Description

Technical Field

[0001] This utility model relates to a condenser tube cutting and enlarging platform. Background Technology

[0002] Condenser tubes are crucial components in radiators, requiring bending, punching, and reaming processes during manufacturing. Maintaining the integrity of the condenser tube's sidewalls after bending is essential for radiator efficiency. Existing processing equipment makes hard contact with the condenser tube during punching, easily damaging its sidewall integrity and even flattening it. For example, CN217964289U discloses a condenser tube punching mechanism for finned radiators, which increases the clamping area of ​​the fixture to avoid hard contact and reduce localized stress on the condenser tube. However, the contact area between the fixture and the condenser tube is still a hard part, which may cause a hard collision during clamping, damaging the condenser tube's integrity. Utility Model Content

[0003] To solve the above-mentioned technical problems, this utility model provides a condenser tube cutting and enlarging platform.

[0004] This utility model is achieved through the following technical solution.

[0005] This utility model provides a condenser tube cutting and reaming platform, including an X-axis worktable, a Y-axis worktable, a fixture, and a cutting tool. The Y-axis worktable and the fixture are respectively mounted above the X-axis worktable. A reaming device is installed on the Y-axis worktable. The fixture includes two sleeves, which are semi-cylindrical. The two sleeves are opposite each other and are respectively mounted on the push rods of two fixture cylinders. The axial ends of the sleeves are respectively machined with a clamping cavity and a reaming cavity. The clamping cavity is an arc groove with a diameter equal to that of the condenser tube and an arc length less than half that of the condenser tube. The reaming cavity has a diameter greater than that of the clamping cavity and is located at one end of the fixture adjacent to the Y-axis worktable. The cutting tool is vertically positioned above the end of the reaming cavity. The top of the cutting tool is connected to the push rod of a pad, and the pad is fixed on the cutting tool cylinder.

[0006] The jacket is elastic, and its outer wall is fixed to the push rod of the clamp cylinder by a connecting seat.

[0007] The clamp cylinder is fixed to the support platform by pad blocks, so that its push rod is positioned above the X-axis worktable.

[0008] The outer wall of the jacket is also machined with a positioning groove, which is located at the junction of the clamping cavity and the expansion cavity.

[0009] The cutting tool includes a clamping block and a cutting blade. The clamping block is fixed on the cutting blade. Several connecting holes on the top of the cutting blade are connected to the push rod of the cutting tool cylinder. The lower ends of the clamping block and the cutting blade are respectively machined with extrusion grooves and cutting edges. The extrusion grooves are square and their width is smaller than the diameter of the outer wall of the jacket. The cutting edges are semicircles with a diameter of 9.

[0010] The hole-expanding device includes an expanding cone, which is vertically fixed to one side of the bridging block. The other end of the bridging block is fixed to the Y-axis worktable. The Y-axis worktable is mounted on a Y-axis slide rail parallel to the clamping sleeve. The Y-axis slide rail is fixed to the X-axis worktable. The side of the Y-axis worktable facing away from the fixture is connected to a Y-axis drive cylinder fixed to the X-axis worktable.

[0011] The X-axis worktable is mounted on an X-axis slide rail perpendicular to the fixture. The X-axis slide rail is fixed on a support platform, and an X-axis drive cylinder is also fixed on the support platform. The push rod of the X-axis drive cylinder is connected to the side of the X-axis worktable perpendicular to the X-axis slide rail.

[0012] The beneficial effect of this utility model is that the punching action can reduce the burrs on the condenser tube compared with the traditional cutting action.

[0013] The tool design divides the punching process into two steps. The beveled surface of the tool first contacts the extrusion fixture and then punches the condenser tube. Compared with a single punching step, this reduces the deformation of the condenser tube.

[0014] When the fixture is squeezed or expanded, it will undergo a certain elastic deformation. Due to this characteristic, combined with the installation of the molding clip, the fixture can simultaneously achieve the purpose of clamping and expanding the condenser tube during punching and hole expansion, thus reducing time costs.

Detailed Implementation

[0020] The technical solution of this utility model is further described below, but the scope of protection is not limited to what is described.

