Description

Technical Field

[0001] This utility model relates to the field of auxiliary tools for evaporator production, specifically to a wire feeding tool for wire tube heat exchangers. Background Technology

[0002] Currently, such as Figure 4 As shown, one type of evaporator includes a tube body 98, which is bent into a flat plate shape. To stabilize the shape of the tube body 98, support bars 99 are arranged and welded on the flat tube body. The support bars 99 are round steel rods with a diameter of 2 mm to 3 mm. Refrigerant can be transported through the tube body 98. In the process of welding the support bars 99 to the tube body 98, a fixture is currently used to position the tube body 98. The fixture is equipped with positioning slots. The support bars 99 are stacked in a tray 97. Each support bar 99 is placed into the positioning slot by hand. Then, the support bars 99 are welded to the tube body 98 using resistance welding. However, it is time-consuming to place the support bars 99 one by one from the tray 97 by hand. Although some skilled workers can arrange the support bars 99 quickly, it requires a high level of skill from the workers and the work efficiency is not high. Therefore, it is necessary to make an auxiliary tool that can quickly pick up the support bars. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a wire feeding tool for wire tube heat exchangers, which is beneficial to improving work efficiency.

[0004] The objective of this utility model is achieved through the following technical solution.

[0005] The present invention discloses a wire feeding tool for a wire tube heat exchanger, comprising a plate body, wherein a transverse groove for accommodating a support bar is formed at the bottom of the plate body, the transverse groove being arranged longitudinally and extending transversely through the plate body, and a longitudinal groove is formed at the bottom of the plate body, wherein a magnetic strip for holding the support bar is adapted to be provided in the longitudinal groove, and the longitudinal groove extending longitudinally through the plate body.

[0006] Preferably, the transverse groove is located on the lower side of the magnetic strip.

[0007] Preferably, the magnetic strip is a rubber magnetic strip.

[0008] Preferably, the magnetic strip is bonded to the bottom of the longitudinal groove.

[0009] Preferably, a handle is mounted on the top of the plate.

[0010] Preferably, the plate is an aluminum plate.

[0011] Compared with the prior art, the advantages of this utility model are as follows: by setting a horizontal groove for accommodating the support bar at the bottom of the plate, the horizontal groove is arranged longitudinally and penetrates the plate horizontally, and a vertical groove is formed at the bottom of the plate, in which a magnetic strip for holding the support bar is adapted, and the vertical groove penetrates the plate vertically, the worker can use the support bar wire laying tool of this utility model to pick up multiple support bars at the same time, thereby improving work efficiency.

[0016] Labeling explanation: Plate 1; Longitudinal groove 11; Horizontal groove 101; Magnetic strip 2; Handle 3; Support bar 99; Tube 98; Plate 97. Detailed Implementation

[0017] The present invention will now be further described with reference to the accompanying drawings.

[0018] The evaporator support bar picking tool of this utility model, such as Figure 1 and Figure 2 As shown, the system includes a plate 1. A transverse groove 101 for accommodating a support bar 99 is formed at the bottom of the plate 1. The transverse grooves 101 are arranged longitudinally and extend laterally through the plate 1. The bottom of the transverse grooves 101 can be arc-shaped to accommodate the cylindrical support bar 99. A longitudinal groove 11 is formed at the bottom of the plate 1. A magnetic strip 2 for holding the support bar 99 is fitted inside the longitudinal groove 11. Specifically, as shown... Figure 2 As shown, the width of the magnetic strip 2 is adapted to the width of the longitudinal groove 11 (i.e., Figure 2 The dimension “W” in the groove 11 is such that the magnetic strip 2 can be positioned. Figure 1 and Figure 2 The longitudinal groove 11 shown extends longitudinally through the plate 1.

[0019] like Figure 3 As shown, the support bars 99 are stacked in the plate 97. The worker presses the plate 1 firmly onto the stack of support bars, and then moves it longitudinally (as shown). Figure 3(As indicated by the arrow) By rubbing the plate 1, the magnetic attraction of the magnetic strip 2 to the support strip 99 and the downward pressing action of the plate 1 cause the support strip 99 to enter the transverse groove 101. Due to the aforementioned rubbing action, each transverse groove 101 is aligned with the support strip 99, thus preventing the transverse groove 101 from being empty. The worker then lifts the plate 1, and the picking tool of this utility model picks up multiple support strips 99 at once. The worker then moves the support strips 99 to the evaporator welding fixture. During this process, the magnetic strip 2 holds the support strips 99 to prevent them from falling. Afterward, the support strips 99 are aligned with the evaporator welding fixture. The plate 1 is moved downwards by adjusting the positioning slots. Since the spacing of the horizontal grooves 101 is the same as the spacing of the positioning slots, each support bar 99 simultaneously enters its corresponding positioning slot. Then, the plate 1 is flipped to the side. Because the ends of the support bars 99 are supported by the bottom of the positioning slots, the bottom of the positioning slots prevents the support bars 99 from rotating with the plate 1 when the plate 1 is flipped, causing the support bars 99 to swing away from the horizontal grooves 101. The magnetic attraction of the magnetic strip 2 to the support bars 99 decreases significantly. Then, the plate 1 is moved upwards, and each support bar 99 stops in its positioning slot. As can be seen from the above, by using the support bar wire-laying tool of this invention, multiple support bars 99 can be picked up simultaneously, which is beneficial to improving work efficiency and does not require high operator skill. Since the longitudinal groove 11 runs through the plate 1, the magnetic strip 2 can be installed entirely into the longitudinal groove 11, which facilitates the easy installation of the magnetic strip 2.

[0020] Furthermore, such as Figure 1 As shown, the horizontal groove 101 is located on the lower side of the magnetic strip 2. That is to say, the depth of the vertical groove 11 (in the vertical direction) is greater than the depth of the horizontal groove 101, so that when the support 99 contacts the bottom of the horizontal groove 101, the support 99 will not touch the magnetic strip 2, thereby avoiding the magnetic strip 2 from being dented or scratched by the support 99. Specifically, when the support 99 is close to the bottom of the horizontal groove 101, there is a gap of 0.1 mm to 0.2 mm between the support 99 and the magnetic strip 2.

[0021] Furthermore, the magnetic strip 2 is a rubber magnetic strip, which is existing technology. For example, one can refer to the "Colored Rubber Magnetic Strip" in Chinese Utility Model Patent Publication No. CN2378216Y. Because rubber magnetic strips are easy to cut, they are easily cut into shapes that fit the longitudinal groove 11. For example... Figure 2 As shown, the number of longitudinal grooves 11 is set to two, which helps to increase the range of magnetic strip 2 attracting support strip 99.

[0022] Furthermore, the magnetic strip 2 is bonded to the bottom of the longitudinal groove 11, which facilitates the installation of the magnetic strip 2 and avoids the need to drill holes in the magnetic strip 2 for screw installation.

[0023] Furthermore, such as Figure 1As shown, a handle 3 is installed on the top of the plate 1, so that the worker can hold the handle 3 and press the plate 1 onto the support bar 99 inside the plate 97. The two ends of the handle 3 can be connected to the plate 1 by corresponding screws.

[0024] Furthermore, the plate 1 is made of aluminum, which is beneficial for the plate 1 to have greater rigidity, but avoids the plate 1 being too heavy and causing inconvenience in operation.
