DETAILED DESCRIPTION
[0021] The utility model is further described below in conjunction with the accompanying drawings.
[0022] The utility model provides a feeding device for air conditioner copper pipe joints with a printing function, such as Figure 1 As shown, it includes a conveying assembly 1 for conveying the hexagonal copper rod 99 to the left, a clamping and positioning assembly 2 for clamping the hexagonal copper rod 99, and a cutting assembly 3 for cutting the hexagonal copper rod 99. Figure 1 As shown, the blanking device of the utility model also includes a printing component 4 for printing characters on the side of a section of hexagonal copper rod 99 to be cut out, such as Figure 7 As shown, the printing assembly 4 includes a rear stamping seat 41 and a front stamping seat 42 which are both slidably arranged forward and backward. Specifically, the printing assembly 4 includes a dovetail groove seat 45. The lower end of the rear stamping seat 41 is formed with a dovetail structure. The lower end of the rear stamping seat 41 is adapted to be connected with the dovetail groove of the corresponding dovetail groove seat 45. Similarly, the front stamping seat 42 is slidably connected to the corresponding dovetail groove seat 45. Figure 7As shown in FIG. 7 , the front end of the rear stamping seat 41 and the rear end of the front stamping seat 42 are respectively provided with a printing mold 40, and the rear stamping seat 41 and the front stamping seat 42 are arranged opposite to each other. In other words, the printing mold 40 located at the front end of the rear stamping seat 41 and the printing mold 40 located at the rear end of the front stamping seat 42 are arranged opposite to each other; as shown in FIG. 7 , the printing assembly 4 includes a rear hydraulic cylinder 43 and a front hydraulic cylinder 44, and the rear hydraulic cylinder 43 drives the rear stamping seat 41 to move forward and backward, and the front hydraulic cylinder 44 drives the front stamping seat 42 to move forward and backward. Specifically, the piston rod of the rear hydraulic cylinder 43 is screwed to the rear end of the rear stamping seat 41 and fixed by a nut. Figure 4 As shown, the cutting assembly 3 includes a saw disc 31, as shown in FIG. Figure 1 As shown, the rear stamping seat 41 and the front stamping seat 42 are arranged on the left side of the saw disc 31, and the clamping and positioning assembly 2 is arranged on the right side of the saw disc 31. Figure 2 and Figure 3 As shown, the conveying assembly 1 includes a driving wheel 11, a driving wheel motor 12, a pressure wheel 13, a slider 14, a pressure wheel lifting cylinder 15 and a support wheel 16. The driving wheel 11 and the support wheel 16 are arranged at the same height. The driving wheel 11 and the support wheel 16 are both arranged to rotate with a fixed axis. The pressure wheel 13 is rotatably connected to the slider 14, and the slider 14 is arranged to slide linearly up and down. Figure 3 As shown, the center of the pressing wheel 13 is located between the center of the driving wheel 11 and the center of the supporting wheel 16 (in the left-right direction), and the piston rod of the pressing wheel lifting cylinder 15 is connected to the slider 14, so that the pressing wheel lifting cylinder 15 can drive the pressing wheel 13 to move up and down, and the driving wheel motor 12 drives the driving wheel 11 to rotate through the transmission shaft; Figure 2 and Figure 3 As shown, the driving wheel 11 and the supporting wheel 16 support the lower part of the hexagonal copper rod 99, and the pressing wheel 13 is pressed on the upper part of the hexagonal copper rod 99 by the pressing wheel lifting cylinder 15. Therefore, when the driving wheel motor 12 drives the driving wheel 11 to rotate, the driving wheel 11 drives the hexagonal copper rod 99 to move to the left through friction; when the pressing wheel lifting cylinder 15 lifts the pressing wheel 13, the hexagonal copper rod 99 can be quickly placed on the driving wheel 11 and the supporting wheel 16. Figure 4 As shown, the cutting component 3 also includes a saw disk swing arm 32, and the saw disk 31 is rotatably connected to the front end of the saw disk swing arm 32. When the saw disk swing arm 32 swings downward, the edge of the saw disk 31 can cut the hexagonal copper rod 99. During this period, the saw disk 31 is driven to rotate by the saw disk motor of the cutting component 3.
