Description

Technical Field

[0001] This invention relates to the field of forging ball processing equipment, and particularly to a forging ball production device. Background Technology

[0002] Forged balls are steel balls produced through a forging process, and their foreign name is forged steel balls. They are manufactured according to the national standard YB / T 091-2005. The production process covers five core steps: raw material preparation, heating, forging, heat treatment, and testing. Free forging, on the other hand, is a forging method that uses impact force or static pressure to freely deform metal between upper and lower anvils without the need for molds.

[0003] Existing free forging methods often involve manually adjusting the forging angle, requiring skilled workers to constantly use pliers to manipulate the semi-finished product to be forged, which is generally a cylindrical forging material. In this process, the forger can only rely on visual observation, without the assistance of instruments or safety measures, resulting in a very low level of automation. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art and achieve the above-mentioned functions, the present invention provides a forging ball production device.

[0005] This invention is achieved through the following technical solution: A forging ball production apparatus includes an electric rotating platform located outside the anvil, wherein three lifting mechanisms are uniformly fixed on the rotating disk surface of the electric rotating platform. The lifting mechanism includes a base plate, which is fixedly connected to the upper lifting plate via a lifting electric cylinder. The lifting plate has a bearing plate rotatably connected to the side facing the forging ball. A shock-absorbing plate is fixed to the inner side of the bearing plate, and a contact plate is fixed to the shock-absorbing plate. Each contact plate is provided with a spherical arc-shaped support opening adapted to the outer side of the forging ball. The bearing plate is provided with a front shaft and the lifting plate is provided with a rear shaft. A wide belt is fixed on the rear shaft. The other end of the wide belt is wound into a circle and rotates in contact with the front shaft. The rear shaft is connected to the output shaft of the motor through a coupling. The motor drives the winding and unwinding of the wide belt, thereby driving the rotation of the contact plate.

[0006] Furthermore, a circular rubber pad is installed between the electric rotary platform and the anvil, the circular rubber pad does not contact the electric rotary platform, shock absorbers are installed at the four corners of the bottom of the electric rotary platform, and a material rail is provided on the outside of the electric rotary platform.

[0007] Furthermore, a telescopic cylinder is provided on the base plate, and the other end of the telescopic cylinder is fixed to the bottom of the lifting plate.

[0008] Furthermore, an L-shaped positioning sheet metal is installed on the base plate, and infrared temperature sensors a are fixed on both sides of the positioning sheet metal. A fixing plate is fixed on the lifting plate, and an arc plate is welded to the inner side of the fixing plate. Three infrared temperature sensors b are fixed on the arc plate, and the infrared temperature sensors b are all facing the vertical rotation axis of the rotating disk.

[0009] Furthermore, a groove is provided on one side of the damping plate, and several rubber dampers are installed in the groove. The other end of the rubber damper is inserted into a circular slot on the end face of the bearing plate.

[0010] Furthermore, bearing seats a are provided at both ends of the bearing plate, and the front shaft is rotatably connected to the bearing seats a at both ends; The lifting plate is provided with two bearing seats b, which are rotatably connected to the rear shaft.

[0011] The beneficial effects of this invention are: This invention can replace manual adjustment of the forging ball during the free forging process, achieving the same result as transforming the forging material into a forging ball. It reduces safety hazards caused by high temperature and vibration, improves forging efficiency, and reduces production costs. Attached Figure Description

[0014] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0015] Therefore, the following detailed description of the embodiments of the invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the invention without inventive effort are within the scope of protection of the invention.

[0016] refer to Figures 1 to 5 The present invention includes an electric rotating platform 2 located outside the anvil 1. Three lifting mechanisms 3 are evenly fixed on the rotating disk 201 of the electric rotating platform 2, that is, the included angle between each pair is 120 degrees, which facilitates the all-round detection of the state of the forging ball. The lifting mechanism 3 includes a base plate 301 fixed to the rotating disk 201 by bolts. The base plate 301 is fixedly connected to the upper lifting plate 302 by a lifting cylinder 501. The lifting plate 302 is provided with a bearing plate 303 rotatably connected to the side facing the forging ball. A shock-absorbing plate 304 is fixed on the inner side of the bearing plate 303, which mainly plays a shock-absorbing role. A contact plate 305 is fixed on the shock-absorbing plate 304. Each contact plate 305 is provided with a spherical arc-shaped support 3051 adapted to the outer side of the forging ball to limit the cylindrical material in the early stage and play a role in locking and supporting the bottom when the forging ball is basically formed. The bearing plate 303 is provided with a front shaft 901, and the lifting plate 302 is provided with a rear shaft 904. A wide belt 905 is fixed on the rear shaft 904, i.e., fixed connection. The other end of the wide belt 905 is wound into a circle and rotates in contact with the front shaft 901, i.e., surface contact and rotational connection. The rear shaft 904 is connected to the output shaft of the motor 902 through a coupling. The motor 902 drives the wide belt 905 to wind and unwind, thereby driving the rotation of the contact plate 305.

