Description
Technical field
The utility model relates to equipment used in a kind of sheet heat forming, used clamping device when being specifically related to a kind of feeding.
Background technology
At present, sheet material, plastic sheet for example is generally by the moulding of vacuum thermoforming method.With the sheet material preheating, to sheet material negative pressure of vacuum method, the positive platen press of vacuum or the pressurization of vacuum mold platen press of preheating, cooling and curing molding cut at last afterwards earlier; In this process, need a conveyer, sheet material is transmitted between preheating zone, shaping area and curing area, simultaneously, cooperate with conveyer to be provided with clamp mechanism, in order to fixing sheet material when the extrusion forming.
In the prior art, clamp mechanism has two kinds substantially, the one, for sprocket-type, conveyer and clamp mechanism unite two into one, on the chain of the both sides of conveyer, be equipped with and collude tooth, the effect of playing the location simultaneously and transmitting, disclose a kind of Pneumatic hot plastic molding machine automatic feed sheet material mechanism as Chinese utility model patent CN2357904, its clamping device continuous distributed is arranged on the chain annular excircle, by two push rods, pressing plate, base plate, two springs, colluding tooth forms, collude tooth and penetrate the sheet material both sides, sheet material is positioned, it adapts to the thickness of sheet material by stretching of spring.This structure, though clamping positioning mechanism needn't be set separately, but on the one hand owing to variations in temperature in the process, collude tooth and easily cause the sheet material deformed damaged, simultaneously, fixing position is easy to make sheet material to produce distortion in the vacuum forming process only in the both sides of sheet material, thereby influenced product quality, increased the waste product loss.
Another kind is a clamping plate type, and two groups of clamping plate are housed in the both sides of conveyer, and when the sheet material after the preheating entered machining position, clamping plate moved up and down respectively, clamped sheet material, to play fixing purpose.This structure is because the clamping plate contact-making surface is big, itself can not impact sheet material, yet, in process, they as promoting the pressing plate or the power source of clamping plate, can be described as with atmospheric pressure and keep clamping force with air pressure, in case air pressure descends to some extent, popular saying is exactly to become flat, and clamping force will descend, and promptly influences the yields of sheet material; Simultaneously, they all need apply clamping force at the two ends of sheet material, and to guarantee equilibrium of forces, this just means two pneumatic supplies of needs; Moreover this structure is the fixing both sides of sheet material still, the stressed problem in both sides in addition of unresolved sheet material.
Summary of the invention
The utility model purpose provides a kind of sheet material that makes and be difficult for producing distortion, the clamp mechanism that can save power source simultaneously in process.
For achieving the above object, the technical solution adopted in the utility model is: a kind of sheet material clamp mechanism, it comprises clamp and drive mechanism, described clamp is formed with folder down by being distributed on two groups of sheet material transfer path both sides folder, folder and following folder one end are rotationally connected by connector on described every group, and the other end is provided with clamping device; Described clamping device is made up of stator and driving shaft, and described stator is provided with two groups of arc chutes, last folder with down be respectively equipped with the pin that matches with corresponding chute on the folder, described driving shaft is connected with drive mechanism; Be respectively arranged with between the folder between the folder and under two groups on two groups work in coordination on horizontal folder and following horizontal folder.
Sheet material is admitted between folder and the following folder by the connector end, the clamping device of the other end is under the rotation of driving shaft, last folder moves along arc chute with the pin that presss from both sides down, thereby make folder and press from both sides closure down, realize the purpose of clipping sheets, when the driving axial rightabout rotates, just can open clamping device.
In the technique scheme, described connector is the U type connector of horizontally set, and the described last pin of going up folder and U type connector is rotationally connected, and described folder down is rotationally connected with the leftover bits and pieces of U type connector.
In the technique scheme, described driving shaft is positioned at the center of stator, and described two groups of arc chutes are symmetrically distributed with respect to driving shaft.
Further technical scheme is, described drive mechanism comprises the fork that an end is fixedlyed connected with driving shaft, and the fork other end is connected with power source by linkage.
Another kind of technical scheme is, described drive mechanism comprises the gear of fixedlying connected with driving shaft in the axle center, and described gear is connected with power source by tooth bar.
In the technique scheme, described driving shaft is positioned at an end of stator, and described two groups of arc chute one end distances are from nearer, and other end distance is far away, and described drive mechanism comprises the gear of fixedlying connected with driving shaft in the axle center, and described gear is connected with power source by tooth bar.
In the technique scheme, described horizontal folder, down horizontal folder with describedly go up folder, be removable fixed connection structure between the folder down, wherein horizontal folder on a group, horizontal folder and corresponding going up are provided with at least 2 connections between folder, the following folder down; So-called removable fixed connection structure can be the pin formula, the also connection of bolt nut structure or screw and so on, and connecting the position simultaneously is the hole that is complementary with connected mode, to cooperate the needs of different length specification sheet material.
Another kind of technical scheme is, describedly horizontal folder, horizontal folder is the draw and insert-type structure down, with the needs of the sheet material that is fit to different in width.
Because the technique scheme utilization, the utility model compared with prior art has following advantage:
1. because the structure that the utility model adopts four limits to clamp has been strengthened making sheet material not yielding in process to desiring the fixation of working sheet, improved the yields of sheet material.
2. because an end of the present utility model is a fixing point, but the driving shaft that only needs to rotate other end clipping sheets just, thus the number of having saved power source.
3. owing to being not clamping force in the utility model medium power source, mechanical fixation promptly and only needs a rotatory force just can reach the purpose of clamping as clamping force, thereby has avoided becoming flat to the influence of product quality, has saved kinetic energy simultaneously.
