Hi @stockholm

I think you need something like the below:

<?php
add_action( 'transition_post_status', 'acf_generate_custom_url', 10, 3 );
function acf_generate_custom_url( $new_status, $old_status, $post ) {

    #only apply this to a particular post type 	
	if ( 'publish' !== $new_status or 'publish' === $old_status || 'product' !== get_post_type( $post ) )
	return;
	
	if ( defined( 'DOING_AUTOSAVE' ) && DOING_AUTOSAVE )
	return;	
        
        #get custom fields
        $field_1 = get_field('field_1');
		$field_2 = get_field('field_2');
		$field_3 = get_field('field_3');
	
		#join field data
		$new_permalink = $field_1.' '.$field_2.' '.$field_3; #you can remove the space if you need      
                
        #get the post data
        $my_post = array(
            'ID'        	=> $post->ID,
			'post_title'	=> $new_permalink, 	#update title
            'post_name'		=> $new_permalink	#update slug
        ); 
    
        #update the post into the database
        wp_update_post( $my_post );

}

Code is untested but should get you pretty close
