Description

Technical Field

[0001] The present invention relates to the technical field of machining, and particularly to an automatic annealing device for processing parts of plastic production equipment. Background Art

[0002] At present, most parts of plastic production equipment generally need to be annealed after processing. How to effectively achieve automatic annealing of plastic parts has become an urgent problem to be solved.

[0003] CN208497734U discloses an annealing furnace for stress relief after plastic part welding. Through a lifting device, the fire filter plate located below can be moved upward, and the flame density above the fire filter plate can be changed, so that the temperature of the furnace can be better controlled to ensure the annealing effect. However, the problem of how to achieve continuous annealing of parts has not been solved yet. The annealing treatment method still needs to stack a large number of parts of plastic production equipment and then push them into the heating furnace for heating, heat preservation and then cooling. The degree of automation is low, the heating efficiency is low, and the uneven heating of a large number of accessories affects the annealing effect. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: in order to overcome the deficiencies of the prior art, the present invention provides an automatic annealing device for processing parts of plastic production equipment with reasonable structural design, which can perform automatic annealing treatment on multiple batches of parts, realizes automatic heating and heat preservation, effectively improves the annealing heating efficiency, and improves the degree of automation of the annealing treatment.

[0005] The technical solution adopted by the present invention to solve its technical problems is: an automatic annealing device for processing parts of plastic production equipment, including a fixed seat, a rotating bracket, a group of workpiece clamping mechanisms and a heating mechanism; the rotating bracket is rotatably arranged on the fixed seat, and the workpiece clamping mechanisms are arranged in groups on the rotating bracket; each group of workpiece clamping mechanisms includes a number of workpiece clamping mechanisms evenly spaced, and each workpiece clamping mechanism includes an electric telescopic column, and the telescopic end of the electric telescopic column is sequentially connected with an automatic chuck, a clamping handle and a fitting placement rack; the heating mechanism includes a number of induction heating coils and a heating and heat preservation furnace, the induction heating coils are distributed corresponding to the arrangement mode of the workpiece clamping mechanisms in each group of workpiece clamping mechanisms, the fitting placement rack is correspondingly arranged above the induction heating coil, and the heating and heat preservation furnace is slidably arranged below the induction heating coil.

[0006] In the above solution, a group of workpiece clamping mechanisms can effectively clamp multiple groups of parts, and the heating mechanism is used for heating according to groups, so that group heat preservation annealing operations can be realized, and continuous heat preservation annealing can be carried out according to groups, realizing automatic heating and heat preservation, effectively improving the annealing heating efficiency, improving the degree of automation of the annealing treatment, ensuring heating uniformity, and being beneficial to ensuring the annealing treatment effect.

[0007] The rotation of the rotating bracket is realized by a indexing motor within the fixed seat. The fixed seat is internally fixed with an indexing motor, the output end of the indexing motor is drivingly connected with an indexing speed reducer, and the output end of the transmission speed reducer is rigidly connected with a flange shaft. The rotating bracket includes a cross beam and an indexing column fixed below the cross beam. The bottom of the indexing column is rotatably connected to the fixed seat, and the indexing column is rigidly connected with the flange shaft.

[0008] Each group of workpiece clamping mechanisms is fixedly arranged on the cross beam at equal intervals in a row, and several groups of workpiece clamping mechanisms are rotationally distributed on the cross beam with the rotation center of the indexing column as the center. By rotating the indexing column at a fixed angle, the accessories clamped by each group of workpiece clamping mechanisms can be heated, temperature-returned, and annealed in groups, realizing the return of multiple groups separately, and effectively improving the working efficiency.

[0009] In order to realize the installation and fixation of the induction heating coil, the heating mechanism further includes a gantry. The top of the induction heating coil is fixed below the gantry, and the heating end of the heating and heat preservation furnace corresponds to the bottom of the induction heating coil.

[0010] Furthermore, a group of parallel guide rails are symmetrically fixed below the gantry. Each group of guide rails is slidably connected with a sliding seat, and the heating and heat preservation furnace is fixed on the sliding seat.

[0011] Still further, the sliding between the sliding seat and the guide rail can be realized through the cooperative transmission of a gear and a rack. The rack is fixed on the guide rail, and a gear is rotatably connected to the sliding seat. The gear meshes with the rack. A sliding motor is also fixed on the sliding seat. The output end of the sliding motor is drivingly connected with a sliding speed reducer, and the output end of the sliding speed reducer is rigidly connected with a gear shaft, which is rigidly connected with the gear and drives the gear to rotate.

[0012] The beneficial effects of the present invention are as follows. An automatic annealing device for processing plastic production equipment spare parts provided by the present invention has a reasonable structural design. The rotatable workpiece clamping mechanism can drive parts batch by batch for automatic heating and heat preservation. At the same time, the heating of the heating mechanism is controllable, effectively improving the annealing heating efficiency, improving the automation degree of the annealing treatment, ensuring heating uniformity, and being beneficial to ensuring the annealing treatment effect.

