Description

Technical Field

[0001] This utility model relates to the field of pipe fitting processing equipment technology, and in particular to a ball recovery device. Background Technology

[0002] In pipe fitting manufacturing, a common example is the tee pipe. Its production typically involves drilling holes in the sidewall of the water pipe and then shaping the pipe end at the drilled hole. For everyday water pipe fittings, tee pipes are formed by drawing using a ball-drawing process, eliminating the need for manual welding. However, this method requires reloading the ball after each drawing process. Therefore, current methods generally involve having multiple balls ready at once, collecting them all at once after a certain number of processing cycles, or immediately picking them up and reloading them after each drawing process. This method requires a significant amount of manual labor and has poor processing continuity. Utility Model Content

The mold fixing seat is provided with a ball dropping channel for docking with the drawing channel of the drawing die, and the top of the mold fixing seat is provided with a ball guide groove for guiding the drawing ball into the drawing die.

[0005] The circulating transfer mechanism includes a ball receiving plate and a lifting drive rod for driving the ball receiving plate to rise and fall. The ball being pulled in the pulling channel falls into the ball receiving plate through the ball falling channel.

[0006] One side wall of the ball receiving plate is attached to the mold fixing seat, and the other side is hinged to the lifting drive rod, so that after the ball receiving plate is raised to a preset height, the ball receiving plate loses the lateral support of the mold fixing seat and tilts towards the ball guide groove.

[0007] As an improvement to the above solution, the bottom of the ball receiving plate is provided with a hinge groove for inserting the lifting drive rod and providing hinge space. One end of the lifting drive rod is hinged in the hinge groove to limit the swing amplitude of the ball receiving plate relative to the lifting drive rod.

[0008] As an improvement to the above solution, the distance between the top surface of the lifting drive rod and the bottom surface of the hinge groove is A, and the maximum distance from the hinge point of the lifting drive rod and the ball receiving plate to the top surface of the lifting drive rod is B, where B is greater than A.

[0009] As an improvement to the above solution, the ball receiving plate is provided with a ball receiving groove to prevent the pulled ball from rolling out of the ball receiving plate, and an inclined surface is provided on the inner side wall of the ball receiving groove near the mold fixing seat to guide the pulled ball into or out of the ball receiving groove.

[0010] As an improvement to the above solution, the ball receiving groove is provided with a movable interceptor for blocking the pulling of the ball.

[0011] As an improvement to the above solution, the active interceptor includes a counterweight body and a buffer layer. The counterweight body is provided with a buffer surface for receiving the impact of the pull ball, and the buffer layer is provided on the buffer surface.

[0013] As an improvement to the above solution, the movable interceptor is in the shape of a roller, and the inner sidewall of the ball receiving groove is provided with a stroke hole for limiting the movement of the movable interceptor within the ball receiving groove. Both ends of the movable interceptor are provided with rotating shafts for insertion and installation within the stroke holes.

[0014] As an improvement to the above solution, a transition arc surface is provided between one side wall of the ball receiving plate and the bottom surface to guide the ball receiving plate from an inclined state to a horizontal state during the descent.

[0015] As an improvement to the above solution, a spring is provided between the ball receiving plate and the lifting drive rod to maintain the ball receiving plate in a horizontal state, and the two ends of the spring are respectively connected to the lifting drive rod and the ball receiving plate.

[0016] Implementing this utility model has the following beneficial effects:

[0017] This utility model discloses a drawing ball recovery device, including a mold fixing seat for installing a drawing die and a circulation transfer mechanism disposed on one side of the mold fixing seat. The mold fixing seat is provided with a ball dropping channel for connecting with the drawing channel of the drawing die. The top of the mold fixing seat is provided with a ball guide groove for guiding the drawing ball into the drawing die. Therefore, the drawing ball loading of the drawing die can be completed simply by sending the drawing ball into the ball guide groove.

[0018] Moreover, the circulating transfer mechanism includes a ball receiving plate and a lifting drive rod for driving the ball receiving plate to rise and fall. The ball being pulled in the pulling channel falls into the ball receiving plate through the ball dropping channel to directly recover the ball, eliminating the trouble of manual collection and solving the problem of storing multiple balls.

[0019] One side wall of the receiving plate is attached to the mold fixing seat, and the other side is hinged to the lifting drive rod. After the receiving plate rises to a preset height, it loses the lateral support of the mold fixing seat and tilts towards the ball guide groove. This allows the ball to leave the hitting plate with a certain initial velocity, ensuring that the ball has enough kinetic energy to pass through the ball guide groove and fall into the ball drop channel.

[0024] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0025] See Figure 1 , 2 In addition to the above, this utility model provides a ball recovery device, including a mold fixing seat 1 for installing a drawing die and a circulation transfer mechanism provided on one side of the mold fixing seat 1. The mold fixing seat 1 is provided with a ball dropping channel 1a for connecting to the drawing channel of the drawing die. The top of the mold fixing seat 1 is provided with a ball guide groove 2 for guiding the drawing ball into the drawing die.