[0021] A condenser tube cutting and reaming platform includes an X-axis worktable 2, a Y-axis worktable 3, a fixture 4, and a cutting tool 5. The Y-axis worktable 3 and the fixture 4 are respectively mounted above the X-axis worktable 2. A reaming device is installed on the Y-axis worktable 3. The fixture 4 includes two clamping sleeves 42, which are semi-cylinders. The two clamping sleeves 42 are opposite each other and respectively mounted on the push rods of two fixture cylinders 13. The axial ends of the clamping sleeves 42 are respectively machined with a clamping cavity 43 and a reaming cavity 45. The clamping cavity 43 is an arc groove with a diameter equal to that of the condenser tube 8 and an arc length less than half that of the condenser tube 8, so that after the clamping sleeves are clamped, the two clamping sleeves will not come into contact with each other and generate mutual thrust, thus affecting the clamping effect. The diameter of the expanding cavity 45 is larger than the diameter of the clamping cavity 43 and is located at one end of the fixture 4 adjacent to the Y-axis worktable 3. The cutting tool 5 is vertically positioned above the end of the expanding cavity 45. The top of the cutting tool 5 is connected to the push rod of the pad 12, and the pad 12 is fixed on the cutting tool cylinder 6.

[0022] Further, such as Figure 2 As shown, the sleeve 42 is elastic, so that the clamp and the condenser tube are in soft contact and the condenser tube will not be deformed due to compression. The outer wall of the sleeve 42 is fixed to the push rod of the clamp cylinder 13 through the connecting seat 41, and the condenser tube is clamped by the connecting seat as a force-applying component.

[0023] Further, such as Figure 1 As shown, the clamp cylinder 13 is supported and fixed on the support platform 1 by the pad block 12, so that its push rod is positioned above the X-axis worktable 2.

[0024] Furthermore, a positioning groove 44 is machined on the outer wall of the jacket 42, and the positioning groove 44 is located at the junction of the clamping cavity 43 and the expansion cavity 45. The positioning groove facilitates the positioning of the jacket 42 during the connection process with the connecting seat.

[0025] Further, such as Figure 4As shown, the tool 5 includes a clamping block 51 and a cutter 52. The clamping block 51 is fixed on the cutter 52. Several connecting holes 53 on the top of the cutter 52 are connected to the push rod of the tool cylinder 6. The lower ends of the clamping block 51 and the cutter 52 are respectively machined with extrusion grooves 55 and cutting edges 54. Since the expansion cavity 45 needs to leave room for the expansion after the expansion, the diameter of the expansion cavity is larger than that of the condenser tube before the expansion. In order to prevent the condenser tube from loosening during the punching process, the extrusion groove 55 is square and its width is smaller than the outer wall diameter of the jacket 42, so that the extrusion groove 55 can extrude the part of the jacket 42 that has the expansion cavity. It first contacts the jacket 42 and extrudes the jacket to deform and make complete contact with the condenser tube. Then, it is positioned by the cutting edge 52 and contacts the condenser tube. Finally, the cutter in the cutting edge punches the condenser tube.

[0026] Further, such as Figure 1 As shown, the hole-reaming device includes a hole-reaming cone 32, which is vertically fixed to one side of the bridging block 31. The other end of the bridging block 31 is fixed to the Y-axis worktable 3. The Y-axis worktable 3 is mounted on the Y-axis slide rail 21 parallel to the clamp 42. The Y-axis slide rail 21 is fixed to the X-axis worktable 2. The side of the Y-axis worktable 3 facing away from the fixture 4 is connected to the Y-axis drive cylinder 22 fixed to the X-axis worktable 2.

[0027] Furthermore, the X-axis worktable 2 is mounted on the X-axis slide rail 14 perpendicular to the fixture 4. The X-axis slide rail 14 is fixed on the support platform 1. An X-axis drive cylinder 11 is also fixed on the support platform 1. The push rod of the X-axis drive cylinder 11 is connected to the side of the X-axis worktable 2 perpendicular to the X-axis slide rail 14.

[0028] The processing of this application consists of two steps:

[0029] I. Punching and cutting Figure 1 As shown, after the condenser tube 8 completes the bending action, it is placed in the middle of the clamp 4. The two clamp cylinders push the clamp to hold the condenser tube 8 tightly, and then the cutter 5 punches the condenser tube under the push of the cutter cylinder.

[0030] Second, hole enlargement: First, the X-axis drive cylinder drives the X-axis worktable 2 to align the hole enlargement cone 32 with the condenser tube. Then, under the drive of the Y-axis drive cylinder, the Y-axis worktable 3 drives the hole enlargement cone to extend into the condenser tube to enlarge the hole.
