product to be defective and unable to meet the rated tensile strength requirement, resulting in unqualified products. If the length of the product placed is too long, it may cause the welded product to have a flange or burr at the interface, which requires workers to manually trim and flatten, increasing the labor intensity of workers and greatly reducing production efficiency.

[0005] Moreover, the existing equipment heating module design is relatively simple. After long-term use, the heating plate may shake or shift when it is extended, which causes the heating plate position to deviate, resulting in uneven heating of the two end faces welded, thereby affecting the subsequent welding of the two end faces and reducing product qualification rate.

A bottom plate 3b is longitudinally connected on each pair of linear slide rails 3a. A horizontal output cylinder 3c corresponding to the bottom plate 3b is installed on the installation plate 4 at one side of the linear slide rail 3a. The extension and retraction of the horizontal output cylinder 3c drives the bottom plate 3b to move along the linear slide rail 3a.

The extension and retraction of the longitudinal cylinder drives the moving block 3h to move up and down on the guide column 3g.

[0024] An upper clamping jaw 5 is connected at one end of the moving block 3h, and a corresponding lower clamping jaw 5a is connected at one end of the lower fixed plate 3f. The upper and lower clamping jaws 5, 5a are L-shaped structures, and the folding angles of the upper and lower clamping jaws 5, 5a are respectively extended from one end of the moving block 3h and the lower fixed plate 3f by a certain distance. In this way, when the upper and lower clamping jaws 5, 5a on the two horizontal clamping assemblies 3 are closed, there is a certain gap between the two horizontal clamping assemblies 3. The clamping ends of the upper and lower clamping jaws 5, 5a are provided with corresponding clamping grooves 15.

[0025] A front and rear telescopic assembly 6 is provided on the desktop 2 of the other side of the installation plate 4, which comprises a pair of positioning slide rails 6a distributed along the width direction of the installation plate 4, a carriage 6b arranged on the positioning slide rails 6a, a connecting rod 6c connected at one end of the carriage 6b and passing through the installation plate 4, a heating plate 7 connected on one side of the installation plate 4, the heating plate 7 being in communication with the power supply through wires not shown in the figure and generating heat by electricity. A telescopic cylinder 6c corresponding to the bottom plate 6b is installed at one end of the slide rail 6a. The extension and retraction of the telescopic cylinder 6c drives the carriage 6b to move forward and backward on the positioning slide rail 6a, and the forward movement drives the heating plate 7 to extend to the space between the upper and lower clamping jaws 5, 5a of the two horizontal clamping assemblies 3, and the retraction drives the heating plate to retract to the space between the upper and lower fixed plates 3d, 3f of the two horizontal clamping assemblies 3.

The extension length of the tpu strip inserted into the clamping groove 15 of the upper and lower clamping jaws 5, 5a is limited.

[0027] There are also partition plates 11 connected on the desktop 2 at both ends of the mounting plate 4, and a control module 9 with a touch screen is installed on one of the partition plates 11. The transverse output cylinder 3c, the longitudinal cylinder 3e, the telescopic cylinder 6c and the lifting cylinder 8a are in electrical signal control cooperation with the control module 9 through wires not shown in the figure.

[0028] A dust cover 10 is connected on the desktop 2 at the other side of the mounting plate 4, covering the front and rear telescopic assembly 6.

[0029] Working process:

[0030] Firstly, the lifting cylinder 8a drives the limiting plate 8b to extend and insert between the two pairs of upper and lower clamping jaws 5, 5a. At this time, the worker inserts the two ends of the tpu strip to be hot welded into the clamping grooves 15 on the two pairs of upper and lower clamping jaws 5, 5a respectively, so that the end faces of the tpu strip are in contact with the limiting plate 8b, thereby limiting the length of the tpu strip extending out of the upper and lower clamping jaws 5, 5a, and ensuring that the extending distances are consistent. Then the longitudinal cylinder 3e drives the moving block 3h to move downward along the guide column, so that the upper and lower clamping jaws 5, 5a clamp the tpu strip.

[0031] After that, the lifting cylinder 8a drives the limiting plate 8b to retract, the telescopic cylinder 6c outputs to drive the carriage 6b to move forward, and then drives the heating plate 7 to extend forward between the two pairs of upper and lower clamping jaws 5, 5a, and then the transverse output cylinder 3c outputs to drive the bottom plates 3b of the two horizontal clamping assemblies 3 to move inward, so that the end faces of the tpu strip on both sides are tightly attached to the heating plate 7, and the end faces of the tpu strip are heated by electrical heating to soften and have adhesion, and then the output cylinder 3C retracts.

[0032] Then the telescopic cylinder 6c retracts to drive the heating plate 7 to retract to the area between the upper and lower fixed plates 3d, 3f of the two horizontal clamping assemblies 3.

[0033] Then the transverse output cylinder 3c outputs to drive the bottom plates 3b of the two horizontal clamping assemblies 3 to move inward, so that the end faces of the tpu strip are pressed together for a certain period of time, so that the end faces are bonded together, thereby forming a support ring of the wound protector.

[0034] Finally, the longitudinal cylinder 3e retracts the upper and lower clamping jaws 5, 5a to open, and the worker takes out the finished product support ring, and then the output cylinder 3c retracts. The whole device is reset and completed, and the next tpu strip can be hot welded.
