Definitions
- the invention relates to a rod for forming a Seiherkorbes for the delimitation of a compression chamber of a device for squeezing liquids, comprising a base on which an armor is fixed with at least one wear surface and at least one spacer element which is positioned laterally to a longitudinal extension of the Seiherstabes so in that it rises above a side surface of the crowbar.
- a wire rod with a welded-on bolt and a manufacturing method for a wire rod with a welded-on bolt are explained.
- the crowbar is provided for a substantially cylindrical wire basket composed of a plurality of crowbars for confining a compression space in a screw press for processing animal or vegetable products into meat meal and animal fat or vegetable oils and the like.
- the invention relates to a method for producing a rod which is delimited in the region of a wear surface by at least one pressing edge and which has at least one spacer element (bolt) which rises above the side surface in the region of at least one side surface of a base body.
- the invention further relates to a rod for a device for squeezing of liquids, which is limited in the region of a wear surface of at least one pressing edge and which has at least one over the side surface elevating spacer in the region of at least one side surface of a base body.
- the invention relates to a device for pressing off liquids, which has at least one strainer rod which is delimited in the region of a wear surface by at least one pressing edge and which has at least one spacer element which rises above the side surface in the area of at least one side surface of a base body.
- Colanders of the type mentioned in the introduction are used in the area of devices for pressing off liquid substances from substances introduced into the device. For example, it is possible to squeeze off liquid substances from oil-containing fruits, animal carcasses or slaughterhouse waste.
- the devices for pressing are formed like a drum and the Seirem rods extend in a longitudinal direction of the drum. In this longitudinal direction is also a transport of the substances to be processed. In the area of a drum outlet, the residual substances are discharged from the inside of the drum with virtually no moisture. Transport through the drum is accomplished using a pressure and transport screw.
- the tendrils are arranged at gap-like distances relative to one another.
- the cross-sectional area of the worm gear decreases from the inlet in the direction of the outlet.
- the gaps between the rods are usually given by spacer elements.
- the spacer elements are for example introduced manually as a spacer plate, also it is already known to connect such spacer plates by welding with the Seiherstäben. Due to the considerable forces acting during the pressing process, however, these arrangement methods for the spacer elements have the disadvantage that a slippage of the spacer elements can be caused, which causes the risk of a complete dropping out of the rods.
- the implementation of welding offers due to the risk of tearing off the welds no adequate security against slipping.
- the spacer elements are formed integrally with the rod rods and are produced by milling or grinding of the excess materials.
- such a production avoids slipping and leads to a high stability of the overall device, in view of the large number of Seiherstäbe used is compared to a use of loose spacers but causes a significant increase in manufacturing costs.
- the spacer elements are applied by a coating process on the base body, which is connected in the entire region of its the side surface of the base body facing boundary with the base body.
- the spacer element can be applied to the base body by build-up welding, laser welding or electrolytic coating.
- the high energy input into the base material which regularly leads to plastic deformation, which in turn adversely affects the component geometry.
- the object of the present invention is therefore to improve a method of the aforementioned type such that a still inexpensive production of Seiherstäben while preserving the component geometry during the manufacturing process and at the same time high reliability in the implementation of Abpressvorganges is made possible.
- This object is achieved in that as a spacer element, a metal element is connected to a pulsed welding process with the body.
- a plurality of Seiherstäben is arranged side by side within a Seiherkorbes.
- the rods have relative to each other a defined distance. This distance can be specified using spacers.
- spacer elements are welded to the rod.
- an electric welding preferably spot welding
- a variety of spacers is stored in this process in a magazine and the Welding device supplied.
- the spacer elements are typically designed bolt-shaped. Upon approach of the Seiherstab facing bottom of the bolt to the surface of the Seiherstabes ignites due to the applied electrical voltage an arc and the spacer element is welded to the rod.
- a machining process is carried out as a post-processing in order to bring the spacer element into the desired dimension, or only excess sawing off or cutting off excess lengths of the spacer elements takes place.
- a machining process is carried out as a post-processing in order to bring the spacer element into the desired dimension, or only excess sawing off or cutting off excess lengths of the spacer elements takes place.
- Fig. 2 is a side view according to viewing direction II in Figure 1 and
- Fig. 3 is a partial view of an enlarged cross section.
- FIG. 1 shows the cross section through a crowbar (1) in a first exemplary embodiment with at least one spacer element (30).
- the crowbar (1) is formed essentially by a base body (20), which basically corresponds to a metallic profile, and an armor (10).
- the armor (10) is preferably materially connected, for example by welding, to the main body (20) and has a wear surface (11) on its longitudinal edge, which preferably faces the press screw of the press device, to which a press edge (12) followed.
- the pressing edge (12) experiences a lateral boundary by a side surface (13), which is formed inclined relative to the vertical plane of the at least one end face of the spacer element (30) by an angle X.
- the wear surface (11) is opposite the connecting surface (14) by the angle Y inclined.
- Both the elements (10, 20) forming the rod (1) and the at least one spacer element (30) preferably have a minimum hardness of 55 + 4 HRC and are realized by a C45 material.
- the at least one spacer element (30) is designed in the embodiment of Figure 1 as a round profile and may for example have a diameter of 4 mm.
- the invention provides, in particular, an electric spot welding by pulse welding, in which the welding current is pulse-modulated in order to transfer the heat introduced by this welding process into the rod element (20). to limit to as small a local area as possible.
- the heat input into the base body (20) must be kept as low as possible and limited locally, so that the distortion is minimized by thermal stresses and, secondly, especially in the welding of the armor (10 ) adjacent spacer element (30) the possible limited to a small area at the welding point heating important to the connecting surface (14) of the base body (20) and armor (10) as little as possible thermally stress. If the thermal load on the bonding surface (14) is too great, there is a risk that the strength of the joint will drop and the armor (10) will come off, which can cause considerable device damage to the press.
- FIG. 2 shows a side view according to the viewing direction II in FIG. 1.
- the spacer elements (30) are arranged symmetrically in this embodiment.
- FIG. 3 shows an area of the cross section according to FIG. 1 on an enlarged scale.
- the column width Z is the resulting clear width between adjacently arranged tendrils (1) on the side surface (13) within the seed basket.
- the gap width Z is primarily influenced by the angle of the side surface X as well as the length of the at least one spacer element (30) and the position of the end face of the spacer element (30).
