wp_title filtering out site name

Hi thanks for your reply
I am using my own theme based in underscore.
I thought the page title and blog title were default to wp_title I simply want to over ride this so that I only see the page title

Any suggestions.
Thanks

Hi thanks for your reply can you tell me what I would need to edit to remove blog title:

function hivservices_wp_title( $title, $sep ) {
		if ( is_feed() ) {
			return $title;
		}

		global $page, $paged;

		// Add the blog name
		$title .= get_bloginfo( 'name', 'display' );

		// Add the blog description for the home/front page.
		$site_description = get_bloginfo( 'description', 'display' );
		if ( $site_description && ( is_home() || is_front_page() ) ) {
			$title .= " $sep $site_description";
		}

		// Add a page number if necessary:
		if ( ( $paged >= 2 || $page >= 2 ) && ! is_404() ) {
			$title .= " $sep " . sprintf( esc_html__( 'Page %s', 'hivservices' ), max( $paged, $page ) );
		}

		return $title;
	}
	add_filter( 'wp_title', 'hivservices_wp_title', 10, 2 );

	function hivservices_render_title() {
		?>
		<title><?php wp_title( '|', true, 'right' ); ?></title>
		<?php
	}
	add_action( 'wp_head', 'hivservices_render_title' );
endif;