[0023] The following briefly describes the working principle of the unloading device of the utility model: the conveying component 1 conveys the hexagonal copper rod 99 to the left. When the relative position of the left end face of the hexagonal copper rod 99 and the saw disk 31 is appropriate, the conveying component 1 stops working, and then the clamping and positioning component 2 clamps and fixes the hexagonal copper rod 99, and then the rear hydraulic cylinder 43 drives the rear stamping seat 41 to move forward, and synchronously, the front hydraulic cylinder 44 drives the front stamping seat 42 to move backward, that is, the two printing molds 40 located at the front stamping seat 42 and the rear stamping seat 41 respectively move toward each other synchronously, so the convex mold on the printing mold 40 arranged on the front stamping seat 42 is pressed on the front side surface of the hexagonal copper rod 99, and the convex mold on the printing mold 40 arranged on the rear stamping seat 41 is pressed on the rear side surface of the hexagonal copper rod 99, so that the front of the hexagonal copper rod 99 Concave characters are embossed on the rear side surfaces respectively, among which the concave characters on the front and rear side surfaces of the hexagonal copper rod 99 are staggered left and right. For example, the concave characters on the front side surface of the hexagonal copper rod 99 are arranged on the left to represent the thread specifications to be processed on the left end of the hexagonal copper rod 99, and the concave characters on the rear side surface of the hexagonal copper rod 99 are arranged on the right to represent the thread specifications to be processed on the right end of the hexagonal copper rod 99. After the printing is completed, the front hydraulic cylinder 44 drives the front stamping seat 42 to move forward and reset, and the rear hydraulic cylinder 43 drives the rear stamping seat 41 to move backward and reset synchronously; then the saw disk swing arm 32 is swung downward, so that the saw disk 31 moves down to cut off the hexagonal copper rod 99 to cut out a section of the hexagonal copper rod 99 (air conditioner copper pipe joint blank) of suitable length, the clamping and positioning component 2 releases the hexagonal copper rod 99, and the conveying component 1 resumes conveying the hexagonal copper rod 99. During the process, since the left end of the hexagonal copper rod 99 can be clamped and fixed by the clamping and positioning assembly 2 before the stamping process, the hexagonal copper rod 99 is prevented from shifting during the printing process of the printing mold 40, which is conducive to accurate printing position and clear concave characters on the side of the hexagonal copper rod 99. Since the front and rear sides of the hexagonal copper rod 99 can be pushed by the corresponding printing mold 40 at the same time, the hexagonal copper rod 99 is balanced in force, thereby preventing the hexagonal copper rod 99 from being pushed and deformed. When the air-conditioning copper pipe joint blanks with printed thread specifications are transferred to the lathe station for processing, the workers can quickly check the thread specifications to perform turning accordingly, which plays a role of re-inspection and avoids mistakes. For example, there may be several boxes of air-conditioning copper pipe joint blanks in the workshop, and each box of air-conditioning copper pipe joint blanks corresponds to different drawings. Therefore, the lathe workers can review the thread specifications on the air-conditioning copper pipe joint blanks with the drawings to avoid turning the wrong threads of the entire box of air-conditioning copper pipe joint blanks. Relatively speaking, the accuracy of the printed content can be improved, that is, to avoid the inconsistency between the printed content and the actual thread specifications, and to avoid the need for manual stamping, so work efficiency can be greatly improved.
[0024] Furthermore, if Figure 4 As shown, the clamping and positioning assembly 2 includes a clamping arm 21 and a support seat 23. The clamping arm 21 is swingably arranged, and the support seat 23 is fixedly arranged. The support seat 23 can be fixed on the working table of the blanking device by screws, such as Figure 6As shown, the support seat 23 is formed with a circumferential positioning angle opening 2301 for fitting the lower end corner of the hexagonal copper rod 99, so the circumferential positioning angle opening 2301 is a 120-degree V-shaped groove, as shown in FIG. Figure 5 As shown, a movable corner opening 2101 for fitting the upper corner of the hexagonal copper rod 99 is formed on the lower side of one end of the clamp arm 21, so the movable corner opening 2101 is a 120-degree inverted V-shaped notch, as shown in FIG. Figure 4 As shown, the clamping and positioning assembly 2 includes a clamp arm swing cylinder 22, which drives the clamp arm 21 to swing up and down. Specifically, the front end of the clamp arm 21 is hinged to the workbench, and the movable corner 2101 is formed at the rear end of the clamp arm 21. The swing axis of the clamp arm 21 is extended in the left and right directions. The upper end of the piston rod of the clamp arm swing cylinder 22 slides and hinges to the approximate middle position of the clamp arm 21 in the front and rear directions. The cylinder body of the clamp arm swing cylinder 22 is fixed to the workbench, so that when the piston rod of the clamp arm swing cylinder 22 contracts, it can drive the clamp arm 21 to swing downward, so that the movable corner 2101 is buckled downward on the upper end corner of the hexagonal copper rod 99, as shown in FIG. Figure 4 As shown, the hexagonal copper rod 99 is clamped by the movable angle opening 2101 in cooperation with the circumferential positioning angle opening 2301, so as to prevent the hexagonal copper rod 99 from rotating circumferentially around the central axis of the hexagonal copper rod 99 and also prevent the hexagonal copper rod 99 from shifting along the central axis of the hexagonal copper rod 99, which is beneficial to clear printing and a straight cut of the hexagonal copper rod 99.
