Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a trimming press apparatus that cuts and removes unnecessary objects such as burrs from various casts (workpieces) such as automobile parts obtained by casting aluminum or the like, and is particularly attached to a plurality of surfaces of the cast. The present invention relates to a trimming press device that cuts and removes unnecessary materials with a single facility.
[0002]
[Prior art]
Various machine parts such as automobile parts, for example, automobile cylinder heads, cylinder blocks, intake manifolds, and the like are manufactured by casting a metal such as aluminum. Since unnecessary products such as core sand, pouring gates, hot water and burrs are attached to the casting obtained by this casting, it is necessary to cut and remove the unnecessary products from the casting.
[0003]
As this kind of waste material cutting and removing device, a trimming press device that cuts and removes waste material adhering to a casting is conventionally known. For example, a holding jig for fixing and positioning a cast for each processing surface that requires cutting and removing unnecessary materials, and a dedicated trimming press cutter for cutting and removing unnecessary materials from the processed surfaces of the positioned castings. Devices equipped are known.
[0004]
[Problems to be Solved by the Invention]
However, this apparatus requires as many trimming press apparatuses as the number of processed surfaces that need to be removed. For example, in the case of a cylinder head of an automobile, a trimming press from two directions, ie, an upper surface side and a lower surface side is usually required. For this reason, two trimming press devices and a device for reversing the casting by 180 degrees are necessary, which requires a large installation space and a large equipment cost.
[0005]
Accordingly, an object of the present invention is to cut and remove unnecessary objects attached to a plurality of surfaces of a casting with a single equipment, thereby reducing the equipment space and reducing the equipment cost. It is an object of the present invention to provide a trimming press apparatus in which the disadvantages existing in the present invention are improved.
[0006]
[Means for Solving the Problems]
In order to achieve the above-described object, according to the present invention, a trimming press apparatus for cutting and removing unnecessary objects attached to a casting, a holding jig for fixing and positioning the casting, and a positioned casting A trimming press apparatus including a trimming press cutter that cuts and removes unnecessary objects from the trimming press apparatus, and a reversing mechanism that reverses the casting 180 degrees, and the trimming press cutter includes a plurality of cutters that are interchangeable, By replacing any of these cutters, it is possible to remove unnecessary objects on a plurality of surfaces of the casting with a single facility.
[0007]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
[0008]
FIG. 1 is a front view of a trimming press apparatus according to the present invention, and FIG. 2 is a side view of a trimming press mechanism in the apparatus of the present invention.
[0009]
As shown in FIG. 1, the apparatus of the present invention includes a trimming press mechanism A and a workpiece reversing mechanism B that reverses a casting (workpiece) by 180 degrees.
[0010]
As shown in FIGS. 1 and 2, the trimming press mechanism A includes a holding jig 2 that fixes and positions the workpiece 1, and a trimming press cutter 4 that cuts and removes an unnecessary object 3 from the positioned workpiece 1. . The trimming press cutter 4 includes a plurality of interchangeable cutters, for example, four cutters 4, 4... 4 in FIG. 1, and one of the cutters 4, 4. Unnecessary removal of a plurality of surfaces of the work 1 is made possible with the equipment of the stand.
[0011]
The above-mentioned trimming press cutters 4, 4,... 4 are arranged in parallel, for example, four along the peripheral surface 6 of a circular or square rotatable cylindrical press cutter index unit 5, and the units 5 are decelerated by an index method. By rotating the motor 7 in the direction of the arrow, the cutters 4, 4.
[0012]
As shown in FIGS. 1 and 2, the holding jig 2 also includes a plurality of holding jigs that can be interchanged, for example, four holding jigs 2, 2,... .. By replacing any holding jigs 2, 2... 2, and by operating a workpiece reversing mechanism B described later, a plurality of workpieces 1, 1. Can be cut and removed.
[0013]
For example, four holding jigs 2, 2... 2 are arranged in parallel along the peripheral surface 9 of a cylindrical holding jig index unit 8 that is rotatable such as a circle or a quadrangle. By rotating in the direction of the arrow with the reduction motor 10, the holding jigs 2, 2,...
[0014]
The work reversing mechanism B operates so that the work 1 on the holding jig 2 is sandwiched between the work gripping hands 11 and turned over. At this time, the workpiece 1 is reversed on the holding jig 2, and the waste 3 is cut and removed from both the upper and lower sides.
[0015]
The trimming press apparatus according to the present invention having the above-described configuration is operated as follows. First, the workpiece 1 is conveyed onto the holding jig 2 of the cylindrical holding jig index unit 8 by a workpiece conveying device (not shown), placed, fixed, positioned, and then the workpiece 1 is moved by the operation of the jig drawing mechanism 12. Is pulled into the trimming press position.
[0016]
Next, the trimming press lifting / lowering drive unit 13 is operated, and the cylindrical press cutter index unit 5 is lowered via the cutter lifting / lowering driving ball screw 14 to cut and remove the waste 3 of the workpiece 1. Thereafter, the unit 5 is raised, and the work 1 on the holding jig 2 is reversed by the operation of the work reversing mechanism B, and the unit 5 is lowered again to cut and remove the waste 3.
[0017]
Trimming press cutters 4, 4... 4 are selected or switched by driving the reduction motor 7 by the index method and rotating the cylindrical press cutter index unit 5 in the direction of the arrow, and holding jigs 2, 2 ... Selection or switching of the workpieces 1, 1 ... 1 on 2 also drives the reduction motor 10 by the index method to rotate the cylindrical holding jig index unit 8 in the direction of the arrow, and the desired holding treatment. This is done by selecting the tool 2. 15 is a frame.
[0018]
【The invention's effect】
As described above, the present invention is a trimming press device that cuts and removes an unnecessary object attached to a casting, and a holding jig that fixes and positions the casting, and an unnecessary object is cut and removed from the positioned casting. Trimming press cutter equipped with a reversing mechanism for reversing the casting 180 degrees and equipped with a plurality of interchangeable trimming cutters. It is possible to remove unnecessary materials.