[0017] A circular rubber pad 101 is installed between the electric rotating platform 2 and the anvil 1. The circular rubber pad 101 does not contact the electric rotating platform 2. Shock absorbers 10 are installed at the four corners of the bottom of the electric rotating platform 2. A material rail 11 is provided on the outside of the electric rotating platform 2, which can be used for unloading. When unloading, conventional robotic arms can be used, or the picking mechanisms on both sides can be changed to a certain shape using the corresponding logic program.

[0018] The base plate 301 is provided with a telescopic cylinder 5. The other end of the telescopic cylinder 5 is fixed to the bottom of the lifting plate 302 to play a limiting and guiding role. Of course, it can also be replaced with a limiting guide sleeve and a guide shaft, that is, it is necessary to prevent vertical displacement.

[0019] An L-shaped positioning sheet metal 4 is installed on the base plate 301, and infrared temperature sensors a401 are fixed on both sides of the positioning sheet metal 4; a fixing plate 6 is fixed on the lifting plate 302, and an arc plate 601 is welded to the inner side of the fixing plate 6. Three infrared temperature sensors b7 are fixed on the arc plate 601. The infrared temperature sensors b7 are all facing the vertical rotation axis of the rotating disk 201, and can detect whether the temperature of the forging ball meets the required standard. Of course, a composite sensor (dual detection of distance and temperature) can also be used, and multiple different sensors on the top and bottom can monitor from multiple directions.

[0020] The damping plate 304 has a groove on one side, and several rubber dampers 8 are installed in the groove. The other end of the rubber damper 8 is inserted into the circular slot on the end face of the bearing plate 303 to absorb the vibration transmitted between the contact plate 305 and the lifting plate 302.

[0021] The bearing plate 303 is provided with bearing seats a9 at both ends, and the front shaft 901 is rotatably connected to the bearing seats a9 at both ends. The lifting plate 302 is provided with two bearing seats b903, which are rotatably connected to the rear shaft 904.

[0022] When the forging ball is fully attached to the anvil 1, the support opening 3051 is attached to the forging ball and located at the lower quarter of the middle of the forging ball, which facilitates limiting, clamping, supporting and lifting the forging ball.

[0023] The electrical components in this invention are all connected and controlled by conventional PLCs, switching power supplies, etc., which is existing technology and will not be described in detail here.

[0024] The working principle of this invention is as follows: (1) The forging material (usually cylindrical) slides from the conventional material rail (or robot) onto the concave anvil 1. According to the diameter of the cylinder, the support openings 3051 on the three lifting mechanisms 3 limit the forging material to keep it upright. (2) The air hammer keeps hitting down. During the hitting process, the diameter of the forging gradually increases and the forging gradually becomes elliptical. The contact plate 305 is squeezed and gradually expands (in order to avoid the motor being burned out, the contact plate 305 is simply limited at this time, that is, a gap is maintained with the forging ball). The contact plate 305 keeps moving diagonally downward. (3) After the set number of hammer blows is reached, the motor 902 drives the contact plate 305 to lift up to a certain angle (the specific angle needs to be adjusted by the tester according to the on-site situation). At this time, since the support opening 3051 is located at the lower quarter of the middle of the forging ball, the forging ball is lifted up and slides onto the contact plate 305. Then, after one of the contact plates 305 falls down, the two contact plates 305 fall down at the same time to change the effect of the surface of the forging ball being hammered. In this way, the three sets of lifting mechanisms 3 change in sequence, so that the forging ball is hammered in all directions.

[0025] (4) Of course, after the three lifting mechanisms 3 lift the forging ball, the electric rotating platform 2 rotates, puts down the forging ball, and then the electric rotating platform 2 resets and performs the operation of process (2) again; thereby achieving the purpose of adjusting the horizontal angle of the forging ball.

[0026] (5) During material discharge, the lifting mechanism 3 opposite to the material rail 11 is raised to a certain degree, and the remaining two are also raised together but lower than the first height. During this process, the lifting mechanism 3 opposite to the material rail 11 increases the lifting amplitude again, so that the forging ball is pushed to the height along the material rail 11. The entire operation relies on the parameter setting of the debugging engineer and there is no specific value (of course, a loading and unloading robot can also be used to place it on the material rail 11. This invention provides a solution for this mechanical structure).

[0027] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solutions of the present invention, as long as they do not depart from the spirit and scope of the technical solutions of the present invention, should be covered within the scope of the claims of the present invention.