[0025] Furthermore, if Figure 8 As shown, the rear stamping seat 41 and the front stamping seat 42 are respectively formed with dovetail mounting grooves 402 ( Figure 8 The front stamping seat 42 is shown as an example. Figure 7 As shown, the printing molds 40 are respectively adapted to be installed in the corresponding dovetail installation grooves 402. In other words, a convex mold is formed on one side of the printing mold 40, and a dovetail structure is formed on the other side of the printing mold 40. Specifically, the printing mold 40 is inserted into the dovetail installation groove 402 along the left and right directions. The printing mold 40 can be installed and removed by a simple sliding action, which is conducive to the rapid installation, removal or replacement of the printing mold 40. Figure 8 As shown, the front stamping seat 42 and the rear stamping seat 41 are respectively formed with screw holes 4021, and the screw holes 4021 are connected to the dovetail mounting groove 402, as shown in FIG. Figure 7 As shown, set screws 401 are respectively installed in the screw holes 4021, and the lower ends of the set screws 401 respectively press the printing mold 40 correspondingly, so that the printing mold 40 is reliably fixed.
[0026] Furthermore, if Figure 1 As shown, the feeding device of the present utility model also includes a cleaning brush component 5, such as Figure 1 and Fig. 9As shown, the cleaning brush assembly 5 includes a rear wire brush wheel 51 for scraping the rear side of the hexagonal copper rod 99 and a front wire brush wheel 52 for scraping the front side of the hexagonal copper rod 99. The rotation axis of the rear wire brush wheel 51 and the rotation axis of the front wire brush wheel 52 are both vertically arranged. Figure 1 As shown, the rear wire brush wheel 51 and the front wire brush wheel 52 are arranged on the right side of the clamping and positioning component 2, so when the rear wire brush wheel 51 and the front wire brush wheel 52 rotate, the bristles of the rear wire brush wheel 51 scrape the rear side of the hexagonal copper rod 99, and the bristles of the front wire brush wheel 52 scrape the front side of the hexagonal copper rod 99, which can clean up the debris adhering to the front and rear sides of the hexagonal copper rod 99, and then the hexagonal copper rod 99 is transported to the printing component 4 station, which can prevent the debris from blocking the convex mold of the printing mold 40, thereby avoiding the situation where the printing is partially unclear, and also preventing the convex mold of the printing mold 40 from hitting the sand particles and causing poor durability. Figure 1 As shown, the rear wire brush wheel 51 and the front wire brush wheel 52 can be arranged on the left side of the conveying component 1.
[0027] Furthermore, if Fig. 9 As shown, the brush cleaning assembly 5 includes a rear gear 511 and a front gear 521. The rear gear 511 and the rear wire brush wheel 51 are coaxially fixedly arranged relatively. Specifically, the rear gear 511 and the rear wire brush wheel 51 are respectively fixed to the same rear shaft by flat keys and screws, and the front gear 521 and the front wire brush wheel 52 are coaxially fixedly arranged relatively. Similarly, the front gear 521 and the front wire brush wheel 52 are respectively fixed to the same front shaft by flat keys and screws, and the rear gear 511 is meshed and connected with the front gear 521. The brush cleaning assembly 5 includes a brush wheel motor 53. The brush wheel motor 53 drives the rear gear 511 to rotate. The output shaft of the brush wheel motor 53 can be specifically connected to the lower end of the above-mentioned rear shaft. Therefore, when the brush wheel motor 53 is running, it drives the rear gear 511 to rotate, and the rear gear 511 drives the front gear 521 to rotate, so that the front wire brush wheel 52 and the rear wire brush wheel 51 can rotate together. Figure 1 As shown, preferably, the rear wire brush wheel 51 rotates counterclockwise, so that the front wire brush wheel 52 rotates clockwise, so that the rear wire brush wheel 51 and the front wire brush wheel 52 both scrape the hexagonal copper rod 99 against the conveying direction of the hexagonal copper rod 99, thereby preventing the debris from being swept onto the left end of the hexagonal copper rod 99. The structural cost of the front wire brush wheel 52 and the rear wire brush wheel 51 being driven to rotate synchronously by a brush wheel motor 53 is relatively low.