[0026] The circulating transfer mechanism includes a ball receiving plate 3 and a lifting drive rod 4 for driving the ball receiving plate 3 to rise and fall. The ball being pulled in the pulling channel falls into the ball receiving plate 3 through the ball falling channel 1a.

[0027] One side wall of the ball receiving plate 3 is fitted against the mold fixing seat 1, and the other side is hinged to the lifting drive rod 4, so that after the ball receiving plate 3 rises to a preset height, it loses the lateral support of the mold fixing seat 1 and tilts towards the ball guide groove 2. The lifting drive rod 4 is preferably driven by a pneumatic telescopic rod mechanism, an electric push rod, or a lead screw transmission mechanism, which are existing technologies.

[0028] Specifically, the bottom of the ball receiving plate 3 is provided with a hinge groove 31 for the insertion of the lifting drive rod 4 and for providing hinge space. One end of the lifting drive rod 4 is hinged within the hinge groove 31 to limit the swing amplitude of the ball receiving plate 3 relative to the lifting drive rod 4. More specifically, the distance between the top surface of the lifting drive rod 4 and the bottom surface of the hinge groove 31 is A, and the maximum distance from the hinge point of the lifting drive rod 4 and the ball receiving plate 3 to the top surface of the lifting drive rod 4 is B, where B is greater than A. With this configuration, when the ball receiving plate 3 rotates to a certain angle, the lifting drive rod 4 will press against the bottom surface of the hinge groove 31, thereby limiting further tilting of the ball receiving plate 3.

[0029] To ensure that the ball receiving tray 3 can smoothly return to a horizontal state after the ball is delivered, and to allow one side wall of the ball receiving tray 3 to fit against the mold fixing base 1, a transition arc surface 32 is provided between one side wall of the ball receiving tray 3 and its bottom surface. This transition arc surface 32 guides the ball receiving tray 3 from an inclined state to a horizontal state during descent, preventing jamming. Accordingly, the inclination range of the ball receiving tray 3 can be limited to ensure that the transition arc surface 32 makes guiding contact with the mold fixing base 1.

[0030] The ball receiving tray 3 is provided with a ball receiving groove 33 to prevent the pulled ball from rolling out of the ball receiving tray 3. An inclined surface 11 is provided on the inner side wall of the ball receiving groove 33 near the mold fixing seat 1 to guide the pulled ball into or out of the ball receiving groove 33. The ball receiving groove 33 can prevent the pulled ball from accidentally rolling back into the ball dropping channel 1a. The inclined surface 11 can facilitate the pulled ball to leave the ball receiving groove 33 along the inclined surface 11 when the ball receiving tray 3 is in an inclined state.

[0031] Furthermore, since the pulling force on the ball during the pulling process is extremely large, there is a certain probability that the pulled ball will have a relatively high moving speed after being squeezed out of the ball dropping channel. Therefore, in order to prevent the pulled ball from flying away from the receiving plate 3 due to excessive speed, the receiving groove 33 is provided with a movable interceptor 5 for blocking the pulled ball.

[0032] The movable interceptor 5 includes a counterweight body and a buffer layer. The counterweight body has a buffer surface for receiving the impact of the pulled ball, and the buffer layer is disposed on the buffer surface. Preferably, the weight of the movable interceptor is 1 / 2 to 3 / 4 of the weight of the pulled ball to prevent the pulled ball from rebounding. Preferably, the buffer layer is made of rubber. Preferably, the counterweight body is triangular prism-shaped, such as... Figure 2 and Figure 3 .

[0033] See Figure 4In addition to the movable interceptor 5, this utility model also discloses another embodiment, wherein the movable interceptor 5 is in the shape of a roller, and the inner sidewall of the ball receiving groove 33 is provided with a stroke hole 331 for limiting the movement of the movable interceptor within the ball receiving groove 33. Both ends of the movable interceptor 5 are provided with a rotating shaft for insertion and installation within the stroke hole 331, so as to enhance the mobility of the movable interceptor.

[0034] Since the weight of the movable interceptor is 1 / 2 to 3 / 4 of the weight of the ball being pulled, the movable interceptor 5 will move backward after being hit by the ball being pulled, so that when the ball receiving plate 3 is tilted, the movable interceptor 5 will roll downward to help the ball being pulled into the ball guide groove 2.

[0035] A spring 6 is provided between the ball receiving plate 3 and the lifting drive rod 4 to maintain the ball receiving plate 3 in a horizontal state. The two ends of the spring 6 are connected to the lifting drive rod 4 and the ball receiving plate 3 respectively. Therefore, when the ball receiving plate 3 releases the pulled ball, the spring 6 can assist the ball receiving plate 3 to return to a horizontal state during the process of descending and resetting, thereby reducing the possibility of jamming.

[0036] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
