Description

Technical Field

[0001] The invention mainly relates to the technical field of thermoforming, and in particular to an indirect thermoforming preheating production device. Background Art

[0002] Thermoforming is a special plastic processing method that processes thermoplastic plastic sheets into various products. The complete process of indirect thermoforming is: blanking on the cold stamping line, preforming, trimming and punching, sending to the heating furnace to heat to austenitization, sending to the mold for shape preservation-quenching, cleaning and oiling.

[0003] At present, indirect thermoforming preheating production equipment often requires manual lifting of the raw materials of the thermoformed parts so that the raw materials are placed on the equipment. This method is time-consuming and labor-intensive, and affects the thermoforming processing of the thermoformed parts. Summary of the invention

[0004] The present invention mainly provides an indirect thermoforming preheating production equipment to solve the technical problems raised in the above background technology.

[0005] The technical solution adopted by the present invention to solve the above technical problems is:

[0006] An indirect thermoforming preheating production device comprises a base, a top end of the base is connected to a lifting mechanism, a top end of the lifting mechanism is connected to a top plate, and a top end of the top plate body is connected to a sliding mechanism;

[0007] The sliding mechanism comprises a slide groove arranged on the top of the top plate body, and a material receiving slide plate slidably connected to the slide groove body;

[0008] The top of the base is connected with a traction assembly, and the traction assembly is connected with a material-carrying slide plate.

[0009] Furthermore, the material receiving slide plate includes a sliding plate slidably connected to the slide groove body, and a material receiving plate connected to the top of the sliding plate. The sliding plates are provided with multiple ones. In the present invention, the sliding plate slides in the slide groove body so that the material receiving plate can be translated. Through the translation of the material receiving plate, the hot-formed parts raw materials placed on the material receiving plate are driven into the preheating furnace and the raw materials can be extracted from the preheating furnace.

[0010] Furthermore, a plurality of balls are embedded in the bottom end of the sliding plate, and the sliding plate is slidably connected to the trough body of the slide groove through the balls. In the present invention, the friction between the sliding plate and the trough body of the slide groove is reduced by setting the balls.

[0011] Furthermore, the traction assembly includes a traction rope connected to the top of the base, and the end of the traction rope away from the base is connected to the sliding plate. In the present invention, when the top plate is raised or lowered, the sliding plate connected thereto is pulled by the traction rope, thereby driving the sliding of the material receiving plate.

[0012] Furthermore, the traction assembly also includes a convex plate connected to both sides of one end of the top plate body, and symmetrically arranged traction rollers are connected between the two convex plates. A gap is provided between the two traction rollers for the traction rope to pass through. In the present invention, the convex plate is used to provide support for the traction roller, and the traction rope is guided by the traction roller to enable the traction rope to move smoothly.

[0013] Furthermore, a groove is provided at the bottom end of the sliding plate, and the groove is used for allowing the traction rope to pass through. In the present invention, the groove is provided to allow the traction rope to pass through, thereby providing sufficient space for the movement of the traction rope.

[0014] Furthermore, one end of the material receiving plate away from the traction rope is connected to a counterweight rope, and one end of the counterweight rope away from the material receiving plate is connected to a counterweight block. The counterweight rope is slidably connected to the inclined groove, and the inclined groove is arranged in the groove body of the slide groove. In the present invention, when the top plate descends, the counterweight rope is pulled by the counterweight block to make the counterweight rope fall along the inclined groove. In this way, the material receiving plate returns, thereby making it convenient for workers to prevent the raw materials from remaining on the material receiving plate.

[0015] Furthermore, the lifting mechanism includes fork arm links symmetrically arranged between the base and the top plate, and a power component is connected between the two fork arm links. In the present invention, the first cross bar connected to it is pushed by the extension and contraction of the cylinder, thereby changing the distance between the first cross bar and the second cross bar. Since the first cross bar and the second cross bar are connected between the two fork arm links, the two fork arm links are driven to rotate relative to each other.

[0016] Furthermore, the power assembly includes a first cross bar and a second cross bar connected to the fork arm connecting rods at opposite ends, and a cylinder connecting the first cross bar and the second cross bar, and bearing protrusions are connected to both ends of the cylinder, and the two ends of the cylinder are rotatably connected to the first cross bar and the second cross bar respectively through the bearing protrusions.

[0017] Furthermore, the fork arm link includes a first link and a second link connected between the base and the top plate, the first link and the second link on the same side are connected to each other, the bottom end of the first link is rotatably connected to the inside of the base, and the top end is slidably connected to the bottom end of the top plate body, and the bottom end of the second link is slidably connected to the inside of the base, and the top end is rotatably connected to the bottom end of the top plate body.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] Firstly, the present invention pushes the first cross bar connected to the cylinder through the extension and retraction of the cylinder, thereby changing the distance between the first cross bar and the second cross bar. Since the first cross bar and the second cross bar are connected between two fork arm links, the two fork arm links are driven to rotate relative to each other. The relative rotation of the two fork arm links drives the lifting and lowering of the top plate connected to the two fork arm links. By lowering the top plate, the raw materials can be placed on the receiving plate at the top of the top plate.

[0020] Secondly, when the top plate is raised or lowered, the traction rope is used to pull the sliding plate connected to it, thereby driving the sliding of the material receiving plate. The sliding plate slides in the slide groove body so that the material receiving plate can be translated. Through the translation of the material receiving plate, the hot-formed parts raw materials placed on the material receiving plate are driven into the preheating furnace and the raw materials can be drawn out of the preheating furnace.

[0032] A traction assembly 11 is connected to the top of the base 10 , and the traction assembly 11 is connected to the material receiving slide plate 42 .

[0034] A plurality of balls 423 are embedded in the bottom end of the sliding plate 421, and the sliding plate 421 is slidably connected to the groove body of the sliding groove 41 through the balls 423;

[0035] It should be noted that, in this embodiment, the sliding plate 421 slides in the groove body of the slide groove 41, so that the material receiving plate 422 can be translated, and the translation of the material receiving plate 422 drives the hot forming material placed on the material receiving plate 422 to enter the preheating furnace and the material can be drawn out of the preheating furnace;

[0037] Furthermore, by disposing the ball bearings 423 , the friction between the sliding plate 421 and the groove body of the sliding groove 41 is reduced.

[0040] A groove 4211 is provided at the bottom end of the sliding plate 421, and the groove 4211 is used for the traction rope 111 to pass through;

[0041] It should be noted that, in this embodiment, when the top plate 30 is lifted or lowered, the sliding plate 421 connected thereto is pulled by the traction rope 111, thereby driving the sliding of the material receiving plate 422, and the traction rope 111 is connected to the sliding plate 421 near one end of the counterweight rope 424;

[0042] Furthermore, the convex plate 112 provides support for the traction roller 113, and the traction rope 111 is guided by the traction roller 113 so that the traction rope 111 moves smoothly;

[0043] Furthermore, the groove 4211 is provided to allow the traction rope 111 to pass through, thereby providing sufficient space for the movement of the traction rope 111.

The counterweight rope 424 is slidably connected to an inclined groove 426, and the inclined groove 426 is provided in the groove body of the slide groove 41;

[0045] The lifting mechanism 20 includes a fork arm connecting rod 21 symmetrically arranged between the base 10 and the top plate 30, and a power assembly 22 is connected between the two fork arm connecting rods 21;

The two ends of the cylinder 223 are rotatably connected to the first crossbar 221 and the second crossbar 222 through the bearing protrusions 224.

[0047] The fork arm link 21 includes a first link 211 and a second link 212 connected between the base 10 and the top plate 30.
