Abstract
The utility model relates to an extrusion cutting machine mouth plate, the main body is shaped like a step and is provided with a feed end with a feed runner and a discharge end with a discharge runner, and the feed runner is communicated with the discharge runner; the method is characterized in that: the orthographic projection of the discharge port of the discharge end is of an arc or conical structure, and a structure that the middle runner is long and the runners on the two sides are short is formed. The utility model has the characteristics of ingenious conception, reasonable design and stable extrusion quality; the unequal-length flow channels with the middle long and the two short sides of the discharge end are utilized to promote the rubber material to be redistributed to the two sides, so that the discharge thickness is more uniform, and the defect that the cut end surface is arc-shaped due to different stresses is overcome; in addition, the design of the port shape of the feeding port can distribute different amounts of rubber materials according to different pressures far and near the extrusion port, balance the defect of uneven flow velocity caused by large resistance at two sides of the flow channel, and is also helpful for improving the flatness of the cut end face.
Description
The technical field is as follows:
the utility model belongs to rubber is extruded and is equipped the field, in particular to extrude cutting machine die board for solve engineering machine tool radial tire in the production of wire cord fabric, cut the section and become the problem that arc and wire cord fabric middle thickness are greater than both sides thickness.
Background art:
because of the structural reason of the wirecord fabric extrusion cutting machine, rubber materials can be accumulated in the inner cavity of the machine head in the process of producing the wirecord fabric, so that the discharge pressure in the middle of the mouth plate can be greater than the pressures on two sides, the deformation quantity after the middle rubber material is extruded by the rubber material extruding speed machine in the production process of the wirecord fabric can be greater than two sides, and the extrusion cutting machine does not park to eliminate stress after producing the wirecord fabric, directly cuts the wirecord fabric, so that the thickness of two sides of the wirecord fabric is less than the middle thickness, and the cutting section of the cord fabric forms an arc-shaped defect.
How to overcome the scheme of above-mentioned defect through the improvement of mouth plate becomes the object of the utility model discloses research.
The invention content is as follows:
the utility model aims at designing an extrusion cutting machine die plate which can guide the feeding direction and reduce the stress on two sides of a flow passage.
The utility model discloses technical scheme realizes like this: a mouth-shaped plate of an extrusion cutting machine is provided, the main body of the mouth-shaped plate is step-shaped and is provided with a feeding end with a feeding runner and a discharging end with a discharging runner, and the feeding runner is communicated with the discharging runner; the method is characterized in that: the orthographic projection of the discharge port of the discharge end is of an arc or conical structure, and a structure that the middle runner is long and the runners on the two sides are short is formed.
The feeding runner at the feeding end is of a horn mouth structure, and the feeding port is of a mouth shape with large sides and small middle.
The feeding port of the feeding end is asymmetric left and right, and the side close to the extrusion port of the extrusion equipment is small, and the side far away from the extrusion port of the extrusion equipment is large.
The utility model has the characteristics of ingenious conception, reasonable design and stable extrusion quality; the unequal-length flow channels with the middle long and the two short sides of the discharge end are utilized to promote the rubber material to be redistributed to the two sides, so that the discharge thickness is more uniform, and the defect that the cut end surface is arc-shaped due to different stresses is overcome; in addition, the design of the port shape of the feeding port can distribute different amounts of rubber materials according to different pressures far and near the extrusion port, balance the defect of uneven flow velocity caused by large resistance at two sides of the flow channel, and is also helpful for improving the flatness of the cut end face.
Description of the drawings:
the present invention will be further explained with reference to the following specific drawings:

Wherein
1-feed end 11-feed runner 12-feed port
2-discharge end 21-discharge runner 22-discharge port
The specific implementation mode is as follows:
referring to fig. 1 to 3, the extrusion cutting machine die plate has a stepped main body, which has a feeding end 1 and a discharging end 2, a feeding runner 11 in the feeding end 1 is communicated with a discharging runner 21 in the discharging end 2, the discharging runner 21 is a straight cylindrical cavity, and the feeding runner 11 is a bell mouth structure so as to guide feeding and pressurize the feeding into the discharging runner 21; wherein, the discharge port 22 orthographic projection of discharge end 2 is the circular arc structure, constitutes the structure that the runner is long both sides runner is short in the middle of the runner to extrude the sizing material and can toward both sides redistribution in the middle of making the off-the-shelf thickness of shaping, reach the unanimity of middle and both sides, and maintain the middle part and the balance of both sides stress, guarantee to cut sectional straightness.
Further, the feeding port 12 of the feeding end 1 is in a shape of a large mouth at two sides and a small mouth at the middle, namely, a shape similar to a waisted shape, so that more glue is distributed at two sides; in the figure, two sides of a feeding runner 11 of a horn mouth are in smooth transition through inclined planes, and the runner resistance is reduced. In addition, the feeding port 12 is asymmetric left and right, and is small at the side close to the extrusion port of the extrusion device and large at the side far away from the extrusion port of the extrusion device, namely, the feeding port is properly adjusted according to the pressure difference with the extrusion port, so that the relative distribution of the rubber material in the flow channel is kept reasonable.
Referring to fig. 4 to 6, the main body is similar to the above example, except that the middle of the inlet port 12 is small and the two sides are large, the circular arc surface is used for smooth transition, and the orthographic projection of the outlet port is a conical structure, so that the ideal effect can be achieved.