[0018] Now, the present invention will be further described in detail with reference to the accompanying drawings. These drawings are all simplified schematic views, only illustrating the basic structure of the present invention in a schematic manner. Therefore, they only show the components related to the present invention, and directions and references (such as up, down, left, right, etc.) can only be used to assist in the description of the features in the drawings. Therefore, the following detailed implementation manners are not adopted in a restrictive sense, and the scope of the claimed subject matter is only defined by the appended claims and their equivalent forms.

[0019] As Figures 1 to 3 shown, an automatic annealing device for processing plastic production equipment spare parts is the optimal embodiment of the present invention, including a fixed seat, a rotating bracket, a set of workpiece clamping mechanisms and a heating mechanism. The rotating bracket is rotatably arranged on the fixed seat, and the workpiece clamping mechanisms are arranged in groups on the rotating bracket.

[0020] As Figure 2 shown, the rotation of the rotating bracket is driven by the indexing motor 3 in the fixed seat 1. The rotating bracket includes a cross beam and an indexing column fixed below the cross beam. The indexing column 2 is installed on the fixed seat 1 through bearing cooperation. The indexing motor 3 is rigidly installed on the bottom surface of the hollow inside of the fixed seat 1. The indexing speed reducer 4 is fixed to the housing of the indexing motor 3 through a speed reducer bracket. The flange shaft 5 is rigidly connected and installed between the power output end of the indexing speed reducer 4 and the indexing column 2. The cross beam 6 is rigidly installed on the indexing column 2. The electric telescopic columns 7 are symmetrically installed on the cross beam 6 in two groups on the left and right with multiple roots evenly distributed horizontally. By rotating the indexing column at a fixed angle, the accessories clamped by each group of workpiece clamping mechanisms can be heated and annealed, realizing the separate annealing of multiple groups, and effectively improving the working efficiency.

[0021] Each group of workpiece clamping mechanisms includes five equally spaced workpiece clamping mechanisms, and each workpiece clamping mechanism includes an electric telescopic column 7. The automatic chuck 8 is installed at the telescopic end of the electric telescopic column 7. A furnace cover 9 is installed on the automatic chuck 8. A clamping handle 10 is arranged on the upper end surface of the furnace cover 9. A fitting placement rack 11 is installed on the lower end surface of the furnace cover 9. A temperature sensor can be installed on the lower end surface of the furnace cover 9 for temperature control monitoring and prompting.

[0022] The heating mechanism includes a gantry 13, five induction heating coils 12, and five heating and heat preservation furnaces 14. The tops of the induction heating coils 12 are horizontally arranged in a row at equal intervals and fixed below the gantry 13. A heating fire pan is arranged inside the heating and heat preservation furnace 14, and the heating end of the heating fire pan corresponds to the bottom of the induction heating coil 12. The supporting part placing rack 11 is correspondingly arranged above the induction heating coil 12, and the heating and heat preservation furnace 14 is slidably arranged below the induction heating coil 12.

[0023] As Figure 3 shown, the gantry 13 is arranged at the right side of the fixed seat 1. Multiple heating and heat preservation furnaces 14 horizontally distributed evenly are grouped into multiple groups and rigidly installed front and back on the sliding seat 15. The sliding seat 15 is fitted and installed on the guide rail 16. The guide rails 16 are symmetrically arranged in two groups on the inner periphery of the gantry 13. The rack 17 is arranged on the upper end face of the guide rail 16. The gears 18 are symmetrically and rigidly installed in two groups on the gear shaft 19. The gear 18 meshes with the rack 17. The gear shaft 19 is fitted and installed on the sliding seat 15 through bearings, and the gear shaft 19 is rigidly installed at the power output end of the sliding reducer 20. The sliding reducer 20 is fixed to the housing of the sliding motor 21 through the reducer bracket. The sliding motor 21 is rigidly installed on the sliding seat 15 through the motor bracket. During production, the sliding of the heating and heat preservation furnace 14 can be realized through the action of the sliding motor 21, so as to realize the alignment and misalignment of the heating and heat preservation furnace 14 and the induction heating coil 12. When heating and heat preservation are required, it slides to the alignment of the two to realize the heating operation. When cooling is required, it slides to the misalignment of the two to stop heating the induction heating coil 12.

[0024] An automatic annealing device for processing plastic production equipment parts designed in this way has a reasonable structure design. Through the grouped workpiece clamping mechanism, multiple groups of parts can be effectively clamped, and the heating mechanism is used for heating by groups. At the same time, the heating of the heating mechanism is controllable, effectively improving the annealing heating efficiency, improving the automation degree of the annealing treatment, ensuring heating uniformity, and being beneficial to ensuring the annealing treatment effect.
